    Description: [0001] The invention relates to a device for discharging multicomponent adhesives having at least two fluid components onto a granular mixture, in particular for discharging multicomponent adhesives onto the gravel of a railroad railway track. In this case, the two fluid-like components are conveyed from storage tanks by means of gear pumps in exactly controllable flow rates via two separate supply lines via a mixer unit, whereby a fluid sprayable adhesive mixture is produced. A spray unit with a spray bar with several discharge nozzles serves for targeted discharge of the adhesive mixture onto the ballast bed. Furthermore, the invention relates to a method for employing this device and its use for discharging multi-component adhesives onto the ballast of an iron rail track.
    Railways are today an important component of the infrastructure in the long-distance as well as in local traffic. It is not always the case that the track superstructure can cope with the increasing traffic load. With increasing speed, greater traffic loads or higher intensity of use, weaknesses of the different types of construction become apparent. Track renewal is, in addition to regular maintenance, necessary measures to meet the increased demands. As a base course dominated in long-distance traffic, the gravel superstructure. In urban public transport, on bridges or in tunnels, on the other hand, the formation of a fixed carriageway can be found. For both embodiments and in the connection of different lanes adhesive systems offer an efficient problem solution. In the ballast track as a route is the loosely laid track grille rails and sleepers without a lateral attachment in this unbound, compacted ballast bedding. The ballast bed can absorb considerable pressure forces, but is only displaceable under tensile load. Adhesive systems secure the positional stability quickly and permanently in difficult areas such as rail bumps or points. For conversion work and track renewal on multi-track routes special measures to secure the position of the ballast bed are necessary. The bonding of gravel shoulders with two-component Flarz-Flärter mixtures has proved to be an effective method for this purpose. Compared to conventional fixation measures, the use of a fast-curing adhesive system saves a great deal of time and costs. A particularly difficult area for railways is the integration of different types of construction. Transitions between a ballast track and a slab track are problematic because of the different settlement behavior. Here, the gradual bonding of the ballast has proven to be an effective measure for the equalization of different elasticities. Also for this adhesive systems offer special advantages, namely short waiting times to capacity and a very good environmental impact of the adhesive system. In inner-city suburban traffic, it is above all slab tracks and lawn tracks that determine the image of the railways. Also for these embodiments, the two-component blends provide efficient detail solutions for the stabilization, sealing and design of the track systems.
    The bonding of granular mixture is therefore used today in a variety of applications. In track construction, especially coarse-grained rock fillings and gravel are bonded, in road construction in addition to coarse-grained riprap, however, also small-grained riprap or grit. Even finer mixtures are used, for example, in the bonding of decorative top floor coverings. Despite the stabilization by the bonding of the covering whose water permeability or seepage can be obtained. Of particular importance is the bonding of gravel in track construction. For this purpose, the adhesives used today are mostly two-component adhesives based on polyurethane. Such polyurethane-based multi-component adhesives are known in the prior art, for example from WO 2011/110 489 A1. Also devices controlled pumping, dosing, mixing together and applying such adhesives, including by means of gear pumps is known in principle, such as CN 101 850 312 A, DE 19 632 638 A1 or WO 2014/176 589 A1.
    The bonding of gravel in track construction, various positive effects are achieved. Among other things, it enables the stabilization of the tracks and the reduction of bumps at transitions from the ballast track to the fixed track, for example at tunnel entry points or tunnel exits. For this purpose, the gravel is usually glued over the entire surface, including under the rails and sleepers. In order to achieve a reduction of the bumps at the transitions between the ballast and the fixed track, the penetration depth of the bond to the fixed track is successively increased. By gluing the ballast in addition to the ride comfort but also the longevity of the roads can be improved because a displacement of the stones is prevented.
    Often, a bonding of the ballast bed in the edge region of a rail track is crucial if a trench to be dug near the rail line, or if quite apart from the rail track as a result of a construction project, such as the laying of another parallel rail track or a building, a Retaining wall, etc. or because of other structural measures material to be excavated. With such excavation, the ballast bed will otherwise be weakened and its carrying capacity will not be granted. Trains with their heavy weights could not pass this spot anymore. As a countermeasure, although a deep spurt or an auxiliary wall could temporarily ensure the stability, so that the rail track could continue to be used. Much easier but it turns out to glue the gravel along the side at which such structural changes are to be made, which would otherwise weaken the bulkhead route significantly. Thus, by gluing the ballast bed on a strip on the side of the road, a stable ballast shoulder can be produced very quickly. This shoulder proves to be advantageous in the laying and maintenance of control and signal lines along the tracks, because outside the bonded area a trench can be easily excavated and the laid control and signal lines thanks to the defined stable shoulder of the ballast bed exposed and after renewal the trenches of the trenches can be filled up again without affecting the basic shape of the ballast bed. The stabilized by bonding ballast bed shoulder remains despite the dug right next to the rail track trench continue to travel with the usual loads. In the case of a professionally glued gravel road this can be tapped to some extent sideways and immediately next to the ballast bed, for example, an excavation can be made. Thanks to the bonding, the necessary stability of the gravel road for familiar driving on trains is retained, which offers enormous advantages.
    However, the discharge of the adhesives for producing such a stable bonding requires that the adhesives are always applied in the correct mixing ratio, the penetration depth of the mixed adhesive into the ballast bed reaches a precisely predetermined depth everywhere and also the amount of adhesive at a defined Spraying width per running meter is held exactly constant. Next, such a bond not only over a few meters, but can be made quickly and reliably over larger sections. All the necessary boundary conditions must be meticulously met, such as the temperatures of the adhesive components, an absolutely constant, continuously monitored mixing ratio, a uniform discharge over the treatment line with a constant speed of the spray over the ballast to maintain a constant penetration into the ballast bed, only This ensures that the gravel is bonded to a defined depth with a precisely defined amount of adhesive per gravel volume, depending also on the size of the stones of the ballast and the desired penetration depth. Only if these specifications meticulously met, such a bond can be certified in the sense that a railway train of a certain weight may continue to drive a track section laterally of which construction measures are taken as mentioned above, ie trenches for pipelines or retaining walls or excavations of all Art be dug.
    According to the prior art, the discharge of such adhesive mixtures is so far less professional, cumbersome and error-prone, that is not regular, and above all very less efficient. The discharge takes place manually by means of watering cans or by hand lances, with manual or motor-operated pumps. The two basic components of the adhesive are for example carried on a railway carriage and mixed on this. Subsequently, the mixture is filled into Giesskannen or fed via a line directly to the hand lances. To glue a m3 of gravel requires 15 liters of adhesive mixture and when applying by means of a watering can only about 4 m3 gravel per hour can be treated. In addition, the Ausbringqualität is largely uneven, since it depends on the skill of the person who pours with the watering can or operated the hand lance and thus walk along the railway rail track. It is immediately clear that with it an effectively uniform spray jet with uniform speed can not be guided over the same while maintaining a constant distance to the ballast. Accordingly, a bond produced in this way can not be certified in the sense that the trafficability of the rail line can be guaranteed while the ferry operator continues to enjoy full insurance cover. This is of great importance for trains with high loads of several 100 tons. An accident due to a weakened gravel bed with possibly overturning of freight or tanker vehicles and in the worst case discharge of toxic substances into the ground would have enormous consequences for the insurance, which is why a recognized by the insurance certification of a bond for the normal driving on the rail line was not possible, but would be crucial.
    When a discharge of the adhesive by hand done immediately interruptions of the discharge to refill a watering can, or to advance the replenishment, that is, the container and the machinery for pumping the adhesive to the lance in stages, because these containers and devices are either carried on a railroad car or transported on the road and placed side of the rail section. If, for some reason, a malfunction occurs, such as a pump malfunctioning or failing, spraying a single, inherently toxic component can occur in greater quantities, which can have fatal consequences for the groundwater. The components may namely be applied intimately mixed only in the prescribed mixing ratio. Then the mixture hardens reliably and no individual component can get into the ground in isolation.
    The bonding must be done quickly and determines the depth of penetration, because the applied adhesive runs down through the ballast and by soon glued and hardened, the penetration depth is limited. As a rule, work must be carried out outside the hours of operation and often at night, and dry weather is a prerequisite for applying the adhesive. It can be seen that there are many boundary conditions and the result is the requirement that a uniform discharge with precisely defined specifications should be done mechanically reliably and very quickly on site.
    If a bond anywhere on a rail section done, such as in a train station, or in hard to reach places such as bridges, underpasses or overpasses, or generally in places where the rail track is not accessible to the side of vehicles, so it is a special The challenge of being able to carry out a uniform discharge there quickly, if possible in an instant, ie without any interruptions. If one calculates with about 15 liters of adhesive mixture per m3 of track ballast to be treated, these reach at half a meter of bed depth to be bonded and a half meter bed width at the side of the rail for 8 linear meters, and then two 200 liter drums are sufficient for a little more than 200 meters rail section, and if the bonding is to take place over the full ballast bed width, only a section of about 50 meters can be glued in one pass.
    A particular challenge for the rapid and controlled discharge of adhesives in perfect mixture and with a constant depth of penetration over long distances in a hurry is the fact that large masses are needed for the necessary machinery and the reservoir. For example, powerful pumps are needed. Furthermore, a self-sufficient energy supply is necessary, both for the pumps and for heating the auszubringenden components that must be available in large quantities. And then all these facilities should be able to be moved along a route. If you wanted to use a railroad car, which could then be pulled or pushed, it would be much too heavy for a road transport, and the insertion in a rail section would have to be done with large crane trucks. Such a device would be too cumbersome to be flexible and quickly deployable. If one were to carry all the facilities with a truck along a railroad track, it could not travel along the railroad tracks in many places, but could only be used on open terrain.
    Various devices for the controlled mixing of components into a defined mixture are known in the prior art, but there are no known devices that this controlled and precise application of adhesives for the bonding of ballast beds along rail tracks over many hundreds of meters in a hurry and quickly and flexibly operational.
    Object of this invention is therefore, in view of the situation as described above to provide a device by means of which the ballast bed of a rail track section over its entire width or over a selectable part of its width over any distance to 6 km in one go a two-component adhesive with a minimum of personnel, namely of only two people is glued, the device should be transportable on a single stras-transportable vehicle or trailer to the place of use, anywhere quickly be used on the rails of the section to be treated self-propelled, and with which a two-component adhesive controlled and continuously monitored in a uniform, selectable speed and with definable application rates per time and thus defined penetration depth in precisely determinable areas in the ballast bed in selectable spray patterns can be applied.
    The solution of the problem is defined by a device having the features of claim 1, as well as by the method of claim 11 and the use of claim 15. This device can be transported by road and then driven on the rail to any point of a railway connection, in many cases even transported by road exactly to the place of use. It can be placed there on the rail and be put into operation within a few minutes and removed just as quickly from the rail section to release the passage after Verklebearbeiten again. The device allows the controlled application of the adhesive in precisely defined quantities and mixing ratios, with automatic feed and thus ensuring a defined penetration depth of the adhesive into the ballast bed. The device is energy self-sufficient and automatically controllable.
    With reference to the drawings, the result of such bonds is first shown. Then, this device for generating the bonds is presented and described and its functions are explained. Then, the method and the use of the device that can be carried out are described and explained in more detail. For this purpose, the drawings, for example, embodiments of the device, and also the task and the purpose of the invention will be shown and explained with reference to the drawings.

    In Fig. 1, an application is shown, namely a scored just outside along a rail track scooped screed, which was previously glued by spraying a two-component epoxy resin, so that it forms a quasi-monolithic block. In this condition, the scoop trench can be tapped with an excavator bucket as shown here, yet it remains stable so that vertical walls can be exposed without the scoop trench substantially losing its structural strength and stability. When, for example, cables or pipes have to be routed along such a rail track, there are great challenges in maintaining the stability of the rail track if it is to continue to travel on trains, ie during the installation work for the pipes and pipes. Without the possibility of track stabilization, the rail track would have to be closed to rail traffic, which would mean major restrictions and costly outages for rail operators.
    Fig. 2 shows another stabilized by bonding and then tapped gravel road along a rail track in front of a tunnel portal. As you can see, a trench often has to be dug over considerable distances, and here is the problem of how to stabilize a gravel road over large distances so reliably and safely that the later tilled route for driving on trains with normal load certified can be. No one can guarantee the homogeneity of the bond when hand-discharging. In addition, the gluing by hand is much too slow, is labor-intensive, inaccurate and correspondingly expensive. This is where the present invention applies and makes it possible, in a completely different dimension, to bond the bulkhead courses, much faster and more efficiently, with complete homogeneity, with exactly the same selectable width of the bond and with an accurately definable penetration depth of the adhesive throughout the entire bond. Only such a machine discharge of the adhesive can be done so accurately that the bonding and stabilization is certifiable, so that a railway operator can have the certainty that fully loaded trains without further ado can safely drive this glued route and insurance.
    Fig. 3 shows this example, a device for dispensing the adhesive, consisting of three cars, seen in a schematic view from above. The decisive solution for realizing a stras-transportable device that can be operated by only two people, it is that the device is either built directly on a rail-road vehicle, which is directly on a track auffahrbar and drivable on site, or but that it is divided functionally, in at least two or three units or two or three separate cars that are charged separately on a road vehicle or a road trailer and again abladbar and thus separated, or separately from just two people on the Rails of a rail track can be placed. A single car weighs about 350 kg, and only the car with the component containers, empty about 250 kg, is heavier, depending on the load, up to 2000 kg. By contrast, if the facility were built as a one-piece machine, it would work, but its handling and transportation would be much more complicated. It would hardly be loadable by a small amount of personnel and without a crane to a vehicle and placed on a rail track. In addition, it would be technically very demanding to bring such a heavy equipment to the site and put there on the rails.
    And so Fig. 3 shows an inventive device on rail cars, which are parked on railroad tracks 4, shown schematically from above, in plan view. The railroad tracks 4 are here on the crossbar 5, which are embedded in the gravel road 6. The composition of rail cars here consists of three units that can be coupled together and also easily separated again. The foremost unit forms a Sprühwagen 1 with four rail wheels, followed by a first trailer as a container car 2, also with four rail wheels, and a rear attached to this second trailer with four rail wheels as energy supply 3. These trailers 2, 3 are detachable drawbars. 7 , 8 coupled together. The cars are equipped with spherical hooks for this purpose. For example, each of the drawbars can be made from two conventional passenger trailer drawbars, so as to obtain a drawbar 7,8 in the form of a single rod of about half a meter in length, which has a coupling socket at both ends. On the spray 1 you can see the two supply lines 9, 10 for the two components of the epoxy resin mixture. They lead through two gear pumps 11, 12 which are each driven by an electric motor 13,14 precisely controllable. From the gear pumps 11, 12, the supply lines 9, 10 continue to pass through a respective mass flow meter 15, 16 and finally to the spray bar 17, where they lead via a Y-shaped combination to one or more spray nozzles. The spray bar 17 can be displaced over a horizontally extending boom 18 extending across more than the width of the spray carriage so that spraying is possible to the right or left of the cart or in any position therebetween. The spray bar 17 can be pivoted about its vertical axis, as needed, to vary the spray width. Pneumatic valves 19, 20 are installed in front of the spray nozzles to stop the flow sharply when needed. Pulled by the coupling rod 7 follows behind the spray 1 of the container wagon 2, which carries here two 200 liter barrels 60, 61, for the two components A and B of the epoxy adhesive. About another coupling rod 8 of the rearmost car, namely the power supply car 3 is pulled.
    The self-propelled unit, that is, the spray 1, is shown in Fig. 4 seen in a view from the front. Below the rails 4 can be seen the ballast bed 6, which consists of a granular mixture of a plurality of ballast stones 21, wherein in Fig. 4 only on one side of such ballast stones 21 are indicated. The sprayer 1 includes a chassis 22 with two axles 23 and four wheels 24. The wheels 24 on both sides of the carriage are slidable on their axles 23 along the axes and provided with a mechanical coupling so that they move symmetrically outwards or inwards. That is to say the wheels 24 of all carriages 1, 2, 3 are part of a lane change system, with which the carriages 1, 2, 3 can be used on the largest occurring track widths up to the narrowest track gauge widths. The wheels on at least one of the axles 23 can be driven by a 24V electric traction motor 25. On the self-propelled spray 1, a first gear pump 11 with an associated speed-controlled electric drive 13 is arranged to control the flow rate of the first component A. From this first gear pump 11, a section of a first supply line 9 leads to a first, but not shown here mass flow meter, which serves to detect the flow rate. From the mass flow meter, a further section of the first supply line 9 leads to a first controllable pneumatic valve 19 and further to a first check valve and flows through a Y-fitting 26 into a mixer unit 29. Parallel to this is an identical second gear pump 12 for the second component B. arranged with an associated speed-controlled, electric drive 14. From the second gear pump 12, a portion of a second supply line 10 leads to a second, not shown here mass flow meter, and on to a second controllable pneumatic valve 20 and then to a second check valve into the mixer unit 29. The mixer unit 29 includes in the interior a static mixer, for example in the form of an approximately 10 cm long grid-shaped structure or a helical mixer, and is attached to a boom 18. An average inner diameter of the supply lines 9, 10 measures for example 1.5 cm. At the fluid outlet side 33 of the mixer unit 29, a discharge device in the form of a spray bar 17 is attached. The spray bar 17 consists of a horizontally extending hollow cylindrical profile with, for example, five spaced-apart and interchangeable flat jet nozzles 30 each having a nozzle diameter of, for example, 5 cm. 1 mm. Each of the flax jet nozzles 30 can thereby generate a fan-like jet 31. The flat jet nozzles 30 are arranged side by side so that the steel 31 which can be produced therewith form, in a region 32 to be sprayed on the ballast bed 6, a continuous flat or curtain-like overall jet. A spray width of the total jet in the application area 32 on the ballast bed 6 is, for example, about 55 cm. The distance between the flat jet nozzles 30 and the ballast bed is approximately 40 cm.
    Fig. 5 shows a block diagram with all means for pumping and mixing of the components into a sprayable mixture on the Sprühwagen. As shown, the two electric drives 13, 14 of the two gear pumps 11, 12 can each be controlled by the control unit 34 by outputting two independent output signals via a respective control line 35, 36. This allows the delivery rates of the two gear pumps 11, 12 and thus the flow rates in the two supply lines 9, 10 are controlled independently. The flow rates in the two supply lines 9, 10 can be detected independently of one another, monitored and processed in the control unit 34 via the signal lines 37, 38 between the two mass flow meters 15, 16 and the control unit 34.
    Via further signal lines 39, 40 between the control unit 34 and the two pneumatic valves 19, 20, these can be opened and closed. Behind the pneumatic valves 19, 20 each followed by a check valve 27, 28. Between the control unit 34 and the 24V traction motor 25 there is a further signal line 41, which allows control of the speed of the Sprühwagens 1. The control unit 34 has a microprocessor control with a memory and a computing unit. In the memory, the mixing ratios to be maintained between components A and B, the desired flow rates or total flow rates and the speed of the spray carriage 1 can be entered and stored as setpoints, for example, via the control unit or an input interface. The arithmetic unit is programmed so that it executes a control program, which ensures that the mixing ratios between the components A and B and the flow rates are met exactly to a few percent. For larger deviations, the discharge of components A and B is automatically stopped.
    Thus, e.g. between the two gear pumps 11, 12 each have a pressure relief valve in the supply lines 9, 10 are integrated and the output of the pressure relief valves can be equipped with return lines, with which exiting an open pressure relief valve fluid component A or B in an associated section of the supply line before associated gear pump 11 and the gear pump 12 can be returned. In principle, the mass flow meters 15, 16 can also be omitted, and instead additional position sensors can be provided on the gear pumps 11, 12 and / or the associated drives 13, 14.
    As further shown in the block diagram of Fig. 5, a speed sensor 43 may be provided, which transmits information about the current driving speed of the Sprühwagens 1 via an associated signal line 44 to the control unit 34. This makes it possible to precisely control the throughput of the two fluid-shaped components as a function of the respective current speed of the spray carriage 1. Further, for example, the discharge device or the spray bar 17 can be arranged along the boom 18 movable. For this purpose, e.g. a rack drive can be used. Due to the mobility, the width of the sprayable area 32 can be massively increased. The control of the movement of the spray bar 17 of the discharge device may in turn be controlled by the control unit 34 and e.g. be synchronized with the speed of the Sprühwagens 1 and the flow rates. Furthermore, it is possible to provide a sensor 45, which is indicated in the block diagram of FIG. 5, with which the nature of the area to be sprayed can be continuously checked and transmitted to the control unit 34 via the signal line 46. For this purpose, for example, ultrasonic sensors and / or laser-based sensors can be used. This can not be detected areas such as sleepers 5 or rails 4 detected automatically and the discharge when crossing these areas can be interrupted. This saves on the one hand adhesive and on the other hand reduces the effort, since these areas do not need to be covered in advance. Next can be attached to the spray 1 additional panels, which prevent, for example, that the rails 4 are coated during dispensing with adhesive. Overall, the application of the two mixed components A, B can be fully automatic by controlling everything from the programmable controller 34. It ensures that the whole device with its carriage composition with uniform speed and uniform discharge of the adhesive on exactly prescribed width and in such a quantity that just the right depth of penetration is maintained. It can also be programmed that the penetration depth varies over a certain distance, that is about steadily deeper, or from a certain depth is steadily less deep.
    In Fig. 6, the device is shown as a composition of three cars, with vorderst the spray 1, which weighs in the order of about 350 kg. On the first trailer, the container car 2, which is coupled directly to the self-propelled spray 1, there is a first barrel-shaped container 60 with a liquid polyurethane resin and a second barrel-shaped container 61 with a liquid hardener. The liquids present in the two containers 60, 61 are the components A, B of a two-component polyurethane-based adhesive. This container wagon weighs about 250 kg, and when fully loaded up to 2000 kg, depending on the capacity of the loaded containers. From these barrels or containers 60, 61 lead the supply lines for the adhesive components A, B to the spray 1 and finally after mixing together by combining in a mixer, for example a spiral mixer, to the spray nozzles on the spray bar 17. The viscosities of the two liquid Components are in the range of approx. 200 mPas. The two containers 60, 61 have e.g. a content of 200 liters, with larger or smaller containers can be used. As a special feature, these containers 60, 61 are adjustable in receiving recesses in the top of an otherwise hollow box, the interior of the box acts as a sump 56 in the event of leakage and is heated and ventilated to always the components A, B at their ideal temperature hold. The heating can be a temperature controlled electric or a gas heating, with propane gas, as usual on campsites. The container trough 56 is also equipped with a ventilation, of which one here the vent tube 70 recognizes, which also serves to temper the components, if they are warm in the summer. In this case, a further section of the first supply line 9 connects the first container 60 with the first gear pump 11, and a further section of the second supply line 10 connects the second container 61 with the second gear pump 12.
    In the second trailer, the power supply car 3 with a weight of the order of 350 kg a diesel engine and switchable power-generating diesel generator with 400 V output voltage is housed, and a compressed air generator with compressed air tank, the compressor is also driven by the diesel engine, and other tools for Operation of the device. Power and compressed air are passed from this power supply truck 3 via lines not shown on the container car 2 to the front of the spray 1. Electrical energy is u.a. needed to drive the car by means of the 24V traction motors. The secondary drives for the carriage wheels can be, for example, chain drives or toothed belts. With electric motors and the gear pumps are driven on the spray carriage and optionally, the heater on the container car 2 can be an electrical. Further, the control unit 34, which is housed either on the power supply truck 3 or on the spray 1, requires electrical power. This control unit 34 processes the signals of the mass flow meters and all other sensors, such as those for measuring the driving speed and the thermometer on the container car 2. It generates from them control signals for the gear pumps, the pneumatic safety valves at the spray nozzles and The drive motors for driving and for the heating and cooling of the components A, B. Compressed air is needed for the pneumatic safety valves, as well as for vulnerable pneumatic tools on the power supply truck 3. This can namely be configured in a workplace, with a work surface 57 like the a workbench, and with all sorts of tools for any possible service and repair work that might be needed. 6 shows only the switching panel 69 for the operation of the diesel engine and generator and the compressor for the compressed air generation. On the spray carriage 1 is here a control unit 34 with an operating unit, a display unit, a microprocessor control and a plurality of input and output interfaces. The control and power lines between the various components are not explicitly shown in FIG. 6, but these lines are derived from the already described block diagram according to FIG. 5.
    Fig. 7 shows a spray 1 in a view obliquely from behind. Clearly recognizable here are the two electric motors 13, 14 for the gear pumps 11, 12 for precisely metered conveying the two adhesive components A, B, and further you can see the two mass flow meters 15,16. The lever 62 at the rear of the car is used to lift the Sprühwagens 1 so that it can be hoisted from level ground on a lying on this floor rail. If the lever 62 pivoted by hand down, it rotates the pivot wheel 66 and this the load lever 64 in the same direction. This causes the suspension of the Sprühwagens 1 back lifts off on the two support wheels 65 which are connected to a connecting axis 66. At the front of the car one recognizes the boom 18 with the back and forth movable mixer, for example, a spiral mixer 29th
    In Fig. 8, the spray 1 is seen from the front, and here you can see the boom 18 and the back and forth movable spray unit, with which the two supply lines 10,11 via a Y-fitting 26 merged and the components A, B are pumped into a mixer, here in a diaper mixer 29. Below the spiral mixer 29 opens in the not shown spray bar.
    Instead of subdividing the device into three separate cars as just presented, an embodiment with only two cars can be implemented. In this case, for example, the container car 2 and the power supply truck 3 are combined into a single carriage 42 as shown in FIG. 9. Together with a separate Sprühwagen 1 also this composition forms a suitable device when both cars are 1.42 designed about the same weight, to the approximately 500kg. The handling of this device and its two cars 1.42 can be handled by two people. Thus, the device is even more compact and the setup is even faster, because only two cars instead of three must be coupled together on site. Front of this car 42 can be seen the hitch 71 with a coupling ball 72 for this coupling. On this ball 72 can be coupled to the ball socket of a drawbar, the drawbar also has a ball socket at its other ends, for coupling this next car, such as a container wagon or Sprühwagens. The car is equipped with a crane 67 with pulley 68 or electric drive, so that the container 60, 61 heaved with ease from a vehicle in the drip pan 56 and can be used there.
    On the other hand, the composition is also divisible so that the spray 1 at the same time receives the container for the two components A, B, and the second car is solely the power supply, that is, the power generation and compressed air generation and supply, as well as with his work surface 57 serves as a workshop car.
    The division into these either two 1, 42 or three carriages 1, 2 and 3 is the key to the flexibility of the device so that they can be brought to the scene with a road vehicle. Thanks to the division into two or three roughly equal-sized cars, the total weight of the device can be handled by just two people in each case. This means that the device can even be transported on 3.5 tonnes of vehicles on the road and put on the site of only two people on the rails of a railroad track and put into operation.
    For very long to be bonded routes can be a large tanker in the form of a Grachtwagens with a plurality of large container parked on it as the rearmost car follow suit. From this railway car then lead supply lines in the container wagon and its container 60, 61, which then serve as a buffer for preheating the components to the ideal temperature. For such applications, it is advantageous if all two or three cars of the device are designed as self-propelled carriages, so depending on their wheels are driven by electric motors. The speed between the different self-propelled carriages is advantageously synchronized with the speed of the shunting locomotive. The power for this is provided by the 400V generator on the power supply truck 3. With a very large amount of entrained adhesive components on a long freight car, the device may need to be pushed by a separate shunting locomotive. The described speed sensor 43 ensures that the throughput of the two fluid-shaped components is precisely controlled as a function of the respective current speed of the vehicle. Speed changes of a possible additional shunting locomotive can thus be compensated. The spray car with its pumps allows to glue approx. 21 m3 of track ballast per hour. If, for example, 6000 l of adhesive mixture are carried along on the container wagon or along pulled-along railway wagons, the machine can work at full speed for 19 hours, gluing 400 m3 of track ballast perfectly and evenly.
    10 explains how the loading of a road vehicle with the device from here three cars vonstattengeht. Advantageously, a road trailer 48 is used for car transports. Fig. 10 shows such closed with a box road trailer 48 with tandem axle 49, here with open tailgate 59. He is equipped inside with rails 50, of which a part 51 is pulled backwards, or have a swing-out section 51 behind , The rails 51 can therefore be applied beyond the rear edge of the road trailer 48 and the road trailer 48 is tilted backwards, so that one car 1, 2, 3 after another, starting from a flat concrete surface on the rails 50, 51 in the road trailer 48 drivable and afterwards in the road trailer 48 can be pulled. This is best served by an electric cable winch 52 on the front of the trailer 48, as it is otherwise used to charge a car. As shown in Fig. 10 was here first the spray 1 pulled in the road trailer 48, then the container car 2 and finally the power supply truck 3. Thus, the car 1, 2, 3 are loaded in the correct order, as they are needed at the site , After loading the rails 51 are supplied in the road trailer and this is pivoted to the horizontal position. Subsequently, the road trailer 48 can be moved with a tractor 53 to any locations. For this purpose, a 3.5-tonne road vehicle can be used. This has the advantage that this may be driven with a car driver's license and is not subject to any blocking periods, such as a night driving ban or Sunday driving ban, and is not subject to the heavy vehicle charge, as is the case in many trucks. All this provides tremendous flexibility and responsiveness at all hours of the day and night, and the ease of handling of the entire facility is accomplished by just two people. It is no longer necessary a lot of people working.
    Fig. 11 shows an ideal composition of a 3.5 ton road vehicle 53 and an associated road trailer 48 as it is suitable for transporting the entire device on the road. In the road trailer 48, the whole facility can accommodate, whether two or three separate rail cars consisting, and the road vehicle offers 2 to 3 seats, which is enough for a whole work team, because more than two people are not necessary to the facility on site unload and put on the railroad tracks and operate afterwards. Because a road vehicle of the category up to 3.5 tons total weight can be used, there are no restrictions in traffic, for example in comparison to a truck of 7.5 tons or more tons of total weight. Neither is a driving control to lead, nor are there any restrictions because of the weight or width of the road vehicle. For 3.5 tons of vehicles, there are no night driving bans and they can be driven by almost anyone. A spraying crew is not dependent on a person with a truck driver's license. Instead of a towing vehicle can also occur in individual cases, a self-propelled Tieflade vehicle transporter to which the car 1-3 are rechargeable.
    FIG. 12 shows, in a schematic representation with a view from above, how the device is placed on the rails 4 at a place of use. As an ideal location to place the device on the rails 4 of a railroad track, level crossings or wherever the railheads just pass to a concrete slab or asphalt pavement or wood surface prove to be ideal. Here is the situation at a railroad crossing shown. The road vehicle 53 with its road trailer 48 and the device therein comes here from the right approached, then moves as indicated by the arrow on the railroad crossing out and then maneuvered the trailer 48 backwards in the drawn position. The road trailer 48 is then tilted backwards, as already shown for charging the rail cars 1, 2, 3. The three rail cars 1, 2, 3 are visible here on the trailer 48 indicated. Now the rails 51 are extended or swung out in the road trailer to the rear, so that they extend the inner rails 50 in exactly the same direction and are accurately placed with their ends on the railroad tracks 4. Afterwards, with the winch belonging to the road trailer 48, first of all the energy supply car 3 from the road trailer on the rails 50, 51 is allowed to slowly drive backwards until it touches down on the railroad rails 4. The same is done then with the container wagon 2 and finally with the spray carriage 1. Each individual wagon 1,2, 3 is just so heavy that can be easily carried out by two people. One manages the winch, the other monitors the extension and can intervene if necessary. Once all cars 1,2, 3 are on the track 4, they are coupled together with the coupling rods 7, 8 in the form of double drawbars pivotally in all directions. Thereafter, the device is ready to be driven in the image in the upward direction crossing the road and then sprinkle the ballast bed on the desired side.
    In Fig. 13 can be seen the front of the spray carriage 1 in use. At the front of the spray 1 you can see the boom 18 and the spray bar hanging therefrom 17, as well as on both sides of an aperture 47 in the form of a plastic mat, which limits the spray laterally exactly. The spray bar 17 is equipped with a number of nozzles 30 so that different spray patterns of the adhesive mixture can be sprayed. In the picture shown, the sprays are sprayed through a filter 58 which, however, is not necessary in every case. The spray bar 17 may be horizontally displaceable along the boom and also motor-controlled vertically.
    In Fig. 14, a composition of two rail cars is shown, namely a one-piece spray-1 and container car 2 and the power supply truck 3 shown. The view of the front of the sprayer 1 in use shows how the spray bar with its nozzles 30 sprays the adhesive mixture down onto the ballast bed. It can be determined exactly how many grams of adhesive per meter are applied at a given spray width and travel speed, and it can also be determined which spray pattern is most suitable, such as a flat spray curtain or a spray cone, depending on the conditions. On the left and right of the spray bar 17, shutters 47 are mounted, in the form of rubber flaps, so that the spraying area is securely bounded laterally. The control unit 34 of the device ensures that the selected values are maintained constantly and safely. Should any disturbance in the supply of a component A, B occur, this is registered on the basis of the signals of the flow meters and the spraying is stopped immediately by closing the pneumatic valves on the spray nozzles 30. This ensures that never an otherwise highly toxic single component gets into the ground. The spray bar 17 is pivotally mounted about its vertical axis on the boom 18 and extends at an angle to the track 4, but can also be adjusted perpendicular to this. Its height above the ballast bed can also be varied, and it is clear that the spray bar 17 can be moved to any location on the boom 18, depending on where the spray strip is to be laid. In the width shown here outside the one rail of the rail line is expected in most cases with about 15 liters of adhesive mixture per cubic meter to be bonded bulkhead. Of course, the application rate per area or cubature can be varied freely, according to experience and depending on the desired penetration depth of the adhesive into the ballast bed.
    In Fig. 15, one looks at the front of the spray carriage 1, which sprayed here in the left side of the rail track, on which the device is, with adhesive. The controllable and constantly checked driving speed of the two or three carriages of the device guarantees a precisely even application of the adhesive. During the whole operation of the train service can be continued on an adjacent track, as shown in Fig. 15, where just a locomotive passes the facility.
    In Fig. 16, the device is shown in a perspective view with a view of the composition of obliquely behind, with a train passing next to it. At the very back of the power supply truck 3 here a compressed air tank 59 is mounted. This is supplied by the on-board diesel engine and compressor with compressed air and ensures sufficient compressed air supply for tools to be operated and for the pneumatic safety valves at the spray nozzles. Of course, the compressed air tank can also be accommodated in the interior of the energy supply cart 3.
    When applying the two-component adhesive with the inventive device high quality bonds with well-defined width and depth could be made. Investigations of track ballast solidified or glued according to the invention have shown that they hardly contain any imperfections and hold much better than conventionally treated track ballast. This even means that this application method has been certified by the Swiss Federal Railways, and therefore is also recognized by insurance companies, that is, when it is used properly, so that glued paths can be used normally, even if they tucked laterally and never again without gluing would be stable enough for driving on trains.
    Finally, FIG. 17 shows a tracked road vehicle 71, on which all elements for the electrical power supply and control for pumping by means of gear pumps, for the mixing and controlled discharge of the components of a multi-component adhesive over a front mounted spray bar 17 are present. All elements, components, components, etc. described above are combined on this vehicle 71, including the diesel generator for power generation, the compressor with pressure vessel for a supply of about 30 liters of compressed air for the operation of the entrained pneumatic tools and the pneumatic safety valves at the spray nozzles. A heater for preheating the components to the ideal temperature is also included. With this vehicle 71 can be driven anywhere on a rail track somewhere. Then, the rail wheels 72 are hydraulically lowered and locked, after which the vehicle 71 drives with its Pneurädern 73 on the rails and is guided by the rail wheels 72 on the same. In front of the vehicle 71, the boom 18 and the spray bar 17 is mounted on site and the flexible hoses are connected. Everything else works essentially the same as with a two-part or three-part composition as described in detail earlier. The components A, B may be carried directly on this vehicle 71, or larger quantities of adhesive components may be carried in separate containers, for example on a railway goods wagon, by attaching this wagon to the rail road vehicle 71 and by means of the flexible hoses The components are pumped out of these containers on this railway freight car and sprayed after mixing. Thus, the capacity is greatly expandable. Mile-long distances can be handled very quickly by only two people as operators, but it is ensured that the application takes place in perfect mixture and perfect uniformity. For example, if you carry 6000 liters of adhesive on a pulled-along rail car, 400 m3 of track ballast can be bonded in one operation, which can be done in less than 20 hours. For such a quantity one needs today with the usual manual spreading alone locally at least 100 hours, which means in the reality approx. 2 working weeks, without the entrainment and transporting of comparatively small batches of components into account. And yet it is not guaranteed that the bonding is carried out so evenly that the track can be certified afterwards for driving and therefore no breaking in of the route under heavy load must be feared.
    In summary, it should be noted that this device for discharging a multi-component adhesive over the conventional application by hand, in particular in the bonding or solidification of gravel in railway systems brings enormous benefits. In particular, it can be used extremely flexibly by being easily transportable on the road in situ, can be placed there by only two people on the rail, and afterwards allows them to increase the rate of application of the multi-component adhesive massively and the quality of bonding of Track ballast to improve greatly.
