专利说明:

The invention relates to a track safety device for a track barrier for securing or delimiting a section of a track rail, in particular a railway line, with a bar holder for at least one barrier bar of the track barrier, in particular for two barrier bars, and with a device carrier for the detachable attachment of the track safety device a rail foot of the track rail, with a hook being provided at the outer end of the device carrier, which can be brought to one side of the rail foot and clamped there against the rail foot, the device carrier having a fastening rod and a slide that can be displaced longitudinally on the fastening rod with one the other side of the rail foot having cross-movable clamp with the slider, wherein a clamping lever is provided as a locking means to lock the slider in a clamping position, wherein the hook on a on or in the mounting rod longitudinally displaceable hook tube of the device carrier is provided and wherein the hook tube is spring-loaded via a spring means and is pulled by the spring force of the spring means in the direction of the slide.
The present invention also relates to a barrier for a track safety device of the aforementioned type.
Track safety devices of the type in question are known, for example, from EP 2 806 064 B1. The disclosure content of EP 2 806 064 B1 is fully included in the disclosure content of the present description.
[0004]Regarding the functioning of the known track safety device, reference is also made to the disclosure content of EP 2 806 064 B1.
The track safety device known from EP 2 806 064 B1 has proven itself in operation. Compared to other known track safety devices, the safety device can be assembled and disassembled more easily and quickly, with a very secure connection to the track rail being ensured even when the track is heavily loaded by passing trains. In addition, the known device has high component stability and can be manufactured inexpensively. Finally, the known track safety device can be easily attached to track rails of different sizes and standardized in the same way.
[0006] Nevertheless, the components of the track safety device known from EP 2 806 064 B1 are subject to high stresses due to corrosion, friction and impact loads during assembly, transport and storage, in particular when the clamping mechanism is relieved.
The object of the present invention is to further develop the track safety device known from EP 2 806 064 B1 and to provide a track safety device with further improved features and properties, in particular improved corrosion resistance and higher (wear) strength, wherein the assembly and disassembly of the track safety device are possible in an even simpler manner without impeding the work flow and with even less expenditure of time. Furthermore, an improved barrier bar for use with a track safety device is to be made available.
The aforementioned objects are each achieved by a track safety device with the features of claims 1, 4, 8 and 9 and by a barrier according to claim 10. Advantageous embodiments of the invention are the subject of the dependent claims.
According to a first aspect of the invention, it is provided that the basic construction of the spar holder and the device carrier is made of structural steel, in particular an unalloyed structural steel, more particularly of the type S235JR (material number 1.0038) or of the type S235JRC (material number 1.0122), S235J2 (material number 1.0117) or S235J2C (material number 1.0119), or consists of an aluminum material or an aluminum alloy or of a chromium-nickel steel, for example X5CrNi 18-10 (material number 1.4301), or consists predominantly If structural steel is chosen for the basic construction, it is marked Compared to other materials, this is characterized by high strength and a low carbon content and thus high deformability. The carbon content can be less than 0.20%, for example 0.17%. A further advantage of construction steel is the good suitability of this material for welding, whereby all components of the track safety device according to the invention, with the exception of the barrier bars, can be welded constructions. Manual metal active gas welding (MAG) can be used to produce the welded joints. Last but not least, the good availability and low material costs of this material are advantageous. In contrast to mild steel, aluminum materials (austenitic) chromium-nickel steels are characterized by lower weight and higher corrosion resistance. The disadvantages of aluminum materials and chromium-nickel steels are higher material costs and a higher risk of theft when used outdoors.
The basic design of the track safety device according to the invention can correspond to the design of the track safety device known from EP 2 806 064 B1. The device carrier can in particular include the fastening rod, the slide, a multi-part clamping lever, as described in EP 2 806 064 B1, and the hook tube with the hook. On the other hand, connecting and/or joint elements, such as nuts and threaded pins, in particular, are made of other materials, which can be made, for example, of stainless chromium-nickel steels such as X5CrNi 18-10 (material number 1.4301).
Active and/or passive measures can be used to protect against corrosion. According to the invention, an example of active corrosion protection is a suitable choice of material for connecting and joint elements, such as nuts and threaded pins, which can be made of stainless chromium-nickel steels, in particular X5CrNi 18-10 (material number 1.4301). A use of this material for the production of the basic construction of the bar holder and the device carrier is preferably not intended due to the high material costs, but is not ruled out in principle.
According to the invention, however, passive anti-corrosion measures are preferably taken, with the components of the basic construction of the spar holder and the device carrier being able to have a coating, in particular a metallic coating, in which case, preferably, all welded constructions can be hot-dip galvanized and/or electrogalvanised and, more particularly, yellow passivated . Compared to blue passivation, galvanizing and subsequent yellow passivation has the advantage that the corrosion protection can have a higher rust resistance. For example, yellow passivation according to DIN 50979 can take place. The corrosion protection can be further increased by an additional sealing.
[0013] In the case of galvanizing, a thin protective layer is achieved to improve protection against corrosion. The advantages of this process include the fact that it is free from thermal stress and is characterized by a high level of protection against corrosion. Uniform layer thicknesses of between 5 and 20 µm, for example, are achieved here, which allows close tolerances to be maintained, eliminating the need for post-processing. Last but not least, the process can be carried out very economically. According to the invention, however, a coating of all components, with the exception of the connecting and/or articulated elements, by hot-dip galvanizing is preferably proposed as a corrosion protection measure. Dipping into molten zinc causes the formation of a stable and resistant passive layer on steel parts, which leads to high corrosive resistance. A relatively thick layer of the metallic coating of more than 20 μm, in particular between 50 and 150 μm, protects the treated components of the basic structure from mechanical stress, such as abrasion. This is advantageous because of the fretting wear or fretting corrosion that occurs during operation. Zinc tips that occur during the galvanizing process can be removed by reworking the components after hot-dip galvanizing.
Another aspect of the present invention relates to reducing the consequences of mechanical stress on the track safety device during operational use, in particular increasing the strength of the components.
During assembly and operation, the track safety device according to the invention does not experience any significant external stress from train, pressure or bending. Due to the preferably provided support of the spar holder on a base, the spar holder and the device carrier are relieved with regard to forces that result from the weight of the installed barrier. However, a critical load situation arises in particular during disassembly. At the moment the clamping lever is unlocked, the fastening rod, triggered by the spring force of the spring means, is accelerated in the direction of the hook. After a spring distance has been covered, the fastening rod suddenly hits the hook. In order to prevent crack formation on the device carrier, in particular on the fastening rod, in particular due to force impact when unlocking the slide by actuating the clamping lever due to a relative movement of fastening rod and hook tube, at least one constructive means for preventing cracks is proposed according to the invention.
The constructive means can in particular be designed to dampen the spring force of the spring means, further in particular by using a damping cylinder and/or a gas pressure spring with a damping mechanism. When using a spring with return damping, when the clamping lever is relieved, the device carrier accelerated by the spring force or the fastening rod is braked by a damping cylinder, for example a gas spring. This method relieves the load on the frame end of the device carrier, i.e. in particular the end of the fastening rod.
An alternative solution provides that a locking device is provided to form a form fit between the hook tube and the fastening rod in the unlocked position of the slide, the hook with the locking device being kept at a distance from the free end of the fastening rod in the unlocked position of the slide .
A preferred embodiment of the invention provides that at the free end of the fastening rod there is a locking means, for example a locking bolt or a locking nut arranged transversely to the longitudinal direction of the fastening rod and penetrating the fastening rod, and that the hooked tube can be longitudinally displaced to the locking means via a slot guide or is guided in the fastening bar, with the hooked tube resting against the blocking means in the unlocked position of the slide when the elongated hole guide reaches an end position and the hook is held at a distance from the free end of the fastening bar by the blocking means. The locking device actively prevents contact between the hook and the frame end of the device carrier. For example, a screw that is guided through the fastening rod and the slot guide in the hook tube can be provided, with the hook tube remaining movable in the axial direction via the slot guide and being able to be braced on the rail profile. In the resting position, the hook tube then rests on the screw tightened on the device carrier. The stress of the frame termination of the device carrier is completely transferred to the lock. A burst of force when unlocking the slider is directed from the semicircles of the elongated holes via the screw into the frame end. A form fit can be achieved by a symmetrical arrangement and an appropriate choice of fits. The shear stress and notch effect are very low.
In an alternative embodiment of the invention, a reduction in the spring force of the spring means with which the hook tube is held on the device carrier under tension is provided to prevent cracks. The invention provides for needs-based adjustment of the clamping force of the rail clamp. A reduction in the spring force of the spring means, which connects the hook tube or hook and device carrier or fastening rod, leads to a reduced force impact when the slide is relieved and thus to a lower load on the frame closure when the track safety device is unlocked. However, the prerequisite is that the rail clamp can nevertheless be firmly clamped to the track. By reducing the spring force, the frame end is less stressed and the risk of cracking is significantly reduced.
The spring force of the spring means can be more than 200 N, preferably more than 300 N, and/or less than 500 N, preferably less than 400 N, based on a locking state of the device carrier on the foot of the rail, i.e. when the slide is arranged in the clamping position N, more preferably less than 350N. In particular, the aforementioned spring forces relate to a maximum rail foot width of preferably between 100 and 200 mm, more preferably between 125 and 150 mm, which corresponds to the standard rail profiles S 49/S 54 (rail foot width: 125 mm) and UIC 60 (rail foot width: 150 mm ) is equivalent to. In the locked state, the spring deflection of the spring means can preferably be between 50 and 100 mm, more preferably between 65 and 80 mm.
The clamping effect of the rail clamp can particularly preferably be applied by a cylindrical helical tension spring, which can be connected to the device carrier via an internal sliding fit.
The spring can be prestressed and have a specific prestressing force when the spring deflection is zero. The wound prestressing force of a helical spring can be less than 100 N, preferably between 50 and 75 N, for example approximately 70 N.
The structural design of the track safety device according to the invention can preferably provide that the spring is already in the non-clamping state of the slide, when the track safety device is not yet mounted on the track rail and the hook due to the tension force of the spring against the frame end of the device carrier or against the free end of the fastening rod is in contact, is stretched out. A high clamping force can be achieved even in the non-clamping state. In the non-clamping state, the spring force can preferably be less than 300 N, more preferably 250 N or less. The spring deflection in the non-clamping state can preferably be between 30 and 60 mm, in particular between 40 and 50 mm, more particularly approximately 45 mm.
Another aspect of the present invention enables improved handling of the track safety device according to the invention during assembly and disassembly. As described in EP 2 806 064 B1, the rail holder of the track safety device according to the invention can have a rail holding rod and/or a rail fastening rod, the rail holding rod being displaceably connectable to a support rod for support on a substrate and/or the rail fastening rod being displaceably connectable to the device carrier By shifting the handlebar holding rod relative to the support rod, the ground clearance of the handlebar holder can be adjusted and changed; the distance between the rail holder and the track can be adjusted and changed by moving the rail fastening rod relative to the device carrier. A set distance can be fixed using at least one safety element, such as a safety cotter pin, more particularly a spring pin, which is inserted into a safety point, for example designed as overlapping bores in the handlebar holding rod and the support rod or in the handlebar fastening rod and a holding rod of the device carrier According to the invention, it is provided that the securing element is held in the securing point with a minimum play, based on a centered state, of at least 0.5 mm, preferably at least 0.8 mm. The minimum play is preferably 1.0 mm or more . As a result, safety elements can be positively connected to the rail holder and/or the device carrier with little effort, which simplifies handling during assembly and disassembly of the track safety device according to the invention. If, for example, spring pins are provided as securing elements, they can be inserted and pulled out more easily through corresponding adjustment bores in the spar holder and/or device carrier.
Finally, the invention relates to a barrier for a track safety device of the type according to the invention, wherein the barrier is designed as a hollow profile made of glass fiber reinforced plastic and the wall thickness of the hollow profile is less than 4 mm, preferably 3 mm or less, due to the wall thickness provided according to the invention there is a weight saving of the barrier bars, the manual transport of which, according to the subjective reports of the assembly personnel, represents a greater burden on the body than the transport of the components of the basic construction of the bar holder and the device carrier. Since the track barriers often extend over several 100 m, numerous manual transports are necessary to bring the barrier bars to a desired destination. The weight reduction is advantageous for both manual transport and truck transport.
Further advantages and advantageous configurations of the invention can be found in the following example description, the drawing and the claims.
An embodiment of the invention is shown in the drawing and is described in more detail below. The drawing shows Fig. 1 a side view of a track safety device according to the invention with a bar holder for two barrier bars (not shown) of a track barrier and with a device carrier for fastening the track safety device to a track rail, with different distances between the bar holder and the center of the track or the rail foot being shown, Fig. 2 shows an enlarged representation of a device carrier mounted on a track rail of the track safety device shown in FIG. 1 from the side, and FIG. 3 shows a schematic representation of a track barrier with two track safety devices and two barrier bars.
In the figures, a track safety device 1 for a track barrier 2 shown in FIG. The structural design of the track safety device 1 described below essentially corresponds to the structural design of the track safety device known from EP 2 806 064 B1. The disclosure content of EP 2 806 064 B1 in relation to the description of the figures is fully included in the disclosure content of the following description of the figures.
The track safety device 1 has a bar holder 4 for fastening two barrier bars 5 of the track barrier 2 . In addition to the rail holder 4, the track safety device 1 comprises a device carrier 7, which has a fastening rod 8 for the detachable fastening of the track safety device 1 to a rail base 6 of the track rail 3 end facing the rail foot 6 on this side has a movable clamp 10 with the slider 9 . In order to clamp the track safety device 1 to the rail foot 6, the clamp 10 interacts with a hook 11 on the rail-side end of the device carrier 7, which can be moved to the other side of the rail foot 6 and there engages over the rail foot 6. In order to keep the slide 9 in a clamping position, a multi-part clamping lever 12 is provided as a locking means.
In the embodiment shown, the clamping lever 12 has two lever arms 13, 14 of equal length, with the lever 13 facing away from the rail foot 6 at its end in a horizontal axis 15 on the fastening rod 8 and the lever arm 14 facing the rail foot 6 at its end the end facing the rail foot 6 is articulated in a horizontal axis 16 on the slide 9 . Between the ends of the lever arms 13, 14, the clamping lever 12 has an articulated joint 17 which, when the slide 9 is closed or if the slide 9 is locked in the clamping position, rests slightly vertically below the axes 15, 16 on the slide 9 and is located above these axes 15, 16 when the slide 9 is open. The locking of the slide 9 in a clamping position thus takes place according to the toggle lever principle, a dead center of the clamping lever 12 being exceeded in order to lock the slide 9 . If the slider is locked in the clamping position, the articulated joint 17 assumes a position in this state from which it cannot move into the open position as a result of horizontal force effects. Figures 1 and 2 show the track safety device 1 in the locked state of the slider 9. It goes without saying that a different length of the lever arms 13, 14 and/or the arrangement of the axes 15, 16 and the articulated joint 17 relative to one another and can be provided relative to the fastening rod 8 or the slide 9.
In order to enable the device carrier 7 to be clamped to track rails 3 with different rail foot widths, a hook tube 18 that can be displaced longitudinally in the fastening rod 8 is provided. At the free end of the hook tube 18, the hook 11 is rigidly attached. The hook tube 18 is pulled towards the slider 9 by the spring force of a tension spring 19 . This enables the device carrier 7 to be clamped to a track rail 3 in a simple and functionally extremely reliable manner. Due to the spring force of the tension spring 19, a maximum of security against loosening the connection between the device carrier 7 and the track rail 3 is achieved. The tension spring 19 is fixed at one end to the attachment rod 8 and at the other end to the hook tube 18 . The tension spring 19 is arranged inside the attachment rod 8 .
In the embodiment shown, the tension spring 19 preferably has a spring force of less than 400 N, more preferably less than 350 N, based on a locking state of the device carrier 7 . In this case, the spring force is dependent on the spring deflection, which depends on the width of the rail foot 6 .
In addition, the basic construction of the spar holder 4 and the basic construction of the device carrier 7 is preferably made of unalloyed structural steel, more preferably of the S235JR type (material no. 1.0038). The basic constructions of the spar holder 4 and the device carrier 7 have a metallic coating as passive protection against corrosion, which can be obtained by hot-dip galvanizing. The metallic coating can have a layer thickness in particular in the range between 50 and 150 μm.
For fastening the lever arms 13, 14 of the clamping lever 12 to the fastening rod 8 or the slide 9, bolts 20 can be provided. In order to be able to actuate the clamping lever 12 , a round steel part 21 is provided that forms the articulated joint 17 .
The spar holder 4 has a vertical support rod 22 and a horizontal spar fastening rod 23 . The spar fastening rod 23 can be pushed into a holding rod 24 of the device carrier 7 . By telescopically connecting the rail holder 4 to the device carrier 7, the distance between the vertical rail holding rod 22 and the track can be varied. Bores 25 are provided in the spar fastening rod 23 and in the holding rod 24 for locking purposes, it being possible for the locking to be effected by inserting spring pins into mutually overlapping bores 25 .
To support the track safety device 1 on a floor, a support rod 31 is provided with a rubber foot 27, which can be inserted from below into the spar holding rod 22 and moved telescopically. The locking takes place via overlapping bores 26 in the support rod 31 and the spar holding rod 22 by means of securing elements such as spring pins.
In the track safety device known from EP 2 806 064 B1, a load peak occurs when the hook 11 comes into direct contact with the free end of the fastening rod 8 when the clamping lever 12 is unlocked. This can result in an upper sheet metal of the fastening rod 8 being peeled off after the track safety device has been used for a long time. Crack damage in the area of the frame closure can make assembly of the track safety device 1 more difficult. The elimination of crack damage is associated with an unwanted repair effort.
As can be seen from Fig. 2, a blocking means 29 is therefore provided at the free end of the fastening rod 8, with the hook tube 18 resting against the blocking means 29 in the unlocked position of the slide 9 (not shown) and the hook 11 via the blocking means 29 from the free end of the mounting rod 8 is kept at a distance. In the embodiment shown, the hook tube 18 has a slot 28 . A screw is guided through the slot 28 and the fastening rod 8 as a locking means 29 transversely to the longitudinal direction of the hook tube 18. The hook tube 18 can be moved in the axial direction via the slot 28 and can be clamped with different distances between the hook 11 and the clamp 10. This is shown schematically in FIG. 2 by the distance a by which the hook tube 18 can move due to the tensile force of the tension spring 19 to the left in relation to the position shown in FIG. 2 into the unlocked state or idle state. At rest, the hook 11 is held at the end of the hook tube 18 at a distance from the free end of the fastening rod 8 . This prevents the hook 11 from being able to come into direct contact with the free end of the fastening rod 8 when the clamping lever 12 is unlocked, so that cracking in the area of the frame end is prevented.
