    [001] The present invention relates to an automatic road mill to operate road surfaces, especially a large mill, according to the preamble of claim 1, that is, it encompasses a process to operate road surfaces according to the preamble of claim 14.
    [002] As large milling cutters are generally referred to as road milling cutters with a milling width of about 1500 mm and above. These road milling machines have a very high weight and, therefore, will normally be supported by a displacement mechanism with chain displacement mechanisms. The milling roller is mounted on the machine frame between the chain displacement mechanisms and the front and rear axles and this is spaced from these units. Large milling cutters have a height-adjustable travel mechanism with front and rear travel mechanisms in the direction of travel that form the front axle, ie the rear axle. The machine frame is supported by a displacement mechanism, and between the axes of the front and rear displacement mechanisms, a holding roller housing is arranged on the machine frame, which features a single rotating cutter roller inside the housing. of the cutter roll. The milling roller housing, with the aid of a track shoe, the conveyor belt assembly for removing the milled material, already worked by the milling roller and ejected, being coupled in the direction of travel, in the forward direction.
    [003] A large milling cutter of this kind is, for example, known from the European patent EP 2 011 921 A.
    [004] The milling roller housing is joined with a front side almost at the top with an external side of the machine frame, the so-called zero side, in order to allow a milling as close as possible along the edges or obstacles. The cutter roll housing cannot be height-adjusted in relation to the machine frame, so that the full weight of the machine can be transferred to the cutter roll, in order to enable intense cutting forces and, therefore, a high depth of the milling itself.
    [005] Among other aspects, large milling cutters, considering their restricted maneuverability, have so far been used mainly only to work in large areas, and correspondingly to the layout of the road, it was also possible to work curves of the road, with large radius of curve.
    [006] Especially, when milling works that, relative to the zero side, lead inwards, in large cutters there is a problem that the driver of the vehicle cannot exactly follow a predetermined curve line with a very radius of curve narrow. For this purpose, from EP 2 011 921 a solution can be understood, for which a visual control for the direction of a large mill was made possible, with which the possibility of maneuvering a large mill can be improved.
    [007] On highways with traffic on the right, the zero side of a road is preferably arranged on the right side of the machine, in the direction of travel. On highways with traffic on the left side, the zero side is preferably on the left side (in the direction of travel). It is understood that a large milling cutter, when there is enough space for an inversion maneuver, can also be inverted and, therefore, also a large milling cutter with the zero side can be used on the right side in the direction of travel for highways with traffic on the left side. This presents the disadvantage that the road mill, which has its zero side on the right side in the direction of travel, will have to move in the opposite direction of the traffic flow when a highway, during operation, cannot be completely closed. A situation of this kind appears, for example, when on a highway the left vestige should be milled at the top with the left side of the highway. In this case, it is a disadvantage that the trucks that collect the milled material, in front of the road mill, need to move in the opposite direction to the flow of traffic in front of the road mill and from there, they need to move away again. But also in the case of narrow highways, there is often a desire to be able to work in line with the highway, selectively on the left or right side, without having to invert the large milling cutter.
    [008] In this case, for example, in document DE83 15 139 U, on a road mill, supported by a wheel mechanism, they move a single hydraulic milling cutter roller transverse to the direction of travel, when along sliding guides and on a reduced stroke. It is not a large cutter with which intense cutting forces can be used, because the cutter roller is rotatable around a horizontal axis and rests on the ground only by its specific weight. Therefore, the milling roller, relative to the machine frame, can be suspended or lowered and additionally can be rotated on an axis that extends in the direction of travel, in order to adapt to the slope of the road. The possibility of transverse displacement should allow an exact control of the milling cutter. It is understood that due to this pendulum assembly of the cutter roller, intense cutting forces cannot be applied to a cutter of this type, only suitable for surface milling, without great depth of cutter.
    [009] The objective of the present invention is to create an automatic road milling machine of the initially mentioned species, as well as a process for working road surfaces that can be used universally and whose maneuverability is improved.
    [0010] To solve this task, the characteristics of claims 1 to 14 apply.
    [0011] The invention advantageously provides that the milling roller driver is a hydraulic or electric drive, integrated in the milling roller itself and that the milling roller, together with the milling roller housing and the milling roller driver is mounted displaceable transversely to the direction of travel in the machine frame, with which, selectively, the zero side can be fixed. On an external side or on the opposite external side of the machine frame.
    [0012] The solution recommended by the invention has the advantage that essentially the entire weight of the machine, due to the arrangement of the milling roller between the axes of the displacement mechanism, acts on the milling roller, with which great depths are viable with high feed speeds. Due to the feasibility of moving the milling roller, the zero side can be selectively fixed on one external side or on the other external side, so that with the preservation of the direction of travel, the left or right side can be selectively worked at the top and over obstacles. In this case, the milling roller can also be moved during the milling operation, for which the milling roller preferably has additional chisel tools on its front edges. The milling roller will be moved together with the milling roller housing and the milling roller housing integrated in the milling roller, in a linear and transverse direction to the direction of travel, in the machine frame. The linear guide, below the machine frame, has the advantage that neither the milling depth nor the transverse inclination of the milling roller are influenced by the linear displacement. This is important when leveling the road mill with the aid of the adjustable height displacement mechanism. An essential advantage lies in the fact that only the position of the machine frame needs to be controlled in order to be able to carry out any corrections. Another advantage is that during the operation the milling roller can be moved, without the need for service interruption.
    [0013] The milling depth can be adjusted using the adjustable height displacement mechanism. The high pressure requirement of the cutter roll, through the machine frame, in connection with the cutter roll housing, allows for minimum cutter depths of 30 cm, so that in a single passage the entire road layer can be removed.
    [0014] The change in the concept of conventional mechanical drive with a belt drive and the integration, preferably of two motors in the cutter roller, make it possible to vary the position of the cutter roller in a transversal direction towards the direction of travel.
    [0015] Preferably, the cutter roller actuator takes place on both sides, that is, with two sets of actuators, integrated on the front sides of the cutter roll.
    [0016] Preferably, it is foreseen that the linear displacement of the milling roller takes place along two linear guides, spaced in the direction of the machine frame displacement.
    [0017] The two linear guides produce a rigid molding of the milling roller housing in the machine frame and, therefore, also a rigid assembly of the milling roller in a vertical direction, so that precise adjustment of the milling depth remains preserved . In addition, the assembly of the cutter roller housing in the direction of travel is rigid, so that the mobility of the cutter roller only exists in the transverse direction to the direction of travel.
    [0018] A first of the linear guides is a tubular line that forms a fixed support and a second of the linear guides is a guide between flat surfaces and forms a movable support.
    [0019] Consequently, the support for the milling roller housing has a fixed support and a movable bearing, and the gap between the flat surfaces of the movable bearing can be readjustable.
    [0020] Preferably it will be provided that the linear guides are attached below the frame of the machine, in this frame of the machine.
    [0021] The layout of the linear guides below the machine frame has the advantage that the force of the machine's weight can be transferred immediately through the fre- quency roller housing to the milling roller and the guides can be economically arranged of space.
    [0022] The milling roller housing is attached in the direction of lifting and in the elevation of the displacement in rigid form in the machine frame.
    [0023] On the front sides, the milling roller housing has a height-adjustable side plate. The circle of the cut on the front sides of the milling roll, in the process of milling along an obstacle, for example, a post or a column of a bridge, preferably will have a distance from the obstacle, less than 120 mm, preferably 105 mm or less than 105 mm.
    [0024] The vestige of maximum lateral displacement of the milling roller located between 500 and 1000 mm. This displacement trace makes it possible to selectively fix the zero side on the left side on the right side of the road mill.
    [0025] Preferably, the cutter can be hydraulically driven on both sides. The bilateral actuator has the advantage that the torsional load of the cutter roll can be reduced and ultimately a greater potential can be transferred to the cutter roll. Alternatively, an electric actuator is possible.
    [0026] In the cutter roller housing, a height-adjustable track shoe may be provided to receive the lower end of the conveyor belt assembly. The track shoe can follow the movement of the cutter roller housing in a transverse direction to the direction of travel, so that the lower end of the conveyor belt assembly is always arranged in the ejection opening of the milled material, close to the milling roll.
    [0027] For this purpose, it is provided that the conveyor belt assembly is articulated together with the conveyor shoe.
    [0028] For the articulated reception of the lower end of the conveyor belt assembly, the conveyor shoe has an insertion trough, essentially concave, preferably spherical, which cooperates with a lower side of the lower end of the conveyor belt assembly, suitable for the insert trough format.
    [0029] The front end of the conveyor belt assembly in the machine frame is longitudinally displaceable along the longitudinal axis of the conveyor belt assembly and is mounted by card.
    [0030] At the front end, the conveyor assembly can be rotated around an elevated vertical axis - in the case of horizontal alignment of the machine frame - as well as in relation to a transverse axis that extends in parallel to the axis of the cutter roll.
    [0031] For mobile assembly, the conveyor belt assembly has at least at the front end a support element with a support surface, preferably convex, provided essentially in the longitudinal direction of the conveyor belt assembly, being provided beside the conveyor belt , this supporting element being laterally driven. It rests on a support element, preferably with a convex support surface, fixed transversely to the direction of travel in the machine frame. The rest surface and support surfaces form a card-like joint, with the added advantage that reduced rolling around the longitudinal axis of the conveyor assembly is also possible.
    [0032] The support element on the side of the conveyor belt and / or the support element on the side of the frame, can be formed of a profile or a hollow profile with a rounded cross section. These can advantageously be superimposed, thus enabling a point-like assembly that allows the entire conveyor belt to be moved along its longitudinal axis.
    [0033] Preferably, on a synchronous running guide, the track foot is height adjustable. In this case, the conduction of the track shoe to suspend and lower is similar to a linear conduction, in which the height adjustment takes place in synchronism on the right side and on the left side of the track shoe, to the same extent.
    [0034] In the milling roller housing, a hydraulic angle distributor may be fixed for supplying the hydraulic actuators, provided in the milling roller housing, with at least one milling roller driver being provided there.
    [0035] The hydraulic angle distributor, fixedly arranged in the hobbing roller housing, allows the hydraulic lines in the hobbing roller housing, in relation to the actuators, to be rigidly formed, avoiding too narrow radii of curvature of the supply lines on the part of the supply lines of the hydraulic pumps.
    [0036] In order to improve the maneuverability and the universal applicability of a large milling cutter, it can also be provided that the rear end in the direction of travel of the milling roll housing closes the end with a height-adjustable scraping plate, which slopes laterally on the milled cutter end of the milling roll in an elastic way against the milled edges of the cutter end orthogonally towards the road surface.
    [0037] Due to the fact that the scraping plate may loosen laterally, the large cutter can move in narrow radii of curves, without causing the scraping plate to bend. Another advantage is that the scraping plate, by means of the elastic backrest of the scraping plate against the cutter edge of the milling cutter, can remove the milling cutter without residues of milled material.
    [0038] In this case, the rear end - in the direction of travel - of the milling roller housing may close at the top with a height-adjustable scraping plate that at the two side ends has a movable plate element that essentially closes at the bottom edge at the top with the scraping plate, with which it can be jointly adjusted in height, the plate elements, in parallel with the scraping plate and the milling roller axis, are adjustable against a molar prestressing for the dynamic adjustment of the scraping plate width during the milling process.
    [0039] In a shift to work road surfaces, with an automatic road milling machine, with a machine frame with external side sides, with a single rotatable mounted milling roller, and with a milling roller driver for this milling roller, in which the milling roller closes the end with a front side with the external side of the machine frame, the so-called zero side, in order to enable the closest possible milling, along edges or obstacles, it is provided that selectively the zero side is fixed on an external side, or on the opposite external side of the machine frame, the milling roller driver being integrated into the milling roller as a hydraulic or electric actuator, and the milling roller is movable together with the cutter roller actuator transverse to the direction of travel.
    [0040] In the following, with reference to the drawings, an example of carrying out the invention will be explained in more detail.
    [0041] The figures show:
    [0042] Figure 1 is a partial schematic view of the automatic road mill,
    [0043] Figure 2 the cutter roller housing as a movable module,
    [0044] Figure 3 the cutter roller housing with a set of conveyor belt, articulated coupled,
    [0045] Figure 4 the cutter roller housing, in rear view with the scraping plate, and
    [0046] Figure 5 is a perspective view of the combination of the milling roller housing and the attached conveyor assembly, seen from below.
    [0047] Figure 1 shows a road cutter 1, especially a large cutter, or a machine frame 8 and a displacement mechanism 4 with displacement mechanisms 5, 6 front and rear in the direction of displacement 31. The mechanisms furniture 5, 6 form a steerable front axle and a steerable rear axle. The displacement mechanism 4 is connected through the displacement columns 7 with the machine frame 8, with the help of which the distance from the machine frame 8 to a road surface can be adjusted 2. Each axis of the displacement mechanism has at least one movable mechanism chain 5, 6 or a mobile wheel mechanism.
    [0048] At the front end - in the direction of travel - of the road mill 1 is a set of conveyor belt 18, rotatable in height and to the sides, for the removal of the incident milled material.
    [0049] The mechanisms, movable front and rear 5, 6 of the displacement mechanism 4, can consist of movable mechanisms of chains or wheels.
    [0050] Essentially, the frame of the machine 8 has external outer sides 26, 28 that essentially extend in a vertical and parallel direction with the longitudinal central axis of the road mill 1. It is understood that the external sides 26, 28 do not need to extend absolutely vertically and absolutely parallel to the longitudinal central axis of the road mill 1, however, small deviations are possible. The outer side 26, 28 is preferably produced in one piece, the outer sides 26 and 28 being preferably positioned in a plane.
    [0051] Between the movable mechanisms 5, 6 there is arranged a defrost roller 12 which is mounted with its milling roller axis in a housing of the milling roller 10.
    [0052] The milling roller 12 approaches with an external side 22 front side 26, 28 shown in figure 1 as the zero side, of the machine frame 8. On the external side, zero side is the front side 22, corresponding of the cutter roll, very close to the outside of the road cutter, so that the milling can be done very narrowly at the edges of the roads or in obstacles.
    [0053] Preferably on both sides of the cutter roll 12, front end 22, integrated hydraulic or electric cutter rollers 14 are supplied by hydraulic pumps or generators, arranged in the frame of the machine 8 and which in turn are activated by a combustion engine 3, which provides the necessary drive energy for displacement, for milling work and for supporting sets.
    [0054] On the front sides 22 of the cutter roll 12 and next to the cutter roll housing 10, a side plate 15 of adjustable height is provided that serves as edge protection.
    [0055] Seen in the direction of travel 31, the milling roll 12 is preferably arranged in the center between the front movable mechanism 5 and the rear movable mechanism 6.
    [0056] The cutter roll 12 is equipped with tools 13. The cutter roll 12 rotates in a view on the right side of figure 2, clockwise.
    [0057] The single milling roll 12 can also be made up of several components or, for example, it can consist of at least one laminated tube, fitted over the basic body. In the same way, the milling roller can also be made up of several segments.
    [0058] Above the cutter roll 12 there is a platform commanding 16 that can have two seats 20 with two sets of direction 24 that are provided for milling on the left side and on the right side, along a highway. It is understood that it can also be used on a displacement control platform, transversely to the direction of travel, having a seat and a set of steering 24 belonging, which, according to the need, can be moved to the side left or right side of the road milling machine 1.
    [0059] Preferably the seat 20 is aligned in such a way with the external side wall 26, 28 that the seat 20 goes at least partially and on the side, in the opposite position to the external wall 26, 28.
    [0060] If the road mill 1 with a zero side is moved along an obstacle, for example, on a lamppost, the control platform 16 with the seat 20, the arm support and the control platform 25 can be moved inward to allow a closer and top milling in relation to the obstacle.
    [0061] The external side 26, 28 presents a recess 32 in front of the platform 16. This recess 32 allows the observation of the front mobile mechanism 5 and, therefore, the observation of the momentary action of the steering.
    [0062] Figure 1 shows the cutter roller housing 10 with a scraper plate 64, and the side plate 15 is also suspended to show the position of the cutter roller 12. The cutter roller housing 10 is mounted displaceable in linear and transverse direction to the direction of travel 31 in the machine frame 8, with which the zero side can be selectively fixed on an external side 26, 28 or on the opposite external side of the machine frame 8.
    [0063] The displacement of the cutter roller housing 10 takes place with the aid of two guides 34, 36, spaced in the direction of displacement of the machine frame 8, being formed as linear guides.
    [0064] The first linear guide 34 is a tubular guide which in figures 2 to 4 is arranged on the upper side in the roller housing the mill 10.
    [0065] The second linear guide 36, with distance, is also arranged on the upper side of the milling roller housing 10. The linear guidance takes place between the flat surfaces 37, 38 as best seen in figures 2 and 3. The flat surface 37 is provided both on the upper side and also on the lower side of a beam 39 which is fixedly fixed with a flange component 41 on the lower side of the machine frame 8, The flat surfaces 37 are surrounded by guide components 43, fixedly connected with the milling roller housing 10, which have flat surfaces 38 which are in contact with the flat surfaces 37 of said beam 39. The distance from the flat surfaces 38 which are in contact with the respective flat surfaces 37 is adjustable, so that the clearance between flat surfaces 37 and 38 can be adjusted with the help of the guide components 43.
    [0066] The second linear guide 36 forms, in this case, a movable bearing, whereas the tubular line of the first linear line 34 constitutes the fixed bearing.
    [0067] The tubular line consists of an inner tube 33, fixedly connected over flange components 42 on the underside of the machine frame 8, and in this tube a hollow roller 35, fixedly connected with the milling roller housing 10, can slide.
    [0068] A piston and roller unit 45, attached with one end to the machine frame 8 and to the other end, in the milling roller housing 10, can move the entire milling roller housing unit 10 with the milling roller 12 and the other elements of the milling roller housing 10 shown in figures 2 and 3, including the lower end 44 of the conveyor device assembly 18, between a position of the milling roller 12 on the left or on the right side, in relation to the external side of the road mill 1.
    [0069] The stroke of the piston and roller set 45 is preferably between approximately 500 and approximately 1000 mm. This means that the cutter roll housing 10 with all the components shown in figures 2 and 3 can be displaced from this trace transversely in relation to the direction of trace 31. If, for example, the front side of the cutter roll 12 is in a position on the left side, in the direction of trace 31, of the machine, in addition to or in the vicinity of the external side 26,28, then the zero side of the machine is on the left side.
    [0070] The stroke of the piston and roller set 45 must be seen in relation to the width of the milling roll 12 which in the case of large cutters is approximately 1500 mm, and more, typically 2000 mm. The piston and roller roller 45 can apply sufficiently intense forces to dislodge the hobbing roller housing 10 with the hobbing roller 12, also during the milling operation. For this purpose, additional tools 13 can be provided on the milled roll, on the respective front sides.
    [0071] Two guides 34, 36 linear, spaced in the direction of the machine frame 8 displacement, preferably have the greatest possible distance between them. They can transfer the weight of the machine to the cutter roll housing 10 and to the cutter roll 12 mounted thereon, in order to enable intense cutting forces with large cutter depths.
    [0072] The combination of linear guides 34, 36 allows an optimum capture of incident forces and torques.
    [0073] The side plate 15 is secured on both sides of the hobbing roller housing 10, by means of a double set of piston roller units 17, the double set enabling a particularly high stroke of the piston roller units 17.
    [0074] As can be seen only 2, the execution example of a milling roller driver 14 can have at least one hydraulic driver 80 that is integrated in the front side 22 of the milling roll 12. The execution example shown shows a hydraulic actuator 80, bilateral on the two front sides 22 of the milling roll 12, with hydraulic supply lines 82 to the actuators 80 being connected through a distributor 84 and through other hydraulic lines 86 with a hydraulic pump, driven by the motor combustion 3.
    [0075] The other hydraulic lines 86 are shown schematically as a single line. It is understood that at least one hydraulic actuator 80 is required, at least one supply line and a return line, that is, a recycling line. The distributor 84 is fixedly mounted on the milling roller 10, so that the hydraulic lines 822 do not need to be flexible, and only the other hydraulic lines 86 must be so deformable that the trace of displacement of the mobile unit, as can be seen. seen in figure 2, can be performed.
    [0076] In figures 2 and 3, on the front side of the defensive roller housing 10, a track shoe 40 is used which serves to receive the lower end 44 of the conveyor belt assembly 18.
    [0077] The track shoe 40 receives the lower end 44 of the conveyor belt set 18. The track shoe 40 is arranged in the center with respect to an ejection opening 11 of the milling roller housing 10 and can be moved in its height with the aid of synchronous driving 60. Synchronous driving 60 consists of two articulated gears 62, arranged next to the conveyor belt assembly 18, with a piston and roller unit 63, with the synchronism of the two articulated gears 62 is secured through a coupling shaft 66, so that the synchronous running guide cannot flex.
    [0078] Figure 3 shows a presentation corresponding to figure 2, with a set of conveyor belt, integrated 18.
    [0079] The front assembly of the conveyor belt assembly18 is best seen in figure 5. In the machine frame, in a fixed position, a support element 56 is arranged on the side of the frame. The support element 56 on the side of the frame preferably has a rounded convex support surface, in the example of execution a tube, which can rest on the support element 52 on the side of the conveyor, at the upper front end 46 of the transport assembly 18. As both support elements 52, 56 have rounded convex support surfaces, the front end 46 of the conveyor belt assembly 18 is mounted in a point direction, the assembly forming a cardan joint. In addition, the support element 52 on the conveyor side can be moved longitudinally when the cutter roller housing 10 is moved from one side to the other side of the road mill 1. The hinged assembly also allows for reduced rolling of the assembly conveyor belt 18.
    [0080] Lateral guides 54 secure the support element 52 in its position on the side of the conveyor.
    [0081] Based on the displacement trace of the milling cutter housing 10, transversely to the direction of travel 31, it is also necessary to retract the lower end 44 of the conveyor belt assembly 18, articulated on the conveyor shoe 40.
    [0082] For the articulated fitting of the lower end 44, the treadmill shoe 40 may have an insert trough 48, essentially concave, preferably spherical, which cooperates with a lower side - suitable for the shape of the insert trough 48 - at the end lower 44 of the conveyor belt assembly 18. This hinged fit of the lower end 44 of the conveyor belt assembly 18 allows a suspension of the belt shoe 40, with the lower end 44 of the conveyor assembly 18, as well as a displacement of the roller housing of milling cutter 10, around a displacement of 500 to 1000 mm, the lower end 44 of the conveyor belt assembly 18 remaining positioned in front of the ejection opening 11 of the roller housing 10.
    [0083] The insert trough 48 is formed by oblique surfaces 50 that accommodate the lower end 44 of the conveyor belt assembly 18. In addition, lateral conductive elements 51 are provided that allow, on the one hand, the lower end 44 to rotate around an elevated axis, but, on the other hand, holds the lower end 44 laterally in position. The lower end 44 of the conveyor belt assembly 18 has in the center, on the lower side, a support assembly 49 in figure 2 only shown in dashed form, this assembly being preferably spherical and resting on the conveyor shoe 40 in operation, in front of the oblique plane 50, central in the track shoe 40. In the support element 49 in its support position, dashed lines are also shown in figure 5.
    [0084] The ejection opening 11 of the cutter roller housing 10 need not be arranged in the center with respect to the cutter roller housing 10, but may also be provided in an eccentric position. The tools 13 on the cutter roll 12 are circumferentially arranged in a spiral shape, with the cutter roll 12 having opposite projection spirals of tools 13 and transporting the material removed during milling to the ejection opening 11 and displacing them from the ejection opening 11 towards the conveyor belt assembly 18.
    [0085] Figure 4 shows a rear view in perspective of the housing of the milling roller 10, on which, with the aid of piston roller units 65, the scraping plate 64 of adjustable height is arranged. The scraper plate 64 can also be rotated upwards, when the tools 13 on the milling roll 12 must be accessible.
    [0086] On its side facing the milling roll 12, the scraping plate 64 has a movable plate 74 on its lateral side edges which, with the aid of an elastic prestressing set 76 (figure 4) can be compressed against the cutter edge 70 (figure 1) that protrudes in an orthogonal direction towards the road surface 2.
    [0087] The lower edge 78 of the side moving plate element 74 closes the top with the lower edge of the scraping plate 64. The plate elements 74 can be adjusted in height, together with the scraping plate 64. The sets of prestressing elastics 76 can produce prestressing differently. In the execution example of figure 4, the prestressing sets 76 are presented as piston-roller elements that can be hydraulically prestressed.
