This application claims the priority, under 35 U.S.C. § 119, of German Patent Application DE 10 2023 203 452.2, filed Apr. 17, 2023; the prior application is herewith incorporated by reference in its entirety.
The invention relates to a processing machine and a method for track processing. In particular, the invention relates to a processing machine which can be moved on a first rail and supported on an adjacent second rail for track processing.
German Utility Model DE 20 2016 006 565 U1 discloses a processing machine for track machining in the form of a screwing machine. The screwing machine includes a supporting frame on which two flanged rollers are disposed one after the other in the longitudinal rail direction, so that the screwing machine can be moved manually on a first rail by a handle. A cantilever beam is disposed at the supporting frame with a track roller rotatably mounted thereto, so that the screwing machine is supported on an adjacent second rail. The cantilever beam with the track roller is easily detachably connected to the supporting frame. The screwing machine includes two screwing units which are fastened to the supporting frame on both sides of the flanged rollers so that screws disposed on both sides of the first rail can be tightened or loosened. Due to the fact that the screwing machine can be displaced on only one rail and is merely supported on the adjacent rail, the screwing machine can be easily placed on the track and removed from it.
It is accordingly an object of the invention to provide a processing machine and a method for track processing, which overcome the hereinafore-mentioned disadvantages of the heretofore-known machines and methods of this general type and which enable simple, flexible, operator-friendly and efficient track processing.
With the foregoing and other objects in view there is provided, in accordance with the invention, a processing machine for track processing, comprising a carrier, a displacement mechanism disposed at the carrier, at least one processing unit disposed at the carrier for processing a track, and at least one handle for manually guiding the processing machine, wherein the displacement mechanism includes at least one rail-ground displacement unit for displacing the processing machine on a rail and on the ground. The displacement mechanism disposed on the carrier of the processing machine includes at least one rail-ground displacement unit for displacing the processing machine on a rail and on the ground. According to the invention, it has been recognized that with the processing machines known in the prior art, transport to the track to be processed is often difficult and user-unfriendly, as the processing machines are difficult or impossible to move manually on the ground and must therefore be regularly carried manually or transported to and from the site at great expense by auxiliary vehicles. Due to the fact that the displacement mechanism of the processing machine according to the invention includes at least one rail-ground displacement unit, simple, flexible and operator-friendly displacement of the processing machine on the ground to the track to be processed and displacement of the processing machine on a rail during track processing is possible. This improves the efficiency of the processing machine and track processing.
Preferably, the processing machine includes at least a first displacement unit and a second displacement unit disposed at the carrier. The first displacement unit is a rail-ground displacement unit. In contrast, the second displacement unit can be a rail displacement unit or a ground displacement unit or a rail-ground displacement unit. Preferably, both the first displacement unit is a rail-ground displacement unit and the second displacement unit is a rail-ground displacement unit. The first displacement unit and the second displacement unit are disposed one after the other in a longitudinal direction of the carrier, which corresponds to a longitudinal rail direction. The first rail-ground displacement unit and the second rail-ground displacement unit thus serve to arrange the carrier on the same rail. Preferably, the first displacement unit and the second displacement unit are disposed at the ends of the carrier in the longitudinal direction. The rail displacement unit is configured, for example, as a flanged roller or guiding roller. The ground displacement unit is configured as a wheel, for example.
The at least one rail-ground displacement unit, in particular the respective rail-ground displacement unit, is configured in an integrated manner. This means that the rail-ground displacement unit is not configured by a separate rail displacement unit and by a separate ground displacement unit, which are adjustable relative to one another, in particular adjustable in height, so that either the rail displacement unit or the ground displacement unit is in use.
The at least one rail-ground displacement unit, in particular the respective rail-ground displacement unit, is preferably disposed in a suspended manner at the carrier.

The at least one ground running surface and/or the at least one rail running surface can be directly configured by the displacement base body. The displacement base body can be configured with a round or polygonal cross-section with rounded corners.
The at least one rail-ground displacement unit, in particular the respective rail-ground displacement unit, includes in particular at least one contact element disposed on a displacement base body. The at least one contact element preferably forms the at least one ground running surface and/or the at least one rail running surface. The at least one contact element can be constructed from a metallic material, a plastic material and/or an elastomer material. The plastic material includes, for example, a thermoplastic plastic material and/or a thermosetting plastic material. The at least one contact element is disposed in particular in a fixed and/or displaceable manner at the displacement base body. In particular, the at least one contact element can be displaced in a circumferential direction around the displacement base body and/or can be displaced in a transverse direction, i.e. laterally to the displacement base body.
The at least one contact element is configured in particular as a chain and/or belt, for example as a metal chain, rubber chain and/or rubber belt. In particular, the chain and/or the belt is configured to run around the displacement base body and is of closed configuration. The chain and/or the belt is disposed at the displacement base body and is preferably displaceable in a circumferential direction around the displacement base body and/or in a transverse direction, i.e. laterally to the displacement base body. The chain and/or the belt preferably form the at least one ground running surface and/or the at least one rail running surface.
The at least one contact element is configured in particular as a ring. In particular, the ring is constructed from a metallic material, a plastic material and/or an elastomer material. Preferably, a first ring and a second ring are disposed as contact elements at the displacement base body, which is configured in the shape of a wheel or round in cross-section. Preferably, at least one ring, in particular both rings, can be displaced in a transverse direction relative to the displacement base body. In particular, the at least one ring forms the at least one ground running surface and/or the at least one rail running surface. Preferably, the displacement base body forms a rail running surface and two rings each form a ground running surface.
Preferably, the at least one ground running surface has a greater distance than the at least one rail running surface from a central longitudinal axis of the displacement base body.

In particular, the at least one ground running surface has elevations in a circumferential direction and/or in a transverse direction of the displacement base body. The elevations are configured in particular as knobs and/or studs.
A processing machine in which the at least one rail-ground displacement unit forms a running surface which includes two ground running surfaces and a rail running surface disposed therebetween ensures simple, flexible, operator-friendly and efficient track processing. Due to the fact that the rail running surface is configured in a transverse direction between the two ground running surfaces, the running surface can be adapted to the cross-section of a rail. Preferably, a distance AG of the ground running surfaces from a central longitudinal axis of the displacement base body is greater than a distance AS of the rail running surface, so that the running surface forms a recess for receiving a rail head of the rail. The distance between the two ground running surfaces can be adjusted, in particular in a transverse direction, i.e. in the direction of the central longitudinal axis of the displacement base body. This allows the running surface to be adapted to rail heads of different widths. For example, the ground running surfaces are configured by two rings that are disposed adjustably on a wheel-shaped or cross-sectionally round displacement base body. An adjustment mechanism serves in particular for adjustment. The adjustment mechanism can preferably be locked in a desired position.
A processing machine in which the at least one rail-ground displacement unit forms a running surface with a recess for receiving a rail head of a rail ensures simple, flexible, operator-friendly and efficient track processing. Viewed in cross-section, the running surface forms, at least in sections, a recess for receiving a rail head of a rail. This allows the at least one rail-ground displacement unit, in particular the respective rail-ground displacement unit, to be guided and displaced on a rail in a simple and operator-friendly manner. Due to the recess, the running surface is centered relative to the rail itself. In particular, the recess has a widening cross-section. The widening cross-section is preferably formed in a V-shape and/or U-shape. In particular, the cross-sectional shape of the recess can be adjusted, for example due to the fact that at least one ground running surface can be displaced relative to a rail running surface, in particular in a transverse direction of a displacement base body. This allows the recess to be adapted to different sizes of rail heads. For example, the ground running surface is formed by a ring which is fastened to the displacement base body so as to be adjustable in a transverse direction.
The at least one rail-ground displacement unit, in particular the respective rail-ground displacement unit, preferably forms a running surface which includes two ground running surfaces and a rail running surface disposed therebetween. Preferably, the ground running surfaces are configured to be profiled in a circumferential direction and/or in a transverse direction of the displacement base body. In particular, the at least one ground running surface has elevations in a circumferential direction and/or in a transverse direction of the displacement base body. The elevations are configured in particular as knobs and/or studs. In particular, the elevations have a chamfer and/or a rounding towards the rail running surface. This allows the running surface to adapt to rail heads of different widths without the need for adjustment.
A processing machine in which the at least one rail-ground displacement unit includes a displacement drive ensures simple, flexible, operator-friendly and efficient track processing. Preferably, a rail-ground displacement unit or a plurality of rail-ground displacement units or each rail-ground displacement unit includes an associated displacement drive.

The respective displacement drive serves in particular to drive a displacement base body of the rail-ground displacement unit about a central longitudinal axis and/or to drive a contact element in the circumferential direction about a displacement base body of the rail-ground displacement unit. The displacement drive can be integrated into the associated displacement base body. In particular, the processing machine includes a control device for controlling the respective displacement drive. In particular, the control device is configured in such a manner that the displacement drives can be controlled independently of and/or synchronously with one another.

In particular, the at least one steering unit can be swiveled about a vertical swivel axis relative to the carrier. The at least one steering unit preferably serves for manual swiveling. The at least one steering unit includes, for example, a swivel bearing, a steering linkage and/or at least one handle, in particular at least two handles.

The first rail-ground displacement unit and the second rail-ground displacement unit are disposed in particular at the end and/or in a suspended manner at the carrier. The longitudinal direction corresponds to a longitudinal rail direction. Due to the fact that the rail-ground displacement units are disposed in a suspended manner at the carrier, the rail-ground displacement units and the carrier delimit a receiving space which is open towards a rail.

In particular, the control mechanism evaluates measurement data from the detection unit and uses this data to generate control signals for the at least one positioning mechanism and/or the at least one processing unit.
A processing machine in which the displacement mechanism includes a cantilever beam for being supported on a rail ensures simple, flexible, operator-friendly and efficient track processing. The at least one processing unit disposed at the carrier is disposed on a rail, in particular on exactly one rail, by at least two displacement units.

This allows the center of gravity of the energy supply unit to be shifted in the transverse direction towards an adjacent second rail, so that the stability of the processing machine in conjunction with a cantilever beam is improved.
It is also an object of the invention to provide a method for track processing that is simple, flexible, operator-friendly and efficient.
With the objects of the invention in view, there is concomitantly provided a method for track processing, comprising the steps of providing a processing machine according to the invention, displacing the processing machine on the ground to a track and on a rail of the track by using the at least one rail-ground displacement unit, and processing the track by using the at least one processing unit.

In particular, the at least one rail-ground displacement unit forms a running surface including at least one ground running surface and at least one rail running surface. The processing machine is basically displaced on the ground by the at least one ground running surface. The at least one ground running surface has sufficient grip on the ground so that the processing machine can be displaced, in particular moved, to the track to be processed in a simple, flexible, operator-friendly and efficient manner. In contrast, the at least one rail running surface, in particular in conjunction with the at least one ground running surface, enables simple and operator-friendly displacement on a rail of the track. For this purpose, the running surface is configured in particular with a recess so that the running surface centers itself relative to the rail.

If the steering units are swiveled in the same directions and by the same angles, the processing machine is displaced, in particular linearly and at an angle, i.e. transversely. If, on the other hand, the steering units are swiveled in opposite directions, the processing machine is displaced in particular along a curve.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a processing machine and a method for track processing, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
Referring now to the figures of the drawings in detail and first, particularly, to
The processing machine 1 includes a carrier 6, which defines a longitudinal direction x and a transverse direction y running perpendicular thereto. The carrier 6 extends substantially in the longitudinal direction x. The processing machine 1 further includes a displacement mechanism 7 disposed at the carrier 6.
The displacement mechanism 7 has a first rail-ground displacement unit 8 and a second rail-ground displacement unit 9. The first rail-ground displacement unit 8 is fastened to a first end of the carrier 6 by a fork-shaped first fastening element 10, whereas the second rail-ground displacement unit 9 is fastened to a second end of the carrier 6 by a fork-shaped second fastening element 11. The rail-ground displacement units 8, 9 serve to displace the carrier 6 on the rail 3.
The carrier 6, the rail-ground displacement units 8, 9 and the fastening elements 10, 11 delimit a receiving space 12, which is open on a side facing away from the carrier 6. The receiving space 12 serves to at least partially accommodate a first processing unit 13, a second processing unit 14, an associated positioning mechanism 15 and an associated energy supply unit 16.
The positioning mechanism 15 is fastened in a suspended manner to an underside of the carrier 6. The first processing unit 13 is fastened to the positioning mechanism 15 on a first side of the carrier 6 when viewed in the transverse direction y, whereas the second processing unit 14 is fastened to the positioning mechanism 15 on a second side of the carrier 6. The positioning mechanism 15 includes a first positioning drive 17 for positioning the first processing unit 13 and/or the second processing unit 14 in the transverse direction y. Furthermore, the positioning mechanism 15 includes a second positioning drive 18 for positioning the first processing unit 13 and the second processing unit 14 in a vertical direction z. The vertical direction z runs perpendicular to the longitudinal direction x and the transverse direction y. The longitudinal direction x, the transverse direction y and the vertical direction z form a Cartesian coordinate system.
The processing units 13, 14 serve, for example, for screwing. Alternatively, the processing units 13, 14 can also be configured for drilling, clipping, spike punching, spike pulling and/or grinding. The processing units 13, 14 are fastened in a suspended manner to the underside of the carrier 6 by using the positioning mechanism 15. The processing units 13, 14 each include a tool drive 19, which drives a processing tool 20 in rotation about an axis of rotation 21.
The energy supply unit 16 is disposed in a suspended manner at the carrier 6 in the longitudinal direction x between the positioning mechanism 15 and the second rail-ground displacement unit 9. The energy supply unit 16 includes a housing 22 in which a plurality of accumulators 23 are disposed. The accumulators 23 are connected in parallel and/or in series. The accumulators 23 serve to provide electrical energy. The energy supply unit 16 further includes an adjustment mechanism 24, which enables the position of the housing 22 relative to the carrier 6 to be adjusted in the transverse direction y. The adjustment mechanism 24 is configured, for example, as a linear guide. In particular, the linear guide can be locked in a desired position.
The displacement mechanism 7 includes a cantilever beam 25. The
cantilever beam 25 is fastened to the carrier 6 in the longitudinal direction x between the processing units 13, 14 and the energy supply unit 16. The cantilever beam 25 has a holder 26, a transverse rod 27 and a supporting roller 28. The holder 26 is fastened to the carrier 6 and extends in the vertical direction z into the receiving space 12. The transverse rod 27, which extends in the transverse direction y to the adjacent rail 4, is detachably fastened to the holder 26. The supporting roller 28 is rotatably mounted at the free end of the transverse rod 27. The supporting roller 28 serves to support the carrier 6 and the rail-ground displacement units 8, 9 disposed thereon on the adjacent rail 4. This is illustrated in
The displacement mechanism 7 includes a steering unit 29 for swiveling the first rail-ground displacement unit 8 about a vertical swivel axis 30. The steering unit 29 includes a swivel bearing 31, a steering linkage 32 and handles 33, 34. The fork-shaped fastening element 10 is mounted on the carrier 6 so that it can be swiveled about the swivel axis 30 by the swivel bearing 31. The steering linkage 32 is fastened to the fork-shaped fastening element 10. The steering linkage 32 is constructed in a U-shape. The first handle 33 and the second handle 34 are fastened to the free ends of the steering linkage 32. The handles 33, 34 serve to guide and steer the processing machine 1 on the rail 3 or rails 3, 4 and on the ground G surrounding the track 2. The second rail-ground displacement unit 9 is disposed on the carrier 6 so that it cannot be steered. For this purpose, the fork-shaped fastening element 11 is firmly connected to the carrier 6.
The rail-ground displacement units 8, 9 are constructed identically, so that only the rail-ground displacement unit 8 is described in detail below. The rail-ground displacement unit 8 includes a displacement base body 35, a displacement drive 36 and a contact element 37. The displacement base body 35 is fastened to the fastening element 10 or 11 and cannot be rotated relative to the latter. The displacement base body 35 is polygonal in cross-section, in particular rectangular, and in particular square, and has rounded corners. The displacement base body 35 defines a central longitudinal axis M. In the steering position shown in
The respective contact element 37 forms a running surface which includes a first ground running surface LG1, a rail running surface LS and a second ground running surface LG2 in the transverse direction y or in the direction of the central longitudinal axis M. The rail running surface LS is disposed in the direction of the central longitudinal axis M between the ground running surfaces LG1, LG2. The ground running surfaces LG1, LG2 and the rail running surface LS run around the central longitudinal axis M or the displacement base body 35 in accordance with the contact element 37.
The ground running surfaces LG1, LG2 are configured to be profiled in the circumferential direction U and in the direction of the central longitudinal axis M. For this purpose, the contact element 37 has elevations 38, which are configured as nubs or studs, for example. The elevations 38 at least partially form the ground running surfaces LG1, LG2. The ground running surfaces LG1, LG2 have a maximum distance AG from the central longitudinal axis M, whereas the rail running surface LS has a maximum distance AS from the central longitudinal axis M. The following applies: AG>AS. For the distance AG, in particular: 5 cm≤AG≤30 cm, in particular 10 cm≤AG≤25 cm, and in particular 15 cm≤AG≤20 cm. For the distance AS, in particular: 4 cm≤AS≤29 cm, in particular 9 cm≤AS≤24 cm, and in particular 14 cm≤AS≤19 cm. For a difference ΔA=AG−AS, in particular: 1 cm≤ΔA≤8 cm, in particular 2 cm≤ΔA≤7 cm, and in particular 3 cm≤ΔA≤6 cm.
The running surfaces define in cross-section, at least in sections, a recess V for receiving a rail head of the rail 3. The recess V widens in cross-section in a direction transverse to the central longitudinal axis M. For this purpose, the elevations 38 have a chamfer and/or a rounding in a region 39 facing the rail running surface LS. Due to the widening cross-section of the recess V, rail heads of different widths can be accommodated.
The first positioning drive 17, the second positioning drive 18, the tool drives 19 and the displacement drives 36 are configured electrically, in particular. For controlling, the processing machine 1 includes a control mechanism 40, which is disposed at the steering linkage 32.
The operating principle of the processing machine 1 is as follows:
For track processing, the processing machine 1 must first be moved to the track 2 or track section to be processed. For this purpose, the transverse rod 27 and the supporting roller 28 disposed thereon are first removed from the holder 26. The processing machine 1 is displaced or moved to the track 2 by an operator on the ground G by using the rail-ground displacement units 8, 9. For this purpose, the contact elements 37 are displaced in the circumferential direction U around the respective displacement base body 35 by using the displacement drives 36. Through the use of the steering unit 29, the operator can steer the processing machine 1 in a desired direction. Due to the ground running surfaces LG1, LG2, the processing machine 1 has sufficient grip on the ground G, so that the rail-ground displacement units 8, 9 have good traction on the ground G. Due to the fact that the distance AG is greater than the distance AS, the rail running surface LS is simultaneously protected from damage on the ground G.
If the processing machine 1 is located on the track 2, the processing machine 1 is manually lifted onto the rail 3 or moved onto the rail 3 with the aid of the rail-ground displacement units 8, 9 and the transverse rod 27 with the supporting roller 28 is mounted on the holder 26 so that the processing machine 1 is supported on the adjacent rail 4 by the cantilever beam 25. In order to increase the stable position of the processing machine 1, the housing 22 with the accumulators 23 disposed therein is shifted towards the rail 4 by using the adjustment mechanism 24, so that the center of gravity of the processing machine 1 is located between the rails 3, 4.
The rail head of the rail 3 is now located in the recesses V of the running surfaces, wherein the rail running surfaces LS of the rail-ground displacement units 8, 9 rest on the rail head of the rail 3. The ground running surfaces LG1, LG2 rest laterally against the rail head and center the rail-ground displacement units 8, 9 on the rail 3.
The processing units 13, 14 can now be adjusted in the transverse direction y using the positioning mechanism 15. Track processing subsequently takes place. For this purpose, the processing units 13, 14 are lowered in the vertical direction z, the processing tools 20 are driven in rotation by the tool drives 19 and then the processing units 13, 14 are lifted again. The processing machine 1 is now moved by the rail-ground displacement units 8, 9 in the longitudinal rail direction to the next track section to be processed, where the track processing described above is repeated.
Once track processing is finished, the processing machine 1 is removed from the track. For this purpose, the housing 22 with the accumulators 23 is first brought back into a central position relative to the carrier 6 by the adjustment mechanism 24. The transverse rod 27 with the supporting roller 28 is then dismantled from the holder 26 and the processing machine 1 is lifted manually from the rail 3 or moved off the rail 3 using the rail-ground displacement units 8, 9. The processing machine 1 can now be moved on the ground G in the manner already described.

A third exemplary embodiment of the invention is described below with reference to
The first rail-ground displacement unit 8 is fastened to the carrier 6 on one side and rotatable about the central longitudinal axis M by the fastening element 10. Correspondingly, the second rail-ground displacement unit 9 is fastened to the carrier 6 on one side and rotatable about the central longitudinal axis M by the fastening element 11.
The rail-ground displacement units 8, 9 are constructed identically, so that only the rail-ground displacement unit 8 is described below. The rail-ground displacement unit 8 has a wheel-shaped or cross-sectionally round displacement base body 36, which can be driven in rotation about the central longitudinal axis M by the associated displacement drive 36. Ring-shaped contact elements 37 are fastened to the displacement base body 35 by threaded connections 50. The ring-shaped contact elements 37 form the ground running surfaces LG1, LG2, whereas the displacement base body 35 forms the rail running surface LS disposed therebetween. The contact elements 37 are constructed to be profiled in the circumferential direction U and in the direction of the central longitudinal axis M and have the elevations 38. The contact elements 37 form cheeks for the displacement base body 35.
The contact elements 37 can be adjusted relative to the displacement base body 35 in the direction of the central longitudinal axis M by the respective threaded connection 50, so that the recess V can be adapted to rail heads of different widths on the rail 3. This is illustrated in
