Description

[0001] Processing machine and method for track processing

[0002] This patent application claims priority from German patent application DE 10 2023 207 490.7, the contents of which are incorporated herein by reference.

[0003] The invention relates to a processing machine and a method for track processing. In particular, the invention relates to a processing machine that can be moved along a first rail for track processing and supported on an adjacent second rail.

[0004] US 2 884 867 A discloses a processing machine for track processing, which is used to drive rail nails. The processing machine comprises a carrier on which two guide rollers are arranged one after the other in a longitudinal direction of the rail, so that the processing machine can be manually moved along a first rail using handles. A boom with a rotatably mounted roller is arranged on the carrier, so that the processing machine is supported on an adjacent second rail. The boom with the roller is detachably connected to the carrier. Processing units are arranged on the carrier, which serve to drive the rail nails. The processing machine has wheels attached to the carrier for transport and rerailing.The axes of rotation of the wheels run perpendicular to the axes of rotation of the guide rollers, so that the processing machine can be moved sideways to a rail and re-railed by a pivoting movement around the axes of rotation of the wheels.

[0005] The invention is based on the object of creating a processing machine that enables simple, flexible, user-friendly and efficient track processing.

[0006] This object is achieved by a processing machine with the features of claim 1. Because the angle α between the first displacement direction of the rail displacement unit and the second displacement direction of the terrain displacement unit is -45° < α < 45°, the processing machine can be displaced by an operator both on a rail and on terrain without the need to change grip. The at least one handle can therefore be used by an operator both to displace the processing machine on a rail and to displace it on terrain. The following applies in particular to the angle α: -10° < α < 10°, in particular -5° < α < 5°, and in particular α = 0°. The first displacement direction and the second displacement direction preferably run parallel to one another. The angle α applies in particular when the processing machine is in a processing state.

[0007] According to the invention, it was recognized that the processing machine known in the prior art has the disadvantage that a first displacement direction of the rail displacement unit and a second displacement direction of the terrain displacement unit enclose an angle of 90°. As a result, an operator cannot grasp the processing machine by the handles provided for moving it on the rail when moving it on the terrain, but must instead grasp the processing machine by another means, for example, by a machine frame. This is operator-unfriendly and makes it impossible to move the processing machine over long distances on the terrain.

[0008] In contrast, the inventive alignment of the second displacement direction relative to the first displacement direction makes it simple, flexible, and user-friendly to move the processing machine using the terrain displacement unit. The at least one handle used by an operator to move the processing machine on the rail can also be used to move the processing machine off-road, so that an operator does not have to change his grip and can move the processing machine in an upright position even over longer distances off-road. This improves the efficiency of the processing machine and track processing. The processing device comprises, in particular, a support and at least one processing unit arranged thereon for processing the track. The at least one handle is attached to the processing device, in particular to the support.Preferably, the at least one handle is height-adjustable in a vertical direction. The processing machine comprises, in particular, at least two handles that are arranged at a distance from one another in a transverse direction and / or are height-adjustable in a vertical direction. The rail displacement unit comprises at least one rail displacement element, in particular at least two rail displacement elements.

The at least one rail displacement element is rotatable about a respective first axis of rotation. The terrain displacement unit comprises at least one terrain displacement element, in particular at least two terrain displacement elements.

The first displacement direction Ri and the second displacement direction R2 run parallel to one another.

[0070] The first rail displacement element 30 and the second rail displacement element 31 are arranged to be rotatable about a respective first axis of rotation Di. Accordingly, the first terrain displacement element 32 and the second terrain displacement element 33 are arranged to be rotatable about a respective second axis of rotation D2. The first axes of rotation Di run parallel to the transverse direction y and parallel to one another. Accordingly, the second axes of rotation D2 run parallel to the transverse direction y and parallel to one another. The first axes of rotation Di form an angle α with the second axes of rotation D2, where α = 0°. Accordingly, the first axes of rotation Di run parallel to the second axes of rotation D2. The first axes of rotation Di and the second axes of rotation D2 run in the x-y plane.

The processing machine 1 comprises a positioning drive 37 for actuating the positioning mechanisms 36. The respective positioning mechanism 36 comprises a first rod 38, a second rod 40 and a third rod 42 for positioning the first rail displacement element 30. The first rod 38 is mounted on the base body 29 between a first free end and a second free end so that it can pivot about a first pivot axis 44. The first rail displacement element 30 is mounted on the first free end of the first rod 38 so that it can rotate about the first axis of rotation Di. In contrast, a first free end of the second rod 40 is pivotally mounted on the second free end of the first rod 38.The third rod 42 is pivotally mounted centrally on the joint unit 8 about a third pivot axis 43. A first free end of the third rod 42 is pivotally connected to a second free end of the second rod 40.

[0072] For positioning the second rail displacement element 31, the respective positioning mechanism 36 comprises a first rod 39, a second rod 41 and the third rod 42. The first rod 39 is pivotally mounted on the base body 29 between a first free end and a second free end about a second pivot axis 45. The second rail displacement element 31 is rotatably mounted about the first rotation axis Di at the first free end of the first rod 39. A first free end of the second rod 41 is pivotally mounted at the second free end of the first rod 39. The second free end of the third rod 42 is pivotally connected to the second free end of the second rod 41.

[0073] The terrain displacement unit 28 is fixedly arranged on the base body 29 in the vertical direction z, whereas the rail displacement unit 26 can be adjusted in the vertical direction z relative to the base body 29 and the terrain displacement unit 28 by means of the positioning mechanisms 36. The rail displacement unit 26 is positioned in the vertical direction z by pivoting the respective third rod 42 about the pivot axis 43, whereby the first rods 38, 39 are pivoted about the associated pivot axes 44, 45 and the first rail displacement element 30 and the second rail displacement element 31 are simultaneously positioned in the vertical direction z. The positioning mechanisms 36 are actuated by means of the positioning drive 37. The positioning drive 37 comprises a double-acting piston-cylinder unit 46 and an associated pump 47.The pump 47 is arranged on the carrier 6 and is connected to the double-acting piston-cylinder unit 46 via fluid lines not shown in detail.

[0074] The piston-cylinder unit 46 is hinged to the base body 29 and the second free end of the third rod 42. The positioning mechanism 36 and the positioning drive 37 are illustrated in Fig. 1.

[0075] For locking the joint unit 8, the processing machine 1 comprises a locking unit 48. The locking unit 48 is not locked in a processing state of the processing machine 1, whereas the locking unit 48 is locked in an off-road transport state of the processing machine 1. The locking unit 48 is illustrated in Figures 4 and 7.

[0076] The locking unit 48 comprises an actuator 49, which is designed as a double-acting piston-cylinder unit with a cylinder 50 and a locking pin 51 as a piston. The locking pin 51 serves to lock the horizontal pivot axis SH and the vertical pivot axis Sv of the joint unit 8. The third rod 42 is pivotally mounted on the locking pin 51 in the transverse direction y on a first side. On an opposite second side, the locking pin 51 cooperates with a locking opening 52. The locking opening 52 is formed in the carrier 6. The locking pin 51 is displaceable in the transverse direction y. For this purpose, the actuator 49 is connected to the pump 47.

[0077] The boom 27 is fastened to the base body 29 in the longitudinal direction x between the first rail displacement element 30 and the second rail displacement element 31, in particular between the first terrain displacement element 32 and the second terrain displacement element 33. The boom 27 comprises a crossbar 53 and a support roller 54. The crossbar 53 is detachably fastened to the base body 29. The crossbar 53 extends in the transverse direction y to the adjacent rail 4. The support roller 54 is rotatably mounted on the free end of the crossbar 53. The support roller 54 serves to support the processing machine 1 on the adjacent rail 4. This is illustrated in Fig. 2.

[0078] The displacement device 7 comprises a displacement drive 55. The displacement drive 55 is integrated into the first terrain displacement element 32. The displacement drive 55 comprises an electric drive motor, which is designed, for example, as a wheel hub motor.

[0079] For control purposes, the processing machine 1 comprises a control device 56. The control device 56 is arranged on the processing device B or on the carrier 6 between the guide rods 23, 24. The control device 56 is connected to the energy supply unit 15. The control device 56 is in signal communication with the control electronics 17, the electric drive motor 18, the positioning drive 37, and the displacement drive 55. The control device 56 serves in particular to control the processing unit 9, the positioning drive 37, the locking unit 48, and the displacement drive 55.

[0080] The operation of the processing machine 1 is as follows:

[0081] For track processing, the processing machine 1 must first be relocated to the track 2 or track section to be processed. For this purpose, the crossbar 53 and the support roller 54 mounted thereon are first removed from the base body 29. The processing machine 1 is relocated or moved to the track 2 by an operator in the terrain G using the terrain relocation unit 28.

[0082] For this purpose, the processing machine 1 is in an off-road transport state. The off-road transport state is illustrated in Figures 5 to 7. In the off-road transport state, the rail displacement unit 26 is deactivated and the off-road displacement unit 28 is activated. For this purpose, the third rod 42 of the respective positioning mechanism 36 is pivoted about the pivot axis 43 by means of the positioning drive 37 such that the rail displacement elements 30, 31 are displaced upwards in the vertical direction z about the associated pivot axes 44, 45. To actuate the positioning mechanism 36, the piston-cylinder unit 46 is subjected to fluid pressure by means of the pump 47 such that the piston-cylinder unit 46 is retracted. The pump 47 additionally activates the locking unit 48. Due to the fluid pressure of the pump 47, the locking unit 48 is brought into a locking position in which the locking pin 51 is arranged in the locking opening 52.The joint unit 8 is thus locked in the off-road transport position. This is illustrated in Fig. 7.

[0083] The terrain displacement unit 28 forms a terrain running surface LG, whereas the rail displacement unit 26 forms a running surface Ls. In the terrain transport state, the rail running surface Ls is arranged higher in the vertical direction z than the terrain running surface LG, whereby the rail displacement unit 26 is deactivated and the terrain displacement unit 28 is activated. For a distance AG between the terrain running surface LG and the rail running surface Ls, the following applies: 0 cm < AG < 10 cm, in particular 1 cm < AG < 8 cm, and in particular 2 cm < AG < 6 cm.

[0084] The terrain displacement elements 32, 33 are in contact with the terrain G in the off-road transport state. By means of the control device 56, an operator can control the displacement drive 55 and move the processing machine 1 in the terrain G. Because the terrain displacement unit 28 is arranged between the first rail displacement element 30 and the second rail displacement element 31, the terrain displacement elements 32, 33 are arranged at a short distance from one another in the longitudinal direction x, so that the processing machine 1 can be moved and steered easily and in a user-friendly manner using the handles 21, 22.

[0085] If the processing machine 1 is located on the track, it is manually lifted onto the rail 3 or moved onto the rail 3 using the terrain displacement unit 28. The crossbar 53 with the support roller 54 is mounted on the base body 29 so that the processing machine 1 is supported on the adjacent rail 4 by means of the boom 27. The processing machine 1 is then transferred by the operator into the processing state. The processing state is illustrated in Figures 1 to 4. In the processing state, the rail displacement unit 26 is activated and the terrain displacement unit 28 is deactivated. For this purpose, the positioning drive 37 pivots the third rod 42 about the pivot axis 43 such that the rail displacement elements 30, 31 are displaced downward in the vertical direction z about the associated pivot axes 44, 45.To this end, the pump 47 applies fluid pressure to the piston-cylinder unit 46 such that the piston-cylinder unit 46 is extended. Furthermore, the pump 47 actuates the locking unit 48. The pump 47 applies fluid pressure to the actuator 49 such that the locking pin 51 is displaced from the locking opening 52 and the joint unit 8 is no longer locked. The carrier 6 or the processing unit 9 can thus be pivoted about the horizontal pivot axis SH and about the vertical pivot axis Sv.

[0086] In the processing state, the terrain running surface LG is arranged higher in the vertical direction z than the rail running surface Ls, whereby the terrain displacement unit 28 is deactivated and the rail displacement unit 26 is activated. For a distance As between the rail running surface Ls and the terrain running surface LG, the following applies in particular: 0 cm < As < 10 cm, in particular 1 cm < As < 8 cm, and in particular 2 cm < As < 6 cm.

[0087] In this processing state, track processing takes place. For this purpose, the track processing machine 1 is manually moved by an operator, and the processing unit 9 is positioned using the handles 21, 22 by pivoting about the horizontal pivot axis SH and the vertical pivot axis Sv. The processing unit 9 is lowered in the vertical direction z by pivoting about the horizontal pivot axis SH, the processing tool 12 is driven in rotation by the electric drive motor 18, and the processing unit 9 is subsequently raised again. The processing unit 9 is then pivoted about the vertical pivot axis Sv, and the track processing is repeated on the other side of the rail 3. The processing machine 1 is then moved by the rail displacement unit 26 to the next track location to be processed, where the track processing described above is repeated.Once track processing is complete, the processing machine 1 is removed from the rails. To do this, the crossbar 53 with the support roller 54 is first removed from the base body 29, and the processing machine 1 is transferred from the processing state back to the off-road transport state. This is done in the reverse manner to that described above. The processing machine 1 is then manually lifted from the rail 3 or moved from the rail 3 using the off-road relocation unit 28. The processing machine 1 can now be moved in the terrain G in the manner already described.

[0088] A second exemplary embodiment of the invention is described below with reference to Figures 8 and 9. The processing state of the processing machine 1 is illustrated in Figure 8, whereas Figure 9 illustrates the off-road transport state of the processing machine 1. In contrast to the first exemplary embodiment, the off-road displacement unit 28 comprises only one off-road displacement element 32. The off-road displacement element 32 is of closed design and runs around the base body 29. The off-road displacement element 32 is, for example, a belt or a chain. The off-road displacement element 32 is arranged in the longitudinal direction x between the first rail displacement element 30 and the second rail displacement element 31. The off-road displacement element 32 is displaceable in a circumferential direction around the base body 29 and around the second axes of rotation D2.The terrain displacement element 32 is displaced by means of the displacement drive 55. The angle a is: a = 0°. Regarding the further structure and operation of the processing machine 1, reference is made to the previous embodiment.

[0089] A third exemplary embodiment of the invention is described below with reference to Figures 10 to 14. Figures 10 and 11 show the processing machine 1 in a processing state, whereas Figure 12 shows the processing machine 1 in a rail transport state, and Figures 13 and 14 show it in an off-road transport state. The processing machine 1 is designed according to the first exemplary embodiment, but has a simplified positioning mechanism 36 and no positioning drive 37. The first rail displacement element 30 is mounted on a rod 57 for rotation about the first axis of rotation Di. The rod 57 is fastened to the base support 29 with its free end for pivoting about the first pivot axis 44.The second rail displacement element 31 is mounted on a rod 58, which is rotatable about the first rotation axis Di and is attached to the base body 29 with its free end pivotable about the second pivot axis 45. The rail displacement unit 26 is manually positioned in the vertical direction z. The locking unit 48 is also manually operated. For this purpose, an actuating lever 59 is arranged on the locking bolt 51.

[0090] Figures 10 and 11 illustrate the processing machine 1 in the processing state, in which the rail displacement unit 26 is activated and the terrain displacement unit 28 is deactivated. In the processing state, the locking unit 48 is not locked, so that the processing unit 9 can be pivoted about the horizontal pivot axis SH and the vertical pivot axis Sv.

[0091] Fig. 12 shows a rail transport state of the processing machine 1 in which both the rail displacement unit 26 and the terrain displacement unit 28 are activated.

[0092] The rail running surfaces Ls of the rail displacement elements 30, 31 and the ground running surfaces LG of the ground displacement elements 32, 33 rest on the rail 3. As a result, the processing machine 1 is guided on the rail 3 by means of the rail displacement elements 30, 31. The processing machine 1 can be moved on the rail 3 by means of the ground displacement element 32, which is rotatably driven by the displacement drive 55. The locking unit 48 can be locked or unlocked in the rail transport state.

[0093] Figures 13 and 14 illustrate an off-road transport state of the processing machine 1. In the off-road transport state, the rail displacement elements 30, 31 are pivoted upwards in the vertical direction z about the pivot axes 44, 45. The rail displacement unit 26 is thus deactivated, whereas the off-road displacement unit 28 is activated. The off-road displacement elements 32, 33 contact the off-road G. The locking unit 48 is locked. The locking pin 51 is arranged in the locking opening 52 by means of the actuating lever 59. The processing machine 1 can be moved and manually guided by an operator in the off-road G using the handles 21, 22 and the displacement drive 55. With regard to the further structure and further functioning of the processing machine 1, reference is made to the preceding exemplary embodiments.

[0094] A fourth exemplary embodiment of the invention is described below with reference to Figures 15 to 17. The processing machine 1 is designed according to the second exemplary embodiment, but, according to the third exemplary embodiment, has a simplified positioning mechanism 36 and no positioning drive 37. Fig. 15 illustrates the processing machine 1 in a processing state in which the rail displacement unit 26 is activated and the terrain displacement unit 28 is deactivated. Fig. 16 illustrates the processing machine 1 in a rail transport state in which both the rail displacement unit 26 and the terrain displacement unit 28 are activated. The rail running surfaces Ls of the rail displacement elements 30, 31 and the terrain running surface LG of the terrain displacement element 32 rest on the rail 3.As a result, the processing machine 1 is guided on the rail 3 by means of the rail displacement elements 30, 31 and can be moved on the rail 3 by means of the terrain displacement element 32, which can be driven in rotation by the displacement drive 55.

[0095] Fig. 17 illustrates the processing machine 1 in a terrain transport state in which the rail displacement unit 26 is deactivated and the terrain displacement unit 28 is activated. Regarding the further structure and further functioning of the processing machine 1, reference is made to the preceding embodiments.

[0096] A fifth embodiment of the invention is described below with reference to Figs. 18 to 21. In contrast to the previous embodiments, the terrain displacement unit 28 is arranged on the processing device B. The first terrain displacement element 32 and the second terrain displacement element 33 are arranged next to one another in the transverse direction y and between the first rail displacement element 30 and the second rail displacement element 31 in the longitudinal direction x. The first terrain displacement element 32 and the second terrain displacement element 33 are each designed as a wheel. A respective displacement drive 55 is integrated into the terrain displacement elements 32, 33.

[0097] The positioning mechanisms 36 serve to position the terrain displacement elements 32, 33 in the vertical direction z. For this purpose, the respective positioning mechanism 36 comprises a suspension 60, which is pivotably mounted on the processing device B about a pivot axis 61. The terrain displacement elements 32, 33 are mounted on the respective suspension 60 at a distance from the pivot axis 61 and are rotatable about the second rotation axis D2.

[0098] The respective positioning mechanism 36 comprises a fixing unit 62 for fixing the associated suspension 60 in a pivoting position about the pivot axis 61.

[0099] In contrast to the previous embodiments, the rail displacement elements 30, 31 are arranged on the base body 29 in a fixed manner in the vertical direction z and are rotatable about the respective first axis of rotation Di.

[0100] Figs. 18 and 19 illustrate the processing machine 1 in a processing state in which the rail displacement unit 26 is activated and the terrain displacement unit 28 is deactivated. To deactivate the terrain displacement unit 28, the booms 60 are pivoted upward about the pivot axis 61 and fixed in the pivot position shown in Figs. 18 and 19 by means of the fixing unit 62.

[0101] Fig. 20 illustrates the processing machine 1 in a rail transport state. In the rail transport state, the rail displacement unit 26 and the terrain displacement unit 28 are activated. The rail transport state is identical to the terrain transport state illustrated in Fig. 21. The boom 27 is disassembled. The suspensions 60 are pivoted downward about the pivot axis 61 and fixed in the pivot position illustrated in Fig. 20 by means of the fixing units 62. In this pivot position, the terrain displacement elements 32, 33 rest with their terrain running surfaces LG against the rail foot of the rail 3. In the rail transport state, the processing machine 1 can be moved on the rail foot by means of the terrain displacement elements 32, 33, wherein the processing machine 1 is guided on the rail 3 by means of the rail displacement elements 30, 31. Fig.Figure 21 illustrates the processing machine 1 in the off-road transport state. In the off-road transport state, the rail displacement unit 26 is deactivated and the off-road displacement unit 28 is activated. The off-road displacement elements 32, 33 contact the off-road G with their off-road running surfaces LG. The processing machine 1 can be moved by means of the displacement drives 55 and guided by means of the handles 21, 22. Regarding the further structure and further functioning of the processing machine 1, reference is made to the preceding embodiments.

[0102] The features of the individual embodiments can be combined with one another in any way. For example, the positioning drive 37 can act only on the positioning mechanism 36, and the locking unit 48 can be operated only manually.
