The track treatment system 1 comprises at least one track treatment apparatus 2 and a device 3 for positioning the at least one track treatment apparatus 2 on the track 4. The track treatment apparatuses 2 are attached to the device 3 in a detachable manner. In particular, the device is designed to carry a varying number of track treatment apparatuses 2, in particular at least one track treatment apparatus 2. FIGS. 1 to 6 show the track treatment system 1 with two track treatment apparatuses 2 attached to the device 3. In FIGS. 10 to 12, four of the track treatment apparatuses 2 are attached to the device 3. The device 3 is designed to carry and position a maximum of 8 track treatment apparatuses 2.

[0062] The track treatment apparatuses 2 are each designed as tamping units for compacting a ballast bed 5 of the track 4. According to an alternative embodiment not shown, at least one of the track treatment apparatuses can be designed as a screwing unit, in particular for tightening and loosening screw connections, in particular screw connections for fastening rails 6, and/or as a welding unit, in particular for welding the rails 6, and/or as a grinding unit, in particular for grinding the rails 6, and/or as a cleaning unit, in particular for cleaning the track 4.

[0063] The tamping units 2 each have at least two, in particular four, tamping tines 7 for reversible penetration into the ballast bed during compaction. The tamping tines 7 are arranged in pairs in such a way that they can penetrate the ballast bed 5 on both sides of a track sleeper 8 in order to convey the ballast under the respective track sleeper 8. The tamping tines 7, arranged in pairs, are arranged spaced apart from each other in the longitudinal direction 9 of the rails 6 for this purpose.

[0064] The longitudinal direction 9 is orientated parallel to the rails 6. A transverse direction 10 is orientated horizontally and perpendicular to the longitudinal direction 9. A vertical direction 11 is orientated perpendicular to the longitudinal direction 9 and to the transverse direction 10.

[0065] The device 3 has a running trailer 12 for travelling along the rails 6. The running trailer 12 comprises two bogies 13 and is designed as a trailer without traction drive. Alternatively, the running trailer 12 can have a traction motor to drive it along the rails 6.

[0066] The running trailer 12 has a running trailer carrier 14 with a first support 15a and a second support 15b for supporting on the respective bogie 13.

[0067] The device 3 has a first transverse positioning device 16 and a second transverse positioning device 17. The second transverse positioning device 17 has two transverse positioning parts 18a. 18b that can be displaced linearly to one another. Furthermore, the second transverse positioning device 17 comprises a transverse positioning drive 18c for linear driving of the transverse positioning parts 18a, 18b relative to one another. The first transverse positioning part 18a is attached to the running trailer carrier 14, in particular rigidly. The second transverse positioning part 18b can be displaced relative to the first transverse positioning part 18a along a second transverse positioning direction 18d. The second transverse positioning direction 18d is orientated at an angle, in particular perpendicular, to the track 4 and horizontally, in particular parallel to the transverse direction 10.

[0068] The first transverse positioning device 16 is attached to the second transverse positioning device 17 in such a way that the first transverse positioning device 16 can be displaced linearly at an angle, in particular perpendicular, to the track 4 and horizontally, in particular along the transverse direction 10. The first transverse positioning device 16 has two transverse positioning units 19, 20. The two transverse positioning units 19, 20 are designed identically. Furthermore, the first transverse positioning device 16 comprises a transverse positioning carrier 21 and two transverse positioning-unit drives 22a, 22b. The transverse positioning carrier 21 is attached, in particular rigidly, to the second transverse positioning part 18b of the second transverse positioning device 17. The respective transverse positioning-unit drive 22a, 22b is designed to displace one of the transverse positioning units 19, 20 independently of the other transverse positioning unit 19, 20 along a first transverse positioning direction 23. The first transverse positioning direction 23 is orientated parallel to the second transverse positioning direction 18d and to the transverse direction 10.

[0069] The device 3 has a turning device 24 with two turning units 25, 26. The first turning unit 25 is attached to the first transverse positioning unit 19. The second turning unit 26 is attached to the second transverse positioning unit 20. In particular, the turning device 24 is connected to the first transverse positioning device 16 and the second transverse positioning device 17 in such a way that the turning device 24 can be displaced linearly at an angle, in particular perpendicular, to the track 4 and horizontally, in particular in the transverse direction 10.

[0070] The first turning unit 25 has two turning parts 27a, 27b that can be turned relative to one another. The second turning unit 26 has two turning parts 28a, 28b that can be turned relative to one another. The two turning units 25, 26 each have a turning drive 27c, 28c.

[0071] The turning drives 27c, 28c are designed to drive turning, in particular swivelling, of the respective first turning part 27a, 28a relative to the second turning part 27b, 28b about a respective axis of rotation 27d, 28d. The first turning unit 25, in particular its first turning part 27a, is attached to the first transverse positioning unit 19. The second turning unit 26, in particular its first turning part 28a, is attached to the second transverse positioning unit 20. The two axes of rotation 27d, 28d are orientated vertically, in particular parallel to the vertical direction 11.

[0072] The device 3 has two carrier modules 29, 30. The first carrier module is attached to the first turning unit 25, in particular to the second turning part 27b. The second carrier module 30 is attached to the second turning unit 26, in particular to the second turning part 28b. The carrier modules 29, 30 are designed identically. The carrier modules 29, 30 each comprise two apparatus carriers 31a, 31b for carrying at least one track treatment apparatus 2 and a horizontal positioning device 32 each for displacing the apparatus carriers 31a, 31b in a horizontal direction 33a. 33b, 33c. Furthermore, the horizontal positioning devices 32 comprise horizontal positioning drives 34a. 34b for displacing the apparatus carriers 31a, 31b along the horizontal direction 33a, 33b, 33c.

[0073] The carrier modules 29, 30, in particular the apparatus carriers 31a. 31b, each have a vertical positioning device 35 for displacing the track treatment apparatuses 2 along the vertical direction 11. The vertical positioning devices 35 comprise vertical positioning drives 36a, 36b for automated displacement.

[0074] Preferably, all of the drives 18c, 22a, 22b, 27c, 28c, 34a, 34b, 36a, 36b described above are designed as fluidic drives, in particular as piston-cylinder actuators, in particular as hydraulic cylinders.

[0075] The device 3 has a supporting device 37 for supporting the two carrier modules 29, 30 in the vertical direction 11, in particular in the longitudinal direction 9. The supporting device 37 comprises two support parts 38a. 38b that can be displaced linearly relative to one another. The first support part 38a is attached, in particular rigidly, to the running trailer carrier 14. The second support part 38b can be reversibly attached to the first carrier module 29 or to the second carrier module 30. The first support part 38a comprises two support carriers 39a, 39b. The second support part 38b comprises two linearly shiftable telescopic carriers 40a, 40b, each of which is accommodated in one of the support carriers 39a, 39b.

[0076] The device 3 has a transport lock 41a, 41b for reversible locking of the first transverse positioning device 16 and the second transverse positioning device 17 in a transport position.

[0077] In the transport position, the track treatment system 1, in particular the device 3 and the track treatment apparatuses 2, are arranged completely within a predetermined clearance gauge 42 of the track 4.

[0078] A vertical track centerline plane 43 is orientated parallel to the longitudinal direction 9 and the vertical direction 11 and, with respect to the transverse direction 10, runs centrally between the rails 6 and/or centrally through the device 3, in particular the device 3 arranged in the transport position. A distance x.sub.T1 between the vertical track centerline plane 43 and the first apparatus carrier 31a, in particular its center along the transverse direction 10, is 800 mm in the transport position. The distance x.sub.T1 in a working position is a maximum of 2600 mm. The first apparatus carrier 31a can therefore be displaced by 1800 mm along the transverse direction 10, in particular by means of the transverse positioning devices 16, 17 and the horizontal positioning device 32.

[0079] A distance x.sub.T2 between the vertical track centerline plane 43 and the second apparatus carrier 31b is 650 mm. The second apparatus carrier 31b can also be displaced by 1800 mm along the transverse direction 10.

[0080] A distance x.sub.P between the vertical track centerline plane 43 and an outer contour of the area of the ballast bed 5 that can be treated by means of the tamping tines 7 is 1300 mm in the transport position. In a working position, this distance x.sub.P is a maximum of 3100 mm.

[0081] The turning device 24 and the first transverse positioning device 16, and/or the second transverse positioning device 17, and/or the horizontal positioning device 32 overlap each other at least in sections in a horizontal direction. This allows a particularly low overall construction height H of the device 3 to be achieved.

[0082] The mode of operation of the track treatment system 1, in particular of the device 3, is as follows:

[0083] The running trailer 12 is arranged on the track 4. The track tamping units 2 are attached to the apparatus carriers 31a, 31b, in particular to the respective vertical positioning device 35. The apparatus carriers 31a, 31b are attached to the horizontal positioning device 32 of the respective carrier module 29, 30. The carrier modules 29, 30 are each attached to one of the turning units 25, 26 of the turning device 24. The turning units 25, 26 are each attached to one of the transverse positioning units 19, 20 of the first transverse positioning device 16. The first transverse positioning device 16 is attached to the second transverse positioning device 17, which is attached to the running trailer carrier 14 of the running trailer 12. The device 3 is in the transport position, i.e. completely within the clearance gauge 42. The track treatment system 1, in particular the device 3, is shown in the transport position, in particular in FIG. 10. The transverse positioning devices 16, 17 are locked in the transport position by means of the transport lock 41a. 41b.

[0084] The running trailer 12 is transported to the section of the track 4 to be treated by means of a towing vehicle not shown. The transport lock 41a, 41b is released and the track treatment apparatuses 2 are arranged on the track 4 according to their treatment task, in this case the compaction of the ballast bed 5.

[0085] FIG. 11 shows the track treatment system, in particular the device 3, in a first working position. The respective positioning state of the first transverse positioning device 16 and the turning device 24 is unchanged in relation to the transport position. By means of the transverse positioning drive 18c, the second transverse positioning part 18b is displaced along the second transverse positioning direction 18d relative to the first transverse positioning part 18a. Since all track treatment apparatuses 2, in particular the track treatment apparatuses 2 connected to the two carrier modules 29, 30, can be displaced synchronously by means of the second transverse positioning device 17, the positioning of the track treatment apparatuses 2 in track curves is made possible in a particularly simple manner, in particular one that is easy to control. By means of the horizontal positioning device 32, the track treatment apparatuses 2 are slightly displaced along the respective horizontal direction 33a. By means of the vertical positioning device 35, the track treatment apparatuses 2 are displaced downwards in the vertical direction in relation to the transport position.

[0086] FIG. 12 shows the track treatment system 1, in particular the device 3, in a second working position. In relation to the transport position and in relation to the first working position, the positioning state of the transverse positioning devices 16, 17 of the turning device 24 is changed. Furthermore, the track treatment apparatuses 2 are extended further outwards by means of the horizontal positioning device 32, i.e. Further spaced apart from the vertical track centerline plane 43. In particular, the distances x.sub.P and x.sub.T1 between the vertical track centerline plane 43 and the outer contour of the area of the track 4 that can be treated or the center of the apparatus carrier 31a are maximum. The transverse positioning devices 16, 17 and the horizontal positioning device 32 are maximally extended for this purpose, in particular along the transverse direction 10.

[0087] The track treatment system 1 is arranged in the area of a turnout 44. In addition to the rails 6 on which the running trailer 12, in particular the bogies 13, is arranged, rails 45 of an adjacent track 46 are shown in FIG. 12. A longitudinal direction 47 of the rails 45 is orientated at an angle to the longitudinal direction 9 of the rails 6.

[0088] To treat the rails 45 of the adjacent track 46, the track treatment apparatuses 2 are displaced in the transverse direction 10, in particular relative to the running trailer 12. By means of the first transverse positioning device 16 and the horizontal positioning device 32, the two carrier modules 29, 30 can be displaced independently of one another along the transverse direction 10. This allows the track treatment apparatuses 2, which are attached to the first carrier module 29, to be positioned to treat the adjacent track 46, with the track treatment apparatuses 2, which are attached to the second carrier module 30, being able to be used to treat the track 4.

[0089] The turning devices 24 are designed for rotatory displacement of the two carrier modules 29, 30 independently of each other about the respective axis of rotation 27d, 28d over an angular range of ?=?7? to the transverse direction 10. This allows the track treatment apparatuses 2 of the respective carrier modules 29, 30 to be adapted independently of one another to the orientation, in particular the respective longitudinal direction 9, 47, of the respective track 4, 46, in particular to be aligned according to the respective longitudinal direction 9, 47. In particular, the first carrier module 29 can be orientated according to the longitudinal direction 47 of the adjacent track 46. The second carrier module 30 can be adapted to the local longitudinal direction 9 of the track 4, which can change, in particular relative to the running trailer 12, due to the so-called secant offset. The fact that both carrier modules 29, 30 can be adapted independently of each other to the respective longitudinal direction 9, 47 of the tracks 4, 46 means that the track treatment system 1 is particularly time- and energy-efficient in use and therefore particularly economical in operation.

[0090] By means of the second transverse positioning device 17, all of the track treatment apparatuses 2 can be moved synchronously along the transverse direction 10. A correspondingly synchronous transverse displacement of the track treatment apparatuses 2 is particularly suitable for treating a single track 4. The track treatment apparatuses 2 can be reliably displaced together, in particular, in the area of curves. This makes the track treatment system 1 particularly robust in operation, easy to control, and user-friendly in handling.

[0091] The fact that the device 3 has the first transverse positioning device 16, the second transverse positioning device 17, and/or the horizontal positioning device 32 means that the apparatus carriers 31a, 31b, in particular the track treatment apparatuses 2, can be positioned particularly far away from the vertical track centerline plane 43 in a working position in the transverse direction 10. In the transport position, however, the track treatment system 1, in particular the device 3, does not protrude beyond the specified clearance gauge 42. The device 3 ensures the treatment of tracks 4, 46 in a particularly time-efficient and flexible manner.
