[0001] The invention relates to a device for positioning track maintenance equipment on the track. Furthermore, the invention relates to a track maintenance system with such a device.

[0002] WO 2016 / 149 469 A1 discloses a device for positioning tamping units on the track. The device comprises two support modules with tool carriers for supporting the track maintenance equipment and a rotating device for rotating the two support modules around a vertical axis of rotation. The design of the device limits the ability of the track maintenance equipment to move relative to the track. This has correspondingly limiting effects on their area of ​​application and the cost-effectiveness of track maintenance.

[0003] Devices for positioning track maintenance equipment on the track are also known from DE 4001488 A1, DE 2023964 B2 and DE 4313300 A1.

[0004] It is an object of the invention to provide an improved device for positioning track maintenance equipment on the track, which is particularly flexible in use and economical in operation.

[0005] This object is achieved by a device having the features of claim 1. It has been recognized that a device for positioning track maintenance equipment on the track with at least two support modules and a rotating device for the rotational displacement of the at least two support modules can be used particularly flexibly and is economical in operation if the rotating device has at least two rotating units for the independent rotational displacement of the at least two support modules. Preferably, the at least two rotating units can be rotated independently of one another relative to one another and / or relative to the track by means of the rotating device. The rotating device is preferably designed for the rotational displacement of the at least two support modules about a respective rotational axis. The rotational axes are preferably oriented parallel, in particular vertically. The rotational axes can be arranged at a distance from one another.Alternatively, the at least two support modules can be rotatably displaced around the same axis of rotation. Because the support modules can rotate independently of one another, the at least one track maintenance device can be positioned particularly flexibly on the track. In particular, the device carriers of the at least two support modules can be aligned independently of one another according to an orientation that is particularly conducive to track maintenance. This allows the maintenance devices to be positioned flexibly on the track, making track maintenance, particularly time-efficient and cost-effective, particularly in the area of ​​switches.

[0006] Such a device enables the positioning of the at least two support modules, in particular the track maintenance devices, in a particularly flexible manner. The first transverse positioning device is preferably designed for the linear displacement of the at least two support modules along a respective first transverse positioning direction. The displacement of the at least two support modules by means of the first transverse positioning device preferably takes place for all support modules along the same, in particular in the same, first transverse positioning direction. Alternatively, the at least two support modules can be displaceable in different transverse positioning directions. Between the different transverse positioning directions there is preferably an angle in a range from 0° to 90°, in particular from 1° to 75°, in particular from 5° to 45°, in particular from 10° to 30°, in particular from 15° to 20°.The first transverse positioning direction is oriented obliquely to the track, specifically at an angle, in particular an acute angle, of at least 30°, in particular at least 45°, in particular at least 60°, in particular at least 75°, in particular at least 85°, in particular perpendicular to the longitudinal direction of the track. An acute angle is a maximum of 90°, in particular less than 90°. The at least two support modules can preferably be displaced by means of the first transverse positioning device over a travel range in the range of 30 cm to 150 cm, in particular from 50 cm to 100 cm.

The horizontal positioning devices of the two support modules are preferably designed independently of one another, so that the at least one equipment carrier of the respective support module can be displaced in the horizontal direction independently of the at least one equipment carrier of the other support module.

The support modules 29, 30 are each attached to one of the rotating units 25, 26 of the rotating device 24. The rotating 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 fastened to the carriage carrier 14 of the carriage 12. The device 3 is in the transport position, i.e., completely within the clearance profile 42.The track processing system 1, in particular the device 3, is shown in particular in the . Fig. 10 shown in the transport position. The transverse positioning devices 16, 17 are locked in the transport position by means of the transport lock 41a, 41b.

[0066] By means of a tractor (not shown), the carriage 12 is transported to the section of track 4 to be processed. The transport lock 41a, 41b is released, and the track processing devices 2 are arranged on the track 4 according to their processing task, in this case the compaction of the ballast bed 5.

[0067] In the Fig. 11 The track maintenance system, in particular the device 3, is shown in a first working position. The respective setting state of the first transverse positioning device 16 and the rotating device 24 is unchanged compared 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 maintenance devices 2, in particular the track maintenance devices 2 connected to the two support modules 29, 30, can be displaced synchronously by means of the second transverse positioning device 17, the positioning of the track maintenance devices 2 in track curves is made possible in a particularly simple, in particular easy-to-control, manner. By means of the horizontal positioning device 32, the track maintenance devices 2 are displaced slightly along the respective horizontal direction 33a.By means of the vertical positioning device 35, the track processing devices 2 are displaced vertically downwards relative to the transport position.

[0068] In the Fig. 12 The track processing system 1, in particular the device 3, is shown in a second working position. Compared to the transport position and the first working position, the setting state of the transverse positioning devices 16, 17 of the rotating device 24 is changed.

[0069] Furthermore, the track processing devices 2 are extended further outward by means of the horizontal positioning device 32, i.e., further away from the vertical track center plane 43. In particular, the distances x P and x T1 between the vertical track center plane 43 and the outer contour of the processable area of ​​the track 4 or the center of the device carrier 31a are at their maximum. For this purpose, the transverse positioning devices 16, 17 and the horizontal positioning device 32 are extended to their maximum extent, in particular along the transverse direction 10.

[0070] The track processing system 1 is arranged in the area of ​​a switch 44. In addition to the rails 6, on which the carriage 12, in particular the bogies 13, are arranged, Fig. 12 Rails 45 of an adjacent track 46 are shown. A longitudinal direction 47 of the rails 45 is oriented obliquely to the longitudinal direction 9 of the rails 6.

[0071] To machine the rails 45 of the adjacent track 46, the track processing devices 2 are displaced in the transverse direction 10, in particular relative to the carriage 12. By means of the first transverse positioning device 16 and the horizontal positioning device 32, the two support modules 29, 30 can be displaced independently of one another along the transverse direction 10. As a result, the track processing devices 2, which are attached to the first support module 29, can be positioned for machining the adjacent track 46, while the track processing devices 2, which are attached to the second support module 30, can be used for machining track 4.

[0072] The rotating devices 24 are designed for the independent rotational displacement of the two support modules 29, 30 about the respective rotational axis 27d, 28d over an angular range of α = ±7° to the transverse direction 10. As a result, the track maintenance devices 2 of the respective support modules 29, 30 can 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 aligned according to the respective longitudinal direction 9, 47. In particular, the first support module 29 can be oriented according to the longitudinal direction 47 of the adjacent track 46. The second support module 30 can be adapted to the local longitudinal direction 9 of the track 4, which can change, in particular relative to the carriage 12, due to the so-called secant offset.Because both support modules 29, 30 can be adapted independently of each other to the respective longitudinal direction 9, 47 of the tracks 4, 46, the track processing system 1 is particularly time and energy efficient in use and thus particularly economical in operation.

[0073] By means of the second transverse positioning device 17, all of the track maintenance devices 2 can be moved synchronously along the transverse direction 10. Such synchronous transverse movement of the track maintenance devices 2 is particularly suitable for the processing of a single track 4. Especially in the area of ​​curves, the track maintenance devices 2 can be reliably moved together. This makes the track maintenance system 1 particularly robust in operation, easy to control, and user-friendly.

[0074] Because the device 3 has the first transverse positioning device 16, the second transverse positioning device 17, and / or the horizontal positioning device 32, the equipment carriers 31a, 31b, in particular the track maintenance devices 2, can be positioned particularly far away from the vertical track center plane 43 in a working position in the transverse direction 10. In the transport position, however, the track maintenance system 1, in particular the device 3, does not protrude beyond the specified clearance profile 42. The device 3 ensures the maintenance of tracks 4, 46 in a particularly time-efficient and flexible manner.
