The invention relates to a device for positioning track treatment apparatuses on the track. The invention also relates to a track treatment system with such a device.
A device for positioning tamping units on the track is known from WO 2016/149 469 A1. The device comprises two carrier modules with apparatus carriers for carrying the track treatment apparatuses and a turning device for rotatory displacement of the two carrier modules about a vertical axis of rotation each. Due to the design of the device, there are limits to how far the track treatment apparatuses can be displaced relative to the track. This has correspondingly limiting effects on their area of application and the cost-effectiveness of track treatment.
Devices for positioning track treatment apparatuses on the track are also known from DE 4001488 A1, DE 2023964 B2 and DE 4313300 A1.
It is an object of the invention to create an improved device for positioning track treatment apparatuses on the track which is, in particular, particularly flexible in use and economical in operation.
This object is achieved by way of a device with the features of claim 1. It has been recognized that a device for positioning track treatment apparatuses on the track with at least two carrier modules and a turning device for rotatory displacement of the at least two carrier modules can be used particularly flexibly and is economical in operation if the turning device has at least two turning units for rotatory displacement of the at least two carrier modules independently of each other. Preferably, the at least two turning units can each be displaced rotatorily relative to one another and/or relative to the track independently of one another by means of the turning device. The turning device is preferably designed for rotatory displacement of the at least two carrier modules about an axis of rotation each. The axes of rotation are preferably orientated parallel, in particular vertically. The axes of rotation can be arranged spaced apart from each other. Alternatively, the at least two carrier modules can be displaced rotatorily about the same axis of rotation. The fact that the carrier modules can be rotated independently of each other means that the at least one track treatment apparatus can be positioned on the track particularly flexibly. In particular, the apparatus carriers of the at least two carrier modules can be aligned independently of each other according to an orientation that is particularly favourable for treating the track. This allows the treatment apparatuses to be positioned flexibly on the track, making the track treatment particularly time-efficient and economical, in particular, in the area of turnouts.
Such a device enables the positioning of the at least two carrier modules, in particular the track treatment apparatuses, in a particularly flexible manner. The first transverse positioning device is preferably designed for linear displacement of the at least two carrier modules along a horizontal direction. The displacement of the at least two carrier modules by means of the first transverse positioning device is preferably carried out for all carrier modules in the same first transverse positioning direction. Alternatively, the at least two carrier modules can be displaced in different transverse positioning directions.
Between the different transverse positioning devices there is an angle in a range of 0° to 90°, in particular of 10 to 75°, in particular of 5° to 45°, in particular of 10° to 30°, in particular of 15° to 20°. The first transverse positioning direction is orientated at an angle to the track, in particular at 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 carrier modules can preferably be displaced by means of the first transverse positioning device via an actuating path in the range from 30 cm to 150 cm, in particular from 50 cm to 100 cm.
The first transverse positioning device is connected in particular torque proofed, in particular about a vertical direction, and/or a longitudinal direction of the rail, and/or a transverse direction of the rail, and/or translative proofed in particular in vertical direction, and/or in longitudinal direction of the rail, and/or in transverse direction of the rail, with a running trailer for travelling along rails in particular with a running trailer carrier. The first transverse positioning device can be connected rotatory and/or translative fixed with the running trailer in particular with the running trailer carrier. This allows the treatment apparatuses to be positioned particularly precisely.
Linear displacement of an object means the exclusive translative displacement of the object, in particular along a straight line. For the linear displacement of the object can be provided a linear guide and/or a linear drive. The linear drive is in particular a hydraulic drive, in particular a hydraulic cylinder.
The turning units are preferably designed for rotatory displacement, in particular for swivelling the respective carrier modules, over an angular range of at least ±5°, in particular at least ±7°, in particular at least ±10°, in particular at least ±20°, in particular at least ±45°, in particular at least ±90°, and/or a maximum of ±180°, in particular a maximum of ±90°, in particular a maximum of ±45°, in particular a maximum of ±20°. The horizontal positioning device can preferably be orientated by means of the respective turning unit in such a way that the displacement of the at least one apparatus carrier can take place at an angle in one direction, in particular perpendicular to a longitudinal direction of the track. Preferably, the aforementioned angular ranges are measured starting from a neutral position in which the horizontal positioning device can displace the at least one apparatus carrier in a direction perpendicular to the longitudinal direction of the track. This allows the apparatus carriers to be aligned particularly flexibly and precisely along the track.

The horizontal positioning device is preferably designed in such a way that it ensures the displacement of the at least one apparatus carrier over an actuating path in the range from 30 cm to 120 cm, in particular from 50 cm to 100 cm. The horizontal positioning devices of the two carrier modules are preferably designed independently of each other so that the at least one apparatus carrier of the respective carrier module can be displaced in the horizontal direction independently of the at least one apparatus carrier of the other carrier module. Advantageously, this enables the apparatus carriers to be positioned particularly flexibly on the track.

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.
The mode of operation of the track treatment system 1, in particular of the device 3, is as follows:
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
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.
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
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.
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 α=±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.
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.
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.
