Description

[Technical field]

[0001] The present invention relates to a device for positioning a track treatment tool on a track, and further to a track treatment system comprising such a device. [Background technology]

[0002] From WO 2016 / 149469, a device for positioning a tamping unit on a track is known. The device comprises two support modules with tool carriers for supporting track treatment tools and a rotation device for rotationally displacing both support modules around a respective perpendicular rotation axis. Due to the design of the device, the displacement possibilities of the track treatment tools relative to the track are limited. This has a corresponding limiting effect on the application area of ​​the track treatment tools and on the economics of track treatment.

[0003] Devices for positioning a track treatment tool on a track are furthermore known from DE 40 01 488 A1, DE 20 23 964 A1 and DE 43 13 300 A1. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the invention is to improve a device for positioning a track treatment tool on a track, in particular to provide a device which is particularly flexible in use and which is economical in terms of operation. [Means for solving the problem]

[0005] This problem is solved by a device having the features of claim 1. It has been found that a device for positioning a track treatment tool with at least two support modules and a rotation device for rotationally displacing the at least two support modules can be used in a particularly flexible manner and is economical in terms of operation if the rotation device has at least two rotation units for rotationally displacing the at least two support modules separately and independently of one another. Preferably, the at least two rotation units are rotationally displaceable by the rotation device, each separately and independently of one another, relative to one another and / or relative to the track. The rotation device is preferably formed for rotationally displacing the at least two support modules about a respective rotation axis. The rotation axes are preferably oriented parallel, in particular vertically. The rotation axes may be arranged at a distance from one another. Alternatively, the at least two support modules may be rotationally displaceable about the same rotation axis. Due to the fact that the support modules can be rotated separately and independently of one another, at least one track treatment tool can be positioned on the track in a particularly flexible manner. In particular, the tool carriers of at least two support modules can be adjusted separately and independently of one another in accordance with an orientation that is particularly useful for treating the track. This allows the treatment tool to be positioned flexibly on the track, so that track treatment can be carried out in a particularly time-efficient and economical manner, especially in the area of ​​the switches.

[0006] Such a device allows for a particularly flexible positioning of the at least two support modules, in particular the track processing instrument. The first lateral positioning device is preferably formed for linearly displacing the at least two support modules along one respective first lateral positioning direction. The displacement of the at least two support modules with the first lateral positioning device is preferably performed along the same first lateral positioning direction, in particular in the same first lateral positioning direction, for all support modules. Alternatively, the at least two support modules may be displaceable in mutually different lateral positioning directions. Between the mutually different lateral positioning directions there is preferably an angle in the range of 0°-90°, in particular 1°-75°, in particular 5°-45°, in particular 10°-30°, in particular 15°-20°. The first lateral positioning direction is oriented obliquely to the track and at an 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 at a right angle, in particular at an acute angle, with respect to the longitudinal direction of the track. The acute angle is at most 90°, in particular less than 90°. The at least two support modules are preferably displaceable by the first lateral positioning device over a working stroke in the range of 30 cm to 150 cm, in particular 50 cm to 100 cm.

[0007] The first lateral positioning device is preferably coupled to a running car, in particular a running car carrier, for running on the rail, in particular such that it is rotationally fixed, in particular about the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction, and / or such that it is translationally fixed, in particular about the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction. The first lateral positioning device may be rigidly coupled to the running car, in particular the running car carrier, in terms of rotational and / or translational movements, which allows a particularly precise positioning of the track treatment device.

[0008] "Linearly displacing an object" is preferably understood to mean displacing the object by purely translational motion, in particular along a straight line. For linearly displacing the object, linear guides and / or linear drives may be provided. The linear drives are preferably hydraulic drives, in particular hydraulic cylinders.

[0009] The rotation units are preferably formed for rotationally displacing, in particular pivoting, each support module 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 up to ±180°, in particular up to ±90°, in particular up to ±45°, in particular up to ±20°. The horizontal positioning devices are orientable such that a displacement of the at least one instrument carrier can be effected by each rotation unit, preferably obliquely, in particular perpendicularly, to the longitudinal direction of the track. Preferably, the aforementioned angular ranges are measured starting from a neutral position, i.e. a position in which the horizontal positioning devices can displace the at least one instrument carrier perpendicularly to the longitudinal direction of the track. This allows the instrument carrier to be positioned along the track in a particularly flexible and precise manner.

[0010] By "horizontal direction" is understood a direction which has an angle of at most 25°, in particular at most 10°, in particular at most 5°, in particular at most 2° to the horizontal plane.

[0011] The horizontal positioning device is preferably configured in such a way that it ensures a displacement of the at least one instrument carrier over a working stroke in the range of 30 cm to 120 cm, in particular 50 cm to 100 cm. The horizontal positioning devices of both support modules are preferably configured separately and independently of one another, so that at least one instrument carrier of each support module can be horizontally displaced separately and independently of at least one instrument carrier of the other support module. This is advantageously because the instrument carriers can be positioned on the track in a particularly flexible manner.

[0012] According to one aspect of the invention, each support module has at least two, in particular at least three, in particular at least four tool carriers. Preferably, each support module comprises exactly two support carriers. Each support carrier is preferably formed for supporting at least one, in particular at least two processing tools. This allows the track processing to be performed particularly efficiently and economically.

[0013] According to another aspect of the invention, at least one implement carrier, in particular all implement carriers, comprises a vertical positioning device for linearly displacing the track treatment implement, in particular in a substantially vertical direction, and in particular the vertical positioning device may be configured to penetrate the track treatment implement, in particular a tamping pick of a tamping unit, into the ballast bed of the track.

[0014] "Vertical direction" preferably also includes directions that are not oriented exactly vertically but are oriented substantially vertically, in particular having an angle of at most 15°, in particular at most 10°, in particular at most 5°, in particular at most 2°, in particular at most 1° to a vertically oriented axis.

[0015] According to a further aspect of the invention, the rotary device, in particular the rotary bearing and / or the rotary drive, overlaps the horizontal positioning device, in particular the horizontal guide and / or the horizontal positioning drive, at least to a certain extent in the horizontal direction, so that a particularly small construction height of the device can be obtained.

[0016] "Overlap in a particular direction and / or overlap along a particular direction" is understood to be an overlap that exists in an orthogonal projection onto a projection plane oriented perpendicular to the particular direction.

[0017] According to yet another aspect of the invention, the device has at least two, in particular at least three, in particular at least four support modules. Preferably, the device comprises exactly two support modules.

[0018] Preferably, the device comprises a connection means for mounting the device, in particular on a rail vehicle, which is preferably designed to provide a reversibly detachable connection, for which the connection means may be designed to form a friction-lock connection, in particular a screw connection and / or a form-lock connection.

[0019] According to one aspect of the invention, the device comprises a longitudinal positioning device for linearly displacing at least two support modules, in particular substantially parallel to the longitudinal direction of the rail. Preferably, a first transverse positioning device is attached to the longitudinal positioning device, so that the first transverse positioning device is linearly displaceable along the longitudinal direction of the rail.

[0020] "Two directions oriented parallel to each other" is also understood to mean that the two directions are oriented relative to each other such that there is an angle between the two directions of at most 15°, in particular at most 10°, in particular at most 5°, in particular at most 2°, in particular at most 1°.

[0021] The longitudinal positioning device is preferably connected to a running car, in particular a running car carrier, for running on the rail, in such a way that it is rotationally fixed, in particular rotationally fixed about the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction, and / or translationally fixed, in particular translationally fixed in the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction. The longitudinal positioning device may be connected to the running car, in particular the running car carrier, in a completely rigid manner. This allows the positioning of the track treatment device to be particularly precise.

[0022] The device according to claim 2 allows a particularly flexible positioning of at least two track processing devices. Both support modules are preferably linearly displaceable relative to each other and / or relative to the track by means of a first lateral positioning device. The first lateral positioning device preferably comprises a lateral positioning carrier, on which at least two lateral positioning units are linearly displaceably mounted. Preferably, the first lateral positioning device comprises a telescopic guide. The device is thus specially positionable, in particular in the lateral direction, and thus easy to transport and flexible to use.

[0023] The device according to claim 3 allows a particularly flexible positioning of the at least two track processing devices. The second lateral positioning device is preferably formed for linearly displacing the at least two support modules respectively along a second lateral positioning direction. The lateral positioning directions may be oriented parallel or obliquely to one another. Preferably, the second lateral positioning direction is oriented parallel to the first lateral positioning direction, in particular perpendicular to the longitudinal direction of the track. Preferably, the second lateral positioning device comprises a telescopic guide. This allows the second lateral positioning device to be arranged in a particularly space-saving manner. The second lateral positioning device may be formed for displacing the at least two support modules along a working stroke in the range of 30 cm to 150 cm, in particular 50 cm to 100 cm.

[0024] The second lateral positioning device is preferably connected to a running car, in particular a running car carrier, for running on the rail, in such a way that it is rotationally fixed, in particular rotationally fixed about the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction, and / or translationally fixed, in particular translationally fixed in the vertical direction and / or the rail longitudinal direction and / or the rail transverse direction. The second lateral positioning device may be completely rigidly connected to the running car, in particular the running car carrier. This allows the positioning of the track treatment device to be performed particularly precisely.

[0025] Preferably, the second lateral positioning device is attached to the longitudinal positioning device so that the second lateral positioning device is linearly displaceable along the longitudinal direction of the rail.

[0026] The first and second lateral positioning devices are preferably designed to displace at least two support modules perpendicularly to the longitudinal direction of the track, so that the area of ​​the track that can be treated by the track treatment tool is particularly large, so that the device has a particularly large area of ​​use.

[0027] The device according to claim 4 ensures a particularly flexible positioning of the at least two track processing instruments. The at least two rotating units can be synchronously connected to one another, in particular rigidly connected to one another by the first lateral positioning device and / or the second lateral positioning device, in particular with a fixed distance relative to one another, and / or can be displaceable respectively separately and independently of one another, in particular relative to one another and / or relative to the track. Preferably, the first lateral positioning device and / or the second lateral positioning device are formed in such a way that the distance between the rotation axes of the at least two rotating units is variable.

[0028] The device according to claim 5 is particularly user-friendly and robust in operation. The device is preferably configured in such a way that at least two support modules can be displaced synchronously by the second lateral positioning device. Due to the fact that the first lateral positioning device is attached to the second lateral positioning device, in particular if the first lateral positioning device has at least two lateral positioning units, on which in particular one rotation unit is attached in each case, the at least two support modules can be displaced synchronously by the second lateral positioning device.

[0029] The device according to claim 6 has a particularly low weight, can be arranged particularly compactly and allows access to particularly large processing spaces for track processing. Preferably, the first and second lateral positioning devices, in particular the lateral guides and / or the lateral positioning drives, overlap each other in the horizontal and / or vertical direction at least in a certain section. The first and second lateral positioning devices may overlap each other perpendicularly to the respective lateral positioning direction, in particular over at least 30%, in particular over at least 50%, of their extension along the lateral positioning direction. In particular, the first and second lateral positioning devices may be formed so that they can be telescopically fitted into each other at least in a certain section. More preferably, the linear guides of the first and second lateral positioning devices are spaced apart from each other in the horizontal direction, in particular perpendicularly to the lateral positioning direction.

[0030] The device according to claim 7 ensures a particularly large reach for positioning the track treatment tool laterally of the track. "Displacement perpendicular to the track" is understood to mean displacement perpendicular to the longitudinal extension of the track, in particular in the horizontal direction. Preferably, the first transverse positioning device and / or the second transverse positioning device and / or the horizontal positioning device are designed in such a way that their working strokes add up at least to a certain extent, in particular completely, to displace at least one tool carrier. This allows the track treatment tool to be displaced particularly widely in the direction perpendicular to the longitudinal extension of the track.

[0031] The device according to claim 8 has a particularly high reach for positioning the track treatment tools on the side of the track. Such a device can be used particularly flexibly and economically.

The support device is preferably made for supporting at least one support module, which can be displaced obliquely relative to the track by the first and / or second lateral positioning device, in the vertical direction and / or in the longitudinal direction of the track. By "support" it is understood that at least a part of the weight forces acting on the support module and / or the reaction forces acting on the support module during track processing are removed via the support device. The support device preferably comprises a linear guide, which is displaceable, in particular withdrawable, together with the first and / or second lateral positioning device.

[0033] Preferably, the support device comprises a first support part, in particular at least one support carrier, and a second support part, in particular at least one telescopic carrier, which is linearly displaceably attached to the first support part.

In the transport position, the device is preferably arranged completely within the permissible vehicle contact limits. The device can be arranged in the transport position for a transfer run to the work site.

[0035] The device according to claim 11 ensures a particularly flexible positioning of the track treatment device on the track. The traveling vehicle can be configured as a trailer without its own travel drive or with a travel drive. The travel drive can be configured for moving the traveling vehicle for a transfer trip to the work site and / or for moving the traveling vehicle during track treatment.

[0036] Preferably, the device comprises a control unit for controlling the travelling drive and / or the rotation device and / or the horizontal positioning device and / or the first lateral positioning device and / or the second lateral positioning device and / or the vertical positioning device and / or the at least one track processing device, which advantageously allows the respective displacement movements to be coordinated with one another.

[0062] The vertical track center plane 43 is oriented parallel to the longitudinal direction 9 and the vertical direction 11 and extends in the transverse direction 10 in the middle between the rails 6 and / or through the middle of the device 3, in particular the device 3 arranged in the transport position. The distance x between the vertical track center plane 43 and the first instrument carrier 31a, in particular the center point of the first instrument carrier 31a, along the transverse direction 10 is T1 is 800 mm in the transport position. T1is a maximum of 2600 mm in the working position, i.e. the first instrument carrier 31a can be displaced by 1800 mm along the lateral direction 10, in particular by means of the lateral positioning devices 16, 17 and the horizontal positioning device 32.

[0063] The distance x between the vertical track center plane 43 and the second instrument carrier 31b T2 is 650 mm. The second instrument carrier 31b is also displaceable along the lateral direction 10 by 1800 mm.

[0064] The distance x between the vertical track center plane 43 and the outer contour of the area of ​​the ballast bed 5 that can be processed by the tamping axe 7 P In the transport position, this distance x is 1300 mm. In the working position, P is a maximum of 3100mm.

[0065] The rotating device 24 and the first lateral positioning device 16 and / or the second lateral positioning device 17 and / or the horizontal positioning device 32 overlap one another in the horizontal direction at least to a certain extent, so that a particularly low overall structural height H of the device 3 can be obtained.

[0066] The functional mode of the trajectory processing system 1, and in particular the device 3, is as follows: The traveling vehicle 12 is arranged on the track 4. The track tamping units 2 are mounted on the tool carriers 31a, 31b, in particular on the respective vertical positioning devices 35. The tool carriers 31a, 31b are mounted on the horizontal positioning devices 32 of the respective support modules 29, 30. The support modules 29, 30 are mounted on a respective one of the rotation units 25, 26 of the rotation device 24. The rotation units 25, 26 are mounted on a respective one of the lateral positioning units 19, 20 of the first lateral positioning device 16. The first lateral positioning device 16 is mounted on a second lateral positioning device 17, which is mounted on the traveling vehicle carrier 14 of the traveling vehicle 12. The device 3 is located in the transport position, i.e. completely inside the vehicle contact limit 42. The track handling system 1, in particular the device 3, is shown in particular in the transport position in FIG. 10. The lateral positioning devices 16, 17 are locked in the transport position by transport safety devices 41a, 41b.

[0067] By means of a towing vehicle (not shown), the traveling vehicle 12 is transported to the section of the track 4 to be treated. The transport safety devices 41a, 41b are released and the track treatment tool 2 is positioned on the track 4 in accordance with its treatment task, in this case the compaction of the ballast bed 5.

[0068] In FIG. 11, the track treatment system, in particular the device 3, is shown in a first working position. The respective operating states of the first lateral positioning device 16 and the rotation device 24 remain unchanged relative to the transport position. By means of the lateral positioning drive 18c, the second lateral positioning part 18b is displaced relative to the first lateral positioning part 18a along the second lateral positioning direction 18d. By means of the second lateral positioning device 17, all track treatment devices 2, in particular those connected to both support modules 29, 30, can be displaced synchronously, so that positioning of the track treatment devices 2 in the track curve is possible in a particularly simple and particularly easily controllable manner. By means of the horizontal positioning device 32, the track treatment devices 2 are displaced only slightly along the respective horizontal direction 33a. By means of the vertical positioning device 35, the track treatment devices 2 are displaced downwards in a direction perpendicular to the transport position.

[0069] 12 shows the track handling system 1, in particular the device 3, in a second working position. In contrast to the transport position and in contrast to the first working position, the operating state of the lateral positioning devices 16, 17 and the rotation device 24 has been changed.

[0070] Furthermore, the track processing tool 2 is pulled further outward by the horizontal positioning device 32, i.e. further spaced apart relative to the vertical track center plane 43. In particular, the distance x between the vertical track center plane 43 and the outer contour of the treatable area of ​​the track 4 or the center of the tool carrier 31a is 1 / 2. P and x T1 For this purpose, the lateral positioning devices 16, 17 and the horizontal positioning device 32 are extended to the maximum, in particular along the lateral direction 10.

[0071] The track treatment system 1 is arranged in the area of ​​a switch 44. Next to the rail 6 on which the running vehicles 12, in particular the bogies 13, are arranged, a rail 45 of an adjacent track 46 is shown in Fig. 12. The longitudinal direction 47 of the rail 45 is oriented obliquely with respect to the longitudinal direction 9 of the rail 6.

[0072] In order to treat the rails 45 of the adjacent track 46, the track treatment tool 2 is displaced in the lateral direction 10, in particular relative to the traveling vehicle 12. By means of the first lateral positioning device 16 and the horizontal positioning device 32, both support modules 29, 30 can be displaced along the lateral direction 10 separately and independently of one another. This allows the track treatment tool 2 attached to the first support module 29 to be positioned for treating the adjacent track 46. In this case, the track treatment tool 2 attached to the second support module 30 can be used for treating the track 4.

[0073] The rotation device 24 is designed for displacing the two support modules 29, 30 in a rotational manner separately and independently of one another about the respective rotation axis 27d, 28d in an angular range of α=±7° relative to the transverse direction 10. This allows the track treatment device 2 of each support module 29, 30 to be adapted separately and independently of one another to the orientation of the respective track 4, 46, in particular to the respective longitudinal direction 9, 47, and to be positioned in accordance with the respective longitudinal direction 9, 47. In particular, the first support module 29 can be oriented in accordance with 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 vary based on the so-called secant offset, in particular with respect to the vehicle 12. Due to the fact that both support modules 29, 30 can be adapted to the respective longitudinal directions 9, 47 of the tracks 4, 46 separately and independently of one another, the track handling system 1 is efficient in use, in particular in terms of time and energy, and therefore particularly economical in operation.

[0074] By means of the second lateral positioning device 17, all the track processing tools 2 can be displaced synchronously along the lateral direction 10. The correspondingly synchronous lateral displacement of the track processing tools 2 is particularly suitable for processing a single track 4. In particular in the region of curves, the track processing tools 2 can be reliably displaced together. This makes the track processing system 1 particularly robust in operation, easily controllable and user-friendly in terms of handling.

[0075] Due to the fact that the device 3 has the first lateral positioning device 16, the second lateral positioning device 17 and / or the horizontal positioning device 32, the tool carriers 31a, 31b, in particular the track processing tool 2, can be positioned in the lateral direction 10 in the working position at a particularly large distance from the vertical track centre plane 43. In the transport position, however, the track processing system 1, in particular the device 3, does not protrude beyond a predefined vehicle contact limit 42. The device 3 ensures a particularly time-efficient and flexible processing of the track 4, 46.
