DETAILED DESCRIPTION OF THE INVENTION

[0046] A first embodiment of the invention is described below with reference to FIGS. 1 to 3. A processing device 1 for performing track work comprises a rail-mounted flat car 2 to which a processing system 3 is fastened. The flat car 2 comprises a chassis 4 on which a plurality of axles with wheels 5 attached thereto are rotatably mounted. The wheels 5 are guided on rails 6 of a track system 7. The processing device 1 is coupled to a rail vehicle 8 in the transport state shown in FIG. 1. The rail vehicle 8 can be operated electrically and is supplied with electric energy via an overhead line 9 of the track system 7.

[0047] The processing system 3 comprises a first enclosure 10 and a second enclosure 11. The enclosures 10, 11 are designed as standard containers or ISO containers. The enclosures 10, 11 each have an underside S.sub.U, an upper side S.sub.O, two opposite long sides S.sub.L, S.sub.R and two opposite short sides S.sub.V, S.sub.H. The underside S.sub.U, the upper side S.sub.O and the sides S.sub.L, S.sub.R and S.sub.V are configured by solid walls 12, whereas the side S.sub.H is configured by a covering element 13 in the form of a two-part door. The covering element 13 is displaceable relative to the walls 12. The covering element 13 may be opened or closed so that the covering element 13 exposes or closes an enclosure opening 14.

[0048] The enclosures 10, 11 have a length L, a width B and a height H. For the length L: 280 cm≤L≤1,700 cm, in particular cm 500≤L≤1,300 cm, and in particular 600 cm≤L≤610 cm. For the width B: 100 cm≤B≤300 cm, in particular 200 cm≤B≤280 cm, and in particular 240 cm≤B≤250 cm. For the height H, 100 cm≤H≤300 cm, in particular 180 cm≤H≤290 cm, and in particular 250 cm≤H≤280 cm. The first enclosure 10 bounds a first interior space 15. Correspondingly, the second enclosure 11 bounds a second interior space 16. The enclosures 10, 11, in the region of the underside Su, have a plurality of fastening elements 19 which interact with counter-fastening elements of the flat wagon 2 for fastening to the chassis 4. The counter-fastening elements are not shown in more detail.

[0049] The processing system 3 comprises a multi-axis robot 17 and an associated displacement device 18 for performing track work. The multi-axis robot 17 is arranged at the displacement device 18 such that the multi-axis robot 17 can be displaced from a transport position in the interior space 15 through the open enclosure opening 14 to a working position outside the interior space 15.

[0050] The multi-axis robot 17 is designed as an industrial robot. The multi-axis robot 17 has six movement axes, which are designated in detail as B.sub.1 to B.sub.6. The design of the multi-axis robot 17 is known and usual.

[0051] The displacement device 18 comprises a guide 20 and a mounting element 21 configured as a slide. The guide 20 is fastened to the enclosure 10 in the interior space 15 in the region of the underside S.sub.U. The guide 20 is arranged adjacent to the enclosure opening 14. The guide 20 is designed as a linear guide. The displacement device 18 thus has a linear axis x. The mounting element 21 can be displaced along the linear axis x on the guide 20 by means of a drive which is not shown in greater detail. The mounting element 21 is L-shaped in cross-section and has a long leg and a short leg. In the region of the long leg, the mounting element 21 is mounted on the guide 20, whereas the short leg extends essentially perpendicularly to the long leg and the guide 20. In the region of the short leg, the multi-axis robot 17 is fastened to the mounting element 21 in a substantially horizontal position.

[0052] The multi-axis robot 17 and the displacement device 18 are in a transport position in the transport state of the processing device 1 shown in FIG. 1. In the transport position, the multi-axis robot 17 and the displacement device 18 are arranged completely in the interior space 15, so that the enclosure 10 can be closed by means of the covering element 13. The displacement device 18 can be locked in the transport position.

[0053] The processing system 3 further comprises a tool magazine 22 with an associated tool changer 23 for performing an automatic tool change and a control unit 24. The tool magazine 22 and the tool changer 23 are arranged in the interior space 15. The tool magazine 22 is fastened to the enclosure 10 in the region of the underside S.sub.U. On the other hand, the tool changer 23 is arranged on a tool changer slide 25, which is arranged in a linearly displaceable manner on the mounting element 21. The tool changer 23 is linearly displaceable in the direction of the linear axis x between the tool magazine 22 and the multi-axis robot 17 by means of a drive not shown in more detail.

[0054] The processing system 3 further comprises an energy generator 26 and an energy storage 27 for providing electric energy. The energy generator 26 and the energy storage 27 are arranged in the interior space 16 of the second enclosure 11. The energy generator 26 comprises, for example, a power unit having a drive operable by means of a fuel and a power generator driven thereby. The energy storage 27 is designed, for example, as an accumulator.

[0055] The first enclosure 10 has a first connection 28 and the second enclosure 11 has a second connection 29 for transmitting electric energy. The connections 28, 29 are connected to each other via a supply line 30, so that the part of the processing system 3 arranged in the enclosure 10 is supplied with electric energy. An external supply line may alternatively be connected to the connection 28, so that an external power supply is made possible. In this case, the enclosure 11 with the energy generator 26 and the energy storage 27 is not required.

[0056] For controlling the multi-axis robot 17 and for monitoring a working space A of the multi-axis robot 17, the processing system 3 has sensors 31, 32, 33. A first sensor 31 is configured as a camera. The first sensor 31 is arranged in the region of a tool receptacle 34 of the multi-axis robot 17. A second sensor 32 and a third sensor 33 are designed as a camera. The sensors 32, 33 are arranged in the region of the enclosure opening 14 in the interior space 15 of the enclosure 10. The sensors 31, 32, 33 are in signal communication with the control unit 24.

[0057] To protect a working space A from environmental influences, the processing system 3 has a protective element 35. The working space A is defined by the movement range of the multi-axis robot 17. The protective element 35 is plate-shaped and is mounted in a linearly displaceable manner on the enclosure 10 in the region of the upper side So. The protective element 35 can be displaced manually or by means of a drive.

[0058] FIG. 3 shows the processing system 3 at a place of use or at a track location to be processed in a working state. The multi-axis robot 17 and the displacement device 18 are in a working position. The displacement device 18 is lockable in the working position. In the working position, the multi-axis robot 17 is no longer in the interior space 15, but in an exterior space of the enclosure 10.

[0059] The operating principle of the processing device 1 is described below:

[0060] Initially, the processing device 1 is in the transport state shown in FIG. 1. The multi-axis robot 17 and the displacement device 18 as well as the protective element 35 are arranged completely inside the enclosure 10. The enclosures 10, 11 are closed by means of the respective covering element 13. In the transport state, the processing system 3 externally appears as two enclosures 10, 11.

[0061] The processing device 1 is coupled to the rail vehicle 8 and is transported by means of same to a desired place of use or a track location to be processed. At the place of use, the processing device 1 or processing system 3 is transferred from the transport state to the working state shown in FIG. 3. For this purpose, the covering element 13 of the enclosure 10 is first opened. The mounting element 21 is moved linearly on the guide 20 along the linear axis x, so that the displacement device 18 is transferred from a transport position to a working position. The displacement device 18 is locked in the working position. The multi-axis robot 17 fastened to the mounting element 21 is correspondingly transferred from a transport position to a working position. In the working position, the multi-axis robot 17 is located outside the enclosure 10. The protective element 35 is linearly displaced in the working position so that it at least partially shields the working space A.

[0062] The multi-axis robot 17 may now be used to perform track work, for example to process the rails 6. For this purpose, a tool not shown in more detail is located in the tool receptacle 34. The first sensor 31 detects, for example, the rail 6 to be processed, so that the multi-axis robot 17 may be controlled in the desired manner by means of the control unit 24. The sensors 32, 33 monitor the working space A. If, for example, a person enters the working space A, this is detected by the sensors 32, 33 and recognized by the control unit 24, so that the control unit 24 stops the multi-axis robot 17.

[0063] When a tool change is required, the tool changer 23 takes the required tool from the tool magazine 22. The tool changer 23 is then moved linearly in the direction of the multi-axis robot 17 by means of the tool changer slide 25. The multi-axis robot 17 deposits the tool that is no longer required in the tool changer 23 and removes the required tool from the tool changer 23. The multi-axis robot 17 can then continue processing. The tool changer 23 is again moved linearly in the direction of the tool magazine 22 and deposits the tool that is no longer required in the tool magazine 22.

[0064] When the track work is completed, the multi-axis robot 17 and the displacement device 18 are moved back to the transport position. The displacement device 18 is locked in the transport position. The protective element 35 is displaced into the enclosure 10. Subsequently, the covering element 13 of the enclosure 10 is closed so that the enclosure opening 14 is closed. The processing device 1 may now be transported away by means of the rail vehicle 8.

[0065] A second embodiment of the invention is described below with reference to FIG. 4. In contrast to the first embodiment, the displacement device 18 additionally has a swivel axis 36 for swiveling the multi-axis robot 17. The multi-axis robot 17 can be swiveled about the horizontally extending swivel axis 36, so that the multi-axis robot 17 is swiveled from a horizontal position to a vertical position. By swiveling about the swivel axis 36, the movement axis Bi may thus be transferred from the horizontal position shown in FIG. 4 to a vertical position. For this purpose, the mounting element 21 is designed as a swivel bridge. The mounting element 21 is part of the displacement device 18 and is mounted in a swiveling manner on the slide 37 of the displacement device 18. By swiveling into a vertical position, the multi-axis robot 17 may reach the overhead line 9. This allows maintenance and/or inspection work to be carried out on the overhead line 9. With regard to the further structure and the further operating principle, reference is made to the first embodiment.

[0066] A third embodiment of the invention is described below with reference to FIG. 5. In contrast to the preceding embodiments, the processing system 3 has a dry ice supply unit 38. The dry ice supply unit 38 comprises a CO.sub.2 storage enclosure 39, a pelletizer 40, a dry ice storage enclosure 41, a compressed air generator 42, and a proportioner 43. The CO.sub.2 storage enclosure 39 is fastened in the enclosure 10. The pelletizer 40, the dry ice storage enclosure 41, the compressed air generator 42 and the proportioner 43 are fastened to the mounting element 21, which is designed as a slide. The pelletizer 40 is supplied with liquid CO.sub.2 from the CO.sub.2 storage enclosure 39 via a supply line and produces dry ice pellets, which are stored in the dry ice storage enclosure 41. The compressed air generator 42 provides compressed air so that a dry ice-compressed air mixture is provided by means of the proportioner 43. The dry ice supply unit 38 further comprises a treatment nozzle 44 which is arranged in the tool receptacle 34 and guided by means of the multi-axis robot 17. The treatment nozzle 44 is connected with the proportioner 43 via a mixture line 45. The mixture line 45 is designed as a flexible tube. In particular, the mixture line 45 is mounted so that it can be rolled up and unrolled and can thus be flexibly adapted to the movement of the multi-axis robot 17. By means of the treatment nozzle 44, the dry ice-compressed air mixture may be discharged for the treatment of surfaces. With regard to the further structure and the further operating principle, reference is made to the preceding embodiments.

[0067] A fourth embodiment of the invention is described below with reference to FIGS. 6 to 10. The processing system 3 comprises a first multi-axis robot 17 for grinding and/or milling the rails 6 and a second multi-axis robot 17′ for welding, in particular for buildup welding and/or joint welding.

[0068] The mounting element 21 is formed as a cuboid frame. The mounting element 21 comprises longitudinal struts 46 running in an x-direction, transverse struts 47 running in a y-direction and vertical struts 48 running in a z-direction. The x-direction, the y-direction and the z-direction run perpendicularly to each other in pairs and form a Cartesian coordinate system. The guide 20 is designed as a linear guide. The guide has a cuboid base frame 49, which is fastened to the enclosure 10 in the interior space 15. Guide elements 50 for linear guiding of the mounting element 21 are arranged on the base frame 49 on the upper side S.sub.O and on the underside S.sub.U. The guide elements 50 are designed, for example, as guide rollers. For linear displacement of the mounting element 21, the guide elements 50 can be driven in rotation, for example, by means of a drive not shown in more detail.

[0069] The mounting element 21 delimits an interior space 51 in which the multi-axis robots 17, 17′ are arranged. The first multi-axis robot 17 is suspended from the mounting element 21. For this purpose, the mounting element 21 forms a mounting plane E.sub.1 running parallel to an x-y plane. The first movement axis B.sub.1 of the multi-axis robot 17 runs perpendicularly to the mounting plane E.sub.1.

[0070] The second multi-axis robot 17′ is arranged in the x-direction between the first multi-axis robot 17 and the short side S.sub.V of the enclosure 10. The second multi-axis robot 17′ is fastened to a linear guide 52 and can be displaced linearly in a plane E.sub.2 by means of the latter. The plane E.sub.2 encloses an angle a with the plane E.sub.1, where: 0°<α≤90°. The second multi-axis robot 17′ has six movement axes B.sub.1 to B.sub.6 corresponding to the first multi-axis robot 17.

[0071] For processing a rail 6, a grinding tool and/or a milling tool is accommodated in the tool receptacle 34 of the first multi-axis robot 17. In order to perform a tool change, the tool magazine 22 is fastened to the mounting element 21.

[0072] A welding head is arranged in the tool receptacle 34 of the second multi-axis robot 17′. The welding head is part of a welding device 53 that is fastened to the mounting element 21.

[0073] For supporting in the working position, the displacement device 18 comprises supporting elements 54. The mounting element 21 comprises a first end which is disposed away from the enclosure 10 in the working position and a second end remaining within the enclosure 10 in the working position. The supporting elements 54 are arranged at the first end. The supporting elements 54 are displaceable in the z-direction relative to the mounting element 21. The supporting elements 54 are retractable and extendable, for example, by means of a drive not shown in more detail. In a retracted transport position, the supporting elements 54 are arranged in the interior space 51. In an extended working position, the supporting elements 54 are arranged outside the interior space 51. The supporting elements 54 each comprise a carrier 55 and a guide roller 56 arranged on the carrier 55. By means of the guide roller 56, the mounting element 21 can be supported at the first end on a respective rail 6. The guide rollers 56 have axes of rotation running parallel to the y-direction and center the mounting element 21 relative to the rails 6.

[0074] A plurality of protective elements 35 are arranged at the displacement device 18 to protect the working space A. Protective elements 35 are arranged on the mounting element 21 on the long sides, on the upper side and on the short side that forms the first end. The protective elements 35 are merely indicated in FIGS. 6 to 10. The protective elements 35 are, for example, configured as to be foil-like and are opaque, so that no persons outside the working space A are endangered by the welding in the working space A. Furthermore, a protective element 35 is arranged between the supporting elements 54. This protective element 35 is extended and retracted with the supporting elements 54.

[0075] To laterally delimit the working space A between the mounting element 21 and the track, frame components 57 are arranged laterally on the mounting element 21 so as to be swiveled about swivel axes S.sub.1 and S.sub.2. The frame components 57 are U-shaped. Further protective elements 35 are arranged on the frame components 57.

[0076] In the transport state shown in FIG. 6, the multi-axis robots 17, 17′ are arranged in the interior space 51 of the cuboid mounting element 21. For this purpose, the linear guide 52 is in a retracted transport state. Furthermore, the movement axes B.sub.1 to B.sub.6 are displaced such that the multi-axis robots 17, 17′ take a compact transport position within the interior space 51. The supporting elements 54 are retracted and arranged within the interior space 51. The frame components 57 are swiveled in. The mounting element 21 is displaced into the interior space 15 of the enclosure 10, so that the displacement device 18 with the multi-axis robots 17, 17′ arranged thereon is completely disposed in the interior space 15 of the enclosure 10.

[0077] For transferring the processing system 3 to the working state, the covering elements 13, which are designed as doors, are opened so that the enclosure opening 14, which is arranged on the short side S.sub.H, is open.

[0078] The mounting element 21 is moved linearly out of the enclosure 10 by means of the guide 20. The supporting elements 54 are extended from the interior space 51 until the guide rollers 56 are arranged on the rails 6. The supporting elements 54 support the mounting element 21 during the extension and in the working state. During the extension, the guide rollers 56 guide the first end of the mounting element 21. For this purpose, the guide rollers 56 roll on the rails 6. FIG. 7 shows the processing system 3 during the extension.

[0079] When the mounting element 21 is fully extended, the working space A is delimited or shielded. The working space A is formed by the inner space 51 and the space between the mounting element 21 and the track. The mounting element 21 is already shielded by means of the protective elements 35 on the long sides, on the upper side and on the extended short side. By extending the supporting elements 54, the region between the first end and the track is shielded. In order to shield the lateral regions, the frame components 57 are swiveled about the swivel axes S.sub.1 and S.sub.2. The swiveling may be performed manually and/or automatically. FIG. 8 shows the processing system 3 during the swiveling out of the frame components 57 with the protective elements 35.

[0080] In FIGS. 9 and 10, the processing system 3 is shown in the working state. After the working space A has been shielded on all sides, the performance of the track work begins. By means of the first multi-axis robot 17, a rail 6 to be processed is prepared for buildup welding and/or joint welding, for example by milling processing or grinding processing. Subsequently, the welding process is carried out by means of the second multi-axis robot 17′. The supporting elements 54 support the first end of the mounting element 21 while the track work is being performed, so that the multi-axis robots 17, 17′ are mounted on the mounting element 21 with little or no vibration. As a result, the track work may be performed accurately and reliably.

[0081] The transfer of the processing system 3 from the working state to the transport state takes place in the reverse manner. With regard to the further structure and the further operating principle, reference is made to the preceding embodiments.

[0082] In general:

[0083] There is considerable potential for automation in the maintenance of rail infrastructure. The existing rail infrastructure is suitable for transporting automated maintenance solutions to the place of use. Up to now, maintenance work has been carried out mainly by hand with the aid of hand-guided tools. The maintenance work or track work has a high manual component and is physically strenuous for workers. Further, workers are exposed to environmental influences and dangers.

[0084] The processing system according to the invention comprises an enclosure, preferably with dimensions and/or interfaces according to ISO standard and with an integrated multi-axis robot. Preferably, the processing system comprises a tool magazine, a control unit and/or its own power supply. The processing system may be transported on standardized means of transport, such as a truck, a rail car and/or a container ship, and thus be brought to the place of use. During the transport, the multi-axis robot is protected from environmental influences in the closed enclosure. At the place of use, the enclosure may be parked in a fixed location or fastened to a trolley so that it can be displaced flexibly with little effort. For example, the enclosure may have its own drive for locomotion. The enclosure may, for example, be connected to a crawler chassis or a chassis similar to a walking excavator. At the place of use, the multi-axis robot is displaced from the container to perform maintenance operations and track work on the railroad infrastructure. For displacement, the multi-axis robot is arranged on a displacement device. The displacement device comprises, for example, a linear guide with a drive. For transport, the displacement device may be locked in a transport position.

[0085] For performing track work, the processing system preferably comprises a tool magazine with tools and equipment required for the respective application and, if necessary, a tool changing system. In addition, the processing system may include a material store.

[0086] The energy supply of the processing system is either provided by supplying electric energy from outside via a connection or via its own energy supply.

[0087] The multi-axis robot can perform work above head height, for example on overhead lines or overhead line masts, as well as work on the ground, for example on tracks or objects close to the ground. Furthermore, the multi-axis robot can perform work to the side of the tracks, for example on noise barriers.

[0088] The displacement device may be designed differently as required and may enable the multi-axis robot to move, rotate and/or lift.

[0089] In particular, the processing system includes sensors and a controller suitable for moving the multi-axis robot into a suitable position to perform the desired maintenance operations.

[0090] By installing a multi-axis robot in an enclosure according to ISO standards or in an ISO container, simplified rail network access conditions and approval conditions for use and transport on the track apply. As a result, the processing system can be used easily and flexibly.

[0091] In particular, the displacement device enables a slide to which the multi-axis robot is fastened to be moved beyond the buffer chest of a freight car or flat car. If required, the displacement device enables a tilting and/or a rotation.

[0092] The displacement device comprises at least one linear axis, for example a linear axis in longitudinal direction and/or a linear axis in transverse direction and/or a linear axis in vertical direction of the enclosure. The displacement device may be fastened to the enclosure at an underside, an upper side and/or one of the long sides. A safety device may be provided in the enclosure to separate an action region of the multi-axis robot and/or the displacement device from a secured people region. In the people region, material or tools may be prepared by a worker.

[0093] The processing system may include an auxiliary lifting device which is transported in an enclosure and displaced from the enclosure at the point of use. An auxiliary lifting device serves, for example, to reduce the weight to be handled by the multi-axis robot, since heavy objects can be handled by means of the auxiliary lifting device.

[0094] The processing system enables an automation of the working processes. This leads to a high and constant quality in the execution of the work and to an exact documentation of the work. Workers can be relieved and protected from environmental influences and dangers. Furthermore, work can be carried out easily and flexibly, in particular independently of a time of day.

[0095] The processing system according to the invention thus enables work on the railroad infrastructure to be carried out easily, flexibly, safely and reliably.
