Disclosure of Invention

The object of the invention is to achieve a simply constructed processing machine which enables a user-friendly, flexible and safe processing of a rail.

This object is achieved by a processing machine having the features of claim 1. Since the energy supply unit and the processing unit are configured to be separated from each other, the energy supply unit and the processing unit can be operated in a spatially separated manner. The processing machine comprises in particular an energy transmission connection which is connected to an energy supply unit and to a processing unit for the transmission of energy. The energy supply unit and the processing unit form separate functional units which, in operation of the processing machine, are connected to one another only by means of the energy transmission connection, so that the processing unit is supplied with the energy required for operation. The energy transmission connection comprises at least one supply line for supplying energy and optionally at least one signal line for transmitting energy for the signal. At least one signal line is preferably used for controlling the processing unit. Due to the separate arrangement, the processing unit is relatively light and easy to handle. The energy supply unit and the processing unit are in particular configured to be mechanically separated from each other. Only the machining unit must be manually started and repositioned to finish the track. The energy supply unit is held in a fixed position during the machining of the rail. Thus, the energy supply unit is not repositioned during the machining of the rail. Thus, the energy supply unit and the processing unit are configured to be separated from each other in the following manner: so that the energy supply unit and the processing unit can be repositioned in a mutually independent manner. In particular, the machining unit can be repositioned without the energy supply unit being repositioned at the same time, and vice versa. The machining radius is limited only by the energy transmission connection and its length. The length L of the energy transmission link is preferably: l is more than or equal to 2m and less than or equal to 30m, particularly 3m and less than or equal to 20m, particularly 4m and less than or equal to 10 m. During machining, the energy supply unit can remain in a fixed position and must only be repositioned when further machining of the track is performed outside the initial machining radius. The machining of the rail can be carried out at a desired spacing from the energy supply unit, so that the operator is not hindered by emissions (e.g. noise and/or exhaust emissions) of the energy supply unit. The processing machine thus enables a user-friendly, flexible and safe processing of the rail.

The energy transmission connection is in particular configured electrically, hydraulically and/or mechanically. The energy transmission connection is configured, for example, as an electrical supply line, a hydraulic supply line and/or a flexible mechanical drive shaft. Preferably, the processing unit is operable by means of electrical, hydraulic and/or mechanical energy.

The energy supply unit comprises in particular at least one electrical connector. The at least one electrical connector is configured as a DC voltage socket, an AC voltage socket, a USB socket, and/or a machine specific connector. The energy supply unit preferably comprises a converter, in particular a rectifier and/or an inverter, to provide a DC voltage and/or an AC voltage. The voltage level is preferably adjustable and/or selectable. The energy supply unit and/or the processing unit preferably comprise at least one connector for connecting an electrical supply line for supplying energy for operating the processing unit.

The processing unit is configured, for example, as a track grinding unit, an assembly unit for assembling a track and/or a compactor unit for compacting a ballast bed. The energy supply unit is preferably connectable in an energy-transmitting manner to the various processing units, so that depending on the desired processing, different processing units can be operated using a single energy supply unit.

The processing machine according to claim 2 ensures a user-friendly and flexible processing. Due to the at least one guide roller, the energy supply unit can be repositioned, in particular displaced manually, on the rails of the track in a simple manner. The energy supply unit comprises in particular at least two guide rollers, in particular at least three guide rollers, in particular at least four guide rollers. At least two guide rollers are rotatably mounted on the support frame, for example in the following manner: so that the energy supply unit can be relocated on one rail or on both rails of the track. At least one guide roller is used for manually displacing or repositioning and/or motorized repositioning, respectively, the energy supply unit.

At least one guide roller is preferably arranged on the support frame in the following manner: the energy supply unit can be repositioned, in particular manually displaced, on only one of the rails, so that on the one hand the energy supply unit blocks only one of the rails and on the other hand only one of the rails must be free of obstacles in order to displace the energy supply unit. Thus, the energy supply unit can be relocated from one track position to another track position in a user-friendly and flexible manner.

At least two guide rollers are preferably arranged on the support frame in the following manner: so that the energy supply unit can be repositioned, in particular manually displaced, on both rails. The energy supply unit can thus be easily relocated, in particular manually and/or mechanically displaced, on the rails and alongside the rails, for example on a road or paved road (befestigen Weg). It is possible to stop the energy supply unit in a simple and reliable manner and to fix the energy supply unit in the desired position without automatic repositioning.

The processing machine according to claim 3 ensures a user-friendly and flexible processing. Due to the arrangement of the guide rollers in the longitudinal direction of the rails, the energy supply unit can be repositioned, in particular manually displaced, in a simple manner only along one of the rails. The arrangement of the guide rollers is used in particular for manually displacing the energy supply unit on one rail of the track. Furthermore, the energy supply unit can be tilted about the rail, so that the energy supply unit can be tilted and supported on the sleeper and/or the ballast bed, respectively, when it is displaced manually on the rail.

The processing machine according to claim 4 enables user-friendly and safe processing. Due to the at least one supporting element, it is thus possible to support the energy supply unit on the sleeper and/or the ballast bed, respectively, so that the energy supply unit is fixed in a simple manner upon manual displacement without automatic repositioning, for example in the case of steep rails. The at least one support element is arranged laterally with respect to the at least one guide roller, so that the energy supply unit can be supported and fixed by simple tilting on or around the rail, respectively. The energy supply unit preferably has a plurality of support elements which are arranged on both sides of the at least one guide roller and/or in the longitudinal direction of the rail or in the displacement direction of the energy supply unit. Thus, flexibility and safety are improved. The at least one support element is for example configured to support a carrier.

The processing machine according to claim 5 ensures a user-friendly, flexible and safe processing. Since the at least one support element can be repositioned relative to the at least one guide roller, on the one hand the spacing between the at least one support element and the sleeper is adjustable for manually displacing the energy supply unit, and on the other hand the size of the inclination is adjustable for supporting the energy supply unit. The repositioning may preferably be done in such a way that: in the displaced state of the energy supply unit, the at least one support element does not project beyond the at least one guide roller in the direction of the ground surface, so that the energy supply unit can be displaced manually on the at least one guide roller which is also on a firm ground surface.

The processing machine according to claim 6 ensures a user-friendly and safe processing. The at least one handle enables a user-friendly manual displacement and/or manual tilting of the energy supply unit. The at least one handle is preferably at least partially repositionable relative to the support frame of the energy supply unit so that the energy supply unit has a compact configuration for transport to and removal from the site or for storage. The at least one handle is particularly configured to be pivotable and/or telescopic.

The processing machine according to claim 7 ensures a user-friendly and flexible processing. At least one mounting frame makes it possible to manually displace the energy supply unit and the processing unit jointly. After machining the rail at the first rail position, the operator can arrange the machining unit in the at least one mounting frame such that the machining unit is temporarily held in the at least one mounting frame. Subsequently, the operator can manually displace the energy supply unit together with the processing unit held thereon to the second rail position for further processing at said second rail position. To this end, the operator can remove the machining unit again from the at least one mounting frame and carry out further machining at the second rail position.

The processing machine according to claim 8 ensures flexible processing. The accumulator is particularly configured as a rechargeable battery and/or a capacitor. It is possible to provide a large storage capacity for the rechargeable battery, since on the one hand the weight of the rechargeable battery does not hinder the handling of the processing unit and, on the other hand, the energy supply unit remains user-friendly in terms of handling. The capacitor is particularly provided by an electrical power generator comprising an internal combustion engine, a generator coupled to the internal combustion engine, and a charging circuit. The capacitor ensures energy-optimized and emission-optimized handling of the internal combustion engine, thereby increasing user friendliness. The energy supply unit and/or the processing unit preferably have a lighting device, which is supplied in particular by means of an electrical energy accumulator.

The processing machine according to claim 9 ensures a simple construction. Since the energy supply unit and the processing unit have separate support frames, a mechanical separation of the energy supply unit and the processing unit is ensured in a simple manner. In this way, the energy supply unit and the processing unit are configured with separate functional units which can be displaced and operated in an independent manner from one another.

The processing machine according to claim 10 ensures a user-friendly and flexible processing. Since the energy supply unit and the processing unit each have a dedicated handle, the energy supply unit and the processing unit can be displaced and operated independently of each other and in a simple and user-friendly manner.

The processing machine according to claim 11 ensures a user-friendly and flexible processing. Since the processing unit has dedicated guide rollers, the processing unit can be displaced manually along one of the rails of the track independently of the energy supply unit. The machining can thus take place, for example, on the first rail and/or on the second rail, on which the energy supply unit is relocated. Since the weight of the machining unit is relatively light, it is easy to change the machining unit from one rail to another. The guide rollers are arranged in particular along the longitudinal direction of the rails, so that the machining unit can be displaced manually in a simple manner only along one of the rails. Due to the arrangement of the guide rollers, the machining unit can in particular also be tilted around the rail. Therefore, the application field of the processing unit is expanded.

The processing machine according to claim 12 ensures a user-friendly and flexible processing by grinding. The rail grinding unit comprises in particular a support frame on which a plurality of guide rollers are rotatably mounted and on which a grinding device is arranged. The grinding apparatus preferably comprises a grinding tool which can be driven rotationally by an electric or hydraulic drive motor. The height of the grinding tool relative to the support frame is adjustable, for example manually or by means of an electric motor. A separate handle for the operator is in particular arranged on the support frame.

The processing machine according to claim 13 ensures a user-friendly and flexible processing. Due to the at least one wheel, the energy supply unit can be transported to the rail in a simple and user-friendly manner. The at least one wheel is particularly suitable for repositioning the energy supply unit on a firm ground, such as a road or a paved road. The energy supply unit preferably has at least two wheels mounted on the support frame spaced apart along a common axis of rotation. At least two wheels are preferably arranged on the side of the support frame assigned to the handle. The energy supply unit can thus be pivoted about the axis of rotation of the wheel and can thus be repositioned on the wheel by means of the handle. At least one wheel has in particular in each case a rim and a tire arranged on the rim.

The processing machine according to claim 14 ensures a user-friendly and flexible processing. The energy supply unit is repositioned in a motorized manner by means of at least one auxiliary drive. In particular in a motorized manner to facilitate manual repositioning of the energy supply unit. The at least one auxiliary drive is preferably configured as an electric drive motor. The respective electric drive motor is preferably operated by means of an accumulator. At least one auxiliary drive is used for rotationally driving the at least one guide roller and/or the at least one wheel. At least one guide roller and/or at least one wheel is mounted so as to be rotatable on a support frame of the energy supply unit. For example, respective auxiliary drives are provided to drive the at least one guide roller and to drive the at least one wheel. Furthermore, for example, a common auxiliary drive is provided for driving or selectively driving the at least one guide roller and the at least one wheel, respectively. The auxiliary drive can be selectively coupled to the at least one guide roller or the at least one wheel, in particular by means of a gearbox.

The processing machine according to claim 15 ensures a user-friendly and flexible processing. The transport surface is used, for example, for transporting the processing unit and/or the tool. The energy supply unit preferably has a conveying container which comprises a conveying surface with a side wall surrounding the conveying surface. The transport container can in particular be closed by means of a lid.

Furthermore, the object of the invention is to achieve a method which enables user-friendly, flexible and safe machining of steel rails.

This object is achieved by a method having the features of claim 16. The advantages of the method according to the invention correspond to the advantages of the processing machine according to the invention already described.

Detailed Description

A first exemplary embodiment of the present invention is described below with reference to fig. 1 to 6. The processing machine 1 shown in fig. 1 is used for processing a track 2. The track 2 comprises a first rail 3 and a second rail 4, the first rail 3 and the second rail 4 being fastened to sleepers 5, the sleepers 5 being arranged in the ballast bed S or the track bed, respectively.

The processing machine 1 comprises an energy supply unit 6 for providing electrical power and an electrically operable processing unit 7, said energy supply unit 6 and said processing unit 7 being configured to be mechanically separated from each other and to form separate functional units. For being supplied with electrical power, the processing unit 7 is connected with the energy supply unit 6 by means of an energy transmission connection in the form of a supply line 8. To this end, the supply line 8 is releasably connected to the energy supply unit 6 by means of a first connector terminal 9 and to the processing unit 7 by means of a second connector terminal 10. The length L of the energy transmission link is preferably: 2 m.ltoreq.L.ltoreq.30 m, in particular 3 m.ltoreq.L.ltoreq.20 m and in particular 4 m.ltoreq.L.ltoreq.10 m.

The energy supply unit 6 comprises a support frame 11, on which support frame 11 two guide rollers 12, 13 are mounted so as to be rotatable about associated axes of rotation 14, 15. The guide rollers 12, 13 are arranged on the support frame 11 in such a way that: such that the guide rollers 12, 13 are aligned with one another in the rail longitudinal direction 16 or in the displacement direction, respectively, and the axes of rotation 14, 15 are spaced apart in the rail longitudinal direction 16, so that the energy supply unit 6 can be displaced selectively on one of the rails 3 or 4 manually.

A handle 17 for manual displacement is fastened to the support frame 11. For example, the handle 17 is fastened to be fixed on the support frame 11 or can be folded on the support frame 11. In addition, the energy supply unit 6 has a handle 18 and a fastening eye 19 for the delivery, said handle 18 and said fastening eye 19 being fastened to the support frame 11. For example, the handle 18 is laterally arranged to be fixed on the support frame 11 or arranged to be foldable on the support frame 11.

For being supported and fixed, the energy supply unit 6 has two first support elements 20 and two second support elements 21. The first support element 20 is arranged on a first side of the guide rollers 12, 13, while the second support element 21 is arranged on an opposite second side of the guide rollers 12, 13. The first support elements 20 are spaced apart from one another in the rail longitudinal direction 16. The second supporting elements 21 are correspondingly spaced apart from one another in the rail longitudinal direction 16. The support elements 20, 21 are configured to support a carrier.

The support elements 20, 21 are fastened to the support frame 11 so as to be repositionable perpendicular to the plane E defined by the rotation axes 14, 15. The repositionable fastening is for example performed by a slot-screw connection (not shown in more detail). Due to the repositionable fastening of the support elements 20, 21, the support elements 20, 21 can be height-adjustable relative to the guide rollers 12, 13 or relative to the plane E defined by the axes of rotation 14, 15, respectively. In other words, the spacing a between the plane E defined by the rotation axes 14, 15 and the respective support face F of the support elements 20, 21 is adjustable.

The energy supply unit 6 further comprises a mounting frame 22 for temporarily holding the processing unit 7. The mounting frame 22 comprises two first holding elements 23 and a second holding element 24, said holding elements 23 and 24 being arranged on the support frame 11. The mounting frame 22 is arranged substantially centrally with respect to the guide rollers 12, 13. The mounting 22 is preferably arranged on the opposite side of the support frame 11 to the handle 17. The first holding elements 23 are arranged laterally side by side, while the second holding elements are arranged centrally with respect to the first holding elements 23 and below the first holding elements 23, so that a three-point mounting is configured.

For providing electrical power, the energy supply unit 6 comprises an electrical energy generator 25, the electrical energy generator 25 comprising an internal combustion engine 26, a generator 27 and a charging device 28. The generator 27 is mechanically coupled to the internal combustion engine 26 on the one hand and is electrically connected to a charging device 28 on the other hand, the charging device 28 providing a charging voltage or a DC voltage, respectively, on the output side. The accumulator 29 of the energy supply unit 6 is charged by means of a charging voltage. The energy accumulator 29 is in particular a capacitor or a capacitor circuit and/or a rechargeable battery. For the design of the circuit, reference is made to DE 202016005841U 1.

The machining unit 7 is configured as a rail grinding unit. The processing unit 7 includes a support frame 30, and guide rollers 31, 32 are rotatably mounted on the support frame 30. The guide rollers 31, 32 are arranged on the support frame 30 in such a way that: so that the machining unit 7 can be selectively displaced manually on the first rail 3 or the second rail 4. The first support frame 11 of the energy supply unit 6 and the second support frame 30 of the machining unit 7 are configured to be mechanically separated from each other such that the machining unit 7 can be repositioned independently of the energy supply unit 6. For this purpose, a handle 33 is arranged on the support frame 30.

The grinding device 34 is fastened to the support frame 30 such that the grinding device 34 is substantially centered between the guide rollers 31, 32. The grinding device 34 comprises a grinding tool 35, which grinding tool 35 can be driven in rotation about a rotation axis 37 by means of an electric drive motor 36. The grinding tool 35 is manually adjustable in height in the direction of the axis of rotation 37. The construction of the grinding apparatus 34 is known and conventional.

The processing machine 1 has a lighting device with a plurality of light elements 38, 39, the light elements 38, 39 being arranged on the one hand on the energy supply unit 6 and on the other hand on the processing unit 7.

The functional modes of the processing machine 1 are as follows:

in fig. 1, the operating state of the processing machine 1 in the first path position can be seen. The processing unit 7 in the operating state is connected to the energy supply unit 6 by means of a supply line 8. The energy supply unit 6 is arranged on one of the rails 3 or 4, for example on the rail 3, as shown in fig. 1. The energy supply unit 6 is in an inclined position in the operating state, so that the support element 20 is supported, for example, in one of the sleepers 5 and/or the ballast bed 8. This can be seen in fig. 6. Thus, the energy supply unit 6 is fixed to prevent any undesired repositioning, for example in case of steep rails 2, so that no safety brake is required. When required, the support element 20 can be repositioned relative to the support frame 11 so that the spacing a between the plane E and the support face F is adjustable. The tilt angle can thus be set.

The rail 2 is machined by means of a machining unit 7, so that the machining unit 7 is spatially separated from the energy supply unit 6. The machining radius is limited only by the length of the supply line 8. The rail 3 or the rail 4 can be selectively dressed during grinding. Due to the relatively low weight of the machining unit 7, the machining unit 7 can be repositioned manually from one rail to the other rail 3 or 4 in a simple manner. The grinding is performed by manually displacing the machining unit 7 onto the respective rail 3 or 4. For example, the grinding of the rail 4 can be seen in fig. 1. The light elements 38 and/or 39 can be switched on during the process when required.

Once the machining of the track 2 along the machining radius is completed, the machining machine 1 has to be manually displaced. For this purpose, the processing machine 1 is moved from the operating state shown in fig. 1 into the displaced state visible in fig. 3 to 5. In the displaced state, the supply line 8 is released from the energy supply unit 6 and the processing machine 7 and is arranged in a fixed state on the energy supply unit 6. The processing unit 7 is arranged in the mounting frame 22 such that said processing unit 7 is temporarily held on the energy supply unit 6. The processing machine 1 or the energy supply unit 6 is then correspondingly tilted into a horizontal position, so that the support surface F no longer bears on the sleepers 5 and/or the ballast bed S. The horizontal position is visible in fig. 4 and 5. If necessary, the spacing a can be reduced by repositioning the support element 20 or 21, respectively, so that the processing machine 1 or the energy supply unit 6, respectively, in the displaced state has an increased clearance with respect to the sleepers 5 or the ballast bed S. This is visible for the support element 20 in fig. 5.

The processing machine 1 can now be displaced manually on the rail 3 in a simple manner by means of the handle 17 until the desired second track position is reached. In the second track position, the processing machine 1 is switched back from the shift state to the operating state in the reverse order.

The transport of the processing machine 1 to the rail 2 and away from the rail 2 by means of the handle 18 makes it possible to reposition the processing machine 1 or only the energy supply unit 6 by a plurality of operators. Alternatively, the processing machine 1 can be repositioned by means of a lifting device engaged on the fastening eye 19. For transport to and from the site, the processing machine 1 is preferably in a displaced state visible in fig. 3. Alternatively, the energy supply unit 6 and the processing unit 7 can be transported to and removed from the site separately from each other.

A second exemplary embodiment of the invention is described below with the aid of fig. 7. In contrast to the previous exemplary embodiments, the support elements 20, 21 are pivotable about the associated pivot axes 20 'and 21', so that the support face F can be repositioned about the plane E. In other words, the support elements 20, 21 can pivot in such a way that the spacing a is zero or less, respectively. In this displaced state, the guide rollers 12, 13 are therefore no longer located above the support surface F, so that the energy supply unit 6 or the processing machine 1, respectively, can be manually repositioned on a firm floor, for example on a floor beside the rail 2. Thus, flexibility is improved. Further, the handle 17 is configured to be retractable and foldable. The processing machine 1 can thus be converted into a compact state when being transported to and from the site. With regard to other configurations and other functional modes of the processing machine 1, reference is made to the preceding exemplary embodiments.

A third exemplary embodiment of the present invention is described below with the aid of fig. 8 to 10. Contrary to the previous exemplary embodiment, the energy supply unit 6 has, in addition to the guide rollers 12, 13, two wheels 40, 41, the two wheels 40, 41 being rotatably mounted on the support frame 11. The wheels 40, 41 are rotatable about a rotation axis 42. The wheels 40, 41 are arranged on the side of the support frame 11 facing the handle 17, so that the energy supply unit 6 can be tilted about the axis of rotation 42 by means of the handle 17 and can be freely repositioned on the wheels 40, 41. In order to be able to be stopped, the energy supply unit 6 has a foot 43 on the side of the support frame 11 opposite the wheels 40, 41. The wheels 40, 41 each comprise a rim 44 and a tire 45 arranged on the rim 44.

The electric storage 29 is arranged on the support frame 11. In particular, the energy supply unit 6 does not have any internal combustion engine or any generator. The accumulator 29 provides an electrical connector V for connecting the electrical supply line 8. The accumulator 29 also supplies a DC voltage socket G and, via the converter 46, an AC voltage socket W. For this purpose, the converter 46 is configured as an inverter. A control unit 47 arranged on the support frame 11 monitors the accumulator 29 and controls the converter 46 to supply the voltage. The control unit 47 includes a USB socket B.

To support the manual repositioning, the energy supply unit 6 has a first auxiliary drive 48 for driving the guide roller 12 and a second auxiliary drive 49 for driving the wheel 41. The auxiliary drives 48, 49 are configured as electric drive motors.

The energy supply unit 6 comprises a transport container 50. The conveying container 50 is arranged on the upper side of the support frame 11 facing away from the guide rollers 12, 13 or the wheels 40, 41, respectively. The transport container 50 includes a transport surface 51 surrounded by a sidewall 52. With regard to other configurations and other functional modes of the processing machine 1, reference is made to the preceding exemplary embodiments.

A fourth exemplary embodiment of the invention is described below with the aid of fig. 11 to 13. Contrary to the previous exemplary embodiment, four guide rollers 12, 13, 12 'and 13' are mounted to be able to rotate on the support frame 11. The guide rollers 12, 13 are arranged in the described manner in alignment with one another in the rail longitudinal direction 16, wherein the associated axes of rotation 14, 15 are arranged spaced apart from one another in the rail longitudinal direction 16. The guide rollers 12 ', 13' are also correspondingly arranged aligned with one another along the rail longitudinal direction 16, with the associated axes of rotation 14 ', 15' arranged spaced apart from one another in the rail longitudinal direction 16. The axes of rotation 14 and 14 'and the axes of rotation 15 and 15' are aligned with each other. The spacing of the guide rollers 12, 13 from the guide rollers 12 ', 13' corresponds to the spacing of the rails 3, 4, so that the energy supply unit 6 can be repositioned on the first rail 3 by means of the guide rollers 12, 13 and the energy supply unit 6 can be repositioned on the second rail 4 by means of the guide rollers 12 ', 13'. The guide roller 12 can be driven, for example, by means of an auxiliary drive 48, so that a manual displacement of the energy supply unit 6 is supported. The auxiliary drive 48 drives the guide roller 12, for example, by means of a transmission mechanism which is not shown in greater detail. In order to fix the energy supply unit 6 against automatic repositioning, the energy supply unit 6 has a brake 53 for blocking at least one of the guide rollers 12, 13, 12 ', 13'. With regard to other configurations and other functional modes of the processing machine 1, reference is made to the preceding exemplary embodiments.

The processing unit 7 can be configured as a grinding unit, an assembly unit or a compactor unit. The energy supply unit 6 can be selectively operated together with different processing units 7.
