Description

Technical Field

[0001] The present invention relates to a method for machining bogies of railway vehicles underground, wherein, in a first method step, a first wheelset or a first wheel of the railway vehicle is machined using a first tool, and in a second method step, a second wheelset or a second wheel of the railway vehicle is machined using the first tool, wherein, in order to change the machining position between the first method step and the second method step, relative movement is performed between the railway vehicle and the first tool. Background Technology

[0002] Manufacturing bogies (Fahrwerke, running gear) for rail vehicles may require machining processes that must be performed in sequence. Such machining processes typically result in time-consuming workflows. These processes may also require precise timing control as well as process and / or quality control.

[0003] For example, DE 10 2020 127 991 A1 is known from the prior art, which describes a method and apparatus for machining railway wheels. In this method, the flange of the railway wheel is quenched, wherein a laser spot is projected onto the flange by means of a heat source during the rotation of the railway wheel. The apparatus for implementing this method includes an underground lathe with clamping devices for maintaining the railway wheelset. The heat source for projecting the laser spot is associated with the clamping device.

[0004] Furthermore, DE 10 2017 122 023 A1 discloses an underground lathe for re-boring and re-finishing wheels and brake discs of rail vehicle wheelsets. This underground lathe can be used to machine wheelsets of different gauges. For this purpose, the components of the underground lathe bed can move relative to each other. Summary of the Invention

[0005] The objective of this invention is to provide a method that is an improvement over existing technologies, which enables the synchronization of the machining process on the bogie of a rail vehicle.

[0006] According to the present invention, this task is solved by the method according to claim 1, wherein, in the third method step, the third wheelset or the third wheel of the rail vehicle is machined using a second tool, and in the fourth method step, the first wheelset, the fourth wheelset, the first wheel, or the fourth wheel of the rail vehicle is machined using the second tool, wherein the second tool is moved to change the machining position between the third and fourth method steps. This measure improves the efficiency of the maintenance and / or repair process of the rail vehicle bogie. With the method according to the present invention, not only the wheels of the bogie can be machined, but also other wheelset components, such as brake discs, can be machined. By moving the second tool, the machining position on the rail vehicle can be flexibly reached. For example, when the first tool performs a first machining operation on the first wheelset, the second tool can perform a second machining operation on the third wheelset, and so on. Sequential machining processes can also be performed. For example, the first tool can first machine the first wheelset, wherein, after completing such machining of the first wheelset with the first tool, the second tool can be moved to the first wheelset and continue machining thereon. Thus, for example, machining can be performed on the first wheelset using a first tool (for which the first tool can be designed, for example, an underground lathe), followed by heat treatment using a second tool (for which the second tool can be designed, for example, a heat source), and so on. With the method according to the invention, the wheelset or wheel can be machined regardless of its position on the rail vehicle or the distance between them. Removing the wheelset or wheel from the rail vehicle can be avoided (e.g., to perform a third or fourth method step).

[0007] Other advantageous designs of the method according to the invention are described in the dependent claims.

[0008] For example, advantageously, the first and third method steps are executed within a first time interval beginning at a first start time, and the second and fourth method steps are executed within a second time interval beginning at a second start time. This allows the first and third method steps to be executed simultaneously or to overlap in time.

[0009] If the second and fourth method steps are executed after the first and third method steps in time, the timing of the method steps is staggered. This allows, for example, the first pair of wheels to be processed first using the first tool, and then using the second tool.

[0010] When performing the method according to the invention, different sequences can be considered, wherein, for example, it may be advantageous when the first and third method steps are performed temporally after the second and fourth method steps. By this measure, for example, the first wheel pair can be processed first using the second tool and then using the first tool.

[0011] An advantageous solution is obtained by moving the rail vehicle in the relative motion of changing the machining position between the first and second method steps. Thus, for the method according to the invention, for example, an infrastructure in which the rail vehicle is arranged, for example, on a maintenance track above a maintenance trench, and is positioned relative to a machining tool arranged in the maintenance trench by traveling on the maintenance track, in order to perform machining (e.g., machining of the first wheel equivalent, etc.).

[0012] If the rail vehicle translates along the first track and the second tool translates along the second track, wherein the first track and the second track are parallel to each other, then the second tool can move parallel to the direction of movement of the rail vehicle.

[0013] Furthermore, it is advantageous to perform machining in both the first and second method steps. Machining processes may include, for example, turning, milling, rolling, grinding, measurement, inspection, or mechanical cleaning.

[0014] If it is turned as a machining process, it can be used to turn, for example, rail vehicle wheelsets or wheels (e.g., for wheel boring or reboring).

[0015] If heat treatment is performed in the third and fourth steps of the method, a preferred solution is achieved. Examples of heat treatments include quenching, tempering, coating, welding, or heat cleaning.

[0016] For example, it is advantageous to perform quenching treatment as a heat treatment. This measure can, for example, improve the wear resistance of wheelsets or wheels of rail vehicles (e.g., after wheelset or wheel re-boring).

[0017] If, in the third method step, the third wheelset or third wheel is lifted and rotated using a lifting and rotating device, and in the fourth method step, the first wheelset, fourth wheelset, first wheel, or fourth wheel is lifted and rotated using the same lifting and rotating device, wherein, between the third and fourth method steps, the lifting and rotating device moves from a first position below the third wheelset or third wheel to a second position below the first wheelset, fourth wheelset, first wheel, or fourth wheel, then the entire circumference of the wheelset or wheel can be processed using a second tool. By moving this lifting and rotating device, the processing position on the rail vehicle can be flexibly reached. Furthermore, flexible height control of the rail vehicle wheelset or wheel is achieved.

[0018] If process parameters are recorded at least during the third and fourth method steps, precise process control and / or automated quality control can be achieved. Process parameters can include, for example, the power of the heat source, rotational speed, the duration of the processing, and / or heat absorption. These parameters, such as heat source power, can also be recorded in relation to time, rotational speed, or rotational angle. Recorded process parameters can also be stored (e.g., for evaluation).

[0019] A promising application area for the method according to the invention can be explored through an apparatus for underground machining of rail vehicle bogies, the apparatus being configured to perform the method according to the invention, wherein the apparatus includes a first tool and a second tool, and a lifting and rotating device, wherein the first tool is configured to machine a first wheelset or a first wheel of the rail vehicle in a first method step, and a second wheelset or a second wheel of the rail vehicle in a second method step, wherein the second tool is configured to machine a third wheelset or a third wheel of the rail vehicle in a third method step, and to machine a first wheel in a fourth method step. A wheelset, a fourth wheelset of a rail vehicle, a first wheel, or a fourth wheel of a rail vehicle, wherein at least a second tool is configured to be movable to change processing positions, wherein the second tool is configured to move between a third method step and a fourth method step, and wherein a lifting and rotating device is configured to lift and rotate the third wheelset or third wheel in the third method step, lift and rotate the first wheelset, the fourth wheelset, the first wheel, or the fourth wheel in the fourth method step, and move from a first position below the third wheelset or third wheel to a second position below the first wheelset, the fourth wheelset, the first wheel, or the fourth wheel between the third and fourth method steps. This measure enables efficient maintenance and / or repair processes on rail vehicle bogies, wherein the maintenance and / or repair processes can be synchronized and time-staggered, for example.

[0020] If the device includes a track configured to move rail vehicles thereon, wherein at least a first tool and a lifting and rotating device are at least partially arranged below the track, then the device according to the invention can be used in maintenance and / or repair equipment for rail vehicles with track infrastructure.

Figure 1 Heat treatment is performed in one step of the exemplary embodiment of the method for underground machining of railway vehicle bogies according to the present invention. Detailed Implementation

[0023] Figure 1 A flowchart illustrating an exemplary embodiment of the method for underground machining of rail vehicle bogies according to the present invention is shown. Rail vehicle 1, such as..., is machined using this method. Figure 2 and Figure 3 As shown in the example.

[0024] In step 2 of the first method, the first wheel 6 of the first wheelset 10 of the first bogie 14 of the rail vehicle 1 is machined using a first tool 17, thereby performing a re-boring. This first tool is designed as a turning tool for an underground lathe and... Figure 2 and Figure 3 As exemplarily shown, the first rolling surface and the first rim of the first wheel 6 are machined.

[0025] In step 3 of the second method, the second wheel 7 of the second wheelset 11 of the second bogie 15 of the rail vehicle 1 is machined with the aid of the first tool 17, and thus re-bored.

[0026] Therefore, turning is performed in the first method step 2 and the second method step 3. These are machining operations, in which the first bogie 14 and the second bogie 15 are machined.

[0027] To change the machining position between step 2 of the first method and step 3 of the second method, relative movement is performed between the rail vehicle 1 and the first tool 17. During this relative movement, the rail vehicle 1... Figure 2 and Figure 3 The track vehicle 1 moves along the track 19 above the maintenance trench 20, as exemplarily shown. The track vehicle 1 moves along the positive axis of the x-axis 21, as... Figure 2 and Figure 3 As shown in the example.

[0028] In step 2 of the first method, the first tool 17 is positioned below the first wheel 6, and in step 3 of the second method, it is positioned below the second wheel 7.

[0029] In step 4 of the third method, the third wheel 8 of the third wheelset 12 of the first bogie 14 is machined using a second tool 18. This second tool is designed as a heat source to generate a laser spot. The laser spot is used to scan the second rolling surface and the second rim of the third wheel 8, such as... Figure 2 and Figure 3 As exemplarily shown, the third wheel 8 has been re-bored using the first tool 17 prior to step 4 of the third method.

[0030] In step 5 of the fourth method, as follows Figure 4 As also exemplarily shown, the first wheel 6 is processed with the aid of a second tool 18, wherein the first rolling surface and the first rim of the first wheel 6 are scanned by means of a laser spot.

[0031] The surfaces of the third wheel 8 and the first wheel 6 are hardened by scanning with a laser spot. Therefore, the hardening process is carried out in steps 4 of the third method and step 5 of the fourth method; these are heat treatments.

[0032] To change the machining position between step 4 of the third method and step 5 of the fourth method, the second tool 18 is moved. The second tool 18 is arranged at the same height as the track 19 and guided on the first guide rail by the first traveling wheel. In step 4 of the third method, the second tool 18 is arranged near the third wheel 8, and in step 5 of the fourth method, it is arranged near the first wheel 6. The second tool 18 can move along the track vehicle 1 and the track 19.

[0033] To change the processing position between step 2 of the first method and step 3 of the second method, the rail vehicle 1 translates along a first trajectory preset by the rail 19. The second tool 18 translates along a second trajectory preset by the first guide rail. The first trajectory and the second trajectory are parallel to each other.

[0034] In step 4 of the third method, the first bogie 14, comprising the first wheelset 10, the first wheel 6, the third wheelset 12, and the third wheel 8, is lifted by means of the lifting and rotating device 22. Figure 2 and Figure 3 As exemplarily shown, the third wheel 8 is rotated by means of the rollers of the lifting and rotating device 22 that contact the third wheel 8, so as to perform processing by means of the second tool 18.

[0035] In step 5 of the fourth method, the first bogie 14 having the first wheelset 10, the first wheel 6, the third wheelset 12 and the third wheel 8 are lifted again by means of the lifting and rotating device 22, but now the first wheel 6 is rotated by means of the rollers of the lifting and rotating device 22 that are now in contact with the first wheel 6, so that the first wheel 6 can be processed by means of the second tool 18.

[0036] The lifting and rotating device 22 is designed as a lifting platform, with rollers arranged on its upper side for rotating the wheels of the rail vehicle 1. On its lower side, the lifting and rotating device 22 has second traveling wheels, through which it is movable on a second guide rail within the maintenance trench 20. The lifting and rotating device 22 is arranged on the second guide rail. Thus, between the third method step 4 and the fourth method step 5, the lifting and rotating device 22 moves from a first position below the third wheelset 12 to a second position below the first wheelset 10.

[0037] Steps 2 and 4 of the first method are executed within a first time interval beginning at a first start time. Steps 3 and 5 of the second method are executed within a second time interval beginning at a second start time. Steps 3 and 5 of the second method are executed after steps 2 and 4 of the first method. On the one hand, steps 2 and 4 of the first method, and on the other hand, steps 3 and 5 of the second method, are executed out of time, wherein steps 2 and 4 of the first method are executed simultaneously, and steps 3 and 5 of the second method are executed simultaneously. According to the present invention, it is conceivable that, for example, steps 2 of the first method overlaps with steps 4 of the third method in time, and steps 3 of the second method overlap with steps 5 of the fourth method in time, for example, when the duration of steps 2 of the first method is longer than that of steps 4 of the third method, and the duration of steps 3 of the second method is longer than that of steps 5 of the fourth method.

[0038] During steps 2, 3, 4, and 5 of the first method, the wheel rotation speed and the duration of the processing are recorded as process parameters. During steps 4 and 5, the heat source power and the heat absorption of the third wheel 8 and the first wheel 6 are additionally recorded, in relation to time and wheel rotation speed, as process parameters. These process parameters are recorded using sensors. The sensor measurements are transmitted via signal lines to a computing unit in the maintenance equipment control room for storage and evaluation. The sensor measurements are also used to control the method from the control room.

[0039] According to the present invention, it is also conceivable that in the fourth method step 5, a different wheelset or other wheel than the first wheelset 10 or the first wheel 6 may be processed. For example, the fourth wheelset 13 or the fourth wheel 9 of the third bogie 16 of the rail vehicle 1 may be processed.

[0040] According to the present invention, it is also conceivable that, depending on the needs and the tools used, it can be combined with... Figure 1 The different processing sequences are executed in this method. For example, step 2 of the first method and step 4 of the third method may also be executed after step 3 of the second method and step 5 of the fourth method, etc.
