Description

[0002] The bogie components of rail vehicles are equipped with fast transmission cables, grounding cables, etc. The cables include a static section arranged on the main frame and a dynamic section from the axle end to the frame. The state of these cables will be affected by the change in the relative position of the frame and the wheelset. During the assembly of rail vehicles, the length of the cables needs to be strictly tested and verified to ensure the safety and reliability of vehicle driving.

[0003] At present, the rail vehicle cables are simulated and wired using CATIA software. During the execution process, the software simulates the cable routing layout, determines the cable length through simulation, and then produces the corresponding length of cable for installation.

[0024] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Combine the following Figures 1 to 5 A simulation test device for cables according to the present invention is described.

[0026] like Figures 1 to 5 As shown, the simulation test device for cables provided in an embodiment of the present invention includes a transverse bracket 1, a vertical bracket 2, a rotating bracket 3, a first wire clamp 4 and a second wire clamp 5.

[0027] Specifically, the axis of the transverse support 1 is arranged along a reference direction. Figure 1 and Figure 2 The direction indicated by the m.

[0028] The simulation test device for cables provided in this embodiment may be provided with a base 31 for support, and the transverse bracket 1 may be fixedly arranged on the base 31 to improve the stability of the simulation test device for cables.

[0029] The axis of the vertical bracket 2 is perpendicular to the axis of the horizontal bracket 1, and the vertical bracket 2 can be reciprocatingly slidably arranged on the horizontal bracket 1 along the reference direction. The rotating bracket 3 can be rotatably arranged on one end of the horizontal bracket 1, and the rotating bracket 3 is arranged along the reference direction relative to the rotation axis of the horizontal bracket 1.

[0030] By sliding the vertical bracket 2, the distance between the vertical bracket 2 and the rotating bracket 3 can be adjusted. By rotating the rotating bracket 3, the relative angle between the rotating bracket 3 and the vertical bracket 2 in the three-dimensional space can be adjusted. Figure 1 and Figure 2 .

[0031] The first wire clamp 4 is arranged on the vertical support 2, and the second wire clamp 5 is arranged on the transverse support 1. The first wire clamp 4 can slide back and forth along the axis of the vertical support 2, and the second wire clamp 5 can slide back and forth along the axis of the rotating support 3. Through the sliding of the first wire clamp 4 and the second wire clamp 5, the positions of the first wire clamp 4 and the second wire clamp 5 relative to the transverse support 1 can be adjusted.

[0032] By combining the sliding of the vertical bracket 2, the rotation of the rotating bracket 3, the sliding of the first wire clamp 4 and the sliding of the second wire clamp 5, the first wire clamp 4 and the second wire clamp 5 can be adjusted to any relative position in the three-dimensional space.

[0033] The first wire clamp 4 can rotate relative to the vertical bracket 2, and the rotation axis of the first wire clamp 4 relative to the vertical bracket 2 is perpendicular to the axis of the transverse bracket 1 and the axis of the vertical bracket 2. The second wire clamp 5 can rotate relative to the rotating bracket 3, and the rotation axis of the second wire clamp 5 relative to the rotating bracket 3 is perpendicular to the axis of the transverse bracket 1 and the axis of the rotating bracket 3.

[0034] By rotating the first wire clamp 4 and the second wire clamp 5, the installation direction of the first wire clamp 4 and the second wire clamp 5 to the cable end can be adjusted so that the installation direction of the cable end on the simulation test device for cables provided in the embodiment of the present invention is consistent with the actual installation direction of the cable end on the rail vehicle.

[0035] With such a configuration, the simulation test device for cables provided by the embodiment of the present invention can be used to simulate the positions and directions of the two ends of the cables to be assembled, and to actually install the cables in the simulated positions and directions to be assembled. The cables installed on the simulation test device are the cables actually used in the assembly of rail vehicles. The simulation results of the cables are based on the actual hardness and bending radius of the cables, which improves the accuracy of the simulation results, thereby improving the design accuracy of the cables, and solves the problem of inaccurate simulation results of cable length in the related art that only software is used to simulate wiring, avoids the problem of material waste caused by inaccurate simulation results, avoids the impact on project progress, reduces costs, and improves production efficiency.

[0036] When simulating the installation of the cable using the simulation test device for the cable provided by the embodiment of the present invention, the adjustment of the simulation test device for the cable is performed according to the position and direction of the cable to be assembled. If there is relative movement between the two components to which the cable is actually connected, the relative movement of the two components will drive the cable to move. During the simulation, the two extreme relative positions of the two components can be simulated successively. For example, if the two components rotate relative to each other, the relative position angle of the first wire clamp 4 and the second wire clamp 5 is adjusted according to the relative position of the two components at the minimum relative angle. After the cable is installed on the first wire clamp 4 and the second wire clamp 5, the state of the cable is observed to ensure that the cable is naturally bent and not tight. Then, according to the relative position of the two components at the maximum relative angle, the relative position angle of the first wire clamp 4 and the second wire clamp 5 is adjusted, and the state of the cable is observed to ensure that the cable is naturally bent and not tight. In the two states of the simulation test device for the cable, the cable is in a state of natural bending and not tight, and the length of the cable meets the requirements, so that the length of the cable can be determined.

[0037] When the cable is installed in the simulation test device for cables provided in this embodiment, the length of the cable has been determined by the simulated wiring of the three-dimensional software. If the cable is not in a naturally complete and loose state when the cable is installed in the simulation test device for cables provided in this embodiment, the length of the cable needs to be adjusted. The length of the cable can be determined only when the cable is adjusted to a naturally bent and loose state.

[0038] The simulation test device for cables provided in this embodiment has six degrees of freedom, and can adjust the first wire clamp 4 and the second wire clamp 5 to any relative position angle in a three-dimensional space, which can realize not only static simulation tests on cables, but also dynamic simulation tests on cables. Moreover, it can realize simulation tests on cables of different materials and lengths, and can be applied to simulation tests on cables on rail vehicles of different models, and has strong adaptability.

[0039] In the embodiment of the present invention, the simulation test device for cables further includes a first locking mechanism, a second locking mechanism, a third locking mechanism and a fourth locking mechanism.

[0040] The first locking mechanism is used to limit the vertical bracket 2 from sliding relative to the transverse bracket 1. Specifically, the first locking mechanism can be switched between a locked state and an unlocked state. When the first locking mechanism is switched to the locked state, the vertical bracket 2 can be limited from sliding relative to the transverse bracket 1, so that the vertical bracket 2 and the transverse bracket 1 are relatively fixed. When the first locking mechanism is switched to the unlocked state, the vertical bracket 2 can slide relative to the transverse bracket 1 to adjust the distance between the vertical bracket 2 and the steering bracket.

[0041] The second locking mechanism is used to limit the rotation of the rotating bracket 3 relative to the transverse bracket 1. Specifically, the second locking mechanism can be switched between a locked state and an unlocked state. When the second locking mechanism is switched to the locked state, the steering bracket can be limited from rotating relative to the transverse bracket 1, so that the steering bracket and the transverse bracket 1 are relatively fixed. When the second locking mechanism is switched to the unlocked state, the steering bracket can be rotated relative to the transverse bracket 1 to adjust the relative angle between the steering bracket and the vertical bracket 2 in the three-dimensional space.

[0042] The third locking mechanism is used to limit the sliding and rotation of the first wire clamp 4 relative to the vertical bracket 2. Specifically, the third locking mechanism can be switched between a locked state and an unlocked state. When the third locking mechanism is switched to the locked state, the sliding and rotation of the first wire clamp 4 relative to the vertical bracket 2 can be limited, so that the first wire clamp 4 and the vertical bracket 2 are relatively fixed. When the third locking mechanism is switched to the unlocked state, the first wire clamp 4 can slide and rotate relative to the vertical bracket 2 to adjust the position of the first wire clamp 4 on the vertical bracket 2 and the installation direction of the first wire clamp 4 to the cable.

[0043] The fourth locking mechanism is suitable for limiting the sliding and rotation of the second wire clamp 5 relative to the rotating bracket 3. Specifically, the fourth locking mechanism can be switched between a locked state and an unlocked state. When the fourth locking mechanism is switched to the locked state, the sliding and rotation of the second wire clamp 5 relative to the rotating bracket 3 can be limited, so that the second wire clamp 5 and the rotating bracket 3 are relatively fixed. When the fourth locking mechanism is switched to the unlocked state, the second wire clamp 5 can slide and rotate relative to the rotating bracket 3 to adjust the position of the second wire clamp 5 on the rotating bracket 3 and the installation direction of the second wire clamp 5 on the cable.

[0044] Regarding the connection structure between the vertical support 2 and the transverse support 1 and the structure of the first locking mechanism, in this embodiment, a first slide groove 6 is provided on the transverse support 1, and the axis of the first slide groove 6 extends along the reference direction. A connecting seat 7 is provided at the end of the vertical support 2, and the connecting seat 7 is provided outside the first slide groove 6. The connecting seat 7 is located at the opening side of the first slide groove 6, and the connecting seat 7 is against the transverse support 1, such as Figure 3 shown.

[0045] The first locking mechanism comprises a first stop block 8 and a first locking member 10 .

[0046] The first stop block 8 is arranged inside the first slide groove 6, and the first stop block 8 can slide back and forth along the first slide groove 6, and the side wall of the first slide groove 6 can limit the first stop block 8 from rotating relative to the transverse bracket 1, that is, the first stop block 8 cannot rotate.

[0047] A first protrusion 9 is provided on the opening side of the first sliding groove 6 , and the first protrusion 9 can limit the first stop block 8 from escaping from the first sliding groove 6 .

[0048] The first locking member 10 is threadedly connected to the connecting seat 7 , one end of the first locking member 10 is threadedly connected to the first stop block 8 , and the other end of the first locking member 10 can abut against the connecting seat 7 .

[0049] When the first locking member 10 rotates forwardly relative to the connecting seat 7, the end of the first locking member 10 gradually approaches the bottom wall of the first slide groove 6. Since the first stop block 8 cannot rotate, the rotation of the first locking member 10 causes the first stop block 8 to move in the direction close to the opening of the first slide groove 6 until the first stop block 8 abuts against the first convex edge 9. By utilizing the extrusion force and friction force between the end of the first locking member 10 and the connecting seat 7 and the extrusion force and friction force between the first stop block 8 and the first convex edge 9, the sliding of the connecting seat 7 and the first stop block 8 relative to the first slide groove 6 can be restricted, so that the connecting seat 7 and the vertical bracket 2 are relatively fixed with the transverse bracket 1, corresponding to the locking state of the first locking mechanism. When it is necessary to switch the first locking mechanism to the unlocking state, the first locking member 10 is rotated in the opposite direction relative to the connecting seat 7 to disengage the first stop block 8 from the first convex edge 9.

[0050] The first locking member 10 may be, but is not limited to, a locking bolt. To ensure the stability and reliability of the first locking mechanism in the locked state, an anti-rotation structure such as an anti-rotation washer may be provided between the first locking member 10 and the connecting seat 7 .

[0051] In a specific embodiment, both ends of the connecting seat 7 extend to both sides of the vertical bracket 2 along the reference direction, and a group of first locking mechanisms are respectively arranged at both ends of the connecting seat 7 to ensure the locking force of the first locking mechanism on the vertical bracket 2, thereby ensuring the relative stability of the vertical bracket 2 and the transverse bracket 1.

[0052] Regarding the connection structure between the rotating bracket 3 and the transverse bracket 1 and the structure of the second locking mechanism, in this embodiment, a first connecting shaft 11 is provided on the transverse bracket 1, and the axis of the first connecting shaft 11 is provided along the reference direction. A sleeve 12 is provided at the end of the rotating bracket 3, and the sleeve 12 can allow the first connecting shaft 11 to pass through, so that the sleeve 12 is sleeved on the outside of the first connecting shaft 11, such as Figure 4 The cross-sectional shapes of the first connecting shaft 11 and the shaft sleeve 12 are both circular, so that the shaft sleeve 12 can rotate relative to the first connecting shaft 11 .

[0053] A first arc hole 13 is provided on the transverse bracket 1. The first arc hole 13 extends along an arc shape, and the arc center corresponding to the first arc hole 13 is located on the axis of the first connecting shaft 11. A second connecting shaft 14 is provided on the rotating bracket 3. The second connecting shaft 14 can pass through the first arc hole 13, and the second connecting shaft 14 can reciprocate along the first arc hole 13.

[0054] Specifically, a fixing plate 17 may be provided at one end of the transverse bracket 1 close to the rotating bracket 3 , and the first arc-shaped hole 13 may be provided on the fixing plate 17 .

[0055] The second locking mechanism includes a first fastener 15 and a second fastener 16 .

[0056] The first fastener 15 is disposed at one end of the first connecting shaft 11 away from the transverse bracket 1. The first fastener 15 is threadedly connected to the first connecting shaft 11, and the first fastener 15 can abut against the side of the sleeve 12 away from the transverse bracket 1. When the first fastener 15 rotates forward relative to the first connecting shaft 11, the first fastener 15 gradually approaches the sleeve 12 until the first fastener 15 abuts against the end surface of the sleeve 12. The extrusion force and friction force between the sleeve 12 and the transverse bracket 1 and the extrusion force and friction force between the first fastener 15 and the sleeve 12 can limit the rotation of the sleeve 12 relative to the transverse bracket 1, so that the rotating bracket 3 and the transverse bracket 1 are relatively fixed. The first fastener 15 is rotated in the opposite direction relative to the first connecting shaft 11 until the first fastener 15 is out of contact with the sleeve 12, at which time the sleeve 12 can be allowed to rotate relative to the transverse bracket 1.

[0057] The second fastener 16 is disposed at one end of the second connecting shaft 14 away from the rotating bracket 3. The second fastener 16 is threadedly connected to the second connecting shaft 14, and the second fastener 16 can abut against the side of the transverse bracket 1 away from the rotating bracket 3. When the second fastener 16 rotates forward relative to the second connecting shaft 14, the second fastener 16 gradually approaches the fixed plate 17 until the second fastener 16 abuts against the fixed plate 17. The rotating bracket 3 can be restricted from rotating relative to the transverse bracket 1 by utilizing the extrusion force and friction force between the second fastener 16 and the fixed plate 17 and the extrusion force and friction force between the fixed plate 17 and the rotating bracket 3. The second fastener 16 is rotated in the opposite direction relative to the second connecting shaft 14 until the second fastener 16 is out of contact with the fixed plate 17, at which time the rotating bracket 3 can be allowed to rotate relative to the fixed plate 17.

[0058] When the first fastener 15 is rotated to abut against the sleeve 12 and the second fastener 16 is rotated to abut against the fixing plate 17, it corresponds to the locking state of the second locking mechanism. When the first fastener 15 is rotated to disengage from the sleeve 12 and the second fastener 16 is rotated to disengage from the fixing plate 17, it corresponds to the unlocking state of the second locking mechanism.

[0059] When the second locking mechanism is in the locking state, the first fastener 15 cooperates with the second fastener 16 to increase the locking force of the second locking mechanism on the rotating bracket 3 , thereby ensuring the relative stability of the rotating bracket 3 and the transverse bracket 1 .

[0060] The first fastener 15 and the second fastener 16 may be, but are not limited to, lock nuts. To ensure the stability and reliability of the second locking mechanism in the locked state, an anti-rotation washer or other anti-rotation structure may be provided between the first fastener 15 and the sleeve 12, and an anti-rotation washer or other anti-rotation structure may be provided between the second fastener 16 and the fixing plate 17.

[0061] In this embodiment, a first angle scale mark 18 is provided on the fixing plate 17 , and the first angle scale mark 18 is used to indicate the rotation angle of the rotating bracket 3 relative to the horizontal bracket 1 and the vertical bracket 2 , so as to facilitate the adjustment of the rotation position of the rotating bracket 3 .

[0062] In the embodiment of the present invention, the first wire clamp 4 is arranged on the vertical bracket 2 through the first connecting mechanism, and the first connecting mechanism can realize the rotation and sliding of the first wire clamp 4 relative to the vertical bracket 2. The second wire clamp 5 is arranged on the rotating bracket 3 through the second connecting mechanism, and the second connecting mechanism can realize the rotation and sliding of the second wire clamp 5 relative to the rotating bracket 3.

[0063] The first connecting mechanism and the second connecting mechanism have the same structure, both of which include a mounting seat 19 and a sliding block 21. Figure 5 shown.

[0064] The mounting seat 19 is used for fixedly connecting the first wire clamp 4 or the second wire clamp 5 . A second sliding groove 20 is provided on the vertical bracket 2 , and a third sliding groove is provided on the rotating bracket 3 .

[0065] The sliding block 21 is rotatably disposed in the second slide groove 20 or the third slide groove, and the sliding block 21 can slide back and forth along the second slide groove 20 or the third slide groove. A second convex edge 22 is disposed on the opening side of the second slide groove 20, and the second convex edge 22 can limit the sliding block 21 from escaping from the second slide groove 20. A third convex edge is disposed on the opening side of the third slide groove, and the third convex edge can limit the sliding block 21 from escaping from the third slide groove.

[0066] The mounting seat 19 is located outside the second slide groove 20 and the third slide groove, and the sliding block 21 is fixedly connected to the mounting seat 19. The sliding and rotating of the sliding block 21 of the first connecting mechanism in the second slide groove 20 can realize the sliding and rotating of the first wire clamp 4 relative to the vertical bracket 2, and realize the adjustment of the position of the first wire clamp 4 and the installation direction of the first wire clamp 4 to the cable. The sliding and rotating of the sliding block 21 of the second connecting mechanism in the third slide groove can realize the sliding and rotating of the second wire clamp 5 relative to the rotating bracket 3, and realize the adjustment of the position of the second wire clamp 5 and the installation direction of the second wire clamp 5 to the cable.

[0067] The rotation axis of the sliding block 21 of the first connecting mechanism in the second sliding groove 20 serves as the rotation axis of the mounting seat 19 and the first wire clamp 4. When the first wire clamp 4 is installed on the mounting seat 19, it is necessary to ensure that the center position of the first wire clamp 4 can always be located on the rotation axis of the sliding block 21 relative to the second sliding groove 20 to avoid the rotation of the first wire clamp 4 affecting the position of the first wire clamp 4.

[0068] Similarly, the rotation axis of the sliding block 21 of the second connecting mechanism in the third slide groove serves as the rotation axis of the mounting seat 19 and the second wire clamp 5. When the second wire clamp 5 is installed on the mounting seat 19, it is necessary to ensure that the center position of the second wire clamp 5 can always be located on the rotation axis of the sliding block 21 relative to the third slide groove to avoid the rotation of the second wire clamp 5 affecting the position of the second wire clamp 5.

[0069] In this embodiment, a second arc hole 23 is provided on the mounting seat 19, and the second arc hole 23 extends along an arc. For the first connection mechanism, the arc center corresponding to the second arc hole 23 is located on the rotation axis of the sliding block 21 relative to the vertical bracket 2. For the second connection mechanism, the arc center corresponding to the second arc hole 23 is located on the rotation axis of the sliding block 21 relative to the rotating bracket 3.

[0070] The third locking mechanism and the fourth locking mechanism have the same structure, both of which include a second stop block 24 and a second locking member 25. Figure 5 shown.

[0071] The second stop block 24 is arranged inside the second slide groove 20 or the third slide groove, and the second stop block 24 can slide back and forth along the second slide groove 20 or the third slide groove, and the side wall of the second slide groove 20 can limit the second stop block 24 located in the second slide groove 20 from rotating relative to the vertical bracket 2, and the side wall of the third slide groove can limit the second stop block 24 located in the third slide groove from rotating relative to the rotating bracket 3, that is, the second stop block 24 cannot rotate in the second slide groove 20 or the third slide groove.

[0072] The second protrusion 22 can also limit the second stop block 24 in the second slide groove 20 from escaping, and the third protrusion can also limit the second stop block 24 in the third slide groove from escaping.

[0073] The second locking member 25 passes through the second arc-shaped hole 23 on the mounting seat 19 . One end of the second locking member 25 is threadedly connected to the second stop block 24 , and the other end of the second locking member 25 can abut against the mounting seat 19 .

[0074] For the third locking mechanism, when the second locking member 25 rotates forwardly relative to the vertical bracket 2, the end of the second locking member 25 gradually approaches the bottom wall of the second chute 20. Since the second stop block 24 cannot rotate, the rotation of the second locking member 25 causes the second stop block 24 to move in the direction close to the opening of the second chute 20 until the second stop block 24 abuts against the second convex edge 22. By utilizing the extrusion force and friction force between the end of the second locking member 25 and the mounting seat 19 and the extrusion force and friction force between the second stop block 24 and the second convex edge 22, the mounting seat 19 can be restricted from sliding and rotating relative to the vertical bracket 2, so that the mounting seat 19 and the vertical bracket 2 are relatively fixed, corresponding to the locking state of the third locking mechanism. When the third locking mechanism needs to be switched to the unlocking state, the second locking member 25 is rotated in the opposite direction relative to the vertical bracket 2 to disengage the second stop block 24 from the second convex edge 22.

[0075] For the fourth locking mechanism, when the second locking member 25 rotates forwardly relative to the rotating bracket 3, the end of the second locking member 25 gradually approaches the bottom wall of the third chute. Since the second stop block 24 cannot rotate, the rotation of the second locking member 25 causes the second stop block 24 to move in the direction close to the opening of the third chute until the second stop block 24 abuts against the third convex edge. By utilizing the extrusion force and friction force between the end of the second locking member 25 and the mounting seat 19 and the extrusion force and friction force between the second stop block 24 and the third convex edge, the mounting seat 19 can be restricted from sliding and rotating relative to the rotating bracket 3, so that the mounting seat 19 and the rotating bracket 3 are relatively fixed, corresponding to the locking state of the fourth locking mechanism. When it is necessary to switch the fourth locking mechanism to the unlocking state, the second locking member 25 is rotated in the opposite direction relative to the rotating bracket 3 to disengage the second stop block 24 from the third convex edge.

[0076] In an embodiment of the present invention, a second angle scale mark 26 is provided on the mounting seat 19, and the second angle scale mark 26 is used to indicate the rotation angle of the mounting seat 19 relative to the vertical bracket 2 or the rotating bracket 3, so as to facilitate the adjustment of the rotation position of the mounting seat 19, thereby facilitating the adjustment of the installation direction of the first wire clamp 4 and the second wire clamp 5 for the cable.

[0077] In this embodiment, the first wire clamp 4 and the second wire clamp 5 have the same structure, and both include a first clamping plate 27 , a second clamping plate 28 and a connecting bolt.

[0078] The first clamping plate 27 is fixedly arranged on the mounting seat 19, and a first wire groove 29 is arranged on a side of the first clamping plate 27 away from the mounting seat 19. The second clamping plate 28 is arranged on a side of the first clamping plate 27 away from the mounting seat 19, and a second wire groove 30 is arranged on a side of the second clamping plate 28 facing the first clamping plate 27. The connecting bolts are used to fix the second clamping plate 28 and the first clamping plate 27 together.

[0079] When the first clamping plate 27 and the second clamping plate 28 are fixed together, the first wire groove 29 and the second wire groove 30 are connected to form a clamping hole for the cable to pass through. When the cable is located in the clamping hole, the side wall of the first wire groove 29 and the side wall of the second wire groove 30 are pressed and contacted with the outer surface of the cable, so that the cable is fixed relative to the first clamping plate 27 and the second clamping plate 28.

[0080] The cable can be assembled and disassembled from the first wire clamp 4 or the second wire clamp 5 by screwing the connecting bolts, which is easy to operate and helps to improve the efficiency of the simulation test.

[0081] In the embodiment of the present invention, a first length scale mark is provided on the transverse bracket 1 , and the first length scale mark is used to indicate the distance between the vertical bracket 2 and the rotating bracket 3 , so as to facilitate the adjustment of the sliding position of the vertical bracket 2 .

[0082] A second length scale mark is provided on the vertical bracket 2, and the second length scale mark is used to indicate the distance between the first wire clamp 4 and the transverse bracket 1, so as to facilitate the adjustment of the sliding position of the mounting seat 19 of the first connecting mechanism on the vertical bracket 2, and to facilitate the adjustment of the position of the first wire clamp 4 on the vertical bracket 2.

[0083] A third length scale mark is provided on the rotating bracket 3, and the third length scale mark is used to indicate the distance between the second wire clamp 5 and the transverse bracket 1, so as to facilitate the adjustment of the sliding position of the mounting seat 19 of the second connecting mechanism on the rotating bracket 3 and the adjustment of the position of the second wire clamp 5 on the rotating bracket 3.
