In addition, the present invention also relates to a railway vehicle including the railway vehicle wheelset pre-assembly and adjustment device. Background Art

[0002] Conventional technology requires pre-assembly of the axle and wheel during the assembly of new or overhauled railway vehicle wheelsets. Typically, the axle is first hoisted onto a press, then the wheel is lifted by a crane and adjusted mid-air until it is inserted into the axle. This entire process occupies the crane, causing delays. Furthermore, even if each wheelset is identical in size, mid-air position adjustment still requires the crane, resulting in low efficiency. Furthermore, the entire operation requires the wheels to be suspended mid-air, posing a safety hazard.

[0003] In summary, how to reduce the difficulty of wheelset pre-assembly operations, reduce vehicle occupancy, improve operation efficiency, and ensure operation quality is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0021] In one embodiment, a threaded lifting structure is provided between the bottom of the base and the top of the first mounting seat, and two relatively distributed supporting sliders are sleeved on the threaded lifting structure. The supporting sliders are used to lift the base, and the end of the threaded lifting structure is connected to the handwheel.

[0022] A railway vehicle comprises the railway vehicle wheelset pre-assembly and adjustment device described in any one of the above items.

[0025] In summary, the railway vehicle wheelset pre-assembly and adjustment device provided by the present invention not only reduces the difficulty of wheelset pre-assembly operations and reduces vehicle occupancy, but also improves operation efficiency and ensures operation quality.

[0026] In addition, the present invention also provides a railway vehicle including the above-mentioned railway vehicle wheelset pre-assembly adjustment device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The core of the present invention is to provide a railway vehicle wheelset pre-assembly and adjustment device, which not only reduces the difficulty of wheelset pre-assembly operations and reduces vehicle occupancy, but also improves operational efficiency and ensures operational quality. Another core of the present invention is to provide a railway vehicle including the above-mentioned railway vehicle wheelset pre-assembly and adjustment device.

[0044] Please refer to Figures 1 to 3 This specific embodiment provides a railway vehicle wheelset pre-assembly adjustment device, comprising:

[0045] First mounting seat 1;

[0046] The bottom bracket 2 is parallel and liftable above the first mounting base 1;

[0047] Clamping plates 3, two clamping plates 3 are opposite and perpendicularly arranged on the base 2, and a fixing groove 31 for fixing the wheel 7 is formed between the two clamping plates 3;

[0048] Second mounting seat 4;

[0049] Support frames 5 are provided at both ends of the second mounting base 4 and are used to support the axle 8;

[0050] The base 6 has two first mounting seats 1 at both ends thereof, two second mounting seats 4 are provided between the two first mounting seats 1 , and both the first mounting seats 1 and the second mounting seats 4 are slidably provided on the base 6 .

[0051] It should be noted that the support frame 5 is used to support the axle 8. The support frame 5 can be configured as an open structure to facilitate placing the two ends of the axle 8 on the two support frames 5, respectively. The support frame 5 is also equipped with a structure for clamping and securing the axle 8 to prevent the axle 8's center of gravity from shifting to one side during assembly, causing it to tilt and thus affect the assembly of the axle 8 and wheel 7. Furthermore, both second mounting seats 4 can slide on the base 6, thereby adjusting the spacing between the two support frames 5. Ultimately, the support frames 5 slide on the sliding guide rail 61 to the appropriate position to securely support the axle 8, adapting to different axle models (with a shaft disc or gearbox). Furthermore, a baffle can be provided on the outside of the sliding guide rail 61 corresponding to the sliding area of ​​the second mounting seat 4.

[0052] Moreover, the base 6 mainly plays a bearing role. A sliding guide rail 61 is fixed to the base 6. The first mounting seat 1 and the second mounting seat 4 are both slidably mounted on the sliding guide rail 61, so that the fixing groove 31 and the support frame 5 can both translate on the sliding guide rail 61. In addition, this device is designed for all wheelset dimensions of railway vehicles. The support frame 5 can slide and adjust its position on the sliding guide rail 61, so that it can be used for wheelsets with gearboxes or axle discs, achieving a one-time design that is universal for all models. This avoids tilting and scratching when the wheel 7 is inserted into the axle 8 due to shaking and non-linear movement during driving adjustment. Therefore, this device can ensure the quality of subsequent wheelset press-fitting operations.

[0053] During actual use, the shape, structure, size, material, position, etc. of the first mounting seat 1, the base 2, the splint 3, the second mounting seat 4, the support frame 5 and the base 6 can be determined according to actual conditions and actual needs.

[0054] When using the railway vehicle wheelset pre-assembly adjustment device provided by the present invention, first, the positions of the two second mounting seats 4 can be adjusted, and then the axle 8 can be placed on the two support frames 5. The two support frames 5 are used to cooperate to support the two ends of the axle 8. Then, the position of the first mounting seat 1 can be adjusted to ensure that the two wheels 7 are respectively placed on the two first mounting seats 1 at both ends of the base 6, and to facilitate the subsequent assembly operation of the ends of the wheels 7 and the axle 8. The fixing groove 31 of the first mounting seat 1 composed of two clamping plates 3 can effectively fix the wheel 7. Afterwards, the first mounting seat 1 can be pushed to bring the wheel 7 close to the two ends of the axle 8. Subsequently, the base 2 can be controlled to move up and down relative to the first mounting seat 1 to ensure that the mounting hole of the wheel 7 and the axle 8 are aligned. Finally, continue to move the first mounting seat 1 so that the mounting hole of the wheel 7 is aligned with the end of the axle 8, completing the assembly operation of the wheel 7 and the axle 8.

[0055] This application designs a pre-assembly adjustment device for railway vehicle wheelsets. This device eliminates the need to occupy the vehicle during wheel 7 position adjustment, preventing tilting and scratching of the wheel 7 when inserted into the axle 8 due to shaking and non-linear movement during adjustment, thereby ensuring the quality of subsequent wheelset press-fitting. Furthermore, the device effectively secures the axle 8 and wheel 7, ensuring that the axle 8 and wheel 7 are free from tipping, slipping, and other safety hazards. Furthermore, the device is simple to operate, effectively reducing the difficulty of assembling the axle 8 and wheel 7, and improving operational efficiency. Furthermore, the base 2 can be raised and lowered relative to the first mounting seat 1, allowing the position of the wheel 7 to be adjusted vertically. When newly manufactured, the wheels 7 have the same dimensions, allowing for a single adjustment for long-term use. During maintenance, due to differences in wheel 7 dimensions, the base 2 can be used for fine-tuning, reducing the difficulty of assembling the wheel 7 and axle 8 and improving operational efficiency. The device is designed for all wheelset dimensions of railway vehicles, achieving a one-time design universal across all models, ensuring the quality of wheelset assembly.

[0056] In summary, the railway vehicle wheelset pre-assembly and adjustment device provided by the present invention not only reduces the difficulty of wheelset pre-assembly operations and reduces vehicle occupancy, but also improves operation efficiency and ensures operation quality.

[0057] In one embodiment, if Figure 3 As shown, the support frame 5 is provided with a V-shaped groove 51 for supporting the lower portion of the axle 8. The size and shape of the V-shaped groove 51 can be set according to the common size of the axle 8 so that the axle 8 is not easily rotated after being placed in the V-shaped groove 51, which helps to ensure the accuracy of the assembly of the wheel 7 and the axle 8 in the subsequent process.

[0058] In one embodiment, if Figure 3 As shown, the support frame 5 further includes a locking member 52 for cooperating with the V-shaped groove 51 to clamp the axle 8 .

[0059] It should be noted that the locking piece 52 and the V-groove 51 are detachably connected. When the axle 8 needs to be clamped, the operator opens the locking piece 52 to facilitate the placement of the axle 8 into the V-groove 51. When the axle 8 is placed in place and the axle 8 needs to be clamped, the operator closes and fixes the locking piece 52 to use the locking piece 52 and the V-groove 51 to clamp and fix the axle 8. When the assembled axle 8 needs to be removed, the operator opens the locking piece 52 again to facilitate the removal of the assembled axle 8 and wheel 7.

[0060] It should also be noted that the support frame 5 is provided with a V-groove 51 for supporting the axle 8 to ensure that the axle 8 does not slide. Moreover, a locking member 52 is also provided on the support frame 5 to further fix the axle 8. Both support frames 5 are arranged on the second mounting seat 4, and the second mounting seat 4 can slide on the base 6 to adjust the position, so that all models of wheelsets can be used.

[0061] In one embodiment, if Figure 9 As shown, the locking member 52 is arranged parallel to the V-shaped groove 51 through the connecting rod 53, and the locking member 52 is provided with an inverted V-shaped groove 54 for clamping the upper part of the axle 8.

[0062] It should be noted that two vertically arranged and relatively distributed pillars 55 can be provided on the second mounting base 4, and horizontal supports 56 are provided on the tops of the two supports 55. A V-shaped groove 51 is provided on the tops of the supports 56. Connecting rods 53 are vertically provided at both ends of the supports 56 (i.e., at both ends of the V-shaped groove 51). A horizontal locking member 52 is provided on the tops of the two connecting rods 53, and an inverted V-shaped groove 54 for clamping the upper portion of the axle 8 is provided at the bottoms of the locking members 52. Moreover, the tops of the two connecting rods 53 are detachably connected to the locking members 52. For example, the locking members 52 are provided with two threaded mounting holes, and the tops of the connecting rods 53 are provided with external threads. After the connecting rods 53 pass through the threaded mounting holes, they are tightened with nuts to secure the locking members 52 to the two connecting rods 53. Ultimately, the V-shaped groove 51 supports and fixes the lower portion of the axle 8, while the inverted V-shaped groove 54 clamps the upper portion of the axle 8.

[0063] In one embodiment, if Figure 4 As shown, the locking member 52 includes a first rod 57 vertically arranged on one side of the V-shaped groove 51, a second rod 58 hingedly arranged on the other side of the V-shaped groove 51, a third rod 59 hingedly arranged on the top of the second rod 58, and a fixing member 510. The end of the third rod 59 is provided with a through hole, the top of the first rod 57 is provided with an internal threaded hole, the outer periphery of the fixing member 510 is provided with an external thread, the fixing member 510 passes through the through hole and is connected to the internal threaded hole, and the bottom of the third rod 59 is used to clamp the upper part of the axle 8.

[0064] When the axle 8 needs to be placed in the V-groove 51, the operator can unfasten the fixing piece 510 and pull the third rod 59 outward to open it. At this time, the third rod 59 can pull the second rod 58 to rotate outward. After the axle 8 is placed in the V-groove 51, the operator can close the third rod 59 inward. The third rod 59 can pull the second rod 58 to rotate inward until the bottom of the third rod 59 clamps the upper part of the axle 8. At this time, the operator can pass the fixing piece 510 through the through hole and connect it to the internal threaded hole to lock the third rod 59 and the first rod 57.

[0065] In one embodiment, a handle 511 is provided on the top of the third rod 59. When the third rod 59 needs to be pulled, the operator can manually pull the handle 511 to control the opening and closing operations of the third rod 59.

[0066] In one embodiment, if Figure 7 As shown, a clamping member 32 is provided on the inner side of the clamping plate 3 along the thickness direction of the wheel 7 , and the clamping member 32 is used to contact and clamp the wheel 7 .

[0067] It should be noted that a semicircular groove 34 can be provided on the top of the clamping plate 3, and both clamping plates 3 are vertically provided on the base 2 to form a fixing groove 31 for fixing the wheel 7. When the wheel 7 is placed in the fixing groove 31, the mounting hole of the wheel 7 is completely exposed and will not be blocked by the semicircular groove 34, so as to avoid being blocked by the clamping plate 3 when the mounting hole is inserted into the end of the axle 8. In addition, a clamping member 32 can be provided on the top of one of the two clamping plates 3 of the same first mounting seat 1. For example, the clamping member 32 can be provided as a bolt structure provided perpendicular to the clamping plate 3, an elastic pad for contacting and clamping the wheel 7 is provided at one end of the bolt structure, and a knob portion for driving the bolt structure to rotate is provided at the other end of the bolt structure. In addition, a silicone pad can be provided on the side opposite to the bolt structure to cooperate with the elastic pad to clamp the end of the wheel 7.

[0068] It should also be noted that the base 2 can be raised and lowered relative to the first mounting base 1, allowing the fixing slot 31 to be adjusted vertically, ensuring that the wheel 7 is inserted into the correct position. A clamping member 32 is provided within the fixing slot 31 to secure the wheel 7 and prevent it from shifting. Furthermore, the clamping member 32 is positioned within the fixing slot 31 along the thickness of the wheel 7, preventing the wheel 7 from shaking and tilting during pre-assembly and insertion into the axle 8. Furthermore, the provision of the clamping member 32 allows for the use of wheels 7 of varying thicknesses.

[0069] In one embodiment, if Figure 6 and Figure 7 As shown, two support rollers 33 are respectively provided at both ends of the lower portion of the fixing groove 31. The support rollers 33 are rotatably disposed between the two clamping plates 3. The support rollers 33 are used to roll with the wheel 7 to adjust the unbalanced direction of the wheel 7. In other words, a rotating shaft can be provided between the two clamping plates 3 of the same first mounting seat 1, and the support rollers 33 are sleeved on the outer periphery of the rotating shaft. The support rollers 33 are located in the lower portion of the fixing groove 31. When the wheel 7 is placed on the support rollers 33, the lower portion of the wheel 7 can roll with the support rollers 33, so that the unbalanced direction of the wheel 7 can be adjusted by the support rollers 33, ensuring that the wheel 7 is properly placed.

[0070] It should be noted that the support roller 33 can be made of nylon and designed according to the LMA and LM tread profiles to ensure the stability of the wheel 7 and to rotate and adjust the imbalance direction of the wheel 7 to meet press-fit requirements. The LMA and LM tread profiles are railway-specific measuring tools used to inspect the tread shape of rolling stock wheel flanges.

[0071] In one embodiment, if Figure 4 and Figure 5As shown, a threaded lifting structure 21 is provided between the bottom of the base 2 and the top of the first mounting seat 1. Two relatively distributed supporting sliders 23 are sleeved on the threaded lifting structure 21. The supporting sliders 23 are used to lift the base 2. The end of the threaded lifting structure 21 is connected to the handwheel 22.

[0072] It should be noted that the threaded lifting structure 21 includes a screw elevator (which is placed horizontally in this application, that is, when the worm wheel rotates, the screw moves horizontally to the left and right, driving the support slider 23 to move back and forth laterally). The screw elevator mainly includes components such as a worm gear, a housing, bearings, and a screw. The worm gear, as the core transmission component, engages with each other to achieve power transmission and deceleration, amplifying the thrust through the deceleration effect, making the lifting smoother and more powerful. The housing is used to protect the internal transmission components and prevent damage such as dust. It also has a certain load-bearing capacity to ensure lifting stability. The bearings are installed on the screw to reduce friction and wear, and improve transmission efficiency and service life. The screw is a key component for realizing lifting motion. It cooperates with the internal thread of the worm wheel cavity. When the worm wheel rotates, the screw moves up and down along the axial direction, driving the support slider 23 to lift and lower. However, in this application, the screw is placed horizontally, so that when the worm wheel rotates, the screw moves left and right, driving the support slider 23 to move back and forth laterally.

[0073] When the position of the wheel 7 needs to be adjusted, the operator can manually rotate the handwheel 22. When the handwheel 22 drives the worm to rotate, the worm drives the worm wheel to rotate at a reduced speed. The internal threads of the worm wheel cavity cooperate with the external threads of the lead screw to form a spiral transmission. As the worm wheel rotates, the horizontally placed lead screw moves axially, driving the support slider 23 to achieve horizontal reciprocating movement. When the two support sliders 23 are close to the center position, the base 2 can be raised relative to the first mounting seat 1. When the two support sliders 23 are away from the center position, the base 2 can be lowered relative to the first mounting seat 1.

[0074] In addition to the above-mentioned railway vehicle wheelset pre-assembly adjustment device, the present invention also provides a railway vehicle including the railway vehicle wheelset pre-assembly adjustment device disclosed in the above-mentioned embodiment. For the structures of other parts of the railway vehicle, please refer to the prior art and will not be described in detail herein.

[0075] It should be noted that the first mounting seat 1 and the second mounting seat 4 mentioned in this application document are only used to distinguish the difference in position and there is no order of precedence.

[0076] In addition, it should be noted that the orientation or position relationship indicated by "bottom" and "top" in this application is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of simplifying the description and facilitating understanding, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
