Description

Technical Field

[0001] This utility model relates to the field of wheelset lifting equipment technology, and in particular to a wheelset lifting equipment. Background Technology

[0002] Currently, wheelsets, which are widely maintained in railway locomotive depots and rolling stock depots, are key components of locomotives and rolling stock. Their quality directly affects train operation safety. Locomotive and rolling stock wheelsets are large in size and heavy in weight. During the assembly into bogies, they need to be lifted and transported multiple times. It is required that the wheelsets remain stable during lifting or transportation and that there is no large swaying. The lifting tools should not damage the journal or axle body surface structure to affect the surface roughness. The operation should be convenient, and one person can complete the lifting or transportation task.

[0003] Patent document CN117923307A discloses an adaptive adjustable wheelset lifting device, relating to the field of wheelset lifting technology. It includes a crossbeam with lifting lugs, two lifting rods mounted on the crossbeam, and two hanging parts respectively mounted on the lower ends of the two lifting rods. The hanging parts are used to support the object being lifted. It also includes an internal contact adjustment unit for automatically adapting to wheelsets of different lengths and for contact positioning of the inner sides of the two wheels on the wheelset. This invention has a reasonable structure and an internal contact adjustment unit that automatically adapts to wheelsets of different lengths, avoiding the unnecessary trouble caused by manual or electric adjustments. Simultaneously, it automatically contacts and positions the inner sides of the two wheels on the wheelset, ensuring good stability of the wheelset during suspended lifting, preventing it from falling off the lifting device, and providing high safety.

[0004] While the aforementioned application can guarantee good stability and prevent the device from falling off the lifting device during use, thus ensuring high safety, its complex structure and high operating costs in actual application have prevented its widespread use in railway locomotive depots and rolling stock depots. This has affected the normal lifting operation of the lifting device and made it inconvenient for subsequent normal use. Utility Model Content

[0005] This utility model discloses a wheelset lifting device, which aims to solve the technical problems mentioned in the background art.

[0016] In a preferred embodiment, a slot is provided on one side of the hook for the arc-shaped plate to be engaged, and the inner wall of the slot is in contact with the surface of the arc-shaped plate. A protective plate is fixedly installed on the inner side of the hook, and a reinforcing rib is fixedly installed on the outer side of the hook.

[0017] The protective plate prevents friction between the surface of the shaft and the inside of the hook during use, reducing wear on the shaft surface and facilitating subsequent hoisting operations.

[0018] In a preferred embodiment, a threaded hole for threaded connection of a screw is provided on one side of the support rod, and a compression block is fixedly installed at one end of the screw. The compression block is made of rubber, and an anti-slip ring is fitted on one end of the limit rod on the surface of the screw. One side of the anti-slip ring is in contact with one side of the support rod.

[0019] By setting up the compression block, the screw can be easily compressed and positioned, thus maintaining the positioning stability of the screw.

[0020] In a preferred embodiment, a tube hole is provided on one side of the limiting rod, a compression spring is fixedly installed on one side of the inner wall of the tube hole, and a sliding block is fixedly installed on one end of the compression spring. The surface of the sliding block is slidably connected to the inner wall of the tube hole.

[0021] The compression spring allows the sliding block to be reset by its own weight during use, facilitating subsequent positioning and compression.

[0022] In a preferred embodiment, a hemispherical block is fixedly mounted on one side of the sliding block, and a gap is left between one side of the hemispherical block and one side of the limiting rod.

[0023] The hemispherical block allows for easy compression of one side of the wheel during use, thus maintaining the stability of the lifting device during installation.

[0024] As can be seen from the above, the wheelset lifting device provided by this utility model has the following technical effects.

[0025] Firstly, the hook limiting component allows the spreader to be secured to the wheelset axle during use, preventing the spreader from loosening after engagement. Furthermore, this simple structure has low operating costs and can be widely used in railway locomotive depots and rolling stock depots, facilitating normal lifting operations and subsequent use.

[0026] Secondly, the limit adjustment component allows for easy compression of the inner sides of the wheels on both sides of the wheelset during use, thus preventing the wheels from rotating during lifting and maintaining the stability of the lifting device while also ensuring the fit between the lifting device and the wheelset.

The hanger 1 is inverted U-shaped, and the two sides of the inner wall of the hanger 1 are fixedly connected by reinforcing rods 204. A support plate 205 is fixedly installed on the top side of the reinforcing rods 204. One side of the support plate 205 is fixedly connected to one side of the hanger 1. The reinforcing rods 204 and the support plate 205 facilitate the connection and positioning of the hanger 1 during use, thereby increasing the stability and firmness of the hanger 1 and preventing damage to the hanger 1 during use.

[0035] The hook limiting component 2 can lock the lifting device onto the wheel axle during use, preventing the lifting device from loosening after locking. This simple structure has low operating costs and can be widely used in railway locomotive depots and rolling stock depots, facilitating normal lifting operations and subsequent use. A slot for the arc-shaped plate 201 to engage is provided on one side of the hook 200, with the inner wall of the slot contacting the surface of the arc-shaped plate 201. A protective plate 207 is fixedly installed on the inner side of the hook 200, and a reinforcing rib 208 is fixedly installed on the outer side of the hook 200. The protective plate 207 prevents friction between the surface of the axle and the inner side of the hook 200 during use, reducing wear on the axle surface and facilitating subsequent lifting operations.

[0036] The limit adjustment assembly 3 includes support rods 300 fixedly installed on both sides of the hanger 1. One end of the support rod 300 is threadedly connected to a screw 301, and one end of the screw 301 is fixedly installed with a limit rod 302. A rotating rod 303 is threadedly connected to the surface of the limit rod 302. A triangular plate 206 is fixedly installed on one side of the bottom of the support rod 300, and one side of the triangular plate 206 is fixedly connected to one side of the hanger 1. An anti-slip sleeve 304 is sleeved on the surface of the rotating rod 303, and the inner wall of the anti-slip sleeve 304 is fixedly connected to the surface of the rotating rod 303. The triangular plate 206 increases the stability of the connection between the support rod 300 and the hanger 1 during use. The anti-slip sleeve 304 facilitates the rotation of the rotating rod 303, making subsequent use easier. A threaded hole for threaded connection of the screw rod 301 is provided on one side of the support rod 300. A compression block 305, made of rubber, is fixedly installed at one end of the screw rod 301. An anti-slip ring 306 is fitted onto the surface of the limit rod 302 at one end of the screw rod 301. The side of the screw 301 is fitted against one side of the support rod 300. The compression block 305 facilitates the compression and positioning of the screw 301, thus maintaining the positioning stability of the screw 301. A tube hole is opened on one side of the limiting rod 302. A compression spring 307 is fixedly installed on one side of the inner wall of the tube hole. A sliding block 308 is fixedly installed on one end of the compression spring 307. The surface of the sliding block 308 is slidably connected to the inner wall of the tube hole. The compression spring 307 can reset the sliding block 308 by its own weight during use, thus facilitating subsequent... Continuing the positioning and pressing, a hemispherical block 309 is fixedly installed on one side of the sliding block 308. A gap is left between one side of the hemispherical block 309 and one side of the limiting rod 302. The hemispherical block 309 is set to facilitate pressing one side of the wheel during use, thereby maintaining the installation stability of the lifting device. The limiting adjustment component 3 is set to facilitate pressing the inner side of the wheels on both sides of the wheelset during use, thereby preventing the wheels from rotating during lifting and maintaining the stability of the lifting device during lifting, while also maintaining the fit between the lifting device and the wheelset.

[0037] Working principle: When hoisting is required, the hook 200 on the lifting device is fixed to the connecting part of the hoisting equipment. Then, the hook 200 is hung on the axle of the wheel set. As the axle engages with the hook 200, it presses against the arc plate 201, causing the arc plate 201 to move inward. When the axle separates from the arc plate 201, the return spring 203 resets the arc plate 201, making it fit against one side of the hook 200. This prevents the axle from separating from the hook 200 during use. Then, the rotating rod 303 on the anti-slip sleeve 304 is rotated. The rotating rod 303 drives the screw 301 on the limit rod 302 to rotate, thereby adjusting the distance between the support rod 300 and the limit rod 302. This causes one side of the hemispherical block 309 to press against one side of the wheel, facilitating subsequent limiting operations and preventing loosening during hoisting.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
