Technical Field
[0001] This utility model relates to the field of stacker crane maintenance technology, specifically to an auxiliary tool for changing the traveling wheels of a stacker crane. Background Technology
[0002] Stacker cranes are crucial pieces of machinery in automated warehousing systems, designed for high-density storage and efficient goods retrieval. They typically run along tracks between racks, using liftable forks to precisely place goods at designated levels on the racks or quickly retrieve goods from them. With advanced electrical control systems and precise positioning technology, stacker cranes can achieve unmanned and automated operation, significantly improving warehouse space utilization and goods turnover efficiency. They are widely used in modern intelligent warehousing scenarios in e-commerce, logistics, manufacturing, and other fields.
[0003] However, during the use of stacker cranes in smart warehouses, after prolonged operation, the wheels of the stacker cranes tend to experience significant wear and tear, with severe peeling of the tread surface. Analysis indicates this is a problem with the quenching process, necessitating the replacement of the wheels. In existing technologies, the wheels are often manually hammered out. However, this often fails to find a suitable stress point, resulting in ineffective hammering and excessively long replacement times, preventing timely removal of parts and reducing production capacity. Furthermore, manual hammering can easily damage components. Therefore, we propose an auxiliary tooling for replacing stacker crane wheels. Utility Model Content
[0004] One of the technical problems this application aims to solve is: addressing the issue that after prolonged use, the wear and tear on the wheels of a stacker crane leads to excessively long replacement times, resulting in decreased productivity and potential damage to components.

A connecting plate is fixedly connected to one side surface of the upper end of the mounting frame. A rotating rod is movably connected to one side of the mounting frame. A linkage wheel is fixedly connected to one side surface of the rotating rod. A bushing outer wheel is sleeved to the outer side of the linkage wheel. A hollow groove is formed on the inner side of the mounting frame. The linkage wheel and the bushing outer wheel are disposed inside the hollow groove. A through hole is formed on one side surface of the mounting frame. A threaded rod is movably connected inside the through hole. A square plate is movably connected to one end of the threaded rod. A threaded groove is formed on one side surface of the square plate. Two threaded grooves are provided and are symmetrically and evenly distributed.
[0006] Preferably, two square plates are provided and distributed parallel to the direction of the threaded rod. A snap-fit plate is provided between the two square plates. Snap-fit grooves are provided on both sides of the snap-fit plate, and the snap-fit grooves are adapted to the outer side of the square plates.
[0007] Preferably, the two square plates are snapped together on the inner side of the two snap-fit grooves.

One end of the square plate on the outer side is provided with a limiting washer. One end of the limiting washer is movably connected to a nut. Both the limiting washer and the nut are movably connected to one end of the threaded rod.
[0008] Preferably, a first limiting block is fixedly connected to one side surface of the snap-fit plate, and two first limiting blocks are provided. A lifting groove is opened on one side surface of the snap-fit plate, and a second limiting block is movably connected to the inner side of the lifting groove. A spring is fixedly connected to one side surface of the second limiting block, and one end of the spring is fixedly connected to one end of the lifting groove. Two sets of lifting grooves and two sets of second limiting blocks are provided.
[0009] Preferably, a jack is provided on one side of the snap-fit plate, a conical push block is fixedly connected to the output end of the jack, an annular block is fixedly connected to one side surface of the mounting bracket, one end of the conical push block is snapped into the inside of the annular block, and a lever is fixedly connected to one end of the jack.

[0012] This utility model has at least the following beneficial effects:
[0013] 1. This utility model stabilizes the positions of two square plates and a snap-fit plate using a threaded rod. At the same time, the first and second limiting blocks on the side of the snap-fit plate stabilize the position of the jack. Meanwhile, the annular block precisely positions the conical push block at the output end of the jack. Then, using the thrust of the jack, the linkage wheel can be pushed out of the installation position smoothly and accurately without the need for manual hammering. This greatly improves the efficiency of replacing the traveling wheel, reduces labor intensity, and avoids damage to other parts of the stacker crane that may be caused by hammering.

A threaded groove 16 is provided on one side surface of the square plate 15. There are two threaded grooves 16, which are symmetrically and evenly distributed. The through hole 13 is used to stabilize the placement and use of the threaded rod 14. At the same time, a groove that matches the outer side of the threaded rod 14 is provided inside the through hole 13. When the threaded rod 14 passes through the inside of the through hole 13, it can effectively guide and stabilize the movement direction and position of the threaded rod 14.
[0025] Two square plates 15 are provided and are distributed parallel to each other along the direction of the threaded rod 14. A snap-fit plate 17 is provided between the two square plates 15. Snap-fit grooves 18 are provided on both sides of the snap-fit plate 17. The snap-fit grooves 18 are adapted to the outer sides of the square plates 15. The two square plates 15 can be snapped onto the sides of the snap-fit plate 17 using the snap-fit grooves 18. The snap-fit plate 17 is used to widen the space at this position, facilitating the connection between one side of the snap-fit plate 17 and the jack 23, thereby facilitating the overall use of the device.
[0026] Two square plates 15 are snapped together on the inner side of two snap-fit grooves 18. Two symmetrically distributed through slots are provided on one side of the snap-fit plate 17. The positions of the two slots correspond to the threaded grooves 16 opened on one side of the square plate 15. A limiting washer 27 is provided at one end of the square plate 15 on the outer side. A nut 28 is movably connected to one end of the limiting washer 27. Both the limiting washer 27 and the nut 28 are movably connected to one end of the threaded rod 14. The use of one limiting washer 27 and two nuts 28 at one end of the threaded rod 14 limits the placement position of the square plate 15.
[0027] A first limiting block 19 is fixedly connected to one side surface of the snap-fit plate 17. There are two first limiting blocks 19. A lifting groove 20 is opened on one side surface of the snap-fit plate 17. A second limiting block 21 is movably connected to the inner side of the lifting groove 20. A spring 22 is fixedly connected to one side surface of the second limiting block 21. One end of the spring 22 is fixedly connected to one end of the lifting groove 20.

An annular block 25 is fixedly connected to one side of the mounting bracket 1. One end of the conical push block 24 is snapped into the inside of the annular block 25. A toggle rod 26 is fixedly connected to one end of the jack 23. The annular block 25 is used to limit the conical push block 24 fixedly connected to the output end of the jack 23, so that it is stably set on one side of the linkage wheel 4 that needs to be pushed.
[0029] The lower end of the mounting bracket 1 is provided with a moving rail 6. The moving rail 6 has embedded grooves 7 on both sides. An outer plate 8 is fixedly connected to one side surface of the mounting bracket 1. There are two outer plates 8, which are symmetrically distributed. A guide wheel 9 is movably connected to one side surface of the outer plate 8. The two guide wheels 9 are movably locked inside the embedded grooves 7. The outer surface of the guide wheel 9 is in contact with the inner surface of the embedded groove 7. By using the cooperation between the two guide wheels 9 and the embedded grooves 7 on both sides of the moving rail 6, the mounting bracket 1 and related components are kept in a stable state when moving on the upper end of the moving rail 6.
[0030] An auxiliary bearing 11 is fixedly connected to the outer side of the rotating rod 3. A connecting plate 10 is fixedly connected to the upper end of the auxiliary bearing 11. One side of the connecting plate 10 is fixedly connected to the lower end of the connecting plate 2. The connecting plate 10 is used to fix the overall position of the auxiliary bearing 11. At the same time, the auxiliary bearing 11 facilitates the synchronous movement of the rotating rod 3 and some components associated with the rotating rod 3 by an external control device. The external control device refers to the control and linkage device used to drive the rotating rod 3 to rotate. It belongs to the prior art and will not be described in detail here. An arched groove 29 is provided at the lower end of the mounting frame 1. The arched groove 29 is arched in shape to facilitate the stable movement of the moving rail 6 at the lower end of the mounting frame 1 when the whole is moved, so as to avoid the situation of offset and misalignment.
[0031] When replacing the stacker crane's traveling wheels, first place the auxiliary tooling in a suitable position. Move the end of the mounting frame 1, which has the linkage wheel 4 and the bushing outer wheel 5, to the outermost side of the moving rail 6, so that the outer surface of the bushing outer wheel 5 is no longer in contact with the upper end of the moving rail 6. Then, pass the threaded rod 14 through the through hole 13 on one side of the mounting frame 1, and fix the position of the passed end using the limiting washer 27 and nut 28. Then, install a square plate 15, a snap-fit plate 17, and another square plate 15 sequentially from the other end of the threaded rod 14. Then, install a limiting washer 27 and two nuts 28 on one side of the square plate 15 located on the outer side. Then, according to the installation direction requirements of the jack 23, place one end of the jack 23 on one side surface of the snap-fit plate 17. Utilize the cooperation between the first limiting block 19 and the second limiting block 21 on one side of the snap-fit plate 17 to achieve... The jack 23 is limited at one end and fixed to one side of the snap-fit plate 17. The conical push block 24, which is fixedly connected to the output end of the jack 23, is stably snapped into the inner side of the annular block 25 set on one side of the mounting frame 1, so that the whole is accurately positioned. Then, by operating the jack 23, the conical push block 24 at its output end acts on one side of the linkage wheel 4, pushing the linkage wheel 4 out from one side of the mounting frame 1. At the same time, the linkage wheel 4 and the outer wheel of the bushing 5 are disengaged. The outer wheel of the bushing 5 is taken out from the hollow groove 12. Then, the linkage wheel 4 and the outer wheel of the bushing 5 are replaced as needed, and the whole is reset. The whole is disassembled and replaced. After the installation is completed, the arched groove 29 at the lower end of the mounting frame 1 is adapted to the moving rail 6, and the two guide wheels 9 are accurately snapped into the embedded grooves 7 on both sides of the moving rail 6, so that the mounting frame 1 is accurately reset and the whole can move smoothly.
