[0002] As the core logistics equipment in automated warehouses, stacker cranes are not only widely used material handling equipment within the warehouse, but also crucial equipment in logistics and warehousing systems. Travel wheels are widely used in the stacker crane's travel mechanism and are one of its core components. Traditional stacker crane travel wheels have many drawbacks, including complex structures, difficulty in repair and replacement, and an inability to compensate for installation deviations caused by manufacturing.

[0003] Most of the existing travel wheel self-locking devices are complicated and cumbersome, with large installation errors, difficulty in calibrating the travel motor installation position, low reliability, and easy loosening.

[0004] Therefore, it is necessary to design a walking wheel correction self-locking device, which has an inclined surface at a certain angle so that the resultant line of action of the main force acting on the correction self-locking device is within the friction angle, forming a self-locking device with a simple structure. Summary of the Invention

[0005] The purpose of the utility model is to provide a stacker crane walking wheel correction and self-locking device, which enables the bearing seat to have the function of left and right adjustment, so that the line of action of the resultant force of the main force acting on the correction and self-locking device is within the friction angle, and has the advantages of simple structure and easy disassembly.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0011] Four adjustment blocks are respectively arranged on both sides of the two bearing seats. The adjustment blocks are L-shaped, and the inner side surface of one side is an inclined surface that matches the inclined surface of the side surface of the bearing seat to form a wedge shape. The outer side surface of this side is fixed to the inner side surface of the front end plate and the rear end plate through a limit block; a strip hole and an adjusting screw for left and right adjustment are respectively provided on the upper and lower sides of the other side of the adjustment block, and a tightening screw hole and a tightening screw are provided between the two strip holes.

[0014] In the stacker crane walking wheel correction and self-locking device described in the utility model, two wedge-shaped adjustment blocks are designed on both sides of the bearing seat. The wedge-shaped adjustment blocks are always in close contact with the inclined surfaces on both sides of the bearing seat. By adjusting the different heights of the two adjustment blocks, the purpose of left and right displacement of the bearing seat can be achieved, and the resultant action line of the main force is within the friction angle, forming a self-locking phenomenon.
