Description

Technical Field

[0001] This utility model relates to the field of heavy-duty stacker crane technology, and in particular to a lifting guide wheel mechanism suitable for heavy loads. Background Technology

[0002] Heavy-duty stacker cranes are specialized cranes that use rails to limit their movement range and employ forks or booms as picking devices to move back and forth between racks or warehouses to grab, transport, and stack goods, or to retrieve unitized goods from high-level racks. Heavy-duty stacker cranes operate within the aisles of automated warehouses, storing goods located at aisle entrances into rack compartments, or retrieving goods from compartments and transporting them to aisle entrances. The lifting guide wheel mechanism guides and supports the vertical movement of the loading platform. The lifting guide wheel mechanism includes a mounting bracket and guide wheel assemblies, which are fixed to the mounting bracket via a shaft connection and contact the surface adjacent to the guide rail.

[0003] The lifting guide roller device is designed to ensure the stability and safety of the stacker crane during vertical lifting. By adjusting the gap between the guide roller and the guide rail in real time, this gap will not change even during long-term operation, thus ensuring the normal operation and safety of the stacker crane.

[0004] The stacker crane lifting guide wheel device is mainly used in automated warehouses and logistics systems. However, the following problems may arise in actual operation:

[0005] Traditional technology involves directly connecting the guide wheels to the mounting bracket via an eccentric shaft, with each wheel contacting one of the two adjacent sides of the guide rail. This design increases the stress on the diagonal guide wheels when loading and unloading goods, thus reducing their lifespan. Larger guide wheels are then selected, leading to increased costs. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a lifting guide wheel mechanism suitable for heavy loads, so as to solve the current technical problem that causes the diagonal guide wheels of the loading platform to be subjected to increased force when picking up and placing goods, thereby reducing the service life.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A lifting guide wheel mechanism suitable for heavy loads includes a heavy-duty stacker crane, wherein a cargo loading mechanism is fixedly mounted on the inner surface of the heavy-duty stacker crane via a drive device.

[0010] The cargo-carrying mechanism includes a mounting bracket, the outer surface of which is slidably connected to the inner surface of the heavy-duty stacker crane, a fixed shaft is fixedly mounted on the top of the mounting bracket, and a cargo platform is fixedly mounted on the front of the mounting bracket.

[0011] As an improved technical solution, the cargo-carrying mechanism further includes a mounting base plate, the bottom of which is fixedly connected to the top of the mounting bracket, and the inner surface of which is rotatably connected to the outer surface of the fixed shaft.

[0012] As an improved technical solution, the cargo-carrying mechanism further includes a pressure block, the inner surface of which is rotatably connected to the outer surface of the fixed shaft.

[0013] As an improved technical solution, the cargo-carrying mechanism also includes a special bolt, the outer surface of which is threadedly connected to the inner surface of the pressure block, and a disc spring is sleeved on the outer surface of the special bolt.

[0014] As an improved technical solution, the cargo-carrying mechanism further includes a guide wheel, the inner surface of which is rotatably connected to the outer surface of the fixed shaft.

[0015] As an improved technical solution, the cargo-carrying mechanism further includes a blocking block, the bottom of which is fixedly connected to the top of the mounting base plate.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] This invention utilizes the cooperation between the fixed shaft and the mounting base plate, the pressure block, the special bolts, and the disc spring, and the guide wheel and the blocking block in conjunction with the pressure block. This allows the guide wheel on one side of the cargo platform to be stressed when picking up goods, causing the pressure block to press against the disc spring and the blocking block to adhere to the guide rail. This ensures that the force is applied to the pressure block, reducing wear on the guide wheel, thereby increasing the service life of the guide wheel and reducing subsequent maintenance costs.
