Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, specifically a cam platform lifting device. Background Technology

[0002] A document with publication number CN108529483A discloses a handling robot for a warehousing and logistics system. The robot includes a vehicle body, which comprises a base plate and drive wheels and driven wheels mounted on the base plate. The vehicle body is equipped with a lifting and rotating unit and an environmental detection unit. The lifting and rotating unit includes a lifting platform with a rotating pallet that can be controllably rotated relative to it. The lifting and rotating unit also includes at least one set of drive components for lifting the lifting platform, and the lifting components include lifting blocks fixedly mounted on the base plate. The handling robot in this warehousing and logistics system achieves the lifting and lowering of the rotating pallet through the cooperation of the lifting surface on the lifting block and the cam pair of the cam follower. The rotation of the rotating pallet is achieved through the meshing of a large gear and a small gear. The structure is stable and reliable, enabling the handling of goods on shelves.

[0003] In logistics and cargo handling, the above-mentioned solutions and existing technologies often use cam platform lifting control mechanisms. During lifting control, the motor typically drives the cam to rotate, and the cam then passes through a pressure rod. The pressure rod uses the lever principle to lift the platform. The bottom of the cam platform lifting mechanism is usually fastened with simple bolts. During operation, these bolt connections are prone to loosening, affecting the stability of the lifting operation. Existing cam platform lifting mechanisms lack corresponding position stabilizing accessories to meet their stable operation requirements.
