Description

Technical Field

[0001] This utility model relates to the field of trolley handling technology, specifically a truss transport trolley handling mechanism. Background Technology

[0002] In industrial production, handling gantry cranes are frequently used to move workpieces. A handling gantry crane typically consists of supporting beams, moving parts mounted on the beams, and transmission components connected to the moving parts. Transmission components commonly use motors and rack and pinion assemblies to transmit power; these assemblies require lubrication during use.

[0003] The existing technology CN202311403794.1, a truss manipulator for handling, or CN202011055947.4, a truss handling manipulator, is implemented by installing a movable mechanical structure on a crossbeam.

[0004] However, for trolley handling, due to its large size and weight, on the one hand, it needs to be lifted stably up and down along the top, so it needs to be effectively limited laterally and have sufficient margin; on the other hand, it needs to have strong top support and the ability to travel along the track.

[0005] To address these issues, we provide a truss transport trolley handling mechanism. Utility Model Content
