AI Technical Summary

Technical Problem

The existing helicopter maintenance platform lacks flexible support for tools and equipment, which requires maintenance personnel to frequently go up and down the platform to retrieve tools, increasing manpower consumption and reducing work efficiency.

Method used

A structure including an inspection frame, a fixed frame, a motor, a sprocket, a chain, a sliding block, a hollow frame, a support plate, a tool frame, and a guide rail is designed. The motor drives the chain to move the sliding block and the hollow frame, and the support plate drives the tool frame to slide on the guide rail, realizing automatic tool delivery and reducing the need for personnel to go up and down the platform.

Benefits of technology

It enables automatic tool delivery, reduces the physical exertion of maintenance personnel, improves work efficiency, and ensures the stability and safety of the maintenance platform through the cooperation of hydraulic cylinders and casters.
