AI Technical Summary

Technical Problem

Existing methods for transporting arch frames are limited in operation in narrow spaces, have low precision, are costly, and pose safety hazards. Traditional hoisting equipment is unable to meet the stability and safety requirements of tunnel construction.

Method used

The design employs a front and rear grab arm, combined with a transfer carriage and storage rack, to achieve stable transfer of the arch frame. Through the cooperation of the sliding mechanism and guide components, the rotation of the robotic arm is prevented, the grab arm length and stability are increased, and the smooth movement of the arch frame in the tunnel is ensured.

Benefits of technology

It improves the stability and safety of arch frame transportation, expands the construction scope, reduces equipment costs, and reduces operational complexity and adjustment time.
