AI Technical Summary
Traditional hoisting equipment poses safety hazards when hoisting steel cages due to large inertial swaying of the cage and easy collision with surrounding structures. Furthermore, the fixed structure cannot adapt to the cage tilt, resulting in huge stress at the steel bar joints and damage to the cage.
The system utilizes a hydraulic cylinder and the stiffness difference between disc spring group one and disc spring group two. It achieves coaxial alignment through a centering assembly, clamping the steel cage through a clamping assembly, and locking through a positioning assembly and fixing components. The hinge between the support rod and the crossbeam allows tilting, and the arc-shaped top plate guides the support rod to be coaxial with the cage. Steel ropes provide protection.
This method enables stable hoisting of the steel cage, avoids forced deformation, protects the structural integrity of the cage, and reduces overall costs.
