AI Technical Summary

Technical Problem

The existing hoisting equipment for underground continuous wall steel cages cannot flexibly adjust the support span and hoisting point position, resulting in uneven stress, cage deformation or hoisting failure during the hoisting process.

Method used

The system employs a load-bearing mechanism, connecting components, and a hoisting mechanism. The first and second drive components drive the movement of the movable seat and the hoisting component, respectively, enabling flexible adjustment of the span and hoisting point position to meet the hoisting needs of steel cages of different lengths and reinforcement configurations.

Benefits of technology

It enables precise adjustment of the span and lifting point position of the hoisting device, reduces equipment investment costs, improves construction efficiency, avoids uneven stress and cage deformation, and ensures the stability and safety of the hoisting process.
