AI Technical Summary

Technical Problem

The existing shore ladder winding mechanism suffers from uneven winding of the steel cable on one side, resulting in difficult winding and easy damage. It is also difficult to wind the steel cables on both sides at the same time, which affects the stability of the traveling bridge.

Method used

A dual-guide mechanism and a limiting port structure are designed to guide and separate the two steel cables onto the same take-up drum, ensuring that the steel cables do not cross or tangle. Stable winding and unwinding are achieved by driving the take-up drum through a rocker arm.

Benefits of technology

This technology enables the simultaneous and stable deployment and retraction of two steel cables, preventing jamming and improving the stability of the traveling bridge and the service life of the winding mechanism.
