AI Technical Summary

Technical Problem

In the current descent device, the descent rope is delivered at an angle downwards when it is output from the winch to the descent section, which causes self-locking and poses a high risk.

Method used

The exit point of the descent rope in the winch and the entry point of the descent rope in the descent section are always set on the same side, and the horizontal height of the exit point of the descent rope in the winch is lower than that of the entry point of the descent rope in the descent section. The rope angle is adjusted by combining the ball screw nut pair and the rope buckle to ensure that the rope is transported parallel or obliquely upward.

Benefits of technology

This avoids the problem of the descent rope locking itself during transport, improves safety, and facilitates equipment inspection and maintenance.
