AI Technical Summary

Technical Problem

Existing hoisting mechanisms are difficult to detect in time when wire ropes go out of the groove or become tangled, leading to safety hazards and easily causing jamming, compression deformation or breakage, which in turn can cause major safety accidents such as heavy objects falling.

Method used

Design a wire rope detachment detection device for a hoisting mechanism. Through the linkage mechanism of metal rope, contact pin and proximity switch, and by using elastic element to provide reset force, realize the physical detection and alarm of wire rope detachment. It includes the combination of metal rope, contact pin, elastic element and proximity switch to build an active safety monitoring mechanism.

Benefits of technology

It enables intuitive and reliable detection and early warning of wire rope detachment, avoids false alarms, has a stable structure and automatic reset, is easy to install, highly adaptable, can adapt to complex working conditions, and improves the safety of the hoisting mechanism.
