AI Technical Summary

Technical Problem

The existing control system of the winding inclined shaft hoist cannot effectively detect the rotation of the sheave, which means that when a loose part of the wire rope falls between the drum and the sheave, the slack rope protection cannot be triggered in time, posing a potential malfunction that may lead to damage or breakage of the wire rope.

Method used

Encoders are installed on the roller and sheave. The speed is compared by the PLC integrated in the detection box. The speed difference between the roller and sheave is monitored in real time. When the difference exceeds the threshold, an alarm signal is triggered, the system decelerates or stops, and a protective sleeve protects the encoder. The detection box can be raised and lowered for adjustment.

Benefits of technology

It enables real-time monitoring of the rotational speed of the roller and sheave, promptly prevents rail jamming, protects the encoder from damage, and improves the safety and reliability of the system.
