AI Technical Summary

Technical Problem

The existing emergency stop devices for suspended personnel carriers have problems such as cable jamming, cable breakage, and unreliable contact due to easily damaged limit switches. They require manual pulling to stop, which may lead to safety accidents.

Method used

An infrared diffuse reflection emergency stop device is adopted, which combines an infrared switch and a relay. The transmitter and receiver are installed below the emergency stop cable. The relay is triggered by the infrared signal to disconnect the motor starter, thereby realizing automatic emergency stop.

Benefits of technology

It avoids the limitations of mechanical structures, features automatic emergency stop to prevent safety accidents, is simple to install, reliable and practical, and solves problems such as broken pull wires and malfunctioning limit switches.
