AI Technical Summary

Technical Problem

The boiler lifting platform control cabinet is seriously aging in high temperature and high ash environment. The single thermal relay protection cannot effectively monitor the motor parameters, resulting in frequent failures, affecting the maintenance progress and endangering personnel safety.

Method used

A lifting platform driving protection device is designed, including a control end and a driving motor. The motor protector detects current and transmits electrical signals. The hydraulic brake system realizes the brake of the load shaft and the driving of the protection box through calipers and brake pads to ensure that the motor is shut down and safely positioned in the event of a failure.

Benefits of technology

Effectively protect the lifting platform motor, prevent failures caused by overcurrent, overvoltage and overload, extend the service life of the motor, and improve the safety of the maintenance process, reduce fault frequency and maintenance delays.
