AI Technical Summary

Technical Problem

Existing safety protection devices for monorail cranes have limited protective functions and insufficient impact buffering performance in complex underground environments. Furthermore, they have low reliability in braking triggering under heavy load conditions, posing risks of false triggering and damage.

Method used

A collision and derailment protection device was designed, comprising an open trigger frame, a telescopic component, and a limit switch. The telescopic component's telescopic movement and vertical in-plane swing provide dual protection against obstacle collisions and track loss. The mechanical structure prevents malfunctions and ensures the accuracy and reliability of triggering.

Benefits of technology

It achieves reliable protection for monorail cranes in dual-risk scenarios, improves the safety range and service life of the device in complex underground environments, avoids malfunctions caused by dust, moisture and electromagnetic interference, and ensures the continuity and safety of transportation.

Abstract

The invention belongs to the technical field of transportation safety of rail equipment, and particularly relates to an anti-collision and anti-derailing protection device for a monorail hoist and a using method. The device is characterized in that an open type trigger frame is mounted at the front end of the monorail hoist in the advancing direction through a trunnion; the rear end of the telescopic assembly is rotationally connected with the trunnion, and the telescopic assembly swings around the trunnion in the vertical plane. The walking trolley is rotationally installed at the front end of the telescopic assembly. The travel switch is mounted on the inner wall of the open type trigger frame; the trigger plate is fixedly arranged on the lower end face of the telescopic assembly and triggers or breaks away from the travel switch along with telescopic movement of the telescopic assembly or swing in the vertical plane. According to the invention, the telescopic movement of the telescopic assembly is utilized, and the telescopic assembly swings in the vertical surface of the trunnion, so that double reliable protection on two typical risk scenes of obstacle collision and track missing and derailing of the monorail hoist is realized, and the problem of single protection function in the prior art is solved; and the safety guarantee range of the monorail hoist in a complex underground environment is obviously expanded.
