An intelligent limit and voice alarm device for lifting equipment

Abstract

The invention relates to an intelligent limiting and voice alarm device used for hoisting equipment. The intelligent limiting and voice alarm device comprises a fixed plate. An intelligent limiter total unit is disposed on the fixed plate. The intelligent limiter total unit comprises a crooked pulling and inclined hoisting preventing device, a breaker controlling limit switch, a voice module and a fire cutoff limiter. The bottom of the fixed plate is connected to an inclined limiting top plate. A limiting Hall magnetic controller is disposed at a position close to the tail end of the limiting top plate. A limiting reporting magnetic controller is disposed below the limiting top plate. The limiting reporting magnetic controller, the breaker controlling limit switch and the limiting Hall magnetic controller are separately connected to the voice module. The intelligent limiting and voice alarm device is provided with the crooked pulling and inclined hoisting preventing device and the intelligent limiter total unit, thus preventing crooked pulling, inclined hoisting and breaking of a steel rope and lifting hook over-hoisting by the hoisting equipment.

Description

technical field [0001] The invention relates to an intelligent limit and voice alarm device for lifting equipment. Background technique [0002] Lifting equipment has become an indispensable lifting tool since the industrial revolution, occupies an important position in the national construction industry, and has also become one of the symbols of technological progress. But during the use of the enterprise, it often happens that the hook rushes to the top and the shell is flattened or the wire rope is pulled off. ②The stop limit is moved by the baffle on the rope guide to switch the fire limiter to disconnect the circuit. Because the crane operator often pulls and hangs obliquely when lifting goods, and the lifting rope Because the device cannot withstand the force of the cable pull, the steel belt is broken and invalid, and the fire limiter has become a decoration. The operator sometimes has a solidified mentality, that is, the upper limit switch, and then boldly continue...

AI Technical Summary

Problems solved by technology

The operator sometimes has a solidified mentality, that is, the upper limit switch, and then boldly continues to rise, but he does not know that the top breaks and the heavy object falls from the sky, which may easily cause personal injury or death.
