Overload prevention control device for hoisting equipment

Abstract

The invention discloses an anti-overload control device for hoisting equipment, and relates to the technical field of hoisting equipment. The anti-overload control device for the hoisting equipment comprises a protection box, a limiter body is fixedly connected to the interior of the protection box, a first baffle is rotationally connected to the left side of the protection box, a perspective window communicating with the interior of the protection box is formed in the left side of the first baffle, and a fixing groove is formed in the bottom of the first baffle. According to the anti-overload control device for the hoisting equipment, through mutual cooperation of the first baffle and the protection box, the limiter body can be better protected, and the situation that the limiter body is damaged due to the fact that external objects collide with the limiter body and pollutants such as dust in the external environment enter the limiter body is reduced to a certain extent; therefore, the service life of the limiter body is prolonged to a certain extent, and the limiter body can more smoothly carry out anti-overload control on the hoisting equipment.

Description

technical field [0001] The invention belongs to the technical field of lifting equipment, and in particular relates to an anti-overload control device for lifting equipment. Background technique [0002] Crane refers to the lifting mechanical equipment that can vertically lift and horizontally transport heavy objects within a certain range. Therefore, cranes have become an indispensable machine in various fields of industrial production. Improve the working speed of industrial production. At present, in order to prevent the electric hoist installed on the crane from being overloaded, an overload protection device is usually installed on the electric hoist. The lifting capacity limiter is a safety protection device for hoisting machinery, which is specially used for various models and specifications. Electric hoist single and double girder cranes, the device has the functions of sound alarm, immediate alarm, cutting off the hoisting motor circuit of the crane and displaying t...

AI Technical Summary

Problems solved by technology

[0003] Some current limiters are directly installed on the lifting equipment, but because the limiter is directly exposed to the external environment, it is easy for the staff to collide with the surface of the limiter when carrying items, causing damage to the limiter At the same time, dust and other pollutants in the external environment are easy to adhere to the surface of the limiter, causing damage to the limiter and reducing the service life of the limiter
