Hoisting steel wire rope inclined pull alarm device

Abstract

The invention discloses a hoisting steel wire rope inclined pull alarm device. The hoisting steel wire rope inclined pull alarm device comprises a signal transmitter (1) and a fixed seat (2); a connecting rod (21) for installing an adjuster (22) is arranged on the fixed seat (2); one end of the adjuster (22) is provided with a conductor surrounding the outside of a steel wire rope (9); and when the steel wire rope (9) inclines to be in contact with the conductor, a circuit of the signal transmitter (1) is connected to give an alarm. The hoisting steel wire rope inclined pull alarm device has the advantages of being simple in structure, low in manufacturing cost and wide in application range.

Description

technical field [0001] The invention relates to an alarm device for monitoring the state of a steel wire rope, in particular to a cable-stayed alarm device for hoisting a steel wire rope. Background technique [0002] When installing or dismantling large and heavy equipment in an industrial plant, due to the limitation of space and plant height, it is sometimes necessary to use hoisting equipment such as cable hydraulic hoists, electric cranes, and cranes for hoisting. During the lifting process, the wire rope in the hoisting equipment must be kept in a vertical state, otherwise the verticality is not high beyond the angle of the hoisting equipment itself, and the wire rope is easily cut off by shear force or the entire hoisting system is unstable due to excessive lateral tension. Falling will cause potential safety hazards and even safety accidents. The existing hoisting equipment basically does not monitor the state of the wire rope. The operator can only judge the vertic...

AI Technical Summary

Problems solved by technology

During the lifting process, the wire rope in the hoisting equipment must be kept in a vertical state, otherwise the verticality is not high beyond the angle of the hoisting equipment itself, and the wire rope is easily cut off by shear force or the entire hoisting system is unstable due to excessive lateral tension. Falling may cause potential safety hazards or even safety accidents

The existing hoisting equipment basically does not monitor the state of the wire rope. The operator can only judge the verticality of the wire rope based on experience, which makes the hoisting work difficult, or uses a large number of infrared sensors and laser sensors to form an array. The equipment is complicated , The cost is high. Although the instrument has high precision, it has poor anti-interference ability and poor adaptability to industrial environments. It cannot be applied to high dust and harsh environments, and its use is relatively limited.

[0003] Therefore, the existing industrial steel wire rope verticality monitoring device for hoisting equipment has the problems of complicated equipment, high cost and relatively limited use
