Problems solved by technology

[0002] In the existing domestic lifting equipment or elevator elevator equipment, vicious accidents caused by sudden breakage of wire ropes occur from time to time, which not only cause serious economic losses to enterprises or individuals, but also cause serious casualties
The current protection devices are basically based on detecting the use status of the wire rope or directly replacing the wire rope on a regular basis. These methods not only have hysteresis, but also have a relatively low safety factor and low reliability. In addition, regular replacement of the wire rope will inevitably lead to waste. The used steel wire rope has to be scrapped in advan

Abstract

The invention provides a cut cable protection device (100) and a hoisting equipment provided with the same (10); the cut cable protection device (100) is used for carrying a main mechanism cable (18) of a workpiece (20), wherein, the protection device (100) comprises a tension sensor (30) and a protection drum (40), the tension sensor (30) is connected to the main mechanism cable (18) and senses the tension of the main mechanism cable (18), the protection drum (40) is driven by a rotating shaft (42) and comprises a cable part (44) and a first brake piece, the cable part is winded with a protection cable (46), and the end of the cable part (44) is connected to the workpiece (20); a second brake piece is arranged near the first brake piece, responds to the preset sensing signal of the tension sensor (30) and joints with the first brake piece to brake the protection drum (40). By using the protection device, the safety of operation when the main mechanism cable is cut can be guaranteed, thus greatly improving the reliability of the hoisting equipment and effectively avoiding occurrence of severe accidents.

Description

technical field [0001] The present invention relates to a protective device and a lifting device with the protective device, in particular, the present invention relates to the use of flexible cables or chains in hoisting mechanisms, luffing mechanisms, traction operating mechanisms or other similar flexible cables or chains. A device that protects the chain when the chain breaks. Background technique [0002] In the existing domestic lifting equipment or elevator elevator equipment, vicious accidents caused by sudden breakage of steel wire ropes occur from time to time, which not only cause serious economic losses to enterprises or individuals, but also cause serious casualties. The current protection devices are basically based on detecting the use status of the wire rope or directly replacing the wire rope on a regular basis. These methods not only have hysteresis, but also have a relatively low safety factor and low reliability. In addition, regular replacement of the wi...
