Wire rope online flaw detection monitoring system, method and mining multi-rope friction lifting system

Abstract

The invention relates to an online flaw detection monitoring system and an online flaw detection monitoring method for steel wire ropes and a mining multi-rope friction hoisting system. The online flaw detection monitoring system comprises a flaw detection sensor, a communication module and a computing and processing device. The flaw detection sensor is arranged around the to-be-detected steel wire ropes and is used for acquiring defect signals of the steel wire ropes in real time; the communication module is used for converting the defect signals of the steel wire ropes and transmitting converted defect signals to the computing and processing device; the computing and processing device is used for extracting fault characteristic values from the converted defect signals and searching steel wire rope fault categories from preset fault characteristic libraries, and the steel wire rope fault categories correspond to the fault characteristic values. The online flaw detection monitoring system, the online flaw detection monitoring method and the mining multi-rope friction hoisting system have the advantages that the defect signals of the detected steel wire ropes are converted, the fault characteristic values are extracted, the steel wire rope fault categories which correspond to the fault characteristic values are searched from the preset fault characteristic libraries, accordingly, damage types of the steel wire ropes can be accurately judged while flaw detection is carried out on the steel wire ropes, and operators can conveniently timely check and repair faults.

Description

technical field [0001] The invention relates to the field of flaw detection, in particular to a steel wire rope online flaw detection monitoring system and method, and a mining multi-rope friction lifting system. Background technique [0002] For the mine hoist, the wire rope suspension device is an important device for the normal operation of the hoist. The wire rope may be damaged during use. If the damage and the location of the damage cannot be found in time, it may lead to a broken rope accident. [0003] The Chinese invention patent application with the publication number CN104569143A discloses an on-line monitoring system for mine steel wire rope flaw detection. A sensor driven by a detection frame is provided. The detection frame is erected on the support and can move along its slideway. The detection frame is connected with the system console to control the sensor to hug the detected steel wire rope. This system cannot solve the impact of the vibration of the stee...

Problems solved by technology

However, this scheme cannot judge the damage type of the wire rope, and requires the operator to judge the damage of the wire rope based on experience or actual observation of the damaged part of the wire rope after learning that the wire rope has been damaged, and the practicability still needs to be improved.

In this scheme, the traditional encoder is used for speed detection, but the accuracy of the detected speed is low because the steel wire rope is prone to slipping during use
