Test platform for wire rope tension balance wireless monitoring system calibration

Abstract

A test platform for wire rope tension balance wireless monitoring system calibration, mainly comprises a wire rope tension balance wireless monitoring system and a calibrating device; the wire rope tension balance wireless monitoring system comprises a host computer, a lower computer and a human computer interface; the calibrating device comprises a power apparatus, a roller, a wire rope, a hydraulic oil cylinder and a directive wheel, wherein the power apparatus and the roller are connected by power; the wire rope is nested in the friction liner of the roller and the directive wheel; the hydraulic oil cylinder sleeve is set on the wire rope and the control system is connected to the power apparatus and the directive wheel.

Description

technical field [0001] The invention relates to a test platform, in particular to a test platform for calibrating a wire rope tension balance wireless monitoring system. Background technique [0002] The multi-rope friction hoist uses multiple steel wire ropes to jointly bear the lifting load of the skip bucket. During long-term operation, the tension is unbalanced due to the different elastic deformation of each steel wire rope. The steel wire rope with excessive tension will first produce fatigue damage. Pads also experience excessive wear. According to Article 399 of the "Coal Mine Safety Regulations", the difference between the load and the average load of any hoisting wire rope in the friction hoisting device must not exceed ±10%. Once it is exceeded (that is, unbalanced), there is a potential danger. If it cannot be adjusted in time, a major accident may occur. Prior to this, the coal mine system could only stop production regularly for inspection and adjustment or r...

Problems solved by technology

[0004] However, in the process of long-term use, the strain elements in the wire rope and the sensor will wear out, resulting in a decrease in detection accuracy

And it can only be tested under static conditions. When not testing, the detection device must be disassembled or not stressed, otherwise it will cause damage to the test instrument or reduce the accuracy. The whole test process is very complicated.

And there is no suitable test platform for calibration of this type of sensor-equipped wire rope tension monitoring system
