Method for detecting operation troubles of mine hoist

Abstract

The invention relates to a method for detecting operation troubles of a mine hoist. The method comprises the following steps of: axially arranging a wireless stress sensor on a hoisting sheave shaft or a guide wheel shaft, wherein the wireless stress sensor is used for acquiring a stress-strain signal on the shaft and transmitting the stress-strain signal to an industrial personal computer through a wireless signal receiving device; identifying peaks and troughs of the stress-strain signal to acquire a real-time hoisting speed curve and a hoisting container depth curve by a mine hoist operation trouble detection module in the industrial personal computer, simultaneously converting the stress-strain signal according to a corresponding relationship between the stress-strain signal and a hoisting load to acquire a real-time hoisting load curve; and judging whether phenomena such as over-winding, over-unwinding, slipping, cage clamping, rope releasing, overloading and the like exist or not by combining the hoisting speed curve given by the hoist, rated load and the reading of a depth indicating meter on the basis of the acquired three real-time curves. The method has the advantages ofsimple required hardware equipment, high reliability, high anti-interference performance, high real time property and capacity of detecting various troubles simultaneously.

Description

technical field [0001] The invention relates to a method for detecting the operation of a hoist, in particular to a method for detecting operation faults of a mine hoist. Background technique [0002] In the mine produced by the vertical shaft, the hoist is the throat equipment of the entire mine, and its operation status directly affects the safe production of the mine. However, during the operation of the hoist, faults such as high-speed overwinding and over-discharging, can jamming, loose rope and slippage sometimes occur. These faults will damage the steel wire rope and the tank path and affect normal production. Cage, skip) fell into the well and other vicious accidents. [0003] In order to detect the failure of the mine hoist stuck in the tank and the loose rope, there is a method to install the load sensor on the hoisting container, and send the hoisting load signal to the well through the wire rope. This method is easily affected by interference, the accuracy is no...
