Method for detecting operation troubles of mine hoist

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.
