Roller failure monitoring system of belt conveyer

Abstract

The invention relates to a failure monitoring system of a roller of a belt conveyer, which mainly comprises a sensor, a mechanical device for moving the sensor, a communication substation and the like, wherein the sensor comprises a power module, a data acquisition module, a controller module and a communication module; a sensitive element of the data acquisition module is a unidirectional type electret microphone; the mechanical device comprises a synchronous belt, synchronous belt wheels on both ends of the synchronous belt, a supporting wheel in the middle of the synchronous belt and a stretching wheel; the sensor fixed on the synchronous belt is moved to the position near to any roller position by utilizing the operation of the mechanical device; the sensor collects sound signals and the like generated by the rotation of rollers and carries out the data processing and the extraction of failure signals; and the failure diagnosis result is sent to the communication substation and transmitted to a monitoring room through an optical network. The system is especially suitable for automatic routing inspection of the belt conveyer under a coal mine, discovers the abnormal working condition of the roller in time and guarantees the normal production of the coal mine.

Description

technical field [0001] The invention relates to a belt conveyor roller failure monitoring technology, in particular to a coal mine underground belt conveyor roller failure monitoring technology. Background technique [0002] At present, belt conveyors are widely used in the transportation of underground coal mines in my country and are the main equipment for underground coal mine transportation. The idler roller is one of the most important components that determine the use effect of the belt conveyor (especially the service life of the belt). However, during the operation of the idler roller, there will be various abnormal conditions, such as idler bearing failure, poor operation of the roller, dust adhered to the surface of the roller, loose bolts of the idler frame, etc., which may cause the conveyor belt to deviate, If it is heavy, it will directly cause the conveyor to fail to work. At this stage, the automation of belt conveyor idler fault detection is relatively low...

Problems solved by technology

However, during the operation of the idler roller, there will be various abnormal conditions, such as idler bearing failure, poor operation of the roller, dust adhered to the surface of the roller, loose bolts of the idler frame, etc., which may cause the conveyor belt to deviate, If it is heavy, it will directly cause the conveyor to fail to work

At present, domestic belt conveyor idler fault detection has a low degree of automation, mainly relying on regular manual inspections by coal mine staff, and judging whether there is a fault by manually listening to the sound of the idler roller during operation

Due to the harsh underground working environment and the large number of conveyor rollers, the labor intensity of regular manual inspection is very high, and sometimes the abnormal working conditions of the rollers cannot be found in time, which will directly affect the normal production of the coal mine
