Fault monitoring and early warning system and method for belt conveyor of mine

Abstract

The invention discloses a fault monitoring and early warning system and method for a belt conveyor of a mine. The fault monitoring and early warning system comprises an upper monitor, a conveyor working condition detecting device, a data acquiring device, an early warning prompting device and a timing circuit, wherein the conveyor working condition detecting device detects working conditions of a monitored belt conveyor in real time; the data acquiring device is connected with the conveyor working condition detecting device; the early warning prompting device is controlled by the upper monitor; and the timing circuit is connected with the upper monitor. The fault monitoring and early warning method comprises the following steps: 1, detecting the working conditions of the conveyor and synchronously uploading detection information; and 2, analyzing and processing of information of the working conditions of the conveyor: respectively analyzing and processing the information, which is acquired by the data acquiring device at various sampling times, of the working conditions of the conveyor by using the upper monitor in sequence according to the sampling times, and diagnosing faults of the monitored belt conveyor according to analyzed and processed results. The fault monitoring and early warning system is reasonable in design, easy and convenient to use and operate and good in using effect, can timely and accurately monitor faults of the belt conveyor, and can early warn in time.

Description

technical field [0001] The invention belongs to the technical field of mine equipment failure monitoring, in particular to a mine belt conveyor failure monitoring and early warning system and method. Background technique [0002] Belt conveyor, also known as belt conveyor or belt conveyor, is a machine that is driven by friction to transport materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. Rollers are installed at the head and tail of the conveyor, and the rollers installed at the head and tail include driving rollers and steering rollers (also called guide rollers) on one side of the driving rollers. Coal mine belt conveyor (also known as mine belt conveyor or mine belt conveyor) is a belt conveyor installed in the underground roadway of coal mine. As a tool for horizontal or inclined transportation, it has been widely used in various coal mines. At present, the belt conveyor...

AI Technical Summary

Problems solved by technology

[0003] If the belt conveyor is used improperly or not repaired and maintained in time during operation, it is prone to failure, which will not only destroy the equipment, but sometimes cause personal accidents

At present, most of the failures of mine belt conveyors are dealt with afterwards. Specifically, after the failure occurs, the maintenance personnel will check the causes of the failure one by one, which is labor-intensive and time-consuming, and is mainly based on the experience of the maintenance personnel. Judgment, unable to find out the cause of the failure in a timely, fast and accurate manner and take corresponding measures
