A mine belt conveyor fault monitoring and early warning system and method

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 mining equipment fault monitoring, and particularly relates to a mine belt conveyor fault monitoring and early warning system and method. Background technique [0002] Belt conveyor, also known as belt conveyor or belt conveyor, is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of frame, conveyor belt, roller, roller, tensioning device, transmission device, etc. Both the head and tail of the conveyor are equipped with rollers, and the rollers installed at the head and tail include a driving roller and a steering roller (also called a guide roller) located on one side of the driving roller. Coal mine belt conveyors (also called mine belt conveyors or mine belt conveyors) are belt conveyors installed in underground tunnels of coal mines. As a horizontal or inclined transportation tool, they have been widely used in various coal mines. At present, belt conveyors...

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
