Device for monitoring states and diagnosing faults of coal mine underground working surface conveyer

Abstract

The invention discloses a device for monitoring conditions and diagnosing faults of a coal mine underground working surface conveyer, which consists of a state monitoring and fault diagnosis central station and a substation, uses PLC for control, adopts a modularization design, and supports multi-bus data transmission. The device realizes the real-time monitoring and display of the following parameters: the bearing temperature, the oil temperature and the oil level of a speed reducer matched with the devices of a working surface conveyer namely a slat conveyer, a reversed loader, a crusher and the like; the stator temperature and the rotor bearing temperature of a motor; and the flow and the pressure of cooling water, and the distance between a coal mining machine and the slat conveyer, and the like. The device diagnoses the running states of the conveyer and makes an early warning or an alarm. The device can meet different requirements underground a coal mine, has the advantages of simple structure, convenient maintenance and expansion, convenient and fast network deployment and the like, reaches the aims of performing long-distance and on-site real-time monitoring and fault diagnosis on the working surface conveyer, and realizes the production target of safe, stable and reliable operations in a coal mine.

Description

technical field [0001] The invention relates to a state monitoring and fault diagnosis device for conveying equipment in underground coal mines, in particular to a state monitoring and fault diagnosing device for conveying equipment in underground working faces of coal mines. Background technique [0002] Comprehensive mechanization is an important symbol of the modernization of coal mine mining technology, and its working face conveying equipment refers to conveying equipment composed of scraper conveyor, crusher, reloader and belt conveyor. As the only underground coal conveying equipment, the working face conveying equipment is one of the keys to coal mining for its safe and reliable operation. The necessity of monitoring and diagnosing the operating parameters of these equipment is self-evident. On the other hand, in order to achieve the primary goal of "unmanned mining" working face, it is necessary to accurately obtain sufficient operating parameters of the working fac...
