Abstract

The invention relates to a mining conveyer carrier roller fault monitoring, positioning and warning device. By laying sensing optical fibers on two sides of a carrier roller, vibration information of a conveying belt passing through the carrier roller is captured and is transmitted to a signal analysis and processing module, and a timely alarm is given when a fault of the carrier roller is detected. A site warning device is arranged in a coal mine transportation site, and a PC monitoring terminal is arranged in a remote monitoring chamber. The mining conveyer carrier roller fault monitoring, positioning and warning device can achieve mining conveyer carrier roller fault monitoring, positioning and warning in a severe environment of coal mine production and has a higher application value.

Description

Technical field [0001] The invention relates to a mine conveyor roller failure monitoring and positioning and alarm device, in particular to a device for monitoring, fault location and timely alarming of the mine conveyor roller through distributed optical fiber vibration sensing technology . Background technique [0002] Belt conveyors have the advantages of large transportation capacity, long transportation distances, and low energy consumption. They are widely used in coal, mines, ports, electric power, metallurgy, and chemical industries. The roller is an important part of the belt conveyor that is used extensively. It is a long revolving component that supports the conveyor belt. Its function is to support the belt and the load, reduce the running resistance of the belt, and ensure the smooth operation of the belt. The operating conditions of the rollers play a key role in the life of the conveyor belt and conveyor. The rollers in large-scale mining conveyors are of variou...
