Monitoring and service life managing system for belt conveyor

Abstract

The invention discloses a monitoring and service life managing system for a belt conveyor. A master controller positioned on the machine head of the belt conveyor communicates with a plurality of input and output controllers which are positioned on a plurality of joints along the belt conveyor, the input and output controllers acquire fault signals of off-tracking, over-temperature, smoke, coal piling, tearing and slipping of the belt conveyor as well as temperature signals of a motor, a gearbox and a roller, an adhesive tape operation speed signal, a motor current signal, and vibration signals of the motor and the gearbox, and the master controller analyzes, computes and processes acquired information through a human-computer interface based on VB, so that comprehensive monitoring, in an operation process, of the belt conveyor as well as service life management on the motor, the gearbox, the roller and a carrier roller part is realized. According to the monitoring and service life managing system disclosed by the invention, the operation state of the belt conveyor is monitored in real time, corresponding control signals can be output according to monitored information, and management is carried out on service life of the motor, service life of the gearbox, service life of the roller and service life of the carrier roller, so that safety, stability and continuity of operation of the belt conveyor are improved.

Description

technical field [0001] The invention relates to a coal mine belt conveyor monitoring system, in particular to a system which utilizes a main controller to communicate with a plurality of input and output controllers to realize comprehensive monitoring and life management of the belt conveyor running process. Background technique [0002] With the continuous expansion of the scale of coal mines and the continuous improvement of the automation of coal mine production equipment, the belt conveyor is also developing towards the trend of large capacity, high belt speed and long distance. The transportation tasks it undertakes are becoming more and more important, and its work is reliable. It directly affects the continuity, safety and economic benefits of coal production. [0003] At present, the management of belt conveyors in most mines in China is limited to the protection of common faults such as deviation, tearing, slipping, over-temperature, smoke, coal piles, etc. Life ma...

Problems solved by technology

[0003] At present, the management of belt conveyors in most mines in China is limited to the protection of common faults such as deviation, tearing, slipping, over-temperature, smoke, coal piles, etc. Life management of motors, gearboxes, pulleys, and idlers

Existing coal mines use more belt conveyor monitoring systems, such as the KJ50 PROMOS monitoring system produced by the German Baker Group, the KHP157 belt conveyor protection device produced by Changzhou Lianli Automation Technology Co., Ltd., etc., and there are currently disclosed technologies , such as the invention patent of "a mine explosion-proof and intrinsically safe belt conveyor protection device" and the utility model patent of "a mine belt conveyor intelligent monitoring device", the main problem is: only It can realize the monitoring of the working condition information of the belt conveyor, such as the working current, ambient temperature, and running speed, and the protection of faults such as deviation, tearing, coal pile, over-temperature, and smoke. The requirements for life management of motors, gearboxes, rollers, and rollers of the conveyor belt, and fault and maintenance alarms can only be issued after a fault occurs. condition maintenance
