Description

Intelligent lubricating system for coal mine belt conveyor and intelligent grease injection method
Technical Field
The invention relates to an intelligent lubrication system and an intelligent grease injection method for a coal mine belt conveyor.
Background
The belt conveyor is an underground important electromechanical device, all coal mined from the production surface is conveyed to the coal bunker through the belt conveyor, and then the coal bunker is lifted, so that the belt conveyor is an important device for ensuring the yield of the coal mine, and the maintenance and the preservation of the belt conveyor are very critical. The center of gravity of maintenance work is the application of lubrication technology, and in order to ensure the best performance of the bearing, a proper lubrication system is needed to be used, and proper lubrication points and proper lubrication time are used for lubrication by proper amounts of proper lubricants. Therefore, intelligent lubrication of the underground coal mine belt conveyor is necessary.
The coal mine belt conveyor is subjected to three stages of manual lubrication, automatic lubrication and intelligent lubrication. 1) The labor intensity of manual lubrication workers is high, and the lubrication period and the lubrication quality are difficult to ensure. Sometimes forget to lubricate the roller bearing due to negligence, the bearing heats up and is damaged, and the conveyor stops running. 2) The automatic lubrication is realized by the lubrication pump, the lubricant is timely, quantitatively and accurately supplied to each lubrication point of the belt conveyor through the distributor, and oil quantity and alarm monitoring can be carried out on each lubrication point. The friction and the abrasion are reduced to the maximum extent, and meanwhile, the danger caused by manual lubrication is eliminated. Centralized lubrication includes single-wire lubrication systems, two-wire lubrication systems. 3) The intelligent lubrication is realized by taking the set working condition as a target, taking the lubrication effect as an optimal target, taking the high-precision sensing signal as a support, taking the intelligent optimal control strategy and the grease distribution algorithm as means, and combining the means of network real-time monitoring, mobile phone App and the like. The intelligent lubrication system has a complete self-checking means, ensures reliability and basically realizes operation maintenance-free. After the guidance opinion about accelerating the intelligent development of the coal mine comes out, the current development of the intelligent construction of the coal mine is in the aspect of electromechanical equipment management, the real-time accurate sensing of the running state of the equipment is the premise of intelligent remote/automatic control, and the intelligent and unmanned basis for the production of the coal mine is realized. The existing monitoring and monitoring system for the mining machinery equipment stays on the visual display of sensing data and the level of simple threshold analysis (exceeding of signal values and overrun), the maintenance of the equipment mainly adopts a spot inspection mode, and the maintenance of the equipment adopts a periodic and post-treatment mode. Thus, intelligent lubrication of belt conveyors is thus urgent.
The existing intelligent lubrication adopts a controllable timing and quantitative method, has outstanding advantages compared with manual lubrication, but the biggest problem belongs to an open loop control mode, and inevitably has some unavoidable problems:
1. lubrication is possible when lubrication is not needed, so that the waste of lubricating oil is caused; lubrication is also provided "not too tight" when "strong" lubrication is required.
2. Lubrication adjustment is not fed back with lubrication effect, and a lubrication effect test sensor, such as a vibration sensor, is absent.
3. The degree of automation is not obvious, and the method generally belongs to on-site automatic control, lacks a networking communication function and lacks an APP collection function.
4. Lack of grease pressure sensors, flow sensors, and occlusion alarm sensors.
