Intelligent lubricating system for coal mine belt conveyor and intelligent grease injection method

Abstract

The invention relates to an intelligent lubricating system for a coal mine belt conveyor and an intelligent grease injection method. A PLC control box is separately connected with a grease supplementing pump and a grease injection pump. The PLC control box is connected with a monitoring system upper computer, and the monitoring system upper computer is networked with an underground monitoring system. A temperature sensor, a vibration sensor and a blockage sensor form a group of sensor parts, and the temperature sensors and the vibration sensors are mounted at the machine head or the machine tail of the belt conveyor. An intelligent boxes are in one-to-one correspondence with oil path controllers, and each intelligent box is provided with a group of sensor parts. The intelligent grease injection mode of the intelligent boxes comprises a strong grease injection area, a weak grease injection area and a stop area. According to the intelligent lubricating system for the coal mine belt conveyor and the intelligent grease injection method, the intelligent lubricating design is adopted, the fault rate of a belt conveyor bearing is greatly reduced, the temperature of the bearing is controlled within a certain range, vibration and noise are obviously reduced, and the expected effect is achieved; and due to intelligent lubrication, the breakdown time of equipment is greatly shortened, the consumption of spare part materials is greatly reduced, meanwhile, the labor intensity of workers is reduced, and remarkable economic benefits and social benefits are obtained.

Description

technical field [0001] The invention relates to an intelligent lubricating system and an intelligent grease injection method for belt conveyors in coal mines. Background technique [0002] The belt conveyor is an important mechanical and electrical equipment in the mine. The coal mined from all production surfaces is transported to the coal bunker through the belt conveyor, and then the coal bunker is lifted into the well. It is an important equipment to ensure the output of the coal mine, so its maintenance and maintenance are very important. . The focus of maintenance work is the application of lubrication technology. In order to ensure the best performance of the bearing, the correct lubrication system must be used, and the correct amount of suitable lubricant should be used for lubrication at the appropriate lubrication point and the correct lubrication time. For this reason, the intelligent lubrication of belt conveyors in coal mines is very necessary. [0003] The co...

Problems solved by technology

[0004] The existing intelligent lubrication adopts controllable timing and quantitative methods, which have outstanding advantages compared with manual lubrication, but its biggest problem is the open-loop control method, and there must be some unavoidable problems:

[0005] 1. Lubrication may still be carried out when no lubrication is required, resulting in a waste of lubricating oil; when "strong" lubrication is required, lubrication is still provided "unhurriedly"

[0006] 2. There is no feedback lubrication adjustment based on the lubrication effect, and there is a lack of lubrication effect test sensors, such as vibration sensors

[0007] 3. The degree of automation is not obvious, generally belongs to local automatic control, lacks networking communication function, and lacks collection APP function

[0008] 4. Lack of grease pressure sensor, flow sensor, blockage alarm sensor
