Coal mining scraper conveyor are commonly used transportation equipment in coal mine production and are widely used in coal mining face, transportation lane, connecting lane and ground transportation. So what are the preventive measures for the maintenance of the coal mining scraper conveyor?
Timely and reasonable maintenance can extend the life of the coal mining scraper conveyor, and ensure its safe operation. The most troublesome fault of the conveying system is the chain drop and jamming of the bottom groove. Not only will the scraper chain be blocked by the bottom groove and cannot run, it may even cause the motor to be overloaded and burn out or the tail will be pulled over and cause personal accidents. When processing, it is necessary to dismantle many middle grooves, which will affect the production time for a long time. In order for the coal mining scraper conveyor, to operate normally and give full play to its best performance, maintenance must be carried out in accordance with relevant requirements and the poor working conditions of various components must be adjusted.
(1) Class inspection content
Scraper chain, connecting link, coupler, head shaft and other moving parts, replace the curved scraper; Whether the sprocket shaft group is operating normally, whether there is oil leakage, whether the oil temperature is ≤90℃, whether the auxiliary fuel tank oil level meets the standard; various electrical appliances Whether the equipment is damaged, whether the motor has abnormal sound and vibration, and the temperature rise is ≤105K; whether the reducer of the coal mining scraper conveyor is leaking, whether there is abnormal sound and vibration, and the oil temperature is ≤90℃; whether the tail of the coal mining scraper conveyor is present Too much back coal, if necessary, find out the cause; Whether the middle groove is raised, whether the fixing pin is withdrawn, whether the fixed parts such as the cable groove are damaged; Adjust the matching position of the transfer machine and the coal mining scraper conveyor to achieve the best work Status: Whether the working surface is straight, whether the switch has heat or abnormal noise.
(2) Daily inspection content
Repeat shift inspection content; Whether the tension of the scraper chain of the coal mining scraper conveyor is appropriate and whether the tension of the two chains is the same; Whether the sprocket is damaged; Whether the derailleur is normal, and there should be no skew or chain jam; Reducer, coupling Whether the amount of oil and liquid meets the requirements, whether there is oil leakage or leakage; whether the bolts of the reducer, sprocket, blind shaft, coal baffle, shovel plate and scraper are loose; replace worn and damaged chain rings, connecting chain rings and Scraper.
(3) Weekly inspection content
Repeat the daily inspection content; Whether the head frame and tail frame of the coal mining scraper conveyor are damaged or deformed; Whether the fixing bolts of the reducer and the connecting bolts at both ends of the coupling protection cover are tight; The oil quality of the reducer of the coal mining scraper conveyor Whether it is good, whether the amount of oil is appropriate, the lubrication status of the bearings, gears, and the meshing of each gear; the insulation of the motor, the switch contacts and the explosion-proof surface; the wear of the derailleur, the pressure chain block and the coal shovel and the connection bolts reliability.
(4) Seasonal inspection content
Repeat the weekly inspection content; repair and replace the coupling, fluid coupling, sprocket, adjusting groove, etc.; check the coal mining scraper conveyor motor and reducer more comprehensively.
