Conveyor belt maintenance mainly includes the following aspects:
Daily inspection and maintenance:
Lubrication: Ensure that the lubricant is filled before starting the machine, and check and replenish the lubricant regularly during operation.
Cleaning: After production, clean the conveyor belt surface with clean water, remove broken bottle residues and lubricating fluid, and wipe off water droplets on the detection components and electrical parts.
Component inspection: Regularly check the guide fence spacing, bearing parts and grease, and change the oil of the transmission reducer at the specified time.
Rollers and rollers: Frequently check the rotation of each roller and roller, and replace them immediately if damage is found.
Temperature monitoring: Monitor the temperature of the reducer, hydraulic coupling, motor and each roller to ensure that it is within the normal range and there is no abnormal sound.
Leakage inspection: Check whether the reducer and hydraulic coupling have leakage and whether the oil level is normal.
Tensioning device: Ensure that the belt tensioning device is in good condition, without falling off the track, the tensioning winch can move freely on the track, and the belt tension can be adjusted at any time.
Sweeper: Ensure that the sweepers in each part can work normally, and the distance between the sweeper and the belt is not more than 3 mm.
Special situation handling:
Material control: When conditions permit, try to reduce the distance between the coal feeder and the conveyor belt to reduce the impact and wear of the material on the conveyor belt.
Foreign matter handling: Strictly control the entry of water coal, large pieces of materials and ironware into the conveyor belt. If large pieces of materials and ironware are found on the conveyor belt, stop the machine in time for processing.
Edge wear treatment: Repair the edge wear, longitudinal tear in the middle and debonding parts of the conveyor belt in time.
Joint treatment: If the conveyor belt joint is severely deformed or cracked, and the metal clip is deformed or damaged, it is necessary to reconnect, reshape or replace the metal clip.
Self-aligning rollers: Add necessary self-aligning rollers, anti-bias protection, belt breakage and slip protection to ensure the normal operation of the conveyor belt.
Safe operation and maintenance:
Operating procedures: Operate the belt conveyor strictly according to the operating procedures. Operators should hold an operating certificate and strictly implement the safe operating procedures.
Emergency stop device: When the conveyor length exceeds 100 meters, an emergency stop device should be installed along the line.
Intelligent operation and maintenance: With the development of technology, intelligent operation and maintenance can provide coal mining enterprises with belt conveyor fault prediction, maintenance and repair suggestions, equipment usage data statistics, and reduce fault downtime.
