1. Mine winch The main reason of drum abnormal noise
(1) the bolt of drum shell is loose.
(2) the clearance between cylinder housing and support wheel (flange) is too large.
(3) the drum shell is broken.
(4) open the welding shell for welding.
(5) the fixing screws of the swimming roller and the bushing are loose, resulting in the relative sliding between the swimming roller and the bushing.
(6) excessive wear of clearance between bushing and spindle.
(7) worm gear clutch is loose.
According to the inspection, determine the processing method. For loosening nuts, etc. They can be tightened when the shift stops; if the sound is not serious, the winch load can be appropriately reduced, observed and observed, and maintained until the specified shutdown for maintenance. If the sound is serious, stop repairing immediately. Or replace it to prevent the accident from spreading.
(2) the wire rope of winch drum is dangerous, and the causes and treatment methods are not neat
1. The wire rope on the drum of hoisting winch is not dangerous.
(1) accelerate the wear of wire rope. When the wire rope is ground on the drum, the wire rope will be seriously damaged and broken when it is used. a wire rope.
(2) slide the wire rope out of the drum. The irregular arrangement of wire rope will inevitably lead to the accumulation and damage of wire rope shield. When the pile height is higher than the edge height of the drum, the wire rope is easy to slide out of the drum, the light rope breaks and the heavy rope breaks.
2. The main reasons for the irregularity of wire rope arrangement on hoist drum
(1) improper hoisting rope arrangement, i.e. the hoisting rope does not meet the requirements.
(2) the winch balance wheel (guide wheel) is short of oil, and the steel wire rope is wound on the drum and cannot slide left and right.
(3) the rope guiding device of winch is invalid or has been removed.
(4) improper operation and loose winding.
According to different conditions, symptomatic treatment. If the installation quality and rope removal device fail, it shall be reported in time and asked the dispatcher to deal with it. In case of improper operation or maintenance, handle and maintain it carefully according to regulations. Special attention should be paid to removing obstacles to prevent weight reduction of inclined roadway winch. When the object is tight, the wire rope is loose.
