Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of dismounting equipment, and specifically belongs to the belt conveyor sealing cover dismounting equipment. BACKGROUND

[0002] The conveying belt of Changshanyan sludge treatment center is an upper and lower fully-sealed belt conveyor. Due to the particularity of the conveyed material, a large amount of semi-wet sludge is often accumulated in the sealing material receiving cover and needs to be cleaned. Before cleaning, the sealing material receiving cover needs to be dismounted from the belt conveyor rack. Due to the large amount of semi-wet sludge accumulated in the lower sealing material receiving cover and its own weight, a large amount of manpower is required to dismount it, and there is a certain risk. When the conveying belt is replaced with upper and lower supporting rollers, manpower is also required to dismount the upper and lower sealing covers. Since the upper and lower sealing covers are arranged along the belt conveyor at 1.4 m per section, the number is large, and each dismounting operation consumes a lot of time and manpower, and is difficult to complete, requiring the cooperation of multiple people.
