Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to a quick belt changing device for a main inclined shaft belt conveyor. Background Art

[0002] The main inclined shaft belt conveyor belt changing equipment is a special equipment used to replace the conveyor belt of the belt conveyor. During the main inclined shaft belt conveyor belt changing process, it can be used to pull the old belt and the new belt, mainly through the drum winding wire rope to achieve the output of traction force, pull the old belt off the belt conveyor, or pull the new belt into place along the path of the belt conveyor.

[0003] When the existing main inclined shaft belt conveyor's quick belt changing device is in use, the old belt may be accidentally offset during the conveying process due to external interference or gravity, requiring a large amount of position adjustment work, increasing the workload of the operator and aggravating the wear of the belt edge. Moreover, when the belt suddenly shakes while being wound, its edge may be rolled into the gap of the winding frame, causing folding, twisting, etc., affecting the replacement efficiency of the entire belt. In addition, after the winding frame is completed, it needs to be shut down and take a long time to disassemble and replace the winding frame. For this, multiple belt replacement tasks must be completed, greatly increasing the duration of the belt changing process. Summary of the invention
