Description

Technical Field

[0001] The utility model relates to the technical field of mine belt roller replacement equipment, in particular to an auxiliary device for replacing mine belt conveyor rollers. Background Art

[0002] Belts are the most important transportation equipment in the industrial and mining industries and are widely used. Due to the development of coal mining technology, the design length of underground belt conveyors is relatively long, and the number of rollers used is large. The rollers need to be replaced regularly. When actually repairing and replacing rollers, the larger the equipment, the heavier the transported belt, and the more difficult it is to replace the supporting rollers in the lane. The replacement of rollers is done by manually disassembling them and removing them directly from the frame of the belt conveyor. Since the replacement is more laborious, most of them use auxiliary devices to replace the rollers of underground belt conveyors to assist in completing the roller replacement operation.

[0003] However, the existing auxiliary device for replacing the rollers of the underground belt conveyor is not convenient to move due to the large number of rollers to be replaced, and the main body with the mobile device needs to use an external object to lock the universal wheel to achieve the fixation of the auxiliary device. Since the contact area between the universal wheel and the ground is small, when the auxiliary device supports the roller, the universal wheel is easily damaged by the force, so that the auxiliary device cannot be stably supported, and the use effect is poor. For this reason, we propose an auxiliary device for replacing the rollers of the underground belt conveyor. Utility Model Content
