Description

Technical Field

[0001] The utility model belongs to the technical field of bucket elevators, and in particular relates to a belt tightening and docking tool. Background Art

[0002] Belt bucket elevator is widely used in metallurgy, chemical industry, coal, grain and other industries. It is the preferred equipment for vertically lifting powder or small granular materials. The vertical lifting height can reach 30 meters. Its working principle is that the belt with steel buckets installed at a certain interval is wound around the head wheel and the tail wheel. The head wheel is driven by the motor to rotate, driving the belt to run and the tail wheel to rotate at the same time. The bucket on the belt lifts the lower material to the upper part and throws it out, thereby achieving the lifting of the material.

[0003] At present, the belt joint butt joint method used in belts is to overlap two belt ends and fix steel plates on both sides by bolts. It is necessary to use a fall chain to hook the steel plates fixed on the two belt joints to stretch them, and then increase the overlapping part of the belt joints through the steel plates to make it more stable during use. However, due to the weight of the belt and the surface tension after stretching, there is a gap between the two belt joints, which makes it very inconvenient to clamp the steel plates during the fixing operation. Therefore, a belt tensioning butt joint tool that can butt and tighten the belts is proposed. Utility Model Content
