Description

Technical Field

[0001] This utility model relates to the field of hoist technology, specifically to a hoist sprocket tensioning structure. Background Technology

[0002] The bucket elevator completes the transportation process by driving the flexible steel wire rope and the transported goods up and down through power machinery. The steel wire rope is an indispensable and important part of the lifting machinery. The bucket scoops up the material from the storage below, lifts it to the top with the conveyor belt or chain, and flips it down after passing over the top wheel. The bucket elevator pours the material into the receiving trough. The drive belt of the belt-driven bucket elevator is generally made of rubber belt and is installed on the lower or upper drive drum and the upper and lower idler drums.

[0003] In existing technologies, the lifting chain may become loose due to various reasons, making it extremely inconvenient to adjust the tension of the lifting chain and impossible to quickly replace the tensioning wheel as needed. To address this, we propose a lifting machine sprocket tensioning structure. Utility Model Content
