Description

Technical Field

[0002] The elevator completes the transportation process by using a power machine to drag the flexible wire rope and the transported goods up and down. The wire rope is an indispensable and important part of the lifting machinery. The bucket scoops up the material from the storage below, and it is lifted to the top with the conveyor belt or chain. After passing the top wheel, it turns downward. The bucket elevator pours the material into the receiving trough. The drive belt of the belt-driven bucket elevator is generally a rubber belt, which is installed on the lower or upper drive roller and the upper and lower redirecting rollers. After the elevator has been used for a period of time, its own gravity, tensile stress or frictional force may easily cause the chain to deform and lengthen, which may easily cause the sprocket and chain to become uncoupled. Therefore, the chain tensioning needs to be adjusted. The existing elevator sprocket tensioning structure includes a mounting plate, a sprocket, a chain, a fixed plate, a tensioning assembly, an L-shaped plate, a screw, a knob, a threaded block, a connecting rod, a transmission assembly, a movable plate, a rotating rod, a tensioning wheel, a limit assembly, a T-slot, a T-block, a disassembly assembly, a U-shaped frame, a cross bar, a push plate, a counterweight, and a mounting seat. This elevator sprocket tensioning structure supports the tensioning wheel through a support rod during the tensioning process, which may easily cause the chain to fall off during use and affect the tensioning effect, and may also cause the tensioning wheel to be displaced after the device vibrates during use.
