Abstract

The invention discloses a hydraulic motor chain tightening device, belonging to coal mine underground machinery, and solving the technical problems of existing scraper conveyor chain tightening device such as poor chain tightening effect, low working efficiency and easy occurrence of accident in chain tightening work process. The hydraulic motor chain tightening device comprises a swivel stand (15) hinged with a swivel stand fitting seat (16), a hydraulic motor is fixedly arranged on the swivel stand (15), the output shaft of the hydraulic motor is mechanically connected with the gear shaft of an input gear component in the swivel stand (15), the input gear component is meshed with a chain tightening gear (9) arranged on a mechanical connecting shaft (8) between a speed reducer and a driving motor via an idle gear. The invention has the advantages of low speed, large torque, high stability, safety and reliability, convenient operation, capability in tightening the chain to the proper degree once and for all.

Description

technical field [0001] The invention relates to a coal mine underground machine, in particular to a chain tightening device of a scraper conveyor on the coal mine underground working face. Background technique [0002] At present, the chain tightening device used by the scraper conveyor in the underground working face is a brake disc chain tightening method, which adopts a manual clamping mechanism, and the pretightening force of the chain is proportional to the braking torque. The chain tightening process requires the motor to be reversed to tighten the chain to a certain extent, and the motor is powered off instantly, and at the same time, emergency manual braking is used to achieve the purpose of tightening the chain. This manual chain tightening is affected by the proficiency of the workers and the wear of the brake belt on the chain tensioner. Due to the degree of restriction, it is difficult to tighten to a suitable elastic requirement at one time, and the operation mu...
