Abstract
A power transmission system of a scraper conveyor comprises a head power portion and a tail power portion. The head power portion comprises a parallel transmission mechanism parallel to a scraper chain and a vertical transmission mechanism perpendicular to the scraper chain, and the head power portion and the tail power portion jointly drive sprocket shafts to drive chains and scrapers to rotate circularly so as to realize corresponding variable-speed large-torque movement. The power transmission system is reasonable in configuration of head power portion and the tail power portion, high in coal mining capacity and applicable to working conditions of extra-heavy-duty scraper conveyors, and has a conveying capacity up to above 3700 tons per hour. Variable-frequency motors are used for powering and used with torque-limited friction clutches to transmit power to planetary gear reducers, and hydraulic chain tensioners are further provided, so that slow starting of the scraper conveyor is realized, impact force applied to related parts of equipment and generated when the motors are started is lessened, reliability of key parts such as the reducers, the chains and the sprocket shafts is guaranteed, and the service life of the equipment is prolonged. Moreover, the power transmission system of the scraper conveyor has the advantages of high efficiency, energy conservation and consumption reduction.
