Power and free overhead conveyer for logistic orbital transfer weight sorting transportation

The invention discloses a power and free overhead conveyer for logistic orbital transfer weight sorting transportation. The conveyer comprises a high-speed chain rack, an overhead conveyer, a low-speed chain rack and a control system, wherein the high-speed chain rack is internally provided with a high-speed chain traction orbit below which a chain wheel device is arranged; a high-speed chain bearing orbit is arranged below the chain wheel device; the high-speed chain traction orbit is provided with a driving wheel on which a traction rod is arranged; the lower end of the traction rod is connected with a guide block arranged on the chain wheel device; two ends of the chain wheel device are provided with chain wheel driving systems; and each chain wheel driving system is internally provided with a load feedback jacking system. The power and free overhead conveyer has the advantages that a transportation trolley of the conveyer is of a lifting claw structure, the kinetic energy of the trolley is converted into
