According to the four-quadrant composite recycling and regenerating integrated winch driving system, the advantages of electric driving and hydraulic driving are integrated, cooperative active control over the rotating speed and the torque of the motor and passive control over the energy accumulator-variable hydraulic pump motor are utilized, and the stability of the system is improved. And integration of electric power generation-variable hydraulic pump motor multi-quadrant coordination control and energy combined type recovery and regeneration is realized. The high energy density of the electric energy storage unit and the good control characteristic of the motor are exerted, and a solution is provided for the problems of secondary gliding of the load and limited energy recovery of the energy accumulator; the closed type hydraulic system which the energy accumulator-variable hydraulic pump motor belongs to is used for obtaining high power density and near-zero rotating speed large torque output, and the problems that an electric drive winch is high in energy consumption, and part of energy is consumed in a balance valve and a multi-way valve are solved. According to the pure electric winch driving system, noise and pollution of an engine to the environment are reduced, the working efficiency of the whole machine is greatly improved, the requirements of energy conservation and emission reduction in China are met, intelligent control is conveniently achieved, and the system adapts to age development.
