The invention relates to a winding mechanism, and particularly discloses a winding hydraulic control system. The winding hydraulic control system comprises a working oil way, an oil supplementing oilway, a flushing control unit and a variable pump control oil way; a hydraulic motor and a variable pump are arranged in the working oil way; an oil supplementing pump is arranged in the oil supplementing oil way, and the oil supplementing oil way is connected with the first working oil way and the second working oil way so that oil can be supplemented to one of the first working oil way and the second working oil way with low oil pressure; the flushing control unit comprises a flushing valve, a controller and a rotating speed sensor, a first flushing oil port of the flushing valve is connectedwith the first working oil way, the first flushing oil port is connected with an oil drainage oil way, and a third flushing oil port is connected with the second working oil way; the controller can receive signals of the rotating speed sensor and control connection and disconnection between the first working oil way and the oil drainage oil way through the flushing valve; the variable pump control oil way is connected with the variable pump so as to change the displacement of the variable pump. In addition, the invention further relates to a winding engine. According to the winding hydrauliccontrol system, the micro-motion stability of the winding can be improved.
