Hydraulic drum winch control mechanism

The utility model relates to a hydraulic roller winch control mechanism, which belongs to the roller winch technical field. The hydraulic roller winch control mechanism is proposed that a hydraulic dynamic source can drive a hydraulic motor through a control valve by a pipeline, and the hydraulic motor drives a roller; and the hydraulic roller winch control mechanism is characterized in that: a main circuit forms the hydraulic dynamic source by an electric proportional variable pump and a hydraulic control variable pump through the parallel connection; the hydraulic dynamic source drives the hydraulic motor; an oil control hole of the electric proportional variable pump is connected with an oil control hole of the hydraulic control variable pump through a unidirectional valve; an oil control channel is connected into a hydraulic guiding control valve and the unidirectional valve so as to form a control structure which integrates the hydraulic control with the electric control. After adopting the local hydraulic control and the fixed remote control as well as movable remote control, through integrating the electric control with the hydraulic control, the hydraulic roller winch control mechanism enriches the control methods of the work progress, and greatly improves the construction efficiency.
