A hydraulic winch control system with a hydraulic motor oil supplementing function comprises a hydraulic motor for driving a hydraulic winch to rotate, a brake connected with the hydraulic motor, a winch valve group for controlling the hydraulic motor to rotate, and a control valve group connected with the winch valve group. The load-sensitive pump is used for conveying hydraulic oil from an oil tank to the control valve group; the oil supplementing path is used for connecting the control valve group with the hydraulic motor; hydraulic oil is pumped out of the oil tank by the load-sensitive pump, sequentially passes through the control valve group and the winch valve group and then enters the hydraulic motor to drive the hydraulic motor to rotate, so that the lifting of the hydraulic winch is realized; and the oil supplementing path is used for supplementing hydraulic oil in the hydraulic motor and maintaining the stable working pressure of the hydraulic motor. The pressure of the motor in the standby state of the system is maintained by arranging the oil supplementing path, and the unstable condition caused by oil shortage of the motor is avoided.

    一种具有液压马达补油功能的液压绞车控制系统包括驱动液压绞车转动的液压马达,与所述液压马达连接的制动器,控制所述液压马达转动的绞车阀组,与所述绞车阀组连接的控制阀组,将液压油从油箱输送至所述控制阀组的负载敏感泵,以及连接所述控制阀组和所述液压马达的补油路;所述负载敏感泵将液压油从所述油箱中抽出依次经过所述控制阀组和所述绞车阀组后进入所述液压马达,驱动所述液压马达转动,实现液压绞车的升降;所述补油路实现对所述液压马达内液压油的补充,维持所述液压马达的稳定工作压力。本发明通过设置补油路维持马达在系统待机状态下的压力,避免马达因缺油造成的不稳定状况。
