本发明公开了一种针对船舶不同的装载情况实现自动收放缆绳的液压绞车钢丝绳恒张力控制系统,包括进油总管、回油总管、主控阀阀组、恒张力阀组和液压马达组,主控阀阀组和恒张力阀组的进油端口分别通过管路与进油总管连接、出油端口分别通过管路与液压马达组的马达进油主管连接;液压马达组的马达回油主管与主控阀阀组的回油进口连接,主控阀阀组的回油出口与回油总管连接;主控阀阀组上设置有使得液压马达组在恒张力和主控两个状态间切换的换向手柄;恒张力阀组包括并列设置的至少两个对应不同负载档位的自动阀组,自动阀组包括沿出油方向通过管路依次连接的换向阀和三通减压阀,三通减压阀的泄油口通过泄油支管与回油总管相连接。

    The invention discloses a constant tension control system for a steel wire rope of a hydraulic winch, which can automatically take up and pay off the steel wire rope according to different loading conditions of ships, and comprises an oil inlet header pipe, an oil return header pipe, a main control valve group, a constant tension valve group and a hydraulic motor group, oil inlet ports of the main control valve group and the constant tension valve group are respectively connected with an oil inlet main pipe through pipelines, and oil outlet ports of the main control valve group and the constant tension valve group are respectively connected with a motor oil inlet main pipe of the hydraulic motor group through pipelines; a motor oil return main pipe of the hydraulic motor set is connected with an oil return inlet of the main control valve set, and an oil return outlet of the main control valve set is connected with an oil return main pipe. The main control valve group is provided with a reversing handle which enables the hydraulic motor group to be switched between a constant tension state and a main control state. The constant tension valve group comprises at least two automatic valve groups which are arranged in parallel and correspond to different load gears, each automatic valve group comprises a reversing valve and a three-way pressure reducing valve which are sequentially connected through a pipeline in the oil outlet direction, and an oil drainage port of each three-way pressure reducing valve is connected with the oil return header pipe through an oil drainage branch pipe.
