A hydraulic winch emergency system of a rescue boat retracting and releasing device comprises a hydraulic motor, a brake connected with the hydraulic motor, a motor valve group for controlling the hydraulic motor to rotate, a control valve group for conveying hydraulic oil to the motor valve group, a hydraulic pump for inputting the hydraulic oil into the control valve group from an oil tank, and an emergency pump group. An oil inlet of the emergency pump set is connected with the oil tank, and an oil outlet of the emergency pump set is connected with an oil inlet of the control valve set. A stop valve and an emergency reversing valve are arranged between the control valve set and the motor valve set, the stop valve is located between the control valve set and a port A of the motor valve set, and after the stop valve closes an oil way, hydraulic oil going to the port A of the motor valve set enters the motor valve set through the emergency reversing valve. Through the arrangement of the emergency pump set, the stop valve and the emergency reversing valve, efficient and convenient use of the hydraulic winch under the emergency condition is achieved.

    一种救助艇收放装置液压绞车应急系统包括液压马达,与液压马达连接的制动器,控制液压马达转动的马达阀组,将液压油输送至马达阀组的控制阀组,以及将液压油自油箱输入控制阀组的液压泵,以及应急泵组;应急泵组进油口与油箱连接,应急泵出油口与控制阀组的进油口连接;控制阀组与述马达阀组之间设置有截止阀和应急换向阀,截止阀位于控制阀组和马达阀组A口之间,截止阀关闭油路后,前往马达阀组A口的液压油经应急换向阀进入马达阀组。本发明通过应急泵组,截止阀和应急换向阀的设置,实现了应急情况下液压绞车的高效便捷使用。
