The invention discloses a winch hydraulic system for a lifeboat of a ship, which comprises a motor pump group oil tank assembly, a hand pump assembly, an energy accumulator assembly, a first control valve group, a second control valve group, a third control valve group and a lifeboat hydraulic winch unit, and the hand pump assembly is arranged on an oil tank; the motor pump set oil tank assembly comprises a motor pump set, and when an electric power system is normal, the motor pump set oil tank assembly supplies oil to the first control valve set, the second control valve set and the third control valve set through the motor pump set to control the lifeboat hydraulic winch unit to act. When the hydraulic winch unit of the lifeboat is in a stop state, the motor pump set oil tank assembly supplements oil to an energy accumulator in the energy accumulator assembly through the motor pump set, so that the energy accumulator keeps set pressure; when the power system breaks down, the hand pump assembly and the energy accumulator assembly jointly supply oil. The lifeboat lifting device has the advantages of being good in safety, stable in lifeboat lifting and labor-saving in manual operation when a power system breaks down.

    本发明公开了一种用于船舶救生艇的绞车液压系统,包括有电机泵组油箱组件、手摇泵组件、蓄能器组件、第一控制阀组、第二控制阀组、第三控制阀组以及救生艇液压绞车单元,所述的手摇泵组件设置于油箱上;电机泵组油箱组件包括有电机泵组,当电力系统正常时,电机泵组油箱组件通过电机泵组给第一控制阀组、第二控制阀组、第三控制阀组供油控制救生艇液压绞车单元动作;当救生艇液压绞车单元处于停止状态时,电机泵组油箱组件通过电机泵组为蓄能器组件中的蓄能器补油,使其保持设定压力;当电力系统出现故障时,手摇泵组件和蓄能器组件合力供油。其优点在于:安全性好,救生艇升降稳定,电力系统出现故障时,手动操作省力。
