The invention belongs to the technical field of hydraulic winches, and particularly relates to a double-speed hydraulic winch. The double-speed hydraulic winch comprises a frame body, a winch roller rotationally assembled on the frame body, a planetary reducer in transmission connection with the winch roller and a hydraulic motor fixed to the frame body and in transmission connection with the planetary reducer, and the hydraulic motor is a two-point type variable displacement motor and has a high-speed state and a low-speed state. The hydraulic motor is connected with a hydraulic valve block, and the hydraulic valve block is connected with a high-low speed switching valve used for switching the hydraulic motor between a high-speed state and a low-speed state. According to the double-speed hydraulic winch, the hydraulic motor can be switched between a low-speed state and a high-speed state, small and light goods can be rapidly lifted through a high-speed gear, large and heavy goods can be lifted through a low-speed gear, and the working efficiency of the double-speed hydraulic winch is improved.

    本发明属于液压绞车技术领域,尤其涉及双速液压绞车。双速液压绞车,包括架体、转动装配在架体上的绞车滚筒、与绞车滚筒传动连接的行星减速机以及固定在架体上并与行星减速机传动连接的液压马达,所述液压马达为两点式变量马达,具有高速状态和低速状态;所述液压马达上连接有液压阀块,液压阀块上连接有用于将液压马达在高速状态与低速状态之间进行切换的高低速切换阀。本发明能实现液压马达在低速和高度两种状态的切换,对于小的轻便货物可以使用高速档快速提升货物,对于大件、重件的货物可以使用低速档起重,提高了双速液压绞车的工作效率。
