The hydraulic winch comprises a rack and a winding drum, the winding drum is rotatably connected with the rack, a planetary reducer, a hydraulic motor and a brake unit are arranged in the winding drum, the output end of the hydraulic motor is in transmission connection with the planetary reducer, and the planetary reducer is connected with the winding drum so as to drive the winding drum to rotate and work. The hydraulic motor, the planetary reducer and the brake unit are all integrated in the winding drum, the planet carrier output shaft is of a hollow structure, and the hydraulic motor is arranged in the hollow structure of the planet carrier output shaft, so that the hydraulic winch is compact in structure, and the size of the hydraulic winch is reduced. Meanwhile, the high-speed end brake and the low-speed end brake are both normally-closed self-locking brakes, the hydraulic motor is in a braking state when not working, and when the hydraulic motor stops working, the high-speed end brake and the low-speed end brake are both automatically locked, and the winding drum stops rotating; the low-speed end brake directly brakes the reel, and safety and reliability of the device are improved.

    本发明公开一种液压绞车,包括机架和卷筒,卷筒可转动地与机架相连,卷筒内设置有行星减速器、液压马达和制动器单元,液压马达的输出端与行星减速器传动相连,行星减速器与卷筒相连,从而带动卷筒转动工作,液压马达、行星减速器以及制动器单元均集成于卷筒内,且行星架输出轴为中空结构,液压马达设置于行星架输出轴的中空结构内,使得液压绞车结构紧凑,减小了液压绞车的体积。与此同时,高速端制动器和低速端制动器均为常闭式自锁制动器,液压马达不工作时处于制动状态,液压马达停止工作时,高速端制动器和低速端制动器均自动锁闭,卷筒停止转动,当行星减速器或液压马达损坏时,低速端制动器直接制动卷筒,提高了装置的安全可靠性。
