The hydraulic winch comprises a capstan, the capstan comprises a winding drum and annular baffle discs at the two ends, the inner wall of the left side of the winding drum is fixedly connected with a capstan combiner, a center shaft is arranged in the winding drum, the center shaft is sequentially provided with a spline sleeve, a clutch spring and an oil cylinder body from left to right, and the spline sleeve is telescopically connected with a spline shaft of a hydraulic motor; a spline housing combiner corresponding to the winch combiner is mounted on the spline housing; a piston body is mounted in the oil cylinder body; the piston body is driven by the hydraulic system to drive the center shaft and the spline housing to slide left and right, then gear engaging and gear disengaging operation of the winch combiner and the spline housing combiner can be achieved, the hydraulic motor drives the spline housing to rotate, rope winding lifting operation is carried out in the gear engaging state, and free rope unwinding operation is carried out in the gear disengaging state. Comprising a rope releasing brake mechanism which is automatically started and can adjust the magnitude of braking force. The device is compact in structure and small in occupied space, and free rope releasing and lifting traction operation can be remotely operated by operating a hydraulic system.
本发明公开了一种液压绞车,它包括绞盘,绞盘包括卷筒和两端的圆环挡盘,卷筒左侧内壁固定连接绞盘结合子,卷筒内部设有中心轴,中心轴从左到右依次安装有花键套、离合弹簧和油缸体,花键套与液压马达的花键轴可伸缩连接,花键套上安装与绞盘结合子相对应的花键套结合子,油缸体内安装活塞体;通过液压系统驱动活塞体连带中心轴和花键套左右滑动,进而可以实现绞盘结合子和花键套结合子挂挡和脱挡操作,液压马达驱动花键套旋转,在挂挡状态时进行卷绳提升作业,在脱挡状态时进行自由放绳作业,包括的放绳制动机构自动启动并可调节制动力的大小。它结构紧凑,占地空间小,通过操作液压系统能远距离操作自由放绳和提升牵引作业。
