The invention relates to the technical field of hydraulic winches, and discloses a hydraulic winch for underwater lifting of a ship crane. The hydraulic winch comprises a base, wherein the left side of the top of the base is fixedly connected with the bottom of a bidirectional hydraulic cylinder, the output end of the left side of the bidirectional hydraulic cylinder is fixedly connected with theright end of a push rod, the left end of the push rod is fixedly connected with the middle of a piston plate, and the outer side wall of the piston plate is slidably connected with the inner wall of an oil cylinder. According to the hydraulic winch for underwater lifting of the ship crane, the output end of a hydraulic motor drives a driving gear to rotate while driving a rotating shaft and a winding shaft to rotate, and the driving gear is matched with two sets of driven gears, so that a rotating disc drives a shifting rod to shift a stepping seat to rotate by 90 degrees in the rotating process; and through the guiding effect of a sliding rod on a sliding groove and the threaded fit of a lead screw and a screw seat, the screw seat moves by one fourth of the screw pitch length every time,the arrangement direction of steel wires is conveniently controlled, and the situation that the steel wires are staggered and separated when wound on the winding shaft is avoided.
本发明涉及液压绞车技术领域,且公开了一种船吊水下提升用液压绞车,包括底座,所述底座顶部的左侧与双向液压缸的底部固定连接,所述双向液压缸的左侧输出端与推杆的右端固定连接,所述推杆的左端与活塞板的中部固定连接,活塞板的外侧壁与油缸的内壁滑动连接。该船吊水下提升用液压绞车,通过液压电机的输出端带动转轴和缠绕轴转动的过程中同时带动主动齿轮转动,以及主动齿轮与两组从动齿轮的配合,使得转盘在转动的过程中带动拨杆拨动步进座旋转九十度,又通过滑杆对滑槽的导向作用,以及丝杠与丝座的螺纹配合,进而使得丝座每次移动均位移螺距长度的四分之一,方便控制钢丝的排布方向,避免钢丝在缠绕轴上缠绕时产生错叠和离缝。
