The invention discloses an auxiliary arm for stabilizing and preventing swing of a marine crane, and relates to the technical field of marine hoisting equipment, in particular to an auxiliary device for the marine crane. A base is fixedly connected to the tail end of a cargo boom of the marine crane; the tail end of the rotary base is connected with a base hinged shaft and can transversely rotate by taking the hinged shaft as a circle center; an unbalance loading hydraulic cylinder is arranged between the rotary base and the base; the bottom end of the telescopic arm is connected with the rotary base through a hinged shaft and can rotate in a pitching manner by taking the hinged shaft as a circle center; a pitching hydraulic cylinder is arranged between the rotary base and the telescopic arm and is used for providing power for pitching motion of the telescopic arm; the fixed pulley is mounted at the top of the telescopic arm; and the lifting hook is wound on the fixed pulley through a steel wire rope and is connected with a winding drum of the marine crane. According to the technical scheme, the problems that in the prior art, when a ship body of a mother ship shakes, a ship crane moves along with the ship body, then the tail end of a suspension arm moves, and finally goods swing is caused are solved.

    本发明用于船用起重机减摇防摆的辅助臂,涉及船用起重设备技术领域,尤其涉及用于船用起重机上的辅助装置。本发明基座固定连接在船用起重机的起重臂末端;旋转基座的尾端与基座铰轴连接,并可以铰轴为圆心做横向转动;旋转基座与基座之间装有偏载液压缸;伸缩臂的底端与旋转基座通过铰轴连接,并可以铰轴为圆心作俯仰转动;旋转基座与伸缩臂之间装有俯仰液压缸,为伸缩臂提供俯仰运动的动力;定滑轮装于伸缩臂的顶端;吊钩通过钢丝绳缠绕在定滑轮上,并与船用起重机的卷筒相连接。本发明的技术方案解决了现有技术中的当母船发生船体晃动时,船用起重机随船体运动,进而导致吊臂末端的运动,最后导致货物的摆动的问题。
