The invention relates to a crane sling anti-swing device in the technical field of cranes, and the crane sling anti-swing device comprises a crane trolley, a sling with a movable pulley, a steel wire rope and a control system, the crane trolley is provided with a winding drum assembly for winding and unwinding the steel wire rope, and one end of the steel wire rope is wound and fixedly connected to the winding drum assembly; a pin shaft is fixedly connected to the middle of the swing rod, the swing rod is correspondingly hinged to the crane trolley through the pin shaft, and the two ends of the swing rod abut against the two vertical sections of the steel wire rope respectively, so that the steel wire rope deflects to drive the pin shaft to rotate; when the lifting appliance swings, the steel wire rope applies acting force opposite to the swinging direction of the lifting appliance to the lifting appliance in a manner of winding and unwinding the steel wire rope through the winding drum assembly, so that the swinging amplitude of the lifting appliance is reduced, and the function of preventing the lifting appliance from swinging is further realized; and workshop space cannot be wasted.
本发明涉及起重机技术领域的一种起重机吊具防摇摆装置,包括起重机小车、具有动滑轮的吊具、钢丝绳和控制系统,所述起重机小车安装有收放卷钢丝绳的卷筒组件,所述钢丝绳一端缠绕并固接于卷筒组件,另一端绕过动滑轮对应连接于起重机小车,还包括:摆动杆,中部固接有销轴、且通过销轴对应铰接于起重机小车,摆动杆两端部分别抵触于钢丝绳的两个竖直段,以便于钢丝绳偏斜带动销轴转动;本发明在吊具发生摇摆时,通过卷筒组件收放卷钢丝绳的方式,使得钢丝绳对吊具施加朝向与吊具发生摆动方向相反的作用力,而减小吊具摇摆幅度,进而实现防止吊具摇摆的功能,相比于通过设置上下伸缩结构防止吊具摇摆的方式来讲,不会浪费车间空间。
