The anti-swing device comprises a base, an elastic piece, a large sleeve, a small sleeve and a wheel device, the base is fixed to the lifting appliance used for being connected with a hanging system of a crane in a hanging mode, the large sleeve is arranged on the base, the inner wall of the large sleeve is arranged on the outer wall of the small sleeve in an attached and sleeved mode, and the small sleeve and the large sleeve can stretch out and draw back relatively. The wheel device comprises a mounting seat and a plurality of wheels, the mounting seat is arranged at one end, opposite to the base, of the small sleeve, the wheels are rotatably arranged on the mounting seat, and the wheels can roll along a cross rail used for mounting a walking trolley of the crane; the elastic piece is arranged in the inner cavity of the small sleeve in the vertical direction, one end of the elastic piece is fixed to the base, and the other end of the elastic piece is fixed to the mounting base, so that the problem that a traditional lifting appliance anti-swing device is large in occupied space can be effectively solved, and the lifting appliance anti-swing device is suitable for operation under the low-clearance condition; and meanwhile, the lifting appliance does not shake due to the change of the transverse moving speed of the walking trolley of the crane along the transverse rail, and the anti-shaking effect is better.
本发明公开了一种起重机吊具用防摇装置,包括底座、弹性件、大套筒、小套筒和车轮装置,底座固定于用于与起重机的吊挂系统吊挂连接的吊具上,大套筒设于底座上,大套筒的内壁贴合套设于小套筒的外壁上,小套筒和大套筒可相对伸缩,车轮装置包括安装座和若干车轮,安装座设于小套筒背向底座的一端,车轮可转动地设于安装座上,且车轮能够沿着用于安装起重机的行走小车的横轨滚动,弹性件沿着竖直方向设于小套筒的内腔且一端固定于底座上另一端固定于安装座上,从而能够有效的解决了传统吊具防摇装置高度占空间大的问题,使本发明适用于低净空的情况下作业,同时吊具不会因为起重机的行走小车沿着横轨横移的速度改变而有所晃动,防摇效果较佳。
