The invention relates to the technical field of cranes and specifically discloses an anti-shaking device for a crane. The anti-shaking device for the crane comprises a supporting crossbeam; the bottomsurface of the supporting crossbeam is movably connected with a connecting block through a sliding block and a sliding groove; a supporting shell is arranged on the bottom surface of the connecting block; a lifting rope is movably connected to the bottom face of the supporting shell; a lifting hook block is movably connected to the bottom end of the lifting rope; a traction rope is movably connected to the top face of the lifting hook block through a fixing frame; a connecting frame is fixedly connected to the side face of the supporting shell; and a movable belt wheel is fixedly connected tothe surface, away from the supporting shell, of the connecting frame through a rotating shaft. Through the traction rope and a pull rod, a triangle is formed between the traction rope and the liftingrope in the descending process of the lifting hook block, larger pull force is provided for the side face of the lifting hook block, the lifting hook block is prevented from shaking in the acceleration or deceleration process of equipment, and the effects of reducing the shaking frequency and avoiding affecting normal work of the crane are achieved.
本发明涉及起重机技术领域,具体揭示了一种起重机用防摇晃装置,包括支撑横梁,所述支撑横梁的底面通过滑块与滑槽活动连接有连接块,所述连接块的底面设有支撑壳,所述支撑壳的底面活动连接有起重绳,所述起重绳的底端活动连接有吊钩块,所述吊钩块的顶面通过固定架活动连接有牵拉绳,所述支撑壳的侧面固定连接有连接架,所述连接架远离支撑壳的表面通过转轴固定连接有活动带轮;本发明通过牵拉绳与牵拉杆,使得在吊钩块下降的过程中,让牵拉绳与起重绳之间形成一个三角形,为吊钩块的侧面提供更大的拉力,避免吊钩块在设备加速或减速过程中晃动,达到了降低晃动频率,避免影响吊车正常工作的效果。
