The invention discloses an anti-swing device for a crane lifting appliance. The anti-swing device comprises a connecting assembly, an anti-swing assembly arranged at the lower end of the connecting assembly, a cushioning assembly arranged at the lower end of the anti-swing assembly and a lifting assembly penetrating through the anti-swing assembly and the cushioning assembly and arranged at the lower end of the connecting assembly; the anti-swing assembly comprises a sliding block, communicating holes are formed in the two symmetrical side faces of the sliding block, a balance rod is embedded in the communicating holes, and balance weight plates are fixedly arranged at the two ends of the balance rod; a first through hole is formed in the upper side surface of the sliding block; and a positioning plate is arranged at the lower end of the sliding block, the positioning plate and the sliding block are fixedly connected through a connecting column, and a positioning groove is formed in the positioning plate. A limiting pipe with a smooth inner wall is arranged between the first through hole and the positioning groove, and the lifting assembly sequentially penetrates through the first through hole, the limiting pipe and the positioning groove, so that the anti-swing effect is achieved; and the anti-swing assembly is only arranged at the top of the crane, so that an overlong and overlarge guide rod is not needed.

    本发明公开了一种起重机吊具防摇摆装置,包括连接组件、设置在连接组件下端的防摆动组件、设置在防摆动组件下端的缓震组件及贯穿防摆动组件和缓震组件设置在连接组件下端的起吊组件;其中,防摆动组件包括滑动块,滑动块相对称的两个侧面上设有连通孔,连通孔内嵌有平衡杆,且平衡杆的两端固定安装有配重板;滑动块的上侧面开设有第一通孔;滑动块的下端设置有定位板,定位板与滑动块之间通过连接柱固定连接,且定位板上开设有定位槽,第一通孔与定位槽之间设置有内壁光滑的限位管,起吊组件依次贯穿第一通孔、限位管和定位槽,实现了防摆效果,且防摆动组件仅仅设置在起重机的顶部,因此无需过长且过大的导杆。
