The invention relates to the technical field of lifting hooks, in particular to a crane arc unhooking prevention device with a balance protection function, which comprises a positioning frame, the bottom of the positioning frame is of an opening structure, a cylinder is arranged at the center of the inner wall of the top of the positioning frame, a push rod is arranged at the output end of the bottom of the cylinder, and a sliding frame is fixedly mounted at the bottom of the push rod; lifting frames are slidably connected to the positions, close to the two sides, of the center in the sliding frame correspondingly, the bottoms of the lifting frames extend out of the positioning frame, and the two lifting frames are in mirror symmetry relative to the central axis of the sliding frame. According to the invention, through the arrangement of the positioning frame, the lifting frame and the anti-falling mechanism, double hooking of the binding rope is realized, the unhooking phenomenon is prevented, the situation that the material is inclined and unstable due to concentrated lifting of the binding rope at the center of the material is avoided, the lifting efficiency is improved, and the balance mechanism is arranged and is matched with the push rod, so that the lifting efficiency is improved. And the two ends of the hoisted object are further pressed and limited, the balance of the material during hoisting is kept, and the hoisting efficiency is improved.

    本发明涉及吊钩技术领域,具体为具有平衡保护功能的行车圆弧防脱钩装置,包括定位框,定位框底部呈开口结构,且定位框顶部内壁中心处设置有气缸,气缸底部输出端设置有推杆,且推杆底部固定安装有滑框,滑框内部中心靠近两侧处分别滑动连接有起吊框,且起吊框底部延伸至定位框外部,两组起吊框相对滑框中心轴线呈镜像对称;本发明是通过设置定位框、起吊框及防脱机构,不仅实现对捆绳的双重钩取,防止脱钩现象,并避免集中对物料中心捆绳起吊而导致物料倾斜不稳定的情况,提高起吊的效率,还通过设置平衡机构,其与推杆配合,进一步实现对起吊物两端处抵压限定,保持物料起吊时的平衡,提高起吊效率。
