The invention discloses a peak shifting slide way type automatic hooking and unhooking lifting device which comprises a lifting lug and a base. The lifting lug and the base are respectively arranged on an upper beam body and a lower beam body of the lifting appliance; swing rod assemblies are hinged to the bottoms of the lifting lugs; a plurality of peak shifting slideways are formed in the base, and the bottom end of the swing rod assembly is detachably connected with the peak shifting slideways; one side of the inner wall of the peak shifting slide way is rotationally connected with a one-way shifting piece assembly; the top point of the inner top wall of the peak shifting slide way is located under the swing rod assembly, and the top point of the inner bottom wall is arranged on the side away from the one-way shifting piece assembly; the top face of the base is inclined, and the high end of the top face of the base and the one-way shifting piece assembly are located on the same side. The automatic hook unhooking device is applied to opening and closing actions of a lifting sling, automatic hook unhooking can be achieved, the hook is effectively prevented from being opened in the air in the locked state, the safety and reliability of lifting are improved, the structure is simple, and manufacturing and maintenance are convenient.
本发明公开一种错峰滑道式自动挂钩脱钩起重装置,包括吊耳和底座;吊耳和底座分别安装在起重吊具的上梁体和下梁体上;吊耳底部铰接有摆杆组件;底座内开设有若干错峰滑道,摆杆组件底端与若干错峰滑道可拆卸连接;错峰滑道内壁一侧转动连接有单向拨片组件;错峰滑道的内顶壁顶点位于摆杆组件的正下方,内底壁顶点设置在远离单向拨片组件的一侧;底座的顶面倾斜设置,并且底座顶面高端与单向拨片组件位于同侧。本发明应用于起重吊具的开闭动作,可实现自动挂钩脱钩,并有效避免挂钩闭锁转态下在空中打开,提高吊装的安全可靠性,结构简单、便于制造和维护。
