The invention belongs to a separating device and particularly relates to a safe separating device for a heavy-load lifting hook. A heavy-load lifting hook safe separating device is characterized in that symmetrically-arranged connecting rod mechanisms are adopted, two symmetrically-arranged grabbing hooks are installed on a box body through pin shafts, the tops of the two grabbing hooks are connected with rocker arms with the same length through pin shafts B and C respectively, the two sets of rocker arms are connected with each other through pin shafts D, and therefore the connecting rod mechanisms are formed; a sliding groove allowing the pin shaft D to slide up and down is formed in the center line of the two side plates of the box body, the pin shaft D penetrates through the sliding groove, when the pin shaft D is located at the lowest point of the sliding groove, the pin shaft D is slightly lower than the connecting line of the pin shaft B and the pin shaft C, the two grabbing hooks are closed, and the connecting rod mechanism is in a self-tightening state. The heavy-load lifting hook safe separation device has the remarkable effects of being high in bearing capacity, high in safety, accurate in falling point and high in automation degree.
本发明属于脱离装置,具体涉及重载吊钩安全脱离装置。一种重载吊钩安全脱离装置,采用对称布置的连杆机构,两个对称布置的抓钩通过销轴安装在箱体上,两抓钩的顶部分别通过销轴B/C连接等长的摇臂,两组摇臂通过销轴D相互连接,从而构成连杆机构,在箱体两侧板的中心线上设有供销轴D上下滑动的滑槽,销轴D从中穿过,当销轴D位于滑槽最低点时,销轴D位置稍低于销轴B和销轴C的连线,两抓钩闭合,连杆机构处于自紧状态。本发明的显著效果是:本申请的重载吊钩安全脱离装置承载能力强,安全性高,落点精确,自动化程度高。
