The invention discloses a safety lifting hook for a cable reel. The safety lifting hook comprises a rigid lifting hook body; a lifting hole and a hanging hole below the lifting hole are formed in the front surface of the rigid lifting hook body in a penetrating mode; the hanging hole comprises a transverse hole and a vertical hole, the top of the vertical hole communicates with one end of the bottom of the transverse hole, the bottom of the vertical hole communicates with the bottom end surface of the rigid lifting hook body, and the vertical hole and the rigid lifting hook body form a reverse 7-shaped hanging hole. The special lifting hook matched with the thickness and the protruding length of the process disc edge is manufactured by utilizing the process disc edge structure, so that the rotary mounting structure and the process disc edge realize self-locking under the dead weight of the process disc by utilizing rotary mounting and dismounting of a mechanical structure when the process disc edge is lifted and stressed after being mounted, additional anti-skidding and locking structures are not needed, the whole device is simple and easy to use, the problem that a traditional lifting belt is poor in safety can be solved, meanwhile, the lifting steps are simplified, and the working efficiency is greatly improved.

    本发明公开了一种电缆盘用安全吊钩,包括刚性挂钩本体,所述刚性挂钩本体正面分别贯穿开设有吊孔和吊孔下方的挂孔;所述的挂孔包括有横孔和竖孔,竖孔的顶部与横孔的底部一端相通,竖孔的底部与刚性挂钩本体的底部端面相通,且二者构成反向7字型挂孔。本发明通过利用工艺盘盘沿结构,制作与工艺盘盘沿的厚度和凸出长度配合的专用吊钩,从而利用机械结构的旋转安装和拆卸,安装完毕后吊起受力时,旋转安装结构与工艺盘盘沿在工艺盘的自重下实现自锁,从而无需额外的防滑和锁定结构,使整个装置简单好用,不仅能够解决传统吊装带安全性差的问题,同时,也简化了吊装步骤,大大提高了工作效率。
