The invention discloses a lifting safety device for a lifting hook, and belongs to the technical field of lifting hook equipment. The lifting safety device for the lifting hook comprises a movable plate, a rotating shaft connecting base is fixedly connected to the bottom end of the movable plate, a rotating shaft is movably connected to the interior of the rotating shaft connecting base, and the bottom end of the rotating shaft is fixedly connected with a rotating shaft receiving base. According to the lifting safety device for the lifting hook, due to the arrangement, when the lifting hook is used, a baffle plate is firstly pressed downwards, at the moment, a spring contracts, the baffle plate is loosened after an object needing to be lifted is hooked, then the spring expands, the baffle plate resets, so that the hooked object is encircled by the lifting hook and the baffle plate, the baffle plate can prevent the hooked object from falling off, a baffle block can prevent the baffle plate from falling off from the lifting hook due to violent shaking, thus the stability of the baffle plate is enhanced, meanwhile, an anti-skidding block can increase the friction force between the lifting hook and the hooked object, and thus the shaking of the hooked object in the lifting hook is reduced.

    本发明公开了一种吊钩起重安全装置,属于起重吊钩设备技术领域,一种吊钩起重安全装置,包括活动板,所述活动板的底端固定连接有转动轴连接底座,所述转动轴连接底座的内部活动连接有转动轴,所述转动轴的底端固定连接有转动轴接收底座。该吊钩起重安全装置,通过设置在使用吊钩时,首先先下压挡板,这时弹簧会收缩,钩挂所需要起重的物品完成后松开挡板,弹簧会张开,挡板会复位,这样钩挂的物品会被吊钩和挡板圈起来,挡板能够阻止所钩挂的物品脱落,阻挡块能够避免挡板因剧烈晃动从吊钩上脱落,加强挡板的稳定性,防滑块能够增大吊钩与所钩挂的物品之间的摩擦力,减少钩挂的物品在吊钩的内部晃动。
