The invention relates to the technical field of cranes, and discloses an anti-moving device of a crane hook. The anti-moving device comprises a fixed block, a positive plate is fixedly connected to the inner wall of the left side of the fixed block, a negative plate is movably connected to the right side of the fixed block, a fixed seat is fixedly connected to inisde the fixed block, and a movable groove is formed in the fixed seat; and a connecting spring is movably connected into the movable groove, and a limiting groove is formed in the movable groove. According to the anti-moving device of the crane hook, when the hook is subjected to the gravity action of a heavy object, a movable block moves downwards to drive a dielectric plate to move downwards, so that the relative area between the positive plate and the negative plate is increased, a little current is generated between the positive plate and the negative plate, an electrorheological fluid solution is changed into a solid state from a liquid state to fix a hanging rope, the hook is safer and more stable in the hanging and taking process, safety is improved, object losses caused by falling of the heavy object are avoided, and the carrying cost is saved.

    本发明涉及起重机技术领域,且公开了一种起重机吊钩的防移动装置,包括固定块,所述固定块的左侧内壁固定连接正极板,所述固定块的右侧活动连接有负极板,所述固定块的内部固定连接有固定座,所述固定座的内部开设有活动槽,所述活动槽内部活动连接有连接弹簧,所述活动槽的内部开设有限位槽。该起重机吊钩的防移动装置,通过挂钩受到重物的重力作用时,使得活动块向下移动,带动电介质板向下移动,使得正极板与负极板之间相对面积增大,正极板与负极板之间有点电流产生,电流变体溶液由液态变为固态,对挂绳进行固定,使得吊钩在挂取的过程中更安全稳定,提高了安全性,避免重物脱落导致物体损耗,节省了搬运成本。
