The invention discloses a crane lifting hook capable of keeping horizontal and achieving emergency clamping and dropping. The crane lifting hook comprises a lifting hook, a shock absorption block is fixedly arranged on the upper end face of the lifting hook, a balance cavity is arranged in the lifting hook, a balance wheel with the high degree of freedom is arranged in the balance cavity, a sliding cavity which is symmetrical left and right and symmetrical front and back is arranged in the balance wheel, a sliding ball capable of sliding is arranged in the sliding cavity, and a clamping groovewith an upward opening is arranged on the upper side in the balance wheel. Through the shock absorption effect on the crane lifting hook, the vibration of a crane is reduced in the lifting process, and meanwhile, the weight carried by the lifting hook is balanced and adjusted, so that the lifting work is safer and more stable; then, the device has emergency measures for tying rope breaking in anemergency situation, a tying rope is instantly tightened at the moment of rope breaking to prevent weight falling, and potential safety hazards caused by weight falling in sudden accidents are reducedby the lifting hook.

    本发明公开的一种能保持水平并应急夹紧降落的起重机吊钩,包括吊钩,所述吊钩上端面固定设有减震块,所述吊钩内设有平衡腔,所述平衡腔内设有自由度较高的平衡轮,所述平衡轮内设有左右对称与前后对称的滑动腔,所述滑动腔内设有能滑动的滑动滚珠,所述平衡轮内上侧设有开口向上的装卡槽,本发明通过对起吊机吊钩的减震效果,使起吊机在起吊过程中使振动减少,并且同时对吊钩吊载的重物进行平衡调节,使起吊工作更加安全稳定性更高,随后本装置对突发状况的绑绳断裂有应急措施,并在断绳瞬间将绑绳瞬间拉紧组织了重物掉落,使吊钩在面对突发性事故使减少重物掉落带来的安全隐患。
