The invention discloses a crane lifting head with a cable breakage emergency stop function. The crane lifting head with the cable breakage emergency stop function comprises a lifting head main body; a lifting transmission cavity with an upward opening is formed in the lifting head main body; a lifting rotating wheel is rotatably arranged in the lifting transmission cavity; a lifting cable is fixedly connected to the outer circular surface of the lifting rotating wheel; and the axis of the lifting rotating wheel is fixedly connected with a hoisting rotating shaft. According to the crane lifting head, a heavy object cable is clamped before lifting; the effect of stably clamping the heavy object cable is achieved; the heavy object lifting efficiency is higher; the gravity center is adjusted after the lifted heavy object is stably placed, so that the gravity center balance effect of the crane lifting head is achieved; the stability of lifting work is improved; the heavy cable can be clamped instantly when the heavy object cable is broken, and the falling speed of the heavy object cable is decreased; meanwhile, the lifting cable can be clamped instantly when the lifting cable is broken; and accidents are reduced.

    本发明公开的一种具有缆绳断裂急停功能的起重机吊头,包括吊头主体,所述吊头主体内设有开口向上的起重传动腔,所述起重传动腔内转动设有起重转轮,所述起重转轮外圆面固定连接有起重缆绳,所述起重转轮轴心固定连接有起重转轴,本发明通过将重物缆绳在起重前进行夹紧,达到了稳定装夹重物缆绳的效果使提升重物效率更高,并在稳定放置起重重物后进行重心的调整使起重机吊头达到重心平衡的效果,提高起重工作的稳定性,且本发明在重物缆绳断裂时能瞬间进行重物缆绳进行装夹并减缓重物掉落的速率,同时本发明能在起重缆绳断裂时将起重缆绳进行瞬时装夹,减少了事故的发生。
