The invention discloses a detachable drilling lifting hook for hoisting machinery, and relates to the technical field of lifting hooks. The lifting hook comprises a U-shaped hook body, wherein the U-shaped hook body is composed of a bottom frame, a long side edge and a short side edge, the two ends of the bottom frame are fixedly connected with the short side edge and the long side edge respectively, a lead screw is arranged in the bottom frame, the two ends of the lead screw penetrate through the short side edge and the long side edge respectively, a driven sprocket is fixed to the end, located outside the long side edge, of the lead screw, and the outer surface of the section, located in the bottom frame, of the lead screw is in transmission connection with an inner locking mechanism which is matched with the bottom frame and penetrates through the bottom frame. In the using process of the lifting hook, a structure hung on the lifting hook body can dually locked, so that the firmnessand safety of the lifting hook during hanging are guaranteed; and when the hanging load on the lifting hook needs to be dismantled in use, a stepping motor can be manually controlled to open the inner locking mechanism, and then an anti-disengaging piece is manually loosened, so that the operation is simple and convenient, time is saved, and the working efficiency is improved.

    本发明公开了一种用于起重机械的可拆卸式钻井吊钩,涉及吊钩技术领域。本发明包括“U”形挂钩本体,“U”形挂钩本体由底框、长侧边和短侧边构成,底框两端分别与短侧边、长侧边固定连接,底框内部设置有丝杆,丝杆两端分别贯穿短侧边、长侧边,丝杆位于长侧边外部的一端固定有从动链轮,丝杆位于底框内部的一段外表面上传动连接有与底框配合且贯穿底框的内锁紧机构。本发明在使用时对吊钩本体上悬挂的结构能够进行双重的锁死功能,保证吊钩挂载是的牢固性和安全性;并且在使用需要拆卸吊钩上的挂载时,能够通过手动控制步进电机打开内锁紧机构,然后再手动松开防脱件即可,操作简单方便,节约了时间,提高了工作效率。
