The invention relates to the technical field of lifting appliances, in particular to a clamping jaw type lifting appliance for vertically lifting a drill rod of a large vertical shaft drilling machine. Comprising a hoisting connecting frame, a hoisting cylinder, a clamping jaw and a driving part, the top of the hoisting connecting frame is connected with a hook of the hoisting machine, and the bottom of the hoisting connecting frame is connected with the top of the hoisting cylinder; one end of each clamping jaw is hinged to the inner wall of the hanging barrel, and the other end of each clamping jaw is used for being connected with the end of a drill rod in a clamped mode. And the driving part is used for pushing the clamping jaw to rotate until the clamping jaw is vertically connected with the inner wall of the hanging barrel. The lifting appliance not only can stably clamp the drill rod at the same time, is convenient to lift and improves the lifting efficiency, but also is simple in structure and easy to use.

    本发明涉及吊具技术领域,尤其涉及一种用于大型竖井钻机垂直吊运钻杆的卡爪式吊具。包括:吊装连接架、吊筒、卡爪和驱动部;所述吊装连接架顶部与起吊机的挂钩连接,吊装连接架的底部与吊筒的顶部连接;所述卡爪的一端与吊筒的内壁铰接,卡爪的另一端用于卡接钻杆的端部;所述驱动部用于推动卡爪转动,直至卡爪与吊筒的内壁形成垂直连接。该吊具不仅可以同时钻杆进行稳定卡接,便于吊装,提升吊装效率,而且结构简单,易于使用。
