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.
