Device and method for mounting pressure steel pipe joints in vertical shaft

The invention discloses a device and a method for mounting a pressure steel pipe joint in a vertical shaft and belongs to the technical field of pressure steel pipes. The device comprises a vertical shaft hanging bracket arranged at the mouth of the vertical shaft, a winch hoisting steel wire rope is wound on the vertical shaft hanging bracket through a hoisting fixed pulley and is connected with the output end of a winch; the tail end of the winch hoisting steel wire rope bypasses the hoisting fixed pulley and then is fixedly connected with a balance beam assembly, the lower end of the balance beam assembly is fixedly connected with a pipe joint, the balance beam assembly comprises an upper beam and a lower beam, the upper beam is fixedly connected with the tail end of the winch hoisting steel wire rope, and the lower beam is fixedly connected with a hoisting ring at the upper end of the pipe joint. By using the device and the method, the rotating lifting hook in the balance beam assembly rotates to meet the
