Fabricated building wallboard hoisting device

The invention relates to the technical field of hoisting equipment, in particular to a fabricated building wallboard hoisting device which comprises a frame body and a hoisting rod, a mounting plate is movably arranged in the frame body, a hoisting ring is arranged at the end of the hoisting rod, a frame body is arranged on the outer wall of the frame body, a fixed pulley is arranged on the outer wall of the frame body, and a steering mechanism is arranged on the hoisting rod. A lifting rope is arranged on the steering mechanism and connected to the inner wall of the fixed pulley in a wound mode, and a downward pressing mechanism is arranged at the end of the lifting rope. The clamping mechanism moves downwards to clamp the building wallboard until the building wallboard makes contact with the outer wall of the frame body, at the moment, the abutting mechanism applies certain force to the building wallboard, the stability of the building wallboard after fixing is effectively guaranteed, in the lifting process
