The H-shaped steel beam erecting and lifting device comprises a middle positioning block, the upper end face of the middle positioning block is movably connected with a lead screw in a limiting mode, the upper end face of the lead screw is movably connected with a disc, the upper end face of the disc is fixedly connected with a first shackle, the outer ring of the lead screw is in threaded connection with an adjusting sleeve, and the two sides of the adjusting sleeve are fixedly connected with lug blocks. The side faces of the lug blocks are fixedly connected with folded plates through steel wire ropes, inserting grooves are formed in the folded plates, symmetrically-arranged lead screws are inserted into the side faces of the middle positioning block, the lead screws are slidably connected with L blocks, the lead screws are in threaded connection with locking nuts, and the outer sides of the lead screws are fixedly connected with rotating handles. The two ends of the H-shaped steel beam are clamped and fixed through the folded plates connected with the steel wire ropes on the two sides of the adjusting sleeve, flange plates of the H-shaped steel beam are clamped through the L-shaped blocks on the two sides of the middle positioning block, hoisting and fixing of the H-shaped steel beam are achieved, fixing is stable, safety is high, an auxiliary plate does not need to be pre-welded, construction is convenient and fast, hoisting efficiency is improved, and cost is reduced. And the hoisting device can adapt to hoisting of different H-shaped steel beams.
