The invention discloses a steel beam hoisting device for steel structure site construction, and relates to the technical field of hoisting, the steel beam hoisting device comprises a hanging rod, a connecting block, a hook and a hoisting cable, one end of the hook is fixedly connected with the connecting block, and a hoisting opening is formed between the other end of the hook and the connecting block; a closed groove is formed in the side, close to the hoisting opening, of the connecting block. A reverse blocking device is arranged at the bottom in the closed groove. A sliding groove is formed in the hook; an opening is formed in the side, close to the hoisting opening, of the hook; a sealing rod is slidably connected into the sliding groove, and a plurality of teeth are fixedly arranged on the inner ring face of the sealing rod. The hook is further provided with a control groove and a release groove, the control groove is formed in the inner ring face of the hook, and the release groove is formed in the outer ring face of the hook. A connecting column is fixed in the control groove, and a sealing belt is fixed on the connecting column; the technical effects that the hook can be automatically closed, and the hook is still kept closed when the clamping block breaks down are achieved.
