The invention discloses a steel wire rope pull-up type power catwalk anti-falling device. Three double-lug plates are welded on a central beam of a power catwalk slope; each double-lug plate is hinged with one limiting plate separately; each limiting plate is hinged with a drawbar; the lowest limiting plate is hinged with a double-hinge chain II; the other end of a double-hinge chain II is hinged with a double-hinge chain I; the other end of the double-hinge chain I is hinged with a regulating bolt; a pair of guide barrel fixing bases is welded on another two beams of the power catwalk slope; each guide barrel fixing base is separately hinged with a guide barrel; a compression spring is arranged in each guide barrel in a sleeved manner; a guide rod is arranged in each compression spring in the sleeved manner; the front ends of the two guide rods are fixedly connected with a pulley shaft; a pulley block is arranged on the pulley shaft in the sleeved manner; the pulley shaft is hinged with the front end of the drawbar; and the rear end of the drawbar is in transmission connection with the double-hinge chain II through a limiting plate I. The steel wire rope pull-up type power catwalk anti-falling device is compact in structure and is reliable in work.
