The invention relates to the technical field of anchor cable braiding, and discloses a birdcage anchor cable braiding device and a use method. The birdcage anchor cable braiding device comprises a winch and a positioning ring, wherein a first through hole is formed in the surface of the winch, the first through hole is used for arranging a central strand of the anchor cable in a penetrating mode,a plurality of second through holes are formed around the first through hole, the second through holes are used for arranging side strands of the anchor cable in a penetrating mode, the winch can rotate around the first through hole, and one end of the central strand is arranged in the positioning ring in a penetrating mode. According to the birdcage anchor cable braiding device and the use method, the central strand and the side strands of the anchor cable are correspondingly arranged in the first through hole and the second through holes of the winch in a penetrating mode, the separation ofmultiple strands of the anchor cable is realized in a parallel state by rotating the winch, the positioning ring sleeves the periphery of the central strand, and then the winch is reversely rotated torealize the restoration of a spiral winding state of the anchor cable. The birdcage anchor cable is prepared by using the birdcage anchor cable braiding device, operation is easy, the production efficiency is high, and the birdcage anchor cable braiding device is suitable for the needs of large-scale production; and bird cages in the prepared birdcage anchor cable are supported by the positioningring, and the problems that position deviation and loose deformation are not prone to producing are solved.
