The invention provides a steel wire rope protection device and a rotary drilling rig with the same. The steel wire rope protection device comprises a steel wire rope bracket which is arranged on the side, away from a drill stem, of a steel wire rope reel, wherein a steel wire rope is wound around the steel wire rope reel from the side, provided with the steel wire rope bracket, of the steel wire rope reel. The steel wire rope bracket comprises an arc-shaped bearing face which is away from the steel wire rope reel, and the arc radius of the arc-shaped bearing face is larger than the radius of the steel wire rope reel. The back rope outlet rope winding mode is adopted, and therefore damage caused by different magnitudes of bending force borne by the two sides of the steel wire rope in the front rope outlet rope winding mode can be avoided; meanwhile, due to the steel wire rope protection device, the sudden steel wire rope bending caused by the small and medium torque rotary drilling rig in the rear rope outlet mode when masts are laid down and transported can be avoided, the main hoisting steel wire rope is effectively protected, and the service life of the steel wire rope is prolonged.
