The invention discloses a steel wire rope protection device and a rotary drilling rig. The steel wire rope protection device comprises a support mechanism and a rotary mechanism, wherein the rotary mechanism comprises a supporting portion and a rotary portion. The supporting portion is installed on the support mechanism. The rotary portion is rotatably installed on the supporting portion and provided with a rope through hole for a steel wire rope to penetrate through, and a brush is arranged on the inner wall of the rope through hole. When the steel wire rope protection device is used, the steel wire rope penetrates through the rope through hole of the rotary portion and is in contact with the brush in the rotary portion. The steel wire rope performs axial motion, the rotary portion performs peripheral rotation, the steel wire rope and the brush produce relative motions, the brush brushes off silt and other foreign matter on the surface of the steel wire rope to achieve the steel wire rope surface cleaning effect, a protection role is played on the steel wire rope, and the service life of the steel wire rope is prolonged.
