Summary:The utility model discloses a crane steel wire rope off-groove fault detection and protection device which comprises a photoelectric detection infrared emitter and a receiver, the photoelectric detection infrared emitter and the receiver are installed below the vertical face of a fixed pulley block installation base and are oppositely installed and arranged, and the center line of the emitter and the center line of the receiver coincide. A photoelectric detection infrared transmitter and a photoelectric detection infrared receiver are mounted on the outer side of the outer edge of the pulley to prevent the rim from interfering with a light source; and the pulley is arranged below one side of the pulley shaft. When it is detected that the position of the steel wire rope in the direction of the pulley shaft changes, the infrared light source is cut off instantly, meanwhile, the lifting mechanism control protection circuit is cut off in an interlocking mode, and therefore the state of the steel wire rope after d
