The invention provides a car elevator fault emergency rescue system which comprises a walking system, a locking system and a rack, and the walking system and the locking system are connected together through the rack. Two transfer case bodies are connected below the motor; the left and right sides of the two transfer case bodies are respectively connected with worms in the left walking system and the right walking system through connecting devices; the worm is provided with two turbines, two turbine shafts are connected with rollers, and the rollers rotate around the shafts and are driven by a motor to move up and down; two sides of a bidirectional ball screw in the locking system are provided with threads and are screwed with a screw nut, a middle groove is connected with a middle inner hook of a torsion spring, two ends of the spring are arranged on the screw nut, and the bidirectional ball screw is rotated to apply force to the torsion spring so as to lock the device; the left end and the right end of the bidirectional ball screw are provided with steel wire rope wheels, and steel wire ropes are wound on the rope wheels and provided with hooks connected with an elevator. Under the conditions that the lift car elevator breaks down suddenly and the self-help rescue system cannot work normally, the system lifts the lift car to a flat layer to rescue trapped people.
