The invention discloses a structure for preventing a lift car from accidental movement. The structure comprises a lift car and a traction machine for driving the lift car, wherein two groups of sensors which are arranged up and down are arranged on each flat layer; the lift car is provided with a magnetism separation plate capable of triggering the sensors and a safety clamp for clamping a guide rail; the structure further comprises a control device which is electrically connected with the sensors, the safety clamp and the traction machine. The safety clamp is mounted on the lift car so that the safety clamp is triggered to clamp the guide rail when a band-type brake is invalid and the controller detects that the lift car has the accidental movement, and furthermore, the lift car cannot continually move and the utilization safety of the lift car is improved.
