Pneumatic elevator and leveling mechanism thereof

The utility model discloses a pneumatic elevator and a leveling mechanism thereof. The leveling mechanism of the pneumatic elevator comprises a motor, a gear mechanism, a cam mechanism and a leveling ejector rod. The motor is connected with a control system of the pneumatic elevator and drives the can mechanism to move through the gear mechanism. One end of the leveling ejector rod makes contact with the cam mechanism, and the other end of the leveling ejector rod corresponds to a leveling notch of a guide rail. A fixing part is arranged on the leveling ejector rod and fixedly connected with a car. When the motor receives a leveling instruction of the control system, the leveling ejector rod is embedded into the leveling notch of the guide rail by means of transmission of the cam mechanism. On the basis of the stroke reversal stop principle, the leveling ejector rod will not reversely move under the effect of external force, the problem that an existing pneumatic elevator is unstable in leveling is solved, and the elevator leveling reliability is improved. After leveling, the phenomenon that the car is automatically unlocked when ascending or descending on abnormal conditions is avoided.
