The bidirectional speed limiter comprises a connecting structure, a guide rail and two speed limiting wheels, the two speed limiting wheels are rotatably arranged on the two sides of the connecting structure respectively, and the two speed limiting wheels are arranged on the two sides of the guide rail in a rolling mode respectively; the speed limiting wheel comprises a wheel body, an inner frame body, a centrifugal moving mechanism and a trigger switch, the inner frame body is arranged in the wheel body, the centrifugal moving mechanism and the trigger switch are both installed on the inner frame body, and the centrifugal moving mechanism is used for driving the trigger switch to conduct trigger action under the action of centrifugal force. Through the application of the bidirectional speed limiter, the bidirectional speed limiter suitable for the high-speed elevator is provided, and the speed limiting requirement when the ascending speed and the descending speed of the elevator are different can be met; the device is simple in structure and good in reliability in the working process.
