Elevator Parking Brake, Method For Operating An Elevator Parking Brake, And Control Device For An Elevator Parking Brake

Abstract: An elevator parking brake, a method for operating an elevator parking brake, and a control device for an elevator parking brake are provided. The elevator parking brake comprises a parking brake frame attachable to an elevator car, a brake pad configured to be brought in contact with a guide rail guiding the elevator car along an elevator shaft, and an actuating mechanism mounted on the parking brake frame, for bringing the brake pad in contact with the guide rail and retracting the brake pad from the guide rail. The actuating mechanism comprises a motor, an actuating member and a conversion mechanism configured to convert a rotational movement of the motor into a linear movement of the actuating member. The actuating member thereby brings the brake pad in contact with the guide rail and retracts the brake pad from the guide rail. The conversion mechanism further comprises a cam mechanism having a cam member driven to rotate by the rotational movement of the motor, wherein a driving profile of the cam member is in contact with the actuating member. The driving profile is configured to convert the rotational movement of the cam member into the linear movement of the actuating member.
