ELEVATOR SAFETY DEVICE AND ELEVATOR SAFETY DEVICE MOUNTING METHOD

摘要

A safety device main body that is inserted inside a lower frame of a car frame includes a braking member. A guiding apparatus includes a guide shoe that is displaceable inside the safety device main body between a guided position that is guided by a guide rail and a retracted position that is removed from the guided position. The guide shoe is disposed in the guided position when the braking member is separated from the guide rail. An actuating apparatus displaces the guide shoe toward the retracted position while displacing the braking member in a direction of contact with the guide rail. The safety device main body, the guiding apparatus, and the actuating apparatus are supported together by a supporting body. The supporting body is mounted onto the lower frame from below using a mounting aperture that is previously disposed on the lower frame.

主权项

1. An elevator safety device that is mounted onto a car that comprises a cage and a car frame that surrounds the cage, the car being moved along a guide rail, and the elevator safety device applying a braking force to the car,
wherein the elevator safety device comprises: a safety device main body that includes a braking member that can contact with and separate from the guide rail, and that is inserted inside a lower frame of the car frame so as to apply a braking force to the car by placing the braking member in contact with the guide rail; a guiding apparatus that includes a guide shoe that is displaceable inside the safety device main body between a guided position that is guided by the guide rail and a retracted position that is removed from the guided position, the guide shoe being disposed in the guided position when the braking member is separated from the guide rail; an actuating apparatus that displaces the guide shoe toward the retracted position while displacing the braking member in a direction of contact with the guide rail; and a supporting body that is mounted onto the lower frame from below using a mounting aperture that is previously disposed on the lower frame so as to support the safety device main body, the guiding apparatus, and the actuating apparatus together.
