Abstract
The invention relates to an elevator hoistway security gate which comprises a door frame and a door leaf, wherein the periphery of the door frame is provided with connectors which can be fixedly connected with a hoistway frame. The elevator hoistway security gate further comprises a triangular key lock and a contact switch which are arranged on the door frame. The contact switch comprises a first contact head and a second contact head which are respectively fixed on the side of the door frame and the side of the door leaf. When the elevator hoistway security gate is closed, the first contact head contacts with the second contact head; a safe loop is formed with an elevator operation circuit; and the elevator operates normally. When the elevator hoistway security gate is open, the first contact head is disengaged from the second contact head; the elevator operation circuit is switched off; and operation of the elevator is stopped. According to the elevator hoistway security gate, the triangular key lock which is specialized for the elevator is used. Not only is mis-opening of a common key prevented, but also difficulty in management of an elevator key is reduced. On the other hand, a direct door lock contact is used, thereby preventing a misoperation when the elevator hoistway security gate is open and realizing a relatively high safety performance.
