Elevator door vane Hitachi C0045591-B elevator Car door attachment device parts

The elevator door knife is mainly responsible for opening and closing the elevator hall car door. When it receives the elevator door opening and closing signals, the elevator door machine controls the door opening motor through its own control system, converting the torque generated by the motor into a force in a specific direction, thereby closing or opening the door.

The elevator door knife is generally composed of a door knife frame, a door knife arm, a blade, a telescopic rod, a connector, etc. Among them, the door knife frame is the base of the entire door knife system, and the door knife arm and the blade are installed on the door knife frame; the telescopic rod is used to adjust the length of the door knife to adapt to elevator doors of different sizes; the connector is used to connect the door knife to the guide rail of the elevator.

The working principle of the elevator door knife involves the entire operating system of the elevator. The two ends of the elevator traction rope are connected to the car and counterweight respectively, and are wound on the traction wheel and guide wheel. The traction motor drives the traction wheel to rotate after the speed is changed by the reducer, and the traction force generated by the friction between the traction rope and the traction wheel is used to realize the lifting and lowering movement of the car and the counterweight. The elevator door knife is installed on the elevator car door to drive the hall door and realize the synchronous movement of the hall door and the car door.
