Definitions

  • the invention relates to an elevator component, in particular relates to an elevator car door operator device.
  • a door vane of a car side door operator In the process that an elevator runs up and down, when a car is in flush with a landing, a door vane of a car side door operator usually drives a landing door lock linkage roller on a landing door side to move together to realize the action of opening and closing an elevator door.
  • Commonly used door vanes include synchronous door vanes and asynchronous door vanes.
  • Synchronous door vanes are a kind of door vanes which firstly clamp the landing door lock linkage roller, and then the car door and the landing door move together.
  • Asynchronous door vanes move simultaneously with the car door, before the car door and the landing door move together, the car door generally has to go a certain distance, and when the door is closed, asynchronous door vanes release a driving force to the landing door in a door closing direction in advance.
  • US20170217732A1 discloses, in an elevator car door apparatus, a locking member is disposed on a blade-carrying car door, and is displaceable between an unlocked position and a locked position interdependently with movement of a doorstop-side blade.
  • a guiding portion is disposed on the locking member.
  • a guiding cam is disposed outside the blade-carrying car door.
  • the locking member displaces to the locked position
  • the doorstop-side blade also displaces to a locking acommodating position
  • the locking member catches in a fixed latch, and movement of the blade-carrying car door in the opening direction is prevented.
  • EP0763496B1 discloses, in the procedure for closing an elevator landing door, the landing door is coupled with the car door by means of a door coupler, and the car door is moved by means of an actuator provided in conjunction with the elevator car.
  • the car door and landing door are moved at the same speed, but towards the end of the closing movement the landing door is caused to move faster than the car door.
  • the coupling elements of the door coupler are moved in the direction of the car door movement.
  • FIG. 1 illustrates a state of a landing door lock under the control of a conventional door operator device. Since asynchronous door vanes will apply the pushing force to the landing door in the door closing direction in advance when the door is closed, when the closing speed of the landing door is smaller than the car door, the landing door hook will lose control and is locked prematurely, and it will collide the fixed hook of the landing door prematurely when the door is closed, which will too quickly consume the initial kinetic energy when the landing door loses control. When there is air pressure at the landing, the sliding block at the bottom of the landing door will squeeze the side wall of the sill under the air pressure, which will increase the friction force at the bottom. When the forced door closing force is smaller than the friction force, it will cause that the landing door cannot be closed normally.
  • the technical problem to be solved by the present invention is to provide an elevator car door operator device, which can prevent the landing door hook from being locked prematurely when the closing speed of the landing door is smaller than the speed of the car door.
