The current elevators are classified into synchronous door systems and asynchronous door systems according to the coordination of opening and closing of elevator hall doors and car doors. The synchronous door is a hall door and the car door is linked with a gate ball on the hall door through a gate knife on the car door, so that simultaneous opening and closing are realized. The asynchronous door is a cage door which is prior to a hall door in the opening process, in the process, a cage door motor drives a cage door plate to walk for a certain stroke in the opening process through a synchronous belt or other structural components, then an asynchronous door knife on the cage door is opened and closed (depending on whether a door ball is opened or closed through a door knife to unlock a hall door lock), and the door knife is linked with a door lock on the hall door to drive the hall door to operate.
The current asynchronous door knife is mainly realized by the contact relative movement of the door ball on the knife arm and the cam mechanism. After the new national standard is released, the door opening limiting device is required to be added, and the door opening limiting device cannot be opened by more than 50mm under the action of external force of 1000N. And the new national standard requires that the door opening limiting device of the car door can be linked with the hall door in an unlocking area. In view of the manufacturing cost, the operation stability, the installation and debugging and the maintenance, most of the existing door opening limiting devices are integrated with a door knife, and the structure mainly adds a locking hook with the function of the door opening limiting device for the door knife. .

The car door is at the end of closing, and the car door is already closed in place, and at the lock hook of the hall door, the car door is opened reversely because the external force can not fall down. In the back door opening process, the unilateral opening stroke of the car door is required to be larger than 26mm (except for the distance between the gate ball and the cutter arm, the cutter arm needs to float to unlock the door opening limiting device lock hook) so that the cutter arm lifts the lock hook under the action of the gate ball, and in the process, the hook lock is locked by the lock hook pin seat.

The implementation principle of the embodiment is as follows: in a door closing state, the left cutter arm 101 is kept open under the action of the tension spring 204, after the car door is opened, the door hanging plate drives the door cutter assembly 1 to move in the door opening process, the locking device is contacted with the roller 5012 on the double-swing-rod stroke amplifying mechanism through the stroke support 405 to generate interaction force, the acting force transmitted by the pressure spring 403 on the locking device of the double-swing-rod stroke amplifying mechanism is larger than the acting force of the tension spring 204 on the door cutter assembly 1, the force required by lifting the lock hook 3 and the hall door lock, and under the condition of the rotating resistance of the door cutter, the door cutter assembly 1 can be closed before the stroke support 405 rotates, the lock hook 3 is lifted, and if the hall door lock is lifted and blocked in the door closing process, the hall door lock is not required to be lifted again under the condition that the hall door lock hook 3 cannot fall. After the door knife assembly 1 is fully opened and closed, the locking bracket assembly 6 locks the rocker 201 under the dead weight and the force of the torsion spring 602. After that, the double swing lever travel amplifying mechanism cannot continue to rotate, the car door continues to open, the travel bracket 405 rotates against the force of the compression spring 403, the travel bracket 405 lifts until the double swing lever travel amplifying mechanism is separated from the roller 5012, and after that, the car door continues to open. The lift of the lock hook 3 is realized from the opening of the car door to the closing of the door knife assembly 1, if the lift of the lock hook 3 encounters the blocking of the hall door in the closing process, the lift of the hall door lock is 8mm in the process that the lock hook 3 can not fall down and the lift of the hall door is not needed again, the lift is far less than the horizontal meshing size of the lock hook 3 and the pin seat of the lock hook 3 by 20mm, and the blocking problem of the lock hook 3 can not occur.
In the door closing process, at the tail end of the door closing process, the roller 5012 on the double-swing-rod stroke amplifying mechanism enables the stroke bracket 405 to be lifted, the locking rod 601 is lifted under the action of the unlocking shaft 404 at the position 8mm before the door closing is in place, the door continues to be closed, and when the left inclined surface stroke of the stroke bracket 405 is finished, the stroke bracket 405 does not exert force on the double-swing-rod stroke amplifying mechanism any more, and the door knife assembly 1 automatically completes the opening action under the action of the tension spring 204. The double swing rod stroke amplifying mechanism can enable the stroke required by the car door to be 4-10mm in the process.
An asynchronous elevator door vane driving method, comprising the following steps:
S1: the first stroke of the car door opening process is that the door knife assembly 1 mounted to the door hanging plate moves away from the direction of the group lock mechanism 4, so that the roller 5012 slides or slides along the stroke bracket 405, the roller 5012 is arranged on the left circular arc of the stroke bracket 405, and in the process, the closed driving force of the door knife assembly 1 is clockwise rotation force applied to the rocker 201 by the pressure spring 403 through the stroke bracket 405, the double swing rod stroke amplifying group 5 and the second connecting rod 202. The resistance of the closure of the door knife assembly 1 is the clockwise rotation force applied to the rocker 201 by the tension spring 204, the clockwise rotation force of the hall door lock ball acting on the rocker 201 through the left floating knife arm 101 and the right floating knife arm 102, and the clockwise rotation force of the lock hook 3 acting on the rocker 201 through the left floating knife arm 101 and the right floating knife arm 102. The compression spring 403 provides the driving force for closing the door knife assembly 1 too much as the resistance force applied to the door knife assembly 1, the door knife is closed, the lock hook 3 is lifted, and the hall door lock is lifted. In this process, the stroke bracket 405 does not rotate or slightly rotates under the force of the compression spring 403.
S2: after the door vane assembly 1 is completely closed, the arc waist hole 2011 on the rocker 201 is under the limit action of the guide post 10501, the rocker 201 cannot continue to rotate clockwise by thorium, and the locking rod 601 locks the rocker 201 under the action of dead weight and the torsion spring 602, so that the rocker 201 cannot rotate anticlockwise:
S3: in the second stroke of the continuous opening of the car door, the roller 5012 is on the right arc of the stroke bracket 405, and the force transmitted to the rocker 201 by the pressure spring 403 through the stroke bracket 405, the double swing rod stroke amplifying assembly 5 and the second connecting rod 202 is a counterclockwise rotating force, but the rocker 201 cannot rotate counterclockwise under the action of the locking rod 601. After that, the travel bracket 405 rotates against the force of the compression spring 403 under the reaction of the roller 5012 on the double swing lever travel amplifying assembly 5, and the travel bracket 405 lifts until being separated from the roller 5012:
S4: the car door is closed by charter by voyage first strokes, the roller 5012 is arranged on the right circular arc of the stroke bracket 405, the stroke bracket 405 provides a counterclockwise rotating force for the double-swinging-rod stroke amplifying assembly 5 through the roller 5012 under the action of the pressure spring 403, and the swinging-rod 201 cannot rotate against thorium in time under the action of the locking rod 601. After that, the stroke bracket 405 rotates against the force of the compression spring 403 under the reaction of the roller 5012 on the double swing lever stroke amplifying assembly 5, and the stroke bracket 405 lifts.
