Background
In order to improve the space utilization rate of cities, high-rise buildings are increasingly used as places for work and life of people; the elevator is used as a vertical transportation tool and is closer to the traveling life of people. However, as the building height increases, a chimney effect occurs in the elevator hoistway, i.e., air flows are generated inside and outside the hoistway due to meteorological factors such as temperature and air pressure inside and outside the hoistway. This effect causes the pressure experienced by the two sides of the hall door to be different, increasing the resistance to the closing of the hall door. Asynchronous door sword is closing the door in-process, along with sedan-chair door sword is pushing layer door croquet motion, and before layer door closes completely and triggers door switching signal, sedan-chair door sword can break away from layer door croquet gradually, and sedan-chair door sword disappears to the thrust on layer door, and layer door only relies on inertia and the gravity action pulling both sides layer door closure of the weight of self.
However, under the influence of the chimney effect of the hoistway of the high-rise building, the door closing resistance of the landing door is increased, and at the tail end of the door closing action stroke, the landing door cannot be closed reliably only by means of inertia and the gravity action of a landing door heavy hammer.
Although the weight of the landing door weight can be increased or other auxiliary door closing devices are added on the side of the landing door to ensure that the landing door is reliably and completely closed, the door closing driving force is only strengthened, and the burden of a motor for opening the door or the impact of opening and closing the door can be increased when the door is opened or the situation without the chimney effect is avoided, so that the passenger experience is influenced.
Common asynchronous door sword door closing process is shown in figure 1, and sedan-chair door sword is closing the door in the process middle stage, and movable door sword can slowly open, and the layer door relies on layer door weight and inertia to close the door this moment, and when chimney effect or the too big scheduling problem of layer door running friction appear, the abnormal condition in lower right corner can appear in layer door side door ball, and the movable door sword side in door ball deviation left side leads to unable locking, elevator operation trouble.

when the car door machine drives the car door to be completely closed, the car door machine drives the driving arm (7) to rotate anticlockwise to the maximum angle around the fixed shaft 72, the spring assembly (5) contracts and pulls the main door knife (2) to enable the main upper door knife arm (3) and the main lower door knife arm (4) to rotate anticlockwise upwards, the main lower door knife arm (4) is blocked by the driving stop block (6) fixed on the upper side surface of the fan-shaped head of the driving arm (7) to stop at a required position, and the distance between the main door knife (2) and the auxiliary door knife (1) is kept at a set door opening distance; the head end of the unlocking stop block (8) is extruded on the front side surface of the baffle of the spring pin (9) to enable the spring pin (9) to move backwards along the pin hole (101) of the door knife bottom plate (10), the pin head (93) of the spring pin (9) is separated from the fixing groove (41) on the rear side surface of the main lower door knife arm (4), and the spiral spring (92) between the door knife bottom plate (10) and the baffle (91) is compressed and deformed;
when the car door machine drives the car door to be opened from a complete state and simultaneously drives the driving arm (7) to rotate clockwise around the fixed shaft, the driving stop block (6) on the driving arm (7) pushes the main lower door knife arm (4) to rotate clockwise, and the main lower door knife arm (4) drives the main door knife (2) to rotate clockwise and downwards to be folded with the auxiliary door knife (1); along with the clockwise rotation of the driving arm (7) around the fixed shaft 72, the head end of the unlocking stop block (8) moves downwards to be separated from the baffle of the spring pin (9), the deformation force of the spiral spring (92) enables the spring pin (9) to move forwards to enable the pin head (93) to move forwards and to be inserted into a fixed groove (41) formed in the rear side face of the main lower door knife arm (4), the main lower door knife arm (4) is limited to move continuously, meanwhile, the movement of the main door knife (2) is limited, the door opening state is achieved, and the spring assembly (5) is in a stretching state;
when the car door machine drives the car door to be closed from a door opening state and simultaneously drives the driving arm (7) to rotate anticlockwise around the fixed shaft 72, when the unlocking stop block (8) on the driving arm (7) moves upwards to enable the head end to be in contact with and extrude the front side of the baffle (91) of the spring pin (9), the main lower door knife arm (4) starts to be unlocked, along with the anticlockwise rotation of the driving arm (7), the front side inclined surface of the head end of the unlocking stop block (8) extrudes the baffle (91) of the spring pin (9) to enable the spring pin (9) to gradually move backwards until the unlocking stop block (8) moves to be in contact with the main lower door knife arm (4), the spring pin (9) moves backwards for the maximum distance, the pin head (93) of the spring pin (9) is separated from the fixed groove (41) on the rear side surface of the main lower door knife arm (4), the displacement limitation on the main lower door knife arm (4) is released, and the main lower door knife arm (4) is under the tension action of the spring assembly (5) on the main door knife (2), the door vane rotates anticlockwise to enable the main door vane (2) to be far away from the auxiliary door vane (1);
when the main lower door knife arm (4) rotates anticlockwise and touches the driving stop block (6), the driving stop block (6) can limit the continuous displacement of the main lower door knife arm (4); when the car door machine drives the driving arm (7) to rotate anticlockwise to the maximum angle around the fixed shaft 72, the main lower door knife arm (4) stops rotating, and the car door is completely closed.
3. The elevator vane device of claim 1,
the pin hole (101) arranged at the lower part of the door vane bottom plate (10) is a non-circular hole.
4. The elevator vane device of claim 1,
the pin holes (101) arranged at the lower part of the door knife bottom plate (10) are n-shaped holes, □ -shaped holes or delta-shaped holes.
5. The elevator vane device of claim 1,
the tail end of the pin column (94) of the spring pin (9) is fixedly provided with an anti-slip rod (95).
6. The elevator vane device of claim 1,
the slave door vane (1) is fixed relative to the door vane bottom plate (10).
7. The elevator vane device of claim 1,
the slave door vane (1) can move relative to the door vane bottom plate (10).
8. The elevator vane device of claim 1,
the spring assembly (5) is positioned between the main upper door knife arm (3) and the main lower door knife arm (4).
9. The elevator vane device of claim 1,
the upper side of the end part of the pin head (93) of the spring pin (9) is provided with a chamfer.
10. The elevator vane device of claim 1,
a chute (42) which becomes deeper from front to back is formed on the lower side of the main lower door knife arm (4) corresponding to the fixing groove (41).
