Description
Technical Field
The invention relates to the technical field of elevator doors, in particular to a novel elevator door system with a laterally arranged door vane.
Background
At present, most of existing elevators adopt a mounting mode of door vane device offset to reduce the gap between the car door sill and the landing door sill, so that the gap between the car door sill and the landing door sill can be reduced to the maximum extent. The area of the lift car can be further increased, and the characteristic of the originally easy-to-drop article can be realized by the means of changing the clearance of the sill; the national standard GB7588-2003 Elevator manufacturing and installation safety code 11.2.2 provides: the horizontal distance between the car sill and the landing sill is not more than 35 mm; the provision also defines that a gap is allowed between the two sills, and the general manufacturer design size is 30 mm; the elevator used in daily life can greatly reduce the gap between the car door sill and the landing door sill by the way of laterally arranging the door vane; the original 30mm is changed into 5mm, so that obviously, the hairbrush is added in the horizontal direction of the sill, the gap can be further reduced, and the effect of no gap can be achieved; however, the traditional door closing in place is realized by touching a limit switch, so that the car door and the landing door are not in the same line, and the door is not closed tightly; the anti-theft door device in the prior art is under the action of a lever, the lever proportion is limited, the multiple is small, and the false action is easy to cause; normal functions cannot be normally realized;
the traditional door closing in place is realized by touching a limit switch to retract the knife, so that the car door and the landing door are not in the same line, and the door is not closed tightly; the anti-theft door device in the prior art is under the action of a lever, the lever proportion is limited, the multiple is small, and the false action is easy to cause; normal functions cannot be normally realized; in the normal door closing process, due to the lever principle, the door body is closed in place in the process of retracting the knife after the car door knife passes through the limit switch, but the car door is completely closed in place after the knife is retracted and is reversely opened for a short distance; in the daily use process, the elevator car door is closed in place, the door lock is closed, and when the system detects that the door lock is closed, an operation instruction is sent out, so that the elevator operates; but at the moment, if the door knife is not retracted in place, the door closing moment of the door motor is kept; then the car door can continue to execute the tool retracting action; the elevator door can be opened again due to the lever effect, and the door lock is disconnected; at this moment, the elevator is easy to break down, and the normal use of the elevator is influenced.
