Description

Synchronous door vane and elevator

Technical Field

The invention relates to the technical field of elevator equipment, in particular to a synchronous door vane and an elevator.

Background

As a means of transportation for transporting passengers, there are two movement modes, i.e., vertical movement of a car and horizontal movement of a door system. At present, door knife components on a door machine device of a door system are mostly synchronous door knives, the synchronous door knives are a device which enables a hall car door to be linked and synchronously opened and closed, and the door system using the synchronous door knives, the door knives on the door machine device and a door lock on a landing door device are in a coupling relation, namely when an elevator door system is opened, the door knives act to enable left and right knife arms of the door knives to clamp a door ball on the door lock and then the door can be opened; when the elevator needs to move vertically to a designated floor, the door vane acts to enable the left and right knife arms of the door vane to be separated from the door ball and then to walk (walking refers to the up-and-down movement of the elevator along the vertical direction), so that the vertical movement of the elevator and the horizontal movement of the door system are required to be separated by the coupling relation of the door vane and the door lock, namely, the other movement can be executed after one movement is finished, and the two movements cannot be executed simultaneously to reduce the operation time, so that the operation efficiency of the elevator is low, the waiting time of passengers is long, and the riding experience of the passengers is seriously influenced.

Disclosure of Invention

1. Technical problem to be solved by the invention

The invention provides a synchronous door vane and an elevator, aiming at the technical problem of low operation efficiency of the elevator door system using the synchronous door vane at present, and the synchronous door vane and the elevator can improve the operation efficiency of the elevator and reduce the waiting time of passengers taking the elevator.

2. Technical scheme

In order to solve the problems, the technical scheme provided by the invention is as follows:

a synchronized door vane comprising: the door knife bottom plate is arranged on a car door machine; the knife arm assembly comprises a first knife arm, a second knife arm, a first connecting rod and a second connecting rod, the middle parts of the first connecting rod and the second connecting rod are hinged with the door knife bottom plate, two ends of the first connecting rod and the second connecting rod are respectively hinged with the first knife arm and the second knife arm, the first knife arm, the second knife arm, the first connecting rod and the second connecting rod jointly form a parallelogram mechanism with variable intervals, and the minimum interval L between the first knife arm and the second knife arm is larger than the diameter D of a layer door ball; the door knife transmission assembly is arranged on the door knife bottom plate in a sliding mode, the door knife transmission assembly is connected with the knife arm assembly, and the door knife transmission assembly is used for driving the knife arm assembly to rotate.

In the invention, because the minimum distance L between the first cutter arm and the second cutter arm is larger than the diameter D of the layer gate ball, when the synchronous gate cutter is in a cutter retracting (cutter arm folding) state, a certain gap value A is reserved between the first cutter arm and the layer gate ball and between the second cutter arm and the layer gate ball, the layer gate ball is allowed to run in the vertical direction between the first cutter arm and the second cutter arm in the process of clamping the layer gate ball by the first cutter arm and the second cutter arm due to the existence of the gap value A, and the movement mode is that the gate ball rolls along the end faces of the first cutter arm and the second cutter arm. Before the elevator vertically moves to a specified floor, the elevator still walks, but the first knife arm and the second knife arm reach the area where the gate ball is located, at the moment, the door system meets the condition of opening the door, the synchronous gate knife can execute a knife retracting action, the gate knife transmission assembly drives the knife arm assembly to do anticlockwise rotation motion by controlling the motion of the gate knife transmission assembly on the bottom plate of the gate knife, the distance between the first knife arm and the second knife arm is reduced from large to small, namely the first knife arm and the second knife arm move from an open state to a closed state, finally the first knife arm and the second knife arm clamp the layer door ball, after the synchronous gate knife retracts, the first knife arm and the second knife arm clamp the layer door ball, along with the continuous motion of the elevator in the vertical direction, the layer door ball rolls along the end surfaces of the first knife arm and the second knife arm, and meanwhile, the door system moves in the horizontal direction and opens the layer car door; when the elevator stops at a designated floor, namely a landing zone, the door system has opened the hall car doors a distance synchronously; on the contrary, before the elevator door system moves horizontally to the door closing position (the door plates of the landing door and the car door are closed), the elevator door is still closed, at the moment, the door system meets the condition of going away the elevator, the synchronous door knife can execute the knife opening action, the door knife transmission component drives the knife arm component to rotate clockwise by controlling the movement of the door knife transmission component on the door knife bottom plate, the distance between the first knife arm and the second knife arm is increased from small to large, namely the first knife arm and the second knife arm move from the folding state to the unfolding state, the synchronous door knife is before the knife opening, and the first knife arm and the second knife arm still clamp the landing door ball, the landing door ball can roll along the end surfaces of the first knife arm and the second knife arm, and the elevator also moves up and down along the vertical direction; when the elevator door system is fully closed in place, the elevator car has traveled a distance in the vertical direction (i.e., the elevator car has traveled up and down before the elevator door system is closed in place).
