Abstract

An elevator safety door can play a role of safety protection when an elevator landing door is opened by mistake. The safety door is arranged between the elevator landing door and a car door. The safety door is clamped between guide rails at the upper end and the lower end and can slide along the guide rails, and both the guide rails are fixed to a wall. Opening and closing of the landing door and opening and closing of the safety door do not affect each other. One-way synchronous movers are arranged at corresponding positions of the safety door and the car door and guarantee that the safety door does not affect normal vertical movement of an elevator car, and when the car moves to the position in front of the safety door, the car door can be normally opened and closed, and the safety door and the car door can be synchronously opened and closed.

Description

A kind of elevator safety door

Technical field

Patent of the present invention relates to elevator protection device field, is specially a kind of elevator safety door.

Background technology

Elevator is as the personnel of transport and the instrument of goods; although have employed a series of safety precautions; the accident of the casualties caused because of control system fault, door system fault still can occur; such as; news is repeatedly reported and is not arrived due to lift car and hall door opens by mistake, and people is strayed into and the event of the elevator that falls.

The utility model patent of Application No. 201420616809.2 discloses a kind of elevator and opens by mistake the protection device of door, and its structure includes motor, the red labyrinth such as warning lamp and buzzer, relatively costly, uses more complicated.

Summary of the invention

For solving the problem proposed in above-mentioned background technology, patent of the present invention provides a kind of elevator safety door, manufacture, use cost low, and eliminate hall door and open by mistake the danger of initiation.

The technical scheme of patent of the present invention is: safety door together with arranging between hoistway door with car door；Safety door card is between the guide rail at upper and lower two ends, it is possible to along slide, and guide rail is all fixed on wall；The switch of hall door is independent of each other with the switch of safety door；Safety door is equipped with one-way synchronization shifter with the corresponding positions of car door, one-way synchronization shifter ensures that safety door does not affect lift car and normally moves up and down, and when car moves to before safety door, car door can be with normal switch, safety door and car door synchro switch.Each layer of elevator all can decide whether to install safety door as required.

Preferably, one-way synchronization shifter is made up of the jut on the reeded protruding parts of safety door band and car door, and the jut on car door can slide up and down in the groove of the reeded protruding parts of safety door band, it is impossible to moves left and right in groove.

Preferably, one-way synchronization shifter is made up of the jut on the reeded protruding parts of car door band and safety door.

Preferably, narrow between the groove two ends alleviating distention in middle-JIAO of the reeded protruding parts of safety door band, jut two ends on car door point, facilitate the jut on car door to come in and go out the groove of the reeded protruding parts of safety door band.

Preferably, the groove of the reeded protruding parts of safety door band is relative arc, jut two ends on car door point, facilitates the jut on car door to come in and go out the groove of the reeded protruding parts of safety door band.

Preferably, safety door is plain batton door.

Preferably, safety door is made up of doorframe and doorframe inner structure, and doorframe inner structure can be latticed, paliform, hole shape or other structure, and the reeded protruding parts of safety door band is on doorframe.

Preferably, safety door housing is fixed, and inside casing can be along slide；Between housing and inside casing, part can deform upon with the movement of inside casing, it is achieved the normal switch of safety door；The reeded protruding parts of safety door band is on inside casing.This structure can reduce the guide rail of about half length, had both saved space, and had reduced again cost.

Preferably, safety door housing can be fixed on wall or be fixed on guide rail.

Preferably, between safety door housing and inside casing, part is the some ropes being simultaneously connected on housing and inside casing, and when safety door is opened, rope hangs down due to self gravitation, and when safety door is closed, rope is straightened.

Preferably, between safety door housing and inside casing, part is some poles, and pole two ends hinge respectively, can be with free folding in the middle of pole on inside casing and housing.

Preferably, safety door can be univalve door.

The invention has the beneficial effects as follows, independent of elevator general control system, remain to play a protective role when the system failure, and manufacture, use cost low.
