Abstract
The invention discloses an elevator landing door by-mistake opening fall-preventing system which is composed of a plurality of fall-preventing mechanisms mounted in a stair shaft and below all landing doors and a protective net mounted at the bottom of the stair shaft, wherein each of the fall-preventing mechanisms comprises a rotary shaft, a plurality of infrared ray sensors, a turning plate and a turnover motor; two ends of the rotary shaft are fixed on the inner walls of the stair shaft; one side of the turning plate is connected onto the rotary shaft; the output shaft of the turnover motor is connected with the rotary shaft; the infrared ray sensors are arranged on the rotary shaft; a grid net is mounted on the turning plate; and a cable through hole is formed in the grid net. According to the invention, the fall-preventing mechanisms are creatively arranged below each landing door and in the stair shaft, so that the problem that the landing door is opened while a lift car is not in place to cause falling of a passenger is solved, the operating safety of an elevator is greatly improved, and the elevator landing door by-mistake opening fall-preventing system has the advantages of reasonable design, high convenience in using and high safety and efficiency.
Description
Technical field
The present invention relates to lift running safety protection technology field, and in particular to a kind of elevator door opens by mistake fall arrest system
System.
Background technology
Elevator is a kind of vertical conveyor with motor as power, equipped with box like gondola, for tier building take advantage of people or
Carrying goods.With constantly building up for skyscraper, elevator is used widely as vertical transportation means of transport in building,
The use of elevator also brings larger security risk.
At present elevator industry is focused primarily upon in the fall arrest research of car to lift running safety input, ignores personnel
Problem of falling in stair shaft, such as, when car does not reach layer door position, layer door is opened, and people occurs once personnel enter into
Member's falling accident, never has relevant enterprise and is studied in this problem industry, bury safely to elevator operations staff and get over
Therefore hidden danger.
The content of the invention
The invention provides a kind of elevator door opens by mistake drop preventer, to solve the elevator operation people of prior art presence
The problem that member falls.
The present invention solves its technical problem：
A kind of elevator door opens by mistake drop preventer, by some fall arrest machines below each layer of door in stair shaft inside
Structure and the protection network installed in stair shaft bottom are constituted, and anti-falling mechanism includes rotating shaft, some infrared inductors, turnover panel and upset
Motor, rotating shaft two ends are fixed on stair shaft inwall, and turnover panel side is connected in rotating shaft, and upset motor output shaft is connected with rotating shaft,
Infrared inductor is arranged in rotating shaft, and grid screen is installed on turnover panel, and cable perforation is arranged on grid screen.
The operation principle of the present invention：The car of elevator traction machine drive running in, each layer of door of stair shaft it is anti-fall
The infrared inductor fallen in mechanism senses to car, before certain layer of door is opened, in the anti-falling mechanism of this layer of door
If infrared inductor senses car in place, upset motor is not run, once layer door opens the fall arrest of front this layer of door
Infrared inductor in mechanism does not sense car in place, and upset motor can drive turnover panel upset, turnover panel meeting by rotating shaft
This layer of door lower section is horizontally placed at, personnel just can be stepped on the grid screen of turnover panel once layer door is opened, and prevent from falling, on grid screen
Cable perforation be available for the retinue cable of car to pass through, the protection network that stair shaft bottom is arranged falling accident can be provided it is last together
Protection, at utmost reduces accident harm.
The invention arranges anti-falling mechanism below each layer of door inside stair shaft, solves car not layer door in place
The problem that the personnel of being opened fall, substantially increases lift running safety, with reasonable in design, easy to use and safe and efficient
Advantage.
Description of the drawings
With reference to the accompanying drawings and examples the present invention is further described.
Fig. 1 is the structural representation of present system；
Fig. 2 is the scheme of installation of anti-falling mechanism of the present invention.
1 stair shaft, 2 layers of door, 3 cars, 4 traction machines, 5 retinue cables, 6 rotating shafts, 7 infrared inductors, 8 turnover panels, 9 grid in figure
Grid, the perforation of 10 cables, 11 protection networks, 12 upset motors.
Specific embodiment
As depicted in figs. 1 and 2, a kind of elevator door opens by mistake drop preventer, by some installed in each layer of the inside of stair shaft 1
The anti-falling mechanism and the protection network 11 installed in the bottom of stair shaft 1 of the lower section of door 2 is constituted, if anti-falling mechanism includes rotating shaft 6, extra dry red wine
Outside line induction apparatuss 7, turnover panel 8 and upset motor 12, the two ends of rotating shaft 6 are fixed on the inwall of stair shaft 1, and the side of turnover panel 8 is connected to rotating shaft 6
On, the output shaft of upset motor 12 is connected with rotating shaft 6, and infrared inductor 7 is arranged in rotating shaft 6, and grid screen 9 is installed on turnover panel 8,
Cable perforation 10 is set on grid screen 9.
The operation principle of the present invention：The car 3 of elevator drives in running in traction machine 4, each layer of door of stair shaft 2 it is anti-
Infrared inductor in falling mechanism senses to car, before certain layer of door is opened, in the anti-falling mechanism of this layer of door
If infrared inductor sense car in place, upset motor is not run, once before layer door is opened this layer of door it is anti-fall
The infrared inductor in mechanism that falls does not sense car in place, and upset motor can drive turnover panel upset, turnover panel by rotating shaft
This layer of door lower section can be horizontally placed at, personnel just can be stepped on the grid screen of turnover panel once layer door is opened, and prevent from falling, grid screen
On cable perforation 10 be available for the retinue cable 5 of car to pass through, the protection network that stair shaft bottom is arranged can be provided most falling accident
Protect together afterwards, at utmost reduce accident harm.
The invention arranges anti-falling mechanism below each layer of door inside stair shaft, solves car not layer door in place
The problem that the personnel of being opened fall, substantially increases lift running safety, with reasonable in design, easy to use and safe and efficient
Advantage.
