Abstract
Elevator door opens by mistake drop preventer, it is made up of the anti-falling mechanism below some layer doors each inside stair shaft and the protection network installed in stair shaft bottom, anti-falling mechanism includes rotating shaft, some infrared inductors, turnover panel and upset motor, rotating shaft both ends are fixed on stair shaft inwall, turnover panel side is connected in rotating shaft, and upset motor output shaft is connected with rotating shaft, and infrared inductor is arranged in rotating shaft, grid screen is installed on turnover panel, sets cable to perforate on grid screen.The utility model creativeness is setting anti-falling mechanism inside stair shaft below each layer door, and solving the problems, such as car, the layer door personnel of being opened do not fall in place, substantially increase lift running safety, have the advantages of reasonable in design, easy to use and safe and efficient.
Description
Technical field
It the utility model is related to lift running safety protection technology field, and in particular to a kind of elevator door opens by mistake fall arrest
System.
Background technology
Elevator is a kind of vertical conveyor using motor as power, equipped with box-like gondola, for tier building multiply 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.
Elevator industry is focused primarily upon in the fall arrest research of car to lift running safety input at present, 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 relevant enterprise is studied in this problem industry, is buried safely and is got over to elevator operations staff
Therefore hidden danger.
Utility model content
The utility model provides a kind of elevator door and opens by mistake drop preventer, is transported with solving elevator existing for prior art
The problem of administrative staff falls.
The utility model solves its technical problem institute：
A kind of elevator door opens by mistake drop preventer, by the fall arrest machine below some layer doors each inside stair shaft
Structure and the protection network composition installed in stair shaft bottom, anti-falling mechanism include rotating shaft, some infrared inductors, turnover panel and upset
Motor, rotating shaft both 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, sets cable to perforate on grid screen.
Operation principle of the present utility model：The car of elevator traction machine drive running in, each layer door of stair shaft
Infrared inductor in anti-falling mechanism senses to car, before some layer of door is opened, the anti-falling mechanism of this layer of door
If infrared inductor in senses car in place, and upset motor is not run, once layer door opens the anti-of preceding this layer of door
Infrared inductor in falling mechanism does not sense car in place, and upset motor can drive turnover panel to overturn by rotating shaft, turn over
Plate can be horizontally placed at below this layer of door, once the layer door personnel of being opened can be stepped on the grid screen of turnover panel, prevent from falling, grid
Online cable perforation is available for the retinue cable of car to pass through, and the protection network that stair shaft bottom is set can provide falling accident last
Protect together, at utmost reduce accident harm.
The utility model creativeness is setting anti-falling mechanism inside stair shaft below each layer door, solves car not in place
The problem of layer door personnel of being opened fall, substantially increases lift running safety, has reasonable in design, easy to use and safe
The advantages of efficient.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of Tthe utility model system；
Fig. 2 is the scheme of installation of the utility model anti-falling mechanism.
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.
Embodiment
As depicted in figs. 1 and 2, a kind of elevator door opens by mistake drop preventer, and each layer in the inside of stair shaft 1 is arranged on by some
The anti-falling mechanism of the lower section of door 2 and the protection network 11 installed in the bottom of stair shaft 1 form, if anti-falling mechanism includes rotating shaft 6, extra dry red wine
Outside line inductor 7, turnover panel 8 and upset motor 12, the both 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.
Operation principle of the present utility model：The car 3 of elevator is in traction machine 4 drives running, each layer door 2 of stair shaft
Anti-falling mechanism in infrared inductor car is sensed, before some layer of door is opened, the fall arrest machine of this layer of door
If the infrared inductor in structure senses car in place, upset motor is not run, once layer door opens preceding this layer of door
Infrared inductor in anti-falling mechanism does not sense car in place, and upset motor can drive turnover panel to overturn by rotating shaft,
Turnover panel can be horizontally placed at below this layer of door, once the layer door personnel of being opened can be stepped on the grid screen of turnover panel, prevent from falling, grid
Cable perforation 10 in grid is available for the retinue cable 5 of car to pass through, and the protection network that stair shaft bottom is set can carry to falling accident
Protected together for last, at utmost reduce accident harm.
The utility model creativeness is setting anti-falling mechanism inside stair shaft below each layer door, solves car not in place
The problem of layer door personnel of being opened fall, substantially increases lift running safety, has reasonable in design, easy to use and safe
The advantages of efficient.
