Abstract

The invention relates to a warning device for abnormal opening of an elevator floor door. The warning device comprises a shell, LED lamps, reflective stickers and a fluorophor. The shell comprises a housing and a base plate. The LED lamps are light emitting diodes and are arranged in the midpoint of the base plate. The reflective stickers are stuck to the edge of the base plate and the gaps between all the LED lamps. The fluorophor comprises a fluorescence lampshade and fluorescent powder. The whole warning device for abnormal opening of the elevator floor door is fixed to the elevator well wall directly opposite to the elevator floor door through screw holes in the base plate and is about 1.7 m distant from the floor ground. According to the technical scheme, when the elevator floor door is opened abnormally, especially when an elevator car is not at the corresponding floor, enough warning is given to a user before the user does not find the abnormal condition and enters an elevator blindly and the step missing dangerous condition appears, and the probability of elevator accidents can be lowered effectively.

Description

A kind of elevator floor door abnormal start-up alarming device

Technical field

The present invention relates to a kind of alarming device of elevator floor door abnormal opening.

Background technology

In the last few years, elevator accident occurs frequently, and after being primarily due to the unlatching of elevator floor door, lift car does not exist Correspondence floor, and user does not notice in time and causes user to fall into hoistway, and security incident occurs, elevator safety problem is Jing causes increasing people to pay attention to.

There is following safety measure on elevator floor door at present：

1. safety contact.When elevator layer is not turned off in place, its contact access failure, now elevator floor door will not startup optimization.

2. mechanical door lock.The unlatching of door lock relies on the Elevator car door operator on lift car to drive, therefore, work as elevator car Not in the floor, elevator floor door does not have power resources in railway carriage or compartment, and elevator floor door cannot be opened.

3. automatic door-closing.After elevator floor door is opened, without external force（In the case of hindering）Under effect, layer door can be certainly It is dynamic to close.

3 points based on more than, current lift product in lift car not in the floor when, theoretically elevator floor door Without power resources, and there is door lock on elevator floor door, be the situation that elevator floor door abnormal start-up impossible occur, but elevator Floor door abnormal start-up causes user to fall into the thing in hoistway still to happen occasionally, cause very big injury, casualty accident, with Upper traditional elevator safety measure does not prevent completely the generation of elevator safety accident.In order to more reliable solution elevator safety is used Problem, it is necessary to increase a kind of new abnormal elevator alarming device to make up the not comprehensive problem of existing safety measure.

The content of the invention

It is an object of the invention to provide a kind of elevator floor door abnormal start-up alarming device, during for warning floor door to open Lift car not in the abnormal conditions of respective storey, to reduce the probability of elevator safety accident generation.

Realizing the technical scheme of above-mentioned purpose is：A kind of elevator floor door abnormal start-up alarming device, comprising housing, LED Lamp, reflection plaster, fluorophor；Wherein, housing front is in equilateral triangle, and comprising shell and substrate, shell selects transparent plastic, is used for Dust in isolation air, substrate is used to lay LED, reflection plaster and printed circuit board, and on three angles of substrate spiral shell is equipped with Hole, for fixing whole alarming device；LED is Light-Emitting Diode, excellent using duration etc. with low-voltage, specular removal and height Point, LED is arranged on the centre of substrate, and welding is arranged on the printed circuit board on substrate, and constitutes exclamation mark Warning symbol, in the case of energization, the light that the LED lighted sends is in exclamation mark shape to warn user（Sedan-chair can not be entered Railway carriage or compartment）；Reflection plaster is affixed on the gap between the edge of substrate and each LED, and reflection plaster can make incident ray through three total reflections Form reflex reflection, i.e. reflection light and be extended into and penetrate radiation direction and reflect back so that this dress when extremely power failure causes LED not work Put and still have warning function；Fluorophor is made up of fluorescent lamp shade and fluorescent material, and fluorescent material is coated in the inner surface of fluorescent lamp shade, glimmering On LED, fluorescent material can absorb the light that LED sends to light lampshade in the case of energization, after LED is extinguished, then slowly Ground is discharged in the way of fluorescence, and the duration is up to a few houres to ten a few houres, remains to play under powering-off state The effect of warning；The alarming device of whole elevator floor door abnormal opening is being fixed on elevator floor door just by the screw on substrate In the hoistway wall on opposite, and 1.7 meters from floor ground or so.

More specifically, housing is in positive Mitsubishi's post shapes, and the section of triangular prism is equilateral triangle, and the length of side of triangle is 0.6 Rice, triangular prism is a height of 0.1 meter, has screw on three angles of substrate, for alarming device to be fixed on elevator floor door just In the hoistway wall on opposite, in order that user can be clearly seen that alarm signal, warning dress in elevator floor door abnormal opening Put be fixed on from floor ground it is high 1.7 meters at.

Reflection plaster is affixed on the gap between the edge of substrate and each LED, and one equilateral triangle of composition surrounds an exclamation Number shape, when the light outside elevator is incident thereon, incident light can be reflected back to warn user along former road.

Fluorophor is mainly made up of fluorescent lamp shade and fluorescent material, and fluorescent material is coated in the inner surface of fluorescent lamp shade, and smears Into the shape of equilateral triangle one exclamation mark of encirclement.

Implement the technical program to have the advantages that：The alarming device when elevator floor door is normally-open can be realized It is blocked, user can't see information warning, elevator is normally used；When elevator floor door abnormal opening, particularly work as lift car Not in respective storey, user does not have found and blindly will appear from stepping on before sky dangerous situation into elevator, can pass through apparatus of the present invention LED lamplight, one or more form of three kinds of forms of reflection plaster and fluorophor, to warn enough, can effectively reduce electricity to user The probability that terraced accident occurs.
