Abstract
The utility model discloses an alarm system for abnormal opening of an elevator landing door, wherein a landing door lock safety contact in each alarm circuit branch is connected with a normally-closed-type travel switch in series, and connected with an alarm lamp and an alarm bell in series. The alarm lamp and the alarm bell are in parallel connection. The alarm system is capable of reminding passengers whether the elevator landing door is in a normal state. Particularly, when a car is located at a leveling position, namely the car is located on a current floor, the travel switch is collided by a final limit cam, and the contact of the travel switch is opened. At the time, the alarm circuit branch of the current floor is powered down, and whether the landing door of the current floor is opened or not, an alarm is not given out by the alarm system of the current floor. At the time, when a landing door of another floor is abnormally opened, the landing door lock safety contact of the floor is closed, and the alarm circuit branch of the floor is powered up and alarms so as to warn that the landing door of the floor is abnormally opened and warn the passengers on the floor to be far away from the elevator. Occurrences of miserable incidents similar to the recent accident that a passenger falls into a well due to the fact that a landing door is opened when a car of an elevator does not reach a floor are effectively avoided.
Description
Technical field
The utility model relates to lift layer door irregular and opens warning.
Background technology
In the recent period, elevator accident frequent occurrence, accident occurrence cause all are because after the unlatching of layer door, lift car is not opened floor at layer door, causes the passenger to fall into hoistway.The elevator safety problem has caused more and more people's attention.
Following safety measure is arranged on the elevator door at present:
1. safety contact.The elevator layer is not closed when putting in place, its contact access failure, and this moment, elevator can not start operation.
2. mechanical door lock.The door machine that the unlatching of door lock relies on the lift car drives, and therefore, when lift car during not at this floor, layer door do not have power resources.And being in hoistway when outside, elevator door can't be opened.
3. automatic door-closing.Behind the elevator door opening, do not having under external force (in the situation about the namely hindering) effect, layer door can autoshutdown.
Based on above 3 points, with regard to present lift product, no matter be from standard, or from the structure of elevator itself, during not at this floor, be that elevator door does not have power resources at lift car in theory, and door lock is arranged on the elevator door, is the situation of impossible the genetic horizon door opening.
Just because of this, so the warning device of also not opening for lift layer door irregular on the elevator.
But actual conditions are that such thing (lift layer door irregular is opened and caused the passenger to fall in the hoistway) is exactly to have occured, and causes very large injury, injures and deaths.
Summary of the invention
The purpose of this utility model provides the warning that the monitoring lift layer door irregular is opened, and this warning is independent of existing elevator safety loop, can monitor and judge that whether car was at this floor when layer door opened.If at this floor, then warning is not reported to the police; If car was not at this floor when layer door opened, then warning can be reported to the police by alarm lamp, emergency alarm bell, thereby prompting and prevention passenger enter.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lift layer door irregular is opened warning, comprise a plurality of warning branch roads that are in parallel, be connected to the power supply at described warning branch road two ends, be equipped with on the door machine of lift car and hit bow, the corresponding one deck elevator door of each described warning branch road, described warning branch road comprise on the control panel that is installed in the respective layer door can be when this layer door be opened the layer door lock safety contact of closure, be installed on the control panel of respective layer door and can be when lift car is positioned at level position be collided the closed type travel switch that contact then disconnects by the described bow that hits, be installed in respective layer outdoors face and the alarm lamp that is in parallel and emergency alarm bell, be in series at layer door lock safety contact and described closed type travel switch described in each described warning branch road, and also be in series with the alarm lamp that is in parallel and emergency alarm bell.
During implementation, near the building wall that described alarm lamp and emergency alarm bell are installed on the landing door jamb or layer door is.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages: this warning, can whether be in normal condition by reminding passengers layer door, specifically, when car is positioned at level position (car is in current floor), then travel switch is hit the bow collision, the contact of travel switch disconnects, this moment, the warning branch road of current floor cut off the power supply, and no matter whether current floor layer door is opened, and the warning of current floor is not all reported to the police; If this moment, the layer door of other floors opened, the layer door lock safety contact of this layer can be closed, the rood electric alarm is propped up in the i.e. warning of this layer, to warn this floor layer door abnormal start-up, warn the passenger of this layer away from elevator, the car of effectively avoiding similar nearest generation not arrival floor and layer door is opened and is caused the passenger to fall into tragic event in the hoistway.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is schematic circuit diagram of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of lift layer door irregular is opened warning, comprise a plurality of warning branch roads 6 that are in parallel, be connected to the power supply at warning branch road 6 two ends, each warning branch road 6 corresponding one deck elevator door, be equipped with on the door machine of lift car and hit bow 2, each warning branch road 6 includes a secondary layer door lock safety contact 1, closed type travel switch 3, the alarm lamp 4 that is in parallel and emergency alarm bell 5, layer door lock safety contact 1 and closed type travel switch 3 are installed on the control panel of respective layer door, alarm lamp 4 and emergency alarm bell 5 are installed in the outside of respective layer door, as be installed on the landing door jamb or layer door near building wall on.Be in series with closed type travel switch 3 at each warning branch road 6 middle level door lock safety contact 1, and also be in series with the alarm lamp 4 that is in parallel and emergency alarm bell 5.
Newly-increased layer door lock safety contact 1, when layer door opened, can be closed, otherwise disconnect.Closed type travel switch 3 collides back contact and can disconnect being hit bow 2, otherwise closed.
When car is positioned at level position (car is in current floor), then travel switch 3 is hit bow 2 collisions, and the contact of travel switch 3 disconnects, at this moment warning branch road 6 outages of current floor, no matter whether current floor layer door is opened, and the warning of current floor is not all reported to the police; If this moment, the layer door of other floors opened, the layer door lock safety contact 1 of this layer can be closed, and namely the warning branch road 6 of this layer gets electric alarm, with the passenger that warns this layer away from elevator.
Whether this warning can be in normal condition by reminding passengers layer door, and the car of effectively avoiding similar nearest generation not arrival floor and layer door is opened and caused the passenger to fall into tragic event in the hoistway.
