Abstract
The utility model discloses a monitoring and alarm device for hoistway door is opened unusually, detection switch and alarm unit are opened to car position photoelectric detection switch, room door including establishing ties in proper order at power the two poles of the earth, the alarm unit is including warning light parallelly connected mutually and buzzing siren, car position photoelectric detection switch arranges the interior normally closed state that just is of elevartor shaft in. The utility model discloses be of value to the safety protection of elevator, when elevator car not in room door position and room door is opened unusually, this device will send acousto -optic warning and remind the passenger to pay attention to, avoids the blindly walking danger of falling into the elevator well of passenger.
Description
Technical field
The utility model relates to the security technology area of vertical lift, is specifically related to a kind of monitoring for hoistway door abnormal start-up and warning device.
Background technology
At present, the closedown of hoistway door, detect by Room door lock, any one Room door or gate are not reliably closed, and elevator can not run.But elevator is in this layer when stopping scalariform state, if other Room door abnormal start-up, passenger can be caused to fall into the danger of hoistway.Current elevator does not have so a kind of automatic monitoring and the device of warning, and safety just can only lean on that passenger's oneself is careful, and maintenance intensive concentration, exists larger potential safety hazard.
Utility model content
The utility model aims to provide a kind of monitoring for hoistway door abnormal start-up and warning device, with solve existing elevator when parked other floor Room door abnormal start-ups cause personnel to fall the problem of elevator.
The utility model is achieved by following technical solution:
For monitoring and the warning device of hoistway door abnormal start-up, comprise the car position photoelectric detection switch, Room door open detection switch and the alarm unit that are connected on two poles successively, described alarm unit comprises the Warning light and buzzer alarm that are in parallel; Car position photoelectric detection switch to be placed in elevator and to be normally off.
Described Room door open detection switch comprises transmitter unit and receiving element.
The beneficial effects of the utility model are:
Compared with prior art, the monitoring for hoistway door abnormal start-up that the utility model provides and warning device are of value to the safety precaution of elevator, when the lift car not Room door abnormal start-up in door position, the Room, this device will send sound and light alarm reminding passengers and note, avoids passenger blindly to walk and falls into the danger of elevator hoistways.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is Room door open detection on-off principle figure in the utility model;
In figure: 1-car position photoelectric detection switch; 2-Room door open detection switch; 3-Warning light; 4-siren horn; 5-power supply; 6-transmitter unit; 7-receiving element.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1, the monitoring for hoistway door abnormal start-up that the utility model provides and warning device comprise the car position photoelectric detection switch 1, Room door open detection switch 2 and the alarm unit that are connected on power supply 5 the two poles of the earth successively, and described alarm unit comprises the Warning light 3 and buzzer alarm 4 that are in parallel; Car position photoelectric detection switch 1 to be placed in elevator and to be normally off.
As shown in Figure 2, described Room door open detection switch 2 comprises transmitter unit 6 and receiving element 7.
Embodiment: car position photoelectric detection switch 1 is arranged in elevator, every first floor all will arrange a car position photoelectric detection switch 1, and state is normally closed contact; The Room door of every one deck arranges Room door open detection switch 2, when lift car not certain layer of door position, the Room time, this layer of car position photoelectric detection switch 1 contact connects, if this layer of Room door open detection switch 2 monitors hoistway door and opens, the detection contacting of Room door open detection switch 2, be arranged on Warning light 3 outside this layer of Room bright, buzzer siren 4 sounds the alarm simultaneously, and reminding passengers is hoistway door beyond this point.
And when elevator car arrives layer door position, the Room time, the normally closed contact of this layer of car position photoelectric detection switch 1 disconnects, Warning light 3 and buzzer alarm 4 all can not be reported to the police.
In addition, the every one deck of this device is installed a set of, and the device of every layer is independent separately, and this device is independent of apparatus for controlling elevator, can not cause cross jamming to elevator.
