Using the embodiment of the present application provide a kind of elevator cab door abnormal start-up warning device, can by it is described after
Electrical equipment is engaged with the mainboard signal controlling switch, controls path or the open circuit of the warning circuit.It can realize:In elevator
When car door is normally-open, the mainboard controlling switch is not closed, and the alarm will not be alarmed;Opened in abnormal elevator
When, such as when elevator is not forced to open in layer door opening position, the of the mainboard signal controlling switch and the relay
Two contacts are closed, and the warning circuit path, the alarm is alarmed.So it is achieved that abnormal to elevator cab door
Open situation it is effective, targetedly alarm, effectively increase the security of elevator.
Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in application, for those of ordinary skill in the art, do not paying the premise of creative labor
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of circuit structure of the warning device for elevator cab door abnormal start-up that the application one embodiment provides
Schematic diagram.
Embodiment
The embodiment of the present application provides a kind of warning device of elevator cab door abnormal start-up.
In order that those skilled in the art more fully understand the technical scheme in the application, it is real below in conjunction with the application
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described implementation
Example only some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the application, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, it should all belong to the application protection
Scope.
Fig. 1 is a kind of a kind of apparatus structure of embodiment of warning device of herein described elevator cab door abnormal start-up
Figure.Although this application provides such as following embodiments or apparatus structure shown in the drawings, based on routine or without creative
Work can include more or less modular units in said device.Necessary causality is not present in logicality
Structure in, the modular structure of these devices is not limited to the embodiment of the present application or modular structure shown in the drawings.
Specifically as described in Figure 1, a kind of one kind of the warning device for elevator cab door abnormal start-up that the application provides is real
Applying example can include:
Door interlock switch 1, when the car door is opened, the door interlock switch 1 disconnects, when the car door is closed, institute
Door interlock switch 1 is stated to close;
Relay K1, input are connected in closed-loop path 101/102 with the door interlock switch 1, the relay K1 roots
Closure or the disconnection of its contact are controlled according to the state of the door interlock switch 1;
Safety return circuit 201/202, the first contact 2 of the relay K1 are connected in the safety return circuit 201/202, are used
In the path or open circuit that control the safety return circuit 201/202;Warning circuit 301/302, touched by the second of the relay K1
Point 3, alarm 5, mainboard signal controlling switch 4, the composition of emergency power supply series connection 6.
Wherein, 101/102 the circuit between 101 and 102 in figure is represented, likewise, 201/202 represents 201 and 202 in figure
Between circuit, 301/302 represents circuit between 301 and 302 in figure.
In this example, the mainboard signal controlling switch 4 is controlled by elevator-mainboard, is in and is had a power failure or not in layer in the car
During door position, the switch closure of mainboard signal control 4.
In this example, when the door interlock switch closes, the relay adhesive, first contact closure is controlled, it is described
Safety return circuit turns on.
Corresponding, in this example, when the door interlock switch disconnects, the relay disconnects, and controls first contact to break
Open, the safety return circuit open circuit.
Further, in this example, when the door interlock switch closes, the relay adhesive, second contact is controlled
Disconnect.
Corresponding, when the door interlock switch disconnects, the relay disconnects, and controls second contact closure.
Exemplary, the part work-based logic process in herein described device implementation process is as follows:
When car door is closed, the door interlock switch closure, now relay K1 adhesives, first contact is controlled to close
Close, safety return circuit conducting.When gate is opened, the door interlock switch disconnects, and relay K1 disconnects, and controls first contact to break
Open, safety return circuit, which is just opened, makes elevator stop ladder.When elevator under normal circumstances, car is not at layer door position, or elevator is in
Power down mode, the mainboard signal controlling switch can all be connected.
Therefore, elevator is not at layer door, and when gate is pushed aside, relay K1 can not obtain electric, second contact closure, main
Partitioned signal is connected, and the alarm powered by emergency power supply 6, alarmed, and plays warning function, reminds in sedan-chair personnel should not be with
Just gate is pushed aside, dangerous to prevent producing, until gate closing or Elevator landing, alarm just can stop alarm.
Each embodiment in this specification is described by the way of progressive, same or analogous portion between each embodiment
Divide mutually referring to what each embodiment stressed is the difference with other embodiment.
Although depicting the application by embodiment, it will be appreciated by the skilled addressee that the application have it is many deformation and
Change is without departing from spirit herein, it is desirable to which appended claim includes these deformations and changed without departing from the application's
Spirit.
