Abstract
The utility model provides a prevent elevator that staggered floor opened door, including infrared light emitting diode and the infrared receiving terminal of setting in the elevartor shaft, the last reflector that is provided with of elevator car, when elevator operation targets in place, reflector reflection infrared light emitting diode's light to infrared receiving terminal, the anodal of infrared light emitting diode is connected with positive, and infrared light emitting diode's negative pole and power negative pole are connected, and infrared receiving terminal's power supply anode and positive are connected, and infrared receiving terminal's power supply negative terminal and power negative pole are connected. The utility model discloses opening of lift -cabin door can be avoided when the elevator staggered floor, personnel's safety is guaranteed.
Description
Technical field
The utility model relates to elevator technology field, particularly relates to a kind of elevator preventing staggered floor from opening the door.
Background technology
Elevator generally has PLC to control, and elevator interior has the mechanism preventing staggered floor from opening the door, and being generally by judging whether this one deck, if arrived, just can opening elevator door, ensures safety.But or elevator can be there is not to this one deck, door but opens, thus causes safety misadventure.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of elevator preventing staggered floor from opening the door, and solves the problem that elevator staggered floor opens the door.
The utility model is achieved in that a kind of elevator preventing staggered floor from opening the door, comprise and be arranged on infrarede emitting diode in elevator and infrared receiving terminal, lift car is provided with light deflector, when elevator runs and puts in place, the light of mirror reflection infrarede emitting diode is to infrared receiving terminal, the positive pole of infrarede emitting diode is connected with positive source, the negative pole of infrarede emitting diode is connected with power cathode, the power supply anode of infrared receiving terminal is connected with positive source, the power supply negative terminal of infrared receiving terminal is connected with power cathode, the mouth of infrared receiving terminal is connected with the electrode input end of optocoupler, the negative input of optocoupler is connected with power cathode, enabling driving circuit is connected with enabling motor by the mouth of optocoupler.
The utility model tool has the following advantages: can avoid opening of elevator door when elevator staggered floor, ensures the safety of personnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model circuit diagram.
Detailed description of the invention
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of elevator preventing staggered floor from opening the door, comprise and be arranged on infrarede emitting diode 2 in elevator 1 and infrared receiving terminal 3, lift car 4 is provided with light deflector 5, when elevator runs and puts in place, the light of mirror reflection infrarede emitting diode is to infrared receiving terminal.As shown in Figure 2, the positive pole of infrarede emitting diode D1 is connected with positive source, the negative pole of infrarede emitting diode is connected with power cathode, the power supply anode of infrared receiving terminal U1 is connected with positive source, the power supply negative terminal of infrared receiving terminal is connected with power cathode, the mouth of infrared receiving terminal is connected with the electrode input end of optocoupler RL1, and the negative input of optocoupler is connected with power cathode, and enabling driving circuit is connected with enabling motor M G1 by the mouth of optocoupler.
Wherein, when elevator cage operation is to perch, then light deflector can by the light reflection of infrarede emitting diode on infrared receiving terminal, infrared receiving terminal receives light, mouth exports high level, make the luminous conducting of optocoupler, the enabling driving circuit of elevator can driven enabling machine operation, and elevator door can be opened.And lift car do not run put in place time, light deflector can not by the light reflection of infrarede emitting diode on infrared receiving terminal, infrared receiving terminal can not receive light, mouth output low level, optocoupler is not luminous is off condition, the enabling driving circuit of elevator cannot drive enabling machine operation, and elevator door can not be opened, and ensures safety.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
