Description
Technical field：
The utility model is related to a kind of electric anti-reverse-rotation device of staircase monochromatic light, belongs to staircase security appliance field.
Background technology：
Staircase during up if when step chains fracture, main frame displacement, serious overload, can reverse fortune suddenly
OK, personal injury can be caused to passenger.Detected whether more than present staircase using mechanical or two dephased photoelectricity
Reverse and occur.Occur once reversing, service brake can be triggered and additional brake carries out brake hard, it is ensured that passenger safety.
But this method must can be detected after staircase takes a turn for the worse, and how testing result is drawn in advance, be this patent
Realize content.
The content of the invention：
In order to solve the above technical problems, the electric anti-reverse-rotation device of the staircase monochromatic light that is related to of the utility model, including one double
The optoelectronic detecting device for being used for detecting the duplex chain wheel gear teeth, the optoelectronic detecting device connection are provided with the right side of sprocket wheel, duplex chain wheel
There is main control computer, main control computer is connected to service brake and additional brake, and main control computer shows photosignal pulse.
Further, the quantity of the optoelectronic detecting device is one, relatively conventional mechanical and phase-difference type photoelectricity
Detection, saves cost.
Further, the photosignal pulse includes normal burst, reverses pulse and pulse spacing, and it is driven in the wrong direction in staircase
It is preceding just to show reverse pulse in advance, it can timely and effectively prevent staircase from driving in the wrong direction.
Optoelectronic detecting device detects duplex chain wheel tooth tip, often crosses a tooth, forms a high level, staircase is with normal speed
During normal operation, photoelectricity will form regular impulse wave, and the pulse is introduced into main control computer, and main control computer is in uplink state
Timing is carried out to photoelectric pulse wave rising edge interval during high level.When will appear from reversing during staircase is up, duplex chain wheel
Speed slows down first, then stops, and finally reverses, and at this moment photoelectricity waveform is reverses pulse, and main control computer detects photoimpact
Rising edge interval time will become big, can determine that staircase will take a turn for the worse, main control computer triggers service brake and additional system at once
Dynamic device carries out brake hard.
Usefulness of the present utility model is compared with prior art：It can judge whether staircase takes a turn for the worse ahead of time, and
When progress brake, it is ensured that the personal safety of passenger；Monochromatic light electricity more saves production cost；Install simple.

Embodiment：
The electric anti-reverse-rotation device of staircase monochromatic light that the utility model is related to, includes a duplex chain wheel 1, double strand chain as shown in Figure 1
The right side of wheel 1 is provided with the optoelectronic detecting device 2 for being used for detecting the duplex chain wheel gear teeth 11, and the optoelectronic detecting device 2 is connected with master control
Computer 3, main control computer 3 is connected to service brake 4 and additional brake 5, and main control computer 3 shows photoelectric pulse wave 30.
Photosignal pulse 30 includes normal burst 31, reverses pulse 32 and pulse spacing 33 as shown in Figure 2.
The optoelectronic detecting device detection double strand chain gear teeth 11, often cross a tooth, form a high level, staircase with normal speed just
Often during operating, photoelectricity will form regular impulse wave, i.e. normal burst 31, and the normal burst 31 is introduced into main control computer, main
Control computer and timing is carried out to the rising edge pulse interval 33 of photoelectric pulse wave 30 when uplink state is high level.When the up mistake of staircase
When will appear from reversing in journey, duplex chain wheel speed slows down first, then stops, and finally reverses, and at this moment photoelectricity waveform is reverse arteries and veins
Punching 32, main control computer, which detects photoimpact rising edge interval time, will become big, can determine that staircase will take a turn for the worse, master control electricity
Brain 3 triggers service brake 4 at once and additional brake 5 carries out brake hard.
It is emphasized that：It the above is only the introduction and description of occupation mode of the present utility model, it is not new to this practicality
Type makees any formal limitation, every any simply to be repaiied according to what technical spirit of the present utility model was made to above example
Change, equivalent variations and modification, in the range of still falling within technical solutions of the utility model.
