Description
Technical field:
The present invention relates to a kind of staircase monochromatic light electricity anti-reverse-rotation device, belong to staircase security appliance field.
Background technology:
If staircase is during up during the situation such as step chains fracture, main frame displacement, serious overload, can unexpected inverted running,
Passenger can be caused personal injury.Staircase many employings mechanical type or two dephased photoelectricity carry out detecting whether to reverse now
Occur.Once reverse generation, service brake can be triggered and additional brake carries out brake hard, it is ensured that passenger safety.But should
Method can must detect after staircase takes a turn for the worse, and how to make testing result draw in advance, is that this patent realizes
Content.
Summary of the invention:
In order to solve above technical problem, a kind of staircase monochromatic light electricity anti-reverse-rotation device that the present invention relates to, including a duplex chain wheel,
Being provided with the optoelectronic detecting device for detecting the duplex chain wheel gear teeth on the right side of duplex chain wheel, described optoelectronic detecting device connects master control
Computer, main control computer is connected to service brake and additional brake, main control computer display photosignal pulse.
Further, the quantity of described optoelectronic detecting device is one, relatively conventional mechanical type and phase-difference type photoelectricity
Detection, provides cost savings.
Further, described photosignal pulse includes normal burst, reverses pulse and pulse spacing, drives in the wrong direction it at staircase
Before just can demonstrate reverse pulse in advance, it is possible to prevent staircase retrograde timely and effectively.
Optoelectronic detecting device detection duplex chain wheel tooth tip, often crosses a tooth, forms a high level, and staircase is with normal speed
During normal operation, photoelectricity will be formed with the impulse wave of rule, and this pulse is introduced main control computer, and main control computer at uplink state is
During high level, photoelectric pulse wave rising edge interval is carried out timing.When will appear from during staircase is up reversing, duplex chain wheel
First speed slow down, and then stops, and finally reverses, and at this moment light electrical waveform is for reversing pulse, and main control computer detects photoimpact
Rising edge will become big interval time, can determine that staircase will take a turn for the worse, and main control computer triggers service brake and additional system at once
Dynamic device carries out brake hard.
Compared with prior art usefulness of the present invention is: can judge whether staircase takes a turn for the worse ahead of time, timely
It is braked, it is ensured that the personal safety of passenger；Monochromatic light electricity more saves production cost；Install simple.

Detailed description of the invention:
A kind of staircase monochromatic light electricity anti-reverse-rotation device that the present invention relates to, as shown in Figure 1: include a duplex chain wheel 1, duplex chain wheel 1
Right side is provided with the optoelectronic detecting device 2 for detecting the duplex chain wheel gear teeth 11, and described optoelectronic detecting device 2 connects main 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.Photoelectricity
Signal pulse 30 includes normal burst 31 as shown in Figure 2, reverses pulse 32 and pulse spacing 33.
The optoelectronic detecting device detection double strand chain gear teeth 11, often cross a tooth, form a high level, and staircase is with normal speed just
When often operating, photoelectricity will be formed with the impulse wave of rule, i.e. normal burst 31, and this normal burst 31 is introduced main control computer, main
Control computer carries out timing when uplink state is high level to photoelectric pulse wave 30 rising edge pulse interval 33.When the up mistake of staircase
When will appear from journey reversing, first duplex chain wheel speed slow down, and then stops, and finally reverses, and at this moment light electrical waveform is for reversing arteries and veins
Punching 32, main control computer detects that photoimpact rising edge will become big interval time, 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: be the most only introduction and the description of the occupation mode of the present invention, not the present invention made any
Pro forma restriction, any simple modification that above example is made by every technical spirit according to the present invention, equivalent variations
With modification, all still fall within the range of technical solution of the present invention.
