Description
Technical field
The present invention relates to pantograph carbon slide air-leakage test fields, and in particular to a kind of pantograph carbon slide air-tightness inspection
Survey device and its detection method.
Background technique
Currently, being examined into the water for the air-leakage test of pantograph pan or by pantograph pan in the market
It surveys or injects high pressure gas into pantograph pan, remaining high pressure in the air flue of pantograph pan is detected after a period of time
The surplus or air pressure of gas compare the air-tightness of air pressure or surplus changed to judge pantograph pan by analyzing.But
In actual use, above-mentioned detection method there is problems:
Firstly for using pantograph pan to be put under water, the detection method of pressure-air is then injected into pantograph pan
For, the pressure that pantograph pan will receive water to it after being put under water, at this point, if there is subtle split on pantograph pan surface
Seam, then since bubble is smaller after gas evolution, bubble will not leave pantograph pan surface floating under the action of the pressure of water,
But it is close to fracture faces, therefore, it is necessary to detect whether its surface has bubble by the artificial pantograph pan of overturning in water, this
Sample is limited to the energy of people, is difficult accurately to detect whether pantograph pan surface has crack, therefore detection effect is not ideal enough,
It is easy missing inspection；
Secondly, for the detection method for injecting pressure-air in those air flues to pantograph pan, in detection process
Need to take some time wait after be just capable of measuring gas pressure intensity or gas surplus in air flue, then again to testing result into
Row analysis, which is compared, draws a conclusion, therefore detection takes a long time, and cannot detect immediately as a result, time cost is too high.
Summary of the invention
The object of the invention is that providing a kind of pantograph carbon slide air-leakage test dress to solve the above-mentioned problems
It sets and its detection method, it is not accurate enough with the pantograph pan air-leakage test or detection that solve traditional in the prior art, hold
It is easy to miss inspection or detects the problems such as taking a long time.Preferred technical solution can be real in many technical solutions provided by the invention
Air-tightness that is now accurate, rapidly detecting pantograph pan, and without artificial detection, therefore can guarantee to detect for a long time
Reliability can obtain testing result immediately, detect speed block and without waiting for a period of time, high-efficient, practicability is good etc.
Technical effect, elaboration as detailed below.
To achieve the above object, the present invention provides following technical schemes:
A kind of pantograph carbon slide air-tightness detection device provided by the invention, the band including rack and fixed installation on the rack
Formula conveyer, the belt conveyor is longitudinally mounted on the rack, is fixedly mounted vertically on the conveyer belt of the belt conveyor

In hole (10), then start air flow dryer (13), hot wind enters in air flue through air inlet pipe (25) by moisture remaining in air flue
Drying；
Step 6: dry the pantograph pan (5) that finishes with belt conveyor (2) continuously move to operator it is current after, behaviour
Make worker and will test qualified pantograph pan (5) and underproof pantograph pan (5) according to the state of alarm lamp (9) to remove
And separate storage.
7. a kind of pantograph carbon slide air-tightness detection method according to claim 6, it is characterised in that: in step 5 when
When pantograph pan (5) to be detected is moved to the dead astern for the detection bar (12) connecting with water tank (14), detect finish by
Pantograph slider (5) is also just moved to the dead astern for the detection bar (12) connecting with air flow dryer (13).
