Description
Technical field
The present invention is related to a kind of anti-muddy-water device, more particularly to the laser sensor in a kind of railway detection vehicle with anti-
Muddy-water device.
Background technology
At present, domestic large-scale rail-defect detector car uses ultrasound wave to visit the wheel sensing mode as the internal trauma of detection rail,
Ultrasound wave based on bogie no matter is used to visit wheel mounting means or use ultrasound wave based on flaw detection trolley to visit wheel peace
Dress mode, due to rocking and the slacking of gauge etc. in rail-defect detector car running, all inevitably in detection process
Middle generation ultrasound wave visits the lateral displacement deviation between wheel and rail.If this offset deviation can not obtain timely
Correction, cannot ensure that the acoustic beam of ultrasound wave incides inside rail according to the direction of agreement, and cause hindering inside rail
Damage cannot effectively detect, and has serious consequences.
Rail-defect detector car uses centering sensor to realize ultrasound wave and visits the measurement of lateral displacement between wheel and rail, is applied to
The centering sensor of rail-defect detector car mainly has electromagnetism centering sensor based on electromagnetic principle or uses distance measuring method
Laser sensor.Ultrasound wave visits wheel needs lasting injection coupling water to visit wheel to rail and ultrasound wave in the course of the work
Between carry out ultrasonic coupling, it is relatively near that centering sensor mounting location distance ultrasound wave visits wheel, thus cause splash coupling water,
Dust, iron filings and earth etc. accumulate in the window's position of laser sensor or on its sensory path.Laser sensor
Installation window or sensory path on once meet with obstruction, can cause laser sensor cannot effectively obtain ultrasound wave visit
Lateral displacement information between wheel and rail, thus it is ultrasonic to guarantee that horizontal automatic centering system realizes timely and effectively
Ripple visits laterally centering between wheel and rail.
The rapidly and efficiently trauma detection of in-service rail is increasingly dependent on large-scale rail-defect detector car, large-scale rail-defect detector car master
Ultrasonic wheel type probe to be used is as the sensing mode of the internal trauma of detection rail, current large-scale rail-defect detector car just court
And change the direction of flaw detection fast and automatically and develop.Domestic inspection car according to speed class be divided into 40km/h, 60km/h and
80km/h, the lifting of detection speed necessarily causes the required increase spraying the coupling water yield of ultrasonic wave-coupled, also can lead simultaneously
Cause detection vehicle and relative to the transverse shakiness frequency of rail and rock the increase of amplitude.For ensureing that under high-speed cruising, ultrasound wave is visited
The best centering between wheel and rail, inspection car commonly used non-contact laser sensor and servomotor composition
Automatic centering system.Laser sensor is arranged on to be visited on the installing rack of wheel synchronous horizontal motion, for ensureing with ultrasound wave
Inspection car is accurately measuring rail and the lateral displacement amount visited between wheel when curve, it is desirable to laser sensor
Install relative ultrasound wave visit wheel close together.Inspection car need in the course of the work lasting ultrasound wave visit wheel and
Spray coupling water between rail and incide couplant rail within as ultrasound wave, a large amount of spray coupling water, surpass
Water, dust, iron filings and the earth etc. got rid of that run up are taken turns in sound wave spy can accumulate in the sensing window of laser sensor
Place, causes laser sensor cannot effectively obtain the lateral displacement amount between itself and rail.Accumulate in due to coupling water etc.
The laser sensor measured deviation that laser sensor window brings, necessarily causes ultrasound wave to visit wheel and rail longitudinal center puts down
Face is deviateed, thus cannot ensure that ultrasound wave visits the wheel effective detection to rail inside trauma.
Water, dust, iron filings and the earth etc. the got rid of shadow to centering sensor that runs up is taken turns for reducing ultrasound wave spy
Ringing, in prior art, ultrasound wave based on flaw detection trolley spy wheel mounting means have employed and visiting wheel outside increase bucker
Mode is isolated, that is, a ultrasound wave is visited wheel and respectively put a bucker before and after its traffic direction, prevents for two
Water cover is arranged in opposite directions, and it is close that its appearance profile and ultrasound wave visit wheel adventitia shape, and its top uses hex bolts and ultrasonic
Ripple is visited the fixing seat of wheel and is connected, and coupling sprinkler head assembly is installed in its underpart.Visiting wheel adventitia in view of ultrasound wave is flexible material,
Ultrasound wave is visited wheel and is descended Vertical Square upwards to there is the factors such as vibration in working order, the size of bucker and minimum installation position
Put and be all restricted, it is impossible to play the effect of isolation whole water, earth etc., still can at the sensing window of centering sensor
Build up the coupling impurity such as water, earth.
Therefore, it is necessary to provide a kind of new preventer, overcome drawbacks described above.
Summary of the invention
It is an object of the invention to provide a kind of anti-muddy-water device, it is located at the outside of laser sensor, and this anti-muddy water fills
Put can effectively prevent in inspection car running spray coupling water, ultrasound wave visit wheel run up got rid of water, dust,
The impact on laser sensor such as iron filings and earth so that laser sensor can effectively obtain ultrasound wave visit wheel and rail it
Between lateral displacement information, so that it is guaranteed that laterally automatic centering system realize timely and effectively ultrasound wave visit wheel and rail it
Between laterally centering.
