Description
Technical field
The utility model relates to the probe cassette technical field, mainly is applicable to the adjustable probe cassette of probe.
Background technology
For guaranteeing safety of railway traffic, in the Heavy-rail Production process, need it is pursued the online UT (Ultrasonic Testing) of Zhi Quanchang, wherein; 6 probes are adopted in the flaw detection of the web of the rail altogether; Packing is fixed in two probe cassettes, and probe cassette is installed on the undercarriage, undercarriage possess move forward and backward, and up-down adjustment function.During detection, probe cassette moves forward in company with undercarriage, makes the probe that is fixedly mounted in the web of the rail probe cassette be resisted against the web of the rail face of rail to be checked, and the between water flowing is coupled, and accomplishes the flaw detection to whole section rail web of the rail face through rail flowing on production line.
In the reality flaw detection, in the investigative range of confirming, finding the defective of prescribed level, before the flaw detection, need line flaw detection equipment is carried out sensitivity correction, the equivalent pairing comparision is adopted in its bearing calibration.This method at first needs to make the heavy rail appearance rail that has artificial defect by relevant criterion, and wherein web of the rail defective is the flat-bottom hole of 6 ￠ 2mm, and difference in height is 10mmm, and level error is 45mm.Then, undercarriage drives the probe cassette reach, makes the probe that is fixedly mounted in the probe cassette be resisted against the web of the rail face of comparison sample rail.Subsequently; Regulate the undercarriage that probe cassette is housed at above-below direction, make in the probe cassette 3 any one of probes aim at its corresponding artificial defects, when the reflection wave of artificial defect up to when the highest; Regulate the sensitivity of this probe; Make reflection wave up to appointment percentage value to full wave height, and with this wave height as the benchmark wave height, the flaw detection sensitivity of this moment is as reference sensitivity.At last, under probe cassette and the fixed situation of probe, use the same method and regulate the sensitivity of two probes of residue, after the sensitivity adjusting of three probes finishes, the detection of beginning heavy rail line flaw detection.
This kind sensitivity adjusting method is the adjusting method under kind of the perfect condition; Promptly give tacit consent to probe cassette and all be in horizontality with the appearance rail; Both are parallel to each other, as long as in the probe cassette 3 probes have 1 to aim at corresponding people's industrial injuries on the appearance rail, two other probe has just been aimed at people's industrial injury that it is corresponding.In the actual production process, because the gap of each assembly of undercarriage self and the wearing and tearing of heavy rail conveyor roller can't guarantee that probe cassette and appearance rail all are in horizontality; Can not guarantee that promptly 3 probes in the probe cassette aim at a kind rail people industrial injury simultaneously; And obtain best reflection echo, reach the benchmark wave height in order to make wave height, the sensitivity of two probes of increase subsequent adjustment that then can only be artificial; Make the flaw detection sensitivity of correction higher; During with this sensitivity flaw detection, can amplify the defect reflection wave height, cause the part defectiveness but below standard qualified rail is judged by accident and become to hinder rail.
Therefore, can web of the rail probe accurately be aimed on kind rail web of the rail people from position industrial injury and carry out the correction of detection sensitivity, determined the accuracy of web of the rail probe detection sensitivity.
