Easily cause erroneous judgement and leakage is visited.
Conventional general purpose ultrasound defect-detecting equipment, mostly A types are shown, single-channel, are adapted to single probe scanning by hand, are detected
Defect be generally the volume shape defect easily detected, and to being easiest to cause the plane defect of brittle fractures of rail to be then difficult detection.
Conventional general A types show shape information when although defect-detecting equipment is able to record that flaw detection, but can not record flaw detection
During probe scanning when positional information, also just can not whole dynamically recording and play back defect image show, can not be effective
Result of detection is analyzed, it is impossible to which result of detection is effectively reviewed, it is impossible to effectively multiple result of detection is effectively contrasted.

Steel rail welding line ultrasonic detection device configures 3 pairs of probes, with 6 kinds of scanning modes, and wherein 2 probes of rail head can be with
The K-type scanning of rail head bit plane shape defect is realized, 2 probes of the flange of rail can realize that the K-type of flange of rail bit plane shape defect is swept
Look into, 2 probes of the web of the rail can be realized in the tandem scanning of the web of the rail and its plane defect of extending part, 3 pairs of probes of the above
1 probe in every 1 pair of probe can realize the scanning of corresponding site volume shape defect.Coordinate special defect-detecting equipment, can be with one
The peaceful planar defect of volume shape defect in secondary quick detection weld seam, detection efficiency is high.Existing flaw detection by hand specified in standard
Calibration block can not fully meet the sensitive calibration needs of ultrasonic detection device：
(1) plane flaw sensitivity calibration
GHT-1 test blocks can meet functional requirement.
(2) volume shape flaw sensitivity is calibrated
GHT-3 test blocks can not meet requirement.Mainly due to following reason：It is different from the calibration of manual flaw detection sensitivity, use
During special-purpose ultrasonic detection means GHT-3 test blocks can not be used to complete：
1) when single probe is detected a flaw by hand, calibration flaw detection sensitivity calibration, scanning of being detected a flaw during calibration are carried out using GHT-3 test blocks
Face is rail tread, and actual scanning face can be tread or rail head side or be the flange of rail when being detected a flaw after sensitivity calibration
Sideways, inclined-plane etc., the i.e. test block can meet the single probe flaw detection sensitivity calibration by hand of weld seam different parts.
2) sensitivity calibration scanning face and actual scanning face of detecting a flaw are identical when ultrasonic detection device is detected a flaw, i.e., the web of the rail and its
Scanning face is tread when extending part is detected a flaw, and scanning face is rail head two sides when rail head is detected a flaw, and scanning face is rail when the flange of rail is detected a flaw
Bottom two sides, the cross-drilled hole machine direction in GHT-3 test blocks is only applicable to tread parallel to rail tread, perpendicular to rail side
Single sensor sensitivity calibration, it is impossible to which popped one's head in when meeting ultrasonic detection device flaw detection in-orbit rostral face flaw detection and flange of rail side are detected a flaw
When sensitivity calibration.GHT-3 test blocks can not meet requirement.

Carry out sensitivity calibration.Rail head is machined away about 15mm by GHT-3 test blocks along rail length direction, and the flange of rail is machined away into about 55mm,
Embodiment 1
As shown in Figures 2 and 3, the configuration of steel rail welding line ultrasonic detection device is when actually detected, it is possible to achieve (1) complete disconnected
Face is shown：
A types are shown：Show that the different position A of the flange of rail, the web of the rail, rail head three sweeps echo-signal respectively with three windows, often
Individual window can be shown simultaneously can also show that two kinds of echo patterns of hair are received in single transmitting-receiving and one respectively；The two is respectively with different face
Color makes a distinction.
Type B is shown：It can show that the flange of rail, the web of the rail, the B at three positions of rail head sweep figure and weld seam axial imaging figure in real time
Shape, realizes steel rail welding line side surface direction, the imaging in three directions in tread direction and cross-sectional direction and shows first.
Video is shown：Defectoscope directly can be connected with display or projecting apparatus, when welding base flaw detection or playing back, energy
By pattern inspection figure large screen display, be conducive to the analysis and judgement of flaw detection data.
(2) storage, playback and the inquiry of pattern inspection figure
Defectoscope dynamically recording and can store the aobvious letter of the positional information popped one's head in during flaw detection scanning, ultrasonic echo A in real time
Number and image show.When data readback and analysis, it can both select specific A and show echo progress detail analysis, can also change
Different sensitivity carries out different images and shown.This is that this technology is applied in steel rail welding line flaw detection by the country first, should
Some can be difficult to carry out scanning with higher sensitivity when detecting on the weld seam judged, line, then under line by the use of technology
Labor is carried out again, is examined and is judged by accident to prevent leak-stopping and improves detection efficiency on line.Defectoscope can store about 20,000 welderings simultaneously
Seam flaw detection data, can be retrieved during data readback by flaw detection date, flaw detection personnel and self-defined pattern.Flaw detection data both may be used
Exported with USB interface, can also netting twine pattern upload, be easy to detect a flaw data management.
(3) PAC scannings and PAC curves are quantitative
When K-type scanning and tandem scanning are carried out to steel rail welding line with double probe method, although Acoustic Wave Propagation distance is one normal
Number, but when defect is located at diverse location, because probe sound field is restricted by self-propagating and rail interface so that weld seam is everywhere
Acoustic pressure and unequal, when an equal amount of defect is located at weld seam different parts, reflection wave height has very big difference.I.e. defect is anti-
Penetrate that sound wave is not only relevant with propagation distance, can also be relevant with the shape at position residing for defect.This project proposes position width first
Spend the concept of control, i.e. PAC, to be different from range-amplitude display control (DAC).Defectoscope devises PAC scannings and PAC is shown, is
The equivalent size of Accurate Determining defect, and then correctly judge that weldquality provides necessary ways and means
(4) automatic flaw detection and flaw detection perfect adaptation by hand
The passage of fault detection system the 1st~the 6th passage is automatic to steel rail welding line tunneling boring using 3 pairs of probes, 6 kinds of scanning modes
Detection, the 7th passage and the 8th passage are flaw detection passage by hand, and the institute with common defectoscope is functional, can be achieved to common flaw detection
The replacement of instrument.Inspection speed was fast when i.e. the fault detection system has both had automatic scanning, quantify the spy of accurate and tunneling boring intuitive display
Point is outer, also have the characteristics of flaw detection is convenient, flexible by hand.

Finally it should be noted that above example is only to describe the technical solution of the utility model rather than to this technology
Method is limited, the utility model application can above extend to other modifications, change, using and embodiment, and because
This thinks all such modifications, change, using, embodiment all in the range of spirit or teaching of the present utility model.
