Description

The position regulator that is used for ultrasonic flaw detecting device

Technical field

The utility model relates to a kind of mobile device that is used for failure detector.

Background technology

The heavy caliber straight-line joint submerged arc welding tube of producing in the factory mainly comprises structural pipe, line pipe, and its specification is Φ 508-1422.2mm, and wall thickness is 6mm~40mm.Because pipe adopts submerged arc welding, very easily form the defective of the middle lack of penetration type of wall thickness, may produce transverse defect simultaneously.

The body weld joint ultrasonic automatic flaw detection apparatus that Germany KD company produces has the ability of the lack of penetration and transverse defect of automatic detection.But pipe is after the auto-ultrasonic detection is finished, and we also need off-line that defective locations is manually visited again.For this defective of two types, if adopt the monocline probe to detect, even bring up to very high sensitivity, defective also not necessarily can be leant out again.Therefore, we adopt the method for tandem UT (Ultrasonic Testing) or the flaw detection of K type usually.

As shown in Figure 1, the tandem UT (Ultrasonic Testing) comprises two probes, launches ultrasound wave in front for one, and one receives ultrasound wave in the back.If the weld seam zero defect, ultrasonic waves transmitted is propagated forward, and receiving transducer can not receive signal.When in the weld seam during defectiveness (defective 1,2 of vertical direction in as Fig. 1), the part ultrasound wave is propagated after by defect reflection, through lower surface secondary reflection again, can be received probe and receiving.

When two centres of B1 and B2 position of popping one's head in the drawings are close to when placing, only can find near the defective the root of weld 1.The probe up to the front ran into weld seam and strengthened face, just can send out the defective of the existing weld seam of figure from top to bottom gradually if two probes are moved in opposite direction with equidistance simultaneously this moment.For example two probes when position A1 and A2, can be found the defective at the root of weld 2 places respectively.Whole process, the whole welding line section that has been equivalent to scanning.In like manner, ask in opposite direction when drawing close with equidistance two positions of probe from separating, the whole welding line section that has been equivalent to scanning from top to bottom.

Since be the coupling probe of electronic switch control, its complex structure, the cost height, and use very trouble, limited the application of this inspection technique in actual production.And desire realizes such scanning, is difficult with manual operation, needs to use special scanning equipment.

As shown in Figure 2, the flaw detection of K type is that the butt welded seam transverse defect detects, (as the defective of vertical weld direction among Fig. 2), probe 1 emission ultrasound wave, behind defect reflection, probe 2 receives ultrasound wave.If there is not defective, probe 2 can't receive echo.

Summary of the invention

The purpose of this utility model provides a kind of position regulator that is used for ultrasonic flaw detecting device, can realize that tandem or K type detect, be applicable to the girth seam of heavy caliber welded tube weld seam, dull and stereotyped weld seam and hydrostatic column, the axial automatic ultrasonic inspection of weld seam, effectively increase work efficiency and the standard of detecting a flaw is examined spy rate again.Not only volume is little, in light weight, and stability is high.
