Abstract
The invention relates to an ultrasonic flaw detection device. The ultrasonic flaw detection device comprises two bearings, two round steel bars, four through groove steel belts of which middle parts are provided with through grooves, two first elastic steel belts, two Teflon belts and two second elastic steel belts. The two round steel bars are respectively inserted into the two bearings and closely fit to inner diameters of the two bearings. The two first elastic steel belts are located at two sides of the bearings between the two round steel bars, are perpendicular to the two round steel bars and are fixed to the two round steel bars by welding. The two round steel bars are fixed to the two first elastic steel belts by bolts. The two Teflon belts are respectively located at two sides of the first elastic steel belts. Two ends of each one of the two Teflon belts are respectively fixed to the through grooves in the upper and lower two corresponding through groove steel belts. Middle parts of the two Teflon belts are provided with probe holes. The ultrasonic flaw detection device can adjust and fix an angle of a flaw detector probe, fix relative positions of transmitting and receiving probes, and realize fast and accurate detection of transverse defects.
Description
Technical field
The present invention relates to a kind of thick walled steel tube failure detector, particularly a kind of ultrasonic flaw detecting device.
Background technology
For thick walled steel tube,, produce tiny transversal crack probably if preheat temperature does not reach requirement during welding; Because thickness is big, crackle is very thin, and ray detection is difficult to find; When the offshore platform that the former pipe factory that has makes outlet is used ERW; Owing to do not detect this type defective, after detecting at the scene, caused tremendous loss.Directly detected a flaw in welded joints with probe afterwards and since face of weld be not peace just, coupling effect just is not so desirable, causes omission and erroneous judgement easily; If probe in the weld seam both sides (one one receipts) detect a flaw, the relative position of head angle and two probes is not fixed, inconvenient operation, speed are too slow, defective also is difficult to detect.This probe fixing device has been arranged, probe in the weld seam both sides (one once receive) detecting a flaw becomes feasible and quick.
Summary of the invention
Technical matters to be solved by this invention provides a kind of ultrasonic flaw detecting device that can carry out fast transverse defect, accurately carry out UT (Ultrasonic Testing).
The technical scheme that the present invention solves the problems of the technologies described above is following: a kind of ultrasonic flaw detecting device, comprise two bearings, and two round steel, four sections centres have the groove steel band of groove, two first flexible strips, two teflin tapes, two second flexible strips;
It is inner and closely agree with its internal diameter that two said round steel insert two said bearings respectively, and said bearing is positioned at said round steel middle part;
Two said first flexible strips between two round steel the bearing both sides and perpendicular to said round steel, fixing with said round steel welding;
On the extended line at the two ends of two said round steel, be respectively arranged with four sections said groove steel bands, said round steel is fixed through bolt and said first flexible strip;
Two said teflin tapes lay respectively at the said first flexible strip both sides; The two ends of said each teflin tape are fixed on two grooves in the said groove steel band through the movable bolt activity respectively; Each said teflin tape middle part is provided with probe hole; Said probe hole is identical with probe size in the defectoscope, and on the teflin tape in the said probe hole outside, passes through bolt;
The two ends of each said second flexible strip are fixing with the middle part welding of said first flexible strip and said teflin tape respectively, and said second flexible strip is positioned at the upper strata of said first flexible strip and said teflin tape.
The invention has the beneficial effects as follows: can regulate, fix the angle of defectoscope probe, and the relative position of fixed transmission and receiving transducer, thereby detect transverse defect more fast and accurately.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the probe hole in the middle part of the said teflin tape is circular or square.
The beneficial effect that adopts above-mentioned further scheme is all to be suitable for for circular or square probe.
