Background technology
Ultrasonic detection technology is one of conventional non-destructive testing technology, is widely used in pressure vessel, petroleum pipeline, machine The quality testing link in the fields such as tool part.Ultrasonic probe is the device of transmitting and received ultrasonic signal.Pipeline is carried out During Ultrasonic Nondestructive, because pipeline external surface is in arc-shaped, part echo signal when detecting of being popped one's head in using plane can not connect Receive, easily causing missing inspection influences the precision and accuracy of detection.Air between probe and tested pipeline outer surface can disturb letter Number transmission, reduces the accuracy of detection, therefore needs with water wetting tested pipeline outer surface, and the air excluded between the two makes its tool There is preferable coupling effect.Staff's hand hold transducer moves in tested pipeline outer surface in detection process, is applied on probe Power it is uniform and stable, it is firmly too small or firmly it is uneven easily cause coupling effect difference so that influence detection accuracy, very To the missing inspection for causing some fine defects.Above procedure is inconvenient for operation, and efficiency is low, detection accuracy susceptible.
The content of the invention
Goal of the invention:The invention aims to solve ultrasound examination process operation inconvenience in the prior art, effect The problem of rate is low, there is provided one kind is popped one's head in, and uniform force is stable, strengthens coupling effect, makes operation more convenient and improves detection accurately Property pipeline from coupling ultrasonic detection probe device.
Technical scheme:A kind of pipeline of the present invention from coupling ultrasonic detection probe device, including support section and Rolling portion, the support section include probe, stop nut, shell, spring, and the probe is installed on enclosure, described Probe upper outside is provided with screw thread, and adaptation is provided with stop nut on the outside of the screw thread, and the spring is installed under the probe Between portion and the enclosure;The rolling portion includes roller, axle, connecting rod, fastening screw;The axle assembles through roller In one end of connecting rod, the other end of the connecting rod is assemblied on shell by fastening screw;The probe is connected super by wire Sonic wave detector.
Further, the probe is popped one's head in for square curved surface, and its curved surface diameter is consistent with tested pipeline outer surface diameter.
Further, the enclosure bottom center section is curved surface, its curved surface diameter and tested pipeline outer surface diameter one Cause.
Further, the length of the spring in a free state is more than the length of screw thread set by probe top.
Further, the roller is made up of the material with strong absorptive energy, and the material is flexible material, and shape is easy Change.
Detection method the invention also discloses a kind of above-mentioned pipeline from coupling ultrasonic detection probe device, including it is as follows Step:
(1) tested pipeline outer surface is cleaned totally, testing staff holds this pipeline and filled from ultrasonic detecting probe is coupled Put, roller is dipped in a moment in water, taken out after it fully absorbs water;
(2) adjustment fastening screw makes roller be contacted well with tested pipeline outer surface;
(3) outer casing bottom curved surface is fully contacted with tested pipeline outer surface and is moved along tested pipeline outer surface, move Water during dynamic in roller is extruded wetting tested pipeline outer surface, strengthens coupling effect;
(4) probe fully contacts the phenomenon for avoiding discontinuity with tested pipeline outer surface under the action of the spring;
(5) waveform signal received is passed to supersonic reflectoscope by probe by wire, and supersonic reflectoscope is shown Go out stable waveform and complete the detection of this part.
Beneficial effect:The present invention will be provided with spring between probe and shell, probe uniform force is stable, avoids because of stress Uneven and caused missing inspection and coupling effect bad phenomenon;During detection, the systemic water of roller is extruded, by tested pipeline table Face wetting excludes the air between probe and tested pipeline surface, strengthens coupling effect, makes operation more convenient and improves detection Accuracy.
