Description
Technical field
The utility model belongs to tubing detection field, is related to pipe internal diameter ultrasound examination, especially a kind of portable pipe
Material internal diameter ultrasound examination bar.
Background technology
Ultrasonic Nondestructive is now widely used Defect detection method, in recent years in the inspection of pipe with small pipe diameter pipe internal diameter
Relatively broad application has been obtained in survey, has been lacked mainly for detection of inside and outside walls such as the crackle of tubing, mechanical scratch, scratch and depressions
Fall into, but ultrasonic guided wave detecting test piece needs to be customized according to the small diameter tube of different size and made, because there is frequency dispersion in supersonic guide-wave
Phenomenon, the required precision to test strip is very high, and the precision of test strip can directly affect echo amplitude, current application technology
It is middle to there is certain defect：
1st, not Guided waves and its test block are made with specific regulation in relevant criterion, therefore in actually detected process
In, certain difficulty is existed to quantifying for defect of discovery, i.e. the inner diameter measurement relative to same tubing, defective section is not known,
Tubing for small internal diameter is detected, it is necessary to using the test strip of substantial amounts of different size be segmented one by one, is wasted time and energy, and
Accuracy is difficult control；
2nd, in working at the scene, need to try using different ultrasonic examination standards because the tubing for needing to detect is different
Block, simulating test pieces and reference block, therefore the carrying amount of test block is larger, and test block is usually steel design, weight and volume are equal
It is larger, bring inconvenience to experimenter.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part can be while meeting different marks there is provided one kind
Accurate regulation requirement, small volume, it is lightweight, be easy to carry and repair, effectively improve the portable pipe internal diameter of detection accuracy
Ultrasound examination bar.
The utility model solves above-mentioned technical problem and takes following technical scheme to realize：
A kind of portable pipe internal diameter ultrasound examination bar, including handle, scale post, the first slip test block and second slide
Test block, handle and the scale post is coaxially connected by extensible member, and described handle is empty for the cylindrical shape of rearmounted detachable dome
Cavity configuration, the first slip test block and the second slip test block are coaxially detachably placed in the cavity cylinder of the handle, described
Scale post be irony cylinder, outer surface is coaxially arranged with some graduation marks, and described first, which slides test block and second, slides examination
Block coaxially slide Demountable assembling is on the scale post, and the first slip test block and the second slip test block are detachably combined, and first
Slide test block side outer and offer positive toothed edge, slided second in test block, side corresponding with the first slip test block is set
There is reverse toothed edge, the positive toothed edge and reverse toothed edge, which are meshed to constitute, slides test block group.
Moreover, the both sides coaxial-symmetrical Demountable assembling in the slip test block group has a pair of rubber spacing collars, the rubber
The diameter of spacing collar is less than the diameter of the slip test block group.
Moreover, described extensible member includes first connecting portion, threaded rod and second connecting portion, described threaded rod one end and the
One connecting portion is threadedly coupled, and the other end is threadedly coupled with second connecting portion, and first connecting portion is connected with the handle, the second connection
Portion is connected with the scale post.
Advantage of the present utility model and have the beneficial effect that：
1st, the utility model coaxially slide Demountable assembling on the cylindrical scale post of irony has several the first slip examinations
Block and second slides test block, and the positive toothed edge of the first slip test block and the second slip reverse toothed edge of test block are meshed, constituted
Slide test block group.Can according to detection tubing actual conditions selection be used alone first slide test block or second slide test block with
And the slip test block group combined, and some graduation marks are coaxially arranged with the outer surface of scale post, can be according to tubing
The length of detection section needed for internal diameter, slides test block to corresponding scale so that detection accurate quantification.In each slip test block group
Both sides coaxial-symmetrical Demountable assembling has a pair of rubber spacing collars, plays a part of spacing fixation, it is ensured that detection it is accurate.
2nd, handle and scale post of the present utility model is coaxially connected by extensible member, and extensible member includes first connecting portion, spiral shell
Rasp bar and second connecting portion, described threaded rod one end are threadedly coupled with first connecting portion, and the other end connects with second connecting portion screw thread
Connect, according to measured pipe length, adjust the length of extensible member, because handle is not contacted with tested tubing, stress can be reduced,
Avoid influenceing measurement result.
3rd, rationally, small volume is easy to carry the utility model design science, effectively finds that defect is carried out to pipe internal diameter
It is quantitative, solve and need to use the test strip of substantial amounts of different size to carry out the problem of segmentation is detected one by one, when saving detection
Between, improve accuracy of detection, and with using it is simple, detect accurate many advantages, such as, it is adaptable to detected at the scene, it is convenient soon
It is prompt.
