Description
Technical field
This utility model relates to a kind of ultrasonic probe clamping device, particularly relates to the probe voussoir clamping device of a kind of applicable ultrasonic nondestructive test of pipeline.
Background technology
Small diameter tube generally refers to the metallic conduit that external diameter is 21.3～159mm, relatively broad in field application such as petrochemical industry, bearing device, boiler manfacturing, power industry, Nuclear Power Industries.The feature of this type of pipe fitting is that radius of curvature is little, and pipe thickness is thin, and Construction Arrangement is compact.Therefore being of wide application of class pipeline, once occurs the biggest probability of problem can even cause the major accident such as environmental pollution or blast, so must assure that the performance of this type of pipe fitting meets use and safety requirements to producing and life produces harmful effect.
The detection of pipeline includes weld seam detection and body detection, and weld seam detection is divided into circumference weld inspection and longitudinal seam detection, girth joint be i.e. weld seam along pipeline circumferentially around a circle, longitudinal seam is i.e. axially extending along pipeline；Body detection includes Corrosion monitoring and crack detection.Pipe detection typically uses Non-Destructive Testing mode; i.e. on the premise of not damaging or not affecting detected object serviceability and interior tissue; utilize material internal structure exception or defect exist cause heat, sound, the change of the reaction such as optical, electrical, magnetic; with either physically or chemically as means; by up to date technics and equipment and material, to test specimen inside and the type of the structure on surface, character, state and defect, character, quantity, shape, position, size, it is distributed and changes the method checking and testing.Non-Destructive Testing mode conventional in Practical Project includes ray detection, Magnetic testing, Liquid penetrant testing and ultrasound detection etc..
During Ultrasonic NDT, surface of the work is often the most coarse because of the reason such as oxide layer or rust corrosion, if directly and absorption surface easilys lead to rapid wear of popping one's head in by probe, shortens the probe life-span.Therefore, practical operation often increases between probe and measured workpiece the medium of removable, relative low price in order to substitute abrasion, the most so-called voussoir.Voussoir need to be provided continual and steady downforce to fit tightly both ensureing by detection process, makes coupling effect reach testing requirement, otherwise will be unable to detect.Owing to voussoir tool itself has the dimensions and hardness, if not having enough degree of freedom, pressure obviously cannot meet decoupling calls the most on the lower.
The probe voussoir clamping device of small diameter tube Ultrasonic NDT, it is desirable to during whole detection, clamping device can keep continual and steady laminating to probe voussoir and tested pipeline surface, to reach the testing result of stable and consistent.In Practical Project scene, because of a variety of causes, surface of the work can present deformation and rough situation, and general mechanism is difficult to reach to provide continual and steady laminating in detection process, make coupling effect be difficult to reach stable with consistent, judge to form impact on operating process and testing result.Downforce needed for the generally probe voussoir offer three degree of freedom of product (including but not limited to small diameter tube the cannot-harm-detection device) in the market and laminating, great majority use the design that a displacement+two as shown in Figure 1a rotates, or the design of three rotations as shown in Figure 1 b.For ensureing to rotate smooth and easy and kinematic accuracy, generally increasing the standard component such as bearing or line slideway the outside of U-shaped frame, this causes two problems: one is that mechanism's overall dimensions is bigger than normal, and two is relatively costly.
As it was noted above, the feature of small diameter tube is characteristics of compact layout, the spacing between pipeline is the least, if the overall dimensions of mechanism is excessive, it is easy to situation about blocking, working place is not enough occur in detection process.In order to solve this problem, some devices being applied to small diameter tube Ultrasonic NDT are made that the compromise (compromise proposal) abandoning some freedom, such as, notification number is that the patent documentation of CN 204694677 U discloses a kind of small diameter tube weld seam ultrasonic phase array detection device, as in figure 2 it is shown, this device is in order to avoid oversize, magic tape is used to provide downforce for probe voussoir, therefore it is not required to use bearing or line slideway, is able to compressor size.But the cost done so is the degree of freedom of probe voussoir to be restricted, when in axial direction there is difference in height in pipe surface, probe voussoir cannot carry out good coupling with pipeline, even so, even if detection process probe voussoir can be held against with pipeline, the phenomenon of pine when this kind of mode cannot avoid whole device being caused tight when occurring when caliber changes, causes coupling deviation, and when using this device to check, image repeatable accuracy is low.
From the foregoing, it can be understood that at present small diameter tube circumference weld inspection device the most on the market generally there are two contradictions: one be to ensure that probe voussoir coupling needed for degree of freedom plant bulk can be caused bigger than normal, reality cannot be applied, and relatively costly；If two is to abandon some degree of freedom to reduce overall dimensions, then the voussoir coupling effect that can cause popping one's head in is unsatisfactory for detection demand.
Summary of the invention
The technical problems to be solved in the utility model is to provide the probe voussoir clamping device of a kind of applicable ultrasonic nondestructive test of pipeline, the overall dimensions of this probe voussoir clamping device is less, probe voussoir can be kept to be close to pipe surface, meet the decoupling calls to detection surface, and it is simple and reliable for structure, with low cost, possess the highest application value realistic.The technical scheme used is as follows:
The probe voussoir clamping device of a kind of applicable ultrasonic nondestructive test of pipeline, including probe voussoir and U-shaped frame, is characterized in that: also include the first pin, the second pin, the first rotating shaft, the second rotating shaft, first connecting rod, second connecting rod, the first spring and the second spring；First pin, the fixing end of the second pin may be rotatably mounted at the both sides of described probe voussoir respectively；The end of two straight-arms of described U-shaped frame all offers the bar-shaped trough perpendicular with straight-arm length direction；First pin, the free end of the second pin are respectively in corresponding bar-shaped trough；One end of first connecting rod is fixing with the free end of the first pin to be connected, and the other end of first connecting rod be may be rotatably mounted on the corresponding straight-arm of U-shaped frame by the first rotating shaft；One end of second connecting rod is fixing with the free end of the second pin to be connected, and the other end of second connecting rod be may be rotatably mounted on the corresponding straight-arm of U-shaped frame by the second rotating shaft；The two ends of the first spring connect to the corresponding straight-arm of first connecting rod, U-shaped frame respectively；The two ends of the second spring connect to the corresponding straight-arm of second connecting rod, U-shaped frame respectively.
