Description
Technical field
The present invention relates to a kind of pipe crawling device, and in particular to the servicing unit for pipeline non-destructive testing.
Background technology
Non-Destructive Testing is exactly Non Destructive Testing, and abbreviation is NDT, also cries nondestructive inspection, is not damage
Or on the premise of not influenceing detected object performance, using the principle art such as ray, ultrasound, infrared, electromagnetism and combine instrument
Device carries out defect, chemistry, the technology of physical parameter detection to material, part, equipment.It is common as in ultrasound examination weld seam
Crackle.Non-Destructive Testing association of Chinese Mechanical Engineering Society is Chinese Non-Destructive Testing academic organisations, and TC56 is its standardizing body.Nothing
It is the essential effective tool of industrial development to damage detection, and a national Industry Development Level is reflected to a certain extent,
Its importance has gained public acceptance.China has set up nationwide Non-Destructive Testing academic organisations in November, 1978 --- China's machinery
Non-Destructive Testing branch of Engineering society.In addition, the industry such as metallurgy, electric power, petrochemical industry, ship, aerospace, nuclear energy has also been set up each
Non-Destructive Testing association or association；Part provinces, autonomous regions and municipalities and prefecture-level city have set up provincial, prefecture-level Non-Destructive Testing
Meeting or association；Zonal Non-Destructive Testing association or association are also each set up in the regions such as northeast, East China, southwest.In lossless inspection
In terms of the fundamental research and instrument and equipment exploitation of survey, still there is larger gap between China and advanced country in the world, especially
It is even more so in terms of the new and high technology detection device such as infrared, sound emission.Conventional lossless detection method：EDDY CURRENT, penetrate
Five kinds of line photograph inspection, ultrasound detection, Magnetic testing and liquid penetration examination.Other lossless detection methods：Acoustic emission detection, heat
Picture, the inspection of infrared, leak test, alternating-current field measurement technology, leakage field, far field test detection method, ultrasonic wave diffraction time difference method etc..
Existing pipe detection typically uses climbing robot, but climbing robot can only typically be transported above pipeline
It is dynamic, it is impossible to realize the motion around conduit axis.
The content of the invention
The technical problems to be solved by the invention are that existing pipe detection typically uses climbing robot, but creeper
Device people typically can only be in pipeline upper direction, it is impossible to realize the motion around conduit axis, it is therefore intended that provide lossless for pipeline
The servicing unit of detection, solves existing pipe detection and typically uses climbing robot, but climbing robot typically can only be
Pipeline upper direction, it is impossible to the problem of realizing around the motion of conduit axis.
The present invention is achieved through the following technical solutions：
For the servicing unit of pipeline non-destructive testing, including hydraulic cylinder, rotating push rod, in addition to housing and pass through hydraulic pressure
The power set of cylinder, rotating push rod and housing connection；The housing by matched with pipeline arc frame, be connected along arc with arc frame
The part of link three of two supports of support and connection of two tangent line extensions of shape frame is constituted, and the hydraulic cylinder is connected to link
On, power set are contacted with pipeline outer wall.Pipeline is nested in by outer inframe by the housing in said structure, passes through power set
Make equipment along pipe motion, when needing to rotate around conduit axis, rotating push rod action is rotated by 90 ° power set, then
Power set work be can be achieved, and in the presence of housing, equipment will not be fallen down from pipeline.
The section center of circle of the pipeline is located on hydraulic cylinder extension direction.Ensure under any situation, power set with
Pipeline is compressed, it is to avoid skidded.
The arc frame is matched by the ball being arranged on inwall with pipeline outer wall.Reduce the resistance between housing and pipeline
Power.
The power set are matched by roller with pipeline outer wall.Loss to pipeline is connected with pipeline most by roller
It is small, while other connected modes such as crawler belt can be used.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is used for the servicing unit of pipeline non-destructive testing, can be revolved with auxiliary ultrasonic failure detector around conduit axis
Turn；
2nd, the present invention is used for the servicing unit of pipeline non-destructive testing, simple in construction, safe, in electronic system failure
In the case of also can guarantee that safety.
