Description
Technical field
The present invention relates to the device and method in a kind of X-ray detection field, specifically a kind of small-sized cylinder girth joint
Ray automatic detection device.
Background technique
X-ray detection technology is widely used in as one of common non-destructive testing technology of weld seam Inner Defect Testing
The fields such as Aeronautics and Astronautics, ship, petrochemical industry, special equipment manufacture.There are two types of arrangements for currently used X-ray production apparatus: one
Kind is orientation X-ray production apparatus, and transillumination angle of radiation is relatively fixed, and transillumination low efficiency is used primarily in the detection of straight weld；In addition
One kind is circumferential X-ray production apparatus, and transillumination angle of radiation is 360 °, and transillumination is high-efficient, is widely used in the detection of girth joint.
At the same time, the application of the circumferential transillumination technology of girth joint is more demanding for the relative position of X-ray production apparatus, it is desirable that circumferential X is penetrated
The central axis of line machine is overlapped with the central axis of disk where girth joint, is otherwise easy to cause girth joint various point locations practical
Focal length deviation when detection and influence testing result.Particularly with there are for the cylinder of a plurality of girth joint, grown according to fixed
The guide rail of degree carries out the movement and positioning of circumferential X-ray production apparatus, and guide rail front end position will cause office to the ray of circumferencial direction
Portion is blocked, according to the guide rail that length adjustably adjusts, in view of circumferential X-ray when detecting for the long range of a plurality of girth joint
Machine tube head weight, guide rail are influenced to be also easy to produce deformation when stretching out longer by X-ray machine X tube head gravity, not can guarantee circumferential X-ray production apparatus and are begun
Final position is in girth joint center.It, can be in addition, for the circumferential X-ray detection technique of similar girth joint a plurality of over long distances
It carries circumferential X-ray production apparatus tube head using moving trolley to be detected, moveable carriage traditional at present is generally be directed to single straight
The girth joint of diameter specification uses relatively fixed position height, can not adapt to the circumference weld inspection of different size；Or it although adopts
With liftable structure meet different height position adjust, but due in traveling process can not to trolley go up and down relative position such as
The transillumination position of anterior and posterior height, left and right horizontal, advanced positions and ray beam center and girth joint is monitored in real time and is adjusted,
So that detection quality not can guarantee, circumferential detection technique answering in long cylinder circumference weld inspection is also limited to a certain extent
With.So that at present during atual detection still to orient based on the transillumination characterization processes of X-ray production apparatus segmentation and regionalization, technique
Multiple rotating cylinder is generally required in implementation process or X-ray machine X is made to carry out moving detection along the concentric loop of girth joint periphery,
Low efficiency, large labor intensity.For the detection of a plurality of girth joint of long cylinder of mass, the bad of transillumination technology is oriented
Gesture just seems more prominent.Therefore, it is necessary to seek a kind of circumferential X-ray production apparatus suitable for the polycyclic weld seam of the long cylinder of different-diameter from
