Ray inspection machine is divided to two kinds of directed radiation, circumferential radiation.Directed radiation be it is fixed, beam radiation coning angle is generally at 40 °
~45 ° of ranges.Circumferential radiation beam be with radiation X ray simultaneously on 360 ° of circumference of the X-ray tube axis at vertical direction,
This shines the circular weld of detection large-caliber pipe fittings and spherical container by the flaw detection that single exposure can complete entire weld seam
It mutually works, thus can greatly improve detection efficiency.
The detection of metallic conduit is generally needed to select circumferential radiation x-ray flaw detector, existing circumferential radiation X-ray
Defectoscope requires defectoscope to need to be placed on inside pipeline during the work time, and requires radiographic source can inside revolving body
Accurate focusing, it is very troublesome that this is arranged different bracket focusings for the pipeline of variable diameter, in practical operation, and detection is caused to be imitated
Rate is low.
To solve the above-mentioned problems, Chinese patent CN201420647637.5 discloses a kind of tapered pipeline and is visited with X-ray
Hurt device, and specifically disclose following technical characteristic: the tapered pipeline x-ray inspection device includes walking dolly, described
By one connecting screw set of screw rod on walking dolly, the screw rod, which is put on, connects circumferential radiation x-ray flaw detector by bracket,
The center of the screw rod set and the circumferential radiation x-ray flaw detector is on same horizontal line, in the screw rod set
Face has two sections of contrary internal screw threads, and the screw rod set top connects top contact block, the screw rod by screw rod two
One with the equal length of the screw rod two, the walking dolly spiral shell equal, described with the height of top contact block
The two sides of rod set are wound with contrary drawstring.When advancing to the position of pipeline reducing diameter, corresponding drawstring is pulled from the outside
So that the rotation of screw rod set is so that screw rod set moves up or down, drive circumferential radiation x-ray flaw detector is in pipeline center.
The mode that this drawstring is adjusted is during use and inconvenient.
Summary of the invention:
