The front support 3 of car body can bore target for the conventional type XXGH-2505(of one with the installation of rear support 6) it is configured so that the central axis of X-ray production apparatus is parallel with position axis in car body and is positioned at vertical vertical plane, and error is within the limits prescribed。
3) installation of relevant apparatus on anchor ear band
By Fig. 4 position, laser positioning mechanism is installed, the overcoat I 25 of laser positioning mechanism be arranged at anchor ear with cross-arm 14 correspondence axially and the anchor ear hoop axes intersect position with front ring 15, by Laser Measurement bundle axis, distance adjustment from horizontal plane all around confirms。Laser instrument positioning pipe 18 should be able to be stablized, smooths, rotate continuously。Go to the fore-and-aft direction distance from horizontal plane by Laser Measurement axis, regulate and confirm that levelness controls in the scope required；Laser Measurement axis goes to the left and right directions distance from horizontal plane, by adjusting bolt, longitudinal amplitude of accommodation of laser beam axis is met regulation requirement。Video camera fixed cover 21 should be installed on the side of laser instrument positioning pipe 18, horizontally rotates radius and observable beam axis 0 °～90 ° and rotates projection and range for suitable not affecting laser instrument positioning pipe 18。Video camera wiring controls end 17, patch panel 16 should be securely fixed in anchor ear with on the relevant position on ring 13 after cross-arm 14 and anchor ear band。
4) body is partially installed in body part
Body is partially installed on the assigned position of body part, being arranged on the rubber blanket 4 in the rear support in inner groovy in conjunction with protuberance of X-ray production apparatus 19, the front of X-ray production apparatus 19 is pressed in front support by rubber blanket 4, and anchor ear is with the cross-arm axis 0 position through the positive upper end of exposure device。Regulate the rubber blanket 4 in front support 3 and rear support 6, the discrepancy in elevation making front support 3 and rear support 6 matches with joined type overall dimensions, it is ensured that the centerline parallel of body center's line and car body, generally within same vertical vertical plane, and substantially parallel with horizontal plane, error meets the requirements。
5) coupling of laser instrument regulates fixing
By regulating anchor ear with the clamping screw of ring 13 after front ring 15 and anchor ear band and adjusting bolt 20, measure and confirm in laser instrument positioning pipe 18 rotation process, the fluctuating error of the passed plane of beam axis and with the depth of parallelism of horizontal plane in prescribed limit。Measuring beam axis and the distance of body axis, measure the two beam axis intersection points distance from exposure ring place plane, according to pipe under test internal diameter, calculate half chord length of beam axis place plane and internal diameter of the pipeline cross section intersection。Laser instrument positioning pipe 18 is turned to the position with body axis parallel and launches beam axis, the luminous point making beam axis projects on the adjustment cushion block being placed in exposure ring 22 relative position, measures the distance of half chord length in exposure plane of a loop and beam axis plane from luminous point by Steel Ruler。The location point of labelling record half chord length, rotates laser instrument positioning pipe 18 and makes beam axis project this position, fastened by the stop clamping screw 30 of laser instrument positioning pipe 18。
By dead ring 5, with high-tension elastic band, body part is tightly connected with body part。
Pipeline section 23 is connected by straight joint 24, and is fastenedly connected with adapter end 9, is connected to need length。
6) connection of terminals is fixed
Connect video camera with corresponding connecting line and control end 17 with video camera wiring, connect terminals and the patch panel of X-ray production apparatus with power line, cable, fasten cable with cord by cable fixing hole 10, with safety rope by insuring bolt jail, hole 11 safety rope。
Open laser instrument and video camera switch, entrance to be checked is advanced by installing the pipeline hoop butt welded joint X-ray production apparatus conveying positioning exposure apparatus combined, the distance of measure center focal position and tube wall, by regulating front support 3 and rear support 6 with rubber blanket 4, making center of circle focus axis and pipe axis essentially coincide, error is in prescribed limit。Continuous spreading push rod, carries positioning exposure apparatus to be transported to weld bond to be checked pipeline hoop butt welded joint X-ray production apparatus, when observing the weld seam that laser spot projects weld bond to be checked, stops conveying；Can confirm that now exposure ring is vertically opposite with weld bond to be checked, body axis and central axis essentially coincide, and can complete the disposable exposure of high-quality pipeline hoop butt welded joint by selected exposure parameter。
What finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent replacement, without deviating from objective and the scope of technical solution of the present invention, it all should be encompassed in the middle of scope of the presently claimed invention。
