DETAILED DESCRIPTION

[0027] The principles and features of the utility model are described below in conjunction with the drawings, and the examples are only used to explain the utility model and not to limit the scope of the utility model.

[0028] Example 1, such as Figs. 1-4 As shown, an adjustable support carriage for circumferential X-ray machine center radiography includes an X-ray machine body 1 and a mobile trolley 2. The X-ray machine body 1 is disposed inside the placement space of the mobile trolley 2. A support component 3 is disposed on the top of the mobile trolley 2, and a fixing component 4 is disposed on the top of the mobile trolley 2. The inner wall of the support component 3 is fitted to the outer wall of the X-ray machine body 1, and the fixing component 4 is engaged with the right side of the X-ray machine body 1. A height adjustment component 5 is disposed at the bottom of both the support component 3 and the fixing component 4. There are three height adjustment components 5, two of which are located below the support component 3.

[0029] Determine the pipe diameter and pre-mark the exposure points of the X-ray machine body 1 inside the pipe fitting. Adjust the height of the support component 3 and the fixing component 4 using the height adjustment component. Then, fix the X-ray machine body 1 above the support component 3 using the fixing component. A professional uses a mobile trolley 2 to deliver the X-ray machine body 1 to the weld to be inspected, aligning it with the pre-marked exposure lines. Then, perform the inspection using the central radiography method. This can reduce exposure time, improve work efficiency, and provide a large single radiographic range. For circumferential welds, it can reduce the number of radiographic exposures, reduce costs, thereby reducing interference from scattered rays, improving sensitivity, and optimizing image quality.

[0030] Example 2 is a further improvement based on Example 1, and is as follows: All height adjustment components 5 include a mounting plate 501, a transmission rod 502, a threaded rod 503, a worm gear 504, and a worm 505. The mounting plate 501 is fixedly mounted on the top of the mobile trolley 2, the transmission rod 502 is rotatably mounted on the top of the mounting plate 501, the threaded rod 503 is threadedly mounted inside the transmission rod 502, the worm gear 504 is fixedly connected to the outside of the transmission rod 502, and the worm 505 meshes with the worm gear 504.

[0031] With this configuration, the worm 505 rotates, driving the worm wheel 504 to rotate, causing the transmission rod 502 to rotate on the mounting plate 501. The transmission rod 502 has a guide pin inside, and the threaded rod 503 has a keyway on its outer side. The guide pin and the keyway cooperate (not shown in the figure, which is a well-known technique in the art, so it will not be described in detail), causing the threaded rod 503 to move up and down in a linear motion.

[0032] The embodiment 3 is a further improvement on the basis of the embodiment 2, and specifically as follows: two worm gears 505 are arranged above the mobile trolley 2 near the left side, the two worm gears 505 are connected through a connecting rod, a first supporting plate 6 is fixedly installed above the mobile trolley 2, the rear side of the worm gear 505 near the rear side of the mobile trolley 2 is rotationally connected to the front side of the first supporting plate 6, and the front side of the worm gear 505 near the front side of the mobile trolley 2 is fixedly connected with a first rotating handle 7. When installing, a protective box (not shown in the figure) also needs to be installed outside the two height adjusting assemblies 5 near the left side of the mobile trolley 2, so that the worm gear 505 at the corresponding position is rotationally connected to the front and rear sides of the protective box.

[0033] In this way, under the action of the connecting rod, the two worm gears 505 can be driven to rotate simultaneously through the first rotating handle 7, so that the two height adjusting assemblies 5 near the left side of the mobile trolley 2 can be adjusted synchronously, and the worm gear 505 can be stably rotated under the action of the first rotating handle 7 through the protective box, and the worm gear 505 at the position is protected by the protective box.

[0034] The embodiment 4 is a further improvement on the basis of the embodiment 3, and specifically as follows: one worm gear 505 is arranged above the mobile trolley 2 near the right side, a second supporting plate 8 is fixedly installed above the mobile trolley 2, the rear side of the worm gear 505 near the right side of the mobile trolley 2 is rotationally connected to the front side of the second supporting plate 8, and the front side of the worm gear 505 near the right side of the mobile trolley 2 is fixedly connected with a second rotating handle 9. When installing, a protective box (not shown in the figure) also needs to be installed outside one height adjusting assembly 5 near the right side of the mobile trolley 2, so that the worm gear 505 at the corresponding position is rotationally connected to the front and rear sides of the protective box.

[0035] The size of the height adjusting assembly 5 near the right side above the mobile trolley 2 is smaller than that of the two height adjusting assemblies 5 near the left side, so that the worm gear 505 at the corresponding position can be more stably rotated when the second rotating handle 9 works, and is limited in a certain range, and the worm gear 505 at the position is protected by the protective box.

[0036] In this way, the two height adjusting assemblies 5 near the left side above the mobile trolley 2 and the one height adjusting assembly 5 near the right side are distinguished, so that the height of the X-ray machine body 1 can be better adapted, and the left and right sides of the X-ray machine body 1 are limited.

[0037] Embodiment 5, this embodiment is a further improvement on the basis of embodiment 2, which is as follows: the support assembly 3 comprises a U-shaped block 301 and a rubber pad 302, the rubber pad 302 is fixedly installed in the inner part of the U-shaped block 301, the inner wall of the rubber pad 302 is attached to the outer wall of the X-ray machine body 1, and the top of the two threaded rods 503 near the left side above the moving trolley 2 is fixedly connected with the bottom of the U-shaped block 301 respectively.

[0038] In this way, the two height adjusting assemblies 5 near the left side above the moving trolley 2 are adjusted in a synchronous driving manner, which can better adjust the position of the U-shaped block 301, and facilitate the change of the position of the X-ray machine body 1 according to the prepared exposure point position, so that the X-ray machine body 1 can work better.

[0039] Embodiment 6, this embodiment is a further improvement on the basis of embodiment 2, which is as follows: the fixed assembly 4 comprises a limiting semi-ring 401, the limiting semi-ring 401 is two, and is rotatably connected, the two limiting semi-rings 401 are fixed through fasteners, and the top of the threaded rod 503 near the right side above the moving trolley 2 is fixedly connected with the bottom of the lower limiting semi-ring 401.

[0040] In this way, the upper limiting semi-ring 401 is clamped with the support frame of the connecting part of the right side of the X-ray machine body 1, so that the X-ray machine body 1 is partially limited, and the position of the X-ray machine body 1 is limited under the cooperation of the support assembly 3, so that the X-ray machine body 1 can work better.

[0041] Embodiment 7, this embodiment is a further improvement on the basis of embodiment 4, which is as follows: the first rotating handle 7 and the second rotating handle 9 are both inserted into the limiting frame 10, and the bottom of the two limiting frames 10 extends into the interior of the moving trolley 2.

[0042] In this way, the first rotating handle 7 and the second rotating handle 9 are limited by the limiting frame 10, so that the height adjusting assembly 5 can be prevented from changing the height position due to poor self-locking effect during use.

[0043] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
