[0002] The liquefied petroleum gas cylinder, also known as the gas cylinder, is a steel cylinder for storing gas. The wall thickness of the steel cylinder is about 2.5 mm, and the internal pressure is 0.5 - 1.2 megapascals. During the production of liquefied gas, it is necessary to use a detection device to determine whether there are weld and gap defects in the steel cylinder. In the prior art, the Chinese utility model patent with the publication number: CN217277970U discloses a dual X-ray machine non-destructive testing device. In this utility model, two X-ray machines share a linear array detector. By switching the X-ray machine that cooperates with the linear array detector, two radiation imaging systems with different imaging functions are obtained, which expands the applicable range of the non-destructive testing device and at the same time keeps the structure simple.

[0003] However, in this utility model, the large-focus X-ray machine and the small-focus X-ray machine can only move up and down, and the adjustable angle is limited. Facing the circular structure of the gas cylinder, it is easy to miss some weld and gap defects, so improvement is needed. Content of the Utility Model

[0022] Such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown in the figure, the vertical liquefied gas cylinder detection X-ray machine includes an import roller conveyor rack 1. A detection box 2 is fixedly connected to the side position of the import roller conveyor rack 1. An export roller conveyor rack 3 is fixedly connected to the side position of the detection box 2. An electric control cabinet 4 is fixedly connected to the side position of the export roller conveyor rack 3. An operation console 5 is fixedly connected to the side position of the electric control cabinet 4. An inner roller conveyor rack 6 is fixedly connected inside the detection box 2. A first slide bar 9 is arranged at the side position of the inner roller conveyor rack 6. A first screw rod 10 is movably installed at the side position of the first slide bar 9. A moving block 13 is movably installed on the first slide bar 9 and the first screw rod 10. A rotating frame 17 is rotatably connected to the moving block 13. A moving gear 19 is movably connected to the rotating frame 17. An X-ray source 20 is fixedly connected to one side of the rotating frame 17. A number of conveyor rollers 8 are movably installed on the import roller conveyor rack 1, the export roller conveyor rack 3 and the inner roller conveyor rack 6. A support frame 7 is fixedly connected to the side position of the inner roller conveyor rack 6. The first slide bar 9 is fixedly connected to the support frame 7. Both side rods of the first screw rod 10 are movably installed on the support frame 7 through first bearings 11. A first stepping motor 12 is fixedly connected to the support frame 7, and the output shaft of the first stepping motor 12 is fixedly connected to one end of the first screw rod 10. A support rod 14 is fixedly connected to the moving block 13. The upper end of the support rod 14 is movably installed on the rotating frame 17 through a second bearing 15. A fixed gear 16 is fixedly connected to the support rod 14. A second stepping motor 18 is fixedly connected to the rotating frame 17, and the output shaft of the second stepping motor 18 is fixedly connected to the moving gear 19. When the first stepping motor 12 is started, the first screw rod 10 is rotated, so that the moving block 13 moves. The second stepping motor 18 is started synchronously, so that the moving gear 19 rotates. The moving gear 19 rotates outside the fixed gear 16, so that the rotating frame 17 starts to rotate, and the X-ray source 20 at the other end of the rotating frame 17 is moved closer to or farther away from the cylinder, so as to better adjust the position of the X-ray source 20.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a connecting plate 21 is movably installed inside the detection box 2 at a position below the inner roller conveyor rack 6. A transmission rod 23 is movably installed on the connecting plate 21. A number of pushing wheels 24 are fixedly connected to the transmission rod 23. Partition plates 26 are fixedly connected to both side positions of the connecting plate 21. A cylinder 22 is fixedly connected inside the detection box 2, and the output shaft of the cylinder 22 is fixedly connected to the connecting plate 21. Both side rods of the transmission rod 23 are movably installed on the partition plates 26 through third bearings 25. One end of the transmission rod 23 is fixedly connected to the output shaft of a third stepping motor 27, and the third stepping motor 27 is fixedly connected to the partition plate 26 at one side position. When the connecting plate 21 rises, the partition plates 26 at both ends of the connecting plate 21 move upward synchronously, rising from both ends of the inner roller conveyor rack 6, so as to limit the cylinder on the inner roller conveyor rack 6 and prevent it from being easily separated.

[0024] It should be noted that the present utility model is a vertical liquefied gas cylinder detection X-ray machine. The liquefied gas cylinder is placed horizontally on the import roller conveyor rack 1, and the X-ray source 20 is placed vertically on the side of the cylinder to detect the horizontally placed cylinder. The import roller conveyor rack 1 sends the cylinder onto the inner roller conveyor rack 6 in the detection box 2. The first stepping motor 12 is started to rotate the first screw rod 10, so that the moving block 13 on the first screw rod 10 and the first slide rod 9 moves. The second stepping motor 18 is started synchronously, so that the movable gear 19 rotates. The movable gear 19 meshes with and drives the fixed gear 16, so that the rotation of the movable gear 19 causes the rotating frame 17 to start rotating, and the X-ray source 20 at the other end of the rotating frame 17 is moved closer to or away from the cylinder, so as to better adjust the position of the X-ray source 20. After the position of the X-ray source 20 is adjusted, the air cylinder 22 is started, so that the air cylinder 22 pushes the connecting plate 21 to move upward, so that the connecting plate 21 and the transmission rod 23 move upward synchronously. The third stepping motor 27 is started, so that the transmission rod 23 starts to rotate slowly, and the pushing wheel 24 on the transmission rod 23 starts to rotate synchronously. When the pushing wheel 24 moves to the lower position of the cylinder and contacts the cylinder, the pushing wheel 24 pushes the cylinder to rotate, so that the welds and gaps on the cylinder are fully exposed on the side of the X-ray source 20, making the detection more complete, avoiding omission, and improving the accuracy of the detection result. When the connecting plate 21 rises, the partition plates 26 at both ends of the connecting plate 21 move upward synchronously, rising from both ends of the inner roller conveyor rack 6, so as to limit the cylinder on the inner roller conveyor rack 6, so that when the pushing wheel 24 pushes the cylinder to rotate, the cylinder is not easily separated from the inner roller conveyor rack 6.
