Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flaw detection, and specifically relates to an X-ray non-destructive testing device. Background Technique

[0002] X-ray pipeline detection is a commonly used non-destructive testing (NDT) method that can be used to evaluate the integrity of pipelines. Its basic principle is to utilize the ability of X-rays to penetrate substances. When X-rays pass through a pipeline, materials with different densities or thicknesses will absorb different amounts of radiation. By capturing these X-rays after passing through the materials with a receiver and converting them into images, technicians can analyze these images to identify structural differences and possible defects inside the pipeline.

[0003] In the prior art, for example, a Chinese patent with the authorization announcement number CN212480788U discloses an X-ray non-destructive testing device, which includes a pipeline. The pipeline is a circular pipeline, and a placement block is arranged on the outer side wall surface of the pipeline. The placement block is a rectangular block, and there are two groups of placement blocks in total. Placement grooves are opened at the upper ends of the two groups of placement blocks. The placement grooves are rectangular grooves, and the left and right ends of the placement grooves are open, etc. When the above prior art is used, although this design allows the device to be fixed on the pipeline for detection, the detection range is limited. It can only detect the outside of the pipeline from above, and cannot inspect the pipeline from other directions, resulting in incomplete detection of the pipeline and affecting the overall detection quality of the pipeline. Therefore, an X-ray non-destructive testing device is proposed. Content of the Utility Model

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention.

[0035] Such as Figures 1-6As shown in the figure, an X-ray non-destructive testing device in this embodiment includes: a C-shaped placement rack 1, a rotatable C-shaped adjustment rack 3, a driving mechanism 4, and an X-ray testing device 5. Among them, the C-shaped placement rack 1 is used to place the entire device above the pipeline to be detected. The inner diameter of the rotatable C-shaped adjustment rack 3 is larger than that of the C-shaped placement rack 1, and it is slidably sleeved outside the C-shaped placement rack 1. The rotatable C-shaped adjustment rack 3 can rotate around the center on the C-shaped placement rack 1, thereby changing the positions of its two ends. The driving mechanism 4 is arranged on the side of the C-shaped placement rack 1 and is used to drive the rotatable C-shaped adjustment rack 3 to rotate on the C-shaped placement rack 1. The number of X-ray testing devices 5 is two, which are respectively arranged at the two ends of the rotatable C-shaped adjustment rack 3, and the detection ends are all facing the pipeline to be detected. Thus, by rotating the rotatable C-shaped adjustment rack 3 on the C-shaped placement rack 1, the positions of the two X-ray testing devices 5 can be adjusted, and detection at different angles can be realized.

[0036] It should be noted that the X-ray testing device 5 is a mature existing technology in the field, so no further description will be given.

[0037] Further explanation, the angles between the C-shaped placement rack 1 and the two ends of the rotatable C-shaped adjustment rack 3 are both 180°. The detection ends of the two X-ray testing devices 5 are parallel. Therefore, by rotating the rotatable C-shaped adjustment rack 3 by 90° on the C-shaped placement rack 1, the two X-ray testing devices 5 can complete the detection in the cross direction, and a more comprehensive detection of the pipeline to be detected can be achieved.

[0038] As Figure 4 shown in the figure, the specific structure of the C-shaped placement rack 1 includes two symmetrically arranged C-shaped arms 101. Both ends of the C-shaped arm 101 are provided with support plates 102 extending outwards. The support plates 102 and the C-shaped arm 101 are fixed by welding. A C-shaped guide rod 103 sleeved outside the C-shaped arm 101 is welded between the two support plates 102. The C-shaped guide rod 103 is used to connect the rotatable C-shaped adjustment rack 3.

[0039] It should be noted that the distance between the two C-shaped arms 101 meets the installation distance of the X-ray testing device 5, and there will be no obstacles during the detection of the X-ray testing device 5 through the distance between the two C-shaped arms 101.

[0040] As Figure 6 shown in the figure, the specific structure of the rotatable C-shaped adjustment rack 3 includes a rotating frame 301. The rotating frame 301 is slidably sleeved on the C-shaped guide rods 103 of the two C-shaped arms 101 through two arc-shaped sleeves 302 arranged on its inner side. The arc length of the arc-shaped sleeve 302 is half of that of the rotating frame 301, and one end of it is flush with one end of the rotating frame 301, so as to meet the requirement that the rotatable C-shaped adjustment rack 3 rotates 90° on the C-shaped placement rack 1.

[0041] Among them, the rotating frame 301 includes two semi-circular arms 3010. A plurality of cross bars 3011 are equidistantly arranged between the two semi-circular arms 3010. The two semi-circular arms 3010 are connected into a whole through the cross bars 3011. Two arc-shaped sleeves 302 are respectively welded to the inner sides of the two semi-circular arms 3010.

[0042] It should be noted that there is no conflict relationship between the semi-circular arm 3010 of the rotating frame 301 and the support plate 102 of the C-shaped placement frame 1.

[0043] Two X-ray detection devices 5 are respectively arranged at both ends of the rotating frame 301, and are specifically arranged on the cross bars 3011 at both ends of the rotating frame 301 through fixing frames.

[0044] As Figure 3 shown, an arc-shaped toothed plate 303 is welded to the side surface of the rotating frame 301 to make it rotate by itself, and the arc length of the arc-shaped toothed plate 303 should meet the requirement of rotating the rotatable C-shaped adjusting frame 3 by 90° on the C-shaped placement frame 1.

[0045] The specific structure of the driving mechanism 4 includes a mounting seat 401 welded to the side surface of the C-shaped arm 101. A driving device 402 is mounted on the mounting seat 401. The output end of the driving device 402 is provided with a transmission gear 403 meshing with the arc-shaped toothed plate 303. When the transmission gear 403 rotates, the rotating frame 301 will rotate clockwise or counterclockwise on the two C-shaped arms 101.

[0046] It should be noted that the driving device 402 is composed of a motor and a speed reducer.

[0047] During use, when the two X-ray detection devices 5 complete the horizontal detection, the rotatable C-shaped adjusting frame 3 is driven by the driving mechanism 4 to complete a 90° rotation on the C-shaped placement frame 1, so that the longitudinal detection can be completed by the two X-ray detection devices 5.

[0048] It can be understood that when the arc-shaped sleeve 302 completes a 90° rotation, the limiting effect can be achieved through the conflict relationship with the support plate 102.

[0049] In another embodiment, as Figures 1-5 , it further includes a moving clamping mechanism 2. There are two groups of the moving clamping mechanisms 2, and they are respectively arranged on the separated sides of the two C-shaped arms 101 for movably mounting the C-shaped placement frame 1 on the pipeline to be detected.

[0050] In this way, the detection position can be adjusted by moving the whole device. At the same time, since the overall structure adopts a C-shaped design and is arranged above the pipeline, the obstacles for support below the pipeline can be effectively avoided.

[0051] Among them, the mobile clamping mechanism 2 includes a mounting plate 201 welded to the side of the C-shaped arm 101. A telescopic cylinder 202 whose telescopic end penetrates through it is fixedly installed on the mounting plate 201, and a self-driven magnetic adsorption traveling wheel 203 is fixedly installed on the telescopic end of the telescopic cylinder 202.

[0052] During use, the telescopic cylinder 202 can adjust the extension degree of the self-driven magnetic adsorption traveling wheel 203 according to the diameter of the pipeline to be measured, so as to meet pipelines with different diameters.

[0053] It should be noted that in this embodiment, the pipeline to be detected is a steel pipe to meet the magnetic adsorption effect of the self-driven magnetic adsorption traveling wheel 203. The self-driven magnetic adsorption traveling wheel 203 is a mature existing technology, so it will not be described in detail here. In addition, the number of each group of mobile clamping mechanisms 2 should be determined according to the magnetic adsorption required by the overall equipment.

[0054] In addition, the wheel body of the self-driven magnetic adsorption traveling wheel 203 is a concave wheel, and its concave surface is adapted to the pipeline to be detected, so that the self-driven magnetic adsorption traveling wheel 203 fits better with the pipeline to be detected.

[0055] Furthermore, the mobile clamping mechanism 2 further includes a vacuum chuck 204 arranged on the mounting plate 201. The vacuum chuck 204 is connected to a vacuum generating device through a vacuum pipeline. Through the suction force of the vacuum chuck 204, the adsorption capacity of the overall equipment can be further improved.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
