Description

Technical Field

[0001] This utility model relates to the field of pipeline defect detection technology, and in particular to a device for detecting pipeline defects. Background Technology

[0002] X-ray flaw detection is an inspection method that utilizes the ability of X-rays to penetrate metallic materials. Due to the different absorption and scattering effects of X-rays by the materials, the film is exposed to different amounts of light, resulting in images of varying density on the film. This is used to determine the internal defects of the material. After pipe welding is completed, X-rays are often used to detect whether there are any defects in the weld.

[0003] For the detection of pipeline defects, handheld X-ray generators are usually used. However, this method has the problems of low detection efficiency and the risk of X-ray radiation damage to the inspectors. Therefore, we propose a device for detecting pipeline defects to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for detecting pipeline defects, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for detecting pipeline defects includes a workbench. Symmetrical fixed plates are fixedly connected to the upper surface of the workbench. Hydraulic rods are fixedly embedded in the sides of the two fixed plates that are close to each other. An output plate is fixedly connected to the output end of each hydraulic rod. A drive motor is fixedly mounted on the left side of one of the mounting plates. First bearings are fixedly embedded in the sides of the two mounting plates that are close to each other. A rotating shaft is fixedly connected to the inner wall of each first bearing. A positioning plate is fixedly connected to the sides of the two rotating shafts that are close to each other. The left end of one rotating shaft is fixedly connected to the output end of the drive motor. Symmetrical second bearings are fixedly embedded in the inner wall of the workbench. A threaded shaft is fixedly connected to the inner walls of the two second bearings. A first gear is fixedly connected to the outer surface of the threaded shaft. A threaded sleeve is threaded onto the outer surface of the threaded shaft. A servo motor is fixedly mounted on the inner side wall of the workbench. A second gear is fixedly connected to the output end of the servo motor. The first and second gears mesh with each other. A mounting bracket is fixedly connected to the upper surface of the threaded sleeve. An X-ray generator is fixedly connected to the bottom surface of the mounting bracket.

[0007] In a further embodiment, a guide rod is fixedly connected to the inner wall of the workbench, a guide block is slidably connected to the outer surface of the guide rod, and the upper surface of the guide block is fixedly connected to the bottom surface of the mounting frame.

[0008] In a further embodiment, a connecting plate is fixedly connected to the back of the threaded sleeve, and the back of the connecting plate is fixedly connected to the front of the guide block.

[0009] In a further embodiment, each of the two mounting plates has a circular groove on one side that is close to each other, and a circular ring is rotatably connected inside each circular groove. A set of annularly arranged connecting posts are fixedly connected to one side of each of the two circular rings that is close to each other. The ends of the two sets of connecting posts that are close to each other are respectively fixedly connected to the opposite sides of the two positioning plates.

[0010] In a further embodiment, protective pads are fixedly connected to the sides of the two positioning plates that are close to each other, and a set of anti-slip strips arranged at equal intervals are fixedly connected to the sides of the two protective pads that are close to each other.

[0011] In a further embodiment, a baffle is fixedly installed on the back of the workbench by fasteners, and a set of equally spaced heat dissipation windows are opened on the back of the baffle, with a filter screen fixedly connected to the inner wall of each heat dissipation window.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device, through the coordinated use of a servo motor, a second bearing, a first gear, a second gear, a threaded shaft, a threaded sleeve, a mounting bracket, and an X-ray generator, achieves omnidirectional inspection of the inner wall of a pipeline, improving inspection efficiency. The output shaft of the servo motor drives the first gear to rotate, and the first gear meshes with the second gear, causing the threaded shaft to rotate synchronously.

With the drive of the first bearing and drive motor, the rotating shaft can rotate smoothly, causing the positioning plate and the pipeline on it to rotate. This design not only improves detection efficiency but also ensures detection accuracy, providing strong protection for pipeline maintenance and safety. Attached Figure Description

[0025] Please see Figure 1-5 In this utility model, a device for detecting pipeline defects includes a workbench 1. Symmetrical fixing plates 2 are fixedly connected to the upper surface of the workbench 1. Hydraulic rods 3 are fixedly embedded on the sides of the two fixing plates 2 that are close to each other. An installation plate 4 is fixedly connected to the output end of each hydraulic rod 3. A drive motor 5 is fixedly installed on the left side of one of the installation plates 4. First bearings 7 are fixedly embedded on the sides of the two installation plates 4 that are close to each other. A rotating shaft 8 is fixedly connected to the inner wall of each first bearing 7. A positioning plate 6 is fixedly connected to the sides of the two rotating shafts 8 that are close to each other. The left end of one rotating shaft 8 is fixedly connected to the output end of the drive motor 5. Symmetrical second bearings 11 are fixedly embedded in the inner wall of the workbench 1. A threaded shaft 12 is fixedly connected to the inner walls of the two second bearings 11. A first gear 13 is fixedly connected to the outer surface of the threaded shaft 12. A threaded sleeve 14 is threaded onto the outer surface of the threaded shaft 12. A servo motor 9 is fixedly installed on the inner wall of the workbench 1. A second gear 10 is fixedly connected to the output end, and the first gear 13 meshes with the second gear 10. A mounting bracket 21 is fixedly connected to the upper surface of the threaded sleeve 14, and an X-ray generator 22 is fixedly connected to the bottom surface of the mounting bracket 21. Through the above scheme, the second gear 10 is driven to rotate by the servo motor 9. The second gear 10 meshes with the first gear 13, causing the threaded shaft 12 to drive the threaded sleeve 14 to move left and right, thereby adjusting the working position of the X-ray generator 22, which is convenient for detecting different positions of the pipeline. At the same time, the hydraulic rod 3 can drive the mounting plate 4 to move, thereby adjusting the position of the positioning plate 6, so that the positioning plate 6 can clamp and fix pipelines of different lengths, improving the applicability of the device. Under the drive of the drive motor 5, one of the rotating shafts 8 can drive the positioning plate 6 to rotate, so that the clamped pipeline rotates accordingly, which is convenient for the X-ray generator 22 to perform comprehensive inspection of the pipeline. The entire device has a compact structure, is simple to operate, and can efficiently and accurately detect defects in the pipeline.

[0026] A guide rod 27 is fixedly connected to the inner wall of the worktable 1. A guide block 15 is slidably connected to the outer surface of the guide rod 27. The upper surface of the guide block 15 is fixedly connected to the bottom surface of the mounting frame 21. By setting the guide rod 27 and the guide block 15, the movement of the mounting frame 21 can be guided, making the mounting frame 21 more stable during movement and avoiding deviation, thereby further improving the working accuracy of the X-ray generator 22. A connecting plate 16 is fixedly connected to the back of the wire sleeve 14. The back of the connecting plate 16 is fixedly connected to the front of the guide block 15. By setting the connecting plate 16, the wire sleeve 14 and the guide block 15 can be connected, so that when the wire sleeve 14 moves left and right, it can drive the guide block 15 to slide along the guide rod 27, thereby further improving the stability of the X-ray generator 22. The step moves the mounting bracket 21 and the X-ray generator 22, adjusting the working position of the X-ray generator 22. Circular grooves 17 are provided on the sides of the two mounting plates 4 that are close to each other. A circular ring 18 is rotatably connected inside each circular groove 17. A set of annularly arranged connecting columns 19 are fixedly connected to the sides of the two circular rings 18 that are close to each other. The ends of the two sets of connecting columns 19 that are close to each other are fixedly connected to the sides of the two positioning plates 6 that are far apart from each other. By setting the circular grooves 17, circular rings 18, and connecting columns 19, the positioning plates 6 can be supported, making them more stable during rotation and preventing wobbling. This further ensures the stability of the clamped pipe during rotation, thereby improving detection accuracy.

[0027] Protective pads 20 are fixedly connected to the sides of the two positioning plates 6 that are close to each other. A set of anti-slip strips arranged at equal intervals are fixedly connected to the sides of the two protective pads 20 that are close to each other. The anti-slip strips increase the friction between the protective pads 20 and the clamped pipe, preventing the pipe from slipping during rotation and further improving the safety and stability of the testing process. A baffle 23 is fixedly installed on the back of the workbench 1 by fasteners. A set of heat dissipation windows 24 arranged at equal intervals are opened on the back of the baffle 23. A filter screen is fixedly connected to the inner wall of each heat dissipation window 24. The filter screen can filter the air entering the device and prevent dust and other impurities from entering the device and causing contamination or damage to the internal components. Two symmetrical support columns 25 are fixedly connected to the bottom surface of the workbench 1. A support base 26 is fixedly connected to the bottom end of each support column 25. The bottom surface of the support base 26 is provided with anti-slip texture. The anti-slip texture increases the friction between the support base 26 and the ground, preventing the device from sliding during use and ensuring the stability of the device.

[0028] The working principle of this utility model is as follows:

[0029] The servo motor 9 is started, and its output drives the second gear 10 to rotate. The second gear 10 drives the first gear 13, which meshes with it, to rotate. The first gear 13 drives the threaded shaft 12 to rotate, and the threaded shaft 12 drives the threaded sleeve 14, which is threaded to it, to move. The threaded sleeve 14 drives the mounting bracket 21 to move, and the mounting bracket 21 drives the X-ray generator 22 to move, thereby performing all-round X-ray inspection of the pipeline. At the same time, the drive motor 5 is started, and its output drives one of the rotating shafts 8 to rotate. The rotating shaft 8 drives the positioning plate 6, which is fixedly connected to it, to rotate. The positioning plate 6 drives the other positioning plate 6 to rotate through the cooperation of the connecting column 19 and the circular ring 18, thereby adjusting the included angle between the two positioning plates 6 to accommodate pipelines of different diameters. The cooperation of the guide rod 27 and the guide block 15 guides the movement of the mounting bracket 21, ensuring the stability of the movement of the X-ray generator 22. The protective pad 20 and anti-slip strip increase the friction between the positioning plate 6 and the pipe, preventing the pipe from sliding during the testing process. The heat dissipation window 24 and filter screen help dissipate heat from the electrical components inside the workbench 1, while preventing dust from entering.
