[0046] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0048] Combination Figure 1 and Figure 2 As shown, this utility model embodiment provides a rotary detection mechanism, which includes a base 1, a rotating component 2, and a detection component 3; the base 1 has a central part for concentric alignment of the tube body 4 to be tested; the rotating component 2 is movably mounted on the base 1 and can rotate around the central part in the forward or reverse direction; the detection component 3 is movably mounted in the rotating component 2 and can rotate synchronously with the rotating component 2 and move relative to it along the extension direction of the rotating component 2 itself;

[0049] The detection component 3 has a detection port 31 for inserting into one end of the tube wall of the tube body 4 to be tested, and the detection port 31 can rotate with the detection component 3 in relation to the tube body 4 to be tested; the detection component 3 can collect image information of the inner wall and outer wall of the tube body 4 to be tested through the detection port 31.

[0050] The rotary inspection mechanism provided in this embodiment of the utility model can be specifically applied to the inspection of the welding quality of formed pipe sections. Taking this as an example, its working process is described in detail.

[0051] In practical use, the rotary testing mechanism first aligns the welded end of the pipe body 4 to be tested with the center of the base 1, and inserts the pipe wall of the welded end of the pipe body 4 into the testing port 31 of the testing component 3. Then, the position of the testing component 3 in the extension direction of the rotating component 2 is adjusted so that the testing port 31 in the testing component 3 has an appropriate distance from the inner and outer walls of the welded end of the pipe body 4. Finally, the rotating component 2 is rotated around the center of the base 1 in either the forward or reverse direction, so that the testing component 3 can rotate synchronously with the rotating component 2. In this way, the testing component 3 can collect image information of the inner and outer walls of the pipe body 4 in a circumferential manner, thereby accurately and efficiently testing the welding quality of the welded end of the pipe body 4.

[0052] Moreover, when it is necessary to inspect the welded ends of the cross-section of the pipe body 4 with different diameters, it is only necessary to adjust the position of the detection element 3 in the extension direction of the rotating element 2 so that the detection element 3 is adapted to the radius of the pipe body 4 with the actual rotation radius of the rotating element 2. Therefore, the rotary detection mechanism provided by this utility model embodiment also has extremely high universality and adaptability, and can also be applied to the inspection of the cross-section welding quality of large-diameter pipes.

[0053] In summary, compared with the existing methods of manually measuring with calipers and visually inspecting the welding quality of the pipe cross-section, the rotary inspection mechanism provided in this embodiment of the utility model has the advantages of high inspection efficiency, accurate inspection results, retention of inspection results, and universal adaptability to inspect pipes of different diameters.

[0054] In one embodiment, the detection component 3 includes a housing 32 and a camera 33; a detection port 31 is formed by a recess in one side wall of the housing 32; the camera 33 is disposed in the housing 32, and the lens of the camera 33 is correspondingly disposed with the detection port 31, and can take pictures by light entering through the detection port 31.

[0055] Specifically, in combination Figure 4To further explain in detail, the detection component 3 is specifically configured to include a housing 32 and a camera 33. One side wall of the housing 32 is recessed to form a detection port 31, and the camera 33 is set inside the housing 32. In this way, the lens of the camera 33 can be set to correspond with the detection port 31, and light can enter through the detection port 31 to take pictures. When the detection component 3 rotates synchronously with the rotating component 2, the detection port 31 can move circumferentially to the wall of the tube body 4 to be tested. In this way, the camera 33 can capture or record the image information of the inner wall, outer wall and end face wall of the welded end of the tube body 4 to be tested. The maintenance personnel can accurately judge the welding quality of the welded port of the tube body 4 to be tested based on the photos taken by the camera 33 or the videos recorded by the camera 33.

[0056] The specific setup of the aforementioned testing component 3 has the advantages of simple structure and enabling maintenance personnel to accurately and efficiently judge the welding quality of the pipe end based on photos or videos.

[0057] Of course, the aforementioned camera 33 can also be an AI vision camera with a higher level of intelligence, which can automatically judge the welding quality of the pipe port based on the photos or videos taken by AI vision.

[0058] In one embodiment, the detection port 31 includes a first port surface 311, a second port surface 312, and a third port surface 313 connected vertically in sequence; the first port surface 311, the second port surface 312, and the third port surface 313 together form a rectangular opening recessed in the housing 32; the camera 33 includes an inner wall camera 331 corresponding to the first port surface 311, an end face camera 332 corresponding to the second port surface 312, and an outer wall camera 333 corresponding to the third port surface 313.

[0059] Specifically, in combination Figure 4 In further detail, the detection port 31 specifically includes a first port surface 311, a second port surface 312, and a third port surface 313 connected vertically in sequence. The first port surface 311, the second port surface 312, and the third port surface 313 can all be set as transparent, colorless, and light-transmitting surfaces, or each can have a light-entry window. In this way, the inner wall camera 331 corresponding to the first port surface 311, the end face camera 332 corresponding to the second port surface 312, and the outer wall camera 333 corresponding to the third port surface 313 can clearly capture images or video information of the inner wall, end face, and outer wall of the welded pipe end of the pipe body 4 under test, so that maintenance personnel can more accurately judge the welding quality of the welded pipe end.

[0060] In one embodiment, the rotating component 2 includes a rotating plate 21, an arc-shaped slider 22, and a drive motor 23; one end of the rotating plate 21 is movably connected to the center of the base 1; the arc-shaped slider 22 is fixedly disposed at the other end of the rotating plate 21; the drive motor 23 is disposed in the arc-shaped slider 22 and can drive the arc-shaped slider 22 and the rotating plate 21 to rotate together around the center of the base 1 in the forward or reverse direction.

[0061] Specifically, in combination Figure 2 In further detail, the rotating component 2 is specifically configured to include a rotating plate 21, an arc-shaped slider 22, and a drive motor 23. One end of the rotating plate 21 is movably connected to the center of the base 1. The arc-shaped slider 22 is fixedly mounted on the other end of the rotating plate 21. The drive motor 23 is located in the arc-shaped slider 22. In this way, the drive motor 23 can drive the arc-shaped slider 22 and the rotating plate 21 to rotate together around the center of the base 1 in either the forward or reverse direction. This causes the detection component 3 to rotate together with the rotating component 2 around the center of the base 1 in either the forward or reverse direction, thereby realizing the reverse imaging of the inner wall, end face, and outer wall of the welded pipe end of the tube body 4 to be tested.

[0062] The specific arrangement of the rotating component 2 described above has the advantages of simple structure and the ability to sensitively and efficiently drive the detection component 3 to rotate around the center of the base 1 together with the rotating component 2.

[0063] Of course, the rotating component 2 mentioned above can also be configured in other structural forms. For example, the drive motor 23 mentioned above can be replaced with a manual rocker arm, which can also achieve the function of driving the rotating plate 21 to rotate around the center of the base 1.

[0064] In one embodiment, a central bearing 12 is provided in the center of the base 1; one end of the rotating plate 21 is movably connected to the center of the base 1 through the central bearing 12.

[0065] Specifically, in combination Figure 3 In further detail, a central bearing 12 is provided in the center of the base 1, and one end of the rotating plate 21 is connected to the central bearing 12. When the rotating plate 21 rotates and the base 1 rotates in the center, the central bearing 12 can be driven accordingly. On the one hand, this can greatly reduce the resistance when the rotating plate 21 rotates and improve the smoothness of rotation. On the other hand, the central bearing 12 can also fix the rotation center of the rotating plate 21, thereby ensuring that the detection piece 3 installed in the rotating plate 21 rotates out a standard circular trajectory.

[0066] In one embodiment, the base 1 is further provided with a transmission gear ring 11 concentric with the center; the output shaft of the drive motor 23 is provided with a transmission gear 231 that meshes with the transmission gear ring 11; the drive motor 23 can drive the transmission gear 231 to rotate and move along the transmission gear ring 11.

[0067] Specifically, in combination Figure 1 and Figure 2 In further detail, a transmission gear ring 11 concentric with the center is provided in the base 1, and a transmission gear 231 meshing with the transmission gear ring 11 is provided in the output shaft of the drive motor 23. In this way, when the drive motor 23 drives the transmission gear 231 to rotate, the transmission gear 231 can rotate on its own axis and move in a circle along the transmission gear ring 11 while meshing, thereby realizing the controllable driving of the rotating plate 21 and the detection piece 3 to rotate in a circle around the center of the base 1.

[0068] The transmission configuration of the aforementioned transmission ring 11 and transmission gear 231 has the advantages of stable transmission structure and the ability to control the output angle of the drive motor 23 to precisely adjust the rotation angle position of the detection piece 3 around the center of the base 1.

[0069] In one embodiment, an annular slide rail 111 is also provided on the side of the transmission gear ring 11 facing away from the base 1; a sliding roller 221 that slides in cooperation with the annular slide rail 111 is provided on the side of the arc slider 22 facing the transmission gear ring 11.

[0070] Specifically, in combination Figure 1 and Figure 2 In further detail, an annular slide rail 111 is provided on the side of the transmission gear ring 11 facing away from the base 1, and a sliding roller 221 that slides and engages with the annular slide rail 111 is provided on the side of the arc slider 22 facing the transmission gear ring 11. In this way, the arc slider 22 can slide and engage with the annular slide rail 111 through the sliding roller 221. On the one hand, it can support the arc slider 22 more stably, and on the other hand, it can reduce the rotational resistance when the arc slider 22 and the rotating plate 21 rotate around the base 1 at the center.

[0071] In one embodiment, the rotating plate 21 is provided with an adjustment rail 211 extending along its own direction on the side opposite to the base 1; the detection element 3 is disposed in the adjustment rail 211 and can be reciprocated and adjusted along the adjustment rail 211.

[0072] Specifically, in combination Figure 1 In further detail, an adjustment rail 211 extending along its own extension direction is provided on the side of the rotating plate 21 facing away from the base 1. The detection element 3 is disposed in the adjustment rail 211 and can be adjusted and slid along the adjustment rail 211. Specifically, the detection element 3 can be adjusted and slidably disposed in the adjustment rail 211 by means of clamping parts or screw parts. This not only ensures that the detection element 3 is stably and firmly installed in the rotating plate 21, but also allows for adjustment of the rotation radius of the detection element 3 by sliding adjustment of its position on the adjustment rail 211.

[0073] In one embodiment, a magnetic suction member is provided on the side of the rotating plate 21 facing away from the base 1, extending along its own direction; the detection member 3 can be fixedly mounted on the rotating plate 21 by the magnetic suction member.

[0074] Of course, a magnetic suction element is provided on the side of the rotating plate 21 facing away from the base 1, extending along its own direction, and the detection element 3 can be fixedly mounted on the rotating plate 21 by the magnetic suction element. This can also achieve stable and secure installation of the detection element 3 in the rotating plate 21. Moreover, when it is necessary to adjust the rotation radius of the detection element 3, it is only necessary to manually push the position of the detection element 3 on the adjustment rail 211, or to automatically adjust the position of the detection element 3 in the rotating plate 21 by the linear drive module connected to the detection element 3.

[0075] In one embodiment, the corner of the base 1 is also provided with mounting holes, through which the base 1 can be installed horizontally or vertically.

[0076] Specifically, in combination Figure 1 In further detail, mounting holes can be provided at the four corners of the base 1. These mounting holes can be threaded holes, pin holes, etc., so that the base 1 can be fixedly installed in the horizontal or vertical plane by means of screw connection or pin connection.

[0077] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0078] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
