[0027] As can be seen from the background technology, during weld inspection, the inspection equipment and protective gear are quite heavy, which makes it difficult to fix and install the inspection tools.

[0028] To address the aforementioned issues, this application provides a weld inspection fixture that integrates functions such as fixing the inspection equipment, securing protective gear, and fixing the film onto the weld inspection fixture. This solves the problem of difficulty in fixing the inspection tools during the inspection process. Furthermore, by setting an adjustable-length main rod, a first fixing rod movable relative to the main rod, and a rotatable protective fixing structure, the weld inspection fixture's adaptability to different inspection environments is improved. This helps reduce the difficulty of adjusting the inspection angle and inspection distance, and also helps improve inspection efficiency.

[0029] The embodiments of this application will now be described in detail with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the embodiments of this application to facilitate a better understanding of the embodiments. However, the technical solutions claimed in the embodiments of this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0030] Figure 1 This is a schematic diagram of the structure of a weld inspection fixture provided in an embodiment of this application; Figure 2 This is a schematic diagram of a detection fixing structure provided in an embodiment of this application; Figure 3 This is a schematic diagram of a weld inspection fixture and the structure to be inspected provided in an embodiment of this application; Figure 4 This is a schematic diagram of the structure of a support rod provided in an embodiment of this application; Figure 5 This is a schematic diagram of another weld inspection fixture provided in an embodiment of this application; Figure 6 This is a schematic diagram of the structure of a main support frame provided in an embodiment of this application; Figure 7 This is a schematic diagram of another weld inspection fixture provided in an embodiment of this application; Figure 8 This is a schematic diagram of another weld inspection fixture provided in an embodiment of this application; Figure 9 This is a schematic diagram of another weld inspection fixture provided in an embodiment of this application; Figure 10 This is a schematic diagram of a protective fixing structure and part of a second fixing rod provided in an embodiment of this application.

[0031] refer to Figure 1The weld inspection fixture provided in this application includes: a main rod 10, the length of which is adjustable along a first direction 15; a first fixing rod 21 and a second fixing rod 22 respectively fixed to opposite ends of the main rod 10, the extension directions of the first fixing rod 21 and the second fixing rod 22 being different from the first direction 15, wherein the first fixing rod 21 is movable relative to the main rod 10 along the first direction 15; a detection fixing structure 23 disposed on the first fixing rod 21; and a protective fixing structure 24 rotatably disposed on the second fixing rod 22 relative to the second fixing rod 22.

[0032] The main body 10 is used to set up the fixing structure for the testing equipment, the fixing structure for the protective equipment, and the fixing structure for other testing tools. On the one hand, the main body 10 integrates the fixing structures for the testing equipment, the protective equipment, and other testing tools, which improves the convenience of the testing process. On the other hand, the main body 10 provides stable support for fixing the testing equipment, the protective equipment, and other testing tools, which helps improve the accuracy of the testing results and reduce the manpower waste caused by installing testing tools. The main body 10, whose length is adjustable along the first direction 15, can adapt to more testing environments, thus improving the adaptability of the weld inspection fixture to different testing environments. The first direction 15 can be any direction parallel to the length direction of the main body 10, and the specific direction of the first direction 15 can be reasonably selected according to the shape and size of the structure to be inspected, so that the main body 10 can be applied to different structures to be inspected.

[0033] In some embodiments, the main rod 10 is a structure composed of steel pipes. Steel pipes have strong pressure-bearing capacity, which helps improve the stability of the main rod 10. Furthermore, the good weldability of steel pipes helps reduce the manufacturing difficulty of the weld inspection fixture. In addition, the outer perimeter of the cross-section of the steel pipes constituting the main rod 10 in the direction perpendicular to the length of the steel pipe is circular. This shape of steel pipe is quite common, which helps reduce the difficulty of sourcing materials for the weld inspection fixture, and thus reduces the manufacturing difficulty of the weld inspection fixture. In other embodiments, the outer perimeter of the cross-section of the pipe in the direction perpendicular to the length of the pipe can also be square, rectangular, or other shapes. Furthermore, the main rod 10 can also be a structure composed of pipes made of other metal materials.

[0034] The first fixing rod 21 and the second fixing rod 22 are disposed at opposite ends of the main body rod 10. The first fixing rod 21 provides support for the detection fixing structure 23. The extension direction of the first fixing rod 21, which is different from the first direction 15, allows the detection fixing structure 23 to be moved away from the main body rod 10, which helps to avoid the main body rod 10 obstructing the radiation emitted by the detection equipment on the detection fixing structure 23. The first fixing rod 21, which is movable relative to the main body rod 10, allows the distance between the detection tool fixed on the first fixing rod 21 and the structure to be detected to be adjustable, which helps to improve the flexibility of weld inspection. The second fixing rod 22 provides support for the protective fixing structure 24. The extension direction of the second fixing rod 22, which is different from the first direction 15, allows the protective fixing structure 24 to be moved away from the main body rod 10, which helps to avoid the main body rod 10 obstructing the installation of protective equipment on the protective fixing structure 24.

[0035] refer to Figure 1 and Figure 2 The detection fixing structure 23 is located at the end of the first fixing rod 21 away from the main rod 10. The detection fixing structure 23 is used to fix the detection equipment. In some embodiments, a fixing strap 231 is provided at one end of the detection fixing structure 23 that fixes the detection equipment. The fixing strap 231 can be a structure formed by welding two steel plates at different angles. The included angle formed by the two steel plates helps to make the detection equipment mounted on the fixing strap 231 more stable, thereby improving the stability of the detection radiation emitted by the detection equipment and thus improving the accuracy of the detection results. Furthermore, within the weight-bearing range of the first fixing rod 21, the area of ​​the steel plates constituting the fixing strap 231 can be increased as much as possible. A fixing strap 231 composed of steel plates with a larger area can fix detection equipment of different sizes, which helps to improve the adaptability of the detection fixing structure 23 to different detection equipment. In some embodiments, the detection equipment fixed on the detection fixing structure 23 can be either a gamma ray machine or an X-ray machine.

[0036] The protective fixing structure 24 is located at the end of the second fixing rod 22 away from the main rod 10. The protective fixing structure 24 can be used to fix protective equipment, such as protective lead plates, and can also be used to fix the film receiving the X-ray inspection results. The protective fixing structure 24, which is rotatable relative to the second fixing rod 22, allows the angle at which the protective lead plate and the film receive X-rays to be adjustable, which helps to improve the adaptability of the weld inspection fixture to different inspection environments.

[0037] In some embodiments, reference Figure 1The main body 10 of the weld inspection fixture may further include: a main support 11; a first telescopic rod 101, which is movably fixed to the main support 11 along a first direction 15, and a first fixing rod 21 is fixed to the first telescopic rod 101; and a second telescopic rod 102, which is movably fixed to the main support 11 along a first direction 15, and a second fixing rod 22 is fixed to the second telescopic rod 102.

[0038] The main support 11 is used to fix the weld inspection fixture onto the structure to be inspected or in the inspection environment. The first telescopic rod 101 and the second telescopic rod 102 are movably fixed to opposite ends of the main support 11, allowing the length of the main rod 10 in the first direction 15 to be adjustable via the first and second telescopic rods 101 and 102. This, in turn, allows for adjustable distance between the first fixed rod 21 and the second fixed rod 22, improving the adaptability of the weld inspection fixture to different inspection environments. Furthermore, the adjustable distance between the first fixed rod 21 and the second fixed rod 22 provides sufficient space for the product to be inspected, further enhancing the adaptability of the weld inspection fixture to different working conditions.

[0039] In some embodiments, reference Figure 1 and Figure 3 The main support 11 may include: a first support 12 extending along the first direction 15, and a first telescopic rod 101 and a second telescopic rod 102 respectively movably fixed to the opposite ends of the first support 12; and a plurality of support rods 14 disposed on the first support 12, the extension direction of the support rods 14 being different from the first direction 15, and the length of the support rods 14 being adjustable.

[0040] The first bracket 12 of the main support 11 serves two purposes: firstly, it fixes the movable first telescopic rod 101 and the movable second telescopic rod 102, enabling the length of the main rod 10 to be adjustable along the first direction 15; secondly, it fixes multiple support rods 14 of the main support 11, which give the main support 11 spatial extensibility. (Refer to...) Figure 3 This design allows the main support 11 to be supported on the inner wall of the cylindrical structure 28 to be inspected, improving the adaptability of the weld inspection fixture to hole-shaped inspection environments. Furthermore, the adjustable-length support rod 14 enhances the adaptability of the main support 11 to hole-shaped inspection environments of different sizes, thereby improving the adaptability of the weld inspection fixture to various working conditions.

[0041] In some embodiments, reference Figure 1 and Figure 4The support rod 14 includes: a support rod body 141, which is fixed to the first support 12, and the end of the support rod body 141 away from the first support 12 is a tubular structure, with threads on the inner wall of the tubular structure; and a telescopic nut 142, which is disposed at the end of the support rod body 141 away from the first support 12, and the telescopic nut 142 matches the thread at the end of the support rod body 141, allowing the telescopic nut 141 to be screwed in or out of the end of the support rod body 141, thereby achieving adjustable length of the support rod 14.

[0042] In some embodiments, reference Figure 5 and Figure 6 Three support rods 14 are radially distributed in different directions with a point on the first support 12 as the center, and the extension direction of the support rods 14 is perpendicular to the first direction 15. The three support rods 14 form a Y-shaped second support 13. Due to the stability of a triangle, the Y-shaped second support 13 allows the main support 11 to be more stably fixed on the inner wall of the hole-shaped structure to be inspected, which is beneficial to improving the stability of the weld inspection fixture. In some other embodiments, the second support 13 may also include more than three support rods 14.

[0043] In some embodiments, reference Figure 1 and Figure 3 Multiple second supports 13 are fixed to the first support 12. In one example, one second support 13 includes four support rods 14. The second support 13 is X-shaped, and two second supports 13 are fixed to the first support 12 at a distance from each other. When fixing the weld inspection fixture, one second support 13 is supported on the inner wall of the hole-shaped structure 28 to be inspected, and the other second support 13 is clamped on the outside of the hole-shaped structure 28 to be inspected, which helps to improve the stability of the weld inspection fixture.

[0044] In some embodiments, reference Figure 1The first telescopic rod 101 can be sleeved on the inner or outer wall of a portion of the main support 11; the second telescopic rod 102 can be sleeved on the inner or outer wall of a portion of the main support 11. Specifically, the first telescopic rod 101 and the main support 11 can be tubular structures. The inner diameter of the tubular structure of the first telescopic rod 101 is slightly larger than the outer diameter of the portion connecting the main support 11 and the first telescopic rod 101, so that the first telescopic rod 101 is sleeved on the outer wall of the main support 11, thereby allowing the first telescopic rod 101 to be movably mounted on the main support 11 along the first direction 15, which is beneficial to improving the adaptability of the weld inspection fixture to different working conditions. Furthermore, the outer diameter of the second telescopic rod 102 is slightly smaller than the inner diameter of the tubular structure connecting the main support 11 and the second telescopic rod 102, so that the second telescopic rod 102 is sleeved on the inner wall of the main support 11, thereby allowing the second telescopic rod 102 to be movably mounted on the main support 11 along the first direction 15, which is beneficial to improving the adaptability of the weld inspection fixture to different working conditions. In other embodiments, the first telescopic rod 101, the second telescopic rod 102, and the main support 11 can all be tubular structures, and while ensuring that the second telescopic rod 102 and the first telescopic rod 101 are movable relative to the main support 11, refer to Figure 7 Both the first telescopic rod 101 and the second telescopic rod 102 can be fitted onto the inner side wall of the main support 11. Alternatively, refer to... Figure 8 Both the first telescopic rod 101 and the second telescopic rod 102 are sleeved on the outer side wall of the main support 11. Alternatively, the first telescopic rod 101 may be sleeved on the inner side wall of a portion of the main support 11; and the second telescopic rod 102 may be sleeved on the outer side wall of a portion of the main support 11.

[0045] In some embodiments, reference Figure 1The first telescopic rod 101 may be provided with several threaded holes penetrating the side wall of the first telescopic rod 101 and nuts that match the threaded holes. The nuts are used to fix the first telescopic rod 101 to the main support 11. A threaded hole is provided at the position where the first telescopic rod 101 connects to the main support 11, and the threaded hole penetrates the side wall of the tubular structure of the first telescopic rod 101. The nut that matches the threaded hole can be screwed into the threaded hole, contacting and pressing the main support 11, which is sleeved on the inner side wall of the first telescopic rod 101, so that the main support 11 presses the first telescopic rod 101 tightly, thereby making the first telescopic rod 101 stably fixed on the main support 11. When adjusting the position of the detection fixing structure 23 on the first fixing rod 21 in the first direction 15, the nut in the screw hole can be unscrewed, so that the first telescopic rod 101 moves relative to the main support 11 in the first direction 15. After adjusting the length of the main rod 10 in the first direction 15 to a suitable length, the nut is screwed into the screw hole, thereby fixing the first telescopic rod 101 and the main support 11, realizing the movement of the detection fixing structure 23 relative to the main support 11 in the first direction 15, which is beneficial to improving the adaptability of the weld inspection fixture to different working conditions.

[0046] In some embodiments, the number of screw holes for fixing the first telescopic rod 101 to the main support 11 can be at least two, and correspondingly, the number of nuts matching the screw holes can be at least two. In one example, the first telescopic rod 101 is provided with two screw holes and two nuts matching the screw holes. Compared to fixing the first telescopic rod 101 to the main support 11 with one screw hole and one nut, providing two screw holes and two nuts on the first telescopic rod 101 is beneficial to improving the fixing stability of the first telescopic rod 101 and the main support 11.

[0047] In some embodiments, reference Figure 1 The main support 11 may be provided with several screw holes penetrating the side wall of the main support 11 and nuts that match the screw holes. The nuts are used to fix the second telescopic rod 102 to the main support 11.

[0048] A screw hole is provided at the connection position between the main support 11 and the second telescopic rod 102, and the screw hole penetrates the side wall of the tubular structure of the main support 11. A nut matching the screw hole can be screwed into the screw hole, contacting and pressing the second telescopic rod 102, which is sleeved on the inner side wall of the main support 11, so that the second telescopic rod 102 presses tightly against the main support 11, thereby making the main support 11 stably fixed on the second telescopic rod 102. When adjusting the position of the protective fixing structure 24 on the second fixing rod 22 in the first direction 15, the nut in the screw hole can be unscrewed, so that the second telescopic rod 102 moves relative to the main support 11 in the first direction 15. After adjusting the length of the main rod 10 in the first direction 15 to a suitable length, the nut is screwed into the screw hole, thereby fixing the main support 11 and the second telescopic rod 102, realizing the movement of the protective fixing structure 24 relative to the main support 11 in the first direction 15, which is beneficial to improving the adaptability of the weld inspection fixture to different working conditions.

[0049] In some embodiments, reference Figure 9 The number of screw holes for fixing the second telescopic rod 102 to the main support 11 can be one, and correspondingly, the number of nuts matching the screw holes can be one. Since the outer diameter of the second telescopic rod 102, which is fitted inside the main support 11, is small, one screw hole and one nut are sufficient to stably fix the second telescopic rod 102 to the main support 11. This helps reduce the complexity of the weld inspection fixture, and thus reduces the manufacturing difficulty of the weld inspection fixture. In other embodiments, refer to... Figure 1 The number of screw holes that fix the second telescopic rod 102 to the main support 11 can be multiple, and correspondingly, the number of nuts that match the screw holes can also be multiple.

[0050] In some embodiments, reference Figure 9 The detection fixing structure 23 is movable relative to the first fixing rod 21 along the extension direction of the first fixing rod 21. The movable detection fixing structure 23 relative to the first fixing rod 21 allows for angle adjustment between the detection equipment and the structure to be inspected, which improves the flexibility of weld inspection.

[0051] In some embodiments, reference Figure 9 The detection fixing structure 23 can be sleeved on the outer side wall of part of the first fixing rod 21; the detection fixing structure 23 is provided with a screw hole penetrating the side wall of the detection fixing structure 23 and a nut that matches the screw hole, and the nut is used to fix the detection fixing structure 23 and the first fixing rod 21.

[0052] The connection between the detection fixing structure 23 and the first fixing rod 21 is a tubular structure. The inner diameter of the tubular structure of the first fixing rod 21 is slightly larger than the outer diameter of the connection between the first fixing rod 21 and the detection fixing structure 23, so that the detection fixing structure 23 is fitted onto the outer side wall of part of the first fixing rod 21. Furthermore, a screw hole and a nut are provided at the connection between the detection fixing structure 23 and the first fixing rod 21. The screw hole penetrates the side wall of the tubular structure of the detection fixing structure 23, and the nut, matching the screw hole, can be screwed into the screw hole, contacting and pressing the first fixing rod 21 fitted onto the inner side wall of the detection fixing structure 23. This causes the first fixing rod 21 to press firmly against the detection fixing structure 23, thereby ensuring that the detection fixing structure 23 is stably fixed onto the first fixing rod 21. When adjusting the position of the detection fixing structure 23 in the extending direction of the first fixing rod 21, the nut in the screw hole can be unscrewed, allowing the detection fixing structure 23 to move relative to the first fixing rod 21 in the extending direction of the first fixing rod 21. After adjusting the detection fixing structure 23 to a suitable position, the nut is screwed into the screw hole to fix the detection fixing structure 23 and the first fixing rod 21. This allows the detection fixing structure 23 to be movably mounted on the first fixing rod 21, enabling angle adjustment between the detection equipment and the structure to be detected, which improves the flexibility of weld inspection. In other embodiments, the connection between the first fixing rod 21 and the detection fixing structure 23 is a tubular structure. While ensuring that the detection fixing structure 23 is movable relative to the first fixing rod 21 in the extending direction of the first fixing rod 21, a portion of the detection fixing structure 23 can also be sleeved on a portion of the inner wall of the first fixing rod 21.

[0053] In some embodiments, reference Figure 3 and Figure 10 The second fixing rod 22 may be provided with a connector 221, and the protective fixing structure 24 is provided with a locking groove 241. The locking groove 241 is rotatably sleeved on the connector 221 so that the protective fixing structure 24 is rotatably connected to the second fixing rod 22. The locking groove 241 and the connector 221 include: a screw hole penetrating the locking groove 241 and penetrating the side wall of the connector 221; and a nut that matches the screw hole. The nut is used to fix the protective fixing structure 24 and the second fixing rod 22.

[0054] The engaging groove 241 on the protective fixing structure 24 is rotatably mounted on the connector 221 of the second fixing rod 22, allowing the protective fixing structure 24 to rotate relative to the second fixing rod 22. The protective fixing structure 24 is fixed to the second fixing rod 22 via a threaded hole and a nut that penetrate the engaging groove 241 and the side wall of the connector 221. The protective fixing structure 24 also includes a gasket 242, which is used to mount the protective lead plate 25 and the base plate 26. After the radiation emitted by the testing equipment 29 passes through the fillet weld 27 on the structure to be tested 28, the rotatable protective fixing structure 24 allows the protective lead plate 25 and the base plate 26 to receive the testing radiation emitted by the testing equipment 29 at different angles, thus improving the flexibility of weld inspection.

[0055] refer to Figure 3 In some embodiments, the second fixing rod 22 is further provided with a sleeve 222, and the sleeve is movable relative to the main rod portion 10 along the extension direction of the second fixing rod 22. A connector 221 is provided on the sleeve 222, which can be fitted onto a portion of the outer wall of the second fixing rod 22. The sleeve 222 has several threaded holes penetrating the side wall of the sleeve 222 and nuts matching the threaded holes. The nuts are used to fix the sleeve 222 and the second fixing rod 22. The movable sleeve 222 allows the protective fixing structure 24 to move relative to the main rod portion 10 along the extension direction of the second fixing rod 22, and allows the protective lead plate 25 and the base plate 26 on the protective fixing structure 24 to move relative to the main rod portion 10. This allows the protective lead plate 25 and the base plate 26 to receive the detection radiation emitted by the detection device 29 at different positions, which is beneficial to improving the flexibility of weld inspection. It should be noted that in other embodiments, the sleeve 222 can also be fitted onto a portion of the inner wall of the second fixing rod 22.

[0056] In some embodiments, reference Figure 9 An angle gauge 25 and a distance gauge 26 may be provided at the end of the detection fixing structure 23 away from the main rod 10. The angle gauge 25 is used to measure the angle between the detection equipment and the weld to be tested, and the distance gauge 26 is used to measure the distance between the detection equipment and the weld to be tested. The angle and distance between the detection equipment and the weld to be tested can provide data support for the evaluation of the weld inspection results, which is conducive to obtaining more accurate inspection data and thus improving the accuracy of the inspection results.

[0057] The weld inspection fixture provided in the above embodiments integrates the functions of fixing the inspection equipment, the protective equipment, and the film on the weld inspection fixture by setting up the inspection fixing structure 23 and the protective fixing structure 24, thus solving the problem of fixing the inspection tool during the inspection process. The adjustable length main rod 10, the first fixing rod 21 movable relative to the main rod 10, and the rotatable protective fixing structure 24 help reduce the difficulty of adjusting the inspection angle and inspection distance. The different extension directions of the first fixing rod 21 and the second fixing rod 22 from the first direction 15 facilitate the setting of the unobstructed opposite inspection fixing structure 23 and the protective fixing structure 24, so that there is sufficient space between the inspection fixing structure 23 and the protective fixing structure 24 to set the product to be inspected. The angle gauge 25 and the distance gauge 26 set on the inspection fixing structure 23 help improve the accuracy of the inspection results. In summary, the weld inspection fixture provided in this application embodiment helps to solve the problem of fixing the inspection tool, reduces the difficulty of weld inspection operation, and improves the accuracy of the inspection results.
