Due to diverse site conditions, it is often difficult to find an ideal fixed position for the gamma source guide (hereinafter referred to as the source guide). The position must be fixed according to the specific site conditions. The specifications, materials, and distribution of the pipes vary, making it inconvenient to adjust the position of the gamma source guide, resulting in inconsistencies in the incident angle and spacing, which in turn affects the quality of the radiographs. Utility Model Content

[0003] To address the aforementioned issues and achieve a fixed incident angle and focal length during gamma-ray imaging, while also being applicable to various pipeline inspections, this application provides a gamma-ray elliptical imaging fixture.

[0004] The gamma-ray source imaging elliptical imaging fixture provided in this application adopts the following technical solution.

[0005] A gamma-ray source elliptical imaging fixture includes: a fixture body, the fixture body including a top frame for placing a source conduit, the bottom of the top frame being provided with a movable frame for connecting to the conduit, the movable frame and the top frame being slidably connected up and down by a movable component;

[0006] The movable component includes a first sliding straight slot at the bottom of the top frame and a second sliding straight slot on the movable frame, and the first sliding straight slot and the second sliding straight slot are connected by bolts.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] The following is in conjunction with the appendix Figures 1 to 6 This application will be described in further detail.

[0041] This application discloses a gamma-ray source elliptical imaging fixture.

[0042] Example 1

[0043] Reference Figures 1 to 3 A gamma-ray source elliptical imaging fixture includes: a fixture body, a top frame for placing a source guide tube 1, and a movable frame 2 for connecting to a pipe array 3 at the bottom of the top frame. The movable frame 2 and the top frame are slidably connected vertically via a movable component. The source guide tube 1 is placed on the top frame, and the movable frame 2 is connected to the pipe array 3. Through the movable component, the top frame and the movable frame 2 are slidably connected vertically, thereby allowing adjustment of the height of the source guide tube 1, the distance between the weld seams on the source guide tube 1 and the pipe array 3, and the incident angle and focal length.

[0044] The tooling body can be made of sheet metal.

[0045] The top frame includes the installation of the top frame and the support of the top plate.

[0046] The mounting frame includes two spaced-ahead mounting plates 4, each with a straight mounting slot 5. The source conduit 1 is inserted through and into the straight mounting slots 5 on both mounting plates 4. The straight mounting slots 5 allow the source conduit 1 to be fixed to the mounting frame and move along the slot direction to adjust its position. The two mounting plates 4 further enhance the stability of the source conduit 1 after insertion into the straight mounting slots 5 and improve its stability during movement along the slot direction.

[0047] Clamping bolts 6 are installed in the mounting slots 5 on both sides of the source conduit 1. Clamping blocks 7 are installed on the clamping bolts 6 between the two mounting plates 4. The side of the clamping block 7 closest to the source conduit 1 is arc-shaped. By adjusting the position of the clamping bolts 6 in the mounting slots 5, they can abut against the source conduit 1. Tightening the clamping bolts 6 can fix their position, thereby limiting the source conduit 1 from the side and restricting its movement within the mounting slots 5, thus fixing the position of the source conduit 1. The clamping blocks 7, when the clamping bolts 6 are close to the source conduit 1, allow the arc-shaped side of the clamping block 7 to better engage with the source conduit 1, clamping it and fixing its position, thus achieving a fixed incident angle and a fixed focal length.

[0048] The supporting top plate 8 is located at the bottom of both sides of the mounting frame.

[0049] The movable component includes a first sliding straight slot 9 on the supporting top plate 8 and a second sliding straight slot 10 on the movable frame 2, which are connected by bolts. The first sliding straight slot 9 on the supporting top plate 8 and the second sliding straight slot 10 on the movable frame 2, connected by bolts, allow the movable frame 2 and the supporting top plate 8 to slide along the slot direction, achieving a vertical sliding connection between them. This connection method is simple, reliable, and easy to adjust.

[0050] The bottom of the first sliding straight groove 9 on the movable frame 2 is also provided with a third sliding straight groove 11. The sliding clamp 12 is connected to the third sliding straight groove 11 by bolts. The bottom end of the movable frame 2 is bent, which can be bent at 90 degrees to form fixed clamps 13 that are spaced apart from the sliding clamps 12. With the setting of the third sliding straight groove 11, the sliding clamps 12 can be fixed to the movable frame 2 by bolts, and loosening the bolts can allow the sliding clamps 12 to slide along the direction of the third sliding straight groove 11. Adjusting the distance between the sliding clamps 12 and the fixed clamps 13 can achieve clamping of the pipe 3. The method of clamping the pipe 3 is simple to operate and reliable in connection.

[0051] Example 2

[0052] Reference Figure 4A gamma-ray source elliptical imaging fixture is provided, comprising all the contents of Embodiment 1, except that it does not use fastening bolts and clamping blocks 7. Instead, wrapping material 14 is provided on both sides of the source guide tube 1 on the top frame to tightly wrap the source guide tube 1 within the mounting straight slot 5. The wrapping material 14 can be tape, rope, etc., for the purpose of tightly wrapping the source guide tube 1. By providing wrapping material 14 on both sides of the source guide tube 1, the source guide tube 1 can be tightly wrapped on the top frame, thereby fixing the position of the source guide tube 1 and achieving a fixed incident angle and a fixed focal length.

[0053] Example 3

[0054] Reference Figures 5 to 6 A gamma-ray source elliptical imaging fixture is provided, comprising all the contents of Embodiment 1, except that it does not employ a clamping method for the tube array 3. When the diameter of the tube array 3 is large, the sliding range of the sliding clamp 12 is limited, thus limiting the clamping range and making a clamping method inconvenient. A magnet 15 is provided at the bottom of the movable frame 2 for magnetic attraction with the tube array 3, connecting to the tube array 3 via magnetic attraction. A magnet fixing hole is provided at the bottom of the movable frame 2, with the magnet 15 and magnet fixing plate 16 distributed on both sides of the movable frame 2, and the magnet 15, movable frame 2, and magnet fixing plate 16 connected by bolts. The magnet 15 is fixed to the movable frame 2 by bolts, making the installation simple and reliable. This allows for magnetic attraction between the movable frame 2 and the tube array 3, and the magnetic connection method is simple to operate, reliable, and unaffected by the size of the tube array 3.

[0055] The method of clamping the pipe 3 and the method of magnetic attraction with the pipe 3 can be freely selected, and the appropriate method can be selected according to different site conditions.
