Detailed Implementation

[0017] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. The terms "first," "second," etc., used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] This application provides an adjustment device; please refer to [link / reference]. Figure 1 and Figure 2 The adjustment device 100 includes a support 1, a base plate 2, and an adjustment device 3. The base plate 2 is mounted on the support 1 and has a reference hole 2a. The adjustment device 3 includes an adjustment assembly 31 and a support plate 32 with a reference hole 32a. The adjustment assembly 31 is mounted on the support 1. The reference hole 32a and the reference hole 2a are used to pass through an acceleration tube. The upper surface of the support plate 32 is used to support the focusing coil of the acceleration tube. The adjustment assembly 31 can adjust the focusing coil to move in the left-right and front-back directions so that the focusing coil is coaxial with the reference hole 2a.

[0020] This application provides an adjustment device 100, which, by setting a substrate 2, can provide a reference surface for the focusing coil; by forming a reference hole 2a on the substrate 2, a reference can be provided for adjusting the position of the focusing coil. By setting a support plate 32, a stable support can be provided for the focusing coil to avoid unstable installation of the focusing coil affecting the beam convergence. By forming a reference hole 32a on the support plate 32, the accelerating tube passes through the reference hole 32a and the reference hole 2a, and then the focusing coil is adjusted to move in the front-back direction and left-right direction by the adjustment component 31, so that the focusing coil is coaxial with the reference hole 2a. In this way, the beam in the accelerating tube can move stably downward, the beam convergence ability is good, the high installation and positioning accuracy of the focusing coil in the accelerator is met, and the beam quality is high.

[0021] For example, in one embodiment, the adjustment device 100 can be used for the installation and commissioning of the focusing coil of the accelerator. In this way, by adjusting the movement of the focusing coil through the adjustment component 31, the installation and commissioning time can be saved and the labor intensity of the operators can be reduced.

[0022] For example, in one embodiment, the accelerator may be a high-power irradiation accelerator.

[0023] As an example, in one embodiment, please refer to Figure 1 The support 1 includes four columns 11 and four connecting plates 12. The four columns 11 are spaced apart in the front-back and left-right directions. Each connecting plate 12 is connected to the top surface of two adjacent columns 11, so that the support 1 is roughly rectangular.

[0024] In one embodiment, the adjustment component 31 can adjust the support plate 32 to move in the left-right and front-back directions so that the reference hole 32a is coaxial with the reference hole 2a. In this way, by adjusting the support plate 32 to move in the left-right and front-back directions, it can be ensured that the axis of the accelerating tube extends vertically in the direction of the direction of the beam, so as to avoid the beam from colliding with the tube wall of the accelerating tube when it moves downward, thereby improving the focusing performance of the beam.

[0025] In one embodiment, please refer to Figure 1 The adjustment device 3 is located above the base plate 2. For example, the base plate 2 can be connected to the bottom surface of the four columns 11, which has strong vibration resistance to reduce the change of reference due to vibration or movement.

[0026] For example, in one embodiment, the connection between the substrate 2 and the column 11 can be screwed or welded, which can improve the connection strength between the substrate 2 and the support 1 to stably provide a reference.

[0027] In one embodiment, please refer to Figure 1The number of adjustment devices 3 is multiple, and the multiple adjustment devices 3 are arranged at intervals along the vertical direction. For example, the number of adjustment devices 3 is not limited. For example, there can be two adjustment devices 3, which are arranged at intervals along the vertical direction. In this way, on the one hand, by setting multiple adjustment devices 3 to limit the acceleration tube in segments, the swaying situation is reduced; on the other hand, multiple focusing coils can be supported and adjusted along the vertical direction, so that the beam convergence effect is better, the density is higher, and the beam penetration ability is stronger.

[0028] In one embodiment, please refer to Figure 2 The support plate 32 has a first adjustment hole 32b extending in the front-rear direction. The adjustment assembly 31 includes a positioning block 311 and an adjustment member 312. The positioning block 311 is connected to the bracket 1 and has a second adjustment hole 311a extending in the left-right direction. The adjustment member 312 includes a connecting stud 3121, a first adjustment bolt 3122, and a second adjustment bolt 3123. The connecting stud 3121 passes through the first adjustment hole 32b and the second adjustment hole 311a. The first adjustment bolt 3122 passes through the positioning block 311 in the left-right direction and abuts against the connecting stud 3121. The first adjustment bolt 3122 rotates to push the connecting stud 3121 to move the support plate 32 in the left-right direction. For example, the connecting stud 3121 includes an abutment section 3121a and two threaded sections 3121b. The two threaded sections 3121b are respectively disposed at both ends of the abutment section 3121a in the vertical direction. The projected area of ​​the threaded section 3121b in the vertical direction is located within the projected area of ​​the abutment section 3121a. The abutment section 3121a abuts above the second adjusting hole 311a. The positioning block 311 has a threaded hole. The threaded section 3121b located below passes through the second adjusting hole 311a and abuts against the first adjusting bolt 3122. Thus, by rotating the first adjusting bolt 3122, the support plate 32 is pushed to move in the left and right direction through the threaded engagement with the threaded hole.

[0029] The second adjusting bolt 3123 passes through the support plate 32 in the front-to-back direction and abuts against the connecting stud 3121. Rotating the second adjusting bolt 3123 pushes the connecting stud 3121, causing the support plate 32 to move in the front-to-back direction. For example, the support plate 32 has an upwardly folded edge A with a threaded hole extending in the front-to-back direction. The upper threaded section 3121b passes through the first adjusting hole 32b and abuts against the second adjusting bolt 3123. Thus, rotating the second adjusting bolt 3123, through its threaded engagement with the threaded hole, pushes the support plate 32 to move in the front-to-back direction.

[0030] In this embodiment, on the one hand, the support plate 32 can be pushed by manually turning the first adjusting bolt 3122 and the second adjusting bolt 3123, so that the reference hole 32a and the reference hole 2a are coaxially aligned, which is convenient and efficient. On the other hand, the position is adjusted by means of thread engagement, which has high control accuracy of the pushing stroke and is stable and reliable. Furthermore, the use of connecting studs 3121, the first adjusting bolt 3122 and the second adjusting bolt 3123 makes installation and disassembly convenient and easy to replace.

[0031] In one embodiment, the adjustment assembly 31 includes three locking nuts. One locking nut is located above the support plate 32, and another below the positioning block 311. A locking nut is located between the support plate 32 and the positioning block 311. A connecting stud 3121 is threadedly engaged with the three locking nuts. Here, when the support plate 32 needs to be adjusted vertically, the two locking nuts above and below the support plate 32 can be adjusted to engage with the threaded section 3121b located above, thus fixing the support plate 32 between the two locking nuts. This ensures the relative height with the substrate 2, thereby changing the focusing intensity of the magnetic field generated by the focusing coil on the beam and meeting the beam emission requirements. The locking nut located below the positioning block 311 engages with the abutment section 3121a and locks onto the positioning block 311, providing support for the support plate 32.

[0032] In one embodiment, please refer to Figure 1 The number of adjustment components 31 is multiple, and the multiple adjustment components 31 are arranged at intervals around the periphery of the support plate 32. For example, the number of adjustment components 31 is not limited, for example, there can be 4. The 4 adjustment components 31 can be arranged at the four corners of the support plate 32. In this way, the support plate 32 can be stably pushed to move in the front-back direction, left-right direction and up-down direction, and the support plate 32 can be stably supported.

[0033] In one embodiment, please refer to Figure 2 The positioning block 311 includes a fixing part 3111, a connecting part 3112, and a bending part 3113. The fixing part 3111 and the bending part 3113 are respectively connected to the two opposite ends of the connecting part 3112 in the left-right direction. The fixing part 3111 is connected to the bracket 1. The connecting part 3112 forms a second adjusting hole 311a. The first adjusting bolt 3122 passes through the bending part 3113 in the left-right direction. For example, the fixing part 3111 is fixedly mounted on the bracket 1. One end of the connecting part 3112 is fixedly mounted on the fixing part 3111. The other end of the connecting part 3112 extends in the left-right direction and connects to one end of the bending part 3113. The other end of the bending part 3113 extends downward so that the entire positioning block 311 is approximately U-shaped. In this way, the first adjusting bolt 3122 can better push the connecting stud 3121 to drive the support plate 32 to move.

[0034] For example, in one embodiment, the positioning block 311 and the bracket 1 can be connected by screws or bolts. For instance, the fixing part 3111 has a plurality of first mounting holes, and the column 11 has a plurality of second mounting holes. Both the first mounting holes and the second mounting holes are bolt holes. The bolts or screws pass through the first mounting holes and are threadedly connected to the second mounting holes, thus providing stable support for the focusing coil.

[0035] In one embodiment, please refer to Figure 1 and Figure 2 The reference hole 2a is located at the geometric center of the substrate 2, and the reference hole 32a is located at the geometric center of the support plate 32. This arrangement provides two advantages: firstly, setting the reference hole 2a and the reference hole 32a at the geometric center provides higher positioning accuracy because the center of the support plate 32 and the substrate 2 is a stable position that is easy to determine and measure, helping to ensure the accuracy of the position and relative position of other holes such as the first adjustment hole 32b and parts such as the adjustment assembly 31; secondly, it simplifies operation. By setting the reference hole 2a at the geometric center of the substrate 2 and the reference hole 32a at the geometric center of the support plate 32, the operator only needs to align the support plate 32 and the substrate 2 and fix them on the bracket 1, thus aligning the reference hole 32a with the reference hole 2a.

[0036] In one embodiment, please refer to Figure 1 and Figure 2 The adjusting assembly 31 includes a third adjusting bolt 313, which is threadedly engaged with the support plate 32. The third adjusting bolt 313 is used to abut against the focusing coil, causing the focusing coil to move in the left-right and front-back directions. In this way, by adjusting the position of the focusing coil through the threaded engagement of the third adjusting bolt 313 with the support plate 32, the pushing stroke can be precisely controlled, making the focusing coil coaxial with the reference hole 2a, thus ensuring the reliability of the focusing coil.

[0037] In one embodiment, please refer to Figure 1 and Figure 2 The support plate 32 has multiple folded edges A. Two folded edges A are provided on opposite sides of the reference hole 32a in the left-right direction, and two folded edges A are provided on opposite sides of the reference hole 32a in the front-back direction. The third adjusting bolt 313 is threadedly engaged with the folded edges A. For example, the support plate 32 has upwardly folded edges A on both the front-back and left-back directions. This not only improves the structural strength of the support plate 32, but also provides stable support for the adjustment of the third adjusting bolt 313.

[0038] In one embodiment, please refer to Figure 1 and Figure 2The support plate 32 has subtractive grooves extending through its upper and lower sides. For example, the support plate 32 has subtractive grooves in both the front-back and left-right directions, so that the projected shape of the support plate 32 in the up-down direction is approximately rhomboid. In this way, on the one hand, the manufacturing cost of the adjustment device 100 can be reduced without affecting the support function; on the other hand, the pitch adjustment stroke of the third adjustment bolt 313 can be reduced to improve the adjustment accuracy of the focusing coil.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. All modifications, equivalent substitutions, improvements, etc., within the spirit and principles of this application are included within the scope of protection of this application.
