Technical Field

[0001] The present application relates to but is not limited to the technical field of electron accelerator equipment, and in particular to an electron accelerator support device and an electron accelerator equipment. Background Art

[0002] As the global demand for sterilization of medical devices, drugs and food increases, the demand for electron irradiation processing services is also increasing, which has led to a rapid growth in the demand for electron accelerator equipment.

[0003] The electron beam generated by the electron accelerator needs to be absorbed by a shield, and sufficient space is required for installing the accelerator and replacing parts in the electron accelerator, which makes the shield of a high-power electron irradiation accelerator generally large in volume, and the construction of a large shield consumes a lot of financial and material resources. Therefore, a support device for an electron accelerator is needed, which can reduce the volume of the operating space occupied when installing the electron accelerator, thereby reducing the volume of the shield and saving costs. Summary of the invention

[0004] The present application provides an electron accelerator support device and an electron accelerator device, which can simplify the steps of installing the electron accelerator device and reduce the volume of the operating space required during the installation of the electron accelerator device, which is conducive to reducing the volume of a shielding body that accommodates and protects the electron accelerator device.

[0005] On the one hand, the present application provides an electron accelerator support device, which includes: a bracket, a connecting structure and an adjusting structure. The connecting structure matches with multiple coils of the electron accelerator device and is used to connect the coils to form a coil assembly; the adjusting structure is arranged on the bracket and matches with the connecting structure. When the coil assembly is placed in the bracket, the coil assembly is connected to the adjusting structure through the connecting structure, and the connecting structure can move relative to the adjusting structure; by adjusting the posture of the adjusting structure relative to the bracket, the adjusting structure can drive the coil assembly to move relative to the bracket.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0031] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0032] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0033] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0034] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0035] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] In recent years, electron irradiation sterilization technology has developed rapidly. Electron irradiation sterilization has strong penetration, simple operation, and no residual toxicity, making it widely used in the fields of medical equipment, medicine and food sterilization. Electron accelerator equipment can generate high-speed electron beams, which need to be absorbed by shielding of sufficient thickness to reduce the damage caused by the electron beam to personnel.

[0037] In the process of installing the accelerator in the electron accelerator equipment and replacing the parts in the electron accelerator equipment, a sufficiently large space is required. For example, the shielding hall space of the accelerator body is mainly used to install the accelerator device, replace the accelerating tube and vacuum components, and to accommodate the hoisting equipment used when installing and replacing the parts of the accelerator. Since the accelerating tube is located in the inner center of the coil assembly of the accelerator, the accelerating tube must be vertically hoisted into the coil assembly, and the coil assembly is located at the top of the accelerator device. Therefore, a hoisting operation space with a height at least the same as the length of the accelerating tube needs to be reserved in the space above the accelerator device. However, in the normal operation of the accelerator, the reserved hoisting operation space no longer plays a role. At present, in order to ensure sufficient installation space, the height of the shielding body is generally two to three times the overall height of the accelerator device, which causes a great waste of the volume of the shielding body.

[0038] In the related art, during the installation of the accelerator device of the electron accelerator equipment, it is necessary to make each coil in the accelerator device parallel to the ground and coaxial, so as to facilitate the hoisting of the accelerating tube. And after completing the preliminary installation of the coil, each coil needs to be leveled, which further increases the operation steps of installing the electron accelerator equipment. Therefore, it is necessary to change the installation method of the electron accelerator equipment and the supporting device of the electron accelerator equipment to simplify the steps of installing the electron accelerator equipment and reduce the volume of the operating space required during the installation of the electron accelerator equipment, thereby reducing the volume of the shielding body that accommodates and protects the electron accelerator equipment.

[0039] On this basis, the present application embodiment provides an electron accelerator system, referring to Figure 1 and Figure 2 , Figure 1 Schematic diagram of the structure of the electron acceleration system provided in the embodiment of the present application Figure 1 , Figure 2 Schematic diagram of the structure of the electron acceleration system provided in the embodiment of the present application Figure 2 The electron accelerator system comprises: an electron accelerator device 5 and a shielding body 6 . The shielding body 6 has a shielding cavity 611 matching the electron accelerator device, and the bracket 1 is fixed in the shielding cavity 611 to fix the electron accelerator device 5 in the shielding cavity 611 .

[0040] In the embodiment of the present application, the electron accelerator device 5 is used to generate a high-speed electron beam. A shielding body 6 may be provided for the electron accelerator device 5 to absorb the escaped electrons through the shielding body 6 .

[0041] Exemplarily, the shielding body 6 may be configured to include a main machine hall 61 and a beam maze 62, and the main machine hall 61 and the beam maze 62 may be made of concrete. The internal structure of the main machine hall 61 and the beam maze 62 may be configured according to the structure of the electron accelerator device 5. For example, a shielding cavity 611 matching the accelerator device of the electron accelerator device 5 may be configured in the main machine hall 61, and the space of the shielding cavity 611 is larger than the volume of the accelerator device. A mounting hole 612 may be configured at the bottom of the main machine hall 61, so that the main machine hall 61 and the beam maze 62 are connected through the mounting hole 612, so that a part of the accelerator device located in the main machine hall 61 extends through the mounting hole 612 to the beam maze 62.

[0042] In another example, when the height of the accelerator device in the main machine hall 61 is 2.8 meters, the height of the shielding chamber 611 in the main machine hall 61 can be set to 5 meters. In this way, not only the installation of the accelerator device can be completed, but also the height of the main machine hall 61 can be reduced, thereby reducing the volume of the shielding body 6.

[0043] In addition, the present application embodiment also provides an electron accelerator device 5, referring to Figure 3 , Figure 3 Schematic diagram of the structure of the electron accelerator device provided in the embodiment of the present application. The electron accelerator device 5 includes: an accelerator device and an electron accelerator support device. The accelerator device includes at least two coils; at least two coils are fixedly connected by a connecting structure 2, and the accelerator device is installed on the bracket 1 through the connecting structure 2 and the adjustment mechanism.

[0044] In the embodiment of the present application, the coil in the accelerator device is used to generate a changing magnetic field, and multiple coils can be provided in the accelerator device. Correspondingly, a connection structure 2 matching the multiple coils can be provided in the electron accelerator support device, so that the multiple coils are fixedly connected through the connection structure 2 to form a coil assembly.

[0045] Exemplarily, an adjustment mechanism matching the connection structure 2 can be provided in the electron accelerator support device, and the coil assembly can be moved in the adjustment structure 3. The coil assembly can also be fixed in the electron accelerator support device through the adjustment structure 3 to complete the installation of the accelerator device.

[0046] At the same time, the present application embodiment also provides an electron accelerator support device, referring to Figure 4 and Figure 5 , Figure 4 A schematic diagram of the structure of an electron accelerator support device provided in an embodiment of the present application, Figure 5 A schematic diagram of the structure of the coil assembly of the electron accelerator device provided in the embodiment of the present application. The electron accelerator support device includes: a bracket 1, a connecting structure 2 and an adjusting structure 3. Among them, the connecting structure 2 matches the multiple coils of the electron accelerator device 5, and is used to connect the various coils to form a coil assembly; the adjusting structure 3, the adjusting structure 3 is arranged on the bracket 1, and matches the connecting structure 2. When the coil assembly is placed in the bracket 1, the coil assembly is connected to the adjusting structure 3 through the connecting structure 2, and the connecting structure 2 can move relative to the adjusting structure 3; by adjusting the posture of the adjusting structure 3 relative to the bracket 1, the adjusting structure 3 can drive the coil assembly to move relative to the bracket 1.

[0047] In the present application embodiment, Figure 3 and Figure 4 As shown, a bracket 1 can be provided in the electron accelerator support device to provide installation points and support for the electron accelerator support device and the accelerator device through the bracket 1 , and the accelerator device can be fixedly installed in the shielding body 6 through the bracket 1 .

[0048] Exemplarily, a frame can be provided in the bracket 1. For example, a lower frame 11 and an upper frame 12 can be provided, and both the lower frame 11 and the upper frame 12 can be structures including four columns, so that a space for accommodating an accelerator device can be formed in each frame. The lower frame 11 and the upper frame 12 can be fixedly connected along the long axis direction of the frame by bolts.

[0049] In the embodiment of the present application, the coil in the accelerator device of the electron accelerator equipment 5 is used to generate a changing magnetic field, and multiple coils can be provided in the accelerator device. In order to achieve the connection and fixation of the multiple coils, a connection structure 2 matching the multiple coils can be provided in the electron accelerator support device, so that the multiple coils are fixedly connected in sequence through the connection structure 2 to form a coil assembly.

[0050] For example, Figure 5 As shown, when the accelerator device includes three coils, the connection structure 2 can be set to include two sets of connection components, so that the three coils can be fixedly connected in sequence through the two sets of connection components. And the three coils can be placed in a coaxial state by setting the connection components.

[0051] In the present application embodiment, Figure 4 As shown, the adjustment structure 3 can be provided on the bracket 1, and at least a part of the adjustment structure 3 can be provided as a structure that can move relative to the bracket 1, so that the posture of the adjustment structure 3 relative to the bracket 1 can be adjusted. The adjustment structure 3 can be provided to match the connection structure 2. For example, a part of the connection structure 2 can be provided inside the adjustment structure 3, and another part of the connection structure 2 can be provided to abut against the adjustment structure 3.

[0052] For example, refer to Figure 6 , Figure 6 Schematic diagram of the assembly process of the coil assembly of the electron accelerator device provided in the embodiment of the present application Figure 1 . During the assembly of the accelerator device, the lower frame 11 can be leveled and fixed in the shielding body 6. The third coil 53 can be placed at the bottom of the lower frame 11 first, and then the second coil 52 can be fixedly connected to the upper end of the third coil 53 through the connecting structure 2, and then the first coil 51 can be fixedly connected to the upper end of the second coil 52 through the connecting structure 2 to complete the assembly of the three coils. Then the accelerating tube 54 in the accelerator device can be hoisted into the coil assembly from the top of the lower frame 11, and then the upper frame 12 and the lower frame 11 can be fixed and leveled. During the hoisting process, since the coil assembly is located inside the bracket 1 and at the bottom of the bracket 1, the hoisting height of the accelerating tube 54 can be reduced, thereby reducing the reserved height of the shielding cavity 611 in the shielding body 6.

[0053] For another example, see Figure 7 , Figure 7Schematic diagram of the assembly process of the coil assembly of the electron accelerator device 5 provided in the embodiment of the present application Figure 2 After the accelerating tube 54 is hoisted in the coil assembly, the accelerating tube 54 can be fixed to the coil assembly, and the coil assembly can be lifted to a position corresponding to the adjustment structure 3 in the upper frame 12, that is, a part of the connecting structure 2 is placed in the adjustment structure 3, and then the posture of the adjustment structure 3 is adjusted to complete the adjustment of the installation position of the accelerator device on the bracket 1 through the adjustment structure 3.

[0054] The electron accelerator support device provided in the embodiment of the present application is provided with a bracket 1, and the bracket 1 can provide installation points and support for other parts and accelerator devices in the electron accelerator support device. In addition, a connection structure 2 matching the coil in the accelerator device of the electron accelerator equipment 5 is provided, and multiple coils can be fixedly connected in sequence through the connection structure 2. At the same time, an adjustment structure 3 matching the connection structure 2 is provided on the bracket 1, and the connection structure 2 can move relative to the adjustment structure 3. In the process of assembling the accelerator device, multiple coils can be fixedly connected from the bottom of the bracket 1 in sequence upward through the connection structure 2 to form a coil assembly, and then the acceleration tube 54 in the accelerator device is hoisted into the coil assembly and fixed with the coil assembly, and then the coil assembly is lifted from the bracket 1 to correspond to the adjustment structure 3, so as to connect the connection structure 2 with the adjustment structure 3, and finally the adjustment structure 3 can be adjusted to drive the coil assembly to move relative to the bracket 1, so that the coil assembly can be adjusted to a suitable position.

[0055] Compared with the related art, each coil is fixedly connected to the bracket 1 separately, and then the accelerating tube 54 is hoisted into the coil. The electron accelerator support device provided in the embodiment of the present application can connect multiple coils through the connecting structure 2 to form an integral coil assembly, and then hoist the accelerating tube 54, and then lift the coil assembly and the accelerating tube 54 relative to the bracket 1 to the installation position. In this process, there is no need to adjust the assembly position of a single coil, but the assembly position of the entire coil assembly is adjusted by the adjustment structure 3, and there is no need to hoist the accelerating tube 54 into a coil assembly with a higher height that is already in the installation position (the hoisting height of the accelerating tube 54 is reduced). Therefore, the electron accelerator support device provided in the embodiment of the present application can simplify the steps of installing the electron accelerator device 5, and reduce the volume of the operating space required in the process of installing the electron accelerator device 5, so as to reduce the volume of the shielding body 6 that accommodates and protects the electron accelerator device 5.

[0056] In some possible embodiments of the present application, refer to Figure 8 , Figure 8A schematic diagram of the structure of the first connecting assembly in the electron accelerator support device provided in an embodiment of the present application. The coil includes a second coil 52 and a third coil 53, and the connecting structure 2 includes a connecting cylinder 211 and a connecting rod 212; along the axial direction Z of the coil assembly, the connecting cylinder 211 is located between the second coil 52 and the third coil 53, and the connecting rod 212 is connected to the second coil 52 and the third coil 53 respectively, so as to press and fix the second coil 52 and the third coil 53 at both ends of the connecting cylinder 211, and make the second coil 52 and the third coil 53 coaxial.

[0057] In the present application embodiment, Figure 6 and Figure 7 As shown, the accelerator device includes a second coil 52 and a third coil 53, and the second coil 52 and the third coil 53 need to be fixedly connected along the axial direction Z. Then, a first connecting component 21 can be provided for the second coil 52 and the third coil 53, so as to fix the second coil 52 and the third coil 53 through the first connecting component 21.

[0058] For example, Figure 8 As shown, a connecting cylinder 211 and a plurality of connecting rods 212 may be provided in the first connecting component 21. For example, the connecting cylinder 211 may be provided in a cylindrical shape having a diameter close to or consistent with the diameter of the second coil 52, and abutment rings 2113 matching the second coil 52 and the third coil 53 may be provided at both ends of the connecting cylinder 211, respectively. Through holes may be provided on the abutment rings 2113, for example, six corresponding through holes are provided on the two abutment rings 2113 along the circumferential direction C of the abutment rings 2113, respectively, and the through holes match the connecting rods 212. Correspondingly, the second coil 52 and the third coil 53 have through holes corresponding to the through holes of the abutment rings 2113. The connecting rod 212 may be a threaded rod or a bolt. As shown Figure 5 and Figure 6 As shown, the third coil 53 can be placed on the third supporting member 15 in the bracket 1, and the third supporting member 15 is located at the bottom of the bracket 1. Then, the connecting tube 211 is placed above the third coil 53, and then the second coil 52 is placed above the connecting tube 211. The connecting rod 212 is passed through the second coil 52, the abutment ring 2113 and the third coil 53 in sequence. Finally, a nut matching the thread on the connecting rod 212 is used to screw the nut in, so as to complete the fixed connection of the second coil 52 and the third coil 53 using the first connecting assembly 21.

[0059] In another example, the positions of the through holes on the abutment ring 2113, the through holes for connection on the second coil 52, and the through holes for connection on the third coil 53 can be arranged so that the second coil 52 and the third coil 53 are coaxial. For example, along the circumferential direction C of the coil assembly, the multiple through holes on the abutment ring 2113 can be evenly distributed on the abutment ring 2113, and the multiple through holes on the second coil 52 and the third coil 53 can also be evenly distributed. In this way, after the second coil 52 and the third coil 53 are fixedly connected by the first connecting assembly 21, the coaxiality of the second coil 52 and the third coil 53 can meet the requirements of assembly accuracy.

[0060] In the above embodiment, since the connecting cylinder 211 is provided between the second coil 52 and the third coil 53, the second coil 52 and the third coil 53 can be connected through the connecting cylinder 211, and the connecting rod 212 is passed through the second coil 52 and the third coil 53, and the second coil 52, the connecting cylinder 211 and the third coil 53 can be fixed in sequence through the connecting rod 212, thereby completing the fixed connection of the second coil 52 and the third coil 53. By setting the processing accuracy of the connecting cylinder 211, the second coil 52 and the third coil 53 after the fixed connection through the connecting cylinder 211 and the connecting rod 212 can be in a coaxial position, thereby reducing the steps of adjusting the coaxiality of the second coil 52 and the third coil 53 when assembling.

[0061] In some possible embodiments of the present application, Figure 5 and Figure 8 As shown, an observation notch 2111 is provided on the circumferential C-side wall 2112 of the connecting tube 211 .

[0062] In the present application embodiment, Figure 6 As shown, in the process of hoisting the accelerating tube 54 into the coil assembly, it is necessary to control the gap between the accelerating tube 54 and the coil so that there is no collision or friction between the accelerating tube 54 and the coil. Therefore, an observation notch 2111 for observation can be provided on the connecting tube 211, so that the posture of the accelerating tube 54 after entering the coil assembly can be observed from the observation notch 2111.

[0063] Exemplarily, a through hole may be provided on the circumferential C side wall 2112 of the connecting cylinder 211, and the through hole may be used as the observation notch 2111. For example, two observation notches 2111 may be provided on the circumferential C side wall 2112 of the connecting cylinder 211, and the two observation notches 2111 are located at opposite positions in the radial direction X of the coil assembly. Three or four observation notches 2111 may also be provided on the circumferential C side wall 2112 of the connecting cylinder 211. The observation notch 2111 may be provided in a rectangular through hole, a circular through hole, an elliptical through hole, or the like.

[0064] In the above embodiment, since an observation notch 2111 is provided on the circumferential C-side wall 2112 of the connecting tube 211, during the process of hoisting the accelerating tube 54 into the coil assembly, the movement state of the accelerating tube 54 in the coil assembly and the gap between the accelerating tube 54 and the inner wall of the coil assembly can be observed through the observation notch 2111, thereby facilitating the control of the movement path of the accelerating tube 54 through the observation notch 2111, thereby reducing the risk of the accelerating tube 54 colliding with the inner wall of the coil assembly during the descent process, and also facilitating the speed of hoisting the accelerating tube 54 into the coil assembly.

[0065] In some possible embodiments of the present application, Figure 4 and Figure 5 As shown, the coil also includes a first coil 51, and the connecting structure 2 also includes a connecting ring 221 and a fastener 222. The connecting ring 221 matches both the first coil 51 and the second coil 52, and the connecting ring 221 is located between the first coil 51 and the second coil 52; along the axial direction Z of the coil assembly, the fastener 222 fixes the connecting ring 221 and the second coil 52 at one end away from the third coil 53, and makes the first coil 51 coaxial with the second coil 52.

[0066] In the embodiment of the present application, the accelerator device further includes a first coil 51, and the first coil 51 and the second coil 52 need to be fixedly connected along the axial direction Z. A second connecting component 22 may be provided for the first coil 51 and the second coil 52, so as to fix the first coil 51 and the second coil 52 through the second connecting component 22.

[0067] For example, Figure 4 As shown, a connecting ring 221 and a fastener 222 may be provided in the first connecting component 21. For example, corresponding through holes may be provided on the first coil 51 and the second coil 52, respectively. The through holes penetrate the bobbins of the first coil 51 and the second coil 52 along the axial direction Z of the coil assembly. The bobbins are hollow structures, and the winding wire may be wound on the bobbins to support the winding wire through the bobbins. For example, six corresponding through holes may be provided on the first coil 51 and the second coil 52, respectively. Figure 5 As shown, the connecting ring 221 can be set to a cylindrical shape, and the outer diameter of the connecting ring 221 is larger than the diameter of the through hole on the first coil 51 and the second coil 52. The six connecting rings 221 can be respectively abutted against the edges of the corresponding through holes on the first coil 51 and the second coil 52 to limit the axial Z movement between the first coil 51 and the second coil 52. The fastener 222 can be a bolt pair that matches the through holes on the first coil 51 and the second coil 52, so that the first coil 51 and the second coil 52 are pressed against the two ends of the connecting ring 221 by the bolt pair.

[0068] In another example, a plurality of connecting rings 221 may be evenly arranged between the first coil 51 and the second coil 52 along the circumferential direction C of the coil assembly, that is, the corresponding through holes on the first coil 51 and the second coil 52 are evenly distributed on the first coil 51 and the second coil 52 along the circumferential direction C of the coil assembly. In this way, after the first coil 51 and the second coil 52 are fixedly connected by a bolt pair, the coaxiality of the first coil 51 and the second coil 52 can meet the requirements of assembly accuracy.

[0069] In the above embodiment, since the connecting ring 221 is provided between the first coil 51 and the second coil 52, the second coil 52 and the third coil 53 can be connected through the connecting ring 221, and the fastener 222 is passed through the through holes on the first coil 51 and the second coil 52, and the first coil 51, the connecting ring 221 and the second coil 52 can be fixed in sequence through the fastener 222. By setting the processing accuracy of the connecting cylinder 211 and the position accuracy of the corresponding through holes on the first coil 51 and the second coil 52 for passing the fastener 222, the first coil 51 and the second coil 52 can be in a coaxial position after being fixedly connected by the connecting ring 221 and the fastener 222, thereby reducing the steps for adjusting the coaxiality of the first coil 51 and the second coil 52 when assembling.

[0070] In some possible embodiments of the present application, refer to Fig. 9 , Fig. 9 This is a schematic diagram of the structure of the first adjustment component of the electron accelerator support device provided in the embodiment of the present application. Figure 4 and Figure 7 As shown, the adjustment structure 3 includes a first support member 311 and a first adjustment member 312. The first support member 311 is movably arranged in the bracket 1 along the axial direction Z through the first adjustment member 312, and the first support member 311 has a first avoidance gap. When the coil assembly is placed in the bracket 1 and the connecting rod 212 is located in the first avoidance gap, the connecting rod 212 can move relative to the bracket 1 along the axial direction Z until the connecting tube 211 is connected to the first support member 311, so as to limit the movement of the connecting tube 211 relative to the bracket 1 along the axial direction Z.

[0071] In the present application embodiment, Figure 6 As shown in FIG. 1 , after the coil assembly is assembled and the accelerating tube 54 is hoisted into the coil assembly. Figure 7 As shown, the coil assembly can be lifted upward together with the accelerating tube 54, so that the coil assembly and the accelerating tube 54 are moved from the lower frame 11 to the upper frame 12. In order to fix the coil assembly in the upper frame 12, a first adjustment assembly 31 can be provided in the upper frame 12 to fix and adjust the position of the first connecting assembly 21 in the bracket 1 through the first adjustment assembly 31.

[0072] For example, Fig. 9 As shown, the first adjustment component 31 can be set to a structure including a first support member 311 and a first adjustment member 312. The structure of the first support member 311 can be set according to the structure of the upper frame 12. For example, the first support member 311 can be set to a plate-like shape that is approximately rectangular, and a first avoidance gap can be set on the first support member 311, so that the coil assembly can pass through the first support member 311 through the first avoidance gap. A plurality of lugs 314 can be set on the first support member 311, such as setting a lug 314 at a position corresponding to each corner of the rectangular first support member 311 in the upper frame 12, and the lug 314 can be fixed to the column of the upper frame 12 by bolts. The first adjustment member 312 can be set between the lug 314 and the first support member 311. For example, the first adjustment member 312 can adopt a stud and a nut. A threaded hole matching the stud can be set on the lug 314, and a through hole matching the stud can be set on each corner of the first support member 311. The stud can be threadedly connected to the lug 314 along the axial direction Z of the coil assembly. The first support member 311 is passed through four bolts, and at least two nuts are arranged on the same bolt, and the at least two nuts are respectively located above and below the first support member 311.

[0073] In this way, Figure 7 As shown, the first support member 311 can be movably arranged in the bracket 1 through four first adjusting members 312. For example, after the coil assembly is lifted into the upper frame 12 and the connecting rod 212 is located at the position of the first support member 311, the first support member 311 can be installed in the bracket 1 through the first adjusting member 312. At this time, the connecting cylinder 211 is inserted into the first avoidance gap of the first support member 311, and the coil assembly can be moved downward in the vertical direction until the abutment ring 2113 on the connecting cylinder 211 that abuts against the second coil 52 abuts against the edge of the first support member 311. The connecting cylinder 211 can be supported and limited by the first support member 311, that is, the coil assembly is supported along the axial direction Z of the coil assembly. Then, the position of the first support member 311 relative to the bracket 1 can be adjusted by adjusting the four first adjusting members 312, so that the position of the coil assembly relative to the bracket 1 can be adjusted.

[0074] In the above embodiment, since the first support member 311 has the first avoidance notch, the coil assembly can be inserted into the first support member 311, and the connecting tube 211 can be connected to the first support member 311 to support the coil assembly. In addition, the first support member 311 is movably arranged in the bracket 1 through the first adjustment member 312, and the position of the first support member 311 relative to the bracket 1 can be adjusted through the first adjustment member 312, and the coil assembly can be driven to move relative to the bracket 1 through the first support member 311, so that the position of the coil assembly relative to the bracket 1 can be adjusted, and the coil assembly can be conveniently adjusted to the desired installation position.

[0075] In some possible embodiments of the present application, Fig. 9 As shown, the adjustment structure 3 also includes a first limit member 313, and the first limit member 313 includes at least two first limit support plates 3131. The at least two first limit support plates 3131 are arranged on the edge of the avoidance gap on the first support member 311 along the circumferential direction C of the coil assembly to enclose and form a first limit gap matching the connecting tube 211. A part of the connecting tube 211 can move relative to the bracket 1 along the axial direction Z in the first limit gap until another part of the connecting tube 211 abuts against the first limit support plate 3131.

[0076] In the embodiment of the present application, after the connecting tube 211 is passed through the first avoidance gap of the first support member 311, in order to facilitate the connection between the connecting tube 211 and the first support member 311, a first limit member 313 can be provided on the first support member 311 to limit the movement of the connecting tube 211 relative to the first support member 311 through the first limit member 313.

[0077] Exemplarily, the first stopper 313 can be set to a structure similar to a C-shaped card. For example, the inner diameter of the first stopper 313 can be set according to the outer diameter of the circumferential C-side wall 2112 of the connecting cylinder 211 and the outer diameter of the abutting ring 2113 of the connecting cylinder 211, and the inner diameter of the first stopper 313 can be larger than the outer diameter of the circumferential C-side wall 2112 of the connecting cylinder 211 and smaller than the outer diameter of the abutting ring 2113, and an avoidance groove corresponding to the connecting rod 212 can be set on the first stopper 313. At the same time, the outer diameter of the first stopper 313 can be larger than the inner diameter of the first avoidance notch on the first support member 311. The first limiting member 313 can be clamped on the circumferential C side wall 2112 of the connecting tube 211 along the radial direction X of the coil assembly, so that the lower surface of the first limiting member 313 abuts against the edge of the first avoidance gap of the first support member 311, and the abutment ring 2113 of the connecting tube 211 abuts against the upper surface of the first limiting member 313, so that the connecting tube 211 is located in the first avoidance gap of the first limiting member 313.

[0078] As another example, the first limiting member 313 can be set to a structure of multiple first limiting support plates 3131. For example, the first limiting support plates 3131 can be set to a structure that is approximately fan-shaped. For example, if the first limiting member 313 is set to two symmetrical fan-shaped structures, the two fan-shaped first limiting members 313 can be clamped between the first support member 311 and the abutment ring 2113 of the connecting tube 211 along the radial direction X of the coil assembly.

[0079] In the above embodiment, since the first limiting member 313 is provided between the first supporting member 311 and the connecting tube 211, the movement of the connecting tube 211 relative to the first supporting member 311 can be limited by the first limiting member 313. In addition, the first limiting member 313 is provided to include a structure including at least two first limiting supporting plates 3131, so that the plurality of first limiting supporting plates 3131 can be inserted between the first supporting member 311 and the connecting tube 211 along the radial direction X of the coil assembly, which is conducive to quickly completing the positioning and support of the coil assembly in the bracket 1.

[0080] In some possible embodiments of the present application, refer to Fig.10 , Fig.10 A schematic diagram of the structure of the second adjustment component in the electron accelerator support device provided in an embodiment of the present application. The bracket 1 includes a first bearing member 13, and the first bearing member 13 has a second avoidance gap matching the accelerating tube 54 of the electron accelerator device 5; the adjustment structure 3 includes a second adjustment member 321, and the second adjustment member 321 is movably arranged on the first bearing member 13 along the radial direction X of the coil assembly; when the coil assembly is placed in the bracket 1 and the accelerating tube 54 is located in the second avoidance gap, the third coil 53 is connected to the first bearing member 13 along the axial direction Z, and the second adjustment member 321 abuts against the third coil 53 along the radial direction X of the coil assembly.

[0081] In the present application embodiment, Figure 4 and Figure 7 As shown, a first bearing member 13 may be provided in the bracket 1 to provide support for the third coil 53 through the first bearing member 13. For example, the first bearing member 13 may be provided at the connection between the upper frame 12 and the lower frame 11, the first bearing member 13 may be provided as a plate-like structure, and a second avoidance gap may be provided on the first bearing member 13, so that the coil assembly or the accelerating tube 54 may pass through the first bearing member 13 through the second avoidance gap.

[0082] For example, Figure 7 and Fig.10As shown, a second adjustment component 32 can be provided on the first carrier 13 to adjust the position of the third coil 53 in the coil assembly relative to the bracket 1 along the radial direction X through the second adjustment component 32. For example, the second adjustment component 32 can be provided as a structure of a second fixing block 323 and a second adjustment component 321. Along the circumferential direction C of the coil assembly, three second fixing blocks 323 can be evenly provided at the edge of the second avoidance notch on the first carrier 13. The second adjustment component 321 can be a bolt, and threaded holes matching the bolts can be provided on the three second fixing blocks 323, respectively. In this way, as Figure 7 As shown, when the coil assembly is lowered to the point where the third coil 53 is connected to the first carrier 13, the positions of the three second adjustment members 321 relative to the first carrier 13 can be adjusted to drive the third coil 53 to move relative to the bracket 1 along the radial direction X of the coil assembly.

[0083] In the above embodiment, since the first bearing member 13 is provided in the bracket 1, the coil at the lowest end of the coil assembly can be supported by the first bearing member 13. In addition, a second adjusting member 321 is provided on the first bearing member 13, and the coil connected to the first bearing member 13 can be driven by the second adjusting member 321 to move relative to the bracket 1 along the radial direction X of the coil assembly, so as to facilitate adjustment of the angle between the axis of the coil assembly and the vertical direction, so that the axis of the coil assembly can be quickly adjusted to a desired position.

[0084] In some possible embodiments of the present application, Figure 7 and Fig.10 As shown, the adjustment structure 3 also includes a second limiting member 322, and the second limiting member 322 includes at least two second limiting support plates 3221. The at least two second limiting support plates 3221 are arranged on the edge of the second avoidance gap on the first carrier 13 along the circumferential direction C of the coil assembly to enclose and form a second limiting gap matching the accelerating tube 54, and one end of the third coil 53 away from the second coil 52 abuts against the second limiting support plate 3221.

[0085] In the embodiment of the present application, in order to facilitate supporting the third coil 53 on the first carrier 13 , a second limiter 322 may be provided on the first carrier 13 to limit the movement of the third coil 53 relative to the first carrier 13 through the second limiter 322 .

[0086] Exemplarily, the second stopper 322 can be set to a nearly annular structure. For example, the inner diameter of the second stopper 322 can be set according to the outer diameter of the third coil 53 and the diameter of the accelerating tube 54, so that the inner diameter of the second stopper 322 can be larger than the diameter of the accelerating tube 54 and smaller than the outer diameter of the third coil 53. At the same time, the outer diameter of the second stopper 322 can be larger than the inner diameter of the second avoidance gap on the first bearing member 13. Then the second stopper 322 can be clamped between the third coil 53 and the first bearing member 13 along the axial direction Z of the coil assembly, so that the lower surface of the second stopper 322 abuts against the edge of the second avoidance gap of the first stopper 313, and the lower surface of the third coil 53 abuts against the upper surface of the second stopper 322.

[0087] In another example, the second limiting member 322 can be set to a structure of multiple second limiting support plates 3221. For example, the second limiting support plate 3221 can be set to an approximately semi-annular structure. For example, the second limiting member 322 can be set to two symmetrical semi-annular structures. The two semi-annular second limiting members 322 can be clamped between the first carrier 13 and the third coil 53 along the radial direction X of the coil assembly.

[0088] In the above embodiment, since the second limiting member 322 is provided between the first bearing member 13 and the coil assembly, the movement of the coil assembly relative to the first bearing member 13 can be limited by the second limiting member 322. And the second limiting member 322 is provided to include a structure of at least two second limiting support plates 3221, so that the plurality of second limiting support plates 3221 can be inserted between the first bearing member 13 and the coil assembly along the radial direction X of the coil assembly, which is conducive to quickly completing the support of the coil assembly on the first bearing member 13.

[0089] In some possible embodiments of the present application, Figure 3 and Figure 4 As shown, the bracket 1 includes a second bearing member 14 . The second bearing member 14 is located in the bracket 1 at a position corresponding to the accelerating tube 54 of the electron accelerator device 5 . The second bearing member 14 is used to bear and fix the accelerating tube 54 .

[0090] In the embodiment of the present application, after the installation of the coil assembly in the upper frame 12 is completed, the accelerating tube 54 can be supported and fixed. Then, a second bearing member 14 corresponding to the lower end of the accelerating tube 54 can be provided in the bracket 1, the second bearing member 14 can be provided as a plate-like structure, a fixing hole matching the flange 16 of the accelerating tube 54 can be provided on the second bearing member 14, the flange 16 can be connected to the accelerating tube 54, and then the flange 16 can be fixed to the second bearing member 14. A through hole can also be provided on the second bearing member 14, the through hole corresponding to the accelerating tube 54, so that the accelerating tube 54 can pass through the through hole to connect with the vacuum assembly 55.

[0091] In the above embodiment, since the second supporting member 14 corresponding to the accelerating tube 54 is provided in the bracket 1, the accelerating tube 54 can be supported and fixed by the second supporting member 14, thereby reducing the risk of the accelerating tube 54 shaking relative to the bracket 1, and facilitating the assembly of the vacuum assembly 55 connected to the lower end of the accelerating tube 54.

[0092] In some possible embodiments of the present application, Figure 3 and Figure 4 As shown, the bracket 1 includes a third carrier 15, and the third carrier 15 is located in the bracket 1 at a position corresponding to the scanning magnet 56 of the electron accelerator device 5; the adjustment structure 3 includes a third adjustment component 33, and at least a part of the third adjustment component 33 is movably arranged on the third carrier 15 along the radial direction X of the coil component; when the scanning magnet 56 is arranged on the third carrier 15 and abuts against the third adjustment component 33, by adjusting the position of the third adjustment component 33 along the radial direction X of the coil component relative to the bracket 1, the scanning magnet 56 can be driven to move along the radial direction X relative to the bracket 1.

[0093] In the embodiment of the present application, a third bearing member 15 may be provided at the lower end of the lower frame 11, and the third bearing member 15 may be provided as a plate-like structure. Figure 3 As shown, the scanning magnet 56 in the electron accelerator device 5 can be arranged on the third carrier 15, so that the scanning magnet 56 is connected to the accelerating tube 54 through the vacuum component 55. In addition, a third adjusting component 33 matching the scanning magnet 56 can be arranged on the third carrier 15, so that the position of the scanning magnet 56 relative to the bracket 1 can be adjusted and limited by the third adjusting component 33.

[0094] For example, Figure 4 As shown, the third adjustment assembly 33 can be configured to include a third fixing block 331 and a third adjustment member 332. A plurality of third fixing blocks 331 can be provided on the third carrier 15 along the circumferential direction C of the scanning magnet 56. The third adjustment member 332 can be a bolt, and a threaded hole matching the bolt can be provided on each third fixing block 331. Figure 3 As shown, when the scanning magnet 56 is placed on the third carrier 15, the position of the third adjusting member 332 around the scanning magnet 56 relative to the third carrier 15 can be adjusted to drive the scanning magnet 56 to move relative to the bracket 1 along the radial direction X of the coil assembly, so that the scanning magnet 56 can be placed in a desired position.

[0095] In the above embodiment, since the third bearing member 15 is provided in the bracket 1, the scanning magnet 56 can be installed and supported by the third bearing member 15. In addition, a third adjustment component 33 is provided on the third bearing member 15, and the scanning magnet 56 can be driven by the third adjustment component 33 to move relative to the bracket 1 along the radial direction X of the coil assembly, so as to facilitate the adjustment of the position of the scanning magnet 56 in the radial direction X of the coil assembly, so that the scanning magnet 56 can be quickly adjusted to a desired position.

[0096] In some possible embodiments of the present application, Figure 3 and Figure 4 As shown, the electron accelerator support device further includes a beam support assembly 4 , which is disposed on the third carrier 15 , and is used to carry and fix the scanning box 57 of the electron accelerator device 5 .

[0097] In the embodiment of the present application, a beam support assembly 4 can be provided below the lower frame 11, so as to install the scanning box 57 of the electron accelerator device 5 below the scanning magnet 56 through the beam support assembly 4. For example, the beam support assembly 4 can be provided as a structure including a suspension rod 41 and a support plate 42, and the length of the suspension rod 41 and the size of the support plate 42 can be set according to the size and shape of the scanning box 57. The suspension rod 41 can be connected below the third bearing member 15 in a hanging manner, and the support plate 42 can be connected to the end of the suspension rod 41 away from the third bearing member 15. In this way, the scanning box 57 can be fixed below the scanning magnet 56 through the support plate 42 and the suspension rod 41, so as to facilitate the installation of the scanning box 57.
