Description

Technical Field

[0001] This application relates to, but is not limited to, the field of electron accelerator equipment technology, and in particular to an electron accelerator support device and an electron accelerator device. Background Technology

[0002] With the increasing global demand for sterilization of medical devices, pharmaceuticals, and food, the demand for electron irradiation processing services is also growing, leading to a rapid increase in demand for electron accelerator equipment.

[0003] Electron beams generated by electron accelerators require shielding for absorption, and the installation and replacement of components within these devices necessitate sufficient space. This results in the generally large size of shields for high-power electron irradiation accelerators, and constructing such large shields requires substantial financial and material resources. Therefore, a support device for electron accelerators is needed that can reduce the operating space required for installation, thereby reducing the size of the shield and saving costs. Summary of the Invention

[0004] This application provides an electron accelerator support device and an electron accelerator device, which can simplify the installation steps of the electron accelerator device and reduce the volume of the operating space required during the installation process, and is beneficial to reducing the volume of the shield that houses and protects the electron accelerator device.

[0005] On one hand, this application provides an electron accelerator support device, which includes: a support frame, a connecting structure, and an adjusting structure. The connecting structure is matched with multiple coils of the electron accelerator device to connect the coils to form a coil assembly. The adjusting structure is disposed on the support frame and matched with the connecting structure. When the coil assembly is placed within the support frame, the coil assembly is connected to the adjusting structure via the connecting structure, and the connecting structure is movable relative to the adjusting structure. By adjusting the attitude of the adjusting structure relative to the support frame, the adjusting structure can drive the coil assembly to move relative to the support frame.

[0006] The electron accelerator support device provided in this application, due to the presence of a bracket, provides mounting points and support for other components and the accelerator assembly within the device. It also includes a connection structure that matches the coils in the accelerator assembly, allowing multiple coils to be sequentially and securely connected. Simultaneously, an adjustment structure matching the connection structure is provided on the bracket, enabling the connection structure to move relative to the adjustment structure. During the assembly of the accelerator assembly, multiple coils are sequentially and upwardly fixed to form a coil assembly from the bottom of the bracket using the connection structure. The accelerator tube from the accelerator assembly is then hoisted into and fixed to the coil assembly. The coil assembly is then lifted from the bracket to align with the adjustment structure, connecting the connection structure to the adjustment structure. Finally, adjusting the adjustment structure allows the coil assembly to move relative to the bracket, thereby adjusting the coil assembly to a suitable position.

[0007] Compared to related technologies where each coil is individually fixed to a support before the accelerator tube is hoisted into the coil, the electron accelerator support device provided in this application connects multiple coils to form a single coil assembly via a connecting structure. The accelerator tube is then hoisted, and the coil assembly and accelerator tube are lifted together relative to the support to the installation position. This process eliminates the need to adjust the assembly position of individual coils; instead, the assembly position of the entire coil assembly is adjusted via an adjustment structure. Furthermore, it eliminates the need to hoist the accelerator tube into the already high-positioned coil assembly (reducing the hoisting height of the accelerator tube). Therefore, the electron accelerator support device provided in this application simplifies the installation process of electron accelerator equipment and reduces the volume of the operating space required during installation, thereby reducing the volume of the shielding enclosure for housing and protecting the electron accelerator equipment.

[0008] In one possible implementation of this application, the coil includes a second coil and a third coil, and the connecting structure includes a connecting cylinder and a connecting rod; along the axial direction of the coil assembly, the connecting cylinder is located between the second coil and the third coil, and the connecting rod is connected to the second coil and the third coil respectively, so as to press and fix the second coil and the third coil at both ends of the connecting cylinder, and make the second coil and the third coil coaxial.

[0009] In one possible implementation of this application, the circumferential sidewall of the connecting cylinder has an observation notch.

[0010] In one possible implementation of this application, the coil further includes a first coil, and the connection structure further includes a connecting ring and a fastener. The connecting ring is matched with both the first coil and the second coil and is located between the first coil and the second coil. Along the axial direction of the coil assembly, the fastener fixes the connecting ring and the end of the second coil away from the third coil, and makes the first coil and the second coil coaxial.

[0011] In one possible implementation of this application, the adjustment structure includes a first support member and a first adjustment member. The first support member is axially movably disposed within the bracket via the first adjustment member, and the first support member has a first clearance notch. When the coil assembly is placed within the bracket and the connecting rod is positioned within the first clearance notch, the connecting rod can move axially relative to the bracket until the connecting cylinder is connected to the first support member, thereby restricting the axial movement of the connecting cylinder relative to the bracket.

[0012] In one possible implementation of this application, the adjustment structure further includes a first limiting member, which includes at least two first limiting plates. The at least two first limiting plates are arranged circumferentially on the edge of the clearance notch on the first support member to enclose and form a first limiting notch that matches the connecting cylinder. A portion of the connecting cylinder can move axially relative to the support within the first limiting notch until another portion of the connecting cylinder abuts against the first limiting plate.

[0013] In one possible implementation of this application, the support includes a first carrier having a second clearance notch that matches the acceleration tube of an electron accelerator device; the adjustment structure includes a second adjustment member movably disposed on the first carrier along the radial direction of the coil assembly; when the coil assembly is placed in the support and the acceleration tube is located within the second clearance notch, a third coil is axially connected to the first carrier, and the second adjustment member abuts against the third coil along the radial direction of the coil assembly.

[0014] In one possible implementation of this application, the adjustment structure further includes a second limiting member, which includes at least two second limiting plates. The at least two second limiting plates are arranged circumferentially on the edge of the second clearance notch on the first carrier to enclose and form a second limiting notch that matches the acceleration tube. The end of the third coil away from the second coil abuts against the second limiting plate.

[0015] In one possible implementation of this application, the support includes a third carrier located within the support corresponding to the scanning magnet of the electron accelerator device; the adjustment structure includes a third adjustment component, at least a portion of which is movably disposed on the third carrier along the radial direction of the coil assembly; when the scanning magnet is disposed on the third carrier and abuts against the third adjustment component, by adjusting the position of the third adjustment component relative to the support along the radial direction of the coil assembly, the scanning magnet can be driven to move radially relative to the support.

[0016] Secondly, this application provides an electron accelerator device, which includes: an accelerator assembly and an electron accelerator support device provided in any one of the above-mentioned embodiments. The accelerator assembly includes at least two coils; the at least two coils are fixedly connected by a connecting structure, and the accelerator assembly is mounted on a support via the connecting structure and an adjustment structure.

[0017] The electron accelerator device provided in this application includes the electron accelerator support device provided by any of the above-mentioned methods. Therefore, the steps for installing the electron accelerator device can be simplified, and the volume of the operating space required during the installation of the electron accelerator device can be reduced, thereby reducing the volume of the shield that houses and protects the electron accelerator device.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

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

[0032] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0033] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0034] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0035] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] In recent years, electron irradiation sterilization technology has developed rapidly. Electron irradiation sterilization boasts strong penetrability, ease of operation, and leaves no toxic residues, making it widely used in medical devices, pharmaceuticals, and food sterilization. Electron accelerator equipment can generate high-speed electron beams, which require shielding of sufficient thickness to absorb and reduce potential harm to personnel.

[0037] Sufficient space is required for installing accelerators and replacing components in electron accelerator equipment. For example, the shielded hall of the accelerator body is primarily used for installing the accelerator unit, replacing the accelerator tube and vacuum components, and accommodating hoisting equipment used during component installation and replacement. Since the accelerator tube is located at the center of the accelerator's coil assembly, it must be vertically hoisted into the coil assembly, which is located at the top of the accelerator unit. Therefore, a hoisting operation space at least equal in height to the length of the accelerator tube needs to be reserved above the accelerator unit. However, this reserved hoisting operation space is not needed during normal accelerator operation. Currently, to ensure sufficient installation space, the shielding height is generally two to three times the overall height of the accelerator unit, resulting in significant waste of shielding volume.

[0038] In related technologies, during the installation of the accelerator unit of an electron accelerator, each coil in the accelerator unit needs to be parallel to the ground and coaxial to facilitate the hoisting of the accelerator tube. Furthermore, after the initial installation of the coils, each coil needs to be leveled, which further increases the number of steps involved in installing the electron accelerator. Therefore, it is necessary to change the installation method and support device of the electron accelerator to simplify the installation process and reduce the volume of the operating space required during installation, thereby reducing the volume of the shielding enclosure that houses and protects the electron accelerator.

[0039] Based on this, embodiments of this application provide an electron accelerator system, referring to... Figure 1 and Figure 2 , Figure 1 Schematic diagram of the electron acceleration system structure provided in the embodiments of this application Figure 1 , Figure 2 Schematic diagram of the electron acceleration system structure provided in the embodiments of this application Figure 2 The electron accelerator system includes an electron accelerator device 5 and a shield 6. The shield 6 has a shield cavity 611 that matches the electron accelerator device, and a bracket 1 is fixed inside the shield cavity 611 to fix the electron accelerator device 5 inside the shield cavity 611.

[0040] In this embodiment of the application, the electron accelerator device 5 is used to generate a high-speed electron beam. A shield 6 can be provided on the electron accelerator device 5 to absorb the escaping electrons.

[0041] For example, the shielding body 6 can be configured as a structure including a main hall 61 and a sub-beam labyrinth 62, which can be made of concrete. The internal structure of the main hall 61 and the sub-beam labyrinth 62 can 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 can be provided in the main hall 61, the space of which is larger than the volume of the accelerator device. A mounting hole 612 can be provided at the bottom of the main hall 61 to connect the main hall 61 and the sub-beam labyrinth 62, so that a portion of the accelerator device located in the main hall 61 extends through the mounting hole 612 into the sub-beam labyrinth 62.

[0042] In another example, if the accelerator unit is located at a height of 2.8 meters within the main control room 61, the height of the shielding cavity 611 within the main control room 61 can be set to 5 meters. This not only allows for the installation of the accelerator unit but also reduces the height of the main control room 61, thereby reducing the volume of the shielding body 6.

[0043] In addition, this application embodiment also provides an electron accelerator device 5, referring to... Figure 3 , Figure 3 This is a schematic diagram of the structure of an electron accelerator device provided in an embodiment of this application. The electron accelerator device 5 includes an accelerator assembly and an electron accelerator support assembly. The accelerator assembly includes at least two coils; the at least two coils are fixedly connected by a connecting structure 2, and the accelerator assembly is mounted on the support 1 via the connecting structure 2 and the adjustment structure.

[0044] In this embodiment, the coils in the accelerator device are 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 to fix the multiple coils together to form a coil assembly.

[0045] For example, an adjustment structure matching the connection structure 2 can be provided in the electron accelerator support device, and the coil assembly can move in the adjustment structure 3. The coil assembly can also be fixed in the electron accelerator support device by the adjustment structure 3 to complete the installation of the accelerator device.

[0046] Additionally, this application also provides an electron accelerator support device, referring to... Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the structure of the electron accelerator support device provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of a coil assembly of an electron accelerator device provided in an embodiment of this application. The electron accelerator support device includes: a bracket 1, a connecting structure 2, and an adjusting structure 3. The connecting structure 2 is matched with multiple coils of the electron accelerator device 5 to connect the coils to form a coil assembly. The adjusting structure 3 is disposed on the bracket 1 and matches the connecting structure 2. When the coil assembly is placed inside the bracket 1, the coil assembly is connected to the adjusting structure 3 via the connecting structure 2, and the connecting structure 2 can move relative to the adjusting structure 3. By adjusting the attitude 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 embodiments of this application, such as Figure 3 and Figure 4 As shown, a bracket 1 can be installed in the electron accelerator support device to provide mounting points and support for the electron accelerator support device and the accelerator device, and to fix the accelerator device in the shield 6 through the bracket 1.

[0048] For example, a frame can be provided in the bracket 1. For instance, 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, thus forming a space to accommodate the accelerator device in each frame. The lower frame 11 and the upper frame 12 can be fixedly connected along the long axis of the frame by bolts.

[0049] In this embodiment, the coils in the accelerator device of the electron accelerator equipment 5 are used to generate a changing magnetic field, and multiple coils can be arranged in the accelerator device. In order to connect and fix 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 sequentially fixed and connected to form a coil assembly through the connection structure 2.

[0050] For example, such as Figure 5 As shown, when the accelerator device includes three coils, the connection structure 2 can be configured to include two sets of connection components to sequentially and securely connect the three coils. Furthermore, the connection components can be configured to ensure the three coils are coaxial.

[0051] In the embodiments of this application, such as Figure 4 As shown, an adjustment structure 3 can be provided on the support 1, and at least a portion of the adjustment structure 3 can be configured to move relative to the support 1, thereby adjusting the attitude of the adjustment structure 3 relative to the support 1. The adjustment structure 3 can be configured to match the connecting structure 2. For example, a portion of the connecting structure 2 can be inserted into the adjustment structure 3, and another portion of the connecting structure 2 can abut against the adjustment structure 3.

[0052] For example, refer to Figure 6 , Figure 6 A schematic diagram of the assembly process of the coil assembly of the electron accelerator device provided in the embodiments of this application. Figure 1 During the assembly of the accelerator device, the lower frame 11 can be leveled and fixed inside the shielding body 6. First, the third coil 53 can be placed at the bottom of the lower frame 11. Then, the second coil 52 is fixedly connected to the upper end of the third coil 53 via the connecting structure 2. Next, the first coil 51 is fixedly connected to the upper end of the second coil 52 via the connecting structure 2, thus completing the assembly of the three coils. Then, the accelerating tube 54 in the accelerator device can be hoisted into the coil assembly from above the lower frame 11. Finally, the upper frame 12 is fixed to the lower frame 11 and leveled. During the hoisting process, since the coil assembly is located inside the support 1 and at the bottom of the support 1, the hoisting height of the accelerating tube 54 can be reduced, thereby reducing the reserved height of the shielding cavity 611 inside the shielding body 6.

[0053] 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 embodiments of this application Figure 2 After the accelerator tube 54 is hoisted into the coil assembly, the accelerator 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, so that a part of the connecting structure 2 is inside the adjustment structure 3. Then the attitude of the adjustment structure 3 is adjusted so that the installation position of the accelerator device on the bracket 1 can be adjusted through the adjustment structure 3.

[0054] The electron accelerator support device provided in this embodiment includes a bracket 1, which provides mounting points and support for other components and the accelerator device within the support device. It also includes a connection structure 2 that matches the coils in the accelerator device of the electron accelerator 5, allowing multiple coils to be sequentially and fixedly connected. Simultaneously, an adjustment structure 3 matching the connection structure 2 is provided on the bracket 1, enabling the connection structure 2 to move relative to the adjustment structure 3. During the assembly of the accelerator device, multiple coils are sequentially and upwardly fixedly connected from the bottom of the bracket 1 using the connection structure 2 to form a coil assembly. The accelerator tube 54 is then hoisted into the coil assembly and fixed therein. The coil assembly is then lifted from the bracket 1 to align with the adjustment structure 3, connecting the connection structure 2 and the adjustment structure 3. Finally, adjusting the adjustment structure 3 allows the coil assembly to move relative to the bracket 1, thereby adjusting the coil assembly to a suitable position.

[0055] Compared to related technologies where each coil is individually fixed to the bracket 1 and the accelerating tube 54 is then hoisted into the coil, the electron accelerator support device provided in this application embodiment can connect multiple coils to form an integral coil assembly via the connecting structure 2, then hoist the accelerating tube 54, and finally lift the coil assembly and the accelerating tube 54 together relative to the bracket 1 to the installation position. In this process, there is no need to adjust the assembly position of individual coils; instead, the assembly position of the entire coil assembly is adjusted via the adjusting structure 3. Furthermore, it is not necessary to hoist the accelerating tube 54 into the already high-height coil assembly (reducing the hoisting height of the accelerating tube 54). Therefore, the electron accelerator support device provided in this application embodiment simplifies the installation steps of the electron accelerator device 5 and reduces the volume of the operating space required during the installation of the electron accelerator device 5, thereby reducing the volume of the shield 6 that houses and protects the electron accelerator device 5.

[0056] In some possible embodiments of this application, reference is made to Figure 8 , Figure 8This is a schematic diagram of the structure of the first connecting assembly in the electron accelerator support device provided in the embodiments of this application. The coil includes a second coil 52 and a third coil 53. 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. 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 embodiments of this application, such as Figure 6 and Figure 7 As shown, the accelerator device includes a second coil 52 and a third coil 53, which need to be fixedly connected along the Z-axis. Therefore, a first connecting assembly 21 can be provided for the second coil 52 and the third coil 53 to fix them together.

[0058] For example, such as Figure 8 As shown, a connecting cylinder 211 and multiple connecting rods 212 can be provided in the first connecting assembly 21. For example, the connecting cylinder 211 can be a cylindrical shape with a diameter close to or the same as the diameter of the second coil 52, and abutment rings 2113 matching the second coil 52 and the third coil 53 can be provided at both ends of the connecting cylinder 211. Through holes can be provided on the abutment rings 2113; for example, six corresponding through holes can be provided on each of the two abutment rings 2113 along the circumferential direction C, and these 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 rods 212 can be threaded rods or bolts. Figure 5 and Figure 6 As shown, the third coil 53 can be placed on the third support member 15 inside the bracket 1. The third support member 15 is located at the bottom of the bracket 1. Then, the connecting cylinder 211 is placed above the third coil 53, and the second coil 52 is placed above the connecting cylinder 211. The connecting rod 212 is passed through the second coil 52, the abutment ring 2113 and the third coil 53 in sequence. Finally, the nut is screwed in using a nut that matches the thread on the connecting rod 212, 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 to make the second coil 52 and the third coil 53 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 assembly accuracy requirements.

[0060] In the above embodiment, since a 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. The connecting rod 212 passes 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 sequentially through the connecting rod 212, thereby completing the fixed connection of the second coil 52 and the third coil 53. By setting the machining precision of the connecting cylinder 211, the second coil 52 and the third coil 53 can be placed in a coaxial position after being fixedly connected by the connecting cylinder 211 and the connecting rod 212, thereby reducing the steps required to adjust the coaxiality of the second coil 52 and the third coil 53 during assembly.

[0061] In some possible embodiments of this application, such as Figure 5 and Figure 8 As shown, the circumferential sidewall 2112 of the connecting cylinder 211 has an observation notch 2111.

[0062] In the embodiments of this application, such as Figure 6 As shown, during the process of hoisting the accelerator tube 54 into the coil assembly, it is necessary to control the gap between the accelerator tube 54 and the coil to prevent collision or friction between them. Therefore, an observation notch 2111 can be provided on the connecting cylinder 211 to observe the attitude of the accelerator tube 54 after it enters the coil assembly.

[0063] For example, a through hole can be provided on the circumferential sidewall 2112 of the connecting cylinder 211, serving as an observation notch 2111. For instance, two observation notches 2111 can be provided on the circumferential sidewall 2112 of the connecting cylinder 211, positioned opposite each other in the radial direction X of the coil assembly. Alternatively, three or four equal numbers of observation notches 2111 can be provided on the circumferential sidewall 2112 of the connecting cylinder 211. The observation notch 2111 can be shaped as a rectangular through hole, a circular through hole, an elliptical through hole, etc.

[0064] In the above embodiment, since an observation notch 2111 is provided on the circumferential sidewall 2112 of the connecting cylinder 211, during the process of hoisting the acceleration tube 54 into the coil assembly, the movement state of the acceleration tube 54 in the coil assembly and the gap between the acceleration tube 54 and the inner wall of the coil assembly can be observed through the observation notch 2111. This facilitates the control of the movement path of the acceleration tube 54 through the observation notch 2111, thereby reducing the risk of the acceleration tube 54 colliding with the inner wall of the coil assembly during its descent and also helps to speed up the hoisting of the acceleration tube 54 into the coil assembly.

[0065] In some possible embodiments of this application, such as 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 is matched with 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 end of the second coil 52 away from the third coil 53, and makes the first coil 51 and the second coil 52 coaxial.

[0066] In this embodiment, the accelerator device further includes a first coil 51, and it is necessary to fix the first coil 51 and the second coil 52 together along the Z-axis. Therefore, a second connecting component 22 can be provided for the first coil 51 and the second coil 52 to fix the first coil 51 and the second coil 52 together.

[0067] For example, such as Figure 4 As shown, a connecting ring 221 and a fastener 222 can be provided in the first connecting assembly 21. For example, corresponding through holes can be provided on the first coil 51 and the second coil 52, respectively. These through holes pass through 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, allowing the winding to be wound on them for support. For example, six corresponding through holes can be provided on the first coil 51 and the second coil 52, respectively. Figure 5 As shown, the connecting ring 221 can be cylindrical, with its outer diameter larger than the diameter of the through holes on the first coil 51 and the second coil 52. 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 restrict axial Z-movement between the first coil 51 and the second coil 52. Fasteners 222 can be bolt pairs that match the through holes on the first coil 51 and the second coil 52, to press the first coil 51 and the second coil 52 against both ends of the connecting ring 221.

[0068] In another example, multiple connecting rings 221 can be evenly arranged between the first coil 51 and the second coil 52 along the circumferential direction C of the coil assembly. This means that the corresponding through holes on the first coil 51 and the second coil 52 are evenly distributed 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 using bolts, the coaxiality of the first coil 51 and the second coil 52 can meet the assembly accuracy requirements.

[0069] In the above embodiment, since a 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. Fasteners 222 pass through the through holes on the first coil 51 and the second coil 52, and the first coil 51, connecting ring 221, and second coil 52 can be sequentially fixed by the fasteners 222. By setting the machining precision of the connecting cylinder 211 and the positional precision of the corresponding through holes on the first coil 51 and the second coil 52 for the fasteners 222, the first coil 51 and the second coil 52, after being fixedly connected by the connecting ring 221 and the fasteners 222, can be placed in a coaxial position, thereby reducing the steps required to adjust the coaxiality of the first coil 51 and the second coil 52 during assembly.

[0070] In some possible embodiments of this application, reference is made to Figure 9 , Figure 9 A schematic diagram of the structure of the first adjustment component of the electron accelerator support device provided in an embodiment of this 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 disposed in the bracket 1 along the axial direction Z by the first adjustment member 312. The first support member 311 has a first clearance notch. When the coil assembly is placed in the bracket 1 and the connecting rod 212 is located in the first clearance notch, the connecting rod 212 can move relative to the bracket 1 along the axial direction Z until the connecting cylinder 211 is connected to the first support member 311, thereby restricting the movement of the connecting cylinder 211 relative to the bracket 1 along the axial direction Z.

[0071] In the embodiments of this application, such as Figure 6 As shown, this is after the assembly of the coil assembly and the hoisting of the accelerator tube 54 into the coil assembly are completed. Figure 7 As shown, the coil assembly, together with the acceleration tube 54, can be lifted upwards, allowing the coil assembly and acceleration tube 54 to move from the lower frame 11 to the upper frame 12. To fix the coil assembly within the upper frame 12, a first adjustment component 31 can be provided within the upper frame 12 to fix and adjust the position of the first connecting component 21 within the bracket 1.

[0072] For example, such as Figure 9 As shown, the first adjusting component 31 can be configured to include a first support member 311 and a first adjusting member 312. The structure of the first support member 311 can be configured according to the structure of the upper frame 12. For example, the first support member 311 can be configured as an approximately rectangular plate, and a first clearance notch can be provided on the first support member 311 so that the coil assembly can pass through the first support member 311 through the first clearance notch. Multiple lugs 314 can be provided on the first support member 311, such as one lug 314 at each corner of the rectangular first support member 311 within the upper frame 12. The lugs 314 can be fixed to the columns of the upper frame 12 by bolts. A first adjusting member 312 can be provided between the lugs 314 and the first support member 311. For example, the first adjusting member 312 can be a stud and a nut. Threaded holes matching the studs can be provided on the lugs 314, and a through hole matching the stud can be provided at each corner of the first support member 311. The stud can be connected to the lug 314 along the axial Z-thread of the coil assembly. The first support 311 is threaded through four bolts, and at least two nuts are provided on the same bolt, with the at least two nuts located above and below the first support 311, respectively.

[0073] Thus, as Figure 7 As shown, the first support member 311 can be movably mounted within the bracket 1 via four first adjusting members 312. For example, after the coil assembly is hoisted into the upper frame 12 and the connecting rod 212 is positioned where the first support member 311 is, the first support member 311 can be installed within the bracket 1 via the first adjusting members 312. At this time, the connecting cylinder 211 passes through the first clearance notch of the first support member 311, allowing the coil assembly to move vertically downwards until the abutment ring 2113 on the connecting cylinder 211, which abuts against the second coil 52, abuts against the edge of the first support member 311. The first support member 311 can then support and limit the connecting cylinder 211, that is, support the coil assembly along the axial direction Z of the coil assembly. The position of the first support member 311 relative to the bracket 1 can then be adjusted by adjusting the four first adjusting members 312, thereby adjusting the position of the coil assembly relative to the bracket 1.

[0074] In the above embodiments, since the first support member 311 has a first clearance notch, the coil assembly can be inserted into the first support member 311, and the connecting cylinder 211 can be connected to the first support member 311 to support the coil assembly. Furthermore, the first support member 311 is movably disposed within the bracket 1 via the first adjusting member 312. The position of the first support member 311 relative to the bracket 1 can be adjusted via the first adjusting member 312, which in turn allows the coil assembly to move relative to the bracket 1, facilitating the adjustment of the coil assembly's position relative to the bracket 1 and enabling convenient adjustment of the coil assembly to the desired installation position.

[0075] In some possible embodiments of this application, such as Figure 9 As shown, the adjustment structure 3 also includes a first limiting member 313. The first limiting member 313 includes at least two first limiting plates 3131. The at least two first limiting plates 3131 are arranged along the circumferential direction C of the coil assembly on the edge of the avoidance notch on the first support member 311 to enclose and form a first limiting notch that matches the connecting cylinder 211. A part of the connecting cylinder 211 can move relative to the bracket 1 along the axial direction Z within the first limiting notch until the other part of the connecting cylinder 211 abuts against the first limiting plate 3131.

[0076] In this embodiment of the application, after the connecting cylinder 211 is inserted into the first clearance notch of the first support member 311, in order to facilitate the connection between the connecting cylinder 211 and the first support member 311, a first limiting member 313 can be provided on the first support member 311 to restrict the movement of the connecting cylinder 211 relative to the first support member 311.

[0077] For example, the first limiting member 313 can be configured as an approximate C-shaped clip. For instance, the inner diameter of the first limiting member 313 can be set according to the outer diameter of the circumferential sidewall 2112 of the connecting cylinder 211 and the outer diameter of the abutment ring 2113 of the connecting cylinder 211. The inner diameter of the first limiting member 313 can be larger than the outer diameter of the circumferential sidewall 2112 of the connecting cylinder 211 but smaller than the outer diameter of the abutment ring 2113. A clearance groove corresponding to the connecting rod 212 can be provided on the first limiting member 313. Simultaneously, the outer diameter of the first limiting member 313 can be larger than the inner diameter of the first clearance notch on the first support member 311. The first limiting member 313 can be locked onto the circumferential sidewall 2112 of the connecting cylinder 211 along the radial direction X of the coil assembly. In this way, the lower surface of the first limiting member 313 abuts against the edge of the first clearance notch of the first support member 311, and the abutting ring 2113 of the connecting cylinder 211 abuts against the upper surface of the first limiting member 313, so that the connecting cylinder 211 is located within the first clearance notch of the first limiting member 313.

[0078] In another example, the first limiting member 313 can be configured as a structure of multiple first limiting plates 3131. For example, the first limiting plates 3131 can be configured as an approximately fan-shaped structure. If the first limiting member 313 is configured as two symmetrical fan-shaped rings, the two fan-shaped first limiting members 313 can be locked between the first support member 311 and the abutment ring 2113 of the connecting cylinder 211 along the radial X of the coil assembly.

[0079] In the above embodiments, since a first limiting member 313 is provided between the first support member 311 and the connecting cylinder 211, the movement of the connecting cylinder 211 relative to the first support member 311 can be restricted by the first limiting member 313. Furthermore, the first limiting member 313 is configured to include at least two first limiting plates 3131, which facilitates the insertion of multiple first limiting plates 3131 along the radial direction X of the coil assembly between the first support member 311 and the connecting cylinder 211, thereby enabling rapid positioning and support of the coil assembly within the bracket 1.

[0080] In some possible embodiments of this application, reference is made to Figure 10 , Figure 10 This is a schematic diagram of the structure of the second adjustment component in the electron accelerator support device provided in the embodiments of this application. The support 1 includes a first support member 13, which has a second clearance notch that matches the acceleration tube 54 of the electron accelerator device 5; the adjustment structure 3 includes a second adjustment member 321, which is movably disposed on the first support member 13 along the radial direction X of the coil assembly; when the coil assembly is placed in the support 1 and the acceleration tube 54 is located within the second clearance notch, the third coil 53 is connected to the first support 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 embodiments of this application, such as Figure 4 and Figure 7 As shown, a first support member 13 can be provided in the bracket 1 to provide support for the third coil 53. For example, the first support member 13 can be provided at the connection between the upper frame 12 and the lower frame 11. The first support member 13 can be set as a plate structure, and a second clearance notch can be provided on the first support member 13 so that the coil assembly or the accelerating tube 54 can pass through the first support member 13 through the second clearance notch.

[0082] For example, such as Figure 7 and Figure 10As shown, a second adjusting component 32 can be provided on the first support member 13 to adjust the position of the third coil 53 in the coil assembly relative to the bracket 1 along the radial direction X. For example, the second adjusting component 32 can be configured as a structure of a second fixing block 323 and a second adjusting member 321. Three second fixing blocks 323 can be evenly arranged along the circumferential direction C of the coil assembly on the edge of the second clearance notch on the first support member 13. The second adjusting member 321 can be a bolt, and threaded holes matching the bolts can be provided on the three second fixing blocks 323 respectively. Thus, as... Figure 7 As shown, when the coil assembly is lowered to the point where the third coil 53 is connected to the first support member 13, the third coil 53 can be moved relative to the support member 1 along the radial X direction of the coil assembly by adjusting the positions of the three second adjustment members 321 relative to the first support member 13.

[0083] In the above embodiment, since a first support member 13 is provided in the bracket 1, the coil located at the lowest end of the coil assembly can be supported by the first support member 13. Furthermore, a second adjustment member 321 is provided on the first support member 13, which can drive the coil connected to the first support member 13 to move relative to the bracket 1 along the radial X direction of the coil assembly, thereby facilitating the adjustment of the angle between the axis of the coil assembly and the vertical direction, and thus allowing the axis of the coil assembly to be quickly adjusted to the desired position.

[0084] In some possible embodiments of this application, such as Figure 7 and Figure 10 As shown, the adjustment structure 3 also includes a second limiting member 322. The second limiting member 322 includes at least two second limiting plates 3221. The at least two second limiting plates 3221 are arranged along the circumferential direction C of the coil assembly at the edge of the second clearance notch on the first carrier 13 to enclose and form a second limiting notch that matches the acceleration tube 54. The end of the third coil 53 away from the second coil 52 abuts against the second limiting plate 3221.

[0085] In this embodiment of the application, in order to facilitate supporting the third coil 53 on the first support member 13, a second limiting member 322 can be provided on the first support member 13 to restrict the movement of the third coil 53 relative to the first support member 13.

[0086] For example, the second limiting member 322 can be configured as an approximately annular structure. For instance, the inner diameter of the second limiting member 322 can be set according to the outer diameter of the third coil 53 and the diameter of the accelerating tube 54, such that the inner diameter of the second limiting member 322 is larger than the diameter of the accelerating tube 54 but smaller than the outer diameter of the third coil 53. Simultaneously, the outer diameter of the second limiting member 322 can be larger than the inner diameter of the second clearance notch on the first support member 13. Then, the second limiting member 322 can be engaged between the third coil 53 and the first support member 13 along the axial direction Z of the coil assembly. In this way, the lower surface of the second limiting member 322 abuts against the edge of the second clearance notch of the first limiting member 313, and the lower surface of the third coil 53 abuts against the upper surface of the second limiting member 322.

[0087] In another example, the second limiting member 322 can be configured as a structure of multiple second limiting plates 3221. For example, the second limiting plates 3221 can be configured as an approximately semi-circular structure. If the second limiting member 322 is configured as two symmetrical semi-circular structures, the two semi-circular second limiting members 322 can be locked between the first carrier 13 and the third coil 53 along the radial X of the coil assembly.

[0088] In the above embodiments, since a second limiting member 322 is provided between the first support member 13 and the coil assembly, the movement of the coil assembly relative to the first support member 13 can be restricted by the second limiting member 322. Furthermore, the second limiting member 322 is configured to include at least two second limiting plates 3221, which facilitates the insertion of multiple second limiting plates 3221 radially X-shaped into the space between the first support member 13 and the coil assembly, thereby enabling rapid support of the coil assembly on the first support member 13.

[0089] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the support 1 includes a second support member 14, which is located inside the support 1 at a position corresponding to the acceleration tube 54 of the electron accelerator device 5. The second support member 14 is used to support and fix the acceleration tube 54.

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

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

[0092] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the support 1 includes a third support member 15, which is located inside the support 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, at least a portion of which is movably disposed on the third support member 15 along the radial X of the coil assembly; when the scanning magnet 56 is disposed on the third support member 15 and abuts against the third adjustment component 33, by adjusting the position of the third adjustment component 33 relative to the support 1 along the radial X of the coil assembly, the scanning magnet 56 can be driven to move relative to the support 1 along the radial X.

[0093] In this embodiment of the application, a third support member 15 can be provided at the lower end of the lower frame 11, and the third support member 15 can be configured as a plate-like structure. For example... Figure 3 As shown, the scanning magnet 56 in the electron accelerator device 5 can be mounted on the third support member 15 so that the scanning magnet 56 is connected to the acceleration tube 54 via the vacuum assembly 55. Furthermore, a third adjustment assembly 33 matching the scanning magnet 56 can be mounted on the third support member 15 to adjust and limit the position of the scanning magnet 56 relative to the support 1.

[0094] For example, such as 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. Multiple third fixing blocks 331 can be provided on the third support member 15 along the circumferential direction C of the scanning magnet 56. The third adjustment member 332 can be a bolt, and each third fixing block 331 can have a threaded hole matching the bolt. Thus, as... Figure 3 As shown, when the scanning magnet 56 is placed on the third support member 15, the scanning magnet 56 can be moved relative to the support member 1 along the radial X of the coil assembly by adjusting the position of the third adjustment member 332 around the scanning magnet 56 relative to the third support member 15, thereby allowing the scanning magnet 56 to be in the desired position.

[0095] In the above embodiment, since a third support member 15 is provided in the bracket 1, the mounting point and support of the scanning magnet 56 can be provided by the third support member 15. Furthermore, a third adjustment component 33 is provided on the third support member 15, which can drive the scanning magnet 56 to move relative to the bracket 1 along the radial X direction of the coil assembly, thereby facilitating the adjustment of the position of the scanning magnet 56 in the radial X direction of the coil assembly, so as to quickly adjust the scanning magnet 56 to the desired position.

[0096] In some possible embodiments of this application, such as Figure 3 and Figure 4 As shown, the electron accelerator support device also includes a beam under support assembly 4, which is disposed on the third support member 15. The beam under support assembly 4 is used to support and fix the scanning box 57 of the electron accelerator device 5.

[0097] In this embodiment, a beam support assembly 4 can be provided below the lower frame 11 to mount the scanning box 57 of the electron accelerator device 5 below the scanning magnet 56. For example, the beam support assembly 4 can be configured to include 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 suspended and connected to the lower part of the third support member 15, and the support plate 42 can be connected to the end of the suspension rod 41 away from the third support member 15. In this way, the scanning box 57 can be fixed below the scanning magnet 56 by the support plate 42 and the suspension rod 41, which facilitates the installation of the scanning box 57.

[0098] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
