[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] The following is a reference appendix. Figure 1-8 A support mechanism 100 for auxiliary assembly tooling according to an embodiment of the present invention is described.

[0048] Reference Figure 1 , Figure 2 and Figure 3 According to the first aspect of the present invention, the auxiliary assembly fixture 100 is a support mechanism 100 for mounting a poloidal field magnet.

[0049] Specifically, the support mechanism 100 includes a support platform 10 and a drive mechanism 20. The support platform 10 is used to support the poloidal field magnet; the drive mechanism 20 is used to drive the support platform 10 in a first direction (e.g., Figure 3 (as shown in the front and back directions), second direction (such as...) Figure 3 (as shown in the left and right directions) and third direction (such as...) Figure 3 The movement is indicated by the up and down directions, and the first direction, the second direction, and the third direction intersect each other.

[0050] When installing the poloidal magnet using the support mechanism 100, first place the poloidal magnet on the upper part of the temporary support fixture, then use the drive mechanism 20 to drive the support platform 10 to support the underside of the poloidal magnet. After that, the drive mechanism 20 drives the support platform 10 to lift the poloidal magnet to a suitable height. When it is necessary to adjust the poloidal magnet in the horizontal plane, use the drive mechanism 20 to drive the support platform 10 to move. The support platform 10 drives the poloidal magnet to move in the front-back direction and the left-right direction until the poloidal magnet reaches the suitable installation position. At this time, the installation of the poloidal magnet is completed.

[0051] The support mechanism 100 of the auxiliary assembly tooling of the present invention is provided with a driving mechanism 20. The driving mechanism 20 adjusts the position of the poloidal field magnet by driving the support platform 10. Compared with the existing tooling solutions that can only lift the poloidal field magnet in the vertical direction, the support mechanism 100 of this application can adjust the position of the poloidal field magnet after lifting it. Therefore, in the early stage of installation of the poloidal field magnet, there is no need to perform high-precision positioning of the poloidal field magnet, thereby reducing the installation difficulty of the poloidal field magnet, facilitating the installation of the poloidal field magnet, and effectively improving the installation efficiency. At the same time, the support mechanism 100 has a simple structure, low cost, and is easy to use in batches.

[0052] Furthermore, the support mechanism 100 can adjust the position of the poloidal field magnet according to actual needs. Therefore, the support mechanism 100 of this application can be used to install the poloidal field magnet for different nuclear fusion devices 1, thereby improving the versatility of the support mechanism 100. At the same time, during the installation of the poloidal field magnet, the position of the poloidal field magnet can be adjusted by the drive mechanism 20, thereby improving the positioning accuracy.

[0053] According to an embodiment of the present invention, the support mechanism 100 of the auxiliary assembly tooling is provided with a driving mechanism 20. The driving mechanism 20 adjusts the position of the poloidal field magnet by driving the support platform 10, thereby reducing the installation difficulty of the poloidal field magnet, facilitating the installation of the poloidal field magnet, effectively improving the installation efficiency, and improving the versatility of the support mechanism 100.

[0054] According to some embodiments of the present invention, with reference to Figure 2 and Figure 3 The auxiliary assembly tooling support mechanism 100 further includes: a base plate 30 and a moving platform 40, the moving platform 40 being disposed between the base plate 30 and the support platform 10, and the moving platform 40 being connected to the support platform 10; the drive mechanism 20 includes: a first drive mechanism 21 and a second drive mechanism 22, wherein the first drive mechanism 21 is used to drive the moving platform 40 in a first direction (e.g., Figure 3 (as shown in the front and back directions) and the second direction (such as...) Figure 3 The second drive mechanism 22 is used to drive the support platform 10 in a third direction (such as left and right). Figure 3 The platform 40 moves in the vertical direction shown; or, the first drive mechanism 21 drives the mobile platform 40 to move in the third direction, and the second drive mechanism 22 drives the support platform 10 to move in the first and second directions.

[0055] In this way, the mobile platform 40 and the support platform 10 are set up, and the mobile platform 40 and the support platform 10 move in different directions. The mobile platform 40 and the support platform 10 are driven by different drive mechanisms 20 to realize the adjustment of the poloidal field magnet. This ensures that the poloidal field magnet can move in multiple directions at the same time, thereby effectively improving the installation efficiency.

[0056] Furthermore, a first drive mechanism 21 and a second drive mechanism 22 are provided. The first drive mechanism 21 and the second drive mechanism 22 control different structures to move in different directions, thereby ensuring that the poloidal field magnet can move quickly, which can improve the installation efficiency. At the same time, it can reduce the control difficulty of the support mechanism 100, facilitate the optimization of the control logic, and thus ensure the stability of the operation of the support mechanism 100.

[0057] For example, such as Figure 2 and Figure 3 As shown, a base plate 30 is located below the support platform 10, and a moving platform 40 is located between the base plate 30 and the support platform 10. The moving platform 40 drives the support platform 10 to move. A first drive mechanism 21 is located between the base plate 30 and the moving platform 40, and drives the moving platform 40 to move in the front-back direction and the left-right direction. A second drive mechanism 22 is located between the moving platform 40 and the support platform 10, with its upper and lower ends respectively abutting against the moving platform 40 and the support platform 10. The second drive mechanism 22 drives the support platform 10 to move in the vertical direction. Preferably, the second drive mechanism 22 is a hydraulic cylinder. Hydraulic cylinders have a simple structure, low cost, and are easy to mass-produce.

[0058] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The support mechanism 100 for the auxiliary assembly tooling includes: a fixed bracket 50, the fixed bracket 50 being aligned along a third direction (e.g., Figure 3 Extending in the vertical direction shown, the fixed bracket 50 is located between the movable platform 40 and the support platform 10. The support platform 10 can move relative to the movable platform 40 between a first position and a second position. In the first position, the fixed bracket 50 supports the support platform 10. In the second position, the fixed bracket 50 is separated from the support platform 10.

[0059] In this way, by setting up the fixed bracket 50, when the drive mechanism 20 does not move the support platform 10, the fixed bracket 50 provides support for the support platform 10, thereby ensuring the stability of the support platform 10. At the same time, when the drive mechanism 20 drives the support platform 10, the fixed bracket 50 separates from the support platform 10, thereby enabling the support platform 10 to lift the poloidal field magnet without being restricted by the fixed bracket 50, and thus ensuring the lifting height of the support platform 10 in the third direction.

[0060] For example, such as Figure 2 and Figure 3 As shown, the fixed bracket 50 extends in the vertical direction. The lower end of the fixed bracket 50 is fixed on the mobile platform 40, and the upper end of the fixed bracket 50 abuts against the lower surface of the support platform 10. Multiple fixed brackets 50 are provided, and the multiple fixed brackets 50 are arranged at intervals along the circumference of the mobile platform 40.

[0061] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The first drive mechanism 21 includes: a first drive member 211 and a second drive member 212, wherein the first drive member 211 is used to drive the mobile platform 40 in a first direction (e.g., Figure 3 The second drive unit 212 is used to drive the moving platform 40 in the second direction (as shown in the forward and backward direction). Figure 3 The mobile platform 40 moves in the left and right directions (as shown). Thus, the first drive unit 211 and the second drive unit 212 drive the mobile platform 40 to move in different directions, allowing different drive units to be controlled according to actual needs, thereby reducing control difficulty and facilitating the movement of the mobile platform 40.

[0062] For example, such as Figure 2 and Figure 3 As shown, three of each of the first driving component 211 and the second driving component 212 are arranged, with the first driving component 211 and the second driving component 212 spaced apart along the circumference of the moving platform 40. Preferably, both the first driving component 211 and the second driving component 212 are hydraulic cylinders. Hydraulic cylinders have a simple structure, low cost, and are easy to use in batches.

[0063] According to a second aspect embodiment of the present invention, an auxiliary assembly fixture 1000 is provided, referring to... Figure 1 , Figure 2 and Figure 3 The auxiliary assembly fixture 1000 is used to assist in the installation of the poloidal field magnet on the nuclear fusion equipment. The auxiliary assembly fixture 1000 includes the support mechanism 100 of the auxiliary assembly fixture in the first aspect of this embodiment.

[0064] According to an embodiment of the present invention, the auxiliary assembly fixture 1000 is provided with a support mechanism 100 of the auxiliary assembly fixture of the first aspect of the present embodiment, and a driving mechanism 20 is provided. The driving mechanism 20 adjusts the position of the poloidal field magnet by driving the support platform 10, thereby reducing the installation difficulty of the poloidal field magnet, facilitating the installation of the poloidal field magnet, effectively improving the installation efficiency, and improving the versatility of the support mechanism 100.

[0065] According to some embodiments of the present invention, with reference to Figure 2 and Figure 3The number of poloidal magnets is multiple, that is, there can be two, three or four or more poloidal magnets. All the poloidal magnets are arranged in a ring and are spaced apart radially.

[0066] The auxiliary tooling includes multiple support components. That is, the auxiliary tooling may include two, three, four or more support components. The multiple support components correspond one-to-one with multiple poloidal magnets. Each support component includes multiple support mechanisms 100. That is, each support component may include two, three or four or more support mechanisms 100. The multiple support mechanisms 100 of each support component are arranged at circumferential intervals along the corresponding poloidal magnet to jointly support the corresponding poloidal magnet.

[0067] In this way, different support components support the corresponding poloidal field magnets. By setting up multiple sets of support components, multiple poloidal field magnets can be installed simultaneously, thereby ensuring the assembly efficiency of the nuclear fusion device 1. At the same time, controlling different support components can drive different poloidal field magnets to move, thereby reducing the error rate, which in turn can effectively reduce the control difficulty and improve the installation efficiency.

[0068] For example, such as Figure 2 and Figure 3 As shown, there are three poloidal magnets, all of which are ring-shaped and arranged radially with inward and outward spacing. The auxiliary tooling includes three support components, each of which corresponds to one poloidal magnet, and each support component includes multiple support mechanisms 100.

[0069] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The number of poloidal field magnets is three, and the number of support components is three, namely: first auxiliary component 200, second auxiliary component and third auxiliary component. The first auxiliary component 200, second auxiliary component and third auxiliary component are arranged in sequence from the outside to the inside along the radial direction of the poloidal field magnets.

[0070] In this way, different auxiliary components can be used to install different poloidal magnets, allowing multiple poloidal magnets to be installed simultaneously, thereby effectively improving installation efficiency.

[0071] For example, such as Figure 2 and Figure 3 As shown, the second auxiliary component is located radially inside the first auxiliary component 200, and the third auxiliary component is located radially inside the second auxiliary component.

[0072] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3The first auxiliary component 200 includes multiple support mechanisms 100, each of which is a first support mechanism 210. The first auxiliary component 200 also includes multiple support columns 220, meaning that the first auxiliary component 200 may include two, three, four, or more support columns 220, with the support columns 220 extending along a third direction (e.g., ...). Figure 3 Extending in the vertical direction shown, multiple support columns 220 are arranged at intervals along the circumference of the poloidal field magnet and correspond one-to-one with multiple first support mechanisms 210. The first support mechanism 210 is supported on the upper side of the corresponding support column 220 (e.g., ...). Figure 3 (The upper side of the support column 220 shown).

[0073] Thus, the support columns 220 provide an installation position for the first support mechanism 210, facilitating its arrangement. Simultaneously, due to the limitation of the hydraulic cylinder stroke of the first support mechanism 210, the support columns 220 reduce the stroke distance, ensuring the first support mechanism 210 can properly contact the poloidal magnet and thus guarantee its normal operation. Furthermore, the multiple support columns 220 are arranged circumferentially around the poloidal magnet, allowing the multiple first support mechanisms 210 to be arranged circumferentially as well. This ensures the multiple first support mechanisms 210 drive the poloidal magnet to move circumferentially, guaranteeing the smoothness of its movement and effectively preventing it from swaying or falling off the first support mechanism 210.

[0074] For example, such as Figure 2 and Figure 3 As shown, the first auxiliary component 200 includes eight first support mechanisms 210 and eight support columns 220. Each support column 220 has a first support mechanism 210 on its upper side, and the eight support columns 220 are arranged at intervals along the circumference of the poloidal field magnet.

[0075] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 5 The multiple support mechanisms 100 of the second auxiliary component are all second support mechanisms 300, and the multiple support mechanisms 100 of the third auxiliary component are all third support mechanisms 400. The auxiliary assembly fixture 1000 also includes a support base 500, which is located radially inside the multiple support columns 220. The multiple second support mechanisms 300 and the multiple third support mechanisms 400 are all supported on the support base 500. In this way, the support base 500 can provide installation positions for the second support mechanisms 300 and the third support mechanisms 400, thereby facilitating the arrangement of the second support mechanisms 300 and the third support mechanisms 400.

[0076] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 5 The support base 500 includes a central base 510 and multiple connecting plates 520. That is, the support base 500 may include two, three, four, or more connecting plates 520. The central base 510 is positioned along the vertical direction (e.g., ...). Figure 5 (As shown in the vertical direction); multiple connecting plates 520 are arranged at intervals along the circumference of the central seat 510, with one end of the connecting plate 520 (as shown in the vertical direction) extending; Figure 2 The connecting plate 520 shown has one end facing the center seat 510 connected to the center seat 510, and the other end (such as...) Figure 2 The end of the connecting plate 520 away from the center seat 510 extends radially outward along the pole field magnet. Multiple second support mechanisms 300 correspond one-to-one with multiple connecting plates 520 and are supported on the other end of the corresponding connecting plate 520.

[0077] In this way, the central seat 510 can provide support for one end of the connecting plate 520, thereby facilitating the arrangement of the connecting plate 520. At the same time, the connecting plate 520 can provide a fixed position for the second support mechanism 300, thereby facilitating the arrangement of the second support mechanism 300. In addition, multiple connecting plates 520 are arranged at intervals around the central seat 510, and the connecting plates 520 correspond to the second support mechanism 300, so that the second support mechanism 300 can support the poloidal field magnet around the poloidal field magnet, thereby ensuring the stability of the second support mechanism 300 in supporting the poloidal field magnet.

[0078] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, the center seat 510 extends vertically, with its lower end supported on the ground. Connecting plates 520 extend radially from the center seat 510, with one end of the connecting plate 520 facing the center seat 510 and connected to its upper end. There are eight connecting plates 520 arranged at intervals around the circumference of the center seat 510. A second support mechanism 300 is positioned at the end of each connecting plate 520 away from the center seat 510, and each connecting plate 520 is equipped with a second support mechanism 300. Preferably, the center seat 510 is provided with multiple reinforcing ribs 5101, thereby strengthening the center seat 510 and effectively preventing damage.

[0079] According to some optional embodiments of the present invention, refer to Figure 2 , Figure 3 and Figure 5The support base 500 also includes a connecting beam 530, which extends circumferentially along the center base 510 and connects between two adjacent connecting plates 520, wherein a portion of the plurality of third support mechanisms 400 is supported on the connecting plate 520 and another portion is supported on the connecting beam 530.

[0080] In this way, by setting up the connecting beam 530, the arrangement position of the third support mechanism 400 can be reasonably selected according to the actual situation, thereby ensuring that the third support mechanism 400 can stably support the poloidal field magnet, and thus ensuring the smooth movement of the poloidal field magnet. At the same time, the connecting beam 530 has a simple form and is easy to install, thereby improving the installation efficiency of the auxiliary assembly tooling 1000.

[0081] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, a connecting beam 530 is provided between two adjacent connecting plates 520. The connecting beam 530 extends circumferentially along the center seat 510. There are three third support mechanisms 400. One of the third support mechanisms 400 is installed on the upper side of the connecting beam 530, and the other two third support mechanisms 400 are located on the upper side of different connecting plates 520. The three third support mechanisms 400 are arranged at intervals along the circumferential direction of the center seat 510.

[0082] According to some embodiments of the present invention, with reference to Figure 2 and Figure 3 The auxiliary assembly fixture 1000 includes a connector 600, and a first auxiliary component 200 is connected to the end of the connecting plate 520 away from the center seat 510 via the connector 600. Thus, the first auxiliary component 200 is connected to the center seat 510 as a whole via the connector 600, thereby ensuring the stability of the entire auxiliary assembly fixture 1000 and effectively preventing it from tipping over or tilting during assembly work.

[0083] According to some optional embodiments of the present invention, refer to Figure 2 and Figure 3 The connecting plate 520 and the support column 220 are arranged alternately along the circumference of the center seat 510. Each support column 220 is connected to two adjacent connecting plates 520 through a connector 600. This ensures the reliability of the connection between the support column 220 and the connecting plate 520, effectively prevents the support column 220 from separating from the connecting plate 520, and thus ensures the overall stability of the auxiliary assembly fixture 1000.

[0084] For example, such as Figure 2 and Figure 3As shown, eight connecting plates 520 and eight support columns 220 are arranged alternately along the circumference of the central seat 510, and each support column 220 is connected to two adjacent connecting plates 520 through a connector 600.

[0085] According to some embodiments of the present invention, with reference to Figure 2 The connector 600 is an anchor cable. Therefore, the anchor cable structure is simple, low-cost, and easy to mass-produce. At the same time, the anchor cable structure has high strength, thus ensuring the stability of the connection between the support column 220 and the connecting plate 520.

[0086] According to some embodiments of the present invention, with reference to Figure 2 and Figure 4 The lower end of the support column 220 is provided with a support leg 2201, which is screwed to the Dewar base 3000.

[0087] The following is for reference. Figures 1-8 An auxiliary assembly fixture 1000 according to an embodiment of the present invention is described.

[0088] According to an embodiment of the present invention, the auxiliary assembly fixture 1000, such as Figure 1 As shown, the auxiliary tooling is used to assist in the installation of the poloidal field magnets on the nuclear fusion equipment. There are three poloidal field magnets, namely the first poloidal field magnet 2100, the second poloidal field magnet 2200 and the third poloidal field magnet 2300. The first poloidal field magnet 2100, the second poloidal field magnet 2200 and the third poloidal field magnet 2300 are all ring-shaped and arranged radially from the outside to the inside at intervals.

[0089] The support mechanism 100 of the auxiliary assembly tooling includes three support components, namely a first auxiliary component 200, a second auxiliary component, and a third auxiliary component. Specifically, the first auxiliary component 200 includes: eight first support mechanisms 210 and eight support columns 220. The support columns 220 extend in the vertical direction, and the lower end of the support column 220 is provided with a support leg 2201. The support leg 2201 is screwed to the Dewar base 3000. The eight support columns 220 are arranged at intervals along the circumference of the first poloidal field magnet 2100 and correspond one-to-one with the multiple first support mechanisms 210. The first support mechanism 210 is supported on the upper side of the corresponding support column 220. The second auxiliary component includes eight second support mechanisms 300. The eight second support mechanisms 300 are arranged at intervals along the circumference of the second poloidal field magnet 2200. The second auxiliary component is located radially inside the first auxiliary component 200. The third auxiliary component includes eight third support mechanisms 400. The eight third support mechanisms 400 are arranged at intervals along the circumference of the third poloidal field magnet 2300. The third auxiliary component is located radially inside the second auxiliary component.

[0090] The auxiliary assembly fixture 1000 also includes a support base 500, which is located radially inside the eight support columns 220. Eight second support mechanisms 300 and two third support mechanisms 400 are all supported on the support base 500. The support base 500 includes a central base 510 and eight connecting plates 520. The central base 510 extends vertically, and the eight connecting plates 520 are arranged circumferentially around the central base 510. One end of each connecting plate 520 facing the central base 510 is connected to the central base 510, and the other end of each connecting plate 520 away from the central base 510 extends radially outward along the second poloidal field magnet 2200. The eight second support mechanisms 300 correspond one-to-one with the eight connecting plates 520 and are supported on the corresponding connecting plate 520 at the end away from the central base 510.

[0091] The support base 500 also includes a connecting beam 530, which extends circumferentially along the center base 510 and connects between two adjacent connecting plates 520, wherein one of the two third support mechanisms 400 is supported on the connecting plate 520 and the other third support mechanism 400 is supported on the connecting beam 530.

[0092] The auxiliary assembly fixture 1000 also includes a connector 600. The first auxiliary component 200 is connected to the end of the connecting plate 520 away from the center seat 510 through the connector 600. The connecting plate 520 and the support column 220 are arranged alternately along the circumference of the center seat 510. Each support column 220 is connected to two adjacent connecting plates 520 through the connector 600.

[0093] The first support mechanism 210, the second support mechanism 300, and the third support structure are all composed of multiple support mechanisms 100. Each support mechanism 100 includes a support platform 10, a drive mechanism 20, a base plate 30, a moving platform 40, and a fixed bracket 50. Specifically, the base plate 30, the moving platform 40, the fixed bracket 50, and the support platform 10 are arranged sequentially from bottom to top. The lower end of the fixed bracket 50 is connected to the moving platform 40, and the upper end of the fixed bracket 50 is supported on the lower side of the support platform 10. The support platform 10 is used to support the poloidal field magnet.

[0094] The drive mechanism 20 includes a first drive mechanism 21 and a second drive mechanism 22. The first drive mechanism 21 is located between the base plate 30 and the moving platform 40. The first drive mechanism 21 includes a first drive member 211 and a second drive member 212. The first drive member 211 is used to drive the moving platform 40 to move in the front-back direction, and the second drive member 212 is used to drive the moving platform 40 to move in the left-right direction. The second drive mechanism 22 is located on the moving platform 40. The lower end of the second drive mechanism 22 is fixed on the moving platform 40, and the upper end of the second drive mechanism 22 abuts against the lower side of the support platform 10. The second drive mechanism 22 is used to drive the support platform 10 to move relative to the moving platform 40 in the up-down direction.

[0095] When assembling the poloidal field magnets using the auxiliary assembly fixture 1000, the third poloidal field magnet 2300, the second poloidal field magnet 2200, and the first poloidal field magnet 2100 are first hoisted from the inside out and placed on the support platform 10 of the auxiliary assembly fixture 1000 of the Dewar base 3000, such as the support platform 10 of the first support mechanism 210 of the first auxiliary component 200. After the vacuum chamber sector and the circumferential field magnets are fully aligned, the lifting and assembly work is performed. Then, the positions of the bottom first poloidal field magnet 2100, the second poloidal field magnet 2200, and the third poloidal field magnet 2300 are measured. The plane position of the poloidal field magnets is adjusted by adjusting the horizontal adjustment components on the auxiliary assembly fixture 1000. Afterward, the first poloidal field magnet 2100 is lifted from the outside in, as shown in the image. Figure 6 As shown, the second drive mechanism 22 of the four or six evenly distributed first support mechanisms 210 of the first auxiliary component 200 is raised to lift the first poloidal magnet 2100 to a certain height. A lifting beam is placed on the support platform 10 of the remaining first support mechanism 210 of the first auxiliary component 200. The support platform 10 of the first support mechanism 210 with the lifting beam is raised to contact the first poloidal magnet 2100. The two symmetrical first support mechanisms 210 without lifting beams are lowered and separated from the first poloidal magnet 2100. Lifting beams are then placed on the upper part of these two first support mechanisms 210 and raised to contact the first poloidal magnet 2100. The steps are repeated, and the stroke of all the first support mechanisms 210 is increased by alternately placing lifting beams.

[0096] Then, the first driving component 211 operates, driving the moving platform 40 to move in the front-to-back direction. The moving platform 40 drives the support platform 10 to move in the front-to-back direction. The support platform 10 drives the first poloidal magnet 2100 to move in the front-to-back direction via the lifting beam. Then, the second driving component 212 operates, driving the moving platform 40 to move in the left-to-right direction. The moving platform 40 drives the support platform 10 to move in the left-to-right direction. The support platform 10 drives the first poloidal magnet 2100 to move in the left-to-right direction via the lifting beam until the first poloidal magnet 2100 reaches the designated installation position. At this time, the auxiliary installation work of the first poloidal magnet 2100 is completed.

[0097] According to the lifting method of the poloidal field magnet, such as Figure 7 As shown, the lifting and assembly of the second poloidal field magnet 2200 is completed. However, the third poloidal field magnet 2300 is smaller in size and has only three support points, making it impossible to use the conventional alternating lifting method, such as... Figure 8As shown, first, a long screw structure is fixed on the circumferential field magnet at the corresponding fixed position, and passes through the lower clamping plate of the third poloidal field magnet 2300. Then, the third auxiliary component is activated to raise the third poloidal field magnet 2300. A nut is inserted into the lower part of the screw and tightened to the position of the lower clamping plate, temporarily suspending the third poloidal field magnet 2300. The three third support mechanisms 400 are lowered, and a lifting beam is placed on top. The height of the third poloidal field magnet 2300 is further increased while the nut is tightened. The steps are repeated until the third poloidal field magnet 2300 is raised to the nominal position. Finally, the long screw structure is replaced with the final mounting bolt. At this point, the installation of the first poloidal field magnet 2100, the second poloidal field magnet 2200, and the third poloidal field magnet 2300 is completed.

[0098] The auxiliary assembly fixture 1000 of this embodiment is provided with a support mechanism 100 of the auxiliary assembly fixture of the first aspect of this embodiment, and a drive mechanism 20. The drive mechanism 20 adjusts the position of the poloidal field magnet by driving the support platform 10, thereby reducing the installation difficulty of the poloidal field magnet, facilitating the installation of the poloidal field magnet, effectively improving the installation efficiency, and improving the versatility of the support mechanism 100.
