[0041] In addition, the features defined as 'first','second' can explicitly or implicitly include one or more of the features, for distinguishing the features described, without order, without priority.

[0042] In the description of the present application, the meaning of 'a plurality of' is two or more, unless otherwise specified.

[0043] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms'mounting', 'connecting', 'connection' should be understood broadly, for example, can be fixedly connected, or detachably connected, or integrally connected; can be mechanically connected, or electrically connected; can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] The support device of the nuclear fusion device pre-assembly of the embodiment of the present application can be applied to a nuclear fusion device, which can include a magnet, a vacuum chamber cold shield and a vacuum chamber, and the magnet, the vacuum chamber cold shield and the vacuum chamber are fixedly connected to form a whole in a ring shape. The composition and operation of the nuclear fusion device are known to those skilled in the art, and are not described here.

[0045] In a nuclear fusion device, such as a tokamak device, the magnets, the vacuum chamber and the vacuum chamber cold shield constitute a toroidal structure, and in the construction process, 1 / 8 sector area of the toroidal structure, i.e., 1 / 8 magnets, 1 / 8 vacuum chamber and 1 / 8 vacuum chamber cold shield are first assembled to form a pre-assembled component. Figure 1 and Figure 2 The support device 100 of the pre-assembled component of the nuclear fusion device according to the embodiments of the present application is used for supporting the TF magnets at the bottom of the pre-assembled component 200.

[0046] The support device 100 of the pre-assembled component of the nuclear fusion device according to the embodiments of the present application is described below with reference to Figures 1-11

[0047] As shown in Figure 3 and Figure 4 The support device 100 of the pre-assembled component of the nuclear fusion device according to the embodiments of the present application comprises a first support section 10, a second support section 20 and an adjustable support section 30 which are detachably connected in sequence along a first direction; the adjustable support section 30 comprises a first adjusting part 31, a second adjusting part 32 and a lifting part 33 which are connected in sequence along the first direction, the first adjusting part 31 is connected to the second support section 20 and can drive the second adjusting part 32 to adjust along a second direction, the second adjusting part 32 can drive the lifting part 33 to adjust along a third direction, and the lifting part 33 can be adjusted up and down along the first direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0048] The first support section 10 can be the basis of the support device 100 of the entire pre-assembled component of the nuclear fusion device, and has a high height and a heavy weight, and is used for being fixed to the embedded parts in the main hall. The shape of the first support section 10 can be but is not limited to a cylinder, a cuboid, a polygonal prism or other special-shaped structures and the like. For example, as shown in Figure 4 The shape of the first support section 10 is a cylinder, has high torsional resistance and rigidity, and has a simple structure and is easy to process and manufacture.

[0049] The second support section 20 can be a component used for connecting the first support section 10 and the adjustable support section 30, and has a similar shape to the first support section 10. The second support section 20 can be but is not limited to an alloy steel, a stainless steel, an aluminum alloy and a composite material and the like.

[0050] ​The adjustable support section 30 can refer to a component for adjusting the support position, and can realize the position in the three directions of the first direction, the second direction and the third direction. The connection mode of the adjustable support section 30 and the second support section 20 can be, but is not limited to, clamping, bolt connection, riveting mode, etc. In the above technical solution, the adjustable support section 30 includes the first adjusting part 31, the second adjusting part 32 and the lifting part 33 connected in sequence along the first direction. The first adjusting part 31 can refer to a component connected to the second support section 20 and having an adjusting stroke in the second direction. The second adjusting part 32 can refer to a component having an adjusting stroke in the third direction. The lifting part 33 can refer to a component having an adjusting stroke in the first direction. The first adjusting part 31, the second adjusting part 32 and the lifting part 33 can be an electric adjusting mechanism or a manual adjusting mechanism. Among them, referring to Figure 3 , as an example, the "first direction" can refer to the up-down direction, the "second direction" can refer to the front-back direction, and the "third direction" can refer to the left-right direction.

[0051] It can be understood that since the support device 100 of the nuclear fusion device pre-assembly has large volume and weight, and the main hall of the nuclear fusion device has many components and limited space, it is difficult to hoist the complete nuclear fusion device pre-assembly support device 100 to the main hall and inconvenient to operate. Since the first support section 10 and the second support section 20 are detachable, they can be transported separately to the site, and then the first support section 10 and the second support section 20 are installed on site. For example, the height of the first support section 10 can be close to two meters, and the weight can be close to two tons, which can be transported by a forklift or the like first, and fixed to the embedded part of the main hall. The second support section 20 and the adjustable support section 30 can be fixed and connected before hoisting and positioning. Then the second support section 20 and the adjustable support section 30 are hoisted, hoisted onto the second support section 20 through a sling and a shackle, and adjusted and fixed after falling into the first support section 10 by slowly moving horizontally to ensure that the vacuum chamber cold screen is not collided.

[0052] When the pre-assembled component 200 needs to be supported, since the first support section 10 is first fixed to the embedded part in the main hall, the first support section 10 and the TF magnet at the bottom of the pre-assembled component 200 can not need to maintain high position accuracy, which facilitates the on-site quick installation and fixation of the first support section 10, and then the accurate support position adjustment is performed through the adjustable support section 30. Specifically, the first adjusting part 31 can be finely adjusted along the radial direction (i.e., the second direction) of the pre-assembled component 200, the second adjusting part 32 can be finely adjusted along the circumferential direction (i.e., the third direction) of the pre-assembled component 200, and the lifting part 33 can be finely adjusted along the height direction (i.e., the first direction) of the pre-assembled component 200, so that the lifting part 33 can be supported at the target position of the TF magnet at the bottom of the pre-assembled component 200, and the pre-assembled component 200 is stably and reliably supported, thereby ensuring the position accuracy of the pre-assembled component 200 in the subsequent assembly process and preventing the pre-assembled component 200 from being displaced.

[0053] According to the support device 100 of the pre-assembled component of the nuclear fusion device in the embodiment of the present application, the support device 100 of the pre-assembled component of the nuclear fusion device is set as the detachable first support section 10, the second support section 20 and the adjustable support section 30, so that the large-size and heavy pre-assembled component of the nuclear fusion device can be conveniently transported to the main hall, and the on-site arrangement of the support device 100 of the pre-assembled component of the nuclear fusion device is facilitated. The adjustable support section 30 is set as the first adjusting part 31, the second adjusting part 32 and the lifting part 33, the adjustable support section 30 can realize three-degree-of-freedom adjustment, can be aligned to the TF magnet at the bottom of the pre-assembled component 200, and better supports the pre-assembled component 200, which is beneficial to improve the position accuracy of the pre-assembled component 200 and further improve the reliability of the installation of the nuclear fusion device.

[0054] In some embodiments of the present application, with reference to Figure 5 The lifting part 33 includes a lifting part body 331, a support seat 332 and a limiting piece 333, the lifting part body 331 is arranged on the second adjusting part 32; the support seat 332 is connected with the lifting end 3311 of the lifting part body 331 and is provided with a first positioning column 33201; and the limiting piece 333 is arranged on the second adjusting part 32 and cooperates with the support seat 332 to limit the rotation of the support seat 332 around the first direction.

[0055] The lifting part body 331 can be a component that can be stretched and contracted along the first direction, and can be but is not limited to a hydraulic cylinder, a hydraulic rod, an electric push rod, an electric cylinder, a lead screw and the like. The limiting piece 333 can be a component for limiting the rotation of the support seat 332 around the first direction, and can be but is not limited to a limiting pin, a limiting block, a shell and the like. The first positioning column 33201 can be but is not limited to a positioning round pin, a prism and the like.

[0056] In the technical scheme, the first positioning column 33201 can cooperate with the hole on the TF magnet, so that the pre-assembled component 200 and the lifting part 33 are connected together to better support the pre-assembled component 200. The support seat 332 can make the lifting part 33 not contact the TF magnet, and the limiting piece 333 can limit the rotation of the support seat 332 around the first direction, so as to reduce the risk that the lifting part main body 331 causes the pre-assembled component 200 to slightly rotate around the first direction in the process of jacking up the pre-assembled component 200, and the position reliability of the pre-assembled component 200 can be improved.

[0057] In some embodiments of the present application, with reference to Figures 5 to 7 The limiting piece 333 has a limiting space 333a inside, and an end of the limiting space 333a away from the second adjusting part 32 is open; the support seat 332 includes a support plate 3321 and a sliding shell 3322, the support plate 3321 connects the lifting end 3311 and the sliding shell 3322, the sliding shell 3322 is open on a side close to the second adjusting part 32, the circumferential direction of the sliding shell 3322 and the circumferential direction of the limiting space 333a are fitted, and the shell wall of the sliding shell 3322 cooperating with the limiting space 333a at least partially forms a flat wall.

[0058] The limiting piece 333 can be a shell structure, or a structure composed of multiple components and surrounding the limiting space 333a. For example, with reference to Figure 5 The limiting piece 333 can be assembled by multiple I-beams, and the multiple I-beams jointly define the limiting space 333a.

[0059] In the technical scheme, the circumferential direction of the sliding shell 3322 and the circumferential direction of the limiting space 333a are fitted, which has a guiding effect. Since the pre-assembled component 200 has a large volume and a large weight, using this scheme can improve the reliability and stability of the lifting of the lifting part main body 331, and can also improve the overall structural strength of the lifting part 33 and improve the reliability.

[0060] The shell wall of the sliding shell 3322 cooperating with the limiting space 333a at least partially forms a flat wall, that is, at least one flat wall surface of the limiting space 333a and the circumferential side of the sliding shell 3322 can form a surface contact constraint to realize the cooperation of the limiting piece 333 and the sliding shell 3322, and limit the rotation of the support plate 3321 around the first direction. Compared with the traditional key groove or pin structure, the contact area of the above scheme is larger, the anti-torsion ability is stronger, the effect of avoiding the rotation of the support seat 332 around the first direction is better, and the reliability of the support device 100 of the pre-assembled component of the nuclear fusion device can be better improved. The circumferential shape of the sliding shell 3322 and the limiting space 333a around the first direction can be rectangular, triangular, sector-shaped or semicircular, etc.

[0061] In some embodiments of the present application, with reference to Figures 6 to 8The limiting piece 333 is provided with a strip-shaped hole 333b extending along the first direction, the sliding shell 3322 is provided with a first threaded hole 3322a, and the lifting part 33 further comprises a first bolt 334 which is arranged in the strip-shaped hole 333b and is screwed with the first threaded hole 3322a.

[0062] The strip-shaped hole 333b can be multiple, such as two, three, four, five or the like.

[0063] In the above technical solution, the strip-shaped hole 333b extends along the first direction, which can provide guidance in the first direction. Since the support seat 332 itself has a large weight and size, the strip-shaped hole 333b and the first bolt 334 can facilitate the installation of the sliding shell 3322 and the limiting piece 333. In addition, after the lifting part main body 331 is lifted into position, the first bolt 334 can be tightened on the outside of the limiting piece 333, so that the sliding shell 3322 and the limiting piece 333 are locked, which can reduce the risk of the lifting part main body 331 resetting in the first direction, and can further improve the support reliability of the support device 100 of the pre-assembly component 200 of the nuclear fusion device.

[0064] In some embodiments of the present application, with reference to Figure 5 , Figure 9 and Figure 10 , the second support section 20 is provided with a first limiting groove 20a; the first adjusting part 31 comprises a first fixed plate 311, a first guide block 312, a first moving seat 313 and a first adjusting piece 314, the first fixed plate 311 is arranged in the first limiting groove 20a and is screwed with the second support section 20; both ends of the first fixed plate 311 in the third direction are provided with the first guide block 312, a first guide groove 31a is defined between the first guide block 312 and the first fixed plate 311, the first guide block 312 is provided with a plurality of second bolts 3121 which are arranged at intervals along the second direction, and the second bolts 3121 can lock the first moving seat 313 in the first direction; part of the first moving seat 313 is slidingly fitted in the first guide groove 31a; both ends of the first fixed plate 311 in the second direction are provided with the first adjusting piece 314, and the first adjusting piece 314 can drive the first moving seat 313 to move along the second direction.

[0065] The first limiting groove 20a can limit the first fixed plate 311, avoiding the first fixed plate 311 from moving relative to the second support section 20. The first limiting groove 20a can limit the first fixed plate 311 along the third direction, or along the third direction and the second direction. The first fixed plate 311 can be nested with the second support section 20 through the first limiting groove 20a, enhancing the connection reliability of the first fixed plate 311 and the second support section 20.

[0066] The first guide block 312 can be L-shaped, and the length in the second direction is less than or equal to the length of the first fixed plate 311. The first adjusting member 314 can be, but is not limited to, a screw rod, a bolt, a jackscrew, a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0067] It can be understood that the first moving seat 313 has a certain gap with the first guide block 312 in the first direction, and the first moving seat 313 can be driven to move along the second direction on the first guide groove 31a by the first adjusting member 314, so as to realize the fine adjustment of the second adjusting part 32 and the lifting part 33 along the second direction. After the first adjusting member 314 is adjusted, the first moving seat 313 can be limited in the second direction and the first direction by screwing the second bolt 3121, so that the first moving seat 313 is pressed on the first fixed plate 311, and the first adjusting part 31 is locked in the current position.

[0068] In the above technical solution, the first adjusting part 31 with the above structure can have high adjustment accuracy, can improve the adjustment reliability of the entire first adjusting part 31, and can lock the first adjusting part 31 after adjustment, so as to prevent loosening in the later period, and can improve the support reliability and stability of the support device 100 of the pre-assembly component 200 of the nuclear fusion device.

[0069] In some embodiments of the present application, with reference to Figure 5 , Figure 7 and Figure 9 , the first moving seat 313 is provided with a second limiting groove 313a; the second adjusting part 32 comprises a second fixed plate 321, a second guide block 322, a second moving seat 323 and a second adjusting member 324, the second fixed plate 321 is arranged in the first limiting groove 20a and is screwed with the first moving seat 313; both ends of the second fixed plate 321 in the second direction are provided with the second guide block 322, and a second guide groove is defined between the second guide block 322 and the second fixed plate 321, the second guide block 322 is provided with a plurality of third bolts 3221 which are arranged at intervals along the third direction, and the third bolts 3221 can lock the second moving seat 323 in the first direction; part of the second moving seat 323 is slidingly fitted in the second guide groove; both ends of the second fixed plate 321 in the third direction are provided with the second adjusting member 324, and the second adjusting member 324 can drive the second moving seat 323 to move along the third direction.

The second limiting groove 313a can limit the second fixed plate 321 along the second direction, or along the second direction and the third direction. The second fixed plate 321 can be nested with the first moving seat 313 through the second limiting groove 313a, so as to enhance the connection reliability of the second fixed plate 321 and the first moving seat 313.

[0071] The second guide block 322 can be L-shaped, and the length in the third direction is less than or equal to the length of the second fixed plate 321. The second adjusting member 324 can be, but is not limited to, a screw rod, a bolt, a jackscrew, a hydraulic cylinder, a pneumatic cylinder, an electric push rod, etc.

[0072] It can be understood that the second moving seat 323 has a certain gap with the second guide block 322 in the first direction, and the second adjusting member 324 can drive the second moving seat 323 to move in the third direction on the second guide groove, so as to realize fine adjustment of the lifting part 33 in the third direction. After the second adjusting member 324 is adjusted, the third bolt 3221 can be screwed to limit the second moving seat 323 in the third direction and the first direction, so that the second moving seat 323 is pressed on the second fixed plate 321, and the second adjusting part 32 is locked in the current position.

[0073] In the above technical solution, the second adjusting part 32 with the above structure can have high adjustment accuracy, can improve the adjustment reliability of the entire second adjusting part 32, and can lock the second adjusting part 32 after adjustment, so as to prevent loosening in the later period, and can improve the support reliability and stability of the support device 100 of the pre-assembly component 200 of the nuclear fusion device.

[0074] In some embodiments of the present application, with reference to Figure 9 The first fixed plate 311 is provided with a first positioning groove 311a extending in the second direction, the first guide block 312 is arranged in the first positioning groove 311a and is screwed with the first fixed plate 311; the first moving seat 313 is provided with a second positioning groove 313b, the second guide block 322 is arranged in the second positioning groove 313b and is screwed with the first moving seat 313. Optionally, the first positioning groove 311a and the second positioning groove 313b can be L-shaped grooves.

[0075] In the above technical solution, the first positioning groove 311a can limit the position of the first guide block 312 in the third direction upward, so that the first guide block 312 abuts against the groove wall of the first positioning groove 311a in the third direction, thereby making the first guide block 312 have high position accuracy and providing accurate guidance for the movement of the first moving seat 313. The second positioning groove 313b can limit the position of the second guide block 322 in the second direction, so that the second guide block 322 abuts against the groove wall of the second positioning groove 313b in the second direction, thereby making the second guide block 322 have high position accuracy and providing accurate guidance for the movement of the second moving seat 323.

[0076] In some embodiments of the present application, with reference to Figure 7 and Figure 9The sliding layer 301 is made of high-force brass surface inlaid with graphite technology.

[0077] In the above technical solution, the sliding layer 301 can reduce the sliding friction coefficient between the first fixed plate 311 and the first moving seat 313 and between the second fixed plate 321 and the second moving seat 323. Since the weights of the first adjusting part 31, the second adjusting part 32, and the lifting part 33 are relatively large, the sliding layer 301 facilitates the movement and adjustment of the first moving seat 313 and the second moving seat 323, and can reduce the operation difficulty. At the same time, the sliding layer 301 is made of high-force brass surface inlaid with graphite technology, has excellent load-bearing capacity and deformation resistance, and avoids damage to the support device 100 of the nuclear fusion device pre-assembly component.

[0078] In some embodiments of the present application, with reference to Figure 3 and Figure 4 The size of the second support section 20 is smaller than that of the first support section 10 and larger than that of the adjustable support section 30.

[0079] Since the support device 100 of the nuclear fusion device pre-assembly component has a large volume and weight, the first support section 10 and the second support section 20 are transported to the site separately, and the first support section 10 and the second support section 20 of the support device 100 of the nuclear fusion device pre-assembly component are installed on site. In the above technical solution, the size of the first support section 10 is the largest, which can be transported to the site by ground transportation equipment, for example, by a forklift. The sizes of the second support section 20 and the adjustable support section 30 are smaller, which can be transported to the site by hoisting, thereby reducing the hoisting load, reducing the requirements for hoisting equipment, and reducing the risk of safety accidents during hoisting. In the above technical solution, the second support section 20 and the adjustable support section 30 can be fixedly connected first, and then connected with the first support section 10 by hoisting, so that the size of the second support section 20 is larger than that of the adjustable support section 30, which further facilitates the installation of the support device 100 of the nuclear fusion device pre-assembly component and improves the installation efficiency of the support device 100 of the nuclear fusion device pre-assembly component.

[0080] In some embodiments of the present application, with reference to Figure 4 and Figure 11The first support section 10 comprises a leveling base 11, a first column 12, a first flange 13, a second flange 14 and a first reinforcing plate 15. The first column 12 is connected with the first flange 13 and the second flange 14 at two ends respectively. The first flange 13 is connected with the leveling base 11. The first reinforcing plate 15 is arranged around the circumference of the first column 12 and connected with the first flange 13 and the second flange 14. The second flange 14 is provided with a second positioning column 141, and the second positioning column 141 is provided with an anti-rotation surface 141a. The second support section 20 is screwed with the second flange 14 and provided with a positioning hole. The shape of the positioning hole matches that of the second positioning column 141, and the positioning hole can cooperate with the anti-rotation surface 141a to limit the rotation of the second support section 20 relative to the second flange 14 in the first direction.

[0081] The first flange 13 is similar in shape to the leveling base 11, which can be, but is not limited to, a circle, a polygon, an irregular figure and the like. Since the pre-embedded part on site can have problems such as uneven position or surface defects, the leveling base 11 can be processed into a shape that fits the pre-embedded part after on-site measurement, i.e., the leveling base 11 can realize on-site leveling, and then be connected with the first flange 13, thereby ensuring the perpendicularity of the entire first support section 10.

[0082] The first reinforcing plate 15 can be connected with the first column 12 in a manner such as, but not limited to, welding, bolt connection, riveting and the like, and the number thereof can be, but is not limited to, two, three, four, five and the like.

[0083] In the above technical solution, the leveling base 11 can level the support device 100 of the nuclear fusion device pre-assembly component, avoiding the influence of ground unevenness, inclination and the like on the support device 100 of the nuclear fusion device pre-assembly component, and improving the reliability of the support device 100 of the nuclear fusion device pre-assembly component. The second flange 14 is provided with the second positioning column 141, which can facilitate the installation of the first support section 10 and the second support section 20. The second positioning column 141 is provided with the anti-rotation surface 141a, which can prevent the relative rotation of the first support section 10 and the second support section 20, further improving the reliability of the support device 100 of the nuclear fusion device pre-assembly component.

[0084] The first reinforcing plate 15 is arranged around the circumference of the first column 12, so that the first reinforcing plate 15, the first column 12, the first flange 13 and the second flange 14 have high structural strength and rigidity. Since the pre-assembly component 200 has a large volume and weight, the above-mentioned solution can stably and reliably support the pre-assembly component 200 with the first support section 10, and also enables the first support section 10 to have small weight while meeting the structural strength, thereby facilitating transportation.

[0085] In some embodiments of the present application, reference is made to Figure 4 and Figure 10The second support section 20 comprises a third flange 21, a second column body 22, a fourth flange 23 and a second reinforcing plate 24. The third flange 21 is screwed with the second flange 14 and is provided with a positioning hole. The two ends of the second column body 22 are connected with the third flange 21 and the fourth flange 23 respectively. The third flange 21 and the fourth flange 23 are different in shape. The fourth flange 23 is connected with the adjustable support section 30. The second reinforcing plate 24 is provided with a plurality of second reinforcing plates 24 around the circumference of the second column body 22. The second reinforcing plate 24 connects the third flange 21 and the fourth flange 23. The second reinforcing plate 24 has a maximum width position and a minimum width position. The maximum width position is close to the fourth flange 23, and the minimum width position is close to the third flange 21.

[0086] The connection mode of the second reinforcing plate 24 and the second column body 22 can be, but is not limited to, welding, bolt connection, riveting and the like. The number can be, but is not limited to, two, three, four, five and the like.

[0087] The second reinforcing plate 24 has a maximum width position and a minimum width position. The maximum width position is close to the fourth flange 23, and the minimum width position is close to the third flange 21. It can be understood that in the direction from the third flange 21 to the fourth flange 23, the width of the second reinforcing plate 24 can gradually increase, or the width of the second reinforcing plate 24 can first gradually increase and then remain the same. Alternatively, the width of the second reinforcing plate 24 can first remain the same and then gradually increase. For example, referring to Figure 10 The width of the second reinforcing plate 24 first gradually increases and then remains the same.

[0088] Alternatively, the third flange 21 and the second flange 14 are the same in shape and size, which can be, but is not limited to, circular, polygonal and irregular shape and the like. This can facilitate the butt joint installation of the third flange 21 and the second flange 14 and improve the installation efficiency of the support device 100 of the pre-assembled component of the nuclear fusion device.

[0089] In the plane perpendicular to the first direction, the projection area of the second flange 14 is smaller than the projection area of the first flange 13, and the projection area of the third flange 21 is smaller than the projection area of the fourth flange 23. It can be understood that the second flange 14 and the first flange 13 are different in shape, which can prevent reverse rotation. The third flange 21 and the fourth flange 23 are different in shape or size. On the one hand, it can prevent reverse rotation. On the other hand, the fourth flange 23 has a larger support surface, which can better support the pre-assembled component 200.

[0090] In the above technical solution, the third flange 21 is screwed to the second flange 14, enabling quick disassembly and assembly, facilitating on-site assembly, and improving the installation efficiency of the support device 100 for the pre-assembled components of the nuclear fusion device. Simultaneously, the third flange 21 is provided with positioning holes, which facilitates the installation of the first support section 10 and the second support section 20, further improving the installation efficiency of the support device 100 for the pre-assembled components of the nuclear fusion device. The third flange 21 and the fourth flange 23 have different shapes, preventing the second support section 20 from being installed upside down. Multiple second reinforcing plates 24 are provided circumferentially around the second column 22, which can strengthen the structural strength of the support device 100 for the pre-assembled components of the nuclear fusion device, preventing damage due to excessive weight of the pre-assembled components 200, and also reducing the weight of the support device 100 for the pre-assembled components of the nuclear fusion device, facilitating its installation and transportation. Meanwhile, the second reinforcing plate 24 has a maximum width position and a minimum width position, which can further strengthen the structural strength of the support device 100 for the pre-assembled components of the nuclear fusion device and improve the reliability of the support device 100 for the pre-assembled components of the nuclear fusion device.

[0091] In some embodiments of the present invention, reference is made to Figure 4 , Figure 10 and Figure 11 The first support section 10 is provided with a first lifting lug 16, and the second support section 20 is provided with a second lifting lug 25.

[0092] In the above technical solution, the first support section 10 is provided with a first lifting lug 16, and the second support section 20 is provided with a second lifting lug 25, which can be used to lift the first support section 10 and the second support section 20. Since the support device 100 of the nuclear fusion device pre-assembly component is supported on the TF magnet at the bottom of the pre-assembly component 200, there is interference between the upper part of the support device 100 and the pre-assembly component 200. By providing at least three second lifting lugs 25 around the circumference of the second support section 20 in the first direction, the second support section 20 can be lifted at an angle. For example, three lifting tools can be used to lift from three directions together, or four lifting tools can be used to lift from four directions, etc. This can avoid interference between the second support section 20 and the adjustable support section 30 and the pre-assembly component 200 during the lifting process, and facilitate the on-site assembly of the support device 100 of the nuclear fusion device pre-assembly component.
