[0023] In the description of the present invention, unless otherwise specified, "plurality" means two or more. In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] The support device for a preassembled assembly of a nuclear fusion device according to an embodiment of the present invention can be applied to a nuclear fusion device. The nuclear fusion device may include a magnet, a vacuum chamber cold shield, and a vacuum chamber, which are fixedly connected to form a ring-shaped structure. The composition and operation of the nuclear fusion device are well known to those skilled in the art and are not described in detail here.

[0025] In a nuclear fusion device, such as a tokamak device, the magnet, vacuum chamber and vacuum chamber cold shield form a ring structure. During the construction process, a 1 / 8 sector of the ring structure is usually preassembled first, that is, 1 / 8 magnet, 1 / 8 vacuum chamber and 1 / 8 vacuum chamber cold shield are first assembled to form a preassembled component. Figure 1 and Figure 2 As shown, the supporting device 100 of the nuclear fusion device preassembled assembly according to the embodiment of the present invention is used to support the TF magnet at the bottom of the preassembled assembly 200 .

[0026] Reference below Figures 1-11 , describing a support device 100 for a preassembled assembly of a nuclear fusion device according to an embodiment of the present invention.

[0027] like Figure 3 and Figure 4 As shown, the support device 100 of the preassembled component of the nuclear fusion device according to the embodiment of the present invention includes a first support segment 10, a second support segment 20 and an adjustable support segment 30 which are detachably connected in sequence along a first direction; the adjustable support segment 30 includes a first adjustment portion 31, a second adjustment portion 32 and a lifting portion 33 which are connected in sequence along the first direction, the first adjustment portion 31 is connected to the second support segment 20, and can drive the second adjustment portion 32 to adjust along the second direction, the second adjustment portion 32 can drive the lifting portion 33 to adjust along the third direction, and the lifting portion 33 can be lifted and lowered along the first direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0028] The first support section 10 may refer to the foundation of the support device 100 of the entire nuclear fusion device pre-assembled assembly, and is relatively high and heavy, and is used to be fixed on the embedded parts of the host hall. The shape of the first support section 10 may be, but is not limited to, a cylinder, a rectangular parallelepiped, a polygonal prism, or other special-shaped structures. For example, referring to Figure 4 The first support section 10 is cylindrical in shape, has high torsional resistance and rigidity, and has a simple structure and is easy to process and manufacture.

[0029] The second support segment 20 is a component for connecting the first support segment 10 and the adjustable support segment 30, and has a similar shape to the first support segment 10. The second support segment 20 may be made of, but not limited to, alloy steel, stainless steel, aluminum alloy, composite material, and the like.

[0030] The adjustable support section 30 may refer to a component for adjusting the support position, which can realize positions in three directions: the first direction, the second direction, and the third direction. The connection method of the adjustable support section 30 and the second support section 20 may be, but is not limited to, clamping, bolting, riveting, etc. In the above technical solution, the adjustable support section 30 includes a first adjustment part 31, a second adjustment part 32, and a lifting part 33 connected in sequence along the first direction. The first adjustment part 31 may refer to a component that is connected to the second support section 20 and has an adjustment stroke along the second direction. The second adjustment part 32 may refer to a component that has an adjustment stroke along the third direction. The lifting part 33 may refer to a component that has an adjustment stroke along the first direction. The first adjustment part 31, the second adjustment part 32, and the lifting part 33 may be electric adjustment mechanisms or manual adjustment mechanisms. Among them, reference Figure 3 As an example, the “first direction” may refer to the up-down direction, the “second direction” may refer to the front-back direction, and the “third direction” may refer to the left-right direction.

[0031] It is understandable that due to the large size and weight of the support device 100 for the pre-assembled components of the nuclear fusion device, and the large number of components and limited space in the main hall of the nuclear fusion device, hoisting the complete support device 100 for the pre-assembled components of the nuclear fusion device into the main hall is difficult and inconvenient. Because the first support segment 10 and the second support segment 20 are detachable, they can be transported separately to the site, where the first support segment 10 and the second support segment 20 can be installed. For example, the first support segment 10 can typically be nearly two meters high and weigh nearly two tons. It can be transported using a forklift or other components and secured to the embedded parts in the main hall. The second support segment 20 and the adjustable support segment 30 can be fixedly connected before being hoisted into place. The second support segment 20 and the adjustable support segment 30 can then be hoisted and attached to the second support segment 20 using slings and shackles. They are then slowly moved laterally to ensure that they do not collide with the vacuum chamber cold shield. After the first support segment 10 is in place, they are adjusted and secured.

[0032] When it is necessary to support the pre-installed component 200, since the first support section 10 is first fixed on the embedded parts of the main machine hall, the first support section 10 and the TF magnet at the bottom of the pre-installed component 200 do not need to maintain a high position accuracy. This facilitates the rapid installation and fixation of the first support section 10 on site, and then the support position is precisely adjusted through the adjustable support section 30. Specifically, the first adjustment part 31 can be fine-tuned along the radial direction (i.e., the second direction) of the pre-installed component 200, the second adjustment part 32 can be fine-tuned along the circumferential direction (i.e., the third direction) of the pre-installed component 200, and the lifting part 33 can be fine-tuned along the height direction (i.e., the first direction) of the pre-installed component 200, thereby enabling the lifting part 33 to support the target position of the TF magnet at the bottom of the pre-installed component 200, stably and reliably supporting the pre-installed component 200, ensuring the position accuracy of the pre-installed component 200 in the subsequent assembly process, and preventing the pre-installed component 200 from displacement.

[0033] According to the support device 100 for the preassembled assembly of a nuclear fusion device according to an embodiment of the present invention, by configuring the support device 100 for the preassembled assembly of a nuclear fusion device to include a detachable first support section 10, a second support section 20, and an adjustable support section 30, it is convenient to transport the large-sized and heavy support device 100 for the preassembled assembly of a nuclear fusion device to the host hall, and facilitate the on-site arrangement of the support device 100 for the preassembled assembly of a nuclear fusion device. By configuring the adjustable support section 30 to include a first adjustment portion 31, a second adjustment portion 32, and a lifting portion 33, the adjustable support section 30 can achieve three-degree-of-freedom adjustment, can be aligned with the TF magnet at the bottom of the preassembled assembly 200, better support the preassembled assembly 200, help improve the positional accuracy of the preassembled assembly 200, and further improve the reliability of the installation of the nuclear fusion device.

[0034] In some embodiments of the present invention, reference Figure 5The lifting part 33 includes a lifting part body 331, a support seat 332 and a limit member 333. The lifting part body 331 is arranged on the second adjusting part 32; the support seat 332 is connected to the lifting end 3311 of the lifting part body 331 and is provided with a first positioning column 33201; the limit member 333 is arranged on the second adjusting part 32 and cooperates with the support seat 332 to limit the support seat 332 from rotating around the first direction.

[0035] The lifting unit body 331 can be a component that can be extended and retracted in 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 screw, etc. The limiting member 333 can be a component used to limit the rotation of the support base 332 in the first direction, and can be, but is not limited to, a limiting pin, a limiting block, a housing, etc. The first positioning column 33201 can be, but is not limited to, a positioning round pin, a prism, etc.

[0036] In the above technical solution, the first positioning post 33201 can cooperate with the hole in the TF magnet, so that the pre-assembled component 200 and the lifting unit 33 are connected together to better support the pre-assembled component 200. The support base 332 can prevent the lifting unit 33 from contacting the TF magnet, and the limiter 333 can limit the rotation of the support base 332 about the first direction. This can reduce the risk of the lifting unit body 331 causing the pre-assembled component 200 to rotate slightly about the first direction during the process of lifting the pre-assembled component 200, thereby improving the position reliability of the pre-assembled component 200.

[0037] In some embodiments of the present invention, reference Figures 5 to 7 A limiting space 333a is provided inside the limiting member 333, and the limiting space 333a is open at one end away from the second adjusting portion 32; 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, and the sliding shell 3322 is open on one side close to the second adjusting portion 32, and the circumference of the sliding shell 3322 is fitted with the circumference of the limiting space 333a, and the shell wall of the sliding shell 3322 and the limiting space 333a at least partially forms a straight wall.

[0038] The limiting member 333 may be a shell-like structure, or a structure composed of multiple components and enclosing a limiting space 333a. Figure 5 The limiting member 333 can be assembled from a plurality of I-beams, and the plurality of I-beams together define a limiting space 333a.

[0039] In the above technical solution, the circumference of the sliding shell 3322 and the circumference of the limiting space 333a are fitted together, which has a guiding effect. Since the pre-assembled component 200 is large in volume and heavy in weight, this solution 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 reliability.

[0040] The walls of the sliding shell 3322 that cooperate with the limiting space 333a at least partially form a straight wall. That is, the limiting space 333a and the sliding shell 3322 have at least one straight wall around their periphery, which can form a surface contact constraint to achieve cooperation between the limiting member 333 and the sliding shell 3322, thereby limiting the rotation of the support plate 3321 about the first direction. Compared with traditional keyway or pin structures, the above-mentioned solution has a larger contact area and stronger torsion resistance, which is more effective in preventing the support seat 332 from rotating about the first direction, and can better improve the reliability of the support device 100 for the pre-assembled components of the nuclear fusion device. The circumferential shape of the sliding shell 3322 and the limiting space 333a about the first direction can be rectangular, triangular, fan-shaped, semicircular, etc.

[0041] In some embodiments of the present invention, reference Figures 6 to 8 The limiting member 333 is provided with a strip hole 333b extending along the first direction, the sliding shell 3322 is provided with a first threaded hole 3322a, and the lifting portion 33 further includes a first bolt 334, which is passed through the strip hole 333b and screwed with the first threaded hole 3322a.

[0042] There may be multiple strip-shaped holes 333b, which may be, but not limited to, two, three, four, five, etc.

[0043] In the above technical solution, the strip-shaped hole 333b extends along the first direction, providing guidance in the first direction. Since the support base 332 itself is relatively heavy and large in size, the cooperation between the strip-shaped hole 333b and the first bolt 334 facilitates the installation of the sliding shell 3322 and the stopper 333. Secondly, after the lifting portion body 331 is lifted into position, the first bolt 334 can be tightened against the outside of the stopper 333, locking the sliding shell 3322 and the stopper 333. This reduces the risk of the lifting portion body 331 resetting in the first direction and further improves the reliability of the support device 100 for the pre-assembled assembly 200.

[0044] In some embodiments of the present invention, reference Figure 5 、 Figure 9 and Figure 10The second supporting section 20 is provided with a first limiting groove 20a; the first adjusting portion 31 includes a first fixing plate 311, a first guide block 312, a first movable seat 313 and a first adjusting member 314. The first fixing plate 311 is provided in the first limiting groove 20a and is screwed to the second supporting section 20; both ends of the first fixing plate 311 in the third direction are provided with a first guide block 312, and a first guide groove 31a is defined between the first guide block 312 and the first fixing plate 311. The first guide block 312 is provided with a plurality of second bolts 3121 arranged at intervals along the second direction, and the second bolts 3121 can lock the first movable seat 313 in the first direction; a part of the first movable seat 313 is slidably fitted in the first guide groove 31a; both ends of the first fixing plate 311 in the second direction are provided with a first adjusting member 314, and the first adjusting member 314 can drive the first movable seat 313 to move along the second direction.

[0045] The first limiting groove 20a can limit the first fixing plate 311, preventing it from moving relative to the second support segment 20. The first limiting groove 20a can limit the first fixing plate 311 in the third direction, or in both the third and second directions. The first limiting groove 20a allows the first fixing plate 311 to nest with the second support segment 20, enhancing the connection reliability between the first fixing plate 311 and the second support segment 20.

[0046] The first guide block 312 may be L-shaped, and its length in the second direction may be less than or equal to the length of the first fixing plate 311. The first adjusting member 314 may be, but is not limited to, a screw, a bolt, a jackscrew, a hydraulic cylinder, an air cylinder, an electric push rod, and the like.

[0047] It is understood that there is a certain gap between the first movable seat 313 and the first guide block 312 in the first direction. The first adjusting member 314 can be used to drive the first movable seat 313 to move in the second direction on the first guide groove 31a, thereby achieving fine adjustment of the second adjustment portion 32 and the lifting portion 33 in the second direction. After the first adjusting member 314 is adjusted, the second bolt 3121 is tightened to limit the first movable seat 313 in the second and first directions, pressing the first movable seat 313 against the first fixing plate 311, thereby locking the first adjustment portion 31 in its current position.

[0048] In the above technical solution, the first adjustment part 31 adopting the above structure can have higher adjustment accuracy and improve the adjustment reliability of the entire first adjustment part 31. Moreover, the first adjustment part 31 can be locked after the adjustment is completed to prevent loosening in the later stage, thereby improving the support reliability and stability of the support device 100 of the pre-assembled component of the nuclear fusion device to the pre-assembled component 200.

[0049] In some embodiments of the present invention, reference Figure 5 、 Figure 7 and Figure 9 The first movable seat 313 is provided with a second limiting slot 313a; the second adjusting portion 32 includes a second fixing plate 321, a second guide block 322, a second movable seat 323 and a second adjusting member 324. The second fixing plate 321 is arranged in the first limiting slot 20a and is screwed to the first movable seat 313; both ends of the second fixing plate 321 in the second direction are provided with a second guide block 322, and a second guide slot is defined between the second guide block 322 and the second fixing plate 321. The second guide block 322 is provided with a plurality of third bolts 3221 arranged at intervals along the third direction, and the third bolt 3221 can lock the second movable seat 323 in the first direction; part of the second movable seat 323 is slidably fitted in the second guide slot; both ends of the second fixing plate 321 in the third direction are provided with a second adjusting member 324, and the second adjusting member 324 can drive the second movable seat 323 to move along the third direction.

[0050] The second limiting groove 313a can limit the second fixed plate 321, preventing it from moving relative to the first movable base 313. The second limiting groove 313a can limit the second fixed plate 321 along the second direction, or along both the second and third directions. The second limiting groove 313a allows the second fixed plate 321 to nest with the first movable base 313, enhancing the connection reliability between the second fixed plate 321 and the first movable base 313.

[0051] The second guide block 322 may be L-shaped, and its length in the third direction may be less than or equal to the length of the second fixing plate 321. The second adjusting member 324 may be, but is not limited to, a screw, a bolt, a jackscrew, a hydraulic cylinder, an air cylinder, an electric push rod, and the like.

[0052] It is understood that there is a certain gap between the second movable seat 323 and the second guide block 322 in the first direction. The second adjusting member 324 can be used to drive the second movable seat 323 to move along the second guide groove in the third direction, thereby achieving fine adjustment of the lifting portion 33 in the third direction. After the second adjusting member 324 is adjusted, the second movable seat 323 can be limited in the third and first directions by tightening the third bolt 3221, so that the second movable seat 323 is pressed against the second fixing plate 321, and the second adjusting portion 32 is locked in its current position.

[0053] In the above technical solution, the second adjustment part 32 adopting the above structure can have higher adjustment accuracy and improve the adjustment reliability of the entire second adjustment part 32. Moreover, the second adjustment part 32 can be locked after the adjustment is completed to prevent loosening in the later stage, thereby improving the support reliability and stability of the support device 100 of the pre-assembled component of the nuclear fusion device to the pre-assembled component 200.

[0054] In some embodiments of the present invention, reference Figure 9 The first fixed plate 311 is provided with a first positioning groove 311a extending along the second direction. The first guide block 312 is disposed in the first positioning groove 311a and is screwed to the first fixed plate 311. The first movable base 313 is provided with a second positioning groove 313b. The second guide block 322 is disposed in the second positioning groove 313b and is screwed to the first movable base 313. Optionally, the first positioning groove 311a and the second positioning groove 313b may be L-shaped grooves.

[0055] In the above technical solution, the first positioning groove 311a can limit the upward position of the first guide block 312 in the third direction, causing the first guide block 312 to abut against the groove wall of the first positioning groove 311a in the third direction, thereby ensuring that the first guide block 312 has a high positional accuracy and provides precise guidance for the movement of the first movable seat 313. The second positioning groove 313b can limit the position of the second guide block 322 in the second direction, causing the second guide block 322 to abut against the groove wall of the second positioning groove 313b in the second direction, thereby ensuring that the second guide block 322 has a high positional accuracy and provides precise guidance for the movement of the second movable seat 323.

[0056] In some embodiments of the present invention, reference Figure 7 and Figure 9 A sliding layer 301 is provided between the first fixed plate 311 and the first movable seat 313, and between the second fixed plate 321 and the second movable seat 323. The sliding layer 301 is made of high-strength brass surface inlaid with graphite process.

[0057] In the above technical solution, sliding layer 301 can reduce the sliding friction coefficient between the first fixed plate 311 and the first movable seat 313, as well as between the second fixed plate 321 and the second movable seat 323. Since the first adjustment portion 31, the second adjustment portion 32, and the lifting portion 33 are all relatively heavy, the provision of sliding layer 301 facilitates the movement and adjustment of the first and second movable seats 313, 323, thus reducing operational difficulty. Furthermore, sliding layer 301 is manufactured from high-strength brass with a graphite inlay process, providing excellent load-bearing capacity and deformation resistance, thereby preventing damage to the support device 100 of the nuclear fusion device pre-assembled assembly.

[0058] In some embodiments of the present invention, reference Figure 3 and Figure 4 The size of the second support segment 20 is smaller than that of the first support segment 10 and larger than that of the adjustable support segment 30.

[0059] Since the support device 100 of the pre-assembled assembly of the nuclear fusion device is relatively large in size and weight, the first support segment 10 and the second support segment 20 are transported to the site separately, and the first support segment 10 and the second support segment 20 of the support device 100 of the pre-assembled assembly of the nuclear fusion device are installed on site. In the above technical solution, the first support segment 10 is the largest in size and can be transported to the site by ground transportation equipment, for example, by a forklift. The second support segment 20 and the adjustable support segment 30 are smaller in size and can be transported to the site by hoisting, which can reduce the hoisting load, reduce the requirements for hoisting equipment, and also reduce the risk of safety accidents during the hoisting process. In the above technical solution, the second support segment 20 and the adjustable support segment 30 can also be fixedly connected first and then connected to the first support segment 10 by hoisting. Therefore, the second support segment 20 is larger than the adjustable support segment 30, which further facilitates the installation of the support device 100 of the pre-assembled assembly of the nuclear fusion device and improves the installation efficiency of the support device 100 of the pre-assembled assembly of the nuclear fusion device.

[0060] In some embodiments of the present invention, reference Figure 4 and Figure 11 The first support section 10 includes a leveling base 11, a first column 12, a first flange 13, a second flange 14 and a first reinforcing plate 15. The two ends of the first column 12 are respectively connected to the first flange 13 and the second flange 14. The first flange 13 is connected to the leveling base 11. Multiple first reinforcing plates 15 are provided around the circumference of the first column 12, and the first reinforcing plates 15 connect the first flange 13 and the second flange 14; wherein, 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 to the second flange 14 and is provided with a positioning hole. The positioning hole matches the shape of the second positioning column 141 and can cooperate with the anti-rotation surface 141a to limit the second support section 20 from rotating relative to the second flange 14 about the first direction.

[0061] The first flange 13 has a similar shape to the leveling base 11 and can be, but is not limited to, circular, polygonal, or irregular. Because embedded components may be uneven or have surface defects, the leveling base 11 can be machined to match the embedded components after on-site measurement. In other words, the leveling base 11 can be leveled on-site and then connected to the first flange 13, thereby ensuring the verticality of the entire first support section 10.

[0062] The first reinforcing plate 15 and the first column 12 may be connected to each other by, but not limited to, welding, bolt connection, riveting, etc., and the number may be, but not limited to, two, three, four, five, etc.

[0063] In the above technical solution, the leveling base 11 can level the support device 100 for the preassembled assembly of the nuclear fusion device, preventing the support device 100 from being affected by unevenness or tilt of the ground, thereby improving the reliability of the support device 100 for the preassembled assembly of the nuclear fusion device. The second flange 14 is provided with a second positioning column 141 to facilitate the installation of the first support segment 10 and the second support segment 20. The second positioning column 141 is provided with an anti-rotation surface 141a to prevent the first support segment 10 and the second support segment 20 from rotating relative to each other, further improving the reliability of the support device 100 for the preassembled assembly of the nuclear fusion device.

[0064] Multiple first reinforcing plates 15 are provided around the circumference of the first column 12, so that the whole formed by the first reinforcing plates 15, the first column 12, the first flange 13, and the second flange 14 has high structural strength and rigidity. Since the pre-assembled component 200 is large in volume and weight, the above-mentioned solution enables the first support section 10 to stably and reliably support the pre-assembled component 200, and also enables the first support section 10 to have a smaller weight while meeting the structural strength requirements, which is convenient for transportation.

[0065] In some embodiments of the present invention, reference Figure 4 and Figure 10 The second support section 20 includes a third flange 21, a second column 22, a fourth flange 23 and a second reinforcing plate 24. The third flange 21 is screwed to the second flange 14 and is provided with a positioning hole. The two ends of the second column 22 are respectively connected to the third flange 21 and the fourth flange 23. The shapes of the third flange 21 and the fourth flange 23 are different. The fourth flange 23 is connected to the adjustable support section 30; multiple second reinforcing plates 24 are provided around the circumference of the second column 22, and the second reinforcing plates 24 connect the third flange 21 and the fourth flange 23; wherein 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.

[0066] The second reinforcing plate 24 and the second column 22 may be connected by, but not limited to, welding, bolt connection, riveting, etc., and the number may be, but not limited to, two, three, four, five, etc.

[0067] 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; or the width of the second reinforcing plate 24 can also first remain the same and then gradually increase. For example, referring to Figure 10 , the width of the second reinforcing plate 24 gradually increases and then remains the same.

[0068] Optionally, the third flange 21 and the second flange 14 have the same shape and size, which can be but not limited to circular, polygonal, irregular shapes, etc., which can facilitate the docking 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 components of the nuclear fusion device.

[0069] On a plane perpendicular to the first direction, the projected area of ​​the second flange 14 is smaller than that of the first flange 13, and the projected area of ​​the third flange 21 is smaller than that of the fourth flange 23. It will be appreciated that the different shapes of the second flange 14 and the first flange 13 prevent inversion. The different shapes or sizes of the third flange 21 and the fourth flange 23 not only prevent inversion, but also provide a larger support surface for the fourth flange 23, better supporting the pre-assembled component 200.

[0070] In the above technical solution, the third flange 21 is screwed to the second flange 14, which can achieve rapid disassembly and assembly, facilitate on-site assembly, and improve the installation efficiency of the support device 100 of the pre-assembled component of the nuclear fusion device. At the same time, the third flange 21 is provided with a positioning hole, which can facilitate the installation of the first support section 10 and the second support section 20, further improving the installation efficiency of the support device 100 of the pre-assembled component of the nuclear fusion device. The third flange 21 and the fourth flange 23 have different shapes, which can prevent the second support section 20 from being inverted. A plurality of second reinforcing plates 24 are provided around the circumference of the second column 22, which can strengthen the structural strength of the support device 100 of the pre-assembled component of the nuclear fusion device, avoid damage due to the excessive weight of the pre-assembled component 200, and reduce the weight of the support device 100 of the pre-assembled component of the nuclear fusion device, thereby facilitating the installation and transportation of the support device 100 of the pre-assembled component of the nuclear fusion device. At the same time, 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 of the nuclear fusion device preassembled assembly and improve the reliability of the support device 100 of the nuclear fusion device preassembled assembly.

[0071] In some embodiments of the present invention, reference Figure 4 、 Figure 10 and Figure 11 The first support segment 10 is provided with a first lifting lug 16, and the second support segment 20 is provided with a second lifting lug 25. At least three second lifting lugs 25 are provided around the circumference of the second support segment 20 in the first direction. The number of second lifting lugs 25 can be, but is not limited to, three, four, five, six, etc.

[0072] In the above technical solution, the first support segment 10 is provided with a first lifting lug 16, and the second support segment 20 is provided with a second lifting lug 25, which can be used to lift the first support segment 10 and the second support segment 20. Since the support device 100 of the nuclear fusion device preassembled assembly is supported on the TF magnet at the bottom of the preassembled assembly 200, the upper part of the support device 100 of the nuclear fusion device preassembled assembly interferes with the preassembled assembly 200. At least three second lifting lugs 25 are provided around the circumference of the second support segment 20 in the first direction. This allows the second support segment 20 to be lifted at an angle, for example, using three lifting devices to lift it from three directions, or using four lifting devices to lift it from four directions, etc. This can prevent the second support segment 20 and the adjustable support segment 30 from interfering with the preassembled assembly 200 during the lifting process, thereby facilitating on-site assembly of the support device 100 of the nuclear fusion device preassembled assembly.
