Description

Technical Field

[0001] This invention relates to the field of nuclear fusion technology, and in particular to an assembly method and assembly tooling for a toroidal field superconducting magnet for a nuclear fusion device. Background Technology

[0002] Nuclear fusion, as a new type of efficient and clean energy source, is widely regarded as the ultimate solution to humanity's energy problem. Therefore, controlled nuclear fusion is an important field that countries around the world are actively researching and exploring. Controlled nuclear fusion uses a fusion device called a tokamak to magnetically confine high-temperature plasma, causing the plasma to undergo a fusion reaction in a vacuum chamber, releasing enormous energy, which is then converted and ultimately used by humanity.

[0003] The main unit of the tokamak device consists of eight main unit sectors. Each main unit sector component includes components such as a vacuum chamber sector, a vacuum chamber cold screen sector, and a toroidal field magnet. During the assembly of the main unit sectors, the toroidal field magnet moves along a circular track and is fitted onto the outside of the vacuum chamber and cold screen sectors. Because the assembly gap between the toroidal field magnet and the vacuum chamber cold screen sector is small, the toroidal field magnet needs to be adjusted in position and orientation multiple times during the assembly process to avoid collision interference.

[0004] In existing technologies, the position adjustment of three translational degrees of freedom can be achieved when adjusting a toroidal field superconducting magnet, but the three rotational degrees of freedom of the magnet cannot be adjusted. For ultra-large toroidal field superconducting magnets in nuclear fusion devices, the assembly position accuracy of each point has extremely high technical requirements. Therefore, the position adjustment of only three translational degrees of freedom cannot fully meet the assembly requirements of the magnet. The magnet assembly accuracy is poor and the efficiency is low. There is a risk that the superconducting magnet cannot be assembled or that there is collision interference, which cannot meet the assembly requirements of the fusion reactor main unit sector. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an assembly fixture that can effectively adjust the rotation angle of a circumferential field superconducting magnet around a first axis, a second axis, and / or a third axis, thereby effectively meeting assembly requirements and improving installation effect and assembly efficiency.

[0051] 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.

[0052] The following is for reference. Figures 1-7 An assembly fixture 100 according to an embodiment of the first aspect of the present invention is described.

[0053] like Figure 1 and Figure 2 As shown, according to an embodiment of the first aspect of the present invention, the assembly fixture 100 is used to install the toroidal field superconducting magnet 200 of a nuclear fusion device. The assembly fixture 100 includes: a support frame 1, a support bracket 2, and a driving device.

[0054] Support frame 2 is mounted on support frame 1. Support frame 2 is used to support the circumferential field superconducting magnet 200. Support frame 2 is positioned relative to support frame 1 along a first direction (e.g., Figure 1 The first axis extending in the vertical direction, and along the second direction (e.g.) Figure 1The second axis extends in the left-right direction and / or along a third direction (e.g., in the left-right direction) and / or along a third direction (e.g.) Figure 1 The third axis extending in the front-back direction is rotatable, and the first, second and third directions are perpendicular to each other; the drive device is connected to the support frame 1 and is used to drive the support frame 2 to rotate relative to the support frame 1 around the first axis, the second axis and / or the third axis.

[0055] Where the first direction, the second direction, and the third direction are all perpendicular to each other, it means that the angle between any two of the first direction, the second direction, and the third direction is 90°. In a specific example, such as... Figure 1 and Figure 2 As shown, the first direction is up and down, the second direction is left and right, and the third direction is front and back. The first, second, and third directions are perpendicular to each other. For example... Figure 2 As shown, the lower end of the circumferential field superconducting magnet 200 is fixed on the support frame 2, thereby enabling the circumferential field superconducting magnet 200 to rotate together with the support frame 2.

[0056] In a specific example, such as Figure 1 and Figure 2 As shown, the support frame 1 includes a support platform 11, a back frame 12, and a first adjustment mechanism 13. Specifically, the support platform 11 is located at the bottom of the support frame 1, and its rear side is connected to the bottom of the back frame 12. Multiple pairs of pulley assemblies are connected to the bottom of the support platform 11, and these pulley assemblies can correspond one-to-one with multiple annular tracks to adjust the position of the toroidal field superconducting magnet 200 in the horizontal plane. The first adjustment mechanism 13 is located between the support platform 11 and the support frame 2. The first adjustment mechanism 13 can move upwards or downwards, thereby driving the support frame 2 and the toroidal field superconducting magnet 200 to move upwards or downwards. Furthermore, both the support frame 1 and the support frame 2 can be welded from steel plates, thereby improving structural strength and load-bearing capacity.

[0057] For example Figure 1 and Figure 2 As shown, a driving device is provided on the back frame 12, which can drive the support frame 2 to rotate relative to the support frame 1. For example, the driving device can drive the support frame 2 to rotate relative to the support frame 1 about any one of the first axis, the second axis, and the third axis; or, the driving device can drive the support frame 2 to rotate relative to the support frame 1 about any two of the first axis, the second axis, and the third axis; or, the driving device can drive the support frame 2 to rotate relative to the support frame 1 about the first axis, the second axis, and the third axis.

[0058] In this embodiment, when adjusting the angle of the toroidal superconducting magnet 200, the lower end of the toroidal superconducting magnet 200 is first fixedly mounted on the support frame 2. Then, the driving device is fixedly connected to the toroidal superconducting magnet 200. After that, the driving device enables the support frame 2 and the toroidal superconducting magnet 200 fixedly mounted on the support frame 2 to rotate relative to the support frame 1 around a first axis extending in the vertical direction, a second axis extending in the horizontal direction, and / or a third axis extending in the front-back direction. This effectively adjusts the rotation angle of the toroidal superconducting magnet 200, thereby effectively adjusting the attitude of the toroidal superconducting magnet 200 and avoiding collision interference between the toroidal superconducting magnet 200 and the cold screen sector of the vacuum chamber. This effectively ensures the installation effect and improves the assembly efficiency.

[0059] According to an embodiment of the present invention, the assembly fixture 100 includes a support frame 1, a support bracket 2, and a driving device. The support bracket 2 is mounted on the support frame 1 and is used to support the circumferential superconducting magnet 200. The support bracket 2 is rotatable relative to the support frame 1 around a first axis extending in a first direction, a second axis extending in a second direction, and / or a third axis extending in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The driving device is connected to the support frame 1 and is used to drive the support bracket 2 to rotate relative to the support frame 1 around the first axis, the second axis, and / or the third axis. This allows for effective adjustment of the rotation angle of the circumferential superconducting magnet 200 around the first axis, the second axis, and / or the third axis when installing the circumferential superconducting magnet 200 of the nuclear fusion device, thereby meeting the assembly requirements of the circumferential superconducting magnet 200 and effectively improving the installation effect and assembly efficiency.

[0060] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the support frame 2 is rotatably connected to the support frame 1 via a first ball joint. The assembly fixture 100 also includes a connecting frame 4, which is adapted to be fixedly connected to the circumferential field superconducting magnet 200. The connecting frame 4 and the support frame 2 are adapted to be arranged on opposite sides of the circumferential field superconducting magnet 200 in a first direction. The connecting frame 4 is rotatably connected to the support frame 1 via a second ball joint 5. The first axis is a straight line passing through the center of the first ball joint and the center of the second ball joint 5. The driving device includes a first driving assembly 31, which is used to drive the circumferential field superconducting magnet 200 to rotate around the first axis.

[0061] In a specific example, such as Figure 1 and Figure 2 As shown, the first ball joint is disposed between the support frame 2 and the first adjusting mechanism 13. Furthermore, the first ball joint can be a spherical sliding bearing. For example... Figure 1 and Figure 2As shown, the connector is located on the upper side of the toroidal superconducting magnet 200, and the support frame 2 is located on the lower side of the toroidal superconducting magnet 200. Furthermore, the connector 4 and the support frame 2 are fixedly connected to the upper and lower sides of the toroidal superconducting magnet 200, respectively. When the first drive assembly 31 operates, it can drive the support frame 2, the toroidal superconducting magnet 200, and the connector 4 to rotate around the first axis, thereby adjusting the rotation angle of the toroidal superconducting magnet 200 around the first axis.

[0062] In this embodiment, the support frame 2 is rotatably connected to the support frame 1 via a first ball joint. The assembly fixture 100 also includes a connecting frame 4, which is adapted to be fixedly connected to the toroidal field superconducting magnet 200. The connecting frame 4 and the support frame 2 are adapted to be arranged on opposite sides of the toroidal field superconducting magnet 200 in a first direction. The connecting frame 4 is rotatably connected to the support frame 1 via a second ball joint 5. The first axis is a straight line passing through the center of the first ball joint and the center of the second ball joint 5, so that the toroidal field superconducting magnet 200 can rotate around the first axis, thereby effectively adjusting the rotation angle of the toroidal field superconducting magnet 200 around the first axis. By setting a first driving component 31 in the driving device, the first driving component 31 is used to drive the toroidal field superconducting magnet 200 to rotate around the first axis, which can effectively improve the efficiency of rotating the toroidal field superconducting magnet 200.

[0063] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, there are multiple first driving components 31, which are adapted to be arranged on opposite sides of the circumferential field superconducting magnet 200 in the second direction. One end of the first driving component 31 is fixed to the support frame 1 and the other end is adapted to be fixedly connected to the circumferential field superconducting magnet 200.

[0064] For example, the number of first driving components 31 can be two, three, four, five, or more than six, with multiple first driving components 31 arranged on the left and right sides of the circumferential field superconducting magnet 200, respectively. In a specific example, such as Figure 1 and Figure 2 As shown, there are three first driving components 31. One first driving component 31 is located on the left side of the circumferential field superconducting magnet 200, and the other two first driving components 31 are located on the right side of the circumferential field superconducting magnet 200 and are arranged vertically at intervals.

[0065] In this embodiment, by setting the number of first driving components 31 to multiple, the multiple first driving components 31 are adapted to be respectively arranged on opposite sides of the circumferential field superconducting magnet 200 in the second direction. One end of the first driving component 31 is fixed to the support frame 1 and the other end is adapted to be fixedly connected to the circumferential field superconducting magnet 200. This ensures that the driving force is evenly distributed on the circumferential field superconducting magnet 200, thereby helping to reduce stress concentration caused by single-point force and thus effectively improving the safety of the overall structure. In addition, it can also provide additional support for the circumferential field superconducting magnet 200, thereby helping to maintain the stability of the circumferential field superconducting magnet 200 during the adjustment process and reducing unnecessary vibration or shaking.

[0066] In one embodiment of the present invention, such as Figure 3 As shown, the first drive assembly 31 includes: a first fixed bracket 311, a first connecting bracket 312, and a first drive member 313.

[0067] The first fixed bracket 311 is fixed to the support frame 1; the first connecting bracket 312 is adapted to be fixedly connected to the circumferential field superconducting magnet 200; the first driving member 313 has a first fixed end and a first movable end that is movable relative to the first fixed end along a third direction, the first fixed end is connected to the first fixed bracket 311 by a ball joint, and the first movable end is connected to the first connecting bracket 312 by a ball joint.

[0068] In a specific example, such as Figure 3 As shown, the first fixed bracket 311 is bolted to the back frame 12, and the first connecting bracket 312 is welded to the circumferential field superconducting magnet 200. The first movable end of the first driving member 313 can move forward or backward relative to the first fixed end. The first fixed end is connected to the first fixed bracket 311 via a ball joint, thereby allowing the first driving member 313 to rotate in any direction relative to the first fixed bracket 311. The first movable end is connected to the first connecting bracket 312 via a ball joint, thereby allowing the first driving member 313 to rotate in any direction relative to the first connecting bracket 312.

[0069] Furthermore, the first driving component 313 can be a double-acting hydraulic cylinder. A double-acting hydraulic cylinder utilizes fluid pressure to extend and retract the piston rod. It not only provides powerful pushing and pulling forces but also precisely controls the piston rod's movement distance, thereby effectively improving adjustment accuracy. Specifically, a displacement sensor is installed between the cylinder body and the piston rod of the double-acting hydraulic cylinder to measure and control the precise extension and retraction of the hydraulic rod. The double-acting hydraulic cylinder uses a servo hydraulic control system, achieving a motion accuracy of ±0.5mm. In addition, the first driving component 313 can also be a linear servo motor or a combination of a rotary servo motor and a linear motion mechanism.

[0070] When the first movable end of the first driving member 313 located on the left side of the circumferential field superconducting magnet 200 moves backward and the first movable end of the first driving member 313 located on the right side of the circumferential field superconducting magnet 200 moves forward, the circumferential field superconducting magnet 200 can rotate in one direction around the first axis; when the first movable end of the first driving member 313 located on the left side of the circumferential field superconducting magnet 200 moves forward and the first movable end of the first driving member 313 located on the right side of the circumferential field superconducting magnet 200 moves backward, the circumferential field superconducting magnet 200 can rotate in another direction around the first axis.

[0071] This embodiment incorporates a fixed bracket, a first connecting bracket 312, and a first driving member 313 within the first driving assembly 31. The first fixed bracket 311 is fixed to the support frame 1, and the first connecting bracket 312 is adapted to be fixedly connected to the circumferential field superconducting magnet 200. The first driving member 313 has a first fixed end and a first movable end that is movable relative to the first fixed end along a third direction. The first fixed end is connected to the first fixed bracket 311 via a ball joint, and the first movable end is connected to the first connecting bracket 312 via a ball joint. This allows the first driving member 313 to rotate relative to the first connecting bracket 312 in any direction, thereby effectively improving the rotational flexibility of the circumferential field superconducting magnet 200. Furthermore, it effectively simplifies the structural design of the first driving assembly 31, thereby improving the ease of maintenance of the first driving assembly 31.

[0072] In one embodiment of the present invention, such as Figure 3 As shown, the assembly fixture 100 also includes: a first moving platform 6 and a connecting plate 7. The first moving platform 6 is movably mounted on the support frame 1 along the second direction; the first moving platform 6 is connected to the connecting frame 4 through the connecting plate 7, and the second ball joint 5 is connected between the connecting frame 4 and the connecting plate 7; the driving device includes a second driving assembly 32, which is mounted on the support frame 1 and connected to the first moving platform 6 for driving the first moving platform 6 to move along the second direction, so as to drive the circumferential field superconducting magnet 200 to rotate around a third axis, the third axis passing through the center of the first ball joint.

[0073] For example, the first moving platform 6 is movably mounted on top of the back frame 12 in the left-right direction, and the second drive assembly 32 is mounted on top of the back frame 12 and connected to the first moving platform 6. When the second drive assembly 32 is working, it can drive the first moving platform 6 to move in the left-right direction, the first moving platform 6 can drive the connecting plate 7 to move in the left-right direction, the connecting plate 7 can drive the connecting frame 4 to rotate around the third axis through the second ball joint 5, and the connecting frame 4 can drive the circumferential field superconducting magnet 200 to rotate around the third axis. Further, the second ball joint 5 can be a spherical sliding bearing.

[0074] In this embodiment, a first moving platform 6 and a connecting plate 7 are provided in the assembly fixture 100. The first moving platform 6 is movably mounted on the support frame 1 along the second direction. The first moving platform 6 is connected to the connecting frame 4 through the connecting plate 7. A second ball joint 5 is connected between the connecting frame 4 and the connecting plate 7, so that the circumferential field superconducting magnet 200 can rotate around the third axis, thereby effectively adjusting the rotation angle of the circumferential field superconducting magnet 200 around the third axis. By providing a second driving component 32 in the driving device, the second driving component 32 is mounted on the support frame 1 and connected to the first moving platform 6 to drive the first moving platform 6 to move along the second direction, so as to drive the circumferential field superconducting magnet 200 to rotate around the third axis. The third axis passes through the center of the ball joint, which facilitates the movement of the first moving platform 6, thereby effectively improving the efficiency of rotating the circumferential field superconducting magnet 200.

[0075] In one embodiment of the present invention, such as Figure 3 As shown, one of the support frame 1 and the first moving platform 6 is provided with a first slide rail 61 and the other is provided with a first slider 121. The first slider 121 is slidably engaged with the first slide rail 61 along the second direction.

[0076] For example, a first slide rail 61 is provided on the support frame 1, and a first slider 121 is provided on the first moving platform 6; or, for example, a first slider 121 is provided on the support frame 1, and a first slide rail 61 is provided on the first moving platform 6. In a specific example, such as Figure 3 As shown, a first slider 121 is provided on the top of the back frame 12 of the support frame 1, and a first slide rail 61 is provided on the bottom of the first moving platform 6. Furthermore, there are two first sliders 121, which extend in the left and right direction and are spaced apart in the front and back direction. The first slide rail 61 corresponds to the first slider 121 one by one.

[0077] In this embodiment, a first slide rail 61 is provided on one of the support frame 1 and the first moving platform 6, and a first slider 121 is provided on the other. The first slider 121 is slidably fitted onto the first slide rail 61 along the second direction. This not only provides stable guidance for the movement of the first moving platform 6 and prevents the first moving platform 6 from deviating from the predetermined movement path, thereby effectively improving the stability of the first moving platform 6 during movement, but also effectively reduces the friction force of the first moving platform 6 during movement, thereby effectively reducing vibration and impact. This effectively protects the circumferential field superconducting magnet 200 and thus effectively improves the reliability of the assembly fixture 100.

[0078] In one embodiment of the present invention, such as Figure 4As shown, the first mobile platform 6 is provided with a first locking bracket 62, and the support frame 1 is provided with a first mating structure. The first locking bracket 62 is adapted to be connected to the first mating structure by fasteners.

[0079] In a specific example, such as Figure 4 As shown, a screw hole is provided on the right end of the first locking bracket 62, and a screw hole is provided on the left end of the first moving platform 6. The first locking bracket 62 can be fixedly connected to the left end of the first moving platform 6 by fasteners. An elongated hole is provided on the lower end of the first locking bracket 62. A first mating structure is provided on the top of the back frame 12 of the support frame 1. A screw hole is provided in the first mating structure. The first locking bracket 62 can be fixedly connected to the top of the back frame 12 by fasteners.

[0080] After the circumferential field superconducting magnet 200 rotates to a suitable position around the third axis, the first locking bracket 62 is fixedly connected to the left end of the first moving platform 6 and the top of the back frame 12 using fasteners. This allows the first moving platform 6 to be fixed to the top of the back frame 12, thereby effectively restricting the movement of the first moving platform 6 in the left and right directions.

[0081] In this embodiment, a first locking bracket 62 is provided on the first moving platform 6, and a first mating structure is provided on the support frame 1. The first locking bracket 62 is adapted to be connected to the first mating structure by fasteners. This allows the toroidal superconducting magnet 200 to be effectively fixed after it has rotated around the third axis to a suitable position. This prevents the first moving platform 6 from moving unexpectedly when it is not needed, thereby preventing the toroidal superconducting magnet 200 from rotating unexpectedly around the third axis. This also prevents the toroidal superconducting magnet 200 from colliding and interfering with the cold shield sector of the vacuum chamber. As a result, the stability of the first moving platform 6 and the safety of the toroidal superconducting magnet 200 can be effectively increased.

[0082] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the second drive assembly 32 includes: a second fixed bracket 321, a second connecting bracket 322, and a second drive member 323.

[0083] The second fixed bracket 321 is fixed to the support frame 1; the second connecting bracket 322 is fixed to the first moving platform 6; the second driving member 323 has a second fixed end and a second movable end that is movable relative to the second fixed end in a second direction, the second fixed end is hinged to the second fixed bracket 321, and the second movable end is hinged to the second connecting bracket 322.

[0084] In a specific example, such as Figure 3As shown, the second fixed bracket 321 is fixedly installed on the top right side of the back frame 12, and the second connecting bracket 322 is fixed to the right end of the first moving platform 6. The right end of the second driving member 323 is the second fixed end, and the left end of the second driving member 323 is the movable end. The second movable end of the second driving member 323 can move to the left or right relative to the second fixed end.

[0085] The second fixed end is hinged to the second fixed bracket 321, thereby allowing the second driving member 323 to rotate relative to the second fixed bracket 321 in the vertical plane. The second movable end is hinged to the second connecting bracket 322, thereby allowing the second driving member 323 to rotate relative to the second connecting bracket 322 in the vertical plane.

[0086] In other words, the hinged connection at both ends of the second drive component 323 provides the second drive component 323 with additional rotational freedom, enabling the second drive assembly 32 to adapt to certain angle changes. Even if there is a certain angle deviation between the first moving platform 6 and the support frame 1, the second drive component 323 can still work smoothly, thereby effectively improving the flexibility of the second drive assembly 32.

[0087] Furthermore, the second drive component 323 can be a double-acting hydraulic cylinder, and a displacement sensor can be installed between the cylinder body and the piston rod of the double-acting hydraulic cylinder to measure and control the precise extension and retraction movement of the hydraulic rod. The double-acting hydraulic cylinder uses a servo hydraulic control system, and the motion accuracy reaches ±0.5mm. In addition, the second drive component 323 can also be a linear servo motor or a combination of a rotary servo motor and a linear motion mechanism.

[0088] When the second driving member 323 is working, the second movable end can move in the left and right direction, thereby driving the first moving platform 6 to move in the left and right direction. The first moving platform 6 can drive the second moving platform 8 to move in the left and right direction. The second moving platform 8 can drive the connecting plate 7 to move in the left and right direction. The connecting plate 7 can drive the connecting frame 4 to rotate around the third axis through the second ball joint 5. The connecting frame 4 can drive the circumferential field superconducting magnet 200 to rotate around the third axis.

[0089] This embodiment incorporates a second fixed bracket 321, a second connecting bracket 322, and a second driving member 323 within the second drive assembly 32. The second fixed bracket 321 is fixed to the support frame 1, and the second connecting bracket 322 is fixed to the first moving platform 6. The second driving member 323 has a second fixed end and a second movable end that is movable relative to the second fixed end along a second direction. The second fixed end is hinged to the second fixed bracket 321, and the second movable end is hinged to the second connecting bracket 322. This configuration allows the second driving member 323 to possess reliable rotational freedom, thereby effectively improving the flexibility of the second drive assembly 32. Furthermore, it effectively simplifies the structural design of the second drive assembly 32, thereby significantly improving the ease of maintenance of the second drive assembly 32.

[0090] In one embodiment of the present invention, such as Figures 3-5 As shown, the assembly fixture 100 also includes: a second moving platform 8, which is movably disposed on the first moving platform 6 along a third direction, and the first moving platform 6 is connected to the connecting plate 7 through the second moving platform 8; the driving device also includes: a third driving component 33, which is disposed on the first moving platform 6 and connected to the second moving platform 8 for driving the second moving platform 8 to move along a third direction, so as to drive the circumferential field superconducting magnet 200 to rotate around a second axis, the second axis passing through the center of the first ball joint.

[0091] In a specific example, such as Figure 3 As shown, the second mobile platform 8 is movably disposed above the first mobile platform 6 along a third direction. The second mobile platform 8 is connected to the connecting plate 7, thereby enabling the first mobile platform 6 to be connected to the connecting plate 7 via the second mobile platform 8. Figure 4 As shown, the third drive component 33 is disposed on the upper side of the first mobile platform 6, and the third drive component 33 is connected to the rear end of the second mobile platform 8.

[0092] When the third drive assembly 33 is working, the third drive assembly 33 can drive the second moving platform 8 to move in the front-back direction, the second moving platform 8 can drive the connecting plate 7 to move in the front-back direction, the connecting plate 7 can drive the connecting frame 4 to rotate around the second axis through the second ball joint 5, and the connecting frame 4 can drive the circumferential field superconducting magnet 200 to rotate around the second axis.

[0093] In this embodiment, a second moving platform 8 is provided in the assembly fixture 100. The second moving platform 8 is movably disposed on the first moving platform 6 along a third direction. The first moving platform 6 is connected to the connecting plate 7 through the second moving platform 8, so that the circumferential field superconducting magnet 200 can rotate around the second axis, thereby effectively adjusting the rotation angle of the circumferential field superconducting magnet 200 around the second axis. A third driving component 33 is provided in the driving device. The third driving component 33 is disposed on the first moving platform 6 and connected to the second moving platform 8 to drive the second moving platform 8 to move along a third direction, thereby driving the circumferential field superconducting magnet 200 to rotate around the second axis. The second axis passes through the center of the first ball joint, which facilitates the movement of the second driving platform, thereby effectively improving the efficiency of rotating the circumferential field superconducting magnet 200.

[0094] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, one of the first moving platform 6 and the second moving platform 8 is provided with a second slide rail 63 and the other is provided with a second slider 81. The second slider 81 is slidably fitted onto the second slide rail 63 along a third direction.

[0095] For example, the first moving platform 6 is provided with a second slide rail 63 and the second moving platform 8 is provided with a second slider 81; or, for example, the first moving platform 6 is provided with a second slider 81 and the second moving platform 8 is provided with a second slide rail 63. In a specific example, such as Figure 3 and Figure 4 As shown, a second slide rail 63 is provided on the first moving platform 6 and a second slider 81 is provided on the second moving platform 8. Further, the second slider 81 is provided at the left and right ends of the second moving platform 8 and extends along the front and rear direction. The second slide rail 63 and the second slider 81 correspond one-to-one.

[0096] In this embodiment, a second slide rail 63 is provided on one of the first moving platform 6 and the second moving platform 8, and a second slider 81 is provided on the other. The second slider 81 is slidably fitted onto the second slide rail 63 along a third direction. This not only provides stable guidance for the movement of the second moving platform 8, preventing it from deviating from the predetermined movement path and thus effectively improving the stability of the second moving platform 8 during movement, but also effectively reduces the frictional force of the second moving platform 8 during movement, thereby effectively reducing vibration and impact. This effectively protects the circumferential field superconducting magnet 200 and further improves the reliability of the assembly fixture 100.

[0097] In one embodiment of the present invention, such as Figure 4 As shown, the second moving platform 8 is provided with a second locking bracket 82, and the first moving platform 6 is provided with a second mating structure. The second locking bracket 82 is adapted to be connected to the second mating structure by fasteners.

[0098] In a specific example, such as Figure 4 As shown, there are two second locking brackets 82, which are arranged at intervals along the left and right direction on the upper side of the second moving platform 8. Furthermore, the second locking brackets 82 are provided with screw holes, the second moving platform 8 is provided with elongated holes, and the second mating structure is provided at the left and right ends of the first moving platform 6. The second mating structure is provided with screw holes, and the screw holes on the second locking brackets 82, the elongated holes on the second moving platform 8, and the screw holes in the second mating structure are correspondingly provided.

[0099] After the circumferential field superconducting magnet 200 rotates to a suitable position around the second axis, the second locking bracket 82 is fixedly connected to the upper side of the second moving platform 8 using fasteners. In this way, the second moving platform 8 can be fixed to the upper side of the first moving platform 6, thereby effectively restricting the movement of the second moving platform 8 in the front-back direction.

[0100] In this embodiment, a second locking bracket 82 is provided on the second moving platform 8, and a second mating structure is provided on the first moving platform 6. The second locking bracket 82 is adapted to be connected to the second mating structure by fasteners. This allows the toroidal field superconducting magnet 200 to be effectively fixed after it has rotated around the second axis to a suitable position. This prevents the second moving platform 8 from moving unexpectedly when it is not needed, thereby preventing the toroidal field superconducting magnet 200 from rotating unexpectedly around the second axis. This also prevents the toroidal field superconducting magnet 200 from colliding and interfering with the cold screen sector of the vacuum chamber. As a result, the stability of the second moving platform 8 and the safety of the toroidal field superconducting magnet 200 can be effectively increased.

[0101] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the third drive assembly 33 includes: a third fixed bracket 331, a third connecting bracket 332, and a third drive component 333.

[0102] The third fixed bracket 331 is fixed to the first moving platform 6; the third connecting bracket 332 is fixed to the second moving platform 8; the third driving member 333 has a third fixed end and a third movable end that is movable relative to the third fixed end along a third direction, the third fixed end is hinged to the third fixed bracket 331, and the third movable end is hinged to the third connecting bracket 332.

[0103] In a specific example, such as Figure 4 As shown, the third fixed bracket 331 is located at the rear of the second moving platform 8 and fixed to the upper side of the first moving platform 6, and the third connecting bracket 332 is fixed to the rear end of the second moving platform 8. The third movable end of the third driving member 333 can move forward or backward relative to the third fixed end.

[0104] The third fixed end is hinged to the third fixed bracket 331, thereby allowing the third driving member 333 to rotate in the vertical plane relative to the third fixed bracket 331. The third movable end is hinged to the third connecting bracket 332, thereby allowing the third driving member 333 to rotate in the vertical plane relative to the third connecting bracket 332.

[0105] In other words, the hinged connection between the third drive component 333 and the third fixed bracket 331 and the third connecting bracket 332 provides the third drive component 333 with additional rotational freedom, enabling the third drive component 33 to adapt to certain angle changes. Even if there is a certain angle deviation between the second moving platform 8 and the first moving platform 6, the third drive component 333 can still work smoothly, thereby effectively improving the flexibility of the third drive component 33.

[0106] Furthermore, the third drive component 333 can be a double-acting hydraulic cylinder, with a displacement sensor installed between the cylinder body and the piston rod to measure and control the precise extension and retraction of the hydraulic rod. The double-acting hydraulic cylinder uses a servo hydraulic control system, achieving a motion accuracy of ±0.5mm. Additionally, the third drive component 333 can also be a linear servo motor or a combination of a rotary servo motor and a linear motion mechanism.

[0107] When the third driving component 333 is working, the third movable end can move in the front-back direction, thereby driving the second moving platform 8 to move in the front-back direction. The second moving platform 8 can drive the connecting plate 7 to move in the front-back direction. The connecting plate 7 can drive the connecting frame 4 to rotate around the second axis through the second ball joint 5. The connecting frame 4 can drive the circumferential field superconducting magnet 200 to rotate around the second axis.

[0108] This embodiment, by providing a third fixed bracket 331, a third connecting bracket 332, and a third driving member 333 in the third drive assembly 33, with the third fixed bracket 331 fixed to the first moving platform 6 and the third connecting bracket 332 fixed to the second moving platform 8, and the third driving member 333 having a third fixed end and a third movable end movable relative to the third fixed end along a third direction, with the third fixed end hinged to the third fixed bracket 331 and the third movable end hinged to the third connecting bracket 332, enables the third driving member 333 to have reliable rotational freedom, thereby effectively improving the flexibility of the third drive assembly 33. Furthermore, it effectively simplifies the structural construction of the third drive assembly 33, thereby effectively improving the convenience of maintenance of the third drive assembly 33.

[0109] In one embodiment of the present invention, such as Figures 3-5As shown, the first direction is the up-down direction. The connecting plate 7 is arranged on the upper side of the connecting frame 4 and the second moving platform 8. The connecting frame 4 and the second moving platform 8 are connected by multiple hinges in the third direction and are arranged at intervals. One end of the connecting plate 7 is detachably connected to the connecting frame 4, and the other end of the connecting plate 7 is rotatable relative to the second moving platform 8 about an axis extending along the second direction between the connected position and the open position. In the connected position, the connecting plate 7 is adapted to be connected to the connecting frame 4. When the connecting plate 7 is separated from the connecting frame 4, the connecting plate 7 can be rotated to the open position. In the open position, the connecting plate 7 and the connecting frame 4 are offset in the third direction. The assembly fixture 100 also includes: a fourth drive assembly 9, which is disposed on the second moving platform 8 and connected to the connecting plate 7, for driving the connecting plate 7 to rotate between the connected position and the open position.

[0110] In a specific example, such as Figure 5 As shown, the connecting plate 7 is disposed on the upper side of the second moving platform 8, and the rear end of the connecting plate 7 is hinged to the front end of the second moving platform 8 at multiple points. That is, the front end of the connecting plate 7 can rotate relative to the second moving platform 8 about an axis extending in the left-right direction between a connected position and an open position. For example, the number of hinged connections between the rear end of the connecting plate 7 and the front end of the second moving platform 8 can be two, three, four, five, or more than six. In a specific example, such as... Figure 5 As shown, the number of hinged connections between the rear end of the connecting plate 7 and the front end of the second mobile platform 8 can be two.

[0111] When the connecting plate 7 is in the open position, the connecting plate 7 is separated from the second ball joint 5 and the connecting plate 7 is located on the rear side of the connecting frame 4, which facilitates the installation or removal of the circumferential field superconducting magnet 200 on the support frame 1. When the connecting plate 7 is in the connected position, the connecting plate 7 is rotatably connected to the connecting frame 4 through the second ball joint 5. At this time, the fourth drive assembly 9 can drive the connecting plate 7 to move in the front-back direction or the left-right direction, thereby causing the connecting frame 4 and the circumferential field superconducting magnet 200 to rotate around the third axis or the second axis.

[0112] Furthermore, the connecting plate 7 can rotate at an angle greater than or equal to 0° and less than or equal to 100°. In a specific example, such as... Figure 5 As shown, in the direction from right to left, when the connecting plate 7 is in a horizontal position, the rotation angle of the connecting plate 7 is defined as 0°. At the same time, the angle when the connecting plate 7 rotates clockwise is defined as positive, and the angle when the connecting plate 7 rotates counterclockwise is defined as negative. Therefore, the rotation angle range of the connecting plate 7 can be from -5° to 95°.

[0113] In this embodiment, the connecting plate 7 is arranged on the upper side of the connecting frame 4 and the second moving platform 8. The connecting frame 4 and the second moving platform 8 are hinged at multiple points in the third direction and arranged at intervals. One end of the connecting plate 7 is detachably connected to the connecting frame 4, and the other end of the connecting plate 7 is rotatable relative to the second moving platform 8 about an axis extending along the second direction between a connected position and an open position. In the connected position, the connecting plate 7 is adapted to be connected to the connecting frame 4. When the connecting plate 7 is separated from the connecting frame 4, the connecting plate 7 can be rotated to the open position. In the open position, the connecting plate 7 and the connecting frame 4 are staggered in the third direction, which allows the connecting plate 7 to rotate between the connected position and the open position. This facilitates the installation or removal of the circumferential field superconducting magnet 200 on the support frame 1, thereby effectively improving the convenience of operation. By providing a fourth driving component 9 in the assembly fixture 100, the fourth driving component 9 is located on the second moving platform 8 and connected to the connecting plate 7. It is used to drive the connecting plate 7 to rotate between the connected position and the open position, which facilitates the rotation of the connecting plate 7 and effectively improves the efficiency of rotating the connecting plate 7.

[0114] In one embodiment of the present invention, such as Figure 5 As shown, the fourth drive assembly 9 includes: a fourth fixed bracket 91, a fourth connecting bracket 92, and a fourth drive member 93.

[0115] The fourth fixed bracket 91 is fixed to the second moving platform 8; the fourth connecting bracket 92 is fixed to the connecting plate 7; the fourth driving member 93 has a fourth fixed end and a fourth movable end that is movable relative to the fourth fixed end along a third direction, the fourth fixed end is hinged to the fourth fixed bracket 91, and the fourth movable end is hinged to the fourth connecting bracket 92.

[0116] In a specific example, such as Figure 5 As shown, the fourth fixed bracket 91 is fixed to the upper side of the second moving platform 8 and located at the rear end of the second moving platform 8, and the fourth connecting bracket 92 is fixed to the upper side of the connecting plate 7 and located at the rear end of the connecting plate 7. The fourth movable end of the fourth driving member 93 can move linearly relative to the fourth fixed end.

[0117] The fourth fixed end is hinged to the fourth fixed bracket 91, thereby allowing the fourth driving member 93 to rotate in the vertical plane relative to the fourth fixed bracket 91. The fourth movable end is hinged to the fourth connecting bracket 92, thereby allowing the fourth driving member 93 to rotate in the vertical plane relative to the fourth connecting bracket 92.

[0118] In other words, the hinged connection between the fourth drive component 93 and the fourth fixed bracket 91 and the fourth connecting bracket 92 provides the fourth drive component 93 with additional rotational freedom, enabling the fourth drive assembly 9 to adapt to certain angle changes. Even if there is a certain angle deviation between the connecting plate 7 and the second moving platform 8, the fourth drive component 93 can still work smoothly, thereby effectively improving the flexibility of the fourth drive assembly 9.

[0119] Furthermore, the fourth drive unit 93 can be a double-acting hydraulic cylinder. Alternatively, the fourth drive unit 93 can be a linear servo motor or a combination of a rotary servo motor and a linear motion mechanism. When the fourth drive unit 93 is in operation, the fourth movable end can move linearly relative to the fourth fixed end, thereby driving the rear end of the connecting plate 7 to rotate relative to the second moving platform 8 about an axis extending in the left-right direction between a connected position and an open position.

[0120] This embodiment, by providing a fourth fixed bracket 91, a fourth connecting bracket 92, and a fourth driving member 93 in the fourth drive assembly 9, with the fourth fixed bracket 91 fixed to the second moving platform 8, the fourth connecting bracket 92 fixed to the connecting plate 7, and the fourth driving member 93 having a fourth fixed end and a fourth movable end movable relative to the fourth fixed end along a third direction, with the fourth fixed end hinged to the fourth fixed bracket 91 and the fourth movable end hinged to the fourth connecting bracket 92, enables the fourth driving member 93 to have reliable rotational freedom, thereby effectively improving the flexibility of the fourth drive assembly 9. Furthermore, it effectively simplifies the structural construction of the fourth drive assembly 9, thereby effectively improving the convenience of maintenance of the fourth drive assembly 9.

[0121] In one embodiment of the present invention, such as Figure 5 As shown, one of the connecting plate 7 and the second moving platform 8 is provided with a first locking hole 83 and the other is provided with a first locking pin 71. When the connecting plate 7 is in the open position, the first locking pin 71 is adapted to fit into the first locking hole 83 so that the connecting plate 7 and the second moving platform 8 are relatively fixed.

[0122] For example, the connecting plate 7 is provided with a first locking hole 83 and the second moving platform 8 is provided with a first locking pin 71; or, for example, the connecting plate 7 is provided with a first locking pin 71 and the second moving platform 8 is provided with a first locking hole 83. In a specific example, such as Figure 5 As shown, the connecting plate 7 is provided with a first locking pin 71 and the second moving platform 8 is provided with a first locking hole 83.

[0123] When the connecting plate 7 is in the open position, the first locking pin 71 can be inserted into the first locking hole 83, thereby fixing the connecting plate 7 relative to the second moving platform 8. This ensures that the connecting plate 7 will not rotate accidentally when in the open position, so as to facilitate maintenance and adjustment of the assembly fixture 100.

[0124] In this embodiment, a first locking hole 83 is provided on one of the connecting plate 7 and the second moving platform 8, and a first locking pin 71 is provided on the other. When the connecting plate 7 is in the open position, the first locking pin 71 is adapted to engage with the first locking hole 83, so that the connecting plate 7 and the second moving platform 8 are relatively fixed. This effectively fixes the connecting plate 1057 when the connecting plate 7 is in the open position, preventing the connecting plate 7 from rotating due to external factors, thereby facilitating the maintenance and adjustment of the assembly fixture 100. In addition, it can effectively simplify the locking or unlocking process of the connecting plate 7, thereby effectively improving the convenience of operation.

[0125] In one embodiment of the present invention, such as Figure 6 and Figure 7 As shown, the connecting plate 7 is detachably connected to the connecting frame 4 via the connecting assembly 10. A connecting hole is formed on the connecting plate 7, which extends through the connecting plate 7 in a first direction. The connecting assembly 10 includes a connecting shaft 101 and a connecting block 102. The connecting shaft 101 extends in the first direction. One end of the connecting shaft 101 is fixed to the second ball joint 5, and the other end of the connecting shaft 101 passes through the connecting hole. A connecting boss 1011 is formed on the outer circumferential surface of the connecting shaft 101, which protrudes radially outward. The connecting boss 1011 is located between the connecting plate 7 and the second ball joint 5. The connecting block 102 is sleeved on the other end of the connecting shaft 101 and is located on the side of the connecting plate 7 opposite to the second ball joint 5. The connecting block 102, the connecting plate 7, and the connecting boss 1011 are connected by fasteners.

[0126] The connecting plate 7 is detachably connected to the connecting frame 4 via the connecting assembly 10. This means that when the toroidal field superconducting magnet 200 needs to be installed or removed from the support frame 1, the connecting plate 7 can be separated from the connecting frame 4; when the rotation angle of the toroidal field superconducting magnet 200 needs to be adjusted on the support frame 1, the connecting plate 7 and the connecting frame 4 can be connected together. This facilitates the maintenance and adjustment of the toroidal field superconducting magnet 200.

[0127] In a specific example, such as Figure 6 and Figure 7 As shown, a connecting hole is formed on the connecting plate 7 in the vertical direction, the connecting shaft 101 extends in the vertical direction, the lower end of the connecting shaft 101 is fixed to the second ball joint 5, the upper end of the connecting shaft 101 passes through the connecting hole, and the connecting boss 1011 on the outer circumference of the connecting shaft 101 is located on the lower side of the connecting plate 7 and abuts against the connecting plate 7 in the vertical direction.

[0128] In a specific example, for example Figure 6As shown, the connecting block 102 is disposed on the upper side of the connecting plate 7. The connecting block 102 consists of a first connecting block 102 and a second connecting block 102. The first connecting block 102 and the second connecting block 102 are arranged at intervals on both sides of the connecting shaft 101 in the front-rear direction and are in close contact with the outer peripheral surface of the connecting shaft 101. Both the first connecting block 102 and the second connecting block 102 are provided with screw holes, and fasteners are disposed in the screw holes. By tightening the fasteners, the connecting block 102, the connecting plate 7, and the connecting boss 1011 can be fixedly connected together, thereby connecting the connecting plate 7 and the connecting bracket 4 together. When it is necessary to separate the connecting plate 7 and the connecting bracket, the fasteners in the screw holes of the connecting block 102 can be loosened to separate the connecting block 102 and the connecting shaft 101 from the connecting plate 7, thereby separating the connecting plate 7 from the connecting bracket 4.

[0129] Furthermore, the connecting assembly 10 also includes an upper pressure plate 103, a lower baffle 104, and a fixed connecting plate 1057. The lower baffle 104 is disposed at the lower end of the connecting shaft 101, the upper pressure plate 103 is disposed outside the second ball joint 5 and located above the fixed connecting plate 1057, and the fixed connecting plate 1057 is fixedly connected to the connecting frame 4.

[0130] In this embodiment, the connecting plate 7 is detachably connected to the connecting frame 4 via the connecting assembly 10. The connecting plate 7 has a connecting hole extending through it in a first direction. The connecting assembly 10 includes a connecting shaft 101 and a connecting block 102. The connecting shaft 101 extends in the first direction, with one end fixed to the second ball joint 5 and the other end passing through the connecting hole. A connecting boss 1011, protruding radially outward, is formed on the outer circumferential surface of the connecting shaft 101, located between the connecting plate 7 and the second ball joint 5. The connecting block 102 is fitted onto the other end of the connecting shaft 101 and located on the side of the connecting plate 7 opposite to the second ball joint 5. The connecting block 102, the connecting plate 7, and the connecting boss 1011 are connected by fasteners. This not only ensures a firm and reliable connection between the connecting plate 7 and the connecting frame 4, effectively improving the reliability of the connection, but also facilitates the connection or separation of the connecting plate 7 and the connecting frame 4, thereby significantly improving operational convenience.

[0131] An assembly method for a toroidal field superconducting magnet 200 of a nuclear fusion device according to a second aspect of the present invention, the assembly method being applied to an assembly fixture 100 of the first aspect of the present invention, the assembly method comprising: S1, fixing the toroidal field superconducting magnet 200 onto the assembly fixture 100.

[0132] In a specific example, when using the assembly fixture 100 of this application to install the toroidal superconducting magnet 200 of the nuclear fusion device, the toroidal superconducting magnet 200 is first fixed onto the assembly fixture 100, and then the vacuum chamber is hoisted to the preset position by the sector overall hoisting fixture. In this way, the preparatory work before the installation and adjustment of the toroidal superconducting magnet 200 of the nuclear fusion device can be completed.

[0133] S2, the circumferential field superconducting magnet 200 is driven to rotate around the first axis, the second axis and / or the third axis by the assembly fixture 100, so as to adjust the installation angle and position of the driven circumferential field superconducting magnet 200.

[0134] When the toroidal field superconducting magnet 200 is adjusted using the drive device of the assembly fixture 100, the drive device can drive the toroidal field superconducting magnet 200 and the support frame 2 to rotate relative to the support frame 1. For example, the drive device can drive the toroidal field superconducting magnet 200 and the support frame 2 to rotate relative to the support frame 1 about any one of the first axis, the second axis, and the third axis; or, for example, the drive device can drive the toroidal field superconducting magnet 200 and the support frame 2 to rotate relative to the support frame 1 about any two of the first axis, the second axis, and the third axis; or, for yet another example, the drive device can drive the toroidal field superconducting magnet 200 and the support frame 2 to rotate relative to the support frame 1 about the first axis, the second axis, and the third axis. Furthermore, the sector-wide hoisting fixture can adjust the position of the vacuum chamber to meet the adjustment requirements during the assembly of the vacuum chamber and the toroidal field superconducting magnet 200.

[0135] S3, the assembly fixture 100 moves along the circular track to assemble with the vacuum chamber.

[0136] In a specific example, the bottom of the support platform 11 is connected to three pairs of pulley assemblies, and the support frame 1 is mounted on three annular tracks through the three pairs of pulley assemblies. The assembly fixture 100 can make the circumferential field superconducting magnet 200 move slowly along the annular tracks through the cooperation of the pulley assemblies and the annular tracks, and finally assemble it with the vacuum chamber.

[0137] According to the assembly method of the toroidal superconducting magnet 200 of the nuclear fusion device according to the second aspect of the present invention, when assembling the toroidal superconducting magnet 200 of the nuclear fusion device, the toroidal superconducting magnet 200 is first fixed to the assembly fixture 100, and then the assembly fixture 100 drives the toroidal superconducting magnet 200 to rotate around the first axis, the second axis and / or the third axis to adjust the installation angle and position of the toroidal superconducting magnet 200. Finally, the assembly fixture 100 is moved along the annular track to be assembled with the vacuum chamber. This method can effectively adjust the rotation angle of the toroidal superconducting magnet 200 around the first axis, the second axis and / or the third axis when installing the toroidal superconducting magnet 200 of the nuclear fusion device, thereby meeting the assembly requirements of the toroidal superconducting magnet 200 and effectively improving the installation effect and assembly efficiency.

[0138] In one embodiment of the present invention, S1 includes: S11, rotating the connecting plate 7 of the assembly fixture 100 to the open position and locking the connecting plate 7.

[0139] In a specific example, the front end of the connecting plate 7 can be rotated to the open position relative to the second moving platform 8 about an axis extending in the left and right direction using a hoisting tool. Then, the first locking pin 71 is inserted into the first locking hole 83 to lock the connecting plate 7, thereby fixing the connecting plate 7 relative to the second moving platform 8. This ensures that the connecting plate 7 will not rotate accidentally when in the open position, so as to fix the circumferential field superconducting magnet 200 onto the assembly fixture 100.

[0140] S12, hoist the circumferential field superconducting magnet 200 to the assembly fixture 100 and fix it on the support frame 2.

[0141] For example, the toroidal field superconducting magnet 200 can be hoisted onto the support frame 2 using hoisting tools; that is, as... Figure 2 As shown, the bottom of the toroidal superconducting magnet 200 is supported on the top of the support frame 2. Then, the bottom of the toroidal superconducting magnet 200 is fixedly connected to the support frame 2, so that the toroidal superconducting magnet 200 can rotate together with the support frame 2.

[0142] S13, unlock the connecting plate 7, and rotate the connecting plate 7 to the connecting position.

[0143] In a specific example, the first locking pin 71 is disengaged from the first locking hole 83, and then, using a hoisting tool, the front end of the connecting plate 7 is rotated relative to the second moving platform 8 about an axis extending in the left-right direction to the connection position. For example... Figure 3 and Figure 5 As shown, the connecting plate 7 is in the connecting position, and then the connecting plate 7 can be rotatably connected to the connecting frame 4 through the connecting assembly 10.

[0144] S14, fix the connecting frame 4 of the circumferential field superconducting magnet 200 to the assembly fixture 100, and fix the first connecting bracket 312 of the circumferential field superconducting magnet 200 to the multiple first driving components 31.

[0145] For example, the connecting frame 4 is first fixedly connected to the upper part of the toroidal field superconducting magnet 200, so that the connecting frame 4 and the toroidal field superconducting magnet 200 can rotate together. Then, the toroidal field superconducting magnet 200 is fixedly connected to the first connecting bracket 312 of the multiple first driving components 31, so that the driving device can drive the toroidal field superconducting magnet 200, the support frame 2 and the connecting frame 4 to rotate around the first axis, the second axis and / or the third axis, so as to adjust the installation angle and position of the driving toroidal field superconducting magnet 200.

[0146] In this embodiment, when the toroidal superconducting magnet 200 is fixed to the assembly fixture 100, the connecting plate 7 of the assembly fixture 100 is first rotated to the open position and locked. Then, the toroidal superconducting magnet 200 is hoisted onto the assembly fixture 100 and fixedly supported on the support frame 2. Next, the connecting plate 7 is unlocked and rotated to the connection position. Finally, the toroidal superconducting magnet 200 is fixed to the connecting frame 4 of the assembly fixture 100, and the toroidal superconducting magnet 200 is fixed to the first connecting bracket 312 of the multiple first drive components 31. This allows the toroidal superconducting magnet 200 to be effectively fixed to the assembly fixture 100, and can effectively ensure the fixing effect, thereby effectively improving reliability and safety.
