Description

Technical Field

[0001] This invention relates to the field of nuclear fusion device component transfer technology, and in particular to a transfer device and transfer method for transferring poloidal field coils of a nuclear fusion device. Background Technology

[0002] In the field of nuclear fusion research, poloidal field (PF) coils play an indispensable role in the operation of nuclear fusion devices. The PF coils are responsible for providing ohmic heating during the various stages of plasma generation, rise, shaping, and flattening, and for precisely controlling the plasma configuration. During operation, liquid helium at 4.2K (-269℃) is passed through the PF conductors, carrying a current of up to 45kA. The poloidal field (PF) coil system consists of six independent coils of different sizes, numbered from top to bottom as PF1, PF2, PF3, PF4, PF5, and PF6.

[0003] Among related technologies, the PF5 coil possesses unique and stringent characteristics. Its overall dimensions are enormous, reaching Φ10.8×3m, and its weight is a staggering approximately 147t. During transportation, to ensure the safety and stable performance of the PF5 coil, the transport speed must be strictly controlled to less than 1km / h. Furthermore, the installation accuracy of the superconducting connectors requires extremely high precision, with errors controlled within ±0.5mm, and both the dynamic load factor and the off-center load factor being 1.0. However, the transfer fixtures and methods used in related technologies are insufficient to meet such stringent requirements. Summary of the Invention

[0041] Among related technologies, the PF5 coil possesses unique and stringent characteristics. Its overall dimensions are enormous, reaching Φ10.8×3m, and its weight is a staggering approximately 147t. During transportation, to ensure the safety and stable performance of the PF5 coil, the transport speed must be strictly controlled to less than 1km / h. Furthermore, the installation accuracy of the superconducting connectors requires extremely high precision, with errors controlled within ±0.5mm, and both the dynamic load factor and the off-center load factor being 1.0. However, the transfer fixtures and methods used in related technologies are insufficient to meet such stringent requirements.

[0042] The following is for reference. Figures 1-8 The transfer device 1 according to an embodiment of the present invention is described.

[0043] like Figures 1-7 As shown, the transfer device 1 according to the present invention is used to transfer the poloidal field coil 2 of a nuclear fusion device. The transfer device 1 includes a moving mechanism 11, a supporting mechanism 12, a supporting member 13, and a limiting member 14. The moving mechanism 11 provides the transfer device 1 with mobility, enabling the transfer device 1 to carry the poloidal field coil 2 between different locations. The moving mechanism 11 needs to have stable mobility, be able to adapt to different road conditions, and its moving speed can be adjusted according to actual needs to meet the strict speed requirements during the transfer of the poloidal field coil 2.

[0044] The support mechanism 12 is fixedly mounted on the moving mechanism 11. Multiple support arms 121, spaced circumferentially and extending radially, are formed on the support mechanism 12. The support arms 121 provide a fixed position and direction of extension for the subsequent installation of the support component 13, supporting the poloidal field coil 2 from multiple directions to ensure the stability of the poloidal field coil 2 during transport. The circumferential spacing evenly distributes the weight of the poloidal field coil 2, while the radial extension facilitates adjustment and support according to the size and shape of the poloidal field coil 2.

[0045] The support members 13 are configured in multiple ways, each corresponding to one of the support arms 121, meaning that one support member 13 is mounted on each support arm 121. Each support member 13 is movable in the extending direction of the support arm 121, so the position of the support member 13 on the support arm 121 can be adjusted according to the actual size and shape of the poloidal field coil 2, allowing the support member 13 to accurately reach the appropriate support point, thereby better supporting the poloidal field coil 2. Each support member 13 defines a clamping cavity 134 for accommodating at least a portion of the poloidal field coil 2. The clamping cavity 134 is used to fix the poloidal field coil 2 to the support member 13, preventing the poloidal field coil 2 from shaking or shifting during transportation.

[0046] The limiting member 14 is constructed in multiple ways, each corresponding to one of the support arms 121; that is, each support arm 121 is provided with a limiting member 14. Each limiting member 14, located on the support arm 121, provides a fixed point for subsequent connection and adjustment with the support member 13. The limiting member 14 is connected to the support member 13 via an adjusting member 15, which is used to adjust the distance between the support member 13 and the limiting member 14. By adjusting the distance between the support member 13 and the limiting member 14, multiple support members 13 can clamp the poloidal coil 2 at multiple positions in the circumferential direction. The position of each support member 13 can be adjusted according to the actual size of the poloidal coil 2 to ensure that the poloidal coil 2 receives uniform and appropriate support force in the circumferential direction, further ensuring the stability and safety of the poloidal coil 2 during transportation.

[0047] By adjusting the position of the support member 13 by adjusting the adjustment member 15, the poloidal coil 2 can maintain an accurate position during transportation, avoiding a decrease in installation accuracy due to shaking or displacement.

[0048] Therefore, the transfer device 1 according to the present invention can meet the transfer requirements of the large-sized, heavy-weight, and demanding poloidal field coil 2, and ensure that the poloidal field coil 2 is accurately positioned and subjected to reasonable force during the transfer process, thus meeting the requirements of dynamic load factor and off-center load factor.

[0049] According to some embodiments of the present invention, such as Figures 5-7As shown, each limiting member 14 is disposed on at least one side of the corresponding support arm 121 in the radial direction and extends in the height direction. Therefore, the limiting member 14 can be installed on one side of the support arm 121 in the radial direction or on both sides, and has a certain length in the height direction perpendicular to the horizontal plane, so that the limiting member 14 can provide stable fixing and guiding function for subsequent adjustment and support in the radial direction.

[0050] Each adjusting member 15 extends radially, meaning its length direction aligns with the radial direction of the support mechanism 12. Each adjusting member 15 has an adjusting block 151 at its end, suitable for contacting the surface of the support member 13. The adjusting block 151 increases the contact area between the adjusting member 15 and the support member 13, making the force distribution more uniform and stable during adjustment, thus improving adjustment accuracy. The adjusting member 15 is movably connected to a corresponding limiting member 14. This movable connection can be a threaded connection, a slide rail connection, etc. Through this movable connection, the adjusting member 15 can move under the constraint of the limiting member 14, thereby adjusting the radial position of the adjusting block 151.

[0051] When it is necessary to adjust the radial position of the support member 13, the adjusting member 15 is operated. Since the adjusting member 15 is movably connected to the limiting member 14, the adjusting member 15 will move radially under the guidance of the limiting member 14. The adjusting block 151 at the end of the adjusting member 15 is in contact with the surface of the support member 13. As the adjusting member 15 moves, the adjusting block 151 will push the support member 13 to move radially. In this way, the position of the support member 13 can be precisely adjusted according to the actual size and shape of the poloidal field coil 2, so that the support member 13 can accurately support and fix the poloidal field coil 2, ensuring the stability of the poloidal field coil 2 during transportation and meeting the requirements of dynamic load factor and off-center load factor.

[0052] For example, if the adjusting member 15 and the corresponding limiting member 14 are connected by threads, the adjusting member 15 is provided with external threads, and the limiting member 14 is provided with corresponding internal threaded holes. By rotating the adjusting member 15, the adjusting member 15 can move radially within the limiting member 14, thereby driving the adjusting block 151 to move. It should be noted that the above exemplary description is only for the purpose of understanding one possible connection and adjustment method between the adjusting member 15 and the limiting member 14, and does not constitute any limitation on the connection method and adjustment principle of the two.

[0053] According to some embodiments of the present invention, such as Figure 6 As shown, the adjustment member 15 is constructed as multiple members spaced apart in the height direction, which can adjust the support member 13 at different height levels so that the support member 13 can fit the surface of the poloidal field coil 2 at different heights, thereby better supporting the poloidal field coil 2 and ensuring the stability of the poloidal field coil 2 during transportation.

[0054] According to some embodiments of the present invention, such as Figure 6 As shown, each support member 13 includes a base plate 131, a clamping plate 132, and a top plate 133. The base plate 131 is movably disposed in the extending direction of the support arm 121, so that the base plate 131 can drive the entire support member 13 to move radially along the support arm 121. By moving the base plate 131 to change the position of the support member 13, the position of the poloidal field coil 2 can be adjusted, which can keep the poloidal field coil 2 in an accurate position during transportation and avoid the decrease in installation accuracy due to shaking or displacement.

[0055] The clamping plate 132 is detachably mounted on the base plate 131, facilitating its replacement. By replacing the clamping plate 132 with different sizes, the size of the clamping cavity 134 can be adjusted to accommodate poloidal field coils 2 of different sizes. The clamping plates 132 are constructed as two plates spaced apart in the radial direction, which can clamp the poloidal field coil 2 from both sides, providing a stable and uniform clamping force to prevent the poloidal field coil 2 from moving or shaking in the radial direction, ensuring the stability of the object during transportation and installation.

[0056] A top plate 133 is disposed on two clamping plates 132 and is parallel to and spaced apart from the bottom plate 131 in the height direction, thereby defining a clamping cavity 134 between the top plate 133, the bottom plate 131, and the two clamping plates 132. The poloidal coil 2 can be placed inside the clamping cavity 134. The top plate 133 and the bottom plate 131 are connected by an adjusting rod 135, which is adapted to adjust the distance between the top plate 133 and the bottom plate 131. By adjusting the distance between the top plate 133 and the bottom plate 131 by adjusting the adjusting rod 135, clamping plates 132 of different sizes can be replaced according to the actual height of the poloidal coil 2 to adapt to the actual height of the poloidal coil 2. This allows the bottom plate 131, the top plate 133, and the clamping plates 132 to fit more tightly against the poloidal coil 2, so as to jointly apply a suitable clamping force to the object, restrict the movement of the poloidal coil 2, and further improve the stability and reliability of clamping.

[0057] According to some embodiments of the present invention, such as Figure 6 As shown, an isolation layer 136 is provided on the inner surface of the clamping plate 132 facing the clamping cavity 134. The isolation layer 136 is adapted to contact the poloidal field coil 2. By providing the isolation layer 136, the isolation layer 136 can protect the poloidal field coil 2 and realize the protection of the structural integrity of the poloidal field coil 2.

[0058] The insulating layer 136 has a certain degree of flexibility and elasticity, and can closely adhere to the surface of the poloidal field coil 2 to form a uniform protective layer. When subjected to external impact during transportation, the insulating layer 136 can undergo elastic deformation, absorbing and dispersing part of the impact energy, playing a buffering and shock-absorbing role, protecting the structural integrity of the poloidal field coil 2, and ensuring that the insulation layer of the poloidal field coil 2 is not damaged during transportation.

[0059] The isolation layer 136 has a low coefficient of friction. During transportation, when there is slight relative movement or vibration between the poloidal field coil 2 and the clamping plate 132, the friction between them can be reduced, thus lowering the risk of wear on the surface of the poloidal field coil 2.

[0060] Exemplarily, the insulating layer 136 is constructed as a polytetrafluoroethylene (PTFE) layer. PTFE layers possess excellent chemical stability, a low coefficient of friction, and good flexibility and elasticity, which meets the requirements for insulating layer 136. It should be noted that the above exemplary description is merely to aid in understanding the preferred embodiment of insulating layer 136 in this invention and is not intended to limit the invention. In practical applications, insulating layer 136 can also be made of other materials with similar properties, as long as they can meet the requirements of protecting the pole-oriented field coil 2, providing buffering and shock absorption effects, and reducing the coefficient of friction.

[0061] According to some embodiments of the present invention, such as Figure 7 As shown, the support mechanism 12 includes an outer ring beam 122 and an inner ring beam 123. Multiple outer ring beams 122 are constructed, each connecting one end of a plurality of adjacent support arms 121. The outer ring beams 122 converge and fix one end of the plurality of support arms 121 together, forming a unified connection node. For example, if there are 12 support arms 121, the outer ring beams 122 may connect one end of 3 or 4 adjacent support arms 121, the specific number of connections depending on the design layout and stress requirements.

[0062] The inner ring beams 123 are configured in multiple ways, each corresponding to one of the outer ring beams 122. Each inner ring beam 123 is parallel to its corresponding outer ring beam 122 and connects to the other ends of multiple adjacent support arms 121. In other words, the inner ring beams 123 serve to converge and fix the other ends of the support arms 121, echoing the outer ring beams 122 and working together to securely connect the two ends of the support arms 121. For example, the inner ring beams 123 corresponding to the outer ring beams 122 that connect one end of three support arms 121 will connect to the other ends of these three support arms 121.

[0063] The outer ring beam 122 and inner ring beam 123, connected to the support arm 121, form a stable, ring-like support frame, providing a comprehensive support foundation for the poloidal field coil 2. This frame can withstand the weight of the poloidal field coil 2 and various external forces generated during transport. When the poloidal field coil 2 is placed on the support structure composed of the support arm 121, outer ring beam 122, and inner ring beam 123, its weight is evenly distributed to the outer ring beam 122 and inner ring beam 123 through the support arm 121. The outer ring beam 122 and inner ring beam 123 then transmit this force to the moving mechanism 11, better resisting forces during transport and ensuring that the support mechanism 12 remains stable under various working conditions, providing reliable support for the poloidal field coil 2.

[0064] According to some embodiments of the present invention, such as Figure 7 As shown, multiple support arms 121 are arranged in a centrally symmetrical manner, ensuring that the support structure has the same geometric characteristics and mechanical properties in all directions. The central angle between any two adjacent support arms 121 is 360° / n, where n is the number of support arms 121. Since a complete circle is 360°, when there are n support arms 121 evenly distributed on this circle, the formula for calculating the central angle is obtained by distributing 360° evenly between every two adjacent support arms 121.

[0065] If the number of support arms 121 is n=12, then the central angle between any two adjacent support arms 121 is 360°÷12=30°. Therefore, the angle between any two adjacent support arms 121 on the circumference around the center point is 30°. The 12 support arms 121 divide the entire circumference into 12 equal parts.

[0066] During the transfer of the poloidal field coil 2, the weight of the poloidal field coil 2 and various external forces generated during the transfer process will act on the support arm 121. Since the support arms 121 are centrally symmetrically distributed and the central angle between adjacent support arms 121 is fixed, the force can be evenly distributed to each support arm 121.

[0067] After determining the actual dimensions of the poloidal coil 2 and the distribution characteristics of the support arms 121, the distance between the support member 13 and the limiting member 14 can be adjusted using the adjusting member 15 equipped on each support arm 121. By adjusting the position of the support member 13, it is moved in the extension direction of the support arm 121, ensuring that the support member 13 can reach a suitable support point. The support point is calculated and designed so that the support member 13 can stably fit against the outer surface of the poloidal coil 2, providing uniform and stable support force for the poloidal coil 2. In this way, regardless of the size of the poloidal coil 2, it can receive reliable and effective support during the transfer process, ensuring the smooth progress of the transfer work and the accuracy and quality of the subsequent installation of the nuclear fusion device.

[0068] According to some embodiments of the present invention, such as Figure 7 As shown, the support mechanism 12 also includes a connecting portion 124. The connecting portion 124 is positioned at the symmetrical center of the plurality of support arms 121, resulting in a more balanced mechanical distribution of the support mechanism 12. Multiple connecting arms 125 extend radially from the connecting portion 124, each connecting arm 125 connecting to the other end of a support arm 121, thereby tightly connecting the connecting portion 124 to the plurality of support arms 121. The number of connecting arms 125 corresponds to the number of support arms 121; the correspondence can be one-to-one, or one connecting arm 125 can correspond to multiple support arms 121.

[0069] When one connecting arm 125 corresponds to one support arm 121, the load from the poloidal field coil 2 borne by each support arm 121 can be accurately and independently transmitted to the connecting part 124 through the connecting arm 125 that is specifically connected to it.

[0070] When one connecting arm 125 corresponds to multiple supporting arms 121, the structure is more compact, reducing the number of connecting arms 125 and thus simplifying the overall structure of the support mechanism 12. When the weight of the poloidal field coil 2 acts on the supporting arm 121, multiple supporting arms 121 share the load and transmit the force to the connecting part 124 through the connecting arm 125.

[0071] The included angle between any two adjacent support arms 121 is the same specific angle. For example, this specific angle can be 30°, 45°, 60°, etc. A reasonable included angle allows the force borne by each support arm 121 to be more evenly distributed when the support mechanism 12 bears the weight of the poloidal field coil 2. When the poloidal field coil 2 is placed on the support mechanism 12, its weight is transmitted to the connecting part 124 through the support arms 121. If the included angles of adjacent support arms 121 are not uniform, some support arms 121 may be subjected to excessive force while others are subjected to less force, resulting in local stress concentration and affecting the service life and stability of the support mechanism 12. By optimizing the included angle, the force can be reasonably distributed among the support arms 121, improving the mechanical performance of the support mechanism 12.

[0072] According to some embodiments of the present invention, such as Figure 1-Figure 5 As shown, the moving mechanism 11 extends in the first direction, providing a basis for the movement of the transfer device 1, enabling it to move between different positions and meet the transfer requirements of the poloidal field coil 2 between different workstations.

[0073] The transfer device 1 also includes a transport bracket 161 and a lifting component 162. The transport bracket 161 extends in the first direction and is fixedly mounted on the moving mechanism 11, which facilitates a close connection between the transport bracket 161 and the moving mechanism 11, allowing them to move synchronously as the moving mechanism 11 moves. The transport bracket 161 serves to support and fix other components, providing a stable mounting platform for the lifting component 162 and the support mechanism 12.

[0074] The lifting components 162 are disposed on the transport bracket 161 and are configured as multiple units spaced apart from each other. The multiple lifting components 162 are distributed on the transport bracket 161, and the spacing can be reasonably adjusted according to the weight distribution and structural characteristics of the support mechanism 12 to ensure that the support mechanism 12 is provided with uniform and stable support force.

[0075] One end of the lifting component 162 is detachably connected to the transport bracket 161, and the other end of the lifting component 162 is detachably connected to the support mechanism 12, making the assembly and disassembly of the various components simple and quick, and providing convenient conditions for subsequent adjustment work. The lifting component 162 is suitable for lifting the support mechanism 12 at a preset height.

[0076] In actual poloidal field coil 2 transport scenarios, due to differences in size, weight, and installation requirements among different specifications of poloidal field coil 2, the required lifting height also varies. The preset height is determined by comprehensively considering factors such as the installation height of the poloidal field coil 2, space requirements during transport, and coordination with other equipment. By adjusting the height of the lifting component 162, the support mechanism 12 can be positioned appropriately, facilitating the loading, transport, and unloading of the poloidal field coil 2.

[0077] The main purpose of replacing the support component 162 with one of different sizes is to precisely adjust the lifting height of the poloidal coil 2. By selecting a suitable size support component 162, it can be ensured that the support mechanism 12 stably lifts the poloidal coil 2 to the preset height to meet the transportation and installation requirements under different working conditions.

[0078] When the lifting height needs to be adjusted according to the specifications of the poloidal field coil 2, the original lifting component 162 can be easily removed from the transport bracket 161 and the support mechanism 12. Then, according to the preset lifting height requirements, a new lifting component 162 of appropriate size is selected, and one end of it is installed on the transport bracket 161 and the other end is installed on the support mechanism 12.

[0079] The dimensions of the lifting component 162 directly determine the lifting height it can provide. Different sizes of lifting components 162 have different lengths, which will cause the spatial position of the support mechanism 12 to change after installation. By replacing the lifting component 162 with a different size, the relative distance between the support mechanism 12 and the transport bracket 161 is changed, thereby achieving precise adjustment of the lifting height of the poloidal field coil 2.

[0080] According to some embodiments of the present invention, such as Figures 3-5 As shown, the transfer device 1 also includes reinforcing members 163. Multiple reinforcing members 163 are configured, with at least two reinforcing members 163 correspondingly disposed on each lifting member 162 and spaced apart circumferentially from each lifting member 162. Therefore, each lifting member 162 is equipped with a certain number of reinforcing members 163 to enhance its structural performance, and these reinforcing members 163 are spaced apart circumferentially from each other. For example, if three reinforcing members 163 are correspondingly disposed on a lifting member 162, these three reinforcing members 163 will be evenly distributed around the lifting member 162, maintaining a certain angular interval between them.

[0081] Each reinforcing member 163 is connected at both ends to the supporting member 162 and the supporting mechanism 12, respectively, so that the reinforcing member 163 can tightly connect the supporting member 162 and the supporting mechanism 12 together to form a more stable overall structure. When the supporting member 162 bears the weight of the supporting mechanism 12 and the poloidal field coil 2, the reinforcing member 163 can share part of the load and transfer the force to the supporting mechanism 12, thereby reducing the stress on the supporting member 162 itself and improving the load-bearing capacity of the entire supporting structure.

[0082] The angles formed by any two reinforcing members 163 and the central axis of the connected supporting member 162 are equal. From a mechanical point of view, when multiple reinforcing members 163 are distributed around the supporting member 162 at equal angles, the multiple reinforcing members 163 can uniformly distribute the forces from the support mechanism 12 and the poloidal field coil 2. Assuming that the supporting member 162 is subjected to a vertically downward force, since the angles between the reinforcing members 163 and the central axis of the supporting member 162 are equal, the force component borne by each reinforcing member 163 is balanced in all directions. This avoids local stress concentration and reduces the risk of structural damage.

[0083] By incorporating multiple reinforcing members 163 and ensuring their proper distribution and connection, the connection strength between the lifting member 162 and the support mechanism 12 is enhanced. This allows the device to withstand greater loads when transporting heavy equipment like the poloidal field coil 2, which demands extremely high structural stability, thus ensuring a safe and reliable transport process.

[0084] According to some embodiments of the present invention, such as Figure 3 and Figure 5As shown, the support mechanism 12 has a first lifting hole 126. The first lifting hole 126 provides a connection point for the overall lifting of the support mechanism 12. By using a lifting tool through the first lifting hole 126, the support mechanism 12 can be lifted and transported to the designated installation location or working position.

[0085] According to some embodiments of the present invention, such as Figure 6 As shown, the support member 13 has a second lifting hole 137. When the support member 13 is installed at the designated position of the poloidal field coil 2, the second lifting hole 137 provides a connection point for the lifting equipment. Lifting the support member 13, and subsequently the poloidal field coil 2, using the lifting equipment improves the efficiency and accuracy of the installation.

[0086] According to some embodiments of the present invention, such as Figure 8 As shown, the mobile mechanism 11 includes a power unit 111, a six-axle module transport vehicle 112, and two four-axle module transport vehicles 113. The power unit 111, the six-axle module transport vehicle 112, and the two four-axle module transport vehicles 113 are arranged along a first direction and connected in sequence.

[0087] The power unit 111 can be a PPU power unit 111. A PPU power unit 111 (usually referring to a Power Pack Unit Locomotive or Powered Pusher Unit) is a power unit that can work independently or in conjunction with others to drive heavy loads on rails, flat ground, or specific routes by providing strong traction or thrust.

[0088] The six-axle modular transport vehicle 112 and the four-axle modular transport vehicle 113 are two types of specialized engineering vehicles used for transporting ultra-heavy and large-sized goods. The six-axle modular transport vehicle 112 features independent all-wheel steering, supporting lateral translation, on-the-spot rotation, and serpentine movement, with a small minimum turning radius. The four-axle modular transport vehicle 113 has lower steering flexibility (typically front-axle steering or limited all-wheel steering), and a larger minimum turning radius. Each wheel of the power unit 111, the six-axle modular transport vehicle 112, and the four-axle modular transport vehicle 113 is hydraulically height-adjustable, with a hydraulic adjustment compensation stroke of 700mm (i.e., adjustable within ±350mm). By adjusting the hydraulic compensation height of each axle tire, the transport vehicle can achieve level transport on inclined surfaces and on the platform.

[0089] In the above technical solution, the mobile mechanism 11 includes a power unit 111, a six-axle modular transport vehicle 112, and two four-axle modular transport vehicles 113 (total weight 60t during transport). By increasing the ground bearing area, it ensures that the load-bearing capacity of the pre-assembly hall floor is met when transporting the vehicle to the pre-assembly hall. The power unit 111, as the main drive unit, provides high torque output and intelligent speed regulation (such as frequency conversion control), ensuring smooth start / braking, avoiding load shifting due to inertial impact, and improving the reliability of the transport device 1. The six-axle modular transport vehicle 112 and the four-axle modular transport vehicle 113 can adjust the hydraulic compensation height of each axle tire to achieve horizontal transport on inclined surfaces and ensure installation accuracy, thus improving the reliability of the transport device 1. At the same time, the connection between the six-axle modular transport vehicle 112 and the power unit 111 allows for flexible turning, improving the versatility of the transport device 1.

[0090] The following is for reference. Figure 9 A brief description of the transfer method according to the present invention.

[0091] like Figure 9 As shown, the transfer method according to the present invention is used in the transfer device 1 of any of the above embodiments. The transfer method includes: measuring the size of the poloidal field coil 2, and installing a plurality of adapted support members 13 on the poloidal field coil 2 according to the size measurement results; hoisting the poloidal field coil 2 equipped with support members 13 onto the support mechanism 12 and cooperating each support member 13 with the corresponding limiting member 14; measuring the position of the poloidal field coil 2, and adjusting the position of the poloidal field coil 2 by a plurality of adjusting members 15 according to the position measurement results; and activating the moving mechanism 11 to transfer the poloidal field coil 2 to a designated location.

[0092] According to the transfer method of the present invention, firstly, the dimensions of the poloidal field coil 2 are measured, and multiple compatible support members 13 are installed on the poloidal field coil 2 based on the measurement results. Using professional measuring tools, such as a laser rangefinder, the key dimensions of the poloidal field coil 2, such as length, width, height, and diameter, are measured. Based on the measured dimensional data, compatible support members 13 are selected from a variety of pre-prepared specifications, and multiple support members 13 are securely installed on the poloidal field coil 2 according to a predetermined installation position and method. The support members 13 can also be modular, meaning they can be quickly assembled on-site from multiple modular components according to actual needs, allowing for flexible adjustment of size and structure. Since different specifications of poloidal field coils 2 have different dimensions, the compatible support members 13 can provide uniform and stable support force to the poloidal field coil 2, ensuring that the poloidal field coil 2 will not deform or be damaged due to uneven force during subsequent hoisting and transfer, thus guaranteeing the integrity and performance of the poloidal field coil 2.

[0093] Then, the poloidal coil 2, equipped with support members 13, is hoisted onto the support mechanism 12, with each support member 13 engaging with its corresponding limiting member 14. Using hoisting equipment, the poloidal coil 2, with its support members 13 installed, is slowly and smoothly lifted and accurately placed onto the support mechanism 12 of the transfer device 1. During placement, it is essential to ensure that each support member 13 precisely engages with its corresponding limiting member 14 on the support mechanism 12, ensuring that the poloidal coil 2 is accurately positioned and securely fixed on the support mechanism 12. The support mechanism 12 provides a stable bearing platform for the poloidal coil 2, while the engagement of the limiting member 14 with the support member 13 serves to position and fix the coil, preventing displacement during transfer and ensuring the safety and stability of the transfer process.

[0094] Next, the position of the poloidal coil 2 is measured, and its position is adjusted using multiple adjusting components 15 based on the measurement results. Using measuring instruments, the position of the poloidal coil 2 on the support mechanism 12 is precisely measured, including but not limited to parameters such as the center position, horizontality, and verticality of the poloidal coil 2. Based on the measurement results, the position of the poloidal coil 2 is adjusted by operating the multiple adjusting components 15 on the support mechanism 12 to achieve the preset precise position. By adjusting the position of the poloidal coil 2, it is ensured that after being transported to the designated location, the poloidal coil 2 can be accurately docked and installed with other equipment or components, improving the assembly accuracy and quality of the entire nuclear fusion device.

[0095] Finally, the moving mechanism 11 is activated to transport the poloidal field coil 2 to the designated location. After confirming that the position of the poloidal field coil 2 is accurately adjusted and securely fixed, the moving mechanism 11 of the transport device 1 is activated, and the poloidal field coil 2 is smoothly transported to the designated installation location according to the predetermined route and speed. This completes the final transport task of the poloidal field coil 2, bringing it to the required position and preparing it for subsequent installation, commissioning, or use.

[0096] According to the transfer method of the present invention, by measuring dimensions and installing the appropriate support 13, and by cooperating with the limiting component 14, displacement of the poloidal field coil 2 during transfer can be effectively prevented, ensuring the safety of operators and equipment. Through position measurement and adjustment steps, the positional accuracy of the poloidal field coil 2 before and after transfer can be ensured, meeting the stringent requirements of nuclear fusion devices for component installation accuracy, and improving the assembly quality and operational stability of the entire device. The transfer method is applicable to poloidal field coils 2 of different specifications. By selecting the appropriate support 13 and making corresponding position adjustments according to the dimensions of the poloidal field coil 2, it has strong versatility and adaptability, meeting diverse needs. The entire transfer process is carried out in an orderly manner according to clear steps, with a standardized and concise operation process, reducing unnecessary operational steps and time waste, improving transfer efficiency, and reducing production costs.
