[0024] The PF5 coil has unique and demanding characteristics. Its overall dimensions are enormous, reaching Φ10.8×3m, and its weight is as high as approximately 147 tons. During transportation, to ensure the safety and stable performance of the PF5 coil, the transportation speed must be strictly controlled to less than 1km / h. Furthermore, the installation accuracy requirements for superconducting joints are extremely high, with the error controlled within ±0.5mm, and the dynamic load coefficient and eccentric load coefficient both being 1.0. However, the transfer tooling and methods used in the related art struggle to meet such stringent requirements.

[0025] Reference below Figures 1-8 A transfer device 1 according to an embodiment of the present invention will be described.

[0026] like Figure 1-Figure 7 As shown, a transfer device 1 according to the present invention is used to transport 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 is used to provide mobility for the transfer device 1, enabling the transfer device 1 to carry the poloidal field coil 2 between different locations. The moving mechanism 11 needs to have stable mobility and be able to adapt to different road conditions. The moving speed can be adjusted according to actual needs to meet the strict speed requirements during the transportation of the poloidal field coil 2.

[0027] The support mechanism 12 is fixed to the mobile mechanism 11 and includes a plurality of radially extending support arms 121 spaced circumferentially. These arms 121 provide a fixed position and extension direction for the subsequent installation of the support member 13. They support the poloidal field coil 2 from multiple directions, ensuring its stability during transport. The circumferential spacing evenly distributes the weight of the poloidal field coil 2, while the radial extension facilitates adjustment and support based on the size and shape of the poloidal field coil 2.

[0028] The support members 13 are constructed to correspond one to one with the support arms 121, that is, each support arm 121 is mounted with a support member 13. Each support member 13 is movably arranged in the extension direction of the support arm 121. Therefore, 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, so that the support member 13 can 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 on the support member 13 to prevent the poloidal field coil 2 from shaking or shifting during transportation.

[0029] The limiting members 14 are constructed to correspond one to one with the support arms 121, that is, each support arm 121 is provided with a limiting member 14. Each limiting member 14 is provided on the support arm 121 to provide a fixed point for subsequent connection and adjustment with the support member 13. The limiting member 14 is connected to the support member 13 by an adjusting member 15, and the adjusting member 15 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, the multiple supporting members 13 can be respectively clamped at multiple positions in the circumferential direction of the poloidal field coil 2. The position of each supporting member 13 can be adjusted according to the actual size of the poloidal field coil 2 to ensure that the poloidal field coil 2 is subjected to uniform and appropriate support force in the circumferential direction, thereby further ensuring the stability and safety of the poloidal field coil 2 during transportation.

[0030] By adjusting the position of the support member 13 through the adjusting member 15 , the poloidal field coil 2 can maintain an accurate posture during transportation, thereby avoiding a decrease in installation accuracy due to shaking or displacement.

[0031] Therefore, the transfer device 1 according to the present invention can meet the transfer requirements of the poloidal field coil 2 that is large in size, heavy in weight, and has stringent requirements, and ensure that the poloidal field coil 2 is accurately positioned and reasonably stressed during the transfer process, meeting the requirements of the dynamic load coefficient and the eccentric load coefficient.

[0032] According to some embodiments of the present invention, Figure 5-Figure 7 As shown, each limit member 14 is arranged on at least one side of the corresponding support arm 121 in the radial direction and extends in the height direction. Therefore, the limit 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 limit member 14 can provide stable fixing and guiding effects in the radial direction for subsequent adjustment and support.

[0033] Each adjusting member 15 extends in the radial direction, that is, the length direction of the adjusting member 15 is consistent with the radial direction of the support mechanism 12. And each adjusting member 15 end is provided with an adjusting block 151 suitable for being fitted with the surface of the support member 13. The adjusting block 151 is used to increase the contact area between the adjusting member 15 and the support member 13, so that the force during the adjustment process is more uniform and stable, thereby improving the adjustment accuracy. The adjusting member 15 is movably connected to the corresponding limiting member 14. The movable connection method can be a threaded connection, a slide rail connection, etc. Through the movably connected, the adjusting member 15 can move under the constraint of the limiting member 14, thereby realizing the adjustment of the radial position of the adjusting block 151.

[0034] When the radial position of the support member 13 needs to be adjusted, the adjustment member 15 is operated. Since the adjustment member 15 is movably connected to the limit member 14, the adjustment member 15 will move radially under the guidance of the limit member 14. The adjustment block 151 at the end of the adjustment member 15 is in contact with the surface of the support member 13. As the adjustment member 15 moves, the adjustment block 151 pushes 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 requirements such as the dynamic load coefficient and the eccentric load coefficient.

[0035] For example, if the adjusting member 15 is threadedly connected to the corresponding limiting member 14, the adjusting member 15 is provided with an external thread and the limiting member 14 is provided with a corresponding internal threaded hole, then by rotating the adjusting member 15, the adjusting member 15 can be moved radially in the limiting member 14, thereby driving the adjustment block 151 to move. It should be noted that the above exemplary description is merely to facilitate understanding of a 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 between the two.

[0036] According to some embodiments of the present invention, Figure 6 As shown, the adjusting member 15 is constructed as a plurality of adjusting members 15 spaced apart in the height direction, and can adjust the supporting member 13 at different height levels, so that the supporting 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.

[0037] According to some embodiments of the present invention, Figure 6As shown, each support member 13 comprises a base plate 131, a clamping plate 132, and a top plate 133. Base plate 131 is movable in the direction of extension of support arm 121, enabling base plate 131 to drive the entire support member 13 to move radially along support arm 121. By moving base plate 131, the position of support member 13 is adjusted, enabling the poloidal field coil 2 to maintain its accurate position during transport, preventing loss of installation accuracy due to shaking or displacement.

[0038] The clamping plates 132 are removably mounted on the base plate 131, facilitating their replacement. By replacing clamping plates 132 of varying sizes, the size of the clamping cavity 134 can be adjusted to accommodate poloidal field coils 2 of varying sizes. The clamping plates 132 are constructed as two radially spaced plates. These clamping plates 132 can clamp the poloidal field coil 2 from either side, providing a stable and uniform clamping force. This prevents radial movement or shaking of the poloidal field coil 2, ensuring stability during transport and installation.

[0039] The top plate 133 is disposed on the two clamping plates 132 and is parallel to and spaced apart from the bottom plate 131 in the height direction. A clamping cavity 134 is defined between the top plate 133, the bottom plate 131, and the two clamping plates 132. The poloidal field coil 2 can be placed within the clamping cavity 134. The top plate 133 and the bottom plate 131 are connected by an adjustment rod 135, which is suitable for adjusting 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 via the adjustment rod 135, the clamping plates 132 of different sizes can be replaced to accommodate the actual height of the poloidal field coil 2. This allows the bottom plate 131, the top plate 133, and the clamping plates 132 to more closely fit the poloidal field coil 2, thereby jointly applying an appropriate clamping force to the object, restricting the movement of the poloidal field coil 2, and further improving the stability and reliability of the clamping.

[0040] According to some embodiments of the present invention, Figure 6 As shown, the inner surface of the clamping plate 132 facing the clamping cavity 134 is provided with an isolation layer 136, which is suitable for contacting the poloidal field coil 2. By providing the isolation layer 136, the isolation layer 136 can protect the poloidal field coil 2 and achieve the structural integrity of the poloidal field coil 2.

[0041] Isolation layer 136 possesses a certain degree of flexibility and elasticity, allowing it to adhere tightly to the surface of poloidal field coil 2, forming a uniform protective layer. When subjected to external impact during transportation, isolation layer 136 elastically deforms, absorbing and dissipating some of the impact energy, providing a cushioning and shock-absorbing effect. This protects the structural integrity of poloidal field coil 2 and prevents the insulation layer of poloidal field coil 2 from being damaged during transportation.

[0042] The isolation layer 136 has a low friction coefficient. During transportation, when there is a slight relative movement or vibration between the poloidal field coil 2 and the clamping plate 132 , the friction between the two can be reduced, thereby reducing the risk of wear on the surface of the poloidal field coil 2 .

[0043] Illustratively, isolation layer 136 is constructed as a polytetrafluoroethylene layer. Polytetrafluoroethylene layers have excellent chemical stability, a low coefficient of friction, and good flexibility and elasticity, meeting the requirements for isolation layer 136. It should be noted that the above exemplary description is merely intended to facilitate understanding of the preferred embodiment of isolation layer 136 in the present invention and is not intended to limit the present invention. In actual applications, isolation layer 136 may also be made of other materials with similar properties, as long as they meet the requirements of protecting poloidal field coil 2, providing a cushioning and shock-absorbing effect, and reducing the coefficient of friction.

[0044] According to some embodiments of the present invention, 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 provided, each connected between the ends of multiple adjacent support arms 121. The outer ring beams 122 bring together and secure the ends of multiple support arms 121, forming a single, integral connection node. For example, if there are 12 support arms 121, the outer ring beams 122 may connect the ends of three or four adjacent support arms 121. The specific number of connections depends on the design layout and force requirements.

[0045] Multiple inner ring beams 123 are configured to correspond one-to-one with the outer ring beams 122. Each inner ring beam 123 is arranged parallel to the corresponding outer ring beam 122 and connects between the other ends of multiple adjacent support arms 121. In other words, the inner ring beams 123 converge and secure the other ends of the support arms 121, complementing the outer ring beams 122 to securely connect the two ends of the support arms 121. For example, an inner ring beam 123 corresponding to an outer ring beam 122 connecting one end of three support arms 121 will also connect the other ends of those three support arms 121.

[0046] The outer ring beam 122 and the inner ring beam 123 are connected to the support arm 121 to form a ring-like stable support frame, which provides an all-round support foundation for the poloidal field coil 2 and can withstand the weight of the poloidal field coil 2 and various external forces generated during transportation. When the poloidal field coil 2 is placed on the support structure composed of the support arm 121, the outer ring beam 122 and the inner ring beam 123, its weight will be evenly distributed to the outer ring beam 122 and the inner ring beam 123 through the support arm 121. The outer ring beam 122 and the inner ring beam 123 then transfer this part of the force to the mobile mechanism 11, which can better resist the force during transportation, ensure that the support mechanism 12 can remain stable under various working conditions, and provide reliable support for the poloidal field coil 2.

[0047] According to some embodiments of the present invention, Figure 7 As shown, multiple support arms 121 are arranged in a centrally symmetrical distribution, ensuring that the support structure has consistent geometric 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. Because a complete circle has a 360° angle, when there are n support arms 121 evenly distributed around the circle, the formula for calculating the central angle is obtained by evenly distributing 360° between every two adjacent support arms 121.

[0048] If the number of support arms 121 n=12, then the central angle between any two adjacent support arms 121 is 360° ÷ 12 = 30°. Therefore, the angle between every two adjacent support arms 121 on the circumference around the center point is 30°, and the 12 support arms 121 evenly divide the entire circumference into 12 equal parts.

[0049] When transporting the poloidal field coil 2, the weight of the poloidal field coil 2 and various external forces generated during transport will act on the support arms 121. Since the support arms 121 are centrally symmetrically distributed and the central angles between adjacent support arms 121 are fixed, the forces can be evenly distributed to each support arm 121.

[0050] After clarifying the actual size of the poloidal field coil 2 and the distribution characteristics of the support arm 121, the distance between the support member 13 and the limit member 14 can be adjusted with the help of the adjustment 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 to ensure that the support member 13 can reach the appropriate support point. The support point is calculated and designed so that the support member 13 can achieve a stable fit with the outer surface of the poloidal field coil 2, providing a uniform and stable support force for the poloidal field coil 2. In this way, no matter what the size of the poloidal field coil 2 is, it can be reliably and effectively supported during the transportation process, ensuring the smooth progress of the transportation work and the accuracy and quality of the subsequent installation of the nuclear fusion device.

[0051] According to some embodiments of the present invention, Figure 7 As shown, the support mechanism 12 is further formed with a connecting portion 124. The connecting portion 124 is arranged at the symmetrical center of the multiple support arms 121, so that the support mechanism 12 is more balanced in terms of mechanical distribution. The connecting portion 124 extends radially into multiple connecting arms 125, each connecting arm 125 being connected to the other end of a support arm 121, thereby tightly connecting the connecting portion 124 to the multiple support arms 121. The number of connecting arms 125 corresponds to the number of support arms 121, and the corresponding relationship can be one-to-one or one connecting arm 125 can correspond to multiple support arms 121.

[0052] When one connecting arm 125 corresponds to one supporting arm 121 , the load from the poloidal field coil 2 borne by each supporting arm 121 can be accurately and independently transferred to the connecting portion 124 through the connecting arm 125 exclusively connected thereto.

[0053] When one connecting arm 125 corresponds to multiple support arms 121, the structure is more compact, the number of connecting arms 125 can be reduced, and the overall structure of the support mechanism 12 is simplified. When the weight of the poloidal field coil 2 acts on the support arms 121, the multiple support arms 121 share the load and transmit the force to the connecting portion 124 through the connecting arms 125.

[0054] The angle formed between any two adjacent support arms 121 is the same specific angle. For example, the specific angle can be 30°, 45°, 60°, etc. A reasonable angle can make the force borne by each support arm 121 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 will be transferred to the connecting portion 124 through the support arm 121. If the angles between adjacent support arms 121 are not uniform, some support arms 121 may be subjected to excessive force while other support arms 121 are subjected to less force, thereby causing local stress concentration and affecting the service life and stability of the support mechanism 12. By optimizing the size of the angle, the force can be reasonably distributed among the support arms 121, thereby improving the mechanical properties of the support mechanism 12.

[0055] According to some embodiments of the present invention, Figure 1-Figure 5 As shown, the moving mechanism 11 extends in a first direction, providing a basis for movement of the transfer device 1, enabling it to move between different positions, thereby meeting the transfer requirements of the poloidal field coil 2 between different workstations.

[0056] The transfer device 1 further includes a transport bracket 161 and a lifting member 162. The transport bracket 161 extends in a first direction and is fixedly mounted on the mobile mechanism 11. This facilitates close connection between the transport bracket 161 and the mobile mechanism 11, allowing the transport bracket 161 to move synchronously with the movement of the mobile mechanism 11. The transport bracket 161 serves to support and secure other components, providing a stable mounting platform for the lifting member 162 and the support mechanism 12.

[0057] The lifting members 162 are arranged on the transport bracket 161 and are constructed to be multiple and spaced apart from each other. The multiple lifting members 162 are distributed on the transport bracket 161. The spacing setting 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.

[0058] One end of the lifting member 162 is detachably connected to the transport bracket 161, and the other end of the lifting member 162 is detachably connected to the support mechanism 12, making assembly and disassembly between the various components simple and quick, and providing convenient conditions for subsequent adjustment work. The lifting member 162 is suitable for lifting the support mechanism 12 at a preset height.

[0059] In actual poloidal field coil 2 transport scenarios, the required lifting height varies due to differences in size, weight, and installation requirements for different poloidal field coils 2. The preset height is determined based on a comprehensive consideration of factors such as the installation height of the poloidal field coil 2, the space required during transport, and coordination with other equipment. By adjusting the height of the lifting member 162, the support mechanism 12 can be positioned appropriately, facilitating the loading, transport, and unloading of the poloidal field coil 2.

[0060] The purpose of replacing the lifting members 162 with different sizes is to precisely adjust the lifting height of the poloidal field coil 2. By selecting the lifting members 162 of the appropriate size, it is possible to ensure that the support mechanism 12 stably lifts the poloidal field coil 2 to a preset height to meet the transportation and installation requirements under different working conditions.

[0061] When the lifting height needs to be adjusted according to the specifications of the poloidal field coil 2, the original lifting piece 162 can be easily removed from the transport bracket 161 and the support mechanism 12. Then, according to the preset lifting height requirement, a new lifting piece 162 of appropriate size is selected and one end of the new lifting piece 162 is installed on the transport bracket 161 and the other end is installed on the support mechanism 12.

[0062] The size of the lifting member 162 directly determines the lifting height it can provide. The length differences between lifting members 162 of different sizes can cause the spatial position of the support mechanism 12 to change after installation. By replacing lifting members 162 of different sizes, 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.

[0063] According to some embodiments of the present invention, Figure 3-Figure 5 As shown, the transfer device 1 further includes a plurality of reinforcement members 163, with at least two reinforcement members 163 correspondingly provided on each supporting member 162 and spaced apart circumferentially around the corresponding supporting member 162. Therefore, each supporting member 162 is equipped with a certain number of reinforcement members 163 to enhance its structural performance, and these reinforcement members 163 are spaced apart circumferentially around the corresponding supporting member 162. For example, if three reinforcement members 163 are provided on a supporting member 162, these three reinforcement members 163 are evenly distributed around the supporting member 162, maintaining a certain angular spacing between them.

[0064] Each reinforcement member 163 has two ends connected to the support member 162 and the support mechanism 12, respectively. This allows the reinforcement members 163 to tightly connect the support member 162 and the support mechanism 12, forming a more stable overall structure. When the support member 162 bears the weight of the support mechanism 12 and the poloidal field coil 2, the reinforcement members 163 can share some of the load, transferring the force to the support mechanism 12, thereby reducing the load on the support member 162 itself and improving the load-bearing capacity of the entire support structure.

[0065] The angles formed between any two reinforcement members 163 and the central axis of the connected support member 162 are equal. From a mechanical perspective, when multiple reinforcement members 163 are distributed around the support member 162 at equal angles, they can evenly disperse the forces from the support mechanism 12 and the poloidal field coil 2. Assuming that the support member 162 is subjected to a vertical downward force, because the angles between the reinforcement members 163 and the central axis of the support member 162 are equal, the force components borne by each reinforcement member 163 are balanced in all directions, thus avoiding local stress concentration and reducing the risk of structural damage.

[0066] By providing multiple reinforcement members 163 and rationally distributing and connecting them, the connection strength between the lifting member 162 and the support mechanism 12 is enhanced. When transporting equipment such as the poloidal field coil 2, which is heavy and requires extremely high structural stability, it can withstand a greater load, ensuring the safety and reliability of the transportation process.

[0067] According to some embodiments of the present invention, Figure 3 and Figure 5As shown, the support mechanism 12 is formed with a first hoisting hole 126. The first hoisting hole 126 provides a connection point for the entire hoisting of the support mechanism 12. By using a hoisting tool through the first hoisting hole 126, the support mechanism 12 can be hoisted and transported to a designated installation site or work location.

[0068] According to some embodiments of the present invention, Figure 6 As shown, support member 13 is formed with a second lifting hole 137. When support member 13 is installed at a designated location on poloidal field coil 2, second lifting hole 137 provides a connection point for lifting equipment. Using the lifting equipment to lift support member 13, and thereby lift poloidal field coil 2, improves installation efficiency and accuracy.

[0069] According to some embodiments of the present invention, Figure 8 As shown, the moving mechanism 11 includes a power locomotive 111, a six-axis module transporter 112 and two four-axis module transporters 113. The power locomotive 111, the six-axis module transporter 112 and the two four-axis module transporters 113 are arranged along a first direction and connected in sequence.

[0070] The power locomotive 111 may be a PPU power locomotive 111. The PPU power locomotive 111 (usually referred to as a Power Pack Unit Locomotive or Powered Pusher Unit) is a power unit that can work independently or collaboratively, and drives heavy loads to move on tracks, flat ground or specific routes by providing strong traction or thrust.

[0071] The six-axle modular transporter 112 and the four-axle modular transporter 113 are two special engineering vehicles used for transporting super-heavy and large-sized cargo. The six-axle modular transporter 112 has independent steering on all wheels, supports lateral translation, rotation on the spot, and serpentine movement, and has a small minimum turning radius. The four-axle modular transporter 113 has lower steering flexibility (usually front-axle steering or limited all-wheel steering) and a large minimum turning radius. Among them, each wheel of the power locomotive 111, the six-axle modular transporter 112, and the four-axle modular transporter 113 can be hydraulically height-adjustable, and the compensation stroke of the hydraulic adjustment is 700mm (i.e., adjustable within the range of ±350mm). By adjusting the hydraulic compensation height of the tires of each axle, the transport vehicle can be transported on an inclined surface with the vehicle plate surface level.

[0072] In the above technical solution, the mobile mechanism 11 comprises a power locomotive 111, a six-axle module transporter 112, and two four-axle module transporters 113 (total weight 60t during transfer). This increases the ground-bearing area to ensure that the load-bearing capacity of the pre-installation hall floor is met during transfer to the pre-installation hall. The power locomotive 111, serving as the main drive unit, provides high torque output and intelligent speed regulation (e.g., variable frequency control), ensuring smooth starting and braking, avoiding load shifting due to inertial shock, and improving the reliability of the transfer mechanism 1. The six-axle module transporter 112 and the four-axle module transporter 113 can adjust the hydraulic compensation height of the tires on each axle to enable the mobile mechanism 11 to transport on inclined surfaces and maintain a level vehicle surface, ensuring installation accuracy and improving the reliability of the transfer mechanism 1. Furthermore, the six-axle module transporter 112, connected to the power locomotive 111, enables flexible turning, enhancing the versatility of the transfer mechanism 1.

[0073] Reference below Figure 9 The transporting method according to the present invention is briefly described.

[0074] like Figure 9 As shown, the transport method according to the present invention is used for the transport device 1 in any of the above-mentioned embodiments. The transport method includes: measuring the dimensions of the poloidal field coil 2, and installing a plurality of adapted supports 13 on the poloidal field coil 2 based on the dimension measurement results; hoisting the poloidal field coil 2 equipped with the supports 13 onto the support mechanism 12, and ensuring that each support 13 is engaged with a corresponding limiter 14; measuring the position of the poloidal field coil 2, and adjusting the position of the poloidal field coil 2 using a plurality of adjusters 15 based on the position measurement results; and activating the moving mechanism 11 to transport the poloidal field coil 2 to a designated location.

[0075] According to the transport method of the present invention, the poloidal field coil 2 is first dimensionally measured, and multiple matching supports 13 are installed on the poloidal field coil 2 based on the dimensional measurement results. Professional measuring tools, such as a laser rangefinder, are used to measure key dimensions of the poloidal field coil 2, such as length, width, height, and diameter. Based on the measured dimensional data, matching supports 13 are selected from a variety of pre-prepared specifications, and the multiple supports 13 are securely installed on the poloidal field coil 2 according to predetermined installation positions and methods. The supports 13 can also be prefabricated, that is, composed of multiple modular components that can be quickly assembled on-site according to actual needs, allowing for flexible adjustment of size and structure. Due to the dimensional differences between poloidal field coils 2 of different specifications, the matching supports 13 can provide uniform and stable support for the poloidal field coil 2, ensuring that the poloidal field coil 2 will not be deformed or damaged due to uneven force during subsequent lifting and transport, thereby safeguarding the integrity and performance of the poloidal field coil 2.

[0076] Then, the poloidal field coil 2 equipped with the support members 13 is hoisted onto the support mechanism 12 and each support member 13 is matched with the corresponding limit member 14. Using the hoisting equipment, the poloidal field coil 2 with the support members 13 installed is slowly and steadily lifted and accurately placed on the support mechanism 12 of the transfer device 1. During the placement process, it is necessary to ensure that each support member 13 can accurately match the corresponding limit member 14 on the support mechanism 12, so that the poloidal field coil 2 is accurately positioned and firmly fixed on the support mechanism 12. The support mechanism 12 provides a stable bearing platform for the poloidal field coil 2, and the matching of the limit member 14 and the support member 13 plays a role in positioning and fixing, preventing the poloidal field coil 2 from shifting during the transfer process, thereby ensuring the safety and stability of the transfer process.

[0077] Next, the position of the poloidal field coil 2 is measured, and the position of the poloidal field coil 2 is adjusted using multiple adjustment members 15 based on the position measurement results. Using a measuring instrument, the position of the poloidal field coil 2 on the support mechanism 12 is accurately measured, including but not limited to parameters such as the center position, horizontality, and verticality of the poloidal field coil 2. Based on the measurement results, the position of the poloidal field coil 2 is adjusted by operating the multiple adjustment members 15 on the support mechanism 12 to achieve a preset precise position. By adjusting the position of the poloidal field coil 2, it is ensured that the poloidal field coil 2 can be accurately docked and installed with other equipment or components after being transported to the designated location, thereby improving the assembly accuracy and quality of the entire nuclear fusion device.

[0078] Finally, the moving mechanism 11 is activated to transport the poloidal field coil 2 to the designated location. After confirming that the poloidal field coil 2 is accurately positioned and securely fixed, the moving mechanism 11 of the transport device 1 is activated to smoothly transport the poloidal field coil 2 to the designated installation location along the predetermined route and speed. This completes the final transport of the poloidal field coil 2, ensuring that it reaches the desired location and is ready for subsequent installation, commissioning, or use.

[0079] According to the transport method of the present invention, by measuring the size and installing the matching support member 13, as well as cooperating with the limit member 14, the displacement of the poloidal field coil 2 during transport can be effectively prevented, thereby ensuring the safety of the operator and the equipment. Through the position measurement and adjustment steps, the position accuracy of the poloidal field coil 2 before and after transport can be ensured, meeting the strict requirements of the nuclear fusion device on the installation accuracy of components, and improving the assembly quality and operational stability of the entire device. The transport method is applicable to poloidal field coils 2 of different specifications. By selecting the matching support member 13 according to the size of the poloidal field coil 2 and making corresponding position adjustments, it has strong versatility and adaptability and can meet diverse needs. The entire transport process is carried out in an orderly manner according to clear steps, and the operating process is standardized and concise, which reduces unnecessary operating links and time waste, improves transport efficiency, and reduces production costs.
