Description

Technical Field

[0001] This invention relates to the field of tokamak nuclear fusion technology, and in particular to a support device and a feeding device for pre-assembled components of a nuclear fusion device. Background Technology

[0002] A tokamak, a device for controlled nuclear fusion, primarily utilizes magnetic confinement to control high-temperature plasma, causing a fusion reaction within a vacuum chamber to release enormous energy, which is then converted for human use. At the center of the tokamak is a large, annular pressure vessel. Due to its unique annular structure, the tokamak device needs to be divided evenly along its circumference to ensure each sector is relatively independent. During assembly, each tokamak sector includes a vacuum chamber, a vacuum chamber cold shield, and a TF magnet (superconducting magnet). For ease of explanation, this assembly of the vacuum chamber, cold shield, and TF magnet in each sector can be referred to as a pre-assembled component. Because the vacuum chamber and TF magnet in each pre-assembled component are quite heavy (>50t), their center of gravity needs to be lowered and they need to be moved horizontally during transportation. Furthermore, during overall assembly, the component's orientation needs to be adjusted to a vertical position. Therefore, during on-site installation, the orientation needs to be adjusted from horizontal to vertical. During the overall attitude adjustment process, the center of gravity height of the pre-assembled components will change significantly, and the direction of the force on the support will also change. Therefore, how to meet the positional accuracy of heavy and large pre-assembled components during the attitude adjustment process has become one of the urgent problems to be solved. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a support device for pre-assembled components of a nuclear fusion device, which can provide rigid support for the pre-assembled components from a horizontal state to a vertical state, effectively avoiding relative slippage of the pre-assembled components during changes in attitude and center of gravity, and improving the positional accuracy of the pre-assembled components.

[0041] The support device 100 for the pre-assembled components of the nuclear fusion device in this embodiment of the invention can be used for the pre-assembled components 300. The nuclear fusion device may include multiple pre-assembled components 300, which are sequentially assembled into a ring along the circumference. The pre-assembled components 300 are generally fan-shaped and may include a vacuum chamber, a vacuum chamber cold shield, and a TF magnet. The composition and operation of the nuclear fusion device are known to those skilled in the art and will not be described in detail here. In addition, the support device 100 for the pre-assembled components of the nuclear fusion device can also be applied to other heavy-duty components and similar scenarios.

[0042] The following is for reference. Figures 1-6 This describes a support device 100 for pre-assembled components of a nuclear fusion device according to an embodiment of the present invention.

[0043] like Figures 1 to 3 As shown, the support device 100 for the pre-assembled components of the nuclear fusion device according to an embodiment of the present invention includes: a base 10, a first support mechanism 20, and a second support mechanism 30. The first support mechanism 20 supports the pre-assembled component 300 along a first direction and is connected to the base 10; the second support mechanism 30 supports the pre-assembled component 300 along a second direction, which is perpendicular to the first direction. The second support mechanism 30 includes a support base 31, a hydraulic lifting component 32, a support rod 33, and a locking nut 34. The support base 31 is connected to the base 10 through the hydraulic lifting component 32 and the support rod 33. Multiple support rods 33 are arranged around the circumference of the hydraulic lifting component 32. Each support rod 33 is guided and engaged with the base 10 along the second direction and is provided with a threaded portion 331. Multiple locking nuts 34 are installed on the threaded portion 331. The locking nuts 34 and the threaded portion 331 cooperate to lock the support rod 33 relative to the base 10 in the second direction.

[0044] The base 10 can refer to a component that provides an installation foundation for the first support mechanism 20 and the second support mechanism 30, and can be made of high-strength materials such as alloy steel, stainless steel, and composite materials, but is not limited to. The base 10 can be, but is not limited to, a frame structure, a column structure, or a composite structure composed of a frame structure and a column structure, etc.

[0045] The first support mechanism 20 can refer to a mechanism that supports the pre-assembled component 300 along a first direction and connects to the base 10. The first support mechanism 20 can be, but is not limited to, a frame structure, a plate structure, or a beam structure, etc. For example, see [reference needed]. Figure 1 The first support structure 20 can be a support beam. The first direction can be referenced... Figure 1 The left and right directions, combined with Figure 4 The first direction is Figure 4 In the vertical direction, that is, when the pre-assembled component 300 is in a horizontal state, the first support mechanism 20 can support the support device 100 of the entire nuclear fusion device pre-assembled component in the vertical direction.

[0046] The second support mechanism 30 can refer to a mechanism that supports the pre-assembled component 300 along a second direction. (See reference) Figure 1 The second direction can be Figure 1 The up and down directions, combined with Figure 4 The second direction can be Figure 4 The left and right directions.

[0047] In the above technical solution, the second support mechanism 30 includes a support base 31, a hydraulic lifting component 32, a support rod 33, and a locking nut 34. The support base 31 can refer to the component in the second support mechanism 30 that contacts the pre-assembled assembly 300, and can be, but is not limited to, a frame structure, plate structure, or beam structure, etc. The hydraulic lifting component 32 can refer to the component that controls the lifting of the support base 31, and can be, but is not limited to, a hydraulic cylinder and a hydraulic rod, etc. The support rod 33 can refer to the component that supports the support base 31, and multiple support rods are provided around the circumference of the hydraulic lifting component 32. Each support rod 33 is guided and engaged with the base 10 in a second direction, and can follow the lifting of the hydraulic lifting component 32 to support the support base 31. The support rod 33 is provided with a threaded portion 331, and multiple locking nuts 34 are installed on the threaded portion 331. The locking nuts 34 and the threaded portion 331 cooperate to lock the support rod 33 relative to the base 10 in the second direction, which can limit the displacement of the base 10 in the second direction. For example, when the pre-assembled assembly 300 changes from a horizontal state (see...), the support rod 33 can be locked relative to the base 10 in the second direction. Figure 4 Adjust to a vertical position (see) Figure 6 When the locking nut 34 locks the position of the support rod 33, it can support the pre-assembled component 300 and prevent the hydraulic lifting component 32 from retracting during the support process.

[0048] Specifically, after the support rod 33 is supported to the target position by the hydraulic lifting component 32, the locking nut 34 can rotate on the threaded portion 331, which can be understood as an external thread. By abutting the locking nut 34 against the base 10, the position of the support rod 33 can be fixed, and the support rod 33 can be mechanically locked. Since there are multiple locking nuts 34, they can be stacked. Any two adjacent locking nuts 34 abutting together can play an anti-loosening role, thereby further locking the position of the support rod 33. When the pre-assembled component 300 is in a horizontal state (see...), Figure 4 Adjust to a vertical position (see) Figure 6 When the pre-installed component 300 is in a position, it is not easy for the pre-installed component 300 to slip relative to each other, thus ensuring the positional accuracy of the pre-installed component 300.

[0049] In the above technical solution, the number of support rods 33 around the hydraulic lifting component 32 can be, but is not limited to, two, three, four, five, etc., and the number of locking nuts 34 can be, but is not limited to, two, three, four, five, etc.

[0050] In the above technical solutions, refer to Figure 4 The pre-assembled component 300 is fixed to the transport bracket 200 by fasteners 203. Two support devices 100 for the nuclear fusion device pre-assembled component are provided: one supports the lower window neck tube 301 of the pre-assembled component 300, and the other supports the high-field side 302 of the pre-assembled component 300. When the support device 100 of the nuclear fusion device pre-assembled component supports the lower window neck tube 301 and the high-field side 302 (the high-field side 302 can refer to the side with a higher magnetic field strength in the pre-assembled component 300), the hydraulic lifting component 32 is controlled to move closer to the pre-assembled component 300 in the second direction. The hydraulic lifting component 32 can provide a support preload in the second direction, and the support rod 33 moves along the second direction with the hydraulic lifting component 32, causing the support seat 31 to abut against the pre-assembled component 300. Then, the locking nut 34 is rotated, causing the locking nut 34 and the threaded portion 331 to engage so that the support rod 33 can be positioned relative to the base 10 in the second direction (in... Figure 4 The second direction of the state is left and right (locked). During the transportation of the pre-assembled component 300, the pre-assembled component 300 is always in a horizontal state.

[0051] When it is necessary to flip the pre-assembled component 300 from a horizontal to a vertical position (see...) Figure 6When the second direction is vertical, during the flipping process, the second support mechanism 30 provides vertical support for the pre-assembled component 300, providing rigid support for the pre-assembled component 300 to change from a horizontal to a vertical state. That is, the entire weight of the pre-assembled component 300 is applied to the support device 100 of the two nuclear fusion device pre-assembled components. Since the locking nut 34 and the threaded part 331 can mechanically lock the support rod 33 in the second direction (which is vertical), the second support mechanism 30 will not displace downwards when bearing the weight of the pre-assembled component 300. This prevents the pre-assembled component 300 from slipping relative to the pre-assembled component 300 during changes in attitude and center of gravity, ensuring the positional accuracy of the pre-assembled component 300.

[0052] Furthermore, the support of the hydraulic lifting component 32 relies entirely on the sealing of the hydraulic system. Insufficient oil volume, oil contamination (water, impurities), or excessively high / low oil viscosity (especially at extreme temperatures) can all affect performance and sealing, increasing the risk of pressure leakage. Without a separate, purely mechanical device to physically "lock" the piston rod or load platform to prevent accidental retraction, slow pressure release can lead to catastrophic consequences when people or equipment are working under the weight supported by the hydraulic lifting component 32. Additionally, once the component is lifted, the hydraulic lifting component 32 bears the weight, making precise fine-tuning (raising or lowering slightly) difficult in the supported state. Adjustments typically require slightly releasing pressure (risky) before pumping pressure again, which is inconvenient and potentially unsafe. Therefore, the hydraulic lifting component 32 of the second support mechanism 30 primarily provides preload, while the support function is mainly achieved by the support rod 33.

[0053] According to an embodiment of the present invention, the support device 100 for the pre-assembled component of the nuclear fusion device provides support for the pre-assembled component 300 in two directions via a first support mechanism 20 and a second support mechanism 30. The hydraulic lifting component 32 of the second support mechanism 30 can drive the support base 31 to abut against the pre-assembled component 300, providing a pre-tightening force in the second direction to the pre-assembled component 300. The support in the second direction can be mechanically locked by the cooperation of the support rod 33 and the locking nut 34. Thus, the second support mechanism 30 can provide rigid support for the pre-assembled component 300 to change from a horizontal state to a vertical state, which can prevent relative slippage of the pre-assembled component 300 during changes in attitude and center of gravity, improve the positional accuracy of the pre-assembled component 300, and facilitate the subsequent installation of the pre-assembled component 300.

[0054] In some embodiments of the present invention, reference is made to Figures 1 to 3The hydraulic lifting component 32 includes a main body 321 and a rod body 322. The main body 321 can drive the rod body 322 to move along a second direction. The second support mechanism 30 includes a support plate 35, which is vertically connected to the rod body 322. The support plate 35 has a through hole at the position corresponding to the support rod 33, and the support rod 33 passes through the through hole.

[0055] The main body 321 can refer to the main structure of the hydraulic lifting component 32, including the cylinder, hydraulic oil input or output, and other control valves. The rod body 322 can refer to the piston rod that outputs the lifting motion. Since the axial direction of the support rod 33 and the rod body 322 is consistent, both move in the second direction. The support plate 35 can move in the second direction with the rod body 322. The support plate 35 is a flat plate, and the through holes of the support plate 35 can guide the lifting of multiple support rods 33, so that the displacement of multiple support rods 33 in the second direction is consistent. This allows multiple support rods 33 to drive the support seat 31 to contact the pre-assembled component 300 simultaneously, thereby ensuring that the supporting force of multiple support rods 33 is consistent. This prevents the pre-assembled component 300 from tilting when it is adjusted from a horizontal state to a vertical state, and also prevents relative slippage of the pre-assembled component 300 during changes in posture and center of gravity, which helps to improve the positional accuracy of the pre-assembled component 300.

[0056] In some embodiments of the present invention, reference is made to Figure 2 and Figure 3 Multiple locking nuts 34 are located on the side of the support plate 35 near the base 10.

[0057] Multiple locking nuts 34 can move toward the side closer to the base 10 and abut against each other, thereby locking the support rod 33 by abutting against the base 10. Multiple locking nuts 34 can also move toward the side closer to the support plate 35 and abut against each other, i.e., locking the support rod 33 by abutting against the support plate 35.

[0058] The multiple locking nuts 34 can also be partially moved towards the side closer to the base 10 and partially moved towards the side closer to the support plate 35, thereby the locking nuts 34 mechanically lock the position of the support rod 33 by abutting against the base 10 and the support plate 35.

[0059] In the above technical solution, multiple locking nuts 34 are all located on the side of the support plate 35 near the base 10, which makes the arrangement of multiple locking nuts 34 on the support rod 33 more compact, reduces the number of locking nuts 34, reduces the volume of the support device 100 for the pre-assembled components of the nuclear fusion device, and also reduces the length of components such as the hydraulic lifting component 32 and the support rod 33 in the second direction, improves the structural strength of components such as the hydraulic lifting component 32 and the support rod 33, and improves the reliability of the support device 100 for the pre-assembled components of the nuclear fusion device.

[0060] In some embodiments of the present invention, reference is made to Figure 2 and Figure 3 The support rod 33 is provided with a limiting part 33a, and the second support mechanism 30 includes a limiting member 36. The limiting member 36 is adjustablely provided on the support plate 35 and can be adjusted to engage with the limiting part 33a when the support rod 33 is locked relative to the base 10 in the second direction.

[0061] The limiting part 33a can be, but is not limited to, a limiting groove, a limiting surface, etc. The limiting part 33a can be, but is not limited to, a limiting block, a limiting rod, etc. The limiting member 36 is adjustablely provided on the support plate 35. It can be understood that the limiting member 36 can be detachably provided on the support plate 35, or rotatably provided on the support plate 35, or horizontally movable provided on the support plate 35.

[0062] The support rod 33 and the support base 31 are not an integral structure; they are connected by, but not limited to, bolts, pins, or clips. Due to the significant weight of the pre-assembled component 300, relative rotation between the support rod 33 and the support base 31 can easily occur when adjusting from a horizontal to a vertical position, thus affecting the positional accuracy of the pre-assembled component 300. For example, ... Figure 1 As shown, the support rod 33 is connected to the flange seat 102 via a pin 101, and the flange seat 102 is connected to the support base 31 via bolts. In this structure, there is a small gap between the pin hole of the pin 101 and the pin hole of the flange seat 102, and there are also small gaps between the bolt and the bolt hole of the flange seat 102 and the bolt hole of the support base 31. Under the condition of high-precision positioning requirements for the pre-assembled assembly 300, during the process of adjusting the pre-assembled assembly 300 from a horizontal to a vertical state, these small gaps can easily cause the support rod 33 to rotate relative to the support base 31, thereby causing relative displacement of the pre-assembled assembly 300 and affecting the positional accuracy of the pre-assembled assembly 300.

[0063] In the above technical solution, the limiting part 33a and the limiting member 36 can restrict the rotation of the support rod 33 relative to the support plate 35, thus preventing the support rod 33 from rotating during the lifting and lowering process of the hydraulic lifting member 32, thereby ensuring that the pre-assembled component 300 will not rotate. On the other hand, it can also prevent the pre-assembled component 300 from slipping relative to the changes in posture and center of gravity, thus meeting the high-precision position requirements of the pre-assembled component 300.

[0064] In some embodiments of the present invention, reference is made to Figure 1 and Figure 2The base 10 includes a base body 11 and a transition frame 12. The transition frame 12 includes a first plate 121, a second plate 122 and a connecting component 123. The first plate 121 and the second plate 122 are parallel to each other and connected by the connecting component 123. The first plate 121 is connected to the base body 11. The support rod 33 passes through the second plate 122 along the second direction and is guided and engaged with the second plate 122 and the first plate 121. The first support mechanism 20 is provided on the connecting component 123.

[0065] In the above technical solution, the second plate 122 and the first plate 121 are spaced apart in a second direction. The support rod 33 passes through the second plate 122 along the second direction and is guided and engaged with the second plate 122 and the first plate 121. Thus, the second plate 122 and the first plate 121 can provide support and guidance for two positions of the support rod 33. For example, referring to... Figure 1 The second plate 122 and the first plate 121 provide support and guidance on the upper and lower sides of the support rod 33, thereby preventing the support rod 33 from deviating relative to the second direction during movement and improving the reliability of the support rod 33's movement in the second direction. The second plate 122 and the first plate 121 also restrain and limit the support rod 33 in the first direction, improving the support reliability of the support rod 33 in the second direction. This allows for better support of the pre-assembled component 300 when it is in a vertical state, thus preventing relative slippage of the pre-assembled component 300 during changes in attitude and center of gravity, and improving the positional accuracy of the pre-assembled component 300 during the adjustment from a horizontal to a vertical state.

[0066] In some embodiments of the present invention, reference is made to Figures 1 to 3 The first plate 121 is provided with a first guide sleeve 1211 at the position corresponding to the support rod 33, and the second plate 122 is provided with a second guide sleeve 1221 at the position corresponding to the support rod 33. The support rod 33 is slidably fitted on the first guide sleeve 1211 and the second guide sleeve 1221, and the part of the support rod 33 that fits with the second guide sleeve 1221 is a smooth rod.

[0067] The first guide sleeve 1211 and the second guide sleeve 1221 also provide guidance for the support rod 33, further improving the reliability of the support rod 33's movement in the second direction and also enhancing the support reliability of the support rod 33 in the second direction. When the pre-assembled assembly 300 is adjusted from a horizontal to a vertical state, the second direction can refer to the vertical direction. Since the second guide sleeve 1221 is closer to the support base 31, the part where the support rod 33 and the second guide sleeve 1221 meet is a smooth rod. Therefore, the contact position between the support rod 33 and the second guide sleeve 1221 is a surface contact, resulting in higher contact strength. This prevents deformation at the contact point between the support rod 33 and the inner wall of the second guide sleeve 1221, thus avoiding the risk of gaps between the support rod 33 and the second guide sleeve 1221. This prevents displacement of the pre-assembled assembly 300 when it is adjusted from a horizontal to a vertical state, improving the support reliability of the second support mechanism 30 for the pre-assembled assembly 300 and consequently improving the positional accuracy of the pre-assembled assembly 300.

[0068] In some embodiments of the present invention, reference is made to Figures 1 to 3 The connecting component 123 includes a connecting rod 1231 and a third plate 1232. Multiple connecting rods 1231 are arranged around the first plate 121. The hydraulic lifting component 32 and multiple support rods 33 are located in the area enclosed by the multiple connecting rods 1231. The third plate 1232 is vertically connected to the first plate 121 and the second plate 122, and is connected to the first support mechanism 20.

[0069] The number of connecting rods 1231 can be, but is not limited to, two, three, four, five, etc.

[0070] It is understandable that the hydraulic lifting component 32 is centrally arranged on the first plate 121, and multiple support rods 33 and multiple connecting rods 1231 are arranged in a ring around the hydraulic lifting component 32. The multiple connecting rods 1231 are far away from the hydraulic lifting component 32 relative to the multiple support rods 33. That is, the multiple support rods 33 form an inner ring structure, and the multiple connecting rods 1231 form an outer ring structure.

[0071] Based on the preceding analysis, the transition frame 12 provides guidance and rigid support for multiple support rods 33. In the above technical solution, by configuring the connecting component 123 to include a connecting rod 1231 and a third plate 1232, the connecting rod 1231 and the third plate 1232 can provide stronger support strength between the first plate 121 and the second plate 122. This can improve the overall structural strength and rigidity of the transition frame 12, which helps to further improve the guiding reliability of the multiple support rods 33 and the support strength of the multiple support rods 33 for the pre-installed component 300, thereby further improving the reliability of the support device 100 for the pre-installed component of the nuclear fusion device.

[0072] In some embodiments of the present invention, reference is made to Figure 1 and Figure 2 The support base 31 includes a support body 311, a bottom support plate 312, and a connecting plate 313. The end of the support body 311 away from the bottom support plate 312 is constructed with a contoured support surface 31a. The bottom support plate 312 is connected to the hydraulic lifting component 32 and the support rod 33, and is connected to the support body 311 through the connecting plate 313. There are multiple connecting plates 313, which are arranged around the circumference of the bottom support plate 312.

[0073] The number of connecting plates 313 can be, but is not limited to, two, three, four, five, etc.

[0074] The shape of the contoured support surface 31a matches the shape of the position on the pre-assembled component 300 that needs to be supported. For example, the support device 100 of the pre-assembled component of the nuclear fusion device can be used to support the lower window neck tube 301 and the high field side 302 of the pre-assembled component 300. The contoured support surface 31a can be pre-processed to a corresponding shape according to the surface shape of the lower window neck tube 301 and the high field side 302, so that the support body 311 can fit with the surface of the lower window neck tube 301 and the high field side 302.

[0075] Understandably, the contoured support surface 31a allows the support body 311 and the pre-installed component 300 to fit together, increasing the contact area between the support device 100 and the pre-installed component 300, thus improving the stability of the support device 100 and preventing relative slippage of the pre-installed component 300 during changes in attitude and center of gravity. This also improves the positional accuracy of the pre-installed component 300 and facilitates subsequent installation. The circumferential arrangement of multiple connecting plates 313 around the bottom support plate 312 enhances the structural strength of the support base 31, ensuring that the support device 100 provides rigid support for the pre-installed component 300 from a horizontal to a vertical position, thereby improving the reliability of the support device 100.

[0076] Secondly, the support base 31 adopts a structure including a support body 311, a bottom support plate 312 and a connecting plate 313. While ensuring that the support base 31 has high structural strength, it can also reduce weight, which is beneficial for the pre-installed component 300 to be adjusted from a horizontal state to a vertical state.

[0077] In some embodiments of the present invention, reference is made to Figure 1 and Figure 2 The support body 311 includes a support base plate 3111 and an insulating pad 3112. The support base plate 3111 is connected to a connecting plate 313. The insulating pad 3112 is detachably mounted on the support base plate 3111 and has a contoured support surface 31a.

[0078] The insulating gasket 3112 can be made of, but is not limited to, rubber, plastic polymers, fiber reinforcement and other special materials.

[0079] In the above technical solution, the design of the insulating gasket 3112 can, on the one hand, avoid rigid contact between the support body 311 and the pre-assembled component 300, prevent damage to the pre-assembled component 300 when the support body 311 supports the pre-assembled component 300 in the vertical direction, and ensure the safety of the pre-assembled component 300. On the other hand, since the nuclear fusion device should avoid contamination by foreign materials as much as possible during the assembly process, the use of the insulating gasket 3112 can also avoid material contamination caused by direct contact between the support base plate 3111 and the pre-assembled component 300, and ensure the reliability of the pre-assembled component 300.

[0080] like Figure 4 As for Figure 6 As shown in the embodiment of the present invention, a feeding device 1000 for a pre-assembled component of a nuclear fusion device is also provided, including a transport bracket 200, a pre-assembled component 300, and a support device 100 for the pre-assembled component of the nuclear fusion device.

[0081] The transport support 200 includes a first part 201 and a second part 202 that are perpendicular to each other; the pre-assembly assembly 300 is mounted on the first part 201 by fasteners 203, and the pre-assembly assembly 300 has a lower window neck tube 301 and a high field side 302, which are close to the second part 202; the support device 100 for the nuclear fusion device pre-assembly assembly can refer to the support device 100 for the nuclear fusion device pre-assembly assembly of any of the embodiments described above. There are two support devices 100 for the nuclear fusion device pre-assembly assembly, one of which is supported on the lower window neck tube 301 and the other is supported on the high field side 302. The base 10 is connected to the second part 202, and the first support mechanism 20 is supported on the first part 201.

[0082] There can be multiple fasteners 203, which are arranged around the pre-assembled component 300 to ensure the connection strength between the pre-assembled component 300 and the first part 201. The fasteners 203 can be, but are not limited to, cable ties, bolts, clips, etc.

[0083] According to an embodiment of the present invention, the delivery device 1000 for the pre-assembly component of the nuclear fusion device, the transport bracket 200 and the pre-assembly component 300 are connected to the support device 100 for the pre-assembly component of the nuclear fusion device via fasteners 203. The support device 100 for the pre-assembly component of the nuclear fusion device can provide better rigid support for the pre-assembly component 300 from a horizontal state to a vertical state, avoid relative slippage of the pre-assembly component 300 during changes in attitude and center of gravity, and improve the positional accuracy of the pre-assembly component 300.
