Description

[0002] A tokamak is a device for controlled nuclear fusion, which mainly controls high-temperature plasma by magnetic confinement, so that the plasma in the vacuum chamber occurs fusion reaction to release huge energy, which is finally converted for human use. In the middle of the tokamak, there is a large annular pressure vessel, which needs to be evenly divided along the ring direction to ensure that each sector is relatively independent. In the overall assembly process, each tokamak sector includes a vacuum chamber, a vacuum chamber cold shield and a TF magnet (superconducting magnet). For convenience of description, the assembly of the vacuum chamber, the vacuum chamber cold shield and the TF magnet in each sector can be referred to as a pre-assembled component. Since the vacuum chamber and the TF magnet in each pre-assembled component are heavy (> 50t) by themselves, the center of gravity needs to be lowered during transportation, and the components need to be adjusted to a vertical state during overall assembly. Therefore, the attitude needs to be adjusted from horizontal to vertical during on-site installation. During the overall attitude adjustment process, the height of the center of gravity of the pre-assembled component will change greatly, and the direction of the supporting force will also change. Therefore, how to meet the position accuracy of the large-weight and large-volume pre-assembled component during the attitude adjustment process has become one of the problems to be solved. SUMMARY

[0023] In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified. In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] The support device 100 of the pre-assembled component of the nuclear fusion device can be used for the pre-assembled component 300, the nuclear fusion device can include a plurality of pre-assembled components 300, and the plurality of pre-assembled components 300 are sequentially spliced into a ring along a circumferential direction. The pre-assembled component 300 is in a whole fan shape, and can include a vacuum chamber, a vacuum chamber cold shield, and a TF magnet. Wherein, the composition and operation of the nuclear fusion device are known to those skilled in the art, and will not be repeated here. In addition, the support device 100 of the pre-assembled component of the nuclear fusion device can also be applied to other heavy load components and similar scenarios.

[0025] The support device 100 of the pre-assembled component of the nuclear fusion device according to the embodiments of the present application will be described below with reference to Figures 1-6 .

[0026] As shown in Figures 1 to 3 , the support device 100 of the pre-assembled component of the nuclear fusion device according to the embodiments of the present application comprises 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, and the second direction is perpendicular to the first direction. The second support mechanism 30 comprises a support seat 31, a hydraulic lifting piece 32, a support rod 33 and a locking nut 34. The support seat 31 is connected to the base 10 through the hydraulic lifting piece 32 and the support rod 33. The support rod 33 is provided in a plurality of circumferential directions around the hydraulic lifting piece 32. Each support rod 33 is guided in the second direction with the base 10 and is provided with a threaded portion 331. The locking nut 34 is provided in a plurality of threaded portions 331 and is installed on the threaded portion 331. The locking nut 34 and the threaded portion 331 cooperate to lock the support rod 33 relative to the base 10 in the second direction.

[0027] The base 10 can refer to a component for providing a mounting basis for the first support mechanism 20 and the second support mechanism 30, which can be but is not limited to high-strength materials such as alloy steel, stainless steel, composite materials, etc. The base 10 can be but is not limited to a frame structure, a column structure, and a composite structure composed of a frame structure and a column structure, etc.

[0028] The first support mechanism 20 can refer to a mechanism for supporting the pre-assembled component 300 along the first direction and connecting 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. As an example, referring to Figure 1 , the first support mechanism 20 can be a support beam. Wherein, the first direction can refer to the left-right direction of Figure 1 , and in combination with Figure 4 , the first direction is the up-down direction of Figure 4 , that is, when the pre-assembled component 300 is in a horizontal state, the first support mechanism 20 can support the whole nuclear fusion device pre-assembled component support device 100 in the vertical direction.

[0029] The second support mechanism 30 can refer to a mechanism for supporting the pre-assembly component 300 in a second direction. Referring to Figure 1 , the second direction can be the up-down direction of Figure 1 , in combination with Figure 4 , the second direction can be the left-right direction of Figure 4 .

[0030] In the above technical solution, the second support mechanism 30 includes a support seat 31, a hydraulic lifting piece 32, a support rod 33, and a locking nut 34. The support seat 31 can refer to a component in the second support mechanism 30 that contacts the pre-assembly component 300, which can be but is not limited to a frame structure, a plate structure, or a beam structure, etc. The hydraulic lifting piece 32 can refer to a component that controls the lifting of the support seat 31, which can be but is not limited to a hydraulic cylinder and a hydraulic rod, etc. The support rod 33 can refer to a component that supports the support seat 31, which is provided in multiple around the circumference of the hydraulic lifting piece 32, each support rod 33 is guided in the second direction with the base 10, can follow the lifting of the hydraulic lifting piece 32, and supports the support seat 31. The support rod 33 is provided with a threaded portion 331, and the locking nut 34 is provided in multiple and installed on the threaded portion 331. The locking nut 34 and the threaded portion 331 cooperate to lock the support rod 33 in the second direction relative to the base 10, which can limit the displacement of the base 10 in the second direction. For example, when the pre-assembly component 300 is adjusted from a horizontal state (see Figure 4 ) to a vertical state (see Figure 6 ), the locking nut 34 can lock the position of the support rod 33, which can support the pre-assembly component 300 and prevent the hydraulic lifting piece 32 from retracting during the support process.

[0031] Specifically, when the support rod 33 is supported to the target position with the hydraulic lifting piece 32, the locking nut 34 can be rotated 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 the locking nut 34 is provided in multiple, the multiple locking nuts 34 can be stacked and arranged, and any two adjacent locking nuts 34 abutting together can play a role in preventing loosening, thereby further locking the position of the support rod 33. When the pre-assembly component 300 is adjusted from a horizontal state (see Figure 4 ) to a vertical state (see Figure 6 ), the pre-assembly component 300 is not easy to slip relative to the base 10, thereby ensuring the position accuracy of the pre-assembly component 300.

[0032] In the above technical solution, the number of support rods 33 around the hydraulic lifting piece 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.

[0033] In the above technical solution, the reference Figure 4 , the pre-assembly 300 is fixed on the transport support 200 by the fastener 203, and the two nuclear fusion device pre-assembly support devices 100 are arranged on the lower window neck pipe 301 and the high-field side 302 of the pre-assembly 300. When the nuclear fusion device pre-assembly support devices 100 support the lower window neck pipe 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-assembly 300), the hydraulic lifting member 32 is controlled to move close to the pre-assembly 300 in the second direction, the hydraulic lifting member 32 can provide a support pre-tightening force in the second direction, and the support rod 33 moves along the hydraulic lifting member 32 in the second direction, so that the support base 31 abuts against the pre-assembly 300, and then the locking nut 34 is rotated to cooperate with the threaded portion 331 to lock the support rod 33 relative to the base 10 in the second direction (the second direction is the left-right direction in the state shown in Figure 4 ). During the transportation of the pre-assembly 300, the pre-assembly 300 is always in a horizontal state.

[0034] When it is necessary to flip the pre-assembly 300 from the horizontal state to the vertical state (see Figure 6 , at this time the second direction is the vertical direction), during the flipping process, the second support mechanism 30 bears the support of the pre-assembly 300 in the vertical direction, and provides rigid support for the pre-assembly 300 when it is converted from the horizontal state to the vertical state, that is, the gravity of the pre-assembly 300 is entirely borne by the two nuclear fusion device pre-assembly support devices 100. Since the cooperation of the locking nut 34 and the threaded portion 331 can mechanically lock the support rod 33 in the second direction (at this time the second direction is the vertical direction), the second support mechanism 30 will not be displaced downward when bearing the gravity of the pre-assembly 300, thereby preventing the pre-assembly 300 from slipping relative to the position during the change of the attitude and the center of gravity, and ensuring the position accuracy of the pre-assembly 300.

[0035] In addition, the support of the hydraulic lifting device 32 entirely depends on the sealing of the hydraulic system. At the same time, insufficient oil, oil pollution (water, impurities) or oil viscosity that is too high / low (especially at extreme temperatures) can affect performance and sealing, increasing the risk of pressure relief. If it does not have an independent, purely mechanical device to physically "catch" the piston rod or the load platform, preventing it from accidentally retracting. Slow pressure relief can lead to catastrophic consequences when a person or equipment is working under the weight supported by the hydraulic lifting device 32. In addition, once the components are lifted, the hydraulic lifting device 32 bears the weight and usually cannot easily make precise fine adjustments (raise or lower a little bit) in the supporting state. Adjustment usually requires first slightly releasing the pressure (with risk), then pumping, which is inconvenient and potentially unsafe. Therefore, the hydraulic lifting device 32 of the second support mechanism 30 mainly undertakes the role of providing pre-tightening force, and the support role is mainly implemented by the support rod 33.

[0036] The support device 100 of the nuclear fusion device pre-assembly according to the embodiments of the present application, the first support mechanism 20 and the second support mechanism 30 can provide two-directional support for the pre-assembly 300, and the hydraulic lifting device 32 of the second support mechanism 30 can drive the support seat 31 to abut against the pre-assembly 300, and provide pre-tightening force in the second direction for the pre-assembly 300, and the support in the second direction can be mechanically locked by cooperation of the support rod 33 and the locking nut 34, so that the second support mechanism 30 can provide rigid support for the pre-assembly 300 when the pre-assembly 300 is converted from a horizontal state to a vertical state, can avoid relative slipping of the pre-assembly 300 in the process of changing attitude and gravity center, improve the position accuracy of the pre-assembly 300, and facilitate subsequent installation of the pre-assembly 300.

[0037] In some embodiments of the present application, with reference to Figures 1 to 3 The hydraulic lifting device 32 includes a main body part 321 and a rod body part 322, and the main body part 321 can drive the rod body part 322 to move in the second direction; the second support mechanism 30 includes a support plate 35, the support plate 35 is connected to the rod body part 322 vertically, the support plate 35 is provided with a through hole corresponding to the position of the support rod 33, and the support rod 33 is arranged in the through hole.

[0038] The main body part 321 can refer to the main body structure of the hydraulic lifting device 32, which includes a cylinder, hydraulic oil input or output, and other control valves. The rod body part 322 can refer to the piston rod that outputs the lifting motion. Since the axial directions of the support rods 33 and the rod body part 322 are consistent, both move in the second direction, the support plate 35 can move in the second direction along with the rod body part 322. The support plate 35 is a flat plate, and the multiple support rods 33 can be guided in lifting through the through holes of the support plate 35, so that the displacements of the multiple support rods 33 in the second direction are consistent, and the multiple support rods 33 can drive the support seat 31 to simultaneously contact the pre-assembly component 300, thereby ensuring that the support forces of the multiple support rods 33 remain consistent, avoiding tilting of the pre-assembly component 300 when adjusting from a horizontal state to a vertical state, and thereby avoiding relative slipping of the pre-assembly component 300 during changes in posture and center of gravity, which is conducive to improving the position accuracy of the pre-assembly component 300.

[0039] In some embodiments of the present application, with reference to Figure 2 and Figure 3 The multiple locking nuts 34 are arranged on one side of the support plate 35 close to the base 10.

[0040] The multiple locking nuts 34 can move towards the side close to the base 10 and abut each other, and the locking nuts 34 lock the support rods 33 by abutting the base 10. The multiple locking nuts 34 can also move towards the side close to the support plate 35 and abut each other, that is, the locking nuts 34 lock the support rods 33 by abutting the support plate 35.

[0041] The multiple locking nuts 34 can also move towards the side close to the base 10 on one part and move towards the side close to the support plate 35 on the other part, so that the locking nuts 34 abut the base 10 and the support plate 35 to jointly mechanically lock the positions of the support rods 33.

[0042] In the above technical solution, the multiple locking nuts 34 are arranged on one side of the support plate 35 close to the base 10, which can make the arrangement of the multiple locking nuts 34 on the support rods 33 more compact, reduce the number of locking nuts 34, reduce the volume of the support device 100 of the pre-assembly component of the nuclear fusion device, and also can reduce the lengths of the hydraulic lifting device 32, the support rods 33 and other components in the second direction, improve the structural strength of the hydraulic lifting device 32, the support rods 33 and other components, and improve the reliability of the support device 100 of the pre-assembly component of the nuclear fusion device.

[0043] In some embodiments of the present application, with reference to Figure 2 and Figure 3 The support rods 33 are provided with limiting parts 33a, and the second support mechanism 30 includes a limiting part 36 adjustably arranged on the support plate 35 and adjustably combined with the limiting parts 33a when the support rods 33 are locked in the second direction relative to the base 10.

[0044] 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 piece 36 is adjustably arranged on the support plate 35, which can be understood as that the limiting piece 36 can be detachably arranged on the support plate 35, or rotatably arranged on the support plate 35, or horizontally movably arranged on the support plate 35.

[0045] The support rod 33 and the support base 31 are non-integral structures, and are connected through, but not limited to, bolts, pins or buckles. Since the weight of the pre-assembly 300 is large, when the pre-assembly 300 is adjusted from a horizontal state to a vertical state, the relative rotation of the support rod 33 and the support base 31 is easily caused, which further affects the position accuracy of the pre-assembly 300. For example, as shown in FIG. 1, the support rod 33 is connected to the flange seat 102 through the pin shaft 101, and the flange seat 102 is connected to the support base 31 through bolts. In this structure, there is a small gap between the pin shaft 101 and the pin hole of the flange seat 102, and there is also a small gap between the bolts and the bolt holes of the flange seat 102 and the support base 31. In the case of high-precision position requirement of the pre-assembly 300, during the process of adjusting the pre-assembly 300 from the horizontal state to the vertical state, these small gaps easily cause the relative rotation of the support rod 33 and the support base 31, which further causes the relative displacement of the pre-assembly 300, and thus affects the position accuracy of the pre-assembly 300. Figure 1 In the above technical solution, the cooperation of the limiting part 33a and the limiting piece 36 can limit the relative rotation of the support rod 33 and the support plate 35, which can avoid the rotation of the support rod 33 during the lifting process of the hydraulic lifting piece 32, and further ensure that the pre-assembly 300 will not rotate, so as to avoid the relative sliding of the pre-assembly 300 during the change of the posture and the center of gravity, and meet the high-precision position requirement of the pre-assembly 300.

[0046] In some embodiments of the present application, referring to FIGS. 1 and 2, the base 10 includes a base body 11 and an adapter frame 12, the adapter frame 12 includes a first plate body 121, a second plate body 122 and a connecting component 123, the first plate body 121 and the second plate body 122 are parallel to each other and connected through the connecting component 123, the first plate body 121 is connected to the base body 11, the support rod 33 is arranged in the second plate body 122 along the second direction and guided and matched with the first plate body 121, and the first support mechanism 20 is arranged on the connecting component 123.

[0047] Figure 1 Figure 2

[0048] ​​​In the technical solution, the second plate body 122 and the first plate body 121 are spaced apart in the second direction, the support rod 33 is arranged through the second plate body 122 in the second direction, and the support rod 33 is guided and matched with the second plate body 122 and the first plate body 121. Therefore, the second plate body 122 and the first plate body 121 can provide support and guidance for two positions of the support rod 33, for example, referring to Figure 1 , the second plate body 122 and the first plate body 121 can provide support and guidance on both upper and lower sides of the support rod 33. Therefore, the support rod 33 can be prevented from being deflected relative to the second direction during movement, and the reliability of the support rod 33 in the second direction is improved. The second plate body 122 and the first plate body 121 can also play a role in restraining and limiting the support rod 33 in the first direction, thereby improving the support reliability of the support rod 33 in the second direction, better supporting the pre-assembly component 300 when the pre-assembly component 300 is in a vertical state, and further preventing the pre-assembly component 300 from slipping relative to the second direction during changes in posture and gravity center. This is conducive to improving the position accuracy of the pre-assembly component 300 during adjustment from a horizontal state to a vertical state.

[0049] In some embodiments of the present application, referring to Figures 1 to 3 , the first plate body 121 is provided with a first guide sleeve 1211 corresponding to the position of the support rod 33, and the second plate body 122 is provided with a second guide sleeve 1221 corresponding to the position of the support rod 33.
