Description

Technical Field

[0001] The invention relates to the technical field of nuclear fusion devices, and in particular to an assembling method of an adjusting device and an annular limiter. Background Art

[0002] The Dewar base is a key component in the installation of a nuclear fusion device. It serves as the support and installation foundation for all important equipment in the main system of the nuclear fusion device. Deformation during transportation has a significant impact on the main structure and the installation of important components. During the installation of the Dewar base, an annular limiter is required. The annular limiter can adjust the position of the Dewar base and also has the function of limiting the position of the Dewar base.

[0003] Due to the large size of the circumferential limiter (1.3m×0.4m×0.4m), the weight of 600kg, the high installation precision in multiple directions (adjustment precision of 0.5mm), and the narrow installation space (bottom adjustment space of 50mm), higher requirements are placed on the adjustment tooling and methods to ensure that the position of the circumferential limiter is adjusted according to the on-site measurement data during installation, and to ensure that the circumferential limiter meets the position requirements after installation. Conventional adjustment methods basically do not require fixation of the adjustment tooling, have a large adjustment space, have low precision requirements in a single direction and installation precision, and do not require a guide. When there are requirements to adjust components that are large in size, heavy in weight, have high precision requirements in multiple directions and installation precision, have a narrow adjustment space, and are difficult to clamp, conventional adjustment tools and methods cannot meet the precision requirements of the components when adjusting them.

[0045] like Figure 1 and Figure 2 As shown, the adjustment device 100 of the embodiment of the present invention is used to adjust the annular stopper 200, which is a component used to fix the dewar base of a nuclear fusion device. The annular stopper 200 is provided on a wall 300, wherein the wall 300 can be referred to as a biological shielding wall in the field of nuclear fusion devices. The annular stopper 200 can be arranged in a plurality of circumferential directions within the wall 300. The dewar base can be arranged in a PIT foundation pit 310 of the wall 300 and cooperate with the plurality of annular stoppers 200 for positional limitation.

[0046] Reference below Figure 3-Figure 8 , describing the adjustment device 100 according to an embodiment of the present invention.

[0047] like Figure 3 and Figure 4 As shown, the adjusting device 100 of the embodiment of the present invention includes: a base 10, a moving member 20, a limiting member 30, a second adjusting member 40 and a third adjusting member 50. The moving member 20 is movably arranged on the base 10 along the first direction; a plurality of limiting members 30 are arranged on the moving member 20 and are spaced apart along the first direction, and are used to limit the annular limiter 200. The limiting member 30 includes a support 31 and a first adjusting member 32. The first adjusting member 32 is arranged on the support 31 and is movable in the first direction; the second adjusting member 40 is arranged on the moving member 20 and is height-adjustable in the vertical direction. The vertical direction is perpendicular to the first direction. The second adjusting member 40 is used to support the annular limiter 200; the third adjusting member 50 is arranged on the base 10 and can drive the moving member 20 to move along the first direction.

[0048] The base 10 may refer to a basic supporting structure for the adjustment device 100 and may be made of, but not limited to, alloy steel, stainless steel, aluminum alloy, composite material, etc. The base 10 may be made of, but not limited to, a plate, a block, etc.

[0049] The moving member 20 may refer to a component provided on the base 10 and movable along the first direction, and may be, but not limited to, a plate, a block, etc. Figure 3 , the “first direction” may refer to the left-right direction.

[0050] The limiting component 30 may refer to a component for limiting the annular limiter 200. The connection between the limiting component 30 and the moving member 20 may be, but is not limited to, welding, bolt connection, riveting, etc. The limiting components 30 are arranged on the moving member 20 and spaced apart along the first direction. The number of the limiting components 30 may be, but is not limited to, two, three, four, etc. For example, referring to Figure 3 , there can be two limiting components 30.

[0051] In the above embodiment, the limiting component 30 may include a support 31 and a first adjusting member 32. The support 31 may be a component for supporting the first adjusting member 32. The first adjusting member 32 may be a component disposed on the support 31 and capable of an adjustment stroke along a first direction, and may be, but is not limited to, a screw, a jackscrew, a bolt, a hydraulic cylinder, a pneumatic cylinder, an electric push rod, a wedge block adjustment mechanism, and the like.

[0052] Optionally, refer to Figure 4 The annular limiter 200 may be provided with two limit slots 220 disposed face to face, and the limit member 30 may be used to cooperate with the limit slots 220 to limit the annular limiter 200. For example, the first adjustment member 32 may abut against the wall of the limit slot 220 in the first direction to play a limiting role.

[0053] The second adjusting member 40 may be a member provided on the moving member 20 and capable of being adjusted in the vertical direction. The second adjusting member 40 may be, but is not limited to, a screw, a jackscrew, a bolt, a hydraulic cylinder, an air cylinder, an electric push rod, a wedge block adjustment mechanism, and the like. Figure 3 The “vertical direction” may refer to the up and down direction, and the adjustment range of the second adjusting member 40 in the vertical direction may be 0 mm to 11 mm.

[0054] The third adjusting member 50 may be a component provided on the base 10 and capable of driving the moving member 20 to move along the first direction, and may adjust the position of the annular stopper 200 in the first direction. The adjustment range of the third adjusting member 50 in the first direction may be 0 mm to 79 mm.

[0055] In the above technical solution, since the limiting component 30 includes a support 31 and a first adjusting component 32, the first adjusting component 32 can be adjusted on the support 31, which makes it easy to match the annular limiter 200 with the limiting component 30, and then the annular limiter 200 is limited in the horizontal direction by adjusting the first adjusting component 32. The annular limiter 200 can be supported in the vertical direction by the second adjusting component 40. At the same time, since the second adjusting component 40 can be height-adjustable in the vertical direction, the precise position of the annular limiter 200 in the vertical direction can be adjusted. Then, by driving the movable member 20 to move in the first direction through the third adjusting component 50, the horizontal position of the annular limiter 200 relative to the wall 300 can be adjusted, thereby achieving precise installation of the annular limiter 200 on the wall 300.

[0056] According to the adjusting device 100 of the embodiment of the present invention, the circumferential limiter 200 can be fixed on the movable part 20 through the limiting component 30 and the second adjusting component 40, and the circumferential limiter 200 can be adjusted horizontally and vertically, and the movable part 20 can be driven to move along the first direction through the third adjusting component 50. It can be suitable for position adjustment of the circumferential limiter 200 that is large in size, heavy in weight, has precision requirements in multiple directions, has high installation precision, has a narrow adjustment space, and is difficult to clamp. It can also adjust the horizontal position of the circumferential limiter 200, improve the installation precision of the circumferential limiter 200, and thus improve the installation reliability of the Dewar base.

[0057] In some embodiments of the present invention, reference Figure 3 and Figure 4 The first adjusting member 32 and the second adjusting member 40 are provided with an insulating member 70. The insulating member 70 can be, but is not limited to, a glass fiber resin material, a ceramic insulating sheet, a polytetrafluoroethylene material, and the like.

[0058] Since the nuclear fusion device has high requirements for the internal environment during the installation process, in the above technical solution, an insulating member 70 is provided on the first adjusting member 32 and the second adjusting member 40. The insulating member 70 can not only play an insulating role to avoid the generation of secondary electric fields, but also prevent the first adjusting member 32 and the second adjusting member 40 from directly contacting the annular limiter 200, thereby reducing the risk of the annular limiter 200 being scratched and the risk of generating debris, thereby reducing material contamination.

[0059] In some embodiments of the present invention, reference Figures 3 to 5 The support 31 includes a first part 311 and a second part 312. The first part 311 is arranged on the movable part 20. The second part 312 is detachably arranged on the first part 311 and is provided with a first adjusting part 32. The height of the first part 311 is less than the minimum height of the second adjusting part 40.

[0060] The connection between the first part 311 and the second part 312 can be, but is not limited to, a snap connection, a bolt connection, etc. Figure 4 The connection between the first part 311 and the second part 312 can be a bolt connection.

[0061] In the above technical solution, the second portion 312 is detachably mounted on the first portion 311. This allows for the removal and replacement of the second portion 312 or the first adjusting member 32 when they become worn or damaged, thus preventing the entire adjusting device 100 from being scrapped due to a single component failure. Furthermore, the second portion 312 is detachably mounted on the first portion 311, and the height of the first portion 311 is less than the minimum height of the second adjusting member 40. This allows the first portion 311 to be removed after the adjusting device 100 has completed its operation, allowing the adjusting device 100 to be removed from below the annular stopper 200, thereby facilitating the use of the entire device.

[0062] In some embodiments of the present invention, reference Figure 6 The first part 311 includes a first plate 3111, a second plate 3112 and a third plate 3113. The second plate 3112 and the third plate 3113 are arranged on the same side of the first plate 3111 and are spaced apart along the second direction. The second direction is perpendicular to the first direction and the vertical direction. The first plate 3111, the second plate 3112 and the third plate 3113 are all connected to the moving part 20, wherein the first plate 3111 and the second part 312 are detachably connected.

[0063] It is understood that the “second direction” can refer to Figure 4 The front and back direction.

[0064] The first plate 3111, the second plate 3112 and the third plate 3113 may be plate-shaped structures, and the connection method of the first plate 3111, the second plate 3112 and the third plate 3113 may be, but is not limited to, welding, integral molding, riveting, etc. The angle between the first plate 3111 and the third plate 3113 and the second plate 3112 may be 90 degrees, or may be greater than or less than 90 degrees. For example, referring to Figure 6 The first plate 3111 and the third plate 3113 are at an angle of 90° to the second plate 3112, and the first plate 3111, the second plate 3112 and the third plate 3113 form a U-shaped rigid frame (see Figure 3 and Figure 4 ), which can effectively resist forces and torques from different directions, prevent the first part 311 from being deformed due to uneven force, and improve the reliability of the first part 311.

[0065] In the above technical solution, the first plate 3111 serves as a core bearing plate, is directly fixedly connected to the movable member 20, and is detachably connected to the second portion 312. The frame structure formed by the first plate 3111, the second plate 3112, and the third plate 3113 can improve the structural strength of the second portion 312 and prevent the second portion 312 from being deformed by force. The second plate 3112 and the third plate 3113 are located on the same side of the first plate 3111, are spaced apart along the second direction, and are both fixedly connected to the movable member 20 to form a support frame. This can improve the structural strength of the first plate 3111, further improve the structural strength of the second portion 312, and thereby improve the overall structural strength of the support 31. It can also improve the reliability of the limiting component 30 on the annular limiter 200, thereby ensuring the reliability of the adjusting device 100. At the same time, the first plate 3111 , the second plate 3112 and the third plate 3113 have simple structures, which can save materials of the adjusting device 100 , reduce the weight of the adjusting device 100 , and facilitate the adjustment of the annular limiter 200 .

[0066] In some embodiments of the present invention, reference Figures 4 to 7 The second part 312 is flat and is arranged on the other side of the first plate 3111 away from the second plate 3112 and the third plate 3113. The bottom of the second part 312 is attached to the upper surface of the movable part 20; wherein the first adjusting part 32 is a threaded adjusting part and is screwed to the second part 312.

[0067] It can be understood that the first adjusting member 32 can be but not limited to a screw, a bolt, a top screw, etc., and the second part 312 is provided with a threaded hole that cooperates with the first adjusting member 32. Rotating the first adjusting member 32 can move along the first direction on the second part 312, thereby making one end of the first adjusting member 32 tighten the annular limiter 200, thereby limiting the annular limiter 200 in the first direction.

[0068] In the above technical solution, the second portion 312 is flat, has a simple structure, is easy to process and assemble, and can reduce manufacturing costs. The bottom of the second portion 312 is in contact with the upper surface of the movable member 20, and is arranged on both sides of the first plate 3111 together with the second plate 3112 and the third plate 3113. This can further improve the structural strength of the support 31 and thereby enhance the reliability of the positioning of the annular limiter 200. The first adjustment member 32 is a threaded adjustment member with a simple structure and a small footprint, which can improve space utilization and facilitate positioning operations in narrow spaces.

[0069] In some embodiments of the present invention, reference Figures 4 to 7 There are at least two second adjusting members 40, and the second adjusting members 40 are lifting members that can be raised and lowered in the vertical direction.

[0070] The second adjusting member 40 may be, but is not limited to, a jack, an electric push rod, a cylinder, a hydraulic cylinder, a pneumatic adjusting column, etc. The number of the second adjusting member 40 may be, but is not limited to, two, three, four, etc. For example, referring to Figure 4 The number of the second adjusting members 40 can be two, and they can be jacks with super strong load capacity, which can better support the annular limiter 200.

[0071] In the above technical solution, there are at least two second adjustment members 40, which form a stable support mechanism, preventing the risk of deflection of the annular limiter 200 and improving the vertical support stability of the annular limiter 200. Furthermore, the gravitational load of the annular limiter 200 is evenly distributed to the movable member 20, avoiding local deformation caused by single-point force. The second adjustment members 40 are vertically adjustable lifting members, each of which can be raised and lowered independently, allowing local adjustment for uneven deformation of the annular limiter or deviation of the support surface, thereby improving the reliability of the adjustment device 100.

[0072] In some embodiments of the present invention, reference Figures 4 to 7 , third adjusting members 50 are provided at both ends of the moving member 20 in the first direction.

[0073] In the above technical solution, the third adjustment members 50 at both ends of the moving member 20 in the first direction can achieve independent or coordinated adjustment at both ends, allowing for precise calibration of the position of the moving member 20 in the first direction and improving the adjustment efficiency of the third adjustment member 50. Furthermore, the provision of the third adjustment members 50 at both ends can achieve a more uniform force distribution on the moving member 20 in the first direction, reducing the pressure and combination of adjustments at each end, thereby reducing the difficulty of adjustment and improving adjustment efficiency.

[0074] In some embodiments of the present invention, reference Figures 4 to 7 The third adjusting member 50 includes a first connecting seat 51, a second connecting seat 52 and a driving member 53. The first connecting seat 51 is arranged on the base 10, the second connecting seat 52 is arranged on the movable member 20, and the second connecting seat 52 is connected to the first connecting seat 51 through the driving member 53. The driving member 53 can drive the second connecting seat 52 to move relative to the first connecting seat 51 along the first direction.

[0075] It is understood that the first connecting seat 51 and the second connecting seat 52 may be plate-shaped components, block-shaped components, etc., and may be made of, but not limited to, steel, aluminum alloy, fiber-reinforced composite materials, etc. The first connecting seat 51 and the second connecting seat 52 may be connected to the base 10 by, but not limited to, welding, bolting, riveting, etc.

[0076] The driving member 53 may be, but is not limited to, a bolt, a screw, a jackscrew, an electric screw drive, a hydraulic cylinder or a pneumatic drive, etc. For example, referring to Figure 4The driving member 53 is an adjusting bolt, which has a simple structure, is easy to operate and saves costs. The adjusting bolt can control the adjustment accuracy by the number of rotations. For example, each rotation of the adjusting bolt can drive the moving member 20 to move 1 mm along the first direction.

[0077] In the above technical solution, the structure of the first connecting seat 51, the second connecting seat 52 and the driving member 53 is adopted. The structure of the third adjusting member 50 is relatively simple, easy to manufacture, and has high working reliability. It can avoid deformation of the third adjusting member 50 during operation, ensure the reliability of the adjustment accuracy of the adjustment device 100, and is also conducive to extending the service life.

[0078] In some embodiments of the present invention, reference Figures 4 to 7 The movable member 20 is in the shape of a flat plate extending along the first direction. The base 10 is provided with two groups of guide columns 101. The two groups of guide columns 101 are arranged at intervals along the second direction. The guide columns 101 of each group are set to be multiple along the first direction, wherein the second direction is perpendicular to the first direction and the vertical direction, and the movable member 20 is arranged between the two groups of guide columns 101.

[0079] It can be understood that the movable part 20 is in the shape of a flat plate and has a smaller size in the vertical direction, which is beneficial to reducing the height of the entire adjusting device 100, adapting to the narrow space below the annular limiter 200, reducing weight, and facilitating the movement, installation or disassembly of the adjusting device 100.

[0080] The guide column 101 can be, but is not limited to, a bolt, a pin, etc. For example, referring to Figure 4 The guide posts 101 can be bolts, which simplify the structure, save materials, reduce the weight of the adjustment device 100, and lower costs. The number of guide posts 101 in the two groups can be the same or different. When the number of guide posts 101 in the two groups is the same, they can be arranged in the same or different directions in the first direction. The number of guide posts 101 in each group can be, but is not limited to, two, three, four, etc.

[0081] In the above technical solution, two groups of guide posts 101 are arranged at intervals along the second direction to provide guidance for the movement of the movable member 20. The use of two groups of guide posts 101 as a guide structure is simple in structure and reliable, which is conducive to improving the reliability of the adjustment device 100. Each group of guide posts 101 is provided with multiple guide posts 101 along the direction of movement to form a linear support array, which distributes the load of the movable member 20 to each guide post 101, avoiding bending of the guide posts 101 caused by single-point overload. The multi-post support can also reduce stress, further improving the reliability of the adjustment device 100.

[0082] In some embodiments of the present invention, reference Figures 5 to 8The adjusting device 100 also includes a gasket 60, which is arranged between the moving part 20 and the base 10. The gasket 60 includes a copper base 61 and a plating 62 coated on the copper base 61. The first connecting seat 51 and the two sets of guide columns 101 both stop at the edge of the gasket 60 to limit the gasket 60.

[0083] The plating layer 62 may be, but is not limited to, nickel plating, chrome plating, or PTFE plating.

[0084] In the above technical solution, the gasket 60 is arranged between the movable part 20 and the base 10, which can reduce the friction of the movable part 20, facilitate the movable part 20 to move in the first direction, and improve the reliability of the movable part 20. The gasket 60 comprises a copper substrate 61 and a coating 62 coated on the copper substrate 61. Copper has good ductility and strength. As a substrate, it can support the load between the movable part 20 and the base 10, and avoid the gasket 60 from being deformed by stress and causing the adjustment accuracy to decrease. The coating 62 can improve the wear resistance, corrosion resistance and friction reduction performance of the gasket 60, and improve the reliability of the gasket 60. The gasket 60 adopting the above structure can also avoid the movable part 20 and the base 10 from contacting and generating debris, can reduce the risk of material contamination, and ensure that the installation environment of the Dewar base remains in the expected clean conditions.

[0085] The first connecting seat 51 and the two sets of guide columns 101 are both stopped against the edge of the gasket 60, so the gasket 60 can be limited in the first direction and the second direction to prevent the gasket 60 from moving, ensuring that the moving part 20 always moves on the gasket 60, and improving the reliability of the adjustment device 100.
