Description

Technical Field

[0001] The present invention relates to the technical field of magnet support, and more specifically, to a support device for supporting a magnet. Background Art

[0002] In nuclear fusion engineering, magnetically confined controlled nuclear fusion energy is an infinite, clean, and safe new energy source. Currently, the Chinese Fusion Engineering Test Reactor (CFETR) is a major project to verify the feasibility of future commercial fusion reactors. The Chinese Fusion Engineering Test Reactor is the largest fusion test reactor in the world to date. As one of the key systems of the nuclear fusion engineering test reactor, its magnet system needs to conduct cryogenic physical property tests on individual magnets such as superconducting magnets before general engineering assembly to detect whether the technical parameters and performance of the magnets meet the requirements of engineering design.

[0003] The magnet system of the Chinese Fusion Engineering Test Reactor includes toroidal field coil magnets, poloidal field coil magnets, and central solenoid coil magnets. Among them, the toroidal field coil magnet weighs about 600 tons, is about 20.5 meters long, and about 12 meters wide. The support device for cryogenic physical property tests of large superconducting magnets for projects such as CFETR poses engineering challenges. Large superconducting magnets have large structural scales and high overall weight loads. Especially in the cryogenic test environment, the structural cold shrinkage deformation caused by their huge structural volumes brings great difficulties to the engineering design of the support device. The support device for large superconducting magnets in cryogenic physical property tests not only needs sufficient structural strength to ensure the stable and safe operation of superconducting magnets under various working conditions, but also needs to overcome the adverse effects brought by the cold shrinkage deformation of the magnet on the support device in the low-temperature environment and minimize the cryogenic loss of the support device as much as possible.

[0004] Currently, there are few support devices for large superconducting magnets, especially for superconducting magnets with asymmetric structural designs in cryogenic physical property tests. For example, the toroidal field coil cryogenic test support device of JT-60SA (superconducting tokamak fusion reactor) in Japan uses a three-point suspension method to support the superconducting magnet, but the superconducting magnet weighs only 18 tons and the maximum length is only 8.5 meters, making it difficult to support magnets with heavier weights and larger sizes.

For this reason, an object of the present invention is to provide a support device for supporting a magnet, and the support device can be used to support magnets with heavier weights and larger sizes.

[0025] The support device 100 for supporting a magnet according to an embodiment of the present invention will be described below with reference to the drawings. The support device 100 can be used to support the magnet during the cryogenic physical property test of the magnet. Of course, it can also be used to support the magnet during other working processes.

[0026] Refer to Figures 1 - 9 As shown, the support device 100 according to an embodiment of the present invention may include a support base 10, a magnet support plate 20, and a plurality of support members 30.

[0027] Specifically, the support base 10 can be placed on the ground to make the support base 10 fixed, thereby improving the support stability of the support device 100 for the magnet. The magnet support plate 20 is disposed above the support base 10, and the magnet support plate 20 is used to support the magnet. Here, "above" can refer to the upper side of the support base 10 in the up-down direction, or can also refer to the upper side of the support base 10 in a direction at an angle to the up-down direction.

[0028] The upper surface of the magnet support plate 20 can be a horizontal plane, and the magnet is supported on the upper side of the magnet support plate 20 of the multiple support devices 100, so that the pressure on the support device 100 is evenly distributed on the multiple support devices 100 and the multiple support members 30 of the support device 100, and then evenly distributed on each part of the support seat 10, reducing the risk of damage to a single support member 30 due to excessive load, which is conducive to extending the service life of the support device 100. The upper surface of the magnet support plate 20 can be a horizontal plane, which can also make the magnet less likely to tilt or even slide off the magnet support plate 20, and the support device 100 has good support stability for the magnet. The support seat 10 and the magnet support plate 20 can be made of higher strength materials to improve the bearing capacity of the support device 100, so that the support device 100 can support heavier magnets. The upper surface of the magnet support plate 20 can also be an irregular shape, etc.

[0029] A plurality of support members 30 are arranged at intervals between the support seat 10 and the magnet support plate 20, so that the weight of the magnet is transferred to the magnet support plate 20 and then transferred to the support seat 10 through the plurality of support members 30. The overall force of the support device 100 can be adjusted by adjusting the number and arrangement of the plurality of support members 30, so that in the process of using the support device 100 to support the magnet, the pressure of the magnet can be evenly transferred to each support member through the magnet support plate 20, so that each support member 30 can be evenly stressed and the pressure evenly transferred to the support seat 10, which can not only improve the support stability of the support device 100, but also make it less likely that the weight carried by several local support members 30 in the support device 100 is significantly higher than the weight carried by other support members 30, reduce the risk of damage to a single support member 30 due to excessive load, reduce the possibility of damage to the support seat 10 due to excessive local pressure, and help improve the overall bearing capacity of the support device 100, extend the service life of the support member 30 and the support seat 10, and extend the service life of the support device 100.

[0030] For example, in some specific embodiments, Figures 1 - 3 As shown, there are nine support members 30 and the nine support members 30 are symmetrically arranged on a horizontal plane relative to the center line of the support base 10 so that the pressure from the magnet on the magnet support plate 20 can be more evenly transmitted to various locations of the support base 10 .

[0031] The support base 10 has a first connection portion 121 on one side facing the support member 30, and the magnet support plate 20 has a second connection portion 21 on one side facing the support member 30, for example Figure 2 and Figures 4 - 5As shown, the upper side of the support base 10 has a first connection portion 121, and the lower side of the magnet support plate 20 has a second connection portion 21. The support member 30 includes a first mating portion 31 and a second mating portion 33. The first mating portion 31 is movably mated with the first connection portion 121 at least in the horizontal and vertical directions, and the second connection portion 21 is movably mated with the second mating portion 33 at least in the horizontal and vertical directions.

[0032] For example, the movement between the first mating portion 31 and the first connection portion 121 can be relative sliding, relative rotation, relative movement, a combination of rotation and movement, etc., so that the support member 30 and the support base 10 can have relative movement in the horizontal direction, the vertical direction, an inclined direction at a certain angle to the horizontal direction, or other directions. For example, the mating manner between the support member 30 and the support base 10 is in the form of a ball joint with multiple degrees of freedom of rotation. Specifically, for example, there is no connection relationship between the first connection portion 121 and the first mating portion 31 but they only contact each other, or there is a partial connection relationship between the first connection portion 121 and the first mating portion 31 but relative movement between the first connection portion 121 and the first mating portion 31 is allowed.

[0033] For example, the movement between the second mating portion 33 and the second connection portion 21 can be relative sliding, relative rotation, relative movement, a combination of rotation and movement, etc., so that the support member 30 and the magnet support plate 20 can have relative movement in the horizontal direction, the vertical direction, an inclined direction at a certain angle to the horizontal direction, or other directions. For example, the mating manner between the support member 30 and the magnet support plate 20 is in the form of a ball joint with multiple degrees of freedom of rotation. Specifically, for example, there is no connection relationship between the second connection portion 21 and the second mating portion 33 but they only contact each other, or there is a partial connection relationship between the second connection portion 21 and the second mating portion 33 but relative movement between the first connection portion 121 and the first mating portion 31 is allowed.

[0034] The support member 30 and the support base 10 can have relative movement, and the support member 30 and the magnet support plate 20 can have relative movement, so that the magnet support plate 20 and the support base 10 can have relative movement. For example, with the support base 10 fixed differently, the support member 30 can move relative to the support base 10, and the magnet support plate 20 can move relative to the support member 30. During the process of testing the low-temperature physical properties of the magnet, the magnet will shrink in a low-temperature environment, and the magnet support plate 20 can move relative to the support base 10 along with the cold shrinkage of the magnet, so that during the process of the magnet's cold shrinkage, the magnet support plate 20 moves along with the magnet, and relative movement between the magnet and the magnet support plate 20 is not likely to occur.

[0035] Compared with the frictional force generated by the relative movement of the magnet and the magnet support plate 20, the acting force that may be generated by the relative movement of the magnet support plate 20 and the support base 10 is relatively controllable, such as the frictional force between the support member 30 and the magnet support plate 20, and the frictional force between the support member 30 and the support base 10. Therefore, through the movable connection between the magnet support plate 20 and the support base 10, the magnet support plate 20 can move together with the magnet, so that relative movement between the magnet and the magnet support plate 20 is not likely to occur, which is beneficial to significantly reduce the frictional force that may be generated between the magnet and the support device 100.

[0036] Through the support member 30, the magnet support plate 20 can move relative to the support base 10, so that the magnet support plate 20 can move accordingly during the deformation of the magnet, enabling the support device 100 to provide a larger spatial displacement range for the magnet, and enabling the support device 100 to be used to support the magnet in a cryogenic environment with a lower temperature. It is not easy to generate frictional force between the magnet and the magnet support plate 20 to hinder the cold shrinkage deformation of the magnet, wear the magnet and the magnet support plate 20, which is beneficial to reducing the adverse effects of the support device 100 on the magnet test results, making the results of cryogenic physics tests more accurate, improving the stability and reliability of cryogenic physics performance tests, and also extending the service life of the support device 100, effectively solving the adverse effects caused by the structural cold shrinkage deformation of the magnet in the cryogenic environment on the support device 100, and enabling the support device 100 to meet the support requirements of the magnet under cryogenic or even ultra-low temperature conditions.

[0037] During the cryogenic physics performance test, the ground temperature is generally higher than the magnet temperature. Supporting the magnet on the support device 100 and placing the support device 100 on the ground can isolate the magnet and the ground through the support device 100. On the premise that the load-bearing capacity of the support device 100 meets the requirements for supporting the magnet, increasing the height of the support device 100 can increase the distance between the magnet and the ground, effectively reduce the cryogenic loss of the magnet, make the results of cryogenic physics tests more accurate, and is beneficial to improving the reliability of cryogenic physics performance tests.

[0038] The support device 100 has a stable support structure with high mechanical strength. The support device 100 can carry a large superconducting magnet and has reliable structural stability. According to parameters such as the weight and size of different magnets, the number and arrangement form of multiple support devices 100 can be adjusted, such as the relative positions of multiple support devices 100, and the number and arrangement form of multiple support members 30 in each support device 100 can be adjusted, such as the relative positions of multiple support members 30. For example, in parts with a greater magnet weight, the number of corresponding support devices 100 is increased, and the number of support members 30 in the corresponding support device 100 is increased, so that multiple support devices 100 can be used to support various types of magnets with different weights and sizes, without the need to design different support devices 100 for different types of magnets. Therefore, the support device 100 in this application has a wider scope of application and is easy to promote and use.

[0039] For example, in some specific embodiments, by adjusting the number and arrangement form of multiple support devices 100 and multiple support members 30 in each support device 100, multiple support devices 100 can be used to support a large superconducting magnet with a weight exceeding 600 tons. The support device 100 has strong load-bearing capacity and good support stability.

[0040] In addition, each support device 100 in this application includes a support base 10, a magnet support plate 20, and multiple support members 30, with a relatively simple structure and low manufacturing cost.

[0041] According to the support device 100 of the embodiment of the present invention, by adjusting the number and arrangement form of multiple support devices 100 and the number and arrangement form of multiple support members 30 in each support device 100, the load-bearing capacity and support stability of the support device 100 can be increased, and the support member 30 is simultaneously movably connected to both the magnet support plate 20 and the support base 10, enabling the magnet support plate 20 to move with the deformation of the magnet, not easily wearing the magnet, providing a large space displacement range for the magnet, effectively solving the adverse effects of the structural deformation of the large magnet on the support device 100, facilitating the extension of the service life of the support device 100, making the support device 100 not easily deformed or even damaged during the process of supporting the magnet, multiple support devices 100 can be used to support magnets with heavier weights and larger sizes, and the manufacturing cost of the support device 100 is relatively low, which is easy to promote and use.

[0042] In some embodiments of the present invention, such as Figures 2 - 4 and Figure 6 shown, one of the first connection portion 121 and the first mating portion 31 is a first groove, and the other of the first connection portion 121 and the first mating portion 31 at least partially extends into the first groove and is movable within the first groove. The movement here can be a combination of one or more of rotation, sliding, moving, etc. For example Figures 2 - 4 and Figure 6As shown, the first connecting portion 121 is a first groove, and a part of the first mating portion 31 extends into the first groove and is slidable and rotatable within the first groove.

[0043] For ease of understanding, the following takes the first connecting portion 121 being a first groove as an example for explanation. Of course, an embodiment where the first mating portion 31 is a first groove can also be obtained.

[0044] When the magnet is not deformed, the first mating portion 31 and the first groove are not prone to relative movement, and the support stability is good. When the magnet is deformed, the magnet support plate 20 moves relative to the support base 10 together with the magnet, and at least part of the first mating portion 31 moves within the first groove.

[0045] The first mating portion 31 being movable within the first groove can increase the contact area between the first mating portion 31 and the first groove when the sizes of the support base 10 and the support member 30 are fixed. Under the pressure of the magnet, this can reduce the possibility of the first mating portion 31 completely disengaging from the first groove, which is beneficial to improving the support reliability during the process of the support device 100 supporting the magnet. Increasing the contact area between the first mating portion 31 and the first groove can also increase the load-bearing capacity of the support device 100.

[0046] At least part of the first mating portion 31 extends into the first groove and is movable within the first groove, so that the first mating portion 31 and the first groove are always in cooperation. By controlling the shapes, sizes, etc. of the first mating portion 31 and the first groove, the relative movement range between the support member 30 and the support base 10 can be controlled, so that the relative movement range between the support member 30 and the support base 10 is not too small to meet the deformation displacement requirements of the magnet, and the relative movement range between the support member 30 and the support base 10 is not too large to facilitate the subsequent restoration of the support member 30 and the support base 10 to their original positions, that is, the positions of the support member 30 and the support base 10 in the state where the support device 100 does not support the magnet, which is convenient for the support device 100 to perform the next work of supporting the magnet.

[0047] In some embodiments, as Figures 2 - 4 and Figure 6 shown, the surface of the groove wall of the first groove is a concave arc surface, and the first mating portion 31 has a convex arc surface that matches the shape of the concave arc surface. For example, the diameter of the concave arc surface is the same as the diameter of the convex arc surface, so that the concave arc surface and the convex arc surface can completely coincide in the state of no relative movement.

[0048] When the magnet is not deformed, the concave arc surface and the convex arc surface match in shape, making it difficult for the concave arc surface and the convex arc surface to have relative movement. Therefore, the magnet is not prone to movement relative to the support device 100, and the stability of supporting the magnet is better, which is beneficial to improving the stability and reliability of cryogenic physical property testing.

[0049] In the case where the magnet is deformed, the magnet support plate 20 moves relative to the support base 10 together with the magnet, that is, the support member 30 moves relative to the magnet support plate 20 and the support member 30 moves relative to the support base 10. Since the concave arc surface and the convex arc surface are in shape matching, during the process of the support member 30 moving relative to the support base 10, the relative movement between the concave arc surface and the convex arc surface is more stable, and problems such as jamming are not likely to occur, which can reduce the interference to the magnet supported by the support device 100, and the stability of supporting the magnet is better, which is beneficial to improving the stability and reliability of cryogenic physical property testing.

[0050] Therefore, by making the concave arc surface of the first groove match the convex arc surface of the first fitting portion 31, the support stability of the support device 100 for the magnet can be better in both the case where the magnet is deformed and the case where the magnet is not deformed.

[0051] In some embodiments of the present invention, as Figure 2 and Figures 5 - 6 shown, one of the second connecting portion 21 and the second fitting portion 33 is a second groove, and the other of the second connecting portion 21 and the second fitting portion 33 at least partially extends into the second groove and is movable in the second groove. Here, the movement can be a combination of one or more of movements such as rotation, sliding, and translation. For example Figure 2 and Figures 5 - 6 shown, the second connecting portion 21 is a second groove, and a part of the second fitting portion 33 extends into the second groove and is slidable and rotatable in the second groove.

[0052] For ease of understanding, the following takes the second connecting portion 21 as the second groove as an example for explanation. Of course, an embodiment in which the second fitting portion 33 is the second groove can also be obtained.

[0053] In the case where the magnet is not deformed, the second fitting portion 33 and the second groove are not likely to have relative movement, and the support stability is good. In the case where the magnet is deformed, the magnet support plate 20 moves relative to the support base 10 together with the magnet, and at least a part of the second fitting portion 33 moves in the second groove.

[0054] The second fitting portion 33 can move in the second groove, which can increase the contact area between the second fitting portion 33 and the second groove when the sizes of the magnet support plate 20 and the support member 30 are fixed, so as to reduce the possibility of the second fitting portion 33 completely disengaging from the second groove under the pressure of the magnet, which is beneficial to improving the support reliability during the process of the support device 100 supporting the magnet. Increasing the contact area between the second fitting portion 33 and the second groove can also increase the load-bearing capacity of the support device 100.

[0055] At least a part of the second engaging portion 33 extends into the second groove and is movable within the second groove, so that the second engaging portion 33 and the second groove are always engaged. By controlling the shapes, sizes, etc. of the second engaging portion 33 and the second groove, the relative movement range between the support member 30 and the magnet support plate 20 can be controlled, so that the relative movement range between the support member 30 and the magnet support plate 20 is not too small to meet the deformation displacement requirements of the magnet, and the relative movement range between the support member 30 and the magnet support plate 20 is not too large to facilitate the subsequent restoration of the support member 30 and the magnet support plate 20 to their original positions, that is, to the positions of the support member 30 and the magnet support plate 20 in the state where the support device 100 does not support the magnet, which is convenient for the support device 100 to perform the next work of supporting the magnet.

[0056] In some embodiments, such as Figure 2 and Figures 5 - 6 shown, the surface of the groove wall of the second groove is a concave arc surface, and the other of the second connecting portion 21 and the second engaging portion 33 has a convex arc surface that matches the shape of the concave arc surface. For example, the diameter of the concave arc surface is the same as the diameter of the convex arc surface, so that the concave arc surface and the convex arc surface can completely coincide in the state where there is no relative movement.

[0057] In the case where the magnet does not deform, the concave arc surface and the convex arc surface match in shape, so that the concave arc surface and the convex arc surface are not likely to have relative movement, so the magnet is not likely to move relative to the support device 100, and the stability of supporting the magnet is better, which is beneficial to improving the stability and reliability of the cryogenic physical property test.

[0058] In the case where the magnet deforms, the magnet support plate 20 moves relative to the support base 10 together with the magnet, that is, the support member 30 moves relative to the magnet support plate 20 and the support member 30 moves relative to the support base 10. Since the concave arc surface and the convex arc surface match in shape, during the process of the support member 30 moving relative to the magnet support plate 20, the relative movement between the concave arc surface and the convex arc surface is more stable, and problems such as jamming are not likely to occur, which can reduce the interference to the magnet supported by the support device 100, and the stability of supporting the magnet is better, which is beneficial to improving the stability and reliability of the cryogenic physical property test.

[0059] Therefore, by making the concave arc surface of the second groove match the convex arc surface of the second engaging portion 33, the support stability of the support device 100 for the magnet can be better in both the case where the magnet deforms and the case where the magnet does not deform.

[0060] In some embodiments of the present invention, such as Figure 2 and Figure 6As shown, the support member 30 further includes a connecting section 32, and the connecting section 32 is connected between the first mating portion 31 and the second mating portion 33. The shape and size of the connecting section 32 are not limited, and the shape, size, etc. of the connecting section 32 can be adjusted to adjust the distance between the magnet support plate 20 and the support base 10, and further adjust the height of the support device 100, so as to adjust the distance between the magnet and the ground. For example Figures 2 - 6 As shown, on the premise of ensuring that the support member 30 is not easily damaged, increasing the size of the connecting section 32 in the up and down direction to increase the size of the support device 100 in the up and down direction can support the magnet at a relatively high position to increase the distance between the magnet and the ground, which is beneficial to reducing the cryogenic loss of the magnet and maintaining the cryogenic state of the magnet.

[0061] Such as Figure 2 and Figure 7 As shown, the support device 100 further includes a limiting member 40. The limiting member 40 is located between the support base 10 and the magnet support plate 20, and the limiting member 40 cooperates with a plurality of support members 30 to limit the distance between the plurality of support members 30. The limiting member 40 can cooperate with one or more of the first mating portion 31, the connecting section 32, and the second mating portion 33 of the support member 30.

[0062] By limiting the distance between the plurality of support members 30 through the limiting member 40, during the assembly process of the support device 100, the distance between the plurality of first mating portions 31 of the plurality of support members 30 and the distance between the plurality of second mating portions 33 can be limited. After the plurality of first mating portions 31 of the plurality of support members 30 are respectively and correspondingly mated with the plurality of first connecting portions 121 of the support base 10, during the process of respectively and correspondingly mating the plurality of second mating portions 33 of the plurality of support members 30 with the plurality of second connecting portions 21 of the magnet support plate 20, the plurality of second mating portions 33 can quickly and respectively and correspondingly mate with the plurality of second connecting portions 21 of the magnet support plate 20, and even enable the plurality of second mating portions 33 to simultaneously and respectively and correspondingly mate with the plurality of second connecting portions 21, so as to quickly install the magnet support plate 20 on the plurality of support members 30, which is beneficial to improving the assembly efficiency of the support device 100.

[0063] In some embodiments, such as Figure 2 and Figure 6 As shown, the first mating portion 31, the connecting section 32, and the second mating portion 33 define a support member 30 with a non-spherical shape, which can reduce the possibility of jamming of the support member 30 between the first connecting portion 121 and the second connecting portion 21, so as to improve the reliability of the movable connection of the magnet support plate 20 relative to the support base 10. Specifically, such as Figure 2 and Figure 6As shown, the first mating portion 31 and the second mating portion 33 are both hemispherical, and the connecting section 32 is a cylinder, making the support member 30 non-spherical and not easily jammed between the first connecting portion 121 and the second connecting portion 21. Moreover, the support member 30 is an axisymmetric shape, so that the forces on each part of the support member 30 are relatively uniform, reducing the possibility of damage due to excessive local stress on the support member 30, which is beneficial to extending the service life of the support member 30 and thus the service life of the support device 100.

[0064] In some embodiments, such as Figure 2 and Figures 6 - 7 shown, the limiting member 40 has a plurality of limiting holes 41, and the connecting sections 32 of the plurality of support members 30 are inserted and mated with the plurality of limiting holes 41 in a one-to-one correspondence. The limiting member 40 cooperates with the plurality of connecting sections 32 to limit the relative positions of the plurality of support members 30. Therefore, the limiting member 40 is not likely to affect the movable mating between the first mating portion 31 and the first connecting portion 121, and the movable mating between the second mating portion 33 and the second connecting portion 21, which is beneficial to taking into account the limiting function of the limiting member 40 on the plurality of support members 30 and the movable connection of the magnet support plate 20 relative to the support base 10.

[0065] Through the insertion and mating of the limiting holes 41 and the connecting sections 32, the structure of the support device 100 can be simplified. And the insertion operation is simple, and the one-to-one correspondence between the plurality of limiting holes 41 and the plurality of connecting sections 32 can be quickly realized. For example, the limiting member 40 is directly pressed against the plurality of support members 30 so that the support members 30 pass through the corresponding limiting holes 41 to quickly realize the limiting function of the limiting member 40 on the plurality of support members 30, which is beneficial to improving the assembly efficiency of the support device 100.

[0066] In some embodiments, such as Figure 2 and Figures 6 - 7 shown, the connecting section 32 is a cylinder, which is convenient for manufacturing. The first mating portion 31 and the second mating portion 33 are connected to both ends of the connecting section 32 in the length direction (such as the up and down direction shown in Figure 2 and Figure 6 shown). There is a gap between the outer peripheral wall of the connecting section 32 and the hole wall of the limiting hole 41, that is, the connecting section 32 and the limiting hole 41 are in clearance fit, the insertion operation speed is faster, and the assembly efficiency of the support device 100 is higher.

[0067] After the support device 100 is assembled, the limiting member 40 can still cooperate with the support member 30, or the limiting member 40 can be separated from the support member 30.

[0068] For example, in some embodiments where the limiting member 40 still cooperates with the connecting section 32 after the support device 100 is assembled, such as Figure 2As shown, after the support device 100 is assembled, through the clearance fit between the connecting section 32 and the limiting hole 41, the position interference of the limiting member 40 on the support member 30 can be reduced, enabling the support member 30 to move relative to the limiting member 40. And after the part of the outer peripheral wall of the connecting section 32 where the support member 30 moves contacts the hole wall of the limiting hole 41, it can drive the limiting member 40 to move together, so that the support member 30 and the limiting member 40 move relative to the magnet support plate 20 and the support base 10 together, to further increase the movement range of the support member 30, and then increase the movement range of the magnet support plate 20 relative to the support base 10. Therefore, during the deformation of the magnet, the magnet support plate 20 can move relative to the support base 10 through the movement of the support member 30, and the movement range of the magnet support plate 20 relative to the support base 10 is large, which can provide a larger spatial displacement range for the magnet.

[0069] For example, in some embodiments where the limiting member 40 is separated from the support member 30 after the support device 100 is assembled, after the support device 100 is assembled, the limiting constraint of the limiting member 40 on the support member 30 can be removed, so that the limiting member 40 is not likely to affect the movement of the support member 30 during the process of the support device 100 supporting the magnet, and the relative movement range of the magnet support plate 20 and the support base 10 is wider, which can provide a larger spatial displacement range for the magnet.

[0070] In some embodiments of the present invention, as Figures 1 - 2 and Figure 8 shown, the support device 100 further includes a frame body 50 and a fixing member 60, and the frame body 50 is fixed above the support base 10. In this application, the fixed connection method can be one or a combination of bolt connection, riveting, welding, etc., as long as the connection is firm. For example, the frame body 50 and the support base 10 are welded together and the connection is firm.

[0071] The limiting member 40 is located inside the frame body 50, and the fixing member 60 is provided on the frame body 50 and connected to the limiting member 40 to fix the position of the limiting member 40 inside the frame body 50. The fixing member 60 and the limiting member 40 are fixedly connected or detachably connected. The connection method between the fixing member 60 and the frame body 50 can be one or a combination of bolt connection, clamping, etc., and the connection method between the fixing member 60 and the limiting member 40 can be one or a combination of contact pressing, plugging, bolt connection, clamping, etc. The fixing member 60 can be components such as screws and bolts.

[0072] Through the connection between the frame body 50 and the support base 10 and the connection between the fixing member 60 and the frame body 50, the relative position of the fixing member 60 and the support base 10 can be restricted. Since the position of the fixing member 60 is fixed, through the connection between the fixing member 60 and the limiting member 40, the position of the limiting member 40 inside the frame body 50 can be fixed, so as to improve the limiting effect of the limiting member 40 on multiple support members 30 during the assembly process of the support device 100.

[0073] After the support device 100 is assembled, the fixing member 60 can still be connected to the limiting member 40, or the fixing member 60 can be separated from the limiting member 40.

[0074] For example, in some embodiments where the fixing member 60 and the limiting member 40 are detachably connected, as Figure 2 shown, after the support device 100 is assembled, the fixing member 60 can be separated from the limiting member 40 to remove the limitation of the fixing member 60 on the limiting member 40, and further remove the limiting constraint of the limiting member 40 on the support member 30, so that the limiting member 40 is not likely to affect the movement of the support member 30 during the process of the support device 100 supporting the magnet. The relative movement range of the magnet support plate 20 and the support base 10 is wider, and a larger spatial displacement range can be provided for the magnet.

[0075] For example, in some specific embodiments, as Figures 1 - 2 shown, the fixing member 60 and the frame body 50 are bolted. During the assembly process of the support device 100, the fixing member 60 can be bolted to the frame body 50 and then inserted into the frame body 50 to press the limiting member 40 to fix the position of the limiting member 40. After the support device 100 is assembled, the fixing member 60 can be removed from the frame body 50 to remove the limitation on the limiting member 40. After the fixing member 60 is removed, the limiting member 40 can fall to the upper surface of the support base 10, so that the limiting member 40 is separated from the support member 30.

[0076] In some embodiments, as Figure 2 shown, a part of the magnet support plate 20 is located inside the frame body 50, so that the part of the magnet support plate 20 located outside the frame body 50 can be used to support the magnet. The fixing member 60 is arranged on the frame body 50 and connected to the magnet support plate 20 to fix the position of the magnet support plate 20 inside the frame body 50. During the assembly process of the support device 100, the position of the magnet support plate 20 can be restricted by the fixing member 60 with a fixed position, which is beneficial to keep the upper surface of the magnet support plate 20 always horizontal and not prone to shaking. After the support device 100 is assembled, the magnet can be placed above the horizontal upper surface of the magnet support plate 20, so that the magnet is not likely to tilt during the process of placing the magnet. After the magnet is placed, the fixing member 60 can be removed to remove the limitation on the magnet support plate 20, so that the magnet support plate 20 can move with the deformation of the magnet, and it is beneficial to maintain the horizontal state of the upper surface of the magnet and the magnet support plate 20 during the whole process of supporting the magnet, and the support for the magnet is more stable.

[0077] In some embodiments of the present invention, the support device 100 includes a filler, which is located between the limiting member 40 and the support base 10 to support the limiting member 40. By supporting the limiting member 40 with the filler between the limiting member 40 and the support base 10, during the assembly process of the support device 100, it is convenient to place the limiting member 40 at the support member 30, facilitating assembly. It is also beneficial to maintain the limiting effect of the limiting member 40 on the plurality of support members 30, which is conducive to improving the assembly efficiency of the support device 100. The filler can be a hard material or a deformable flexible material such as foam.

[0078] In some embodiments of the present invention, such as Figures 2 - 4 shown, the support base 10 includes a base body 11 and a plurality of support members 12. The base body 11 has a plurality of mounting grooves 111, and the plurality of support members 12 are detachably mounted in the plurality of mounting grooves 111 one by one. The first connecting portion 121 is provided on the support member 12. The connection manner between the base body 11 and the support member 12 can be one or a combination of a plurality of connection manners such as bolt connection and snap connection. For example, Figure 2 shown, the base body 11 and the support member 12 are connected by a fastener 80, and the fastener 80 can be a bolt. The bolts mentioned in this application can be hexagon socket head cap screws, hexagon head bolts or other bolts. For example, the fixing member 60 is a hexagon socket head cap screw, and the fastener 80 is a hexagon head bolt.

[0079] The detachable connection between the base body 11 and the support member 12 makes the structural design of the support member 12 more flexible. For example, a plurality of support members 12 can be designed, and parameters such as the shape and size of the first connecting portion 121 in the plurality of support members 12 can be different. It is possible to replace the support member 12 mounted in the mounting groove 111 to replace the support member 30 with different parameters such as shape and size, which is conducive to improving the bearing capacity and support stability of the support device 100. The base body 11 can be used to improve the overall bearing capacity of the support base 10. For example, a material with higher strength is selected to manufacture the base body 11. The base body 11 and the support member 12 can be made of the same or different materials according to needs, which is conducive to improving the bearing capacity of the support device 100 and reducing the manufacturing cost.

[0080] The detachable connection between the base body 11 and the support member 12 also facilitates the installation, maintenance or partial replacement of the support base 10. For example, when the support member 12 is damaged, the support member 12 can be directly replaced without replacing the entire support base 10, which is convenient for subsequent maintenance and effectively reduces the maintenance cost of the support base 10.

[0081] In some embodiments, such as Figure 2As shown, the projection of the support member 30 on the horizontal plane is located within the support component 12, that is, the area of the projection of the support component 12 on the horizontal plane is larger than the area of the projection of the support member 30 on the horizontal plane, so that the first connecting portion 121 of the support component 12 can fully support the first mating portion 31 of the support member 30, and the first mating portion 31 is not easily separated from the first connecting portion 121, which is beneficial to improving the support stability of the support base 10 for the support member 30, so as to improve the support stability of the overall support device 100 for supporting the magnet.

[0082] In some embodiments of the present invention, as Figure 2 shown, the support device 100 includes a heat-insulating bottom plate 70, and the heat-insulating bottom plate 70 is provided on the side of the support base 10 away from the magnet support plate 20. For example, the heat-insulating bottom plate 70, the seat body 11 and the support component 12 are connected by bolts or other connection means. The heat-insulating bottom plate 70 can be made of a heat-insulating material. For example, the heat-insulating bottom plate 70 is made of a glass fiber and resin composite material.

[0083] The heat-insulating bottom plate 70 is beneficial to isolating the external high-temperature environment such as the temperature of the ground, so as to reduce the heat transferred to the magnet, reduce the low-temperature loss of the magnet, make the results of low-temperature physical tests more accurate, and is beneficial to improving the reliability of low-temperature physical property tests.

[0084] The heat-insulating bottom plate 70 can be fixedly connected to the ground to fixedly connect the support device 100 to the ground, so that during the process of placing the magnet on a plurality of support devices 100 and during the process of a plurality of support devices 100 supporting the magnet, the overall support device 100 is not easily displaced, which can improve the stability of the support device 100 for supporting the magnet, so as to improve the stability of low-temperature physical property tests. Of course, the heat-insulating bottom plate 70 can be detachably fixedly connected to the ground. For example, through one or a combination of connection means such as bolt connection and snap connection, the heat-insulating bottom plate 70 is detachably fixedly connected to the ground, which is convenient for removing the support device 100 from the ground after the low-temperature physical property test of supporting the magnet is completed, so as to store the support device 100, facilitate subsequent recycling, increase the number of available times of the support device 100, and have good economy. For example Figure 2 and Figure 9 shown, bolt holes are provided at the four corners of the heat-insulating bottom plate 70, and the four corners of the heat-insulating bottom plate 70 can be fixedly connected to the ground through bolts to fix the position of the entire support device 100 on the ground, and the bolts of the heat-insulating bottom plate 70 can be removed later to remove the support device 100 from the ground.
