[0025] Next, refer to Figures 1 - 10 to describe the transfer device 100 of the embodiments of the present invention.

[0026] As Figures 1 to 4As shown, the transfer device 100 according to an embodiment of the present invention can be applied to transfer the cryostat base 200 of a nuclear fusion device. The cryostat base 200 includes a skirt section 210 and a base head 220. The transfer device 100 includes: a support base 10, a support mechanism 20, and a moving mechanism 30.

[0027] There are multiple support bases 10. The support mechanism 20 may include a bracket 21, and a plurality of first support units 211 and a plurality of second support units 212 provided on the bracket 21. The bracket 21 is placed on the multiple support bases 10. The plurality of first support units 211 are arranged at intervals in the circumferential direction, and are adjustable in height in the vertical direction and are used to support the skirt section 210. The plurality of second support units 212 are arranged at intervals in the circumferential direction, and are adjustable in height in the vertical direction and are used to support the base head 220; the moving mechanism 30 is provided below the bracket 21 and is vertically liftable.

[0028] The support base 10 can be a mechanism for supporting the support mechanism 20, and can be understood as components such as piers and legs. The number of support bases 10 can be, but is not limited to, two, four, six, eight, ten, twelve, fourteen, sixteen, eighteen, twenty, twenty-two, twenty-four, etc. For example, referring to Figure 9 , the number of support bases 10 can be twenty-four.

[0029] The support mechanism 20 can refer to a mechanism for supporting the cryostat base 200, and the inner contour of the support mechanism 20 is similar to the outer contour of the cryostat base 200. The support mechanism 20 can be, but is not limited to, alloy steel, stainless steel, aluminum alloy, composite materials, etc. In the above solution, the support mechanism 20 may include a bracket 21. The bracket 21 can be a plate-like structure, and the shape can be, but is limited to, circular, polygonal, irregular, etc. For example, referring to Figure 4 , when it is polygonal, it can be an octagon, which is similar to a circle, can save materials, and can also reduce processing costs.

[0030] The first support unit 211 can refer to a mechanism for supporting the skirt section 210, and the number can be, but is not limited to, two, four, six, eight, ten, twelve, fourteen, sixteen, eighteen, twenty, twenty-two, twenty-four, etc. Referring to Figure 3 , the "vertical direction" can refer to the up and down direction. There is a certain distance between the first support units 211, which can evenly bear the weight of the skirt section 210 and avoid structural deformation caused by local stress concentration. Since the height of each first support unit 211 is adjustable in the vertical direction, the plurality of first support units 211 can support and adjust from multiple positions, so that the skirt section 210 can be adjusted to a horizontal state.

[0031] The second support unit 212 can refer to the mechanism that supports the base head 220, and the number can be, but is not limited to, two, four, six, eight, ten, twelve, fourteen, sixteen, eighteen, twenty, twenty-two, twenty-four, etc. There is a certain distance between the second support units 212, which can evenly bear the weight of the base head 220 and avoid structural deformation caused by local stress concentration. Since the height of each second support unit 212 is adjustable in the vertical direction, multiple second support units 212 can support and adjust from multiple positions, so that the base head 220 can be adjusted to a horizontal state.

[0032] Among them, multiple first support units 211 can be formed into a first annular structure at intervals in the circumferential direction, multiple second support units 212 can be formed into a second annular structure at intervals in the circumferential direction, the second annular structure and the first annular structure can be concentric, and the second annular structure is located inside the first annular structure.

[0033] The moving mechanism 30 can refer to a mechanism that can move and can also adjust the position of the bracket 21 in the up and down direction. When the bracket 21 is placed on multiple support seats 10, since the moving mechanism 30 can be lifted and lowered in the vertical direction, the moving mechanism 30 can move to the lower side of the bracket 21 at a lower height and lift the entire bracket 21 and the Dewar base 200 after rising. Thus, the bracket 21 can be separated from the support seats 10, and the moving mechanism 30 can carry the support mechanism 20 to transport the Dewar base 200. When reaching the target position, multiple support seats 10 can be rearranged, and the moving mechanism 30 can descend a certain height so that the bracket 21 can be supported on multiple support seats 10 again to temporarily place the Dewar base 200.

[0034] For the transfer device 100 according to the embodiment of the present invention, the first support unit 211 and the second support unit 212 can respectively adjust the heights of the skirt section 210 and the base head 220 in the vertical direction and fix the Dewar base 200, which can prevent the skirt section 210 and the base head 220 from deforming, and can also make the skirt section 210 and the base head 220 in a horizontal state, avoiding offset and tilt of the Dewar base 200 during the transfer process and improving the accuracy of the Dewar base 200 in the horizontal direction. The moving mechanism 30 can adjust the height of the bracket 21 in the vertical direction, can make the bracket 21 in a horizontal state, and perform secondary adjustment on the Dewar base 200 in the horizontal direction, further improving the accuracy of the Dewar base 200 in the horizontal direction. It can be understood that the above transfer device 100 can adjust the skirt section 210 and the base head 220 of the Dewar base 200 from multiple aspects and positions, so as to meet the higher requirements for the dynamic load coefficient and the eccentric load coefficient of the Dewar base 200 during the transfer process.

[0036] The skirt support portion 2111 and the flange support portion 2112 are arranged at intervals along the circumferential direction. The skirt support portion 2111 and the flange support portion 2112 can be arranged in the radial direction of the first annular structure surrounded by the plurality of first support units 211, located on the same straight line, or staggered in the circumferential direction of the first annular structure. Figure 4 The skirt support portion 2111 and the flange support portion 2112 are arranged at intervals on the same straight line.

[0037] In the above technical solution, through the multiple flange support parts 2112 and multiple skirt support parts 2111 arranged at intervals along the circumference, the height of the flange support part 2112 is less than the height of the skirt support part 2111, which can adapt to the shape of the Dewar base 200, evenly bear the weight of the skirt 2101 and the lower plane flange 2102, effectively reduce the risk of deformation of the skirt 2101 and the lower plane flange 2102, further improve the support effect of the first support unit 211 on the skirt section 210, reduce the risk of deformation of the Dewar base 200 during transportation, and improve the reliability of the transportation device 100. At the same time, the flange support part 2112 and the skirt support part 2111 are adjustable in height in the vertical direction, which can ensure that the skirt 2101 and the lower plane flange 2102 are in a horizontal state, and further improve the leveling effect of the Dewar base 200.

[0038] In some embodiments of the present invention, reference Figure 5 and Figure 6, the skirt support portion 2111 includes a first support column 21111, a first support 21112, a first lifting member 21113, and a first bolt assembly 21114.

The first bolt assembly 21114 is movably connected to the first support 21112 and the first support column 21111, and can keep the first support 21112 and the first support column 21111 relatively fixed. The flange support portion 2112 includes a second support column 21121, a second support 21122, a second lifting member 21123, and a second bolt assembly 21124. The second support column 21121 is provided on the bracket 21 and has a height less than that of the first support column 21111. The second lifting member 21123 can move the second support 21122 relative to the second support column 21121 in the vertical direction. The second bolt assembly 21124 is movably connected to the second support 21122 and the second support column 21121, and can keep the second support 21122 and the second support column 21121 relatively fixed.

[0039] The first lifting member 21113 can be a mechanism that enables the vertical displacement of the first support 21112 to be adjustable, and can be, but is not limited to, a jack, a hydraulic cylinder, a lead screw, etc. For example, referring to Figure 5 , the first lifting member 21113 can be a jack.

[0040] The first bolt assembly 21114 can be a mechanism connecting the first support 21112 and the first support column 21111, and can be composed of gaskets, bolts, and nuts. Referring to Figure 5 , the bolt is connected to the first support 21112. The first support column 21111 is provided with a through hole in the vertical direction, and coaxially arranged gaskets are provided at both ends of the through hole. A plurality of nuts can be sleeved on the bolt, then passed through the through hole on the first support column 21111, and the bolt is tightened with nuts. Among them, the number of nuts at both ends of the through hole where the bolt is located can be the same or different. After the first lifting member 21113 adjusts the height of the first support 21112 relative to the first support column 21111, the nuts at both ends of the through hole where the bolt is located in the first bolt assembly 21114 can be locked, thereby keeping the relative position of the first support 21112 and the first support column 21111 fixed. In the skirt support portion 2111 with the above structure, both the first bolt assembly 21114 and the first lifting member 21113 can be adjusted, so that two adjustments can be achieved.

[0041] The second lifting member 21123 can be a mechanism that enables the vertical displacement of the second support 21122 to be adjustable, and can be, but is not limited to, a jack, a hydraulic cylinder, a lead screw, etc.

[0042] The second bolt assembly 21124 may refer to the mechanism connecting the second support 21122 and the second support column 21121, which may be composed of gaskets, bolts, and nuts.

A nut can be sleeved on the bolt, then passed through the through hole on the second support column 21121, and the bolt can be tightened with a nut. Among them, the number of nuts at both ends of the through hole where the bolt is located in the second bolt assembly 21124 can be the same or different. After the second lifting member 21123 adjusts the height of the second support 21122 relative to the second support column 21121, the nuts at both ends of the through hole where the bolt is located in the second bolt assembly 21124 can be locked, thereby keeping the relative position of the second support 21122 and the second support column 21121 fixed. In the flange support portion 2112 with the above structure, both the second bolt assembly 21124 and the second lifting member 21123 can be adjusted, thereby enabling two adjustments.

The structures of the skirt support portion 2111 and the flange support portion 2112 are simple, which can save costs and improve the reliability of the transfer device 100. At the same time, it can also facilitate the adjustment of the displacement of the first support 21112 and the second support 21122 in the vertical direction, and improve the efficiency of the transfer dewar base 200.

The bottom support portion 2121 and the edge support portion 2122 may also be distributed in the radial direction of the second annular structure and located on the same straight line. For example, referring to Figure 4 , the bottom support portion 2121 and the edge support portion 2122 are not on the same straight line and are arranged at intervals from each other.

[0046] In the above technical solution, by means of a plurality of bottom support portions 2121 and a plurality of edge support portions 2122 arranged at intervals in the circumferential direction, the bottom 2201 of the head and the edge 2202 of the head can be supported, the risk of deformation of the bottom 2201 of the head and the edge 2202 of the head during the transfer process can be reduced, the risk of the Dewar base 200 shifting during the transfer process can be ensured, and the weights of the bottom 2201 of the head and the edge 2202 of the head can be evenly borne, reducing the risk of deformation of the Dewar base 200 during the transfer process and improving the reliability of the transfer device 100. At the same time, the heights of the bottom support portion 2121 and the edge support portion 2122 are adjustable in the vertical direction, which can ensure that the bottom 2201 of the head and the edge 2202 of the head are in a horizontal state, guarantee the accuracy of the bottom 2201 of the head and the edge 2202 of the head in the horizontal direction, and further improve the leveling effect on the Dewar base 200.

[0047] In some embodiments of the present invention, referring to Figure 7 and Figure 8 , the bottom support portion 2121 includes a third support column 21211, a third support 21212, a third lifting member 21213 and a third bolt assembly 21214. The third support column 21211 is provided on the bracket 21. The third lifting member 21213 can make the third support 21212 move relative to the third support column 21211 in the vertical direction. The third bolt assembly 21214 is movably connected to the third support 21212 and the third support column 21211 and can keep the third support 21212 and the third support column 21211 relatively fixed. The edge support portion 2122 includes a fourth support column 21221, a fourth support 21222, a fourth lifting member 21223 and a fourth bolt assembly 21224. The fourth support column 21221 is provided on the bracket 21. The fourth lifting member 21223 can make the fourth support 21222 move relative to the fourth support column 21221 in the vertical direction. The fourth bolt assembly 21224 is movably connected to the fourth support 21222 and the fourth support column 21221 and can keep the fourth support 21222 and the fourth support column 21221 relatively fixed.

[0048] The third lifting member 21213 may be a mechanism that enables the vertical displacement of the third support 21212 to be adjustable, and may be, but is not limited to, a jack, a hydraulic cylinder, a lead screw, etc. For example, referring toFigure 5 The third lifting member 21213 can be a jack.

[0049] The third bolt assembly 21214 can refer to the mechanism connecting the third support 21212 and the third pillar 21211, which can be composed of gaskets, bolts, and nuts. Refer to Figure 7 , the bolt is connected to the third support 21212, the third pillar 21211 is provided with a through hole in the vertical direction, and coaxial gaskets are provided at both ends of the through hole. Multiple nuts can be sleeved on the bolt, then passed through the through hole on the third pillar 21211, and the bolt is tightened with nuts. Among them, the number of nuts at both ends of the through hole where the bolt is located can be the same or different. After the third lifting member 21213 adjusts the height of the third support 21212 relative to the third pillar 21211, the nuts at both ends of the through hole where the bolt is located in the third bolt assembly 21214 can be locked, thereby keeping the relative position of the third support 21212 and the third pillar 21211 fixed. In the bottom support part 2121 with the above structure, both the third bolt assembly 21214 and the third lifting member 21213 can be adjusted, thereby enabling two adjustments.

[0050] The fourth lifting member 21223 can be a mechanism that enables the displacement of the fourth support 21222 in the vertical direction to be adjustable, and can be, but is not limited to, a jack, a hydraulic cylinder, a lead screw, etc.

Refer to Figure 6 , the bolt is connected to the fourth support 21222, the fourth pillar 21221 is provided with a through hole in the vertical direction, and coaxial gaskets are provided at both ends of the through hole. Multiple nuts can be sleeved on the bolt, then passed through the through hole on the fourth pillar 21221, and the bolt is tightened with nuts. Among them, the number of nuts at both ends of the through hole where the bolt is located can be the same or different. After the fourth lifting member 21223 adjusts the height of the fourth support 21222 relative to the fourth pillar 21221, the nuts at both ends of the through hole where the bolt is located in the fourth bolt assembly 21224 can be locked, thereby keeping the relative position of the fourth support 21222 and the fourth pillar 21221 fixed. In the edge support part 2122 with the above structure, both the fourth bolt assembly 21224 and the fourth lifting member 21223 can be adjusted, thereby enabling two adjustments.

[0052] In the above technical solution, the bottom support portion 2121 includes a third pillar 21211, a third support 21212, a third lifting member 21213, and a third bolt assembly 21214, and the edge support portion 2122 includes a fourth pillar 21221, a fourth support 21222, a fourth lifting member 21223, and a fourth bolt assembly 21224. The structures of the bottom support portion 2121 and the edge support portion 2122 are simple, which can save costs and improve the reliability of the transfer device 100. At the same time, it is also convenient to adjust the displacements of the third support 21212 and the fourth support 21222 in the vertical direction, improving the efficiency of the transfer Dewar base 200.

[0053] In some embodiments of the present invention, referring to Figure 7 and Figure 8 , the third support 21212 is provided with a first profiling support surface 2121a, and the first profiling support surface 2121a matches the shape of the bottom surface of the head bottom 2201; the fourth support 21222 is provided with a second profiling support surface 2122a, and the second profiling support surface 2122a matches the shape of the outer surface of the head edge 2202.

[0055] The second profiling support surface 2122a may refer to a profiling surface that can be fully attached to the head edge 2202, and may be, but not limited to, a spherical surface, a conical surface, or a specific curved surface, etc.

[0056] In the above technical solution, the first profiling support surface 2121a is fully attached to the bottom surface of the head bottom 2201, achieving surface contact instead of point contact, avoiding local stress concentration, and preventing the head bottom 2201 from deforming. The second profiling support surface 2122a is fully attached to the head edge 2202, achieving surface contact instead of point contact, avoiding local stress concentration, and preventing the head edge 2202 from deforming. Together with the first profiling support surface 2121a, they form a three-dimensional support system of "bottom lifting + lateral constraint", ensuring the stability of the Dewar base 200 during transportation and improving the reliability of the transfer device 100.

[0057] In some embodiments of the present invention, referring to Figures 5 to 8 , the first support 21112, the second support 21122, the third support 21212, and the fourth support 21222 are all provided with barrier gaskets 21101.

[0058] The barrier gasket 21101 can be made of, but not limited to, materials such as bakelite, rubber, fiberglass resin, ceramics, polytetrafluoroethylene, etc. In the above technical solution, the barrier gasket 21101 can block the electrochemical corrosion between the support mechanism 20 and the Dewar base 200 and play an insulating and protective role, and can also avoid impurity contamination caused by metal contact between the support mechanism 20 and the Dewar base 200, such as material contamination, which can improve the reliability of the transfer device 100.

[0059] In some embodiments of the present invention, referring to Figure 9 , a plurality of support seats 10 are divided into a first group 11, a second group 12, and a third group 13. The first group 11, the second group 12, and the third group 13 are arranged at intervals in the first direction. A first aisle 14 is formed between the first group 11 and the second group 12, and a second aisle 15 is formed between the second group 12 and the third group 13. The first group 11, the second group 12, and the third group 13 each include at least two support seats 10. The first aisle 14 and the second aisle 15 extend in the second direction, and the second direction is perpendicular to the first direction; there are two moving mechanisms 30. The two moving mechanisms 30 extend in the second direction, and one is arranged in the first aisle 14 and the other is arranged in the second aisle 15.

[0060] The "first direction" can refer to Figure 9 the left - right direction. The dimensions of the first aisle 14 and the second aisle 15 in the first direction are greater than the dimensions of the moving mechanism 30 in the first direction. The "second direction" can refer to Figure 9 the front - back direction. Among them, the first aisle 14 and the second aisle 15 can refer to Figure 9 the dashed - line frames in

[0061] The number of the first group 11 can be, but not limited to, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, etc. The number of the second group 12 can be, but not limited to, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, etc. The number of the third group 13 can be, but not limited to, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, etc. For example, referring to Figure 9 , the first group 11 can be seven, the second group 12 can be nine, and the third group 13 can be seven.

[0062] In the above technical solution, the first group 11, the second group 12, and the third group 13 are arranged at intervals along the first direction and include at least two support seats 10, which can form a multi-point load-bearing network to disperse the weight pressure of the Dewar base 200, avoid single-point overload, stably support the Dewar base 200, ensure that the Dewar is hoisted in a horizontal state, and improve the reliability of the transfer device 100. The first aisle 14 and the second aisle 15 extend along the second direction, which can provide access channels for the two moving mechanisms 30. In this way, interference between the moving mechanisms 30 and the multiple support seats 10 during the movement of the moving mechanisms 30 can be avoided, and the multiple moving mechanisms 30 can also have a large support surface, which can better support the entire bracket 21, thereby improving the stability and reliability of the transfer process of the support mechanism 20 and the Dewar base 200.

[0063] In some embodiments of the present invention, referring to Figure 9 , the first group 11, the second group 12, and the third group 13 include at least three support seats 10. The at least three support seats 10 of the first group 11, the second group 12, and the third group 13 are all arranged at intervals along the first direction and the second direction. The number of support seats 10 in the first group 11 and the third group 13 is less than the number of support seats 10 in the second group 12.

[0064] In the above technical solution, the first group 11, the second group 12, and the third group 13 include at least three support seats 10, which can ensure that the first group 11, the second group 12, and the third group 13 are arranged at intervals along the first direction and the second direction. The number of support seats 10 in the first group 11 and the third group 13 is less than the number of support seats 10 in the second group 12, which can make the number of support seats 10 at the central position of the Dewar base 200 relatively large, bear most of the weight of the Dewar base 200, and ensure the stability of the Dewar base 200. At the same time, the number of support seats 10 can also be reduced to save costs.

[0065] In some embodiments of the present invention, referring to Figure 10 , the moving mechanism 30 includes a power head 31, a six-axle modular transport vehicle 32, and two four-axle modular transport vehicles 33. The power head 31, the six-axle modular transport vehicle 32, and the two four-axle modular transport vehicles 33 are arranged along the second direction and are connected in sequence.

[0066] The power head 31 can be a PPU power head. A PPU power head (usually refers to Power Pack Unit Locomotive or Powered Pusher Unit) is a power unit that can work independently or collaboratively, and drives heavy loads to move on tracks, flat ground, or specific routes by providing strong traction or thrust.

[0067] The six-axle modular transporter 32 and the four-axle modular transporter 33 are two special engineering vehicles for transporting super-heavy and large-sized goods. The six-axle modular transporter 32 has all-wheel independent steering, supports lateral translation, in-situ rotation, and serpentine travel, and has a relatively small minimum turning radius. The four-axle modular transporter 33 has lower steering flexibility (usually front-axle steering or limited all-wheel steering) and a relatively large minimum turning radius. Among them, each wheel of the power head 31, the six-axle modular transporter 32, and the four-axle modular transporter 33 can achieve hydraulically adjustable height, and the hydraulic adjustment compensation stroke is 700 mm (i.e., adjustable within the range of ±350 mm). By adjusting the hydraulic compensation height of the tires on each axle, the transporter can be made horizontal on the inclined surface and the vehicle deck surface.

[0068] In the above technical solution, the moving mechanism 30 includes a power head 31, a six-axle modular transporter 32, and two four-axle modular transporters 33 (with a total weight of 610 t during transportation). By increasing the ground bearing area, it can ensure that the bearing capacity of the floor of the prefabrication hall is met when transporting to the floor of the prefabrication hall. The power head 31, as the main driving unit, provides high torque output and intelligent speed regulation (such as frequency conversion control), ensuring smooth start / stop and avoiding load offset caused by inertial impact, thereby improving the reliability of the transfer device 100. The six-axle modular transporter 32 and the four-axle modular transporter 33 can achieve the horizontal state of the moving mechanism 30 on the inclined surface and the vehicle deck surface by adjusting the hydraulic compensation height of the tires on each axle, ensuring the accuracy of the Dewar base 200 in the horizontal direction and improving the reliability of the transfer device 100. At the same time, the six-axle modular transporter 32 is connected to the power head 31 to achieve flexible turning, improving the versatility of the transfer device 100.

[0069] Reference Figure 11 , According to an embodiment of the present invention, a method for transporting a Dewar base 200 is further provided. The Dewar base 200 is applied to a nuclear fusion device and includes the transfer device 100 according to any one of the foregoing. The method includes: Step S1: Place the bracket 21 of the support mechanism 20 on a plurality of support seats 10; The method of placing the bracket 21 of the support mechanism 20 on a plurality of support seats 10 may be, but is not limited to, hoisting, slide rail / guide rail installation, hydraulic / mechanical jacking, robotic arm / automated installation, etc.

[0070] Step S2: Place the Dewar base 200 on the support mechanism 20, such that the skirt section 210 of the Dewar base 200 is supported on a plurality of first support units 211, and the base head 220 is supported on a plurality of second support units 212, and adjust the Dewar base 200 to be horizontal through the plurality of first support units 211 and the plurality of second support units 212; Place the Dewar base 200 on the support mechanism 20. Then, according to the on-site measurement data, adjust the position of the skirt section 210 in the vertical direction through the first support unit 211 to make the skirt section 210 in a horizontal state. Adjust the position of the base head 220 in the vertical direction through the second support unit 212 to make the base head 220 in a horizontal state, and fix the Dewar base 200.

[0071] The method of placing the Dewar base 200 on the support mechanism 20 can be, but is not limited to, hoisting, slide rail / guide installation, hydraulic / mechanical jacking, robotic arm / automated installation, etc.

[0072] Step S3: Move the moving mechanism 30 below the bracket 21, and lift the entire moving mechanism 30 to separate the assembly component composed of the support mechanism 20 and the Dewar base 200 from the plurality of support seats 10; Step S4: Control the moving mechanism 30 to travel along a predetermined trajectory, and real-time monitor the pose state of the Dewar base 200, and adjust the plurality of first support units 211 and the plurality of second support units 212 in real time to keep the Dewar base 200 horizontal; Step S5: Place the plurality of support seats 10 at the target position for transporting the Dewar base 200; Step S6: After the moving mechanism 30 moves to the target position, lower the entire moving mechanism 30 to place the bracket 21 and the Dewar base 200 back on the plurality of support seats 10, and control the moving mechanism 30 to move out from below the bracket 21.

[0073] According to the method for transporting the Dewar base 200 according to the embodiment of the present invention, through the first support unit 211 and the second support unit 212, deformation of the skirt section 210 and the base head 220 of the Dewar base 200 can be avoided, and the accuracy of the skirt section 210 and the base head 220 of the Dewar base 200 in the horizontal direction can also be adjusted. The moving mechanism 30 can perform secondary adjustment on the accuracy of the Dewar base 200 in the horizontal direction to meet the high installation accuracy requirements of the Dewar base 200. Control the moving mechanism 30 to travel along a predetermined trajectory, and real-time monitor the pose state of the Dewar base 200, and adjust the plurality of first support units 211 and the plurality of second support units 212 in real time to keep the Dewar base 200 horizontal, further improving the accuracy of the Dewar base 200 in the horizontal direction. It can be understood that the above-mentioned method for transporting the Dewar base 200 can adjust the skirt section 210 and the base head 220 of the Dewar base 200 from multiple aspects and positions, so as to meet the higher requirements for the dynamic load coefficient and the eccentric load coefficient during the transportation of the Dewar base 200.

[0074] In some embodiments of the present invention, refer to Figure 12, a step of placing the Dewar base 200 on the support mechanism 20, such that the skirt section 210 of the Dewar base 200 is supported on a plurality of first support units 211, and the base head 220 is supported on a plurality of second support units 212, and adjusting the Dewar base 200 to be horizontal by the plurality of first support units 211 and the plurality of second support units 212, includes: Placing the Dewar base 200 on the support mechanism 20; Supporting the skirt portion 2101 of the Dewar base 200 on a plurality of skirt support portions 2111, supporting the lower plane flange 2102 on a plurality of flange support portions 2112, supporting the bottom of the head 2201 on a plurality of bottom support portions 2121, and supporting the edge of the head 2202 on a plurality of edge support portions 2122; Adjusting the Dewar base 200 to be horizontal by the plurality of skirt support portions 2111, the plurality of flange support portions 2112, the plurality of bottom support portions 2121, and the plurality of edge support portions 2122.

[0075] In the above technical solution, the skirt 2101 and the lower plane flange 2102 can be fixed by the flange support portion 2112 and the bottom support portion 2121, and the precision of the skirt 2101 and the lower plane flange 2102 in the horizontal direction can also be adjusted. The bottom of the head 2201 and the edge of the head 2202 can be fixed by the bottom support portion 2121 and the edge support portion 2122, and the precision of the bottom of the head 2201 and the edge of the head 2202 in the horizontal direction can also be adjusted, further improving the precision of the Dewar base 200 in the horizontal direction.

[0076] In some embodiments of the present invention, before the step of placing the bracket 21 of the support mechanism 20 on a plurality of support seats 10, the method includes: optionally adding gaskets on the plurality of support seats 10 to adjust the bracket 21 to be horizontal by the plurality of support seats 10.

[0077] In the above technical solution, the gaskets can compensate for the unevenness between the support seats 10 and the installation surface, ensure the precision of the support seats 10 in the horizontal direction, and improve the reliability of the transfer device 100.
