Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0061] like Figure 1 , Figure 6 and Fig.12As shown, the embodiment provides a superconducting acceleration module transportation system (hereinafter referred to as transportation system 1000), which can fix the superconducting acceleration module 2000 in the compartment of the transportation vehicle when transporting the superconducting acceleration module 2000. The superconducting acceleration module 2000 may include a vacuum tube 2100 and a cold mass structure 2200, and the cold mass structure 2200 may be arranged in the vacuum tube 2100.

[0062] like Figure 1 , Figure 4 and Fig.12 As shown, in some embodiments, the transport system 1000 may include a mounting frame 100, an adapter frame 200, and a plurality of vibration isolators 300. The adapter frame 200 may be disposed in the mounting frame 100 and may be disposed close to one side of the mounting frame 100. The plurality of vibration isolators 300 may be disposed around the circumference of the adapter frame 200 and connected between the adapter frame 200 and the mounting frame 100.

[0063] During use, the mounting frame 100 can be fixedly installed in the carriage by welding or bolting. The superconducting acceleration module 2000 can be accommodated in the mounting frame 100 and fixedly installed on the adapter frame 200. The vibration isolator 300 can be used to achieve vibration isolation between the mounting frame 100 and the adapter frame 200. When the mounting frame 100 vibrates, the vibration isolator 300 can prevent the vibration from being further transmitted to the superconducting acceleration module 2000 through the adapter frame 200, thereby reducing the impact vibration of the superconducting acceleration module 2000, thereby reducing the probability of damage to the superconducting acceleration module 2000 during transportation.

[0064] like Figure 1 , Figure 2 and Fig.12 As shown, the transport system 1000 also has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. The first direction X may be parallel to the axial direction of the superconducting acceleration module 2000 and the length direction of the transport system 1000. The second direction Y may be parallel to the width direction of the transport system 1000, and the third direction Z may be parallel to the height direction of the transport system 1000.

[0065] In an embodiment, the mounting frame 100 may include a first side 101 and a second side 102 opposite to each other, and the first side 101 and the second side 102 may be distributed along a third direction Z. In some embodiments, the first side 101 may be the bottom of the mounting frame 100 , and the second side 102 may be the top of the mounting frame 100 .

[0066] In some embodiments, the mounting frame 100 may include a truss structure 110, a support frame 120, and a plurality of beams 131. The truss structure 110 may be a substantially rectangular parallelepiped frame structure, and its interior is a hollow structure. The side of the truss structure 110 close to the first side 101 may be a closed structure. The side of the truss structure 110 close to the second side 102 may be configured as an opening 111. The superconducting acceleration module 2000 may be installed in the truss structure 110 through the opening 111.

[0067] In some embodiments, the support frame 120 may be disposed in the truss structure 110 and disposed near the first side 101. The support frame 120 may be fixedly connected to the truss structure 110 by welding or bolting. In some embodiments, the support frame 120 may be substantially a rectangular frame structure, and a cross bar parallel to the second direction Y is disposed inside the support frame 120 to improve the structural strength of the support frame 120.

[0068] In some embodiments, the beam 131 may be parallel to the second direction Y. The beam 131 is connected to a side of the truss structure 110 close to the second side 102 , and a plurality of beams 131 may be sequentially spaced apart along the first direction X. Thus, the overall structural strength of the mounting frame 100 may be further improved.

[0069] like Figures 1 to 3 , Fig.12 In some embodiments, the crossbeam 131 can be detachably connected to the truss structure 110 by bolt connection or other methods. When the superconducting acceleration module 2000 is installed on the transportation system 1000 or the superconducting acceleration module 2000 is removed from the transportation system 1000, the crossbeam 131 can be removed from the truss structure 110 to open the opening 111 at the top of the truss structure 110 so that the superconducting acceleration module 2000 can pass smoothly.

[0070] In some embodiments, the plurality of cross beams 131 may be connected by longitudinal beams 132, and the longitudinal beams 132 may be fixedly connected to the cross beams 131 by welding or bolting. Thus, the plurality of cross beams 131 may form a whole. On the one hand, the structural strength of the mounting frame 100 as a whole may be further improved. On the other hand, the cross beams 131 may be easily disassembled and assembled, thereby improving the disassembly and assembly efficiency.

[0071] like Figures 1 to 5 , Fig.12As shown, in some embodiments, the adapter frame 200 can be floated on the side of the support frame 120 facing the crossbeam 131 through the vibration isolator 300. Among them, the adapter frame 200 as a whole can be presented as a rectangular frame structure. The interior of the adapter frame 200 can be configured with multiple groups of skeletons 210, and each group of skeletons 210 has multiple intersecting skeletons 210, and cooperate to form a honeycomb structure. Correspondingly, a plurality of honeycomb structures connected in sequence can be formed inside the adapter frame 200. Thereby, the structural strength of the adapter frame 200 itself can be improved, and the load-bearing capacity can be improved. Furthermore, the structural strength and load capacity of the transportation system 1000 can also be improved. At the same time, the overall weight of the transportation system 1000 can also be reduced, and the load of the transportation vehicle can be reduced.

[0072] In some embodiments, a plurality of second connection seats 420 are disposed around the circumference of the adapter frame 200 . The second connection seats 420 can be fixedly connected to the adapter frame 200 by welding or bolting, and the second connection seats 420 can face the support frame 120 .

[0073] In the embodiment, a plurality of first connection seats 410 are fixedly connected to one side of the support frame 120 facing the adapter frame 200, and the plurality of first connection seats 410 correspond to the plurality of second connection seats 420. The first connection seats 410 can also be fixedly connected to the support frame 120 by welding or bolting.

[0074] In some embodiments, the vibration isolator 300 may be wound by a steel wire rope, and the vibration isolator 300 may include a plurality of elastic spiral structures 310 connected end to end in sequence, that is, the vibration isolator 300 may be a spring structure. A plurality of vibration isolators 300 may be connected between a plurality of groups of first connection seats 410 and second connection seats 420 in a one-to-one correspondence. The same vibration isolator 300 may be interlaced and arranged between the first connection seats 410 and the second connection seats 420 in sequence. Thus, when the mounting frame 100 is subjected to vibration, the vibration transmitted from the mounting frame 100 to the adapter frame 200 may be absorbed by the vibration isolator 300, thereby reducing the vibration to which the adapter frame 200 is subjected, thereby reducing the vibration to which the superconducting acceleration module 2000 is subjected, and reducing the probability of damage to the superconducting acceleration module 2000.

[0075] In some embodiments, the adapter frame 200 is further fixedly connected to one side away from the support frame 120 with two fixing seats 430, and the two fixing seats 430 can be respectively arranged at two ends of the adapter frame 200 along the first direction X. The fixing seat 430 can be roughly U-shaped, and the open end of the fixing seat 430 can be arranged away from the adapter frame 200. In an embodiment, the fixing seat 430 can be fixedly connected to the adapter frame 200 by bolt connection or welding. The vacuum tube 2100 of the superconducting acceleration module 2000 can be fixedly connected to the fixing seat 430 by bolt connection or the like.

[0076] In other embodiments, three, four, six or more fixing seats 430 may be disposed on the side of the adapter frame 200 away from the support frame 120. The fixing seats 430 may be arranged in sequence along the first direction X.

[0077] like Figure 1 , Figure 6 and Fig.12 As shown, in some embodiments, the transportation system 1000 further includes two sets of relatively arranged end cap structures 500. The two sets of end cap structures 500 can be arranged at two ends of the axial direction of the superconducting acceleration module 2000. The end cap structure 500 can be fixedly connected between the vacuum tube 2100 of the superconducting acceleration module 2000 and the helium return pipe 2210 of the cold mass structure 2200, so that the vacuum tube 2100 and the helium return pipe 2210 can be relatively fixed, thereby reducing the probability of damage to the superconducting acceleration module 2000 during transportation.

[0078] like Figures 6 to 8 As shown, in some embodiments, the sealing head structure 500 may include a sealing cover 530, a driving assembly 520 and a tightening sleeve 510. The sealing cover 530 may be disposed on the open end of the vacuum tube 2100 and may be detachably connected to the vacuum tube 2100 by bolt connection or the like.

[0079] In an embodiment, the expansion sleeve 510 may be inserted into the helium return pipe 2210. One end of the drive assembly 520 may be connected to the sealing cover 530, and the other end of the drive assembly 520 may be transmission-connected to the expansion sleeve 510. The expansion sleeve 510 may include at least two independently arranged expansion parts 511. The expansion part 511 may be in a half-tile shape, and at least two expansion parts 511 may be arranged around the circumference of the drive assembly 520. In an embodiment, the drive assembly 520 may be used to drive at least two expansion parts 511 away from each other, and make the side of the expansion part 511 away from the drive assembly 520 tightly abut against the inner wall of the helium return pipe 2210 to achieve relative fixation. Thereby, the helium return pipe 2210 and the vacuum tube 2100 can be relatively fixed.

[0080] In some embodiments, the expansion sleeve 510 may include two expansion parts 511 disposed opposite to each other. The driving assembly 520 may include a shaft sleeve 521 , a transmission shaft 522 , a support seat 523 , an adjustment nut 524 , an adapter sleeve 525 and a spring washer 526 .

[0081] In other embodiments, the expansion sleeve 510 may include three, four, or other numbers of expansion parts 511 .

[0082] In the embodiment, one end of the transmission shaft 522 can be inserted into the expansion sleeve 510. The support seat 523 can be sleeved between the transmission shaft 522 and the expansion sleeve 510. In some embodiments, the transmission shaft 522 is provided with a first conical surface 5221 on the side facing the support seat 523. The first conical surface 5221 can be gradually inclined away from the central axis L of the superconducting acceleration module 2000 from one end close to the other set of head structures 500 to one end away from the other set of head structures 500. The support seat 523 is provided with a second conical surface 5231 on the side facing the transmission shaft 522, and the second conical surface 5231 can fit with the first conical surface 5221.

[0083] In the embodiment, the sleeve 521 can be sleeved on the side of the support seat 523 away from the transmission shaft 522, that is, the sleeve 521 can be sleeved between the support seat 523 and the expansion sleeve 510. And the support seat 523 can abut against the inner wall of the sleeve 521 on the side facing the transmission shaft 522. In addition, one end of the sleeve 521 away from the other group of head structures 500 can protrude relative to the expansion sleeve 510, and is provided with a connecting edge 5211 opposite to the expansion sleeve 510, and the connecting edge 5211 can be connected to the expansion sleeve 510 by bolts, and the bolts can be parallel to the first direction X.

[0084] In some embodiments, the sleeve 521 may be provided with a third conical surface 5212 on one side facing the expansion sleeve 510. The third conical surface 5212 may be gradually inclined away from the central axis L of the superconducting acceleration module 2000 from one end close to the other end of the end cap structure 500 to one end away from the other end of the end cap structure 500.

[0085] In some embodiments, the adapter set 525 may include a coaxially arranged adapter sleeve 5251 and a connecting ring 5252. The adapter sleeve 5251 may be inserted into the end of the sealing cover 530 away from the vacuum tube 2100, and the adapter sleeve 5251 may be fixedly connected to the sealing cover 530 by bolt connection or welding. The connecting ring 5252 may be fixedly connected to the end of the adapter sleeve 5251 away from the expansion sleeve 510 by bolt connection. In some embodiments, the inner wall of the connecting ring 5252 may be configured with an internal thread.

[0086] In the embodiment, an outer thread that matches the connecting ring 5252 is disposed on the circumference of one end of the adjusting nut 524. The end of the adjusting nut 524 provided with the outer thread can be inserted into the connecting ring 5252 and screwed with the connecting ring 5252. The end of the transmission shaft 522 away from the support seat 523 can be slidably inserted into the adapter set 525 and the adjusting nut 524. The spring washer 526 can be compressibly arranged between the adjusting nut 524 and the transmission shaft 522. In some embodiments, the side of the adjusting nut 524 facing the transmission shaft 522 is also fixedly connected to the limiting bolt 550, the limiting bolt 550 can be slidably inserted into the transmission shaft 522, the spring washer 526 can be sleeved on the circumference of the limiting bolt 550, and the limiting bolt 550 can provide radial limitation for the spring washer 526.

[0087] When fixing the superconducting acceleration module 2000, the expansion sleeve 510 is inserted into the helium return pipe 2210, and the shaft sleeve 521 and the expansion sleeve 510 are gradually locked by bolts. Under the squeezing action of the third cone surface 5212, the two expansion parts 511 can be gradually opened and tightly abutted against the inner wall of the helium return pipe 2210 to achieve expansion. Subsequently, the adjusting nut 524 can be rotated to gradually push the adjusting nut 524 in the direction close to the superconducting acceleration module 2000. During the movement of the adjusting nut 524, the spring washer 526 can transmit the force of the adjusting nut 524 to the transmission shaft 522, and can transmit the force to the support seat 523 through the transmission shaft 522. Under the cooperation of the first conical surface 5221 and the second conical surface 5231, the support seat 523 can apply a force perpendicular to the axial direction of the superconducting acceleration module 2000 to the sleeve 521, and the force can be transmitted to the expansion sleeve 510, so that the expansion part 511 and the inner wall of the helium return pipe 2210 are further expanded and tightened, reducing the possibility of loosening of the head structure 500 and the helium return pipe 2210. Among them, the adapter sleeve 5251 can also provide a guiding function for the transmission shaft 522 to prevent the transmission shaft 522 from being skewed.

[0088] In other embodiments, the driving assembly 520 may include a sealing cover 530, a shaft sleeve 521 and a tightening sleeve 510. After assembly, the shaft sleeve 521 may abut against a side of the sealing cover 530 facing the inner cavity of the vacuum tube 2100.

[0089] In addition, one end of the sealing cover 530 facing the vacuum tube 2100 can be fixedly connected to the vacuum tube 2100 by bolt connection or the like. Thus, the relative fixation of the helium return gas pipe 2210 and the vacuum tube 2100 can be achieved.

[0090] In some embodiments, the end cap structure 500 further includes an end cap 540, which can be disposed on the side of the adjusting nut 524 away from the transmission shaft 522, and can be fixedly connected to the end of the adapter sleeve 5251 away from the superconducting acceleration module 2000 by bolt connection or the like. Thus, the probability of problems such as air leakage can be reduced.

[0091] In some embodiments, one side of the sealing cover 530 is also fixedly connected to the base 560 by welding or other methods, so that the head structure 500 can be easily and stably placed on a bottom surface or other position.

[0092] like Figure 1 , Figures 9 to 11 As shown, in some embodiments, the transport system 1000 further includes a first clamping assembly 610 and a second clamping assembly 620. The first clamping assembly 610 is provided in two groups and is disposed at both ends of the axial direction of the superconducting acceleration module 2000. The second clamping assembly 620 can be disposed near the axial center of the superconducting acceleration module 2000. In the embodiment, the first clamping assembly 610 and the second clamping assembly 620 cooperate to limit the relative rotation of the cold mass structure 2200 relative to the vacuum tube 2100.

[0093] In some embodiments, the first clamping assembly 610 may include two first clamping members 611 disposed opposite to each other, and the two first clamping members 611 may be spaced apart along the second direction Y. In some embodiments, the first clamping member 611 may be a rod-shaped structure parallel to the first direction X. The two first clamping members 611 may cooperate to form a first clamping groove 613 parallel to the first direction X. The circumferential side of the cold mass structure 2200 may be protrudingly provided with a corresponding tubular structure or a rod-shaped structure, which may be inserted into the first clamping groove 613 and abut against the two first clamping members 611. In an embodiment, the vacuum tube 2100 may be fixedly connected to the first connecting plate 612 on one side of the cold mass structure 2200 by bolt connection, and the two first clamping members 611 may be fixedly connected to the first connecting plate 612 on one side of the cold mass structure 2200 by bolt connection.

[0094] In some other embodiments, the first clamping member 611 may also be a block structure or a plate structure, and the first clamping groove 613 between the two first clamping members 611 is parallel to the first direction X.

[0095] In some embodiments, the second clamping assembly 620 may include a second clamping member 621 and a third clamping member 622. Both the second clamping member 621 and the third clamping member 622 may be rod-shaped structures. The second clamping member 621 may be parallel to the second direction Y, the third clamping member 622 may be tilted relative to the second clamping member 621, and the second clamping member 621 and the third clamping member 622 may cooperate to form a fan-shaped second clamping groove 624. The surrounding side of the cold mass structure 2200 may be protrudingly provided with a relative rod-shaped structure or a tubular structure, and inserted into the second clamping groove 624, and clamped by the second clamping member 621 and the third clamping member 622. In the embodiment, the vacuum tube 2100 may be fixedly connected to the second connecting plate 623 on the side facing the cold mass structure 2200 by bolt connection, and the second clamping member 621 and the third clamping member 622 may be fixedly connected to the side of the second connecting plate 623 facing the cold mass structure 2200 by bolt connection.

[0096] Thus, under the limiting effect of the first clamping assembly 610 and the second clamping assembly 620 , the cold mass structure 2200 can be prevented from rotating relative to the vacuum tube 2100 .
