Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0027] The present application will be described below in conjunction with Figures 1 to 7 The present application provides a transfer device for a cryostat.

[0028] As Figures 1 to 7 shown, the present application provides a transfer device for a cryostat, which comprises a bottom bracket 1, a main bracket 2, a damping mechanism, a suspension mechanism and a tensioning mechanism.

[0029] Specifically, the bottom bracket 1 serves as a bottom support and can be supported on the ground or the load-bearing part of a transport vehicle. The bottom bracket 1 can adopt a high-strength and low-deformation welded steel structure.

[0030] The bottom end of the bottom bracket 1 is provided with a connecting piece for connecting with the load-bearing part of the transport vehicle. When the cryostat 4 is transported over a long distance and under multiple road conditions, the connecting piece can be used to connect the bottom bracket 1 with the load-bearing part of the transport vehicle to ensure the relative stability of the bottom bracket 1 and the load-bearing part of the transport vehicle. The connecting piece can be a bolt, a buckle or a clamp.

[0031] The bottom bracket 1 has a transverse direction, a longitudinal direction and a vertical direction, and any two of the transverse direction, the longitudinal direction and the vertical direction of the bottom bracket 1 are perpendicular to each other. The bottom bracket 1 can be rectangular, as Figure 1 and Figure 7 indicated. The length direction of the bottom bracket 1 is the transverse direction of the bottom bracket 1, as indicated by the direction of x in Figure 1 . The width direction of the bottom bracket 1 is the longitudinal direction of the bottom bracket 1, as indicated by the direction of y in Figure 1 . The height direction of the bottom bracket 1 is the vertical direction of the bottom bracket 1, as indicated by the direction of z in Figure 1 . When the bottom bracket 1 is placed in a horizontal plane, the vertical direction of the bottom bracket 1 is arranged in a vertical direction.

[0032] The main bracket 2 is arranged above the bottom bracket 1, and the main bracket 2 has a containing space for containing the cryostat 4. The main bracket 2 has at least an upper end with an opening for the cryostat 4 to enter or exit the containing space.

[0033] The suspension mechanism comprises a suspension support 3, a suspension assembly and a hoisting assembly, the suspension assembly and the hoisting assembly are arranged on the suspension support 3, the suspension assembly is used for suspending the top end of the cryostat 4, and the hoisting assembly is used for being connected with the hoisting equipment.

[0034] The suspension support 3 is detachably arranged on the upper end of the main support 2, the suspension support 3 is detached from the main support 2, and the connection of the suspension support 3 and the cryostat 4 is facilitated. After the cryostat 4 is connected with the suspension assembly, the hoisting equipment and the hoisting assembly are used for hoisting the suspension support 3 and the cryostat 4, so that the cryostat 4 enters the containing space of the main support 2 from the opening at the upper end of the main support 2, and the suspension support 3 is connected with the upper end of the main support 2. At this time, the cryostat 4 is suspended in the interior of the main support 2.

[0035] The tensioning mechanism is arranged on the main support 2, and after the cryostat 4 is suspended in the interior of the main support 2, the tensioning mechanism is connected with the bottom end of the cryostat 4. Through the pulling action of the tensioning mechanism on the bottom end of the cryostat 4, the movement of the bottom end of the cryostat 4 relative to the main support 2 can be limited, so that the cryostat 4 remains stable under the action of the suspension assembly and the tensioning mechanism.

[0036] The damping mechanism is arranged between the bottom bracket 1 and the main support 2, and is used for attenuating or isolating the vibration load between the bottom bracket 1 and the main support 2. When the transfer device for the cryostat provided in the embodiment of the present application is placed on a transport vehicle for transportation, various vibrations and dynamic loads received by the transport vehicle and the bottom bracket 1 can be greatly attenuated, so that the influence of the vibrations and the dynamic loads on the main support 2 is reduced or even avoided. Moreover, the cryostat 4 is suspended in the interior of the main support 2, and the cryostat 4 is in a suspended state, so that the transmission of the vibrations and the dynamic loads from the main support 2 to the cryostat 4 can be attenuated.

[0037] In this way, the vibrations and the dynamic loads received by the cryostat 4 are greatly reduced, especially when the cryostat 4 is transferred over a long distance and in multiple road conditions, the risk of damage to the cryostat 4 is greatly reduced, and the problem that the cryostat 4 is easily damaged during the transfer of the cryostat 4 in the related art is solved.

[0038] In the embodiment of the present application, the damping mechanism is arranged in the form of a steel wire rope damper.

[0039] Specifically, the damping mechanism comprises a plurality of steel wire rope dampers, and the steel wire rope dampers are distributed along the circumference of the bottom bracket 1 at intervals. The steel wire rope dampers have damping parts, and the axes of the damping parts of at least two steel wire rope dampers are arranged at an angle.

[0040] Each steel wire damper can attenuate and isolate the transmission of vibration in three-dimensional directions. By setting the axes of the damping parts of at least two steel wire dampers at an angle, the attenuation and isolation of vibration can be more sufficient, and the damping effect of the damping mechanism can be improved.

[0041] The steel wire dampers spaced along the transverse direction of the bottom bracket 1 are first steel wire dampers 5, and the axes of the damping parts of the first steel wire dampers 5 are parallel to the transverse direction of the bottom bracket 1. The first steel wire dampers 5 are provided in two groups, and each group of the first steel wire dampers 5 is spaced along the transverse direction of the bottom bracket 1.

[0042] The steel wire dampers spaced along the longitudinal direction of the bottom bracket 1 are second steel wire dampers 6, and the axes of the damping parts of the second steel wire dampers 6 are parallel to the longitudinal direction of the bottom bracket 1. The second steel wire dampers 6 are provided in two groups, and each group of the second steel wire dampers 6 is spaced along the longitudinal direction of the bottom bracket 1.

[0043] In specific embodiments, each group of the first steel wire dampers 5 includes ten steel wire dampers, each group of the second steel wire dampers 6 includes three steel wire dampers, and the damping mechanism includes a total of 26 steel wire dampers, forming a multi-point and multi-dimensional flexible suspension and damping system that can effectively absorb and dissipate the wideband vibration transmitted from the load-carrying part of the transport vehicle and the impact energy caused by the uneven road surface, significantly reduce the acceleration peak transmitted to the cryostat 4, and maximize the protection of the internal precision components of the cryostat 4 from damage.

[0044] The steel wire damper includes a first connecting plate, a second connecting plate, and a damping steel wire 21. The first connecting plate is used to connect the bottom bracket 1, and the second connecting plate is used to connect the main body support 2. The damping steel wire 21 is arranged between the first connecting plate and the second connecting plate, and the first connecting plate and the second connecting plate are connected by the damping steel wire 21. The damping steel wire 21 serves as the damping part of the steel wire damper, and the damping steel wire 21 is in a spiral shape, with the central axis of the damping steel wire 21 being the axis of the damping part. The damping steel wire 21 is formed by weaving high-strength steel wires, and has a nonlinear stiffness characteristic.

[0045] Specifically, a second mounting plate 22 can be provided on the bottom bracket 1, and the second mounting plate 22 is fixedly connected to the bottom bracket 1 by bolts. A third mounting plate 23 is provided at the bottom end of the main body support 2, and the third mounting plate 23 is fixedly connected to the main body support 2 by bolts. One of the first connecting plate and the second connecting plate of the steel wire damper is fixed to the second mounting plate 22, and the other is fixed to the third mounting plate 23. The second mounting plate 22 and the third mounting plate 23 are arranged at an angle relative to the planes in which the transverse direction and the longitudinal direction of the bottom bracket 1 lie.

[0046] In this embodiment of the invention, the suspension assembly includes a support shaft 7, a sheave 8, and a suspension wire rope 9.

[0047] The support shaft 7 is set on the suspension bracket 3. When the suspension bracket 3 is installed on the main support 2, the axis of the support shaft 7 is set along the longitudinal direction of the bottom bracket 1.

[0048] The support shaft 7 is rotatably connected to the suspension bracket 3. The axis of rotation of the support shaft 7 relative to the suspension bracket 3 coincides with the axis of the support shaft 7. That is, the support shaft 7 is rotatably mounted on the suspension bracket 3 around its own axis. A pair of support shafts 7 are provided, and the axes of the pair of support shafts 7 coincide. The pair of support shafts 7 are distributed longitudinally at intervals along the bottom bracket 1.

[0049] A sheave 8 is mounted on a support shaft 7, and each support shaft 7 is equipped with a sheave 8, the axis of which coincides with the axis of the support shaft 7. The sheave 8 has rope grooves, with two rope grooves corresponding to each support shaft 7, and each rope groove corresponding to one suspension wire rope 9. That is, each support shaft 7 corresponds to two suspension wire ropes 9.

[0050] One end of the suspension wire rope 9 is looped around the rope groove of the rope pulley 8, and the other end of the suspension wire rope 9 is used to connect to the cryogenic thermostat 4. One of the suspension wire ropes 9 on each support shaft 7 extends to one end of the cryogenic thermostat 4 laterally, and the other suspension wire rope 9 extends to the other end of the cryogenic thermostat 4 laterally.

[0051] like Figure 4 As shown, there are four suspension connection points between the suspension assembly and the top of the cryogenic thermostat 4, which can improve the suspension stability of the cryogenic thermostat 4.

[0052] The end of the suspension wire rope 9 is looped in the rope groove of the rope sheave 8, which not only ensures the stability of the suspension wire rope 9 and prevents it from slipping off the rope sheave 8, but also allows the suspension wire rope 9 to rotate relative to the rope sheave 8. In addition, the support shaft 7 on which the rope sheave 8 is located can rotate relative to the suspension bracket 3, which facilitates the angle adjustment of the suspension wire rope 9.

[0053] In this embodiment of the invention, the tensioning mechanism includes multiple fall arresters 10, which are housed within the accommodating space of the main support 2. Along the transverse direction of the bottom bracket 1, the multiple fall arresters 10 are symmetrically distributed at both ends of the main support 2. The main body of each fall arrester 10 is mounted on the main support 2, and the traction rope of each fall arrester 10 is used to connect to the bottom end of the cryogenic thermostat 4 to generate a pulling force on the bottom end of the cryogenic thermostat 4.

[0054] When the cryostat 4 is suspended in the accommodating space of the main support 2, the plurality of arresters 10 are symmetrically distributed at both ends of the main support 2. The arresters 10 generate pulling forces in different directions on the bottom end of the cryostat 4, and the pulling forces generated by the arresters 10 on the bottom end of the cryostat 4 can be combined to limit the movement of the bottom end of the cryostat 4 relative to the main support 2, thereby limiting the swing of the cryostat 4 relative to the main support 2 when the transport vehicle starts, brakes, and the like, and ensures the stability of the cryostat 4 and avoids collision impact on the cryostat 4.

[0055] In the embodiment, the main support 2 includes a first longitudinal support 13, a second longitudinal support 14, a third longitudinal support 15, and a pair of main supports.

[0056] The main support is trapezoidal, and the main support has a top beam 11, a bottom beam 12, a diagonal beam 24, and a middle support beam 25. As shown in Figure 6 The length of the top beam 11 is smaller than the length of the bottom beam 12. The diagonal beam 24 is arranged between the top beam 11 and the bottom beam 12, one end of the diagonal beam 24 is fixedly connected with the end of the top beam 11, and the other end of the diagonal beam 24 is fixedly connected with the end of the bottom beam 12. The middle support beam 25 is arranged between the top beam 11 and the bottom beam 12, one end of the middle support beam 25 is fixedly connected with the top beam 11, and the other end of the middle support beam 25 is fixedly connected with the bottom beam 12.

[0057] The pair of main supports are spaced apart along the longitudinal direction of the bottom bracket 1, the bottom beam 12 is used to connect the damping mechanism, and the top beam 11 is used to connect the suspension support 3.

[0059] The bottom beam 12 of the pair of main supports and the first longitudinal support 13 form a rectangle, which is used as the bottom frame of the main support 2, and is used to be connected with the bottom bracket 1 through the damping mechanism. The top beam 11 of the pair of main supports is connected by two second longitudinal supports 14 corresponding to the ends of the top beam 11. The main support 2 is a rigid frame structure, which is used as the core load-bearing framework of the transfer device for the cryostat.

[0060] Among the top beam 11, the bottom beam 12, the diagonal beam 24, the middle support beam 25, the first longitudinal support 13, and the second longitudinal support 14, two adjacent ones can be fixed by welding.

[0064] In the embodiment, both ends of the at least one second longitudinal support 14 are detachably connected to the top cross beam 11. After one of the second longitudinal supports 14 is detached from the main support, the space between the inclined beams 24 of the pair of main supports is connected to the space between the top cross beams 11 of the pair of main supports, and the low-temperature thermostat 4 can enter and exit the accommodation space of the main support 2 along the transverse direction of the bottom bracket 1, which is more convenient for the installation of the low-temperature thermostat 4 in the main support 2. After the low-temperature thermostat 4 is installed in the main support 2, the second longitudinal support 14 is installed to the top cross beam 11 of the main support 2.

Each first lifting ring 18 can be connected with the lifting rope of the hoisting device, so as to hoist the suspension support 3 by using the hoisting device.

[0074] The first lifting ring 18 is threadedly connected with the suspension support 3, and the axis of the thread is arranged in the vertical direction of the bottom bracket 1.

[0075] Specifically, the first lifting ring 18 includes a first lifting ring portion and a first shaft portion. The first lifting ring portion is annular in structure and is used to be connected with the lifting rope of the hoisting device. One end of the first shaft portion is fixedly connected with the first lifting ring portion, and the first shaft portion is provided with an external thread. The suspension support 3 is provided with a threaded hole, and when the suspension support 3 is located on the main support 2, the axis of the threaded hole is arranged in the vertical direction of the bottom bracket 1.

[0076] When the first lifting ring 18 is connected with the suspension support 3, the axis of the first shaft part of the first lifting ring 18 is arranged along the vertical direction of the bottom bracket 1. The first shaft part is threadedly connected with the suspension support 3, and by screwing the first shaft part, the distance between the first lifting ring part and the suspension support 3 can be adjusted along the vertical direction of the bottom bracket 1.

[0077] In the embodiment, a plurality of second lifting rings 19 are arranged at the upper end of the main support 2, and the plurality of second lifting rings 19 are arranged at intervals along the circumferential direction of the main support 2.

A threaded hole is arranged on the top beam 11 of the main support 2, and the axis of the threaded hole is arranged along the vertical direction of the bottom bracket 1.

[0080] When the second lifting ring 19 is connected with the main support 2, the axis of the second shaft part of the second lifting ring 19 is arranged along the vertical direction of the bottom bracket 1.

[0081] In combination with the threaded connection of the first lifting ring 18 with the suspension support 3 and the threaded connection of the second lifting ring 19 with the main support 2, the suspended cryostat 4 can be accurately leveled, so as to ensure that the center of gravity of the cryostat 4 is aligned with the geometric center of the suspension mechanism, or the center of gravity of the cryostat 4 is aligned with the geometric center of the transfer device for the cryostat as a whole. When the cryostat 4 is lifted into the main support 2 or the transfer device for the cryostat and the cryostat 4 as a whole are lifted into the transport vehicle, the unbalanced load can be avoided.

[0082] The hoisting ropes can be high-strength and low-elongation steel wire ropes or synthetic fiber ropes with equivalent performance. Each hoisting rope can be provided with a fall arrestor in parallel. The fall arrestor includes an elastic damping element and a mechanical self-locking assembly. The elastic damping element provides flexible damping force to quickly attenuate the swing energy when the normal transportation is started, braked or slightly swung. The mechanical self-locking assembly can be triggered instantaneously and rigidly lock the hoisting rope or provide extremely strong braking force when the tension of the hoisting rope is abnormally increased or the displacement is out of limit, thereby preventing the cryostat from colliding with other structures due to violent swinging and being the last important guarantee for preventing the equipment from overturning or the structure from being damaged.

[0083] In the embodiment, the design of the suspension mechanism needs to ensure that the cryostat 4 is always in a stable and controllable slight swing state during transportation and has sufficient safety margin to cope with emergency braking or accidental bumps.

[0088] The suspension mechanism and the cryostat 4 are hoisted to the inside of the main bracket 2 by using the hoisting equipment, and the end of the suspension bracket 3 of the suspension mechanism is lapped on the top beam 11 of the main bracket 2, and the suspension bracket 3 and the top beam 11 of the main bracket 2 are fixedly connected by using bolts. Then the detached second longitudinal bracket 14 is installed and reset.

[0089] The traction rope of the fall arrestor 10 on the third longitudinal bracket 15 is connected to the bottom end of the cryostat 4, so that the fall arrestor 10 has a tensioning force on the cryostat 4.

[0090] Finally, the hoisting ropes of the hoisting equipment are connected to the second lifting eye 19 on the main bracket 2, and the hoisting equipment simultaneously hoists the main bracket 2 and the suspension bracket 3 to hoist the transfer device for cryostats provided in the embodiment and the cryostat 4 suspended thereby to the carrying part of the transport vehicle. The bottom bracket 1 of the transfer device for cryostats is fixedly connected to the carrying part of the transport vehicle.

[0091] After that, the transport vehicle can be used for transportation.

[0092] In summary, the transfer device for the cryostat provided by the embodiment of the present application adopts 26 steel wire shock absorbers to form a multi-point and multi-dimensional flexible suspension and damping system, which protects the precise components inside the cryostat 4 from damage to the greatest extent; the suspension mechanism and the tensioning mechanism effectively suppress the low-frequency swing of the transport vehicle when accelerating, decelerating or turning, and solve the risk of equipment collision damage or vacuum seal failure caused by swing during transfer; the rigid connection of the main support 2 and the suspension support 3, combined with multi-point damping and anti-falling protection, provides flexibility while ensuring the structural integrity and equipment safety of the entire system under dynamic load.
