[0047] The core of this invention is to provide a high-temperature superconducting magnet cold head installation device to improve the installation efficiency of the high-temperature superconducting magnet cold head, while preventing bumps and knocks during the installation process and extending the service life of the high-temperature superconducting magnet cold head.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that, for ease of understanding of this solution, the portion of the high-temperature superconducting magnet cold head 100 used for installation inside the magnet vacuum chamber 800 is defined as the first cold head 101, and the portion located outside the magnet vacuum chamber 800 is defined as the second cold head 102. The high-temperature superconducting magnet cold head 100 is a commonly used refrigeration device for cooling high-temperature superconducting magnets in the prior art. Its cooling principle and specific structure will not be elaborated here. The focus of this application is not to improve the structure of the high-temperature superconducting magnet cold head 100.

[0050] like Figure 5 As shown in the figure, an embodiment of the present invention discloses a high-temperature superconducting magnet cold head installation device for assisting in the installation of a high-temperature superconducting magnet cold head 100, including an upper pressure plate 200, a lower pressure plate 300, and a hoisting part 400.

[0051] The upper pressure plate 200 and the lower pressure plate 300 are fixedly connected by a fixing assembly, so that the upper pressure plate 200 and the lower pressure plate 300 form a clamping space for clamping the second cold head 102. Those skilled in the art will understand that there are various solutions for the fixing assembly, including bolt and nut fixing or other fixing methods. The specific fixing assembly configuration is selected according to the actual situation, as long as it can effectively fix the second cold head 102 and facilitate disassembly after hoisting.

[0052] The lifting part 400 is disposed on the upper pressure plate 200, and the lifting part 400 has a lifting hole 401 for cooperating with lifting equipment. Those skilled in the art will understand that the lifting part 400 and the upper pressure plate 200 can be integrally processed or separately processed, and fixedly connected by means of fixed connection, such as welding connection or fastener connection.

[0053] The high-temperature superconducting magnet cold head installation device provided by this invention has an upper pressure plate 200 and a lower pressure plate 300 fixedly connected by a fixing assembly to clamp the second cold head 102. A hoisting device cooperates with a hoisting part 400 to hoist the high-temperature superconducting magnet cold head 100 to the required installation position, allowing the first cold head 101 to be installed inside the magnet vacuum chamber 800. The high-temperature superconducting magnet cold head installation device provided by this invention improves the installation efficiency of the high-temperature superconducting magnet cold head 100 and prevents damage from impacts during installation, thus extending the service life of the high-temperature superconducting magnet cold head 100. Furthermore, the high-temperature superconducting magnet cold head installation device provided by this invention has a simple structure, is easy to manufacture, and is easy to install and disassemble.

[0054] To ensure that the high-temperature superconducting magnet cold head 100 remains horizontal during hoisting, such as Figure 3As shown, in a specific embodiment of the present invention, the high-temperature superconducting magnet cold head mounting device further includes a balancing component 500 disposed on the hoisting part 400. Because the first cold head 101 extends a relatively long length beyond the high-temperature superconducting magnet cold head mounting device, the center of gravity of the high-temperature superconducting magnet cold head 100 is biased towards one side of the first cold head 101. In order to prevent deflection during hoisting, the balancing component 500 is disposed on the side of the hoisting part 400 opposite to the first cold head 101.

[0055] The balancing assembly 500 is used to keep the second cold head 102 relatively horizontal, preventing the second cold head 102 from rotating during the hoisting process, thereby ensuring that the high-temperature superconducting magnet cold head 100 remains horizontal during hoisting. Those skilled in the art will understand that the balancing assembly 500 can be arranged in various ways. It can be used by adding a counterweight to one side of the second cold head 102 to maintain the balance of the lifting point and keep the high-temperature superconducting magnet cold head 100 horizontal. Alternatively, it can be used by setting a support rod against the second cold head 102 to prevent rotation. The specific arrangement can be selected according to the actual situation and is not limited here.

[0056] like Figure 4 As shown, based on the above embodiment, the balancing assembly 500 includes a balance bar 501 and a support device 502. One end of the balance bar 501 is fixed to the lifting part 400, and the other end extends away from the lifting part 400. Those skilled in the art will understand that the balance bar 501 and the lifting part 400 can be connected by a plug-in connection for easy assembly and disassembly, or by a welding connection for fixed connection. The specific connection method is not limited here; those skilled in the art can determine the appropriate connection method according to the specific circumstances.

[0057] A support device 502 is mounted on the balance bar 501, and its pressing end is used to press against the second cold head 102 to keep the second cold head 102 in a horizontal position, preventing it from deflecting upwards. This ensures that the high-temperature superconducting magnet cold head 100 remains stable and as horizontal as possible. Those skilled in the art will understand that the support device 502 can be a support rod or a piston cylinder, as long as it effectively presses against the second cold head 102 to keep it horizontal. The minimum length of the balance bar 501 is set to meet the installation requirements of the support device 502.

[0058] like Figure 5As shown, based on the above embodiment, the support device 502 includes a support screw 5021 and a fastening nut 5022. The balance bar 501 has a mounting hole, the first end of the support screw 5021 passes through the mounting hole, and the second end is provided with a pressing block for pressing against the second cold head 102. The pressing block increases the contact area, reduces pressure, and prevents the second end of the support screw 5021 from damaging the second cold head 102.

[0059] The fastening nut 5022 is threadedly engaged with the support screw 5021. There are two fastening nuts 5022, which are respectively pressed on both sides of the balance bar 501. That is, fastening nuts 5022 are provided on both the upper and lower sides of the balance bar 501. Those skilled in the art will understand that there is at least one fastening nut 5022 on the upper and lower sides of the balance bar 501. When it is necessary to adjust the support screw 5021 to press against the second cold head 102, rotate the fastening nut 5022 to allow the support screw 5021 to be adjusted up and down. Adjust the support screw 5021 so that the pressing block is pressed against the second cold head 102, and the high-temperature superconducting magnet cold head 100 is kept in a horizontal position. Rotate the fastening nut 5022 so that the two fastening nuts 5022 are respectively pressed against both sides of the balance rod 501. In the figure, the fastening nut 5022 on the side closer to the second cold head 102 (the fastening nut 5022 located on the lower side of the balance rod 501) is not pressed against the balance rod 501, which is an intermediate adjustment process and has not yet been completed. When it is not necessary for the support screw 5021 to press against the second cold head 102, rotate the fastening nut 5022 away from the second cold head 102 to disengage the fastening nut 5022 away from the balance rod 501.

[0060] To ensure that the contact surface between the pressing block and the second cold head 102 remains tightly pressed and fitted during hoisting, such as Figure 5 As shown, in a specific embodiment of the present invention, the pressing block is hinged to the second end of the support screw 5021, that is, the pressing block can rotate relative to the second end of the support screw 5021. When the high-temperature superconducting magnet cold head 100 is hoisted, if the second cold head 102 deflects, the pressing block can deflect with the second cold head 102 and always maintain a pressed and fitted state with the second cold head 102.

[0061] In a specific embodiment of the present invention, the support device 502 is a piston cylinder fixed to the balance bar 501, and the piston rod of the piston cylinder is used to press against the second cold head 102. The piston cylinder can be fixed to the balance bar 501 by means of flanges, bolts or other fasteners, and the piston rod extends out to press against the second cold head 102 to prevent the second cold head 102 from deflecting, thereby ensuring that the second cold head 102 remains in a horizontal state.

[0062] To maintain relative weight balance on both sides of the lifting point of the hoisting equipment, such as Figure 3 As shown, the high-temperature superconducting magnet cold head mounting device disclosed in this invention also includes an extension rod 600 slidably sleeved on the balance rod 501. The extension rod 600 is slidably configured, allowing for adjustment of its length extending beyond the balance rod 501. This makes it easier to adjust the weight on both sides of the lifting point to maintain relative balance, thereby ensuring the second cold head 102 remains horizontal. Those skilled in the art will understand that the weight on both sides of the lifting point can also be adjusted to maintain relative balance by adding a counterweight to the balance rod 501 on one side of the second cold head 102; the specific method can be selected according to the actual situation.

[0063] To facilitate the installation and disassembly of the balance bar 501 and the lifting unit 400, such as Figure 5 and Figure 6 As shown, in a specific embodiment of the present invention, the hoisting part 400 is provided with a balance bar mounting groove 402. One end of the balance bar 501 is inserted into the balance bar mounting groove 402 and locked by a locking assembly. Specifically, the locking assembly can be a locking bolt and a locking nut. The balance bar mounting groove 402 has a first through hole, and the balance bar 501 has a corresponding second through hole. The locking bolt passes through the first through hole and the second through hole, and the balance bar 501 is locked by the locking nut. Those skilled in the art can select specific locking assemblies according to actual conditions.

[0064] It should be noted that the high-temperature superconducting magnet is a mirror structure (i.e., the high-temperature superconducting magnet may be located on the first side or the second side of the magnet vacuum chamber 800), and the installation of the high-temperature superconducting magnet cold head 100 is also a mirror structure (i.e., the high-temperature superconducting magnet cold head 100 needs to be installed on the first side or the second side of the magnet vacuum chamber 800). In order to enable the high-temperature superconducting magnet cold head installation device to simultaneously meet the installation requirements of both types of high-temperature superconducting magnet cold heads, the high-temperature superconducting magnet cold head installation device disclosed in this invention has at least one side of the upper pressure plate 200 and the lower pressure plate 300 locked by a locking rod 700. The upper pressure plate 200 and the lower pressure plate 300 are provided with adjustment holes for the locking rod 700 to pass through, so as to adjust the locking position of the locking rod 700.

[0065] It should be noted that regardless of whether the high-temperature superconducting magnet is located on the first or second side of the magnet vacuum chamber 800, the compressor of the second cold head 102 always extends outward from the magnet vacuum chamber 800. Taking the case where only one side of the upper pressure plate 200 and lower pressure plate 300 is locked by the locking rod 700 as an example, ... Figure 1 and Figure 2 As shown, when the high-temperature superconducting magnet is located on the first side of the magnet vacuum chamber 800, the first side is as follows: Figure 2As shown in the installation position, the locking rod 700 is located on the first side of the upper pressure plate 200 and the lower pressure plate 300. When the high-temperature superconducting magnet is located on the second side of the magnet vacuum chamber 800, in order to facilitate the disassembly and assembly of the high-temperature superconducting magnet cold head mounting device and to ensure accurate positioning of the first cold head 101 with the magnet inside the magnet vacuum chamber 800, the locking rod 700 is positioned on the second side of the upper pressure plate 200 and the lower pressure plate 300. Correspondingly, the adjustment holes provided on the upper pressure plate 200 and the lower pressure plate 300 for the locking rod 700 to pass through are located on the second side. Those skilled in the art will understand that the other side of the upper pressure plate 200 and the lower pressure plate 300 can be fixed by bolts and nuts, or by locking the locking rod 700.

[0066] like Figure 5 and Figure 7 As shown, based on the above embodiment, the adjustment hole is a strip-shaped hole. When the high-temperature superconducting magnet is located on the first side of the magnet vacuum chamber 800, the locking rod 700 engages with the first end of the strip-shaped hole. When the high-temperature superconducting magnet is located on the second side of the magnet vacuum chamber 800, the locking rod 700 engages with the second end of the strip-shaped hole. For ease of explanation, as... Figure 2 As shown, when the high-temperature superconducting magnet is located on the first side of the magnet vacuum chamber 800, the side of the upper pressure plate 200 closest to the magnet vacuum chamber 800 is defined as the first upper pressure plate surface, and the side furthest from the magnet vacuum chamber 800 is defined as the second upper pressure plate surface. It should be noted that a cooling adapter 900 is provided inside the magnet vacuum chamber 800. One end of the cooling adapter 900 is connected to the first cold head 101, and the other end is connected to the high-temperature superconducting magnet. When the high-temperature superconducting magnet is located on the first side of the magnet vacuum chamber 800, i.e.... Figure 2 When the position shown is such that the first upper pressure plate is close to the magnet vacuum chamber 800, the locking rod 700 engages with the first end of the slotted hole, allowing the first cold head 101 and the cooling adapter 900 to be accurately positioned, enabling rapid connection between the two. When the high-temperature superconducting magnet is located on the second side of the magnet vacuum chamber 800, the second upper pressure plate is close to the magnet vacuum chamber 800. To ensure accurate positioning of the first cold head 101 and the cooling adapter 900, and to maintain a fixed distance between the second upper pressure plate and the magnet vacuum chamber 800, the locking rod 700 engages with the second end of the slotted hole.

[0067] Of course, the adjustment hole can also be set as a first tie rod fixing hole and a second tie rod fixing hole. When the high-temperature superconducting magnet is located on the first side of the magnet vacuum chamber 800, the locking tie rod 700 engages with the first tie rod fixing hole, so that the first cold head 101 and the cooling adapter 900 are accurately positioned; when the high-temperature superconducting magnet is located on the second side of the magnet vacuum chamber 800, the locking tie rod 700 engages with the second tie rod fixing hole. Those skilled in the art will understand that the specific setting of the adjustment hole can be selected according to the actual situation.

[0068] To ensure the fixed connection between the balance bar 501 and the balance bar mounting slot 402 during mirror mounting of the high-temperature superconducting magnet, based on the above embodiment, as follows: Figure 5 and Figure 6 As shown, both sides of the hoisting part 400 have balance bar mounting slots 402. When the high-temperature superconducting magnet is located on the first side of the magnet vacuum box 800, the balance bar 501 is fixedly connected with the balance bar mounting slot 402 on one side of the hoisting part. When the high-temperature superconducting magnet is located on the second side of the magnet vacuum box 800, the balance bar 501 is fixedly connected with the balance bar mounting slot 402 on the other side of the hoisting part. This allows the high-temperature superconducting magnet installation device to meet the installation requirements of the high-temperature superconducting magnet in two positions.

[0069] To improve the stability of the connection between the balance bar 501 and the lifting unit 400, such as Figure 6 As shown in a specific embodiment of the present invention, the balance bar mounting slots 402 located on both sides of the hoisting part 400 are connected. When the balance bar 501 is inserted into the balance bar mounting slot 402, one end of the balance bar 501 inserted into the balance bar mounting slot 402 can extend into the connected balance bar mounting slot 402 on the other side. Both sides are locked by locking components, further ensuring the firmness of the connection between the balance bar 501 and the hoisting part 400. Of course, the balance bar 501 can also be inserted only into the balance bar mounting slot 402 on one side and locked by locking components.

[0070] To ensure that the balance bar 501 remains stationary during hoisting, so that the crimping end of the support device 502 is crimped against the second cold head, such as... Figure 5 As shown, in a specific embodiment of the present invention, a threaded hole is provided on the balance bar mounting groove 402 for installing a set screw. One end of the set screw passes through the threaded hole and abuts against the balance bar 501, effectively preventing the balance bar 501 from rotating during hoisting and keeping it fixed.

[0071] To further ensure that the balance bar 501 remains fixed during the hoisting process, based on the above embodiment, threaded holes are provided in the balance bar mounting slots 402 on both sides of the hoisting part 400, and the set screws correspond one-to-one with the threaded holes, which further ensures the stability of the balance bar 501.

[0072] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
