Description

Technical Field

[0001] The present invention relates to the technical field of superconducting magnet assembly, and in particular to a superconducting magnet core barrel outer component assembly tool and a core barrel outer component assembly method. Background Art

[0002] A superconducting magnet is an electromagnet made of a coil made of a type II superconductor with a high transition temperature and an exceptionally high critical magnetic field at a specific temperature. It has broad application prospects in fields such as magnetic resonance imaging, power transmission, and confined plasma for nuclear fusion reactions. A common type of superconducting magnet is a cylindrical superconducting magnet. It has a core tube inside, surrounded by an exoskeleton. The exoskeleton is equipped with a variety of external components, such as superconducting coils, temperature control modules, various circuit boards, and sensors. Among these, the assembly of superconducting coils is the most difficult of all external components. The weight of a superconducting coil generally exceeds 100 kilograms. As the magnetic field strength and field range increase, the weight of the superconducting coil will further increase, making it very difficult to accurately position the holes during assembly. In addition, the superconducting coil is wound very precisely. If it is deformed by force during assembly, the magnetic field strength may fluctuate due to the deformation of the coil, and the coil material may even delaminate and debond under the strong electromagnetic force.

[0003] The current assembly process for superconducting magnets is as follows: a base with a radius smaller than the superconducting coil is prepared. The superconducting coil to be installed at the bottom of the core barrel is placed on the base with a crane and lowered below the base. The core barrel is then centered on the base. The crane is then used to lift the bottom coil and assemble it onto the core barrel's outer frame. The superconducting coil to be installed at the top of the core barrel is then suspended and transported to the outer edge of the top of the core barrel using a crane and then assembled onto the core barrel's outer frame. Other external components are then assembled. However, this assembly process has the following drawbacks: the superconducting coil is suspended during assembly, making it prone to collisions. Furthermore, the crane is difficult to control the accuracy of both horizontal and vertical hole alignment, making assembly difficult and inefficient. Due to the difficulty in hole alignment, forcibly inserting bolts can easily damage the insulation layer of the superconducting coil. Summary of the Invention

DETAILED DESCRIPTION

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0050] Thus, a feature indicated in this specification is intended to illustrate one of the features of one embodiment of the present invention, rather than to imply that every embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other, not explicitly described, combinations. Thus, unless otherwise noted, the described combinations are not intended to be limiting.

[0051] The principle of the present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0052] The present invention proposes a superconducting magnet core barrel external parts assembly tool, comprising a base 1, a lifting platform 2, four support arms 3 and four suspended quick clamps 4; an outer skeleton 200 for fixing the external parts is pre-installed on the circumference of the core barrel 100; the lifting platform 2 is arranged in the middle of the base 1, and the core barrel 100 is centered on the lifting platform 2 through a diameter-changing centering mechanism arranged on the lifting platform 2; the four support arms 3 are fixed to the base 1 and are evenly distributed in a ring shape around the outer periphery of the lifting platform 2 with the central axis of the lifting platform 2 as the center, each support arm 3 is provided with a first U-shaped slot 31, and the bottom coil 300 to be assembled is slidably mounted in each first U-shaped slot 31; the four suspended quick clamps 4 are clamped and fixed to the outer skeleton 200, each suspended quick clamp 4 is provided with a second U-shaped slot 41, and the top coil 400 to be assembled is slidably mounted in each second U-shaped slot 41. Among them, the number of support arms 3 and suspended quick clamps 4 can be increased according to the weight of the coil.

[0053] The assembly of the exoskeleton 200 and the core barrel 100 is completed in the early process. This embodiment is used to assemble superconducting coils and external parts such as circuit boards, sensors, and temperature control components to the exoskeleton 200. After assembly, the overall mass is about 1200KG, the core barrel 100 and the exoskeleton 200 mass is about 800KG, and a single superconducting coil is about 150KG. There are two superconducting coils, one of which is located on the outer periphery of the top of the core barrel 100, namely the top coil 400; the other superconducting coil is located on the outer periphery of the bottom of the core barrel 100, namely the bottom coil 300. The assembly tooling of the external parts of the superconducting magnet core barrel 100 uses the support arm 3 and the suspended quick clamp 4 to respectively lift the superconducting coils at the bottom and top, and can achieve rapid hole positioning by circumferentially rotating the superconducting coils, which reduces the difficulty of hole alignment and thus improves assembly efficiency, and avoids collisions during the suspended assembly of the superconducting coils.

[0054] In addition, the purpose of centering the core barrel 100 is to make the bottom coil 300 coincide with the axis of the core barrel 100 to avoid radial adjustment of the heavy core barrel 100 or the bottom coil 300 at a later time.

[0055] In this embodiment, the variable diameter centering mechanism consists of four centering modules 5 evenly arranged in a ring shape on the top of the lifting platform 2, centered around the central axis of the lifting platform. A ramp chute 51 is provided on the side of the centering module 5 facing the center of the lifting platform 2. A variable diameter slider 53 with an L-shaped support plate 52 is slidably installed in the ramp chute 51. The bottom of the L-shaped support plate 52 is connected to the lifting platform 2 via a lifting spring 54. In the unloaded state, the L-shaped support plate 52 rises to the top of the ramp chute 51 under the action of the lifting spring 54. When the core barrel 100 is loaded, the core barrel 100 contacts and presses all the L-shaped support plates 52 to descend synchronously until they land on the top surface of the lifting platform 2. During the oblique descent process, all the L-shaped support plates 52 gradually approach the center of the lifting platform 2 and squeeze the core barrel 100 to achieve centering.

[0056] In this embodiment, the bottom of the first U-shaped slot 31 is elastically provided with a first roller 32 for mounting the bottom coil 300. The axis of rotation of each first roller 32 converges on the central axis of the core tube 100. The first roller 32 is used to rotate the bottom coil 300 circumferentially for assembly and positioning.

[0057] The support arm 3 also includes a shell 33, a first bracket 34, a pressure handle 35 and a buffer spring 36. The first U-shaped slot 31 is located at the top of the shell 33; the first bracket 34 is vertically slidably arranged in the shell 33, the buffer spring 36 is arranged at the bottom of the first bracket 34, and the first roller 32 is rotatably installed on the top of the first bracket 34; the pressure handle 35 is used to lift the first bracket 34, the force-applying section of the pressure handle 35 is rotatably arranged in the shell 33, and the gripping section of the pressure handle 35 extends out of the shell 33.

[0058] Support arm 3 not only supports the bottom coil 300 during assembly but also aligns the assembly holes between the bottom coil 300 and the exoskeleton 200. During assembly, the height of core barrel 100 is adjusted using lifting platform 2 until the assembly hole for the bottom coil 300 on the exoskeleton 200 is no lower than the assembly hole of the bottom coil 300. Assemblers manually rotate the bottom coil 300 to align the holes horizontally. If there is still any longitudinal deviation in the assembly hole positioning, the bottom coil 300 can be slightly tilted using the pressure handle 35 to facilitate smooth insertion of the bolts into the assembly holes.

[0059] In this embodiment, a second roller 42 for mounting the top coil 400 is elastically provided at the bottom of the second U-shaped slot 41. The axis of rotation of each second roller 42 converges on the central axis of the core tube 100. The second roller 42 is used to rotate the top coil 400 circumferentially for assembly and positioning.

[0060] The suspended quick clamp 4 also includes a box body 43, a side pull rod 44, a pressure rod 45 and a clamp 46, and the second U-shaped slot 41 is located at the top of the box body 43; the box body 43 is provided with a through hole 47 in the left and right directions, the side pull rod 44 is inserted into the through hole 47, the pressure rod 45 is hinged to one end of the side pull rod 44 outside the box body 43, and the rotating end of the pressure rod 45 is provided with a cam structure 451 for pushing and pulling the side pull rod 44; the outer skeleton 200 is provided with a linear rib 210 extending axially along the core tube 100, and the linear rib 210 is provided with a mounting groove 220, and the other end of the side pull rod 44 passes through the through hole 47 and continues to pass through the mounting groove 220 to be rotatably connected with the clamp 46.

[0061] The suspended quick clamp 4 utilizes the structure of the exoskeleton 200 to support and align the top coil 400. The exoskeleton 200 is equipped with eight linear ribs 210, which extend axially along the core barrel and are evenly distributed in a circular pattern centered on the core barrel's central axis. When the suspended quick clamp 4 is secured to the linear ribs 210, they also form a circular pattern, automatically aligning the top coil 400 mounted on the suspended quick clamp 4 with the core barrel 100.

[0062] The disassembly and installation of the suspended quick clamp 4 is also very convenient. The clamp 46 can be rotated. After the clamp 46 passes through the installation slot 220, it is rotated 90° to clamp it on one side of the linear rib 210, and then the pressure rod 45 on the other side of the linear rib 210 is pressed down, so that the suspended quick clamp 4 is clamped and fixed on the linear rib 210.

[0063] The quick-release clamp 4 also includes a second bracket 48, which slides vertically within the housing 43. A calibration spring 49 is attached to the bottom of the second bracket 48. The top of the housing 43 has an opening, through which the top of the second bracket 48 extends out of the housing 43. A second roller 42 is rotatably mounted on the top of the second bracket 48. The compression of the calibration spring 49 has been calculated to ensure that, when the four quick-release clamps 4 collectively support the top coil 400, the height of the mounting hole for the top coil 400 is no lower than the height of the corresponding mounting hole on the exoskeleton 200. If there is longitudinal deviation in the mounting hole positioning, the top coil 400 can be pressed downward to align the mounting hole, allowing for smooth bolt installation.

[0064] In this embodiment, a turntable 6 is also provided on top of the lifting platform 2 to support the core barrel 100 for circumferential rotation. After completing the assembly of the bottom coil 300 and the top coil 400, assemblers can rotate the core barrel 100 using the turntable 6 on one side of the superconducting magnet core barrel 100 exterior component assembly tool to assemble other exterior components around the core barrel 100, without having to change their own position, thereby improving assembly efficiency.

[0065] The turntable 6 includes a disk surface 61, a slewing bearing 62, a drive motor 63 and a transmission gear 64;

[0066] The inner ring of the slewing bearing 62 is fixed to the top of the platform 2, while the outer ring is fixed to the bottom of the disk 61. A number of alignment modules (five groups) are fixed to the top of the disk 61. A drive motor 63 is fixed to the bottom of the platform 2. The rotating shaft of the drive motor 63 passes through the platform 2 and is connected to the outer ring of the slewing bearing 62 via a transmission gear 64. When powered, the drive motor 63 drives the outer ring of the slewing bearing 62 to rotate, thereby driving the core barrel 100 to rotate synchronously.

[0067] The present invention also provides a method for assembling a core barrel outer component. The outer component is assembled on the outer frame 200 of the core barrel 100 using the superconducting magnet core barrel 100 outer component assembly tool described in any of the above embodiments. The outer component includes a bottom coil 300 and a top coil 400. The assembly steps are as follows:

[0068] A. Install the bottom coil 300 in each first U-shaped slot 31;

[0069] B. Use a crane to load the core barrel 100 onto the lifting platform 2. When the core barrel 100 is lowered to the lifting platform 2, the core barrel 100 is automatically centered and calibrated by the diameter-changing centering mechanism;

[0070] C. Position the bottom coil 300 and the outer frame 200 by manually adjusting the bottom coil 300 in the circumferential direction and adjusting the height of the core barrel 100 using the lifting platform 2. After positioning, assemble the bottom coil 300 to the outer frame 200 with bolts;

[0071] D. Install the suspended quick clamp 4 on the outer frame 200 and set the top coil 400 in each second U-shaped slot 41;

[0072] E. Circumferentially adjust the top coil 400 to position the mounting holes of the top coil 400 and the exoskeleton 200. After positioning, assemble the top coil 400 to the exoskeleton 200 with bolts.

[0073] F. Assemble other exterior parts.

[0074] It can be foreseen from the above method that the superconducting magnet core barrel 100 external parts assembly tool of the present invention respectively lifts the bottom and top superconducting coils through the support arm 3 and the suspended quick clamp 4, and can achieve rapid hole positioning by circumferentially rotating the superconducting coils, and avoids collisions during the suspended assembly of the superconducting coils; the core barrel 100, the bottom coil 300 and the top coil 400 do not need to be manually adjusted and aligned during assembly, and do not need to adjust the position radially.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
