[0015] Adopt the technical scheme, and multiple sliding slots are spaced apart and set up in the outer periphery of sliding hole, and are set up one by one with multiple inner support pieces, and each sliding slot gradually moves away from sliding hole in the radial direction of sliding hole from one end to the other end along its length direction, and multiple connecting holes are located in the outer periphery of multiple sliding slots, one end of each inner support piece close to first surface is provided with extension piece, and extension piece extends to pass through corresponding sliding slot along the thickness direction of connecting plate, one end of each extension piece away from corresponding inner support piece is provided with sliding bearing, and each sliding bearing is slidably connected to second surface, sliding rod is slidably connected with connecting plate through sliding hole, each connecting rod group includes two connecting rods that are parallel to each other, and both ends of each connecting rod are threadedly connected with the outer wall of sliding rod through each first threaded connection piece and threadedly connected with corresponding inner support piece through second threaded connection piece.

[0016] According to another specific embodiment of the present invention, the assembly fixture for the magnetically pulled single-crystal superconducting coil disclosed in this embodiment of the present invention has an L-shaped support frame and includes a first frame and a second frame that are perpendicular to each other; one end of the first frame is fixedly connected to one end of the second frame; and a connecting plate is fixed on the outer side of the first frame along its thickness direction.

[0017] The process of switching the superconducting coil from a horizontally placed position on the support surface to a vertically suspended position using this assembly fixture, and then installing it onto the side of the coil frame, firstly requires aligning the first surface of the connecting plate parallel to and against one of the surfaces of the superconducting coil along its height direction, and fixing both in place. Then, the assembly fixture and the superconducting coil need to be rotated to bring the superconducting coil into a vertically suspended position. By adopting the above technical solution, and setting the support frame to an L-shape with the connecting plate fixed to the outer side of its first frame along its thickness direction, after the connecting plate and the superconducting coil are connected, the space required for rotating the assembly fixture and the superconducting coil is only the space needed to place the superconducting coil. The flipping operation can also be completed within this space, enabling operation in confined spaces and saving installation space. Furthermore, the support frame has a simple structure, reducing the manufacturing cost and time cost of the fixture.

[0019] Using the above technical solution, since the support frame is L-shaped, after the connecting plate is connected to the superconducting coil, once the superconducting coil and assembly fixture are flipped to a vertically suspended state, they cannot maintain balance. By setting a weight assembly on the outside of the second frame, the superconducting coil and assembly fixture can maintain balance in the vertically suspended state. Moreover, the weights are commercially available finished parts and do not need to be manufactured separately, reducing the manufacturing cost and time cost of the assembly fixture. Furthermore, by setting an adjustment assembly on the inside of the second frame, and the adjustment assembly can slide along the thickness direction of the first frame, the vertically suspended state of the superconducting coil and assembly fixture can be moderately adjusted so that one of the surfaces of the superconducting coil along its height direction (i.e., the surface opposite to the surface where the superconducting coil is connected to the connecting plate) is parallel to the side of the coil frame and can be completely fitted, so as to facilitate the quick fixation of the superconducting coil to the side of the coil frame.

The support plate is fixed to the outside of the second frame, and the support plate is provided with a plurality of columnar protrusions protruding outward from the second frame. The weight body is located inside the area formed by the plurality of columnar protrusions on the support plate.

[0021] By adopting the above technical solution, multiple columnar protrusions are set on the support plate on the outside of the second frame, which can restrict the movement of the weight body on the support plate and ensure the safety of the installation process.

[0024] According to another specific embodiment of the present invention, the assembly fixture for the magnetically pulled single-crystal superconducting coil disclosed in this embodiment of the present invention further includes a threaded shaft and two shaft clips; the threaded shaft is fixed on the counterweight plate and extends out of the counterweight plate at both ends, the dumbbell is sleeved on the threaded shaft, and the two shaft clips are respectively fixed at the two ends of the threaded shaft.

Two shaft clips are set at the two ends of the threaded shaft to prevent the dumbbell from falling off during the sliding process and to ensure the safety of the installation.

[0026] According to another specific embodiment of the present invention, the assembly fixture for the magnetically pulled single-crystal superconducting coil disclosed in this embodiment of the present invention further includes a reinforcing rod.

[0029] By adopting the above technical solution and setting up lifting lugs, the assembly tooling can be easily hoisted. Attached Figure Description

Detailed Implementation

[0051] The common method in existing technology for assembling magnetically pulled single-crystal superconducting coils onto the mounting surface of a coil holder involves directly passing a sling through the inner ring of the superconducting coil, suspending it vertically, and then installing it directly onto the side of the coil holder. Due to the obstruction of the sling, the mounting surface of the superconducting coil cannot be completely and directly attached to the side of the coil holder. The area that is in contact with the coil must be fixed gradually, and then the sling is removed and the bolts used for fixing are tightened. Therefore, there are problems such as insecure installation, the risk of the coil falling off, and the possibility that the sling may slide and damage the superconducting coil during the transfer of the coil.

[0052] To address the aforementioned technical problems, this invention provides an assembly fixture for a magnetically pulled single-crystal superconducting coil. This fixture is used to switch the superconducting coil from a horizontally placed position on a support surface to a vertically suspended position and to install it onto the side of a coil frame. The fixture includes a support frame, a connecting plate, and an inner support assembly. The support frame secures the connecting plate and the inner support assembly. The superconducting coil is detachably and securely connected to the connecting plate. Multiple inner support members of the inner support assembly abut against the inner wall of the superconducting coil, allowing the superconducting coil to be fixed to the inner support assembly. This allows for selection of the connection method corresponding to the installation requirements of the superconducting coil, ensuring the safety of the entire installation. Furthermore, by fixing the superconducting coil with the inner support assembly, there is no relative sliding between the inner support members and the inner wall of the superconducting coil. Similarly, by fixing the superconducting coil with the connecting plate, there is also no relative sliding between the connecting plate and the superconducting coil, thus preventing damage to the superconducting coil. In addition, when the superconducting coil is in a horizontal state and fixedly connected to the connecting plate, it can be rotated to make the superconducting coil in a vertically suspended state, further fixing the superconducting coil to the inner support assembly. When it is not fixed to the connecting plate, the superconducting coil can be directly fixed to the side of the coil frame with fasteners, which can ensure the safety of the entire rotation process, and the entire installation process is convenient and efficient.

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0054] The assembly fixture for the magnetically pulled single-crystal superconducting coil provided by this utility model is used to switch the superconducting coil (i.e., the magnetically pulled single-crystal superconducting coil) from a horizontally placed state on a support surface to a vertically suspended state, and to install it onto the side of the coil frame. It should be noted that the superconducting coil being in a horizontally placed state on the support surface means that one surface of the superconducting coil along its height direction (this surface is also the mounting surface with the coil frame) is in contact with the support surface, and the height direction of the superconducting coil is perpendicular to the support surface. The superconducting coil being in a vertically suspended state means that the superconducting coil is not in contact with the support surface and the height direction of the superconducting coil is parallel to the support surface. The support surface can be the ground or other surfaces parallel to the ground.

[0055] like Figure 1 As shown, the superconducting coil 10 and its height direction ( Figure 1 The cross-section perpendicular to direction A in the superconducting coil 10 is annular, and the sidewall of the superconducting coil 10 is provided with a circumferential (A-direction) section along the superconducting coil 10. Figure 1 Multiple coil mounting holes 11 are spaced apart along the B direction of the superconducting coil 10. It should be noted that the multiple coil mounting holes 11 penetrate the superconducting coil 10 along its height direction. The superconducting coil 10 and its height direction (… Figure 1The cross-section perpendicular to direction A in the diagram can be circular or other ring shapes. Before installation, the superconducting coil 10 is generally placed horizontally on the support surface, meaning the height direction of the superconducting coil 10 is perpendicular to the support surface. Specifically, the superconducting coil 10 is a magnetically pulled single-crystal superconducting coil.

[0056] like Figure 2 As shown, the side of the coil frame 20 is perpendicular to the support surface, and the side wall of the coil frame 20 has multiple coil frame fixing holes 21. It should be noted that the multiple coil frame fixing holes 21 correspond one-to-one with and are adapted to the multiple coil mounting holes 11. When the superconducting coil 10 is in a vertically suspended state, that is, the superconducting coil 10 is not in contact with the support surface and the height direction of the superconducting coil 10 is parallel to the support surface, the superconducting coil 10 can be detachably fixed to the side wall of the coil frame 20 (e.g., threaded connection) by the cooperation of multiple fasteners (e.g., bolts) with the multiple coil mounting holes 11 and the multiple coil frame fixing holes 21.

[0057] like Figure 3 As shown, the assembly fixture 30 includes a support frame 100, a connecting plate 200, and an inner support assembly 300. Figures 3-5 As shown, the connecting plate 200 is fixedly installed on the support frame 100 and has a thickness direction ( Figures 3-5 The first surface 210 and the second surface 220 are arranged opposite each other in the C direction. The connecting plate 200 has a plurality of connecting holes 230 spaced apart. Each connecting hole 230 extends from the first surface 210 to the second surface 220. The plurality of connecting holes 230 correspond one-to-one with and are adapted to the plurality of coil mounting holes 11.

[0058] The connecting plate 200 and the superconducting coil 10 can be detachably fixedly connected through multiple connecting holes 230, multiple coil mounting holes 11, and multiple first fasteners. Each first fastener passes through the corresponding connecting hole 230 and is threadedly connected to the corresponding coil mounting hole 11. The first surface 210 is set opposite to one of the surfaces of the superconducting coil 10 along its height direction (i.e. the surface facing away from the support surface).

[0059] It should be noted that the superconducting coil 10 typically has a notch on one of its surfaces along its height direction, serving as the inlet and outlet for the superconducting wire. To avoid affecting the entry and exit of the superconducting wire, the connecting plate 200 also has a plate notch corresponding to the notch of the superconducting coil 10.

[0060] like Figures 3-5 As shown, the inner support assembly 300 is fixedly installed on the connecting plate 200, including multiple inner support members 310 and a pushing member. The multiple inner support members 310 are located on the side of the first surface 210 of the connecting plate 200 away from the second surface 220. When the inner support assembly 300 is located in the inner space of the superconducting coil 10, the pushing member can push the multiple inner support members 310 to move in the radial direction of the superconducting coil 10, such as...Figure 6 As shown, multiple inner support members 310 can abut against the inner wall surface of the superconducting coil 10.

[0061] Specifically, the pushing component can be a linkage structure, a telescopic structure, or other structures, as long as it can push the multiple inner support members 310 to move in the radial direction of the superconducting coil 10. For example, if the pushing component is a linkage structure, it can include a first connecting rod and multiple second connecting rods disposed on the outer periphery of the first connecting rod. Each second connecting rod is rotatably connected to the corresponding inner support member 310 and the first connecting rod. The first connecting rod is slidably connected to the connecting plate 200, and the multiple inner support members 310 are slidably connected to the connecting plate 200. In this way, the first connecting rod slides relative to the connecting plate 200, driving the multiple second connecting rods to rotate, which in turn causes the multiple inner support members 310 to slide relative to the connecting plate 200 and move in the radial direction of the superconducting coil 10, so that the multiple inner support members 310 can abut against the inner wall surface of the superconducting coil 10. For example, if the pushing component is a telescopic structure, it may include a support rod and multiple telescopic rods disposed on the outer periphery of the support rod. The support rod is fixed to the connecting plate 200, and each telescopic rod is fixedly connected to the corresponding inner support member 310. It can extend and retract along the radial direction of the superconducting coil 10. In this way, by controlling the extension and retraction of each telescopic rod, multiple inner support members 310 can be driven to move along the radial direction of the superconducting coil 10, so that multiple inner support members 310 can abut against the inner wall surface of the superconducting coil 10.

[0062] It should be noted that the number of internal support members 310 is at least two, for example, it can be as follows: Figure 3 The four shown can also be set to other numbers, as long as the inner support 310 and the inner wall surface of the superconducting coil 10 can be stably abutted.

[0063] The specific assembly process of one assembly method for the superconducting coil 10 is as follows: When the superconducting coil 10 is placed horizontally on the support surface, firstly, the first surface 210 of the connecting plate 200 is oriented towards the superconducting coil 10 (e.g., ...). Figure 7 As shown, the superconducting coil 10 is in a state of being ready to be connected at this time. The connecting plate 200 is further made parallel to and attached to one of the surfaces of the superconducting coil 10 along its height direction (e.g., ...). Figure 7 The upper surface of the superconducting coil 10 is connected to the connecting plate 200, which is detachably fixed to the superconducting coil 10. In the radial direction of the superconducting coil 10, multiple inner support members 310 have gaps with the inner wall surface of the superconducting coil 10. At this time, the superconducting coil 10 is in the first connected state. Then, the assembly fixture 30 and the superconducting coil 10 are rotated to bring the superconducting coil 10 into a vertically suspended state (e.g., ...). Figure 8 (As shown). Then, by pushing the pusher, multiple inner support members 310 are moved radially along the superconducting coil 10, causing the multiple inner support members 310 to abut against the inner wall surface of the superconducting coil 10, so as to fix the superconducting coil 10 by the inner support assembly 300 (as shown).Figure 6 As shown, at this time, the superconducting coil 10 is connected to the connecting plate 200 and the inner support assembly 300, i.e., the superconducting coil 10 is in the third connection state; further, multiple first fasteners are removed, so that the connecting plate 200 and the superconducting coil 10 are in a non-connected state, at which point the superconducting coil 10 is in the second connection state (e.g., Figure 9 (As shown). In the second connection state, the superconducting coil 10 is parallel to and attached to the side of the coil frame 20 along its height direction on one of its other surfaces; finally, the superconducting coil 10 is directly fixed to the side of the coil frame 20 by a plurality of second fasteners, that is, the superconducting coil 10 and the side wall of the coil frame 20 are detachably fixedly connected by a plurality of coil mounting holes 11, a plurality of coil frame fixing holes 21, and a plurality of second fasteners, each second fastener passing through the corresponding coil frame fixing hole 21 and threadedly connected to the corresponding coil mounting hole 11. It should be noted that the second fasteners and the first fasteners can be different fasteners or the same fasteners. The first fasteners and the second fasteners can be bolts, nut assemblies, or other threaded connectors and nut assemblies.

[0064] The superconducting coil 10 is fixed by the inner support assembly 300, and there is no relative sliding between the inner support members 310 and the inner wall surface of the superconducting coil 10. Similarly, the superconducting coil 10 is fixed by the connecting plate 200, and there is also no relative sliding between the connecting plate 200 and the superconducting coil 10. Therefore, damage to the superconducting coil 10 can be avoided. Furthermore, during the rotation of the assembly fixture 30 and the superconducting coil 10, the superconducting coil 10 is threadedly connected to the connecting plate 200, ensuring safety throughout the rotation process. When the superconducting coil 10 is fixed to the side of the coil frame 20 with fasteners, it remains firmly connected to the inner support assembly 300 of the assembly fixture 30, ensuring a secure connection and eliminating the risk of the superconducting coil 10 falling off during the entire installation process, thus guaranteeing safety. In addition, since multiple inner support members 310 abut against the inner wall surface of the superconducting coil 10, one of the other surfaces of the superconducting coil 10 along its height direction can be completely fitted with the side of the coil frame 20. Therefore, the superconducting coil 10 can be directly and quickly fixed to the side of the coil frame 20 by fasteners, which is convenient and efficient for installation.

[0065] In one embodiment of this utility model, such as Figure 4 , Figure 5 and Figure 10 As shown, the pushing component includes: multiple connecting rod assemblies 320, a sliding rod 330, and a locking member 340; the multiple connecting rod assemblies 320 are correspondingly arranged with multiple inner support members 310; the sliding rod 330 is slidably connected to the connecting plate 200, and the length direction of the sliding rod 330 is parallel to the thickness direction of the connecting plate 200. Figure 4 andFigure 5 (in the C direction). Multiple connecting rod groups 320 are spaced apart on the outer periphery of the sliding rod 330. One end of each connecting rod group 320 is threaded to the outer wall of the sliding rod 330 via a first threaded connector 350, and the other end is threaded to the corresponding inner support member 310 via a second threaded connector 360. The first threaded connector 350 can switch between a first tightened state and a first loose state. When the first threaded connector 350 is in the first tightened state (i.e., when the first threaded connector 350 is tightened), one end of each connecting rod group 320 is fixedly connected to the outer wall of the sliding rod 330; when the first threaded connector 350 is in the first loose state (i.e., when the first threaded connector 350 is loosened), one end of each connecting rod group 320 can rotate relative to the outer wall of the sliding rod 330; the second threaded connector 360 can switch between a first tightened state and a first loose state. Switching between a second tightened state and a second loose state, when the second threaded connector 360 is in the second tightened state (i.e., when the second threaded connector 360 is tightened), the other end of each connecting rod assembly 320 is fixedly connected to the corresponding inner support 310. When the second threaded connector 360 is in the second loose state (i.e., when the second threaded connector 360 is loosened), the other end of each connecting rod assembly 320 can rotate relative to the corresponding inner support 310; one end of each inner support 310 is slidably connected to the connecting plate 200.

[0066] Specifically, when the first threaded connector 350 is in a first unfastened state and the second threaded connector 360 is in a second unfastened state, the sliding rod 330 moves along the thickness direction of the connecting plate 200 ( Figure 4 and Figure 5 The sliding rod 330 (parallel to the length direction of the sliding rod 330) slides relative to the connecting plate 200, which can drive multiple connecting rod assemblies 320 to rotate relative to the sliding rod 330 (the axis of relative rotation is perpendicular to the length direction of the sliding rod 330), and link multiple inner support members 310 to move relative to the connecting plate 200 along the radial direction of the superconducting coil 10. When the multiple inner support members 310 abut against the inner wall surface of the superconducting coil 10, the sliding rod 330 can be locked and fixed to the connecting plate 200 by the locking member 340, and the first threaded connector 350 is in a first fastened state and the second threaded connector 360 is in a second fastened state, so as to fix the superconducting coil 10 by the inner support assembly 300. This can achieve the stability of the abutment between each inner support member 310 and the inner wall surface of the superconducting coil 10, so as to ensure the firm connection between the inner support assembly 300 and the superconducting coil 10, thereby ensuring the safety of installation.

[0067] It should be noted that the locking element 340 can be a single unit or multiple units spaced apart circumferentially along the sliding rod 330. The locking element 340 can be a screw, which passes through the sliding rod 330 and abuts against the connecting plate 200 to lock the sliding rod 330 and the connecting plate 200. The locking element 340 can also be a matching groove and protrusion structure, respectively provided on the sliding rod 330 and the connecting plate 200. When multiple inner support members 310 abut against the inner wall of the superconducting coil 10, the groove and protrusion engage to lock the sliding rod 330 and the connecting plate 200. The locking element 340 can also be other locking structures, as long as they can lock the sliding rod 330 and the connecting plate 200. The first threaded connector 350 and the second threaded connector 360 can be screws or other structures with external threads.

[0068] In one embodiment of this utility model, such as Figure 5 As shown, the second surface 220 of the connecting plate 200 is provided with a protruding annular boss 370, which is sleeved on the outer periphery of the sliding rod 330.

[0069] When multiple inner support members 310 abut against the inner wall of the superconducting coil 10, the locking member 340 passes through the side wall of the annular boss 370 and abuts against the outer wall of the sliding rod 330, locking the sliding rod 330 to the annular boss 370. This locks the sliding rod 330 to the connecting plate 200. This locking mechanism ensures the stability of the contact between the multiple inner support members 310 and the inner wall of the superconducting coil 10.

[0070] like Figure 10 and Figure 11 As shown, the inner support member 310 includes a first abutting plate 311, a second abutting plate 312, and an elastic pad 313 fixedly covering the second abutting plate 312, in the superconducting coil 10 ( Figure 10 and Figure 11 In the radial direction (not shown), one end of the first abutment plate 311 is threadedly connected to the other end of the corresponding connecting rod assembly 320 via a second threaded connector 360, and the other end is fixedly connected to the second abutment plate 312. Figure 4 As shown, in the thickness direction of the connecting plate 200, the end of the first abutting plate 311 near the first surface 210 is slidably connected to the connecting plate 200, and the elastic pad 313 is used to abut against the superconducting coil 10. Figure 4 The inner wall surface (not shown in the diagram). This not only reduces wear on the superconducting coil 10, but also enhances connection reliability by utilizing the elastic rebound force of the elastic pad 313.

[0071] It should be noted that in this embodiment, the elastic pad 313 is made of an elastic material, which can be silicone rubber.

[0072] In one embodiment of this utility model, such as Figure 12 and Figure 13 As shown, the connecting plate 200 has sliding holes 240 and multiple sliding grooves 250. The sliding holes 240 and each sliding groove 250 extend from the first surface 210 to the second surface 220, as shown... Figures 10-14 As shown, the sliding hole 240 is adapted to the sliding rod 330. Multiple sliding grooves 250 are spaced apart on the outer periphery of the sliding hole 240 and correspond one-to-one with multiple inner support members 310. Each sliding groove 250 gradually moves away from the sliding hole 240 radially from one end to the other along its length. Multiple connecting holes 230 are located on the outer periphery of the multiple sliding grooves 250. Each inner support member 310 has an extension member 314 at one end near the first surface 210. The extension member 314 extends along the thickness direction of the connecting plate 200 to pass through... The corresponding slide groove 250, each extension 314 is provided with a sliding bearing 315 at one end away from the corresponding inner support 310, and each sliding bearing 315 is slidably connected to the second surface 220; the sliding rod 330 is slidably connected to the connecting plate 200 through the sliding hole 240; each connecting rod group 320 includes two parallel connecting rods, and the two ends of each connecting rod are respectively threaded to the outer wall of the sliding rod 330 through each first threaded connector 350 and threaded to the corresponding inner support 310 through the second threaded connector 360.

[0073] Specifically, such as Figure 12 and Figure 13 As shown, the connecting plate 200 also has multiple fan-shaped notches, which reduces its weight and facilitates the rotation of the assembly fixture 30. Figure 15 As shown, the sliding rod 330 includes a sliding rod body 331 and a plurality of connecting ears 332 disposed on the outer periphery of the sliding rod body 331, each connecting ear 332 having a threaded hole. A first threaded connector 350 passes through the corresponding threaded hole and is threadedly connected to each connecting rod.

[0074] In one embodiment of this utility model, such as Figure 3 and Figure 16 As shown, the support frame 100 is L-shaped and includes a first frame 110 and a second frame 120 that are perpendicular to each other; one end of the first frame 110 is fixedly connected to one end of the second frame 120; the connecting plate 200 is fixed on the outer side of the first frame 110 along its thickness direction (i.e., on the side of the first frame 110 away from the second frame 120 in its thickness direction).

[0075] It should be noted that the perpendicularity of the first frame 110 and the second frame 120 refers to the thickness direction of the first frame 110. Figure 16 The C direction in the middle is perpendicular to the thickness direction of the second frame 120. Figure 16The plane containing the first frame 110 and the plane containing the second frame 120 are perpendicular to each other (direction D in the diagram). In this embodiment, the fixed connection includes, but is not limited to, welding, integral molding, and threaded connection. The second surface 220 of the connecting plate 200 is close to and abuts against the outer side of the first frame 110 along its thickness direction.

[0076] Because during the process of switching the superconducting coil 10 from a horizontally placed position on the support surface to a vertically suspended position using the assembly fixture 30, and installing it onto the side of the coil frame 20, it is first necessary to align the first surface 210 of the connecting plate 200 parallel to and abut against one of the surfaces of the superconducting coil 10 along its height direction (e.g., ...). Figure 7 The upper surface of the support frame 100 is used to fix the connecting plate 200 and the superconducting coil 10. The first frame 110 is parallel to the support surface, and the second frame 120 is perpendicular to the support surface. The connecting plate 200 and the superconducting coil 10 are then rotated to assemble the fixture 30 and the superconducting coil 10, ensuring the superconducting coil 10 is in a vertically suspended state. Specifically, the plane containing the connecting plate 200, the superconducting coil 10, and the first frame 110 is perpendicular to the support surface, while the plane containing the second frame 120 is parallel to the support surface. By setting the support frame 100 to an L-shape and fixing the connecting plate 200 to the outer side of the first frame 110 along its thickness direction, after the connecting plate 200 and the superconducting coil 10 are connected, the space required for rotating the assembly fixture 30 and the superconducting coil 10 is only the space for placing the superconducting coil 10. The flipping operation can also be completed within this space, enabling operation in confined spaces and saving installation space. Furthermore, the support frame 100 has a simple structure, reducing the manufacturing cost and time cost of the fixture.

[0077] In one embodiment of this utility model, such as Figure 16 As shown, the support frame 100 also includes a reinforcing rod 130, which is located along the thickness direction of the first frame 110. Figure 16 The inner side of the first frame 110 along its thickness direction (in the C direction) (i.e., the side of the first frame 110 close to the second frame 120). Figure 16 The right side of the first frame 110), and the second frame 120 along its thickness direction ( Figure 16 The inner side of the second frame 120 (in the direction of D) (i.e., the side of the second frame 120 close to the first frame 110 along its thickness direction). Figure 16 The reinforcing rod 130 is located on the lower side of the second frame 120, and its two ends are fixedly connected to the first frame 110 and the second frame 120, respectively. By setting the reinforcing rod 130, the strength of the support frame 100 can be increased.

[0078] In one embodiment of this utility model, such as Figure 16As shown, the support frame 100 also includes a lifting lug assembly, which includes a plurality of first lifting lugs 140 and a plurality of second lifting lugs 150. Each of the plurality of first lifting lugs 140 is fixed to the end of the first frame 110 near the second frame 120 and extends along the thickness direction of the second frame 120. Each of the plurality of second lifting lugs 150 has one end fixed to the end of the first frame 110 away from the second frame 120 and the end of the second frame 120 away from the first frame 110, and extends along the thickness direction of the first frame 110. By providing the lifting lug assembly, it is convenient to lift the assembly fixture 30.

[0079] In one embodiment of this utility model, such as Figure 3 As shown, the assembly fixture 30 also includes a counterweight fixed to the second frame 120; the counterweight includes a weight assembly 400 and an adjustment assembly 500, the weight assembly 400 being fixed to the second frame 120 along its thickness direction. Figure 3 The outer side of the D direction in the middle (i.e. Figure 3 (upper side of the first frame 110), the adjusting component 500 is along the thickness direction of the first frame 110 ( Figure 3 (in the C direction) it is slidably connected to the inner side of the second frame 120.

[0080] Since the support frame 100 is L-shaped, after the connecting plate 200 is connected to the superconducting coil 10, it cannot maintain balance when the superconducting coil 10 and the assembly fixture 30 are flipped to a vertically suspended state. By setting a weight assembly 400 on the outside of the second frame 120, the superconducting coil 10 and the assembly fixture 30 can maintain balance in the vertically suspended state. Furthermore, by setting an adjustment assembly 500 on the inside of the second frame 120, and the adjustment assembly 500 can slide along the thickness direction of the first frame 110, the vertically suspended state of the superconducting coil 10 and the assembly fixture 30 can be moderately adjusted so that one of the surfaces of the superconducting coil 10 along its height direction (i.e., the surface opposite to the surface where the superconducting coil 10 is connected to the connecting plate 200) is parallel to the side of the coil frame 20 and can be completely fitted, so as to facilitate the quick fixation of the superconducting coil 10 to the side of the coil frame 20.

[0081] In one embodiment of this utility model, such as Figure 3 and Figure 17 As shown, the weight assembly 400 includes a weight body 410 and a support plate 420. The support plate 420 is fixed to the outside of the second frame 120. The support plate 420 has multiple columnar protrusions 421 extending outwards from the second frame 120 along the thickness direction of the first frame 110. The weight body 410 is located within the area formed by the multiple columnar protrusions 421 on the support plate 420. This restricts the movement of the weight body 410 on the support plate 420, ensuring safety during installation.

[0082] It should be noted that the number of support plates 420 can be set to one, or as follows: Figure 3 The example shows two weights, but more can be used; this embodiment does not impose a specific limitation. The number of weight bodies 410 can be one, or as shown... Figure 3 The example shown shows two weights, but more can be used. If there are two or more weight bodies 410, they can all be located on one support plate 420, or one weight body 410 can be placed on one support plate 420. The weight of the weight body 410 can be selected according to actual needs, as long as the rotated superconducting coil 10 and the assembly fixture 30 can remain balanced. The weight body 410 can be a readily available finished product, eliminating the need for separate manufacturing and reducing the manufacturing cost and time cost of the assembly fixture 30.

[0083] In one embodiment of this utility model, such as Figure 18 As shown, the adjustment assembly 500 includes a slide rail 510, a slider 520, a counterweight plate 530, and a dumbbell 540; the slide rail 510 is fixed to the second frame 120 along its thickness direction. Figure 18 Inside the D direction of the first frame 110, and along the thickness direction of the first frame 110. Figure 18 The dumbbell 540 is fixed on the counterweight plate 530. The counterweight plate 530 is fixedly connected to the slider 520. The slider 520 is adapted to the slide rail 510 and is slidably connected to the slide rail 510 along the extension direction of the slide rail 510 (i.e., the thickness direction of the first frame 110).

[0084] It should be noted that the number of slide rail 510 and slider 520 can be one, or multiple. Figure 16 The two shown can be set to more as needed.

[0085] Specifically, the dumbbell 540, via the slider 520 and slide rail 510, can slide along the thickness direction of the first frame 110 on the inner side of the second frame 120. This allows adjustment of the dumbbell 540's position along the thickness direction of the first frame 110, ensuring that another surface of the superconducting coil 10 along its height direction (i.e., the surface opposite to the surface where the superconducting coil 10 connects to the connecting plate 200) is parallel to and fully fitted with the side of the coil holder 20. This facilitates the subsequent rapid fixing of the superconducting coil 10 to the side of the coil holder 20. It should be noted that the number and weight of the dumbbells 540 can be selected according to actual needs, as long as it ensures that the superconducting coil 10 and the assembly fixture 30 maintain good balance in a vertically suspended state.

[0086] In one embodiment of this utility model, such as Figure 18 and Figure 19As shown, the adjusting assembly 500 also includes a threaded shaft 550 and two shaft clips 560. The threaded shaft 550 is fixed to the counterweight plate 530, with both ends extending out of the counterweight plate 530. The dumbbell 540 is sleeved on the threaded shaft 550, and the two shaft clips 560 are respectively fixed to the two ends of the threaded shaft 550. The dumbbell 540 being sleeved on the threaded shaft 550 prevents radial displacement of the dumbbell 540. The two shaft clips 560 are detachably fixed to the two ends of the threaded shaft 550 to prevent the dumbbell 540 from falling off during sliding, ensuring installation safety and facilitating the replacement of the dumbbell 540.

[0087] Specifically, the top of the counterweight plate 530 is fixedly connected to the slider 520, and the bottom is fixedly connected to the threaded shaft 550.

[0088] The specific assembly process of another assembly method for the superconducting coil 10 is as follows: The superconducting coil 10 is placed horizontally on the support surface (at this time, the height direction of the superconducting coil 10 is perpendicular to the support surface). The hook of the crane can be fixed on all or part of the second lifting lugs 150. The assembly fixture 30 (at this time, the weight body 410 is not placed) is lifted to directly above the superconducting coil 10 (e.g., Figure 7As shown, the plane of the first frame 110 is parallel to the support surface, and the plane of the second frame 120 is perpendicular to the support surface. The crane is operated to lower the assembly fixture 30 vertically, and the connecting plate 200 and the superconducting coil 10 are fixedly connected using multiple first fasteners. After lifting the assembly fixture 30 and the superconducting coil 10 slightly away from the support surface, a section of nylon cable is fixed to one of the second lifting lugs 150 on the second frame 120. By pulling the nylon cable, the assembly fixture 30 and the superconducting coil 10 are flipped until the height direction of the superconducting coil 10 is approximately parallel to the support surface (at this time, the plane of the first frame 110 is approximately perpendicular to the support surface, and the plane of the second frame 120 is approximately parallel to the support surface). A weight body 410 (e.g., a lock-type cast iron weight) is placed on the support plate 420 of the second frame 120, and the second frame 120 is slowly slid... The inner adjustment component 500 is adjusted by adding or removing the counterweight of the dumbbell 540 until the nylon rope is no longer needed to pull. At this time, the superconducting coil 10 is in a vertically suspended state (the height direction of the superconducting coil 10 is parallel to the support surface, the plane where the first frame 110 is located is perpendicular to the support surface, and the plane where the second frame 120 is located is parallel to the support surface). The assembly fixture 30 and the superconducting coil 10 are flipped. The space required for this process is only the space for placing the superconducting coil 10. The flipping operation can also be completed in this space, and the leveling after flipping is achieved with the help of the adjustment component 500. Subsequently, the inner support assembly 300 is fixedly connected to the first lifting lug 140 and the second lifting lug 150 on the second frame 120 via the crane lifting ring. The inner support assembly 300 is adjusted, and the sliding rod 330 slides relative to the connecting plate 200 along the thickness direction of the connecting plate 200, causing multiple connecting rod groups 320 to rotate relative to the sliding rod 330. This, in turn, moves multiple inner support members 310 relative to the connecting plate 200 along the radial direction of the superconducting coil 10, causing the multiple inner support members 310 to abut against the inner wall surface of the superconducting coil 10. The locking member 340 then locks the sliding rod 330 to the connecting plate 200. The first threaded connector 350 connecting each connecting rod group 320 to the outer wall of the sliding rod 330, and the second threaded connector 360 connecting each connecting rod group 320 to the corresponding inner support member 310 are tightened, thus fixing the inner support assembly 300 to the superconducting coil 10. Multiple first fasteners are then removed, leaving the connecting plate 200 and the superconducting coil 10 in a non-connected state. At this point, one of the other surfaces of the superconducting coil 10 along its height direction can be tightly fitted to the side of the coil frame 20, and can be detachably fixed to the side wall of the coil frame 20 by multiple second fasteners, thus completing the side mounting of the superconducting coil 10.

[0089] This utility model also provides an assembly method for a magnetically pulled single-crystal superconducting coil, which is performed based on the above-mentioned assembly fixture for the magnetically pulled single-crystal superconducting coil; the assembly method includes:

[0090] S1: The superconducting coil 10 is placed horizontally on the support surface, and the assembly fixture 30 is suspended above the superconducting coil 10 (e.g.,Figure 7 As shown, the superconducting coil 10 is in a state of being ready to be connected at this time; rotate and move the assembly fixture 30 so that the connecting plate 200 and the inner support assembly 300 are oriented toward the superconducting coil 10 along its height direction ( Figure 7 One of the surfaces (e.g., in direction A) Figure 7 As shown), and the first surface 210 of the connecting plate 200 is aligned with one of the surfaces of the superconducting coil 10 (as shown). Figure 7 The upper surface of the superconducting coil 10 is parallel and in contact with it.

[0091] It should be noted that the supporting surface can be the ground or other planes.

[0092] S2: The connecting plate 200 and the superconducting coil 10 are detachably fixedly connected by multiple connecting holes 230 of the connecting plate 200, multiple coil mounting holes 11 of the superconducting coil 10, and multiple first fasteners. Each first fastener passes through the corresponding connecting hole 230 and is threadedly connected to the corresponding coil mounting hole 11, and the multiple inner support members 310 have a gap with the inner wall surface of the superconducting coil 10 in the radial direction of the superconducting coil 10. At this time, the superconducting coil 10 is in the first connection state.

[0093] S3: Rotate the assembly fixture 30 and the superconducting coil 10 so that the superconducting coil 10 and the connecting plate 200 are perpendicular to the support surface (the height direction of the superconducting coil 10 and the thickness direction of the connecting plate 200 are both parallel to the support surface), and the superconducting coil 10 is in a vertically suspended state (e.g., Figure 8 (As shown). During the rotation of the assembly fixture 30 and the superconducting coil 10, the superconducting coil 10 is connected to the connecting plate 200 by threads, which ensures the safety of the entire rotation process. At the same time, since there is no relative sliding between the connecting plate 200 and the superconducting coil 10, damage to the superconducting coil 10 can be avoided.

[0094] S4: By pushing the pusher component, multiple inner support members 310 are moved radially along the superconducting coil 10, causing the multiple inner support members 310 to abut against the inner wall surface of the superconducting coil 10, thereby fixing the superconducting coil through the inner support assembly 300. At this time, the superconducting coil 10 is in the third connection state (i.e., as shown in the image). Figure 6 As shown, at this time, the superconducting coil 10 is connected to the connecting plate 200 and the inner support assembly 300; multiple first fasteners are removed to make the superconducting coil 10 and the connecting plate 200 disconnected, at which time the superconducting coil 10 is in the second connected state (as shown). Figure 9 As shown, the superconducting coil 10 is in a vertically suspended state and is only fixedly connected to the inner support assembly 300.

[0095] It should be noted that the specific structure of the pushing component is the structure described in Embodiment 1, and this embodiment will not elaborate on it further. To ensure a stable connection between the inner support assembly 300 and the inner wall of the superconducting coil 10, the number of inner support members 310 is at least two, specifically as follows: Figure 6 The four shown.

[0096] S5: When the superconducting coil 10 is in the second connection state (e.g.) Figure 9 As shown, the assembly fixture 30 and the superconducting coil 10 are moved so that the superconducting coil 10 is positioned along its height direction on one of its other surfaces (referred to as the mounting surface with respect to the coil frame 20, which is the surface that contacts the connecting plate 200, i.e.) Figure 7 The lower surface of the superconducting coil 10 is parallel to and in contact with the side wall of the coil frame 20. The superconducting coil 10 is detachably fixed to the side wall of the coil frame 20 through multiple coil mounting holes 11, multiple coil frame fixing holes 21, and multiple second fasteners. Each second fastener passes through the corresponding coil frame fixing hole 21 and is threaded to the corresponding coil mounting hole 11.

[0097] It should be noted that the second fastener and the first fastener can be the same fastener or different fasteners. The fastener can be a bolt, nut assembly, or other assembly that can achieve a threaded connection.

[0098] S6: By pushing the component in the opposite direction, multiple inner support members 310 are moved in the radial direction of the superconducting coil 10, so that there is a gap between the multiple inner support members 310 and the inner wall of the superconducting coil 10 in the radial direction of the superconducting coil 10. At this time, the superconducting coil 10 is not connected to the assembly fixture 30, but is connected to the side of the coil frame 20, thus completing the assembly of the superconducting coil 10 to the side of the coil frame 20.

[0099] During the process of fixing the superconducting coil 10 to the side of the coil frame 20 using the second fastener, since the superconducting coil 10 remains fixedly connected to the inner support assembly 300 of the assembly fixture 30 (the superconducting coil 10 is in the second connection state), the superconducting coil 10 is always firmly connected to the assembly fixture 30. Therefore, there is no risk of the superconducting coil 10 falling off during the entire installation process, ensuring the safety of the entire installation process. In addition, since the multiple inner support members 310 abut against the inner wall surface of the superconducting coil 10, one of the surfaces of the superconducting coil 10 along its height direction (i.e., the mounting surface with the coil frame 20) can be completely fitted with the side of the coil frame 20. Therefore, the superconducting coil 10 can be directly and quickly fixed to the side of the coil frame 20 using the second fastener, which is convenient and efficient. At the same time, since there is no relative sliding between the inner support members 310 and the inner wall surface of the superconducting coil 10, damage to the superconducting coil 10 can also be avoided.
