[0032] To better understand the assembly apparatus for stellarator superconducting coils provided in this application, the specific structure of the assembly apparatus will be described in detail below with reference to the accompanying drawings.

[0033] This invention provides an assembly device for a stellarator superconducting coil, such as... Figure 1 As shown, the device includes a support frame 10 and a flipping assembly 11. The support frame 10 is used to support the device on a support surface, such as the ground or a mobile device. The flipping assembly 11 is mounted on the support frame 10, meaning that the support frame 10 provides support for the flipping assembly 11, and the flipping assembly 11 is used to fix, flip, and rotate the superconducting coil 2. The specific structures of the flipping assembly 11 and the support frame 10 will be described in detail below.

[0034] like Figures 1-2 As shown, the flipping assembly 11 includes a flipping bracket 111 and a flipping drive mechanism 112. The flipping bracket 111 includes a rotating frame 1111 and an annular coil mounting frame 1112 for mounting the superconducting coil 2, which surrounds the outer periphery of the superconducting coil 2, i.e., the superconducting coil 2 is mounted within the annular coil mounting frame 1112. The size of the coil mounting frame 1112 matches the superconducting coil 2, and the superconducting coil 2 is detachably connected to the coil mounting frame 1112. The coil mounting frame 1112 is fixedly connected to the rotating frame 1111, but for ease of installation, the coil mounting frame 1112 and the rotating frame 1111 are detachably connected. The rotating frame 1111 is rotatably connected to the support frame 10 about the first axis A. The rotating frame 1111 can rotate relative to the support frame 10 to adjust the opening angle of the flipping bracket 111 relative to the support frame 10, so that the thickness direction of the coil mounting frame 1112 is relative to the height direction of the support frame 10. Figure 1The angle of the tilt in the Z direction can be adjusted, thereby providing a coil overturning function in the process of assembling the superconducting coil 2. The direction in which the first axis A is located is perpendicular to the height direction of the support frame 10 (the Z direction) Figure 1 in the Z direction.

[0035] Specifically, the structure of the rotating frame 1111 is adapted to the coil mounting frame 1112, as long as the coil mounting frame 1112 can be stably and fixedly connected, and specifically can be as shown in Figures 1-2 The rotating frame 1111 is a frame structure, including a rotating arm and two mounting arms respectively connected to both ends of the rotating arm, the rotating arm is rotatably mounted on the support frame 10, and the outer periphery of the coil mounting frame 1112 is fixedly connected to the two mounting arms through a fixing pin or the like, so that the coil mounting frame 1112 can rotate with the mounting arms of the rotating frame 1111.

[0036] The overturning driving mechanism 112 is in transmission connection with the rotating frame 1111 and is used for driving the rotating frame 1111 to rotate relative to the support frame 10; the overturning driving mechanism 112 is arranged as long as it can drive the rotating frame 1111 to rotate around the first axis A. The overturning driving mechanism 112 can specifically be a motor or other rotatable driving member, one end of the rotating arm is connected to the output shaft of the motor, the output shaft is rotated to drive the rotating arm to rotate, the rotating arm drives the mounting arm to rotate, and the rotating frame 1111 as a whole is rotated.

[0037] The overturning driving mechanism 112 can also be arranged to include a slidable structure, a moving structure and a transmission connecting rod structure, the slidable structure is connected to the support frame 10, the moving structure is in slidable connection with the slidable structure, so that the moving structure can slide along the support frame 10; one end of the transmission structure is in rotatable connection with the moving structure, and the other end is in rotatable connection with the mounting arm of the rotating frame 1111; the moving structure slides along the support table, and the rotating frame 1111 and the coil mounting frame 1112 are driven to rotate relative to the support table through the transmission structure. The slidable structure can specifically include one or a combination of several kinds of slidable structures such as a sliding rail, a lead screw and a hydraulic cylinder.

[0038] In a specific embodiment, as shown in Figure 1 and Figure 2 The overturning driving mechanism 112 includes a driver 1121, a lead screw 1122, a moving block 1123 and a transmission connecting rod 1124; the driver 1121 can specifically be a motor, and correspondingly, a recess structure matched with the driver 1121 can be arranged on the upper part of the support frame 10 to adapt to the installation of the driver 1121, and the driver 1121 can be installed on the upper part of the support frame 10 through a fastening bolt; the lead screw 1122 is arranged on the upper part of the support frame 10 and extends in the first direction (the X direction) Figure 1Extending in the X direction, the end of the lead screw 1122 away from the flipping bracket 111 is connected to the driver 1121 for transmission, so that the driver 1121 drives the lead screw 1122 to rotate. Specifically, the lead screw 1122 can be connected to the support frame 10 through two lead screw fixing seats 1125. One lead screw fixing seat 1125 is installed near the flipping bracket 111, and the other lead screw fixing seat 1125 is installed near the driver 1121. Each lead screw fixing seat 1125 can be fastened to the upper part of the support frame 10 by bolts. The lead screw 1122 and the driver 1121 can be connected by a coupling. In the first direction... The moving block 1123 is slidably connected to the support frame 10 along the first direction and is connected to the lead screw 1122 for transmission, so that the moving block 1123 moves relative to the support frame 10 along the first direction through the rotation of the lead screw 1122; one end of the transmission link 1124 is rotatably connected to the moving block 1123 around the second axis B, and the other end is rotatably connected to the rotating frame 1111 around the third axis C, so that the movement of the moving block 1123 along the first direction is linked to the rotation of the transmission link 1124, and the rotation of the rotating frame 1111 relative to the support frame 10 is driven by the transmission link 1124.

[0039] In another specific implementation, such as Figure 1 and Figure 2 As shown, the tilting drive mechanism 112 includes at least one slide rail 1126, a moving block 1123, and a transmission link 1124. Each slide rail 1126 is fixedly connected to the upper part of the support frame 10 and extends along a first direction ( Figure 1 The moving block 1123 extends in the X direction and can be bolted to the upper part of the support frame 10. It is slidably connected to the slide rail 1126 and can slide along the slide rail 1126. One end of the transmission link 1124 is rotatably connected to the moving block 1123 about the second axis B, and the other end is rotatably connected to the rotating frame 1111 about the third axis C. This allows the moving block 1123 to move in the first direction, which in turn drives the rotating frame 1111 to rotate relative to the support frame 10. Correspondingly, the moving block 1123 can be driven to slide manually or by other driving structures. A locking structure can also be provided on the slide rail 1126 to restrict the sliding of the moving block 1123 relative to the slide rail 1126 when locked. The second axis B and the third axis C are both parallel to the first axis A; the direction of the first axis A is also perpendicular to the thickness direction of the coil mounting frame 1112.

[0040] Furthermore, in the third embodiment, such as Figure 1 and Figure 2As shown, the flipping drive mechanism 112 includes a driver 1121, a lead screw 1122, two slide rails 1126, a moving block 1123, and transmission connecting rods 1124. The two slide rails 1126 are respectively disposed on both sides of the lead screw 1122 and are parallel to the lead screw 1122. The two ends of the moving block 1123 are slidably connected to the two slide rails 1126, and the middle part of the moving block 1123 is rotatably connected to the lead screw 1122. There are two transmission connecting rods 1124: one end of one transmission connecting rod is connected to the first end of the moving block 1123, and the other end is connected to the mounting arm on the rotating frame 1111 corresponding to the first end; the other transmission connecting rod is connected to the second end of the moving block 1123, and the other end is connected to the mounting arm on the rotating frame 1111 corresponding to the second end. The moving block 1123 may specifically include a main body and a sliding connection structure. Figure 1 and 2 The lower part of the moving block 1123 is connected to the lead screw 1122. Both ends of the moving block 1123 are slidably connected to two slide rails 1126. Triangular supports are welded to both ends of the side of the main body away from the lead screw 1122, respectively, for rotatable connection to one end of a transmission link 1124. The sliding connection structure has threaded holes for fitting around the lead screw 1122 for rotatable connection. The outer side of the sliding connection structure is fixedly connected to the middle of the main body by bolts. Triangular supports can also be installed on each mounting arm of the rotating frame 1111 for rotatable connection to the other end of the corresponding transmission link 1124.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown, two symmetrically arranged triangular supports can be fixedly connected to the upper surface of the support frame 10 by welding or other means, and a rotating shaft is fixedly connected to each triangular support by welding. The two ends of the rotating arm of the rotating frame 1111 are respectively rotatably connected to the two rotating shafts, so that the rotating arm can rotate around the first axis A. The triangular supports and rotating shafts are both high-strength components, which need to be able to withstand the shear force, friction force and other forces generated by the mutual movement between the components during the rotation of the flipping assembly 11.

[0042] In one specific implementation, such as Figures 1-2 As shown, the flipping assembly 11 also includes at least one track moving member 113, each track moving member 113 being disposed on the peripheral wall of the coil mounting bracket 1112; a groove is provided on the outer periphery of the coil mounting bracket 1112 corresponding to the position of each track moving member 113, the groove extending circumferentially along the coil mounting bracket 1112, and a strip-shaped hole is provided on the inner periphery of the coil mounting bracket 1112 corresponding to the position of the groove, the strip-shaped hole communicating with the groove and extending along the extending direction of the groove; as Figure 3As shown, each track moving component 113 includes a coil fixing block 1131, a connecting post 1132, and a track block 1133. The coil fixing block 1131 is disposed on the inner circumferential surface of the coil mounting bracket 1112 and is used for fixed connection with the superconducting coil 2. The curvature of the side of the coil fixing block 1131 connected to the coil mounting bracket 1112 should be adapted to the inner circumference of the coil mounting bracket 1112 to facilitate fitting the inner circle. The track block 1133 is disposed in the groove and can move along the extension direction of the groove. The connecting post 1132 is used to penetrate through the groove. The superconducting coil 2 has a slotted hole, and the connecting post 1132 is fixedly connected to the coil fixing block 1131 and the track block 1133 respectively. The connecting post 1132 can cooperate with the slotted hole to limit the rotation of the superconducting coil 2 and prevent it from falling off. The track block 1133 moves along the groove, and the connecting post 1132 drives the coil fixing block 1131 to move relative to the coil mounting frame 1112, so that the superconducting coil 2 fixed to each coil fixing block 1131 can rotate relative to the coil mounting frame 1112 in the circumferential direction. The track moving part 113 also provides rotation function for the superconducting coil 2, improves the assembly freedom of the superconducting coil 2, and makes it easier to adjust the installation posture of the superconducting coil 2.

[0043] Furthermore, in one specific implementation, such as Figure 3 As shown, each track moving component 113 also includes multiple pulleys 1134. These pulleys 1134 are positioned on the side of the track block 1133 near the coil fixing block 1131. Each pulley 1134 is rotatably connected to the track block 1133. In the width direction of the groove, the pulleys 1134 are respectively positioned on both sides of the connecting column 1132, specifically symmetrically on both sides. The track block 1133 moves along the groove by the multiple pulleys 1134 rolling on the bottom of the groove. The number of pulleys 1134 can be 2, 4, 6, etc., depending on the strength and size of the pulleys. The symmetrical arrangement of the pulleys 1134 ensures uniform force distribution, guaranteeing stability while allowing the superconducting coil to be rotatably adjusted.

[0044] Furthermore, in one specific implementation, such as Figure 2As shown, there are two track moving parts 113, which are respectively disposed on opposite side walls of the coil mounting bracket 1112. Specifically, they can be installed on the side wall where the coil mounting bracket 1112 connects to the rotating bracket 1111, or they can be installed on the sides of the rotating arm near and away from the rotating bracket 1111, respectively. The outer periphery of each pulley 1134 is made of rubber. The rubber material gives the pulley 1134 a springback allowance, which allows the structure of the track moving part 113 to fit more closely to the outer surface of the coil mounting bracket 1112. The rubber material allows the track moving part 113 to bear the weight without damaging the outer periphery of the coil mounting frame 1112; each strip hole is arc-shaped along its extension direction, and the central angle of the strip hole is 50°-70°, preferably 60°; that is, the arc of the strip hole is 50°-70°. This setting allows the track moving part 113 to make a circumferential movement within a range of 50°-70° along the outer periphery of the coil mounting frame 1112, so that the superconducting coil 2 can rotate within a range of 50°-70° within the coil mounting frame 1112.

[0045] The support frame 10 is a strong and stable support body, and at least at the top has a support structure (such as a support plate of sufficient strength) for connecting and supporting the flipping assembly 11. The support frame 10 can be designed as a simple frame that only provides upward support, such as a table-like structure. The support frame 10 can also be designed as a frame that can move horizontally along a support surface (such as the ground), for example, by providing matching sliding structures on the support frame 10 and the support surface, specifically... Figure 1 and Figure 5 As shown, multiple movable wheels 13 are provided at the bottom of the support frame 10. More specifically, the movable wheels 13 can be omnidirectional rollers, which are fastened to the bottom of the support frame 10 by bolts. The movable wheels 13 roll to drive the support frame 10 to move horizontally along the support surface, so that the flipping component 11 moves synchronously. The multiple movable wheels 13 can specifically be 4, 6, etc. Furthermore, the movable wheels 13 can also be equipped with a braking structure. When the assembly device 1 does not need to be moved or has reached the assembly position, the braking structure is locked to ensure that the assembly device 1 is fixed in place. When the assembly device 1 needs to be pushed, the braking structure is released, and the assembly device 1 is moved manually or by vehicle towing. The movable wheels 13 roll to move the assembly device 1. This configuration gives the assembly device 1 a high degree of freedom of movement, providing X and Y degree of freedom for the assembly of the superconducting coil 2.

[0046] The support frame 10 can also be designed as a frame that can be raised and lowered relative to the support surface. In one specific embodiment, such as... Figure 1 , Figures 4-5 As shown, the support frame 10 includes components along its height direction ( Figure 1A top support 101, a support assembly 102, and a bottom support 103 are stacked in the Z-direction. The support assembly 102 supports the top support 101 to move up and down relative to the bottom support 103 along the height direction of the support frame 10. The support assembly 102 may include a pneumatic cylinder, a hydraulic cylinder, a screw lifting structure, a scissor lifting structure, or other structures capable of lifting. The bottom support 103 is used to support a support surface. Specifically, the bottom support 103 can be directly set on the support surface, or multiple casters 13 can be provided at the lower part of the bottom support 103, or the lower part of the bottom support 103 can be connected to the support surface through a matching sliding structure. A flipping assembly 11 is set on the side of the top support 101 away from the support assembly 102, that is, the upper part of the support frame 10 for setting the flipping assembly 11 is the top support 101.

[0047] This embodiment allows the support frame 10 to rise and fall relative to the support surface, driving the flipping assembly 11 to rise and fall synchronously, providing a height adjustment function for the superconducting coil 2 installed in the coil mounting frame 1112, thereby adjusting the installation height of the superconducting coil 2, improving the assembly freedom of the superconducting coil, and providing a Z-direction degree of freedom for the assembly of the superconducting coil 2.

[0048] In one specific embodiment, the support component 102 includes a scissor lift structure, specifically as follows: Figure 1 , Figure 4 and Figure 5 As shown, the support component 102 includes a second direction ( Figure 1 Two sets of scissor arms 1021 are arranged opposite each other in the Y direction. Each set of scissor arms 1021 includes two scissor plates that are rotatably connected to each other, namely a first scissor plate 10211 and a second scissor plate 10212. The first end (left end in the figure) of the first scissor plate 10211 is rotatably connected to the bottom support 103, and the second end (right end in the figure) is rotatably and slidably connected to the top support 101 in the first direction. The first end (left end in the figure) of the second scissor plate 10212 is rotatably connected to the top support 101, and the second end (right end in the figure) is rotatably and slidably connected to the bottom support 103 in the first direction. In the first direction, the second ends of the two scissor plates of each set of scissor arms 1021 are located on the same side of the first ends of the two scissor plates. The second direction is parallel to the direction where the first axis A is located.

[0049] Specifically, the two sets of scissor arms 1021 have a total of four scissor plates, arranged in pairs. Each set of scissor arms 1021 forms a cross lifting structure along one side of the second direction. The two sets of scissor arms 1021 are parallel and symmetrically arranged. The effect is that when viewed from the two sides of the support frame 10 along the second direction, the two sets of scissor arms 1021 overlap. When viewed from the other two sides of the support frame 10, the two sets of scissor arms 1021 are approximately two straight lines, and the two ends of the two straight lines are respectively close to the inner sides of the edges of the top support seat 101 and the bottom support seat 103. Furthermore, flanges extending along the height direction of the support seat can be provided circumferentially on the edges of the opposite surfaces of the top support seat 101 and the bottom support seat 103. Specifically, square tubes can be connected to the edges of the top support seat 101 and the bottom support seat 103 to form flanges, so that the two sets of scissor arms 1021 are arranged in the space within the flanges. More specifically, each scissor plate is provided with a through hole at both ends and the middle position. The top support 101 and the bottom support 103 are fixedly connected to the flanges on one side (shown as the left side in Figure 1) along the first direction (X direction in Figure 1), respectively. The connection can be made by welding. Each set of scissor arms 1021 passes through the two through holes on one side (i.e., the through holes at the first ends of the first scissor plates 10211 and 10212) through the fixed pins of the top support 101 and the bottom support 103, respectively, so that each set of scissor arms 1021 is rotatably connected to the top support 101 and the bottom support 103 respectively, and will not fall off or get stuck.

[0050] The assembly device 1 also includes a lifting drive mechanism 12, which is connected to two sets of scissor arms 1021. The lifting drive mechanism 12 drives the second ends of the two scissor plates in each set of scissor arms 1021 to slide relative to the bottom support 103 and the top support 101 in a first direction (X direction in Figure 1), causing the top support 101 to rise and fall relative to the bottom support 103 along the height direction of the support frame 10. The lifting drive mechanism 12 can be a hydraulic drive mechanism, using a hydraulic pump to press hydraulic oil into a hydraulic cylinder, pushing the piston rod and thus driving the scissor arms 1021 to achieve lifting action; the lifting drive mechanism 12 can also be an electric drive mechanism, driven by a motor, which drives the scissor arms 1021 to achieve lifting action through a transmission component, specifically a screw drive structure, chain drive structure, or cable drive structure; the drive mechanism can also be a manual drive mechanism, equipped with an operating handle or handwheel, achieving lifting action through a mechanical transmission structure (such as a cable drive structure).

[0051] In one specific implementation, as shown in Figure 1, Figures 4-5As shown, the support assembly 102 also includes a connecting shaft 1022. The two ends of the connecting shaft 1022 are fixedly connected to the intersection of the scissor plates of the two sets of scissor arms 1021, that is, one end of the connecting shaft 1022 is fixedly connected to the intersection of the two scissor plates of one set of scissor arms 1021, and the other end is fixedly connected to the intersection of the two scissor plates of the other set of scissor arms 1021. Specifically, the two scissor plates of each set of scissor arms 1021 are rotatably connected at their intersection, and one of the scissor plates is fixedly connected to the connecting shaft 1022; more specifically, the end of the connecting shaft 1022 can pass through the through hole at the intersection of the two scissor plates of a set of scissor arms 1021 and be fixedly connected to the through hole of the outer scissor plate on the outside of the scissor arm 1021 by welding or other means, and the inner scissor plate can rotate relative to the connecting shaft 1022; alternatively, the intersection of the two scissor plates of a set of scissor arms 1021 can be rotatably connected by a separate rotating shaft, and the end of the connecting shaft 1022 is fixedly connected to the inner scissor plate at the intersection by welding or other means.

[0052] As shown in Figure 1, Figures 4-5 As shown, the lifting drive mechanism 12 includes a winch 121 and a hinge cable 122. The winch 121 is rotatably connected to the top support 101 on the side away from the tilting assembly 11, specifically on the side of the second end of the scissor plate. This arrangement does not interfere with the operating space of the tilting assembly 11, and the top support 101 can provide protection in case the hinge cable 122 breaks or drips grease. The winch 121 and the top support 101 can be fastened together with bolts to firmly fix the winch 121 on the top support 101, ensuring safety and reliability. One end of the hinge cable 122 is wound around the winch 121, and the other end is wound around the connecting shaft 1022. By manually or by motor driving the winch 121 to rotate, the hinge cable 122 is pulled in or out. The hinge cable 122 is linked to the rotation of the connecting shaft 1022, which drives the second ends of the two scissor plates in each set of scissor arms 1021 to slide in the first direction, thereby realizing lifting and lowering.

[0053] In one specific implementation, such as Figure 5As shown, there are two winches 121, namely an electric winch 1211 and a manual winch 1212, which are independently arranged. The axis of the electric winch 1211 is parallel to or on the same straight line as the axis of the manual winch 1212. The connecting shaft 1022 includes a first part and a second part that are connected along its axial direction. In a second direction, the first part overlaps at least partially with the electric winch 1211 and the second part overlaps at least partially with the manual winch 1212. There are two hinge cables 122. One end of the hinge cable 122 is wound around the electric winch 1211 and the other end is wound around the first part of the connecting shaft 1022. One end of the other hinge cable 122 is wound around the manual winch 1212 and the other end is wound around the second part of the connecting shaft 1022. Specifically, two hinged cables 122 are evenly wound and fixed on the first and second parts of the connecting shaft 1022, respectively. The first and second parts are evenly and adjacently distributed on the connecting shaft 1022. The two parts of the connecting shaft 1022 are respectively connected to the winch 121 on the same side through the hinged cables 122. The winch 121 can be made of stainless steel, which has a greater load-bearing capacity.

[0054] The electric winch 1211 and the manual winch 1212 operate synchronously. The rotation of the electric winch 1211 causes the corresponding cable 122 to be wound and unwound, which in turn causes the corresponding cable 122 of the manual winch 1212 to be wound and unwound, thereby driving the manual winch 1212 to rotate. This ensures that the manual winch 1212, the cable 122, and the connecting shaft 1022 form a foolproof design. Figure 5 As shown, the manual winch 1212 and the electric winch 1211 can be fixed adjacent to each other. Further, as... Figure 4 and Figure 5 As shown, the manual winch 1212 is provided with multiple locking holes arranged circumferentially. Locking elements can be inserted into the locking holes to restrict the rotation of the manual winch 1212. After the lifting and lowering movement is completed, the locking elements, such as screws, are fixed to the locking holes of the manual winch 1212 to prevent the manual winch 1212 from continuing to rotate, thus preventing the corresponding cable 122 from continuing to be wound or unwound, and consequently preventing the rotation of the connecting shaft 1022 and the winding and unwound of the other cable 122. This avoids the safety hazards of lifting and lowering caused by accidentally activating the switch of the electric winch 1211 during operation.

[0055] In one specific implementation, such as Figures 4-5As shown, the support assembly 102 also includes a first connecting rod 1023, a second connecting rod 1024, and multiple rollers 1025. The two ends of the first connecting rod 1023 are respectively fixedly connected to the first ends of the first scissor plates 10211 in the two sets of scissor arms 1021. The two ends of the second connecting rod 1024 are respectively fixedly connected to the second ends of the second scissor plates 10212 in the two sets of scissor arms 1021, and are symmetrically arranged with the first connecting rod 1023. Specifically, the first connecting rod 1023 and the second connecting rod 1024 can be welded to the scissor arms 1021, and the first connecting rod 1023 and the second connecting rod 1024 are reinforcing structures of the support assembly 102, which can enhance the strength of the support assembly 102 during lifting and lowering movements, as well as the synchronization and strength of the two sets of scissor arms 1021.

[0056] Furthermore, some of the rollers 1025 are rotatably connected to the second ends of the first scissor plates 10211 in the two sets of scissor arms 1021, and can roll along the first direction on the top support 101; the remaining rollers 1025 are rotatably connected to the second ends of the second scissor plates 10212 in the two sets of scissor arms 1021, and can roll along the first direction on the bottom support 103; specifically, four rollers 1025 can be provided, each rotatably connected to the second end of the corresponding scissor plate. More specifically, a rotating shaft can be used, with one end rotatably connected to the rollers 1025 and the other end connected to the inner side of the second end of the corresponding scissor plate via... The roller 1025 is welded and fixedly connected, and its outer periphery abuts against the top support 101 or the bottom support 103. The rotation of the roller 1025 causes the second end of the corresponding scissor plate to slide along the first direction. Furthermore, a matching guide rail structure can be provided on the outer side of the second end of the corresponding scissor plate and the flange of the top support 101 or the bottom support 103 to guide the sliding direction. The roller 1025 can also be made of rubber material at least on its outer periphery, so that the scissor plate, the connecting shaft 1022 and other structures can slide smoothly within the frame surrounded by the top support 101 and the bottom support 103, thereby allowing the support assembly 102 to rise and fall smoothly. The rubber material of the roller 1025 can also reduce the noise generated when the device rises and falls.

[0057] When using the assembly device provided by the present invention, the superconducting coil 2 is first installed on the coil mounting bracket 1112. If the assembly device 1 also has a track moving part 113, the fixing hole on the superconducting coil 2 is fixedly connected to the coil fixing block 1131 with bolts, so that the connecting column 1132 passes through the strip hole on the coil mounting bracket 1112 and is fixedly connected to the track block 1133 with bolts or the like.

[0058] Install the coil mounting bracket 1112 onto the rotating frame 1111. A crane or other device can be used to assist in the installation. Pass the sling through the top of the inner circle of the coil mounting bracket 1112 and hang the two ends of the sling on the crane hook. Hoist it above the rotating frame 1111 of the assembly device 1. Set the rotating frame 1111 to a vertical position. If the support frame 10 has a lifting function, adjust it to the lowest height. Operate the crane to place the coil mounting bracket 1112 into the rotating frame 1111. Use fixing pins or the like to fix the coil mounting bracket 1112 to the rotating frame 1111. After installation, operate the flipping drive mechanism 112 (specifically, a screw drive structure) to flatten the rotating frame 1111. The preparation stage is now complete.

[0059] Push the assembly device 1 to the installation area. If the support frame 10 has a lifting function, raise the support frame 10 to the installation height. If the support frame 10 includes a scissor arm 1021, an electric winch 1211, and a manual winch 1212, remove the locking device on the manual winch 1212 and start the electric winch 1211 to raise it to the installation height. Operate the flipping drive mechanism 112 to rotate the flipping bracket 111. If the flipping drive mechanism 112 includes a driver 1121, a lead screw 1122, a moving block 1123, and a transmission link 1124, start the driver 1121 (e.g., a motor) to rotate the lead screw 1122, causing the moving block 1123 to slide, so that the flipping bracket 111 rotates to the angle that is just right to fit the target workpiece. If the assembly device 1 also has a track moving part 113, adjust the track moving part 113 to rotate the superconducting coil 2 until the superconducting coil 2 is in the installation position. Insert the locking member into the locking hole to restrict the rotation of the manual winch 1212, and begin the installation of the superconducting coil 2 with the target workpiece. After installation, disconnect the connection between the superconducting coil 2 and the coil mounting bracket 1112, adjust the height and angle of the assembly device 1, and exit the installation area. The installation of the superconducting coil 2 is now complete.
