Description

Technical Field

[0001] The invention relates to the technical field of armored superconducting coils, and in particular to a nuclear fusion armored superconducting coil flipping system and flipping method. Background Art

[0002] The armored superconducting coil is an electromagnetic device that tightly combines superconducting materials with metal armor structures. Compared with NbTi materials, armored superconducting conductors made of Nb3Sn materials are widely used in the field of nuclear fusion due to their higher magnetic field strength. Superconducting coils made of Nb3Sn materials need to undergo heat treatment to exhibit strong superconducting properties, and armored Nb3Sn superconducting coils with external joints need to be flipped after heat treatment before insulation wrapping, so it is necessary to transport and flip the armored Nb3Sn superconducting coils with external joints. In order to make the armored superconducting coil provide a uniform magnetic field density when energized, it is necessary to ensure that the armored superconducting coil cannot be deformed during the coil winding, heat treatment, inter-turn insulation wrapping and stacking processes, that is, the dimensional shape and position tolerances of the entire coil before and after the process treatment need to remain consistent.

[0003] In the existing technology, in the current production and development process, a motor is used to drive the tray structure to rotate, and the electromagnetic coil is combined to adsorb and fasten the clamping plate, and the slide rail, receiving device and industrial computer are used for coordinated control to achieve 180° automatic flipping and receiving of the superconducting coil. Since the system is highly dependent on electromagnetic adsorption, the clamping plate needs to be made of ferromagnetic material, and long-term use may also affect the adsorption stability due to magnetic attenuation. At the same time, the superconducting coil is prone to eddy current heating risks in a strong magnetic field environment; secondly, the mechanical structure has strict requirements on accuracy, and the mechanical matching dimensions such as gear pair transmission and positioning notches are prone to flipping deviations due to processing errors or wear, which in turn affects the operating accuracy, and has poor adaptability to large-sized or heavy superconducting coils.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The embodiment of the present application provides a nuclear fusion armored superconducting coil inverting system and an inverting method, which solve the problems in the prior art that the dependence on electromagnetic adsorption is relatively strong, so the clamping plate needs to be made of ferromagnetic material, and the adsorption stability may be affected by magnetic attenuation after long-term use. At the same time, there is a risk of eddy current heating for superconducting coils in a strong magnetic field environment. Secondly, the mechanical structure has strict precision requirements, and mechanical matching dimensions such as gear pair transmission and positioning notches are prone to inverting deviation due to machining errors or wear, thereby affecting the operation precision, and the adaptability to large-size or heavy superconducting coils is poor. The inverting tooling of the present application adopts a reticular frame structure welded by rectangular tubes, which reduces the overall weight while ensuring the structural strength. By adjusting the height of the lifting points step by step with different lifting equipment, the horizontal placement, vertical inversion, reverse rotation, and horizontal restoration processes of ultra-large or ultra-heavy superconducting coils can be realized, effectively avoiding the overturning risk caused by sudden changes in the center of gravity.

[0021] Specifically, please refer to the following embodiments: Refer to Figures 1 - 6 , an embodiment of a nuclear fusion armored superconducting coil inverting system provided by the present invention, the specific structure includes: an inverting tooling 1 with a split design. By stacking the top cover 11 and the bottom cover 12, a closed fixing cavity can be formed after stacking, and the function of this fixing cavity is to firmly surround and fix the superconducting coil 2 to be inverted. Among them, the top cover 11 and the bottom cover 12 are welded and connected by rectangular tubes to form a reticular frame structure, so that the top cover 11 and the bottom cover 12 can firmly fix and install the ultra-large and ultra-heavy superconducting coil 2 with a shape-preserving tooling 3 after surrounding.

[0022] Specifically, the reticular frame structure is composed of a peripherally closed rectangular support frame 15, forming the basic force-bearing boundary of the flipping tooling 1; in the internal space of the support frame 15, multiple groups of concentric ring-shaped connecting frames 16 are arranged and extended outward to the periphery. These connecting frames 16 are distributed at equal intervals or in a variable-diameter gradient with the geometric center of the tooling as the reference, forming a hierarchical support structure in the shape of "concentric circles"; correspondingly, each group of ring-shaped connecting frames 16 is formed by bending a rectangular pipe, and its outer shape can be adjusted according to the size and weight of the corresponding superconducting coil 2.

[0023] Furthermore, between adjacent hierarchical ring-shaped connecting frames 16, they are rigidly connected through radially distributed support rods 17; and the support rods 17 are made of rectangular pipes of the same specification as the main frame and are welded to the middle positions of the inner and outer ring frames at a preset angle (such as 30°, 45°, 60°, and 90°, etc.), and then a reticular frame structure radiating outward can be formed.

[0024] It can be understood that the reticular frame structures of the top cover 11 and the bottom cover 12 can effectively reduce the weight of the flipping tooling 1, and when the weight of the superconducting coil 2 is transmitted to the frame through the shape-preserving tooling 3, the axial load is evenly diffused layer by layer from the ring-shaped connecting frames 16 to the center and the periphery, and the radial load is converted into the circumferential tension and radial pressure of the ring frame through the radiation structure of the support rods 17, avoiding local stress concentration and meeting the bearing requirements of the dynamic load during the flipping process of the superconducting coil 2.

[0025] Please continue to refer to Figures 1 - 6 , in this embodiment, multiple groups of limit clamps 18 are arranged in the middle of the fixed cavity formed by the support rods 17 of the top cover 11 and the support rods 17 of the bottom cover 12, and are used to cooperate with the shape-preserving tooling 3 to limit and fix the superconducting coil 2.

[0026] Among them, threaded holes for installing the tightening bolts 4 are symmetrically drilled in the middle position of each limit clamp 18, which can assist in tightly fixing the superconducting coil 2; correspondingly, a top backing plate 6 is arranged at the top of the limit clamp 18, and side backing plates 7 are correspondingly arranged on the side of the limit clamp 18 to achieve all-round and multi-dimensional stable limiting of the superconducting coil 2 in the vertical direction (Z-axis) and the radial direction (X / Y-axis), thereby preventing displacement or deformation of the superconducting coil 2 caused by various complex external forces during the flipping process, and finally effectively ensuring that the change value of the contour accuracy is within the specified range.

[0027] Furthermore, two groups of lifting points 13 are symmetrically arranged on the outer sides of the opposite edges of the top cover 11 and the bottom cover 12, so that the flipping tooling 1 can be connected to different lifting equipment (such as cranes and overhead traveling cranes, etc.) through the lifting points 13, and then the flipping and rotation of the superconducting coil 2 can be realized.

[0028] Specifically, the lifting point 13 is composed of a mounting plate 131. The mounting plate 131 is in close contact with the outer end surface of the top cover 11 or the bottom cover 12, and the surface of the mounting plate 131 has been milled to form a positioning groove plate that matches the outer surface of the frame. In addition, a lifting hole 132 is provided on the mounting plate 131, so that the lifting point 13 can be connected to the lifting equipment through a steel wire rope to complete the lifting and placement of the top cover 11. Correspondingly, on the inner sides of the top cover 11 and the bottom cover 12, guide columns 14 that are sleeved and connected to each other are arranged in a symmetrical layout, so that the top cover 11 and the bottom cover 12 can be accurately positioned through the guide columns 14 during assembly.

[0029] It can be understood that during the actual flipping operation process, the inner sides of the top cover 11 and the bottom cover 12 can achieve precise alignment by sleeving the guide columns 14. Subsequently, with the synergistic effect of the limit fixture 18 and the backing plate, the superconducting coil 2 is firmly fixed from multiple dimensions, effectively resisting the risks of displacement or deformation caused by complex working conditions such as vibration and offloading during the flipping process. Subsequently, through the operation process of step-by-step adjusting the height of the lifting point 13, the entire complex flipping process of the super-large or super-heavy superconducting coil 2 from the initial horizontal placement state to the vertical state, then performing flexible rotation and reverse operation, and finally accurately returning to the horizontal state can be smoothly achieved, thereby ensuring the safety and high efficiency of the flipping operation of the superconducting coil 2.

[0030] Please continue to refer to Figures 1 - 6 , in this embodiment, the conformal tooling 3 is composed of an upper cover plate 31, side plates 32, and a lower cover plate 33 that are stacked.

[0031] Similarly, threaded holes are symmetrically provided in the middle of the upper cover plate 31 and the side plates 32, and tightening bolts 4 are installed in the threaded holes. A top backing plate 6 is provided between the upper cover plate 31 and the superconducting coil 2, and a side backing plate 7 is also provided between the side plates 32 and the superconducting coil 2, which can not only closely fit the top and side end surfaces of the superconducting coil 2, but also absorb the minor vibrations caused by external forces to a certain extent, further reducing the risk of damage to the superconducting coil 2 caused by hard friction. In addition, lifting rings 5 are symmetrically installed on both sides of the upper cover plate 31, and then the superconducting coil 2 is lifted and moved through the lifting equipment.

[0032] It should be specifically noted that the material of the backing plate is G10, which is a material composed of glass fiber and epoxy resin, with high hardness, strength, insulation, and corrosion resistance, and can always maintain a stable shape, providing reliable support for the superconducting coil 2 and more effectively ensuring the contour of the superconducting coil 2.

[0033] It can be understood that in practical applications, by evenly tightening the top bolt 4, an all-round and stable pressing force can be formed on the superconducting coil 2. In cooperation with the direct contact between the top backing plate 6 and the side backing plate 7 and the surface of the superconducting coil 2, it can effectively prevent the superconducting coil 2 from being damaged due to hard friction with the tooling components, and effectively ensure that the contour of the superconducting coil 2 during the flipping operation is always maintained within the preset range.

[0034] Referring to Figure 7 , the present invention also provides an embodiment of a method for flipping a fusion - armored superconducting coil 2, which is executed by the fusion - armored superconducting coil 2 flipping system as described in the above - mentioned embodiment. The flipping method includes: S100, inspect and install the flipping tooling 1 on the support platform, and hoist the superconducting coil 2 into the flipping tooling 1; S200, hoist the flipping tooling 1 by different hoisting devices, driving the horizontally placed superconducting coil 2 in the flipping tooling 1 to be erected, rotated, and flipped; S300, remove the flipping tooling 1, and hoist the flipped superconducting coil 2 into the next processing station.

[0035] Please continue to refer to Figure 8 , in this embodiment, S100 includes: S110, connect the hoisting device with the lifting points 13 of the top cover 11 and the bottom cover 12 through a steel wire rope, hoist the bottom cover 12 to the support seat by the hoisting device, and hoist the top cover 11 above the bottom cover 12 by the hoisting device; S120, hoist the superconducting coil 2 installed with the shape - preserving tooling 3 into the bottom cover 12 by the hoisting device, and hoist the top cover 11 and the bottom cover 12 to form a fixed cavity by the hoisting device; S130, install the connecting plate to fix the bottom cover 12 and the top cover 11, and install the limit fixture 18, the top backing plate 6, and the side backing plate 7 to fix the superconducting coil 2.

[0036] It should be elaborated in detail that when performing the operation process of hoisting the superconducting coil 2 into the flipping tooling 1, first connect the hoisting device with the lifting points 13 of the top cover 11 and the bottom cover 12 through a steel wire rope; when operating the hoisting device, first ensure that the bottom cover 12 is stably placed on the support platform, and then operate the hoisting device again to hoist the top cover 11 directly above the bottom cover 12 to prepare for the subsequent enclosure operation; Then, hoist the superconducting coil 2 installed with the shape - preserving tooling 3 into the bottom cover 12 smoothly by another hoisting device. After the placement of the superconducting coil 2 is completed, enclose the top cover 11 and the bottom cover 12 by two different hoisting devices to form a fixed cavity for fixing the superconducting coil 2. When the top cover 11 descends, the precise docking of the top cover 11 and the bottom cover 12 is realized by accurately aligning the guiding columns 14; Subsequently, install the connecting plate to connect the bottom cover 12 and the top cover 11 to enhance the stability of the overall structure. Then, install the limit fixture 18, the top cushion plate 6, and the side cushion plate 7 in sequence. Through the coordinated action of these components, firmly fix the superconducting coil 2 in the flipping tooling 1 to ensure that the superconducting coil 2 will not shift or shake during subsequent operations; Finally, lift the flipping tooling 1 in a horizontal lifting manner and place it steadily on the ground. After placement, check one by one whether the tightening bolts 4 are loose. After marking, re-tighten them. After the tightening bolts 4 are tightened, repeat the above inspection and tightening operations continuously until all bolts no longer show looseness, so as to ensure the safety and stability of the entire flipping tooling 1 during subsequent use.

[0037] Please continue to refer to Figure 9 , in this embodiment, S200 includes: S210, hoist the flipping tooling 1 horizontally placed on the support base to rise in parallel through different hoisting equipment; S220, lower one lifting point 13 on the side of the flipping tooling 1 away from the joint of the superconducting coil 2 by one set of hoisting equipment, and synchronously lift the other lifting point 13 on the side of the flipping tooling 1 close to the joint of the superconducting coil 2 by the other set of hoisting equipment, so that the flipping tooling 1 is axially flipped to be vertically upward; S230, release the connection relationship between the bottom lifting point 13 and the hoisting equipment, rotate the flipping tooling 1 axially by 180°, and restore the connection relationship between the bottom lifting point 13 and the hoisting equipment again; S240, lift one lifting point 13 on the side of the flipping tooling 1 away from the joint of the superconducting coil 2 by one set of hoisting equipment, and synchronously lower the other lifting point 13 on the side of the flipping tooling 1 close to the joint of the superconducting coil 2 by the other set of hoisting equipment, so that the flipping tooling 1 is axially flipped to be horizontally upward; S250, hoist the horizontally placed flipping tooling 1 to descend in parallel to the support base through different hoisting equipment.

[0038] It should be specifically noted that when performing the flipping device of the superconducting coil 2, the hooks of different hoisting equipment (cranes and overhead cranes) are respectively connected to the symmetrically arranged lifting points 13 on both sides of the horizontally placed flipping tooling 1 on the support base, and the hoisting equipment is started at the same time to lift the hooks at a constant speed, so that the flipping tooling 1 rises in parallel; Subsequently, the two sets of hoisting equipment respectively perform the lowering and lifting operations synchronously: the overhead crane slowly lowers the height of one lifting point 13 on the side of the flipping tooling 1 away from the joint of the superconducting coil 2, and the crane synchronously lifts the other lifting point 13 on the side of the flipping tooling 1 close to the joint of the superconducting coil 2 at the same rate; as the heights of the two lifting points 13 change, the flipping tooling 1 gradually starts to flip axially. When the flipping tooling 1 flips to the vertically upward state, stop the actions of the two sets of hoisting equipment. At this time, the flipping tooling 1 is perpendicular to the ground, and the superconducting coil 2 is in the vertically upward state; After the turning tooling 1 is in a stable state with the vertical upward direction, the connection between the bottom lifting point 13 and the overhead crane is released. After the release, the turning tooling 1 is slowly rotated axially by 180° (which can be assisted by manpower or dragged by equipment such as a manipulator). After the rotation is completed, the bottom lifting point 13 is reconnected to the overhead crane to prepare for the subsequent turning operation; Subsequently, the two sets of lifting equipment respectively perform the lifting and lowering operations synchronously: the overhead crane slowly lifts the turning tooling 1 away from the height of the lifting point 13 on the side away from the joint of the superconducting coil 2, while the crane lowers the other lifting point 13 of the turning tooling 1 close to the joint of the superconducting coil 2 at the same rate; as the heights of the two lifting points 13 change, the turning tooling 1 gradually starts to turn in the reverse direction axially. When the turning tooling 1 turns to the horizontal upward state, the actions of the two sets of lifting equipment are stopped. At this time, the turning tooling 1 is parallel to the ground, and the superconducting coil 2 is in the horizontal upward state; When the turning tooling 1 returns to the horizontal state, the actions of the two sets of lifting equipment are stopped in time. Compared with the initial horizontal state, the superconducting coil 2 can complete an axial turn of 180°, and at the same time, the orientation of the joint of the superconducting coil 2 is turned; at the same time, the lifting hook is lifted uniformly by the lifting equipment, so that the turning tooling 1 descends parallelly until the turning tooling 1 is stably placed on the support seat.

[0039] Please continue to refer to Figure 10 , in this embodiment, S300 includes: S310, remove the limit fixture 18 and the connecting plate, and hoist the top cover 11 above the bottom cover 12 by the hoisting equipment; S320, hoist the superconducting coil 2 installed with the conformal tooling 3 out of the bottom cover 12 by the hoisting equipment.

[0040] It should be specifically noted that after the turning operation of the superconducting coil 2 is completed, the limit fixture 18, the connecting plate and the tightening bolt 4 are removed in the reverse order of the corresponding installation. After the removal work is completed, the top cover 11 is hoisted by the hoisting equipment, and then the superconducting coil 2 is hoisted to the designated storage station or the subsequent processing station by another hoisting equipment.

[0041] Finally, it should be noted that: the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
