[0041] The coil auxiliary positioning device 100 according to the embodiments of the present application is described in detail below in conjunction with the annexes.

[0042] Referring to Figures 1-13As shown, the coil auxiliary positioning device 100 is used for the assembly of the coil 200 and the line box 300 in the tokamak device, the line box 300 has a line slot 301, the coil 200 is installed in the line slot 301 through the coil auxiliary positioning device 100, the coil auxiliary positioning device 100 includes an assembly hanger 10, the assembly hanger 10 includes a connecting assembly 1 and a guide limiting assembly 2, the connecting assembly 1 includes a hanging piece 11 and a mounting piece 12 connected with each other, the hanging piece 11 is detachably hung on the outer edge of the line slot 301, the mounting piece 12 is attached to the inner side wall of one side of the line slot 301, the guide limiting assembly 2 includes a guide piece 21, a connecting piece 22 and a limiting piece 23, the connecting piece 22 is installed on the mounting piece 12, and the guide piece 21 and the limiting piece 23 are connected with the mounting piece 12. In the depth direction of the line slot 301, the guide piece 21 is adapted to guide the coil 200. In the width direction of the line slot 301, the size of the limiting piece 23 is adjustable, the size error of the coil 200 at the contact position with the guide piece 21 is W1, the basic size of the limiting piece 23 is W2, and the actual size of the limiting piece 23 after adjustment is W2-W1, so that after the coil 200 is installed in the line slot 301, the coil 200 is pressed against the guide piece 21, and the limiting piece 23 is in abutment with the mounting piece 12.

[0043] Specifically, the tokamak device is a toroidal vessel for realizing controllable nuclear fusion by magnetic confinement, which is arranged with a toroidal field coil along the circumferential direction of the toroidal vessel, the toroidal field coil includes the coil 200 and the line box 300, the coil 200 can be a huge D-shaped coil winding (the size can be meter level), the line box 300 can be an inner leg segment coil box corresponding to the straight edge segment of the D-shaped coil winding, the coil 200 needs to be installed in the line slot 301 of the line box 300, and the assembly precision of the coil 200 and the line box 300 directly determines the precision of the magnetic field, and further affects the stable confinement of the plasma.

[0044] When the coil 200 and the line box 300 are assembled, the assembly hanger 10 of the coil auxiliary positioning device 100 can be hung at the line slot 301 of the line box 300 to provide guidance for the assembly of the coil 200, and at the same time, the size of the limiting piece 23 of the assembly hanger 10 can be adjusted according to the size error of the coil 200, so that when the coil 200 has a size error, the assembly precision of the coil 200 and the line box 300 can still be ensured. After the coil 200 and the line box 300 are assembled, the assembly hanger 10 can be detached from the line box 300, so as to avoid that the assembly hanger 10 affects the subsequent assembly of the tokamak device.

[0045] The connecting assembly 1 of the assembly hanger 10 comprises a hanging piece 11 and a mounting piece 12 connected together, and the hanging piece 11 and the mounting piece 12 can be connected together integrally or through fasteners. The hanging piece 11 and the mounting piece 12 can form a generally L-shaped bracket structure. The hanging piece 11 is detachably hung on the outer edge of the wire slot 301, and the mounting piece 12 is attached to the inner side wall on one side of the wire slot 301. The outer edge and the inner side wall of the wire slot 301 can support the hanging piece 11 and the mounting piece 12 respectively, so as to ensure the stability and reliability of the connection between the connecting assembly 1 and the junction box 300. The guide and limiting assembly 2 of the assembly hanger 10 comprises a guide piece 21, a connecting piece 22 and a limiting piece 23. The connecting piece 22 is installed on the mounting piece 12, and at least part of the limiting piece 23 is located between the mounting piece 12 and the connecting piece 22. At least part of the guide piece 21 is located on the side of the mounting piece 12 away from the connecting piece 22.

[0046] In the depth direction of the wire slot 301, that is, the up-down direction in the Figures 8-13 The guide piece 21 is adapted to guide the coil 200, so that when the coil 200 is installed into the wire slot 301 of the junction box 300, the coil 200 can stably and reliably enter the wire slot 301, and the risk of deflection of the coil 200 relative to the wire slot 301 is reduced.

[0047] In the width direction of the wire slot 301, that is, the left-right direction in the Figures 8-13 The limiting piece 23 has an adjustable size. The size error of the coil 200 at the position of contact with the guide piece 21 is W1, the basic size of the limiting piece 23 is W2, and the actual size of the limiting piece 23 after adjustment is W2-W1. After the coil 200 is installed into the wire slot 301, the coil 200 presses against the guide piece 21, and the limiting piece 23 abuts against the mounting piece 12.

[0048] For example, the size error of the coil 200 at the position of contact with the guide piece 21 is 0 mm (no error), and the basic size of the limiting piece 23 is 10 mm. In this case, after the coil 200 is installed into the wire slot 301, the coil 200 presses against the guide piece 21 of the guide and limiting assembly 2 in the left-right direction, so that the limiting piece 23 of the guide and limiting assembly 2 abuts against the mounting piece 12. At the same time, the mounting piece 12 also abuts against the inner side wall of the wire slot 301. That is, in the left-right direction, the coil 200 and the inner side wall of the wire slot 301 are sandwiched by the guide piece 21, the connecting piece 22, the limiting piece 23 and the mounting piece 12. The gap between the coil 200 and the inner side wall of the wire slot 301 is equal to the size of the guide piece 21, the connecting piece 22, the limiting piece 23 and the mounting piece 12 in the left-right direction.

[0049] For another example, the size error of the coil 200 corresponding to the contact position of the guide 21 is +4mm (the coil 200 protrudes 4mm to the axial outside), the basic size of the limiting member 23 is 10mm, and the actual size of the limiting member 23 after adjustment is 10mm-4mm=6mm. In this case, after the coil 200 is installed into the wire slot 301, the gap between the coil 200 and the inner side wall of the wire slot 301 in the left-right direction is equal to the size of the whole of the guide 21, the connecting member 22, the limiting member 23 and the mounting member 12 in the left-right direction, so as to improve the installation precision of the coil 200 when the coil 200 has a size error.

[0050] For another example, the size error of the coil 200 corresponding to the contact position of the guide 21 is -3mm (the coil 200 is recessed 3mm to the axial inside), the basic size of the limiting member 23 is 10mm, and the actual size of the limiting member 23 after adjustment is 10mm-(-3)mm=13mm. In this case, after the coil 200 is installed into the wire slot 301, the gap between the coil 200 and the inner side wall of the wire slot 301 in the left-right direction is equal to the size of the whole of the guide 21, the connecting member 22, the limiting member 23 and the mounting member 12 in the left-right direction, so as to improve the installation precision of the coil 200 when the coil 200 has a size error.

[0051] It can be understood that, before the coil 200 is installed into the wire slot 301 of the wire box 300, the size of the coil 200 can be accurately measured, for example, by a three-coordinate measuring machine, to determine the size error W1 of the coil 200 corresponding to the contact position of the guide 21, and then the size of the limiting member 23 is adjusted according to W1.

[0052] It should be noted that the size adjustment of the limiting member 23 can be realized by replacing the limiting member 23 of different specifications, or by the extension and contraction of the limiting member 23, for example, the limiting member 23 is an electric or hydraulic telescopic rod.

[0053] The coil auxiliary positioning device 100 according to the embodiments of the present application can adjust the size of the limiting member 23 according to the size error of the coil 200 corresponding to the contact position of the guide 21, so as to improve the assembly precision of the coil 200 and the wire box 300 when the coil 200 has a size error, thereby facilitating the improvement of the magnetic field precision of the tokamak device and ensuring the stable confinement of the plasma.

[0054] In some embodiments of the present application, the connecting member 22 and the mounting member 12 are detachably connected, and / or the connecting member 22 and the limiting member 23 are detachably connected.

[0055] In some embodiments, referring to Figure 7As shown, the connecting piece 22 is detachably connected with the mounting piece 12, the connecting piece 22 and the mounting piece 12 can be detachably connected through a fastener such as a snap spring 25, or can be detachably connected through a buckle structure, the limiting piece 23 can be integrally connected with the connecting piece 22, when it is necessary to adjust the size of the limiting piece 23, different connecting pieces 22 can be detached and replaced on the mounting piece 12, each connecting piece 22 corresponds to the limiting piece 23 of different sizes, thereby realizing the adjustment of the size of the limiting piece 23.

[0056] In other embodiments, the connecting piece 22 is detachably connected with the limiting piece 23, the connecting piece 22 and the limiting piece 23 can be detachably connected through plug-in, threaded connection and the like, when it is necessary to adjust the size of the limiting piece 23, different sizes of the limiting piece 23 can be detached and replaced on the connecting piece 22, thereby realizing the adjustment of the size of the limiting piece 23.

[0057] In other embodiments, the connecting piece 22 is detachably connected with the mounting piece 12, and the connecting piece 22 is detachably connected with the limiting piece 23, so as to facilitate the adjustment of the size of the limiting piece 23, and also facilitate the maintenance and replacement of the connecting piece 22.

[0058] In some embodiments of the present application, with reference to Figures 7-13 As shown, the guiding and limiting assembly 2 further comprises an elastic piece 24, the connecting piece 22 is movably connected with the mounting piece 12 in the width direction of the wire slot 301, the elastic piece 24 is arranged between the connecting piece 22 and the mounting piece 12, and the elastic piece 24 is used to exert a force on the connecting piece 22 away from the mounting piece 12, so as to separate the limiting piece 23 from the mounting piece 12 before the coil 200 is installed into the wire slot 301.

[0059] Specifically, in the left-right direction, the connecting piece 22 is movably connected with the mounting piece 12, the elastic piece 24 is arranged between the connecting piece 22 and the mounting piece 12, and the elastic piece 24 can always be in a compressed state, and the elastic piece 24 exerts a force on the connecting piece 22 away from the mounting piece 12.

[0060] Before the coil 200 is installed into the wire slot 301, the elastic piece 24 separates the limiting piece 23 from the mounting piece 12, that is, the guide piece 21, the connecting piece 22 and the limiting piece 23 are located away from the mounting piece 12, thereby facilitating the guiding function of the guide piece 21 when the coil 200 is installed into the wire slot 301.

[0061] It can be understood that the width of the lower end of the coil 200 is smaller than the width of the upper end of the coil 200, when the coil 200 is installed from top to bottom to the wire slot 301, the limiting piece 23 can be separated from the mounting piece 12 due to the action of the elastic piece 24, the guide piece 21 is in contact with the axial end surface of the lower end of the coil 200 to provide guidance for the falling of the coil 200, and the risk of shaking and deflection of the coil 200 is reduced. With the falling of the coil 200, the width of the coil 200 gradually increases, so that the coil 200 can move the connecting piece 22 to the mounting piece 12 direction by the pushing of the guide piece 21, and the compression amount of the spring becomes larger. When the coil 200 is installed in place, the axial end surface of the upper end of the coil 200 abuts against the guide piece 21, and the limiting piece 23 abuts against the mounting piece 12.

[0062] It should be noted that the elastic piece 24 can be a spiral spring or a rubber spring.

[0063] In some embodiments of the present application, as shown in Figure 7 、 Figure 12 and Figure 13 , the mounting piece 12 has a mounting guide rod 121, and the connecting piece 22 is provided with a connecting hole 221, and in the width direction of the wire slot 301, the connecting hole 221 is movably sleeved on the mounting guide rod 121.

[0064] Specifically, the mounting guide rod 121 extends in the width direction of the wire slot 301, and in the extension direction of the mounting guide rod 121, the connecting hole 221 on the connecting piece 22 is movably sleeved on the mounting guide rod 121, that is, the connecting hole 221 and the mounting guide rod 121 are guided and matched in the left-right direction, and the structure of the mounting piece 12 and the connecting piece 22 is simple, and the manufacturing and assembly are convenient.

[0065] As shown in Figure 7 , the number of the mounting guide rod 121 and the connecting hole 221 is multiple and one-to-one, so as to improve the stability and reliability of the movement of the connecting piece 22 relative to the mounting piece 12.

[0066] In some embodiments of the present application (not shown in the figure), the mounting piece 12 has a slide rail extending in the width direction of the wire slot 301, and the connecting piece 22 is slidably matched with the slide rail in the width direction of the wire slot 301,

[0067] In some embodiments of the present application, as shown in Figure 12 and Figure 13 , the elastic piece 24 is sleeved on the mounting guide rod 121, and the mounting guide rod 121 can avoid the elastic piece 24 from loosening and falling, so as to improve the stability and reliability of the elastic piece 24.

[0068] In some embodiments of the present application, as shown in Figure 6 and Figure 7As shown, the connecting member 22 is provided with a connecting guide rod 222, and the guide member 21 is configured as a roller 21a which is rotatably sleeved on the connecting guide rod 222.

[0069] Specifically, the connecting guide rod 222 extends along the length direction of the wire slot 301, the roller 21a is rotatably sleeved on the connecting guide rod 222, the roller 21a can rotate around the axis of the connecting guide rod 222, when the coil 200 is mounted to the wire slot 301, the axial end face of the coil 200 can be in contact with the roller 21a, the roller 21a provides guidance to the coil 200 by rotating, and reduces the assembly resistance of the coil 200, the structure of the connecting member 22 and the guide member 21 is simple, and the manufacturing and assembly are convenient.

[0070] Referring to Figure 6 and Figure 7 As shown, the number of the connecting guide rod 222 and the roller 21a is multiple and one-to-one corresponding, when the coil 200 is assembled, the guide limiting assembly 2 can provide support and guidance to the coil 200 through the multiple rollers 21a, so as to facilitate the assembly of the coil 200.

[0071] Referring to Figure 6 and Figure 7 As shown, the mounting guide rod 121 and the connecting guide rod 222 are both provided with a snap spring 25, the snap spring 25 on the mounting guide rod 121 can limit the connecting member 22 thereon, so as to avoid the connecting member 22 from coming out of the mounting guide rod 121, and the snap spring 25 on the connecting guide rod 222 can limit the roller 21a thereon, so as to avoid the roller 21a from coming out of the connecting guide rod 222.

[0072] In some embodiments of the present application, referring to

[0073] In some embodiments of the present application, referring to Figure 5 and Figure 9 As shown, the connecting assembly 1 further comprises a handle 13, the handle 13 is connected to the side of the hanging member 11 away from the outer edge of the wire slot 301, the handle 13 can be a U-shaped plate, the handle 13 is located on the side of the hanging member 11 away from the outer edge of the wire slot 301, both ends of the handle 13 are connected to the hanging member 11, and the middle part of the handle 13 is separated from the hanging member 11, the hanging member 11 can be hung on the outer edge of the wire slot 301 through the handle 13, and the hanging member 11 can be taken out from the outer edge of the wire slot 301 through the handle 13, the handle 13 can facilitate the operator or equipment to take and place the mounting rack 10, so as to facilitate the use of the coil auxiliary positioning device 100.

[0074] In some embodiments of the present application, referring to Figure 9As shown, the mounting component 11 includes a hanging plate 111 and a hook plate 112 connected at an angle. The hanging plate 111 can overlap the upper surface of the outer edge of the wire trough 301 (the edge of the slot between the inner and outer side walls of the wire trough 301). The hook plate 112 is opposite to the mounting component 12 and fits against the outer side wall of the wire trough 301. The hook plate 112 and the mounting component 12 can be positioned and cooperate with the side wall of the wire trough 301 to improve the positional accuracy and stability of the connecting component 1 hanging on the wire box 300.

[0075] In some embodiments of the present invention, reference is made to... Figure 1 , Figure 4 and Figure 8 As shown, there are multiple mounting brackets 10. At least one mounting bracket 10 can be detachably installed on both sides of the wire groove 301 in the width direction of the wire groove 301.

[0076] Specifically, the width direction of the wire groove 301 is parallel to the axial direction of the coil 200. Before the coil 200 is installed into the wire groove 301, at least one assembly bracket 10 can be installed on both sides of the wire groove 301 in the width direction. During the installation of the coil 200 into the wire groove 301, the assembly brackets 10 on both sides of the wire groove 301 in the width direction can guide and position the coil 200. When the coil 200 has an axial dimensional deviation, the dimensional adjustment of the limiting member 23 is used to compensate for the dimensional deviation of the coil 200, thereby ensuring that the coil 200 can be installed centered in the wire groove 301 and improving the assembly accuracy of the coil 200. After the coil 200 is installed in place, the assembly bracket 10 can be pulled out and removed from the wire groove 301 to avoid the assembly bracket 10 affecting subsequent assembly.

[0077] In some embodiments of the present invention, reference is made to... Figure 1 and Figure 8 As shown, in the width direction of the wire groove 301, the mounting brackets 10 on both sides of the wire groove 301 face each other. During the installation of the coil 200 into the wire groove 301, the mounting brackets 10 on both sides of the wire groove 301 can provide stable and reliable guidance and positioning for the coil 200 on both axial sides, reducing the risk of the coil 200 being misaligned during assembly, thereby improving the stability of the assembly of the coil 200 and the wire groove 301 and reducing the assembly difficulty.

[0078] In other embodiments of the present invention (not shown in the figures), the mounting brackets 10 on both sides of the wire groove 301 are staggered in the width direction of the wire groove 301 to reduce the number of mounting brackets 10 used and improve the assembly efficiency of the coil 200 and the wire groove 301.

[0079] In some embodiments of the present invention, reference is made to... Figure 2 and Figure 10As shown, the coil auxiliary positioning device 100 further comprises a vertical limiting block 20 installed on the bottom wall of the wire slot 301, which is used to support the coil 200 in the depth direction of the wire slot 301, and the size of the vertical limiting block 20 is adjustable.

[0080] Specifically, in the depth direction of the wire slot 301, i.e. Figure 10 the size of the vertical limiting block 20 is adjustable, the size error corresponding to the contact position of the coil 200 and the vertical limiting block 20 is H1, the basic size of the vertical limiting block 20 is H2, and the actual size of the vertical limiting block 20 after adjustment is H2-H1. After the coil 200 is installed into the wire slot 301, the size of the coil 200 in the depth direction of the wire slot 301 is compensated by adjusting the size of the vertical limiting block 20, and the position accuracy of the coil 200 installation is improved.

[0081] For example, the size error corresponding to the contact position of the coil 200 and the vertical limiting block 20 is 0 mm (no error), the basic size of the vertical limiting block 20 is 10 mm, and the vertical limiting block 20 does not need to be adjusted in size. In this case, after the coil 200 is installed into the wire slot 301, the coil 200 is pressed against the vertical limiting block 20 in the up-down direction, that is, the vertical limiting block 20 is sandwiched between the coil 200 and the bottom wall of the wire slot 301 in the up-down direction, and the gap between the coil 200 and the bottom wall of the wire slot 301 is equal to the size of the vertical limiting block 20.

[0082] For another example, the size error corresponding to the contact position of the coil 200 and the vertical limiting block 20 is +2 mm (the coil 200 protrudes 2 mm radially outward), the basic size of the vertical limiting block 20 is 10 mm, and the actual size of the vertical limiting block 20 after adjustment is 10 mm-2 mm=8 mm. In this case, after the coil 200 is installed into the wire slot 301, the gap between the coil 200 and the bottom wall of the wire slot 301 in the up-down direction is equal to the actual size of the vertical limiting block 20, so as to improve the installation accuracy of the coil 200 when the coil 200 has a size error.

[0083] For another example, the size error corresponding to the contact position of the coil 200 and the vertical limiting block 20 is -1 mm (the coil 200 is recessed 1 mm radially inward), the basic size of the vertical limiting block 20 is 10 mm, and the actual size of the vertical limiting block 20 after adjustment is 10 mm-(-1) mm=11 mm. In this case, after the coil 200 is installed into the wire slot 301, the gap between the coil 200 and the bottom wall of the wire slot 301 in the up-down direction is equal to the actual size of the vertical limiting block 20, so as to improve the installation accuracy of the coil 200 when the coil 200 has a size error.

[0084] It can be understood that before the coil 200 is installed into the wire slot 301 of the wire box 300, the size of the coil 200 can be accurately measured, for example, by a coordinate measuring machine, to determine the size error H1 corresponding to the position where the coil 200 contacts the vertical limiting block 20, and then the actual size of the vertical limiting block 20 is adjusted according to H1.

[0085] It should be noted that the size adjustment of the vertical limiting block 20 can be achieved by replacing vertical limiting blocks 20 of different specifications. In addition, the vertical limiting block 20 can also include a plurality of shims, and the corresponding number or thickness of shims can be selected and welded to obtain vertical limiting blocks 20 of different sizes. After the coil 200 is installed into the wire box 300, the vertical limiting block 20 does not need to be removed and needs to be retained in the wire slot 301 to support the coil 200.
