[0031] The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0032] Such as Figure 7 and Figure 8As shown in the figure, this embodiment provides a superconducting high-speed maglev track beam structure, which includes a track beam 1, a superconducting maglev functional component 6, and a vertical wall 2 arranged on the top surface of the track beam 1; the superconducting maglev functional component 6 is connected to the vertical wall 2 through tapping screws 14 at both ends; on one side of the vertical wall 2 facing the superconducting maglev functional component 6, an internally threaded sleeve 12 arranged along the transverse direction of the bridge is embedded, and an unthreaded sleeve 13 arranged along the transverse direction of the bridge is provided inside the superconducting maglev functional component 6. Both ends of the tapping screw 14 at both ends are respectively provided with a first thread 19 and a second thread 20. The first thread 19 matches the internally threaded sleeve 12, and the second thread 20 matches the nut 15; one end of the tapping screw 14 at both ends is connected to the internally threaded sleeve 12 through the second thread 20, and the other end passes through the unthreaded sleeve 13 and is connected to the nut 15 through the first thread 19; an embedded sleeve 10 with internal threads is embedded at the bottom of the superconducting maglev functional component 6, and a elevation screw 11 for adjusting the elevation is installed in the embedded sleeve 10. The bottom end of the elevation screw 11 abuts against the top surface of the track beam 1. In this embodiment, the vertical wall 2 is used to fix the superconducting maglev functional component 6, and it is integrated with the track beam 1; by embedding the internally threaded sleeve 12 in the vertical wall 2 and embedding the unthreaded sleeve 13 in the superconducting maglev functional component 6, then connecting one end of the tapping screw 14 with threads at both ends to the internally threaded sleeve 12, and passing the other end through the unthreaded sleeve 13 and fixing it with the nut 15, and embedding the embedded sleeve 10 and installing the elevation screw 11 at the bottom of the superconducting maglev functional component 6, by rotating the tapping screw 14 and the nut 15, the transverse positioning and verticality of the superconducting maglev functional component 6 and the vertical wall 2 are precisely adjusted, and by rotating the elevation screw 11, the elevation of the superconducting maglev functional component 6 is precisely adjusted, so as to meet the precision installation requirements of the superconducting maglev functional component 6.

[0033] The superconducting high-speed maglev track beam structure of this embodiment can be used for Figures 2 - 3 the single-track shown in the figure, and can also be used for Figures 4 - 6 the double-track shown in the figure, can be used for plate girders, and can also be used for box girders, but is not limited to Figures 2 - 6 the beam cross-section form shown in the figure. In this embodiment, the superconducting maglev functional component 6 can be precisely manufactured in the factory in the manner of industrial products. The engineering quantity should be minimized. The attached concrete structure part except the electrical part is made according to the minimum requirements and does not participate in the structural load as much as possible. All the load-bearing functions are placed in the bridge structure. The track beam 1 can be designed and constructed according to the general concrete structure, but only a vertical wall 2 for fixing the superconducting maglev functional component 6 needs to be made above the bridge deck. The load-bearing function of the vertical wall 2 is a part of the bridge structure, and the electrical and attached concrete structures only rely on the vertical wall 2.

[0034] Further, a protruding bolt head 18 is provided in the middle of the double-ended tapping screw rod 14, and the protruding bolt head 18 is located between the vertical wall 2 and the superconducting magnetic levitation functional component 6. As Figure 7 and Figure 8 shown, the protruding bolt head 18 is located between the first thread 19 and the second thread 20, and the outer diameter of the protruding bolt head 18 is larger than the inner diameters of both the internal thread sleeve 12 and the non-threaded sleeve 13. When installed, the protruding bolt head 18 is located between the vertical wall 2 and the superconducting magnetic levitation functional component 6.

[0035] Further, an internal hexagonal bolt head 17 is provided on the end face of the end of the double-ended tapping screw rod 14 where the first thread 19 is provided, facilitating the rotation of the double-ended tapping screw rod 14.

[0036] Further, a lock washer 16 is also sleeved on the end of the double-ended tapping screw rod 14 where the first thread 19 is provided, and the lock washer 16 is located on the side of the nut 15 facing the non-threaded sleeve 13.

[0037] Further, the top and bottom of the superconducting magnetic levitation functional component 6 are respectively connected to the top and bottom of the vertical wall 2 through the double-ended tapping screw rod 14.

[0038] Furthermore, grooves are provided at the top and bottom of the side of the superconducting magnetic levitation functional component 6 facing away from the vertical wall 2. The non-threaded sleeve 13 penetrates through the bottom of the groove, and the nut 15 is located within the groove. As Figure 7 shown, in this embodiment, the non-threaded sleeve 13 penetrates through the bottom of the groove along the transverse bridge direction. One end of the double-ended tapping screw rod 14 is connected to the internal thread sleeve 12 within the vertical wall 2, and the other end passes through the non-threaded sleeve 13 with a diameter slightly larger than the end of the double-ended tapping screw rod 14 and extends into the groove, and is fixed within the groove through the nut 15. It can also be fixed through the nut 15 after first sleeving on the lock washer 16.

[0039] Furthermore, the embedded sleeve 10 embedded at the bottom of the superconducting magnetic levitation functional component 6 vertically penetrates through the lower side wall of the groove at the bottom of the superconducting magnetic levitation functional component 6, and the top end of the elevation screw rod 11 is located within the groove, and the bottom end abuts against the top surface of the track beam 1. As Figure 7 shown, in this embodiment, the bottom end of the elevation screw rod 11 abuts against the top surface of the track beam 1. The middle part has an external thread matching the internal thread of the embedded sleeve 10 and is threadedly connected to the embedded sleeve 10. The top end extends into the groove at the bottom of the superconducting magnetic levitation functional component 6. By turning the elevation screw rod 11 within the groove, the distance between the superconducting magnetic levitation functional component 6 and the top surface of the track beam 1 can be adjusted, achieving precise adjustment of the elevation of the superconducting magnetic levitation functional component 6.

[0040] Furthermore, a beam top embedded steel plate 9 is provided on the top surface of the track beam 1 at a position corresponding to the elevation screw 11, and the elevation screw 11 abuts against the beam top embedded steel plate 9. Figure 7 As shown, in this embodiment, a fixed beam top embedded steel plate 9 is embedded on the top surface of the track beam 1 to assist the elevation screw 11 in accurately adjusting the elevation of the superconducting magnetic suspension functional component 6 .

[0041] Furthermore, the side of the superconducting magnetic suspension functional part 6 away from the vertical wall 2 is also provided with a motor coil installation surface 7 and an 8-shaped coil installation surface 8. Figure 7 As shown, a motor coil mounting surface 7 and an 8-shaped coil mounting surface 8 are provided between the top groove and the bottom groove on the side of the superconducting magnetic levitation functional component 6 facing away from the vertical wall 2 in this embodiment, and the motor coil mounting surface 7 and the 8-shaped coil mounting surface 8 are constructed together with the superconducting magnetic levitation functional component 6 in the factory.

[0042] Furthermore, a beam top leveling layer 3 is cast on the top surface of the track beam 1, and a running surface 4 and a cross induction loop 5 are fixed on the beam top leveling layer 3. In this embodiment, the beam top leveling layer 3 is used to position and fix the cross induction loop 5 and the running surface 4 required in the low speed state.

[0043] This embodiment also provides a construction method for the superconducting high-speed magnetic suspension track beam structure, and the specific steps are as follows:

[0044] The first step is to manufacture the superconducting magnetic suspension functional part 6 with high precision in the factory. The top and bottom of the superconducting magnetic suspension functional part 6 have reserved grooves, the motor coil mounting surface 7 and the 8-shaped coil mounting surface 8, and the threaded sleeve 13 is pre-embedded. The track beam 1 is constructed and erected according to the design requirements. The track beam 1 has been integrally constructed with a vertical wall 2 and the vertical wall 2 has an internal threaded sleeve 12 pre-embedded. The top surface of the track beam 1 is pre-embedded with a beam top embedded steel plate 9. At this time, the bridge must meet certain precision requirements;

[0045] The second step is to hoist the segmented standardized block superconducting magnetic suspension functional component 6 to the corresponding position on the top surface of the track beam 1 and install the elevation screw 11 and the tapping screws 14 at both ends, so that the elevation screw 11 is connected with the embedded sleeve 10 through a thread, and the bottom end of the elevation screw 11 is against the embedded steel plate 9 on the top of the beam, and the top end of the elevation screw 11 extends into the groove at the bottom, so that the second thread 20 at one end of the tapping screw 14 is connected with the internal thread sleeve 12, and the middle of the tapping screw 14 at both ends is connected with the internal thread sleeve 12. The protruding bolt head 18 is located between the vertical wall 2 and the superconducting magnetic suspension functional part 6, and the other end of the tapping screw 14 at both ends passes through the unthreaded sleeve 13 on the superconducting magnetic suspension functional part 6 and then extends into the groove; then the elevation screw 11 is rotated in the groove to accurately adjust the elevation of the superconducting magnetic suspension functional part 6, and the transverse bridge positioning and verticality of the superconducting magnetic suspension functional part 6 and the vertical wall are accurately adjusted by rotating the tapping screws 14 at both ends in the groove, so that the superconducting magnetic suspension functional part 6 is accurately positioned;

[0046] Step 3: Fix the accurately positioned superconducting maglev functional component 6 by installing a lock washer 16 and a nut 15 on the first thread 19 of the tapping screw 14 extending into the groove on the superconducting maglev functional component 6 at both ends.

[0047] Step 4: Position and pour the deformed surface 4 and the cross induction loop 5 by pouring the leveling course 3 on the beam top.

[0048] In addition, for the influence of the post-construction creep deformation of a relatively small bridge, it can also be adjusted through the tolerance of the threadless sleeve 13, but the value is limited and it is only used when the post-construction creep deformation exceeds the prediction. If this re-adjustment method is intended to be reserved, the leveling course 3 on the beam top will not enter the range of the superconducting maglev functional component 6, and a stop block will be provided between the leveling course 3 on the beam top and the superconducting maglev functional component 6, so that the superconducting maglev functional component 6 can be replaced or its position adjusted.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
