Examples:

fig. 1 is a schematic structural diagram of an assembled superconducting magnetic levitation track structure according to an embodiment of the present invention, and as shown in fig. 1, the assembled superconducting magnetic levitation track structure includes two inverted-T-shaped tracks 1 and a connecting frame 2.

Fig. 2 is a cross-sectional view of an inverted T track 1 provided by an embodiment of the present invention, as shown in fig. 2, two inverted T tracks 1 are laterally spaced and symmetrically arranged, each inverted T track 1 is provided with a first wire slot 11 and a second wire slot 12 which are mutually communicated toward one side of the corresponding inverted T track 1, the first wire slot 11 is located outside the second wire slot 12, a suspension guide coil 13 is inserted into the first wire slot 11, a traction coil 14 is inserted into the second wire slot 12, a plurality of adjusting holes 15 which are arranged at intervals are provided on each inverted T track 1, each adjusting hole 15 is communicated with the first wire slot 11 or the second wire slot 12, a first anchoring bolt 16 is inserted into each adjusting hole 15, the suspension guide coil 13 or the traction coil 14 is fixed at one end of the corresponding first anchoring bolt 16, and the other end of the first anchoring bolt 16 is configured to be inserted into the corresponding adjusting hole 15 and moved to be adjusted in place, and then anchored in the corresponding adjusting hole 15 after being filled with an anchoring agent.

The connecting frame 2 and each inverted T-shaped track 1 are prefabricated structural members, two wheel running surfaces 21 which are arranged at intervals are formed at the top of the connecting frame 2, the connecting frame 2 is positioned between the two inverted T-shaped tracks 1, and two ends of the connecting frame 2 are respectively connected with the corresponding inverted T-shaped tracks 1 through post-pouring belts 22.

When the assembled superconducting magnetic levitation track structure provided by the embodiment of the invention is used for construction, firstly, the inverted T-shaped track 1 and the connecting frame 2 are prefabricated, so that the concrete pouring amount of a construction site is reduced, and the construction efficiency is improved. Then, according to the design requirement, two inverted T-shaped tracks 1 are paved at intervals, a connecting frame 2 is paved between the two inverted T-shaped tracks 1, and a post-pouring belt 22 is poured between two ends of the connecting frame 2 and the corresponding inverted T-shaped tracks 1, so that the left inverted T-shaped track 1 and the right inverted T-shaped track 1 form a whole, and the track precision is better in the use process.

Then, the levitation guide coil 13 or the traction coil 14 is fixed to one end of the corresponding first anchor bolt 16, thereby achieving connection of the coil and the first anchor bolt 16. Finally, the other end of the first anchor bolt 16 is inserted into the corresponding adjusting hole 15 and is moved to be adjusted in place, and then is filled with an anchoring agent and then anchored in the corresponding adjusting hole 15. Because the inverted T-shaped track 1 can form certain errors in the prefabrication and installation processes, the positions of the first anchor bolts 16 and the corresponding coils are accurately adjusted by adjusting the transverse or longitudinal movement of the first anchor bolts 16 in the adjusting holes 15 with larger sizes, and the positions are filled and fixed through the anchoring agent after the adjustment is finished, so that the accurate fixation of the suspension guide coils 13 or the traction coils 14 is finally and rapidly completed, and the construction efficiency is further ensured.

That is, according to the assembled superconducting magnetic levitation track structure provided by the embodiment of the invention, concrete pouring on a construction site can be reduced, the integrity and the precision of the two inverted T-shaped tracks 1 are ensured, and accurate fixing of the levitation guide coil 13 or the traction coil 14 can be rapidly completed, so that the construction efficiency is improved.

The side edge of the inverted T-shaped track 1 forms a guide wheel support surface 110 of the train, which is located above the first wire groove 11 and the second wire groove 12. In addition, the prefabricated structures such as the connecting frame 2, the inverted T-shaped track 1 and the like can adopt nonmagnetic ribs or nonmagnetic high-performance concrete.

It is easy to understand that the levitation guiding coil 13 generates magnetic force to levitation and guide the train, and the traction coil 14 generates magnetic force to drive the train.

For example, the number of adjustment holes 15 may be 4, with the middle 2 adjustment holes 15 for securing the traction coil 14 and the other 2 coils for securing the levitation guide coil 13.

Illustratively, the anchoring agent may be a sulfur-anchored mortar, capable of rapid setting and filling.

That is, by inserting the cable into the third wire groove 17, power supply to the levitation guide coil 13 and the traction coil 14 can be achieved.

Fig. 3 is an assembly schematic diagram of a first anchor bolt provided in an embodiment of the present invention, as shown in fig. 3, one end of each first anchor bolt 16 is sleeved with a first positioning nut 161 and a first fastening nut 162, a suspension guiding coil 13 or a traction coil 14 is clamped between the first positioning nut 161 and the first fastening nut 162, and clamping of the coil can be conveniently realized through the first positioning nut 161 and the first fastening nut 162, so that fixation of the coil on the first anchor bolt 16 is realized.

Referring again to fig. 1, the fabricated superconducting magnetic levitation track structure further comprises a lower foundation 3 and two adjusting layers 4 arranged at intervals, wherein each adjusting layer 4 is located between the lower foundation 3 and the inverted-T-shaped track 1 and is a cast-in-place concrete structure.

In the above embodiment, the adjustment layer 4 may be cast in place after the pouring of the lower foundation 3 is completed and after the inverted T-shaped rail 1 is positioned to a proper height according to the design requirement, so as to smooth out the construction error of the lower foundation 3.

Illustratively, the lower foundation 3 is pre-embedded with reserved connection bars, so that reliable connection of the lower foundation 3 and the adjustment layer 4 is realized by the connection bars when the adjustment layer 4 is poured.

Similarly, when the inverted T-shaped tracks 1 do not need to be subjected to position adjustment, gate-shaped steel bars are inserted into the bottoms of the inverted T-shaped tracks 1, so that the inverted T-shaped tracks 1 are fixed, and the inverted T-shaped tracks 1 are fixed through the gate-shaped steel bars.

In one implementation manner of the present invention, fig. 4 is an assembly schematic diagram of a second anchor bolt provided in an embodiment of the present invention, as shown in fig. 4, a plurality of second anchor bolts 41 arranged at intervals are inserted into each adjustment layer 4, one end of each second anchor bolt 41 is inserted into the adjustment layer 4, the other end of each second anchor bolt 41 penetrates through the bottom of the inverted T-shaped track 1, and the other end of each second anchor bolt 41 is sleeved with a second anchor nut 411 to fix the bottom of the inverted T-shaped track 1 on the adjustment layer 4.

In the above embodiment, the inverted T-shaped rail 1 can be fixed to the adjustment layer 4 by embedding the second anchor bolt 41 and engaging the second anchor nut 411, so that the position accuracy of the inverted T-shaped rail 1 is prevented from being affected by the relative displacement of the two.

When the inverted T-shaped rails 1 need to be subjected to position adjustment, through holes 18 are formed in the bottoms of the inverted T-shaped rails 1, the diameter of each through hole 18 is larger than that of each second anchor bolt 41, a distance adjusting ring 19 is detachably inserted into a clearance space between each through hole 18 and each second anchor bolt 41 so as to transversely adjust the positions of the inverted T-shaped rails 1, and the second anchor nuts 411 abut against the tops of the distance adjusting rings 19.

Fig. 5 is a schematic structural view of a first distance adjusting ring according to an embodiment of the present invention, and fig. 6 is a schematic structural view of a second distance adjusting ring according to an embodiment of the present invention, and in combination with fig. 5 to 6, when the inverted T track 1 is installed, the clearance space between the through hole 18 and the second anchor bolt 41 is filled by the distance adjusting ring 19 with the inner hole being centered, and the second anchor bolt 41 is located at the center of the through hole 18.

Illustratively, when the track structure position needs to be adjusted during operation:

When the lower foundation 3 and the adjusting layer 4 drive the inverted T-shaped track 1 to move transversely to the left, the second anchoring nut 411 is unscrewed, the distance adjusting ring 19 with the inner hole being right centered is taken out and the inverted T-shaped track 1 is moved to the right to a proper position, at the moment, the second anchoring bolt 41 is eccentric relative to the through hole 18, and finally, the second anchoring nut 411 is screwed by inserting the distance adjusting ring 19 corresponding to the eccentric inner hole in the through hole 18.

Similarly, when the lower foundation 3 and the adjusting layer 4 drive the inverted T-shaped track 1 to move transversely to the right or longitudinally, the corresponding inner hole eccentric distance adjusting ring 19 can be inserted in the mode, so that the transverse or longitudinal position of the inverted T-shaped track 1 is adjusted. That is, the position of the inverted-T-shaped track 1 can be reasonably adjusted through the second anchor bolts 41 and the distance adjusting ring 19, so that the condition that the T-shaped track accidentally moves in the operation process is met, and the application range of the structure is enlarged.

Referring again to fig. 4, the bottom of the second anchor bolt 41 abuts against the lower foundation 3, and a second positioning nut 412 is sleeved on the second anchor bolt 41, and the second positioning nut 412 is located below the bottom of the inverted-T track 1 so as to clamp the bottom of the inverted-T track 1.

It is easy to understand that the bottom of the second anchor bolt 41 is propped against the lower foundation 3, and the support of the inverted-T-shaped track 1 can be automatically realized through the support of the second anchor bolt 41 and the clamping of the second positioning nut 412 and the second anchor nut 411 in the process of pouring the adjusting layer 4, so that the inverted-T-shaped track 1 is prevented from being hoisted by using hoisting equipment when the adjusting layer 4 is poured.

Illustratively, a second positioning nut 412 is inserted in the adjustment layer 4, which can simultaneously support the adjustment ring 19, avoiding the adjustment ring 19 from moving downward during pouring of the adjustment layer 4.

In addition, the other end of the second anchor bolt 41 is sleeved with a gasket, and the gasket is clamped between the second anchor nut 411 and the bottom of the inverted-T track 1, so that the clamping area is increased, and the second anchor nut 411 is prevented from being embedded into the inverted-T track 1.

Similarly, a spacer is also interposed between the second positioning nut 412 and the inverted-T track 1.

And S105, inserting the other end of the first anchoring bolt 16 into the corresponding adjusting hole 15, moving and adjusting the other end into position, filling the other end with an anchoring agent, and then anchoring the other end in the corresponding adjusting hole 15.
