Any one of the superconductive magnetic levitation sky street rail vehicles comprises a vehicle body 1, wherein a superconductive low-temperature container 2 is arranged on the inner bottom surface of the vehicle body 1, a high-temperature superconductor block 3 is arranged in the superconductive low-temperature container 2, and a permanent magnet track 5 is arranged under the high-temperature superconductor block 3 and positioned on the upper surface of a foundation 4. In the embodiment, the magnetic levitation track vehicle of the electromagnetic operation system designed by utilizing the principle of the like-pole repulsion of the magnets makes full use of the repulsive force generated between the magnetic field formed by the high-temperature superconductor block 3 on the vehicle and the magnetic field formed by the permanent magnet track 5, so that the vehicle body can operate in a levitation mode.
The vehicle body 1 is also connected with a telescopic wheel device 6. When the vehicle body 1 is running, the wheel device 6 is retracted into the vehicle body 1, and the air resistance during running is reduced. If the power is suddenly cut off, the wheel device 6 automatically stretches to be attached to the upper surface of the permanent magnet track 5, so that the rigid collision between the vehicle body 1 and the track is avoided.
The vehicle-mounted rechargeable battery pack 8 is mounted on the inner top surface of the vehicle body 1, and the vehicle-mounted rechargeable battery pack 8 is electrically connected with the wheel device 6.

The standby power system control module 15 is used for controlling the start and stop of the standby power system of the sky street;
the microprocessor 16 is used for receiving and processing the function information sent by other functional modules and exchanging information with the logic components.
The permanent magnet track 5 comprises an electromagnet 5-0 embedded in the foundation 4 and a track base surface 5-1. The rail base surface 5-1 is recessed with a chute 5-1-0 matched with the wheel 6-2, the sky street is provided with a standby power supply system 7, and the electromagnet 5-0 is electrically connected with the standby power supply system 7.
The backup power supply system 7 is electrically connected to the backup power supply system control module 15.
FIG. 2 is a schematic illustration of the construction of the wheel assembly during operation; as shown in fig. 2, the wheel device 6 is in a contracted state and is positioned in the chassis of the vehicle body 1 during the traveling of the magnetic levitation railway track vehicle. The wheel device 6 includes a lifting lever 6-0, a telescopic folding lever 6-1, and wheels 6-2. The top end of the lifting rod 6-0 is pivoted with the vehicle body 1 through a pivot shaft 6-3, the bottom end of the lifting rod 6-0 is connected with a wheel bracket 6-4, the wheel bracket 6-4 is connected with the hub of the wheel 6-2, and when the lifting rod 6-0 lifts, the wheel bracket 6-4 drives the wheel 6-2 to lift; one end of the telescopic folding rod 6-1 is pivoted with the vehicle body 1, the other end of the telescopic folding rod 6-1 is rotatably connected with the outer wall of the middle part of the lifting rod 6-0, and the lifting rod 6-0 can be rotated around the pivot shaft 6-3 to fold towards the inside of the vehicle body 1. When the telescopic folding rod 6-1 performs telescopic folding action, the lifting rod 6-0 rotates around the pivot shaft 6-3 so as to fold towards the inside of the vehicle body 1 or unfold towards the outside of the vehicle body 1; meanwhile, under the condition that the height of the lifting rod 6-0 is unchanged, the telescopic folding rod 6-1 rotates relatively around the joint with the lifting rod 6-0. In this embodiment, the lifting rod 6-0 and the telescopic folding rod 6-1 are electric lifting rods.
The lifting rod 6-0 is electrically connected with the lifting control module 11 and the lifting position monitoring module 12; the telescopic folding rod 6-1 is electrically connected with a telescopic folding control module 13 and a telescopic folding position monitoring module 14.
After the power failure is suddenly encountered, the power failure monitoring module 10 monitors that the permanent magnet track 5 is in a power failure state, and sends a power failure signal to the microprocessor 16; after receiving and processing the power-off signal sent by the power-on/power-off monitoring module 10, the microprocessor 16 sends a standby power system starting control signal of the sky street to the standby power system control module 15, and the standby power system control module 15 synchronously starts after receiving the relevant signal, and the standby power system 7 provides power support for the electromagnet 5-0 so as to maintain the normal operation of the vehicle body 1.
In synchronization, the microprocessor 16 receives and processes the power-off signal sent from the power-on/power-off monitoring module 10, and then sends a control signal for controlling the expansion of the wheel device 6 to the expansion/contraction folding control module 13, and sends a control signal for monitoring whether the expansion/contraction position of the wheel device 6 is in place to the expansion/contraction folding position monitoring module 14. Thereupon, after receiving the relevant signal, the telescopic folding control module 13 starts to work the telescopic folding rod 6-1 to drive the wheel device 6 to extend from the inside to the outside of the vehicle body 1 along the pivot shaft 6-3, and meanwhile, the telescopic folding position monitoring module 14, that is, the IMS-100 position detection sensor, is started. After the wheel device 6 is stretched in place, the IMS-100 position detection sensor sends a monitored in-place signal to the microprocessor 16, the microprocessor 16 processes the received information, sends a control signal for controlling the lowering of the wheel device 6 to the lifting control module 11, sends a control signal for monitoring whether the lowering position of the wheel device 6 is in place to the lifting position monitoring module 12, namely the IMS-100 position detection sensor, and simultaneously sends a control signal for stopping the stretching of the wheel device 6 to the telescopic folding control module 13. Thereupon, the wheel unit 6 stops the extending movement, and the lifting lever 6-0 starts to operate, driving the wheel unit 6 to vertically descend. After the wheel device 6 descends to the position, the IMS-100 position detection sensor sends the monitored in-position signal to the microprocessor 16, the microprocessor 16 processes the received information and sends a control signal for stopping the wheel device 6 from descending to the lifting control module 11, and then the wheel device 6 stops descending. As shown in fig. 3 and 4. At this time, the wheels 6-2 are attached to the slide grooves 5-1-0 to form rolling friction.
After the power is restored, the microprocessor 16 receives and processes the power-on signal sent from the power-on/power-off monitoring module 10, and then performs the reverse operation according to the above-mentioned intelligent execution steps. The backup power system 7 stops providing power support to the electromagnets 5-0 and the wheel unit 6 is again raised and retracted and positioned within the chassis of the vehicle body 1.
Example 2
Example 2 on the basis of example 1, a more preferred superconducting magnetic levitation skyscraper rail vehicle structure is provided, as shown in fig. 2 or fig. 3 or fig. 4. In particular, this embodiment 2 further defines that the wheel carrier 6-3 has a guard assembly 6-5 attached toward the outside of the vehicle body 1. The protection component 6-5 comprises an outer protection rod 6-5-0 with one end pivoted with the bottom of the vehicle body 1, a sliding rod 6-5-1 sliding along the outer protection rod 6-5-0 is arranged on the inner side surface of the outer protection rod 6-5-0, a connecting rod 6-5-2 is arranged on the outer side surface of the wheel 6-2, and when the wheel 6-2 is lifted in place, the bottom surface of the sliding rod 6-5-1 is attracted with the top surface of the connecting rod 6-5-2. In this embodiment, the slide bar 6-5-1 is a metal bar, and the connecting bar 6-5-2 is a magnetic metal bar with magnetic attraction effect. Preferably, the axial centerline of the slide bar 6-5-1 coincides with the axial centerline of the connecting bar 6-5-2.
When the wheel 6-2 is lifted in place, the top surface of the connecting rod 6-5-2 is attracted to the bottom surface of the sliding rod 6-5-1. During the process of shrinking and folding the wheel device 6, the connecting rod 6-5-2 adsorbs the sliding rod 6-5-1, and the sliding rod 6-5-1 slides downwards along the outer protection rod 6-5-0 under the action of adsorption force until the wheel device 6 is shrunk and folded in place. When the wheel 6-2 starts to descend, the top surface of the connecting rod 6-5-2 is separated from the bottom surface of the sliding rod 6-5-1, the connecting rod 6-5-2 descends along with the wheel 6-2, and the connecting rod 6-5-2 is fixed.
In contrast, during the extension of the wheel unit 6, the connecting rod 6-5-2 adsorbs the slide rod 6-5-1, and the slide rod 6-5-1 slides upward along the outer guard rod 6-5-0 under the adsorption force until the wheel unit 6 is extended in place.
The design of the protective assembly 6-5 prevents the wheel assembly 6 from being impacted by an unexpected object, extending the useful life of the wheel assembly 6.
Further preferably, the inner side surface of the lifting rod 6-0 is connected with a protective limiting block 6-6, so that the wheel device 6 is prevented from being contracted by a plurality of degrees due to the failure of the telescopic folding position monitoring module 14, the wheel device 6 is prevented from being damaged, and the safety of the wheel device 6 during contraction is improved.
Example 3
Example 3 on the basis of example 1 or example 2, a more preferred superconducting magnetic levitation skyscraper rail vehicle structure is provided. In particular, this embodiment 3 further defines the track base surface 5-1 with heating wires embedded therein. If snow is accumulated in the track in winter, a sky street manager turns on the heating wire heating switch, the surface temperature of the track base surface 5-1 is increased, the snow on the track is melted, the influence of the snow on the operation of the magnetic levitation track vehicle is reduced, and the personal and property safety is ensured.
Preferably, the bottom surface of the sliding groove 5-1-0 is provided with a plurality of through holes, and accumulated water in the sliding groove 5-1-0 can infiltrate into the foundation 4 through the through holes, so that slipping when the wheel 6-2 contacts with the sliding groove 5-1-0 is avoided.

The gasified nitrogen is ensured to be discharged out of the superconducting low-temperature container 2 with limited space in time, and explosion caused by large difference of internal pressure and external pressure is effectively avoided.
