Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic levitation type traveling device, and more particularly to a magnetic levitation type traveling device which can realize stable levitation traveling and is easy to handle.

[0002]

2. Description of the Related Art As is well known, various types of magnetic levitation traveling devices have been considered. Recently, Japanese Patent Laid-Open No. 1-1
As disclosed in Japanese Patent No. 33840, there has been proposed one in which a traveling vehicle is magnetically levitated by utilizing a high temperature superconducting technique.

In the one disclosed in Japanese Patent Laid-Open No. 1-133840, a traveling vehicle is equipped with a material (hereinafter, referred to as a high temperature superconductor) which is in a superconducting state at a temperature higher than the liquid nitrogen temperature level. The traveling vehicle is levitated by utilizing the Meissner effect of this high-temperature superconductor. That is, the traveling vehicle is levitated by the magnetic repulsive force generated between the high-temperature superconductor mounted on the traveling vehicle and the permanent magnet provided on the track side. Then, a coil array is provided on the track side, a high temperature superconductor is captured between magnetic poles generated by the excitation of the coil array, and excitation of the coil is sequentially switched to move the capture position to give a traveling force.

However, the magnetic levitation type traveling device in which the high temperature superconductor is mounted on the traveling vehicle as described above has the following problems. That is, in the method of levitating a traveling vehicle by using the Meissner effect, permanent magnets having different polarities are arranged at the central portion and the left and right ends along the path of the track, and the magnetic field lines of these permanent magnets make up the magnetic field. Since the traveling vehicle is levitated in the valley of the potential, a large guiding force cannot be obtained, and there is a problem that the traveling vehicle is easily deviated from the track when an external force such as a centrifugal force is applied to the traveling vehicle. Also,
When the high-temperature superconductor is larger than the width of the magnetic field for levitation given from the orbital side, it is difficult to realize a stable levitation state because a magnetic guiding force cannot be obtained. In addition, when the center of gravity of the traveling vehicle is deviated due to a load on the traveling vehicle or the like, it is difficult to maintain a predetermined floating posture. Further, it is difficult to start from an arbitrary position on the orbit, and the starting position is specified, so there is a problem that the degree of freedom of application is lacking.

[0005]

As described above, the conventional magnetic levitation type traveling device which uses the high temperature superconductor to obtain the levitation force and the traveling force is not only lacking in running stability. , There was a problem that lacked flexibility of application.

Therefore, the present invention is directed to a magnetic levitation type traveling device which utilizes a high-temperature superconductor and which can always obtain a stable levitation state, is highly stable and applicable, and is easy to handle. I am trying.

[0007]

In order to achieve the above object, a magnetic levitation traveling apparatus according to the present invention provides a magnetic field in which magnetic flux is distributed along a route in a pattern defined in a direction orthogonal to the route. An orbit with a magnetic field generating means to form,
A traveling vehicle that is arranged to travel freely on this track, and a magnetic field that holds a magnetic field in which magnetic flux is distributed in a pattern determined by the pinning effect and that is mounted on the traveling vehicle and that is formed by the magnetic field generating means. A high-temperature superconducting element that gives a levitation force and a guiding force to the traveling vehicle by a magnetic force generated between the traveling vehicle and the high-temperature superconducting element, which is provided close to the track, and is non-contact with the traveling vehicle by the magnetic force generated between the high-temperature superconducting element. Propulsion means to give propulsion,
The high temperature superconducting element comprises pinning magnetic field generating means for generating a magnetic field for pinning a magnetic flux, and a pinning station connected to the track. In the pinning station, the magnetic flux density in the high temperature superconducting element when the traveling vehicle is positioned at the pinning location is such that the traveling vehicle is in the track state under the condition that the high temperature superconducting element is in the normal conducting state. The magnetic field generated by the pinned magnetic field generating means is applied to the high temperature superconducting element in such a manner that the magnetic field becomes smaller than the magnetic flux density at the same place in the high temperature superconducting element when positioned above.

[0008]

[Operation] A high-temperature superconducting element is mounted on the traveling vehicle,
This high temperature superconducting element holds a magnetic field in which magnetic flux is distributed in a pattern defined by the pinning effect. Therefore,
If a magnetic field with a uniform magnetic flux distribution in the traveling direction of the traveling vehicle is formed on the track, it is possible to maintain a stable floating state.
When the propulsion means is operated while the traveling vehicle is levitating, the propulsive force can be applied to the traveling vehicle and the traveling vehicle can travel at an arbitrary speed.

Further, a pinning station is provided so as to be connected to the track so that the magnetic flux can be pinned to the high temperature superconducting element using the pinning magnetic field generating means. In this case, since the magnetic field is applied to the high temperature superconducting element so that the magnetic flux density of the above relation is obtained by the pinning magnetic field generating means, when the traveling vehicle is moved on the track after the high temperature superconducting element has transitioned to the superconducting state. On the track, the traveling vehicle stably floats at a flying height at which a magnetic flux density approximately the same as the magnetic flux density in the high temperature superconducting element is obtained. As a result, the traveling vehicle can be easily levitated on the track. Further, since the levitation force and the guide force obtained by the pinning effect are larger than the force obtained by the Meissner effect, even if an external force is applied to the traveling vehicle, the levitation force and the guide force are not deviated from the track.

On the other hand, a pinning station 40 is provided at the end of the track 12 so as to be continuous with the end of the track 12. The pinning station 40 is for pinning a magnetic flux to the high-temperature superconductor 23, and is a pinning magnetic field generator 41 formed of a permanent magnet and an orbit provided on the upper surface of the pinning magnetic field generator 41. The spacer 42 is made of a non-magnetic material and maintains the same height level as that of the magnet 12, and the magnet support plate 43 and the pedestal 44 are interposed between the pinned magnetic field generator 41 and the base 11.

The pinning magnetic field generator 41 is composed of the magnet support plate 4
A plurality of permanent magnets 45, which are made of the same material as the permanent magnet 14 and have a small thickness, are arranged on the upper surface of 3 as shown in FIG. 5, and are fixed to the magnet support plate 43 with an adhesive. ing. The permanent magnets 45 are arranged in the same manner as in the track 12, but are arranged such that the upper surface of the central portion is the S pole and the outer upper surface surrounding the central pole is the N pole. With this arrangement, a gradient of the magnetic potential is generated at the portions indicated by the boundaries B and B ′ between the end of the track 12 and the pinning magnetic field generator 41. The gradient of this magnetic potential is
When the traveling vehicle 13 on the track 12 approaches the portion indicated by B, a force for returning the traveling vehicle 13 to the side of the track 12 is applied, whereby the traveling vehicle 13 is erroneously pinned to the station 4
Avoid entering 0. In addition, the high temperature superconductor 23
Even if the traveling vehicle 13 that has finished pinning the magnetic flux to the vehicle accidentally tries to enter the track 12 from the pinning station 40, a force to return the traveling vehicle 13 to the pinning station 40 side is provided in the vicinity of B '. Further, since the gradient of the magnetic potential similar to the above is given also at the end of the pinning station 40, the traveling vehicle 13 does not drop from the end of the pinning station 40.
The pinning station 40 configured as above is
Under the condition that the high temperature superconductor 23 is in the normal conducting state, the traveling vehicle 1
High temperature superconductor 23 when 3 is positioned at the pinning location
The magnetic field generated by the permanent magnet 45 is applied to the high temperature superconductor 23 in such a manner that the magnetic flux density in the inside becomes smaller than the magnetic flux density in the same place in the high temperature superconductor 23 when the traveling vehicle 13 is positioned on the track 12. I am trying.

Next, the operation of the magnetic levitation type traveling device configured as described above will be described.

First, before the running operation is performed,
A traveling vehicle 1 equipped with a high-temperature superconductor 23 in a normal conducting state
Place 3 on spacer 42 of pinning station 40. At this time, since the high temperature superconductor 23 is in the normal conducting state, the magnetic flux emitted from the permanent magnet 45 passes through the high temperature superconductor 23. In this state, liquid nitrogen N is injected into the container 22 through the spout 21 to transfer the high temperature superconductor 23 to the superconducting state. As a result, the magnetic field generated by the permanent magnet 45 that has entered the high-temperature superconductor 23 is pinned in the high-temperature superconductor 23.

After the above procedure, the traveling vehicle 13 is moved to the track 12
Move it up manually. Then, since the magnetic field applied by the permanent magnet 14 on the track 12 is stronger than the magnetic field applied at the pinning station 40, the density of the magnetic flux pinned in the high temperature superconductor 23 is almost the same. The traveling vehicle 13 levitates due to the magnetic repulsive force up to the height at which the magnetic flux density is obtained.

Next, when a start command is given to the controller 34a, the stator winding 18a of the linear induction motor stator 15a is excited at a predetermined frequency by the three-phase output of the inverter device 33a. Therefore, the linear induction motor stator 15a generates a moving magnetic field. When the moving magnetic field is generated in this way, a current in a direction of canceling the moving magnetic field is induced in the high-temperature superconductor 23 mounted on the traveling vehicle 13, and the traveling vehicle 13 is caused by the electromagnetic force due to the interaction between the induced current and the moving magnetic field. Starts running. At this time, since the magnetic field is held inside the high-temperature superconductor 23 mounted on the traveling vehicle 13 by the pinning effect, a guiding force that causes the traveling vehicle 13 to follow the track 12 acts. Therefore, the traveling vehicle 13 floats and runs without deviating from the track 12.

Linear induction motor stators 15a, 15b,
In the section where there is no ..., The traveling vehicle 13 travels by inertia. When the traveling vehicle 13 approaches the linear induction motor stator 15b at the stop position and crosses the front surface of the sensor 31ba, the following stop control is performed by the controller 34b.

That is, as shown in FIG. 4, when the stop command is given and the stop control is started (s ₁ ), any one of the pair of sensors 31ba, 31bb detects the traveling vehicle 13. It is determined (s ₂ ). Next, the linear induction motor stator 15b is fixed so as to generate a moving magnetic field that moves at a predetermined speed from the sensor side not detecting the traveling vehicle 13 toward the sensor side detecting the traveling vehicle 13. child windings 18b inverter - excited by the output of the motor unit 33b (s _3). By this control, the traveling vehicle 13 starts deceleration. Next, it is determined whether vehicle 13 to the stop position in order to investigate whether the progress of both sensors 31ba, 31bb has detected the vehicle 13 at the same time (s _4). Then, in order to confirm the stop of the traveling vehicle 13,
Stop for a predetermined time excitation (s ₅₎ and then, both again sensors 31ba, determines whether the 31bb is detecting vehicle 13 (s _6). At this time, when the traveling vehicle 13 is not in the stop position, a moving magnetic field that moves at a predetermined speed is generated from the sensor side that detects the traveling vehicle 13 toward the sensor side that does not detect the traveling vehicle 13. The stator winding 18b of the linear induction motor stator 15b is connected to the inverter device 33b.
It is excited by the output of (s ₇ ). By this control, the traveling vehicle 13 is returned to the stop position. Thus, vehicle 13 stops excitation of the stator windings 18b when it was confirmed that the stop position in step (s _6), and ends the stop control.

Further, when the stopped traveling vehicle 13 is driven, it is controlled as follows. That is, when the start command is given and the start control is started, the controller 34b
Excites the stator winding 18b with the output of the inverter device 33b so that a moving magnetic field of a predetermined speed is generated in a predetermined traveling direction. In this case, both sensors 31ba, 31bb
The stator winding 18 when the vehicle no longer detects the traveling vehicle 13.
The excitation of b is stopped and the start control is ended.

As described above, since the magnetic field having a predetermined magnetic flux distribution pattern is held inside the high temperature superconductor 23 mounted on the traveling vehicle 13 by the pinning effect, the traveling vehicle 1
The levitation force and the guide force larger than those using the Meissner effect can be applied to the motor 3, and the traveling vehicle 13 can be floated so as not to deviate from the track 12. Also,
When a moving magnetic field having a speed different from that speed is applied to the traveling vehicle 13, a large eddy current is generated inside the mounted high temperature superconductor 23. Therefore, even with a simple structure in which the linear induction motor stator is arranged below the permanent magnet array forming the track 12, a sufficient propulsive force can be applied to the traveling vehicle 13 and the traveling vehicle 13 can be provided as desired. It can run stably at speed. Further, a pinning station 40 having the same height as the orbit 12 is provided in a continuous relationship with the orbit 12, and a magnetic field capable of obtaining the above-mentioned magnetic flux density is applied at this station 40 to pin the magnetic flux to the high temperature superconductor 23. I am trying to let you. Therefore, even in the case of the large traveling vehicle 13, its handling can be facilitated.
