[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 8.

First, in Figure jg3, 5A in the figure, jBFi U of the main line fixedly arranged in a straight line with the branching device of the present invention interposed.

5B and 5C have the same configuration as the tracks shown in FIG. 2 described above, and the superconducting magnetic levitation vehicle shown in FIG. 2 can levitate and run as a guide.

Here, 13 in FIG. 3, 13B, 13C.

13D, 141.14B, 14C, and 14D are short branching tracks constituting the branching device of the present invention, and these are straight lines connecting the main line tracks 5A and 5B as shown in imaginary lines on the left and right, respectively. The lines are arranged so as to be movable and changeable from the arrangement state to a bent line arrangement state along an arc of a predetermined curvature so as to connect the main line track 5A and the branch line track 5C as shown by the solid line. In other words, the above branch trajectories JjA~13D and J4A~14
D is an L that looks like the U-shaped cross-section track in Figure 2 is divided into two left and right from the center of the track, as shown in Figures 3, 4, and 5.
They are arranged in the form of short blocks with a cross-section facing each other on the left and right sides. Furthermore, each of them individually moves the wheels (
(not shown) is mounted on a movable trolley 11 via a support plate 20t, and is connected to the tip of a piston rod 19a of a hydraulic cylinder 19 protruding from the fixed space 18 on the lower side of each via a holder 20t. By the operation of the hydraulic cylinders 19, they are moved back and forth together with the trolley 17, and are arranged in a straight line as shown by the imaginary line in FIG. It is designed to convert to an array state. In addition, as shown in Figure 4, nine trolleys 1
A placket 21 is protruded from the outside of the plate 7, and a force pedestal 23 is provided on the top surface of the placket 21, which can be rotated around a pin 22. It is supposed to move. Further, the carriage 17 is adapted to be held by a positioning mechanism (not shown) such as a knock pin at the limit of its movement.

In addition, the above left and right branch tracks 13A to 13D and J4A to
14D are each short, but the length of each trajectory is an integral multiple of the arrangement pitch of the propulsion guide coils 24, which will be described later, so that the propulsion guide coils 24 may be discontinuous or leave a large distance from the adjacent ones. At the same time, as shown in Fig. 3, when the track group is arranged like a broken line along an arc, the branch track 13D at the tip of the track group on the outer track side is pressed against the others. It is half the length, and with this, the left and right, that is, the outer track side and the inner soft side branch track 13, 13B
, 13C and 14, 14B, 14C, and 14D are arranged so as to face each other in a half-pitch shifted state, so that the left and right guide wheels, which will be described later, maintain a constant interval of 25°25. It has become.

In addition, the left and right branch tracks 13 to 13D and 14 to 14
As shown in FIG. 3, it is assumed that four Ds are arranged in rows on each side, but this number is small for convenience of explanation, and a larger number will be arranged in an actual branching device.

As mentioned above, left and right branch tracks 13A to 13D and J4A to 1
4D, as shown in FIGS. 4 and 5, a plurality of levitation coils 28 are embedded in the upper surface of the bottom wall 26 in the same way as in FIG. 10
A tread surface 29 on which a person can land and roll is configured. Further, a plurality of propulsion guide coils 24 are embedded in the inner surface of the side wall 30 and arranged in a row. Further, a guide rail 25 for rolling the guide wheel is provided on a part of the inner surface of the side wall 30 so that the guide wheel 12A can roll on the ground.

To explain these in more detail, the levitation coil 28 and the tread surface 2
9 is the same as that shown in FIG. 2, but the propulsion guide coil 24 is shown in FIGS. As shown, the middle of each coil vertical side portion 24a, 24b is the side wall 30.
Curved inward, other upper and lower horizontal sides of the coil: 2
4c, 24'd 75, it is constructed flat like the one in FIG. In addition, the guide rail 25 for rolling the guide wheel is a horizontally elongated one having a generally trapezoidal cross section with a wide inner surface and an intermediate sandwiched outer surface, and its inner surface is *ai,
the inner surface of the so and the upper and lower horizontal sides 24c of the propulsion guide coil 24;

It is housed in the recess 31 so as to be normally flush with the inner surface of the recess 24d. Since this guide rail 25 receives 7 lux from a strong superconducting electromagnet, it is preferably made of a non-magnetic material as well as a non-conducting material. The OUT guide rail 25, which is made of a molded material such as FRP, is required to have excellent flexibility in the tth direction of curvature, which will be described later. , 24b, the thin part 25a looks like it has been scratched from the back □ side as shown in FIG.
In other areas where it is spatially easier to form the recess 3, the hollow recess 31 is made deeper and the guide rail 25 itself is made thicker.

Here, the left and right branch tracks 13A to 13D and J4A to
The guide rails 25 for rolling the guide wheels, each of which is housed in the recess 31 of 14D, are arranged when the left and right branch tracks 131 to 13D and J4A to 14D are arranged in a straight line as shown in the imaginary line in Figure 3. is straight and true along the straight line, and when the left and right branch tracks 131 to 13D and 141 to 14D are arranged in a polygonal line along an arc of a predetermined curvature as shown by the solid line in Fig. 3, it runs smoothly along that arc. They are each supported by a support mechanism 32 so as to be curved and continuous, that is, to form a smooth continuous curved surface.

Regarding the support mechanism 32, as shown in FIG. 5 and FIG. are provided protrudingly, and each of the operating rods 33 is installed on the side wall 30 and is slidably fitted into a guide seat 34 to pass through the side wall 30 toward the back surface thereof. And springs 3, 6 are provided between each operating port, 7 langes 35 provided integrally with the door 33, and the guide seat 34.
, the guide rail 25 is always pulled back to the side of the back side, and as a result, the guide rail 25 is housed in the recess 31 and the inner surface on which the guide wheel 12k contacts the side wall 30 and the inner surface of the propulsion guide coil 24. It is a trap so that it is supported in a flush position. Further, a slider 37 is provided at the end of the operation port door 33, and a cylindrical cam 40 is provided below the slider 37, supported by bearings 39, 39 on a pedestal 38 protruding from the side wall 30. The slider 37 is slidably fitted into the cam groove 401 of the cylindrical cam 40, and a worm wheel 42 is provided at the protruding end of the shaft 41 of the cylindrical cam 40, and a drive having a worm 43 that meshes with the worm wheel 42. Axis 44 @ wall 30
The drive shaft 44 is provided through a suitable support member (not shown), and is rotated by a prime mover such as a motor (not shown). As a result, the rotation of the cylindrical cam 40 allows the operation port 33t to push out the idle rail 25 by a predetermined stroke against the genera 36.

In addition, when the support mechanism 32 is in a state where the branch track is arranged in a polygonal line, the guide rail 25 cannot be deformed in a curved manner by pushing out the guide rail 25 at all locations such as its operating port, door 33, etc. 30, a part of the guide rail 25 is a fixed point that does not protrude and deform while being retracted into the recess 31, and the other part is fixed to the recess 3 of the side wall 30.
It is necessary to push it out from inside 1 and displace it by a predetermined amount depending on each part. For this reason, when the left and right branch tracks JjA to 13D and J4A to 14D are arranged in a broken line as shown in Figures 7 and 8, each branch track 131 to 13D on the outer track side as shown in Figure ID rail 33...
For each track 13, the intermediate part between 13B and I3C is fixed point 45, 45B, 45C, and in the track 13D, which is half the length of the leading edge, the connecting end part of the branch line to track 5C is fixed point 45. 45D, ~4 to each fixed point 45
Unlike the movable type shown in FIG. 5, the operation rod 33' that supports 50 parts is of a fixed type that does not protrude when the guide rail 25f is retracted, and the operation rod 33' that supports all other parts is of a fixed type. All of the guide rails 25t are of a movable type that protrudes and displaces the guide rail 25t by a predetermined amount according to the curvature by the aforementioned cam action. On the other hand, as shown in Fig. 8, the guide rails 33 of each branch track J4A-14D, which are on the inner soft side, are
The operation rod 33', which supports the respective fixed points 45A to 460, has fixed points 46 and 46B, 46C, and 46D at both end portions of 14B, 14C, and 14D on each track 14, respectively, and is of the fixed type as described above. Each operating port and door 33 that support other parts are movable as described above.

With this, each of the guide rails 25 on the outer track side (excluding the guide rail 25 on the tip track 13D) is moved to protrude on both ends while retracting the middle part to create a smooth arc shape (curved, inner soft). Each of the guide rails 25... is adapted to be displaced upwardly in the middle with both ends retracted and curved into a smooth arc shape.

In addition, the left and right branch tracks 13A to 13D and 141 to J
4D is a guide rail 25 for rolling each guide wheel, since the distance between adjacent ones changes between the linear arrangement state and the polygonal arrangement state shown in Fig. g'3.
The required length of ... will also change. For this purpose, each guide wheel -
As shown in FIG. 4, the rolling guide rails 25... have both ends 47 formed into finger shapes or diagonal cuts,
Both ends of adjacent ones are overlapped and connected so as to intertwine with each other, and left and right branch tracks 13A to 13 are connected.
The guide wheels 12k can be continuously rolled even when the wheels D and 14A to 14D are arranged in a linear manner or in a polygonal arrangement.

In addition, the left and right branch tracks 13 ~ 13D and J4A ~ 14D
Since it is a problem if there is a gap between the landing and rolling treads 29 of the running wheels 10 adjacent to each other, a metal plate such as a non-metallic finger plate such as FRP (not shown) is provided to ensure that the running wheels 10 are continuous. This allows for smooth transfers.

In addition, there are provided a power supply device for the propulsion guide coil 24 and the levitation coil 28, various signal interfaces, and other devices necessary for configuring the entire branching device.

To describe the operation of the branching device having the above-mentioned configuration, first, the left and right branching tracks 13A to 13D are connected as shown by imaginary lines in FIG.
and 14A to 14D are arranged in a straight line, the U-shaped cross-section tracks 5A and 5B of the main line are connected directly, and at this time, the left and right branch tracks 13A to 13D and J4A to 14
The guide rail 25 for rolling the guide wheel D... is the side wall 30
It is drawn into the recess 31 and is flush with the inner surface of the propulsion guide coil 24. If the levitation coil 28 and propulsion guide coil 24 are energized in this state, the superconducting magnetically levitated vehicle that has been levitating and guiding on one U-shaped cross-section track 5A of the main line will continue to be levitating and guided in substantially the same way. It becomes possible to travel straight at high speed and pass to the other U-shaped section track 5B of the main line. Note that as part of this soil removal, the coil upper and lower sides 24 of the propulsion guide coil 24 that provide the left and right guiding force of the vehicle
Since the tracks 5A and 24d are exactly the same as the U-shaped cross-section tracks 5A and 5B of the main line, the guiding characteristics of the vehicle remain unchanged. Coil vertical side portion 24m, 2 of one side propulsion guide coil 24
4b is partially curved, which increases the distance between the vehicle bogie frame and the superconducting electromagnet 4, resulting in a reduction in propulsive force. Since there is no branching device, the reduction in propulsive force is only slight, and since the total length of the train is longer than the total length of the branching device, there is no problem in continuing to drive straight at high speed. In addition, in this state, the traveling wheels 10 are rolled to land on the tread 29, and the guide wheels 12k on both sides are brought into rolling contact with the inner surface of the guide rail 25, so that the wheels travel straight at a low speed. It can be done without any interruption.

Next, the hydraulic cylinders I9 are driven by each truck 17 to move the left and right branch tracks 13 to ~13D and 14fi.

14D is moved to change to the bent arrangement state along the circular arc of the predetermined curvature shown by the solid line in Figure 3, the U-shaped cross-sectional track 5A on one side of the main line and the U-shaped cross-sectional track 5C on the branch line are - In this state, the left and right branch tracks 13 are connected - 13
Idrail 2 is for rolling guide wheels D and 14A to 14D.
5. The support device 411f32 fixes the points 451 to 45D and 46A to 46D shown in FIGS. 7 and 8.
The part is side I! The remaining portions are kept retracted into the recesses 3 of No. 30, and the other portions are pushed out by an appropriate amount so that they are smoothly curved and arranged continuously along the arc of the predetermined curvature. Moreover, the guide rail spacing between the left and right sides, that is, the outer track side and the inner soft side, is constant over the entire length in the traveling direction. In this state, the superconducting magnetically levitated vehicle that has been traveling on one U-shaped cross-section track 5A of the main line is made to travel at a low speed with wheel running. With this, the vehicle is moved to the treads 29 of the left and right branch tracks 131 to 13D and 14A to 14D.
As the traveling wheels 10 roll upward one after another, the guide wheels 12A on both sides roll into contact with the inner surfaces of the left and right guide rails 25, which are continuously curved smoothly toward the inner and outer tracks. As a result, the vehicle is smoothly guided along the arcuate curve on the bifurcated track arranged in a polygonal line arrangement, and is able to run on its wheels toward the U-shaped cross-section track 5C of the branch line.

Note that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways. For example, the idle rails 25 for rolling the guide wheels may be provided independently for each of the left and right branch tracks, but they may be constructed of a single long continuous rail for the left and right tracks.

The support mechanism 32 for the psychokinetic train 25 may be as shown in FIGS. 9 and 10.

In other words, in the one shown in FIG. 9, a cam 40A is provided directly on the drive shaft 44, and the rotation of this cam 40 presses the operation port and the 7 langes 35 of the door 33 to displace the skeleton rod 33. Since the shaft 44 can rotate by a maximum of about 180 degrees, the rotation can be reduced by an electric motor, or an arm can be extended from the drive shaft 44 and rotated by about 90 degrees by a hydraulic cylinder. The one in Fig. 10 does not use a drive shaft, but instead uses the piston rod 4 of the hydraulic cylinder 48.
8*t- direct operation port, connected to 7 langes J6A of door 33, pressure oil from hydraulic pressure source 49 is supplied to cylinder 48 by automatic operation of pulp 5o, and piston rod 481 connects to the operation port, door 33t- It is configured to push out a predetermined stroke, and in this case, the pushing stroke may be appropriately regulated by the stroke mother 51.

As described in detail above, this invention enables a superconducting magnetically levitated vehicle that travels at high speed on a U-shaped cross-section track while being levitated and guided by superconducting electromagnets to pass straight through the track at high speed. On the other hand, it is extremely useful as a track branching device for a superconducting magnetically levitated vehicle, which allows the vehicle to run at low speed along a smooth curve while rolling its guide wheels, allowing the vehicle to branch off smoothly to another route. becomes.
