Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a floating railway turnout, and particularly to a floating railway turnout suitable for a traverser system.

, [Background of the Invention] Conventionally, in a so-called guide track type vehicle in which the lateral force of the vehicle body is supported by vertical guide surfaces along the track via tires, etc., the guide surface of the track divider part is supported by the track. The structure is curved to match the linear shape, and care is taken to prevent lateral impact from occurring when a vehicle passes through the turnout. However, as mentioned above, curving the guide surface to match the track alignment requires a mechanism for good guide surface curvature, resulting in a complicated structure and high cost, as well as in terms of maintenance and inspection. However, it also had the disadvantage of requiring a great deal of labor. Such a guide track turnout will be explained with reference to FIGS. 1 to 3. Figure 1 shows the turnout track girder! FIG. 2 is a plan view showing the main line arranged in a linear manner, FIG. FIG. 2 is a cross-sectional view of the vehicle running on the track girder shown in FIG. 2; In the figure, l, 6. 7 is a fixed digit, and 2, 3, and 4.5 are movable digits. 8 is the fixed digit 1+, 6+7 and moving digits 2 to 5.
A guide surface 9 formed perpendicularly on both upper sides of the vehicle body 14 is an auxiliary guide device provided at a position facing the guide surface 8 . lO is the fixed digit mentioned above! .

6.7 and a guide propulsion coil provided below the guide surface 8 of the movable girders 2 to 5, and 11 a levitation coil provided on the inner lower surface of the fixed girder 1, 6.7 and the movable girder 2 to 5. . A magnet is provided on the vehicle body 14 at a position facing the levitation coil 11. Reference numeral 13 denotes a cart disposed below the movable girders 2 to 5, movably supporting the movable girders 2 to 5, and moving on a predetermined trajectory.

In such a configuration, the solid lines showing the outline of each girder in FIGS. 1 and 2 indicate the guide surface 8,
The guide surface 8 must be a straight line or a curved line in the main line state and in the branch state as shown in the figure. Therefore, the guide surface 8 itself is made of a flexible plate, and a mechanism for bending and stretching it using hydraulic pressure or air pressure is required, resulting in an extremely complicated structure.

[Object of the Invention] In view of the above points, it is an object of the present invention to simplify the configuration of a floating railway turnout, reduce costs, and simplify maintenance and inspection.

[Summary of the invention]

By the way, there are various types of floating railways, and one of them, the induced repulsion type, will be explained. In the case of the induced repulsion type, when the vehicle runs at low speed, the vehicle body lateral support force (restoring force toward the center of the track) due to magnetic force is small;
An auxiliary guide device, that is, legs with rubber tires project horizontally to support and guide the vehicle body. On the other hand, when the vehicle travels at high speed, the lateral support force due to the magnetic force becomes sufficiently large, so that lateral support and guidance can be performed only by the leg retraction magnetic force. Regarding the running condition of the turnout section of a floating railway as shown in 2., when the main line is on the main line, i.e. in a straight line, the trains usually run at high speed, and when the train is on the branch, they run at low speed in order to improve the riding comfort for passengers. .

Therefore, if the guide surface that the auxiliary guide device comes into contact with is formed as a curved surface in accordance with the track alignment in the branching state where the vehicle runs at low speed as described above, it is natural that in the branching state, the horizontal direction when passing through the branching section will be Acceleration・3・Speed can be kept sufficiently small. On the other hand, when the track girder having the aforementioned curved guide surface is arranged in a main line state, the horizontal cross section of the guide surface becomes a discontinuous circular arc. but,
On the main line, vehicles travel at high speed and pass with the auxiliary guide device retracted, so even if the guide surface is curved, as long as the guide coil is installed in a straight line, there will be no problem with noise. It is something that can be driven. In addition, when a vehicle runs at low speed with the track girder having the curved guide surface arranged on the main line as an unscheduled operation,
Although the discontinuous arc of the guide surface imparts lateral vibration to the vehicle body, there is no problem because the time taken to pass through the branched portion is short. In this way, the present invention simplifies the structure of a turnout consisting of a plurality of divided movable girders by making the guide surface a curved surface corresponding to the branching state and arranging the guide coil in a straight line. It was designed so that it could be done.

[Embodiments of the invention]

Next, an embodiment of the turnout according to the present invention will be described with reference to FIGS. 4 and 5. In the figure, 4, 16 and 21.22 are fixed digits, which are similar to those on the Wffiff side. Reference numerals 17.1g and 19.20 are movable girders, and the difference from the above-mentioned conventional examples of movable girders 17 to 17 is that the guide surfaces are formed into curved surfaces in accordance with the branching state shown in Fig. 4, and they always remain as they are. The point is that it is in a state of

Note that the guide coils of the movable girders 17 to 20 are arranged in a straight line.

In the configuration shown in No. 2, in the main line state in which the movable girders 17 to 20 are arranged in a straight line, the guide surface of each movable girder 17 to 20 becomes a discontinuous circular arc curve, as shown in FIG. However, in the case of the main line, the speed at which vehicles pass through the turnout is usually high, and there is no problem because the left and right guidance is supported by magnetic force and no auxiliary guidance device is used. . Next, under the condition of the main line, there are exceptional cases in which vehicles use auxiliary guidance devices to pass at low speeds, but in this case, the distance through the turnout is relatively short and the vehicle passes through it in a short period of time. It is not a problem even if there is vibration.

On the other hand, when the If moving girders 17 to 20 are arranged in a branching state as shown in FIG. Therefore, you can pass through it without any problems.

According to such a configuration, the guide surfaces of the movable girders 17 to 20 are always formed as curved surfaces, and there is no need to switch to a straight line or a curved line as in conventional ones, and this complicated configuration is not necessary. It has not been done.

Therefore, the configuration of the movable girders 17 to 20 is very simple.
This reduces costs and simplifies work such as temple maintenance inspections.

〔Effect of the invention〕

As explained above, according to the present invention, the configuration of the movable girder can be improved by making the guide surface of the movable girder a curved surface and arranging the guide coils in a straight line.
