Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-route turnout for a guide track in which vehicles are supported by rubber tires or air floating pads. By bending a turntable that can rotate at its center of rotation, and as the rails installed on the turntable bend to form a track that guides the vehicle, a track path other than 180° can be formed. This corresponds to a turntable. The present invention relates to such a multipath switch.

BACKGROUND ART Turntables in which straight tracks are provided on a turntable have been known for a long time, not only for the purpose of changing the direction of railway steam locomotives, but also for having the function of creating many track routes.

However, in the structure of this known turntable, as shown in FIG. 1, a rail 2 is provided on the turntable 1.
Fixed rails A, B, C, which can be connected to the turntable.
D, E; A', B', C', D', E' are provided. The turntable and rails are straight and can form a track path.
Only specific orbits are all located at 180 degrees, and in addition to the illustrated D-O-D', A-O-A', B-O-B',
Although it is possible to connect C-O-C' and E-O-E' to form multiple paths, it is not possible to obtain branch paths other than at 180° positions. Although the rails are shown as one solid line, the same applies to the case where two rails are provided on one track.

In addition, if the gist of the idea of ``3-line branching device'' of Utility Model Publication No. 51-39922 is added to the turntable to enable multi-route branching, as shown in Figure 2, a curved path can be installed on the turntable 3. There are three types of rails: 4, curved rails 5, and straight rails 6. When using curved rails 4, the routes are C-E', B-D', and A-C'. , On the other hand, when using the curved track 5, the route is C-A',
At D-B' and E-C', routes other than the 180° relative position are formed in this way, and a multi-route branching function is obtained, but the turntable has three types of rails on it, so it has a large width. In short, the structure is complicated, and there are also drawbacks such as requiring an excessively large movement space (a) for the turntable as shown by the dashed line. Also, the one shown is
Although the case where the route is branched to a route 2 pitches adjacent from the 180° relative position is shown, it is also possible to branch to a route 1 pitch adjacent. However, in that case, it is necessary to make the total length of the turntable longer than that shown in the drawings to prevent interference between the curved track and the direct track.

Although the above-mentioned conventional technology has the above-mentioned problems, the rubber tire support type vehicle and the air floating pad support type vehicle previously proposed by the present inventor are conventional techniques that can be used to improve these problems. Patent Application No. 55-2881 (Japanese Patent Application No.
(Refer to No. 56-99853) There is a ``turnout'' in Japanese Patent Application Laid-Open No. 58-33602 that can be most effectively used in the ``Small Orbit Cross Section Trajectory Device''. This is a device in which the rails installed on the roadway device bend as the roadway device bends, forming a turnout that guides the vehicle.

The present invention has been made in view of the above, and is intended to be versatile by utilizing the ``turnout'' disclosed in Japanese Patent Application Laid-Open No. 58-33602. The object is to provide a multi-path turnout that enables multi-path branching operations with a new and simple configuration and requires less planar space occupied by movable parts.

The configuration consists of a guide track turnout having a running track for rubber tires and/or air floating pads supporting the vehicle and at least one guide track arranged parallel to this running track, in which a branching curve is formed. A bending running path device comprising a first running path and a second running path each having a structure in which each horizontally rotates in the direction of a required track route about a point that substantially coincides with an interpoint as a center of rotation, and a bending running path device on this bending running path device When the first and second running paths do not bend relative to each other, they are linear, and when they bend, they curve accordingly to form a branching curve. at least one flexible guide rail having both ends located outside the branch curve; one of the ends of the flexible guide rail is constrained to a first running path and the other to a second running path; 1. A multi-path turnout, characterized in that it includes a device for a branching flexible guide rail consisting of a fixture and a branching flexible guide rail.

The present invention will be explained below using examples shown in FIGS. 3 to 7.

FIG. 3 is a plan view showing one embodiment of the present invention.
A bending running path device consisting of a first running path 7 and a second running path 8 having a structure that horizontally rotates around a point, a flexible guide rail 9 disposed on this bending running path device, and its A multi-route turnout is constituted by a branching flexible guide rail device consisting of a fixture 10 that restrains one end of both ends to the first travel path 7 and a fixture 11 that restrains the other end to the second travel path 8. are doing. 1st
When the traveling path 7 and the second traveling path do not bend relative to each other, they are linear, and when they bend, they curve as shown in the figure to form a branching curve with the point O as the interpoint. ing. In this embodiment, the structure is such that it can be bent up to 2 pitches from a relative position of 180 degrees. The situation shown is that it originates from D, crosses C' from D', and is located two pitches to the right of B'. A-E and A'-
E' is a fixed guide rail connected to the respective flexible guide rail 9. The route in this example is
A', B', C' for A, A', B', C' for B,
D′, A′, B′, C′, D′, E′ for C, B′, C′, D′, E′ for D, C′, D′, E′ for E. In this way, many routes can be branched. Note that if the first running path 7 and the second running path 8 are bent by two pitches or more from 180 degrees relative to each other, there is a risk of damaging the flexible guide rail 9, so the bending should not be excessive. It is necessary to either provide a mechanical stopper such as this, or add an interlock to the operation control.

FIG. 4 is a cross-sectional view of a specific embodiment of the present invention, in which there is a first running path 7 or a second running path 8 having a structure that rotates horizontally, and a flexible guide rail 9, and one of the both ends thereof. Fixture 10 for restraining the vehicle to the first traveling path
Alternatively, there is a fixture 11 that restrains the second travel path.

FIG. 5 is a plan view of another specific embodiment of the present invention, which has a branching function called a so-called double slip switch. That is, it has four routes: FG', FF', GG', and GF'. In this embodiment, the branching angles φ ₁ and φ ₂ are not equal and φ ₁ < φ ₂ , so the required length of the horizontally rotating running path is also different, and the length of the first running path 12 is different.
l ₁ is longer than the length l ₂ of the second running path 13. All running tracks have one track on each side, with a flexible guide rail 9 and a fixed guide rail 1 in the center of the track.
4, 15, 16, and 17 are provided. Both ends of the flexible guide rail 9 are restrained by fixtures 10 and 11 to their respective travel paths. The radius of the branching curve in path F-G′ is R ₂ , and the radius of the branch curve in path G
The branching curve radius at −F′ is R ₁ and the flexible part of the flexible guide track 9 is constant, so R ₁ φ ₁ =
R ₁ > R ₂ due to the relationship R ₂ φ ₂ . Note that the path G-G′ is not a straight line but has a branching curve radius R ₃ , R ₃ (φ ₂ −
The relationship is φ ₁ )−R ₁ φ.

All of the above embodiments have been described with a guide rail in the center, but when one guide rail 18, 18' is provided on each side of the track as shown in FIG. 6, or as shown in FIG. Guide rails 1 on both sides of
9 and 19' can also be implemented in a structure in which the linear motor reaction rail 20 is arranged in the center. The traveling path 21 in FIG. 6 has a one-track, one-plane structure. The running path 22 in FIG. 7 has a structure divided into left and right sides.

Of the fixing devices 10 and 11 at both ends of the flexible guide rail, one of the fixing devices 10 and 1 is preferably configured to allow sliding in the longitudinal direction of the flexible guide rail.
The center of rotation of either the first or second running track is configured to be slidable in the longitudinal direction of the track, and the flexible guide rail is prevented from sliding in the longitudinal direction. It can be adapted to accommodate changes in length.

The part forming the branching curve of the flexible guide rail is
If the cross section has approximately constant horizontal bending stiffness over its entire length, the branching curve will be a circular curve, and the portion forming the branching curve will have horizontal bending stiffness that decreases from both ends toward the center over its entire length. If the central part has a cross section with a constant horizontal bending stiffness, the branching curve can have relaxation curves at both ends and a circular curve at the center. As shown in FIG. 4, FIG. 6, and FIG. 7, there are one to three rail arrangement examples, and these can be used as appropriate for either a guide rail or a reaction rail for a linear motor. In this respect, it is similar to the case of the turnout disclosed in Japanese Patent Application Laid-Open No. 58-33602 mentioned above.

In a multi-route turnout, even on general railways, the left and right rails intersect in a complex manner, making it difficult to create a railway signal track circuit in this area. The left and right running paths are always independent, and the left and right running paths never intersect, so
A track circuit can be easily created by electrically insulating the left and right running paths. In this respect, it is possible to solve a more difficult problem than the above-mentioned switch of Japanese Patent Application Laid-Open No. 58-33602.

According to the configuration of the present invention as explained in each of the above embodiments, a simple configuration consisting of only the first and second running paths and a guide rail whose both ends are restrained and supported by fixing devices on the running path can be used. It is possible to obtain branching of the route,
In addition, the movable parts have the effect of reducing the space occupied by the movable parts, and the intended purpose can be well achieved.

In addition, the branch curve is a curved flexible guide rail, and can be a circular line or a circular curve with transition curves at both ends, so the guidance of the vehicle is extremely smooth, and the track has reaction rails for linear motors. It has many advantages, such as being able to be applied to the branching of conventional railways, and making it easy to implement railway track circuits that have been used extensively in conventional railways.
