Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway branching device, and more particularly to a branching device used for both wheels and both flanged wheels (patent application of Apr. 21, 1995).

[0002]

2. Description of the Related Art In a conventional branching device, a reference line main rail and a branch line main rail are fixed at points, and the reference line lead rail and the branch line lead rail are tapered tongue rails. Was oscillated with the rear end of the point as a fulcrum, and was branched by coming into close contact with and leaving the main rail. Further, in the crossing portion, a reference line (branch line) lead rail is extended to form a branch line (reference line) guard rail,
Furthermore, the short nose rail and the long nose rail were integrated.

Since all the wheels of the currently used ordinary railway are two-wheel one-flange wheels, the branching device has the above-described structure correspondingly. As a result, the "two-wheel, both-flange wheels" (filed on April 21, 1995), which was devised to improve running stability at high speeds, is
If the two rails are in close contact with each other or are integrated, or if the rail of the reference line (branch line) is extended and becomes the guard rail of the branch line (reference line), climb onto the rail and
I will take off.

[0004]

Both wheels and two flange wheels can travel only on one independent rail. This is similar to that a grooved door car with sliding doors can run only on one door rail. In the point section and the crossing section, the two rails should not be in close contact with each other or intersect with each other, and the branch should be a single rail.
This is the first issue.

Since the current branching device has a tapered tongue, it is easily worn and has a problem in strength.

Further, there is a broken line at the front end of the crossing of the current branching device, which causes problems such as noise, vibration, damage to rails and wheels due to impact, and speed limitation.

[0007]

In order to achieve the above-mentioned object, in a switch for both wheels and two flange wheels of the present invention,
Four rails, which are the same as a normal rail, are arranged in the point portion and laterally moved, and two of them are connected to a reference line and the other two are connected to a branch line. The four rails are fixed to a plurality of rolling rods, and the rolling rods are supported by a rolling rod support portion so as to be reciprocally movable in the sleeper direction. A four-wire type lateral branching device consisting of four rails and a plurality of rolling bar is rolled by a rolling device for lateral rolling device and locked by a locking device for lateral rolling device. .

In the crossing section, two rails intersect each other. In the present invention, however, one rotary rail is fixedly mounted on the rotary table, and the rotary table is rotated so that the rotary rail becomes the branch line lead rail. To the branch line sub rail (see FIG. 1), or to connect the reference line lead rail and the reference line sub rail (see FIG. 2).

[0009]

1 and 2 are plan views for explaining the operation according to the embodiment of the present invention. Fig. 1 shows a state in which it is rolled to a branch line. The four-wire type lateral branching device at the lower part of the figure is laterally moved to the left, and the main line rail is on the side of the branch line main rail. It is connected to the branch line main rail (branch line lead rail) through the moving rail (branch line lead rail side traverse rail). The one-line rotary crossing in the center crossing portion of the figure is turned clockwise, and the rotary rail is connected to the branch line lead rail and the branch line sub rail.

FIG. 2 shows a state of being branched to a reference line. The four-wire type lateral branching device at the bottom of the figure is laterally moved to the right,
The main line rail is connected to the reference line main rail (reference line lead rail) via the reference line main rail side movement rail (reference line lead rail side movement rail). Further, the one-line rotary crossing in the center of the figure is turned counterclockwise, and the rotary rail is connected to the reference line lead rail and the reference line sub rail.

In this way, the two wheels and the two flange wheels that have traveled on the two main rails are branched and travel on one independent rail.

I am using.).

[0035]

Since the present invention is configured as described above, it has the following effects.

Each of the above-described embodiments is composed of two independent rails, and in that respect it is no different from two main rails. Therefore, in addition to a vehicle having both wheels and both flange wheels, a vehicle having currently used two wheels and one flange wheel can also travel. Therefore, it is possible to run an ultra-high-speed train using two-wheel and two-flange wheels on an existing route simply by replacing the turnouts at overtaking stations, garages, factories, etc. with the turnouts shown in the embodiments of the present invention. It is cheaper than constructing a line.

Since there are no tapered tongue rails or broken gauge lines in the crossing portion found in the current branching machine, the wear resistance is high and the noise is low. Further, since there is no broken line between the gauges, the guardrail is not necessary, and the contact noise between the rear surface of the wheel and the guardrail does not occur. In addition, since there is no broken gauge line, there is no need to limit the speed on the localization side of the straight line, which contributes to the improvement of train speed.

Since there is no crossing portion having a tongue rail or a broken line between gauges, the rail need only be a role money, that is, a normal rail, and it is inexpensive and robust in terms of material and heat treatment.
