Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a track structure, and more particularly to a track structure in which a power line is provided below the track.

<Prior Art> Currently, the following two systems are adopted as a current collection system for electric trains.

(A) Overhead system This is a system in which a train line (trolley line) is stretched over the track and brought into contact with a pantograph installed on the roof of the train to collect electricity.

(B) Third rail system In addition to the running rail, a rail with a voltage applied will be installed on the side of the track.

Electric power is collected from the rails through collecting shoes provided on the side surface of the vehicle.

<Problems to be Solved by the Present Invention> The above-described current collection technique has the following problems.

(B) The overhead wire system not only spoils aesthetics,
It takes a huge amount of money to install a supporting column and a suspension device for constructing the trolley wire.

(B) Further, in the case of the overhead line system, the overhead line is exposed, and there is a danger that it will be touched by construction machinery or workers by mistake, which is extremely dangerous.

(C) In the case of the third rail system, there is a risk of accidental touch because the rail through which high-voltage current flows is located on the ground.

<Purpose of the present invention> An object of the present invention is to provide a structure of a track that can be safely passed by preventing a pedestrian or a wheel of a bicycle from being caught in a groove formed on the track.

<Structure of the Present Invention> An embodiment of the present invention will be described below with reference to the drawings.

<A> Current collecting method In the present invention, the power transmission line is arranged below the track in consideration of aesthetics and safety.

Then, a current collecting shoe is attached downward to the bottom of a track car such as a tram, and the current is collected below the track.

The specific orbital structure will be described below.

<B> Orbit Structure FIG. 1 shows the orbit according to the present invention.

In the 1-road board, 2 is a storage box, 3 is a rail, 4 is a power line, and 7 is a current collecting shoe.

[Storage Box] The storage box 2 is not only a support for the rail 3 but also a protector for wiring the power line 4 in the ground.

The storage box 2 has a continuous space 21 inside, and a slit 22 which is continuously opened along the laying direction of the rail 3 is opened on the ceiling surface thereof.

The slit 22 is opened in the center of the two sets of rails 3 laid on the upper surface of the storage box 2.

The storage box 2 is formed by embedding a divided or integrated block body that has been formed to a certain size in a factory or the like in the roadbed 1, or by forming a formwork and placing concrete on site to provide continuity. To do.

Further, the storage box 2 is designed to have a strength sufficient to withstand a load applied when the train is running.

Further, a drainage groove 23 is provided on the bottom surface in the space 21 so that the water can be drained to the outside of the box.

In addition, a manhole is provided in the storage box 2 for maintenance and inspection in the space 21.

[Power Line] The power line 4 is attached to the space 21 formed continuously with a constant distance from the perpendicular of the slit 22.

The power line 4 is installed near the side wall, avoiding directly under the slit 22 in order to avoid blowing rainwater.

As a specific mounting method of the power line 4, for example, as shown in FIG. 1, it is mounted on a wall surface through an insulating bracket 64, or as shown in FIG. 4, two support links 61 and 62 are used. It is also possible to secure the verticality of the power line 4 by using the intermediate link 63, and to arrange the push line 6 on the back surface of the support link 61 so that the power line 4 can be constantly pressed against the current collecting shoe 7. Is.

[Closing Body] If the slit 22 is left open, rainwater or foreign matter may enter, or the foot of a pedestrian or the wheel of a bicycle may be caught.

Further, since the current collecting shoe 7 cannot move inside the slit 22 when the slit 22 is completely closed, it is necessary to close the current collecting shoe 7 in a state where the current collecting shoe 7 is allowed to move.

Therefore, in the present embodiment, the following closing body 5 is adopted as the closing means for the slit 22.

That is, as shown in FIGS. 2 and 3, the closing bodies 5 each including two discs 51 as a set are arranged on the slit 22 in abutment with each other.

As the disk 51, an iron plate or the like having a strength sufficient to withstand a load such as a pedestrian or a bicycle is used.

In addition, a spring 52 for urging the discs 51 and the storage box 2 is interposed between the discs 51 and the storage box 2 in a direction in which the discs 51 approach each other.
The slit 22 is configured to be openable and closable.

Then, when the current collecting shoe 7 passes, it spreads while passing the spring force of the spring 52 connected to both discs 51,
After passing through the current collecting shoes 7, the slit 22 is again provided by the spring 52.
Both discs 51 face each other and close up.

In the above embodiment, the two disks 51 are butted against each other, but the closing body 5 may be composed of only one disk 51.

<C> Structure of current collecting shoes The current collecting shoes 7 are attached downward to the bottom of a railcar such as a tram.

The current collecting shoe 7 is a contactor that comes into contact with the power line 4 provided in the space 21, and is formed of a narrow conductive plate.

The lower part of the current collecting shoe 7 is bent and formed so as to come into contact with the power line 4.

Further, the current collecting shoe 7 can be provided with a function of facilitating the spread of both disks 51 of the closing body 5.

That is, a method in which a wedge-shaped projection 8 having a curved surface is projected on the outer circumference of the current collecting shoe 7 (FIG. 5), or a disk-shaped rotating body 9 is rotatably supported on the outer circumference of the current collecting shoe 7. (Fig. 6)
Etc. can be adopted.

<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.

(A) Before and after the current collecting shoes pass, the closing body surely closes the slit formed on the track.

Therefore, it is possible to reliably prevent a foot of a pedestrian, a narrow tire, or the like from accidentally entering the slit.

(B) Since the closing body has a simple shape, it can be easily manufactured and attached.

(C) The scenery is improved by wiring the power line that was exposed on the ground until now to the lower part of the track.

(D) The power line is housed in a concrete box that forms the track.

Therefore, the occurrence of an electric shock accident can be prevented, and the power line can be safely wired.

(E) In the prior art, there is a mechanism for opening and closing the slit by deforming an elastic closing body (Actually, Shokai 55).
-127626).

However, in the case of such a conventional technique, while a person, a bicycle, or the like repeatedly travels over the obstruction body, the obstruction body may not be able to bear the load, and the obstruction body may fall into the slit, which is extremely dangerous. is there.

On the other hand, according to the present invention, since the disk is slid by the spring force, the obstructing body itself does not need a deforming force.

Therefore, a rigid member such as an iron plate can be used for the closing body.

Therefore, unlike the related art, the closing body does not fall into the slit, which is significantly superior to the related art in terms of safety.
