Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to a power supply/collection device for a rail vehicle.

<Conventional technology> Currently, the following two methods are used for the last train train.

(a) Catenary line system A method in which overhead contact lines (trolley lines) are stretched above the tracks, a pantograph is installed on the roof of the train, and the pantograph is brought into sliding contact with the trolley line to collect current.

(b) Third rail method A method in which a power supply rail is installed on the side of the track, and current is collected by placing collector shoes on the side of the train and sliding the collector shoes against the power supply rail.

<Problems to be Solved by the Present Invention> The conventional current collection techniques described above have the following problems.

(b) In the case of the overhead wire system, not only does it disturb the aesthetic appearance, but it also requires a huge amount of cost to install the supports and suspension equipment for installing the trolley wire.

(b) In the case of the overhead wire system, the trolley wire is exposed, so there is a risk that construction machinery or workers may accidentally touch it, which is extremely dangerous.

(c) In the case of the third rail system, the rails carrying high voltage current are located on the ground, so there is a risk of accidentally touching them.

<Object of the present invention> The present invention has been made in view of the above points, and its object is to provide a feeder/railway vehicle for a track vehicle that can improve the landscape and also allow the smooth movement of current collector shoes.
An object of the present invention is to provide a current collector.

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

<A> Supply and current collection device for rail vehicles Figure 1 shows an example of a power supply and current collection device for rail vehicles.

The power supply/collection device is composed of a power line 4 for power supply and current collector shoes 7 attached to the train side.

A storage box 2 made of concrete is supported by a roadbed 1, and a rail 3 for running a train is installed on the top of the storage box 2.
3 has been installed.

The main members will be explained below.

<B> Installation Space The power line is installed on the wall of a wiring space 21 that is continuously formed inside the storage box 2.

A continuous slit 22 is formed above the wiring space 21 along the direction in which the rail 3 is laid, and the slit 22 is closed by a closing body 5, which will be described later.

Note that a manhole may be provided in the middle of the storage box 2 as an entrance for maintenance and inspection inside the storage box 2.

<C> Power line In order to avoid contact with rainwater, the power line 4 is attached to the wall avoiding a position directly below the slit 22 in the wiring space 21.

FIG. 3 shows an example of how the power line 4 is attached. A push spring 6 is arranged on the back surface and biased toward the current collector shoe 7 side.

<C> Closure If the slit 22 in the wiring space 21 is left open, there is a risk that rainwater or foreign objects may get in, or pedestrians' shoes or bicycle tires may get caught, so it is necessary to close it.

If the slit 22 is completely closed, the current collecting shoe 7 cannot be inserted into the wiring space 21 and moved.

In this embodiment, the following closing body 5 is employed to close the slit 22.

As shown in FIG.
It is composed of a large number of plate pieces 51 that are arranged side by side on the same horizontal plane at the upper end of 2.

Each plate piece 51 is made of an elastic material or a hard material, and one end of each plate piece 51 is pivotally supported by pins so as to be openable and closable.

FIG. 4 shows another closing body 5 that closes the slit 22 by holding two elastic plate pieces 51 together.

In the closing body 5 shown in FIG. 4, one end of a plate piece 51 is fixed with a fixing pin 52 or the like, and the slit 22 can be opened and closed by utilizing the elasticity of the plate piece 51.

<H> Current collector shoes The current collector shoe 7 is shown in FIGS. 1 and 6.

The current collector shoe 7 is attached to the bottom of the train facing downward, and is composed of a narrow copper electric plate that slides into contact with the power line 4 in the wiring space 21, and a protrusion 8 is brought into contact with it in the running direction of the train. ing.

The protruding body 8 is a member for pushing open the closing body 5 before the current collecting shoe 7 to smoothly move the current collecting shoe 7, and has a substantially streamlined shape.

The protrusion 8 is formed with a push-up surface 81 having a downward slope in the running direction of the train.

Since this pushing-up surface 81 pushes open the closure body 5 and opens the slit 22, the contact resistance between the current collector shoe 7 and the closure body 5 becomes extremely small.

<Other Embodiments> As another means for pushing open the closure body 5 prior to passage of the collector shoe 7, it is also possible to use a rotary protrusion 9 as shown in FIG.

The disc-shaped protrusion 9 is rotatably attached to the tip of an arm 71 protruding from the current collector shoe 7.

The protrusion 9 rotates idly due to contact resistance with the closure body 5 without any special rotational drive means.

According to this embodiment, since the projection 9 rotates when pushing the closure 5 open, there is an advantage that the contact resistance with the closure 5 becomes smaller.

Further, in the above embodiment, the case of pushing up to open and close in the vertical direction has been described, but in the case of the closure body 5 that opens and closes in the horizontal direction, protrusions 8 and 9 may be provided on the circumferential surface of the current collector shoe 7. Deal with it.

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

(a) A protrusion attached integrally with the current collecting shoe on the traveling direction side of the current collecting shoe pushes the closing body upward in advance of the last current shoe, thereby reducing the contact resistance between the last current shoe and the closing body.

Therefore, it is possible to avoid abrasion and damage to the current collector shoe and the closure body, and it is also possible to significantly reduce the running resistance of the current collector shoe.

(b) By arranging the power lines in the wiring space below the tracks, there will be no wiring above the ground, resulting in a better view.
