[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branching device used in a crossover portion (upper and lower line connecting portion) in a double-track type magnetic levitation railway.

[0002]

2. Description of the Related Art Conventionally, as this type of branching device for migration,
As shown in Japanese Patent Laid-Open No. 59-6763, a plurality of movable girders are arranged in the track length direction in the cross section of a fixed track of a double track, and the movable girders are rotatable about a vertical axis at opposite ends. A joint trajectory formed by connecting is provided, and the joint trajectory is moved between a reference position for connecting the upward lines and the downward lines of the fixed tracks on both sides and a crossing position for connecting the lines that are vertically different from each other. This is well known.

However, in this known branching device, since the movable girders constituting the joint orbital are moved separately in the vertical line when the orbit is changed, many driving devices are used for the moving device for this girder movement. A source (motor or cylinder) is required.

Therefore, (a) the equipment of the entire moving apparatus including the mechanism for transmitting the driving force of the driving source to the movable girder and the hydraulic piping becomes large and complicated, and the equipment cost and the construction cost are high.

(B) The increase in the number of equipments and pipes complicates the daily maintenance that is important in railways, and the maintenance cost becomes high.

(C) Since the distance between the upper and lower lines must be kept constant before and after the conversion, it is very troublesome to control the position and speed of each movable girder for that purpose.

In view of this, the present invention simplifies the structure of a moving device for changing rails, realizes a reduction in various costs and simplification of maintenance, and a railway branching device that facilitates girder movement control during conversion. Is provided.

[0008]

The present invention has the following configuration.

(A) A first connecting track connected to one of the fixed tracks on both sides and a second connecting track connected to the other are provided at the crossing portion of a double track type fixed track consisting of an up line and a down line. Must be arranged facing each other in the track length direction.

(B) The first and second connecting tracks are
A plurality of movable girders, which are respectively mounted on the trolley and arranged in the track length direction, are connected to each other at opposite ends so as to be rotatable about a vertical axis.

(C) In both the first and second connecting tracks, the vertical shafts corresponding to the upper and lower lines are connected by connecting links, and the connecting links and the movable girders provide a plurality of parallel link mechanisms between the upper and lower lines. Is configured.

(D) The above-mentioned first and second connecting tracks,
A moving device that shifts the position between a reference position where the upward lines and the downward lines are connected to each other and a transition position where the lines different from each other in the vertical direction are connected.

[0013]

According to the above construction, when the orbit is changed, the movable girders corresponding to the upper and lower lines of the first and second connecting orbits move integrally and in parallel by the parallel movement of the parallel link mechanism. For this reason, the drive source and drive mechanism of the moving device for moving the connecting track can be shared by the upper and lower lines.

At the time of changing the orbit, it is not necessary to perform a troublesome control for keeping the vertical line spacing constant.

As described above, according to the present invention, the vertical shafts corresponding to the upper and lower lines of the first and second connecting tracks provided on the connecting portion of the double-track fixed track are connected by the connecting link. By configuring a plurality of parallel link mechanisms between the upper and lower lines, when the orbit is changed between the reference position and the crossing position, the parallel movement of the parallel link mechanism causes the movable girders corresponding to the upper and lower lines to be integrated and parallel. Since it is configured to move in the state, the drive source and the drive mechanism of the moving device for moving the connecting track can be common to the upper and lower lines.

Therefore, as compared with a conventionally known device that moves the movable girder separately in the vertical direction, (a) the equipment of the entire moving device including the mechanism for transmitting the driving force of the drive source to the movable girder and the hydraulic pipe is installed. It can be simplified and the equipment cost and construction cost are much cheaper.

(B) By greatly reducing the number of equipment and pipes, daily maintenance becomes easy and maintenance costs can be reduced.

(C) Since no special control is required to keep the distance between the upper and lower lines constant before and after the conversion, it is very easy to control the position and speed of each movable girder for that purpose, and the orbit conversion operation can be performed. It is possible to do it quickly and accurately.
