DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, as a branching device of this kind,
As shown in JP-A-59-6763, a plurality of movable girders are arranged in the lengthwise direction of a track at a crossing portion of a double track fixed track and rotatable around a vertical axis at opposing ends. A joint trajectory configured by coupling is provided, and the joint trajectory is moved between a reference position connecting the up lines and down lines of the fixed track on both sides and a crossover position connecting the upper and lower different lines. Such a configuration is known.

[0003]

However, in this known branching device, the movable girder forming the joint trajectory is moved separately for the upper and lower lines when the trajectory is changed. A source (motor or cylinder) is required.

For this reason, (a) the entire equipment of the 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.

[0005] (b) As the number of equipments and pipes increases, important daily maintenance work on railways becomes troublesome, and maintenance costs increase.

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

Accordingly, the present invention simplifies the structure of a moving device for changing the track, realizes a reduction in various costs and simplifies maintenance, and can easily control the girder movement at the time of changing the railroad branching device. Is provided.

[0008]

The present invention has the following arrangement.

(A) A first connecting track connected to one of the fixed tracks on both sides and a second connecting track connected to the other of the fixed tracks on both sides of a double track fixed track comprising an up line and a down line. It should be arranged facing the track length direction.

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

(C) In the first and second connecting tracks, the corresponding vertical axes of the upper and lower lines are connected by a connecting link, and a plurality of parallel link mechanisms are connected between the upper and lower lines by the connecting link and the movable girder. Is configured.

(D) The first and second connecting tracks are
A moving device for changing the position between a reference position where the up lines and the down lines are connected to each other and a crossover position where the lines different from each other up and down are connected.

[0013]

According to the above arrangement, when the track is changed, the movable beams corresponding to the upper and lower lines in the first and second connecting tracks 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 between the upper and lower lines.

At the time of orbit change, troublesome control for keeping the vertical line spacing constant is unnecessary.

The fluid pressure cylinders 5 and 5 are mounted on the floor F with the rod ends connected to the base movable beams 1a and 1b of the descending lines C2 and D2. The proximal movable girder 1a, 1b is moved by the (expansion / contraction) operation.

On the other hand, the pulling mechanisms 6 include a motor (hydraulic motor or electric motor) 7 as a drive source and a chain 8 pulled by the motor 7, as shown in detail in FIGS. I have.

The motor 7 is installed on one of the right and left sides of the connecting tracks C and D on the floor F, and a driving sprocket 9 is mounted on a rotating shaft of the motor 7. On the other side on the floor F, the driven sprocket 1
0 is attached.

The chain 8 is passed between the driving and driven sprockets 9 and 10 below the connecting tracks C and D, and both ends of the chain 8 are fixed to the upper and lower movable beams 1a and 1b.

With this configuration, the forward / reverse rotational force of the motor 7 is transmitted through the connecting tracks C,
D is transmitted to the movable beams 1a and 1b of the upper and lower lines as moving force.

Therefore, by rotating the motor 7 in the opposite directions in the two connecting tracks C and D, the two connecting tracks C and D
Can be moved between the reference position in FIGS. 1, 3 and 5 and the crossover position in FIG. 2 and FIG. 4 (or the crossover position on the opposite side).

While the carriage 3 moves on the carriage rail 4 in a direction perpendicular to the track, the movable girders 1a and 1b move while being deformed in a folded line by joint motion. Therefore, as shown in FIG. 5, between the movable girders 1a and 1b and the bogie 3,
Sliding support 1 for enabling these relative horizontal movements

Are provided integrally, and the latch 23 provided on the floor surface F side is driven by the cylinder 24 in a state where the connecting tracks C and D are set at the crossover position (the state where the bracket 21 is in contact with the stopper 22). It is hooked on the hook 21a. Thereby, the connection tracks C and D are locked at the crossover position.

When the moving amount of the movable girder is large, the pulling mechanism 6 may be used in place of the hydraulic cylinder 5 as in the case of other movable girder.

Further, in the above embodiment, in order to further simplify the structure of the moving device, the structure in which the pulling mechanism 6 can be used for bidirectional movement between the reference position and the crossover position of the connecting tracks C and D is used. However, a configuration in which the movement in both directions is performed by separate pulling mechanisms may be adopted.

As described above, according to the present invention, the corresponding vertical axes of the upper and lower lines of the first and second connecting tracks provided at the transition portion of the double track fixed track are connected by connecting links. A plurality of parallel link mechanisms between the upper and lower lines, and at the time of orbit change between the reference position and the crossover position, the parallel movement of this parallel link mechanism integrally and parallelly moves the corresponding movable girder of the upper and lower lines. Since the moving device is configured to be moved in the state, the driving source and the driving mechanism of the moving device for moving the connecting track are common to the upper and lower lines.

For this reason, in comparison with a conventionally known device for moving the movable girder separately in the upper and lower lines, (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 piping is provided. It can be simplified, and equipment and construction costs are much lower.

(B) The equipment and piping are greatly reduced, so that daily maintenance is easy and the maintenance cost can be reduced.

(C) Since special control for keeping the interval between the upper and lower lines constant before and after the change is not required, the control of the position and speed of each movable girder for that purpose becomes very easy, and the orbit change operation can be performed. It can be done quickly and accurately.
