By moving the train to and from the second branch position of the virtual line in the figure, the train route is switched.

In such a railway branch, there is a step that causes a running shock at the opposing ends of the branch track and the connecting tracks B and C running path D1゜B and C at both branch positions. It is necessary to connect them flush with each other.

On the other hand, since the movement locus of the tip of the branch track at the time of track switching is not constant due to changes in the length of the branch track due to changes in temperature, etc., it is necessary to prevent the ends of the running road from interfering with each other at the time of track switching.

Conventionally, the one shown in Fig. 6.7 is known as a connecting device for this travel path. The figure illustrates a state in which the branch track is set at the first branch position.

At the opposing ends of both tracks, running path D of B, and B1, recesses 1 and 2 are provided at two places on the left and right where train wheels (rubber tires) H pass, and a fixing plate 3 is provided in the recess 1 on the branch track side. , a movable plate 4 is provided in the concave portion 2 on the connecting track side, and the upper surface thereof has a running path D construction.

It is installed flush with Work B.

However, according to such a hydraulic cylinder-driven travel path connecting device, the hydraulic cylinder control well and its control device,
Since various equipment such as electrical wiring and hydraulic piping is required, the equipment cost is high, and maintenance is troublesome and expensive.

In addition, the more complex the structure, the more likely it is to fail, and the operation tends to become unstable due to oil leakage, changes in the viscosity of the cylinder hydraulic oil due to changes in temperature, etc., which are problems specific to hydraulic pressure.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a track connecting device for a railway branch, which can simplify the equipment with a simple configuration that does not use hydraulic pressure, and can improve operational stability.

[Means to solve the problem]

The present invention provides a railway branching section where a branch track is selectively connected to a plurality of connecting tracks to switch the course of a train by moving the branching track between a plurality of branching positions selectively connected to a plurality of connecting tracks. At the end of the track, there is a movable plate that can slide in the length direction of the track, and a spring force is exerted in the direction of protruding the movable plate from the end of the track and pressing it against the end of the track on the other track. On the other hand, a guide rail is provided in the running road width direction at the running road end of the other track, and the movable plate is provided with a guide rail in the running road width direction.
A guide member is provided in contact with the guide rail to restrict the amount of protrusion of the movable plate from the end of the travel path (claim 1).

Further, in the configuration of claim 1, the invention according to claim 2 provides an engagement between the movable plate and the opposing ends of the running path on the other track to irreleasably connect the two at each branch position of the branch track. It consists of a section.

[Effect]

According to this configuration, the movable plate is pressed against the end of the running path of the other track by the spring force, and the running paths are connected to each other. On the other hand, at the time of track switching, since the amount of protrusion of the movable plate is regulated by the guide rail and the guide member, interference between the movable plate and the running path end of the other track can be prevented.

In this way, by using spring force instead of hydraulic pressure as the driving force for connecting the travel path, no hydraulic equipment is required, and the configuration can be significantly simplified.

In addition, there is no risk of failure, and problems specific to hydraulic pressure such as oil leakage and changes in the viscosity of cylinder hydraulic oil are eliminated, and the stability of operation can be improved.
