Description

[Detailed Description of the Invention] This invention relates to an improvement of a branching device for railway rails.

general! As shown in Fig. 4, the trackless rail is a large number of sleepers 1.1 arranged on the ground at appropriate intervals, and is necessary for laying basic rails 3 parallel to each other with floor plates 2 interposed between them. A lead rail 4 branching from this basic rail 3 is laid according to the above, and one end thereof is connected to the lead rail 4 at the branching part between these basic rails 3 and lead rail 4,
Tongue rail 5 whose other end selectively connects to the basic rail 3
It is arranged.

In this case, the connection state of the branch part is the tongue rail 5.
The gap between the tongue rail 5 and the basic rail 3 within 500mm from the free end of the tongue rail 5 must be within 0.5rIrIIL, and within 50owIt from the free end, the gap between the tongue rail 5 and the basic rail 3 must be completely adhered even under a pressure of 100kg. It is said that

However, in the conventional branching device, as shown in FIG. The other end of the connecting member 9, one end of which is fixed by a fixing device 8 such as a port or nut, is made to stand up in an inclined manner toward the inner surface, which is the surface on which the tongue rail 5 is attached, to connect the port or nut. Since they are connected by the tool 10, there is a risk that a gap a may be created between the basic rail 3 and the tongue rail 5 when pressurized by the passage of a vehicle (not shown).

This is because the fixing portion of the connecting member 9 is located at a lower position than the connecting portion of the tongue rail 5, and thus the tongue rail 5 is caused to bend slightly due to the rotational moment due to the pressurizing force.

Therefore, as mentioned above, the gap between the basic rail 3 and the tongue rail 5 not only causes problems for the wheels A of passing vehicles, but also causes the gap to become large due to the repeated small turning phenomenon, causing the basic rail to become damaged. 3, the tongue rail 5, or other connecting parts may be damaged, resulting in a shortened lifespan, and there is also a risk that an unexpected accident may occur, and there is currently a need for improvement.

This invention was made with the intention of solving the above problem, and the connection between the point bar and the tongue rail is extended almost horizontally from the point where the point of attachment that stands up on the point is extended. Provided is a railway rail branching device characterized in that the gap between the basic rail and the tongue rail is reduced as much as possible by connecting the tongue rail at approximately the central position in the height direction of the tongue rail via a connecting member. This is what I am trying to do.

This invention will be explained below based on FIGS. 1 to 3. The tongue rail 5 and the part attached to the point adjacent to the tongue rail 5 on the point rod disposed on the lower surface of the basic rail 3 are 11 stands up and opens in a U-shape toward the tongue rail 5. This mounting has a recess 11'.
The other end of the approximately T-shaped connecting member 13, whose one end is fixed by a fixing member 12 such as a bolt or nut, is attached to the surface 13'.
is in contact with the inner surface of the tongue rail 5, and the tongue rail 5 and the connecting member 13 are attached at approximately the center position in the height direction of the tongue rail 5. The tongue rail 5 and the switching rod 6 that controls the selection operation of the tongue rail 5 are connected at approximately the center position of the tongue rail 5 in the height direction.

In this case, the connecting member 13 is attached on the surface 13', and the connecting member 13 extending horizontally is provided with an elongated hole 15, and the connecting tool 14 penetrates into this elongated hole 15 and connects the tongue rail 5. In connection, the tongue rail 5 and the point rod 6 can be connected in an adjustable manner.

This is because the lengths of the tongue rails 5 are not necessarily equal on the left and right sides due to acceleration due to passing vehicles and manufacturing tolerances, so unreasonable force is applied to the adjustment of the branch part and the work takes a long time. This is advantageous in that it solves the problem.

That is, by adjustingably connecting the tongue rail 5 and the rolling pin 6, the above-mentioned error can be eliminated and the working time can be shortened.

As explained above, according to the branching device of this invention,
The tongue rail and the switch rod that controls the selection operation of the tongue rail are mounted on the switch rod in the height direction of the tongue rail through a connecting member extending almost horizontally from the top. Since the basic rail and the tongue rail are connected at approximately the center position, no rotation moment is generated in the tongue rail even when a load is applied due to the passing of a vehicle, and no gap is generated between the base rail and the tongue rail.

Therefore, the service life of the branching device can be increased, there is no risk of causing trouble to the vehicle, and there are excellent effects such as being able to prevent unexpected accidents from occurring.

Furthermore, in the branching device of this invention, the tongue rail of the connecting member is attached by providing an elongated hole extending horizontally in the surface, thereby eliminating functional and manufacturing tolerances that the tongue rail inevitably has. Since it can be easily installed and taken into consideration, its utility value is remarkable.

Claims (1)

[Claims for Utility Model Registration] 1. In a device in which a tongue rail is selectively connected to a basic rail at a branching part of a railway rail, there is no attachment on a point rod that controls the selection operation of the tongue rail. This is done by connecting the tip and the inner surface of the tongue rail through a substantially T-shaped connecting member extending in a substantially horizontal direction, thereby connecting the tip rod and the tongue rail to the tongue rail. A railway rail branching device that connects and cuts at approximately the center position of the rails in the height direction. 2. To attach the tongue rail of the connecting member, provide an elongated hole for attachment extending horizontally in the section, and when connecting with a connecting tool that passes through this elongated hole and connects the tongue rail, the tongue rail and the tongue rail are connected. 2. A railway rail branching device according to claim 1, wherein the two rods are adjustable and connected to each other.
