Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail track structure, and more particularly to a rail track structure used for a lightweight machine such as a truck.

[0002]

[Prior art]

 In general, the truck that is used when discharging excavated soil from the bottom of an inclined shaft uses a lightweight and simple rail track that is different from ordinary railroad tracks.

In this type of rail track system, wheels with flanges run on the rails as in ordinary railroads, but at corners with a small radius, wheels are removed from the rails due to centrifugal force or the like. There is a risk of This tendency is particularly strong when the locomotive pushes the trolley loaded with earth and sand from the rear.

In order to prevent this, in a general railroad, a wheel guard rail and a guide for preventing wheel derailment are arranged along the main rail positioned inside to stabilize the running of the wheels and prevent safety. You may try to secure it.

[0005]

[Problems to be solved by the device]

 However, in the rail track of the standard used for trucks, the wheel is relatively small and the flange width of the wheel is narrow, so the distance between the main rail and the wheel guard rail must be narrowed. However, doing so causes the lower parts of the rails to come close to each other, and there is a problem in that it is no longer possible to secure a space for striking the sleepers to fix the rails.

On the other hand, if the distance between the main rail and the wheel guard rail is made large enough to strike the spike, the important wheel guard effect cannot be expected. In addition, it is disadvantageous in terms of cost and labor to use a special guide as a measure for preventing derailment on a temporary track.

Further, there is also a problem that the weight of the vehicle to which the centrifugal force is applied is applied to the wheel guard rail, which causes the wheel rail to be deformed. Therefore, wheel guard rails must be fixedly fixed to the main rail at regular intervals to withstand a considerable load.

The present invention has been made in view of the above matters, and provides a rail track structure capable of easily, reliably, and robustly mounting a wheel guard rail even on a light rail track for a truck. This is a technical issue.

[0009]

[Means for Solving the Problems]

 In order to solve the above technical problems, the present invention has the following structure in a rail track structure in which a wheel guard rail 2 is arranged in parallel with a main rail 1.

That is, perforated portions 5 and 6 are formed on the side wall surfaces 3 and 4 of the main rail 1 and the wheel guard rail 2, respectively, and the perforated portions 5 and 6 are bridged with a connecting body 7 and the perforated portions are formed. Fixing tools 8 are respectively screwed into the connecting bodies 7 from the parts 5 and 6 to integrally fix the main rail 1 and the wheel guard rails 2, and the outer edge 9 of each of the main rail 1 and the wheel guard rail 2 is fixed. Fixing 10 to the sleeper 11 is a technical means.

The sleeper 11 is, of course, a concept including PC concrete and metal other than wood.

[0012]

[Action]

 Since the main line rail 1 and the wheel guard rail 2 are integrated by the connecting body 7 and the fixture 8, the outer edges 9, 10 of the main line rail 1 and the wheel guard rail 2 are simply attached to the sleeper 11. , It is possible to easily and reliably install wheel guard rails at regular intervals on the curved part of the track.

Further, since the main line rail 1 and the wheel guard rail 2 are integrated via the connecting body 7, the strength of the rail is increased and the structure is less likely to be deformed.

[0014]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a plan view, in which two curved main rails 1 are laid, and a wheel guard rail 2 is arranged in parallel with the main rail 1 which is located in the internal rule.

The cross sections of the main rail 1 and the wheel guard rail 2 each have a shape in which “H” is laid sideways, and upper and lower horizontal portions are connected by a side wall surface 3 (4). . The side wall surfaces 3 and 4 of the main rail 1 and the wheel guard rail 2 are provided with perforated portions 5 and 6 at regular intervals.

The connecting body 7 bridges between the perforated portions 5 and 6. This connecting body is an iron pipe with an outer diameter of 25 mm, and its length is such that the flange 13 of the vehicle wheel 12 has a margin between the main rail 1 and the wheel guard rail 2 and rattling more than necessary. Set it so that it fits in. In the embodiment, the interval is set such that the main rail 1 and the wheel guard rail 2 come into contact with each other.

The connecting body 7 has a thread formed on both inner ends thereof so that a bolt can be screwed therein. With the connecting body 7 installed in the perforated portions 5 and 6, the fixture 8 is screwed into the connected body 7 through the perforated portions 5 and 6, respectively. A bolt is used for the fixture 8, and the main rail 1 and the wheel guard rail 2 are integrally fixed by fixing the bolt. In this state, the outer edges 9 and 10 of the main rail 1 and the wheel guard rail 2 are fixed to the sleeper 11. In the embodiment shown in FIG. 2, H steel is used as the sleeper 11, and the outer edges 9 and 10 are fixed to the sleeper 11 by welding 14 and 15.

FIG. 3 shows another embodiment, which is different from the above-described embodiment in the method of fixing the outer edges 9 and 10 to the sleepers 11. That is, in this embodiment, the outer edges 9 and 10 are fixed to the sleepers 11 by a spike. As a method of fixing the outer edges 9 and 10 to the sleeper 11, a method of fixing the outer edges 9 and 10 by making the sleeper 11 of concrete and driving a decker pin is considered.

With the above-described structure, the main rail 1 and the guard rail 2 are integrated by the connecting body 7 and the fixture 8, so that the outer edges of the main rail 1 and the guard rail 2 are separated from each other. It can be easily installed by simply attaching 9 and 10 to the sleeper 11. The distance between the main rail 1 and the wheel guard rail 2 can be arbitrarily set depending on the length of the connecting body 7, and it is easy to set the most effective distance. In addition, it was possible to secure sufficient strength for trucks and prevent derailment and deformation of the main rail.

[0020]

[Effect of device]

 According to the present invention, the main rail and the wheel guard rail are integrated by the connecting body and the fixture, and the outer edges of the main rail and the wheel guard rail are attached to the sleepers, so that the rail for the truck is lightweight. It is possible to mount the wheel guard rail easily and securely and firmly on the track.
