DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing foreign matter at a track branching point which removes foreign matter which has fallen between a basic rail and a tongue rail at a railroad branching point in a railway in a snowfall area by air injection. is there.

[0002]

2. Description of the Related Art An electric heating type, a hot air type, a hot water type or the like is installed in a turnout of a railway track in a snowfall area. Electric heaters have heaters and heater panels installed between rails or sleepers to melt snow. In the hot air type, hot air generated by a hot air generator such as a boiler is blown out from a blowout port attached around a branch via a duct to melt snow. In the hot water type, hot water is sprinkled with a sprinkler to melt snow. These snow-melting devices exhibit a snow-melting effect against snowfall or snow brought in by bringing snow accumulated on a track portion by a snow plow attached to the leading end of a tracked vehicle.

[0003] However, falling snow and ice dropped by the vibration of the vehicle when passing through the track branch, or flying stones generated by the ballast jumping when the falling snow and ice fall on the ballast, are caused by the basic rail of the track branch. When it is sandwiched between the tongue rail and the tongue rail, the tongue rail is not converted. According to the snow melting device, in the case of falling snow and ice, it will melt if there is some time to spare,
If it is necessary to change points in a short time after passing the vehicle, it may cause a change. In addition, stepping stones cannot be melted and must be removed by some method. Since the tong rail is moved on the floor board on the sleeper and turns, if the stepping stone falls on the floor board between the basic rail and the tongue rail, it causes non-conversion. Conventionally, when such a situation occurs, an attendant rushes to the site to remove the situation.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a foreign matter removing device capable of removing foreign matter between a basic rail and a tong rail so that a turnout device cannot be disabled by falling snow and ice or flying stones. It is assumed that.

[0005]

According to the present invention, there is provided an apparatus for removing foreign matter at a track branching portion for removing foreign matter falling between a basic rail and a tongue rail of a track branching portion. A piping unit is mounted on the opposing side surface of the basic rail or tong rail according to the length of the branch track, and a plurality of nozzles having an opening in the tip direction of the tong rail are provided along the track on this piping unit, and An air source device having an air compressor and an air reservoir is installed in the vicinity, an air reservoir of the air source device is connected to the piping unit, and communication between the air reservoir and the piping unit is disconnected from the air source device. A switching means is provided.

[0006]

When compressed air is sent from the air reservoir to the piping unit side by the switching means, the compressed air is jetted from the nozzle to generate an air flow between the basic rail or the tongue rail toward the tip of the tongue rail. As a result, foreign matter between the basic rail and the tongue rail is blown off and removed.

The thus configured first and second embodiments of the foreign matter removing device at the track branching section include, for example, a signal from a properly provided foreign matter drop detection switch, a point switching signal, and a signal from a snowfall sensor. The electromagnetic switching valve 6 is switched from the shut-off state by an electromagnetic switching valve operation signal utilizing the above-described method, and compressed air from the compressed air reservoir 20 is supplied to the piping units 1 and 2 on the side where the tongue rail 8 is separated from the basic rail 7. Then, air is injected from the nozzles 3 and 4 for several seconds (controlled by a timer) to blow off and remove foreign substances such as falling snow and ice and flying stones.

When the foreign matter on the floor plate 9 is a flying stone, the size is small, and the purpose can be achieved by moving the foreign matter on the ballast. However, if the falling snow and ice are large, even if the snow and ice are moved to the ballast position, there is a possibility that the switching of points may become an obstacle. Therefore, more preferably, as shown in FIG.
Should be provided. FIG. 6 shows an installation state of the flat plate 27. FIG. 7 shows an installation state of another flat plate 27a.
When such a flat plate 27 or 27a is provided, the ballast portion is covered and the upper surface becomes smooth, and foreign matter is easily moved by the blast air. It is pushed out to the tip side.

As described above, foreign matters such as flying stones and falling snow and ice falling between the basic rail and the tongue rail can be reliably removed, so that the inability to change points due to the foreign matters can be eliminated. In addition, this device has the advantage that it can be easily installed by drilling holes for mounting piping units on the rails and requires little modification of the track, and there is almost no interference with existing snow melting equipment from the installed state. is there.

In the above-described embodiment, the description has been given of the case where the foreign matter is simply blown off. However, in some cases, a heating means for heating at a stage before the air is blown out may be provided to blow the hot air. In addition, the piping unit provided with the nozzle described above is used for hot water injection or hot air injection of the snow melting device, and is used for concentrated snow melting between the basic rail and the tongue rail which is the most important point where the point cannot be changed. You may.

[0017]

According to the present invention, high-pressure injection is possible because compressed air is used, and foreign matter such as snow and ice and flying stones between the basic rail and the tongue rail can be reliably and instantaneously removed. The problem of being unable to switch can be solved.
Further, since the apparatus of the present invention uses compressed air, there is no possibility of freezing after the operation as in the water spray type snow melting apparatus.
