[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instantaneous snow removing device for removing a snow block caught between movable portions of a switch (hereinafter referred to as "point") for switching a railroad track.

[0002]

2. Description of the Related Art When there is snowfall in a snowy country or the like, it can be seen that a running train runs with snow and ice rolled downward. A train often drops snow and ice trapped around the bottom of the train due to vibrations when traveling at the joints of rails at points.

[0003] This is so-called "falling snow" and causes a malfunction of a point. For example, when falling snow falls on the movable part of the point, the rail may not switch between the movable parts. As a device for removing the snowfall, there is a snow melting device that injects hot water preheated by a boiler to a rail to melt snow. In Japanese Patent Application Laid-Open No. 6-240606, a piping unit is attached to a tong rail, and a nozzle provided in the piping unit is used.
BACKGROUND ART A snow removing device that removes snow by injecting air is disclosed.

However, in the above-mentioned conventional snow melting apparatus using hot water, even the smallest type used in a conventional line needs to use about 40 liters of hot water, and is used in a Shinkansen. As a type, it is necessary to use several hundred liters of warm water. Further, in a conventional snow melting apparatus using hot water, it is necessary to use hot water, so that it is necessary to warm the water with a boiler. For this reason, the conventional line costs several million yen, the Shinkansen costs tens of millions of yen, and the initial cost and the running cost are high.

Further, the snow removing device disclosed in Japanese Patent Application Laid-Open No. 6-240606 removes snow only by the pressure of air, and therefore has a low ability to remove snow. In order to increase the removal capacity, it is necessary to arrange a nozzle near the object to be removed,
It will be necessary to install a nozzle for each sleeper. For this reason, in the snow removal apparatus disclosed in Japanese Patent Application Laid-Open No. 7-54317, a plurality of nozzles are provided by drilling holes in the rails to enhance the removal ability. However, it is necessary to make a hole in the rail and attach a nozzle, and it is necessary to provide a plurality of nozzles in order to further enhance the removal capability. Therefore, there has been a problem that skeleton work is difficult and initial cost is high.

The present invention has been made in view of the above-mentioned problem, and is an inexpensive method that can remove a snow lump caught between movable portions of a branching point with a small amount of liquid and / or compressed gas.

In the above description, the instantaneous snow removing device 21 is installed immediately before switching from the main rail 11 to the tong rail 12, but water and / or water is directed toward the snow mass 14 sandwiched between the movable parts 10 at the points. Other locations may be used as long as compressed air can be emitted. Further, the instantaneous snow removal device 21 can be applied to other movable parts such as a crossing part. In this way, a snow lump sandwiched between other movable parts such as the crossing part can be melted, crushed, or blown off and removed.

Further, in the above description, two of the instantaneous snow removal devices 21 and 21 'of the branching device are installed on the main rails 11 and 11'. However, even if only one is installed on the main rail 11 or 11 ', they are mounted. The object of removing the snow clump 14 sandwiched between the movable parts 10 on the rail 11 or 11 'can be achieved.

Further, in the above, the eccentric nozzle 3
3, the air chamber 31 and the water chamber 32 are integrally configured, but the eccentric nozzle 33 and the air chamber 31 and the water chamber 32 are configured separately, and only the eccentric nozzle 33 is installed near the movable part. The air chamber 31 and the water chamber 32 may be connected to each other by a piping material such as a hose, and the air chamber 31 and the water chamber 32 may be installed in a place different from the eccentric nozzle 33. For example, only the eccentric nozzle 33 may be attached to the main rail 11 just before switching from the main rail 11 to the tong rail 12 toward the tong rail 12, and the air chamber 31 and the water chamber 32 may be installed at another place.

Further, in the above, air was supplied and stored in the air chamber 31. However, other than air, any gas that can be safely compressed and released in a general environment may be used.

Further, in the above, water mixed with antifreeze is used. However, if all antifreeze is used, freezing of water can be completely prevented. Further, water mixed with a snow melting agent may be used. In this way, the snow lump 1 sandwiched between the movable parts 10
4 can promote melting of snow and ice.
Further, a liquid other than water may be used.

Further, in the above, a means for heating water may be provided, and the snow mass 14 may be melted or blown off using hot water to be removed.

Further, in the above, the remote control 51
Of the instantaneous snow removal device 21 by the sequencer 51
Is electrically performed through the solenoid valves 61, 62, and 63, however, a pneumatic valve may be provided instead of the solenoid valves 61, 62, and 63, and the pneumatic operation may be performed by the sequencer 51 through the pneumatic valve. Good.
