Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a branching device instantaneous snow removal device for removing a snow mass sandwiched between movable parts of a branching device (hereinafter referred to as “point”) for switching a railroad track.
[0002]
[Prior art]
When there is a snowfall, such as in a snowy country, you can see that the running train runs under snow and ice. Trains vibrate as they travel along the rail joints at points, and often drop snow and ice squeezed under the train.
[0003]
This is so-called “falling snow” and causes a point malfunction. For example, when snow falls on a movable part of a point, the rail may not be switched between the movable parts. As a means for removing this snow fall, there is a snow melting device that melts snow by injecting hot water previously warmed by a boiler onto a rail. Japanese Patent Application Laid-Open No. 6-240606 discloses a snow removal device that removes snow by attaching a piping unit to a tongrel and injecting air from a nozzle provided in the piping unit.
[0004]
[Problems to be solved by the invention]
However, in the conventional snow melting apparatus using hot water, it is necessary to use about 40 liters of hot water as the type used in the conventional line, and several hundred liters of hot water is used as the type used in the Shinkansen. Must be used. Moreover, since it is necessary to use warm water in the conventional snow melting apparatus using warm water, it is necessary to warm water with a boiler. For this reason, the conventional line costs several million yen, and the Shinkansen costs tens of million yen, and there is a problem that the initial cost and running cost are high.
[0005]
Further, the snow removal device disclosed in Japanese Patent Laid-Open No. 6-240606 has a low removal capability because it removes snow only by air pressure. In order to increase the removal capability, it is necessary to dispose the nozzle near the removal object, and it is necessary to install the nozzle for each sleeper. For this reason, in the snow removal device disclosed in Japanese Patent Application Laid-Open No. 7-54317, a plurality of nozzles are attached by making holes in the rail to enhance the removal capability. However, since it is necessary to make holes in the rails and attach the nozzles, and it is necessary to provide a plurality of nozzles in order to enhance the removal capability, there has been a problem that the housing construction is difficult and the initial cost is high.
[0006]
The present invention has been made in view of the above-described problems, and is an inexpensive branching moment that can remove a snow mass sandwiched between movable parts of a branching unit (point) with a small amount of liquid and / or compressed gas.

The partition wall 35 separates the water chamber 32 and the eccentric nozzle 33 and is a rubber film having a cut. The partition wall 35 can be omitted by devising the mechanism of the eccentric nozzle 33.
[0024]
The branching device instantaneous snow removal device 21 configured as described above is connected to the remote control unit 41 as described above. The remote operation unit 41 includes a sequencer 51 for sequence control, an air supply source 52 for supplying air to the air chamber 31, and a water supply source 53 for supplying water to the water chamber 32.

Can be. Moreover, since the branching device instantaneous snow removal apparatus 21 of this Embodiment only needs to be attached to this rail 11, there is no need for frame construction and cost can be reduced.
[0037]
In the above description, the branching device instantaneous snow removal device 21 is installed immediately before switching from the main rail 11 to the Tongrel 12, but water and / or compressed air is directed toward the snow mass 14 sandwiched between the movable parts 10 at the point. Other locations are acceptable as long as they can be fired. Moreover, it is also possible to apply the branching device instantaneous snow removal device 21 to other movable parts such as a crossing section. If it does in this way, the snow mass pinched | interposed into other movable parts, such as a crossing part, can be melt | dissolved, grind | pulverized, or can be blown away and removed.

For example, only the eccentric nozzle 33 may be attached to the main rail 11 immediately before switching from the main rail 11 to the Tongrel 12 toward the Tongrel 12 and the air chamber 31 and the water chamber 32 may be installed in different places.
[0040]
Furthermore, in the above description, air is supplied to and stored in the air chamber 31. However, any gas other than air may be used as long as it can be safely compressed and released in a general environment.
[0041]
Furthermore, in the above, water mixed with antifreeze is used, but if all antifreeze is used, freezing of water can be completely prevented. Alternatively, water mixed with a snow melting agent may be used. In this way, melting of snow and ice contained in the snow mass 14 sandwiched between the movable parts 10 can be promoted. Furthermore, liquids other than water may be used.
