[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foreign matter removing device for a track branching portion, which removes foreign matter falling between a basic rail and a tongue rail of a track branching portion of a railway mainly in a snowfall region by air injection. is there.

[0002]

2. Description of the Related Art A snow melting device of an electric heating type, a hot air type, a hot water type or the like is installed on a branching device of a railroad track in a snowfall region. The electric type has a heater and a heater panel 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 through a duct from a blowout port attached to the vicinity of a branch to melt snow. The warm water type is designed to sprinkle warm water with a sprinkler to melt snow. These snow-melting devices exhibit a snow-melting effect against snowfall or bring-in snow caused by bringing in snow accumulated on the track portion by a snow plow attached to the leading end of the track vehicle.

[0003] However, falling snow and ice dropped by vibration when a vehicle passes through a track branching portion, or flying stones generated by jumping of the ballast when the falling snow ice falls on a ballast, are the basic rails of the track branching portion. If it is sandwiched between the tongle rail and the ton gray rail, inversion of the ton gray rail occurs. According to the snow melting device, in the case of falling snow and ice, it will melt if there is time to some extent,
When it is necessary to switch the points within a short time after passing the vehicle, it causes a non-conversion. Also, in the case of stepping stones, it cannot be melted, so it must be removed by some method. Since the tongue rail is moved on the floor board on the sleeper to be converted, if the stepping stone falls on the floor board between the basic rail and the tongue rail, it causes the inversion. In the past, when such a situation occurred, a staff member rushed to the site to remove it.

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 tongue rail so that a branching device cannot be converted by falling snow and ice or flying stones. It is what

[0005]

The foreign matter removing device for a track branching portion of the present invention is a foreign matter removing device for a track branching portion for removing a foreign matter that has fallen between a basic rail of a track branching portion and a tongue rail. Install a piping unit that is supplied with compressed air to the multiple sleepers laid under the basic rail and the tongue rail, and in the position facing the gap between the basic rail and the tongue rail of this piping unit, in the direction of the tongue rail tip. A nozzle having an opening is provided, an air compressor and an air source device having an air reservoir are installed in the vicinity of the orbit branching portion, the air reservoir of the air source device is connected to the piping unit, and the air source device is connected to the air source. It is characterized in that a switching means for disconnecting communication between the reservoir and the piping unit 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 and the tongue rail toward the tip end side of the tongue rail. The foreign matter between the basic rail and the tongue rail is blown away and removed.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. 1 (a) and FIGS. The foreign matter removing device at the orbital branch portion includes a piping unit 1, a nozzle 3, an air source device 5, and an electromagnetic switching valve 6.
Etc. In the figure, 7 is a basic rail, 8 is a tongue rail, and 9 is a floor board.

As shown in FIGS. 2A to 2C, the piping unit 1 has one end 11 of a square pipe 10 having a slightly flat cross section.
And the air supply pipe coupling portion 12 is provided at the other end, and the nozzle connection ports 13 are bored in one side of the narrow width of the square pipe 10 at appropriate intervals in the longitudinal direction. The plate member having the bolt holes 14a formed as the attachment portion 14 for the sleeper is welded to the lower surface of the. The length of the piping unit 1 is long enough to include the maximum width dimension when the tip of the tongue rail 8 opens and closes with respect to the basic rail 7.

As shown in FIGS. 2 (a) to 2 (c), the nozzle 3 has, for example, three small holes 16 obliquely formed in a plate 15 mounted so as to cover each nozzle connection port 13 of the piping unit 1. It was set up. The direction of the small hole 16 is an angle which is slightly obliquely upward with respect to the horizontal direction in a plane perpendicular to the square pipe 1. In the figure, 17 is a mounting screw and 18 is a packing. The intervals, number, angles, etc. of the small holes 16 are appropriately determined according to the situation.

As shown in FIG. 4, the air source device 5 has an air compressor 19, a compressed air reservoir 20 and their accessories, and the compressed air reservoir 20 serves as a switching means and an electromagnetic switching valve 6 and Two sets consisting of five pipe units 1 and 1a via pipes 23 and 24 (positioning side and opposite side)
Connected to the one. The electromagnetic switching valve 6 switches and connects the compressed air reservoir 20 to either one of the two sets of the piping units 1 and 1a by a predetermined electric signal.

FIG. 3 is a plan view of a track branching portion showing a schematic structure provided with the foreign matter removing device of this embodiment. Piping 2
3 and 24 are buried in the ballast. Piping unit 1, 1
Reference characters a are provided on the sleepers 26 in correspondence with the gaps formed by the basic rail 7 and the tongue rail 8 on the side opposite to the point and the localization side. The mounting state of the piping unit 1 on the rail is as shown in FIG. That is, each sleeper 2
The tongue rail 8 is attached to the upper surface of the nozzle 6 on the side with the tip thereof, and the air injection direction of the nozzle 3 is indicated by an arrow 21. The mounting is performed by bolts using the mounting holes 14a of the mounting portion 14 shown in FIG. In this embodiment, the floor plate 9 has a thickness of 15 mm, and the piping unit 1 is formed and installed so as to be within this size range. The tongue rail 8 is switched by the point switching device and moves on the floor plate 9. Since both the tongue rails 8 are connected at a constant interval near the tip by a rolling rod (the rolling rod position is indicated by 25 in FIG. 3) and are driven and moved in that state, one of the tongue rails 8 is moved. When opened, the other tongue rail 8 is closed. In FIG. 3, the arrow 21 indicates the ejection direction of the air ejected from the nozzle 3.

A second embodiment is shown in FIG. 1 (b). The difference of this embodiment from the first embodiment is that the nozzle connection port 13 provided in the piping unit 2 is provided on the wide surface of the flat square pipe 1, and details thereof are not shown. However, the same applies in that the nozzle 3 having the air ejection port formed in the plate is attached via the packing 18. The piping unit 2 is attached to the upper end of the front surface (the surface on the tip end side of the tongue rail 8) of each sleeper 26 as shown in the figure, and the direction of air injection by the nozzle 3 is indicated by an arrow 22.

A third embodiment is shown in FIG. 1 (c). This embodiment is different only in that the piping unit 2 of the second embodiment is attached to the sleeper 26 in that a recess 30 is provided at the upper end of the front surface of the sleeper 26 and is attached to the recess. The arrow 22 in the figure is the air injection direction. Since the other points of the second and third embodiments are the same as those of the first embodiment, the illustration and description thereof will be omitted.

The foreign matter removing devices for the track branching portions of the first, second, and third embodiments configured as described above include, for example, a signal of a foreign matter drop detection switch, a point switching signal, and a snowfall sensor that are appropriately provided. The electromagnetic switching valve 6 is switched from the closed state by the electromagnetic switching valve operation signal using a signal from the like, and the set of the piping unit 1 or the set of the piping unit 2 on the side where the tongue rail 8 is separated from the basic rail 7 The compressed air from the compressed air reservoir 20 is supplied to the nozzle, the air is jetted from the nozzle 3 for several seconds (controlled by a timer), and foreign substances such as falling snow and ice and flying stones are blown off and removed.

When the foreign matter on the floor plate 9 is a flying stone, the size is small, and therefore the purpose can be achieved by moving the foreign matter on the ballast. However, if there is a large amount of falling snow and ice, it may be an obstacle to point switching even if it is moved to the ballast position. Therefore, more preferably, as shown in FIG. 3, the flat plate 27 is placed between the sleepers 26 at a position indicated by an imaginary line.
Should be provided. FIG. 5 shows the installation state of the flat plate 27. If such a flat plate 27 is provided, the ballast portion is covered and the upper surface becomes smooth, and the foreign matter is easily moved by the blast air, so even the large falling snow and ice that obstructs point switching will have the tip side of the tongue rail 8. Is pushed to.

As described above, foreign matters such as flying stones and falling snow and ice that have fallen between the basic rail and the tongue rail can be surely removed, so that the point cannot be converted due to the foreign matters. In addition, this device has an advantage that it can be easily installed with almost no need to modify the track since it only attaches the piping unit to the sleeper, and that the installed state hardly interferes with the existing snow melting device.

In the above-described embodiment, the description has been given of the case where the foreign matter is simply blown off and removed. However, in some cases, a heating means for heating before the air is jetted may be provided to jet hot air. In addition to this, the piping unit equipped with the above-mentioned nozzle is used for hot water jetting or hot air jetting 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 point conversion is not possible. May be.

[0018]

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