Abstract

PURPOSE: To melt ice and snow in a clearance between a main track and a guard rail without ejecting water by circulating a heated fluid in a pipe member and forming the pipe member of a material capable of radiating the heat of the heated fluid. CONSTITUTION: When a heated fluid 28 is passed into a flow path 26, a point protecting rubber 20 is expanded by the heat of the heated fluid 28, projecting strip sections 24 are abutted against the internal surfaces of a main track 10 and a guard rail 12, and the band rubber 20 is stabilized. When the heated fluid 28 is circulated under the state, the heat of the heated fluid 28 is radiated to the outside from the point protecting rubber 20, and the heat of the heated fluid 28 is also conducted through the main track 10 and the guard rail 12 from the rubber 20. Since a recessed groove 22 is formed to the rubber 20, a space is formed among the recessed groove 22 and the internal surfaces of the main track 10 and the guard rail 12, thus inhibiting heat conduction to the main track 10 and the guard rail 12 from the point protecting rubber 20. The heat of the heated fluid 28 is radiated efficiently to open upper sections, thus melting ice and snow intruding into a clearance 16.

2. Description of the Related Art In a railroad track, for example, at railroad crossings, curves, etc., a main track for rolling the wheels of the train to guide the progress of the train and a guard rail provided along the main track are installed in parallel. There is. A narrow gap is provided between the main track and the guard rail, and the flange of the wheel can pass therethrough. By the way, since trains in cold regions have snow during the winter, snow accumulates on railroad tracks and railroad crossings, including in the gap between the main track and the guardrail. When the train wheels pass over the accumulated snow and the vehicle passes over the railroad crossing, the snow accumulated in the gap between the main track and the guardrail is compressed, and it becomes a state of pressure snow, and finally it becomes ice. Become. If this snow pressure progresses excessively, the gap may be filled with ice and snow, and the guardrail may not function and the train may derail. Therefore, a worker manually scrapes the ice and snow accumulated in the gap between the main track and the guardrail to prevent derailment of the train. However, it is inefficient to manually remove the ice and snow accumulated in the gap between the main track and the guardrail, and there is a problem in terms of work safety. Therefore, a water sprinkling type snow melting device has been proposed in which a water sprinkling pipe is laid in the gap between the main track and the guardrail, and a large amount of water ejected from the water sprinkling pipe melts ice and snow in the gap.

[0003]

However, the above-mentioned conventional sprinkler type orbital snow melting device has the following problems. We were able to achieve considerable results in melting the ice and snow in the gap with a large amount of water ejected from the water sprinkling pipe, but in addition to the large amount of water sprinkled, the water from which the ice and snow melted accumulated under the track Has the problem that the tracks will be submerged. In addition, there is also a problem that if the water accumulated under the track freezes again, the track is pushed up, and as a result, the possibility of derailment is further increased, and a sprinkler type orbital snow melting device has not been realized. Therefore, an object of the present invention is to provide a track snow melting device that can melt ice and snow in the gap between the main track and the guardrail without ejecting water.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, a track snow-melting device for melting ice and snow in a gap between a main track on which train wheels roll and a guardrail provided along the main track, which is arranged in the gap. , A pipe member made of a material capable of radiating the heat of the heating fluid and radiating the heat contained in the heating fluid. Further, in the above orbital snow melting device, the tube member may be formed by forming a gap filling member in a tubular shape for preventing foreign matter from entering the gap, and the tube member is radiated by the tube member body. The heat may be temporarily stored and then covered with a heat storage member capable of radiating.

[0005]

[Operation] The operation will be described. The pipe member arranged in the gap between the main track and the guard rail is formed of a material capable of circulating the heating fluid therein and radiating the heat of the heating fluid. Therefore, when the heating fluid is circulated inside the pipe member, the ice and snow that has entered the gap can be melted by the heat radiated by the pipe member.

In addition, in this embodiment, an orbital snow melting device at a railroad crossing will be described as an example. An example of a railroad crossing provided with the track snow melting device according to the present invention is shown in FIG. In FIG. 5, 10 is a main track on which the wheels of the train roll, and a pair of parallel tracks (only one is shown in FIG. 5) are provided in parallel. The main track 10 is made of steel. Numeral 12 is a guard rail for preventing the railroad crossing edge collapse, and a pair (only one is shown in FIG. 5) is provided along each main track 10 slightly beyond the length range of the level crossing 14, and each main track is provided. It is provided inside 10 parallel to the main track 10. Guardrail 12
Are arranged in parallel on the main track 10. The guard rail 12 is also made of steel and is formed at the same height as the main track 10. A narrow gap 16 is provided between the main track 10 and the guardrail 12, and the flange of the wheel can pass through the narrow gap 16. Normally, the gap 16 is formed to have a width of about 65 mm and a depth of about 50 mm. Reference numeral 18 denotes a snow melting device, which is arranged in the gap 16 and is provided to melt the ice and snow in the gap 16. Four examples of the snow melting device 18 provided on the railroad crossing 14 having the above configuration will be described below.

(First Embodiment) A first embodiment will be described with further reference to FIG. Reference numeral 20 denotes a wheel guard rubber which is an example of a gap filling member, and is laid inside the gap 16. The wheel guard rubber 20 is made of a heat storage material such as synthetic rubber and is formed in a long tubular shape. The width of the wheel protector rubber 20 is formed to be substantially the same as the inner width of the gap 16 and wider than the upper end width of the gap 16. The rubber wheel 20 is elastically deformable and can be pushed into the gap 16 from the upper surface of the gap 16. The guard wheel rubber 20 serves as a gap filling member and prevents foreign matter (for example, stones, dust, etc.) from entering the gap 16. In addition, four recessed grooves 22 are formed in the lengthwise direction on the outer peripheral surface of the rubber wheel 20. Further, the wheel guard rubber 20 has four ridges 24 formed on the outer peripheral surface in the length direction.
Thus, the inner surfaces of the main track 10 and the guard rail 12 can be brought into contact with each other.

Reference numeral 26 is a flow path, which is formed at the center of the rubber wheel 20. By forming the flow path 26, the rubber wheel 20 has the function of a pipe member. Channel 2
A heated fluid 28 (for example, water, ethylene glycol solution, gas, etc.) can be circulated in the unit 6. The wheel guard rubber 20 is formed of a heat storage material such as synthetic rubber as described above, but has sufficient heat resistance and pressure resistance because it allows the heating fluid 28 to pass therethrough. Further, the guard wheel rubber 20 is capable of radiating the heat of the circulating heating fluid 28 to the outside. The wheel guard rubber 20 is provided in both gaps 16 (only one is shown in FIG. 5) over the length range of the railroad crossing 14.
A circulation hose (not shown) is connected to both ends of the wheel guard rubber 20, and connects the flow path 26 to the fluid 28 heating means (for example, a heating tank with a built-in electric heater) and the fluid 28 circulation means (for example, a pump). There is. The circulation hose is connected to the heating means and the circulation means through the lower side of the main track 10.

When the heating fluid 28 (the temperature varies depending on the environment of use, for example, 60 to 80 degrees Celsius) is passed through the flow path 26, the heat of the heating fluid 28 causes the rubber wheel 20 to expand and the ridge portion 24. But the main track 10 and the guardrail 12
It contacts the inner surface and stabilizes. When the heating fluid 28 is circulated in this state, the heat of the heating fluid 28 is radiated outward from the rubber wheel 20. The heat of the heating fluid 28 is the ring rubber 2
Although it is also transmitted from 0 to the main track 10 and the guard rail 12, in the case of the first embodiment, since the groove 22 is formed in the wheel guard rubber 20, the groove 22 and the inner surface of the main track 10 and the guard rail 12 are separated from each other. Since a space is formed between them,
From the rubber wheel 20 to the main track 10 and the guardrail 12
The heat conduction to the is suppressed. Therefore, the heat of the heating fluid 28 is efficiently released and radiated upward, so that the ice and snow that has entered the gap 16 can be melted.

(Second Embodiment) The first embodiment will be described with further reference to FIG. The same members as those of the first embodiment are designated by the same reference numerals as those of the first embodiment, and the description thereof will be omitted. Reference numeral 30 denotes a pipe member, which is made of a material having a sufficient heat dissipation property (for example, metal, plastic, rubber). The pipe member 30 is pushed into the wheel protector rubber 20, which is an example of a gap filling member having an open upper surface. The heating fluid 28 can be circulated in the pipe member 30, and similarly to the first embodiment, a circulation hose (not shown) is connected to both ends of the pipe member 30, and a heating means for heating the pipe member 30 and the heating fluid 28 and I am in contact with circulation means. 32 is a heat diffusion plate,
The opened upper surface of the rubber wheel 20 is closed. The heat diffusion plate 32 is also made of a material (for example, metal, etc.) having sufficient heat dissipation.
It is made of plastic and rubber.
It is locked to the top opening edge of 0. In the second embodiment, the heat of the heating fluid 28 is radiated from the outer peripheral surface of the pipe member 30 and is radiated upward through the heat diffusion plate 32, so that the ice and snow that has entered the gap 16 can be melted. Become.

(Third Embodiment) The third embodiment will be described with further reference to FIG. The same components as those of the preceding embodiment are designated by the same reference numerals as those of the preceding embodiment, and the description thereof will be omitted. Reference numeral 34 denotes a heat storage member, which is formed of a material (for example, sponge, rubber chip, or the like) that can be radiated outward after the tube member 30 radiates heat to temporarily store the heat. Since the heat storage member 34 is arranged so as to enclose the pipe member 30, the heat from the pipe member 30 is temporarily stored and then the heat can be gradually released. Therefore, it is possible to melt ice and snow for a long time without continuously heating or circulating the heating fluid 28. In this embodiment, the heating fluid 28 of 60 degrees Celsius is used.
Was circulated at intervals of 4 hours, but sufficient melting ability could be exhibited. 38 is a heat insulating support, and the heat storage member 34
And the main track 10, guardrail 12, etc.,
It is provided in order to prevent conduction and release of heat held by the heat storage member 34 and to more effectively melt ice and snow for a long time. In particular, in the third embodiment, the pipe member 30 is arranged at a position where the pipe member 30 is changed upward so that heat can be moved upward.

(Fourth Embodiment) A fourth embodiment will be described with further reference to FIG. The same components as those of the preceding embodiment are designated by the same reference numerals as those of the preceding embodiment, and the description thereof will be omitted. The fourth embodiment is an example in which bolts 36 and the like for fixing the guardrail 12 are arranged in the gap 16. The pipe member 30 is arranged in an extra space in the gap 16 to prevent interference with the bolt 36 and the like. Therefore, the outer diameter of the pipe member 30 is determined depending on the cross-sectional size of the extra space. Further, the heat insulating support 38 prevents the heat of the heat storage member 34 from being conductively released via the bolt 36 in addition to the main track 10 and the guard rail 12.

In each of the above-described embodiments, the pipe member 30 disposed in the gap 16 or the wheel guard rubber 20 serving also as the pipe member is provided.
The heating fluid 28 can circulate inside and is formed of a material capable of radiating the heat of the heating fluid 28. Therefore, when the heating fluid 28 is circulated, it is possible to melt the ice and snow that has entered the gap 16 by radiant heat. Since the water that accumulates under the track is only water that melts ice and snow, a large amount of water does not accumulate under the track and it is possible to prevent the track from being submerged. In addition, since the amount of water that accumulates under the track is extremely small, it is possible to prevent obstacles such as freezing and pushing up the track, thus ensuring the safety of train operation. The various preferred embodiments of the present invention have been described above,
The present invention is not limited to the above-described embodiments. For example, the snow melting device according to the present invention is not limited to railroad crossings, but may be a curved portion or a point portion of a railroad track, and the gap 16 may be relatively narrow and unchanged. Needless to say, many modifications can be made without departing from the spirit of the invention, such as installation.
