17 is a sectional view taken along line DD of FIG. 15, and FIG. 17 is a sectional view taken along line EE of FIG. In the figure, 1 is a basic rail, 2 is a floor board, and 3 is a tongue rail which moves on the floor board 2 as appropriate to change the direction of a train or the like.
Reference numeral 4 denotes a sleeper, and 5 denotes a main body case of an electric warm-air type snow-melting device mounted and fixed on the sleeper 4, and a suction port 6 is provided at a lower front portion of the main body case 5. Further, on the upper part of the front surface of the main body case 5, there is provided a blow-out duct 7 protruding toward the basic rail 1 and having a substantially box-shaped cross section. Reference numeral 8 denotes a mounting plate installed in the main body case 5, and the mounting plate 8 has a blower 9, a heater 10 having a radiation fin, and an overheat preventive device 1.
1 is fixed respectively. Reference numeral 12 denotes a lid mounted and fixed on the upper surface of the main body case 5, and 13 denotes a box-shaped air duct connected and fixed to one end of the blow-out duct 7 and having a rectangular cross section.
3 is a sleeper 4 below the basic rail 1 and the tongue rail 3
A plurality of hot air outlets 14 that blow hot air upward toward the basic rail 1 and slit-like hot air outlets 15 that laterally blow warm air toward the floor plate 2 are provided. ing. Further, 16 is a ballast that serves as a roadbed, and the ballast 16 is in contact with the bottom portion of the blower pipe 13.

Next, the operation of the conventional electric hot-air type snow-melting device constructed as described above will be described. When a switch (not shown) is turned on and the blower 9 and the heater 10 are energized, the blower 9 draws in air from the suction port 6 of the main body case 5 (in the direction of arrow k in the figure), and the heater It is discharged toward 10. The discharged air is heated by the heater 10 to become warm air, which is discharged from the warm air outlets 14 and 15 of the blower pipe 13. Then, the warm air causes a snow melting action in the vicinity of the point portion. At this time, the hot air discharged from the slit-shaped hot air outlets 15 on the side surfaces correctly hits the side surface of the floor plate 2 to exhibit the most efficient snow melting action.

However, in the installation of the conventional electric hot-air type snow melter configured as described above, the main body case 5 is fixed to the sleeper 4, and the blower pipe 13 is placed on the ballast 16. The relative positional relationship between the slit-shaped warm air outlet 15 and the side surface of the floorboard 2 changes depending on the position of the surface of the ballast 16. Therefore, ballast 16
If there is a difference in height between the surface positions, there is a problem that the warm air blown out from the warm air outlets 15 on the side surface does not hit the side surface of the floorboard 2 correctly. There is also a problem that the warm air blown out from the warm air outlet 15 on the side surface is blown by the air blown from the outside before hitting the floorboard 2, so that the warm air cannot be properly applied. Further, there is a possibility that the blower pipe 13 may move due to vibrations when passing a train, and may directly contact the metal parts of the points such as the basic rail 1 and the floor plate 2 to impair the electrical insulation. There was also a defect. In addition, the surrounding dust or the like adheres to the grease or the like applied to the tongue rail 3 to make it easy to move on the floor plate 2, and the dust adheres to the side surface of the floor plate 2 to prevent the side surface of the floor plate 2 from being heated. There were some problems. Due to these problems, there is a problem that an effective snow-melting action cannot be performed, the performance originally possessed by the electric warm-air type snow-melting device cannot be sufficiently exhibited, and the snow-melting ability is deteriorated.

As described above, according to the present invention, the cross section T
By placing both shoulders of the air duct formed on the sleeper on the sleeper, the installation height of the air duct is regulated at a predetermined position, and the size of both shoulders is greater than the dimension from the end face of the sleeper to the floorboard. Because it is small, even if the installation position of the air duct shifts to the left or right due to vibration when a train passes, both shoulders of the air duct do not contact the floor plate, and the electric warm air type snow melter originally has it. It is possible to fully exert the performance that is present.

Further, since the width of the blower pipe is set to a width that can be installed on the sleeper, the installation height of the blower pipe is restricted to a predetermined position and the movable limit is attached to the lower surface of the blower pipe. Since the installation position of the blower tube in the left-right direction can be arbitrarily adjusted by the member, the movement of the blower tube can be regulated and the warm air can be blown to a predetermined position.

Further, by providing a locking member having a protrusion that is installed between the sleepers adjacent to the front end of the blower pipe, the installation height of the blower pipe can be restricted to a predetermined position, so that the height of the ballast is increased. The warm air from the hot air outlet on the side surface can also be discharged to a predetermined position regardless of the temperature.

Further, the installation height of the blower pipe is regulated to a predetermined position by a locking member provided between adjacent sleepers,
Moreover, since the mounting length of the locking member on the sleeper can be adjusted, the installation position of the blower pipe in the left-right direction can be appropriately set. Furthermore, since the locking member is a separate part from the blower pipe, the blower pipe can be attached to the point portion after the blower pipe is placed, and the placement work can be performed easily.

Further, the installation height of the blower pipe is restricted to a predetermined position by the locking member provided between the adjacent sleepers,
Moreover, since the mounting length of the locking member on the sleeper is smaller than the dimension from the end surface of the sleeper to the floor plate, even if the installation position of the blower pipe shifts to the left or right due to vibration due to passage of a train, etc. No contact with the floorboard.

Further, the installation height of the blower pipe is regulated to a predetermined position by the leg portions provided on the lower surfaces of both shoulders of the blower pipe placed on the sleeper, and water generated by snow melting is Since it flows into the gap formed by the sleepers, both shoulders and legs, it can be prevented from flowing into the hot air outlet on the side surface formed on both shoulders.

The contact height can be prevented and the installation height of the blower pipe can be restricted to a predetermined position.

Further, since the groove formed by the blower pipe, the basic rail, the sleepers and the ballast is closed with the electric insulator having the vibration-proof property, the blower pipe is not affected even when vibrations such as passing trains are applied. And the basic rail can be prevented, the installation height of the blower pipe can be regulated at a predetermined position, and the air blown into the groove is blocked, so the warm air discharged from the hot air outlet can be discharged from the side surface of the floorboard. Since it can be applied correctly to the snow, the snow melting efficiency can be improved.

Further, by using an electric insulator having good thermal conductivity as the electric insulator interposed between the blower pipe and the basic rail,
Even if vibrations such as passing trains are applied, contact between the blower pipe and the basic rail can be prevented, the installation height of the blower pipe can be restricted to a predetermined position, and the heat of the blower pipe heated by warm air can be controlled. Since the snow can be directly transmitted to the basic rail, the snow melting efficiency can be further improved.

Further, the electric insulator interposed between the blower pipe and the basic rail is provided along an appropriate position on the side surface of the basic rail on the outer side of the track, so that vibration due to train passage or the like may occur. It is possible to prevent contact between the blower pipe and the basic rail of
Since the installation height of the blower pipe can be regulated at a predetermined position, and the snowfall can be prevented from directly contacting the side surface of the basic rail to reduce heat loss, the snow melting efficiency can be further improved. Further, since the position of the air duct is arranged, the efficiency of installation work can be improved.
