Description

  The present invention relates to a filling structure in a flange way through which a wheel flange of a rail vehicle passes between a rail and a road surface at a railroad crossing between a railroad rail, an industrial carriage rail such as a crane, and a road on which people and vehicles pass. .

  Patent Document 1 proposes a tubular material that is formed of an elastic material such as rubber and that has a substantially trapezoidal cross section and has a hollow portion as a protective material that closes the flange way.

JP 2001-254303 A

  In the flange way, the tubular material is pressed and deformed by a plurality of wheel flanges each time the rail vehicle passes. For this reason, the restoring property, strength, and durability of the cylindrical material are required. Moreover, since the cylindrical material is exposed in the flange way and is directly exposed to sunlight and wind and rain, sufficient weather resistance is required. However, it is estimated that the cylindrical material disclosed in the cited document 1 is deteriorated as the installation time elapses, and the restorability and strength are reduced and the durability is lowered. And the partial defect | deletion of a cylindrical material may lead to accidents, such as a pedestrian.

  SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a filling structure for a railroad crossing flange way that provides sufficient restoration and durability.

  The invention according to claim 1 is a clogging structure in a flange way between an in-gauge block and a rail at a railroad crossing, the hollow elastic protective member installed between the in-gauge block and the rail, A composite sealing plate disposed on the upper portion of the elastic protective member from the inner rail block toward the rail, and covering the flange way, and the composite sealing plate is a hard and flexible flexible protective material, and at least A steel plate spring whose surface is covered with the protective material, and a base end portion of the plate spring is supported by a support member attached to the in-gauge block.

  According to the above configuration, the front end side of the composite seal plate is pushed down by the wheel flange passing through the rail and the front end side of the leaf spring is bent downward, and the elastic protection member is pressed downward to be compressed and deformed. Therefore, the composite seal plate is stably restored to the original shape by the leaf spring. Further, since the elastic protective member is covered with the composite seal plate, weather resistance of the elastic protective member is greatly improved. Furthermore, since the surface of the leaf spring is covered with a protective material, rust is hardly generated in the leaf spring, and the leaf spring does not directly contact the wheel flange and wear.

  In the above configuration, the leaf spring is preferably formed with a groove portion for bending along the length direction of the rail on the back surface side of the intermediate portion. According to the above configuration, the leaf spring is stably bent at a fixed position by the groove.

  Furthermore, in the above configuration, it is preferable that the composite seal plate has a protective material disposed on the surface and a leaf spring disposed on the back surface of the protective material.

  Furthermore, in the above configuration, it is preferable that the composite seal plate has a leaf spring inside the protective material.

  According to the first aspect of the present invention, it is possible to provide a filling structure for a railroad crossing flange way that provides sufficient restoration performance and strength.

AA sectional view shown in FIG. It is the B section enlarged view shown in FIG. It is the B section enlarged view shown in FIG. It is a cross-sectional view showing Example 2 of the composite seal plate. It is a cross-sectional view of a composite seal plate showing when passing through the wheel flange.

[Example 1]
Embodiment 1 of the present invention will be described below with reference to FIGS.

  As shown in FIG. 4, a rising-inside block 12 is installed between the pair of left and right rails 11 in the railroad crossing 10. An angle-shaped guard rail 13 is fixed to the edge of the raised inner block 12 facing the rail 11. A flange way 14 through which the wheel flange WF passes is formed between the rail 11 and the inter-inside block 12. In addition, an out-of-running block 15 is installed outside the rail 11 in the railroad crossing 10.

  As shown in FIGS. 2 and 3, a tie plate 18 is installed via a tie plate 17 in the rail fastening groove 16 between the inner block 12 and the outer block 15. It is fixed in the rail fastening groove 16 by a wedge 19 penetrating both edges. Furthermore, the rail 11 is arrange | positioned through the rail pad 20 on the surface of the tie plate 18, and the rail 11 is being fixed on the rail pad 20 through the lower flange by the left and right rail fixing tools 21A and 21B.

  The left and right rail fixtures 21A and 21B are used to fix the lower flange of the rail 11 and the rail pad 20 via a clip with bolts and nuts. A V-shaped spring, a coil spring, or the like is attached to the bolt portion between the clip and the nut. Intervened.

  A blocking member 31 having a substantially channel-shaped cross-section with the back surface opened is installed between the rail 11 and the outer block 15, and a spacing plate 32 is housed inside the blocking member 31. The hatched portions around the rail fixtures 21A and 21B indicate fillers.

  The filling material that fills the flange way 14 is a hollow elastic protective member 22 made of rubber or resin, which is installed on the upper part of the fixture 21A, and from the in-gauge block 12 to the rail 11 on the surface side of the elastic protective member 22. And a composite seal plate 23 that protrudes horizontally toward the rail 11 so that the tip portion approaches the rail 11. The composite seal plate 23 includes a flexible plate-shaped protective member 24 that is hard and can be bent, and a flat plate spring 25 made of steel and disposed on the back surface of the protective member 24. A support member 26 protrudes from the guard rail 13 of the in-gauge block 12 by welding or the like. The base end portion of the leaf spring 25 is supported on the support member 26 by a plurality of detachable couplers 27 such as countersunk screws. The composite seal plate 23 is disposed so that the surface of the rail inner block 12 and the upper flange of the rail 11 are flush with each other, and the flange way 14 is covered. The protective material 24 is a hard material that is sufficiently durable to be pressed against the crossing vehicle of the railroad crossing and the pressure contact of the wheel flange WF, has little wear, and can be bent with weather resistance, such as urethane. It is selected from synthetic rubber such as rubber and resin. Further, bending grooves 24 a and 25 a for allowing bending are formed along the length direction of the rail 11 at the front end side of the support member 26 at the intermediate portion between the back surfaces of the protective member 24 and the leaf spring 25. . The composite seal plate 23 is not bent by the load of a passerby or crossing vehicle, but is designed to be bent by the load of the wheel flange WF when the wheel W of the rail vehicle passes through the rail 11. Furthermore, the front end portion of the leaf spring 25 is sufficiently retracted from the front end portion of the protective member 24, and the wheel flange WF can be prevented from coming into direct contact with the leaf spring 25. Here, the elastic protection member 22 and the composite seal plate 23 have been described so as to be continuous over the entire length of the flange way 14, but the plurality of elastic protection members 22 and the plurality of composite seal plates 23 are connected to each other. It may be a thing.

  In the above configuration, the rail fastening groove 16 between the rail 11 and the raised block 15 is closed by the closing member 31 at the railroad crossing 10, and the flange way 14 is covered with the elastic protection member 22 and the composite seal plate 23. , You can safely traverse passers-by and start-up vehicles. Further, since the flange way 14 is covered with the composite seal plate 23, direct sunlight is blocked from the elastic protection member 22 and it is prevented from being directly exposed to wind and rain. Long life can be achieved. Further, when the rail vehicle passes along the rail 11 and the wheel flange WF moves along the flange way 14, the outer peripheral portion of the wheel flange WF abuts on the front end side surface of the composite seal plate 23 and pushes down the composite seal plate. 23 rolls on the surface. As a result, the composite seal plate 23 is bent downward at the front ends of the protection plate 24 and the leaf spring 24 around the groove portions 24a and 25a, and is further pressed against the composite seal plate 23 to pressurize and deform the elastic protection member 22. . Thereby, the wheel flange WF passes through the flange way 14. When the wheel flange WF finishes passing through the flange way 14, the composite seal plate 23 is returned to the original posture by the elasticity of the elastic protection member 22 and the leaf spring 25.

  According to the first embodiment, the composite seal plate 23 is pressed by the wheel flange WF passing through the rail 11 and the tip side is bent downward, and the elastic protection member 22 is compressed and deformed by the composite seal plate 23. Since the leaf spring 25 restores the composite seal plate 23 after passing through the wheel flange WF, the restoration performance is greatly improved. Further, since the elastic protection member 22 is covered with the composite seal plate 23, it is not directly exposed to direct sunlight, and the durability can be greatly improved. Furthermore, in the composite seal plate 23, since the leaf spring 25 is covered with the protective material 24, the contact of the leaf spring 25 with the wheel flange WF can be avoided and the occurrence of rust can be prevented. Furthermore, since the groove portions 24a and 25a for bending are formed in the protective material 24 and the leaf spring 25 along the length direction of the rail 11, the front end side of the composite seal plate 23 is stabilized downward at a fixed position by the wheel flange WF. And can be bent.

[Example 2]
In the first embodiment, the composite seal plate 23 has the protective material 24 attached to the surface of the plate spring 25. However, in the second embodiment, the plate spring 25 is integrally molded in the protective material 24. A second embodiment will be described with reference to FIGS. 5 and 6. Note that the same members as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  As shown in FIG. 5, the composite seal plate 43 has a plate spring 45 provided in the vicinity of the back surface of a plate-shaped protective member 44 having a predetermined thickness by integral molding. A bending groove 44 a is formed on the back side of the protective material 44. Further, a notch 44 b for exposing the leaf spring 45 is formed on the back surface side of the protective material 44. In the figure, the bending groove 44a and the notch 44b on the back surface of the protective material 44 are formed continuously, but they may be formed independently. As a result, the leaf spring 45 can be directly disposed on the support member 26 via the notch 44 b of the protective member 44, and the leaf spring 45 can be directly fixed to the support member 26 using the connector 27.

  According to the said Example 2, there can exist an effect similar to Example 1. FIG.

  Although the protective material 44 and the leaf spring 45 are integrally molded, the protective material 44 and the leaf spring 45 are separately molded, and the leaf spring 45 is fitted into the mounting hole formed in the protective material 44 and integrated. Also good.
