Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device capable of securely supporting a guard angle for preventing derailment in a curved section of a concrete track floor of a railway.

[0002]

[Prior art]

 Conventionally, as this type of support device, as shown in FIGS. 6 and 7, there has been provided a device having a structure in which a roadbed can be used for a gravel track. That is, in FIG. 6, a pedestal 35 for holding the lower surface of the rail 31 from a fixed end 34 which is engaged with a leg seat (flange) 32 on a lower outer side of the rail 31 and is fixed by a bolt and nut fixture 33. A cast body 37 having a bottom portion 36 greatly swelled downward and an attachment 38 in which a corresponding side surface abuts against a side surface on the free end side of the body 37 are provided. The nut 39 is integrally connected by tightening the fixing member 39. At the time of the tightening, a predetermined vertical frame 41 of the guard angle 40 is inserted into a gap formed on the upper side. , And is held by an engaging portion 42 composed of a projection and a recess.

In FIG. 7, a pedestal 54 for holding the lower surface of the rail 31 from a fixed end 53 which is fixed to a leg seat 32 on a lower outer side of the rail 31 with a bolt 52 and a nut 52 via an attachment metal fitting 51. The bottom surface 55 having the bottom 55 is bulged largely downward, and the guard angle attachment portion formed at the upper part on the free end side of the casting body 56 is brought into contact with the side surface of the vertical frame 58 of the guard angle 57 and the lower surface of the horizontal frame 59. The horizontal frame 59 is configured to be held by a bolt and nut fastener 60.

[0004] Since the guard angle support devices of the conventional types as described above have a shape in which the bottom portion is greatly swelled downward, it is necessary to lay it at least 10 cm below the rail. It can be used only on gravel roadbeds where space is available. In addition, the point of application of the lateral force acting on the guard angle due to the eccentric force of the train is located at the free end of the main body, and it is supported at the fixed end with the bottom of the main body as a fulcrum. A large opposing force acts on the fixed end side of the main body by the leverage action.

[0005] As described above, in the case of a concrete track floor, only a space of about 5 cm is provided under the rail, so that it is not appropriate to use such a type of guard angle support device, and it is not appropriate to use a guard angle support device. There were problems such as structural weakness in supporting the lateral force acting on the angle.

[0006]

[Problems to be solved by the invention]

 Therefore, the present invention is mainly intended for railways that can be laid without any special pre-treatment work on existing concrete roadbeds, and that can easily support the lateral force acting on the guard angle. The purpose is to obtain a guard angle support device for preventing derailment in curved sections of concrete track tracks.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above point of view, and includes a lower outer leg seat of a rail formed at one end and an engaging portion engaged with a bolt or the like. A base having a required width in which a rail supporting portion that traverses the lower surface of the rail and an extension having a predetermined length extending in the extension direction of the rail supporting portion are integrally formed; A guard angle mounting body of a predetermined length integrally rising at a predetermined distance from a portion where the end of the leg seat inside the lower part of the rail is located, and means for elastically supporting the end of the extension of the base. And a guard angle fixed to and supported by the guard angle mounting body.

[0008]

[Embodiment of the invention]

 Next, the present invention will be described with reference to FIGS. FIGS. 1 and 2 are cross-sectional views showing the configuration of an embodiment of the present invention, in which a lower leg (flange) 22 of a lower end of a rail 21 formed at one end is held from below, or bolts or the like are used. An engaging portion 1 to be engaged, a rail support portion 2 for transversely supporting the lower surface of the rail 21, and an extension portion 3 having a predetermined length extending in the extension direction of the rail support portion 2 are integrally formed. A base 4 having a required width and a guard angle attachment of a predetermined length, which stands on the extension 3 of the base 4 at a predetermined distance from a position where the end of the leg seat 23 inside the lower part of the rail 21 is located. The body 5 is implanted integrally.

A guard angle horizontal frame tip support 6 is integrally formed at the upper end corner of the guard angle mounting body 5, and the lower surface of the horizontal frame 25 of the guard angle 24 is applied to the top surface of the guard angle mounting body 5. Then, the tip 26 of the horizontal frame 25 is inserted into and engaged with the guard angle tip bearing 6. Then, the inner surface of the vertical frame 27 of the guard angle 24 is applied to the step 7 formed on the upper part of the side surface of the guard angle mounting body 5. As a result, the lower side surface of the guard angle mounting body 5 and the outer surface of the vertical frame 27 of the guard angle 24 form a plane. Thereafter, a guard angle push plate 8 which abuts on a plane formed by a lower side surface of the guard angle mounting body 5 and an outer surface of a vertical frame 27 of the guard angle 24, and a step 9 which is engaged with a leg seat 23 on the lower inner side of the rail 21. The guard angle push plate 8 is firmly fixed to the lower portion of the guard angle attachment 5 with bolt and nut fixing tools 11.

In this case, the base 4 is supported at its distal end by bolts and nuts fixtures 12, and the lower ends of the bolts of the fixtures 12 are concretely covered by elastic materials 14 such as rubber via pedestals 13. It is elastically supported by the roadbed 61. Reference numeral 15 denotes a window hole formed in the lower part of the guard angle mounting body 5, which is a work space when the guard angle push plate 8 is fixed to the lower part of the guard angle mounting body 5 with the fixing tool 11. . Reference numeral 16 denotes an engaging portion formed of a projection and a recess formed on the guard angle pressing plate 8 and the guard angle 24, and the engagement allows the guard angle 24 to be fixed to the guard angle pressing plate 8. It is configured as follows.

FIG. 3 is a cross-sectional view showing the configuration of another embodiment of the present invention, in which the guard angle 24 is fixed by a guard angle pressing plate 8a as a part corresponding to the attaching member 10 in the above embodiment. The base 4 is integrally provided with a projection 17 for locking to a leg seat 23 inside the lower part of the rail 21.

FIG. 4 is a cross-sectional view showing the configuration of still another embodiment of the present invention, in which the tip 26 of the horizontal frame 25 of the guard angle 24 is free, and the guard angle push plate 8 a is engaged with the base 4. Projection 18 is provided integrally.

The structure A of each of the above embodiments is laid between sleepers in a curved section 62 of a concrete track floor track of a railway as shown in FIG.

[0014]

[Effect of the invention]

 As is clear from the above description, according to the present invention, it is possible to lay quickly and easily mainly in the curved section of the existing concrete roadbed without performing any special pretreatment work.

[0015] Furthermore, since the force applied to the base by the lateral force acting on the guard angle is supported by the rail side and the guard angle mounting body side opposite thereto, it can be supported without difficulty, and the strength can be improved. It is robust.
