Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting bracket for a rail heater to be mounted on a rail for the purpose of snow damage countermeasures and freeze prevention, and a combined structure of the heater and the mounting bracket.
[0002]
[Prior art]
In the point of the railroad, the point may become unconvertible due to the influence of snow covered snow or snow brought in by the train, so the point or the inversion is prevented by heating and melting the point or its surroundings. .
Generally, as an electric heating type heat transfer type point heater, there are a basic rail heating type for heating a rail rail and a floor plate heating type for heating a floor plate laid on the lower side of a sliding movable rail. This basic rail heating type is a type that heats the rail by attaching a heater to the rail side surface, but the rail side surface has a curvature, and since there is no locking structure dedicated to the heater, conventionally, A heater was installed by passing bolts through the side of the rail. However, in this method, the work of drilling bolt holes on the rail side surface is difficult, and there is a problem that re-drilling is required due to the effects of rail creep, etc., so the heater is pressed against the rail side surface. Spring pressure welding heaters that are mounted on the side of the rail by means of mounting brackets have become widespread.
[0003]
The original spring pressure welding heater mounting bracket is a result of the lateral displacement of the heater between the heater and the mounting bracket due to the vibration caused by the train passing or the impact of snow and snow. In order to prevent this from happening, to prevent this, as shown in Japanese Utility Model Publication No. 4-23921 (Registered No. 1956566), a locking projection is provided on the web of the heater mounting bracket to prevent lateral displacement of the mounting bracket. The method was already known.
[0004]
[Problems to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION
Next, a preferred embodiment of the rail heater mounting bracket according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing an example of a state in which a predetermined heater 2 is mounted on a rail A by a rail heater mounting bracket 1 according to the present invention. Although not shown in FIG. 1, the mounting bracket 1 and the heater 2 are configured to have the coupling structure 3 shown in FIGS. 2 to 8.
[0019]
The mounting bracket 1 is configured such that the heater 2 is pressed against the rail A by the presser bracket 7 while receiving the spring pressure of the presser spring 9, and the bent portion 4 a having a bent portion 4 a at the tip thereof is bent. A shaft support portion 5 is formed at the opposite end of the portion 4a, and a shaft bar 6 is inserted into the shaft support portion 5 and is prevented from being detached by a locking pin (not shown). 7a is formed with the rising plate portion 7b and the shaft rings 8 and 8, and the shaft rings 8 and 8 of the presser fitting 7 are inserted into the shaft support portion 5 so as to be rotatable. ing.
[0020]
In the mounting bracket 1, a U-shaped gripping bracket 10 with a locking portion 10 a, 10 a is fixed to the rising plate portion 7 b of the presser bracket 7, and the gripping bracket 10 can be brought into close contact with the heater 2. As described above, the coupling structure 3 is formed by the heater 2 and the gripping metal fitting 10.
[0021]
As an example of the coupling structure 3, first, as shown in FIG. 2, an appropriate projection 2a is formed on the outer surface 2b of the metal main body so that the heater 2 has a projection structure, while corresponding to each projection 2a. In addition, there is a coupling structure 3 in which a locking hole portion 10b which is a through hole is formed and the gripping metal fitting 10 is formed as a structure with a hole, and the gripping metal fitting 10 is brought into close contact with the heater 2. In this coupling structure 3, the main body of the heater 2 is accommodated between the locking portions 10 a and 10 a, and the protrusions 2 a are fitted into the locking holes 10 b to be engaged with the projections and recesses, and the outer surface 2 b of the heater 2 is engaged. The holding metal fitting 10 can be brought into close contact with the heater 2 so that the inner surface 11 of the holding metal fitting 10 is brought into contact with the heater.
[0022]
The heater 2 may be made of an aluminum die-cast with a sheath heater (not shown) built therein, and is formed by processing a molding die to form a protrusion 2a when molding the main body. The protrusion 2a is formed in a thick rectangular shape in the figure, but is not limited to this, and may have a shape such as a thick disk shape or other shapes. Further, the number to be formed is not limited to three as shown in the figure. For example, a total of two may be formed near both ends in the longitudinal direction of the main body.
[0023]
The holding metal fitting 10 has a thickness approximately equivalent to the height of the protrusion 2a or appropriately thicker than the protrusion 2a so that the protrusion 2a does not protrude from the outer surface 12 when the protrusion 2a is fitted and engaged with the concave and convex portions. It is made of a metal plate such as aluminum or stainless steel. The locking hole portion 10b is formed at the time of molding the metal fitting, but it may be formed in a concave shape with a bottom instead of a punched hole as shown in the figure, and the shape and number of the plan view thereof may be different from each other. As long as it corresponds to the protrusion 2a, it is not limited to the illustrated one. For example, it can be formed into a thick disk shape, or two can be formed, one at each end in the longitudinal direction of the holding fitting 10.
[0024]
According to this coupling structure 3, when the heater 2 is placed in the gripping metal 10, an uneven engagement state in which each protrusion 2 a is fitted in each locking hole 10 b is obtained, so that the outer surface 2 b of the heater 2 and the gripping metal 10 The heater 2 can be mounted on the side surface of the rail A in an integrated state in which the inner side surface 11 is closely in contact with the inner surface 11. At this time, the heater 2 is restricted in its vertical movement by the locking portions 10a, 10a, and is also restricted in relative movement in the left-right direction with respect to the gripping metal fitting 10 by the uneven engagement between the protrusion 2a and the locking hole portion 10a. Become so. In addition, since the heater 2 and the holding metal fitting 10 are formed by molding both the projection 2a and the locking hole portion 10a involved in the respective concave-convex engagement, the positions of the projection 2a and the locking hole portion 10a. And, the shape is unified, and a different recess is not formed every time the gripping fitting 10 is remounted. Therefore, even if it replaces with another holding | grip metal fitting 10, it comes to be provided with the interchangeable flexibility which does not cause trouble in the close integration state with the heater 2. FIG. In this regard, in particular, if the locking hole portion 10b is formed slightly longer in the longitudinal direction than the protrusion 2a, a margin is obtained for the attaching / detaching operation for fitting and releasing, which is more preferable.
[0025]
Next, as shown in FIGS. 3 and 4, the coupling structure of the heater 2 and the holding metal fitting 10 is a heater having a corrugated structure by forming a corrugated portion 12 having a fine corrugated shape in the longitudinal section on the outer surface 2b. The coupling structure 3A can be made of 2A and a gripping metal fitting 10A having a corrugated structure in which a corrugated portion 13 corresponding to the corrugated portion 12 is formed. The waveform portions 12 and 13 in this case can be a continuous triangular shape having a fine cross section as shown in FIG. 3 or a smooth waveform having a sine curve shape as shown in FIG. Of course, anything else is acceptable. Moreover, as shown in the drawing, the present invention is not limited to the case where it is formed over substantially the entire surface in the longitudinal direction, and a corrugated portion may be formed in a part thereof.
[0026]
According to the coupling structure 3 </ b> A, the heater 2 </ b> A is restricted from moving up and down by the locking portions 10 a and 10 a, and the left and right relative movement is restricted by the meshing engagement between the corrugated portion 12 and the corrugated portion 13. Of course, since the corrugated part 12 and the corrugated part 13 are formed by molding, it is needless to say that, like the coupling structure 3, interchangeable flexibility is provided. Further, the relative movement of the left and right is regulated by the meshing of the corrugated portions 12 and 13, but the meshing of the corrugated portions 12 and 13 in this case can be maintained as long as both peak and valley portions mesh with each other, Even if the position of the gripping bracket 10A slightly deviates from side to side, it is possible to obtain both integrated states by meshing. In this respect, the flexibility of close integration is high, and the attachment / detachment operation can be performed easily. .
[0027]
Further, as shown in FIG. 5, the coupling structure is a heater 2B in which the heater 2 has a high friction coefficient structure with a high friction coefficient formed on the outer surface 2b, while the gripping metal fitting 10 is It can be set as the coupling | bonding structure 3B which consists of the heater 2B and the holding | grip metal fitting 10B as the holding | grip metal fitting 10B which becomes the high-friction coefficient structure in which the side surface 11 has the corresponding high friction coefficient surface. Here, in order to make the outer surface 2b and the inner surface 11 have a high coefficient of friction surface, for example, as shown in FIG. Or although not shown in figure, embossing can be given and it can be set as an embossed structure. Furthermore, instead of the connection structure 3B, as shown in FIG. 6, a connection structure 3C can be obtained by providing a striped steel plate structure using a striped steel plate 15 with a striped pattern. In the case of the coupling structure 3C, a tightly integrated state is obtained by the engagement of the protrusions on the surfaces of the striped steel plates 15 with each other. Further, in both cases of the coupling structure 3B and the coupling structure 3C, those provided over the entire surface in the longitudinal direction as shown in the figure are preferable, but those provided in part may be used.
[0028]
According to the coupling structure 3B and the coupling structure 3C, the vertical movement of the heater 2B is regulated by the locking portions 10a and 10a as in the coupling structure 3, but the horizontal movement between the heater 2B and the heater 2B having a high friction coefficient. Therefore, it is regulated by the close engagement with which the holding fitting 10B comes into contact or the close engagement of the protrusions on the striped surface of the striped steel plate 15. Needless to say, the coupling structure 3B and the coupling structure 3C have interchangeable flexibility similar to the coupling structure 3 and, as with the coupling structure 3A, are highly integrated. It will be a thing.
[0029]
Next, all of the above coupling structures relate to the structure of the inner surface 11 of the gripping metal fitting 10, but the present invention is not limited to such a structure, and an intermediate material is interposed as shown in FIG. It can also be set as the coupling structure 3D made. This coupling structure 3D is designed to obtain an integrated state in which the heater 2D and the gripping metal fitting 10D are engaged and in close contact with each other. The heater 2D has the above-described structure with protrusions, corrugated structure, high friction system coefficient structure, striped steel plate. Any one of the structures (the one shown in the figure is a high friction system coefficient structure), the gripping bracket 10D includes an intermediate member 16 to be inserted between the heater 2D, and the intermediate member 16 is provided with the heater 2D. Are provided with any one of a structure with a hole or a recess, a corrugated structure, a high friction coefficient structure, and a striped steel structure, and each structure is fixed to the inner surface 11 so as to face the heater 2 side. Yes.
[0030]
In this connection structure 3D, the intermediate material 16 is fixed to the inner side surface 11 so that the intermediate material 16 is brought into close contact with the heater 2 instead of the inner side surface 11 to obtain an integrated state. Can be provided with any structure corresponding to the holding metal fittings 10, 10A, 10B, 10C, so that the same operational effects as the coupling structures 3, 3A, 3B, 3C, 3D corresponding to the respective structures can be obtained. Can do. In addition, because of the interposition of the intermediate material 16, the gripping metal fitting 10 itself is a normal U-shape that does not need to be processed to form a hole or a structure with a recess or a corrugated structure, preferably as shown in the figure. All four sides may be provided with side walls, and the manufacturing is easy and simple, and the manufacturing cost can be reduced. Moreover, since the holding | grip metal fitting 10 itself is applicable with respect to any type of intermediate material 16, it becomes a highly versatile thing so much. Of course, it is needless to say that the interchangeable flexibility is provided in the same manner as the coupling structures 3 and 3A.
[0031]
In particular, when the coupling structure 3D is used, as shown in FIG. 8, a reflective paint is applied to the surface, a reflective plate is fixed, heat insulating coating material is adhered, heat reflection or heat insulation is provided. It is preferable that the heater 2 is configured by interposing a reflective heat insulating material such as by interposing a conductive intermediate plate 17. If it carries out like this, since the heat of the heater 2 will be interrupted | blocked by reflective heat insulating materials, such as the intermediate | middle plate 17, a rail can be heated efficiently.
