Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency seam device for protecting a damaged portion of a rail in case of damage to the rail and allowing the train to pass slowly, particularly a connecting track. Or, it relates to a rail emergency joint device in a combined track.

[0002]

2. Description of the Related Art Conventionally, general railroad tracks such as ballast tracks and slab tracks have already been put into practical use as an emergency seam device when rails are damaged. In a connected track to be installed or a combined track in which a train and a car run in parallel, the distance between the rail and the concrete block is narrow, and it is difficult to install parts, and there is no hindrance to road traffic and train running. The current situation is that development is delayed due to reasons such as the need for quick and safe construction.

In order to solve the above-mentioned conventional problem, as shown in FIG. 4, a joint plate 2 for holding a damaged portion of a rail 1 from both sides and a groove formed on a side surface of the joint plate 2 are fitted. The receiving member 3 having a fitting convex portion, the fixing metal fitting 5 installed by being joined to the concave groove side wall of the concrete block 4 on which the rail 1 is laid, and the fixing metal fitting 5 rotatably screwed to the head A space holding bolt 6 that can be brought into contact with and separated from the side surface of the receiving tool 3, and the space holding bolt 6 is rotated so that the seam plate 2 is pressed against the side surface of the rail 1 via the receiving tool 3. Proposed. (See JP-A-6-193002)

[0004]

However, in the structure described above, the number of parts is large and the rail 1 is also mounted.
Since the space-holding bolt 6 has to be rotated from a narrow gap between the concave groove of the concrete block 4 and the concrete groove 4, the work is difficult, and it cannot be said that the conventional problems have been sufficiently solved. There is also a problem that an insulating plate 7 for preventing a leakage current must be interposed between the joint plate 2 and the rail 1.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention, therefore, to provide an emergency seam device which can completely solve the above-mentioned conventional problems, and a seam member for holding a damaged portion of a rail from both sides. And a fixing member joined to the side wall of the concave groove of the concrete block on which the rail is laid, and a spacing member interposed between the joint member and the fixing member, and the joint member and the fixing member each have an insulating property. It is characterized by being formed of hard rubber having.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings. Reference numeral 11 denotes a joint member that holds the damaged portion of the rail 12 from both sides, and one side surface 111
Is formed in the same shape as the neck side surface 121 of the rail 12 along the longitudinal direction, and is fitted and closely fitted to the neck side surface 121. Further, the other side surface 112 of the seam member 11 is formed by bending it in an oblique step shape in the vertical direction.

A fixing member 13 is joined to the side wall 151 of the groove 15 formed in the concrete block 14 on which the rail 12 is laid.
1 is formed in the same shape as the side wall 151.
It is designed to be fitted and closely attached to. Also, the fixing member 1
The other side surface 132 of the seam member 3 is the other side surface 112 of the joint member 11.
When the two surfaces 112 and 132 are opposed to each other, the gap 16 formed therein has a shape like a combination of L-shapes. In the embodiment, the gap 16 formed between the seam member 11 and the fixing member 13 has a shape like a combination of L-shapes. However, the shape is not limited to this and may be an appropriate shape. However, it is not preferable to make it straight because the spacing member 17, which will be described later, may fall off due to vibrations during train running.

Reference numeral 17 denotes a spacing member made of a steel plate material that is interposed in the gap 16, and is formed by being divided into two parts, a lower spacing member 171 and an upper spacing member 172. Although this is divided into two in order to facilitate the insertion work, it goes without saying that they may be formed integrally. It is recommended that the tip end of the spacing member 17 be formed in a wedge shape because the insertion work can be further facilitated.

Reference numeral 18 denotes a concave groove 1 of the concrete block 14.
5 is a filling member that is interposed between the side wall 151 of the concave groove 15 and the fixing member 13 in the rail fastening portion in which the lower half portion 152 of the rail 5 is widened, and is a hard rubber having an insulating property. Is formed by.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a method for attaching the rail 12 of the emergency joint device of the present invention to a damaged portion will be described. First, the seam member 11 is brought into contact with the damaged portion of the rail 12, and then the fixing member 13 is placed at the corresponding position of the concrete block 1.
The side wall 151 of the concave groove 15 of No. 4 is brought into contact with the side wall 151. After that, the spacing member 17 is inserted into the gap 16 formed between the joint member 11 and the fixing member from the side.

In the above embodiment, the seam member 11 is inserted first, but the fixing member 13 may be inserted first. When the damaged portion of the rail 12 is located at the rail fastening portion, the fastening bolt of the portion is removed, the filling member is fitted into the portion, and then the fixing member 13 is installed. Even if the fastening bolts of this portion are removed, there is no problem because the rail 12 is fixed by the fastening bolts on both sides thereof.
Further, it is needless to say that the temporary seam device may be attached either inside the rail or outside the rail.

[0012]

As described above, according to the present invention, the seam member that holds the damaged portion of the rail from both sides, the fixing member that is joined to the side wall of the groove of the concrete block on which the rail is laid, and the seam member. And a fixing member, and a spacing member interposed between the fixing member and the fixing member, and since the joint member and the fixing member are each formed of hard rubber having an insulating property, it is not necessary to use a special electric insulating material. Since the number of points is small and the structure is simple, it can be provided at a low price.

Further, at the time of mounting, the joint member and the fixing member are brought into contact with the damaged portion of the rail and the side wall of the groove of the concrete block, respectively, and the spacing member is inserted into the gap formed between the joint member and the fixing member. You just need to
It is easy and quick to install and does not significantly affect road traffic and train travel.

Further, according to the present invention, in the rail fastening portion where the lower half of the groove of the concrete block is widened, a hard rubber having an insulating property is provided between the side wall of the groove of the concrete block and the fixing member. Since the formed filling member is interposed, it is a practically useful invention that the emergency seam can be surely installed even if the rail of the portion is damaged.
