Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail fastening device for widening the gauge.

[0002]

[Prior art]

 FIG. 7 shows a conventional rail fastening structure in which a spring bearing stand d is mounted on a recessed seating surface c for mounting a rail b provided on a concrete sleeper a, and a plate mounted on the spring bearing stand d. The rail b is fastened to the sleeper a by screwing a rail fastening bolt f penetrating the spring e to an embedding plug g embedded in the sleeper a.

In the figure, h is a washer and i is a track pad.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional structure, it is possible to make fine adjustments in the left and right directions of the rail by replacing the slide leaf springs of the spring cradle. However, the narrow gauge with a gauge of 1067 mm is expanded to a standard gauge with a gauge of 1435 mm. The construction required a conversion for each rail support, and the construction was a major undertaking.

The present invention has been proposed in view of the above problems of the prior art. The purpose of the present invention is to simplify the gauge widening work that requires conversion for each rail support body and save labor. Therefore, it is an object to provide a rail fastening device for widening the gauge, which saves the construction cost.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the rail widening rail fastening device according to the present invention is a rail support having a wide recessed seating surface capable of widening the rail having a predetermined inclination angle in the rail stationary portion along the rail longitudinal direction. A rail embedding center embedding plug embedded in the widthwise center of the recessed seat surface of the sleeper and rails embedded on the left and right of the screw embedding plug or a temporary shoulder block fastening side embedding plug. A rail or a temporary shoulder block fastening member screwed to each of the embedding plugs.

According to a second aspect of the present invention, a rail is arranged in place of the temporary shoulder block so that a four-wire track is formed.

[0008]

[Action]

 As described above, the rail tightening device for widening the gauge according to the present invention includes the central recessed plug on the wide recessed seating surface provided on the rail support, and the left and right recessed plugs. Two embedding plugs are buried, one outside plug is used for temporary shoulder block tightening before widening, and two inside plugs are used for rail tightening, At the time of widening the gauge, move the temporary shoulder block on the outside before widening the gauge to the inner side, screw it into the embedding plug on the inside through the fastening member, tighten it, and tighten the rail embedding plug in the center as it is. The embedding plug for fastening the temporary shoulder block before widening the gauge is screwed and tightened through the fastening member for the layout fastening together with the central embedding plug to increase the rail center spacing. It moves only by minutes.

According to the invention of claim 2, a rail is arranged in the widened portion instead of the temporary shoulder block, and the rail is fastened to the embedded plug by a rail fastening member, so that it can be applied to a four-wire track. You can

【Example】

 The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 denotes a rail support made of concrete sleepers or the like, and is provided with a wide recessed seating surface 1a which can be widened and has a predetermined inclination angle in the longitudinal direction of the rail 2.

[0013] Embedded plugs 3 for fastening a rail are embedded in the center of the recessed seating surface 1a in the width direction, and embedded rails or temporary shoulder blocks for fastening a shoulder block are equally spaced on the left and right sides of the embedded plug 3. 3'and 3 "are buried. Before widening, therefore, as shown in FIGS. 1 and 4, a rail fastening screwed to the embedding plug 3 in the center and the embedding plug 3" on the right side thereof. The rail 2 is fastened to the rail support 1 via bolts 4 and leaf springs 5. In the figure, 6 is a track pad, 7 is a spring holder, and 8 is a washer.

Reference numeral 9 denotes a temporary shoulder block, which is screwed and tightened to the left embedding plug 3 ′ via the bolt 4, and a plate on the left side of the rail 2 is attached by a spring pedestal 7 arranged at the inner end of the block. A spring 5 is supported. When the gauge is widened, the temporary shoulder block 9 is removed as shown in FIGS. 2 and 5, and the left side embedding plug 3'for fastening the block 9 and the central embedding plug 3 are screwed together. The rail 2 is fastened by the rail fastening bolt 4 which is fixed, and the temporary shoulder block 9 is fastened by the rail fastening bolt 4 screwed to the embedding plug 3 ″ on the right side, and is arranged at the left end of the block 9. By supporting the leaf springs 5 by the pedestal 7 thus formed, the rail track 1 is widened without converting the rail support 1.

Further, as shown in FIGS. 3 and 6, by arranging the rail 2 instead of the temporary shoulder block 9 in the widened portion and fastening it by a normal rail fastening device, it is possible to cope with a four-wire structure. Is.

[0014]

[Effect of device]

 According to the present invention, as described above, the rail mounting central embedding plug is embedded in the wide concave seating surface provided on the rail support at the center of the seating surface in the width direction, and the left and right sides of the embedding plug are provided. Rails or temporary shoulder blocks are fastened by embedding side embedding plugs for fastening rails or temporary shoulder blocks, and by fastening rails or temporary shoulder blocks to the embedding plugs at the center and the embedding plugs on the left and right of the center embedding plug. Without changing the whole body, the same rail support can be used to widen the track, and it is possible to share the members such as embedded plugs, which simplifies the construction work and saves the construction cost.

According to a second aspect of the present invention, a rail is arranged in place of the temporary shoulder block, and a four-rail type track is made possible with the same rail support member.
