  As shown in FIG. 5, the distance between the center C of the washer boss 152 formed on the rotary washer 150 and the inner peripheral wall surface 153a for adjusting the gauge is about 0 stepwise for each predetermined rotation angle of the rotary washer 150. Set to increase or decrease by 2 mm.

Next, the adjustment method between the rails of the rail R is demonstrated based on FIG.
First, FIG. 6A shows a state in which the rotary washer 150 is installed on the tie plate 110 so that the inner peripheral wall surface 153aA for adjusting the gauge and the tie plate fixing bolt 140 are in contact with each other.

6B, the rotary washer 150 is rotated 90 ° in the clockwise direction in the drawing from the state of FIG. 6A, and the inner peripheral wall surface 153aB for adjusting the gauge and the tie plate fixing bolt 140 are brought into contact with each other. Shows the state.
At this time, the distance from the center C of the washer boss 152 to the inner peripheral wall surface 153aB for adjusting the gauge is set to be approximately 0.6 mm shorter than the distance from the center C of the washer boss 152 to the inner peripheral wall surface 153aA for adjusting the gauge. Therefore, the tie plate 110 moves about 0.6 mm toward the left side of the drawing.

6C, the rotary washer 150 is rotated 90 ° in the clockwise direction in the drawing from the state of FIG. 6B, and the inner peripheral wall surface 153aC for adjusting the gauge and the tie plate fixing bolt 140 are brought into contact with each other. Shows the state.
At this time, the distance from the center C of the washer boss portion 152 of the inner peripheral wall surface 153aC for adjusting the gauge is set to be about 0.6 mm shorter than the distance from the center C of the washer boss portion 152 of the inner peripheral wall surface 153aB for adjusting the gauge. Therefore, the tie plate 110 moves about 0.6 mm toward the left side of the drawing, and moves about 1.2 mm in total from the state shown in FIG.

6D, the rotary washer 150 is rotated 90 ° in the clockwise direction of the drawing from the state of FIG. 6C, and the inner peripheral wall surface 153aD for adjusting the gauge is brought into contact with the tie plate fixing bolt 140. Shows the state.
At this time, the distance from the center C of the washer boss 152 to the inner peripheral wall surface 153aD for adjusting the gauge is set to be approximately 0.6 mm shorter than the distance from the center C of the washer boss 152 to the inner peripheral wall surface 153aC for adjusting the gauge. Therefore, the tie plate 110 moves about 0.6 mm toward the left side of the drawing, and moves about 1.8 mm in total from the state shown in FIG.

In the rail fastening adjustment unit 100 of this embodiment obtained in this way, the gauge adjusting means 130 includes a tie plate fixing bolt 140 and a rotary washer 150, and the rotary washer 150 includes a washer flange 151 and a washer. It has a boss 152 and a washer through hole 153.
Therefore, by changing the rotation angle of the rotary washer 150 with respect to the tie plate 110, the washer interposed between the inner peripheral surface of the plate through hole 111 formed in the tie plate 110 and the outer peripheral surface of the tie plate fixing bolt 140. Since the thickness of the boss part 152 in the gauge direction changes, the position of the tie plate 110 in the gauge direction can be adjusted to easily adjust the gauge D of the pair of left and right rails R, and the rotary washer 150 is formed. At this time, it is only necessary to change the thickness of the washer boss portion 152 for each rotation angle of the rotary washer 150. Since the molding process is not complicated, the rotary washer is made of cast iron or the like that is difficult to perform fine processing. Even in the case of forming 150, a fine difference is provided in the thickness of the washer boss portion 152 for each rotation angle, and the rail adjustment of the rail R can be achieved at a fine adjustment interval.

  And the thickness to the gauge direction of the washer boss part 152 is arbitrarily set for every rotation angle of the rotary washer 150 by forming the inner circumference surface of the washer through-hole 153 with a plurality of gauge adjusting inner circumferential wall surfaces 153a. Therefore, the adjustment operation between the rails R can be achieved more easily and precisely.

The washer flange portion 151 has a plurality of scale projections 151 a that are locked by a stopper portion 112 projecting from the tie plate 110 to position and display the rotation angle of the rotary washer 150 with respect to the tie plate 110.
Therefore, not only the rotary washer 150 is positioned with respect to the tie plate 110 at a predetermined rotation angle, but also the operator can determine the rotation angle of the rotary washer 150 through the scale projection 151a. Work can be achieved more easily.

The inner peripheral wall surface 153a for adjusting the gauge is orthogonal to the gauge direction for each rotation angle of the rotary washer 150 positioned by the scale protrusion 151a.
Accordingly, since the tie plate fixing bolt 140 is prevented from skidding on the gauge adjusting inner peripheral wall surface 153a, the gauge D of the rail R can be adjusted more accurately.

The distance between the center C of the washer boss 152 and the inner circumferential wall surface 153 a for adjusting the gauge is set so as to increase or decrease in steps for each predetermined rotation angle of the rotary washer 150.
Therefore, since the fine adjustment work of the gauge D by the worker is facilitated, the effect of the gauge adjustment work can be achieved more easily at the work site.

Next, a rail fastening adjustment unit 200 that can adjust the horizontal position according to the second embodiment of the present invention will be described with reference to FIGS.
Here, since the configuration other than the tie plate 210 in the rail fastening adjustment unit 200 according to the second embodiment of the present invention is exactly the same as that of the rail fastening adjustment unit 100 according to the first embodiment described above, the configuration of the first embodiment. The description of the configuration other than the tie plate 210 will be omitted by replacing the specification relating to the rail fastening adjustment unit 100 and the reference numerals in the 100s shown in FIGS. 1 to 6 with the reference numerals in the 200s.

Therefore, a specific form of the tie plate 210, which is the most characteristic feature of the rail fastening adjustment unit 200 of this embodiment, will be described in detail with reference to FIGS.
7 to 9, the tie plate 210 includes a tie plate main body 213 that grips the rail R from above, and a rotary washer 250 installed on the tie plate main body 213 with respect to the tie plate main body 213. And a saw-toothed attachment 214 for adjusting the position in the gauge direction.

  As shown in FIGS. 7 to 9, the tie plate main body 213 includes a main body side serrated engagement portion 213a that engages with an attachment side serrated engagement portion 214a of a serrated attachment 214 described later, and a tie plate fixing bolt. The main body side plate through hole 213b through which 240 is inserted, and a rail positioning protrusion 215 that protrudes from the upper surface and positions the rail R in the gauge direction.

  As shown in FIGS. 7 to 9, the sawtooth attachment 214 includes a plate through hole 211 into which the washer boss portion 252 of the rotary washer 250 is fitted, and a scale protrusion 251 a formed in the washer flange portion 251 of the rotary washer 250. A stopper part 212 that engages with the stopper and positions the rotation angle of the rotary washer 250, and an attachment side that engages with a main body side sawtooth engaging part 213a formed on the upper surface of the tie plate main body 213 in the gauge direction. And a serrated engaging portion 214a.

  The pitch P between the crests of the main body side serrated engaging portion 213a and the attachment side serrated engaging portion 214a is set to about 4 mm, that is, the gauge adjustment inner adjacent in the circumferential direction of the washer through hole 253 is set. The difference in distance from the center C of the washer boss portion 252 between the peripheral wall surfaces 253a (about 0.2 mm in this embodiment) is a peak portion of the attachment-side sawtooth engaging portion 214a formed on the sawtooth attachment 214. It is set smaller than the pitch P between them.

In the rail fastening adjustment unit 200 of this embodiment obtained in this way, the tie plate 210 is composed of the tie plate body 213 and the sawtooth attachment 214, and the sawtooth attachment 214 is the attachment-side serrated engagement portion 214a. And a plate through-hole 211.
Therefore, since the position in the gauge direction of the tie plate main body 213 with respect to the rail support S can be adjusted by changing the position in the gauge direction of the saw-toothed attachment 214 with respect to the tie plate main body 213, the rotary washer 250 is used. It is possible to arbitrarily use the gauge adjustment and the orbit adjustment using the saw-toothed attachment 214 depending on the situation, and a simpler and more precise gauge adjustment can be achieved.

Further, the difference in distance from the center C of the washer boss portion 252 between the inner peripheral wall surfaces 253a for adjusting the gauge between adjacent ones along the circumferential direction of the washer through hole 253 is a sawtooth. The pitch is set to be smaller than the pitch P (about 4 mm in this embodiment) between the crests of the attachment-side serrated engagement portion 214a formed on the attachment 214.
Therefore, since it is possible to perform a large gap adjustment with the sawtooth attachment 214 and a small gap adjustment with the rotary washer 250, it is possible to adjust the gap with a sawtooth according to the required adjustment interval. The attachment 214 and the rotary washer 250 can be arbitrarily used to reduce the work load of the gauge adjustment, and since the sawtooth attachment 214 takes charge of the adjustment of the gauge with a large interval as described above, the adjacent inner circumference for the gauge adjustment The difference in the distance from the center C of the washer boss portion 252 between the wall surfaces 253a can be set much smaller, and more precise adjustment of the gauge can be achieved.
