And a rail fastening structure in a branching rail using a wire spring brace.

Railroad track dividers are made up of special rails such as crossing rails and tongrels, which determine the direction of travel of the train. When the train passes, centrifugal force acts on the train that swings up and down and swings left and right. By being transmitted from the wheel to the rail, a lateral pressure is generated to push the rail in the branching device laterally. In order to support lateral deformation of the rail due to lateral pressure, in a general branching device, a rail fastening device is used in which a rail brace receiving lateral pressure is arranged on a rail at a position where the lateral pressure is generated.
Also, as a rail fastening device in a branching device, a structure for elastically fastening the rail by a leaf spring or a wire spring has been proposed in order to reduce noise vibration and rail wear and simplify maintenance and inspection work. Yes.

  As a rail fastening device having such a structure, for example, as shown in FIG. 11, a clip locking bracket 61 having a clip insertion hole 610 formed on the floor plate 2 is fixed to the floor plate 2 fixed by welding. The rail brace 60 is placed on the floor plate 2 so that the clip latching fitting 61 is accommodated in the through-hole of the lube 60, and the rear end projection 600 is fitted into the latching recess 20 of the floor plate 2 so that the rail base The movement in the direction away from 40 is prevented. The tip 602 of the rail brace 60 is in contact with the upper abdomen 41 of the basic rail 4 and the vicinity of the L-shaped bent portion 603 is in contact with the upper surface of the rail base 40.

  Then, one end of the wire spring clip 62 is inserted and locked in the clip insertion hole 610 of the clip locking fitting 61, and the other end side of the wire spring clip 62 is deformed against the spring force. The rail brace 60 is pressed and fastened to the clip locking fitting 61 by a wire spring clip 62 by abutting against the central upper surface of the rail brace and the upper surface of the rear projection 600 (Patent Document 1).

An example of an embodiment of a wire spring brace according to the present invention will be described with reference to FIGS. 1, 2, and 3.
The wire spring brace 10 fastens the rail 4 placed on the floor plate 2 and is composed entirely of steel such as SS material, and includes a side rail contact surface 11 and a side rail contact surface. 11 on the side pedestal abutment surface 12 facing the rail 11, the upper inclined surface 13 which is inclined so that the rail arrangement side is at a high position, the first bottom surface 14 in contact with the floor board 2, and the base 4b of the rail 4 And a second bottom surface 15 in contact therewith.
The side rail contact surface 11 and the second bottom surface 15 are connected by a lower inclined surface 16, and the upper inclined surface 13 is connected to an upper surface 18 via an arc surface 17.

The wire spring brace 10 described above is used to fasten the rail 4 laid on the floor plate 2 as shown in FIGS. 3 and 4. FIG. 5 shows an assembled state in which the wire spring brace 10 is fixed to the rail 4 laid on the floor plate 2.
That is, the side pedestal abutment surface 12 of the wire spring brace 10 is brought into contact with the entire side surface 31 of the spring clip mounting pedestal 30 placed and fixed on the floor plate 2 by welding, and the side rail abutment. It arrange | positions so that the contact surface 11 may contact | abut to the abdominal part 4a of the rail 4. FIG.

The upper inclined surface 13 of the wire spring brace 10 is pressed by the lower surface of the spring clip 35 fixed to the spring clip mounting base 30, and the upper inclined surface 13 is inclined so that the rail side is at a high position. The pressure acts on the rail side, and the side rail contact surface 11 of the wire spring brace 10 is securely brought into contact with the abdomen 4 a of the rail 4. The spring clip 35 is formed by forming a spring rigid wire into a substantially elliptical ring shape, and one end side thereof is inserted into a hole 32 provided on the upper side of the spring clip mounting base 30 and fixed, whereby the spring clip 35 The lower surface acts to press the upper inclined surface 13.
Since the abdomen 4a of the rail 4 has a vertical plane regardless of the rail manufacturing tolerance, the side rail abutment surface 11 always contacts the abdomen 4a of the rail 4 in the same state, so that the rail 4 can be securely pressed. Can be included.

  Since the side pedestal contact surface 12 of the wire spring brace 10 is in contact with the entire side surface 31 of the spring clip mounting base 30, the side surface 31 can receive the force received from the rail 4. Further, the force acting in the vertical direction on the upper inclined surface 13 which is a plane inclined surface is applied to the first bottom surface 14 in contact with the floor plate 2 and the second bottom surface 15 in contact with the base portion 4 b of the rail 4, thereby allowing the floor plate 2 to In addition, the wire spring brace 10 is surely pressed against the base portion 4b of the rail 4 so that the small return can be prevented.

FIGS. 6 and 7 show an example of another embodiment of the wire spring brace 10, and the same reference numerals are given to the portions having the same configurations as those in FIGS. 1 and 2, and the description thereof is omitted. Moreover, the rail fastening structure using the brace for wire springs of FIG.6 and FIG.7 is shown in FIG. 8, and the assembly state which fixes the rail 4 by which the brace 10 for wire springs was laid on the floor board 2 is shown in FIG.
In this example, the upper inclined portion 13 of the wire spring brace 10 is formed with a circular gradient in which the center is concave on the rail brace surface with which the spring clip 35 abuts (FIG. 6). The rail brace surface on which the circular gradient is formed has a concave circular gradient of 1/65 (1/50 to 1/100). Specifically, when the length in the longitudinal direction of the wire spring brace 10 is 130 cm and the circular gradient is 1/65, the central portion has a shape recessed by 1 mm.

  A plurality of rail brace surfaces (positions where the spring clip abuts) of the upper inclined portion 13 intersect with the longitudinal direction (longitudinal direction of a spring clip 35 described later) on the rail brace surface on which a circular gradient is formed. A rod-shaped protrusion 19 is formed. The rod-shaped protrusions 19 are configured to have a height of 0.1 to 0.5 mm and a width of 1 to 2 mm at a pitch of 1/5 (1/3 to 1/10) of the length of the wire spring brace, for example. .

By forming a circular gradient whose center is concave on the upper inclined surface 13 of the wire spring brace 10, it is possible to make it difficult for the attached spring clip 35 to deviate from the circular gradient of the rail brace surface.
Further, by forming the rod-shaped protrusion 19 in the arc-shaped gradient, the contact with the lower surface of the spring clip 35 attached to the rail brace surface can be performed at two or more points, and the pressing force from the spring clip 35 is applied to the rail. I can tell the breath side reliably.

  The wire spring brace 10 shown in FIG. 6 and FIG. 7 forms a rod-shaped protrusion 19 by making the rail brace surface with which the spring clip 35 in the upper inclined portion 13 abuts has a circular gradient with respect to FIG. 1 and FIG. However, as shown in FIG. 10, only a circular gradient is formed on the flat upper inclined portion 13 (FIG. 10A) of the wire spring brace 10 of FIGS. 1 and 2 (FIG. 10). 10 (b)), a structure in which only a rod-shaped protrusion is formed on a plane (FIG. 11C), or a structure in which a circular gradient and a rod-shaped protrusion are formed (FIG. 10D) may be used.

According to each wire spring brace 10 (FIGS. 1 and 6) having the above-described structure, the upper inclined surface 13 with which the lower surface of the spring clip 35 abuts is slightly lower from the “rail 4” toward the “spring clip mounting base 30”. When the wire spring brace 10 is transmitted to the spring clip mounting base 30 from the position where the wire spring brace 10 is in contact with the abdomen 4 a of the rail 4, the force applied to the rail 4 acts obliquely downward. In FIG. 3, the pressing force of the spring clip 35 is efficiently suppressed by pressing the position where the action line X and the vertical line Y of “the position where the wire spring brace 10 and the floor plate 2 meet” are pressed by the spring clip 35. It can be transmitted to the floor plate 2 side or the abdomen 4a of the rail 4.
That is, when pressing above the action line X, the dimension of the wire spring brace 10 is increased, and when pressing below the action line X, the brace dimension at the pressing position is reduced, and the portion is deformed, The phenomenon that the brace 10 for wire springs which hits the abdomen 4a from the portion is bent occurs.

  Further, according to the above-described rail fastening structure, both side surfaces (the side rail contact surface 11 and the side base contact surface 12) of the wire spring brace 10 are connected to the abdomen 4a of the rail 4 and the spring clip mounting base 30. Since they are configured to contact each other, the contact surface is positioned on the vertical surface and can be visually confirmed from above or from the side, and the rail 4 of the wire spring brace 10 and the spring clip mounting base 30 It becomes easy to check the tightness of the. As a result, it is possible to prevent work mistakes during installation.
