The present invention relates to an elastic fastener for use in a rail branch, which in particular, ensures a strong fastening force on the inner bottom of the base rail of the point part and the guard part to stabilize the track and when the train passes the rail branch at high speed. The present invention relates to a U-shaped rail elastic fastener capable of improving ride comfort and driving safety while reducing fluctuations in trains.

In general, when a high-speed train passes through the branch of the track, shock and noise occur with severe fluctuations, and one of the important reasons is the insufficient fastening force of the basic rail.

Therefore, there is an urgent need for fasteners capable of securing the same fastening force as the outer side even inside the basic rail of the point part and the guard part in the tap-off.

Accordingly, the present invention has been made in view of the above-mentioned problems and circumstances, and an object thereof is that the point part and the guard part in the railroad branch branch are completely elastically fastened, thereby simplifying the installation and maintenance by simplifying the parts and simplifying the parts. Of course, the speed of the train at the branch of the rail and the noise and up, down, left and right fluctuations greatly improved when passing the train to improve the ride comfort, and the rail fasteners are secured enough to extend the life of the rail and sleepers An elastic fastener is provided.

As a technical means for achieving the above object, the present invention, both sides of the slide plate, which is a rail elastic fastener protrudes the pressing jaw, the rear portion is formed with a clip support, is installed in the plate to optimize the one end of the rail bottom It is composed of an elastic clip bent in a "U" shape to support with the elastic force of.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a slide plate, which is a rail-elastic fastener according to the present invention, and FIG. 2 is a longitudinal cross-sectional view of a state in which a point portion rail-elastic fastener is installed. A welding shoulder 9 for fastening an elastic clip (pentrol clip) 8 supporting the bottom of the other end of the rail is protruded and installed at one end of the plate 1, and the slide plate is provided. U-shaped elastic clip 20 that is elastically bound in (1) is provided.

In addition, the pressing jaw (3a) (3b) protrudes on both sides of the slide plate (1) in the transverse direction, the rear of the clip support (4) is provided.

As shown in FIG. 2, the U-shaped elastic clip 20 has a bent portion 21 formed at a constant angle at an end portion to support the bottom 7 side surface and the inclined surface of the rail 6.

On the other hand, Figure 3 is a view showing the rail elastic fasteners of the guard portion, the H-type guard 30 is coupled to the bolt 33 and the nut 34 through the guard support 31 and the adjustment plate 32, It is made of a configuration that the elastic clip is installed below the guard support (31).

As shown in FIGS. 1 and 2, the rail-elastic fastener of the present invention configured as described above has one side of the sliding surface 10 in which one side of the bottom portion 7 of the rail 6 is integrated with the plate 1. It is inclined at an angle of about 40 degrees, and one end is fixed to the hanging jaw, and the bottom of the “U” shaped elastic clip 20 is fastened to the clip support 4 of the rear side of the sliding surface 10 and protrudes on both sides in the lateral direction. Both inclined portions 21 of the elastic clip 20 are pressed through the pressed jaw (3a) (3b) by pressing the bottom (7) of the rail (6) with elastic force to support it.

In addition, the welding shoulder 9 is installed at one side of the plate 1 of the rail elastic fastener in a state where one side of the bottom portion 7 of the rail 6 is fixed by the elastic clip 20 of the rail elastic fastener. By fastening the clip (pentrol clip) 8 to the bottom of the multi-side of the rail 6, the rail 6 is coupled to the bottom of the plate 7 in a rigid state with both sides of the bottom 7 above. Can be fixed).

3 is a longitudinal cross-sectional view of a rail elastic fastener installed in the rail guard unit, and the guard support 31 and the guard rail 35 provided on the plate 1 are disposed through the adjustment plate 32. 33) and the nut 34, to support and secure the other bottom of the rail 35 with an elastic clip (pend roll clip) 8 through a welding shoulder 9 located at one end of the plate 1; By inserting the U-shaped elastic clip 20 under the guard rail 35 of the guard support 31 in the state of making a state, the bottom portion 37 of the rail 36 is fixedly coupled to the train at the branch of the railway line, the left Trains running at udon and high speeds can be guided to the basic rail without derailing.

In addition, according to the wear of the wheel flangeway width, it is possible to appropriately adjust the gap by adjusting the control plate 32 between the guard rails 35 of the guard rail support 31.

According to the rail-elastic fastener according to the present invention as described above, by the structure of the slide plate and the guard plate provided in the point portion and the guard portion of the rail as described above, the line due to the fully elastic fastening of the point portion and the guard portion in the branch portion It is easy to install and repair with stability and simplification of parts, as well as to extend the maintenance cycle, and improves the stability of the train according to the speed of the train, and greatly improves the riding comfort by greatly improving the noise and fluctuation of up, down, left and right when passing the train. Has an excellent effect.
