Description

Rail pad of rails {Rail pad of railroad}

The present invention relates to a rail pad for railroad, and more specifically, a high-strength seal is intersected in a rubber body in a multi-layered manner to increase excessive stretch inhibition and restoring force, and to cushion and vent through a plurality of protrusions protruding from the upper and lower surfaces. The present invention relates to a rail pad for railroad that provides excellent durability, extended service life, and improved function by preventing deformation due to load, impact, and overheating.

In general, a train carrying passengers and cargo moves along a railway track constructed on the ground, and the railway track has a structure in which a sleeper is buried in a gravel layer and rails are installed along the sleeper to ensure durability of the load of the train. Have

The sleepers are mainly using concrete materials in recent years.

Such a railway track has a problem in that noise is frequently generated as well as part breakage due to friction between sleepers of a concrete material and rails.

For this reason, a rubber rail pad is provided between the sleeper made of concrete and the rail.

More specifically, as shown in FIG. 1, the rail pad 3 and the rail 5 may be seated and installed on the concrete sleeper 2, or the base plate 4, the rail pad 3, and the rail 5 may be installed. The seat is installed, but the rail pad and the rail is installed to be fixed at both sides by rail fasteners (7) (7).

The rail pad 3 installed as described above absorbs and absorbs the load and vibration generated in the vertical direction when the train is running, thereby preventing noise and minimizing damage to parts such as sleepers and rails.

However, since the conventional rail pad 3 is simply formed in the form of a rubber plate, there is a problem in that durability is poor because it is easily torn or stretched due to excessive elasticity due to the load or heat of the train.

In addition, in the summer season, the conventional rail pad 3 is easily heated and deformed between the concrete sleeper 2 and the rail 5, thereby shortening durability and easily losing its function as a rail pad. .

Moreover, since the rail pad 3 is easily deformed due to the deformation of the rail pad 3 as described above, the vibration or shock of the train is not sufficiently buffered, so that it is not effective in preventing the damage of the concrete sleepers or the rails, which causes frequent replacement of parts. Had.

The present invention has been invented to solve all the problems of the prior art as described above, by multi-integrating a high-strength seal inside the rubber body in multiple layers to increase excessive stretch inhibition and restoring force, by a plurality of protrusions projecting on the upper and lower surfaces Its purpose is to provide excellent durability, extended service life, and improved function by minimizing deformation due to load, impact, and overheating through buffering and ventilation.

This invention,

Built-in high-strength seal in a multi-layer inside the rubber material body, the high-strength seal located in each layer is installed seated so that the upper and lower layers cross each other,

The protrusions extending in the longitudinal direction of the rail on the upper and lower surfaces of the rubber material body are formed in a plurality of protrusions in the width direction, characterized in that a plurality of protrusions are formed to be spaced apart to form a ventilation path between adjacent protrusions.

The high-strength seal embedded in a multi-layer inside the rubber material body of the present invention is installed so that the upper and lower layers cross each other in the X-shape while seated at 45 ° and 135 °, the protrusions protruding from the upper and lower surfaces of the rubber material body Its feature is that it is configured to be alternately placed in a staggered position.

The present invention is formed so that the high-strength seal cross-embedded in multiple layers inside the rubber body and the plurality of protrusions on the upper and lower sides to be alternately positioned in a staggered position to increase excessive elasticity suppression and restoring force as well as buffering and aeration action By minimizing deformation due to load, impact, and overheating, it has the effect of providing excellent durability, extended service life and improved function.

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

Rail rail pad of the present invention is installed between the concrete sleeper (2) and the rail (5) or between the concrete sleeper (2) and the base plate (4) and the rail (5), respectively, to apply the load or impact applied by the train To buffer.

2 to 4, the high-strength seal 20, such as nylon thread in a multi-layer inside the rubber body 10, as shown in Figure 2 to 4, the high-strength seal 20 located in each layer is up and down It is achieved by seating so that the layers are located cross each other.

At this time, in the case where the thickness of the rubber body 10 is formed in three equal parts, when a large number of high strength seals 20 are installed at 45 °, the high strength seals 20 at a 2/3 thickness position are installed. Is 135 °, so many seats are installed so that the upper and lower layers cross each other in an X-shape.

And when the thickness of the rubber material body 10 is formed in more than 5 equal to the high-strength yarn located in each layer is installed so that the upper and lower layers cross each other X-shaped repeatedly at 45 ° and 135 °.

In addition, the upper and lower surfaces of the rubber material body 10 is formed with a plurality of protrusions 12, 12 'protruding in the width direction extending in the longitudinal direction of the rail, the ventilation path 15 between the adjacent protrusions ( 15 ') to form a plurality of protrusions spaced apart.

At this time, the protrusions 12 and 12 'protruding from the upper and lower surfaces of the rubber material body 10 are configured to be alternately positioned in a mutually staggered position.

In addition, the protrusions 12 and 12 ′ of the rubber material body are preferably round-shaped protrusions as shown in the drawing, but may be formed in various forms such as a ladder shape, and the degree of change of such a simple form is It belongs to the scope of the invention.

As an unexplained reference number, 17 denotes a recess formed opposite to both sides of the rubber material body 10 and formed to grip the rail fastener 7 and the like.

Hereinafter, the operation and operation of the present invention will be described.

First, the rail pad of the present invention is formed by molding a 1/3 thickness of the rubber material body 10, and then installed a large number of high-strength seal 20 to 45 ° on the upper portion, and the rubber material to the 2/3 thickness position again Mold.

And the high-strength seal 20 is first seated on the rubber material body and installed in a large number of high-strength thread to 135 ° to cross the X-shape, and then the rubber material is applied to the upper part to be molded to have a predetermined thickness. .

Of course, two or more of the said high strength seal | stickers 20 can also be installed crosswise.

At this time, the upper and lower surfaces of the rubber material body 10 is formed with a plurality of protrusions 12, 12 'protruding in the width direction extending in the longitudinal direction of the rail.

In this state, the appearance of the rubber material body 10 is to be manufactured by molding in accordance with the rail pad at the time of molding or by cutting to the shape of the rail pad after molding and then rubber coating the cut surface.

The rail pad of the present invention manufactured as described above is installed between the concrete sleepers 2 and the rails 5 or between the concrete sleepers 2 and the base plate 4 and the rails 5 as shown in FIG. 5. will be.

The rail pad of the present invention installed as described above has a high-strength seal 20 such as nylon thread in a multi-layered interior of the rubber body 10, but the upper and lower layers intersect each other in an X-shape so that the load of the train Since suppression of excessive stretch force and increased restoring force due to frictional heat as a whole is provided in a balanced manner, it is effectively preventing a rubber body from being torn or stretched as in the prior art.

In addition, the protrusions 12, 12 'extending in the longitudinal direction of the rail on the upper and lower surfaces of the rubber material body 10 is formed to project a plurality of spaced apart to form the ventilation paths (15, 15') The upper and lower projections 12 and 12 'are alternately positioned in a mutually staggered position, thereby increasing the buffering force against the load of the train as well as through the ventilation paths 15 and 15' in summer.
