Description

Gravel scattering prevention mat of gravel road track {A MAT FOR PREVENTING FLYING BALLAST IN THE RAIL ROAD}

The present invention lays an elastic mat with holes formed between the gravel and the sleepers, and prevents the gravel embedded on the railroad tracks of high-speed trains from flying at high speeds, preventing damage to the body or track, The present invention relates to a gravel scattering prevention mat of a railroad track for preventing splashing of gravel.

In general, the railroad that is the way the train travels, as shown in FIG. 1, the sleepers 12 are regularly arranged on the upper surface of the gravel 11 which rises a certain height above the ground, and the train wheels are arranged on the top of the sleepers 12. A line 13 is formed to engage and move.

That is, the gravel 11 is buried on a general railroad track, the gravel 11 tends to scatter due to the impact of the movement of the railway vehicle.

In order to solve this problem, in the past, the gravel blowing phenomenon was prevented to some extent through the periodic compacting of the gravel, but the gravel compacting effect was impeded when the vehicle was repeatedly operated, and the gravel was blown by the impact of the object away from the vehicle. It could not be prevented.

As another method to solve this problem, there is a method of applying synthetic resin to the gravel to fix the surface to prevent the flying of the gravel, but the phenomenon of falling of the gravel stuck due to the vibration caused by the continuous running of the vehicle occurs, There is a hassle that needs to be reapplied after the work for the management of gravel periodically, and there was no preventive effect against the flying of gravel by the impact of the object away from the vehicle.

That is, the danger that can be caused by the operation of the vehicle is that the gravel is caused by objects falling from the vehicle (for example, snowballs in the snow due to snow accumulation in winter), rather than by the gravel caused by the wind generated under the vehicle at high speed. The splashing problem is bigger, but there is no real workaround.

On the other hand, in recent years, high-speed railway is commercialized to drive the railroad at a higher speed.

The maximum wind speed generated by the high-speed driving of such a high-speed railway vehicle varies depending on the structure of the vehicle and the structure of the sleeper, but the speed of the vehicle is about 300 km / hr. Since the wind speed is about 30 ~ 50m / s, the gravel having a light weight and flat structure is particularly affected and blown out.

In particular, when snow comes in winter, snow and ice accumulate on the vehicle, and fall to the ground due to wind pressure change or temperature increase, which is a critical load or an external factor.

The impact force generated at this time is considerable, and as the gravel blown by the impact collides with the lower part of the vehicle, a larger kinetic energy increases, and a chain phenomenon occurs in which the gravel is blown secondarily by colliding with the gravel laid on the road again.

Due to the above phenomenon, the blown gravel can cause great damage to the lower part of the vehicle, and if the gravel is broken into the history section, it may pose a danger to the person.

Therefore, the present invention was devised to solve the above problems, the present proposal is to install a mat on the top of the gravel of the rail road to prevent the flying of the gravel caused by the wind caused by the high-speed operation of the railroad car, the vehicle running It aims not only to prevent the splashing of gravel by falling objects but also to maintain the characteristics of the gravel track, not to block the flow of air or water.

The present invention for achieving the above object is a sleeper is arranged on the gravel gravel, in the railroad track is seated on the top of the sleeper,

In order to prevent the scattering of the gravel gravel, it provides a gravel scattering prevention mat of the gravel ballast of the elastic material, characterized in that installed between the donor gal and sleepers.

Since the mat covers the gravel embedded on the railroad tracks, even if the railroad vehicle runs at high speed, the mat not only prevents the gravel from scattering, but also prevents the gravel from being damaged.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only, the same parts as in the conventional configuration using the same reference numerals or names.

Figure 2 is a perspective view showing a mat according to the present invention, Figure 3 is a cross-sectional view A-A of Figure 2, Figure 4 is a view showing a state in which the mat of Figure 2 is applied to the railroad tracks.

And, Figure 5 is an embodiment of the use of the coupling strap according to the present invention.

As shown, the sleeper 12 is arranged on the top of the gravel 11, the track 13 is seated on the top of the sleeper 12, between the gravel 11 and the sleeper 12 The mat 20 according to the present invention is embedded.

The mat 20 is preferably molded of a rubber having elasticity and flexibility or a material having a corresponding property so as to absorb and disperse the impact of the falling object and have adhesion when installed on the gravel 11. .

In this case, a plurality of holes 21 are formed in the mat 20, and the holes 21 have an angled shape in order to increase the adhesion with the gravel 11 to prevent the gravel from flowing down. In order to prevent the gravel from falling out of the mat, the cross section of the hole 21 becomes narrower toward the top or preferably has a concave portion at the middle of the cross section (see FIG. 3).

That is, the hole 21 may have various angular shapes, such as a square or a hexagon, and one such angular shape may be regularly formed, or two or more may be selectively mixed.

On the other hand, the mat 20 and the side of the adjacent mat 20 is preferably connected to each other through a connecting member 31, such a connecting member 31 is a stainless band is suitable.

And, on the mat 20, it is preferable that a coupling strap 22 is formed to tie the mat and the mat under the sleeper 12 in order to hardly fix the sleeper 12 (see FIG. 5).

In addition, the fixing member 32 for fixing the mat 20 is connected to the mat 20 and the stainless band to be embedded in the gravel 11, the fixing member 32 as an anchor (anchor) or Various other members can be used. In one embodiment, the construction of the anchor is preferably fixed once per 10 mats.

The action and effect of the present invention made of the above structure is as follows.

After placing the sleepers 12 regularly on the crest 11 of the railroad tracks, and after the track 13 is disposed on the top of the sleepers 12, a plurality of mats 20 according to the present invention between the sleepers Laying, fixing using the connection member 31 and the coupling strap 22, the fixing member (32).

At this time, the mat 20 and the mat 20 are continuously connected to each other through the connecting member 31 is installed on the rail, bar coupling 12 formed on the mat 20 under the sleeper 12 As a result of the binding, the mating force between the mat and the mat is improved, and the mating force between the mat 20 and the gravel 11 is improved through the fixing member 32.

In addition, since the mat 20 is seated on the gravel 11, the gravel 11 is not blown due to the load of the mat 20 itself, and the gravel 11 has a vibration preventing effect when driving a railway vehicle, which is a unique function. Will be maintained.

On the other hand, since the hole 21 formed in the mat 20 has an angular shape, it increases adhesion to the gravel 11 and prevents the flow of the gravel 11 while preventing the flow of air or water, This results in a longer cycle for compaction work of gravel 11, reducing the maintenance burden of the railroad tracks.

In addition, the cross section of the hole on the mat has a structure that narrows toward the upper portion, or there is a concave portion can effectively prevent the gravel from coming out of the mat.

Therefore, except for the sleeper part of the rail, the mat wraps the gravel which can be affected by the impact or speed as a whole, and continuously connects the mat and the mat, thereby preventing the flying of the gravel due to the driving of the vehicle.

In particular, since the gravel that can be blown due to the wind speed generated by the vehicle traveling at high speed is entirely covered by a mat having several holes, the gravel is prevented from being blown to prevent damage to the lower part of the vehicle or the railway.

In addition, even if the object falling from the vehicle falls on the gravel phase, the elastic mat having a hole disperses and absorbs the impact around, thereby preventing the gravel from flying and preventing the gravel from breaking.

As described above, the gravel scattering mat of the railroad track according to the present invention is installed between the sleeper and the gravel elastic mat, absorbing the impact of the falling object from the railroad car to prevent the movement of the gravel, compacting the gravel It has the advantage of reducing the maintenance cost of the railroad by extending the cycle.

In addition, since the mat covers the gravel, there is an effect of preventing the scattering of the gravel.

In addition, it prevents the scattering of gravel, but does not block the flow of air or water, such as maintaining the characteristics of the existing gravel track.
