The present invention relates to a buffer barrier membrane installed at an end point of a track to be used to completely stop a low-speed railway vehicle. More particularly, the present invention relates to an impact force through expansion of a wedge portion during a light collision of a railway vehicle at low speed. And a shock absorber for absorbing the oil and a friction material for stopping the railway vehicle through friction with the rail due to the light collision, respectively, are installed at the upper and lower ends of the barrier film body, thereby maintaining mechanical maintenance compared to the conventional shock absorber using hydraulic pressure. It is easy to use, and in particular, it is applied to a railway friction buffer blocker (hereinafter referred to as a buffer blocker), which makes it possible to lower the price of expensive products by applying a conventional hydraulic shock absorber and an expensive friction material at low cost by applying a general low-cost friction material. It is about.

In general, a buffer buffer barrier for railway is a device installed at the end of the track used to completely stop the low-speed railway vehicle is stopped, divided into a fixed and a friction type, where the fixed buffer barrier is a It is provided with a shock absorbing member for absorbing the impact force in the light collision, the structure is completely fixed to the bottom of the track without friction movement on the track, domestic utility model registration No. 0316394 belongs to this.

In addition, the friction buffer block is provided with a friction member for absorbing the impact force in the event of a light collision of the railroad car, the friction material is installed at the lower end in contact with the rail through the frictional action with the rail due to the impact of the rail car is stopped As a structure, US Pat. No. 5,865,122 belongs here.

Among the fixed buffer barrier membranes, the impact force is primarily absorbed through the shock absorbing member during a light collision of a railway vehicle, but the shock force is absorbed by the shock absorbing member (buffer force) because the fixed buffer barrier membrane is fixed to the bottom of the track. If larger, the buffer member does not absorb it and eventually becomes the same as a state in which the railway vehicle collides with the fixed wall, and the collision of the railway vehicle is damaged, or the fixed buffer barrier is broken.

In addition, in the case of the fixed buffer barrier membrane, the shock absorbing member is configured to be hydraulic in order to increase the absorbing force of the impact force in the light collision of the railway vehicle, but this is not suitable for the seasonal factors, and in particular, there is a problem in that oil leakage and maintenance are very difficult.

In the friction buffer block, the shock absorbing member that absorbs the impact force at the time of the light collision of the railway vehicle is used as the hydraulic compression cylinder that is the same as the buffer member structure of the fixed buffer block (No. 0316394). As in the fixed buffer barrier, there is a problem in that leakage and maintenance are difficult.

Moreover, in the case of the friction buffer block, a friction material was installed at the bottom of the buffer block to stop the railway vehicle through friction with the rail according to the light collision with the hydraulic shock absorber. The shock absorber is primarily absorbed by the hydraulic shock absorber during the collision of the vehicle, and the cushioning barrier is not instantly fixed to the rail by the frictional force applied between the rail and the friction material installed at the bottom of the buffer barrier membrane, and the cushioning barrier slides. The product cost is high because the railroad vehicle must be stopped by the friction between the friction material and the rail, and the overall product cost of the frictional shock absorbing membrane is also increased by applying the hydraulic shock absorber together with the expensive friction material. Economical to buy at a high price There was also a problem that the loss of phosphorus is increased.

In addition, the frictional force is concentrated on the friction material side of the rear part contacting the rail while the front portion colliding with the railway vehicle is lifted by the impact force when the vehicle collides with the railway vehicle. In addition to the problem, there is a problem that the replacement cycle of the friction material is also shortened, such as the need to frequently replace with a new friction material when uneven wear occurs in the friction material as described above.

The present invention has been made in order to solve the above problems, the shock absorber for absorbing the impact force through the expansion action by the wedge portion during the light collision of the railway vehicle at low speed, and the friction between the rail due to the light collision By installing and configuring the friction material to stop the railway vehicle through the operation, respectively, the upper and lower ends of the blocking film body, it is very easy to maintain by mechanical compared to the conventional shock absorber using hydraulic pressure, in particular, the low-cost friction material with the mechanical shock absorber The purpose of the present invention is to reduce the cost of expensive products by applying a conventional hydraulic shock absorber and an expensive friction material as a buffer barrier is applied.

In the buffer device of the present invention, the shock absorber of the present invention is configured to absorb impact force through expansion by a wedge, which is easier to maintain than a conventional shock absorber using hydraulic pressure. It also has the effect of reducing costs.

In addition, as described above, when the low speed railway vehicle collides with the buffer barrier membrane, the shock absorber absorbs the impact force of the shock absorber and friction action by the friction material, that is, the shock barrier membrane due to the collision with the railway vehicle slides and acts on the head of the rail from the friction member. By making the frictional force act uniformly on the entire friction material, one side of the buffer barrier membrane is lifted by the impact force when the vehicle collides with the conventional railway vehicle, and the frictional force is concentrated on the friction material side in contact with the rail, thereby preventing the friction material from being unevenly worn.

As the cushioning barrier film 1 slides together, frictional force acting on the head of the rail R from the friction material 35 is uniformly applied to the entire friction material 35, thereby preventing uneven wear of the friction material 35 as in the prior art. In addition, it is a very effective invention such that the replacement cycle of the friction material 35 can be increased.

As described above, the above-described embodiment is described with respect to the most preferred example of the present invention, but is not limited to the above embodiment, and it is apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention. will be.

The buffer barrier membrane of the present invention is a shock absorber that absorbs the impact force through expansion of the wedge portion during a light collision of the railway vehicle at a low speed, and the railroad vehicle is stopped by the friction action between the rail by the light collision By installing the friction material on the upper and lower ends of the barrier membrane body, the maintenance by mechanical is much easier than the conventional shock absorber using hydraulic pressure, and in particular, by applying a low-cost friction material with the mechanical shock absorber to form a shock absorbing barrier film, There is an excellent effect of lowering the price of expensive products by applying hydraulic shock absorbers and expensive friction materials.

In the buffer device of the present invention, the shock absorber of the present invention is configured to absorb impact force through expansion by a wedge, which is easier to maintain than a conventional shock absorber using hydraulic pressure. It also has the effect of reducing costs.

In addition, as described above, when the low speed railway vehicle collides with the buffer barrier membrane, the shock absorber absorbs the impact force of the shock absorber and friction action by the friction material, that is, the shock barrier membrane due to the collision with the railway vehicle slides and acts on the head of the rail from the friction member. Since the frictional force acts uniformly on the entire friction material, one side of the buffer barrier membrane is lifted by the impact force when the vehicle collides with the conventional railway vehicle, and the frictional force is concentrated on the friction material in contact with the rail, thereby preventing the friction material from being worn out as a whole. At the same time, there is also an effect that can lengthen the replacement cycle of the friction material.
