Technical Field

[0001] The utility model relates to the field of rail pads, and particularly relates to an elastic rail pad. Background Technique

[0002] Rail pads are usually installed on the roadbed of the track, and each rail is equipped with a pad below. Rail pads play a key role in the railway system. They are mainly used to support the rails, distribute the train load, and ensure the stability of the track. The pad reduces the pressure on the roadbed by evenly distributing the weight and prevents the track from deforming.

[0003] At present, the rail pads on the market are of a pure flat plate structure, with a relatively large overall stiffness. After being subjected to pressure, they have poor elasticity, are prone to compressive deformation and have a poor shock absorption effect, resulting in a poor use effect.

[0008] In some embodiments, adjacent two of the elliptical frames are connected through a connecting rod.

[0009] In some embodiments, the elliptical frames, the inner skeleton, the side retaining frames and the pad body are integrally formed.

[0010] In some embodiments, the inner skeleton is in an inverted "U" shape, and through holes are provided on the inner skeleton, and the through holes are arranged corresponding to the through holes.

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope protected by the present invention.

[0024] First Embodiment:

[0025] See Figures 1 - 3As shown in the figure, the present utility model provides an elastic rail tie plate, which includes a tie plate body 1. A through hole 101 for assisting in fixing the spike is provided on the tie plate body 1. The width of the tie plate body 1 corresponds to that of the sleeper. A plurality of elliptical frames 3 are arranged inside the tie plate body 1 in a rectangular array. An inner filling layer 4 is filled inside the elliptical frame 3. The elastic coefficient of the tie plate body 1 is greater than that of the inner filling layer 4. Side retaining frames 102 extending downward are provided on both sides of the width of the tie plate body 1. An inner skeleton 2 is provided between the two side retaining frames 102. When the tie plate body 1 is installed by using the side retaining frames 102, the side retaining frames 102 located on both sides of the width of the sleeper can be used to limit the tie plate body 1, and in cooperation with the through hole 101, the spike and the rail clip can be fixed, so as to fix the tie plate body 1 between the rail and the sleeper. The inner skeleton 2 can support and limit the side retaining frames 102 and the tie plate body 1. When the device is in use, the elliptical frames 3 inside the tie plate body 1 and the inner filling layer 4 inside the elliptical frames 3 form a support for the tie plate body 1, providing a better elastic response for the tie plate body 1, so that when the device is in use, it can more effectively absorb the vibration and impact generated during the train operation. The elastic coefficient of the tie plate body 1 is greater than that of the inner filling layer 4, and the inner filling layer 4 can be wrapped by the tie plate body 1, which can not only reduce the temperature received by the inner filling layer 4 and protect the inner filling layer 4, but also, the inner filling layer 4 has better elasticity, and the vibration influence on the track structure and the buildings along the line can be reduced through the inner filling layer 4, which also helps to reduce the noise generated during the train operation and improve the comfort of passengers. The device can reduce the settlement of the roadbed caused by the track load, so as to maintain the flatness of the track and the driving safety.

[0026] In a preferred embodiment, the elliptical frame 3, the inner skeleton 2, the side retaining frame 102 and the tie plate body 1 are integrally formed.

[0027] The second embodiment is different from the first embodiment in the following features:

[0028] Adjacent two elliptical frames 3 are connected and communicated through a connecting rod 301. The elliptical frame 3 has an elliptical cross-section. In a preferred embodiment, the long end of the elliptical frame 3 is vertically arranged, and the short side of the elliptical frame 3 extends horizontally towards both sides of the length of the tie plate body 1.

[0029] The third embodiment is different from the first embodiment in the following features:

[0030] The inner skeleton 2 is in an inverted "U" shape. The inner skeleton 2 is provided with a through hole 201, and the through hole 201 is correspondingly arranged with the through hole 101. The inner skeleton 2 is provided with a material passing hole 202. By using the material passing hole 202 and the through hole 201, the inner skeleton 2 can be formed and arranged in the base plate body 1 and the side baffle 102, improving the connection stability between the side baffle 102 and the base plate body 1. The material passing hole 202 helps to form a more firm combination between the base plate body 1 and the inner skeleton 2, improving the stability of the overall structure, ensuring that the base plate body 1 and the side baffle 102 can be evenly distributed on the outer side of the inner skeleton 2, and enhancing wear resistance and service life.

[0031] Furthermore, the material of the base plate body 1 is thermoplastic polyester elastomer, and the inner filling layer 4 is thermoplastic polyurethane elastomer. The base plate body 1 can form a wrapping of the inner filling layer 4. Through the excellent wear resistance of the thermoplastic polyester elastomer, the wrapping of the inner thermoplastic polyurethane elastomer can be realized, and by using the flexibility and elasticity of the thermoplastic polyurethane elastomer, it helps to improve the elasticity of the outer thermoplastic polyester elastomer and enhance the overall use experience of the device.

[0032] In a preferred embodiment, the bottom surface of the base plate body 1 is provided with anti-slip protrusions, which play an anti-slip and fixing effect, and both sides of the base plate body 1 and the top surface of the side baffle 102 are inclined.

[0033] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
