Description

Technical Field

[0001] The utility model relates to the field of track vibration reduction, in particular to a rubber pad with an added hydraulic shock absorber. Background Art

[0002] Rail transport plays a vital role in the modern transportation system, but it is accompanied by noise and vibration issues that can have adverse effects on nearby communities and the environment. When trains pass over rail tracks, they generate vibrations and noise that can cause structural fatigue, environmental pollution, and affect the quality of life of residents along the line.

[0003] Traditionally, vibration damping pads are widely used in railway track systems to reduce the transmission of vibration and noise. These traditional vibration damping pads are usually made of rubber or elastic materials to support the track structure and reduce the vibration of trains during operation. However, existing single-material vibration damping pads still have some limitations, such as low vibration and noise reduction efficiency, poor durability, high maintenance cost, easy breakage of vibration damping pads, and uncontrollable stiffness.

[0004] In addition, some train track systems require more advanced and effective vibration and noise reduction solutions to meet the requirements of high-speed trains, heavy-duty trucks and urban rail transit. These systems require more advanced vibration and noise reduction technologies to ensure that the track structure itself has a good vibration and noise reduction effect while reducing adverse effects on the surrounding environment and nearby residents. Utility Model Content

[0005] The main purpose of the utility model is to provide a rubber pad with an additional hydraulic shock absorber, which can achieve a better vibration reduction effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a rubber pad with an additional hydraulic shock absorber, comprising:

[0007] Rubber pad body;

[0008] A plurality of rubber protrusions are arranged on the upper surface of the rubber pad body, each rubber protrusion is arranged vertically, and the rubber protrusions are arranged in multiple rows, and the rows are arranged at equal intervals, and the rubber protrusions in each row are arranged at equal intervals;

[0009] A plurality of hydraulic shock absorbers, each of which is arranged vertically, with the lower end arranged on the upper surface of the rubber pad body, the hydraulic shock absorbers are arranged in multiple rows, and the rows are arranged at equal intervals, and the hydraulic shock absorbers in each row are arranged at equal intervals;

[0010] The upper composite material rubber layer is supported on the rubber protrusion and the upper end surface of the hydraulic shock absorber, and the upper end of each hydraulic shock absorber is fixed on the lower surface of the upper composite material rubber layer.

[0011] Preferably, the upper composite rubber layer is made of elastic polyurethane reinforced rubber composite material and is connected to the rubber protrusion and the hydraulic shock absorber by adhesion.

[0012] Preferably, a threaded hole is provided on the rubber pad body at a position corresponding to each hydraulic shock absorber, and the hydraulic shock absorber is fixed to the rubber pad body by bolts, and the bolts are stainless steel bolts.

[0013] Preferably, the rubber pad body is composed of a UV stabilizer layer, a vibration and noise reduction layer, an LCE material layer, a carbon fiber heating layer, a barrier layer and a moisture-proof layer which are arranged in sequence from top to bottom. The vibration and noise reduction layer is made of sound-absorbing cotton material, the carbon fiber heating layer is a grid-like fiber, a moisture-proof pad is arranged at the lower end of the moisture-proof layer, and a plurality of moisture-proof grooves are evenly arranged at the bottom of the moisture-proof pad.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1) The utility model adopts elastic polyurethane reinforced rubber composite material through the upper rubber pad, and utilizes the high wear resistance and vibration absorption capacity of rubber material and the good elastic recovery capacity of elastic polyurethane, thereby improving the vibration reduction effect of the vibration reduction pad and the smoothness of train running; at the same time, by fixedly connecting the hydraulic shock absorber to the rubber pad body, they work together and complement each other, thereby enhancing the shock reduction effect. The hydraulic shock absorber can absorb higher frequency vibrations, while the rubber pad has a better absorption effect on lower frequency vibrations. The combination of the two can cover a wider range of vibration frequencies and achieve a better vibration reduction effect, thereby reducing passengers' discomfort and fatigue, further improving the ride comfort of the train, reducing noise and vibration, and providing a smoother driving experience, which is very beneficial for improving passenger satisfaction, reducing fatigue and improving operating efficiency.

[0016] 2) By fixing a layer of UV stabilizer on the upper side of the vibration-damping and noise-reducing layer, the vibration-damping pad's resistance to natural aging and material cracking is improved; at the same time, by providing a carbon fiber heating layer to provide heat, the vibration-damping and noise-reducing rubber pad body has an antifreeze effect, and can better maintain the original performance of the vibration-damping pad in extreme climate environments; furthermore, by evenly arranging a number of moisture-proof grooves at the bottom of the moisture-proof structure, the penetration of moisture on the bottom surface can be effectively reduced, and the corrosion rate of the rubber pad body can be reduced; in summary, the above three technical means have effectively improved the service life of the vibration-damping and noise-reducing composite rubber pad.

[0023] A rubber pad with an additional hydraulic shock absorber comprises a rubber pad body 1, a plurality of rubber protrusions 2, a plurality of hydraulic shock absorbers 3, and an upper composite material rubber layer 4, wherein the plurality of rubber protrusions 2 are vertically arranged and have the same length, the rubber protrusions 2 are arranged in multiple rows, the rubber protrusions 2 in each row are arranged at equal intervals, and the rows of rubber protrusions 2 are arranged at equal intervals, the hydraulic shock absorbers 3 are arranged in multiple rows, the rows of hydraulic shock absorbers 3 are arranged at equal intervals, and the hydraulic shock absorbers 3 in each row are arranged at equal intervals, and the upper composite material rubber layer 4 is supported on the upper end surface of the rubber protrusions 2, the lower end of each hydraulic shock absorber 3 is fixed to the rubber pad body 1, and the upper end is fixed to the lower surface of the upper composite material rubber layer 4.

[0024] The rubber protrusion 2 is a columnar structure, which is arranged vertically. Each rubber protrusion 2 is provided with a central hole 201. By opening a through hole in the rubber protrusion hole column, the softness and compressibility of the rubber pad can be increased.

[0025] The upper composite material rubber layer 4 is made of elastic polyurethane reinforced rubber composite material and is connected to the rubber protrusion 2 and the hydraulic shock absorber 3 by adhesion.

[0026] A threaded hole 102 is provided on the rubber pad body 1 at a position corresponding to each hydraulic shock absorber 3, and the hydraulic shock absorber 3 is fixed to the rubber pad body 1 by a bolt 301. The bolt 301 is a stainless steel bolt, and a gasket 302 is sleeved on the bolt 301, and the gasket 302 is made of stainless steel.

[0027] The rubber pad body 1 is composed of a UV stabilizer layer 11, a vibration and noise reduction layer 12, an LCE material layer 13, a carbon fiber heating layer 14, a barrier layer 15 and a moisture-proof layer 16, which are arranged in sequence from top to bottom. The UV stabilizer layer 11 is made of UV stabilizer, and the vibration and noise reduction layer 12 is made of sound-absorbing cotton material for noise reduction. The LCE material layer 13 has high mechanical strength and durability, which can enhance the service life and stability of the rubber pad. Combining the LCE material with the rubber pad can provide better durability and stability while maintaining the softness and elasticity of the rubber pad, thereby extending the service life of the vibration reduction system. The carbon fiber heating layer 14 is a grid-shaped fiber, which realizes the uniformity of heating the vibration reduction pad and ensures that the vibration and noise reduction rubber pad body 1 can maintain its normal function in winter. The barrier layer 15 is made of rubber material, which can limit the vibration to the maximum limit above the moisture-proof layer to avoid damage and wear of the moisture-proof layer due to vibration.
