Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit equipment technology, specifically a rubber connector structure for vibration reduction of rail vehicles. Background Technology
[0002] Track rubber pads are commonly used vibration damping components in rail transit, typically placed between the track sleepers and the concrete subbase. They reduce vibration and noise generated by running trains, improving the comfort and quietness of railway lines. They also reduce wear between the rails and the track base, extending the service life of both rails and tracks, and reducing maintenance costs. However, existing track rubber pads are usually one-piece designs. After long-term use, localized wear and cracking may occur, but in such cases, only the entire track rubber pad can be repaired; undamaged sections cannot be reused, potentially leading to resource waste and limited practicality.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] Please see Figure 1-6In this embodiment of the utility model, a rubber connector structure for vibration damping of rail vehicles includes: a protective sleeve 100, a limiting mechanism 200, and a height adjustment mechanism 300. A rubber frame 110 is bonded and fixed inside the protective sleeve 100, and multiple elastic blocks 130 are integrally formed at both ends of the top of the protective sleeve 100. Multiple vibration damping components are provided inside the rubber frame 110. The limiting mechanism 200 is located at the bottom of the rubber frame 110, and the height adjustment mechanism 300 is located at the bottom of the limiting mechanism 200.
[0033] Specifically, the limiting mechanism 200 is used to limit and fix the positions of multiple vibration damping components, and the height adjustment mechanism 300 is used to facilitate the adjustment of the overall thickness, thereby improving the applicability of the rubber connector structure for vibration damping of rail vehicles. The protective sleeve 100 is used to shield and protect the rubber frame 110, preventing wear on the rubber frame 110. The protective sleeve 100, multiple rubber frames 110, multiple elastic blocks 130 and multiple vibration damping components work together to improve the vibration damping effect of the rubber connector structure for vibration damping of rail vehicles during use. When the rubber connector structure for vibration damping of rail vehicles is partially damaged, the limiting mechanism 200 is used to facilitate the removal of multiple vibration damping components, thereby facilitating the removal of the damaged parts without having to replace the entire rubber connector structure for vibration damping of rail vehicles, thus avoiding waste of resources.
[0034] like Figure 2-5As shown, in this embodiment, the vibration damping component includes: a protective pad 120, a rubber pad 150, and a connecting plate 160. The protective pad 120 is disposed inside the protective sleeve 100. The top of the rubber pad 150 is bonded and fixed to the bottom of the protective pad 120. The rubber pad 150 is slidably inserted into the inside of the rubber frame 110. The top of the connecting plate 160 is bonded and fixed to the bottom of the rubber pad 150. The top of the protective pad 120 is uniformly and integrally formed with multiple elastic strips 140. The materials of the protective sleeve 100, the protective pad 120, the multiple elastic blocks 130, and the multiple elastic strips 140 are all polyurethane rubber. The limiting mechanism 200 includes: a fixing plate 210 and a rubber pad 220. The top of the fixing plate 210 is bonded and fixed to the bottom of the protective sleeve 100 and the rubber frame 110. Multiple insertion holes 211 are provided at both ends of the fixing plate 210, and the interior of the multiple insertion holes 211... Each of the multiple plug-in blocks 212 is slidably inserted. The top of each plug-in block 212 is fixedly connected to the bottom of the corresponding connecting plate 160. Each of the multiple plug-in blocks 212 has a limiting hole 213 at its bottom. The top of the second rubber pad 220 is bonded and fixed to the bottom of the fixing plate 210. Each of the two ends of the second rubber pad 220 has a multiple limiting notch 221 at its top and a multiple plug-in groove 222 at its bottom. Each end of the second rubber pad 220 is provided with a plug-in assembly. The materials of the second rubber pad 220, the rubber frame 110 and the multiple first rubber pads 150 are all butadiene rubber. The plug-in assembly includes a movable plate 230. Each side of the movable plate 230 has a multiple connecting notch 231. Each inner sidewall of the multiple connecting notches 231 is bonded and fixed with a limiting plate 232. One end of the limiting plate 232 passes through the limiting hole 213 and is slidably inserted into the corresponding limiting notch 221.
[0035] In this embodiment, the protective sleeve 100, protective pad 120, multiple elastic blocks 130, and multiple elastic strips 140, all made of polyurethane rubber, exhibit strong wear resistance and excellent tear and impact resistance, performing well under dynamic loads. This effectively protects the rubber frame 110 and rubber pad 150, thereby improving the service life of the rubber connector structure for vibration damping of the rail vehicle. Furthermore, the butadiene rubber pad 220, rubber frame 110, and multiple rubber pads 150 ensure good elasticity of the rubber connector structure for vibration damping of the rail vehicle, thus improving its vibration damping effect during use. When the rubber connector structure for vibration damping of the rail vehicle is damaged, the two moving plates 230 are pulled out, allowing the limiting plate 232 to separate from the corresponding limiting hole 213 and limiting notch 221. This facilitates the removal of the vibration damping component and the limiting hole 213, making it easier to replace the damaged parts.
[0036] Example 2
[0037] Based on Embodiment 1, in order to adjust the overall thickness of the rubber connector structure for vibration damping of rail vehicles, so that the rubber connector structure for vibration damping of rail vehicles can be adapted to different usage requirements.
[0038] like Figure 6 As shown, in this embodiment, the height adjustment mechanism 300 includes a plurality of rubber pads 310, the bottom of the rubber pads 310 is provided with a plurality of insertion slots 311, the top of the rubber pads 310 is integrally formed with a plurality of insertion strips 320, the length of the rubber pads 310 is the same as the length of the protective sleeve 100, and the width of the rubber pads 310 is the same as the width of the protective sleeve 100.
[0039] In specific implementation, multiple insertion slots 311 and multiple insertion strips 320 are used to splice multiple rubber pads 310. By inserting multiple insertion strips 320 on the top rubber pad 310 into multiple insertion slots 222, the installation of the height adjustment mechanism 300 is completed. By adjusting the number of spliced rubber pads 310, the overall thickness of the rubber connector structure for vibration damping of rail vehicles can be adjusted, so that the rubber connector structure for vibration damping of rail vehicles can be adapted to different usage requirements. When splicing and installing multiple rubber pads 310, glue can be applied to the surface of the insertion strips 320 to ensure the firmness of the height adjustment mechanism 300 after splicing and installation.
