Technical Field
[0001] This utility model relates to the field of rubber shock-absorbing pad technology, and in particular to a high-service-life railway rubber shock-absorbing pad. Background Technology
[0002] The rubber damping pads used for railway track vibration reduction are rubber elastic pads, also known simply as elastic pads. These rubber elastic pads are an important component of the track structure, installed between steel and concrete sleepers. Their main function is to buffer the vibration and impact of high-speed vehicles, protect the roadbed and sleepers, provide electrical insulation, and support the signaling system. Because these extra rubber pads are exposed to the atmosphere for extended periods, they require excellent resistance to natural aging, cold, and heat. Subway rubber pads offer good vibration damping performance, resulting in low noise.
[0003] Currently available rubber elastic pads on the market are mostly straight plates or have a buffer groove on one side. They suffer significant wear and tear during load-bearing applications. Often, during rail maintenance, they need to be aligned and replaced. Existing methods for replacing shock-absorbing pads are cumbersome, requiring the replacement of the entire shock-absorbing pad on the corresponding rail. This replacement method is time-consuming and complex. Therefore, this utility model provides a high-service-life rubber shock-absorbing pad for rails to solve the problems mentioned in the background. Utility Model Content
[0004] The purpose of this invention is to provide a long-life railway track rubber shock-absorbing pad to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-service-life railway track rubber vibration damping pad, comprising a railway track rubber vibration damping pad, wherein the railway track rubber vibration damping pad is spliced from individual rubber vibration damping pad units, wherein the left side of each individual rubber vibration damping pad unit is provided with a splicing protrusion, and the right side of each individual rubber vibration damping pad unit is provided with a splicing recess, wherein each individual rubber vibration damping pad unit is connected to the right side of another individual rubber vibration damping pad unit through the splicing protrusion on the left side, wherein each individual rubber vibration damping pad unit is divided into a rubber vibration damping pad top plate and a rubber vibration damping pad bottom plate, wherein the rubber vibration damping pad top plate and the rubber vibration damping pad bottom plate are connected by a snap-fit method, wherein the top of the rubber vibration damping pad top plate is provided with rubber protrusions, and the bottom of the rubber vibration damping pad top plate is provided with a connecting clip, and the bottom of the rubber vibration damping pad bottom plate is fixedly installed with a buffer column.
[0006] As a preferred embodiment of this utility model, the rubber protrusion has a metal sheet inside, and the outside of the metal sheet is wrapped with rubber.
[0007] As a preferred technical solution of this utility model, the top of the rubber shock-absorbing pad base plate is provided with a connecting groove, the connecting groove is distributed on both sides of the buffer column, the bottom of the rubber shock-absorbing pad top plate is provided with a connecting protrusion, the connecting protrusion is distributed on both sides of the connecting block, the connecting protrusion is laterally engaged with the connecting groove, and the rubber shock-absorbing pad top plate and the rubber shock-absorbing pad bottom plate are laterally engaged with the connecting protrusion and the connecting groove.
[0008] As a preferred technical solution of this utility model, the interior of the rubber shock-absorbing pad unit is composed of five sets of metal plates, the outer sides of the five sets of metal plates are wrapped with a rubber layer, and a rubber layer is also provided between adjacent metal plates.
[0009] As a preferred technical solution of this utility model, the top of the rubber shock-absorbing pad base plate is provided with an opening that matches the connecting block, and the buffer column is placed in the opening. The buffer column adopts a split column structure inside, and a strong buffer spring is provided between the columns.
[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses individual rubber shock-absorbing pads, allowing the railway track rubber shock-absorbing pads to be spliced together. When there is wear and tear requiring maintenance, only the corresponding individual pads need to be replaced. Moreover, the individual shock-absorbing pads adopt an upper and lower split structure design. When only the top plate is damaged, only the top plate structure needs to be replaced, without replacing the entire structure. This reduces material consumption and enables faster maintenance and replacement.
[0011] This invention features a rubber protrusion on the top of the rubber shock-absorbing pad. This protrusion combines metal sheets and rubber, improving the overall impact resistance of the pad. Located at the very top, the protrusion provides both cushioning and rigidity, ensuring the pad's longevity. The internal design incorporates buffer columns for enhanced cushioning. Furthermore, the combination of five layers of metal plates and rubber layers further enhances the pad's impact resistance without compromising its cushioning effect, significantly extending its lifespan.
