Embodiment 1

[0046] Embodiment 1 of the present invention provides an elastic backing plate at the bottom of a railway concrete sleeper, which is arranged between the bottom of the concrete sleeper and the ballast, and includes a raised structure 2, a rivet structure 3, an elastic layer 11 and a protective layer 12, and the raised structure 2 , rivet structure 3, elastic layer 11 and protective layer 12 integrally connected, elastic layer 11 adopts rubber, polyurethane or other similar materials to make, can be microporous foam structure also can be solid structure, its main function is to provide appropriate Elasticity, so as to effectively reduce the damage rate of the ballast bed, the material of the protective layer 12 includes rubber, polyurethane, blended cord fabric, polyester and non-woven fabric, so that the elastic layer 11 is protected from being damaged by the ballast under the operation load through the protective layer 12 , and the elastic layer 11 and the protective layer 12 ...

Embodiment 2

[0048] Embodiment 2 of the present invention provides an elastic backing plate for the bottom of a railway concrete sleeper, which is arranged between the bottom of the concrete sleeper and the ballast, and includes a raised structure 2, a rivet structure 3, an elastic layer 11, a protective layer 12 and a connecting layer 13, and The protruding structure 2, the rivet structure 3, the elastic layer 11, the protective layer 12 and the connection layer 13 are integrally connected. The elastic layer 11 is made of rubber, polyurethane or other similar materials, and can be a microporous foam structure or a solid structure. Its main function is to provide appropriate elasticity, thereby effectively reducing the damage rate of the ballast bed. The material of the protective layer 12 includes rubber, polyurethane, blended cord fabric, polyester and non-woven fabric, so that the elastic layer 11 can be protected by the protective layer 12 during operation. It will not be damaged by the...

Abstract

The invention provides an elastic base plate of a railway concrete sleeper bottom. The elastic base plate is arranged between the railway concrete sleeper bottom and a ballast and comprises an elasticbase plate base body, a bulge structure and a rivet structure; the elastic base plate base body, the bulge structure and the rivet structure are integrally connected; the bulge structure is arrangedat one side of the elastic base plate base body and is in contact with the ballast; the rivet structure is arranged at the other side of the elastic base plate base body and is connected with the railway concrete sleeper bottom. The elastic base plate of the railway concrete sleeper bottom, provided by the invention, is simple in structure and convenient and rapid to mount; enough ballast bed transverse resistance can be provided and the damage speed of a ballast bed is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an elastic backing plate at the bottom of a railway concrete sleeper. Background technique [0002] With the continuous development of industry, people's demand for fast and convenient travel is gradually increasing, and heavy-duty railways and high-speed railways are also experiencing a period of rapid development. Track is an important infrastructure in railway construction, and a good track structure is an important guarantee for safe, reliable, comfortable and efficient railway operation. At present, my country's railway track structure is divided into two types: ballastless track and ballasted track. Among them, ballastless track is mainly used in special sections of high-speed railways and other types of railways (such as in long tunnels), and from the perspective of laying length , the ballasted track is still the main track structure form of my country's railways. Th...
