Embodiment 1

[0079] As shown in Figure 1 and Figure 2, 1 in the figure is a concrete sleeper, and 2 is an elastic covering material. The elastic covering material 2 covers the outer surface of the concrete upper sleeper 1 close to 2 / 3 of the lower part of the sleeper and covers the end surface and the bottom surface. The elastic covering material is made of rubber or rubber-plastic or polyurethane elastomer, which is directly molded on the surface of the sleeper by high-temperature injection, and is fastened to the sleeper by utilizing the material’s cooling shrinkage at low temperature and the slope structure of the concrete sleeper. Anchor and glue for fixing. The sleeper can adopt the concrete sleeper of TB / T2190-2002 standard. This kind of cladding form does not need to change the structural size and section of the sleeper, and has vertical, longitudinal, and horizontal three-dimensional vibration reduction performance, amplitude reduction, and noise reduction performance.

Embodiment 2

[0081] As shown in Figure 3 and Figure 4, 1 in the figure is a concrete sleeper, and 2 is an elastic covering material. The elastic covering material 2 covers the outer surface of the concrete upper sleeper 1 close to 2 / 3 of the lower part of the sleeper and covers the end surface and the bottom surface. The bottom surface of its coating adopts the form of interval grooves, and the interval grooves are rectangular, so that the elastic covering material 2 can be saved compared with embodiment 1, and the ballast is embedded in it, which also increases the distance between the ballast, the sleeper and the bottom surface covering material. frictional resistance. Others are the same as embodiment 1.

Embodiment 3

[0083] As shown in Figure 5 and Figure 6, 1 in the figure is a concrete sleeper, and 2 is an elastic covering material. The elastic covering material 2 adopts the form of covering the outer surface of the concrete sleeper 1 close to 2 / 3 of the lower part of the sleeper and covering the end surface and the bottom surface. The two sides of its cladding adopt interval form, and interval is rectangle, can save elastic cladding material 2 like this with respect to embodiment 1, simultaneously ballast is embedded in it, has also increased the friction between ballast and sleeper and side cladding material. resistance. Others are the same as embodiment 1.

Abstract

The present invention relates to sleeper, and is especially one kind of clad elastic sleeper. The clad elastic sleeper includes concrete sleeper and elastic cladding material in the bottom and side faces and/or end faces. Cladding the concrete sleeper with elastic cladding material can raise the elasticity of track, lower the global rigidity one the track, reduce the mutual action between wheel and track, raise the comfort and safety of train and reduce the impact of train to the track.

Description

technical field [0001] The invention relates to a sleeper supporting railway rails, in particular to a covered elastic sleeper. Background technique [0002] Generally speaking, there are three kinds of sleepers used in the track, wooden sleepers, concrete sleepers and other sleepers represented by metal materials. [0003] Due to the erosion of natural environments such as wind, rain, and sun, wooden sleepers will age and decay, and their service life is short. The station line can still be seen. In addition, the line stability of wooden sleepers is not good, so it is not suitable for high-speed and heavy-haul railways. [0004] Concrete sleepers are currently the most widely used sleepers in my country. However, concrete sleepers have high rigidity and insufficient elasticity. During the operation of the train, the ballast will be crushed and pulverized, resulting in defects such as slurrying, whitening, and hardening of the track bed. Part of the ballast will be replace...
