Problems solved by technology

[0005] In the prior art, the sleepers used in heavy-haul railways are designed according to the maximum axle load of trucks of 25 tons. The strength of the sleepers is not enough to fully meet the needs of heavy-duty tracks, and the lateral resistance between the sleepers and the ballast bed is insufficient, which is prone to line failure. Lateral displacement, which affects the transportation efficiency of heavy-haul railways and increases the operational risk of heavy-haul railways

Embodiment Construction

[0023] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0024] The invention provides a safe and stable railway sleeper, such as figure 1 As shown in 3 to 3 , the railway sleeper includes a main body 10 and a resistance block 20 , and the resistance block 20 is arranged on the side of the main body 10 .

[0025] The safe and stable railway sleeper provided by the present invention includes a resistance block 20. When the railway sleeper is laid in the ballast bed, the resistance block 20 can increase the lateral resistance between the railway sleeper and the ballast bed, thereby avoiding the lateral displacement of the track line caused by the lateral displacement of the railway sleeper , to ensure the safe and smooth operation of the train. For ex...

Abstract

The invention provides a safe and steady railway sleeper. The safe and steady railway sleeper comprises a body and resistance blocks, and the resistance blocks are arranged on the side face of the body. The railway sleeper comprises the resistance blocks, when the railway sleeper is laid in a ballast bed, the resistance blocks can increase the transverse resistance formed between the railway sleeper and the ballast bed, then track line transversal displacement caused by transversal displacement of the railway sleeper is avoided, and safe and steady running of a train is guaranteed.

Description

technical field [0001] The invention relates to the field of railway construction, in particular to a safe and stable railway sleeper. Background technique [0002] At present, heavy-haul railway transportation is widely valued by countries all over the world because of its large transportation capacity, high efficiency and low transportation cost. Some countries with vast territory, abundant resources, and bulk cargoes such as coal and ore account for a relatively large proportion of transport volume, such as the United States, Canada, Brazil, Australia, South Africa, etc., are focusing on the development of heavy-haul railways and operating a large number of heavy-haul trains. Moreover, heavy-duty trains have also begun to operate on the passenger-cargo mixed main lines in Europe. [0003] my country's existing ballast track lines are also vigorously developing heavy-duty cargo transportation. Because heavy-duty trains have the characteristics of high speed and large capa...
