Distance adjustable X type anti-sliding sleeper

Abstract

The invention provides a distance adjustable X type anti-sliding sleeper. The distance adjustable X type anti-sliding sleeper comprises an X type sleeper main body which is formed by splicing two components in the up-and-down direction; the two components are long strip-shaped sleeper structures with circular discs at the middle parts and symmetric external extending sleeper sections on the two sides; four steel rail mounting grooves are symmetrically formed in the sleeper sections in the four extending directions of the X shape; the circular discs at the middle parts are divided into upper and lower layers; the upper and lower layers of circular discs are connected with each other through axial through holes; and through relative rotation between the upper and lower layers of circular discs, the distances between the steel rail mounting grooves, in the same steel rail direction, of the X type sleeper are adjusted. The distance adjustable X type anti-sliding sleeper is suitable for multiple environments by adjusting the sleeper distance, and therefore, the contact area between the sleeper and a railway ballast is effectively increased, the stress on the sleeper is dispersed to fourincluded angle ranges of the X shape, the anti-sliding capacity of the sleeper in the running direction and the lateral direction is greatly improved, loosening and breaking of the railway ballast generated by the sliding of the sleeper are reduced, safe and stable operation of a train is guaranteed, the stability of the railway ballast is improved, and the maintenance period of the railway ballast is prolonged.

Description

technical field [0001] The invention belongs to the field of railway engineering building components, in particular to an "X" type anti-sliding sleeper with adjustable sleeper spacing. Background technique [0002] As an important means of transportation, the role and function of railways are extremely critical in the transportation industry. Nowadays, with the development of railways in the direction of high speed, heavy load and environmental protection, and the requirements of railway transportation on tracks are becoming more and more stringent, such as high ride comfort, high stability, high durability, etc. As an important connecting part between the rail and the ballast, the sleeper plays an important role in ensuring the spatial position of the rail and dispersing the load transmitted from the rail to the ballast. Therefore, the working performance and durability of the sleeper become extremely critical. [0003] In recent years, many line surveys have found that th...
