Abstract

The invention discloses a self-adaptive ballast overturning sleeper. The self-adaptive ballast overturning sleeper comprises a cuboid sleeper body, a ballast overturning structure is arranged at the bottom of the sleeper body and comprises a first conical structure body and a second conical structure body, the section of the first conical structure body is small in top and large in bottom, the upper end of the first conical structure body is connected with the bottom of the sleeper body, the lower end of the first conical structure body is connected with the upper end of the second conical structure body, and the section of the second conical structure body is large in top and small. According to the self-adaptive ballast overturning sleeper, when a train passes by, the sleeper turns overrailway ballast under the combined action of train pressure and foundation resilience force, so that the railway ballast is circularly turned over within a certain range, the frequency of overturningover the railway ballast by a ballast turning vehicle is greatly reduced, and the maintenance cost of equipment and manpower is further reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transportation, in particular to an adaptive ballast turning sleeper. Background technique [0002] Track refers to the route paved with strip steel for trains, trams, etc. The traditional railway track usually consists of two parallel steel rails. The rails are fixed on sleepers, and gravel is laid underneath as ballast. With the increase of railway traffic volume, and the increase of locomotive vehicle axle load and driving speed, many new types of tracks have appeared one after another, such as seamless track, wide sleeper track, integral track bed track and slab track. In view of whether there is gravel as ballast under the track, it is divided into two types: ballasted track and ballastless track. [0003] Ballasted track refers to the track whose subrail foundation is stone loose-grained bed, also known as gravel track, which is one of the main forms of track structure. It has the advantages ...
