In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-2, the specific structure of the present invention is: the utility model provides a ballast sleeper is turned over to self-adaptation, includes the sleeper 1 of cuboid shape, and pre-buried on the sleeper 1 has the bolt that is used for installing rail 7, 1 bottom of sleeper is equipped with turns over the ballast structure, turn over the ballast structure and include first toper structure 2 and second toper structure 3, 2 big ends up in the cross-section of first toper structure, its upper end is connected with 1 bottom of sleeper, and the lower extreme is connected with 3 upper ends of second toper structure, 3 big ends up in the cross-section of second toper structure.

Preferably, the first conical structural body 2 is in a regular truncated cone or regular polygonal pyramid structure shape, and the second conical structural body 3 is in an inverted truncated cone or inverted polygonal pyramid structure shape. Is convenient for production and manufacture.

Preferably, the first conical structural body 2 has a regular quadrangular pyramid structure, and the second conical structural body 3 has an inverted quadrangular pyramid structure. Preferably, the first conical structural body 2 is in a right circular truncated cone structure, and the cone angle is 30-90 degrees; the second conical structure 3 is in an inverted conical frustum structure, and the cone angle of the second conical structure is 30-90 degrees.

Preferably, an elastic base plate 4 is arranged at the bottom of the ballast turning structure. The amount of displacement of the sleeper 1 to sink and rise is increased, typically up to 10 mm.

Preferably, the external surface of the ballast overturning structure is rough. Increasing the friction with the ballast 9.

Preferably, the outer surface of the second conical structural body 3 is uniformly provided with a plurality of grooves 5 with obliquely downward openings. The friction force between the block-shaped railway ballast 9 and the railway ballast is increased, and particularly, the effect of the extrusion force on the block-shaped railway ballast 9 is better.

Preferably, the ballast overturning structures are uniformly distributed at the bottom of the sleeper 1 along the length extension direction of the sleeper and are respectively positioned at the bottom of the sleeper 1 right below the position where the steel rail is installed.

Preferably, the upper end of the first conical structural body 2 is connected with the bottom of the sleeper 1 through a transition body 6. The transition body 6 is in a conical or prismatic shape, the lower end face of the transition body is superposed with the upper end face of the first conical structural body 2, the angular stress effect of the joint of the sleeper 1 and the first conical structural body 2 is reduced, and fracture is prevented.

When the sleeper 1 is used specifically, after the sleeper 1 is installed on a track bed, the railway ballast 9 is filled around the sleeper 1, the first conical structural body 2 and the second conical structural body 3, the blocking bodies which are diffused all around need to be blocked around the railway ballast, preferably, the railway ballast 9 is filled in a pit, when a train passes through the pit, the sleeper 1 is lifted and moved under the combined action of the train pressure (gravity) and the resilience force of a foundation, the maximum displacement is usually not more than 10mm, when the sleeper 1 descends, the second conical structural body 3 extrudes the railway ballast 9 to the lower side of the second conical structural body through the extrusion force of the side surface (both vertical thrust and transverse thrust), and the railway ballast 9 on the periphery of the first conical structural body 2 descends for certain displacement; when the sleeper 1 rises, the second conical structure 3 falls through the side face, the railway ballast 9 moves towards the lower space of the second conical structure 3 under the action of the self weight (in addition, the impact vibration effect on the track 7 when the train passes by) to be supplemented, and the railway ballast 9 on the periphery of the first conical structure 2 slides downwards along the inclined plane to be supplemented, so that the railway ballast 9 is circularly turned in a certain range (as shown in figure 1), the turning frequency of the railway ballast turning vehicle on the railway ballast is greatly reduced, and the equipment and manpower maintenance cost is reduced; in addition, the anchoring effect of the sleeper is greatly improved compared with that of a common flat sleeper; the sleeper only reduces the frequency of turning the railway ballast, has the best effect on the periphery of a ballast turning structure, gradually weakens the effect after being far away, and still needs to manually turn the railway ballast through a ballast turning vehicle after being used for a long time.
