Assembly type limiting structure for ballastless track and ballastless track with structure

Abstract

The invention discloses an assembly type limiting structure for a ballastless track. The assembly type limiting structure comprises a limiting body, a first limiting hole, a second limiting hole and a limiting tooth, wherein a groove is formed in one end face of the two opposite end faces of the limiting body; the first limiting hole is used for nesting one end of the limiting body; the second limiting hole is used for making the other end of the limiting body inserted into the second limiting hole; the limiting tooth can be matched with the groove when one end of the limiting body is inserted into the limiting tooth, a bolt hole is formed in the limiting tooth, and the limiting tooth can be communicated with a through hole in the limiting body when the limiting body is inserted into the second limiting hole so that the bolt can penetrate through the through hole for connection and fix the limiting body to a base, and limiting of a track board is achieved through matching of the limiting body and the first limiting hole. The invention further discloses the ballastless track with the limiting structure. Detachable limiting of the track board can be achieved through the optimized structure improvement, limit stress deformation meets the requirements, and subsequent disassembly, assembly and maintenance of the track board are greatly facilitated.

Description

technical field [0001] The invention belongs to the technical field of ballastless tracks, and in particular relates to an assembled limiting structure for ballastless tracks and a ballastless track with the limiting structure. Background technique [0002] Ballastless track refers to the track structure that uses concrete, asphalt mixture and other integral foundations to replace the loose-grained gravel track bed. Compared with the ballasted track, the ballastless track avoids ballast splashing, has good smoothness, good stability, long service life, good durability, and less maintenance work, and is being used more and more. [0003] The structure of slab ballastless track mainly involves structures such as track slab, asphalt mortar or self-compacting concrete filling layer, base or supporting layer, wherein the base or supporting layer adopts concrete structure, and the asphalt mortar or self-compacting concrete filling layer laid on the base or supporting layer The la...

AI Technical Summary

Problems solved by technology

[0004] The limit method of the above-mentioned slab ballastless track type is poor in disassembly and assembly. Once the track plate is damaged, it is very inconvenient to maintain; in addition, the above limit Bit structure also has deficiencies in force and deformation requirements

Therefore, it is necessary to design an assembly-type ballastless track limit structure to solve the problem of inconvenient maintenance of the track plate limit existing in the current limit structure of the slab ballastless track, and to improve the force and deformation requirements of the current limit structure
