Ballastless track assembly for longitudinal and transverse beam system steel bridge, construction device and technology

Abstract

The invention relates to a ballastless track assembly for a longitudinal and transverse beam system steel bridge, a construction device and a process. The ballastless track assembly is used for a track plate arranged on a steel beam. A rail bearing table is arranged on the rail plate, and a steel rail is laid on the rail bearing table through fasteners; pull-bearing rods are arranged on the longitudinal end faces of the track plates, and connecting assemblies are arranged between the pull-bearing rods of the longitudinally adjacent track plates; the threaded section of the pulled rod enters the connecting assembly and is fastened through a connecting nut; a sliding groove is longitudinally formed in the track plate, and a mounting hole is vertically formed in the sliding groove. and the track plate and the flange of the steel beam are fastened and connected through bolts in the mounting holes. The assembly is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a ballastless track assembly, a construction device and a process for a steel bridge of a longitudinal beam system. Background technique [0002] The ballastless track structure on the existing longitudinal beam system steel bridge and the bridge longitudinal beam system are mainly connected by high-strength bolts and other methods to achieve approximately rigid connection. [0003] The rigid connection between the steel bridge and the ballastless track structure increases the influence of bridge deformation on the ballastless track; [0004] (1) In terms of the force of the ballastless track seamless line on the steel bridge, due to the rigid connection, the interaction between the bridge and the ballastless track structure is increased, and when the bridge stretches and deforms, it will cause a huge expansion and expansion force to accumulate in the steel rail , if the temperature span of the steel bridge is slightly larger,...

AI Technical Summary

Problems solved by technology

[0005] (2) The connection position of ballastless track structure steel bridge generally adopts steel and other structures, while the ballastless track is mainly a concrete structure. During the operation of the line, there will inevitably be contact between steel and concrete, which will cause various diseases at the connection parts and increase maintenance workload, etc., reducing the service reliability of the entire system and threatening the safe operation of trains

[0006] To this end, it is an urgent technical problem to provide a set of ballastless track components, construction equipment and technology for steel bridges with longitudinal and horizontal beam systems, to provide the safety of train operation, and to solve the problems of one-way bridge operation and inconvenient U-turn. The force of the anti-loosening structure is not applicable
