Embodiment

[0023] An adjustable gauge modular steel structure track bed, its structure is as follows Figure 1-3 As shown, it is a modular structure spliced ​​sequentially, and each module is made into different lengths between 2m and 5m. Adjacent modules are connected through connecting plates 10 and fixing bolts 11 for connecting plates. The module includes longitudinal channel steel frames 1 and transverse channel steel frames 2 that are vertically connected to each other. The longitudinal channel steel frames 1 are arranged on both sides of the track 4 and the distance is adjusted according to the gauge of the track 4. On the basis of installation, the gauge of the track 4 is 143.5-1435mm, that is, the gauge varies from the standard gauge of 1435mm to the gauge of 1:10, and the gauge of the corresponding longitudinal channel steel frame 1 is 500-2500mm. A reinforcement partition 5 is provided at the bottom of the longitudinal channel steel frame 1 . The connecting plate 10 is a rubb...

Abstract

The invention relates to a modularized steel structure track bed with an adjustable gauge. The modularized steel structure track bed is formed by sequentially splicing by adopting a modularized structure, and adjacent modules are connected through a connecting plate by bolts; the modules comprise longitudinal groove steel frames and lateral groove steel frames, which are mutually connected vertically, wherein the longitudinal groove steel frames are arranged on both sides of each of tracks, a distance is regulated according to the gauge of the tracks, and the longitudinal groove steel frames are mounted on a track bed mounting base through basic connecting seats; the tracks are fixedly connected to the lateral groove steel frames. Compared with the prior art, the modularized steel structure track bed disclosed by the invention can determine the gauge according to specific application, then selects the tracks with the corresponding gauges and the track bed modules, the modules are sequentially connected together in the longitudinal direction through the connecting plate to form the required track length, and the basic connecting seats are connected with the track bed mounting bases or other devices through bolts in the vertical direction and the lateral direction so as to have the function of regulation; the modularized steel structure track bed is convenient to assemble and mount.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to an adjustable gauge modular steel structure track bed. Background technique [0002] Arterial rail transit such as high-speed rail, general freight and passenger rail, and urban rail transit are the main forms of transportation that are often seen by most people and go to work. There are many applications: mines, parks, factories, rail transit test lines, construction sites, etc. So far, the rails used in rail transit are basically installed on ballastless monolithic ballast beds made of reinforced concrete, ballasted and sleeper ballast beds, or directly installed in concrete foundations. It is basically impossible to move and disassemble them; Some of the transportation applications are used for a long time, and some are used in different places for a short period of time, and are often relocated and assembled. Based on the above-mentioned different ...
