AI Technical Summary

Technical Problem

In the construction process of installing an externally covered acoustic barrier on high-speed rail bridges, due to the high-speed rail bridge's own height, it is difficult to set up the construction platform, which leads to obstacles in construction and poses major safety hazards.

Method used

A high-speed rail outer cover acoustic barrier mobile construction system is designed, including main truss, longitudinal trusses, mounting frames, anti-capsulation wheels, walking mechanisms and tracks. By erecting tracks on the top of the sound barrier, using a construction platform with a suspended door shaped structure, combined with the design of the walking mechanism and anti-capsulse wheel, it is possible to conveniently lay out the outer panels on the high-speed rail bridge.

Benefits of technology

This system can easily complete the construction of the outer cover acoustic barrier on the high-speed rail bridge, which is simple and convenient to operate, avoiding construction obstacles and safety hazards.

Abstract

The utility model relates to the technical field of high-speed rail outer covering type sound barrier construction, in particular to a high-speed rail outer covering type sound barrier moving construction system which comprises two main trusses, longitudinal trusses, a mounting frame, first overturn-preventing wheels, a walking mechanism and a track. The longitudinal truss is arranged between the two main trusses, and two ends of the longitudinal truss are respectively connected with the two main trusses; the two main trusses are each provided with a portal steel frame structure, and walking mechanisms are arranged at the bottoms of horizontal beams of the main trusses. The track is fixed to the top of the sound barrier framework, and the walking mechanism can move along the track. The mounting frame is arranged on the inner side of the bottom of a vertical beam of the main truss, the first anti-overturning wheel is arranged on the mounting frame, and the wheel face of the first anti-overturning wheel abuts against the bottom face of a box beam flange plate of a bridge. By means of the high-speed rail outer covering type sound barrier moving construction system, construction of an outer bed board of an outer covering type sound barrier on a high-speed rail bridge can be easily completed, and operation is easy and convenient.
