Multi-angle steering control platform for corrugated steel web prestressed box girder bridge

Abstract

The invention discloses a multi-angle steering control platform for a corrugated steel web prestressed box girder bridge. The multi-angle steering control platform comprises a concrete box girder, twosets of grabbing plates are symmetrically installed at the two ends of the concrete box girder, a plurality of sets of steel cables are evenly connected to the upper portions of the two sets of grabbing plates, and a bridge erecting machine body is arranged above the steel cables. The lower surface of the bridge girder erection machine body is fixedly connected with a plurality of sets of steel cables, two sets of driving supporting plates are symmetrically installed on one side of the bridge girder erection machine body, two sets of limiting supporting plates are symmetrically installed on the other side of the bridge girder erection machine body, guide grooves are longitudinally formed in the middles of the driving supporting plates, hydraulic pushers are movably installed in the guidegrooves, and winches are arranged above the guide grooves. The operation platform specially used for adjusting the angle of the box girder is designed at the joint of the bridge girder erection machine and the concrete box girder, and through the driving mechanism installed on one side of the bridge girder erection machine and the limiting mechanism installed on the other side of the bridge girdererection machine, accurate angle adjustment can be conducted on the concrete box girder; and the concrete box girders are accurately spliced and mounted.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a multi-angle steering control platform for corrugated steel web prestressed box girder bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the abutment; the auxiliary structures refer to...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-angle steering control platform for corrugated steel web prestressed box girder bridge, which solves the problem of connecting with the concrete box girder below by using steel cables and carrying out overhead displacement generally through the bridge erecting machine. When moving to the position to be installed, the lower processing will be carried out. However, during the moving process, the steel cable will drive the concrete box girder below to have an angular offset, which will easily lead to incomplete butt joints between the concrete box girders, and it is inconvenient to adjust the angle. this technical issue
