Device for detecting and maintaining mobile bridge structure

Abstract

A movable bridge structure detection and maintenance device of the invention belongs to the bridge detection, maintenance and construction equipment, which comprises two counterbalance cars (6) each of which is hinged with at least three cantilever racks (7) in one side relative to the bridge surface and an examining and repair bench (5) with a length relative to the width of the bridge surface, wherein both sides of the width direction of the examining and repair bench (5) end are respectively provided with two suspension points (10), a suspension rope (8) is arranged on the suspension arm of the suspension rack (7) and is connected to the suspension point (10) on one end of the examining and repair bench (5). The examining and repair bench (5) is a rectangle truss and provides spacious working surface of the bridge detection and construction with rapid and easy detection and construction, short assistant time, high work efficiency and good safety, solves the avoidance problem when the bridge counterbalance cars encounter bridge side lamp rods (3) or cables, and can be used for bridges with surface of any widths, in particular for the cable-stayed bridge which cannot use prior special bridge detection cars.

Description

technical field [0001] The invention relates to equipment for bridge detection and maintenance construction, in particular to a mobile bridge structure detection and maintenance device that provides a working platform for bridge bottom surface detection and maintenance. Background technique [0002] At present, a large number of bridge structures built in my country have entered a period of mass maintenance and maintenance. In order to have a comprehensive and objective understanding and evaluation of the current status of bridge use, structural testing is generally carried out first. If problems are found, the problematic parts need to be repaired. Carry out maintenance work. Because the bottom surface of the bridge is the air-facing surface, it is difficult for the staff to be in place. In order to facilitate the structural inspection of the bottom surface of the bridge, there are special bridge inspection vehicles in China. The technical scheme of the new name "New Bridge...

AI Technical Summary

Problems solved by technology

But the aforementioned bridge inspection vehicle also has some inconveniences and deficiencies in use

First, due to the limitation of the vehicle load and body size, when the bridge deck is wide, the bending and extending arm cannot extend the working platform to the middle of the bridge bottom, resulting in the inability to detect and construct the middle part of the bridge bottom 4; the second is the working platform The area is narrow and can only bear small equipment weight and few staff

The extension arm of the engineering inspection vehicle is used as a maintenance construction platform, the working surface is difficult to expand, the construction efficiency is low, the construction period is affected, and the normal passage of vehicles on the bridge deck is also affected; the third is when there are street light poles 3 installed on both sides of the bridge deck, the engineering inspection vehicle In the process of driving along the bridge deck, in order to avoid the street light pole 3, the extension arm 2 of the working platform needs to be folded up and down frequently, and the staff also need to climb up and down accordingly, which consumes physical strength and is an auxiliary tool for bridge inspection and maintenance. The time is prolonged, and the construction efficiency is reduced; the fourth is that the extension arm 2 and the engineering vehicle 1 are rigidly connected and have a width requirement. position, the extension arm 2 of engineering vehicle 1 is blocked by the cable and cannot extend to the bottom of the bridge
