Bridge maintenance vehicle and method for avoiding bridge pier by maintenance platform

Abstract

The invention provides a bridge maintenance vehicle and a method for avoiding a bridge pier by a maintenance platform, and belongs to the field of bridge detection and maintenance construction. Cantilever hoisting devices (5) are arranged at a plurality of points on the two sides of a bridge floor, wherein a guide rope (3) connected with the maintenance platform (1) is pulled by an unmanned aerialvehicle (4) to transversely penetrate through the lower part of the bottom face of a bridge; hoisting ropes (2) are pulled to the cantilever hoisting devices (5); the operation of avoiding the bridgepier is achieved through the cooperative operation mode that a plurality of hoisting ropes (2) are pulled and rotated to be positioned on the maintenance platform (1) on the bottom face of the bridge; the movement of the maintenance platform (1) can be monitored by the unmanned aerial vehicle (4); the operation is visual and convenient, the multiple devices are cooperatively operated; the construction efficiency is high; the auxiliary time is short; the construction time for avoiding the bridge pier can be greatly shortened; the number of constructors is small; and the construction cost is reduced. The method is particularly suitable for conducting bridge pier avoiding construction operation on the bridge maintenance vehicle and the maintenance platform on the bridge with the large bridgefloor height, the large bridge bottom slope, the severe river channel condition, the poor bridge bottom construction environment and the poor condition.

Description

technical field [0001] The invention relates to a construction method for bridge detection and maintenance construction equipment, in particular to a bridge maintenance vehicle and a method for avoiding bridge piers by a maintenance platform. Background technique [0002] In recent decades, my country's transportation and bridge construction have made great progress and development. With a large number of roads and bridges put into use and operation, the maintenance of roads and bridges has become more and more important. my country also has a large number of roads The maintenance and maintenance of the bridge structure should be carried out in a timely manner for bridges and railway bridges. In order to have a comprehensive and objective understanding and evaluation of the current status of the bridge, the structural inspection is generally carried out first. If a problem is found, the problematic part needs to be repaired. . Because the bottom surface of the bridge is an ai...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned bridge inspection vehicles connected with the maintenance platform with flexible suspension ropes, which are greatly affected by the height of the bridge deck and the environment at the bottom of the bridge in the process of avoiding the bridge pier, resulting in inconvenient construction and installation, long period and high construction cost. , low work efficiency, and poor safety defects and deficiencies, to provide a construction and installation not affected by the height of the bridge deck building and the bridge bottom environment and the method of avoiding the bridge pier bridge maintenance platform, it avoids the bridge pier construction and installation is convenient, The cycle is short, the construction cost is low, the work efficiency is high, and the safety is high
