Door connected bridge maintenance car

Abstract

The invention belongs to the technical field of repair and maintenance of bridges, and particularly relates to a door connected bridge maintenance car which comprises an upper lateral combination (1), wheeled walking cars (2), beams (3), vertical truss mechanisms (4), rotating devices (5), bottom detection platforms (6), jacking oil cylinders (7), walking mechanism longitudinal beams (8), vertical truss longitudinal beams (9), telescopic frames (12), surrounding frames (13), connecting oil cylinders (15), frame longitudinal beams (16) and chain wheel driving devices (17). According to the door connected bridge maintenance car, walking cars of two sides are connected with the upper lateral combination through flanges to form a portal frame structure, the bridge maintenance car can stably walk on a bridge floor by the aid of telescopic butting technique of the bottom detection platforms and collision avoidance technique of bridge side barriers, the maintenance car can rapidly avoid the barriers of bridge sides and bridge piers, lanes cannot be occupied, bridge traffic cannot be affected, the maintenance car is high in applicability and simple to operate, and working efficiency of the maintenance car is improved.

Description

technical field [0001] The invention belongs to the technical field of bridge maintenance, in particular to a bridge maintenance vehicle. Background technique [0002] At present, with the increasing number of bridge accidents at home and abroad, my country has paid more and more attention to the maintenance and maintenance of bridges. In order to have a comprehensive and objective understanding and evaluation of the current status of bridges, structural inspections are generally carried out first. If problems are found, It is also necessary to carry out maintenance work on the problematic parts. Since the bottom of the bridge is facing the air, it is difficult for the staff to be in place. In order to facilitate the inspection of the bottom of the bridge, various bridge inspection vehicles have been developed at home and abroad. [0003] At present, bridge inspection vehicles on the market can be roughly divided into three types: the first is a folding bridge inspection veh...

AI Technical Summary

Problems solved by technology

However, there are some inconveniences and deficiencies in the use of these two bridge inspection vehicles: (1) The hanging basket of the folding bridge inspection vehicle has a relatively small load and a relatively small working volume, and cannot carry large-scale inspection equipment, and the construction efficiency is relatively low. Moreover, due to the limitations of vehicle load capacity and body size, when the bridge deck is wide, the folding arm cannot extend the working platform to the middle of the bottom of the bridge, resulting in the inability to detect and construct the middle of the bridge bottom; (2) The two types of bridge inspection vehicles have a common The biggest problem is that when there are obstacles such as street light poles or cable stays installed on both sides of the bridge deck, in order to avoid obstacles, the working arm needs to be frequently retracted and lowered, and the staff also need to climb up and down, which consumes physical strength. The auxiliary time for inspection and maintenance is extended, and the construction efficiency is reduced; (3) Both inspection vehicles are equipped with counterweight trucks, and they occupy the lane during the construction process, which will not only affect the bridge traffic, but also increase the overall cost; and the first The three special bridge inspection vehicles have improved the shortcomings of the first two inspection vehicles to a certain extent. For example, they do not occupy the lane and will not affect traffic. The working platform is provided by hanging the basket with the boom, so that it cannot be avoided when encountering obstacles on the pier, and it is not suitable for some bridges crossing deep trenches and canyons, which has certain limitations.
