Hanging bracket hinge joint type bridge maintenance vehicle capable of avoiding bridge-side obstacles

Abstract

The invention provides a hanging bracket hinge joint type bridge maintenance vehicle capable of avoiding bridge-side obstacles. The hanging bracket hinge joint type bridge maintenance vehicle comprises a vehicle frame and a suspension arm, wherein the vehicle frame comprises a vehicle frame chassis (21), the suspension arm is a C type hanging bracket (25), the vehicle frame chassis (21) is in hinge joint with the lower end of a strut (23) by a longitudinal shaft hinge (22) and a longitudinal shaft, an extending end of a lower transverse beam of the C type hanging bracket (25) is provided with at least one of lifting rope fixing points (26) or lifting rope winding / unwinding devices, a vehicle frame longitudinal beam (44) is fixed at the upper end of the strut (23), a hanging bracket longitudinal beam (42) is fixed at the upper end of a vertical rod of the C type hanging bracket (25), and the hanging bracket longitudinal beam (42) and the vehicle frame longitudinal beam (44) are movably connected with each other into a whole by at least two of transverse beams (41). The hanging bracket hinge joint type bridge maintenance vehicle is simple in structure, can conveniently avoid the obstacles, is convenient to construct, is labor-saving and time-saving, does not need adding equipment, can not occupy lanes, can not influence the traffic on the bridge floor, and is good in adaptability to the bridge, and the construction efficiency of the maintenance vehicle can be improved.
