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.

Description

technical field [0001] The invention relates to a bridge detection and maintenance construction equipment, in particular to a hanger erected on sidewalks on both sides of the bridge, which can provide lifting points for the detection and maintenance work platform on the bottom of the bridge, and can avoid obstacles on the side of the bridge Articulated bridge maintenance vehicle. Background technique [0002] In order to provide a mobile operating platform for the maintenance of the underside of bridges with heavy traffic, the applicant filed a patent application number of 20121 with the State Intellectual Property Office on April 15, 2012, and the name of the invention is "A Hanger Articulated Bridge Maintenance Vehicle" , see Figure 1 to Figure 6 . The overhaul vehicle includes a frame car and a boom that can extend to the outside of the bridge. The frame car includes a frame chassis, and the boom is a C-shaped hanger. It is hinged with the lower end of a pillar, and th...
