Bridge inspection vehicle

Abstract

The invention relates to a device for bridge inspection, in particular a novel self-walking intelligent bridge inspection vehicle which comprises a lower carriage (8) and an upper carriage (10) connected with the lower carriage through a pivoting support (9), wherein the upper carriage (10) is connected with a vertical arm oil cylinder (16) at the upper end part of a vertical arm (17) through a quadrangular connecting and lifting mechanism, a rotating device (27) is arranged at the lower end part of the vertical arm (17) and connected with a horizontal working arm that extents to the bottom of a bridge, photographing devices are arranged on the rotating device (27) and the horizontal working arm, a frame oil cylinder (11) is arranged between the upper carriage (10) and the quadrangular connecting and lifting mechanism, and a connecting oil cylinder (19) is arranged between the rotating device (27) and a first telescopic arm (22). As the device is unmanned, the requirements to the structural strength of a cantilever crane are relatively smaller, thereby the volume and the weight of the bridge inspection vehicle are reduced, and the flexibility is enhanced; and meanwhile, an intelligent video device is adopted to store inspection videos, and the more specific analysis can be carried out conveniently, thereby the inspection result is more objective, and the inspection efficiency is higher.

Description

technical field [0001] The invention relates to bridge detection equipment, in particular to a novel self-propelled intelligent bridge detection vehicle. Background technique [0002] In order to discover and diagnose the health status of bridges in time, bridge inspection is the primary task of bridge operation and maintenance management. Since many parts of the bridge are not easy to approach, it is necessary to use the working platform provided by the bridge inspection equipment to complete the inspection work. The specific implementation is to use the bridge inspection vehicle to send the inspectors to the bottom of the bridge, and use the naked eye or inspection tools to detect defects. Most of the current bridge inspection vehicles are refitted from the chassis of General Motors. For the sake of personnel safety, the structural strength of the boom must be guaranteed, which leads to bulky equipment, high price and poor flexibility. At the same time, manual detection ...

AI Technical Summary

Problems solved by technology

Most of the current bridge inspection vehicles are modified from the chassis of General Motors. For the sake of personnel safety, the structural strength of the boom must be guaranteed, which leads to bulky equipment, expensive prices, and poor flexibility.

At the same time, manual detection is labor-intensive, there are potential safety hazards, the detection efficiency is low, and the results are somewhat subjective.
