Freely-located intelligent bridge bottom inspection maintenance vehicle

Abstract

The invention discloses a freely-located intelligent bridge bottom inspection maintenance vehicle which comprises guide rails, walking mechanisms, a rotary disc, a truss, telescopic arm structures andan electrical control system. The two guide rails are installed in parallel at the bottom of a bridge in the longitudinal bridge direction, the four walking mechanisms are symmetric in pairs and aresuspended on the two guide rails and arranged at the two ends of the rotary disc, the rotary disc is arranged among the four walking mechanisms and the truss, the truss is arranged at the bottom of the rotary disc and horizontally rotates at 90 degrees relative to the guide rails under rotation of the rotary disc, and the two telescopic arm structures are arranged at the two ends of the truss; andthe electrical control system is arranged on the middle portion of the truss and electrically connected with the walking mechanisms, the rotary disc and the telescopic arm structures and communicateswith the walking mechanisms, the rotary disc and the telescopic arm structures through hydraulic oil pipelines. The mode that the bridge bottom inspection maintenance vehicle is hydraulically drivento rotate to pass a pier is mainly adopted, detection maintenance of a multi-span continuous bridge is achieved, and the freely-located intelligent bridge bottom inspection maintenance vehicle has theadvantages of being good in adaptability, high in freedom degree, high in efficiency, good in economical efficiency and the like.

Description

technical field [0001] The invention relates to a bridge inspection vehicle, in particular to a free-positioning intelligent beam bottom inspection and maintenance vehicle. Background technique [0002] Bridge construction is one of the important infrastructures of the country, and bridge engineering is a lifeline project related to the coordinated development of society and economy. With the increase of bridge service time, due to the long-term impact of unfavorable factors such as environmental loads, fatigue effects, corrosion effects and material aging on bridge facilities, bridge structures will inevitably produce various types of fatigue such as natural aging and damage accumulation. In order to ensure the normal use of the bridge, it is necessary to detect and maintain the bridge in a timely and effective manner. [0003] The traditional beam bottom inspection vehicle is generally designed as a horizontal beam structure according to the structural form of the bridge....
