Detection vehicle device for bridge damage diagnosis method based on axle coupling system

Abstract

The invention belongs to the technical field of bridge detection devices, particularly to a detection vehicle device for a bridge damage diagnosis method based on an axle coupling system. The detection vehicle device includes a movable trolley which can move on a bridge to be detected; a signal pickup device used for picking up a vibration signal transmitted by the bridge to be detected to the movable trolley; and a signal collection device connected with the signal pickup device and collecting the vibration signal picked up by the signal pickup device. The detection vehicle device for the bridge damage diagnosis method based on the axle coupling system can comprehensively, effectively and accurately acquire a bridge response signal in real time, thereby satisfying the requirements of the bridge damage diagnosis method based on the axle coupling system.

Description

technical field [0001] The invention belongs to the technical field of bridge detection devices, in particular to a detection vehicle device for a bridge damage diagnosis method based on a vehicle-bridge coupling system. Background technique [0002] With the rapid development of the national economy and the continuous deepening of the urbanization process, the country pays more and more attention to the construction of transportation infrastructure. As the "throat" connecting traffic engineering, the importance of bridge structure is self-evident. As an important part of the "lifeline" project, the bridge structure is crucial to normal transportation and disaster prevention and relief, so the requirements for its safety, durability and normal use function are getting higher and higher. [0003] But on the one hand, in the construction process of the bridge structure, due to problems such as material inhomogeneity and construction accuracy, there will be deviations in the d...

Problems solved by technology

In addition, the existing detection methods often need to interrupt the bridge traffic, otherwise the noise of other traffic vehicles will cause serious interference, that is to say, the kinetic energy of the bridge will be zero during the detection period, which will cause serious capacity loss and put pressure on local traffic , so, how to accurately detect the bridge without interrupting the bridge traffic without being disturbed by the surrounding traffic noise has always been a technical problem in this technical field
