Abstract

The invention discloses a bridge deck height monitoring device and method based on laser ranging. The bridge deck height monitoring device comprises a laser range finder, a rotating mechanism and a balance connecting mechanism. The laser range finder comprises a laser range finding assembly. The laser range finding assembly comprises a housing, and a laser emitter and a laser receiver which are arranged at the front end of the housing. The rotating mechanism comprises a rotating table, a first gear set controlling the rotating table to rotate, a micro-rotating platform fixedly connected with the laser ranging assembly, and a second gear set controlling the micro-rotating platform to rotate. The inclination angles theta of all the laser ranging assemblies are integrally adjusted through thefirst gear set; the inclination angle theta of the single laser ranging assembly is adjusted through the second gear set; the change of the height of the bridge floor is measured in a manner of integrally combining with the movement of a single laser ranging assembly when the laser range finder is at the same inclination angle, and the change of the height of the bridge floor of the bridge is monitored in real time in a multi-point manner, so that timely measures are taken, and real-time detection and early warning of the bridge are realized.

Description

Technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge deck height monitoring device and method based on laser ranging. Background technique [0002] With the development of economy, highway and railway transportation are playing an increasingly important role in the national economy and people's lives. In order to adapt to the rapid development of the modern transportation industry, bridges are also extended to cross mountain streams, poor geology or to meet other transportation needs and erected to make traffic more convenient. [0003] As people pay more and more attention to the safety and durability of bridges, some key engineering bridges need to conduct periodic inspections of the actual operation of the bridges, provide experimental data for engineering design, and verify the structural analysis, calculation assumptions and design methods of the bridge design. Provide feedback information, and can be used for in-d...
