Abstract
The superstructure construction of a suspension bridge is a critical phase in bridge erection,and its efficiency directly affects the overall project schedule.Main-cable traction,strand insertion into saddles,and main-girder installation have traditionally relied on manual labor and conventional machinery.This approach entails excessive human intervention,low construction efficiency,and a low level of intelligence,making it difficult to satisfy present demands for intelligent bridge construction.To address the intelligent hoisting of equipment during suspension bridge superstructure construction,a rapid traction mechanism was developed to control high-speed main-cable traction,and a cable saddle installation robot was developed to efficiently shape the main cable and insert it quickly into the saddle.Subsequently,the intersection segment of cable and girder was erected by combining a split cable crane with a bridge cable crane.Full-scale field application of the integrated equipment shows that main-cable traction efficiency increases by 40%and strand-in-saddle efficiency increases by 60%,solving the erection problem of segmental girders at the cable-girder intersection.关键词
