Abstract
A fast-splicing type large-span bridge detecting and reinforcing operation platform comprises a fast-splicing truss beam which is spliced by a plurality unit modules. The lifting ends at two ends of the fast-splicing truss beam adopt cable structure anchoring systems. Two anchoring ends are disposed on the middle section of the fast-splicing truss beam. Two pairs of inhaul cables are transversely symmetrically disposed on the fast-splicing truss beam. Each cable structure anchoring system comprises a fixing support fixed on the truss beam and a tensioning mechanism mounted on the fixing support. A sleeve type spiral cable tensioning device is disposed at each tensioning mechanism. A pressure ring is mounted at each anchoring end. One ends of inhaul cables respectively penetrate the spiral cable tightening device to be connected with the tensioning mechanism, and the other ends thereof respectively penetrate pressing rings to be connected with the anchoring ends. The fast-splicing type large-span bridge detecting and reinforcing operation platform has the advantages that the inhaul cables are added to an existing hanging basket structure, mid-span deflection and mid-span moment can be reduced effectively by increasing the pre-tension of the inhaul cables, structural bearing cavity is increased, and large span is achieved.
