Description

Technical Field

[0001] The present application relates to the technical field of installation of external cables of bridges, and in particular to a cable guide device for installing external cables. Background Art

[0002] Bridge flexural cables are a device used to reinforce bridges, primarily for the reinforcement and renovation of existing bridges. They are a crucial component of post-tensioning systems, strengthening bridges by applying prestress to the components using prestressed strands located outside the main cross-section of the component. This technology leverages the high strength and elastic modulus of steel strands and carbon fiber sheets to provide flexural reinforcement, thereby improving the bridge's strength, rigidity, and stability. During the flexural cable installation process, a cable guide is required to accommodate cable structures with varying inclination angles, avoid damage during installation, and extend the cable's service life.

[0003] Existing cable guides primarily consist of a bracket and supporting rollers. The supporting rollers are mounted in the bracket's cavity. The cable passes through the bracket's opening and exits through the supporting rollers. The supporting rollers are fixed in position. When used in pairs, the distance between the two rollers is fixed, making them unable to accommodate cables of varying thicknesses. Smaller cables can wobble, exacerbating cable wear.
