AI Technical Summary

Technical Problem

Existing wrapping devices use fixed-size clamping structures and preset wrapping trajectory parameters, resulting in poor equipment adaptability, affecting the tightness and uniformity of wrapping, and making them unsuitable for cables of different diameters.

Method used

The system employs a rotating cage structure, a traveling structure, and a wheeled structure. The rotating cage structure can be fitted onto the outside of the bridge tower's steel cables. The traveling structure is connected to the rotating cage structure and set at an angle. The wheeled structure is used for attaching and wrapping the film and backing film. By adjusting the traveling speed and the number of rotations, the wrapping density is controlled, achieving uniform wrapping of the film and gathering of the backing film.

Benefits of technology

It effectively controls the wrapping density, avoids the backing paper from winding randomly, improves the tightness and uniformity of the wrapping, adapts to cables of different diameters, and enhances construction efficiency and safety.

Abstract

This invention provides a cable wrapping machine for bridge tower steel cables, relating to the technical field of cable wrapping. It includes a rotating cage structure, a traveling structure, and a pulley structure. The rotating cage structure is fitted onto the outside of the bridge tower steel cable. The traveling structure has multiple sets, all connected to the rotating cage structure, and is inclined at an angle to the bridge tower steel cable so that the rotating cage structure travels along the extension direction of the bridge tower steel cable while rotating. The pulley structure has two sets, both connected to the rotating cage structure. The first set of pulleys has a coated paper and is used to attach the film of the coated paper to the surface of the bridge tower steel cable while the rotating cage structure is traveling. The second set of pulleys is used to wrap the backing paper after the film has separated. This invention alleviates the technical problem in the prior art where the use of fixed-size clamping structures and preset winding trajectory parameters results in poor equipment adaptability and thus unsatisfactory performance.
