Description

Bridge sling fork ear end anchor

Technical Field

The utility model relates to the field of cables, in particular to an anchor for a fork ear end of a bridge sling.

Background

In recent years, with further research on the aesthetic of bridges, space cable suspension bridge structures with attractive shapes and unique structures are widely used. The space cable suspension bridge adopts a space structure in the shape of a main cable line, and the projection of the main cable on a vertical surface and a plane is curved. Therefore, for a space cable structure suspension bridge, there are 3 displacements in the vertical, horizontal and vertical directions during construction. In the construction process from the empty cable state to the bridge forming state, the sling is matched with an anchor, so that the requirement of rotating a large angle in a three-dimensional space is met. Because the suspension bridge with the space cable structure requires that the sling can rotate and stretch according to construction requirements in the construction process from an empty cable state to a bridge forming state.

At present, after the anchor is connected with the cable, the anchor swings in all directions together with the cable, and one end of the anchor is fixed, so that the connection position of the anchor and the cable is more easily worn, and the service life of the anchor is influenced. Therefore, there is a need for an improvement in such a structure to overcome the above-mentioned drawbacks.
