Suspension cable of space cable rope structure

The invention discloses a sling for a spatial cable structure, which comprises a sling body, an upper-end anchorage connected with the upper end of the sling body, and a lower-end anchor device connected with the lower end of the sling body, wherein the lower-end anchor device comprises a lower-end anchorage, a connecting rod, a base and a revolute pair positioned between the connecting rod and the base, the connection rod is a long rod with a cylinder head on the lower end, the revolute pair is a ring-shaped ball support with an inner spherical surface as the end surface of one end, the base is a tower-shaped body with a step hole, a small upper end and a large bottom end, the end surface of the bottom end of the base is an inclined surface or a plane, the upper end of the connecting rod passes through the step hole of the base and is connected with the lower-end anchorage, the cylinder head on the lower end of the connecting rod is locked on the end surface of the inner spherical surface of the revolute pair in the step hole of the base, and the lower end of the sling body is in anchoring connection with the lower-end anchorage of the lower-end anchor device. The sling can rotate larger angles, move, extend, and be adjusted with the length, and can fully adapt the demand of a suspension bridge adopting spatial cables to the structural form of the sling.
