Self-adaptive large-span space cable suspension bridge sling

The self-adaptive large-span space cable suspension bridge sling comprises an upper component, an upper inhaul cable, joint connectors, a lower inhaul cable and a stiffening beam which are sequentially connected from top to bottom, a groove is formed in the outer wall of the upper component, the upper inhaul cable is arranged in the groove, and the two ends of the upper inhaul cable are hinged to the joint connectors after the upper inhaul cable bypasses the upper component; the upper end of the lower inhaul cable is hinged to the lower end of the joint connector, and the lower end of the lower inhaul cable is hinged to the stiffening beam. The hinged central axis of the upper inhaul cable and the joint connector intersects with the hinged central axis of the lower inhaul cable and the stiffening beam. Self-adaptive large-angle rotation in the transverse bridge direction and the longitudinal bridge direction can be achieved, the large-angle deflection requirement of a large-space cable ground anchor type susp
