The invention relates to an anti-fraying and waterproof sling structure of a suspension bridge. The structure comprises a sling body (15), a female cone (9), an ear plate (6) of a steel box girder and a main cable clip (1). Steel wires (10) at the end part of the sling body (15) are divided and inserted into the female cone (9), a coupling sleeve (16) is arranged at the rear part of the female cone (9), internal threads are arranged at the front end of the female cone (9), the internal threads are connected with the ear plate (6) of the steel box girder through threads, the ear plate (6) of the steel box girder are connected with the main cable clip (1) by adopting a pin (3), a shaft housing (19) is mounted among the hole of the main cable clip (1), the hole of the ear plate (6) and the pin (3), the shaft housing (19) is provided with a high-strength metal substrate (19.1), a plurality of through holes are arranged on the surface of the shaft housing (19) in sequence, solid lubricants (19.2) are embedded inside the through holes, the substrate (19.1) is made of tin bronze, and the solid lubricants (19.2) are made of graphite; and a pin protecting cover (4) is mounted at the end part of the pin (3). The sling structure is anti-fraying and waterproof, so that the safety and reliability of the suspension bridge can be improved, and the replacement frequency of the sling can be reduced.
