Connecting device provided with pluggable pin shaft and used for hoisting large-size heavy object and sling

The utility model relates to the field of large-size heavy object hoisting connecting structures in constructional engineering, in particular to a large-size heavy object and sling connecting device containing a pluggable pin shaft and used for hoisting, and the large-size heavy object and sling connecting device comprises a connecting assembly and an auxiliary assembly. The connecting assembly comprises a connector arranged on the sling, a connecting column arranged on a hoisted object and a pin shaft used for enabling the connector and the connecting column to be connected with each other. The auxiliary assembly is used for applying acting force to the hoisted object and installed on the connector. The connection between the hoisted object and the sling is realized through the pin shaft, the connection stability between the sling and a large-size heavy object can be improved, and the possibility of falling of the large-size heavy object in the hoisting process is reduced, so that the safety of building cons
