The invention discloses a door body opening and closing linkage device. The back face of a first linkage support and the back face of a second linkage support are connected with a main steel wire rope in the upward direction and the downward direction correspondingly, so that a left slow door hanging plate and a right slow door hanging plate are linked, a left rapid door hanging plate and a right rapid door hanging plate are in linkage with the left slow door hanging plate and the right slow door hanging plate through a first linkage steel wire rope wheel assembly and a second linkage steel wire rope wheel assembly respectively, and therefore the four door hanging plates form a linkage structure to act together. The invention further provides a door body self-closing linkage device. Opening and self-closing of a fireproof door can be achieved, and the device can also be applied to other door bodies.
