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.

    本发明公开一种门体开闭联动装置,通过第一联动支架的背面、第二联动支架的背面分别与主钢丝绳上行、下行连接,从而使左慢门门挂板、右慢门门挂板联动,而左快门门挂板、右快门门挂板分别通过第一联动钢丝绳轮组件、第二联动钢丝绳轮组件,与左慢门门挂板、右慢门门挂板联动,从而使四块门挂板形成联动结构一起动作。本发明还提供一种门体自闭联动装置。可以实现防火门的开启与自闭,也可以应用于其它门体。
