The invention discloses a rotary adjusting type lifting appliance structure for mounting an airport pavement slab. The rotary adjusting type lifting appliance structure comprises a lifting mechanism, the lifting mechanism comprises a lifting positioning mechanism and a supporting mechanism, the lifting positioning mechanism comprises an upper lifting frame, and the end part of the upper lifting frame is connected with a set of first lifting steering mechanisms. Each first lifting steering mechanism comprises a first rotating electromagnetic hydraulic cylinder assembly and a first steering bearing rod assembly, wherein one end of the first rotating electromagnetic hydraulic cylinder assembly is connected with the upper lifting frame, and the other end of the first rotating electromagnetic hydraulic cylinder assembly is connected with the upper end of the first steering bearing rod assembly. The supporting mechanism comprises a lower lifting frame, and lifting mechanisms are connected with the lower lifting frame through lifting positioning seats. The upper lifting frame is rotationally connected with the lower lifting frame through a lifting frame positioning rotating shaft assembly, a second servo push rod assembly is arranged on the lower lifting frame, and a cylinder shaft of the second servo push rod assembly is connected with the upper lifting frame. According to the lifting appliance structure, the airport pavement slab can be lifted more accurately and safely, and the structure is more stable.
