Anchoring semitrailer chassis for tethering and transition transporting of large tethered balloons

The invention discloses an anchoring semitrailer chassis for tethering and transition transporting of large tethered balloons. The anchoring semitrailer chassis comprises a tractor, a bearing compartment frame, a detachable suspension system, a rotating table and a plurality of supporting legs. During transporting, the tractor and the bearing compartment frame are pulled for transporting through traction pins, the detachable suspension system is assembled at the bottom of the bearing compartment frame, and the rotating table is located in the middle of the bottom of the bearing compartment frame; and during erecting, the detachable suspension system is detached to be disengaged from the tractor, the supporting legs are mounted on the rotating table, and the bearing compartment frame rotates along a central line of the rotating table. The constraint and limitation of a traditional chassis longitudinal beam structure to the design of the rotating table are removed, the degree of freedomof the design of the rota
