[0002] With the development of science and technology and the demand for space exploration, the functions of modern aerospace vehicles are becoming more and more diversified, and the structural size is getting larger and larger. At present, the mature aerospace vehicle manufacturing process generally adopts the form of segmented manufacturing and overall assembly. During the manufacturing process, the lifting, support, erection, and flipping of large sections of spacecraft have always been difficult problems in process design.

[0003] At present, the launch fulcrum of the aircraft is usually located at the tail end face of the aircraft, which plays the role of supporting the entire aircraft after the aircraft is erected and before launch. At this time, the erection load of the entire aircraft is transmitted from the tail end face to the nose through the aircraft body structure.

[0004] During the manufacturing process of aircraft, the support points and lifting points of large sections are mostly set separately, which increases the number of process lifting interfaces on the sections. The process lifting interfaces are numerous and require multiple sets of ground equipment and tooling to complete support and lifting work, which makes the tooling complex. In addition, the launch fulcrum is set on the tail end face, the force transmission path of the aircraft in the upright state is long, and the structure is heavy. Summary of the invention

[0009] Select two adjacent launching fulcrums at appropriate positions and connect them to the sling to realize the lifting action.

[0010] The hanger comprises a hook and a pin, the pin is passed through two ends of the hook, and the pin is adapted to the connecting hole.

[0011] During lifting, the pin of the lifting device passes through the connecting hole of the launching fulcrum, and the hook can rotate around the pin without the two being separated.

[0012] Two launching fulcrums set at relative positions are selected to be connected with the supporting tooling to realize the supporting action.

[0013] The supporting tooling comprises a supporting seat and a supporting pin shaft, the supporting pin shaft is penetrated through the supporting seat, and the supporting pin shaft is adapted to the connecting hole.
