The conventional spacecraft cabin lifting accessory is mostly connected with the cabin end frame only, the load diffusion efficiency of the mode is very low, and the lifting load is concentrated at a lifting point, so that the design requirement on the cabin end frame is high and the bearing capacity is low; in addition, a large additional bending moment is generated at the hanging point, the requirement on the mechanical property of the end frame is high, and the structural weight of the cabin body is increased by a reinforced design. With the research and development of heavy-duty aerospace equipment, the load borne by a spacecraft cabin and a hoisting accessory is larger and larger, and the current connection mode of the hoisting accessory cannot meet the requirement of the hoisting load.
