4. The damping device according to claim 3 , wherein:
the steel wire rope is wound round the upper connecting member and the lower connecting member, and the steel wire rope includes a plurality of elastic portions exposed between the upper connecting member and the lower connecting member, or
the steel wire rope is a first steel wire rope, and the steel wire rope damper further includes a second steel wire rope, wherein:
two ends of each of the first steel wire rope and. the second steel wire rope are fixedly connected with the upper connecting member and the lower connecting member, respectively, or
each of the first steel wire rope and the second steel wire rope is wound around the upper connecting member and the lower connecting member.

5. The damping device according to claim 3 , wherein the steel wire rope includes a plurality of elastic portions exposed between the upper connecting member and the lower connecting member, the elastic portions being distributed in central symmetry or axial symmetry between the upper connecting member and the lower connecting member.

6. The damping device according to claim 3 , wherein the upper damping connecting member comprises a plurality of upper connecting portions distributed in central symmetry or axial symmetry, at least one of the upper connecting portions being configured to connect the upper damping connecting member with the steel wire rope damper.

7. The damping device according to claim 6 , wherein:
the upper damping connecting member comprises a cross-shaped plate, and end portions of the plate form the upper connecting portions, or
the upper damping connecting member comprises a circular plate, and the plurality of upper connecting portions are evenly disposed at a peripheral edge of the plate, or
the at least one of the upper connecting portions is fixedly connected with the steel wire rope damper through an upper connecting shaft, and the upper connecting shaft is disposed in parallel to elastic portions of the steel wire rope exposed between the upper connecting member and the lower connecting member.

8. The damping device according to claim 3 , wherein the lower damping connecting member comprises a plurality of lower connecting portions distributed in central symmetry or axial symmetry, at least one of the lower connecting portions being configured to connect the lower damping connecting member with the steel wire rope damper.

9. The damping device according to claim 8 , wherein:
the lower damping connecting member comprises a cross-shaped plate, and end portions of the plate form the lower connecting portions, or
the lower damping connecting member comprises a circular plate, and the plurality of lower connecting portions are evenly disposed at a peripheral edge of the plate, or
the at least one of the upper connecting portions is fixedly connected with the steel wire rope damper through a lower connecting shaft, and the lower connecting shaft is disposed in parallel to elastic portions of the steel wire rope exposed between the upper connecting member and the lower connecting member.

10. The damping device according to claim 1 , wherein the carrying damper comprises:
a lower adaptor fixedly connected with the upper damping connecting member;
an upper adaptor opposite to and spaced apart from the lower adaptor; and
a damping elastic member connected with the upper adaptor and the lower adaptor.

11. The damping device according to claim 10 , wherein:
the steel wire rope damper is one of a plurality of steel wire rope dampers included in the damping device, the plurality of steel wire rope dampers being distributed in central symmetry, and
