Meanwhile, the suspension box body 10 is composed of a truss layer 8 and a suspension layer 9, the truss layer 8 is in full-welded connection with the core barrel 7, and the suspension layer 9 is hinged with the core barrel 7, so that the suspension layer 9 is pulled through the suspension posts and part of the weight of the suspension layer is upwards transferred to the truss layer 8 through the suspension posts, and the integral downward suspension of the suspension layer 9 is further realized. Furthermore, each suspension box 10 has only one truss layer 8, and the number of suspension layers 9 of each suspension box 10 is different.
