Structural beam with high bearing capacity, bearing frame and assembly line

The utility model discloses a structural beam with high bearing capacity, a bearing frame and an assembly line, the structural beam comprises a hollow beam body, the hollow beam body is hexagonal, and reinforcing raised lines are arranged at the inner corners of the hollow beam body; the reinforcing protruding strips are connected with supporting plates, the tail ends of the supporting plates intersect in the middle of the hollow beam body to form a *-shaped supporting body, and the supporting plates and the reinforcing protruding strips are integrally arranged. Buffering holes are formed in the connecting positions of the reinforcing protruding strips and the hollow beam body, hole channels of the buffering holes are parallel to the outer surface of the hollow beam body, and the buffering holes are located in the sides, corresponding to the buffering holes, of the outer corners of the hollow beam body. The structural beam with the high bearing capacity is stable in structure and not prone to deformation when
