Abstract:
The present invention relates to the technical field of converter valve bushing blocking structures, and provides a keel structure and a blocking system, which avoid cracks at mounting holes for mounting of first fasteners in a blocking plate. The keel structure comprises: a transverse supporting assembly comprising a first supporting piece, at least one side of which is provided with a first recess, the first recess and a blocking plate being suitable for defining a deformation chamber allowing first fasteners to deform, the first fasteners penetrating through the blocking plate and the first supporting piece in the depth direction of the first recess, so as to suspend the middle portion of the blocking plate from the first supporting piece, and the middle portions of the first fasteners being located in the deformation chamber; and a vertical supporting assembly comprising a second supporting piece and a third supporting piece, the second supporting piece being connected to a first surface of the first supporting piece, the third supporting piece being connected to a second surface of the first supporting piece, the first surface and the second surface being two opposite surfaces adjacent to the opening of the first recess, and the second supporting piece and the third supporting piece being staggered from the first supporting piece. The keel structure is used for supporting the blocking plate.
