Reverse side reinforcing structure and reinforcing method for chain stopper installation

The invention discloses a reverse side reinforcing structure and method for chain stopper installation in the technical field of ships. The reverse side reinforcing structure comprises a chain stopper arranged on a deck, the chain stopper comprises a base and a rotating shaft arranged on the base, the base comprises two toggle plates welded to the deck, reinforcing ribs are arranged at the positions, close to the toe ends of the toggle plates, of the lower portion of the deck, the reinforcing ribs are welded and fixed perpendicular to the deck, and the reinforcing ribs extend in the axial direction perpendicular to the rotating shaft. The length range of the reinforcing ribs is larger than or equal to the moving range of the toggle plate moving back and forth in the axial direction perpendicular to the rotating shaft. The method has the advantages that the reinforcing ribs can be mounted at the indoor stage to enhance the strength, and the working efficiency is improved. 本发明公开了船舶技术领域的一种挚链器安装的反面加强结构及加强方法。该反面加强
