Description

Technical Field

[0001] The utility model relates to a lean leveling tool for ship segment welding. Background Art

[0002] Ships are large in size and are basically built in sections and closed together on the slipway. During the closing process of the sections, the leveling of structural components such as bulb flat steel, T-profiles, and angle steel is involved. The traditional method is to use code plate welding to achieve leveling, and then cut the code plates and grind them after the section welding is completed, which is inefficient. Therefore, the applicant proposed a technical solution of a green shipbuilding codeless closing single-person special assembly tool and process, and obtained patent authorization with the authorization announcement number CN112722194B. The bulb flat steel leveling and closing device and the T-profile leveling and closing device involved in the solution still have some shortcomings. For example, there is no lateral adjustment rod on the right clamping plate of the bulb flat steel leveling and closing device, but in actual situation, the bulb flat steel is not always biased towards the side with the lateral adjustment rod, that is, the flat steel leveling and closing device has limitations in usage scenarios.

[0003] This solution was produced by further improving the original technical solution. Summary of the invention
