The invention discloses a method for turning over an irregular U-shaped total section of a chemical ship. The method includes the following steps that firstly, auxiliary parts are welded to the U-shaped total section; secondly, in the state of U-shaped total section inversion, a C-shaped lifting ring is used as a main hook, a B-shaped lifting ring is used as an auxiliary hook, the U-shaped total section is turned at 90 degrees clockwise, and the U-shaped total section is suspended and turned into a lateral state; thirdly, a docking block is placed on a working platform before the U-shaped total section is suspended and turned into the lateral state, a straight section of a starboard of the U-shaped total section and the supporting end protruded from a circular tube are located on the docking block, and thus the straight section of the starboard of the U-shaped total section and the supporting end protruded from the circular tube are on the same horizontal plane, and fourthly, the C-shaped lifting ring is used as the auxiliary hook, the B-shaped lifting ring and a D-shaped lifting ring are used as the main hook, the U-shaped total section is continuously turned at 90 degrees clockwise, the U-shaped total section is suspended and turned into an ortho state, and the U-shaped total section is suspended into a berth for carrying. According to the method for turning over the irregular U-shaped total section of the chemical ship, through combination of the docking block and steel pipes, the irregular U-shaped total section is laid in a lying state, stability of the U-shaped totalsection is ensured, and occurrence of safety accidents is avoided.
Description
Technical field [0001] The invention belongs to the field of ship construction, and particularly relates to a method for turning over an irregular U-shaped total section of a chemical tanker. Background technique [0002] In the construction of ships, especially chemical tankers, there are a large number of U-shaped general sections in the cargo hold section. The mid-hull part is generally a regular U-shaped section. The U-shaped general section near the bow and stern is caused by the tightening of the line. Part of the total section is an irregular U-shaped total section. If such a general section is like an ordinary U-shaped general section that can be turned over to a lying state and placed on the dock, it will cause the general section to overturn and cause serious safety accidents. Summary of the invention [0003] In view of the problems in the prior art, the present invention provides a method for turning over the irregular U-shaped main section of a chemical tanker. The p...
