[0035] The embodiment of the present application provides a transverse bulkhead section loading method, which adopts the transverse bulkhead section loading auxiliary device of any one of the above embodiments, and the method comprises the following steps:

[0036] The transverse bulkhead section is converted into a continuous whole.

[0037] The loading auxiliary device is installed on the inner bottom plate of the corresponding double-bottom section of the transverse bulkhead section at a preset position, and the preset position is determined according to the plate thickness of the corresponding preset position of the transverse bulkhead section and the internal structure of the double-bottom section.

[0038] After the transverse bulkhead section is hoisted horizontally and turned over by 90 degrees, the lower end of the aft bulkhead is positioned by sliding along the inclined surface of the installed loading auxiliary device.

[0039] After the transverse bulkhead section is released from the quick release hook scheme, the hoisting equipment is removed, the transverse bulkhead section is welded, and the loading is completed.

[0040] The embodiment of the present application provides a transverse bulkhead section loading method of a super-large container ship, and the method comprises the following steps:

[0041] Step 1, planning a loading scheme of the transverse bulkhead section of the super-large container ship. Figure 3As shown, the transverse bulkhead sections of ultra-large container ships extend vertically from the inner bottom plate of the double bottom to the transverse hatch coaming, spanning the entire width of the ship. The lower structures of the bow and stern bulkheads are transversely discontinuous. Therefore, the assembly scheme for the transverse bulkhead sections of ultra-large container ships includes rapid positioning and rapid hook-off. Rapid positioning requires aligning the internal structure (i.e., transverse ribs) of the bow and stern bulkhead sections with the reverse side of the inner bottom plate of the double bottom. Rapid hook-off requires, under safe conditions, fixing the transverse bulkhead sections, releasing the hooks of the lifting equipment, and then welding the transverse bulkhead sections to complete the assembly. The rapid positioning scheme for the transverse bulkhead sections first requires connecting the lower ends of the bow and stern bulkheads of the sections using profiles to form a transversely continuous structure, ensuring continuity and integrity. Secondly, it requires the use of assembly auxiliary devices to guide and position the transverse bulkhead sections. The rapid unhooking scheme for the transverse bulkhead section is achieved by installing restraint plates at the lower ends of the bow and stern bulkheads of the transverse bulkhead section and by using restraint welding at the bilge step positions.

[0042] Step 2: Design auxiliary equipment for mounting the transverse bulkhead section. Based on the rapid positioning scheme in the mounting plan for the transverse bulkhead section of the ultra-large container ship planned in Step 1, design the following... Figure 1 The auxiliary mounting device is shown. Based on the finite element analysis results and the installation of outfitting components, the specifications and installation positions of the profiles that achieve structural continuity at the lower ends of the bow and stern bulkheads were determined, as were the width, height, and thickness parameters of the auxiliary mounting device. To achieve a guiding function, the angle of the auxiliary mounting device needs to be designed. Through holes are designed into the structure to facilitate the storage and transfer of the auxiliary mounting device. Furthermore, to prevent the auxiliary mounting device from affecting the mounting of the transverse bulkhead section, a chamfer is designed, which must meet the weld leg height requirements of the transverse bulkhead section mounting corner joint.

[0043] Step 3: Install auxiliary equipment on the transverse bulkhead section. For example... Figure 2 As shown, the mounting auxiliary device designed in step 2 is installed. The mounting auxiliary device is installed only on the stern bulkhead of the transverse bulkhead section, with its inclined surface facing the stern bulkhead of the transverse bulkhead section. As... Figure 1 As shown, three auxiliary devices are installed, one at the centerline and the other two symmetrically arranged to the left and right. The beam direction is aligned with the strong structure of the transverse bulkhead, and the length direction is determined by the reverse rib structure of the double bottom section corresponding to the transverse bulkhead, combined with the alignment line between the transverse bulkhead and the double bottom section, and the thickness of the bulkhead plates at the corresponding positions of the transverse bulkhead. Figure 3 As shown, the installation of the auxiliary device is completed ahead of schedule during the double-bottom segment manufacturing stage.

[0044] Step 4, the transverse bulkhead section is hoisted and then turned over by 90°, and the lower end of the transverse bulkhead section is guided to slide along the inclined surface of the transverse bulkhead section loading auxiliary device installed in step 3, and then falls on the inner bottom plate of the double bottom, and is accurately positioned. After the transverse bulkhead section is loaded and quickly positioned, the hooks of the hoisting device are still in a stressed state to ensure safety. Figure 4 As shown in FIG. 1, according to the quick unhooking scheme for loading planned in step 1, a restraint plate is installed at the lower end of the bow and stern bulkheads of the transverse bulkhead section, and a constraint welding is performed at the bilge step position. The restraint plate has minimum height and width requirements, is aligned with the strong structure of the transverse bulkhead section, and is welded between the stern bulkhead and the inner bottom plate of the transverse bulkhead section, and the welding length should not be less than a specific length. The constraint welding before and after the bilge step position is symmetrically arranged, and the constraint welding length should not be less than a specific length. After the quick unhooking scheme for loading is implemented, the transverse bulkhead section is unhooked, the hoisting device is removed, the transverse bulkhead section is welded, and the loading is completed.
