Description

Technical Field

[0001] The utility model relates to the technical field of sealed cabin section disassembly and assembly, in particular to a sealed cabin section disassembly and assembly tool. Background Art

[0002] At present, the compartments of sealed compartments such as underwater vehicle hulls are sealed by O-rings, and then directly connected and fixed by hoops, wedges or screws. This kind of sealed connection structure has high requirements for the installation accuracy of the two compartments. During assembly, the two compartments need to be axially aligned to ensure a certain coaxiality, and they need to be pre-installed in place with the help of external force, and then fastened with connectors. At present, the assembly of sealed compartments usually uses slings to assist manual alignment and installation, which is difficult to operate; or it is installed on a fixed assembly platform, which has high requirements for site support facilities.

[0003] It is installed using slings and assembly platforms, and sealing structures such as bevel seals can be pre-assembled into place by manual pushing. For radial sealing structures, the extrusion and deformation of the O-rings produce great friction, and normal push-pull assembly is basically impossible to achieve by manual force. Chinese patent applications CN202211425047.3, a cabin assembly tool for underwater vehicles, CN202122574703.3, a cabin connection tool, and CN202311466794.6, a pressure-resistant disassembly tool for underwater vehicles, respectively disclose tools for cabin assembly and disassembly, but these tools still need to be hoisted for heavier cabins or adjust the axial position with the help of an assembly platform, and it is difficult to ensure the stability and smoothness of the assembly process, and it is easy to damage the sealing ring or the assembly process.
