UNDERWATER DISASSEMBLY AND ASSEMBLY MODULE FOR DEDICATED SHACKLE
Document Type and Number:
WIPO Patent Application WO/2021/109360
Kind Code:
A1
Abstract:
An underwater disassembly and assembly module for a dedicated shackle comprises: a lateral pin disassembly and assembly module (2) and a nut disassembly and assembly module (3). The lateral pin disassembly and assembly module (2) comprises a lateral pin sleeve (2-1), a ROV lateral pin handle (2-2), a lateral pin stopper pin (2-3), a ROV lateral pin retaining pin (2-4), a lateral pin (2-5), and a roller bearing (2-6). The nut disassembly and assembly module (3) comprises a nut (3-1), a ROV nut handle (3-2), a nut sleeve (3-3), a nut retaining pin (3-4), a guide rail (3-5), a ROV sliding block retaining pin (3-6), a sliding block (3-7), a ROV sliding block handle (3-8), a nut stopper pin (3-9). The present structure ensures that ROV robots achieve an underwater disassembly and assembly function, and meet requirements for connection performance and use performance while facilitating assembly and disassembly operations, thereby completing underwater installation tasks simply by pushing, pulling, and rotating operations, and are reusable.
