In deep-sea mixed transmission mining systems, the mixed transmission hard pipe plays an important role in mineral transport. To speed up the process of connecting the hard pipe, a quick disassembly and assembly system was designed. By model analysis, the key focus of the rapid disassembly and assembly system was the clamp connector. On the basis of vibration theory and finite-element simulations, the connector underwent static and vibration analysis, and the fatigue life was predicted. Finally, laboratory and sea test tests were conducted on the rapid disassembly and assembly system. The quick disassembly and assembly system can realise quick disassembly and assembly under the target working conditions and maintained smooth operation during two 24-h cycle tests.
