Abstract

Due to the effect of the marine environment, the marine pipelines would drift away because of the water buoyancy when the pipeline laying and operation, as well as suffer the damage from the other external factors. Therefore, we need to coat a concrete layer on the anticorrosive pipe’s surface with a certain thickness after the steel cage installed process, namely marine pipeline concrete weight coating (CWC). The concrete coating is the most important section of the marine pipeline CWC process. It’s also the key to guarantee the pipe quality. Besides, the projectile device is the significant equipment of pipeline coating, and its performance would directly affect the safety, stability and reliability of coating process, as well as the CWC quality. Through the research of the projectile process at home and abroad, a new vertical projectile method has been proposed. Based on this, we design the concrete projectile system. Therein, the mechanical part of the whole projectile system has been designed. Firstly, the strength and rigidity of the key components of the projectile wheel sets have been checked with the software ANSYS. The check results meet the design requirements. The natural frequency of the projectile bench is determined by the modal analysis. And then we could find out the effect of the motor frequency acting on the resonance damage. According to the above research results, a series of improving methods have been proposed.
