Stability Analysis of Underwater Pipeline Crawler

In order to improve the safety of underwater pipeline crawler in underwater operation and perfect its structural design, the stability of underwater pipeline crawler was studied. Firstly, the process of clamping the pipe with the clamping device of the crawler was divided into two stages: the clamping stage and the loading stage. Then the dynamic analysis was carried out, and the strength check of the V-shaped fixtures was accomplished. At last, the analysis results were summarized. The crawler mainly provides a platform for underwater pipeline operation equipment, which can be equipped with different equipment according to demand, providing convenience for underwater pipeline operation. Through simulation analysis and experimental verification have shown that the crawler meets the security requirements of underwater pipeline operations.
