| Abstract: | According to the lifting requirements of steel pile of offshore jacket platform,the paper presents a design of internal lifting pile based on bevel increasing-force theory and discusses the lifting principle in detail.Based on the dynamic simulation of lifting process,the structure and material performance of the gripping button is studied.The FEM analysis of contact process between the gripping buttons and the steel pile is done by the shear-friction theory.The indentation depth on the inside surface of the pile is gained.The final load experiment shows that the internal lifting tool presented in the paper can ensure the safety and reliability of lifting large steel piles. |
