AI Technical Summary
Technical Problem
The high-level assembly of the second-level platform of the offshore oil drilling rig tower is risky and inefficient, affecting normal operation and production efficiency.
Method used
The auxiliary assembly tooling is used to simulate the positioning dimensions and angles of the derrick column. The assembly platform is fixed by connecting the base plate, and the side beams and platform are connected by bolts. Finally, it is transported and fixed to the derrick position by a crane, and assembled in combination with diagonal braces and fixing rods.
Benefits of technology
It reduces the risks of high-level assembly, improves assembly accuracy and efficiency, and saves production costs.

Abstract
本发明公开了一种海洋石油钻机塔形井架二层台的低位组装方法，通过模拟海洋石油钻机塔形井架的四个立柱加工四个相应的辅助组装工装，将四个辅助组装工装固定在组装平台上，进行海洋石油钻机塔形井架二层台的组装，二层台组装完成后通过吊机将二层台运送到海洋石油钻机塔形井架相应的高度后通过螺栓连接。本发明通过加工四个辅助组装工装完成海洋石油钻机塔形井架高位组装台体的低位组装，既满足了该类型海洋井架的通用性，降低了复杂高位空间组装式台体的组装风险，保证了组装精度，同时也节约了组装生产制造成本。
