摘要
海上钻井平台上吊机吊臂传统维修方法不仅维修费用高,而且费时费力,针对吊臂维修中存在的这些缺点,开展了对吊臂校正关键技术的研究与可行性分析,提出了一种全新的技术方案,旨在实现吊臂校正而无需拆卸受损部件。为验证该技术方案的可行性,进行了三维建模和有限元分析仿真,并在工厂进行试验。有限元仿真期间固定未变形吊臂两端,施加顶升力在变形处。在工厂实际试验时也是基于上述原理,通过液压装置固定吊臂,然后通过液压顶升系统在变形处施加顶升力。有限元仿真表明,当施加顶升力达到40 t时,变形的吊臂会逐步恢复。工厂试验时,当施加顶升力达到39.1 t时,吊臂开始逐步恢复,误差为0.0225,验证了有限元仿真的准确性。基于以上理论,针对KL10-1F平台吊机吊臂与WC19-1平台吊臂开展校正工作,这两次校正工作的圆满完成,验证了在不拆卸吊臂情况下,是可以通过液压顶升装置完成校正的。这两个成功案例不仅为该平台的后续作业提供了有效支持,也为今后其他海上钻井平台在进行类似吊机维修时提供了重要的指导和借鉴。
The traditional maintenance method of crane boom on offshore drilling platform is not only expensive,but also time-consuming and laborious.In view of these shortcomings in boom maintenance,the research and feasibility analysis on the key technology of boom correction is carried out,and a new technical scheme is proposed,aiming at realizing boom correction without disassembling the damaged parts.In order to verify the feasibility of this technical solution,3D modeling and finite element analysis simulation are carried out,and tested in factory.During the finite element simulation,the two ends of the undeformed boom are fixed and the lifting force is applied at the deformation.The actual test in the factory is also based on the above principle,through the hydraulic device to fix the boom,and then through the hydraulic jacking system to apply the lifting force at the deformation.Through the finite element simulation,the deformed boom will recover gradually when the lifting force reaches 40 t.In the factory test,when the lifting force reached 39.1t,the boom began to recover gradually,and the error was 0.0225,which verified the accuracy of the finite element method.Based on the above theories,the KL10-1F crane boom and WC19-1 platform boom were corrected,and the successful completion of these two correction works verified that the correction can be completed by hydraulic lifting device without disassembling the boom.These two successful cases not only provide effective support for the subsequent operation of the platform,but also provide important guidance and reference for other offshore drilling platforms to carry out similar crane maintenance in the future.
