【摘要】：自升式钻井平台关键部件建造工艺技术的研究形式非常复杂,国内外升降、锁紧机构主要由国外设计公司垄断,但这些设计方案的测量精度和自动化程度都存在不足,不能适应升降、锁紧机构应用技术迅猛发展的需要。因此,本文的研究,对进一步提升我国高端海洋工程装备关键配套设备国产化率具有重大的工程实用意义。基于国内自升式钻井平台研制过程中关键设备受制于人的现状,现开展自升式钻井平台关键部件建造工艺技术研究工作,力求在关键部件升降及锁紧机构研制过程中,开展技术突破,实现关键装备自主研制。首先,研究分析了升降、锁紧结构,基于渤海装备CP300自升式钻井平台研究对象,确定了升降、锁紧装置的选型。接着研究设计了升降系统,并对每个桩腿在不同载荷工况下、任意风负荷工况下、自身重量可变负荷和任意方向风负荷共同作用下等3种工况进行了受力分析。使用ANSYS软件对齿轮齿条升降系统进行了有限元分析,得到爬升齿轮的最大应力值小于屈服极限,满足设计要求。研究设计了锁紧机构在不同工况下,锁紧齿条的负荷分配、受力分析,得出锁紧装置的结构数据,满足设计要求。通过自升式钻井平台关键部件建造工艺技术的研究,完成了升降、锁紧机构设计,以实现渤海装备自主应用的目标。
[Abstract]:The research form of construction technology for key components of jack-up drilling platform is very complex, the lifting and lifting at home and abroad, the locking mechanism is mainly monopolized by foreign design companies, but the measuring accuracy and automation degree of these design schemes are insufficient.Can not adapt to lifting, locking mechanism application technology rapid development needs.Therefore, the research in this paper is of great practical significance to further improve the localization rate of key supporting equipment of high-end marine engineering equipment in China.Based on the fact that the key equipment is controlled by people in the development of domestic jack-up drilling platform, the research work on the construction technology of the key components of the jack-up drilling platform is carried out in order to make every effort in the process of the development of the lifting and locking mechanism of the key components.Carry out technical breakthrough and realize independent development of key equipment.Firstly, the lifting and locking structure is analyzed. Based on the research object of CP300 jack-up drilling platform of Bohai Sea equipment, the type selection of lifting and locking device is determined.Then, the lifting system is designed and analyzed under different load conditions, arbitrary wind load, variable weight load and wind load in any direction.The finite element analysis of gear rack lifting system is carried out by using ANSYS software. The maximum stress value of climbing gear is less than the yield limit, which meets the design requirements.The load distribution and force analysis of the locking rack under different working conditions are studied and designed. The structural data of the locking device are obtained to meet the design requirements.Through the research on the construction technology of the key components of the jack-up drilling platform, the design of lifting and locking mechanism is completed to realize the goal of independent application of Bohai Sea equipment.
