【摘要】：开发深海石油需要大量高技术含量的工程装备,水下法兰螺栓连接机具是一系列进行管道连接设备中的关键性设备,主要作用是实现深水法兰的螺栓连接,并保证连接的紧密性。本课题源自国家“863”计划“南海深水油气勘探开发关键技术及装备”子课题的分项目“深水海管水下回接技术及AUT检验设备国产化技术研究”。本论文的主要工作是完成水下法兰螺栓连接机具关键结构的设计,为下一步的深海工程样机提供技术支持和实践经验。论文对世界上主要使用的深海法兰连接装备进行归纳,介绍法兰螺栓连接机具的国内外发展现状。根据项目计划和法兰连接作业的技术要求提出了法兰螺栓连接机具的总体设计方案,并对关键部件的结构进行分析设计,建立了机具的三维结构模型,验证结构设计的可行性。水下法兰螺栓连接机具在结构上可以分为外框架、内基架、螺栓库、螺母库、拉伸器库等部分。对法兰螺栓连接机具关键结构进行分析研究,包括对库体沿管道轴线方向运动和法兰圆周方向转动的运动分析和运动机构的干涉检查。对接口箱、外框架和内基架主体板等关键零部件的强度校核和刚度分析,检验变形量能否控制在要求范围内,确保结构设计的可靠性。最后,在法兰螺栓连接机具机械结构设计的基础上,对液压系统和控制系统进行分析设计,确定了液压元件型号,设计了以可编程逻辑控制器作为枢纽控制的系统。
[Abstract]:Development of deep-sea oil requires a large number of high-tech engineering equipment. Underwater flange bolt connection machine is a series of pipeline connection equipment key equipment, the main role is to achieve deep-water flange bolt connection, This subject is derived from the national "863" plan "South China Sea oil and gas exploration and development key technology and equipment" sub-project "Deep water pipe underwater reconnection technology and AUT inspection equipment localization technology research" ". The main work of this paper is to complete the design of the key structure of underwater flange bolt connection machine. Provide technical support and practical experience for the next deep-sea engineering prototype. The paper summarizes the main deep-sea flange connection equipment used in the world. This paper introduces the development status of flange bolt connecting machine at home and abroad. According to the project plan and the technical requirements of flange connection operation, the overall design scheme of flange bolt connection machine is put forward, and the structure of key parts is analyzed and designed. The structure of underwater flange bolt connection can be divided into four parts: outer frame, inner base, bolt library, nut library, extender library and so on. The key structure of flange bolt connection machine is analyzed and studied, including the movement analysis of reservoir body along the axis of pipeline and the rotation of flange circumference, and the interference inspection of motion mechanism. The strength check and stiffness analysis of the key parts such as the outer frame and the main plate of the inner foundation are used to check whether the deformation can be controlled within the required range and to ensure the reliability of the structural design. Finally, on the basis of the mechanical structure design of flange bolt connection machine, the hydraulic system and control system are analyzed and designed, the type of hydraulic components is determined, and the system with programmable logic controller as the hub control is designed.
