深水钻井隔水管监测系统夹装装置开发及应用

随着我国深水钻井装备队伍的不断壮大,其配套的安全保障技术需求日益突出。深水钻井隔水管是水下井口与钻井船的纽带,保障其作业安全意义重大,国际公认的措施是在钻井作业期间对隔水管开展实时监测。"十二五"期间,我国研制了一套隔水管监测系统工程样机。为该样机设计了一种绑带式夹装装置,用于将监测设备安装在隔水管上。通过在"兴旺号"钻井船上实际应用,验证了监测设备夹装装置的可靠性和对监测作业的适应性。

电测量仪表自动检定装置的设计

为提高电测量仪表的标定以及检定工作的自动化程度以及效率,针对各典型仪表,设计了专用的快速夹装装置,基于C#以及openCV,设计了数码管识别代码以及标准器控制代码,并在此基础上,设计了人机交互界面,实现了对原始记录的自动生成。结果表明,利用电测量仪表自动检定装置,能在1分钟内完成仪表的夹装、测量以及原始记录的生成,相比之前10~30分钟的操作周期,此装置能够更好得适应大规模生产型企业对仪表的出厂检定工作。

Entirety transformation mechanism and topological-type synthesis for heavy-duty gripping devices

Force closure and stability problems exist in heavy gripping devices.Based on a typical gripping device for forging operations, the workpiece and the gripping device are innovatively considered as a single mechanism in this paper,and its global topological configuration is obtained.The changing element method is used to establish the optimized topology geometry of the gripping device by decreasing the degrees of freedom of the gripping mechanism and improving the force closure performance. Therefore,a new idea for the innovative design of heavy-duty forging gripping devices is provided.As the effect of revolute joint friction on loading capacity of the gripping device cannot be ignored,a unified mechanical equation including friction in terms of the topological adjacency matrix is established to analyze the force closure performance and calculate the loading capacity.The conclusions are provided by experiments.
