大庆石油学院本科生毕业设计（论文） 摘要 本课题 研究内容属于 修井井口作业自动化 系统中动力卡瓦的结构设计 。 课题主要目的就是用动力卡瓦实现对管柱的提升，卡紧及悬挂。 设计中， 利用 液压缸施加作用力 ， 经连杆机构的传递， 推动卡瓦楔体沿卡瓦座体内锥面 上下运动 ， 上行时，卡瓦牙板内径不断增大，使管柱通过；下行时，卡瓦牙板收拢， 内径变小，从而 卡紧管柱。 对于管柱的卡紧与悬挂，在井口作业中是一个重要的组成部分。 动力卡瓦是卡住并悬挂下井的油管、钻杆、钻铤等管柱的必要工具 ， 但是每一种结 构的卡瓦都有它的优点和缺点。本课题主要是对动力卡瓦进行结构设计以及 对动力卡瓦承载零件 的受力分析和强度校核 。 关键词 ：卡瓦；结构；强度 ；悬挂能力 nts大庆石油学院本科生毕业设计（论文） Abstract The content of this research are workover operations wellhead automation system dynamics of the structural design of Slips. The main purpose of the subject is to use power to achieve string slips upgrading cards and hanging tight. Design, use of force to exert hydraulic cylinder, the transmission linkage, and promote slips kava wedge blocks along the upper and lower body movement cone, on the line, slips increasing diameter of dental lamina, so that through the string; downlink, the slips drawing in dental lamina, smaller diameter, thereby card string tight. For the string tight and the suspension of the card, operating in well-head is an important component. Driving force for slips is jammed and flying to go down the pipeline, drill pipe, drill collar, such as an essential tool string, but the structure of each slip has its own advantages and disadvantages. The main issue is the driving force for the structural design of Slips and Slips bearing parts of the power and strength check of force
