摘 要 在油田修井作业过程中，依据新型修井作业油管钳系统的功能要求，提出新型修井作业油管钳主钳的设计方案及工作机构的改进设计。采用主钳、背钳安装在移动机构上，移动机构安装在井口上，主钳位于背钳之上，通过导杆总成连接，钳体沿移动机构导轨实现进给运动。采用坡板凸轮夹紧机构，钳头在正反方向连续卡紧管径为Φ60~89mm的管柱，卡紧性能好，结构紧凑。为了提高修井效率，减轻修井工人的劳动强度，使工人尽量远离恶劣的工作环境，将目前的手动大钳改进为自动作业修井钳。主钳在对缺口和换挡上实现了自动化控制，设计方案结构简单、紧凑，性能可靠。作为石油修井作业过程中的重要设备，实现系统自动化控制是未来发展方向。 关键词：修井作业；油管钳；主钳；改进设计 Abstract In the oil field processes of workover, the article have put forward the system design proposals and then improvement design the working mechanism of new tubing tongs, which are all based on the functional requirements of new tubing tong system. The use of the main tong and back tong are installed on the mobile body, the mobile body are installed on the well head, the main tong located on the back tong and connected by the guide rod assembly.The tubing tong along the rails of the mobile body to achieve the feed movement. The use of cam plate clamp body, the head in the pro and con direction continual clamp tight 60 ~ 89mm diameter of the string, it has good chucking character and compact in the structure. In order to improve the efficiency of workover, reducing labor intensity of workers and staying away from poor working conditions, the present manual tong improves for the automatic tong of workover. The main tong realize automate control in aline the gaps and shifte gears, the design proposal simple and compact in the structure, and reliable in the function. As the critical equipment of oil workover, the realization of automatic control system is the future direction of the development. Key words: workover; tubing tong; main tong; improvement design 目 录 第1章 概述...........................................................1 1.1修井作业系统之自动作业钳概述............................... 1 1.2 国内外研究现状............................................ 3 1.3本文研究内容............................................... 6 第2章 修井作业自动化主钳方案确定.....................................7 2.1主钳方案的确定............................................. 7 2.2 主
