设计简介
摘要：管道运输是油气运输中最主要、最快捷、经济、可靠的方式，可用于输送水、原油、天然气、成品油等，具有输量大、距离长、安全性高、成本低等优点，在各国发展迅速。管道运输业的主体是管道，管道工程的核心工作是管口的焊接。因此研究高效率、性能可靠的管道全位置自动焊接机具有十分重要的意义。
为解决管道建设野外作业的自动化焊接的难题，研制了一种导轨式管道焊接机器人，其关键技术包括：研制新型的行走机构、焊枪摆动机构、及机器人轨道、焊枪机械手。介绍了导轨式焊接机结构的设计和焊接机控制，着重对其结构特点、动作原理、设计要点进行设计分析和说明。现场应用表明，该机器人能沿导轨平稳、可靠的行走，进行管道外圆全位置焊接，其操作简便，成本低，适合我国现场施工作业及工人的技术水平，既保证了焊接质量，又提高了劳动效率。

Abstract: Pipeline transportation is the most important, quickest, economical and reliable method in petroleum transportation. It can transport water, crude oil, natural gas, oil product etc. It has a number of advantages: high transmission volumes, long distance, safety and cost-effectiveness, which is rapid developed in all the world. The subject of pipeline transportation is pipeline; the core of pipeline project is nozzle welding. So, it has very important significance to develop high efficient and reliable performance pipeline all-position automatic welding machine.
An orbit pipeline welding robot has been developed to solve the problem of automatic welding during pipeline construction in the fields. Its key techniques consist of developing a new type of travel unit, welding torch as cillating unit, robot orbit and intelligent control system etc. The development work of the orbit pipeline welding robot mechanic system is introduced in the paper. The main illustration is about the system's structure，action principle，key points of design and machining technies and verifying calculation for selecting reduction gearbox with the wire feeder motor and the diameter of the wire-feed wheel. The application in fieldwork shows that the robot can trave1 along the orbit stably and reliably and carry through all-position welding. The welding is easy with low cost that is fit for fieldwork and worker in our country，guarantees the welding quality and improve working efficiency.
