摘要
管道在能源的运输方面具有重要的作用,其安全、合理、稳定的运行具有重要的意义。以DN250~350 mm的油气管道为主要应用场景,设计了一种以丝杆螺母变径机构达到自适应目的的履带式管道巡检修复机器人。该履带式管道巡检修复机器人分为驱动单元、检测单元、连接单元和隔离修复单元。通过几何分析研究管道几何约束对弯管通过性的影响可知,当该机器人组成单元的长度小于452.88 mm时,从几何约束角度分析可以通过弯管;运用坐标转化法对机器人运行过程进行了运动状态分析,研究该管道机器人的运动特性,得到该机器人的速度方程。由分析可知,履带式机器人采用3履带差速特性的方式通过弯管时运动更加平稳。采用仿真分析的方式,验证了其对弯曲管道形态的通过性。该研究可为油气管道的稳定巡检、应急安防与处理处置提供参考。
The pipeline plays an important role in the transportation of energy,and its safe,reasonable and stable operation is of great significance.This study takes DN250-350 mm oil and gas pipelines as the main application scenario,and plans to design a crawler-type pipeline inspection and repair robots that use a screw nut reducing mechanism to achieve diameter reduction to achieve self-adaptive purposes.The crawler-type pipeline inspection and repair robot can be divided into a drive unit,a detection unit,a connection unit and an isolation repair unit.When the length of the constituent unit of the robot is less than 452.88 mm,it can pass through the elbow from the analysis of geometric constraints.The speed equation of the robot can be obtained by analyzing the motion state of the robot during the running process by the coordinate transformation method.The crawler robot moves more smoothly when passing through the bend with the 3-track differential characteristic.By means of simulation analysis and experimental verification,the passing ability of the elbow is verified.The research on the passing ability of the crawler-type pipeline inspection and repair robot can provide some references for the stable inspection,emergency security and treatment of oil and gas pipelines.
