流体驱动式管道裂纹检测机器人探头结构设计

Structure Design for Probe of Fluid-driven Pipeline Crack Detect Robot

管道机器人能有效的检测出油气管道存在的腐蚀缺陷,但对管道存在的裂纹缺陷无法有效的检出。设计了一种流体驱动式管道裂纹检测机器人的探头结构,可用于管道轴向裂纹的检测。论述了探头总体结构设计、弹簧支撑结构设计、支撑轮设计和检测探头壳设计。对设计的探头结构进行测试,结果表明:测试里程超过250 km,满足现场使用要求。该探头结构的设计为管道裂纹检测机器人的研制提供了参考。

The pipeline robot would detect the corrosion defects effectively which presented in the oil and gas pipeline,but the existed crack defects in the pipeline would not be effectively detected. A fluid-driven pipeline crack detect robot's probe structure was designed,which would be used to detect pipeline axial crack defects. The general probe structure,the spring supporting structure,the wheel structure and the probe structure were designed. The structure of the probe was tested,the results show that the structure of the probe running distance exceeded 250 km. The designed probe lay a foundation for the development of crack detection robot.
