摘　　要：针对传统内检测器的技术缺陷及中俄东线天然气管道工程的实际需求,研制了一种适用于大口径管道投产前测径的新型高密度聚氨酯内检测器。安装在高密度聚氨酯泡沫主体的智能测径装置不但能够发现管道内径变化、记录变形位置,而且能够准确识别管道环焊缝数量,结合管道施工记录对环焊缝信息进行验证。论述了该检测器的工作原理、结构组成及电子系统的设计与实现,将其应用于中俄东线天然气管道工程的现场检测,结果表明:与传统皮碗式钢骨架智能测径器相比,该检测器所需运行推力更小,可支持的运行速度更高,结构更加鲁棒,维护简单,在保证检测精度与检出率的同时,可大幅降低使用成本,对于大口径管道几何变形检测具有重要的工程意义。(图7,参28)In order to solve the technical defects of the conventional inner detector and to meet the actual demands of China-Russia Eastern Gas Pipeline Project,a new type of high density polyurethane inner diameter detector for large diameter pipelines before service was developed.The intelligent diameter measuring device mounted on the main body of high density polyurethane foam can not only find the change of the inner diameter of the pipeline and record the deformation position,but also accurately identify the number of girth welds of the pipeline,so as to verify the girth weld information in combination with the pipeline construction records.The working principle,structural composition and design and implementation of the electronic system of the detector were discussed.The detector has been applied to the site inspection of China-Russia Eastern Gas Pipeline Project.The results show that,compared with the conventional cup-shaped steel skeleton intelligent diameter measuring detector,the required operating thrust of the detector is smaller,the allowable operating speed is higher,the structure is more robust,and the maintenance is simple.While ensuring the detection accuracy and detection rate,the detector brings dramatic decline in use cost and important engineering significance for the geometric deformation detection of large diameter pipelines.(7 Figures,28 References)
