双基站空间定位与测量系统在主管道安装中的应用
Application of dual base station spatial positioning and measurement system in installation of main pipelines
摘要
Abstract
In response to the issues of traditional monitoring methods for welding deformation and trends of main pipelines,such as dial gauges and rulers,which require high levels of personnel skills,involve large amount of data calculation,and have delays in feedback,the research has primarily focused on the application of dual-base station spatial positioning and measurement systems for dynamic monitoring during the installation process of main pipelines.Based on non-contact and array-type measurement characteristics,this system can achieve one-time measurement of multiple measurement points within the field of view through multiple cameras to instantly obtain a large amount of data,and exhibits a technical advantage of high measurement efficiency.Through the implementation of technological processes including simulated positioning of pipe orifices at various main equipment ends,on-site layout and calibration of the measurement system,selection of monitoring benchmarks,and monitoring of the assembly and welding process,the system achieved full-process monitoring of the welding of the main pipeline in a nuclear power project,and can effectively grasp the changes in pipeline displacement.Based on cumulative analysis of the monitoring data of each pipe orifice,the cumulative shrinkage was found to be in the range of 7.43～8.73 mm,satisfying the pre-reserved installation adjustment and control allowance of 7～9 mm.This verifies that the system can provide precise data support during the installation and assembly process of the main pipeline,demonstrating its certain application value in quality control and work efficiency improvement.关键词
