管内高压智能封堵机器人

摘要

为满足国内管道快速维修的需要,开展了管道智能封堵技术研究.在介绍管内智能封堵机器人的封堵作业流程后,描述了封堵机器人的结构组成,包括双向清管式封堵单元、远程控制系统和地面控制中心,给出了主要技术参数.随后简要介绍和分析了封堵机器人的性能试验情况,包括通过性能试验、双向通信和压力试验以及解封试验.试验证明封堵机器人可在一段管道内实现多次封堵和解堵作业,大大缩短管道停输时间,且操作简单,封堵性能良好,能够封堵20MPa的高压,无渗漏.该智能封堵机器人的研制成功为国内管道维抢修技术提供了补充.%To meet the domestic needs of fast maintenance ot pipeline,research on the plugging technology ofpipeline was conducted.The paper first introduces the plugging process of in-tube intelligent plugging robot,describes the structural composition of the robot,including two-way pigging plugging unit,remote control system and ground control center,and offers the main technological parameters.Then,it briefly introduces and analyzes the performance test of the robot,including passage capacity test,two-way communication,pressure test and plug re-moval test.The tests have proved that the robot can achieve multiple plugging and plug removal operations in a sec-tion of pipeline.This remarkably shortens the pipeline shutdown time.The operation is simple and the plugging per-formance is desirable.The robot can plug as high as 20 MPa pressure with no leakage.The successful developmentof the robot serves as a supplementation for domestic pipeline maintenance technology.
