管内高压智能封堵机器人

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。

The In-tube Pressurized Intelligent Plugging Robot

To meet the domestic needs of fast maintenance of pipeline,research on the plugging technology of pipeline 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 removal test.The tests have proved that the robot can achieve multiple plugging and plug removal operations in a section of pipeline.This remarkably shortens the pipeline shutdown time.The operation is simple and the plugging performance is desirable.The robot can plug as high as 20 MPa pressure with no leakage.The successful development of the robot serves as a supplementation for domestic pipeline maintenance technology.
