摘　　要：为解决管道工程现场防腐补口单功能设备简单组合的机组构成庞大、人员配置较多、施工组织复杂及施工成本难以降低等突出问题,结合热收缩带防腐补口施工工序特点,通过相邻工序所需功能的优化整合,研发了以具有无遗漏除锈与全覆盖加热功能的除锈&中频一体式设备,以及具有内外协同加热功能的中频&红外一体式设备为核心的集成化防腐补口装备,制定了配套的补口工艺。模拟试验与工程测试结果表明,集成化防腐补口装备与工艺实现了管道待补口区域表面处理与预热的工序整合及同步作业、底漆加热与热收缩带收缩熔胶的工序整合及协同作业,以及机械化防腐补口施工方式由四工位向三工位的重大转变,在施工方式、设备构成、人员配置、施工效率、机械化程度和施工成本等方面优势明显。且自主开发的数据采集与无线传输功能模块与控制系统的嵌入融合,实现了防腐补口关键施工数据的实时采集、存储及与数据终端的无线传输,可为智能管道数字化移交及完整性管理提供数据支撑。针对管道工程连续口、连头口及返修口等不同类型焊口的防腐补口,提出了集成化防腐补口装备的优化组合建议,可为工程单位优化配置防腐补口机组提供参考依据。Generally,when anti-corrosion joint coating operation is demanded in pipeline construction site,some single-function anti-corrosion joint coating units are combined simply.However,they have some problems such as a giant unit composition,large staffing,complex construction organization and high construction cost.In order to solve these problems,the functions required in continuous processes were optimized and integrated considering the features of anticorrosion and joint coating procedure of heat shrinkable tape,and an integrated joint coating equipment was developed which is mainly composed of a rust removal-intermediate frequency integrated equipment with function of fully covered rust removal and heating and an intermediate frequency-infrared integrated equipment with function of internal and external collaborative heating.Meanwhile,supporting joint coating process was designed.The simulation and test results show that,the integrated anti-corrosion joint coating equipment and process realized the integration and synchronization of surface treatment and preheating in the pipeline area to be patched,the integration and cooperation of primer heating and shrinking and melting of heat shrinkable tape,and the significant transformation of mechanized anti-corrosion joint coating construction mode from four stations to three stations,with obvious advantages in construction mode,equipment composition,staffing,efficiency,mechanization,construction cost and so on.Moreover,the independently developed data acquisition and wireless transmission function module was embedded and integrated with the control system,which realizes the real-time acquisition and storage of key data of anticorrosion patching construction and wireless transmission of data terminals.It could provide data support for digital delivery and integrity management of intelligent pipelines.For different types of welded junctions for anticorrosion joint coating in pipelines,such as continuous junctions,joint junctions and repair junctions,suggestions on optima
