摘　　要：大口径钢质管道内涂层补口是一个技术难点,该技术目前在国内还是空白。针对这一状况,研发了内防腐智能补口机设备。详细介绍了内补口机中除锈车和喷涂车的工作原理,论述了除锈机、喷涂机、行走机构扩展、电气控制等关于内补口机设计的内容,重点介绍了补口机的速度互换和补口工作时间、补口机自动返回、供电电源、补口定位等补口机的关键功能设计。对研制的内补口机的试验表明,该设备可初步满足钢质管道内防腐补口作业的要求,各项指标均达到国家标准的要求。At present, the internal joint coating is a difficult technical problem for the large diameter steel pipes. To solve the problem, the intelligent joint coating machine for pipeline internal anticorrosion is researched and developed. This paper introduces the working principle of the derusting car and spraying car of the internal joint coating machine, as well as the designs of the derusting car, spraying car, extending walking device and electric control, puts emphasis on the machine velocity exchange, working time for joint coating, machine automatic return, power supply, locating of joint coating, and so on. The test shows the machine can basically satisfy the requirement of internal joint coating of steel pipes, and various specifications reach the requirement of relevant national standards.
