Description

Special equipment for repairing inner wall of oil pipe Technical Field The utility model relates to the technical field of pipeline repair, in particular to special equipment for repairing the inner wall of an oil pipe. Background At present, various repair technologies exist in the industry for damages such as local corrosion, cracks and the like generated on the inner wall of an oil and gas pipeline. The traditional method is to excavate and replace the pipe, namely, the position of the damaged pipe is excavated by earth, the damaged pipe section is intercepted and replaced, the technology of the method is mature, and the repairing effect is reliable. Along with the technical progress, non-excavation repair technology gradually becomes mainstream, for example, a professional pipeline repair robot is adopted, and a plurality of working tools such as polishing, gluing and solidifying are carried into the pipeline to repair damaged points, so that large-area excavation can be avoided. However, the above-mentioned existing repair techniques, especially for a large number of common small-scale injuries, are generally associated with significant problems of high cost. The pipe-changing mode of excavation involves a large amount of earthwork, machinery and manpower, has long construction period, affects traffic and environment, has huge comprehensive cost, and is obviously uneconomical to treat a small corrosion point or crack. The highly-automated pipeline repairing robot is adopted, so that the excavation is avoided, but equipment such as a robot body, a ground control system, a power unit and the like is extremely expensive in cost, and later maintenance cost is not very good, and the operation of the robot is also required by personnel with professional skills. The use of such heavy, expensive equipment to treat daily, small-scale pipeline damage, as compared to "high-fire cannon mosquitoes", results in a significant mismatch in repair costs to actual demand, making many of the necessary preventive maintenance and early repair tasks difficult to perform economically. Therefore, we propose a special device for repairing the inner wall of the oil pipe.
