[0002] In the process of existing pipeline maintenance, rerouting, adding branches, etc., in order not to affect the use of users on the line, the pipeline non-stop construction method is often used. Pipeline non-stop construction requires welding plugging pipe fittings on the pipeline, and then installing gate valves, hole opening machines, chip cleaners, pluggers, lower plugs and other equipment on the pipe fittings to complete the opening, cleaning, and plugging of the pipeline, and then complete the maintenance, rerouting, and adding branches of the pipeline. After these works are completed, the plugger is removed, and the plug is installed in the plugging pipe fitting to complete the plugging of the opening, and finally the blind plate is covered and backfilled. After the pipeline is opened, a large amount of iron filings will fall into the pipe, which affects the subsequent construction work and needs to be removed before plugging. The existing technology requires multiple disassembly and assembly of equipment for cleaning, manual use of wire brushes to clean the iron filings, and then the use of magnet blocks to absorb the iron filings and bring the iron filings out of the pipeline. Manual removal of the iron filings on the magnet is time-consuming and labor-intensive. The invention patent with publication number CN110883028A discloses a device for cleaning iron chips inside a gas pipeline, comprising a hollow sphere located inside the gas pipeline and an outer ring body surrounding the outer wall of the gas pipeline; the outer wall of the hollow sphere is provided with a plurality of retractable balls along its circumference, the outer wall of the hollow sphere is detachably connected with a brush strip, a first magnet is provided inside the hollow sphere, and an iron chip adsorption cavity is provided between the first magnet and the inner wall of the hollow sphere; the outer ring body comprises a first arc plate and a second arc plate hinged to the first arc plate, rollers are arranged at intervals on the inner wall of the first arc plate and the inner wall of the second arc plate, and a second magnet magnetically connected to the first magnet is arranged between any two rollers; a support rod is also included, and electric telescopic rods connecting the first arc plate and the second arc plate are respectively arranged on both sides of the top end of the support rod. The device can magnetically adsorb the iron chips remaining in the gas pipeline and remove them to the outside of the pipeline, but the number of iron chips adsorbed by the magnet block of the device is limited, and it is necessary to disassemble and assemble the equipment many times for cleaning, which is time-consuming and labor-intensive.
