6. A working method of a pipeline conveying device for slitting large-caliber thick-wall pipes is characterized by comprising the following steps:
the method comprises the following steps: conveying the large-caliber thick-wall pipe into a second conveying channel (200) through a guide shell (401), wherein three conveying tracks on three limiting shells (305) are in contact with the outer wall of the large-caliber thick-wall pipe, and the three conveying tracks convey the large-caliber thick-wall pipe;
step two: when the position to be cut on the large-caliber thick-wall pipe passes through the guide shell (401), the second conveying channel (200) drives the large-caliber thick-wall pipe to rotate, a precutting cutter head (403) opens precutting grooves on the outer surface of the large-caliber thick-wall pipe during rotation, the conveying crawler conveys the large-caliber thick-wall pipe to a position between the first conveying channel (100) and the second conveying channel (200), then the position on the large-caliber thick-wall pipe where the precutting grooves are opened is cut to obtain two large-caliber thick-wall pipes, and a pump (703) extracts waste chips generated in the cutting process through an ash collecting cover (702) in the cutting process;
step three: the first conveying channel (100) and the second conveying channel (200) move in the opposite direction, a piston rod of a jacking cylinder (607) pushes a lifting plate (606) to ascend, then two water outlet discs (610) ascend to a position between the first conveying channel (100) and the second conveying channel (200), then the first conveying channel (100) and the second conveying channel (200) move in the opposite direction, the two water outlet discs (610) respectively enter two large-caliber thick-wall pipe cutting positions, a water pump (609) pumps water through a telescopic hose (605) and a flow dividing pipe (608), and the water is sprayed to the inner wall of the large-caliber thick-wall pipe through a through hole in the water outlet discs (610), so that the large-caliber thick-wall pipe is cleaned.
