Beschreibung
Zusammenfassung:	The utility model discloses a circumferential even-distribution synchronous-drive multi-shaft pipeline crawl device. The pipeline crawl device is composed of at least one driving unit, wherein the driving units are connected through universal joint connection shafts; each driving unit is composed of a motor, a power converting box, driving arms and driving wheels, the driving motor is connected with a transmission device in the power converting box, the transmission device in the power converting box is connected with the three driving arms which are evenly distributed at 120-degree intervals in the circumferential direction, and each driving arm is connected with one driving wheel; the transmission device in each power converting box comprises a worm and three worm gears, a worm shaft is connected with the three driving arms, and the worm and the worm gears are in meshing transmission. According to the circumferential even-distribution synchronous-drive multi-shaft pipeline crawl device, due to the fact that
