| description | The utility model provides a reciprocating telescopic pipeline crawler. The reciprocating telescopic pipeline crawler is characterized by comprising a retractor device, at least four supporting tightening devices, at least four groups of pulleys and at least four groups of contact blocks, wherein each supporting tightening device is connected with one contact block and one group of the pulleys, at least two supporting tightening devices are evenly distributed inside the circumference of an operating pipeline to form front supporting tightening devices, and the other two supporting tightening devices are evenly distributed inside the circumference of the operating pipeline to form back supporting tightening devices. The front supporting tightening devices are connected with the back supporting tightening devices through the retractor device on the central axis portion of the operating pipeline. Driving devices and springs are all arranged on the supporting tightening devices and the retractor device. The recip |
