[0060] The motor 22 is started, driving the anti-skid wheel 23 to move along the inner wall of the pipeline, thereby dragging the cable to be laid to move along the pipeline.

[0061] When the device moves to a turning point, the pressure sensor 21 transmits a pressure signal to the controller, and the controller adjusts the extension and retraction of the electric-controlled telescopic rod 16 and the electric telescopic rod 4 according to the received pressure feedback, so that the spherical shell 9 can pass through the turning point smoothly.
