The invention relates to the technical field of cable laying, and discloses a cable laying auxiliary device for detecting whether the cable
skin is intact. The device comprises a cable
skin detectiondevice main body, supporting frames are fixedly installed on the inner walls of the left and right sides of a U-shaped block, motors are fixedly installed at the tops of the supporting frames, and brushes are fixedly installed on the right sides of the motors. A sliding groove is formed in the bottom of the U-shaped block, a sliding block is slidably connected into the sliding groove, and a single-pole
magnet is fixedly installed at the top of the sliding block. The motor drives the
brush to rotate and contact and rub with the cable passing through the U-shaped block, if the surface of the cable is not damaged, the cable does not generate electrons due to the effect of the insulating leather sheath on the surface of the cable, and when the surface of the cable is damaged, the
brush is in direct contact with
copper wires in the cable, so that the surfaces of the
copper wires are charged; the single-pole
magnet at the bottom is used for detecting the passing cable, and the effect of detecting whether the
skin of the cable is intact or not is achieved.
