[0002] In modern cities, cables (including optical cables and electrical cables) are generally laid in underground cable ducts. At regular intervals, there is a maintenance well for laying and inspecting cables. When laying cables, the cables are sent into the cable duct from the maintenance well at one end of the cable duct, and then dragged to the maintenance well at the other end of the same cable duct using a dragging device.

[0003] Patent document CN210985463U discloses a cable laying auxiliary device, including a horizontal frame for being placed across the opening of a maintenance well and a vertical frame for extending into the maintenance well. The vertical frame is fitted into a rectangular sleeve fixed to the horizontal frame. Bolts for fixing the vertical frame are screwed onto the side wall of the rectangular sleeve. Two first guide wheels located on the same horizontal plane are installed on the horizontal frame, and two second guide wheels located on the same vertical plane are installed at the bottom of the vertical frame. U-shaped grooves are provided on the outer center of the first guide wheels and the outer center of the second guide wheels. The beneficial effects of this utility model are: the cable crosses over the first guide wheels, avoiding friction between the cable and the well opening and thus preventing damage to the cable surface; the cable crosses over the second guide wheels, and the cable crossing over the second guide wheels is aligned with the center of the cable tube, avoiding friction between the cable and the cable tube opening and thus preventing damage to the cable surface; and it can reduce the resistance of the cable when dragging.
