As shown in fig. 1, 2 and 4, a cable laying traction device for electric power construction comprises a traction mechanism and a laying auxiliary mechanism, wherein the laying auxiliary mechanism comprises a fixed frame and a pulley 4, the fixed frame comprises a connecting piece 2 and two inverted U-shaped fixing pieces 1, two ends of the connecting piece 2 are respectively arranged at the bottom of one side of the two fixing pieces 1, and the pulley 4 is rotatably arranged between the two fixing pieces 1; the fixing pieces 1 are respectively provided with a fastening piece.

During the use, lay a plurality of complementary unit at a certain distance intervals equipartition on crane span structure 8, specifically, erect the mounting 1 of falling the U type on the both sides wall of crane span structure 8 to through the fastener with mounting 1 with the inseparable butt of crane span structure 8. The traction mechanism is erected on the pulley 4, and after the tail end of the traction rope is tied with one end of the cable, the traction mechanism can be started to pull and lay the cable through the traction rope. The pulleys 4 uniformly distributed at intervals play a role in sliding support of the cable, so that the friction force of the cable in the traction process is greatly reduced, and the cable is conveniently pulled. In this embodiment, the traction mechanism is a winch, and the surface of the pulley 4 is arc-shaped, so as to limit the cable to a certain extent, i.e., prevent the cable from slipping off the pulley 4 to a certain extent. The fastener is bolt 7 and the bolt hole of setting on mounting 1, twists bolt 7, and bolt 7 and fastener are supported through the screw action and are pressed on crane span structure 8, avoid fastener and crane span structure 8 to take place relative movement.
