An auxiliary drawing head of a power cable threading apparatus comprises a first cleaning disc (1), a second cleaning disc (2), a plurality of rollers (8) and a connector. The rollers are disposed on the first cleaning disc and the second cleaning disc; the first cleaning disc and the second cleaning disc are in a disc shape and provided with connector penetrating holes and a plurality of screw rod holes located on peripheral disc surfaces of the connector penetrating holes; screw rods (3) penetrate through the screw rod holes; the screw rods on two sides of the first cleaning disc and the second cleaning disc are in threaded connection with nuts (4) so that the first cleaning disc and the second cleaning disc are connected into a whole; the diameter of the first cleaning disc and the diameter of the second cleaning disc are larger than that of a cable; the rollers protrude out of the peripheries of the first cleaning disc and the second cleaning disc. The auxiliary drawing head can effectively remove sundries in a pipeline, prevent sundries from damaging the surface of the cable, and improve construction quality and efficiency. |
