A labor-saving hauling rope positioning guide wheel comprises a roller, a pin shaft and two brackets, wherein the roller is movably mounted on the pin shaft; the pin shaft is mounted between the two brackets; and the upper ends as well as the lower ends of the two brackets are connected together through bolts. The labor-saving hauling rope positioning guide wheel is characterized in that one bracket comprises two parts that are hinged with each other; the upper end of the hinged two parts is retractably connected with the bolts; two conducting wire clamp blocks between the two brackets are movably sleeved on the bolt at the upper ends of the two brackets; the two conducting wire clamp blocks are provided with rabbets that are opposite to each other; and a fastening bolt is connected between the two conducting wire clamp blocks. By adopting the technical scheme, the labor-saving hauling rope positioning guide wheel has the advantages of simple structure and convenience in use, can prevent oscillations caused by the sagging of a hauling rope, and can also prevent a conducting wire from being damaged and improve the operational safety; and through the hauling rope, the labor intensity can be remarkably reduced, the working time is shortened, and the work efficiency is improved.
