The invention discloses a direct pass-through stringing pulley of a primary guide rope. The direct pass-through stringing pulley of the primary guide rope is characterized in that the stringing pulleycomprises a frame body, a pulley group, a center bearing assembly, a link plate, a drone direct pass frame and a primary guide rope guide mechanism; the pulley ground and the frame body are fixed bythe center bearing assembly; the upper end of the drone direct pass frame is connected with the link plate while the lower end is fixed with the upper portion of the frame body; the primary guide ropeguide mechanism comprises a upper centered guide rod group and a lower centered guide rod group; the upper centered guide rod group comprises a left upper guide rod and a right upper guide rod whichare both in inclined setting toward a crossing; the lower centered guide rod group comprises a left lower guide rod and a right lower guide rod; the upper ends of the left lower guide rod and the right lower guide rod are respectively hinged with the left end and right end of the crossing. The direct pass-through stringing pulley of the primary guide rope has the advantages of saving trouble, timeand energy with cooperation operation of high altitude personnel no needed, reducing line construction time, improving line construction efficiency and enhancing social benefits of construction.
