The utility model discloses a quick laying apparatus of well cable comprises a plurality of articulated of looks in proper order assembly pulleys, its characterized in that: the assembly pulley comprises bottom plate, both sides board, shaft and pulley, and the both sides of bottom plate are fixed in to both sides flatly capable, and on the both sides board was fixed in at the both ends of shaft,the pulley rotationally set up in the wheel epaxially, the both sides of curb plate lower extreme all are provided with the link bolt, and it is articulated mutually that two adjacent assembly pulleyspass through the link bolt, be fixed with the gag lever post on the surface of the both sides board of the assembly pulley of one end. The utility model discloses a quick laying apparatus of well cable, but rotation between the assembly pulley can form the radian with cable matched with, can avoid the cable to take place great bending, through the pulley to the bearing and rolling of cable, can avoid cable and well mouth border to take place the friction, realized the guard action to the cable, still improved the efficiency of laying of cable simultaneously.
