The invention discloses an anti-torsion double positioning rope structure of a cable rope carrier of a cable rope hoisting system and a connecting method. The anti-torsion double positioning rope structure is characterized in that anti-torsion positioning ropes same in length are separately arranged on the left and right sides of the cable rope carrier and the connecting form of the positioning ropes and the cable rope carrier is converted from a conventional pressing plate form into a rope clip form. By implementing the anti-torsion double positioning rope structure, (1) the problem of easy torsion of the cable rope carrier using the single positioning rope is solved effectively under the circumference of guaranteeing consistence of length of the positioning ropes on the left and right sides of the cable rope carrier; (2) the double positioning ropes can avoid the problem that a partition plate of the cable rope carrier, a main cable, a pulling cable and a hoisting cable rub with eachother to be damaged as a result of torsion of the cable rope carrier effectively; (3) connected in form of the rope clips, a condition that the positioning ropes rub with corner angles of a side plate and a pressing plate of the cable rope carrier can be avoided effectively, so that that the service lives of the positioning ropes are guaranteed effectively; and (4) when construction cannot be carried continuously as a result of torsion, breakage and the like of the positioning ropes, the positioning ropes can be quickly replaced by detaching the rope clips.
