the steel strand (5) is continuously released after completely passing through the arc guide frame (1) until the end head of the steel strand (5) approaches the anchor position on the lifting jack, the steel strand clamping device (6) is removed, the steel strand (5) is placed into the jack one by one according to the corresponding relation, and the steel strand (5) is changed from horizontal arrangement into annular arrangement;
and placing the steel strands (4) into clamping grooves of grooved carrier rollers (4.3) of the end swinging frames (4) according to the corresponding relation, finally installing the middle guide plate (2) to ensure that the steel strands (5) are orderly arranged, opening the upper and lower clamping pieces of the jack to rapidly release the steel strands (5) to a lower construction platform, and thereby realizing side-by-side rope winding of the steel strands.
