灵活提引环的构造如图所示。是在普通提引环上将心軸延长再增加一盘滾珠和突出卡槽。滾珠能提高提引环的灵活性,借以消除鋼繩扭力。为了防止跑管的冲击现象,特增长心軸以起緩冲作用。卡槽是防止跑管的最好方法。
The structure of the flexible pick-up ring is shown in the figure. The mandrel is extended on a common pick-up ring by adding a ball of ball and protruding the card slot. The ball can increase the flexibility of the puller ring to eliminate the twisting force of the steel rope. In order to prevent the running tube from impacting, the mandrel is specially grown to act as a buffer. The card slot is the best way to prevent running pipes.
