Description
(54) МЕХАНИЗМ УДЕРЖАНИЯ БУРОВОЙ КОЛОННЫ(54) MECHANISM FOR CONTAINING DRILL COLUMN
захвата механизма с удерживаемой буровой колонны будет различна. Поэтому, после того, как элеватор прин л вес буровой колонны и захватного механизма, подачей давлени в бесштоковую полость расклинивающих гидроцилиндров 7, без дополнительной нагрузки на талевую систему, освобождают буровую колонну от захвата плашками.The gripping mechanism with the retained drill string will be different. Therefore, after the elevator has received the weight of the drill string and the gripping mechanism, by applying pressure to the rodless cavity of the wedging hydraulic cylinders 7, without additional load on the pulley system, the drill string is released from the dies.
