Description
прорезей ниппел буровой штанги 12 к ловителю последний своим зевом 8 под действием пружины 7 захватывает прорезь 16. Ключ 4 начинает поворачиватьс вместе со штангой 12 до тех пор, пока не достигнет упора 2, в результате чего происходит стопорение ключа 4 вместе со штангой 12. Буровой станок, продолжа в то же врем враш,ать остальную колонну бурильных штанг, производит вывинчивание его из бурильной штангп 12, одновременно продолжа подачу ключа 4 вместе с траверсой 1 по направл ющим 3 в сторону неподвижной траверсы 5. В результате взаимодействи клиновых упоров 13 с пальцами 9 ключа 4 ловитель 6 выводитс из зацеплени с прорезью 16 штанги 12, отсоединенной от бурильной колонны .The slots of the nipple of the drill rod 12 to the safety device, the latter, with its shed 8 under the action of the spring 7, engages the slot 16. The key 4 begins to rotate with the rod 12 until it reaches the stop 2, resulting in the locking of the key 4 together with the rod 12. The drilling the machine, continuing at the same time vras, the rest of the string of drill rods, unscrews it from the drill rod 12, while continuing to feed the key 4 together with the crosshead 1 along the guide 3 towards the fixed crosshead 5. As a result V-ribs 13 with fingers 9 of key 4; the safety device 6 is disengaged from the slot 16 of the rod 12 disconnected from the drill string.
Описываемое устройство автоматизирует процесс развинчивани колонны бурильных штанг, что приводит к повышению экономичности проведени буровых работ.The described device automates the process of unscrewing the drill string, which leads to an increase in the efficiency of drilling operations.
