HANDLING OF TUBE SECTIONS IN A RIG FOR SUBSOIL DRILLING |
摘要 |
A drive unit (1) for a subsoil drilling rig comprises a drive unit (5), an engagement unit (12) for releasably engaging a tube section (13) extending therefrom in a drilling direction and a gripper (15) movable relative to the engagement unit (12) between a first position for gripping a tube engaged by the engagement unit (12) and a second position for gripping a tube section (13) in a transfer position. Supplied tube sections (13) can be handled reliably and movements of supplied tube sections (13) can be controlled accurately. Co- ordination of positions and movements between the supplied tube sections (13) and the drive unit (1) is simplified. A drilling rig incorporating such a drive unit (1) and a method employing such a drive unit (1) are described as well. |
