    摘要: The invention relates to a drilling apparatus for producing a cased bore with a first drill drive for driving a drill rod in a rotating manner, at the lower end of which a drilling tool for removing ground material is arranged, a mast, along which the first drill drive is movable with a sledge, and a second drive, with which a support tube for the bore can be introduced into the ground. According to the invention a computer unit is provided, in which a current drilling depth of the drilling tool and a depth of introduction of the support tube are indicated. Furthermore, a monitor is provided, on which the current drilling depth in relation to the depth of introduction of the support tube can be displayed by the computer unit. The invention further relates to a method for operating such a drilling apparatus.

    摘要: Apparatus and methods are for coupling a drive unit to a tool adapter. A drive unit includes a drive stem; a plurality of sliding coupling members; a retainer; a torque profile; a plurality of drive stem ports; a coupling collar; coupling recesses; a plurality of transmission units; and/or first portions of a hydraulic coupling unit. A tool adapter includes a tool stem; a tool stem sleeve; coupling recesses; a torque profile; a plurality of sliding coupling members; and/or second portions of the hydraulic coupling unit. A method of coupling a drive unit to a tool adapter includes positioning the tool adapter below the drive unit; stabbing a drive stem into an interior of a tool stem sleeve; coupling torque between the drive unit and the tool adapter; and coupling load between the drive unit and the tool adapter by engaging a plurality of sliding coupling members.

    摘要: The invention relates to a drilling apparatus and a method for introducing a drilling element into the soil. The drilling element is rotatably and slidably supported on a mast, with a torque being applied through a rotary drive located on the mast. In order to support the torque an additional turning device is fixed to the mast, which can be engaged with the driven drilling element.

    摘要: The invention discloses an induced drilling method for inertial constraint implicated motion, which is characterized by comprising a motion step of separating weight on bit and torque. The induced drilling method of inertial constraint implicating motion comprises the following steps: step 1, model selection of induced drilling; step 2, potential energy storage of induced drilling, wherein step 2 includes: I, uniform cutting induced drilling under a steady condition; II, distribution of induced drilling shock wave propagation under a transient condition; III, potential energy release of torsion spring in induced drilling under the transient condition; IV, constrained buffer for induced drilling under transient conditions; and V, potential energy compensation for induced drilling under transient conditions. The invention also discloses an inertia constraint induced drilling device accompanying the PDC bit.
