Abstract
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.
Claims14
Drilling apparatus for introducing a drilling element into the soil, the drilling apparatus comprising:
- a mast;
- a rotary drive, which is supported on the mast for introducing the drilling element arranged rotatably and slidably on the mast;
- at least one operating cylinder;
- and
- a turning device having a collet that can be turned by means of the at least one operating cylinder;
- a supporting bearing;
- wherein the turning device is supported on the mast by the supporting bearing through which the collet can be pivoted in the drilling direction and can be engaged with the drilling element driven by the rotary drive in order to support the torque.
A method for introducing a drilling element into the soil using a drilling apparatus having a rotary drive, which is supported on a mast for introducing the drilling element arranged rotatably and slidably on the mast;
- at least one operating cylinder, a turning device having a collet that can be turned by means of the at least one operating cylinder, and a supporting bearing, wherein the turning device is supported on the mast by the supporting bearing through which the collet can be pivoted in the drilling direction and can be engaged with the drilling element driven by the rotary drive in order to support the torque the method comprising the steps of:
- setting the drilling element into rotation by means of the rotary drive and moving the drilling element along the mast;
- engaging the turning device with the drilling element;
- and
- applying a supportive torque to the drilling element through the turning device by means of the at least one operating cylinder.
Drilling apparatus for introducing a drilling element into the soil, the drilling apparatus comprising:
- a mast;
- a rotary drive, which is supported on the mast for introducing the drilling element arranged rotatably and slidably on the mast;
- at least one operating cylinder;
- and
- a turning device having a collet that can be turned by means of the at least one operating cylinder;
- a supporting bearing;
- wherein the collet has two clamping jaws which can be adjusted by means of a clamping cylinder between a clamping position and a free-running position and the turning device can be engaged with the drilling element driven by the rotary drive in order to support the torque.
