Embodiment Construction

[0028] Figures 1 and 2 show a first drilling device 10 according to the invention having a base 12 in which a container-shaped power pack 14 for energy and hydraulic power sources is arranged. At the opposite end of the base 12 there is provided a forked ground support 16 extending around the drilling frame 5 . On the support of the forked ground support 16 a mast 23 is pivotably articulated by means of a V-shaped bipod 20 . On the rear side of the mast 23 facing away from the drilling frame 5, said mast is supported relative to the foundation 12 by a strut arrangement 18 with a so-called A-trestle.

[0029] At the transition from the mast 23 to the bipod 20, a generally horizontally extending drill floor 22 with a box-like console 62 is installed. Below the drill floor 22 supported by the struts 21 relative to the forked ground supports 16, blowout-preventers 60 are provided in known manner with corresponding clamping means for screwing and disconnecting the individual rods ...

Abstract

The invention relates to a drilling device and a related drilling method, in which provision is made for a mast, a drilling carriage that is guided along the mast in a displaceable manner and a drive unit for moving the drilling carriage on the mast. In accordance with the invention the drive unit has both a hydraulic cylinder drive and a rope winch drive. The drilling carriage can be coupled with the hydraulic cylinder drive and with the rope winch drive.

Description

technical field [0001] According to the preamble of claim 1 , the invention relates to a drilling arrangement comprising a derrick, a drilling carriage displaceably guided along the derrick, and a drive unit for moving the drilling carriage on the derrick. [0002] The invention also relates to a drilling method for producing a borehole, wherein a first rod and a second rod are moved and in particular introduced into the ground with a drill frame guided on a derrick. Background technique [0003] In drilling rigs of the type employed especially in deep hole drilling, there are generally two main modes of operation. This involves drilling on the one hand and lining the borehole with casing on the other. The first main mode of operation, which requires the largest part of the operating time, is for drilling or extraction of drill pipe sections. In this case, the rod sections must be replaced quickly because the drilling well flushing is interrupted during this time. There i...
