Definitions

the invention relates to a drilling device for creating a vertical bore with a base body, arranged on a rear side of the body suspension for suspending the drill in the bore, a rotatably mounted about an eccentric removal unit, which on one side of the body eccentrically to a central axis of the body arranged and circumferentially mounted about the center axis, and a drive unit for rotationally driving the Abtragsech about the eccentric axis according to the preamble of claim 1. Furthermore, the invention relates to a method for creating a vertical bore.
Such a drill is for example from the DE 10 2008 028 997 A1 out.
This known drill has an approximately cylindrical housing which is sunk vertically into the ground.
Eccentric to the center axis of the drill a conical drilling tool is provided, which is driven by a motor rotating.
the individual drilling tool rotates planetary the center axis of the drill, wherein the distance between the eccentric axis of the drilling tool and the center axis of the drill is variable, so as to be able to cover the entire borehole bottom.
Such drilling tools with an eccentrically arranged removal tool are particularly advantageous for working in hard soil or rock.
conventional drilling tools with continuous cutting edges currently only a small area of the borehole bottom is always processed in the generic drills. This considerably reduces the load and thus the wear of the removal tool and of the entire drilling tool.
the invention has for its object to provide a drill and a method for creating a vertical bore, with which holes can be created very efficiently, even in hard soil material.
the drill according to the invention is characterized in that the Abtragsech is disc-shaped and that the eccentric axis of the disc-shaped Abtragsech angled at an acute angle to the borehole axis and / or to the center axis of the body is arranged.
the Abtragstician is arranged disc-shaped, so not provided with a defined, lying on the eccentric axis drill bit. Due to the eccentric and angewinkeite arrangement of the Abtragshim results in a kind of tumbling movement about the center axis, which usually corresponds to the drilling axis of the drill and thus a borehole axis. In this tumbling movement, only a constantly changing portion of the Abtragsaku with the soil to be removed is in contact. In this way, overheating of the removal unit and thus excessive wear can be avoided, since during the rotational movement individual peripheral areas of the disc-shaped removal unit are not or only slightly loaded depending on their rotational position.
a conical borehole bottom is produced by an acute angle of the eccentric axis with downward increasing distance to the center axis.
Such a Conical borehole bottom facilitates centering of the drill in the borehole. As a result, the leadership of the drill in the borehole is improved.
the acute angle is between 2 ° and 30 °, preferably 5 °.
a further improvement of the guide results according to a preferred embodiment of the invention in that at least one support element is arranged on the front side of the main body next to the removal unit, which is designed to rest on a bottom of the bore.
the support element is arranged with respect to the center axis opposite to the front side of the base body.
the support element is preferably rod-shaped. It is spring-mounted or telescopic. This can counteract unwanted tilting of the drill in the borehole and the orientation can be controlled.
a measuring device is provided on the support element for determining a bearing force of the drill.
corresponding force sensors may be present, by means of which the pressure force on the support element can be determined.
the compressive force on the support element allows conclusions about the bearing force of the opposing Abtragsaku. In this way, the pressing force and the speed can be matched to each other in a favorable manner, so that sets a high progress with low wear.
the removal unit can be a disk with ablation teeth arranged on the circumference.
a particularly preferred embodiment of the invention consists in that the removal unit has a carrier disk on which a plurality of removal tools are respectively mounted rotatably about a tool axis.
the removal tools can be designed as a roller chisel. Other removal tools are possible, such as multihammers (MHD).
MHD multihammers
the tool axes can be spaced and arranged transversely to the eccentric axis of the carrier disc of the removal unit. In this way, the rotating Abtragswerkmaschinemaschinee can roll on the bottom of the hole. This further improves the removal and wear behavior.
the removal tools can also be driven in rotation by a gear in the carrier disk.
the removal tools each have a plurality of Abtragszähne arranged.
the erosion teeth are arranged radially protruding to the outer periphery.
the removal tools preferably have a removal tip, so that there is substantially a punctiform, chisel-like contact with the ground. In contrast to linear cutting edges, this further improves the wear behavior.
the rotatable removal tools are driven circumferentially to the eccentric axis.
the circulating movement of the removal tools thus does not result as a rolling movement due to the rotation of the drilling apparatus as a whole, but is specifically effected by a drive, which is preferably arranged in the carrier disc of the removal unit.
the Abtragswerkmaschinee may also be milling discs, which are planetary driven around the eccentric axis circumferentially.
a suction opening is provided on the end face of the main body, via which abraded soil material can be suctioned off via a suction line from a bottom hole.
the drill can thus operate in a well filled with suspension or liquid bore. This not only serves to support the borehole wall. But the liquid also cools the Abtragswerkmaschinee, which is advantageous in the processing of hard rock.
the suction opening the removed soil material can be sucked together with surrounding liquid via a suction line. This extends through the body through to the back of the body.
a pump can be arranged in the main body itself and / or a pumping device can be arranged over days.
a good guidance and a high rate of drilling progress is achieved according to the invention in a preferred manner, that on the base body a torque arm is arranged, with which the base body relative to a surrounding wall of the bore can be supported.
the torque arm has a plurality of radially extendable support elements.
the radial extension can by means of hydraulic Cylinder or by a corresponding lever mechanism done.
at least part of the basic body is supported relative to the borehole wall so that reaction forces can be introduced directly into the borehole wall.
it is no longer absolutely necessary to supply a torque via a rigid drill pipe exclusively from above to the drill. This is particularly advantageous if larger drilling depths of 30 to 100 m and below are sunk.
the base body has a rear upper part and a front-side lower part, which are axially displaceable to each other, that on the upper part of the torque arm and the lower part of the Abtragsaku are arranged, and that a displacement device for axial displacement of the Lower part is provided relative to the upper part.
the rear upper part of the main body can thus be fixed via the torque arm in the radial and / or axial direction relative to the surrounding soil.
a displacement device which comprises in particular hydraulic actuating cylinder.
the torque is supplied via a rigid drill pipe from above ground.
the drive unit may be a gear which receives a torque from a central drill pipe and converts this into corresponding output torques for the removal unit, in particular for the removal tools. It can be achieved as a fixed ratio of the torques and speeds between the individual rotatably driven elements of the Abtragsaku.
the drive unit comprises a motor which is supplied with hydraulic and / or electrical energy.
the engine may be provided alternatively from the outside or in addition to the supply of torque.
the energy is supplied from over days via an electrical line or hydraulic lines.
a motor converts this energy into a mechanical rotary motion. It can according to the invention also a plurality of motors may be provided so that overall an individual adjustment of the speeds and torques of the individual driven elements is made possible.
