- the invention relates to an apparatus, a method and a system for feeding and discharging drill string to a drilling apparatus in a drilling rig for creating a deep hole. Furthermore, the invention relates to components of the system in the form of a stacking yoke for the batch arrangement of boring bars and a device for separating a boring bar from a batch of boring bars arranged parallel to one another.
- a drilling tool driven by a drill string consisting of a drill string is used.
- the entire drill string must be removed from the borehole and, after a new drilling tool has been provided, reinstalled.
- the drill rods of the drill string for example, in large systems, in each case to two or three pieces removed and installed at once, and placed in the tower of the rig upright. If this camp is full in the tower, then the boring bars that are still to be removed or installed must be removed from the drilling rig.
- drill rods As such, as drilling progresses, additional drill rods must be added to the drill string as drilling progresses. These drill rods are fed from the outside.
- a pipe bearing is provided in addition to the drilling rig. This pipe storage is over an inclined plane
- CONFIRMATION COPY connected to the drilling rig.
- the drill pipe is transported via this inclined plane by means of a lifting device in the drilling rig, and then supplied with the lifting device of the drilling rig and installed. This procedure is associated with a lot of manual work and the risk of injury.
- the storage location for the drill rods outside of the drilling rig involves a large well site, which is not necessarily beneficial in certain applications.
- the object of the invention is therefore to provide a device that automates the supply and removal of drill pipe from a receiving position to a dispensing position and provides this in a simple way safely and quickly with low maintenance.
- the inventive solution with regard to the device for feeding and discharging drill pipe provides a device for feeding and discharging drill pipe to a drilling device in a drilling rig for creating a deep hole having a base on which a boom is rotatably arranged, so that the boom is pivotable about a pivot point having a receiving unit, which is designed so that a drill string is receivable at a receiving position and is deliverable at a dispensing position, and which is rotatably arranged relative to the boom, and having a drive unit, which at its one End is operatively connected to the base and which is at its other end operatively connected to the boom, wherein the receiving unit is connected to a positive guide, which is designed so that the receiving unit by operating the drive unit and the associated pivoting of the boom to the fulcrum of the recording Movement is moved to the dispensing position.
- the advantage here is that, due to the forced operation, a safe under all conditions feeding the boring bars fromconcentrbohrort to the delivery without additional control and regulatory effort
