Device for producing a bore in the ground having - a carrier implement, - a mast supported on the carrier implement, - a carriage which is guided in a longitudinally displaceable manner on the mast and on which a drill drive is arranged for rotationally driving a drill string, - a drilling tool located on a lower end of the drill string, - a carriage drive for moving the carriage along the mast, wherein the carriage drive has a rope drive with a rope winch and a hoist rope, - a control means for controlling the carriage drive and - a sensor for determining a retraction force applied onto the carriage, - wherein the control means is designed to emit a control signal to the carriage drive, through which a load force of the drill string onto the borehole bottom can be set to a predetermined value, characterized in that - the sensor is designed as a load cell that is arranged on a dead rope end of the hoist rope on the mast, - in that, based on a retraction force and/or pressing force ascertained by the sensor on the dead rope end during the drilling process and an unladen weight of the drill string stored in a storage means, the control means is designed to ascertain a current value of the load force of the drill string, - in that the control means is designed, during the drilling process, to convey a difference of the current value of the load force and the predetermined value of the load force as a control deviation to a PID-controller that is designed to supply an actuating variable for the carriage drive, and - in that the PID-controller is designed to carry out two to one hundred iterative steps per second. - a carrier implement, - a mast supported on the carrier implement, - a carriage which is guided in a longitudinally displaceable manner on the mast and on which a drill drive is arranged for rotationally driving a drill string, - a drilling tool located on a lower end of the drill string, - a carriage drive for moving the carriage along the mast, wherein the carriage drive has a rope drive with a rope winch and a hoist rope, - a control means for controlling the carriage drive and - a sensor for determining a retraction force applied onto the carriage, - wherein the control means is designed to emit a control signal to the carriage drive, through which a load force of the drill string onto the borehole bottom can be set to a predetermined value, - the sensor is designed as a load cell that is arranged on a dead rope end of the hoist rope on the mast, - in that, based on a retraction force and/or pressing force ascertained by the sensor on the dead rope end during the drilling process and an unladen weight of the drill string stored in a storage means, the control means is designed to ascertain a current value of the load force of the drill string, - in that the control means is designed, during the drilling process, to convey a difference of the current value of the load force and the predetermined value of the load force as a control deviation to a PID-controller that is designed to supply an actuating variable for the carriage drive, and - in that the PID-controller is designed to carry out two to one hundred iterative steps per second.
