Method for operating a horizontal drilling device and horizontal drilling device
First Claim
1. A horizontal drilling device comprising:
- a linear drive;
a rotational drive which is displaceable by the linear drive; and
a drill rod assembly,wherein the rotational drive forms a through opening into which the drill rod assembly is insertable,wherein the rotational drive includes a force transmission ring for form fittingly transmitting to the drill rod assembly,wherein the force transmission ring is configured so that in a first angular position of the force transmission ring relative to the drill rod assembly, the drill rod assembly is insertable into or removable from the rotational drive and in a second angular position of the force transmission ring relative to the drill rod assembly, the drill rod assembly is locked, thereby enabling transmission of the forces,wherein the force transmission ring forms an opening through which the drill rod assembly is passable, andwherein the drill rod assembly has at least in one first section a first cross section which corresponds to a cross section of the opening formed by the force transmission ring, so as to enable passage of the drill rod assembly through the opening only in the first angular position, and wherein the drill rod assembly, in at least one second section, which is formed as a subsection of the first section, has a second cross section so as to enable rotation of the drill rod assembly into the second angular position only when the second section is located within the opening formed by the force transmission ring.

Abstract
A method for operating a horizontal drilling device includes the steps of fixing a rod assembly section within a through-opening formed by a rotational drive of the horizontal drilling device, and connecting the rod assembly section to a rear end of a drill rod assembly of the horizontal drilling device or releasing the rod assembly section from the drill rod assembly by a linear and/or rotational movement of the rotational drive, wherein force transmission means for transmitting compressive and/or pulling forces and/or a rotational torque to the drill rod assembly are provided in the through-opening, wherein the rotational drive is displaceable by a linear drive of the horizontal drilling device, and wherein the drill rod assembly is configured as rod assembly string and is composed of a plurality of interconnected rod assembly sections.
