A ground drilling device has a drilling carriage which defines a drill string axis, a drill rod magazine for a plurality of rod sections, and a transfer device for the transfer of a rod section between the drill rod magazine and a position of the rod section in the direction of the drill string axis. The ground drilling device also has a guide on a top of the drill rod magazine that is configured to guide movement of the transfer device.

Ground drilling device and use of a ground drilling device

A Ground drilling device having a drilling carriage and a sled movable back and forth on the drilling carriage, wherein at least one gear is present for the drive of the sled, whose rotary movement is transformed into a linear movement by means of a rack, wherein a force relieving pathway is provided to relieve the gear of a radially introduced force.

A ground drilling device for drilling in soil by means of a drill string, wherein the ground drilling device comprises a drilling carriage and a sled movable in translation on the drilling carriage, and on the sled there is arranged a holder a) for the screwed connection of a rod section to the drill string, or b) for the screwed detachment of a rod section from the drill string, wherein the holder can move in translation relative to the sled in order to compensate for a change in the position of the holder caused by the screwing process.

Ground drilling device and method for drilling in soil

A ground drilling device having a drilling carriage, which defines a drill string axis, a first drill rod magazine for a plurality of rod sections and a transfer device for the transfer of a rod section between the first drill rod magazine and a position of the rod section along the drill string axis, wherein at least a first connection element is arranged at the first rod magazine and/or at the drilling carriage for the connecting of the first rod magazine to a second rod magazine such that the second rod magazine is arranged next to the first rod magazine.

Ground drilling device, system comprising a ground drilling device, method for earth drilling and use of a ground drilling device

The invention relates to a drive of a slide of an earth drilling device having a rotary drive and a pinion that is driven by the rotary drive and can be engaged with a rack, wherein the rotary drive is engaged with another pinion which can be engaged with the rack.

Drive of an earth drilling device, earth drilling device, and a method for driving an earth drilling device

A connecting device with a drive section having a thread on the end, wherein the connecting device can be used to screw a shaft element to a thread corresponding to the thread of the drive section, wherein, in addition to the thread, at least one positive-locking element forming a positive-locking connection with the shaft element is provided.

Connecting device

A connection mechanism has a drive section with a thread on one end and is constructed as a sleeve. A shaft element having a thread matching the thread of the drive section can be screwed together with the drive section. At least one interlocking element forming an interlock with the sleeve is provided in addition to the thread.

Connection mechanism

A drilling apparatus includes a drill rig which defines a drilling rod axis, a rod magazine for a plurality of rod sections, and a transfer device for transfer of a rod section from the rod magazine and for transfer of the rod section in the drilling rod axis. The transfer device is hereby constructed to travel in the direction of the longitudinal axis of the rod section in relation to the rod magazine.
