Abstract
The present invention relates to an attachment for drilling and/or foundation work, in particular a casing oscillator or casing rotator, comprising a receiving apparatus for clamping at least one pipe and a drive for generating a rotational movement of the clamped pipe, wherein the attachment comprises at least one integral control unit for an independent carrying out of control functions of the attachment.
Claims14
An attachment for drilling and/or foundation work, comprising a reception apparatus for clamping at least one pipe and a drive for generating a rotational movement of the clamped pipe, wherein the attachment comprises
- at least one integral control unit having a control logic for an independent carrying out of at least one control function of the attachment and at least one communication interface for communication with a base machine, with the control unit invoking machine-relevant parameters of the base machine via the communication interface and/or providing machine-relevant parameters of the attachment via the communication interface,
- at least one transmission and reception unit is provided to enable a wireless and/or wired communication with at least one external unit, and
- at least one control function is the control of automatic movement routines for an automatic oscillating system and/or an automatic pipe drawing device.
A system comprising a base machine, including
- an excavating assembly for excavating a borehole, and
- at least one attachment installed at the base machine independently from the excavating assembly and for introduction of a casing into a around simultaneously with excavating, wherein
- the attachment comprises at least one integral control unit having a control logic for an independent carrying out at least one control function of the attachment,
- the excavating assembly comprises a grab for excavating the borehole, and
- the attachment is configured to rotate or oscillate the casing clamped thereto to introduce the casing into the ground by rotational movements synchronously to the excavation.
