Abstract

The invention relates to an earth working apparatus having an undercarriage which is designed as a running gear, and an upper carriage which is supported in a rotatable manner on the undercarriage and has a driver's cab as well as a drive motor for the undercarriage. According to the invention, between the undercarriage and the upper carriage an extension segment is arranged, through which a vertical distance between the undercarriage and the upper carriage is extended. On the extension segment between the undercarriage and the upper carriage a support means for tilt protection is mounted. The invention furthermore relates to a method for earth working with an earth working apparatus of such type.

First claim

The invention claimed is:

1. A drilling apparatus comprising:
an undercarriage, which is designed as a running gear,
an upper carriage, which is supported in a rotatable manner on the undercarriage and has a driver's cab as well as a drive motor for the undercarriage, and
a mast arranged on the upper carriage, along which a drill drive is supported in a vertically adjustable manner, wherein
the upper carriage is horizontally aligned with respect to the undercarriage defining a horizontal plane extending through the upper carriage,
between the undercarriage and the upper carriage, an extension segment is arranged, through which a vertical distance between the undercarriage and the upper carriage is extended, and
on the extension segment between the undercarriage and the upper carriage, a support and tilt protection device is mounted.

2. The drilling apparatus according to claim 1 , wherein
the extension segment is designed in a sleeve-shaped manner.

3. The drilling apparatus according to claim 1 , wherein the extension segment is non-rotatably connected to the undercarriage, and
the upper carriage is supported in a rotatable manner on the extension segment.

4. The drilling apparatus according to claim 1 , wherein
the support and tilt protection device has at least two carrier arms, which extend out from the extension segment in the horizontal direction, and
vertical supports are arranged on the carrier arms.

5. The drilling apparatus according to claim 4 , wherein
the carrier arms are directed contrary to each other and project laterally beyond the undercarriage.

6. The drilling apparatus according to claim 4 , wherein
the vertical supports each have a support foot, which is designed in a vertically telescopic manner.

7. The drilling apparatus according to claim 4 , wherein
the support and tilt protection device has four carrier arms, which are designed as a support cross.

8. The drilling apparatus according to claim 1 , wherein
the extension segment has a height of at least 0.5 m.

9. A drilling apparatus according to claim 8 , wherein the height is 1 m to 4 m.

10. The drilling apparatus according to claim 1 , wherein
the undercarriage is designed as a crawler-track running gear.

11. A method for drilling, in which on a ground around a working location an auxiliary device is arranged, which has a predetermined height with respect to the surface of the ground, wherein
for drilling, the drilling apparatus according to claim 1 is used, wherein the upper carriage with the extension segment has a distance to the surface of the ground which is greater than the height of the auxiliary device.

12. The method according to claim 11 , wherein
the drilling is carried out as a drilling operation and a bore is produced,
as the auxiliary device, a casing machine is provided around the bore as a working location, and
with the casing machine, at least one support pipe is introduced into the bore.
