Definitions

  • the invention relates to a Erdbohr réelle with an undercarriage, which is designed as a chassis, and a superstructure, which is rotatably mounted on the undercarriage and a driver's cab and a drive motor for the undercarriage, according to the preamble of claim 1.
  • the invention further relates to a method for earth boring, in which an additional device is arranged on a floor about a processing point, which has a predetermined height relative to the bottom surface of the floor, according to the preamble of claim 11.
  • a generic Erdbohr réelle goes for example from the EP 1 418 152 A1 .
  • the mast with a mast guided and displaceable drill drive are arranged at a front, while at the opposite rear region of the upper carriage of the main drive motor and other drive units are arranged to balance the weight.
  • supporting feet may be attached to the superstructure in order to stabilize and support the earth-working device sufficiently in relation to the ground, in particular during machining operations with large force discharges. It is desirable to keep the overall center of gravity of the earthworking device as close to the ground as possible in order to reduce the danger of tipping.
  • a pipe rotating device is arranged at the lower end of the mast. This device is used for screwing in a drill pipe, which serves approximately to support the borehole wall.
  • a drill pipe which can also be used separately from the Erdbearbeitungs réelle, especially when the casing machine is relatively large.
  • a separate casing machine may have a height of a few meters.
  • a drill is used to further drill and excavate the soil material from the wellbore, often using a discontinuous drilling technique such as a bucket or a short auger.
  • To empty the drilling tool from drilled soil material it is necessary to pivot the superstructure of the drill again and again away from the borehole in an unloading position. During this pivoting, care must be taken that the rear of the superstructure does not collide with the upper end of the casing machine. Moving the undercarriage is undesirable because this would require a time-consuming readjustment of the earthworking implement at the borehole.
  • From the JP-A-2010-31523 is a drilling device with a boom out, on which a drilling tool is suspended on a rope.
  • a drive device is arranged on the ground around the wellbore.
  • the invention has for its object to provide a Erdbohr réelle and a method for earth drilling, with which even when using relatively large additional equipment at a tillage an efficient and safe working is achieved.
  • the earth working device is characterized in that between the undercarriage and the superstructure an extension segment is arranged, through which a vertical distance between the undercarriage and the superstructure is extended, and that on the extension segment between the undercarriage and the superstructure, a support device is mounted for anti-tip ,
  • a first aspect of the invention is to displace the superstructure overall relative to the undercarriage and to achieve a greater working height above the ground surface by interposing an extension segment.
  • the extension segment can be modular and even consist of several segment pieces. It can be set as a desired height. Larger conversions on the undercarriage or the superstructure are basically not necessary. Only the drive and supply strands between the uppercarriage and the lowercarriage, which are guided by the extension segment, are to be lengthened and adjusted accordingly.
  • Another aspect of the invention is to attach to the extension segment a support device for anti-tip. As a result, despite the increase in the center of gravity of the overall device sufficient tilting security is ensured.
  • the additional support means between the superstructure and the undercarriage reduces wear in the undercarriage during machining. Because the power flow takes place when the support device extended to a considerable extent on the support means and thus relieves the undercarriage and the numerous wheel bearings on the undercarriage. The improved rigidity also increases the machining accuracy during earthworking.
  • the extension segment is sleeve-shaped.
  • the drive and supply strands between the superstructure and the undercarriage can be performed within the sleeve-shaped extension segment.
  • extension segment is fixedly attached to the superstructure, so that the rotational movement takes place during pivoting of the superstructure between the extension segment and the undercarriage. It is also possible that by lifting the device as a whole by the support means of the undercarriage for a change in direction is rotatable.
  • a particularly simple embodiment is achieved according to a preferred embodiment of the invention in that the extension segment is rotatably connected to the undercarriage and that the superstructure is rotatably mounted on the extension segment.
  • the pivot bearing is moved upwards according to the superstructure.
  • a load on the bearing is kept low in particular by tilting moments. It can be arranged a pivot bearing also above and below the extension segment.
  • the support means comprise at least two support arms which extend in the horizontal direction away from the extension segment, and that vertical supports are arranged on the support arms.
  • the support arms extend in particular transversely to the longitudinal side of Erdbearbeitungs expertss. Because with a pivoting of the superstructure by 90 ° relative to the undercarriage is in this direction the greatest risk of tipping.
  • the support arms are directed opposite to each other and protrude laterally beyond the undercarriage.
  • the support arms thus extend in pairs offset by 180 ° to the center or pivot axis of the upper carriage. This also increases the buckling resistance of the expansion sleeve.
  • the vertical supports are arranged, which connect the support arms respectively to the ground.
  • the vertical supports can be arranged as a whole releasably at the outer end of the support arms.
  • a preferred embodiment of the invention is that the vertical supports each have a support leg, which is formed vertically telescopically.
  • the vertical supports can have an upper receiving sleeve, in which the support leg is displaceably mounted. This vertical telescoping can be done by hand or by means of an actuating cylinder.
  • the support means comprises support arms, which are formed as a support cross.
  • the support means in this case has a central support ring, which encloses the sleeve-shaped extension segment. From the outside of the support ring extending in the horizontal direction, the support arms and thus form a horizontal support cross.
  • extension segment has a height of at least 0.5 m, preferably 1 m to 4 m.
  • the undercarriage can be designed arbitrarily, be equipped with wheels.
  • a particularly advantageous embodiment is according to the invention in that the undercarriage is designed as a crawler chassis. This is particularly advantageous in rough construction site terrain and has a large contact surface and thus a high resistance to tipping.
  • the earth working device is designed as a drill with a mast, along which a drill drive is mounted vertically adjustable.
  • a so-called casing machine for separately screwing a drill pipe into the borehole can be provided as a supplementary device in a drill.
  • the casing machine may in particular be arranged separately from the soil working device.
  • a relatively large and high casing machine can thus also be used in a drilling rig without having to excavate a recess for the casing machine at each drilling point or erect a platform for the drilling rig.
  • the inventive method is characterized in that for earthworking an earth boring device, as described above, is used, wherein the superstructure with the extension segment to the surface of the bottom has a distance which is greater than the height of the additional device.
  • the earthworking is performed as drilling and a hole is made.
  • a casing machine be provided around the bore as a processing point as an additional device and that at least one support tube be introduced into the bore with the casing machine. It can thus be made a cased bore in an efficient manner.
  • an effective process management is achieved without separate recesses or pods would have to be created at the hole.
  • An inventive Erdbearbeitungs réelle 10 according to Fig. 1 has an undercarriage 12, which is designed as a crawler chassis.
