Definitions

  • the invention relates to a method for civil engineering, in which a tool is lowered and thereby guided by means of a telescopic linkage, which has an outer rod, in which at least one inner rod is slidably received.
  • the invention further relates to a device for civil engineering with a mast and a telescopic linkage disposed thereon, at one end of a tool is attachable, wherein the telescopic linkage has an outer rod, in which at least one inner rod is slidably received.
  • a generic prior art for example, from the EP 0 947 664 A out.
  • a telescoping drill string which is also known as a so-called kelly linkage.
  • an outer tube which is connected to a rotary drive on a mast, a plurality of inner rods are arranged telescopically.
  • the first telescopic rod is still connected to a crane rope through which the innermost rod and all other rods can be lowered down.
  • the telescopic length is limited in this known system by the diameter of the outer tube.
  • the diameter of the outer tube in turn can not be increased arbitrarily, since this must be taken in the rotary drive.
  • the invention has for its object to provide a method and an apparatus and a suitable telescopic linkage, which can be achieved with a further reliable leadership and larger processing depths.
  • the tool is mounted on the outer rod and is lowered with this and that initially with the outer rod only an inner rod is lowered, which is then pulled by means of a slidably guided on the mast carriage element from the outer rod.
  • a basic idea of the invention is based on the one that the tool is directly attached to the outer rod and the outer rod is lowered with the tool. It is thus achieved a reverse telescoping movement as in a conventional Kelly bar.
  • the inner narrow telescopic rod remains at the top, so that regardless of the length of the telescopic linkage readily a connection to a rotary drive or other drive can be made.
  • an almost arbitrary number of inner rods can be provided by appropriate enlargement of the lowerable outer tube.
  • the outer rod can be hung on a crane rope, which receives the weight of the entire rod and an attached tool, such as a drilling tool or a milling cutter.
  • the invention provides a special telescoping, in which first the outer rod is lowered to a predetermined depth. It is then by means of a special carriage element one or more inner rods pulled out to the top.
  • the carriage element itself can be moved via a separate winch on the mast or via a rack drive or a similar drive. The pull-out movement can also take place along the mast, which ensures good guidance of the telescopic linkage.
  • the inner rod is pulled out of the outer rod up to a locking position, in which the outer rod is rigidly connected to the adjacent inner rod, and that the outer rod and the inner rod rigidly connected thereto are further lowered.
  • the locking can be done by suitable locking means, such as bolts or locking locks.
  • a preferred development of the invention is that for further lowering of the rigidly connected to the outer rod inner rod at least one further inner rod is pulled out by the carriage member to the locking position and rigidly connected and that the steps of lowering, pulling out and connecting optionally be repeated so long until the telescopic linkage is extended. By this procedure, a particularly long telescopic rod can be pulled out reliably.
  • a further preferred embodiment is that a piecewise lowering takes place in each case up to a defined pulling position, on which then one or more inner rods are pulled out by means of the carriage. It is particularly preferred that the pulling position above a soil surface, in particular in the lower region of the mast, is provided. Thus, the one or more inner rods can be locked respectively in the extended position above the ground.
  • the close tolerance region of the joint will not be contaminated by any existing suspension in a drilling or milling hole created or by sand and gravel from the soil. This ensures a dimensionally accurate locking and protects the precisely machined Guiding and locking areas of the individual bar elements.
  • the carriage member is brought to process the outer and / or inner rod with this.
  • the carriage element may have a gripping or holding device which engages positively and / or non-positively in corresponding gripping regions on the respective rod.
  • the lifting and lowering of the civil engineering tool arranged on the telescopic linkage can in principle be effected exclusively by way of a carrying cable by means of a cable winch on the device.
  • the carriage element is used during lowering and lifting of the tool. As a result, larger forces can be achieved in addition to the winch of the carriage element and a total of a higher processing speed.
  • the rigid connection between the individual rod elements can be done in the simplest way by hand, such as using screw or socket pin.
  • a production and / or release of the rigid connection of the telescopic linkage takes place automatically.
  • hydraulically or pneumatically adjustable retaining bolts can be provided, or semi-automatic latching devices which automatically assume a latching position when a latching position is reached, for example by an applied spring force.
  • the telescopic rod is rotated, in particular driven in rotation.
  • a rotation about a defined angle of rotation is useful, for example, in the manufacture of slot walls by means of diaphragm wall grippers.
  • the telescopic linkage can also be used to drive augers, in which the telescopic linkage via a rotary drive on the mast is rotated to transfer the drilling torque to the tool.
  • the outer rod is connectable to the tool and that on the mast, a slide member is slidably guided, which is designed for holding and moving the at least one inner rod relative to the outer rod.
  • the carriage element may have a gripping device for gripping and / or holding the rods.
  • the gripping device may for example comprise a hydraulically or pneumatically operated collet for positive and / or non-positive gripping of the rods or only a simple stop ring.
  • a particularly economical embodiment of the invention is that the tool is suspended with the telescopic rod on a rope.
  • the rope can be operated via a winch, which is arranged and driven for example on a mast carrying the carriage.
  • a winch which is arranged and driven for example on a mast carrying the carriage.
  • Such a cable drive is located on most conventional construction machines. With these high forces can be achieved even at high processing depths.
  • the tool to be operated with the telescopic linkage itself has one or more drives, as is the case, for example, with a trench cutter for the cutting wheel drive or a trench wall grab, which require a hydraulic or electrical energy supply
  • a hose feed with at least a Schlauchumlenkrolle is provided, which is guided displaceably on the mast.
  • the drill pipe can be used for a wide variety of tools, including measuring tools.
  • the tool is a milling cutter, a gripper or a drilling tool.
  • a rotary drive is provided for rotating the telescopic linkage.
  • the rotary drive is usually arranged on the mast and surrounds the telescopic rod.
  • a Te-telescopic linkage is provided with an outer rod and one or more inner rods, which are adjustable between a retracted position and an extended position, in which the rods are connected to each other via connecting portions.
  • a telescopic linkage is provided that are arranged on the connecting portions locking elements.
  • the locking elements may be plug or bolt as a simple design.
  • bolts can also be operated semi-automatically or fully automatically.
  • connection areas is arranged at the free ends of the rods and that only the connection areas are processed for guiding and position positioning.
  • simple steel pipe elements can be used, which do not have to be worked over the full length. Instead, mechanical processing takes place only on the inside and / or outside at the end regions of the rods. In these areas, a good and very precise machining is possible without major expense. Overall, a play-free connection between the rods can be achieved.
  • rod elements made of solid shell material or struts having lightweight components with a wide variety of cross-sectional formats, in particular round or rectangular cross-sections can be used as rod elements.
  • a preferred embodiment is that rods are closed tubes and that sealing elements are arranged at the connection areas.
  • the arrangement of sealing elements on the locking areas in conjunction with a locking of the rod elements outside the wellbore in a clean environment, penetration of water, support suspensions or soil materials can be reliably prevented in the interior of the telescopic boom.
