Definitions

  • a construction machine for civil engineering is formed with a chassis, arranged on the chassis leader for longitudinally displaceable guiding a drive head, the broker on the chassis about an at least approximately parallel to Gurklerlnaturesachse extending pivot axis is pivotally mounted, and a pivot drive for the driven pivoting of the leader about the pivot axis.
  • Such construction machines are for example from the DE-20020031 U known and can be used in particular as drilling and / or piling equipment.
  • the drive head is used to receive a drilling tool and can be designed, for example, as a rotary drilling head or percussion rotary head. By moving the drive head while the drilling tool is rotating at the leader, a hole is drilled.
  • the drive head serves as a holding element for sheet pile wall elements or other foundation element or tillage tools that are pressed by lowering the drive head along the leader in the ground.
  • the drive head may in particular have a vibrator.
  • a construction machine according to the invention can also be used as an injection device serve, in which case an injection tool is attached to the drive head.
  • a necessary positioning of the drive head with the there arranged sheet pile wall element or tillage tool in the horizontal can be achieved by moving the chassis together with the broker arranged thereon. Not least because of the large masses involved, however, this procedure is comparatively complicated. It is also possible to arrange the leader together with the drive head about an approximately horizontally extending pivot axis pivotally mounted on the chassis, wherein a pivot drive is provided for the active pivoting of the leader. This additional degree of freedom makes it possible to position the element to be introduced into the ground exactly in the horizontal without having to move the entire chassis.
  • the object of the invention is to develop a generic construction machine so that a particularly high precision in the positioning of the drive head and arranged thereon, to be introduced into the soil element is ensured even during the Einbringvorgangs itself.
  • a construction machine is characterized in that at least one locking element is provided, which between a first position in which it determines the leader about the pivot axis rotationally fixed to the chassis, and a second position in which the broker is released, is movable, and that an adjusting device for remote controlled operation of the locking element is provided.
  • a first basic idea of the invention can be seen in that at least one movable locking element is provided on the pivotable mounting of the leader, which in a first position hinders a relative movement of the leader to the chassis about the pivot axis. In a second position, however, the locking element releases the leader for rotation about the pivot axis on the chassis.
  • the locking element can be controlled remotely by means of an adjusting device, in particular by a driver's cab arranged on the chassis.
  • the locking element according to the invention absorbs the torques occurring during operation of the construction machine about the pivot axis and thus relieves the pivot drive.
  • the device according to the invention can with the device according to the invention an undesired pivoting of the leader about the pivot axis due to the operating forces occurring during tillage are effectively counteracted.
  • the invention makes it possible that the position of the drive head and the tool disposed thereon in the horizontal plane is maintained particularly accurate even during drilling operation, which allows a particularly precise tillage.
  • the adjusting device has at least one hydraulic drive.
  • an electric motor or another type of drive could be used for moving the locking element.
  • the hydraulic drive of the adjusting device may for example have an independent hydraulic linear motor, on which end the locking element is arranged.
  • an independent hydraulic linear motor on which end the locking element is arranged.
  • the locking element forms a hydraulic piston of the hydraulic drive.
  • the locking element itself is part of a hydraulic linear motor and hydraulic fluid is applied directly to the movable locking element itself to move this.
  • the number of movable components is reduced, thus increasing the reliability of the device according to the invention.
  • a particularly reliable operation of the construction machine according to the invention can also be ensured by the fact that the adjusting device with the locking element form a parking brake, which can also be referred to as a holding brake.
  • a parking brake which can also be referred to as a holding brake.
  • Such a holding brake sets the broker on the chassis in the absence of resource supply and opens only when supplies.
  • the adjusting device is preferably designed such that the locking element is moved in the first position at a pressure drop on the hydraulic drive.
  • Such a holding brake is thus hydraulically released.
  • a particularly simple and reliable construction machine according to the invention can be obtained by providing a spring, in particular a plate spring, for returning the locking element to the first position.
  • the locking force can be applied in a particularly simple manner by spring force.
  • the spring may in particular also be designed as a cup spring package.
  • a construction machine with a particularly accurately positionable broker can be obtained by providing at least one friction surface for the non-positive fixing of the leader on the chassis in the first position of the locking element on the locking element.
  • the brake can engage in any position of the leader.
  • At least one toothed element is arranged on the arresting element for the positive fixing of the leader on the chassis in the first position of the locking element.
  • the tooth element may be, for example, a tooth or a recess provided for receiving a tooth.
  • the broker has a shaft formed about the pivot axis, which is arranged from one on the chassis Sleeve is surrounded.
  • the chassis has a shaft formed about the pivot axis, which is surrounded by a sleeve arranged on the leader.
  • the locking element is suitably formed on the sleeve, but may in principle also be arranged on the shaft.
  • a particularly good locking effect with a simple construction can be given by the fact that the locking element is formed like a ring and surrounds arranged on the broker or on the chassis shaft.

  • a particularly good locking effect results suitably in that at least one disc element is arranged on the shaft, on which the locking element can be applied in the first position.
  • a plurality of disc elements and locking elements can also be provided.
  • a particularly high torsional strength of the leader is further ensured according to a preferred embodiment of the invention in that two contact surfaces are provided on the shaft, in particular on the disc element, wherein in the first position of the locking element, a first contact surface with the locking element and a second contact surface with the Sleeve is in contact.
  • the broker is fixed to the chassis at the first position of the locking element at two different locations.
  • a first non-rotatable Connection between broker and chassis is between the locking element and the shaft at the first contact surface.
