Definitions

  • the present invention relates to a working device, in particular a mobile rotary drilling, piling or drilling device, according to the preamble of claim 1, a leader for such a working device and a set comprising a leader and an attachment.
  • the attachment is removed from the leader for transport and transported separately. This reduces the transport dimensions of the basic device with leader, but at the same time increases the transport effort and the associated costs.
  • the present invention is therefore based on the object of enabling simple and cost-effective transport of work machines of this type.
  • a working device in particular a mobile rotary drilling, piling or drilling device, which comprises a mobile undercarriage, an upper carriage, in particular rotatably mounted on the undercarriage, a leader mounted on the upper carriage and an attachment.
  • the leader is pivotably mounted on the upper carriage via a leader kinematics, so that it can be moved between an operating position with, for example (but not necessarily or exclusively) a vertical orientation and a transport position with, for example (but not necessarily or exclusively) a horizontal orientation.
  • the attachment can be stored in an operating position on a front of the leader facing away from the upper carriage, i.e. during operation the attachment is on the front of the leader.
  • the attachment can be removed from the front of the leader, for example in order to move the attachment into a transport position or, if necessary, to be able to switch between different attachments.
  • the leader comprises receiving means by means of which the attachment can be stored in a transport position for transport on a rear side of the leader facing the upper carriage.
  • the attachment can be removed from the operating position on the front of the leader and stored in a transport position on the rear of the leader for transport, with the leader providing suitable receiving means for this purpose.
  • the attachment is located in the transport position on the rear of the leader in the area between the leader and the ground, since there is typically sufficient space available here and the transport dimensions are not increased.
  • the leader is preferably offset to the side next to a driver's cab of the upper carriage, so that a transport position of the attachment located below the leader in the transport position on the rear of the latter does not impair the driver's visibility. This is particularly relevant in cases where the work device is not stored on a transport vehicle, but moves independently with the attachment in the transport position.
  • the attachment is stored stably on the rear of the leader.
  • attachment can remain on the leader or the base unit without the transport dimensions increasing or increasing significantly. This means that the attachment does not have to be transported separately, which reduces transport effort and costs.
  • the same support means could be used both for storing the attachment on the front of the leader (operating position) and for storing it on the rear of the leader (transport position).
  • symmetrical guide rails could be provided on the side of the leader, where the attachment (or a carriage carrying the attachment) partially surrounds the leader and is movably mounted on the guide rails.
  • the attachment would have to be separated from the guide rails, positioned on the back of the leader and reconnected to the side guide rails.
  • further connections e.g. bolt connections, could be provided to fix the attachment immovably in the transport position, since the attachment should not be movable in the transport position in particular.
  • the attachment has corresponding connecting means for connection to the receiving means.
  • first and second receiving means either the same connecting means can be connectable to both the first and the second receiving means.
  • the attachment or a carriage carrying it) could also comprise first connecting means for connection to the first receiving means and second connecting means for connection to the second receiving means.
  • the leader comprises a leader guide on which the attachment can be slidably mounted, in particular along a longitudinal axis of the leader.
  • the attachment can therefore be moved via the leader guide, in particular along the leader.
  • the leader guide has at least one guide rail extending parallel to the longitudinal axis of the leader, which can be arranged on the front of the leader or on the side of the leader.
  • the attachment (or, if it is mounted on the leader via an attachment carriage, the corresponding carriage) has guide rail receptacles which interact with the guide rails of the leader guide and fix the attachment in particular perpendicular to the longitudinal axis of the leader.
  • the drive for the movement of the attachment along the leader can be carried out in a manner known in principle from the state of the art by means of a hydraulic cylinder, feed cable or another drive.
  • the leader kinematics are designed to pivot the leader in a vertical pivot plane relative to the upper carriage. This allows the leader to be pivoted between the operating position and the transport position.
  • one or more hydraulic pivot cylinders are provided to pivot the leader.
  • the leader kinematics can be designed in such a way that they also enable pivoting movements of the leader out of the pivot plane mentioned, i.e. lateral tilting.
  • two hydraulic cylinders can be provided, the extension length ratio of which enables such a pivoting movement of the leader.
  • the leader In the transport position, the leader is aligned horizontally or essentially horizontally (i.e. with a slight inclination, for example forwards and downwards) so that the front of the leader points upwards.
  • the leader In the operating position, the leader can preferably assume several positions, for example a vertical position and positions tilted to the side within the swivel plane or to the side. All of these positions of the leader can be referred to as operating positions. This enables, for example, oblique drilling or the oblique insertion of sheet pile walls using an edge vibrator.
  • the attachment is arranged in the transport position on the rear of the leader between the leader and the ground and preferably in front of the upper carriage in the direction of travel. This makes optimal use of the available space without increasing the transport dimensions.
  • the receiving means are arranged at an end area of the leader.
  • the receiving means are located in the area of the end of the leader which forms the lower end of the leader when the leader is in a vertical position. If the leader is tilted backwards into the transport position, said end with the receiving means is therefore located in front of the upper carriage, in particular in the direction of travel, i.e. it protrudes forwards beyond the upper carriage.
  • the receiving means are designed to fix the attachment immovably to the leader in the transport position, wherein the receiving means preferably comprise bolt receptacles for establishing a bolt connection. This means that the attachment cannot move unintentionally during transport.
  • an additional locking mechanism can be provided which locks the attachment in the transport position. This can be operated manually or automatically.
  • the receiving means are arranged on the rear and/or side of the leader.
  • the receiving means or part of the receiving means are located on the side of the leader, but the attachment is still arranged on the rear of the leader in the transport position.
  • the leader is designed to be divisible and/or foldable and the receiving means are located on a base part of the leader that is permanently connected to the leader kinematics.
  • the present invention can also be combined with a foldable and/or divisible leader, as is known from the prior art, for example.
  • a A foldable leader can comprise two or more leader parts that can be pivoted or folded against each other, for example by means of hydraulic actuators.
  • the base part that is permanently connected to the leader can be rigidly or foldably connected to the leader kinematics and/or another leader part.
  • the attachment can be stored on an attachment carriage on the front of the leader and that the attachment and the attachment carriage each comprise connecting means for establishing a detachable connection between the attachment and the attachment carriage.
  • the attachment carriage can be permanently or detachably connected to the leader.
  • the connecting means for the detachable connection of the attachment and the attachment carriage preferably comprise bolt receptacles for establishing a bolt connection and/or suspension elements for establishing a suspension connection.
  • a combination of bolt and suspension connection elements can therefore also be provided, for example to first hang the attachment in the attachment carriage for pre-positioning and then bolt it and thereby finally secure it to the carriage.
  • the attachment carriage is mounted on the leader in a displaceable manner, in particular via a leader guide along a longitudinal axis of the leader.
  • the leader guide can, as explained above, have one or more guide rails, with the attachment carriage preferably comprising corresponding rail mounts.
  • the attachment carriage can be a feed carriage, which can be moved, for example, by means of one or more hydraulic cylinders and/or a feed rope and can apply a feed force directed downwards (or in the direction of the drilling tool), for example for drilling.
  • the attachment includes a work carriage to which the actual attachment is attached.
  • This work carriage can carry out the Have connecting means for connection to the attachment carriage mounted on the leader.
  • the attachment can be connected directly to the leader's support means.
  • the attachment carriage remains on the front of the leader, while the attachment is removed from the attachment carriage and stored in the transport position on the rear of the leader.
  • the support means could be designed in a similar way to the attachment carriage's connection means, so that the attachment is stored in the same way in the transport position and the same connection means of the attachment can be used for this as for connecting the attachment to the attachment carriage.
  • the working device i.e. in particular the leader and attachment carriage
  • the working device can be designed in such a way that the attachment including the attachment carriage can be removed from the leader and stored on the back of the leader in the transport position.
  • the attachment carriage can be connected to the leader's support means. The attachment does not have to be separated from the attachment carriage to move the attachment into the transport position.
  • the attachment comprises a drilling drive, for example a rotary drilling drive for Kelly drilling or a drilling drive for down-the-hole hammer drilling, a double-head drilling drive, a hydraulic hammer or a vibrator, in particular an upright vibrator or belt vibrator.
  • a drilling drive for example a rotary drilling drive for Kelly drilling or a drilling drive for down-the-hole hammer drilling, a double-head drilling drive, a hydraulic hammer or a vibrator, in particular an upright vibrator or belt vibrator.
  • the working equipment can be a construction machine for vibrating with an edge vibrator or belt vibrator, for impact with a hydraulic hammer, for wet mixing, for milling mixing, for down-the-hole hammer drilling, for Kelly drilling (normal or with low head), for double-head drilling, for continuous auger drilling or for full displacement drilling.
  • the invention further relates to a leader for a working device according to the invention.
  • the leader can be connected to a corresponding basic device, wherein the basic device preferably comprises a mobile undercarriage and an upper carriage mounted on it.
  • the leader comprises receiving means via which the attachment of the working device can be stored for transport on a rear side of the leader facing the upper carriage or on the side of the leader in a transport position.
  • the invention further relates to a set comprising a leader according to the invention and an attachment which can be stored in an operating position on the front of the leader and in a transport position via receiving means on the rear of the leader.
  • a set comprising a leader according to the invention and an attachment which can be stored in an operating position on the front of the leader and in a transport position via receiving means on the rear of the leader.
  • FIG. 1 a preferred embodiment of the working device 10 according to the invention is shown in a side view.
  • the embodiment discussed here is a working device 10 with an attachment tool 30 designed as a vibrator, more precisely an upright vibrator, although of course any other attachment tool can also be used.
  • the working device 10 comprises a base device with a mobile undercarriage 12, which in this embodiment has a crawler chassis.
  • a superstructure 14 is mounted on the undercarriage 12 so as to be rotatable about a vertical axis.
  • the Upper carriage 14 comprises a driver's cab 16 and a device for supporting the working machine (visible in the figure at the rear of the upper carriage 14).
  • a leader 20 is connected to the upper carriage 14 via a leader kinematics 24.
  • the leader 20 can be moved between a Figure 1 shown transport position, in which the leader 20 is mounted essentially horizontally, and an operating position.
  • the operating position includes in particular a vertical alignment of the leader 20, but can also include any inclined positions of the leader 20 that are made possible by the leader kinematics 24.
  • the pile driving material which can be grasped with a pair of tongs of the vibrator 30, can be introduced into the ground not only vertically, but also at a certain angle to the vertical.
  • the leader 20 has a front side 21 which faces away from the upper carriage 14 and in the transport position, as shown in the Figure 1 can be seen, points upwards.
  • the working device comprises an attachment 30, in the form of a vertical vibrator.
  • the attachment 30 is in an operating position on the front 21 of the leader 20 and can be moved in particular via a Figure 1 not shown movement mechanism along the leader 20.

  • the Figure 1 shows the transport position of the working device 10, in which the leader 20 is folded back over the leader kinematics 24 and the lower end of the leader 20 protrudes forwards over the upper carriage 14. In this position, the working device 10 can be transported, for example on a transport vehicle (not shown). If the vibrator 30 were to remain in its operating position on the front 21 of the leader 20, it would be in the Figure 1 above the leader 20 and would significantly increase the transport height of the attachment 10.
  • the invention provides a way of removing the vibrator 30 from the front 21 of the leader 20 and storing it in a transport position that is spatially separate from the operating position in a space-saving manner.
