Definitions

  • the present invention relates to a working device, in particular a mobile rotary drilling, ramming or drilling device, according to the preamble of claim 1, a leader for such a working device and a set consisting of 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 the transport effort and the associated costs increase.
  • the present invention is therefore based on the object of enabling simple and cost-effective transport of generic work machines.
  • a working device in particular a mobile rotary drilling, ramming or drilling device, which comprises a mobile undercarriage, an uppercarriage, in particular rotatably mounted on the undercarriage, a leader mounted on the uppercarriage, and an attachment.
  • the leader is pivotally mounted on the superstructure via leader kinematics, so that it can be moved between an operating position with, for example (but not necessarily or exclusively) vertical orientation, and a transport position with, for example (but not necessarily or exclusively) horizontal orientation.
  • the attachment can be stored in an operating position on a front of the leader facing away from the superstructure, i.e. during operation the attachment is located 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. also to be able to switch between different attachments.
  • the leader comprises receiving means via which the attachment can be stored for transport on a rear side of the leader facing the superstructure or on the side of the leader in a transport position.
  • the attachment can be removed from the operating position on the front of the leader and stored for transport in a transport position on the rear of the leader or on the side of the leader, with the leader providing suitable receiving means for this purpose.
  • the attachment is preferably located in the transport position on the back of the leader in the area between the leader and the ground, as there is typically sufficient space here and the transport dimensions are not increased.
  • the leader is preferably located laterally offset next to a driver's cab of the superstructure, so that a transport position of the attachment located below the leader in the transport position on the rear does not impair the driver's visibility. This is particularly relevant for cases in which the implement is not stored on a transport vehicle, but moves independently with the attachment in the transport position. There is also a stable storage of the attachment on the back of the leader.
  • attachment can remain on the leader or on the basic device without the transport dimensions increasing or significantly increasing. This means that the attachment does not have to be transported separately, which reduces transport effort and costs.
  • the same receiving means are 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, with the attachment (or a carriage carrying the attachment) partially surrounding the leader and being 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 for example bolt connections, could be provided in order to immovably fix the attachment in the transport position, since the attachment should in particular not be movable in the transport position.
  • attachment or a carriage carrying it
  • first receiving means on the front of the leader can be fastened in the transport position via second receiving means on the back of the leader.
  • different receiving means are provided on the leader for storage at the front and for storage at the rear of the leader.
  • the first receiving means can represent or include guide rails.
  • the attachment has corresponding connecting means for connecting to the receiving means.
  • first and second receiving means either the same connecting means can be connectable to both the first and second receiving means.
  • the attachment or a carriage carrying it) could also include first connecting means for connecting to the first receiving means and second connecting means for connecting 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 preferably comprises at least one guide rail which extends parallel to the longitudinal axis of the leader and which is on the front of the leader or on the side Broker can be arranged.
  • the attachment (or, if it is mounted on the leader via an attachment carriage, the corresponding carriage) preferably has guide rail receptacles which interact with the guide rails of the leader guide and fix the attachment in particular perpendicular to the leader's longitudinal axis.
  • the drive for the movement of the attachment along the leader can be carried out in a manner known in principle from the prior art via a hydraulic cylinder, a feed rope or via another drive.
  • the leader kinematics are designed to pivot the leader in a vertical pivoting plane relative to the superstructure. This allows the leader to be pivoted between the operating position and the transport position.
  • one or more hydraulic swivel cylinders are provided to swivel the leader.
  • the leader kinematics can be designed in such a way that it also enables pivoting movements of the leader out of the said pivoting plane, 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 in particular horizontally or essentially horizontally (i.e. with a slight inclination, for example forward and downward), 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 as well as within the pivot plane or positions tilted laterally thereto. All of these positions of the leader can be referred to as the operating position. This makes it possible, for example, to drill slanted holes or insert sheet pile walls at an angle using an upright 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 superstructure in the direction of travel.
  • the receiving means are arranged at an end region 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 erected vertically. If the leader is tilted backwards into the transport position, said end with the receiving means is therefore in front of the superstructure, particularly in the direction of travel, i.e. it protrudes forward beyond the superstructure.
  • the receiving means are designed to immovably fix the attachment to the leader in the transport position, the receiving means preferably comprising bolt receptacles for producing 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 back 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 back 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, for example, from the prior art.
  • a foldable leader can comprise two or more leader parts that can be pivoted or folded relative to one another, for example by means of hydraulic actuators.
  • the base part which 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 via an attachment carriage on the front of the leader and the attachment and the attachment carriage each include connecting means for producing 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 releasably connecting the attachment and attachment carriage preferably include bolt receptacles for producing a bolt connection and/or suspension elements for producing a suspension connection.
  • a combination of bolt and suspension connecting elements can also be provided, for example in order to first hook the attachment into the attachment carriage for pre-positioning and then bolt it and thereby finally fix it to the carriage.
  • the attachment carriage is mounted on the leader in a displaceable manner, in particular in a manner displaceable along a longitudinal axis of the leader via a leader guide.
  • the leader guide can have one or more guide rails, with the attachment carriage preferably comprising corresponding rail receptacles.
  • 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 cable and, for example, can apply a downward feed force (or towards the drilling tool) for drilling.
  • the attachment includes a work carriage to which the actual attachment is attached.
  • This work carriage can have the above-mentioned connecting means for connection to the attachment carriage mounted on the leader.
  • the attachment can be connected directly to the leader's receiving 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 receiving means could be designed analogously to the connecting means of the attachment carriage, so that the attachment is stored in the transport position in the same way and the same connecting 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 the attachment carriage
  • the working device can be designed in such a way that the attachment together with 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 receiving means. To move the attachment to the transport position, the attachment does not have to be separated from the attachment carriage.
  • the attachment comprises a drilling drive, for example a rotary drilling drive for Kelly drilling or a drilling drive for down-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-hole hammer drilling, a double-head drilling drive, a hydraulic hammer or a vibrator, in particular an upright vibrator or belt vibrator.
  • the working device can be a construction machine for shaking with an upright vibrator or belt vibrator, for hitting with a hydraulic hammer, for wet mixing, for milling mixing, for down-the-hole hammer drilling, for Kelly drilling (ordinary 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, the basic device preferably comprising a mobile undercarriage and a superstructure mounted thereon.
  • the invention further relates to a set consisting of 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.
  • the attachment can be designed according to one of the exemplary embodiments given above.
  • FIG. 1 a preferred embodiment of the working device 10 according to the invention is shown in a side view.
  • the exemplary embodiment discussed here is a working device 10 with an attachment tool 30 designed as a vibrator, more precisely an upright vibrator, although any other attachment tool can of course also be used.
  • the working device 10 comprises a basic device with a mobile undercarriage 12, which in this exemplary embodiment has a crawler chassis.
  • a mobile undercarriage 12 On the lower frame 12, an uppercarriage 14 is rotatably mounted about a vertical axis.

  • the operating position includes in particular a vertical orientation of the leader 20, but can also include any inclined positions of the leader 20, which are made possible by the leader kinematics 24.
  • the ramming material which can be grasped with the tongs of the vibrator 30, can not only be introduced vertically into the ground, but also at a certain angle to the vertical.
  • the leader 20 has a front 21, which faces away from the superstructure 14 and in the transport position, as in the Figure 1 can be seen, pointing upwards.
  • the working device includes an attachment 30, in the present case in the form of an upright vibrator.
  • the attachment 30 is in an operating position on the front 21 of the leader 20 and can in particular have a position in the Figure 1 Movement mechanics, not shown, can be moved along the leader 20.

  • the Figure 1 shows the transport position of the implement 10, in which the leader 20 is folded backwards via the leader kinematics 24 and the lower end of the leader 20 protrudes forward over the superstructure 14. In this position, the implement 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 arranged above the leader 20 and would significantly increase the transport height of the attachment 10.
  • the invention provides a possibility of removing the vibrator 30 from the front 21 of the leader 20 and storing it in a space-saving manner in a transport position that is spatially separate from the operating position.
