Definitions

  • the invention relates to an attachment tool device according to the preamble of claim 1.
  • An attachment tool device in the form of an attachment compressor is from the DE 20 2005 006 059 U1 known.
  • Such an attachment tool device is used as an excavator attachment, in particular in trench and pipeline construction.
  • quick-change devices and rotating heads as a cost-effective interchangeable device, they offer considerable potential for saving costs and increasing work safety, because people do not have to stay in trenches and pits for compaction work.
  • attachment tool devices are, for example, from the DE 10 2008 006 211 B4 known.
  • Various exchangeable attachments can be coupled to attachments of this type, depending on the intended use.
  • the monitoring of attached attachment tools is carried out by means of sensors that recognize the position or presence of coupling and locking elements and can output corresponding information to an operator, for example by means of a display.
  • the use of such a sensor system requires a high level of constructive effort, since existing components have to be adapted and the sensor system has to be installed in the attachment tool device in a damage-resistant manner. Programming is also required.
  • operating errors which can lead to dangerous situations for an operator, for example, cannot be completely ruled out.
  • the object of the present invention is to create an attachment tool device which can be used as universally as possible, with low acquisition and operating costs at the same time.
  • the attachment tool devices according to the invention generally have the advantage that they can have completely different compressor plates.
  • the attachment tool device can therefore be used very flexibly in different usage situations, for example in narrow or wide trenches with a corresponding narrow or wide compactor plate, with differently shaped compactor plates, or with a different surface on the underside of the compactor plate.
  • a worn compressor plate can also be easily replaced, and so can others Attachments, for example a screening bucket, can be coupled.
  • the housing of the attachment tool device also comprises an upper part.
  • the lower and upper parts are coupled to one another via buffer devices.
  • the lower part serves to connect the attachment tool; whereas the upper part includes the coupling with the excavator.
  • more complex geometries can be implemented in cast parts, which in turn enables the motor and / or unbalance generator to be arranged deeper in the position of use.
  • further receptacles for example for a locking device, can also be integrated directly into the cast part.
  • a bolt safety device when the bolt can be moved hydraulically, in particular, is provided.
  • An essentially one-piece cast part should be understood to mean, in particular, designs which are 60%, preferably 70%, preferably 80%, preferably 90% and preferably 100% formed as a one-piece cast part.
  • the remaining parts of the lower housing part can be provided as separate parts and also be designed as cast parts or as stamped or other parts. These are preferably also metal parts. These parts can then be materially, non-positively or positively connected to the cast part, in particular via welded or screwed connections.
  • the cast part can in particular have a base frame designed as a base and two side plate-like longitudinal members, which extend upward at an angle outwardly inclined from the base frame in a position of use and adjoin this, preferably on the side longitudinal edges of the base frame and a space between them lock in.
  • the inclination of the side members results in particular from the casting requirements in addition to the requirements resulting from the use, which should in particular also enable use with a narrow compressor plate, while at the same time providing sufficient stability when transitioning to the excavator.
  • the base frame can have a more complex shape in order to accommodate the various components, such as the locking device. in the In cross section, the base frame and the side member form a U-shaped design, in particular with inclined legs that point outwards.
  • Recesses for the drive and the unbalance generator (exciter unit) can be implemented directly without additional processing steps, such as burning or cutting, so that the manufacture of the lower housing part is simplified.
  • curves and transitions in cast parts can be better realized.
  • complex geometrical shapes deviating from the pure plate shape can be created without additional effort.
  • the unit for generating unbalance is part of the invention, through the cast part, to have the possibility, in particular, of relocating the unit for generating unbalance and preferably also a drive for this in the area of the base frame.
  • at least part of this unit is integrated into the area of the base frame and not arranged on it as was previously the case.
  • the recesses for the unbalance generator and / or drive extend into the base frame.
  • a locking device is provided as a locking device, there is no need for time-consuming screwing of the compressor plate to the housing, in particular the lower part.
  • Such a bolt is also particularly useful in the tough everyday use of an attachment tool device robust, and it is easier to manufacture than a rotation lock, for example.
  • the bolt has a conical active section. This makes the locking process easier (reduction of the risk of blockage) and creates a secure mounting of the compressor plate on the housing (clamping effect).
  • a central bolt is provided, which is arranged essentially between the two longitudinal beams.
  • the longitudinal beams preferably extend along the longer longitudinal sides, whereas the narrow sides preferably have no limitation in the vertical direction in the position of use.
  • the displacement path of the bolt essentially corresponds to the direction of the side members.
  • the bolt is preferably not above the even in the extended position Perimeter of the housing, preferably of the lower part, addition.
  • the locking device can be integrated into the base frame.
  • a mechanical safety device is provided which secures the attachment tool against falling when the locking device is unlocked (unsecured or unlocked state of the locking device) on the attachment tool device or its housing.
  • Such a configuration has the advantage that an unintentional loosening or falling of the attachment tool from the attachment tool device, e.g. as a result of incorrect operation, can be avoided, since the safety device secures the attachment tool independently of the locking state of the locking device on the attachment tool device. Even in the event of an undesired unlocking of the locking device due to incorrect operation, for example with the attachment tool device raised by an excavator arm, the risk of injury is considerably reduced in this way, since the attachment tool cannot, at least not completely, detach itself from the attachment tool device. This contributes to the safety in the operation of attachment tool devices with exchangeable attachment tools.
  • the attachment tool device can be an attachment compressor, for example.
  • the attachment tool can in particular be a compressor plate.
  • other components can also be coupled as attachment tools, for example a sieve bucket.
  • the attachment tool device can have an imbalance generator, in particular when configured as an attachment tool device.
  • the imbalance generator can be driven by a hydraulic motor which is connected to a hydraulic connection.
  • the securing device can be designed in such a way that it catches or intercepts the exchangeable attachment tool in a position which deviates from the position of the exchangeable attachment tool fixed on the housing.
  • the securing device can be designed as a collecting device, the replaceable attachment tool being caught outside of its fixing position or fixing position on the attachment tool device.
  • the safety device is not stressed or only negligibly stressed during normal operation (attachment tool correctly coupled to the attachment tool device), but only when it is actually required for safety reasons. In itself unnecessary loads or unnecessary wear can be avoided, which contributes to a long service life of the safety device.
  • the safety device can expediently be designed to be retrofittable. This not only allows retrofitting of existing attachment tools, but also an exchange of the safety equipment if necessary (spare parts supply).
  • the safety device can be retrofitted in particular by fastening it to the housing of the attachment tool device, for example by screwing or welding. It is particularly preferred if the safety device is integrally connected to the housing, in particular by being part of the cast part, in particular part of the base frame.
  • the safety device can be designed as a catch element which is fastened or provided on the housing of the add-on tool device and which is set up in such a way that it interacts (for catching the add-on tool) with a coupling section of the interchangeable add-on tool serving to fix the interchangeable add-on tool on the housing of the add-on tool device, e.g. one attached to the attachment tool preferably cylindrical rod.
  • a coupling section which is used to fix it to the attachment tool device and is therefore already present is used.
  • the catch element can partially grip around or behind the coupling section.
  • the catch element and coupling section can be spaced from one another and only rest against one another when the replaceable attachment tool begins to fall.
  • the catch element can, for example, have a hook-shaped cross section, with an opening being provided on the hook-shaped cross section, which opening is preferably oriented upwards (away from the fixed attachment tool).
  • the catch element can expediently be provided on a lower part of the housing, in particular on the base frame, in particular on a narrow side of the lower housing part.
  • a structurally favorable load introduction can hereby be implemented, since the lower part, in particular the base frame, is of stable design and is suitable for load transfer, since the attachment tool is also fixed and held there.
  • the type of coupling attaching the attachment on one side and locking on the other
  • an attachment tool can be fixed on the housing of the attachment tool device in two positions rotated by 180 °.
  • the housing of the attachment tool device can have a first connection section which interacts with a first coupling section (in particular a cylindrical rod) of the attachment tool, and a second connection section which interacts with a second coupling section (in particular cylindrical rod) of the attachment tool.
  • the connection sections are formed or attached to the housing of the attachment tool device and the coupling sections are formed or attached to the attachment tool.
  • the catch element can be arranged on the narrow side of the housing of the attachment device (attachment side), which faces away from the narrow side on which a bolt of the locking device used to fix the attachment tool to the housing acts (locking side). With this configuration, the process of coupling and changing the attachment tool are not impaired.
  • the catch element can have a first section (proximal section) extending parallel to the underside of the housing part or at an angle away from the lower housing part, and one on the first section adjoining second section (distal section) which is angled or curved relative to the first section.
  • the catch element is open at the top (away from the underside) and closed at the bottom (towards the underside). This enables the attachment tool to be reliably caught when it is released from the attachment tool device, since the catch element can catch the attachment tool even with a comparatively large release movement.
  • the catch element can overall have a hook-shaped cross section due to the first section and the second section.
  • the catch element can be arranged centrally with respect to the narrow side of the housing and / or the catch element can extend over a section of the narrow side of the housing.
  • the central arrangement of the catch element allows the attachment tool to pivot about the longitudinal axis of the coupling section, for example a cylindrical rod, but reduces the risk of tilting (sideways) towards the ends of the coupling section. If the catch element extends over a section of the narrow side of the housing, a sufficiently stable design of the catch element is created so that the attachment tool can be safely caught. Lateral tilting of the attachment tool towards the ends of the coupling section can also be counteracted.
  • the catch element (s) can extend, for example, over a range of 10 to 30 percent (together) of the width of the narrow side of the Housing extend.
  • the provision of two catching elements on both sides of a longitudinal center axis of the housing is particularly preferred, since in this way tilting can be avoided even more reliably.
  • the catch element of the safety device can be designed as a catch hook. This enables the attachment tool to be safely and reliably caught in the event of an undesired detachment of the attachment tool from the attachment tool device.
  • two spaced-apart receiving sections for receiving a rigid holding element of a means of transport can be formed on the attachment tool. This simplifies handling of the attachment tool and also of the attachment tool device as a whole, since simple handling by means of a lifting device, for example a forklift, is possible by means of the receiving sections.
  • the receiving sections can be designed, for example, as recesses in a side plate of the attachment tool.
  • the bolt preferably secures the second coupling section on the second connecting section.
  • the first coupling section is held on the first connecting section solely by the shape and orientation of the first connecting section, so that securing by means of the bolt provided according to the invention is only required on the second connecting section.
  • This configuration is inexpensive and stable and allows a quick one in everyday use Dismantling or mounting the compressor plate on the housing.
  • the bolt is advantageously actuated by a double-acting hydraulic cylinder by means of the hydraulic supply of the excavator. In this way, high locking forces can be generated which hold the compressor plate particularly securely on the housing, especially in conjunction with the conical active section.
  • the use of the excavator's hydraulic supply eliminates the need for a separate energy supply for locking the compressor plate to the housing. This makes the construction of the attachment tool device simpler and further costs are saved.
  • the imbalance generator interacts with a hydraulic motor that is connected to the hydraulic connection, and that a check valve is arranged between the second pressure connection and the hydraulic motor, which blocks the hydraulic motor.
  • the imbalance generator is only in operation when the first pressure connection is connected as a pressurized flow. If, on the other hand, the second pressure connection from the excavator is switched as a pressurized flow, the hydraulic motor is prevented from being driven by the check valve.
  • This operating state (stationary unbalance generator) can be used to change the compressor plate. This is particularly because, due to the use of the second pressure connection as a pressurized flow in the Attachment tool device a hydraulic pressure is available that can be used to operate the bolt.
  • the unbalance generator can work in one direction of rotation and in another direction of rotation. Normally, this is implemented in that the two pressure connections can be used either as a pressurized flow or as a pressureless return.
  • the attachment tool device In order to nevertheless be able to change the compressor plate of the attachment tool device in normal operation, the attachment tool device must be in an operating state in which the unbalance generator is not working. This is realized by an on / off valve which interrupts the flow of hydraulic fluid to or from the hydraulic motor, whereby the unbalance generator is switched off.
  • Non-return valves which can be hydraulically opened from the other pressure connection, ensure that the hydraulic lines are not completely depressurized or emptied when the hydraulic lines are switched off and the imbalance generator continues to run due to its inertia.
  • An attachment tool device carries in Figure 1 generally the reference numeral 10. It comprises a housing 12, which comprises a lower part 16 of the add-on compressor 10. Furthermore, an upper part 14 is provided. Upper part 14 and lower part 16 are connected to one another in a known manner by flexible buffer devices 18.

  • the lower part 16 is designed essentially as a one-piece cast part. Also considered to be an essentially one-piece cast part are those lower part designs 16 in which the lower part is at least 60% formed as a one-piece cast part and, for example, further parts are connected to it to form the lower part. Due to the provision as a cast part, the shape can be improved compared to previously welded parts so that the recesses 70 (here without the in Figure 2 shown cover 71) for the unbalance generator 20 and preferably also for the motor in the position of use can be shifted further down into the base frame 30, so that the housing 12 can be built flatter overall. In addition, casting molds enable geometric shapes that cannot be achieved using burn-out parts that are welded together. To make this clear, the upper edge of the base frame 30 is identified by the line provided with the reference number 31.

  • the catch element 62 is provided twice and, in relation to the narrow side 64 of the housing 12, is arranged centrally on both sides of the longitudinal center axis of the housing 12. As already indicated above, the catch elements 62 are designed as catch hooks 62.
  • the compressor plate 22 there are two spaced-apart receiving sections 76 for receiving one formed rigid holding element of a means of transport.
  • the receiving sections 76 are designed as recesses 76 in the longitudinal members 54a, 54b of the attachment tool 22. In this way, the compacting plate 22 and also the attachment tool device 10 as a whole can be handled in a simple manner by a lifting device, for example a forklift truck.
  • the safety device 60 operates as follows: The attachment of the attachment tool 22 to the attachment tool device 10 with safety device 60 takes place as described above. If the attachment tool 22 is properly positioned on the housing 16 and the locking device is locked (bolt 46 protrudes into the recess 36), the securing device 60 is not stressed. The rod 56b and the catch element 62 are then spaced from one another.
  • the compressor plate 22 begins to detach itself from the housing 12, for example as a result of incorrect actuation of the locking device, the compressor plate 22 begins a pivoting movement relative to the housing 12 about the longitudinal axis of the rod 56b due to gravity.
  • the second and curved or bent section 80 ensures that the rod 56b does not get out of the catch hook 62 "pops out".
  • the attachment tool 22 or the compressor plate 22 thus experiences a pivoting movement, but does not fall completely off the attachment tool device 10. This favors the safety in the operation of such attachment tool devices.
