Description

The present invention relates to an excavator / work implement with removable auxiliary implement, in particular for performing lumbering or road or landscaping work, comprising an undercarriage with a crawler undercarriage, the crawler undercarriage on both sides of an undercarriage base each comprising at least one crawler chassis unit, and a on the undercarriage base about a substantially vertical first axis of rotation rotatable superstructure with an excavator / working arm.

Such an excavator / work device is from the EP 0 663 478 A1 known. In this excavator / working device, an excavator constructed essentially in a conventional construction with a superstructure and an undercarriage is combined with a vibrating device, which is variably provided on the undercarriage in its vertical position. Trained with a crawler undercarriage excavator can also be used with supportive use of an excavator provided on the excavator bucket for distribution of the vibrating device to be compacted bulk material in road construction to prepare the substrate for a concrete pavement or the like.

It is the object of the present invention to provide an excavator / working device with removable additional working device, in which with increased flexibility in terms of the area of application, a relief of the surface traveled by such an excavator / working device can be achieved.

According to the invention, this object is achieved by an excavator / work implement with removable auxiliary implement, in particular for carrying out lumbering or road or landscaping work, comprising an undercarriage with a crawler track undercarriage, the crawler track undercarriage each comprising at least one crawler undercarriage unit on both sides of an undercarriage base; a superstructure rotatable on the undercarriage base about a substantially vertical first axis of rotation with an excavator / work arm.

It is further provided that the crawler undercarriage units on the undercarriage base in its pivotal position relative to the undercarriage base are supported variable about a substantially horizontal first pivot axis, that the superstructure is arranged in a first longitudinal region of the undercarriage base, and that the undercarriage in a second longitudinal region of the undercarriage base for receiving a pivotable about a substantially horizontal pivot axis and removable from the undercarriage settling and dumping is designed as an additional working device.

In the structure according to the invention, two aspects are used in combination, which, above all, also result in an efficient discharge of the subsurface when combined. Firstly, the crawler tracks are provided on the undercarriage base pendulum and can therefore adapt to uneven ground configurations. It is thus achieved a consistent, at least not leading to overload distribution of the surface load. On the other hand, a further work functionality is integrated into the device according to the invention, in particular by the possibility of being able to provide a skip-dumping bridge on the undercarriage, so that driving on the processed terrain can be avoided or at least reduced, for example by lorries designed as dumpers.

In a particularly advantageous development, it is proposed that the settling and tilting bridge is associated with a movement drive for pivoting the same about the second pivot axis and / or for displacing the same with respect to the undercarriage.

In order to keep the structure as simple as possible, the movement drive can include the excavator / working arm.

For a defined positioning of the settling / tilting bridge, but also other additional tools, it can be ensured that on the undercarriage base a first additional implement carrier arrangement for receiving the settling and tilting bridge is provided on the undercarriage.

In this case, the flexibility in use can preferably be increased further by virtue of the fact that the first additional implement carrier arrangement is rotatable about a substantially vertical second axis of rotation, preferably in a rotational angle range of 360 °.

In order to realize the picking and unloading of the settling / tilting bridge in a simple manner, it is proposed that at least one roller assembly with at least one rotatable about an axis of rotation roller is provided on the undercarriage and that the settling and tipping bridge about an axis of rotation of the roller assembly as second pivot axis is pivotable and / or slidable on the roller assembly. It is possible to use the settling and tilting bridge in the tilting operation in a simple manner when the settling and tipping bridge is locked with respect to the roller assembly and in the locked state with at least one roller of the roller assembly about its axis of rotation as the second pivot axis is pivotal and against displacement the roller assembly is held.

For example, a first roller arrangement may be provided on the first auxiliary implement carrier arrangement.

In particular, in road construction or landscaping, but in principle also for the reprocessing of Mohr and forest soils, it may be advantageous if at least in an end portion formed by the second length range a height-adjustable dozer blade is provided on the undercarriage base, thus also a part of the undercarriage.

On the dozer blade, a second auxiliary implement carrier assembly may preferably be pivotally supported about a substantially horizontal third pivot axis with respect to the dozer blade. This makes it possible to provide additional auxiliary equipment which further increases the variability in the field of use.

On the dozer blade, preferably the second additional implement carrier arrangement provided thereon, a second roller arrangement can be provided, via which the settling / tilting bridge can be received or set down. Since in general the dozer blade is adjustable in height, it is thus possible to adjust the support area for the settling and dumping in height.

When the crawler undercarriage extends substantially over the entire first length range and second length range, it is ensured that the device according to the invention is supported on the ground substantially over its entire extension length, which contributes to a further reduction in the surface load.

According to a further aspect, the invention relates to a device for pivotally locking a settling and tilting bridge on a support assembly, comprising at least one roller assembly with at least one rotatable about an axis of rotation and movable in the direction of the axis of rotation of the roller assembly, wherein in a locked state the at least one roller is pressed in the direction of an abutment on a Absetz-tilting bridge and is pivotable together with the Absetz-tilting bridge about the axis of rotation.

With such an arrangement, it is easily possible to lock a settling and tilting bridge in a simple manner, using this lock, however, to be able to operate the tilting bridge in tilt mode.

In this case, it may be provided, for example, that the roller arrangement comprises two rollers movable in opposite directions to each other in the direction of the rotation axis, wherein the rollers are movable in opposite directions relative to each other and in abutment against a respective abutment on a settling and tilting bridge in a first direction of relative movement and to cancel the locking state of one of the first relative movement direction opposite second relative direction of movement and away from the respective abutment are movable.

The present invention will be described below in detail with reference to the accompanying drawings. Show it:

1 a side view of an excavator / working device according to the invention;

2 an illustration of a telescopic roller assembly for a settling and tipping bridge;

3 to 24 various additional tools, which are connected to the in 1 shown excavator / working device in different areas of the same can be attached.

In 1 is an inventive excavator / working device 10 shown in a schematic representation in side view. The excavator / working device 10 can be used in various work areas, depending on which of the additional tools described below is provided. A preferred area of application is lumbering in the forest, in which fell trees, cut and transported away and if necessary, the forest soil must be reprocessed. Furthermore, it is of course possible to use such an excavator / work equipment in road construction or landscaping or anywhere where earth or scree or concrete masses must be moved or edited.

The excavator / working device 10 includes a generally with 12 designated undercarriage with an undercarriage base 14 , At the undercarriage base 14 is a crawler chassis 16 provided on both sides with respect to a undercarriage longitudinal direction R respectively at least one, in the example shown, a crawler chassis unit 18 having. On each crawler track unit 18 is not shown via drive or deflection wheels a crawler 20 guided. By driving the caterpillars 20 the crawler tracks 18 can the excavator / work device 10 be moved forward.

The at the undercarriage base 14 provided crawler tracks 18 are, as indicated by an arrow P ₁ , on the undercarriage base 14 about respective pivot axes S ₁ pivotally supported or pendulum. Here, it is preferably provided that the substantially horizontal pivot axis S ₁ for the two on both sides of the undercarriage base 14 provided crawler tracks 18 is identical. It should be noted here that the term "horizontal" refers to a situation in which the excavator / work implement 10 standing on a substantially flat and horizontally oriented ground. Of course, the pivot axis S ₁ at inclination of the excavator / working device 10 assume in the inclined terrain a correspondingly inclined positioning relative to a horizontal in the earth coordinate system, which nevertheless is to be understood in the sense of the present invention as a substantially horizontal orientation of this pivot axis S ₁ .

It can be seen that the pivotal mounting of the crawler tracks 18 on the undercarriage base 14 is provided near an end portion thereof, preferably an end portion in which on the undercarriage base 14 a general with 22 designated upper carriage is rotatably supported about a substantially vertical axis of rotation D ₁ in a rotation angle range of 360 °, so that the superstructure 22 in its arbitrary rotational position with respect to the undercarriage 12 can be positioned. This can be done on the undercarriage 12 or the undercarriage base 14 a rotary feedthrough or a turntable 24 be provided so that the superstructure 22 in defined positioning with respect to the undercarriage 12 can be arranged and equally on the undercarriage 12 provided equipment and in particular the crawler track undercarriage 16 by the generally in the superstructure 22 provided drive can be operated.

To the pivotability or Pendelbarkeit the crawler chassis units 18 with respect to the undercarriage base 14 to enable these are each one or more piston / cylinder units 26 at or near their other end, as in 1 but possibly also in a central region thereof, with respect to the undercarriage base 14 supported. The piston / cylinder units are preferably designed to be double-acting and allow movement of the crawler track chassis units 18 with respect to the undercarriage base 14 under expansion or retraction of the same. Here, for example, for the two crawler chassis units 18 on both sides of the undercarriage base 14 provided piston / cylinder units 26 shorted with their respective cylinder chambers with respect to each other, so connected. This means that if one of the piston / cylinder units 26 the volume of a cylinder chamber is reduced, for example, because this crawler chassis unit is relative to the undercarriage base 14 lifts, pressurized fluid, so for example, oil, in a corresponding cylinder chamber or a balance memory of the other crawler chassis unit associated piston / cylinder unit 26 is encouraged to counteract this crawler chassis unit 18 to reach. Thus, a self-leveling of the two crawler tracks units becomes 18 achieved with the result that they not only punctually, for example, at respective end regions and lead there to a very strong pressure load of the soil, even on uneven terrain, but substantially flat or at least on several support areas on the ground and thus for a larger distribution the pressure load. It is of course also possible that the piston / cylinder units 26 be actively controlled, for example, the use of sensor signals from position sensors, which indicate that the excavator / working device 10 beyond a certain extent. Fed by a pressurized fluid source can then be the piston / cylinder units 26 for obtaining a counteracting the inclination or a uniform ground load inducing pivoting of the crawler track suspension units 18 be controlled.

As previously stated, is on the undercarriage 12 the superstructure 22 is rotatably supported about the substantially vertical axis of rotation D ₁ , preferably in a rotation angle range of 360 °. It can be seen that, contrary to the known in conventional excavators arrangement of the superstructure 22 not in the middle of the undercarriage 12 but in a first longitudinal region L _{1 of} the undercarriage 12 or undercarriage base 14 is arranged, which at a first end portion 28 of the undercarriage 12 lies. The first length region L ₁ is adjoined by a second length region L ₂ , which essentially extends to the other end region 30 the undercarriage base 14 extends and which is designed to receive an additional working device. To accommodate an additional implement L _{2 is} on the undercarriage base in the second length range 14 an accessory implement carrier arrangement 32 intended. In the example shown, this includes a platform 34 that have a turntable 36 on the undercarriage 12 or the undercarriage base 14 is rotatably supported about a second substantially vertical axis of rotation D ₂ . Through a turntable 36 associated drive to the undercarriage base 14 can the platform 34 preferably be rotated in a rotation angle range of 360 ° about the rotation axis D ₂ , which means that the platform 34 ultimately in any rotational angle positioning with respect to the undercarriage 12 can be positioned, for example, no rotation angle limiting in the form of a movement stop or the like is present.

In the illustrated configuration example, as an auxiliary implement on the accessory implement carrier assembly 32 a settling and tipping bridge 38 arranged. The settling and tipping bridge 38 is formed in the illustrated example as a trough for receiving tree trunks, soil, rock or the like. This dump-dumping bridge 38 extends substantially over the entire second length range L ₂ away and beyond and is substantially in its entire longitudinal extension of the track-mounted vehicle units 18 overlaps. This means that even when large loads are absorbed in the dumping tipping bridge 38 an even load on the subsoil over the additionally swingable crawler tracks 18 can be achieved.

Around the settling and tipping bridge 38 as additional working device on the undercarriage 12 to position or remove it and also a tilting movement of the settling and tipping bridge 38 For example, to obtain for unloading soil or other bulk material is at the additional implement carrier assembly 32 in a the end area 30 of the undercarriage 12 near area a generally with 40 designated roller assembly provided. This in the 2 Roller assembly shown in more detail 40 comprises two substantially conical rollers 42 . 44 , The role 42 is on a piston rod 46 a piston / cylinder unit 48 rotatably supported while the roller 44 on a cylinder 50 the piston / cylinder unit 48 about the same axis of rotation D ₃ as the role 42 is rotatably supported. The roles 42 . 44 act on the movement of the settling and tipping bridge 38 in the undercarriage longitudinal direction R with corresponding carriers or rails on the underside of the settling and tipping bridge 38 together to achieve a defined centering of the same. At the same time, the roller arrangement serves 40 to do so, on on the accessory implement carrier assembly 32 recorded settling and dumping bridge 38 to define their pivot axis. For this example, the cylinder 50 the piston / cylinder unit 48 at the platform 34 determined, z. B. welded or screwed. By extending the piston rod 46 can the two roles 42 . 44 in the direction of its axis of rotation D ₃ are moved away from each other. With appropriate retraction of the piston rod 46 the preferably double-acting piston / cylinder unit 48 become the roles 42 . 44 and thus also provided, facing each other clamping surfaces 52 . 54 moved towards each other. At the bottom of the dump-dumping bridge 38 For example, in the form of U-shaped rails provided abutment for the roles 42 . 44 or the clamping surfaces provided thereon 52 . 54 intended. To move the settling and dumping bridge 38 in the Undercarriage longitudinal direction R are the rollers 42 . 44 moved apart, so they are indeed a rolling or sliding support for the Absetz-tilting bridge 38 provide, but not hinder the shift. To enable tilting of the dump-dump bridge 38 be achieved as a pivot axis a clamping-holding effect about the axis of rotation D ₃ , so by appropriate control of the piston / cylinder unit 48 the roles 42 . 44 with their clamping surfaces 52 . 54 moved towards each other and thus the clamping surfaces 52 . 54 in contact with the at the dump-dumping bridge 38 provided abutments pressed. As in this state, the roles 42 . 44 basically on the piston rod 46 or the cylinder 50 can be rotated about the rotation axis D ₃ , the rollers 42 . 44 together with the attached dump-dumping bridge 38 be pivoted about the axis of rotation D ₃ , as indicated by an arrow P ₂ in the 1 indicated, a corresponding pivoting of the settling and tipping bridge 38 to achieve emptying at a defined pivot axis.

Around the settling and tipping bridge 38 on the undercarriage 12 To arrange or move, is on the excavator / working device 10 one in the form of an excavator arm 56 trained movement drive 58 intended. The one on the superstructure 22 provided excavator arm 56 , in the example shown with one on the superstructure 22 directly pivotally supported first arm member 60 and one at the free end of the first arm member 60 preferably via a quick coupling 62 pivotally supported second arm member 64 is formed, can be used to any movement of the settling and tipping bridge 38 trigger. For this purpose, with the free end of the second arm member 64 , on which, for example, also a quick coupling 66 may be provided, for example, with a hook provided there on a corresponding engagement formation on the Absetz-tilting bridge 38 be attacked and this raised or on the roller assembly 40 moved or pivoted with this about the rotational or pivot axis D ₃ . This can be done by the platform 34 for example, be oriented so that they and thus also the settling tipping bridge 38 is aligned in the undercarriage longitudinal direction R. The settling and tipping bridge 38 can thus towards the end area 30 of the undercarriage 12 be tilted or over this end 30 be picked up or unloaded. With appropriate rotation of the platform 34 However, about the axis of rotation D ₂ can also be tilted to the side or the Absetz-tilting bridge 38 be dropped off to the side or possibly from the side on the additional implement carrier assembly 32 be recorded.

In the receiving state of the settling and dumping bridge 38 this in addition by the generated by weight friction friction on the undercarriage 12 or the platform 34 To lock, can be an intervention formation 68 be provided, which one the Absetz-tilting bridge 38 against displacement on the platform 34 or the accessory implement carrier assembly 32 locking positive engagement produced by interlocking corresponding stop elements. This procedure can be easily achieved by using the excavator arm 56 when lifting the dumping / tipping bridge 38 be solved. Further locking mechanisms for the settling and tipping bridge 38 are then not required, but can of course be provided.

To the suitability or flexibility of the excavator / work device 10 To further increase, at this additional equipment can be added 84 be provided. Thus, at one, in the example shown at both end regions 28 . 30 of the undercarriage 12 on the undercarriage base 14 pivotally mounted grading or clearing blades 70 . 72 be provided. To move the same in the height direction piston / cylinder units 74 . 76 be used on the undercarriage base 14 on the one hand and z. B. one with the respective plow blade 70 . 72 on the other hand attack attacked assembly.

On one, but optionally also two Räumschilden 70 . 72 may be another additional subrack assembly 78 be provided. In this case this is at the end 30 of the undercarriage 12 , that is to say the clearing blade provided adjacent to the end region L ₂ 72 the case. This further additional subrack assembly 78 is via a joint arrangement on the plow blade 72 about a preferably horizontal pivot axis S ₃ pivotally supported. To adjust the pivot position serve one or more piston / cylinder units 80 working on the accessory tool carrier assembly 78 on the one hand and on the plow blade 72 or a carrier arrangement 82 the same attacks on the other hand. In the example shown, they are used to lift the plow blade 72 serving piston / cylinder units 76 at this with the carrier assembly 82 coupled piston / cylinder units 80 at.

At the additional accessory implement carrier arrangement 78 can be interchangeable additional equipment described below 84 be attached. In the example shown, this is one in the 6 illustrated clamping tank 86 , This can on the one hand together with the plow blade 72 On the other hand, however, by using the piston / cylinder units can be moved up and down 80 also regarding the plow blade 72 be pivoted. The clamping bench 86 comprises two or possibly more on a carrier 88 swiveling clamping arms 90 . 92 , which basically in the open state, an upwardly open receiving space 94 limit. With open clamp arms 90 . 92 is it even if such a clamping bench 86 on the plow blade 72 is possible, possible, the settling tipping bridge 38 towards the end area 30 over the plow blade 72 to settle or absorb. The carrier 88 the clamping bench 86 may be at the accessory implement carrier assembly 78 be locked for example by a quick release arrangement, wherein preferably the carrier 88 then with respect to the accessory implement carrier assembly 78 is rotatable. Such a clamping bench 86 Can be used to long items, such. As felled trees or pipes, using the excavator 56 in the recording room 94 to pick up and clamp and then use the excavator / work implement 10 pulling to transport.

Picking up or removing the settling and dumping bridge 38 on the base of the undercarriage 12 provided additional implement carrier arrangement 32 over the plow blade 72 It can also be relieved or supported by the fact that on the dozer blade 72 , preferably the auxiliary implement carrier arrangement 78 , another role arrangement 96 is provided. This can be compared to that described above with reference to FIGS 2 described roller assembly 40 be identical in order to also in this area, so on the plow blade 72 , by the possibility of the settling tipping bridge 38 between the rollers of the roller assembly 96 to pinch, a tilting of the settling tipping bridge 38 to allow a rotation axis D _{4 of} these roles. It is still possible, on the one hand by raising or lowering the dozer blade 72 and on the other hand by pivoting the additional implement carrier assembly 78 who also have this role arrangement 96 carries, the spatial position of this pivot axis D ₄ and thus the height of the settling and tipping bridge 38 when tilting or the proximity of the pivot axis D ₄ to the undercarriage base 14 adjust. This can in particular also contribute to the process of settling or picking up the settling and tipping bridge 38 by setting a slightly closer to the ground as the axis of rotation D ₃ positioned axis of rotation D ₄ easier.

It should be noted that such an accessory tool carrier assembly 78 like you on the snowplow 72 is provided, also or alternatively at the end 28 of the undercarriage 12 provided clearing blade 70 can be arranged.

Through a smoothing arrangement 316 For example, provided by a plurality of chain link-like elements, which stroke the ground during the previous movement, the previously loosened ground is again smoothed or a leveling achieved.

At the excavator / working device 10 Of course, in addition to the numerous previously described additional working implements, additional additional working tools can also be used as an alternative or in addition. For example, instead of the settling and dumping bridge 38 arranged as an additional working device a metering device having a storage container for metered material to be dispensed, generally provided in particle form or powder form, as well as a this well from the container receiving scattering or dosing. With such an arrangement, powdered or particulate materials such. As minerals or road salt or the like, are delivered. Again, the drive through the excavator / working device 10 provided pressurized fluid. In particular, it is thus possible, for example, before carrying out processing operations in the landscape to first scatter minerals, which provide for completion of the work for the fastest possible recovery of the soil. Such a metering device could alternatively also as an additional working device in the on the undercarriage 12 provided settling and dumping bridge 38 be positioned.

Furthermore, it is possible to provide a spreading device as an additional working device, for example on the second additional implement carrier arrangement 78 to distribute powdery or grain-like spreading material on the ground. This can, for example, in the settling and tipping bridge 38 be contained and are discharged by tilting the same in a receiving opening of the spreader. It is also possible, such grit from one in place of the settling and tipping bridge 38 on the first accessory implement carrier assembly 32 to record positioned storage container.

It should be noted that various aspects of the excavator / work device according to the invention 10 can be implemented in a modified manner or additional aspects can be provided. So it is possible, for example, that the excavator / working device 10 by a driver from a cabin 270 is controlled out. In particular, however, if the view of the area to be processed is impaired, it is possible by a remote control device, the required drive commands also from a position outside of the excavator / work device 10 to give. Furthermore, it is of course possible that the settling and dumping bridge 38 designed for other purposes in a different way. In particular, this can also be carried out container-like, so also completed at the top. At the excavator arm 56 can as an additional working device 84 also a bucket, z. As backhoe, are provided.
