Definitions
- the invention is directed to an excavator handling tool with a shovel, in particular with a backhoe, and a hydraulically operated gripping plate assigned to the shovel.
- the present invention is directed to a further development of an excavator shovel, in particular a deep-ice bucket.
- an operator of such an excavator e.g. to be able to reach with a shovel, for example in order to be able to transport large fragments, building pieces, larger wooden or reinforced concrete beams, etc. the like
- a spoon is known from SU-A-1 303 675 with two attachment gripping elements which are pivotally arranged thereon and can be moved via separate hydraulic drives.
- the excavator bucket is attached to the excavator boom in the usual way.
- DE-A-30 04 834 also shows an excavator bucket which is pivotably arranged on the excavator boom or excavator arm in a conventional manner, a counter-gripping element being articulated on the auxiliary hydraulic cylinder in such a way that the Swiveling the spoon in the closing direction, the counter element is also effected in the closing direction, the opening movement takes place in reverse.
- WO 89/12145 again shows a spoon articulated on two carrying arms on the excavator boom, the carrying discs having hydraulic cylinders with which gripping tines can be moved.
- the object of the invention is to provide a solution with which the mobility of the spoon is increased and at the same time the individual closing and opening of a gripping tool is made possible.
- a carrier pivot frame is provided on the gripping plate, in which the bucket is pivotally mounted, the carrier pivot frame itself being pivotally arranged on the arm of the excavator and effectively on the bucket cylinder.
- the gripping lath is connected to the cantilever arm or the arm of the excavator and the spoon itself is articulated on this plate, great mobility can be achieved over a wide swiveling range of the spoon.
- the blade on the carrier swivel frame can be moved via at least one piston / cylinder unit arranged on the carrier swivel frame, in particular in relation to the gripping plate in the open or closed position.
- the shovel or the gripper plate is provided with swivel arms on the upper back outer edge area, at the free end of which a hydraulic piston / cylinder unit engages, the other end of each piston / cylinder unit on the lower
- the outer edge area of the gripper plate or the bucket is articulated.
- An expedient embodiment of the excavator bucket consists in that the gripping plate is provided with two pairs of backing plates which accommodate the swivel fitting at the upper end and the fastening fitting for the piston / cylinder unit at the lower end and form part of the carrier swivel arm.
- Another possible embodiment of the invention consists in forming the gripping plate itself in the manner of a spoon.
- the invention also provides that the tool is provided with a rotating and / or swiveling device for rotating or swiveling the blade with a gripping plate in a plane deviating from the swiveling plane of the shovel or the gripper plate.
- FIG. 1 shows the simplified basic side view of an excavator with the handling tool according to the invention
- Fig. 6 shows a simplified spatial representation of the handling tool
- Fig. 7 is a side view of the carrier swivel frame according to the invention.
- the excavator generally designated 1, the specific design of which is not important here, has a working or basic boom 2, on which a dipper arm 3 is pivotally mounted via a hydraulic piston / cylinder unit 4.
- the dipper arm carries at its free end pivotally egg nen carrier swivel frame 5, the other pivot 6 is connected via a coupling piece 7 and a rocker 8 with a Löf fel cylinder 9 is effectively connected.
- a shovel 11 is arranged on the carrier and swivel frame via a swivel joint 10, which has a swivel arm 12 pointing beyond the swivel joint 10, on the free end 13 of which a further hydraulic piston / cylinder unit, called gripper cylinder 14 for short, engages.
- the gripper cylinder 14 is pivotally articulated at the lower end 15 of the back plate 16, the back plate 16 being elements of the support and swivel frame 5.
- the swivel frame 5 or the back web plates 16 carry a gripper plate 17, which in turn is at least partially spoon-like in the example shown.
- the mode of operation of the handling tool according to the invention results from an overview of FIGS. 2 to 4:
- the shovel is brought into the open position relative to the gripper plate 17, e.g. 1. If the object to be gripped lies in a plane below the excavator position, the dipper stick is pivoted with the aid of the hydraulic piston / cylinder unit, it being possible for example for the basic boom 2 to remain in the position assumed . If the scoop 11 and the gripper plate 17 are above the object to be gripped, indicated in FIG. 2 as a pipe 18, the gripper cylinder 14 is actuated in such a way that the scoop 11 moves onto the gripper plate 17 z. If desired, the closing position can also be supported or corrected with spoon cylinder 9.
- the hydraulic switching and control of the various working methods and working movements can be designed in such a way that all working movements are carried out separately or else in such a way that movements are superimposed.
- the independent movements be the gripper-typical working movement at a shorter distance from the pivot point on the swivel arm to the blade cutting edge, which leads to higher crushing and load capacities.
- Fig. 5 the bucket movement is shown, the respective pivot options are shown by means of double arrows 19 to 21 th
- the double arrow 21 shows in outline in which swivel range a spoon according to the prior art can move. Both the opening area and the closing area of the blade 11 with the device according to the invention can be clearly seen, as shown by the double arrows 19 and 20.
- FIG. 6 shows a simplified perspective view of the excavator handling tool with a view of the carrier swivel frame 5 with the piston / cylinder units 14 arranged there and the web plates 16 holding them at the articulation point 15, which part of the swivel frame 5 form. From FIG. 6 it can also be seen how the spoon or the scoop 11 with its swivel arms 12 is arranged on the swivel joint 10 of the swivel plates 16.
- FIGS. 6 and 7 For mounting on the excavator boom, two mounting plates 22 are shown in FIGS. 6 and 7. A quick connection can also be provided at this point.
- both the gripper plate 17 and the blade 11 can be provided with recesses pointing inwards, in order, for example, to round elements, such as pipes or beams, as is often the case when the corresponding device is used. easier to grip.
- the arrangement of the hydraulic piston / cylinder units 14 can also be reversed with an otherwise identical construction, i.e. these can be arranged on the back of the bucket, in which case the swivel arms 12 are then attached to the swivel frame 5.
