Abstract

The invention relates to a work equipment for a hydraulic universal excavator. It is used for removing and picking up old floors in sidewalk, road and motorway construction. The tip of the jib forms a bifurcation connected by a stiffener. At the stiffening a bearing block is geschweiszt, which has a point of articulation for the Loeffelstielzylinder. Trained as Klassierschaufel grave Gefaesz can be used to break loose and picking up old blankets. The Umruestaufwand is low. The Loeffelkippzylinder is attached to the bearing block and at the front articulation point of the classifying bucket and ensures a Geradfuehrung the Klassierschaufel.

Description

Field of application of the invention

The working equipment is used for removing and receiving ^Λ ltdecken in the walkway, road and highway construction.

Characteristic of the known state of the art

There are foreclosures of the grave vessel for bucket and bucket equipment known in which the linear guides is done by computer-controlled cylinder.

Furthermore, parallel guides of the grave vessel are known, which are achieved by one or more parallelograms, which are interconnected.

The equipments are very expensive to manufacture and to entertain because a large number of handlebars are required. The conversion of a standard equipment is very expensive. In the case of loading bucket equipment, the created planum must be driven through the excavator in the further course of the work and is thereby partially destroyed.

Object of the invention

The aim of the invention is to provide a cost-effective work equipment, which can be installed without major Umr expenditure on a standard · Tieflöffolausrüstung and with the existing Planum is not destroyed.

Explanation of the essence of the invention

It is an object of the invention to provide a working equipment, broken up with the old slabs in the renovation and reconstruction of sidewalks, roads and highways and can be included without destroying the lying under the old gravel bed.

The tip of the boom has a fork. The two fork parts are connected by a stiffener. At the stiffening a bearing block is attached, which has a Anlonkpunkt for the arm of the dipper stick.

If trained as Klassierschaufel grave vessel operated as backhoe, then the arm is attached to the front pivot point of the grave vessel and the rear linkage the coupling is attached, which is about a rocker with the Löffelkippzylinder the verb, which is attached to sinem bearing block on the dipper stick is welded.

If the broken old blanket is to be taken without damaging the layer of gravel underneath the old blanket, then the bucket cylinder is fixed on the one hand to the bearing block of the boom and on the other hand to the front articulation point of the classifying bucket. The rear pivot point of the classifier bucket is attached to the dipper stick tip.

embodiment

The invention will be explained in more detail using an exemplary embodiment. In the accompanying drawing show

The equipment is used in the rehabilitation and reconstruction of sidewalks, roads and highways. The old blanket 25 is broken and picked up by means of the classifying blade 1 or otherwise. The hydraulic universal excavator 10 consists of superstructure 14, undercarriage 17 and shelter 16. In the bearing 18 of the superstructure 14 dor boom 5 is articulated, which is actuated by the boom cylinder 11. The boom cylinder 11 is fixed to the bearing block 19 of the upper carriage 14 and further on the bearing block 20 of the boom 5. The tip of the boom 5 forms a stiffener 21 with fork 22. The fork 22 is provided with a bearing 8 to which the arm 7 is hinged , The dipper stick 7 is driven by the dipper stick cylinder 9. On the dipper stick 7, a bearing block 23 is welded.

If the classifying blade 1 is to be operated like a backhoe, then it will be hinged to the bearing block 23 of the spoon-tilting cylinder 4, which actively activates the classifying blade 1 via a rocker 12 and via a coupling 13. The classifying blade 1 is attached to the articulation point 2 at the top of the Loil.ilstiols 7. At the stiffener 21 of the bearing block 6 is welded. If the broken old blanket 25 to be taken with the Klassierschaufol 1, then the spoiler cylinder 4 is dismantled from the bearing block 23. The rocker 12 and the coupling 13 have been removed. The Classifying scoop 1 is from the dipper stick?

dismantled and attached to the articulation point 3 on the dipper 7.

The different diameters of the bearings of the pivot points 2; 3 are balanced by jacks. The Löffelkippzylinder 4 is mounted with the foot at the pivot point 24 of the bearing block 6 and secured with the piston rod at the pivot point 2. The Löffelkippzylinder 4 acts as a passive coupling member and is only active for emptying the Klassierschaufel.

When extended on spoon rod length spoiler cylinder 4 form the connecting lines of the pivot points 2; 3; 24 and the bearing 8 a Paralielcgramm that results in moving the Klassierschaufel 1 by means of the arm cylinder 9, in the direction of the hydraulic universal excavator 10, a nearly rectilinear path. Weak curvatures of the web can be eliminated by minimal corrective movements by means of the boom cylinder.

The proposed kinematics, the inclusion of broken old blankets 25 takes place without destroying the gravel bed 15th

The universal excavator 10 stands on the old blanket 25 and can no longer destroy the existing plenum of the gravel bed 15 by driving movements. The gravel bed 15 can be reused without reworking.

Claims (1)
