Description
Selbstfahrende Vorrichtung zum Anheben und Versetzen von Hebegut Die Erfindung betrifft eine selbstfahrende Vorrichtung mit einem Fahrgestell und einem an wenigstens einem verstellbaren Ausleger befestigten Saugheber zum Anheben und Versetzen von Hebegut, insbesondere zum Verlegen von handelsüblichen Beton-, Klinker- und Naturpflastersteinen, wobei der Saugheber rechteckig ist, als Faltenbalg ausgebildete, voneinander unabhängig winkel- und axialbewegliche Saugstempel und an allen Seiten gegen das Hebegut schwenkbare Richtbacken aufweist, dessen Saugstrom für alle Saugstempel beim Absetzen des Hebegutes durch ein zwischen der Vakuumpumpe und einem Vakuumtragsammler vorgesehenes Unterbrechungsventil unterbrochen werden kann nach Patent. (Patentanmeldung P 33 24 441.3).Self-propelled device for lifting and moving items to be lifted Die The invention relates to a self-propelled device with a chassis and a at least one adjustable boom attached suction lifter for lifting and Moving items to be lifted, especially for laying conventional concrete, clinker and natural paving stones, whereby the suction lifter is rectangular, designed as bellows, Independently angular and axially movable suction pads and on all sides has swiveling straightening jaws against the item to be lifted, the suction flow of which for all suction rams when setting down the material to be lifted through a between the vacuum pump and a vacuum pick-up provided interrupt valve can be interrupted according to patent. (Patent application P 33 24 441.3).
Mit dem eingangs genannten Saugheber ist es möglich, Teile mit hohen spezifischen Gewichten, beispielsweise Betonstei ne, Klinker und dergleichen zu heben und zu versetzen. Dabei ist es möglich, eine Anzahl von Teilen, die bereits in einem Verlegemuster angeordnet sind zu erfassen und ohne Verschiebung gegeneinander unter Beibehaltung des Musters zu verlegen Das erfordert eine genügend hohe Tragkraft, die jedoch nur dann sichergestellt ist, wenn das Vakuum unter den einzelnen Saugstempeln genügend hoch ist Es hat sich jedoch gezeigt, daß das Material von Betonteilen nicht immer die genügende Dichte aufweist so daß das Steingefüge porös ist und Luft in erheblichem Maße durchläßt. Besonders schlecht abbindendes Betonmaterial führt zu porösem Steingefüge, das dann die Ausbildung eines genügenden Vakuums verhindert Betonhersieller sind jedoch nicht immer in der Lage, derartige Mängel zu beheben, da das Abbinden der Betonteile von der Feuchtigkeit der Umgebungsluft in erheblichen Maße beeinflußt wird Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit einem Saugheber der eingangs genannten Art so aLlsmugestalten, daß Teile aus Beton mit einem porösen Gefüge ohne Erhöhung der Saugleistung erfaßt und gehoben werden können. Die erfindungsgemäße Lösung zeichnet sich dadurch aus, daß die Saugöffnungen benachbarter Saugstempel in einen auf die Oberfläche des zu hebenden Gutes setzbaren Saugraum mit gemeinsam wirkender Saugfläche münden. Hierdurch wird erreicht, daß der Raum zwischen den einzelnen Saugstempeln erfaßt und in die jeweils wirksamen Saugräume der Saugstempel mit einbezsgen werden können und dadurch die Saugkraft ohne Erhöhung der Saugleistung der Vakuumpumpen vergrößert wird. Die Verbindung wenigstens zweier benachbarter Saugstempel durch einen Saugschuh mit gemeinsamen Saugraum reicht aus, um beispielsweise die bisher von zwei Saugstempeln erfaßten jedoch nicht anhebbaren Betonteile poröser Struktur heben zu können.With the suction lifter mentioned above, it is possible to remove parts with high specific weights, for example concrete stones, clinker and the like lift and move. It is possible to have a number of parts that are already are arranged in a laying pattern to be detected and without shifting against each other to be laid while maintaining the pattern This requires a sufficiently high load-bearing capacity However, this is only ensured if the vacuum is under the individual suction pads It has been shown, however, that the material of concrete parts is not high enough always has sufficient density so that the stone structure is porous and air in to a considerable extent. Particularly bad setting Concrete material leads to a porous stone structure, which then prevents the formation of a sufficient vacuum However, concrete predictors are not always able to remedy such deficiencies, because the setting of the concrete parts from the humidity of the ambient air in considerable Dimensions is influenced The invention is based on the object of a device with a suction lifter of the type mentioned at the outset in such a way that parts are made of Concrete with a porous structure captured and lifted without increasing the suction power can be. The solution according to the invention is characterized in that the suction openings Adjacent suction ram that can be placed on the surface of the item to be lifted Open into the suction chamber with a jointly acting suction surface. This achieves that the space between the individual suction plungers is recorded and the respectively effective one Suction spaces of the suction stamp can be included and thereby the suction force is increased without increasing the suction power of the vacuum pumps. The connection at least two adjacent suction rams through a suction shoe with common Suction space is sufficient to, for example, the previously detected by two suction plungers but not to be able to lift concrete parts of porous structure.
Besonders günstig hat sich die Anordnung von Verbindungsöffnungen zwischen dem Saugraum und den Saugstempeln durch Luftdurchtrittsöffnungen erwiesen, deren Durchmesser wesentlich kleiner als die Durchmesser der Anschlußstutzen für die Saugstempel gehalten ist Sofern die Luftdurchtrittsöffnungen so nahe an die Oberfläche des zu hebenden Gutes herangeführt werden daß diese in den unmittelbaren Bereich erhöhter Strömungsgeschwindigkeit beim Durchtritt der Luft gelangen, wird die Tragfähigkeit bei porösem Steinmaterial weiter erhöht.The arrangement of connection openings has proven to be particularly favorable proven between the suction space and the suction pads through air passage openings, whose diameter is much smaller than the diameter of the connecting piece for the suction pad is held provided the air passage openings so close to the Surface of the goods to be lifted are brought up so that they are in the immediate Area of increased flow velocity when the air passes through it will come the load-bearing capacity of porous stone material is further increased.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt und nachstehend erläutert Es zeigen: Fig. 1 die Seitenansicht eines Saugschuhes zum Teil im Schnitt und Fig. 2 die Draufsicht auf den Saugschuh gemäß Figur 1 Der Saugschuh 1 besteht aus einer Platte 2, deren Unterseite eine flächige Vertiefung 3 zur Bildung eines Saugraumes aufweist. Die Vertiefung 3 wird durch den durchgehenden Absatz 4 der Platte 2 gebildet. Über Durchtrittsöffnungen 5 ist die Vertiefung mit den Saugstempeln 6 verbunden. Zur Befestigung der Saugstempel am Saugschuh dienen Anschlußstutzen 7, die mit Umlaufnuten 8 versehen sind, um die formschlüssige Verbindung mit dem faltenbalgförmigen Saugstempel zu ermöglichen. An der Unterseite des Saugschuhes ist ferner eine Nut 9 zur Aufnahme einer Dichtlippe 10 aus elastomerem weichen Material vorgesehen Der Hohlraum 3 in Verbindung mit der Dichtlippe 10 bildet den gesamten Saugraum des Saugschuhes.An exemplary embodiment of the invention is shown schematically in the drawing shown and explained below 1 shows the side view of a suction shoe, partly in section, and FIG. 2 is a plan view of the suction shoe according to Figure 1 The suction shoe 1 consists of a plate 2, the bottom of which is a has flat recess 3 to form a suction space. The recess 3 will formed by the continuous paragraph 4 of the plate 2. Via openings 5, the recess is connected to the suction plungers 6. For attaching the suction pad on the suction shoe are connecting pieces 7, which are provided with circumferential grooves 8 to the To enable positive connection with the bellows-shaped suction ram. On the underside of the suction shoe there is also a groove 9 for receiving a sealing lip 10 made of elastomeric soft material. The cavity 3 in connection with the sealing lip 10 forms the entire suction space of the suction shoe.
Durch Anschrägungen 11 wird eine düSenähnliche Gestaltung der Durchtrittsöffnungen 5 erreicht, in deren Wirkungsbereich eine zusätzliche Druckabsenkung mit einer Erhöhung der Tragkraft erreicht wird Aus der Gesamtdarstellung ist leicht erkennbar, daß der Zwischenraum zwischen zwei Saugstempeln fast vollständig in die Saugwirkung mit einbezogen und die wirksame Saugfläche erheblich vergrößert wird, ohne die Vakuumleistung der Saugpumpen erhöhen zu müssen.Bevels 11 create a nozzle-like design of the passage openings 5 reached, in whose area of action an additional pressure reduction with an increase the load capacity is achieved From the overall view it is easy to see that the space between two suction pads is almost completely absorbed by the suction effect is included and the effective suction area is increased considerably, without the vacuum performance to have to increase the suction pumps.
