Abstract
Description
Die Erfindung betrifft einen Saugbagger zum gezielten Aufnehmen von Sauggut, insbesondere zum Ausheben von Erdreich an erdverlegten Leitungen, mit einem pneumatischen Saugrüssel zum Aufnehmen des Saugguts, an dessen unterem Ende ein Saugstutzen angeordnet ist und der an seinem entgegengesetzten Ende in einem Sammelbehälter mündet. US-A- 3 930 324, US-A- 4 936 031 sowie US-A- 5 487 229 offenbaren solche Saugbagger.The invention relates to a suction dredger for targeted Picking up suction material, especially for lifting Soil on buried pipelines, with a pneumatic Suction nozzle for picking up the suction material, at the lower end of a suction nozzle is arranged and the its opposite end in a sump empties. US-A-3,930,324, US-A-4,936,031 and US-A-5,487,229 reveal such suction dredger.
Bei Arbeiten an im Erdreich verlegten Leitungen werden im Rohrleitungsbau häufig herkömmliche Schaufelbagger eingesetzt, die jedoch insbesondere dann von Nachteil sind, wenn es darum geht, eine bestimmte Stelle an den erdverlegten Rohrleitungen freizulegen, um beispielsweise Rohrbrüche zu beheben, Abzweigleitungen anzuschließen oder die Leitungen nur zu inspizieren. Aufgrund der Arbeitsweise eines Schaufelbaggers muß das Erdreich in einem großen Bereich abgetragen und der Abraum an der Baustelle abgelegt werden. Aufgrund der relativ groben Arbeitweise und schlechten Steuerbarkeit der Schaufel besteht eine erhebliche Gefahr einer Beschädigung der freizulegenden oder davon benachbarter Leitungen. Bei medienführenden Leitungen wie Gas- Wasser- oder Abwasserrohrleitungen kann dies zum Austreten des Mediums, bei elektrischen Kabeln zu deren Zerstörung führen.When working on pipes laid in the ground, the Pipeline construction often used conventional excavators, which, however, are particularly disadvantageous when it comes to a particular spot on the underground Uncover pipelines, for example Repair pipe breaks, connect branch pipes or to inspect the lines only. Due to the Operation of a shovel must the soil in a large area and the overburden at the Construction site to be filed. Because of the relatively rough Working method and poor controllability of the shovel there is a significant risk of damage to the to be cleared or adjacent lines. at media-carrying lines such as gas water or sewage pipelines This may contribute to the leakage of the medium electrical cables lead to their destruction.
Um die genannten Nachteile zu vermeiden sind zum gezielten Aufnehmen von Sauggut sogenannte Saugbagger entwikkelt worden, bei denen mit Hilfe eines Gebläses ein Unterdruck erzeugt und das Sauggut über einen Saugrüssel, der an einem Ausleger hängt und in alle Richtungen verstellbar ist, in einen Sammelbehälter gesaugt werden kann. Dort wird das Sauggut aus dem Saugluftstrom abgeschieden, während noch in der Transportluft vorhandener Staub oder sonstige Teilchen ausgefiltert werden, bevor die Transportluft an der Austrittseite des Gebläses abgeblasen wird.To avoid the mentioned disadvantages are targeted Picking up suction material called suction dredger develops in which with the help of a blower a Creates negative pressure and the suction material via a proboscis, which hangs from a boom and can be adjusted in all directions is to be sucked into a collection container can. There, the suction material is separated from the suction air stream, while still present in the transport air Dust or other particles are filtered out before the transport air at the outlet side of the blower is blown off.
Es hat sich gezeigt, daß die Saugleistung eines Saugbaggers beim Einsatz für Erdaushubarbeiten in hohem Maße von der Geschicklichkeit der Bedienperson abhängig ist. Eine hohe Saugleistung wird erreicht, wenn die Hubbewegung des am freien, unteren Ende des Saugrüssels angeordneten Saugstutzens in der Hubfrequenz, d.h. der Hubzahl pro Minute, und der Verweilzeit am Boden, d.h. der eigentlichen Saugzeit, die beide je nach aufzunehmendem Material unterschiedlich sind, der Konsistenz des jeweils aufzusaugenden Materials angepaßt werden. Die Bedienperson ist dabei meistens überfordert, weil sie neben der Steuerung der vertikal auf- und abgerichteten Bewegung des Saugstutzen auch darauf achten muß, an welcher Stelle der Saugstutzen bei der Abwärtsbewegung zweckmäßigerweise auf das Erdreich aufgesetzt werden muß.It has been shown that the suction power of a suction dredger when used for excavation to a high degree of the skill of the operator. A high suction power is achieved when the lifting movement of the arranged at the free, lower end of the suction pipe Saugstutzens in the stroke frequency, i. the number of strokes per Minute, and the residence time on the ground, i. the actual Suction time, both depending on the material to be recorded are different, the consistency of the aufzusaugenden each Material adapted. The operator is usually overwhelmed because they are next to the controller the vertically up and down movement of the suction nozzle must also pay attention to where the Suction on the downward movement expediently the soil must be put on.
Der Erfindung liegt die Aufgabe zugrunde, einen Saugbagger zum gezielten Aufnehmen von Sauggut, insbesondere zum Ausheben von Erdreich zu schaffen, bei dem die Handhabung des Saugstutzen für die Bedienperson vereinfacht ist.The invention is based on the object, a suction dredger for targeted picking up of suction material, in particular for Excavation of soil to create in which the handling the suction nozzle for the operator is simplified.
Im Oberbegriff des Anspruchs 1 wird von einem
Saugbagger ausgegangen, wie er in der
US-A- 3 930 324 gezeigt ist.In the preamble of
Die Aufgabe wird erfindungsgemäß
durch einen Saugbagger mit den
kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the invention
through a suction dredger with the
characterizing features of
Erfindungsgemäß ist somit die vertikale auf- und abgerichtete Bewegung des Saugstutzen automatisiert, so daß sich die Bedienperson auf den Aufsetzpunkt des Saugmundstücks auf dem Erdreich konzentrieren kann, wodurch die Betätigung des Saugbaggers wesentlich erleichtert wird und gleichzeitig eine hohe Saugleistung zu erzielen ist.According to the invention is thus the vertical up and trained Automated movement of the suction nozzle, so that the operator on the Aufsetzpunkt the suction mouthpiece can concentrate on the soil, causing the Operation of the suction dredger is much easier and at the same time a high suction power can be achieved.
Die Bewegung des Saugmundstücks relativ zum Führungskörper kann kontinuierlich oder intermittierend sein. Vorzugsweise ist jedoch vorgesehen, daß die Hubfrequenz, d.h. die Hubzahl des Saugmundstücks pro Minute, seine Hublänge und auch seine Aufschlagenergie auf dem Erdreich veränderbar und insbesondere von der Bedienperson einstellbar ist, um eine gute Anpassung an die jeweiligen, am Einsatzort vorhandenen Materialien zu erreichen. Dies kann insbesondere durch eine programmierbare oder programmierte Steuerung erreicht werden, wobei für verschiedene Bodenarten die jeweils optimale Parameterkonfiguration für die Hubfrequenz, die Hublänge und die Aufschlagenergie des Saugmundstücks in einem Speicher bereits vorgehalten werden kann, so daß die Bedienperson die entsprechende Bodenart lediglich auf einem Bedienpult mittels eines Wahlschalters auswählen muß. The movement of the suction mouthpiece relative to the guide body can be continuous or intermittent. Preferably However, it is provided that the stroke frequency, i.e. the number of strokes of the suction mouthpiece per minute, his Stroke length and also its impact energy on the ground changeable and adjustable in particular by the operator is to adapt well to the respective, to reach existing materials at the site. This in particular by a programmable or programmed Control can be achieved, taking for different Soil types each the optimal parameter configuration for the stroke frequency, the stroke length and the impact energy the suction mouthpiece in a store already can be held, so that the operator corresponding soil type only on a control panel must select by means of a selector switch.
Das Saugmundstück ist bei seiner axialen Bewegung relativ zu dem Führungskörper an diesem geführt, wozu in bekannter Weise Führungsringe oder -leisten vorgesehen sein können.The suction mouthpiece is relative to its axial movement led to the guide body on this, including in known Way guide rings or strips provided can.
Um der Bedienperson die Handhabung des Führungskörpers zu erleichtern, besitzt dieser ein Griffstück, das vorzugsweise als ein den Führungskörper umgebener, räumlicher Griffrahmen ausgebildet ist, wodurch einerseits dem Griffstück eine hohe räumliche Stabilität verliehen ist und es andererseits als äußerer Schutzkäfig für die am Führungskörper gegebenenfalls außenseitig angebrachten Zusatzeinrichtungen, z.B. Hydraulikleitungen, Antriebseinrichtungen etc., dient.To the operator to handle the guide body facilitate, this has a handle, preferably as a space surrounded by the leadership body Handle frame is formed, whereby on the one hand the Handle is given a high spatial stability and on the other hand, as an outer protective cage for the am Guide body optionally mounted on the outside Ancillary equipment, e.g. Hydraulic lines, drive devices etc., serves.
Beim Arbeiten im Erdreich besteht die Gefahr, daß irrtümlicherweise stromführende Kabel freigelegt und beschädigt werden. Um die Bedienperson in diesem Fall von elektrischen Stromschlägen zu schützen, ist in Weiterbildung der Erfindung vorgesehen, daß der Führungskörper und/oder das Griffstück gegenüber dem Saugmundstück elektrisch isoliert ist.When working in the soil there is a risk that erroneously live cables exposed and damaged become. To the operator in this case of electrical To protect electric shocks is in the further education of the Invention provided that the guide body and / or the Handle electrically insulated from the suction mouthpiece is.
Als Antriebsvorrichtung für das Saugmundstück hat sich eine Kolben-Zylinder-Einheit bewährt, wobei es sich entweder um einen Preßluft- oder einen Hydraulikzylinder handeln kann. Um die Kolben-Zylinder-Einheit vor äußeren ungewollten Belastungen sowie insbesondere vor Verschmutzungen zu schützen, kann sie mit einer Schutzabdeckung umgeben sein. Um die Aufschlagenergie des Saugmundstücks auf dem Erdboden zu verändern, sind der Kolben-Zylinder-Einheit ein oder mehrere einstellbare Druckverstärker zugeordnet, die je nach den aufzusaugenden Materialien wahlweise zuschaltbar oder abschaltbar sind.As a drive device for the suction mouthpiece has a piston-cylinder unit proven, it is either a compressed air or a hydraulic cylinder can act. To the piston-cylinder unit from outside unwanted loads and especially against soiling It can be protected with a protective cover be surrounded. To the impact energy of the suction mouthpiece to change the ground are the piston-cylinder unit one or more adjustable pressure intensifiers depending on the materials to be absorbed optionally switchable or can be switched off.
An dem Saugmundstück kann eine Sensorvorrichtung vorgesehen sein, mittels der die Eindringtiefe des Saugmundstücks in das aufzunehmende Erdreich erfaßt wird. Die Sensorvorrichtung gibt ein entsprechendes Eindring-Signal an die Steuervorrichtung ab. Wenn die Steuervorrichtung feststellt, daß die Eindringtiefe zu gering und somit das Erdreich zu hart ist, schaltet sie entweder selbsttätig den Druckverstärker zu oder gibt der Bedienperson des Saugstutzens ein optisches und/oder akustisches Signal, damit diese den Druckverstärker manuell zuschaltet.At the suction mouthpiece, a sensor device may be provided be, by means of the penetration depth of the suction mouthpiece is detected in the recorded soil. The Sensor device gives a corresponding intrusion signal to the control device. When the control device determines that the penetration depth is too low and thus the Soil is too hard, it switches either automatically the pressure intensifier or gives the operator of the Saugstutzens an optical and / or acoustic signal, so that it connects the pressure intensifier manually.
Das Saugmundstück weist an seinem unteren, in das Erdreich eingreifenden Ende in bekannter Weise eine Verzahnung zur Lockerung des Erdreichs auf. Falls jedoch die Gefahr besteht, daß beim Saugen des Erdreichs offenliegende Kabel beschädigt werden könnten, kann die Verzahnung des Saugmundstücks mit einer Kappe abgedeckt werden, die vorzugsweise schwenkbar oder abnehmbar am Saugmundstück angebracht ist.The suction mouthpiece has at its lower, in the soil engaging end in a known manner a toothing to loosen the soil. However, if the There is a risk that when sucking the soil exposed Cables could be damaged, the gearing may the suction mouthpiece are capped, preferably pivotally or detachably on the suction mouthpiece is appropriate.
