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.The invention relates to a suction excavator for targeted Picking up suction material, especially for lifting Soil on buried lines, with a pneumatic Suction nozzle for picking up the suction material, on the a suction port is arranged at the lower end and the its opposite end in a sump flows.

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 lines laid in the ground, the Pipeline construction often uses conventional shovel excavators, which are particularly disadvantageous, when it comes to a specific location on the buried To expose pipelines, for example Fix pipe breaks, connect branch lines or just to inspect the lines. Due to the Operation of a shovel excavator must be in the ground removed a large area and the overburden on the Construction site. Because of the relatively rough Operation and poor controllability of the bucket there is a significant risk of damage to the uncovered or adjacent lines. At media-carrying lines such as gas, water or waste water pipelines this can lead to the leakage of the medium electrical cables to destroy them.

Um die genannten Nachteile zu vermeiden sind zum gezielten Aufnehmen von Sauggut sogenannte Saugbagger entwickelt 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 disadvantages mentioned are targeted Picking up suction material developed so-called suction dredger have been using a blower Generates negative pressure and the suction material via a suction nozzle, that hangs on a boom and is adjustable in all directions is sucked into a collection container can. There the suction material is separated from the suction air flow, while still present in the transport air Dust or other particles must be filtered out before the transport air at the outlet side of the fan 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 excavator when used for excavation work to a high degree from is dependent on 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 proboscis Suction port in the stroke frequency, i.e. the number of strokes per Minute, and the dwell time on the ground, i.e. the real one Suction time, both depending on the material to be recorded are different, the consistency of each to be absorbed Material can be adjusted. The operator is mostly overwhelmed because they are next to the controller the vertical up and down movement of the suction nozzle must also pay attention to where the Suction port expediently during the downward movement 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 has for its object a suction dredger for targeted absorption of suction material, in particular for Digging soil to create the handling the suction port is simplified for the operator.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Saugstutzen einen am Saugrüssel angebrachten Führungskörper und ein relativ zu diesem axial verfahrbares Saugmundstück aufweist, das mittels einer Antriebsvorrichtung in den Führungskörper einziehbar sowie aus diesem ausfahrbar ist.This object is achieved in that the suction nozzle a guide body attached to the proboscis and an axially movable relative to this Has suction mouthpiece that by means of a drive device retractable into and out of the guide body this is extendable.

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, the vertical is up and down Movement of the suction nozzle automated, so that the operator on the point of attachment of the suction mouthpiece can concentrate on the ground, making 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, its Stroke length and also its impact energy on the ground changeable and in particular adjustable by the operator is to adapt well to the respective, to reach the materials available on site. This can in particular by a programmable or programmed Control can be achieved, being for different Soil types the optimal parameter configuration for the stroke frequency, stroke length and impact energy of the suction mouthpiece in a memory already can be held so that the operator appropriate floor type only on a control panel must select using 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 in its axial movement led to the guide body on this, for what in known Way guide rings or strips can be 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, which preferably as a more spatial surrounding the guide body Handle frame is formed, which on the one hand Handle is given a high spatial stability and it on the other hand as an outer protective cage for the most If necessary, attach the guide body on the outside Additional devices, 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 ground there is a risk of being mistaken Live cables exposed and damaged will. To the operator in this case of electrical Protecting electric shocks is a further development of Invention provided that the guide body and / or that Handle is 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 a piston-cylinder unit has proven its worth either a compressed air or a hydraulic cylinder can act. To the piston-cylinder unit in front of outer unwanted burdens and especially dirt to protect them with a protective cover be surrounded. The impact energy of the suction mouthpiece to change on the ground are the piston-cylinder unit one or more adjustable pressure boosters assigned, depending on the materials to be absorbed can be optionally switched on or 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.A sensor device can be provided on the suction mouthpiece be, by means of which the depth of penetration of the suction mouthpiece in the soil to be recorded. The Sensor device gives a corresponding intrusion signal to the control device. If the control device determines that the depth of penetration is too small and thus the Soil is too hard, it switches automatically the pressure booster or gives the operator of the An optical and / or acoustic signal, so that it switches on the pressure booster 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 points at the bottom, into the ground engaging end in a known manner a toothing to loosen the soil. However, if the There is a risk that exposed soil suction Cables could be damaged, the teeth of the suction mouthpiece are covered with a cap, which is preferably pivotable or removable on the suction mouthpiece is appropriate.
