Description
Die Erfindung betrifft eine Tiefbaumaschine mit einem Unterwagen, welcher ein Fahrwerk umfasst, einem auf dem Unterwagen drehbar um eine vertikale Drehachse gelagerten Oberwagen, einem Mäkler mit einer Linearführung, entlang welcher ein Arbeitsschlitten mit einem Bauarbeitsgerät verfahrbar gelagert ist, und einem Anlenkmechanismus, mit welchem der Mäkler verstellbar an dem Oberwagen gelagert ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a civil engineering machine with an undercarriage, which comprises a chassis, an uppercarriage mounted on the undercarriage so that it can rotate about a vertical axis of rotation, a leader with a linear guide along which a working carriage with a construction equipment is mounted so that it can move, and a linkage mechanism with which the Leader is adjustably mounted on the superstructure, according to the preamble of claim 1.
Tiefbaumaschinen mit Mäklern sind hinlänglich bekannt und werden beispielsweise zum Erstellen von Bohrpfählen im Boden, Erdverankerungen oder zum Einbringen von Spundwandbohlen in einem Boden durch Einrütteln oder Einschlagen eingesetzt. Die Tiefbaumaschinen dienen insbesondere zum Ausführen von Gründungsmaßnahmen für Bauwerke oder entlang von Bauwerken.Civil engineering machines with leaders are well known and are used, for example, to create bored piles in the ground, ground anchors or to introduce sheet piling into a ground by shaking or hammering. The civil engineering machines are used in particular to carry out foundation measures for buildings or along buildings.
Ein Mäkler stellt einen im Wesentlichen vertikalen Mast dar, welcher an seiner Vorderseite mit einer Längsführung ausgebildet ist. Entlang der Längsführung ist ein Arbeitsschlitten mit einem Bauarbeitsgerät verschiebbar gelagert. Eine derartige Tiefbaumaschine mit einem Mäkler, wobei als Bauarbeitsgerät ein Rüttler vorgesehen ist, geht beispielsweise aus der
Der Mäkler ist mit einem mobilen Trägergerät über einen Anlenkmechanismus verbunden. In der
Dies kann durch eine Halteeinrichtung ausgeglichen werden, mit welcher der vertikale Mäkler vertikal verstellbar mit der Parallelogrammanordnung der Schwenkhebel verbunden ist.This can be compensated for by a holding device with which the vertical leader is connected to the parallelogram arrangement of the pivoted levers in a vertically adjustable manner.
In bestimmten Fällen ist es erforderlich, derartige Gründungsmaßnahmen in der Nähe oder entlang von Bahngleisen durchzuführen. Hierzu ist es beispielsweise aus der gattungsbildenden
Mit derartigen nachgerüsteten Tiefbaumaschinen können in der Regel nur relativ kurze Strecken auf Gleisen zurückgelegt werden. Zudem besteht aufgrund der relativ geringen Spurbreite auf Gleisen gegenüber einem normalen Rad- oder Raupenfahrwerk eine verringerte Kippsicherheit.With such retrofitted civil engineering machines only relatively short distances can be covered on tracks as a rule. In addition, due to the relatively small track width on rails, there is less security against tipping compared to a normal wheeled or caterpillar undercarriage.
Weiter ist es bekannt, eine bestehende Tiefbaumaschine mit einem Rad- oder Raupenfahrwerk insgesamt auf einem Eisenbahn-Transportwagen anzuordnen. Mit einem derartigen herkömmlichen Eisenbahnwagen kann grundsätzlich eine längere Strecke mit einer höheren Geschwindigkeit auf Gleisen zurückgelegt werden. Allerdings besteht bei solchen Anordnungen bei herkömmlichen Tiefbaumaschinen häufig das Problem, dass nur relativ kleine Tiefbaumaschinen eingesetzt werden können, um eine maximale Höhe, die durch Oberleitungen oder Bahntunnel vorgegeben ist, nicht zu überschreiten. Zudem wird durch die Anordnung einer herkömmlichen Tiefbaumaschine auf einem Eisenbahn-Transportwagen der Maschinenschwerpunkt über dem Boden erhöht, wodurch ebenfalls die Kippsicherheit reduziert wird. Dies hat dann eine entsprechende Beschränkung des Arbeitsbereiches und der Einsatzmöglichkeiten der Tiefbaumaschine zur Folge.It is also known to arrange an existing civil engineering machine with a wheeled or caterpillar undercarriage as a whole on a railway transport vehicle. In principle, a longer distance can be covered on rails at a higher speed with such a conventional railroad car. However, with such arrangements in conventional civil engineering machines, there is often the problem that only relatively small civil engineering machines can be used in order not to exceed a maximum height that is specified by overhead lines or railway tunnels. In addition, by arranging a conventional civil engineering machine on a railway transport wagon, the center of gravity of the machine is increased above the ground, which also reduces the stability against tipping. This then results in a corresponding restriction of the working area and the possible uses of the civil engineering machine.
Der Erfindung liegt die Aufgabe zugrunde, eine Tiefbaumaschine mit einem Mäkler anzugeben, mit welcher in besonders effizienter Weise Baumaßnahmen durchgeführt werden können.The invention is based on the object of specifying a civil engineering machine with a leader, with which construction measures can be carried out in a particularly efficient manner.
Die Aufgabe wird durch eine Tiefbaumaschine mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved by a civil engineering machine with the features of claim 1. Preferred embodiments of the invention are given in the dependent claims.
Die erfindungsgemäße Tiefbaumaschine ist dadurch gekennzeichnet, dass der Anlenkmechanismus einen Teleskoparm aufweist, mit welchem ein Abstand des Mäklers gegenüber dem Oberwagen verstellbar ist.The civil engineering machine according to the invention is characterized in that the linkage mechanism has a telescopic arm with which a distance between the leader and the superstructure can be adjusted.
Ein Grundgedanke der Erfindung besteht darin, bei einer Tiefbaumaschine mit einem Mäkler einen Anlenkmechanismus mit einem Teleskoparm einzusetzen, wobei der Teleskoparm im Wesentlichen horizontal gerichtet ist. Somit kann durch ein Ein- oder Austeleskopieren des Teleskoparms ein Abstand des Mäklers gegenüber dem Oberwagen und damit dem Trägergerät verändert werden. Durch Verwendung eines längenveränderlichen Teleskoparms kann insbesondere eine Parallelogrammanordnung mit Schwenkhebeln ersetzt werden.A basic idea of the invention is to use a linkage mechanism with a telescopic arm in a civil engineering machine with a leader, with the telescopic arm being directed essentially horizontally. Thus, by telescoping the telescopic arm in or out, the distance between the leader and the superstructure and thus the carrier device can be changed. In particular, a parallelogram arrangement with pivoting levers can be replaced by using a telescopic arm that is variable in length.
Außerdem erlaubt ein in der Länge veränderbarer Teleskoparm eine Abstandsänderung des Mäklers ohne wesentliche Änderungen auf die vertikale Lage des Mäklers. Weiter kann der Anlenkmechanismus einfach und kompakt ausgebildet werden. Hierdurch ergibt sich auch eine besonders kompakte Ausgestaltung der Tiefbaumaschine insgesamt, insbesondere mit einer relativ geringen Bauhöhe von Oberwagen und Anlenkmechanismus.In addition, a telescopic arm that can be adjusted in length allows the leader distance to be changed without significant changes to the vertical position of the leader. Further, the linkage mechanism can be made simple and compact. This also results in a particularly compact design of the civil engineering machine overall, in particular with a relatively low overall height of the superstructure and linkage mechanism.
Eine besonders gute Verstellmöglichkeit des Mäklers ergibt sich nach einer Weiterbildung der Erfindung dadurch, dass der Teleskoparm um eine horizontale Schwenkachse schwenkbar an dem Oberwagen gelagert ist. Insbesondere kann der Teleskoparm in einem oberen Bereich des Oberwagens schwenkbar angelenkt sein. Der Teleskoparm beiziehungsweise der Anlenkmechanismus ist in einem unteren Bereich mit dem Mäkler verbunden, so dass der Mäkler nach vorne umlegbar ist. Zum Verschwenken des Teleskoparms kann ein Schwenkzylinder, insbesondere ein Hydraulikzylinder, vorgesehen sein.According to a development of the invention, a particularly good possibility of adjusting the leader results from the fact that the telescopic arm is mounted on the superstructure so that it can pivot about a horizontal pivot axis. In particular, the telescopic arm can be pivoted in an upper area of the superstructure. The telescopic arm or the linkage mechanism is connected to the leader in a lower area, so that the leader can be folded forward. A swivel cylinder, in particular a hydraulic cylinder, can be provided for swiveling the telescopic arm.
Eine weitere vorteilhafte Ausführungsvariante der erfindungsgemäßen Tiefbaumaschine besteht darin, dass der Mäkler an dem Teleskoparm über eine Halteeinrichtung gehalten ist und dass der Mäkler parallel zu seiner Linearführung an der Halteeinrichtung verschiebbar gelagert ist. Die Halteeinrichtung kann insbesondere einen Tragbalken aufweisen, welcher schwenkbar am Teleskoparm gelagert ist. Der Mäkler ist vorzugsweise parallel zu seiner Linearführung entlang dem Tragbalken der Halteeinrichtung verschiebbar gelagert. So kann in einfacher Weise die vertikale Lage des Mäklers und die Relativposition zum Teleskoparm verändert werden.A further advantageous variant of the civil engineering machine according to the invention is that the leader is held on the telescopic arm via a holding device and that the leader is slidably mounted parallel to its linear guide on the holding device. The holding device can in particular a Have support beam, which is pivotally mounted on the telescopic arm. The leader is preferably mounted displaceably parallel to its linear guide along the supporting beam of the holding device. In this way, the vertical position of the leader and the position relative to the telescopic arm can be changed in a simple manner.
Für eine weitere Verbesserung der Verstellmöglichkeiten des Mäklers ist es nach einer Ausführungsform der Erfindung bevorzugt, dass die Halteeinrichtung eine Schwenkeinheit aufweist, mit welcher der Mäkler um eine Mäkler-Schwenkachse verschwenkbar ist, welche parallel zur Linearführung des Mäklers gerichtet ist. Somit kann der Mäkler um eine Hochachse, welche parallel zur Linearführung gerichtet ist, verstellt und eingestellt werden.To further improve the adjustment possibilities of the leader, it is preferred according to one embodiment of the invention that the holding device has a pivoting unit with which the leader can be pivoted about a leader pivot axis, which is directed parallel to the linear guide of the leader. The leader can thus be adjusted and adjusted about a vertical axis which is directed parallel to the linear guide.
Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass an der Halteeinrichtung eine lösbare Verbindungseinheit angeordnet ist, mit welcher der Mäkler leicht lösbar mit dem Teleskoparm verbindbar ist. Somit kann der Mäkler bei Bedarf mechanisch vom Teleskoparm gelöst und hiervon entfernt werden.A further advantageous embodiment of the invention is that a detachable connection unit is arranged on the holding device, with which the leader can be easily detachably connected to the telescopic arm. This means that the leader can be mechanically detached from the telescopic arm and removed from it if necessary.
Besonders vorteilhaft ist es dabei, dass die lösbare Verbindungseinheit automatisch betätigbar ist. Vorzugsweise kann die Verbindungseinheit hydraulisch betätigbare Haltebolzen aufweisen, welche zwischen einer Verriegelungsposition und einer Entriegelungsposition verstellbar sind. Auf diese Weise kann eine leichte mechanische Entkopplung zwischen Mäkler und Teleskoparm erfolgen, etwa wenn der Mäkler in eine etwa horizontale Transportposition umgelegt wird. Dabei können bestehende Leitungsverbindungen, insbesondere für Energie- und/oder Datenleitungen, ebenfalls getrennt werden oder vorzugsweise weiter zwischen dem Mäkler und dem Teleskoparm bestehen bleiben. Hierzu können die Verbindungsleitungen mit entsprechenden Zusatzlängen ausgebildet sein.It is particularly advantageous that the detachable connection unit can be actuated automatically. The connection unit can preferably have hydraulically actuable retaining bolts which can be adjusted between a locking position and an unlocking position. In this way, a slight mechanical decoupling can take place between leader and telescopic arm, for example when the leader is folded into an approximately horizontal transport position. Existing line connections, in particular for energy and/or data lines, can also be separated or preferably remain between the leader and the telescopic arm. For this purpose, the connecting lines can be designed with corresponding additional lengths.
Besonders vorteilhaft ist es nach einer Weiterbildung der Erfindung, dass der Mäkler aus einer im Wesentlichen vertikalen Betriebsposition in eine im Wesentlichen horizontale Ruheposition verschwenkbar ist, welche sich in Längsrichtung vor dem Oberwagen befindet. Es ist somit ein einfaches Umlegen des Mäklers in eine horizontale Ruhe- oder Transportposition möglich.According to a development of the invention, it is particularly advantageous that the leader can be pivoted from a substantially vertical operating position into a substantially horizontal rest position, which is located in front of the superstructure in the longitudinal direction. It is thus possible to simply switch the leader to a horizontal resting or transport position.
Besonders zweckmäßig ist es dabei, dass der Mäkler in der Ruheposition auf einer Ablage abgelegt ist und dass der Mäkler in der abgelegten Ruheposition auf der Ablage durch Lösen der Verbindungseinheit von dem Teleskoparm lösbar ist. Das Lösen kann dabei teilweise oder vollständig erfolgen.It is particularly expedient here that the leader is placed on a shelf in the rest position and that the leader is placed on the shelf in the laid rest position can be detached from the telescopic arm by detaching the connection unit. The loosening can take place partially or completely.
Eine weitere bevorzugte Ausgestaltung der Erfindung besteht darin, dass der Unterwagen als ein gleisgebundener Unterwagen mit einem Fahrwerk mit Rädern zum Fahren auf Bahngleisen ausgebildet ist. Durch die Kombination mit einem Anlenkmechanismus mit einem Teleskoparm kann eine gleisgebundene Tiefbaumaschine geschaffen werden, welche bei einem umgelegten Mäkler eine besonders kompakte Bauhöhe aufweist. Dies ist insbesondere für ein Verfahren entlang von Bahngleisen vorteilhaft, für welche im Hinblick auf Tunnel und bestehende Oberleitungen strikte Höhenbegrenzungen gelten.Another preferred embodiment of the invention is that the undercarriage is designed as a rail-bound undercarriage with a chassis with wheels for driving on railroad tracks. By combining it with a linkage mechanism with a telescopic arm, a track-bound civil engineering machine can be created which has a particularly compact overall height when the leader is folded over. This is particularly advantageous for travel along railroad tracks, which have strict height limitations with regard to tunnels and existing overhead lines.
Besonders vorteilhaft ist es dabei, dass die Ablage zum Ablegen des Mäklers auf einem Transportwagen ausgebildet ist. Dieser Transportwagen kann insbesondere selbst ein gleisgebundener Transportwagen mit Rädern zum Fahren auf Bahngleisen sein. Der Transportwagen kann als ein Zusatzwagen an den Unterwagen der Tiefbaumaschine angekoppelt werden. Der Mäkler kann dabei auf dem Transportwagen abgelegt werden, wobei eine Verbindung zwischen Mäkler und dem Teleskoparm vollständig oder teilweise getrennt ist, wobei eine Verbindung ausschließlich durch Verbindungsleitungen gebildet ist.It is particularly advantageous that the deposit for depositing the leader is designed on a trolley. In particular, this transport vehicle itself can be a rail-mounted transport vehicle with wheels for driving on railroad tracks. The transport carriage can be coupled as an additional carriage to the undercarriage of the civil engineering machine. The leader can be placed on the trolley, with a connection between the leader and the telescopic arm is completely or partially separated, with a connection being formed exclusively by connecting lines.
Nach einer Weiterbildung der Erfindung ist es bevorzugt, dass der Teleskoparm hydraulisch betätigbar ist. Vorzugsweise kann hierbei innerhalb des Teleskoparms ein Hydraulikzylinder angeordnet sein. Der Teleskoparm kann vorzugsweise einen eckigen, vorzugsweise rechteckigen Querschnitt aufweisen, so dass der Teleskoparm für eine sichere lineare Führung des Mäklers beim Ein- und Austeleskopieren sorgen kann. Der Teleskoparm kann über mindestens einen Schwenkzylinder um die horizontale Schwenkachse verstellt und so gegenüber der Horizontalen angewinkelt werden.According to a development of the invention, it is preferred that the telescopic arm can be actuated hydraulically. A hydraulic cylinder can preferably be arranged within the telescopic arm. The telescopic arm can preferably have an angular, preferably rectangular cross-section, so that the telescopic arm can ensure reliable linear guidance of the leader when telescoping in and out. The telescopic arm can be adjusted about the horizontal pivot axis via at least one pivot cylinder and thus be angled relative to the horizontal.
Besonders zweckmäßig ist es nach einer weiteren Ausführungsvariante der Erfindung, dass die Verbindungseinheit schwenkbar gegenüber dem Teleskoparm gelagert ist. Zum Verschwenken kann dabei an der Verbindungseinheit ebenfalls ein weiterer Stellzylinder vorgesehen sein. Durch die Verschwenkbarkeit der Verbindungseinheit gegenüber dem Teleskoparm kann bei einem Anstellwinkel des Teleskoparms sichergestellt werden, dass der Mäkler weiterhin eine vertikale Ausrichtung aufweist.According to a further embodiment variant of the invention, it is particularly expedient for the connecting unit to be pivotably mounted relative to the telescopic arm. Another actuating cylinder can also be provided on the connecting unit for pivoting purposes. Due to the pivotability of the connecting unit relative to the telescopic arm, at an angle of the telescopic arm ensure that the leader remains vertical.
Generell kann als Bauarbeitsgerät an der Tiefbaumaschine jedes Gerät angebracht werden. Besonders vorteilhaft ist es nach einer Ausführungsvariante der Erfindung, dass das Bauarbeitsgerät an dem Arbeitsschlitten einen Rüttler, einen Bohrantrieb, ein Rammgerät, eine Spundwandbohlenpresse oder eine Fräse aufweist. Das Rammgerät kann insbesondere eine Schlag- oder Hammereinheit umfassenIn general, any device can be attached to the civil engineering machine as a construction device. According to one embodiment variant of the invention, it is particularly advantageous for the construction equipment to have a vibrator, a drilling drive, a piling device, a sheet pile press or a cutter on the working carriage. The piling device can in particular comprise an impact or hammer unit
Mit einem Bohrantrieb kann ein Bohrgerät geschaffen werden, mit welchem insbesondere Bohrpfähle oder Gründungspfähle im Boden erstellt werden, wobei ein erstelltes Bohrloch mit einer vorzugswiese aushärtbaren Masse, insbesondere Beton, verfüllt wird. Das Bohrgerät kann auch zum Einbringen von Bohr- oder Schraubankern für Gründungsmaßnahmen dienen.A drill drive can be used to create a drilling device with which, in particular, bored piles or foundation piles can be created in the ground, with a borehole that has been created being filled with a preferably hardenable compound, in particular concrete. The drill can also be used to insert drill or screw anchors for foundation measures.
Mittels einer Fräse können vertikale Schlitze im Boden erstellt werden, welche nach Auffüllen mit einer aushärtbaren Masse Schlitzwandsegmente oder zusammenhängende Schlitzwände im Boden bilden. Mittels eines Rüttlers, eines Rammgerätes, eines Hammers oder einer Spundwandbohlenpresse können pfahlförmige oder bohlenartige Gründungselemente in den Boden eingetrieben werden.Vertical slits can be created in the ground using a cutter, which, after being filled with a hardenable mass, form diaphragm wall segments or connected diaphragm walls in the ground. Pile-like or plank-like foundation elements can be driven into the ground using a vibrator, a piling device, a hammer or a sheet pile press.

Zum Ablegen wird der Mäkler 50 vorzugsweise nach einem Schwenken des Mäklers durch die Schwenkeinrichtung 48 um 90° entlang einer Achse parallel zur Längsrichtung des Mäklers über den Anlenkmechanismus 40 am Oberwagen 30 in eine im Wesentlichen horizontale Position gebracht und unmittelbar oder vorzugsweise nach einem Schwenken um 90° auf die Seite auf die Ablage 82 des Zusatzwagens 80 abgelegt. Das Verschwenken um 90° erfolgt vorzugsweise bei vertikalem Mast. Anschließend kann die Verbindungseinheit 45 zwischen dem Teleskoparm 42 und der Halteeinrichtung 46 des Anlenkmechanismus 40 gelöst werden. Nun kann der Teleskoparm 42 wieder eingezogen werden. Wahlweise oder ergänzend kann der abgelegte Mäkler 50 auf dem Zusatzwagen 80 seitlich und/oder in Gleisrichtung verschoben werden, um den Schwerpunkt der Einheit aus Mäkler 50 und Arbeitsschlitten 60 möglichst nahe in die Mitte des Zusatzwagens 80 zu bringen. Der Mastkopf 56 kann abgeklappt werden, um ein seitliches Überstehen über die Breite des Zusatzwagens 80 zu vermeiden. Dabei können Leitungsverbindungen 66 zwischen dem Teleskoparm 42 am Oberwagen 30 und dem auf dem Zusatzwagen 80 abgelegten Mäkler 50 verbleiben. Die Leitungsverbindungen können Energie- und/oder Datenleitungen sein. Dies ermöglicht, dass bei Erreichen einer weiteren Baustelle der Mäkler 50 durch Ausfahren des Teleskoparms 42 und Schließen der Verbindungseinheit 45 nahezu automatisch wieder mit dem Oberwagen verbunden werden kann, ohne dass die Leitungsverbindungen 66 vor Arbeitsaufnahme neu hergestellt werden müssen.To set it down,
