Description

Die Erfindung betrifft ein Bauarbeitsgerät nach dem Oberbegriff des Anspruchs 1.The invention relates to a construction work implement according to the preamble of claim 1.

Ein solches Bauarbeitsgerät, insbesondere Bohr- oder Rammgerät, umfasst ein Trägerfahrzeug und einen an dem Trägerfahrzeug schwenkbar gelagerten Mast zum Führen eines Arbeitsschlittens. Der Arbeitsschlitten kann hierbei insbesondere zur Aufnahme eines Bohrantriebes oder einer Rammeinrichtung dienen.Such a construction work implement, in particular boring or pile driving apparatus, comprises a carrier vehicle and a mast pivotably mounted on the carrier vehicle for guiding a work carriage. The working carriage can serve in this case in particular for receiving a drilling drive or a ramming device.

Bekannte Bauarbeitsgeräte der oben genannten Art sind insbesondere mobile Bauarbeitsgeräte, deren Mast zu Transportzwecken beispielsweise von einer vertikalen Arbeitsstellung in eine im Wesentlichen horizontale Transportstellung verschwenkt werden kann, wie zum Beispiel aus Dokument DE A1-2 275 604 bekannt.Known construction work equipment of the above type are in particular mobile construction equipment whose mast can be pivoted for transport purposes, for example, from a vertical working position in a substantially horizontal transport position, such as document DE A1-2 275 604 known.

Außerdem ist es bekannt, dass der Mast gegenüber dem Trägerfahrzeug in der Betriebsstellung geringfügig verkippt werden kann, um eine Neigung der Bodenoberfläche auszugleichen oder um von der Vertikalen abweichende Bohrungen durchführen zu können.In addition, it is known that the mast can be slightly tilted relative to the carrier vehicle in the operating position in order to compensate for a slope of the ground surface or to perform deviations from the vertical holes can.

Häufig kann der Mast, insbesondere auch aufgrund der Verschwenkbarkeit in die Transportposition, soweit verstellt werden, dass er außerhalb eines sicheren Bereichs für die Standsicherheit des Geräts oder die Stabilität des Geräts verfahren werden kann. Bei einem Aufrichten des Mastes aus der Transportstellung oder einer Zusammenbausituation müssen auch Bereiche durchfahren werden können, in denen ein sicheres Arbeiten des Bauarbeitsgeräts nicht möglich ist.Often, the mast, in particular due to the pivotability in the transport position, be adjusted so far that it can be moved outside a safe area for the stability of the device or the stability of the device. When erecting the mast from the transport position or an assembly situation, it must also be possible to pass through areas in which safe working of the construction work implement is not possible.

Zum Einschränken der Verstellmöglichkeiten des Mastes im Arbeitsbetrieb ist es bekannt, mechanische Anschläge zu verwenden, die nach dem Aufrichten des Mastes angebracht werden. Da der Anbau solcher Begrenzungseinrichtungen jedoch nicht immer sichergestellt werden kann, werden alternativ elektrische Überwachungseinrichtungen zur Überwachung des sicheren Bereichs der Mastverschwenkung eingesetzt. Derartige elektrische Überwachungseinrichtungen können jedoch ausfallen und sind daher ebenfalls nicht sicher.To restrict the adjustment of the mast in the working mode, it is known to use mechanical stops that are attached after the erection of the mast. However, since the cultivation of such limiting devices not can always be ensured, electrical monitoring devices are used to monitor the safe area of Mastverschwenkung alternatively. However, such electrical monitoring devices may fail and are therefore also not safe.

Der Erfindung liegt die Aufgabe zugrunde, ein Bauarbeitsgerät bereitzustellen, welches eine sichere und einfach zu überwachende Mastverschwenkung ermöglicht.The invention has for its object to provide a construction implement, which allows a safe and easy to monitor Mastverschwenkung.

Die Aufgabe wird erfindungsgemäß durch ein Bauarbeitsgerät mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object is achieved by a construction implement with the features of claim 1. Preferred embodiments of the invention are specified in the dependent claims.

Das erfindungsgemäße Bauarbeitsgerät ist dadurch gekennzeichnet, dass im Bereich eines Schwenkgelenks zwischen dem Mast und dem Trägerfahrzeug mindestens zwei mechanische Anzeigeelemente vorgesehen sind, welche durch ein Verschwenken des Mastes relativ zu dem Trägerfahrzeug relativ zueinander bewegbar, insbesondere drehbar, sind und eine Neigung des Mastes relativ zu dem Trägerfahrzeug anzeigen.The construction work apparatus according to the invention is characterized in that at least two mechanical display elements are provided in the region of a pivot joint between the mast and the carrier vehicle, which are movable relative to each other by a pivoting of the mast relative to the carrier vehicle, in particular rotatable, and an inclination of the mast relative to indicate the carrier vehicle.

Ein erster Grundgedanke der Erfindung besteht darin, eine visuelle Überwachungsmöglichkeit zu schaffen, wobei der Fahrer des Bauarbeitsgeräts durch Überwachung einer visuellen Anzeige erkennen kann, ob sich der Mast noch in einem sicheren Arbeitsbereich befindet.A first basic idea of the invention is to provide a visual monitoring possibility, whereby the driver of the construction work device can recognize by monitoring a visual display whether the mast is still in a safe working area.

Ein zweiter Grundgedanke der Erfindung kann darin gesehen werden, eine visuelle Anzeigeeinrichtung bereitzustellen, die direkt im Bereich eines Schwenkgelenks zwischen Mast und Trägerfahrzeug angeordnet ist. Die Anzeigeeinrichtung umfasst zwei mechanische Anzeigeelemente, die sich bei einer Verschwenkung des Mastes gegenüber dem Trägerfahrzeug relativ zueinander bewegen und hierdurch ein Maß für die Mastneigung anzeigen. Durch die direkt am Schwenkgelenk angeordnete Anzeigeeinrichtung wird eine Verfälschung des angezeigten Werts für die Mastneigung weitgehend ausgeschlossen.A second basic idea of the invention can be seen to provide a visual display device which is arranged directly in the region of a pivot joint between the mast and the carrier vehicle. The display device comprises two mechanical display elements which move relative to one another when the mast is pivoted relative to the carrier vehicle and thereby indicate a measure of the mast inclination. Due to the display device arranged directly on the swivel joint, a distortion of the displayed value for the mast inclination is largely excluded.

In einer bevorzugten Ausgestaltung umfasst ein erstes mechanisches Anzeigeelement einen Zeiger und ein zweites mechanisches Anzeigeelement eine Anzeigetafel oder umgekehrt. Unter einem Zeiger wird vorliegend jegliches Element verstanden, welches auf einen bestimmten Bereich der Anzeigetafel zeigen kann, beispielsweise auch eine Markierung, eine Einkerbung oder beliebig geformte Zeigerelemente. Die Anzeigetafel kann eine Skala oder Markierung aufweisen.In a preferred embodiment, a first mechanical display element comprises a pointer and a second mechanical display element comprises a display panel or vice versa. A pointer is understood here to mean any element which can point to a specific area of the display panel, for example also a marking, a notch or arbitrarily shaped pointer elements. The scoreboard may have a scale or mark.

Besonders bevorzugt ist es nach der Erfindung, dass die Anzeigetafel einen ersten Bereich aufweist, welcher eine sichere Mastneigung anzeigt, und einen zweiten Bereich, welcher eine unsichere Mastneigung anzeigt. Die Bereiche können unterschiedliche Einfärbungen aufweisen, beispielsweise kann der erste Bereich mit einer grünen Einfärbung und der zweite Bereich mit einer roten Einfärbung versehen sein. Der Zeiger zeigt bei einer sicheren Mastneigung auf den ersten Bereich und bei einer unsicheren Mastneigung auf den zweiten Bereich der Anzeigetafel.It is particularly preferred according to the invention that the display panel has a first area indicating a safe mast tilt and a second area indicating an unsafe mast tilt. The areas may have different colorations, for example, the first area may be provided with a green tint and the second area with a red tint. The pointer points to the first area with a secure mast slope and to the second area of the scoreboard when the mast is unsafe.

Weiterhin ist es nach der Erfindung bevorzugt, dass ein erstes mechanisches Anzeigeelement mit dem Trägerfahrzeug und ein zweites mechanisches Anzeigeelement mit dem Mast verbunden ist. Die an dem Trägerfahrzeug beziehungsweise dem Mast angeordneten Anzeigeelemente sind vorzugsweise so eingerichtet, dass sie sich zusammen mit dem Trägerfahrzeug beziehungsweise dem Mast bewegen, so dass durch eine Relativbewegung zwischen Trägerfahrzeug und Mast eine entsprechende Relativbewegung zwischen den Anzeigeelementen bewirkt wird.Furthermore, it is preferred according to the invention that a first mechanical display element is connected to the carrier vehicle and a second mechanical display element is connected to the mast. The display elements arranged on the carrier vehicle or the mast are preferably arranged such that they move together with the carrier vehicle or the mast, so that a relative movement between the display elements is effected by a relative movement between the carrier vehicle and the mast.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das erste Anzeigeelement drehbar am Trägerfahrzeug oder das zweite Anzeigeelement drehbar am Mast gelagert ist. Durch die drehbare Lagerung des entsprechenden Anzeigeelements kann beispielsweise die Anzeige kalibriert werden, also der Übergang zwischen sicherem und unsicherem Betrieb eingestellt werden.In a preferred embodiment of the invention it is provided that the first display element is rotatably mounted on the carrier vehicle or the second display element rotatably mounted on the mast. By the rotatable mounting of the corresponding display element, for example, the display can be calibrated, so the transition between safe and unsafe operation can be set.

Zur zusätzlichen Überwachung der Mastneigung ist es bevorzugt, dass ein Sensorelement vorgesehen ist, welches sich zusammen mit dem ersten oder dem zweiten Anzeigeelement bewegt und bei Erreichen einer vorbestimmten Neigung des Mastes eine Auslöseposition einnimmt, in welcher ein Signal ausgelöst wird. Vorzugsweise handelt es sich bei dem Sensorelement um eine elektrische Überwachungseinrichtung, insbesondere einen elektrischen Endschalter. Durch die in unmittelbarer Nähe zu dem Sensorelement angeordnete Anzeigeeinrichtung lässt sich der Sensor beziehungsweise die Mastneigung überwachen.For additional monitoring of the mast tilt, it is preferred that a sensor element is provided which moves together with the first or the second display element and occupies a triggering position upon reaching a predetermined inclination of the mast, in which a signal is triggered. The sensor element is preferably an electrical monitoring device, in particular an electrical limit switch. By the arranged in close proximity to the sensor element display device, the sensor or the mast tilt can be monitored.

In einer vorteilhaften Ausgestaltung ist das Sensorelement zum Verändern der Auslöseposition bewegbar und/oder versetzbar an dem Anzeigeelement befestigt. Vorzugsweise entspricht die Auslöseposition des Sensorelements einer Stellung des Zeigers im zweiten Bereich der Anzeigetafel oder in einem Grenzbereich zwischen erstem und zweitem Bereich.In an advantageous embodiment, the sensor element for changing the release position is movable and / or displaceable attached to the display element. Preferably, the triggering position of the sensor element corresponds to a position of the pointer in the second region of the display panel or in a boundary region between the first and second region.

Ein besonders vielfältig einsetzbares Bauarbeitsgerät wird dadurch erzielt, dass das Trägerfahrzeug eine Basis und einen an der Basis schwenkbar gelagerten Auslegerarm aufweist, an welchem seinerseits der Mast schwenkbar gelagert ist, dass das erste oder das zweite Anzeigelement an dem Auslegerarm drehbar gelagert ist und dass ein Getriebe vorgesehen ist, welches das an dem Auslegerarm drehbar gelagerte Anzeigeelement bei einer Verschwenkung des Auslegerarms gegenüber der Basis oder dem Mast verdreht, um eine Neigung des Mastes gegenüber der Basis des Trägerfahrzeuges anzuzeigen.A particularly versatile construction work implement is achieved in that the carrier vehicle has a base and a pivotally mounted on the base arm, on which in turn the mast is pivotally mounted, that the first or the second display element is rotatably mounted on the cantilever arm and that a transmission is provided, which rotates the rotatably mounted on the cantilever arm display element upon pivoting of the cantilever arm relative to the base or the mast to indicate an inclination of the mast with respect to the base of the host vehicle.

Der Mast ist gemäß dieser Ausführungsform also über zwei koaxiale Schwenkachsen an dem Trägerfahrzeug, insbesondere der Basis des Trägerfahrzeugs, angelenkt. Dies ermöglicht neben einer Verschwenkung des Mastes auch eine achsparallele Bewegung beziehungsweise Verschiebung des Mastes relativ zum Trägerfahrzeug und ein Anheben und Senken des Mastes. Das durch die beiden Schwenkachsen und den Auslegerarm gebildete Doppelgelenk erhöht somit beträchtlich die Einsatzmöglichkeiten des Bauarbeitsgeräts.The mast is thus articulated according to this embodiment via two coaxial pivot axes on the carrier vehicle, in particular the base of the carrier vehicle. This allows not only a pivoting of the mast but also an axis-parallel movement or displacement of the mast relative to the carrier vehicle and a raising and lowering of the mast. The double joint formed by the two pivot axes and the boom thus considerably increases the capabilities of the construction equipment.

Um auch bei einem solchen Doppel- oder Mehrfachgelenk eine einfache, visuelle Anzeige der Mastneigung zu ermöglichen, kann die Anzeigeeinrichtung im Bereich eines der Schwenkgelenke angeordnet sein und zumindest eines der Anzeigeelemente entsprechend einer Schwenkbewegung um das jeweils andere Schwenkgelenk verstellt werden, so dass insgesamt die Mastneigung gegenüber der Basis des Trägerfahrzeugs angezeigt wird.In order to enable a simple, visual display of the mast tilt even with such a double or multiple joint, the display device can be arranged in the region of one of the pivot joints and at least one of the display elements are adjusted in accordance with a pivoting movement about the other pivot joint, so that overall mast tilt is displayed relative to the base of the host vehicle.

Eines der beiden Anzeigeelemente ist bei dieser bevorzugten Ausführung an dem Auslegerarm gelagert. Das jeweils andere Anzeigeelement kann entweder an der Basis des Trägerfahrzeugs oder am Mast angeordnet sein. Dementsprechend ist die Anzeigeeinrichtung mit den beiden Anzeigeelementen entweder im Bereich der Schwenkachse zwischen Basis und Auslegerarm oder zwischen Auslegerarm und Mast angeordnet. Das an dem Auslegerarm gelagerte Anzeigeelement wird dabei durch das Getriebe jeweils in einer Weise bewegt beziehungsweise verdreht, dass die Gesamtverschwenkung des Mastes gegenüber der Basis, unabhängig von der Verschwenkung um die jeweils andere Schwenkachse, angezeigt wird.One of the two display elements is mounted on the cantilever arm in this preferred embodiment. The respective other display element can be arranged either at the base of the carrier vehicle or on the mast. Accordingly, the display device with the two display elements either in the region of the pivot axis between the base and cantilever arm or between cantilever and Mast arranged. The display element mounted on the cantilever arm is respectively moved or rotated by the gear in such a way that the total pivoting of the mast relative to the base, regardless of the pivoting about the respective other pivot axis, is displayed.

Für ein korrektes Anzeigen der tatsächlichen Mastneigung ist insbesondere vorgesehen, dass das Getriebe eine relative Drehposition des an dem Auslegerarm gelagerten Anzeigeelements gegenüber der Basis oder dem Mast konstant hält, unabhängig von einer Verschwenkung des Auslegerarms gegenüber der Basis beziehungsweise dem Mast.For a correct indication of the actual mast inclination is provided in particular that the transmission keeps a relative rotational position of the mounted on the cantilever arm display element relative to the base or the mast, regardless of a pivoting of the cantilever arm relative to the base or the mast.

Eine konstruktiv bevorzugte Möglichkeit besteht darin, dass das Getriebe ein Gestängegetriebe, insbesondere ein Parallelogramm-Gestängegetriebe, aufweist. Das Gestängegetriebe umfasst ein Gestänge oder eine Getriebestange, welche einerseits an dem Anzeigeelement und andererseits an dem Trägerfahrzeug, insbesondere der Basis des Trägerfahrzeugs oder dem Mast, angelenkt sein kann. Durch das Gestänge oder die Getriebestange ist das Anzeigeelement verstellbar, insbesondere verdrehbar.A structurally preferred possibility is that the transmission has a linkage, in particular a parallelogram linkage. The linkage gear comprises a linkage or a gear rod, which may be hinged on the one hand to the display element and on the other hand to the carrier vehicle, in particular the base of the carrier vehicle or the mast. Through the linkage or the gear rod, the display element is adjustable, in particular rotatable.

Das Gestänge des Gestängegetriebes bildet vorzugsweise eine Seite eines Parallelogramms, dessen Ecken durch die Anlenkpunkte des Gestänges und die beiden Schwenkachsen gebildet werden. Hierdurch kann das zu verstellende Anzeigeelement entsprechend einer Verschwenkung des Auslegerarms verdreht beziehungsweise verschwenkt werden.The linkage of the linkage gear preferably forms one side of a parallelogram whose corners are formed by the articulation points of the linkage and the two pivot axes. As a result, the display element to be adjusted can be rotated or pivoted in accordance with a pivoting of the extension arm.

Eine besonders sichere Anzeige der Mastneigung kann dadurch erzielt werden, dass die Anzeigeelemente so positioniert sind, dass sie von einem Fahrer des Bauarbeitsgeräts aus seinem Fahrerstand heraus sichtbar sind.A particularly reliable display of the mast tilt can be achieved by the display elements being positioned so that they are visible from a driver of the construction implement from his driver's cab.

Weiterhin ist es bevorzugt, dass mindestens zwei Anzeigeeinrichtungen vorgesehen sind, welche jeweils mindestens zwei zueinander bewegbare Anzeigeelemente umfassen, wobei eine erste Anzeigeeinrichtung eine Mastquerneigung und eine zweite Anzeigeeinrichtung eine Mastlängsneigung anzeigt. Durch die Verschwenkmöglichkeit des Mastes sowohl in Quer- als auch in Längsrichtung wird ein vielfältig einsetzbares Bauarbeitsgerät bereitgestellt, wobei durch die entsprechenden Anzeigen eine besonders sichere Verschwenkung des Mastes sowohl in Quer- als auch in Längsrichtung erzielt wird.Furthermore, it is preferred that at least two display devices are provided, each of which comprises at least two mutually movable display elements, wherein a first display device displays a mast bank and a second display device a mast longitudinal inclination. Due to the possibility of pivoting the mast both in the transverse and in the longitudinal direction of a multi-purpose construction equipment is provided, wherein the corresponding displays a particularly safe pivoting of the mast in both the transverse and longitudinal direction is achieved.

Fig. 1 zeigt einen Ausschnitt eines Bauarbeitsgeräts 10 mit einem Trägerfahrzeug 12 und einem insbesondere im Frontbereich des Trägerfahrzeugs 12 um eine oder mehrere horizontale Schwenkachsen schwenkbar gelagerten Mast 14. Das Trägerfahrzeug 12 kann in grundsätzlich bekannter Weise einen Unterwagen, beispielsweise mit Raupenfahrwerk, und einen daran um eine vertikale Drehachse drehbar gelagerten Oberwagen umfassen, an welchem der Mast 14 angelegt ist. An dem Mast 14 ist eine Führungseinrichtung 16 vorgesehen, entlang welcher ein Schlitten, beispielsweise ein Bohr- oder Rammschlitten, in Längsrichtung des Mastes 14 verfahren werden kann. Fig. 1 shows a section of a construction work device 10 with a carrier vehicle 12 and a particular in the front region of the carrier vehicle 12 about one or more horizontal pivot axes pivotally mounted mast 14. The carrier vehicle 12 may in a basically known manner an undercarriage, for example with crawler tracks, and one about a vertical Include rotation axis rotatably mounted uppercarriage, on which the mast 14 is applied. On the mast 14, a guide device 16 is provided, along which a carriage, for example a drilling or driving carriage, can be moved in the longitudinal direction of the mast 14.

Der Mast 14 kann mittels in der Figuren nicht im Detail dargestellter Hubzylinder in mehreren Richtungen gegenüber dem Trägerfahrzeug 12 verschwenkt werden. Die Verschwenkung des Mastes 14 kann einerseits in einem Arbeitsbetrieb des Bauarbeitsgeräts 10 erfolgen, um den Mast 14 der jeweiligen Geländesituation anpassen zu können. Hierzu kann der Mast 14 in einer Längsrichtung des Bauarbeitsgeräts 10 horizontal verschoben werden. Des Weiteren ist eine Längsneigung und/oder eine Querneigung des Mastes 14 möglich. Andererseits kann der Mast 14 auch in einen Bereich verschwenkt werden, in welchem ein sicherer Betrieb des Bauarbeitsgeräts 10 nicht mehr möglich ist. Eine solche Verschwenkung des Mastes 14 erfolgt insbesondere während eines Aufbau- oder Abbauvorgangs des Bauarbeitsgeräts 10, bei welchem der Mast 14 in eine Transportposition oder aus dieser heraus in die Betriebsposition verschwenkt wird.The mast 14 can be pivoted by means not shown in detail in the figures lifting cylinder in several directions relative to the carrier vehicle 12. The pivoting of the mast 14 can be done on the one hand in a working operation of the construction equipment 10 to adjust the mast 14 of the respective terrain situation. For this purpose, the mast 14 can be moved horizontally in a longitudinal direction of the construction implement 10. Furthermore, a longitudinal inclination and / or a Bank of the mast 14 possible. On the other hand, the mast 14 can also be pivoted into an area in which safe operation of the construction work implement 10 is no longer possible. Such a pivoting of the mast 14 takes place in particular during a construction or dismantling operation of the construction work apparatus 10, in which the mast 14 is pivoted into a transport position or out of this into the operating position.

Der Mast 14 ist über ein Doppelgelenk, das heißt zwei koaxial zueinander angeordnete Schwenkgelenke 24, 26, an einer Basis 20 des Trägerfahrzeugs 12 gelagert. Dies ermöglicht es, neben einer Verschwenkung den Mast 14 unter Beibehaltung seines Winkels relativ zu der Basis 20 anzuheben oder zu senken und gegenüber der Basis 20, ebenfalls unter Beibehaltung seiner Ausrichtung, horizontal zu bewegen. Damit kann beispielsweise der Abstand des Mastes 14 von dem Trägerfahrzeug 12, insbesondere der Basis 20, verändert werden, so dass zur genauen Positionierung des Mastes 14 nicht das gesamte Trägerfahrzeug 12 verfahren werden muss.The mast 14 is mounted on a base 20 of the carrier vehicle 12 via a double joint, that is, two pivot joints 24, 26 arranged coaxially with one another. This makes it possible, besides pivoting, to raise or lower the mast 14 while maintaining its angle relative to the base 20 and to move it horizontally with respect to the base 20 while maintaining its orientation. Thus, for example, the distance of the mast 14 from the carrier vehicle 12, in particular the base 20, to be changed, so that not the entire carrier vehicle 12 must be moved for accurate positioning of the mast 14.

Das Trägerfahrzeug 12 umfasst einen Auslegerarm 22, der an der Basis 20 um ein erstes Schwenkgelenk 24 drehbar gelagert ist. Der Mast 14 ist um ein zweites Schwenkgelenk 26 drehbar an dem Auslegerarm 22 gelagert. Mittels Hubzylinder 18, welche einerseits an der Basis 20 des Trägerfahrzeugs 12 und andererseits an dem Auslegerarm 22 angelenkt sind, kann der Auslegerarm 22 gegenüber der Basis 20 verschwenkt werden. Der Auslegerarm 22 kann grundsätzlich auch als Teil des die beiden Schwenkgelenke 24, 26 umfassenden Doppelgelenks angesehen werden.The carrier vehicle 12 comprises a cantilever arm 22, which is rotatably mounted on the base 20 about a first pivot joint 24. The mast 14 is rotatably mounted on the cantilever arm 22 about a second pivot joint 26. By means of lifting cylinder 18, which are hinged on the one hand to the base 20 of the carrier vehicle 12 and on the other hand to the boom 22, the cantilever arm 22 can be pivoted relative to the base 20. The cantilever arm 22 can in principle also be regarded as part of the double joint comprising the two pivot joints 24, 26.

Im Bereich des zweiten Schwenkgelenks 26 ist eine Anzeigeeinrichtung 30 vorgesehen, die in den Figuren 2 und 3 vergrößert dargestellt ist. Die Anzeigeeinrichtung 30 umfasst ein erstes Anzeigeelement 32, welches an dem Auslegerarm 22 drehbar gelagert ist, und ein zweites Anzeigeelement 34, das am Mast 14 angeordnet ist. Das erste Anzeigeelement 32 weist einen Drehteller auf, an dem ein Zeiger 36 ausgebildet ist. Das zweite Anzeigeelement 34 umfasst eine insbesondere bogenförmige Anzeigetafel 38, die von dem Zeiger 36 überstrichen wird oder auf die der Zeiger 36 hindeutet.In the region of the second pivot joint 26, a display device 30 is provided which in the Figures 2 and 3 is shown enlarged. The display device 30 comprises a first display element 32, which is rotatably mounted on the cantilever arm 22, and a second display element 34, which is arranged on the mast 14. The first display element 32 has a turntable on which a pointer 36 is formed. The second display element 34 includes a particular arcuate display panel 38, which is swept by the pointer 36 or pointing to the pointer 36.

Durch eine Verschwenkung des Mastes 14 um das zweite Schwenkgelenk 26 wird die Anzeigetafel 38 gegenüber dem Zeiger 36 gedreht. Die Anzeigetafel 38 umfasst einen ersten Bereich 40, welcher eine sichere Mastneigung kennzeichnet, und einen zweiten Bereich 42, welcher eine unsichere Mastneigung angibt, bei welcher die Gefahr besteht, dass das Bauarbeitsgerät 10 kippt. Sobald die Verschwenkung des Mastes 14 ein vorbestimmtes Maß überschreitet, wandert der Zeiger 36 vom ersten Bereich 40 der Anzeigetafel 38 in den zweiten Bereich 42 der Anzeigetafel 38. Grundsätzlich wäre es auch möglich, die Positionen von erstem und zweitem Anzeigeelement gegenüber der dargestellten Ausführungsform zu vertauschen.By pivoting the mast 14 about the second pivot joint 26, the display panel 38 is rotated relative to the pointer 36. The display panel 38 includes a first region 40 indicative of a safe mast tilt, and a second region 42 indicative of an unsafe mast tilt at which there is a danger of the construction implement 10 tipping. As soon as the pivoting of the mast 14 exceeds a predetermined level, the pointer 36 moves from the first area 40 of the display panel 38 into the second area 42 of the display panel 38. In principle, it would also be possible to exchange the positions of the first and second display elements with respect to the illustrated embodiment ,

Neben einer Verschenkung um das zweite Schwenkgelenk 26 kann eine Verschwenkung des Mastes 14 auch durch eine Verschwenkung um das erste Schwenkgelenk 24 erzielt werden. Damit auch diese Verschwenkung von der Anzeigeeinrichtung 30 erfasst wird, umfasst die Anzeigeeinrichtung 30 ein Getriebe 60, welches das an dem Auslegerarm 22 drehbar gelagerte Anzeigeelement entsprechend der Verschwenkung des Auslegerarms 22 um das erste Schwenkgelenk 24 dreht. Das Getriebe 60 ist als Gestängegetriebe ausgebildet und umfasst eine Getriebestange 62, die außerhalb einer Verbindungsachse zwischen den Schwenkgelenken 24, 26 angeordnet ist und insbesondere parallel zu dieser verläuft. Ein erstes Ende der Getriebestange 62 ist an einem Festpunkt der Basis 20 des Trägerfahrzeugs 12 angelenkt und ein zweites Ende ist über einen Hebelarm 64 mit dem am Auslegerarm 22 gelagerten Anzeigeelement verbunden. Die Getriebestange 62 bildet mit der Verbindungsachse zwischen den Schwenkgelenken 24, 26 und geometrischen Verbindungslinien zwischen den Endpunkten der Getriebestange 62 und der Verbindungsachse ein Parallelogramm. Mit anderen Worten wird das Parallelogramm durch die Anlenkpunkte der Getriebestange 62 und die Schwenkgelenke 24, 26 definiert. Diese Punkte bilden die Eckpunkte des Parallelogramms.In addition to a gift for the second pivot joint 26, a pivoting of the mast 14 can also be achieved by pivoting about the first pivot joint 24. So that this pivoting is detected by the display device 30, the display device 30 comprises a gear 60, which rotates the rotatably mounted on the cantilever arm 22 display element according to the pivoting of the cantilever arm 22 about the first pivot joint 24. The transmission 60 is designed as a linkage gear and comprises a gear rod 62, which is arranged outside of a connecting axis between the pivot joints 24, 26 and in particular runs parallel thereto. A first end of the transmission rod 62 is hinged to a fixed point of the base 20 of the host vehicle 12 and a second end is connected via a lever arm 64 to the cantilever arm 22 mounted on the display element. The transmission rod 62 forms a parallelogram with the connection axis between the pivot joints 24, 26 and geometric connecting lines between the end points of the transmission rod 62 and the connection axis. In other words, the parallelogram is defined by the articulation points of the gear rod 62 and the pivot joints 24, 26. These points form the vertices of the parallelogram.

Durch das Getriebe 60 wird der Winkel des an dem Auslegerarm 22 gelagerten Anzeigeelements relativ zu der Basis 20 des Trägerfahrzeugs 12 konstant gehalten, unabhängig von der Verschwenkung des Auslegerarms 22 gegenüber der Basis 20. Grundsätzlich wäre es auch möglich, die Anzeigeeinrichtung 30 im Bereich des ersten Schwenkgelenks 24 anzuordnen und das an dem Auslegerarm 22 angeordnete Anzeigeelement bei einer Verschwenkung des Mastes 14 gegenüber dem Auslegerarm 22 in analoger Weise zu verstellen. Die Getriebestange 62 könnte in diesem Fall an einem Festpunkt des Mastes 14 gelagert sein.The transmission 60 keeps the angle of the display element mounted on the cantilever arm 22 constant relative to the base 20 of the host vehicle 12, regardless of the pivoting of the cantilever arm 22 relative to the base 20. In principle, it would also be possible for the display device 30 to be in the region of the first one Swivel joint 24 to arrange and adjust the arranged on the boom 22 display element at a pivoting of the mast 14 relative to the boom 22 in an analogous manner. The transmission rod 62 could be stored in this case at a fixed point of the mast 14.

Neben der visuellen Überwachung ist auch eine elektronische Überwachung der Mastneigung vorgesehen. Hierzu ist an einer Lagerplatte 52 ein Sensorelement 50 angeordnet, welches sich zusammen mit dem ersten Anzeigeelement 32 oder dem zweiten Anzeigeelement 34 gegenüber einem im Bereich des jeweils anderen Anzeigeelements angeordneten Auslöser 54 bewegt. Der Auslöser 54 ist als eine Schaltkulisse oder Nocke ausgebildet, die insbesondere fest mit dem Anzeigeelement, insbesondere dem Zeiger 36 oder der Anzeigetafel 38, verbunden ist. Sobald das Sensorelement 50 in den Bereich des Auslösers 54 gelangt oder diesen kontaktiert, wird ein Signal ausgelöst. Durch das Signal kann beispielsweise ein Warnton ausgelöst oder eine Verschwenkung des Mastes 14 gestoppt werden. Das Sensorelement 50 kann insbesondere als Endschalter bezeichnet werden und kann lösbar an dem Anzeigeelement angebracht sein.In addition to the visual monitoring, an electronic monitoring of the mast tilt is provided. For this purpose, a sensor element 50 is arranged on a bearing plate 52 which, together with the first display element 32 or the second display element 34, moves relative to a trigger 54 arranged in the region of the respective other display element. The trigger 54 is designed as a switching gate or cam, which is in particular firmly connected to the display element, in particular the pointer 36 or the display panel 38. As soon as the sensor element 50 reaches or contacts the region of the trigger 54, a signal is triggered. For example, a warning sound can be triggered by the signal or a pivoting of the mast 14 can be stopped. The sensor element 50 may be referred to in particular as a limit switch and may be releasably attached to the display element.

Die mit Bezug auf die Figuren 1 bis 3 beschriebene Anzeigeeinrichtung 30 dient insbesondere dem Anzeigen einer Längsneigung des Mastes 14, also einer Verschwenkung des Mastes 14 in eine Längsrichtung des Bauarbeitsgeräts 10. Eine zweite Ausführungsform einer Anzeigeeinrichtung 30 ist in Fig. 4 dargestellt. Die Anzeigeeinrichtung 30 gemäß Fig. 4 dient insbesondere dem Anzeigen einer Mastquerneigung, also einer Neigung des Mastes 14 quer zu einer Längsrichtung des Bauarbeitsgeräts 10. Vorzugsweise sind bei einem Bauarbeitsgerät 10 sowohl eine Anzeigeeinrichtung zum Anzeigen einer Mastlängsneigung als auch einer Anzeigeeinrichtung zum Anzeigen einer Mastquerneigung angeordnet.The referring to the FIGS. 1 to 3 In particular, the display device 30 described serves to indicate a longitudinal inclination of the mast 14, that is to say a pivoting of the mast 14 in a longitudinal direction of the construction implement 10. A second embodiment of a display device 30 is shown in FIG Fig. 4 shown. The display device 30 according to Fig. 4 is used in particular for displaying a mast bank, ie an inclination of the mast 14 transversely to a longitudinal direction of the construction work device 10. Preferably, both a display device for displaying a mast longitudinal inclination and a display device for displaying a mast bank are arranged in a construction work device 10.

Die Anzeigeeinrichtung 30 gemäß Fig. 4 umfasst ein an dem Trägerfahrzeug 12 angeordnetes, erstes Anzeigeelement 32, welches eine Anzeigetafel 38 aufweist, und ein an dem Mast 14 angeordnetes zweites Anzeigeelement, welches einen Zeiger umfasst. Der Zeiger 36 bewegt sich zusammen mit dem Mast 14 bei dessen Verschwenkung entlang der Anzeigetafel 38.The display device 30 according to Fig. 4 comprises a first display element 32 arranged on the carrier vehicle 12 and having a display panel 38, and a second display element arranged on the mast 14 and comprising a pointer. The pointer 36 moves along with the mast 14 as it pivots along the display panel 38th

Der Zeiger 36 ist an einer Lagerplatte 52 ausgebildet, welche gleichsam der Lagerung von Sensorelementen 50 dient. Das erste Anzeigeelement 32 umfasst einen Auslöser 54, welcher von dem Sensorelement 50 kontaktiert werden kann, wobei ein Signal ausgelöst werden kann.The pointer 36 is formed on a bearing plate 52, which serves as the storage of sensor elements 50. The first display element 32 comprises a trigger 54, which can be contacted by the sensor element 50, wherein a signal can be triggered.

Die Anzeigetafel 38 umfasst, analog der Ausführungsform gemäß Figuren 1 bis 3, einen ersten Bereich 40, welcher eine sichere Mastneigung kennzeichnet, und einen oder gegebenenfalls mehrere zweite Bereiche 42, die eine Neigung des Mastes 14 kennzeichnen, bei welcher die Stabilität des Bauarbeitsgeräts 10 gefährdet ist.The display panel 38 comprises, analogous to the embodiment according to FIG FIGS. 1 to 3 , a first area 40, which indicates a safe mast tilt, and one or possibly a plurality of second areas 42, which indicate an inclination of the mast 14, in which the stability of the construction implement 10 is at risk.
