- height access machines in the form of aerial work platforms which provide height access.
- the size and kinematics of the extension arm are adapted to the necessary work area.
- a so-called articulated arm boom is used, i.e. a two-part extension arm, in which the angle between the forearm and upper arm can be changed
- a telescope design on one or both arms also increases the work area.
- a crane attachment can be installed in place of the work basket in order to be able to move loads at height.
- Extendable supports are often required on the chassis in order to reach positions that extend as far out as possible with the work basket or the crane attachment and to ensure stability.
- the support system requires monitoring sensors, a mostly hydraulic drive and a control system.
- a drive is required if the chassis can be moved independently.
- a rotating tower is also always provided, on which the height access boom unit is mounted in order to vary quickly without having to maneuver the chassis To be able to move to work positions.
- counterweights, drive motors and operating elements must be provided in order to be able to operate the various adjusting elements on the height access boom unit.
- a chassis with the numerous assemblies is therefore required, the construction and manufacture of which is complex, but which is also available in a variety of ways with other work machines, such as excavators, with the basic functions mentioned.
- the height access boom unit does not carry a work cage but is provided with a crane attachment, or if a truck chassis is used as the chassis. It is always necessary to be able to position the center of gravity of the boom unit as close as possible to the axis of rotation in order to be able to use the given support surface and to ensure the stability of the height access machine at all times.
- a height access boom unit for a mobile height access machine with a chassis with wheels and / or crawler tracks and a rotating tower on the chassis, on which an elevating boom arm is mounted, is known.
- the cantilever arm is rotatably connected to the turret at one end on a horizontally or substantially horizontally extending pivot axis and can be provided with a height access means at another end.
- a tower adapter is arranged, which is arch-shaped, curved, curved, cranked or the like clasp-shaped and which extends from the first pivot axis, which is rotatably connected to the turret, to a second pivot axis, via which the cantilever arm is connected to the tower adapter, extends.
- the EP 1 344 741 A1 describes a self-propelled work vehicle, namely an aerial work platform or a crane, which comprises a motor-driven vehicle chassis with a driver's cab, a loading area with a turntable and a rotating and extending mast.
- the extension mast consists of an arc-shaped turret, which is rotatably arranged with the foot part in the middle on the turntable, and a support arm.
- GB 1 5151 114 A describes a work vehicle with a horizontal swivel arm that can be rotated about a vertical axis and a cantilever arm that can be rotated on the swivel arm about a likewise vertical axis.
- the present invention is therefore based on the object of providing a height access boom unit with which the above disadvantages can be prevented, which is therefore structurally particularly simple, at the same time compact and stable and can be used in a particularly versatile manner and is extremely stable has, and to provide a mobile height access machine and its use.
- the solution according to the invention is essentially based on arranging a movable tower adapter between the rotating tower and the cantilever arm, which is designed in any way arc-shaped, curved, curved, cranked or the like in the form of a clasp, the (approximately) concave side of the arc-shaped, curved, curved, cranked or the like clasp-shaped tower adapter faces the turret or the vertical or substantially vertical axis of rotation of the turret or faces the center of the turret, while the approximately convex side faces away from the turret.
- the tower adapter according to the invention therefore does not extend on a straight connecting line between the upper and the lower pivot axis, but rather extends to a large extent outside of a straight connecting line that is intended to be curved.
- the tower adapter Thanks to its angled, cranked or curved course, the tower adapter virtually engages around the units, such as motor housing, operator station, etc., placed on the rotating tower in the area of the axis of rotation. This allows the tower adapter to be set much steeper than, for example, the upper arm of an excavator arm. The tower adapter therefore reaches around the obstacles on the rotating tower.
- its end region which carries the second, upper pivot axis on which the cantilever arm attaches, is positioned above the turret, in particular above the axis of rotation. It is even possible to position the second pivot axis beyond the rear side of the turret on the opposite peripheral side.
- the upper end region of the tower adapter is provided with an arch shape, bend, curvature, cranking or the like clasp, which leads to the arch shape, bend, curvature, cranking or similar clasp of the lower end region of the tower adapter is formed in the opposite direction.
- the tower adapter is given an approximately S-shaped configuration. This in turn enables the end region of the tower adapter to be in the working position and an intermediate position essentially above the axis of rotation and the operator's cabin etc.
- the upper end region of the tower adapter can be of a lesser configuration than the configuration of the lower end region of the tower adapter.
- the tower adapter is formed in at least two parts.
- the tower adapter in this case comprises a first and a second partial element, which are connected to one another at a joint and between which an adjusting element is arranged, the joint being arranged on the convex side of the tower adapter.
- the tower adapter can thus be expanded. When in use, it has a widely protruding arch or clasp shape in order to reach back over the assemblies on the bogie. In the transport position, a somewhat stretched or largely stretched position of the upper end region can then be set, so that it is possible to lower the tower adapter as much as possible and at the same time to place the extension arm on the convex outside of the tower adapter for transport.
- the cantilever arm is formed from at least two partial arms which are connected to one another at an articulation axis.
- the center of gravity can be influenced favorably even in complex work situations.
- An adjusting element is preferably arranged between the tower adapter and the extension arm, which extends to the convex side of the tower adapter, that is to say between the tower adapter and the extension arm, when these are lowered for transport and placed against one another.
- the second pivot axis is preferably at the end of the tower adapter, so that nothing protrudes beyond the pivot axis during transport.
- the object of the invention is also achieved by a complete mobile height access machine with the features of claim 15. This is in particular provided with a work basket or crane attachment at the end of the boom unit and is thus designed as an aerial work platform.
- the height access machine according to claim 17 is based on a walking excavator chassis.
- This is characterized by extreme off-road mobility, so that the use of height access machines, especially in the form of aerial work platforms, is also possible in areas that were previously inaccessible to conventional work platforms, for example when maintaining electricity pylons or cable car systems in the mountains.
- a truck chassis as the chassis for the height access machine according to claim 17.
- the tower adapter can then not only pass over the obstacles arranged directly on the turntable. Rather, the pivot axis on which the actual cantilever arm attaches can rather be positioned overall at a greater height in this way, so that the cantilever arm can then also work beyond the truck cab.
- the height access boom unit according to the invention is advantageously used on a chassis of a walking excavator undercarriage or truck.
- the 1 to 3 show an embodiment of a mobile height access machine in the form of a walking excavator with an aerial work platform 100 in one of many possible working positions in a side view.
- the aerial work platform 100 in the embodiment of FIG 1 to 3 the essential assemblies are a chassis 10, a rotating tower 20, a cantilever arm 30 with a work cage 50 attached to the end, and a tower adapter 40 between the rotating tower 20 and the cantilever arm 30.
- Tower adapter 40, boom arm 30 and work basket 50 form the so-called height access boom unit, which as a whole can be mounted on the chassis 10 with the rotating tower 20 mounted thereon.
- the chassis 10 is in the illustrated embodiment of the 1 to 3 designed as a walking excavator undercarriage.
- the chassis 10 comprises four stepping legs 12 which can be adjusted independently of one another in lateral position and height, on each of which a wheel 11 and a mountain support 13 are attached.
- the wheels 11 are preferably individually driven by hydraulic motors. In the 1 to 3 the front wheels 11 are on the right and the rear wheels 11 are on the left.
- the walking legs 12 can be spread apart laterally from the chassis 10 and the inclination in the vertical direction relative to the chassis 10 is adjustable, so that the chassis can not only be moved over the wheels 11, but can even climb over obstacles such as boulders.
- the chassis 10 also allows support on steep slopes.
- the mountain support 13 serves to securely support the chassis 10 on slopes.
- the turret 20 is mounted on the chassis 10 and is designed to be rotatable about a vertical or substantially vertical axis of rotation 21.
- the turret 20 has an operator cabin 23 and a motor housing 22 in which hydraulic or pneumatic units, control units, etc. are also arranged.
- a first, horizontally or essentially horizontally extending pivot axis 43 is arranged in the periphery of the turret 20, that is to say outside or clearly outside the axis of rotation 21, although not necessarily exactly on the outer edge of the turret 20, a first, horizontally or essentially horizontally extending pivot axis 43 is arranged.
- the tower adapter 40 is connected to the rotating tower 20 via the pivot axis 43.
- the tower adapter 40 is connected to the extension arm 30 by means of a second pivot axis 44, which runs horizontally or essentially horizontally.
- the tower adapter 40 has a strong curvature in a lower end region 41, approximately between the pivot axis 43 and a central region.
- the lower end region 41 of the tower adapter 40 is configured in the region of the pivot axis 43 or adjacent to it or adjacent to it essentially in the form of an arc, bent, curved, cranked or the like in the form of a clasp.
- the (approximately) concave side of the arch-shaped, curved, curved, cranked or similar clasp-shaped tower adapter 40 faces the turret 20 or the vertically or substantially vertically extending axis of rotation 21 of the turret 20 or faces the center of the turret 20 the approximately convex side therefore faces away from the turret 20.
- a middle region of the tower adapter 40 adjoins the lower end region 41.
- the central region of the tower adapter 40 is essentially elongated and points in the in the 1 to 3 shown embodiment has a less pronounced curvature than the lower end region 41.
- An upper end region 42 of the tower adapter 40 adjoins the central region. In the upper end region 42 of the tower adapter 40, approximately between the central region and the pivot axis 44, the tower adapter 40 protrudes far, preferably as far as above the operator's cab 23.
- the tower adapter 40 has according to that in FIGS 1 to 3 illustrated embodiment approximately between the central region and the pivot axis 44 a slightly counter-rotating, outwardly projecting shape.
- the upper end region 42 of the tower adapter 40 in the region of the pivot axis 44 or adjacent to it or adjacent to it is also essentially arcuate, bent, curved, cranked or the like in the form of a clasp.
- the curvature of the upper end region 42 runs in a very preferred manner opposite to that of the lower end region 41.
- the second pivot axis 45 comes into an exposed position, so that the mobility of the extension arm 30 on the pivot axis 45 is increased.
- the tower adapter 40 is thus essentially S-shaped. Its center of gravity is therefore preferably in the region of and / or parallel to the axis of rotation 21 of the turret 20.
- the middle region of the tower adapter 40 in the working position runs approximately vertically and essentially parallel to the axis of rotation 21 of the turret 20.
- the end region 42 lies essentially above the axis of rotation 21 and the operator's cab 23.
- the possible one falls fictitious focus of the end area 42 of the tower adapter 40 together with the axis of rotation 20 of the turret 20.
- the design of the extension arm 30 with an upper arm 31 and a forearm 32 and an intermediate articulated joint 33 is known per se from aerial work platforms.
- the upper arm 31 and / or the forearm 32 can be extendable with telescopic elements 36.
- the work basket 50 is connected via an axis 37.
- the upper arm 31 is raised by means of a hydraulic or pneumatic cylinder 34.
- the angle between the upper arm 31 and the forearm 32 can be adjusted by means of a hydraulic or pneumatic cylinder 38.
- the Fig. 1 shows the working position of the height access boom unit according to the invention. It can be clearly seen that in the working position of the height access boom unit according to the invention, the arm boom 30 operates with the work basket 50 in the rear region of the turret 20 or the axis of rotation 21, namely on the side facing away from the operator cabin 23. Since the height access boom unit is operated remotely from the work basket 50, this does not represent a disadvantage. The operator cabin 23 is only required for maneuvering and for road transport.
- An additional, essential advantage lies in the fact that the axis of rotation 21 of the rotating tower 20 in the working position essentially runs or is arranged between the tower adapter 40 and the working basket 50.
- no parts protrude into the rear work area.
- the mobile aerial work platform 100 can be set up very close to a wall with its walking leg 12, a pivoting of the extension arm 30 by at least 90 ° to either side is nevertheless possible.
- the Fig. 2 shows the transport position of the height access boom unit according to the invention. All legs 12 are drawn close to the chassis 10. The mountain supports 13 are pivoted up. The turret 20 is aligned and secured in the longitudinal direction of the chassis 10 in such a way that the extension arm 30 extends essentially parallel to the direction of travel. The tower adapter 40 is pivoted backwards and downwards as far as possible about the first pivot axis 43 and rests on a support on the turret 20. The cantilever arm 30 is folded in with its two parts 31, 32, namely pivoted maximally forwards and downwards about the second pivot axis 44 and in turn lies on the tower adapter 40. All telescopic elements 36 are retracted so that the work basket 50 is positioned as close as possible to the turret 20.
- the tower adapter 40 is preferably formed at least in two parts. In this way, the tower adapter 40 can be expanded in the transport position.
- the at least two sub-elements of the tower adapter 40 are rotatably connected to one another via a joint 45 or the like axis of rotation and can be actuated or rotated relative to one another via an adjusting element 46, for example in the form of a hydraulic or pneumatic cylinder.
- the joint 45 is preferably arranged on the essentially convex-shaped side of the tower adapter 40, while the adjusting element 46 is arranged and effective on the essentially concave-shaped side of the tower adapter 40.
- the upper end region 42 with the pivot axis 44 for connecting the extension arm 30 around the joint 45 from the central region and the lower, clip-shaped end section 41 of the tower adapter 40 are moved away.
- the pivot axis 44 is arranged clearly above the almost horizontal, central region of the tower adapter 40, which in turn enables the cantilever arm 30 itself to be mounted horizontally. In this way, a very compact configuration of the aerial work platform 100 in terms of height and length is achieved for road transport.
- the tower adapter 40 preferably has a length such that the distance between the pivot axes 43, 44 is approximately 0.3 times to approximately 0.7 times, in particular approximately 0.4 times to approximately 0, 6 times, the length of the cantilever arm is 30. In the event that the aerial work platform 100 is transported with the work basket 50 removed, the length of the tower adapter 40 is to be selected such that the center of the height access boom unit and the axis of rotation 21 essentially coincide.
- the Fig. 3 finally shows an intermediate position of the height access boom unit according to the invention.
- the tower adapter 40 is already rotated about 90 ° about the pivot axis 43 and raised upwards.
- the spreading between the sub-elements of the tower adapter 40 has been reduced.
- the two sub-elements of the tower adapter 40 are again in contact with one another, are supported on one another and form a continuous clasp of preferably any S-shaped shape.
- the cantilever arm 30, on the other hand, is still in a horizontal position, but can be brought directly into many other working positions from this position.
- the increased arrangement of the lower bearing for the extension arm 30 on the pivot axis 44 due to the tower adapter 40 has the additional advantage that over adjacent obstacles on the ground, such as parking Cars that can be worked away. A pivoting of the turret 20 is still possible even on a slope indicated by the dashed lines.
- the present invention is not limited to the illustrated embodiment. It is thus readily possible to provide a crane and / or tool or similar attachment instead of a work cage 50. Furthermore, it is entirely conceivable that the parting plane of the two sub-elements of the tower adapter 40 is not provided between the upper end region 42 and the central region, but at another location, for example approximately exactly in the central region or also between the central region and the lower end region 41 . Finally, it is also possible to design the tower adapter 40 not in two but in several parts.

Description
Die Erfindung betrifft eine Höhenzugang-Auslegereinheit für eine mobile Höhenzugangsmaschine, eine Höhenzugangsmaschine und eine Verwendung der Höhenzugang-Auslegereinheit.The invention relates to a height access boom unit for a mobile height access machine, a height access machine and a use of the height access boom unit.
Für Arbeiten in der Höhe, wie Baumarbeiten, Fassadenarbeiten oder Instandsetzungs- oder Reinigungsarbeiten im Inneren von Hallen, Kirchen und anderen großen Gebäuden, aber auch für die Wartung von Strommasten, Windkraftanlagen oder Steilhangsicherungen, sind Höhenzugangsmaschinen in Form von Hubarbeitsbühnen bekannt, die eine Höhenzugang-Auslegereinheit der eingangs genannten Art besitzen. Größe und Kinematik des Auslegerarms sind dabei dem notwendigen Arbeitsraum angepasst. Insbesondere kommt dabei ein sogenannter Knickarmausleger zum Einsatz, d.h. ein zweiteiliger Auslegerarm, bei dem der Winkel zwischen Unter- und Oberarm veränderbar ist. Eine Teleskopausbildung an einem oder beiden Teilarmen vergrößert den Arbeitsbereich zusätzlich. Anstelle des Arbeitskorbes kann ein Kranaufsatz montiert werden, um Lasten in der Höhe versetzen zu können.For work at height, such as tree work, facade work or repair or cleaning work inside halls, churches and other large buildings, but also for the maintenance of electricity pylons, wind turbines or steep slope protection, height access machines in the form of aerial work platforms are known which provide height access. Have boom unit of the type mentioned. The size and kinematics of the extension arm are adapted to the necessary work area. In particular, a so-called articulated arm boom is used, i.e. a two-part extension arm, in which the angle between the forearm and upper arm can be changed A telescope design on one or both arms also increases the work area. A crane attachment can be installed in place of the work basket in order to be able to move loads at height.
Am Chassis sind oftmals ausfahrbare Stützen erforderlich, um im Arbeitseinsatz mit dem Arbeitskorb bzw. dem Kranaufsatz möglichst weit nach außen reichende Positionen zu erreichen und Standsicherheit zu gewährleisten. Das Stützensystem benötigt Überwachungssensoren, einen meist hydraulischen Antrieb und ein Steuerungssystem. Soll das Chassis selbstständig verfahrbar sein, wird ein Antrieb benötigt. Auch ist stets ein Drehturm vorgesehen, auf dem die Höhenzugang-Auslegereinheit montiert ist, um ohne Rangieren des Chassis schnell variierende Arbeitspositionen anfahren zu können. Zudem müssen Kontergewichte, Antriebsmotoren und Bedienelemente vorgesehen werden, um die verschiedenen Stellelemente an der Höhenzugang-Auslegereinheit bedienen zu können. Neben der für den Höhenzugang angepassten Höhenzugang-Auslegereinheit ist also ein Chassis mit den zahlreichen Baugruppen erforderlich, dessen Konstruktion und Fertigung aufwendig ist, das aber mit den genannten grundsätzlichen Funktionen auch bei anderen Arbeitsmaschinen, wie beispielsweise Baggern, in vielfältiger Weise verfügbar ist.Extendable supports are often required on the chassis in order to reach positions that extend as far out as possible with the work basket or the crane attachment and to ensure stability. The support system requires monitoring sensors, a mostly hydraulic drive and a control system. A drive is required if the chassis can be moved independently. A rotating tower is also always provided, on which the height access boom unit is mounted in order to vary quickly without having to maneuver the chassis To be able to move to work positions. In addition, counterweights, drive motors and operating elements must be provided in order to be able to operate the various adjusting elements on the height access boom unit. In addition to the height access boom unit adapted for height access, a chassis with the numerous assemblies is therefore required, the construction and manufacture of which is complex, but which is also available in a variety of ways with other work machines, such as excavators, with the basic functions mentioned.
Die Montage einer bekannten Höhenzugang-Auslegereinheit auf einem Baggerchassis wäre zwar kostengünstig, da auf Chassis von handelsüblichen Arbeitsmaschinen zurückgegriffen werden könnte, ist aber nicht direkt umsetzbar, weil die untere Schwenkachse für einen Baggerarm an der Peripherie des Drehturms angeordnet ist, denn die übrige Fläche des Drehturms ist beispielsweise mit einem Motorgehäuse, einem Gegengewicht und/oder einer Bedienerkabine überdeckt. Würde man eine Höhenzugang-Auslegereinheit anstelle eines Baggerarms an einem Baggerfahrgestell bzw. an dessen Drehturm montieren, würde zum einen im Arbeitseinsatz der Schwerpunkt des Auslegers zu weit nach außen wandern, und zum anderen wäre in der Transportstellung die große Länge der Einheit aus Baggerfahrgestell und abgesenktem Auslegerarm hinderlich, gerade bei Arbeiten dicht an Objekten oder in Gebäuden.The installation of a known height access boom unit on an excavator chassis would be cost-effective, since chassis from commercially available machines could be used, but cannot be implemented directly because the lower pivot axis for an excavator arm is arranged on the periphery of the turret, because the remaining area of the Turret is covered, for example, with a motor housing, a counterweight and / or an operator's cabin. If one were to mount a height access boom unit instead of an excavator arm on an excavator chassis or on its turret, on the one hand the center of gravity of the boom would move too far in the field of work, and on the other hand, in the transport position, the long length of the excavator chassis and lowered unit would be Boom arm is a hindrance, especially when working close to objects or in buildings.
Solche Probleme ergeben sich gleichermaßen, wenn die Höhenzugang-Auslegereinheit keinen Arbeitskorb trägt, sondern mit einem Kranaufsatz versehen ist, oder wenn als Chassis ein Lkw-Fahrgestell verwendet wird. Stets ist es erforderlich, den Schwerpunkt der Auslegereinheit möglichst nah an der Drehachse positionieren zu können, um die gegebene Abstützfläche ausnutzen zu können und jederzeit eine Standsicherheit der Höhenzugangsmaschine zu gewährleisten.Such problems arise equally if the height access boom unit does not carry a work cage but is provided with a crane attachment, or if a truck chassis is used as the chassis. It is always necessary to be able to position the center of gravity of the boom unit as close as possible to the axis of rotation in order to be able to use the given support surface and to ensure the stability of the height access machine at all times.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Höhenzugang-Auslegereinheit zur Verfügung zu stellen, mit welcher sich die obigen Nachteile verhindern lassen, welche mithin konstruktiv besonders einfach, zugleich kompakt und stabil ist sowie im Gebrauch besonders vielseitig einsetzbar ist und eine ausgesprochen hohe Standsicherheit aufweist, und eine mobile Höhenzugangsmaschine sowie deren Verwendung bereitzustellen.The present invention is therefore based on the object of providing a height access boom unit with which the above disadvantages can be prevented, which is therefore structurally particularly simple, at the same time compact and stable and can be used in a particularly versatile manner and is extremely stable has, and to provide a mobile height access machine and its use.
Diese Aufgabe wird in vorrichtungstechnischer Hinsicht auf überraschend einfache Weise durch die Merkmale des Anspruchs 1 gelöst.This task is based on device technology Solved surprisingly simple by the features of claim 1.
Die erfindungsgemäße Lösung basiert im Wesentlichen darauf, zwischen dem Drehturm und dem Auslegerarm einen beweglichen Turmadapter anzuordnen, der in irgendeiner Weise bogenförmig, gebogen, gekrümmt, gekröpft oder dergleichen spangenförmig ausgebildet ist, wobei die (etwa) konkave Seite des bogenförmig, gebogen, gekrümmt, gekröpft oder dergleichen spangenförmig ausgebildeten Turmadapters dem Drehturm bzw. der vertikal oder im Wesentlichen vertikal verlaufenden Drehachse des Drehturms zugewandt ist bzw. zum Zentrum des Drehturms weist, während die etwa konvexe Seite vom Drehturm abgewandt ist. Der erfindungsgemäße Turmadapter erstreckt sich also nicht auf einer geraden Verbindungslinie zwischen der oberen und der unteren Schwenkachse, sondern verläuft zu einem großen Teil außerhalb einer gedacht geraden Verbindungslinie gekrümmt dazu.The solution according to the invention is essentially based on arranging a movable tower adapter between the rotating tower and the cantilever arm, which is designed in any way arc-shaped, curved, curved, cranked or the like in the form of a clasp, the (approximately) concave side of the arc-shaped, curved, curved, cranked or the like clasp-shaped tower adapter faces the turret or the vertical or substantially vertical axis of rotation of the turret or faces the center of the turret, while the approximately convex side faces away from the turret. The tower adapter according to the invention therefore does not extend on a straight connecting line between the upper and the lower pivot axis, but rather extends to a large extent outside of a straight connecting line that is intended to be curved.
Mit dem Turmadapter werden wesentliche Vorteile erzielt: Durch seinen gewinkelten, gekröpften oder gekrümmten Verlauf greift der Turmadapter quasi um die auf dem Drehturm im Bereich der Drehachse platzierten Einheiten, wie Motorgehäuse, Bedienerplatz usw., herum. Dadurch kann der Turmadapter viel steiler angestellt werden als beispielsweise der Oberarm eines Baggerarms. Der Turmadapter greift also um die Hindernisse auf dem Drehturm herum. Zudem wird sein Endbereich, der die zweite, obere Schwenkachse trägt, an welcher der Auslegerarm ansetzt, oberhalb des Drehturms positioniert, insbesondere oberhalb der Drehachse. Es ist sogar möglich, die zweite Schwenkachse über die rückwärtige Seite des Drehturms hinaus an der gegenüberliegenden peripheren Seite zu positionieren. Hierdurch kann der Schwerpunkt des Gesamtsystems günstiger positioniert werden. Dadurch lässt sich die Stabilität einer Hubarbeitsbühne noch zusätzlich zu erhöhen. Auf diese Weise ist es unter anderem sogar möglich, eine Hubarbeitsbühne mit bereits teilweise ausgefahrener Höhenzugang-Auslegereinheit sicher und ohne Gefahr einer Kippinstabilität zu verfahren. Der hochgestellte Turmadapter vergrößert außerdem die Arbeitshöhe des Auslegerarms. Schließlich ist aufgrund der Anordnung und Ausbildung des erfindungsgemäßen Turmadapters von zusätzlichem Vorteil, dass über benachbarte Hindernisse am Boden, wie parkende Autos, selbst bei noch nicht ausgefahrener Höhenzugang-Auslegereinheit hinweg gearbeitet werden kann und der Drehturm selbst in unmittelbarer Nähe von Hauswänden, Hanglagen etc. kollisionsfrei (ver-)schwenkbar ist.Significant advantages are achieved with the tower adapter: Thanks to its angled, cranked or curved course, the tower adapter virtually engages around the units, such as motor housing, operator station, etc., placed on the rotating tower in the area of the axis of rotation. This allows the tower adapter to be set much steeper than, for example, the upper arm of an excavator arm. The tower adapter therefore reaches around the obstacles on the rotating tower. In addition, its end region, which carries the second, upper pivot axis on which the cantilever arm attaches, is positioned above the turret, in particular above the axis of rotation. It is even possible to position the second pivot axis beyond the rear side of the turret on the opposite peripheral side. This allows the center of gravity of the overall system to be positioned more favorably. This can further increase the stability of an aerial work platform. In this way, it is even possible, among other things, to move an aerial work platform with the boom access boom unit already partially extended, safely and without risk of tipping instability. The superscript Tower adapter also increases the working height of the boom arm. Finally, due to the arrangement and design of the tower adapter according to the invention, it is of additional advantage that work can be carried out over adjacent obstacles on the ground, such as parked cars, even when the height access boom unit has not yet been extended, and the rotating tower itself in the immediate vicinity of house walls, slopes, etc. is pivotable without collision.
Vorteilhafte konstruktive Einzelheiten der erfindungsgemäßen Höhenzugang-Auslegereinheit sind in den Ansprüchen 2 bis 13 beschrieben.Advantageous structural details of the height access boom unit according to the invention are described in claims 2 to 13.
Von ausgesprochen großer Bedeutung sind die Maßnahmen des Anspruchs 4. Danach ist der obere Endbereich des Turmadapters mit einer Bogenform, Biegung, Krümmung, Kröpfung oder dergleichen Spange versehen, welche zu der Bogenform, Biegung, Krümmung, Kröpfung oder dergleichen Spange des unteren Endbereichs des Turmadapters entgegengesetzt ausgebildet ist. Der Turmadapter erhält auf diese Weise eine bevorzugt etwa S-förmige Gestalt. Dies wiederum ermöglicht, dass sich der Endbereich des Turmadapters in der Arbeitsstellung und einer Zwischenstellung im Wesentlichen oberhalb der Drehachse und der Bedienerkabine etc. befindet. In kumulativer oder alternativer Ausgestaltung kann der obere Endbereich des Turmadapters von geringerer Ausprägung als die Ausprägung des unteren Endbereichs des Turmadapters sein.The measures of claim 4 are of extremely great importance. According to this, the upper end region of the tower adapter is provided with an arch shape, bend, curvature, cranking or the like clasp, which leads to the arch shape, bend, curvature, cranking or similar clasp of the lower end region of the tower adapter is formed in the opposite direction. In this way, the tower adapter is given an approximately S-shaped configuration. This in turn enables the end region of the tower adapter to be in the working position and an intermediate position essentially above the axis of rotation and the operator's cabin etc. In a cumulative or alternative embodiment, the upper end region of the tower adapter can be of a lesser configuration than the configuration of the lower end region of the tower adapter.
Eine bevorzugte Ausführungsform sieht vor, dass der Turmadapter nach Anspruch 7 wenigstens zweiteilig ausgebildet ist. Der Turmadapter umfasst dabei ein erstes und ein zweites Teilelement, die an einem Gelenk miteinander verbunden sind und zwischen denen ein Verstellelement angeordnet ist, wobei das Gelenk an der konvexen Seite des Turmadapters angeordnet ist. Der Turmadapter ist damit aufspreizbar. Im Arbeitseinsatz besitzt er eine weit ausladende Bogen- oder Spangenform, um über die Baugruppen auf dem Drehgestell hinweg nach hinten zu reichen. In der Transportposition kann dann eine etwas gestrecktere bzw. weitgehend gestreckte Lage des oberen Endbereichs eingestellt werden, so dass es möglich wird, den Turmadapter maximal abzusenken und zugleich den Auslegerarm auf der konvexen Außenseite des Turmadapters für den Transport abzulegen.A preferred embodiment provides that the tower adapter is formed in at least two parts. The tower adapter in this case comprises a first and a second partial element, which are connected to one another at a joint and between which an adjusting element is arranged, the joint being arranged on the convex side of the tower adapter. The tower adapter can thus be expanded. When in use, it has a widely protruding arch or clasp shape in order to reach back over the assemblies on the bogie. In the transport position, a somewhat stretched or largely stretched position of the upper end region can then be set, so that it is possible to lower the tower adapter as much as possible and at the same time to place the extension arm on the convex outside of the tower adapter for transport.
Vorteilhaft ist, wenn der Auslegerarm entsprechend den Merkmalen des Anspruchs 12 aus wenigstens zwei Teilarmen gebildet ist, die an einer Knickachse miteinander verbunden sind. Im Zusammenspiel mit der Stellung des Turmadapters kann der Schwerpunkt auch in komplexen Arbeitssituation gĂĽnstig beeinflusst werden.It is advantageous if the cantilever arm is formed from at least two partial arms which are connected to one another at an articulation axis. In combination with the position of the tower adapter, the center of gravity can be influenced favorably even in complex work situations.
Vorzugsweise ist zwischen dem Turmadapter und dem Auslegerarm ein Verstellelement angeordnet, das sich zur konvexen Seite des Turmadapters erstreckt, also zwischen dem Turmadapter und dem Auslegerarm liegt, wenn diese zum Transport abgesenkt und aneinander angelegt werden. Die zweite Schwenkachse liegt dabei vorzugweise am Ende des Turmadapters, so dass beim Transport jenseits der Schwenkachse nichts mehr hervorragt.An adjusting element is preferably arranged between the tower adapter and the extension arm, which extends to the convex side of the tower adapter, that is to say between the tower adapter and the extension arm, when these are lowered for transport and placed against one another. The second pivot axis is preferably at the end of the tower adapter, so that nothing protrudes beyond the pivot axis during transport.
Neben der zur Nachrüstung vorhandener Arbeitsmaschinen-Fahrgestelle vorgesehenen, erfindungsgemäßen Höhenzugang-Auslegereinheit wird die Aufgabe der Erfindung auch durch eine komplette mobile Höhenzugangsmaschine mit den Merkmalen des Anspruchs 15 gelöst. Dieses ist insbesondere mit einem Arbeitskorb oder Kranaufsatz am Ende der Auslegereinheit versehen und somit als Hubarbeitsbühne ausgestaltet.In addition to the height access boom unit according to the invention provided for retrofitting existing work machine chassis, the object of the invention is also achieved by a complete mobile height access machine with the features of claim 15. This is in particular provided with a work basket or crane attachment at the end of the boom unit and is thus designed as an aerial work platform.
Vorzugsweise baut die Höhenzugangsmaschine nach Anspruch 17 auf einem Schreitbagger-Chassis auf. Dieses zeichnet sich durch eine extreme Geländegängigkeit aus, so dass ein Einsatz von Höhenzugangsmaschinen, insbesondere in Form von Hubarbeitsbühnen, auch in Bereichen möglich wird, die für herkömmliche Arbeitsbühnen bisher unzugänglich waren, beispielweise bei der Wartung von Strommasten oder Seilbahnanlagen im Gebirge.Preferably, the height access machine according to claim 17 is based on a walking excavator chassis. This is characterized by extreme off-road mobility, so that the use of height access machines, especially in the form of aerial work platforms, is also possible in areas that were previously inaccessible to conventional work platforms, for example when maintaining electricity pylons or cable car systems in the mountains.
In alternativer Ausgestaltung dazu liegt es ebenso im Rahmen der Erfindung, als Fahrgestell für die Höhenzugangsmaschine nach Anspruch 17 ein Lkw-Fahrgestell vorzusehen. Hierbei kann der Turmadapter dann nicht nur über die unmittelbar auf dem Drehteller angeordneten Hindernisse hinwegreifen. Vielmehr kann auf diese Weise die Schwenkachse, an der der eigentliche Auslegerarm ansetzt, insgesamt in einer größeren Höhe positioniert werden, so dass der Auslegerarm dann auch zusätzlich über das Lkw-Fahrerhaus hinweg arbeiten kann.In an alternative embodiment, it is also within the scope of the invention to provide a truck chassis as the chassis for the height access machine according to claim 17. The tower adapter can then not only pass over the obstacles arranged directly on the turntable. Rather, the pivot axis on which the actual cantilever arm attaches can rather be positioned overall at a greater height in this way, so that the cantilever arm can then also work beyond the truck cab.
Diese Aufgabe wird schließlich noch in verwendungsmäßiger Hinsicht durch die Merkmale des Anspruchs 18 gelöst.This object is finally solved in terms of use by the features of claim 18.
Demnach findet die erfindungsgemäße Höhenzugang-Auslegereinheit in vorteilhafter Weise auf einem Chassis eines Schreitbagger-Unterwagens oder Lastkraftwagens Verwendung.Accordingly, the height access boom unit according to the invention is advantageously used on a chassis of a walking excavator undercarriage or truck.

Die
Turmadapter 40, Auslegerarm 30 und Arbeitskorb 50 bilden die sogenannte Höhenzugang-Auslegereinheit, die als Ganzes an dem Chassis 10 mit dem darauf gelagerten Drehturm 20 montierbar ist.
Das Chassis 10 ist bei dem dargestellten AusfĂĽhrungsbeispiel der
Die Schreitbeine 12 sind sowohl seitlich vom Chassis 10 abspreizbar als auch in der Neigung in der Senkrechten gegenüber dem Chassis 10 verstellbar, so dass das Chassis nicht nur über die Räder 11 verfahrbar ist, sondern sogar über Hindernisse, wie Felsbrocken, hinwegsteigen kann. Außerdem erlaubt das Chassis 10 die Abstützung an Steilhängen. Die Bergstütze 13 dient der sicheren Abstützung des Chassis 10 in Hanglagen.The walking
Auf dem Chassis 10 ist der Drehturm 20 gelagert, der um eine vertikal oder im Wesentlichen vertikal verlaufende Drehachse 21 drehbar ausgebildet ist. Der Drehturm 20 besitzt eine Bedienerkabine 23 und ein Motorgehäuse 22, in dem auch Hydraulik- oder Pneumatikaggregate, Steuerungseinheiten usw. angeordnet sind. In der Peripherie des Drehturms 20, also außerhalb oder deutlich außerhalb der Drehachse 21, wenn auch nicht zwangsläufig genau am Außenrand des Drehturms 20, ist eine erste, horizontal oder im Wesentlichen horizontal verlaufende Schwenkachse 43 angeordnet. Über die Schwenkachse 43 ist der Turmadapter 40 mit dem Drehturm 20 verbunden. Mittels einer zweiten, horizontal oder im Wesentlichen horizontal verlaufenden Schwenkachse 44 ist der Turmadapter 40 mit dem Auslegerarm 30 verbunden.The
Der Turmadapter 40 besitzt in einem unteren Endbereich 41 etwa zwischen der Schwenkachse 43 und einem mittleren Bereich eine starke Krümmung. Mit anderen Worten ist der untere Endbereich 41 des Turmadapters 40 im Bereich der Schwenkachse 43 bzw. zu dieser benachbart bzw. an dieser angrenzend im Wesentlichen bogenförmig, gebogen, gekrümmt, gekröpft oder dergleichen spangenförmig ausgestaltet. Die (etwa) konkave Seite des bogenförmig, gebogen, gekrümmt, gekröpft oder dergleichen spangenförmig ausgebildeten Turmadapters 40 ist dabei dem Drehturm 20 bzw. der vertikal oder im Wesentlichen vertikal verlaufenden Drehachse 21 des Drehturms 20 zugewandt bzw. weist zum Zentrum des Drehturms 20. Die etwa konvexe Seite ist mithin vom Drehturm 20 abgewandt.The
An den unteren Endbereich 41 schlieĂźt sich ein mittlerer Bereich des Turmadapters 40 an. Der mittlere Bereich des Turmadapters 40 ist im Wesentlichen langestreckt und weist bei der in den
An den mittleren Bereich schlieĂźt sich ein oberer Endbereich 42 des Turmadapters 40 an. In dem oberen Endbereich 42 des Turmadapters 40 etwa zwischen dem mittleren Bereich und der Schwenkachse 44 ragt der Turmadapter 40 weit, bevorzugt bis ĂĽber die Bedienerkabine 23, vor.An
Im oberen Endbereich 42 besitzt der Turmadapter 40 gemäß dem in den
Ohne im Einzelnen dargestellt zu sein, ist es jedoch ebenso denkbar, den oberen Endbereich 42 des Turmadapters 40 auch ohne jede KrĂĽmmung und damit geradlinig auszubilden.Without being shown in detail, however, it is also conceivable to design the
Wie der
Die Ausbildung des Auslegerarms 30 mit einem Oberarm 31 und einem Unterarm 32 sowie einem dazwischenliegenden Knickgelenk 33 ist an sich von Hubarbeitsbühnen bekannt. Der Oberarm 31 und/oder der Unterarm 32 kann/können mit Teleskopelementen 36 verlängerbar sein. Am Ende des Armauslegers 30 ist der Arbeitskorb 50 über eine Achse 37 angebunden. Das Anheben des Oberarms 31 erfolgt über einen Hydraulik- oder Pneumatikzylinder 34. Der Winkel zwischen dem Oberarm 31 und dem Unterarm 32 ist über einen Hydraulik- oder Pneumatikzylinder 38 einstellbar.The design of the
Die
Ein zusätzlicher, wesentlicher Vorteil liegt darin, dass die Drehachse 21 des Drehturms 20 in der Arbeitsposition im Wesentlichen zwischen Turmadapter 40 und Arbeitskorb 50 verläuft bzw. angeordnet ist. Der Turmadapter 40 mit seinem Eigengewicht, der auf der vom Arbeitskorb 50 abgewandten Seite der Drehachse 21 positioniert ist, wirkt damit als Gegengewicht zu den durch den Arbeitskorb 50 erzeugten Kräften und daraus resultierenden Momenten und gleicht daher die Masse des am Drehturm 20 fest installierten Kontergewichts am Heck aus. Außerdem ragen keinerlei Teile in den rückwärtigen Arbeitsraum. Die mobile Hubarbeitsbühne 100 kann auf diese Weise mit ihrem Schreitbein 12 ganz dicht an einer Wand aufgestellt werden, wobei dennoch ein Schwenken des Auslegerarms 30 um wenigstens 90° zu jeder Seite möglich ist.An additional, essential advantage lies in the fact that the axis of

Die wenigstens zwei Teilelemente des Turmadapters 40 sind über ein Gelenk 45 oder dergleichen Drehachse miteinander drehbar verbunden und über ein Verstellelement 46, zum Beispiel in Form eines Hydraulik- oder Pneumatikzylinders, betätigbar bzw. zueinander relativ verdrehbar. Vorzugsweise ist das Gelenk 45 auf der im Wesentlichen konvex geformten Seite des Turmadapters 40 angeordnet, während das Verstellelement 46 auf der im Wesentlichen konkav geformten Seite des Turmadapters 40 angeordnet und wirksam ist.The at least two sub-elements of the

Zudem ist die Stellung gut ausbalanciert, da sich die Mitte der Längserstreckung des Auslegerarms 30 im Wesentlichen zwischen dem Knickgelenk 33 und dem Arbeitskorb 50 auf Höhe der Drehachse 21 befindet. Um dies zu erreichen, besitzt der Turmadapter 40 vorzugsweise eine solche Länge, dass der Abstand zwischen den Schwenkachsen 43, 44 das etwa 0,3-Fache bis etwa 0,7-Fache, insbesondere das etwa 0,4-Fache bis etwa 0,6-Fache, der Länge des Auslegerarms 30 beträgt. Für den Fall, die Hubarbeitsbühne 100 mit demontiertem Arbeitskorb 50 zu transportieren, ist die Länge des Turmadapters 40 derart zu wählen, dass die Mitte der Höhenzugang-Auslegereinheit und die Drehachse 21 im Wesentlichen zusammenfallen.In addition, the position is well balanced since the middle of the longitudinal extension of the

Die vorliegende Erfindung ist nicht auf die dargestellte Ausführungsform beschränkt. So ist es ohne weiteres möglich, anstelle eines Arbeitskorbes 50 gleichermaßen einen Kran- und/oder Werkzeug oder dergleichen -aufsatz vorzusehen. Des Weiteren ist es durchaus denkbar, dass die Trennebene der zwei Teilelemente des Turmadapters 40 nicht zwischen dem oberen Endbereich 42 und dem mittleren Bereich, sondern an anderer Stelle, beispielsweise etwa genau im mittleren Bereich oder auch zwischen mittlerem Bereich und unterem Endbereich 41, vorgesehen ist. Schließlich ist es auch möglich, den Turmadapter 40 nicht zwei-, sondern mehrteilig auszubilden.The present invention is not limited to the illustrated embodiment. It is thus readily possible to provide a crane and / or tool or similar attachment instead of a
