Darstellung der ErfindungPresentation of the invention

Es ist das technische Problem (Aufgabe) der vorliegenden Erfindung, einen Gerätekran, insbesondere einen Kamerakran, zu schaffen, mit dem durch vereinfachte technische Mittel eine Einrichtung und Einstellung des Führungssystems vorgenommen und somit die Geräte- beziehungsweise Kameraführung variabler gestaltet werden kann.It is the technical problem (object) of the present invention to provide a device crane, in particular a camera crane, with which by simplified technical means a device and setting of the guide system made and thus the device or camera operation can be made more variable.

Dieses Problem wird gelöst durch einen Gerätekran, insbesondere Kamerakran, mit einer Kranstütze und einem an einer ersten Anlenkstelle daran schwenkbar angelenkten Kranausleger, einem an einer zweiten Anlenkstelle am der Kranstütze abgewandeten einen Ende des Kranauslegers angelenkten Geräteaufnahmeelement, an dem im Abstand zur zweiten Anlenkstelle zwischen Kranausleger und Geräteaufnahmeelement an einer dritten Anlenkstelle ein Zugelement, insbesondere ein Zugseil, angelenkt ist, das von der dritten Anlenkstelle am Geräteaufnahmeelement zu einer vierten Anlenkstelle an der Kranstütze verläuft, welche vierte Anlenkstelle im Abstand zur ersten Anlenkstelle angeordnet ist, wobei die vierte Anlenkstelle verstellbar an der Kranstütze angeordnet ist, und wobei das Zugelement längenverstellbar ist. Das Zugelement ist dabei über die vierte Anlenkstelle hinaus weitergeführt und an der Kranstütze festgelegt. Dabei ist das Zugelement mit einem daran angebrachten Rastelement versehen, das an einer an der Kranstütze beweglichen Raststelle lösbar eingerastet wird.This problem is solved by a crane equipment, in particular camera crane, with a crane support and a pivotally hinged thereto at a first articulation point crane boom, a hinged at a second articulation point on the crane support one end of the crane jib articulated device receiving element at the distance to the second pivot point between the crane boom and device receiving element at a third articulation point, a tension element, in particular a traction cable is articulated, which extends from the third articulation point on the device receiving element to a fourth articulation point on the crane support, which fourth articulation point is spaced from the first articulation point, said fourth articulation point adjustable at the Crane support is arranged, and wherein the tension element is adjustable in length. The tension element is continued beyond the fourth pivot point and fixed to the crane support. In this case, the tension element is provided with a locking element attached thereto, which is releasably locked to a movable resting position on the crane support.

Dadurch besteht in einfacher Weise die Möglichkeit, zugleich durch Handhabung des weitergeführten Endes des Zugelements die Winkelstellung der Geräteaufnahmeelement einzustellen, die Länge des Zugelements anzupassen, wenn der Kranausleger als Teleskopausleger oder als anderweitig längenveränderbarer Kranausleger ausgebildet ist und eine Verstellung der vierten Anlenkstelle an der Kranstütze vorzunehmen, um entweder eine Parallelogrammführung zu realisieren oder/aber eine Führung außerhalb des Parallelogrammsystems.This makes it possible in a simple manner, at the same time adjust the angular position of the device receiving element by handling the continued end of the tension member to adjust the length of the tension member when the crane boom is designed as a telescopic boom or otherwise variable-length crane boom and make an adjustment of the fourth pivot point on the crane support in order to realize either a parallelogram guidance or / but a guidance outside the parallelogram system.

Bevorzugt ist das Zugelement an einer Klemmstelle festgelegt. Es kann auf einfache Weise die Länge des Zugelements an die jeweilige Länge eines Teleskopauslegers angepasst werden, wenn in Längsabständen mehrere solche Rastelemente am Zugelement angebracht sind.Preferably, the tension element is fixed to a nip. It can easily adjust the length of the tension element to the respective length of a telescopic boom to be adjusted when a plurality of such locking elements are attached to the tension element in longitudinal intervals.

Wenn dabei die Raststelle in Richtung des Verlaufs des Zugelements verstellbar ist, so ist über diese Festlegung des Zugelements im Bereich der Kranstütze über das Zugelement eine einfache Verstellung des Anstellwinkels des Geräteaufnahmeelements möglich.If in this case the latching point is adjustable in the direction of the course of the tension element, then a simple adjustment of the angle of attack of the device receiving element is possible via this determination of the tension element in the region of the crane support via the tension element.

Entsprechend einer vorteilhaften Ausgestaltung und im Hinblick auf eine möglichst einfache Handhabung durch die Bedienungsperson, kann auf einer Seite der Kranstütze die vierte Anlenkstelle und auf der entgegensetzten Seite desselben die Raststelle angeordnet sein.According to an advantageous embodiment and with a view to the simplest possible handling by the operator, the fourth pivot point can be arranged on one side of the crane support and on the opposite side thereof the latching point.

Hinsichtlich einer weiteren Ausgestaltung kann die vierte Anlenkstelle von einer bevorzugt drehbar gelagerten Seilscheibe gebildet sein, um die zumindest teilweise das Zugelement verläuft und von dort zur Raststelle geführt ist. Somit kann die Verstellung der vierten Anlenkstelle mit dem benötigten Anordnungsraum auf einer Seite der Kranstütze und die Verkürzung des Zugelements durch die Verstellung des Einstellwinkels auf der anderen Seite der Kranstütze vorgenommen werden.With regard to a further embodiment, the fourth articulation point can be formed by a preferably rotatably mounted sheave around which runs at least partially the tension element and is guided from there to the rest position. Thus, the adjustment of the fourth pivot point can be made with the required arrangement space on one side of the crane support and the shortening of the tension element by the adjustment of the adjustment angle on the other side of the crane support.

Für eine bevorzugte Anordnung der Verstellmöglichkeiten auf beiden Seiten der Kranstütze kann in Richtung auf die Raststelle hinter der Seilscheibe eine Umlenkscheibe für das Zugelement vorgesehen sein, deren Achse parallel zur Achse der Seilscheibe angeordnet ist, und die an der Kranstütze befestigt ist, woran sich mindestens eine weitere Umlenkscheibe anschließt, deren Achse senkrecht zur Achse der ersten Umlenkscheibe angeordnet ist, so dass das dazwischen verlaufende Zugelement tangential am Umfang beider Umlenkscheiben anliegt.For a preferred arrangement of the adjustment on both sides of the crane support may be provided in the direction of the rest behind the sheave a pulley for the tension element whose axis is arranged parallel to the axis of the sheave, and which is fixed to the crane support, what is at least one further deflection plate connects, the axis of which is arranged perpendicular to the axis of the first deflection pulley, so that the tension element extending therebetween bears tangentially on the circumference of the two deflection pulleys.

Für eine Kombination der Parallelogrammführung mit einer Führung des Zugelements außerhalb des Parallelogrammsystems ist die bevorzugte Achse der Seilscheibe an der ersten Anlenkstelle angeordnet. An dieser ersten Anlenkstelle ist der Kranausleger schwenkbar gelagert.For a combination of the parallelogram guide with a guide of the tension element outside the parallelogram system, the preferred axis of the pulley is arranged at the first articulation point. At this first pivot point of the crane boom is pivotally mounted.

Beschreibung eines AusführungsbeispielsDescription of an embodiment

Ein in Fig. 1 dargestellter Kamerakran umfasst eine Kranstütze 1, die in Fig. 1 nur teilweise dargestellt ist. Der untere Teil der Kranstütze 1 ist hier nicht dargestellt, kann aber in Form eines Tripods ausgeführt sein. Weiterhin umfasst der Kamerakran einen Kranausleger 2, der an einer ersten Anlenkstelle 3 an der Kranstütze 1 schwenkbar gelagert ist. Am in der Darstellung rechten Ende des Kranauslegers 2 befindet sich ein Gegengewicht 4. Am entgegengesetzten Ende des Kranauslegers 2 ist an einer zweiten Anlenkstelle 5 als Kameraaufnahmeelement ausgebildete Kameraaufnahmeplatte 6 schwenkbar gelagert. Zusammen schwenkbar mit der Kameraaufnahmeplatte 6 ist hier als Ausführungsbeispiel (auf das die Erfindung nicht beschränkt ist) eine Seilscheibe 7 angeordnet, deren Zentrum sich im Bereich der zweiten Anlenkstelle 5 befindet. Ohne eine Beschränkung auf dieses Ausführungsbeispiel befindet sich eine gleiche Seilscheibe 8 an der ersten Anlenkstelle 3, so dass deren Zentrum an dieser Anlenkstelle angeordnet ist, die zugleich Schwenkachse des Kranauslegers 2 ist. Zwischen diesen Scheiben 7 und 8 verläuft ein Zugseil 9 derart, dass an der tangentialen Anlaufstelle des Zugseils 9 am Umfang der Seilscheiben 7 und 8 im Bereich der Kameraaufnahmeplatte 6 eine dritte Anlenkstelle 10 und im Bereich der Schwenklagerung des Kranauslegers eine vierte Anlenkstelle 11 gebildet wird. Wenn dieses Zugseil 9, das zugleich Steuerseil ist, parallel zum Kranausleger 2 verläuft, so bildet der Kranausleger zusammen mit dem Zugseil 9 und den Anlenkstellen 3, 5, 10, 11 ein Parallelogrammsystem derart, dass beim Verschwenken des Kranauslegers 2 die Kameraaufnahmeplatte 6 entweder in einer exakt horizontal ausgerichteten Lagestellung oder aber in einer bestimmten Neigungsstellung gehalten werden kann, wenn die Kameraaufnahmeplatte 6 mittels des Kranauslegers 2 bei dessen Verschenken in der Kranstütze 1 im Raum bewegt wird.A illustrated in Fig. 1 camera crane comprises a crane support 1, which is shown only partially in Fig. 1. The lower part of the crane support 1 is not shown here, but may be designed in the form of a tripod. Furthermore, the camera crane comprises a crane jib 2, which is pivotally mounted on the crane support 1 at a first articulation point 3. At the right end of the crane jib 2 in the representation, there is a counterweight 4. At the opposite end of the crane jib 2 camera receiving plate 6 formed at a second pivot point 5 as a camera receiving element is pivotally mounted. Together pivotable with the camera receiving plate 6 is here as an exemplary embodiment (to which the invention is not limited) a pulley. 7 arranged, whose center is located in the region of the second pivot point 5. Without being limited to this exemplary embodiment, a same pulley 8 is located at the first articulation point 3, so that its center is arranged at this articulation point, which at the same time is the pivot axis of the crane boom 2. Between these discs 7 and 8, a traction cable 9 extends such that at the tangential contact point of the traction cable 9 on the circumference of the pulleys 7 and 8 in the camera receiving plate 6, a third articulation point 10 and in the region of the pivotal mounting of the crane boom, a fourth articulation point 11 is formed. If this traction cable 9, which is also a control cable, runs parallel to the crane jib 2, the crane jib together with the traction cable 9 and the articulation points 3, 5, 10, 11 forms a parallelogram system such that when the crane jib 2 is swiveled, the camera mounting plate 6 is either in a precisely horizontally aligned position or can be kept in a specific tilt position when the camera receiving plate 6 is moved by means of the crane jib 2 when it is given in the crane support 1 in space.

Der Kranausleger 2 kann dann relativ leichtgewichtig ausgeführt werden, wenn dieser durch Seilverstrebungen 12 versteift ist. Außerdem kann die Länge des Kranauslegers 2 verändert werden, in dem beispielsweise der Kranausleger teleskopierbar ist oder aber der Kranausleger 12 aus mehreren Teilstücken besteht, die in einander gesteckt sind, so dass Verkürzungen beziehungsweise Verlängerungen vorgenommen werden können. Dabei werden die Seilverstrebungen 12 entsprechend umgehängt und es wird auch das Zugseil 9 in seinem Verlauf entsprechend angepasst, d. h. verkürzt oder verlängert.The crane boom 2 can then be made relatively lightweight, if this is stiffened by cable struts 12. In addition, the length of the crane jib 2 can be changed, in which, for example, the crane boom is telescopic or crane jib 12 consists of several sections that are plugged into each other, so that shortening or extensions can be made. The cable struts 12 are accordingly relocated and it is also the pull rope 9 adapted accordingly in its course, d. H. shortened or extended.

Wenn im Zusammenhang mit der Kranauslegerlängenveränderung von einem Teleskopausleger der Rede ist, so schließt diese Ausdrucksweise auch die vorerwähnte Steckverbindung ein.If in connection with the crane boom length change of a telescopic boom of the speech, so this expression also includes the aforementioned connector.

Die Seilscheiben 7 und 8 müssen nicht, können aber drehbar sein, wobei die Seilscheibe 8 bevorzugt um ihre Achse drehbar ist. Die Seilscheibe 7 ist normalerweise mit der Kameraaufnahmeplatte drehbar.The pulleys 7 and 8 do not have to but can be rotatable, the pulley 8 is preferably rotatable about its axis. The pulley 7 is normally rotatable with the camera receiving plate.

Die in Fig. 2 isoliert dargestellte Kranstütze ohne Untergestell verdeutlicht nur einen Teil des Kranauslegers 2. Fig. 2 zeigt aber deutlicher die Einzelheiten als Fig. 1, insbesondere die Seilscheibe 8 mit der ersten Anlenkstelle 3, die in der Schwenkachse des Kranauslegers 2 liegt und die bei Einstellung des Parallelogrammsystems mit der Achse der Seilscheibe 8 zusammenhält. Deutlich erkennbar ist auch das Zugseil 9, das von der nicht dargestellten Seilscheibe 7 kommend teilweise um die Seilscheibe 8 verläuft und weitergeführt ist, wobei das Seilende an der Kranstütze 1 befestigt ist. Dies kann grundsätzlich an derselben Seite der Kranstütze vorgesehen sein. Hier befindet sich die Seilscheibe 8 auf der einen Seite der Kranstütze und das festgelegte Ende des Zugseils 9 auf der anderen Ende der Kranstütze, wobei eine Hauptteilstütze 13 und eine Nebenteilstütze 14 vorgesehen ist. Obwohl das Festlegen des Seilendes an der Kranstütze 1 auch auf derselben Seite, d. h. auf der Seite der Hauptteilstütze 13 vorgesehen sein kann, ist hier eine aufgesplittete Lösung dargestellt, bei der das Zugseil 9 teilweise um die Seilscheibe 8 geführt ist und von dort teilweise um eine Umlenkscheibe 15 geführt ist. Die Drehachse 16 dieser Umlenkscheibe 15 verläuft parallel zur Achse der Seilscheibe 8. Von der Umlenkscheibe 15 verläuft das Zugseil 9 teilweise um eine Umlenkscheibe 17, deren Achse senkrecht zur Achse 16 der Umlenkscheibe 15 umläuft. Von dort verläuft das Zugseil 9 von der Hauptteilstütze 13 zur Nebenteilstütze 14 und ist in dieser nochmals um eine weitere Umlenkscheibe 18 geführt, die auch aus Fig. 3 ersichtlich ist. Von dort verläuft das Zugseil 9 zu einem eine Raststelle bildenden Einhängelement 19. Dieses Einhängelement 19 ist in einer Aussparung 20 der Nebenteilstütze 14 verschiebbar gelagert, und zwar in einer Richtung, die dem Verlauf des Zugseils 9 an dieser Stelle entspricht. Dieses Einhängelement 19 ist hier als Spindelmutter ausgeführt und sitzt auf einer Spindelschraube 21. Wenn diese Spindelschraube 21 mittels einer Drehhandhabe 22 gedreht wird, kann das Einhängelement 19 hinsichtlich seiner Lage in Richtung der Spindelschraube 21 verändert werden. Dies hat zur Folge, dass in der entsprechenden Richtung an dem Zugseil 9 gezogen wird. Dies hat wiederum zur Folge, dass sich die Winkelstellung der Kameraaufnahmeplatte 6 verändert. Es kann also durch diese Verstellmöglichkeit die jeweils gewünschte Winkelstellung der Kameraaufnahmeplatte 6 eingestellt werden. Bei der eingestellten Parallelogrammführung über das Zugseil 9 und den Kranausleger 2 kann beim Verschwenken des Kranauslegers dann diese jeweilige Stellung beibehalten werden. Man kann allerdings auch diese Parallelogrammführung aufgeben. Hierzu ist über ein ähnliches Spindel-Mutter-System über eine Spindelschraube 23 und eine Handhabe 24 die Lage der Seilscheibe 8 in der Hauptteilstütze 13 veränderbar und zwar in etwa in derselben Richtung wie die Verstellung des Einhängelements 19, wodurch einerseits eine exakte Einstellung des Parallelogrammsystems vorgenommen werden kann, andererseits aber auch eine Verstellung dermaßen vorgenommen werden kann, dass das Zugseil 9 mehr oder weniger das Parallelogrammsystem verlässt. Bei dieser Verstellung kommt es ebenso zu einer Veränderung der Winkellage der Kameraaufnahmeplatte 6 aber auch zu einer gewünschten Einstellung der Änderung der Winkelstellung der Kameraaufnahmeplatte während des Verschwenkens des Kranauslegers.Fig. 2 shows but more clearly the details than Fig. 1, in particular the pulley 8 with the first articulation point 3, which lies in the pivot axis of the crane jib 2 and which holds together when setting the Parallelogrammsystems with the axis of the pulley 8. Clearly visible is also the pull cable 9, which extends from the pulley 7, not shown partially extending around the sheave 8 and is continued, the cable end is attached to the crane support 1. This can basically be provided on the same side of the crane support. Here, the sheave 8 is located on one side of the crane support and the fixed end of the traction cable 9 on the other end of the crane support, wherein a main part support 13 and a secondary part support 14 is provided. Although the setting of the rope end on the crane support 1 can also be provided on the same side, ie on the side of the main part support 13, here a split solution is shown in which the pull rope 9 is partially guided around the sheave 8 and from there partially to a Deflection pulley 15 is guided. The axis of rotation 16 of this deflection plate 15 extends parallel to the axis of the sheave 8. From the deflection plate 15, the traction cable 9 extends partially around a deflection plate 17, the axis of which rotates perpendicular to the axis 16 of the deflection plate 15. From there, the pull cable 9 extends from the main part support 13 to the secondary part support 14 and is guided in this again by a further deflecting plate 18, which is also apparent from Fig. 3. From there, the traction cable 9 extends to a latching point forming suspension element 19. This suspension element 19 is slidably mounted in a recess 20 of the secondary part support 14, in a direction corresponding to the course of Zugseils 9 corresponds at this point. This suspension element 19 is embodied here as a spindle nut and is seated on a spindle screw 21. When this spindle screw 21 is rotated by means of a rotary handle 22, the suspension element 19 can be changed with respect to its position in the direction of the spindle screw 21. This has the consequence that is pulled in the appropriate direction on the pull cable 9. This in turn means that the angular position of the camera receiving plate 6 changes. It can therefore be adjusted by this adjustment the respective desired angular position of the camera receiving plate 6. When set parallelogram on the traction cable 9 and the crane boom 2, then this position can be maintained during pivoting of the crane jib. However, one can also give up this parallelogram. For this purpose, the position of the sheave 8 in the main part support 13 is about a similar spindle-nut system via a screw screw 23 and a handle 24 variable in about the same direction as the adjustment of the suspension element 19, whereby on the one hand made an exact adjustment of the parallelogram On the other hand, however, an adjustment can be made so that the pull rope 9 more or less leaves the parallelogram system. In this adjustment, it also comes to a change in the angular position of the camera receiving plate 6 but also to a desired setting the change in the angular position of the camera receiving plate during pivoting of the crane boom.

Für das Einhängen des Seilendes des Zugseils 9 in dem Einhängelement 19 dient ein am Zugseil befestigtes Halte- oder Rastelement 25, das im eingehängten Zustand nicht erkennbar ist, aber durch ein im Verlauf des Zugseils 9 dargestelltes Rastelement 25, welches dann zum Tragen kommt, wenn eine Verkürzung des Kranauslegers 2 vorgenommen wird. Dann nämlich wird das Zugseil 9 über die beschriebene Umlenkeinrichtung durchgezogen und dabei das Rastelement 25 eingehängt, so dass sich ein Überschuss an Zugseil 9 ergibt, der an einer entsprechenden Stelle an der Kranstütze 2 aufgehängt werden kann, damit dieser Überschuss nicht behindert.For attaching the rope end of the traction cable 9 in the suspension element 19 is attached to the traction rope holding or locking element 25 which is not visible in the suspended state, but by a in the course of the traction cable 9 shown locking element 25, which then comes into play a shortening of the crane jib 2 is made. Then that is the pull rope 9 on the described Pulling deflector pulled while the catch element 25 mounted, so that there is an excess of traction cable 9, which can be suspended at a corresponding point on the crane support 2, so that this excess does not hinder.

Die Seilscheibe 8 ist mit einem Zeiger 26 und das Einhängelement 19 mit einem Zeiger 27 versehen. Diese Zeiger 26, 27 wirken mit einer Skala 28 beziehungsweise 29 zusammen, so dass eine entsprechende sichtbare Verstellung leicht möglich ist.The pulley 8 is provided with a pointer 26 and the suspension member 19 with a pointer 27. These pointers 26, 27 cooperate with a scale 28 or 29, so that a corresponding visual adjustment is easily possible.

Durch die Entkoppelung der Verstellung auf zwei Seiten ist eine größere Übersichtlichkeit und eine wirksamere Einstellung möglich.By decoupling the adjustment on two sides, a greater clarity and a more effective setting is possible.
