Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Handhabung von Lasten, insbesondere solchen Lasten, die auf einer Welle gelagert werden, wie zum Beispiel Kabeltrommeln. Die Erfindung betrifft insbesondere eine Vorrichtung zum Transport, oder zum Abwickeln solcher auf einer Welle gelagerter Lasten, insbesondere von Kabeltrommeln. Solche Vorrichtungen sind z.B. aus CN202358883U und WO2010/125051 A1 bekannt.The present invention relates to a device for handling loads, in particular those loads which are mounted on a shaft, such as cable drums. The invention relates in particular to a device for transporting or unwinding such loads mounted on a shaft, in particular cable drums. Such devices are, for example CN202358883U and WO2010 / 125051 A1 known.

Die Einlagerung von bestimmten Lasten, wie beispielsweise Kabeltrommeln, ist aufgrund der Form und der Abmessungen dieser Lasten häufig kompliziert. Im Falle von Kabeltrommeln werden diese üblicherweise in sogenannten Kabeltrommelregalen eingelagert. Hierbei wird durch den Kern der Kabeltrommel eine Welle geführt und die Kabeltrommel über diese Welle in dem Kabeltrommelregal eingehängt. Aufgrund der Dimensionen und insbesondere des Gewichts von solchen Kabeltrommeln, sind der Transport und die Einlagerung derselben üblicherweise nur mit einem Flurförderzeug möglich. Hierbei muss, um die Arbeitssicherheit zu gewährleisten, im Regelfall mit einem zweiten Arbeiter gearbeitet werden, um sicherzustellen, dass die Kabeltrommel nicht von den Staplerzinken des Flurförderzeugs verrutscht beziehungsweise abrollt. Weiterhin bestehen insbesondere dann, wenn die Kabeltrommel auf den Gabelzinken des Flurförderzeugs stehend transportiert wird, größere Risiken für die Arbeitssicherheit.The storage of certain loads, such as cable drums, is often complicated due to the shape and dimensions of these loads. In the case of cable drums, these are usually stored in so-called cable drum racks. Here, a shaft is guided through the core of the cable drum and the cable drum is suspended in the cable drum rack via this shaft. Due to the dimensions and in particular the weight of such cable drums, they can usually only be transported and stored with an industrial truck. To ensure occupational safety, a second worker must generally be used to ensure that the cable drum does not slip or roll off the truck's forks. Furthermore, there are greater risks for occupational safety, particularly if the cable drum is transported standing on the forks of the industrial truck.

Weitere Nachteile im Stand der Technik bestehen beim Abwickeln von Kabeltrommeln. Hierbei kann im Regelfall nur durch den Einsatz von Zusatzgeräten, die das Herausspringen oder Verrutschen der Kabeltrommel beim Abwickelvorgang verhindern, die Arbeitssicherheit erhöht werden.Further disadvantages in the prior art exist when unwinding cable drums. As a rule, occupational safety can only be increased by using additional devices that prevent the cable drum from jumping out or slipping during the unwinding process.

US2004/0208736A1 offenbart eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1, bei der die Gabelblätter drehbar mit dem jeweiligen Gabelrücken verbunden sind.

Hierbei weisen die Gabelzinken jeweils einen Gabelrücken, ein Gabelblatt und eine Dreheinrichtung auf. Der Gabelrücken weist eine erste Längsachse und das Gabelblatt eine zweite Längsachse auf, wobei die erste Längsachse im Wesentlichen orthogonal zu der zweiten Längsachse angeordnet ist. Weiterhin ist jedes Gabelblatt über die Dreheinrichtung um eine Drehachse, die parallel zu der Längsachse des Gabelblatts angeordnet ist, drehbar mit dem jeweiligen Gabelrücken verbunden. Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, dass das Gabelblatt zumindest eine erste Seite mit zumindest einer Aussparung zur Aufnahme einer Welle aufweist.In more detail, the device according to the invention for handling loads has a carriage and at least two fork tines arranged on this carriage.

Ein solcher Aufbau von Schlitten und daran angeordneten Gabelzinken ist dem Fachmann beispielsweise von anderen Fahrzeugen, wie beispielsweise Flurförderzeugen und z.B. Gabelstaplern bekannt. Hierbei sind die Gabelzinken über den Schlitten, der üblicherweise mittels einer Hydraulik vertikal bewegbar ist, anhebbar und absenkbar. Vorzugsweise sind die Gabelzinken verschiebbar an dem Schlitten angeordnet, sodass der Abstand zwischen den Gabelzinken zueinander vergrößert oder verkleinert werden kann. Weiter vorzugsweise sind die Gabelzinken aus einem Metall, bevorzugt aus Stahl, gefertigt.The device of the present invention has at least two fork tines which are arranged on a carriage. Such a construction of sledges and fork tines arranged thereon is known to the person skilled in the art, for example, from other vehicles, such as industrial trucks and e.g. Forklifts known. In this case, the fork tines can be raised and lowered via the slide, which can usually be moved vertically by means of a hydraulic system. The fork tines are preferably arranged displaceably on the slide, so that the distance between the fork tines can be increased or decreased with respect to one another. More preferably, the fork tines are made of a metal, preferably steel.

Jeder der Gabelzinken weist jeweils einen Gabelrücken, ein Gabelblatt, sowie eine Dreheinrichtung auf, über welche Gabelrücken und Gabelblatt miteinander verbunden sind. Vorzugsweise sind die Gabelzinken über den Gabelrücken mit dem Schlitten verbunden. Die Gabelblätter weisen in der Regel eine im Wesentlichen rechteckförmige Gestalt auf, wobei sie in ihrem letzten Abschnitt der Längserstreckung, der dem Gabelrücken entgegengesetzt angeordnet ist, bevorzugt eine verringerte Dicke aufweisen. Dies ermöglicht vorteilhafterweise die vereinfachte Aufnahme von Lasten.Each of the fork tines each has a fork back, a fork blade and a rotating device, via which the fork back and fork blade are connected to one another. The fork tines are preferably connected to the carriage via the fork back. The fork blades generally have a substantially rectangular shape, and preferably have a reduced thickness in their last section of the longitudinal extension, which is arranged opposite the back of the fork. This advantageously enables the simplified absorption of loads.

Der Gabelrücken weist eine erste Längsachse auf, die sich entlang der Längserstreckung des Gabelrückens und bevorzugt durch dessen Zentrum erstreckt. Das Gabelblatt weist ebenfalls eine (zweite) Längsachse auf, die sich entlang dessen Längserstreckung und bevorzugt durch dessen Zentrum erstreckt.The fork back has a first longitudinal axis that extends along the longitudinal extent of the fork back and preferably through the center thereof. The fork blade also has a (second) longitudinal axis, which extends along its longitudinal extent and preferably through its center.

Gabelrücken und Gabelblatt eines Gabelzinkens sind so miteinander über die Dreheinrichtung verbunden, dass die Längsachse des Gabelrückens im Wesentlichen orthogonal zu der Längsachse des Gabelblatts angeordnet ist.The fork back and fork blade of a fork tine are connected to one another via the rotating device in such a way that the longitudinal axis of the fork back is arranged essentially orthogonally to the longitudinal axis of the fork blade.

Die Dreheinrichtung ist weiterhin bezüglich des Gabelrückens sowie des Gabelblatts jeweils an einem der Enden in Längserstreckung angeordnet. Somit ergibt sich für einen Gabelzinken im Wesentlichen eine L-Form. Weiterhin weist das Gabelblatt im Regelfall eine größere Länge auf, als der Gabelrücken.The rotating device is further arranged with respect to the fork back and the fork blade at one of the ends in the longitudinal direction. This essentially results in an L-shape for a fork tine. Furthermore, the fork blade generally has a greater length than the fork back.

Das Gabelblatt ist weiterhin über die Dreheinrichtung drehbar mit dem Gabelrücken verbunden. Hierbei ist das Gabelblatt über eine Drehachse drehbar, die parallel zur Längsachse des Gabelblatts angeordnet ist. Vorzugsweise ist das Gabelblatt über die Dreheinrichtung zumindest in zwei, noch bevorzugter in drei definierte Positionen drehbar. Weiter vorzugsweise werden bei einer Vorrichtung mit zwei Gabelzinken, die Gabelblätter der Gabelzinken über die Dreheinrichtung in entgegengesetzter Richtung gedreht. Beispielsweise wird hierbei das eine Gabelblatt im Uhrzeigersinn und das andere Gabelblatt entgegen des Uhrzeigersinns gedreht.The fork blade is also rotatably connected to the back of the fork via the rotating device. Here, the fork blade is rotatable about an axis of rotation which is arranged parallel to the longitudinal axis of the fork blade. The fork blade can preferably be rotated via the rotating device in at least two, more preferably in three defined positions. More preferably, in a device with two fork tines, the fork blades of the fork tines are rotated in the opposite direction via the rotating device. For example, one fork blade is rotated clockwise and the other fork blade counterclockwise.

Jedes der beiden Gabelblätter weist weiterhin zumindest eine erste Seite auf, welche zumindest eine Aussparung zur Aufnahme einer Welle aufweist. Bevorzugt ist diese Aufnahme zur Aufnahme der Welle einer auf dieser Welle gelagerten Last geeignet. Weiterhin ist zumindest eine Aussparung des ersten Gabelzinkens so zu zumindest einer ersten Aussparung des zweiten Gabelzinkens angeordnet, dass dieselbe Welle in beiden Aussparungen aufgenommen werden kann. In anderen Worten sind zumindest zwei Aussparungen (jeweils eine davon pro Gabelblatt) paarig zueinander angeordnet. In anderen Worten sind diese zwei Aussparungen der beiden Gabelblätter einander gegenüberliegend angeordnet. Dies bedeutet weiterhin, dass die Aussparungen bei paralleler Ausrichtung der Gabelzinken zueinander im Wesentlichen in der gleichen Entfernung zum jeweiligen Gabelrücken eines Gabelzinkens angeordnet sind. Weiter bevorzugt ist bei Aufnahme einer Welle in diesen beiden Aussparungen die Längsachse der Welle, die entlang der Längserstreckung der Welle verläuft, im Wesentlichen orthogonal zu den Längsachsen der Gabelblätter angeordnet. Eine auf einer Welle gelagerte Last, wie beispielsweise eine Kabeltrommel, durch deren Kern die Welle geführt wurde, wird dann vorzugsweise zwischen den beiden Gabelzinken transportiert.Each of the two fork blades also has at least one first side, which has at least one recess for receiving a shaft. This receptacle is preferably suitable for receiving the shaft of a load mounted on this shaft. Furthermore, at least one recess of the first fork tine is arranged in relation to at least one first recess of the second fork tine in such a way that the same shaft can be received in both recesses. In other words, at least two recesses (one each per fork blade) are arranged in pairs with one another. In other words, these two recesses of the two fork blades are arranged opposite one another. This also means that the recesses are arranged at substantially the same distance from the respective fork back of a fork tine when the fork tines are aligned parallel to one another. Furthermore, when a shaft is received in these two cutouts, the longitudinal axis of the shaft, which runs along the longitudinal extent of the shaft, is arranged essentially orthogonally to the longitudinal axes of the fork blades. A load mounted on a shaft, such as a cable drum, through the core of which the shaft was guided, is then preferably transported between the two fork tines.

Vorteilhafterweise führen die Aussparungen in den Gabelblättern der Gabelzinken zu einer deutlich erhöhten Arbeitssicherheit, da die auf der Welle gelagerte Last nach Aufnahme der Welle in den Aussparungen automatisch gegen ein Wegrollen beziehungsweise ein Verrutschen während der Handhabung gesichert ist. Hierdurch wird weiterhin insbesondere der Einsatz einer zweiten Arbeitskraft überflüssig, die ohne das Vorhandensein der erfindungsgemäßen Aussparungen zur Sicherung der gehandhabten Last eingesetzt werden müsste.Advantageously, the cutouts in the fork blades of the fork tines lead to significantly increased work safety, since the load mounted on the shaft is automatically secured in the cutouts against rolling away or slipping during handling. As a result, in particular the use of a second worker, who would have to be employed to secure the handled load without the cutouts according to the invention being present, becomes superfluous.

Ein weiterer erfindungsgemäßer Vorteil besteht darin, dass eine mit der Vorrichtung der vorliegenden Erfindung gehandhabte Last direkt in ein Regal, vorzugsweise ein Hochregal, eingelagert werden kann, welches Vorrichtungen zur Aufnahme der Welle aufweist.Another advantage according to the invention is that a load handled with the device of the present invention can be stored directly in a rack, preferably a high rack, which has devices for receiving the shaft.

Bevorzugt ist die Dreheinrichtung eingerichtet, die Gabelblätter zumindest von einer ersten in eine zweite Position zu drehen, wobei in der ersten Position die Normalenrichtung der ersten Seite des Gabelblatts im Wesentlichen parallel zu der Längsachse des Gabelrückens des Gabelzinkens angeordnet ist und in der zweiten Position die Normalenrichtung der ersten Seite des Gabelblatts im Wesentlichen orthogonal zu der Längsachse des Gabelrückens des Gabelzinkens angeordnet ist.The rotating device is preferably set up to rotate the fork blades at least from a first to a second position, the normal direction of the first side of the fork blade being arranged substantially parallel to the longitudinal axis of the fork back of the fork prong in the first position and the normal direction in the second position the first side of the fork blade is arranged substantially orthogonally to the longitudinal axis of the fork back of the fork prong.

In anderen Worten ist damit die zumindest eine Aussparung der ersten Seite des Gabelblatts entgegen der Schwerkraftsrichtung ausgerichtet, wenn sich die erfindungsgemäße Vorrichtung in einem betriebsbereiten Zustand befindet. Dabei ist sie zum Beispiel bestimmungsgemäß an einem Fahrzeug, wie beispielsweise einem Flurförderzeug, bevorzugt einem Gabelstapler, angeordnet und die zumindest eine Aussparung pro Gabelzinken weist nach oben. In der zweiten Position, in der die Gabelblätter mittels der Dreheinrichtung gedreht wurden, sind die Aussparungen der beiden Gabelblätter einander zu- oder abgewandt. Im letzteren und bevorzugten Fall weisen die Aussparungen der beiden Gabelblätter nach außen.In other words, the at least one cutout on the first side of the fork blade is thus oriented counter to the direction of gravity when the device according to the invention is in an operational state. For example, it is arranged as intended on a vehicle, such as an industrial truck, preferably a forklift, and the at least one recess per fork tines points upward. In the second position, in which the fork blades have been rotated by means of the rotating device, the cutouts of the two fork blades face or face away from each other. In the latter and preferred case, the cutouts of the two fork blades face outwards.

Vorteilhafterweise wird durch die zumindest zwei Positionen, die die Gabelblätter mittels der Dreheinrichtung einnehmen können, erreicht, dass die erfindungsgemäße Vorrichtung sowohl wegen der Aussparungen zur Handhabung von Lasten geeignet ist, die auf einer Welle gelagert werden, als auch zur Handhabung von Lasten geeignet ist, die nicht auf einer Welle gelagert werden. Ein bevorzugtes Beispiel für letztere Lasten sind auf Paletten gelagerte Lasten. Die Vorrichtung gemäß der vorliegenden Erfindung stellt damit eine Möglichkeit zur sicheren und effektiven Handhabung von Lasten verschiedener Art bereit. Somit kann beispielsweise auf die Anschaffung von verschiedenen Flurförderzeugen oder zusätzlichen Anbauten für ein bestimmtes Flurförderzeug verzichtet werden, welche zeitaufwändig montiert und demontiert werden müssten.Advantageously, the at least two positions that the fork blades can assume by means of the rotating device ensure that the device according to the invention is suitable both for handling loads which are mounted on a shaft and for handling loads because of the cutouts. that are not stored on a shaft. A preferred example of the latter loads are loads stored on pallets. The device according to the present invention thus provides a possibility for the safe and effective handling of loads of various types. Thus, for example, there is no need to purchase various industrial trucks or additional attachments for a specific industrial truck, which would have to be assembled and disassembled in a time-consuming manner.

Weiter vorzugsweise sind die Gabelblätter der Gabelzinken über die Dreheinrichtung synchron zueinander drehbar. Hierunter ist zu verstehen, dass diese um den gleichen, jedoch vom Vorzeichen entgegengesetzten Drehwinkel um die Drehachse des Gabelblatts gedreht werden. Weiter vorzugsweise sind die Gabelblätter der Gabelzinken über die Dreheinrichtung in entgegengesetzter Drehrichtung zueinander drehbar.Further preferably, the fork blades of the fork tines can be rotated synchronously with one another via the rotating device. This is to be understood to mean that they are rotated around the axis of rotation of the fork blade by the same angle of rotation, but opposite the sign. More preferably, the fork blades of the fork tines can be rotated in the opposite direction to one another via the rotating device.

Weiter bevorzugt ist die Dreheinrichtung eingerichtet, die Gabelblätter in eine dritte Position zu drehen, die zwischen der ersten und der zweiten Position liegt. Wird die zweite Position des ersten und zweiten Gabelblattes mit einem Drehwinkel von 0° bezeichnet und weiterhin die erste Position des ersten Gabelblatts mit einem Drehwinkel von -90° und die erste Position des zweiten Gabelblatts mit einem Drehwinkel von +90°, so liegt die dritte Position des ersten Gabelblatts bei einem Drehwinkel zwischen 0 und -90°, bevorzugt bei - 45° und die dritte Position des zweiten Gabelblatts bei einem Drehwinkel zwischen 0° und +90°, bevorzugt bei +45°.More preferably, the rotating device is set up to turn the fork blades into a third position, which lies between the first and the second position. If the second position of the first and second fork blades is designated with a rotation angle of 0 ° and the first position of the first fork blade with a rotation angle of -90 ° and the first position of the second fork blade with a rotation angle of + 90 °, the third lies Position of the first fork blade at an angle of rotation between 0 and -90 °, preferably at - 45 ° and the third position of the second fork blade at an angle of rotation between 0 ° and + 90 °, preferably at + 45 °.

Vorteilhafterweise kann bei einer Einstellung eines Drehwinkels der beiden Gabelblätter, der zwischen der ersten und der zweiten Position liegt und der bevorzugt bei einem Drehwinkel von -45° beziehungsweise +45° liegt, zusätzlich eine Last transportiert werden, die eine fassähnliche Form aufweist. Eine solche Last, wie beispielsweise ein Fass, kann dann vorteilhafterweise liegend transportiert werden. Hierbei wird insbesondere ein Wegrollen der fassförmigen/zylinderförmigen Last beim Transport derselben, insbesondere beim Beschleunigen oder Abbremsen des Flurförderzeugs vermieden, was insbesondere zu einer Erhöhung der Arbeitssicherheit beiträgt.Advantageously, when setting an angle of rotation of the two fork blades, which lies between the first and the second position, and the is preferably at an angle of rotation of -45 ° or + 45 °, additionally a load can be transported which has a barrel-like shape. Such a load, such as a barrel, can then advantageously be transported lying down. In particular, rolling away of the barrel-shaped / cylindrical load during transport thereof, in particular when accelerating or braking the industrial truck, is avoided, which in particular contributes to an increase in occupational safety.

Die Dreheinrichtung kann bevorzugt weiterhin dazu eingerichtet sein, die Gabelblätter in zumindest einer Position zu arretieren. Weiter vorzugsweise lassen sich die Gabelblätter in mehreren Positionen, insbesondere in den zumindest zwei und/oder drei zuvor beschriebenen Positionen, arretieren. Gleichbedeutend mit der Arretierung der Gabelblätter in einer bestimmten Position ist die Arretierung der Dreheinrichtung in einer bestimmten Position.The rotating device can preferably also be set up to lock the fork blades in at least one position. More preferably, the fork blades can be locked in several positions, in particular in the at least two and / or three positions described above. Synonymous with locking the fork blades in a certain position is locking the turning device in a certain position.

Die Arretierung der Dreheinrichtung beziehungsweise der Gabelblätter in einer bestimmten Position kann auf jede dem Fachmann geläufige Art und Weise erfolgen. Beispielsweise kann hierzu eine hydraulische oder elektromechanisch betätigte Dreheinrichtung vorgesehen sein. Besonders bevorzugt erfolgt die Arretierung jedoch rein mechanisch, weiter vorzugsweise mittels eines Hebels, der in einer Aussparung der Dreheinrichtung eingreift und hierüber die Drehung der Gabelblätter um deren Drehachse verhindert. Die Anzahl und Anordnung der Aussparungen der Dreheinrichtungen entspricht dabei der Anzahl und den einzustellenden Drehwinkeln der jeweiligen Positionen, die die Gabelblätter einnehmen können. Hierdurch wird ein sehr kostengünstiger und wartungsarmer Aufbau erreicht. Bevorzugt ist der Hebel innerhalb des Gabelrückens angeordnet.The rotating device or the fork blades can be locked in a certain position in any manner familiar to the person skilled in the art. For example, a hydraulic or electromechanically operated rotating device can be provided for this purpose. However, the locking is particularly preferably carried out purely mechanically, further preferably by means of a lever which engages in a recess in the rotating device and thereby prevents the fork blades from rotating about their axis of rotation. The number and arrangement of the recesses of the rotating devices corresponds to the number and the angle of rotation to be set for the respective positions that the fork blades can assume. This results in a very cost-effective and low-maintenance construction. The lever is preferably arranged within the back of the fork.

Durch die Arretierung der Dreheinrichtung beziehungsweise der Gabelblätter in bestimmten Positionen wird die sichere Einstellung der Position der Gabelblätter gewährleistet. Weiterhin wird somit gewährleistet, dass die Überführung der Gabelblätter von einer Position in eine andere Position einfach und sicher von einer einzelnen Person durchgeführt werden kann. Die Ausgestaltung der Arretierung als rein mechanische Vorrichtung weist darüber hinaus den weiteren Vorteil auf, dass teure und störungsanfällige Komponenten in der Vorrichtung vermieden werden.By locking the rotating device or the fork blades in certain positions, the safe setting of the position of the fork blades is ensured. This also ensures that the transfer of the fork blades from one position to another position can be carried out easily and safely by a single person. The Designing the lock as a purely mechanical device also has the further advantage that expensive and fault-prone components in the device are avoided.

Bevorzugt wird der Hebel so innerhalb des Gabelrückens angeordnet, dass ein Endabschnitt des Hebels aus dem Gabelrücken hervorsteht und leicht von einem Arbeiter ergriffen und betätigt werden kann. Weiter bevorzugt weist der Endabschnitt des Hebels einen Griff auf.The lever is preferably arranged within the back of the fork in such a way that an end section of the lever protrudes from the back of the fork and can be easily gripped and actuated by a worker. More preferably, the end portion of the lever has a handle.

In einer weiteren bevorzugten Ausführungsform ist der Hebel zur Arretierung der Dreheinrichtung beziehungsweise des Gabelblatts federvorbelastet ausgeführt. Hierbei muss der Hebel, um die Arretierung zu lösen, entgegen einer Federkraft bewegt werden. Dies hat eine noch sicherere Handhabung des Hebels, insbesondere durch einen einzelnen Arbeiter, zur Folge. Weiterhin wird die Arretierungsposition des Hebels gesichert.In a further preferred embodiment, the lever for locking the rotating device or the fork blade is designed to be spring-loaded. The lever must be moved against a spring force in order to release the lock. This results in an even safer handling of the lever, especially by a single worker. Furthermore, the locking position of the lever is secured.

Weiterbevorzugt weist jedes Gabelblatt zumindest zwei Aussparungen zur Aufnahme der Welle auf. Hierbei sind diese Aussparungen in unterschiedlichem Abstand zum Gabelrücken entlang des Gabelblatts angeordnet.Furthermore, each fork blade has at least two cutouts for receiving the shaft. Here, these recesses are arranged at different distances from the back of the fork along the fork blade.

Dies hat vorteilhafterweise zur Folge, dass die Welle und damit die mittels der Welle gelagerte Last näher an den Gabelrücken der Gabelzinken beziehungsweise weiter entfernt von den Gabelrücken der Gabelzinken gehandhabt werden können.This advantageously has the consequence that the shaft and thus the load mounted by means of the shaft can be handled closer to the fork back of the fork tines or further away from the fork back of the fork tines.

Zum einen wird hierbei durch eine Annäherung der Last an die Gabelrücken der Gabelzinken die Tragkraft der Vorrichtung beziehungsweise das maximale Aufnahmegewicht der Vorrichtung und/oder des Fahrzeugs an dem diese befestigt ist erhöht. Demgegenüber wird bei einer Platzierung in größerer Entfernung von den Gabelrücken der Gabelzinken zum einen die Handhabung von Lasten mit einem größeren Durchmesser ermöglicht. Zum anderen wird hierdurch auch eine verbesserte Platzierung beziehungsweise eine erhöhte Arbeitssicherheit erreicht. Beispielsweise ist dies der Fall, wenn eine Kabeltrommel mittels der Vorrichtung in die Nähe eines Grabens transportiert werden soll, in welchem das Kabel zu verlegen ist. In einem solchen Fall muss die Vorrichtung beziehungsweise das Fahrzeug, an welchem die erfindungsgemäße Vorrichtung angebracht ist, nicht so nah an die Grube heranfahren, als dies der Fall sein würde, wenn die Kabeltrommel näher an den Gabelrücken der Gabelzinken angeordnet wäre.On the one hand, the load-bearing capacity of the device or the maximum absorption weight of the device and / or the vehicle to which it is attached is increased by an approximation of the load to the fork backs of the fork tines. In contrast, when placed further away from the fork back of the fork tines, it is possible to handle loads with a larger diameter. On the other hand, this also results in improved placement and increased occupational safety. For example, this is the case when a Cable drum is to be transported by means of the device in the vicinity of a trench in which the cable is to be laid. In such a case, the device or the vehicle on which the device according to the invention is attached does not have to move as close to the pit as would be the case if the cable drum were arranged closer to the fork back of the fork tines.

Weiterhin führt das Vorhandensein von mehreren Aussparungen zu Aufnahme einer Welle, die in verschiedenen Abständen zum Gabelrücken entlang der Längserstreckung der Gabelblätter angeordnet sind, dazu, dass die transportierte Last in Kabeltrommelregale einsortiert werden kann, die verschiedene Regaltiefen aufweisen.Furthermore, the presence of several recesses for receiving a shaft, which are arranged at different distances from the fork back along the longitudinal extension of the fork blades, means that the transported load can be sorted into cable drum racks which have different rack depths.

Bevorzugt befindet sich die erste der zumindest zwei Aussparungen zur Aufnahme einer Welle im ersten Drittel der Längserstreckung des Gabelblatts, während die zweite der zumindest zwei Aussparungen im dritten Drittel des Gabelblatts angeordnet ist.The first of the at least two cutouts for receiving a shaft is preferably located in the first third of the longitudinal extent of the fork blade, while the second of the at least two cutouts is arranged in the third third of the fork blade.

Noch bevorzugter weist das Gabelblatt mehr als zwei Aussparungen zur Aufnahme einer Welle auf, weiter bevorzugt drei oder vier solcher Aussparungen. Hierbei sind diese Aussparungen bevorzugt in gleichmäßigen Abständen zueinander und entlang der Längserstreckung des Gabelblatts angeordnet.Even more preferably, the fork blade has more than two cutouts for receiving a shaft, more preferably three or four such cutouts. In this case, these cutouts are preferably arranged at uniform distances from one another and along the longitudinal extent of the fork blade.

Weiter bevorzugt umfassen die Gabelblätter der zumindest zwei Gabelzinken der erfindungsgemäßen Vorrichtung die gleiche Anzahl von Aussparungen. Noch bevorzugter sind diese Aussparung aller Gabelblätter der Vorrichtung in gleichen Abständen relativ zu den Gabelrücken des jeweiligen Gabelblatts angeordnet.More preferably, the fork blades of the at least two fork tines of the device according to the invention comprise the same number of cutouts. Even more preferably, this recess of all fork blades of the device is arranged at equal intervals relative to the fork back of the respective fork blade.

Die Aussparungen können jede geeignete Form aufweisen, die die Aufnahme einer Welle gewährleistet. Vorzugsweise sind sie jedoch keilförmig und/oder halbkreisförmig ausgeführt. Hierdurch wird eine sichere Lagerung der aufgenommenen Welle besonders gewährleistet. Weiter vorzugsweise werden die Aussparungen durch Einschweißen, Einbrennen oder Einfräsen in die Gabelblätter erzeugt. Da typische für Kabeltrommeln verwendete Wellen einen Durchmesser von ungefähr 50 mm beziehungsweise 60 mm aufweisen, sind die Aussparungen bevorzugt an diese Dimensionen angepasst, dies ist insbesondere bei den halbkreisförmig ausgestalteten Aussparungen der Fall.The recesses can have any suitable shape that ensures the reception of a shaft. However, they are preferably wedge-shaped and / or semicircular. This ensures safe storage of the recorded wave particularly guaranteed. The cutouts are further preferably produced by welding, baking or milling into the fork blades. Since typical shafts used for cable drums have a diameter of approximately 50 mm or 60 mm, the cutouts are preferably adapted to these dimensions, this is particularly the case with the semicircular cutouts.

Weiter vorzugsweise ist an dem Gabelblatt zumindest eine Sicherungseinrichtung zur Fixierung der Welle in der Aussparung angeordnet. Besonders bevorzugt weisen alle der Aussparungen eines Gabelblatts eine solche Sicherungseinrichtung auf. Für die Sicherungseinrichtung der vorliegenden Erfindung kommt jegliche Einrichtung in Frage, die das Herausspringen oder Herausrutschen einer in der Aussparung aufgenommenen Welle zusätzlich verhindert. Dies wird beispielsweise über einen in der Nähe der Aussparung angebrachten Riegel ermöglicht, der nach Aufnahme der Welle in die Aussparung über die Aussparung gedreht oder geschoben wird und somit gewährleistet, dass die Welle beziehungsweise die Last, insbesondere beim Anfahren oder Abbremsen eines mit der erfindungsgemäßen Vorrichtung ausgestatteten Flurförderzeugs sicher in der Aussparung verbleibt.Further preferably, at least one securing device for fixing the shaft in the recess is arranged on the fork blade. All of the cutouts in a fork blade particularly preferably have such a securing device. Any device that additionally prevents a shaft accommodated in the recess from jumping out or slipping out is suitable for the securing device of the present invention. This is made possible, for example, by means of a bolt attached in the vicinity of the cutout, which after the shaft has been received is rotated or pushed into the cutout via the cutout and thus ensures that the shaft or the load, in particular when starting or braking a device with the device according to the invention equipped truck remains securely in the recess.

Die vorliegende Erfindung stellt ebenfalls ein Fahrzeug bereit, welches die zuvor beschriebene Vorrichtung umfasst. Hierbei kann die Vorrichtung sämtliche zuvor beschriebenen Merkmale umfassen, die im Folgenden nicht im Einzelnen wiederholt werden sollen.The present invention also provides a vehicle comprising the device described above. Here, the device can include all of the features described above, which are not to be repeated in detail below.

Vorzugsweise weist das Fahrzeug eine Hubeinrichtung auf, die mit dem Schlitten der erfindungsgemäßen Vorrichtung verbunden ist. Hierüber kann der Schlitten und damit die daran angeordneten Gabelzinken in einer vertikalen Richtung, das heißt parallel zur Schwerkraftrichtung, bewegt werden.The vehicle preferably has a lifting device which is connected to the carriage of the device according to the invention. The slide and thus the fork tines arranged thereon can be moved in this way in a vertical direction, that is to say parallel to the direction of gravity.

Weiter vorzugsweise ist das Fahrzeug ausgewählt aus der Gruppe bestehend aus Flurförderzeug, Gabelstapler, Hubwagen und/oder Radlader.The vehicle is further preferably selected from the group consisting of industrial truck, forklift, pallet truck and / or wheel loader.

Die vorliegende Erfindung ist weiterhin ausgerichtet auf die Verwendung der zuvor beschriebenen Vorrichtung, sowie des zuvor beschriebenen Fahrzeugs zum Transport, zur Einlagerung und/oder zur Abwicklung von einer auf einer Welle gelagerten Kabeltrommel.The present invention is further directed to the use of the device described above, as well as the vehicle described above for the transport, storage and / or handling of a cable drum mounted on a shaft.

Insbesondere im Fall der Verwendung eines erfindungsgemäßen Radladers mit daran angebrachter Vorrichtung zur Abwicklung einer auf einer Welle gelagerten Kabeltrommel bringt dies den Vorteil mit sich, dass ein bisher erforderlicher, sogenannter Abtrommelwagen am Baugrund nun nicht mehr erforderlich ist. Vielmehr kann diese Aufgabe nun durch den Radlader selbst übernommen werden kann.In particular in the case of using a wheel loader according to the invention with an attached device for handling a cable drum mounted on a shaft, this has the advantage that a so-called drum reel wagon previously required on the ground is no longer required. Rather, this task can now be performed by the wheel loader itself.

Die zuvor beschriebenen einzelnen Ausführungsformen der Erfindung sind frei miteinander kombinierbar, solange nicht explizit etwas Gegenteiliges ausgeführt wurde oder ein offensichtlicher Ausschluss entgegensteht.The individual embodiments of the invention described above can be freely combined with one another, unless something to the contrary has been explicitly carried out or there is an obvious exclusion.

Weitere Vorteile, Einzelheiten und Merkmale der Erfindung ergeben sich nachfolgend aus den erläuterten Ausführungsbeispielen. Dabei zeigt

Figur 1:
Eine Ausführungsform der erfindungsgemäßen Vorrichtung mit vier Aussparungen pro Gabelblatt.
Further advantages, details and features of the invention result from the exemplary embodiments explained below. It shows
Figure 1:
An embodiment of the device according to the invention with four recesses per fork blade.

In der nun folgenden Beschreibung wird auf ein spezielles Fahrzeug (Gabelstapler) eingegangen, an welchem die erfindungsgemäße Vorrichtung angebracht ist. Dies soll jedoch keinerlei Einschränkung bedeuten.In the description that follows, a special vehicle (forklift truck) to which the device according to the invention is attached is dealt with. However, this should not mean any restriction.

Figur 1 zeigt eine Ausführungsform der Erfindung, bei der die erfindungsgemäße Vorrichtung (1) an einen Gabelstapler (nicht dargestellt) angebracht wurde. Die Anbringung erfolgte hierbei über den Schlitten (2), der mittels einer Hydraulik vertikal bewegbar ist, d. h. angehoben und abgesenkt werden kann. Figure 1 shows an embodiment of the invention, in which the device (1) according to the invention was attached to a forklift (not shown). The attachment was carried out via the carriage (2), which can be moved vertically by means of a hydraulic system, ie it can be raised and lowered.

An dem Schlitten (2) sind zwei Gabelzinken (3) angeordnet. Diese sind parallel und in gleicher Höhe relativ zueinander angeordnet. Die beiden Gabelzinken (3) sind weiterhin horizontal verschiebbar am Schlitten (2) angeordnet. Über die Verschiebbarkeit der Gabelzinken (3) an dem Schlitten (2) wird gewährleistet, dass Lasten verschiedener Dimensionen aufgenommen werden können.Two fork tines (3) are arranged on the carriage (2). These are arranged parallel and at the same height relative to each other. The two forks (3) are furthermore horizontally displaceable on the carriage (2). The displaceability of the fork tines (3) on the carriage (2) ensures that loads of different dimensions can be absorbed.

Weiterhin können die Gabelzinken (3) über den Schlitten (2) mittels der Hydraulik ebenfalls in vertikaler Richtung bewegt werden, d. h. mit oder entgegen der Schwerkraftsrichtung (S) angehoben bzw. abgesenkt werden.Furthermore, the fork tines (3) can also be moved in the vertical direction via the slide (2) by means of the hydraulics, i.e. H. be raised or lowered with or against the direction of gravity (S).

Die Gabelzinken (3) bestehen aus jeweils einem Gabelrücken (4), einem Gabelblatt (5) und einer Dreheinrichtung (6). Die Dreheinrichtung (6) bildet hierbei das Verbindungsglied zwischen Gabelrücken (4) und Gabelblatt (5) und ist hierbei jeweils an einem Ende von Gabelrücken bzw. Gabelblatt in Längserstreckung derselben angeordnet.The fork tines (3) each consist of a fork back (4), a fork blade (5) and a rotating device (6). The rotating device (6) forms the connecting link between the fork back (4) and the fork blade (5) and is arranged in each case at one end of the fork back or fork blade in the longitudinal extension thereof.

Die Gabelrücken (4) weisen eine Längsachse (R) auf, die entlang der Längserstreckung des Gabelrückens angeordnet ist und durch dessen Zentrum verläuft. Gleichsam weisen die Gabelblätter (5) ebenfalls eine Längsachse (B) auf, die entlang der Längserstreckung der Gabelblätter und ebenfalls durch deren Zentrum verläuft. Gabelrücken (4) und Gabelblatt (5) sind so über die Dreheinrichtung (6) miteinander verbunden, dass die Längsachse des Gabelrückens (R) orthogonal zu der Längsachse des Gabelblatts (B) steht. Weiterhin sind die Längsachsen der Gabelrücken (R) beider Gabelzinken (3) parallel zueinander angeordnet, sowie auch die Längsachsen der Gabelblätter (B) beider Gabelzinken (3) parallel zueinander angeordnet sind.The fork back (4) has a longitudinal axis (R) which is arranged along the longitudinal extent of the fork back and runs through the center thereof. At the same time, the fork blades (5) also have a longitudinal axis (B) which runs along the longitudinal extent of the fork blades and also through the center thereof. The fork back (4) and fork blade (5) are connected to one another via the rotating device (6) in such a way that the longitudinal axis of the fork back (R) is orthogonal to the longitudinal axis of the fork blade (B). Furthermore, the longitudinal axes of the fork back (R) of both fork tines (3) are arranged parallel to one another, and also the longitudinal axes of the fork blades (B) of both fork tines (3) are arranged parallel to one another.

Die Gabelzinken (3) weisen eine im Wesentlichen L-förmige Gestalt auf und sind mit ihren Gabelrücken (4) am Schlitten (2) angebracht.The fork tines (3) have an essentially L-shaped shape and are attached to the carriage (2) with their fork backs (4).

Die Gabelblätter (5) sind über die Dreheinrichtung (6) drehbar mit den Gabelrücken (4) verbunden. Hierbei können die Gabelblätter (4) um eine Drehachse (D) gedreht werden, die parallel zu der Längsachse des jeweiligen Gabelblatts (B) und durch das Zentrum der Dreheinrichtung (6) verläuft.The fork blades (5) are rotatably connected to the fork back (4) via the rotating device (6). Here, the fork blades (4) can be rotated about an axis of rotation (D) which runs parallel to the longitudinal axis of the respective fork blade (B) and through the center of the rotating device (6).

Die Längsachsen der Gabelrücken (R) verlaufen weiterhin im Wesentlichen parallel zur Schwerkraftsrichtung (S), während die Längsachsen der Gabelrücken (R), sowie die Drehachsen (D) orthogonal zu der Schwerkraftsrichtung (S) angeordnet sind.The longitudinal axes of the fork back (R) continue to run essentially parallel to the direction of gravity (S), while the longitudinal axes of the fork back (R) and the axes of rotation (D) are arranged orthogonally to the direction of gravity (S).

Die Gabelblätter (5) beider Gabelzinken (3) weisen jeweils vier Aussparung (8) zur Aufnahme einer Welle auf, die in gleichmäßigen Abständen zueinander entlang der Längserstreckung der Gabelblätter (5) in einer ersten Seite (7) der Gabelblätter angeordnet sind. Die Aussparung (8) weisen hierbei eine halbkreisförmige Ausgestaltung auf, welche die sichere Aufnahme einer Welle besonders begünstigt.The fork blades (5) of both fork tines (3) each have four recesses (8) for receiving a shaft, which are arranged at equal distances from one another along the longitudinal extent of the fork blades (5) in a first side (7) of the fork blades. The cutout (8) has a semicircular configuration, which particularly favors the secure reception of a shaft.

Weiterhin sind alle vier Aussparungen (8) eines Gabelzinkens (3) paarig zu den Aussparungen (8) des zweiten Gabelzinkens (3) angeordnet. Dies bedeutet, dass die einzelnen Aussparungen (8) der beiden Gabelzinken (3) in gleicher Entfernung vom Gabelrücken (4) eines Gabelzinkens (3) angeordnet sind. Hierdurch wird gewährleistet, dass eine Welle, die mittels zweier solcher paarig angeordneter Aussparungen (8) aufgenommen wurde, sicher mittels der erfindungsgemäßen Vorrichtung gehandhabt werden kann. Hierbei ist diese Welle (in der Abbildung nicht gezeigt) so angeordnet, dass ihre Längsachse, die entlang der Längserstreckung der Welle verläuft, im Wesentlichen orthogonal zu den Längsachsen der Gabelblätter (B) und orthogonal zu den Längsachsen der Gabelrücken (R) der Gabelzinken (3) angeordnet ist. In anderen Worten wird die Welle und damit die hierüber gehandhabte Last parallel zum Schlitten aufgenommen.Furthermore, all four recesses (8) of a fork prong (3) are arranged in pairs with the recesses (8) of the second fork prong (3). This means that the individual recesses (8) of the two fork tines (3) are arranged at the same distance from the fork back (4) of a fork tine (3). This ensures that a shaft which was received by means of two such recesses (8) arranged in pairs can be safely handled by means of the device according to the invention. This shaft (not shown in the figure) is arranged so that its longitudinal axis, which runs along the longitudinal extent of the shaft, is essentially orthogonal to the longitudinal axes of the fork blades (B) and orthogonal to the longitudinal axes of the fork back (R) of the fork tines ( 3) is arranged. In other words, the shaft and thus the load handled by it is taken up parallel to the slide.

Mittels der Dreheinrichtung (6) können die Gabelblätter (5) der Gabelzinken (3) in drei definierte Positionen um die Drehachse (D) gedreht werden.By means of the rotating device (6), the fork blades (5) of the fork tines (3) can be rotated about the axis of rotation (D) in three defined positions.

Bei der in der Figur 1 gezeigten zweiten Position sind die Gabelblätter um einen Drehwinkel von 0° gedreht. In dieser zweiten Position ist die normale Richtung (N) der ersten Seite des Gabelblatts (7) orthogonal zu der Längsachse des Gabelrückens (R) bzw. orthogonal zur Schwerkraftsrichtung (S) angeordnet.At the in the Figure 1 Second position shown are the fork blades rotated by an angle of 0 °. In this second position, the normal direction (N) of the first side of the fork blade (7) is arranged orthogonal to the longitudinal axis of the fork back (R) or orthogonal to the direction of gravity (S).

Wie der Figur 1 weiterhin zu entnehmen ist, weisen die Aussparungen (8) in der ersten Seite des Gabelblatts (7) nach außen, d. h. die Aussparungen (8) der beiden Gabelzinken (3) der erfindungsgemäßen Vorrichtung (1) weisen voneinander weg.Again Figure 1 can also be seen, the cutouts (8) in the first side of the fork blade (7) point outwards, ie the cutouts (8) of the two fork tines (3) of the device (1) according to the invention point away from one another.

In dieser zweiten Position kann die erfindungsgemäße Vorrichtung insbesondere zur Handhabung von Lasten verwendet werden, die auf Paletten gelagert sind. Dies wird vorteilhafterweise durch die Ausgestaltung der Gabelblätter (5) erreicht, die eine im Wesentlichen viereckige und abgeflachte Form aufweisen. Darüber hinaus weisen die Gabelblätter (5) an den der Dreheinrichtung (6) abgewandten Seite einen Bereich kontinuierlich abnehmender Dicke auf.In this second position, the device according to the invention can be used in particular for handling loads which are stored on pallets. This is advantageously achieved by the configuration of the fork blades (5), which have an essentially square and flattened shape. In addition, the fork blades (5) have a region of continuously decreasing thickness on the side facing away from the rotating device (6).

In der ersten Position, über die die Gabelblätter (5) über die Dreheinrichtung (6) gedreht werden können, ist die Normalenrichtung (N) der ersten Seite des Gabelblatts (7) im Wesentlichen parallel zu der Längsachse des Gabelrückens (R) und im Wesentlichen parallel zur Schwerkraftsrichtung (S) angeordnet. Hierbei sind die Gabelblätter um einen Betrag von ungefähr 90° gedreht, wobei die beiden Gabelblätter einen Drehwinkel mit unterschiedlichem Vorzeichen aufweisen. Bei Bezugnahme auf die Figur 1 bedeutet dies, dass das in Aufsicht linke Gabelblatt um 90° mit dem Uhrzeigersinn gedreht wurde, d.h. einen Drehwinkel von -90° aufweist und das in Aufsicht rechte Gabelblatt um 90 ° gegen den Uhrzeigersinn gedreht wurde, d.h. einen Drehwinkel von 90° aufweist.In the first position, via which the fork blades (5) can be rotated via the rotating device (6), the normal direction (N) of the first side of the fork blade (7) is essentially parallel to the longitudinal axis of the fork back (R) and essentially arranged parallel to the direction of gravity (S). Here, the fork blades are rotated by an amount of approximately 90 °, the two fork blades having an angle of rotation with a different sign. When referring to the Figure 1 this means that the top left fork blade has been rotated 90 ° clockwise, ie has a rotation angle of -90 ° and the top fork blade has been rotated 90 ° counterclockwise, ie has a rotation angle of 90 °.

In anderen Worten weisen die Aussparungen (8) in den Gabelblättern (5) in der ersten Position nach oben. In dieser ersten Position kann dann die Welle in jeweils einem von zwei paarig zueinander angeordneten Aussparungen (8) der beiden Gabelzinken (3) angeordnet werden. Dies erfolgt vorteilhafterweise dadurch, dass sich der Gabelstapler, an dem die erfindungsgemäße Vorrichtung (1) angebracht ist, der Last/Welle mit abgesenktem Schlitten (2) und damit abgesenkten Gabelzinken (3) nähert und die Gabelzinken (3) mit in die erste Position gebrachten Gabelblättern (5), d. h. mit nach oben weisenden Aussparungen (8), derart unterhalb der Welle positioniert werden, dass die Welle direkt oberhalb einem Paar der Aussparungen (8) der beiden Gabelblätter (5) angeordnet ist. Daraufhin wird der Schlitten (3) und damit die Gabelzinken (3) über die Hydraulik des Gabelstaplers angehoben, bis sich die Welle in den beiden Aussparungen (8) befindet. Wird nun die Last/Welle über die Hydraulik weiter angehoben, so erfolgt eine automatische und sichere Fixierung der Last/Welle in den Aussparungen (8) über das Eigengewicht der Last.In other words, the cutouts (8) in the fork blades (5) point upwards in the first position. In this first position, the shaft can then be arranged in one of two recesses (8) of the two fork tines (3) arranged in pairs. This advantageously takes place in that the forklift, to which the device (1) according to the invention is attached, approaches the load / shaft with the carriage (2) lowered and the fork tines (3) lowered and the fork tines (3) into the first position brought fork blades (5), ie with upward-facing recesses (8), positioned below the shaft such that the Shaft is arranged directly above a pair of the recesses (8) of the two fork blades (5). Then the carriage (3) and thus the forks (3) are lifted by the forklift hydraulics until the shaft is in the two recesses (8). If the load / shaft is raised further via the hydraulics, the load / shaft is automatically and securely fixed in the recesses (8) via the weight of the load.

Die in der Figur 1 dargestellte Vorrichtung (1) weist darüber hinaus noch eine dritte Position auf, in die die Gabelblätter (5) über die Dreheinrichtung (6) gebracht werden können. Diese dritte Position liegt jeweils zwischen der ersten und der zweiten Position und weist einen Drehwinkel von etwa -45° bzw. etwa +45° der beiden Gabelblätter auf. Bezogen auf die Figur 1 bedeutet dies, dass die ersten Seiten der Gabelblätter (7) entgegen der Schwerkraftsrichtung (S) gedreht wurden, bzw. dass das in Aufsicht linke Gabelblatt um etwa 45° mit dem Uhrzeigersinn gedreht wurde, d.h. einen Drehwinkel von etwa -45° aufweist und das in Aufsicht rechte Gabelblatt um etwa 45° gegen den Uhrzeigersinn gedreht wurde, d.h. einen Drehwinkel von etwa 45° aufweist.The in the Figure 1 The device (1) shown also has a third position into which the fork blades (5) can be brought via the rotating device (6). This third position lies between the first and the second position and has an angle of rotation of approximately -45 ° or approximately + 45 ° of the two fork blades. Related to the Figure 1 this means that the first sides of the fork blades (7) were rotated against the direction of gravity (S), or that the fork blade on the left, viewed from above, was rotated clockwise by approximately 45 °, ie has an angle of rotation of approximately -45 ° and that when viewed from above, the right fork blade was rotated counterclockwise by approximately 45 °, ie has an angle of rotation of approximately 45 °.

In dieser dritten Position, bei denen die beiden Gabelposition (5) der Gabelzinken (3) in etwa V-förmig angeordnet sind, lassen sich insbesondere Fässer sehr sicher transportierten. Hierbei werden diese Fässer so auf der erfindungsgemäßen Vorrichtung (1) angeordnet, dass ihre gewölbte Oberfläche mit den in die dritte Position verbrachten Gabelblättern (5) in Kontakt steht.In this third position, in which the two fork positions (5) of the fork tines (3) are arranged approximately in a V-shape, barrels in particular can be transported very safely. These barrels are arranged on the device (1) according to the invention in such a way that their curved surface is in contact with the fork blades (5) brought into the third position.

Die Dreheinrichtung (6) ist weiterhin dazu ausgelegt, die Gabelblätter in den drei genannten Positionen zu arretieren. Die Arretierung erfolgt hierbei rein mechanisch und mittels eines federvorbelasteten Hebels (9) der innerhalb der Gabelrücken (4) der Gabelzinken (3) angeordnet ist. Der Hebel (9) greift hierbei zur Arretierung in Aussparungen der Dreheinrichtung (6) ein und verhindert hierüber deren Drehung um die Drehachse (D). Der Hebel (9) weist weiterhin einen Endabschnitt auf, der als ein Griff ausgebildet ist. Weiterhin ist der Hebel (9) so innerhalb des Gabelrückens (4) angeordnet, dass sein Endabschnitt bzw. der Griff aus dem Gabelrücken hervorsteht und somit leicht von einem Arbeiter ergriffen und betätigt werden kann.The rotating device (6) is also designed to lock the fork blades in the three positions mentioned. The locking is done purely mechanically and by means of a spring-loaded lever (9) which is arranged within the fork back (4) of the fork tines (3). The lever (9) engages in the recesses of the rotating device (6) and thereby prevents their rotation about the axis of rotation (D). The lever (9) also has an end section which is designed as a handle. Furthermore, the lever (9) is arranged inside the fork back (4) in such a way that its end section or the handle protrudes from the back of the fork and can therefore be easily gripped and operated by a worker.

Die in Figur 1 gezeigte Vorrichtung (1) der Erfindung kann weiterhin insbesondere zum Abwickeln einer Kabeltrommel Verwendung finden, die auf einer Welle gelagert wurde. Hierbei kommt vorteilhafterweise die halbkreisförmige Ausgestaltung der Aussparungen (8) zur Aufnahme der Welle zum Tragen, da die von der Vorrichtung (1) gehandhabte Kabeltrommel hierdurch leicht rotiert werden kann.In the Figure 1 The device (1) of the invention shown can furthermore be used in particular for unwinding a cable drum which has been mounted on a shaft. The semicircular configuration of the cutouts (8) for receiving the shaft is advantageous here, since the cable drum handled by the device (1) can thereby be easily rotated.
