Definitions
- the invention relates to a transport device comprising a transport vehicle with a drive and a rope mounted at at least two points, wherein the transport vehicle is movable by means of the drive along the rope.
- the invention relates to a method for moving a transport vehicle along a rope mounted between two points, in particular with a transport device of the type mentioned.
- the invention relates to a use of such a device.

Since steel cables with a high rigidity are usually used, slight changes in the deflection lead to large changes in the cable tension. This can affect a life of the rope and in extreme cases lead to a rupture of the rope. In addition, a continuous movement of the transport vehicle is hampered because of the discontinuous rope tension.

- a cable force in a cable deflection constant-holding element is possible, such as a pure weight load of the rope, especially at one end.
- the integration of a damper element, the a cable force depending on a speed of the deflection applies is another possibility.
- elements described above can be combined with one another in order to realize a storage location optimally adapted to the respective conditions.
- the control mechanism which automatically corrects a deflection of the rope, a rope tension can be automatically reduced due to incorrect alignment of the transport vehicle. Since the orientation of the transport vehicle in the uneven, especially in steep, terrain during a motion due to gravity constant changes, a constant corrective intervention is required to keep the transport vehicle along the defined by the stretched rope route. Only by the automatic control mechanism, for example, a driverless operation can be enabled.
- the control mechanism may include a steering sensor, a control unit and a steering, in particular a kink or Schemellenkung, wherein the steering sensor measures the orientation of the transport vehicle relative to the rope constantly and controls in a different orientation of transport vehicle and rope on the steering regulatory, until the transport vehicle is again aligned in the direction of the rope.
- control mechanism may also include GPS sensors, wherein the control unit uses the data of the GPS sensors as a basis for corrective measures.

- the cable is attached at a first end to a fixing anchor and at a second end to the movable bearing.
- a movable bearing is required to achieve the desired effect of deflectability of the rope.
- the transport device used in steep terrain to transport material over a height difference so has a training of a lower bearing point as a movable bearing found to be useful because of this weight load, which brings the transport vehicle in the rope, does not occur and thus the Bearing point can be constructively simpler.
- the cable is preferably fastened to a fixed point serving as a fix anchor, for example a support anchored in the terrain, concrete base or a stable tree.
- the rope can also be moved, in particular deflected, mounted at the upper bearing point.
- the transport vehicle has an articulated steering.
- Such steering has proved to be particularly advantageous in vehicles for rough terrain and high forces.
- the drive comprises two pulleys.
- the transport vehicle can move stable well guided along the rope, the drive is also structurally simple. Also, a particularly good power transmission is possible over a large wrap angle.
- a cable tension by means of the movable bearing point during the movement of the transport vehicle along the rope is approximately constant preserved.
- Devices in which a force can be kept constant via a deflection, are known from the prior art, for example for hanging pipes.
- the integration of such a device as a movable bearing has the particular advantage that a cable force is no longer subject to fluctuations and thus the life of the rope is increased.
- the second object is achieved in that in a method of the type mentioned, the rope is flexibly clamped at one point by means of a movable bearing and / or a deflection of the transport vehicle is automatically corrected by the rope.
- a force in the rope is kept approximately constant during a movement of the transport vehicle. As a result, the life of the rope is significantly increased.

In order to load the transport vehicle 1, additionally connected to the transport vehicle 1 crane or a Be provided gripping arm, as is known for example in agricultural and forestry machinery.
- Fig. 2 shows the transport vehicle 1 with the rope 5 in side view, wherein in addition to the transport basket 10 and the frame 2, a drive 3 is shown with two pulleys.
- a steerable axle 7 and a steering cylinder 9 for actuating a not shown articulated steering can be seen.
- Schematically illustrated is a motor 8, with which the sheaves of the drive 3 are driven.
- the function of the transport vehicle 1 is such that a weight of a load, such as wood, via the transport basket 10 and the frame 2 is derived on the eight wheels, so that an approximately uniform distribution of the force can be achieved.
- the sheaves are driven by the motor 8, wherein combustion, electric or hydraulic motors are used.
- a position determination of the transport vehicle 1 and thus a measurement of the deflection by means of GPS data is possible, which can then be used to control and / or control the movement.
- This controlled, in particular remote-controlled, and / or regulated partially or fully automatic operation makes it possible that the transport vehicle 1 can be operated without a driver.

- the cable 5 is mounted on a rigidly connected to a base fixing anchor 6 and a movable bearing 11. It can be seen that the transport vehicle 1 is located in the representation executed by solid lines on a direct connection between the fixing armature 6 and the movable bearing 11 and thus a deflection of the cable 5 from a direct connection of these two points is negligibly small.
- the movable bearing 11 can be realized via springs, dampers or elements that hold constant a force independent of a deflection.
- a combination of the individual elements is possible. This makes it possible to deflect the cable 5 on the movable bearing 11 in the direction of the fixed anchor 6, without resulting in an additional force in the cable 5. This can ensure that the cable 5 is stretched along a connecting line between the fixing anchor 6 and movable bearing 11 and a movement of the transport vehicle 1 along this rope 5 is possible, with the tracking along an uneven track transport vehicle 1 not to an unacceptably high rope tension in the rope 5 leads. As a result, the movement of the transport vehicle 1 can also be more uniform.
- the rope 5 is defined only in the direction defined by the two points Fixanker 6 and movable bearing 11 flexibly clamped and rigidly mounted in all other directions. This allows a particularly good guidance of the transport vehicle 1.
- the movable bearing 11 is preferably carried out at the lower end of the rope 5, since this then only has to absorb forces for tensioning the rope 5.
- a device for transporting wood in uneven and steep terrain used.
- the rope 5 is fixed on the fix anchor 6 and clamped flexibly to the movable bearing 11 and the transport vehicle 1 is connected to the sheaves with the cable 5.
- a force in the rope 5 during the movement of the transport vehicle 1 is kept approximately constant.

Description
Die Erfindung betrifft eine Transportvorrichtung, umfassend ein Transportfahrzeug mit einem Antrieb und ein an mindestens zwei Punkten gelagertes Seil, wobei das Transportfahrzeug mittels des Antriebes entlang des Seiles bewegbar ist.The invention relates to a transport device comprising a transport vehicle with a drive and a rope mounted at at least two points, wherein the transport vehicle is movable by means of the drive along the rope.
Weiter betrifft die Erfindung ein Verfahren zum Bewegen eines Transportfahrzeuges entlang eines zwischen zwei Punkten gelagerten Seiles, insbesondere mit einer Transportvorrichtung der eingangs genannten Art.Furthermore, the invention relates to a method for moving a transport vehicle along a rope mounted between two points, in particular with a transport device of the type mentioned.
Darüber hinaus betrifft die Erfindung eine Verwendung einer derartigen Vorrichtung.Moreover, the invention relates to a use of such a device.
Gemäß dem Stand der Technik sind verschiedene Transportvorrichtungen bekannt geworden. Aus der
Aufgabe der Erfindung ist es, eine Transportvorrichtung anzugeben, welche die Nachteile des Standes der Technik behebt oder zumindest reduziert. Insbesondere soll dabei eine Seilkraft bzw. Seilspannung auch im unebenen Gelände nicht unzulässig hoch werden. Weiter soll die Transportvorrichtung konstruktiv einfach ausgestaltet sein.The object of the invention is to provide a transport device which overcomes or at least reduces the disadvantages of the prior art. In particular, a cable force or rope tension should not be unacceptably high, even in uneven terrain. Next, the transport device should be designed structurally simple.
Darüber hinaus soll ein Verfahren der eingangs genannten Art angegeben werden, mit dem ein Transportfahrzeug auch im unebenen Gelände bewegbar ist.In addition, a method of the aforementioned type is to be specified, with which a transport vehicle is movable even on uneven terrain.
Des Weiteren soll eine Verwendung einer entsprechenden Transportvorrichtung angegeben werden.Furthermore, a use of a corresponding transport device should be specified.
Die erste Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einer Vorrichtung der eingangs genannten Art das Seil an einem Punkt mittels einer bewegbaren Lagerstelle flexibel eingespannt ist und/oder ein Regelmechanismus vorgesehen ist, der eine Ablenkung vom Seil automatisch korrigiert.The first object is achieved in that in a device of the type mentioned the rope is flexibly clamped at one point by means of a movable bearing and / or a control mechanism is provided which automatically corrects a deflection of the rope.
Mittels der bewegbaren Lagerstelle, die einerseits starr mit einem Untergrund und andererseits starr mit dem Seil verbunden ist und mittels einer Flexibilität eine Bewegung zwischen dem Seil und dem Untergrund in mindestens einer Richtung ermöglicht, wird eine Seilauslenkung ermöglicht, die nicht gleichzeitig zu einem starken Ansteigen der Seilspannung führt. Dadurch ist es möglich, das Transportfahrzeug auch im unebenen Gelände mit etwa gleichmäßiger Geschwindigkeit am Seil geführt zu bewegen und die Lebensdauer des Seiles zu erhöhen. Dabei ist die Lagerstelle bevorzugt in Richtung des gespannten Seiles flexibel bewegbar und in allen anderen Richtungen im Wesentlichen steif ausgebildet, um eine Transportrichtung des Transportfahrzeuges auch bei unebenem Gelände konstant zu halten. Die bewegbare Lagerstelle kann dabei als Feder, insbesondere umfassend einen gas- oder flüssigkeitsgefüllten Kolben oder ein Gummielement, ausgebildet sein, bei der eine Seilkraft mit der Auslenkung steigt. Alternativ ist auch eine Ausbildung als ein die Seilkraft bei einer Seilauslenkung konstanthaltendes Element möglich, wie beispielsweise eine reine Gewichtsbelastung des Seiles, insbesondere an einem Ende. Auch die Integration eines Dämpferelementes, das eine Seilkraft abhängig von einer Geschwindigkeit der Auslenkung aufbringt, ist eine weitere Möglichkeit. Darüber hinaus können oben beschriebene Elemente miteinander kombiniert sein, um eine den jeweiligen Bedingungen optimal angepasste Lagerstelle zu realisieren.By means of the movable bearing, on the one hand rigidly connected to a substrate and on the other hand rigidly connected to the rope and by means of a flexibility movement between the rope and the ground in at least one direction, a cable deflection is possible, which does not simultaneously increase the Rope tension leads. This makes it possible to move the transport vehicle even in rough terrain with approximately uniform speed on the rope and to increase the life of the rope. In this case, the bearing point is preferably flexibly movable in the direction of the tensioned cable and substantially rigid in all other directions in order to keep a transport direction of the transport vehicle constant even on uneven terrain. The movable bearing point can be designed as a spring, in particular comprising a gas- or liquid-filled piston or a rubber element, in which a cable force increases with the deflection. Alternatively, training as a cable force in a cable deflection constant-holding element is possible, such as a pure weight load of the rope, especially at one end. Also, the integration of a damper element, the a cable force depending on a speed of the deflection applies is another possibility. In addition, elements described above can be combined with one another in order to realize a storage location optimally adapted to the respective conditions.
Mit dem Regelmechanismus, der eine Ablenkung vom Seil automatisch korrigiert, kann eine Seilspannung aufgrund fehlerhafter Ausrichtung des Transportfahrzeuges automatisch reduziert werden. Da die Ausrichtung des Transportfahrzeuges im unebenen, insbesondere im steilen, Gelände während einer Bewegung schwerkraftbedingt ständigen Änderungen unterliegt, ist ein ständiges korrigierendes Eingreifen erforderlich, um das Transportfahrzeug entlang der durch das gespannte Seil definierten Strecke zu halten. Nur durch den automatischen Regelmechanismus kann beispielsweise ein fahrerloser Betrieb ermöglicht werden. Der Regelmechanismus kann einen Lenksensor, eine Regeleinheit und eine Lenkung, insbesondere eine Knick- oder Schemellenkung, umfassen, wobei der Lenksensor die Ausrichtung des Transportfahrzeuges relativ zum Seil ständig misst und bei abweichender Ausrichtung von Transportfahrzeug und Seil über die Lenkung regelnd eingreift, bis das Transportfahrzeug wieder in Richtung des Seiles ausgerichtet ist. Alternativ kann der Regelmechanismus auch GPS-Sensoren aufweisen, wobei die Regeleinheit die Daten der GPS-Sensoren als Basis für Korrekturmaßnahmen heranzieht. So kann mittels der GPS-Sensoren auch ein programmiertes Fahrziel und eine Fahrstrecke automatisiert und kontrolliert abgefahren werden. Mit einer derartigen Ausbildung sind Fahrstrecken mit einer Länge von etwa 500 Metern und weniger als 10 Metern Breite auch im unwegsamen Gelände möglich.With the control mechanism, which automatically corrects a deflection of the rope, a rope tension can be automatically reduced due to incorrect alignment of the transport vehicle. Since the orientation of the transport vehicle in the uneven, especially in steep, terrain during a motion due to gravity constant changes, a constant corrective intervention is required to keep the transport vehicle along the defined by the stretched rope route. Only by the automatic control mechanism, for example, a driverless operation can be enabled. The control mechanism may include a steering sensor, a control unit and a steering, in particular a kink or Schemellenkung, wherein the steering sensor measures the orientation of the transport vehicle relative to the rope constantly and controls in a different orientation of transport vehicle and rope on the steering regulatory, until the transport vehicle is again aligned in the direction of the rope. Alternatively, the control mechanism may also include GPS sensors, wherein the control unit uses the data of the GPS sensors as a basis for corrective measures. Thus, by means of the GPS sensors, a programmed destination and a route can be automated and controlled. With such a training routes are possible with a length of about 500 meters and less than 10 meters wide, even in rough terrain.
Es ist von Vorteil, dass das Transportfahrzeug automatisch und/oder fahrerlos verfahrbar ist. Eine automatische Verfahrbarkeit kann dabei mittels Sensoren, insbesondere Abstands- und Geschwindigkeitssensoren, realisiert werden. Weiter ist auch eine automatische Verfahrbarkeit möglich, bei welcher eine Steuerung und Regelung über GPS-Signale erfolgt. Daneben ist eine manuelle oder automatische Fernsteuerung des Transportfahrzeuges mittels einer Funkfernsteuerung möglich. Vorteil der Ausbildung, bei der ein fahrerloser Betrieb möglich ist, ist insbesondere, dass ein Verletzungsrisiko für ein Bedienpersonal ausgeschlossen werden kann. Bei einer voll- oder teilautomatischen Ausbildung des Transportfahrzeuges können Personalkosten gespart werden.It is advantageous that the transport vehicle can be moved automatically and / or without driver. An automatic mobility can be realized by means of sensors, in particular distance and speed sensors. Furthermore, an automatic movability is possible, in which a control and regulation via GPS signals. In addition, a manual or automatic remote control of the transport vehicle by means of a radio remote control is possible. Advantage of the training, in which a driverless operation is possible, in particular, that a risk of injury to an operator can be excluded. In a fully or partially automatic training of the transport vehicle personnel costs can be saved.
Es hat sich bewährt, dass das Seil an einem ersten Ende an einem Fixanker und an einem zweiten Ende an der bewegbaren Lagerstelle befestigt ist. Damit ist lediglich eine bewegbare Lagerstelle erforderlich, um den gewünschten Effekt einer Auslenkbarkeit des Seiles zu erreichen. Wird die Transportvorrichtung im steilen Gelände eingesetzt, um Material über eine Höhendifferenz zu transportieren, so hat sich eine Ausbildung einer unteren Lagerstelle als bewegbare Lagerstelle als nützlich erwiesen, da an dieser eine Gewichtsbelastung, welche das Transportfahrzeug in das Seil einbringt, nicht auftritt und dadurch die Lagerstelle konstruktiv einfacher ausgebildet werden kann. An einer oberen Lagerstelle wird das Seil bevorzugt an einem als Fixanker dienenden ortsfesten Punkt, beispielsweise einem im Gelände verankerten Träger, Betonsockel oder einem stabilen Baum, befestigt. Alternativ kann das Seil an der oberen Lagerstelle auch bewegbar, insbesondere umgelenkt, gelagert sein.It has been proven that the cable is attached at a first end to a fixing anchor and at a second end to the movable bearing. Thus, only a movable bearing is required to achieve the desired effect of deflectability of the rope. If the transport device used in steep terrain to transport material over a height difference, so has a training of a lower bearing point as a movable bearing found to be useful because of this weight load, which brings the transport vehicle in the rope, does not occur and thus the Bearing point can be constructively simpler. At an upper bearing point, the cable is preferably fastened to a fixed point serving as a fix anchor, for example a support anchored in the terrain, concrete base or a stable tree. Alternatively, the rope can also be moved, in particular deflected, mounted at the upper bearing point.
Zweckmäßigerweise ist vorgesehen, dass das Transportfahrzeug eine Knicklenkung aufweist. Eine derartige Lenkung hat sich bei Fahrzeugen für unwegsames Gelände und bei hohen auftretenden Kräften als besonders vorteilhaft erwiesen.Appropriately, it is provided that the transport vehicle has an articulated steering. Such steering has proved to be particularly advantageous in vehicles for rough terrain and high forces.
Besonders bevorzugt ist vorgesehen, dass der Antrieb zwei Seilscheiben umfasst. Mit einem derartigen Antrieb kann sich das Transportfahrzeug stabil gut geführt entlang des Seiles bewegen, wobei der Antrieb auch konstruktiv einfach ausgebildet ist. Auch ist über einen großen Umschlingungswinkel eine besonders gute Kraftübertragung möglich.It is particularly preferred that the drive comprises two pulleys. With such a drive, the transport vehicle can move stable well guided along the rope, the drive is also structurally simple. Also, a particularly good power transmission is possible over a large wrap angle.
Es kann auch vorgesehen sein, dass eine Seilspannung mittels der bewegbaren Lagerstelle während des Bewegens des Transportfahrzeuges entlang des Seiles in etwa konstant haltbar ist. Einrichtungen bei denen eine Kraft über eine Auslenkung konstant gehalten werden kann, sind aus dem Stand der Technik bekannt, beispielsweise zum Aufhängen von Rohrleitungen. Die Integration einer derartigen Einrichtung als bewegbare Lagerstelle hat insbesondere den Vorteil, dass eine Seilkraft keinen Schwankungen mehr unterliegt und damit die Lebensdauer des Seiles erhöht wird.It can also be provided that a cable tension by means of the movable bearing point during the movement of the transport vehicle along the rope is approximately constant preserved. Devices in which a force can be kept constant via a deflection, are known from the prior art, for example for hanging pipes. The integration of such a device as a movable bearing has the particular advantage that a cable force is no longer subject to fluctuations and thus the life of the rope is increased.
Die zweite Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einem Verfahren der eingangs genannten Art das Seil an einem Punkt mittels einer bewegbaren Lagerstelle flexibel eingespannt wird und/oder eine Ablenkung des Transportfahrzeuges vom Seil automatisch korrigiert wird.The second object is achieved in that in a method of the type mentioned, the rope is flexibly clamped at one point by means of a movable bearing and / or a deflection of the transport vehicle is automatically corrected by the rope.
Dadurch kann eine Seilauslenkung, wie dies beispielsweise beim Verfahren des Transportfahrzeuges entlang eines unebenen Geländes erforderlich ist, ermöglicht werden, ohne dass es zu unzulässig hohen mechanischen Beanspruchungen des Seiles kommt.This allows a cable deflection, as required, for example, when moving the transport vehicle along an uneven terrain, are made possible, without causing unacceptably high mechanical stress on the rope.
Dadurch, dass eine Ablenkung des Transportfahrzeuges vom Seil automatisch korrigiert wird, kann die mechanische Beanspruchung des Seiles weiter reduziert werden.The fact that a deflection of the transport vehicle is automatically corrected by the rope, the mechanical stress of the rope can be further reduced.
Bevorzugt kann es auch sein, dass eine Kraft im Seil während einer Bewegung des Transportfahrzeuges etwa konstant gehalten wird. Dadurch wird die Lebensdauer des Seiles wesentlich erhöht.It may also be preferred that a force in the rope is kept approximately constant during a movement of the transport vehicle. As a result, the life of the rope is significantly increased.
Die dritte Aufgabe wird dadurch gelöst, dass eine erfindungsgemäße Transportvorrichtung zum Transportieren von Holz im unwegsamen Gelände verwendet wird.The third object is achieved in that a transport device according to the invention is used for transporting wood in rough terrain.
Dadurch kann ein Abtransport von Holz aus schwer erreichbarem Gelände, insbesondere über große Höhendifferenzen, stark vereinfacht werden.As a result, a removal of wood from hard-to-reach terrain, especially over large height differences, are greatly simplified.
