Aus dem Stand der Technik sind Baumaschinen mit einer Vielzahl von unterschiedlichen Trommelwinden bekannt. Bei Bodenbearbeitungswerkzeugen, beispielsweise einer Bohrschnecke, einer Schlitzwandfräse, einem Soil-Mixing-Gestänge oder einem Bohrgestänge, sind diese an einem Mast geführt und werden von einem Hubseil getragen. Zum Antrieb des Hubseils ist eine Winde vorgesehen.From the prior art construction machines with a variety of different drum winches are known. In tillage tools, such as a drilling auger, a trench cutter, a soil mixing linkage or a drill pipe, these are guided on a mast and are supported by a hoist rope. To drive the hoist rope a winch is provided.
Weiterhin können Winden für Förderschläuche, Hydraulikschläuche oder Elektrokabel eingesetzt werden. Insbesondere bei Förderschläuchen mit relativ großem Schlauchdurchmesser ist eine saubere Schlauchwicklung für den Verschleiß maßgeblich.Furthermore, winches for delivery hoses, hydraulic hoses or electrical cables can be used. In particular with delivery hoses with a relatively large hose diameter, a clean hose winding is decisive for the wear.
Für eine hohe Langlebigkeit ist eine saubere Wicklung auf der Trommel maßgeblich. Hierzu ist es bekannt, die Trommel zu verschwenken, um einen gewünschten Einlaufwinkel des Schlauches oder Seiles einzustellen. Der Einlauf ist auch für eine saubere Wicklung auf der Trommel wichtig, was wiederum Einfluss auf den Verschleiß hat.For a long service life, a clean winding on the drum is decisive. For this purpose, it is known to pivot the drum to set a desired inlet angle of the hose or rope. The inlet is also important for a clean winding on the drum, which in turn has an influence on the wear.

Aufgabe der Erfindung ist es, eine Winde mit einer aktiv verschwenkbaren Trommel bereitzustellen, die kompakt und platzsparend angeordnet ist und zuverlässig arbeitet. The object of the invention is to provide a winch with an actively pivotable drum, which is compact and space-saving and works reliably.
Die Erfindung löst die Aufgabe durch eine Winde mit den Merkmalen des Anspruchs 1. Bevorzugte Ausführungsformen sind in den jeweils abhängigen Ansprüchen angegeben.The invention solves the problem by a winch with the features of
Die erfindungsgemäße Winde zeichnet sich unter anderem dadurch aus, dass die Schwenkachse innerhalb der Trommel verläuft, und der Stellantrieb zumindest teilweise innerhalb der Trommel angeordnet ist.The winch according to the invention is characterized inter alia by the fact that the pivot axis extends within the drum, and the actuator is at least partially disposed within the drum.
Ein Grundgedanke der Erfindung liegt darin, den Innenraum der Trommel durch Aufnahme verschiedener Elemente, insbesondere des Stellantriebs, auszunutzen. Daraus ergibt sich eine besonders kompakte und platzsparende Anordnung der Winde. Ferner sind die in dem Innenraum der Trommel angeordneten Elemente gegenüber äußeren Störungen, wie mechanischen Einwirkungen und Witterungseinflüssen besonders geschützt und somit einem geringeren Verschleiß ausgesetzt. Dadurch wird die Lebensdauer insbesondere des sensiblen Stellantriebs erhöht, so dass Wartungs- und Reparaturkosten für durch Verschleiß bedingte Ausfälle verringert werden können. Zudem erlaubt der dadurch ermöglichte zuverlässige Betrieb der Winde auch einen längeren durchgehenden Einsatz ohne zeit- und kostenintensive Ausfallzeiten.A basic idea of the invention is to utilize the interior of the drum by receiving various elements, in particular the actuator. This results in a particularly compact and space-saving arrangement of the winds. Further, the arranged in the interior of the drum elements are particularly protected against external disturbances, such as mechanical effects and weather conditions and thus exposed to less wear. As a result, the life of the sensitive actuator in particular is increased, so that maintenance and repair costs for wear-related failures can be reduced. In addition allowed The resulting reliable operation of the winch also allows a longer continuous use without time and costly downtime.
Durch die kompakte und robuste Anordnung der Winde kann diese auch in beengten räumlichen Verhältnissen effektiv zum Einsatz kommen. Insbesondere bietet es sich an, die Winde auf einem mobilen Transportträger mit begrenzten Ausmaßen anzuordnen.Due to the compact and robust arrangement of the winch, it can also be used effectively in confined spaces. In particular, it makes sense to arrange the winch on a mobile transport carrier with limited dimensions.
Die erfindungsgemäße Winde ist insbesondere für Schläuche vorteilhaft, aber auch für alle Arten von Seilen und Elektro- oder Datenkabeln geeignet. Nachfolgend wird zu dem aufzuwickelnden Element der Einfachheit halber auf einen Schlauch Bezug genommen, ohne dass die Erfindung hierauf beschränkt sei.The winch invention is particularly advantageous for hoses, but also suitable for all types of ropes and electrical or data cables. For the sake of simplicity, reference will now be made to a hose for the element to be wound, without the invention being restricted thereto.
Die schwenkbare Lagerung der Trommel um eine Schwenkachse ermöglicht es, einen Einlaufwinkel des Schlauches auf die Trommel weitgehend zu optimieren. In geeigneter Weise kann hierbei der Einlaufwinkel so gewählt oder verändert werden, dass ein besonders zuverlässiges, exaktes Aufspulen bei einer ein- oder mehrlagigen Wicklung und gleichzeitig ein besonders geringer Verschleiß gewährleistet sind.The pivotable mounting of the drum about a pivot axis makes it possible to largely optimize an inlet angle of the tube to the drum. Suitably, in this case, the entry angle can be chosen or changed so that a particularly reliable, accurate winding in a single or multi-layer winding and at the same time a particularly low wear are guaranteed.
Der Stellantrieb kann auf unterschiedliche Arten realisiert werden. Besonders vorteilhaft ist es, wenn der Stellantrieb ein hydraulisches Element, insbesondere einen Hydraulikzylinder, aufweist. Mit einem derartigen Element lassen sich auf kleinstem Raum verhältnismäßig große Kräfte ausüben. Dadurch können auch besonders schwere und voll beladene Trommeln noch zuverlässig bewegt werden. Ferner zeichnen sich Hydraulikzylinder durch eine sehr wartungsfreundliche und zuverlässige Arbeitsweise aus. Alternativ kann der Stellantrieb aber auch pneumatisch oder mit einem elektrischen Linearantrieb, beispielsweise mit einer Zahnstange, betrieben werden.The actuator can be realized in different ways. It is particularly advantageous if the actuator has a hydraulic element, in particular a hydraulic cylinder. With such an element can be exercised in a small space relatively large forces. As a result, particularly heavy and fully loaded drums can still be reliably moved. Furthermore, hydraulic cylinders are characterized by a very maintenance-friendly and reliable operation. Alternatively, however, the actuator can also be operated pneumatically or with an electric linear drive, for example with a toothed rack.
Vorteilhafterweise ist der Stellantrieb einerseits an dem Trommeldrehlager und andererseits an der Stützeinrichtung angelenkt. Dabei kann der Stellantrieb beispielsweise an einer Nabenschreibe des Trommeldrehlagers angelenkt sein. Auf diese Art lässt sich auf besonders einfache Weise eine Schwenkachse realisieren, welche innerhalb der Trommel verläuft. Dabei kann gleichzeitig auch der Stellantrieb günstig innerhalb der Trommel angeordnet werden. Zudem werden dadurch die Wegstrecken, welche der Stellantrieb zum Verschwenken der Trommel bewältigen muss, verringert. Dadurch werden der Energieverbrauch und mögliche Verschleißeffekte reduziert.Advantageously, the actuator is articulated on the one hand to the drum pivot bearing and on the other hand to the support means. In this case, the actuator can be articulated, for example, to a hub write the drum rotary bearing. In this way can be realized in a particularly simple manner, a pivot axis which extends within the drum. In this case, at the same time, the actuator can be conveniently located within the drum. In addition, this reduces the distances that the actuator has to handle for pivoting the drum. This reduces energy consumption and possible wear effects.
Grundsätzlich kann der Winkel zwischen der Schwenkachse und der Drehachse ein spitzer Winkel oder ein stumpfer Winkel sein. Es ist vorteilhaft, wenn die Schwenkachse quer zur Drehachse gerichtet ist. Geeigneterweise beträgt der Winkel zwischen der Schwenkachse und der Drehachse jedoch etwa 90°. Dies ermöglicht einen symmetrischen Aufbau einer Lagerung der Trommel, der zur Aufnahme von Zugkräften, wie sie beim Betrieb einer Baumaschine auftreten können, besonders gut geeignet ist. Vorzugsweise verläuft die Schwenkachse in etwa senkrecht zu einer Einlaufebene des Schlauches, in der sich der Schlauch insbesondere beim Auf- und/oder beim Abwickeln auf bzw. von der Trommel bewegt. Bei einer derartigen Anordnung kann der Einlaufwinkel bei besonders kleinen Verschwenkungswinkeln der Trommel um die Schwenkachse optimiert werden.In principle, the angle between the pivot axis and the axis of rotation may be an acute angle or an obtuse angle. It is advantageous if the pivot axis is directed transversely to the axis of rotation. Suitably, however, the angle between the pivot axis and the axis of rotation is about 90 °. This allows a symmetrical structure of a bearing of the drum, which is particularly well suited for receiving tensile forces, such as may occur during operation of a construction machine. Preferably, the pivot axis is approximately perpendicular to an inlet plane of the tube, in which the tube, in particular during the up and / or unwinding on or moves from the drum. With such an arrangement, the entry angle can be optimized for particularly small Verschwenkungswinkeln the drum about the pivot axis.
Die erfindungsgemäße Winde zeichnet sich unter anderem dadurch aus, dass die Schwenkachse innerhalb der Trommel verläuft. Eine solche Anordnung kann sehr kompakt und platzsparend ausgeführt werden. Dabei ist das Trommeldrehlager mit der Trommel über ein Schwenkgelenk an einer Stützeinrichtung gelagert. Ein derartiges Schwenkgelenk kann der Aufnahme eines erheblichen Teils der Windenzugkräfte dienen, so dass ein Verschwenken der Trommel um die Schwenkachse bei besonders geringem Kraftaufwand möglich ist. Bevorzugt sind entlang der Schwenkachse zur Lagerung des Trommeldrehlagers an der Stützeinrichtung zwei Schwenkgelenke vorgesehen.The winch according to the invention is characterized inter alia by the fact that the pivot axis runs inside the drum. Such an arrangement can be made very compact and space-saving. In this case, the drum rotary bearing is mounted with the drum via a pivot joint on a support means. Such a pivot joint can serve to receive a considerable part of the wind tensile forces, so that a pivoting of the drum about the pivot axis is possible with a particularly low expenditure of force. Preferably, two pivot joints are provided along the pivot axis for supporting the drum pivot bearing on the support means.
Erfindungsgemäß ist der Stellantrieb zumindest teilweise innerhalb der Trommel angeordnet. Eine solche Anordnung erlaubt einen besonders kompakten Aufbau der Winde bei einem besonderen Schutz des empfindlichen Stellantriebs vor äußeren mechanischen Einflüssen.According to the invention, the actuator is at least partially disposed within the drum. Such an arrangement allows a particularly compact construction of the winch with a special protection of the sensitive actuator from external mechanical influences.
Nach der Erfindung ist es ferner zweckmäßig, dass eine Verschwenkungsmesseinrichtung zur Messung einer Verschwenkung, insbesondere eines Verschwenkungswinkels, der Trommel gegenüber der Stützeinrichtung vorgesehen ist. Geeigneterweise weist die Verschwenkungsmesseinrichtung dabei einen Stellwertgeber und/oder einen Inkrementalgeber auf.According to the invention, it is also expedient that a pivoting measuring device is provided for measuring a pivoting, in particular a pivot angle, of the drum with respect to the support device. Suitably, the Verschwenkungsmesseinrichtung has a position encoder and / or an incremental encoder.
Der erfindungsgemäß vorgesehene Stellantrieb zum aktiven Verschwenken der Trommel in die Schwenkachse gewährleistet ein besonders zuverlässiges Auf- und/oder Abwickeln bei geringem Verschleiß.The inventively provided actuator for actively pivoting the drum in the pivot axis ensures a particularly reliable up and / or unwinding with little wear.
Grundsätzlich kann der Stellantrieb beispielsweise ein Getriebe aufweisen, das eine Neigung des Mastes mechanisch in einen Verschwenkungswinkel umsetzt. Besonders geeignet ist es jedoch, dass der Stellantrieb mindestens einen Hydraulikzylinder aufweist, der einerseits an einer Nabenscheibe des Trommeldrehlagers und andererseits an der Stützeinrichtung angelenkt sein kann. Hiermit wird ein besonders zuverlässiger und wartungsarmer Stellantrieb zur Verfügung gestellt. Bevorzugt weist der Stellantrieb zwei Hydraulikzylinder auf, die diametral gegenüberliegend jeweils an der Nabenscheibe des Trommeldrehlagers und an der Stützeinrichtung angelenkt sind. Eine solche diametrale Anordnung, insbesondere gegeneinander wirkender Hydraulikzylinder, ermöglicht ein besonders zuverlässiges und sicheres Verschwenken der Trommel bei hohen Zugkräften.In principle, the actuator may, for example, have a gear that mechanically converts an inclination of the mast into a pivoting angle. It is particularly suitable, however, that the actuator has at least one hydraulic cylinder, which may be hinged on the one hand to a hub disc of the drum pivot bearing and on the other hand to the support means. This provides a particularly reliable and low-maintenance actuator. Preferably, the actuator on two hydraulic cylinders, which are hinged diametrically opposite each of the hub disc of the drum pivot bearing and on the support means. Such a diametrical arrangement, in particular against each other acting hydraulic cylinder, allows a particularly reliable and safe pivoting of the drum at high tensile forces.
Eine besonders brauchbare Ausführungsform einer erfindungsgemäßen Winde ist dadurch gekennzeichnet, dass eine Längenmesseinrichtung zur Messung einer von der Trommel auf- und/oder abgewickelten Schlauchlänge vorgesehen ist. Bei bekannten Abmessungen der Winde und/oder des Schlauches kann aus einer solchen Längenmessung auf die Position einer anstehenden Wicklung, d.h. eines Einlaufpunktes, bezüglich einer Längsachse der Trommel geschlossen werden. Hieraus wiederum kann der momentan optimale Verschwenkungswinkel ermittelt werden und die Trommel über den Stellantrieb entsprechend verschwenkt werden. Somit kann ein besonders verschleißarmes Wickeln auch bei besonders breiten Trommeln erreicht werden.A particularly useful embodiment of a winch according to the invention is characterized in that a length measuring device is provided for measuring a hose length wound up and / or unwound from the drum. With known dimensions of the winch and / or the hose, such length measurement may determine the position of a pending winding, i. an inlet point, to be closed with respect to a longitudinal axis of the drum. From this, in turn, the currently optimal pivoting angle can be determined and the drum are pivoted via the actuator accordingly. Thus, a particularly low-wear winding can be achieved even with very wide drums.
Ein besonders präzises Verschwenken der Trommel wird gemäß einer Weiterbildung der Erfindung schließlich dadurch ermöglicht, dass eine Steuereinrichtung zur Steuerung des Stellantriebs vorgesehen ist, die insbesondere mit der Verschwenkungsmesseinrichtung in Verbindung steht. Für eine besonders wirkungsvolle Optimierung des Einlaufwinkels kann die Verschwenkungsmesseinrichtung alternativ oder zusätzlich auch mit der Längenmesseinrichtung in Verbindung stehen.A particularly precise pivoting of the drum is finally made possible according to an embodiment of the invention in that a control device is provided for controlling the actuator, which is in particular connected to the Verschwenkungsmesseinrichtung. For a particularly effective optimization of the entry angle, the Verschwenkungsmesseinrichtung may alternatively or additionally be in communication with the length measuring device.
Bei der erfindungsgemäßen Winde handelt es sich vorteilhafterweise um eine Freilaufwinde oder eine Freifallwinde mit Restzug und/oder Schleppseilautomatik.The winch according to the invention is advantageously a freewheel winch or a freefall winch with residual draw and / or automatic tow rope.
Es ist vorteilhaft, wenn die Stützeinrichtung einen C-förmigen Querschnitt mit zwei Haltearmen aufweist, an denen über je einen Schwenkbolzen das Trommeldrehlager gehalten ist. Mit dieser Anordnung lässt sich bei geringem Materialaufwand ein sehr stabiler Aufbau der Winde realisieren. An dem offenen Bereich der Stützeinrichtung lässt sich der Schlauch besonders einfach herausführen. Die beiden Haltearme, die über je einen Schwenkbolzen an der Nabenscheibe des Trommeldrehlagers angelenkt sind, gewährleisten eine gleichmäßige Verteilung der mechanischen Belastungen auf die gesamte Fläche der Nabenscheibe. Dadurch werden Spannungszustände, die zu Defekten führen können, reduziert. Die Anordnung der beiden Schwenkbolzen zur Bildung der Schwenkgelenke und einer Anlenkung an der Nabenscheibe einerseits sowie an der Stützeinrichtung andererseits, erlauben einen Verlauf der Schwenkachse innerhalb der Trommel, so dass die empfindlichen Schwenkgelenke gegen äußere Einwirkungen weitgehend abgeschirmt sind und deren Zuverlässigkeit erhöht wird.It is advantageous if the support means has a C-shaped cross-section with two retaining arms, on each of which a pivot pin, the drum pivot bearing is held. With this arrangement, a very stable construction of the winch can be realized at low cost of materials. At the open area of the support the hose is particularly easy to take out. The two retaining arms, which are articulated via a respective pivot pin on the hub disc of the drum rotary bearing, ensure a uniform distribution of the mechanical loads on the entire surface of the hub disc. This reduces stress conditions that can lead to defects. The arrangement of the two pivot pins for forming the pivot joints and an articulation on the hub disc on the one hand and on the support means on the other hand, allow a course of the pivot axis within the drum, so that the sensitive pivot joints are largely shielded from external influences and their reliability is increased.
Es ist bevorzugt, wenn ein Schlauch- oder Kabelanschluss vorgesehen ist, welcher zumindest teilweise im Wesentlichen in der Drehachse der Trommel verläuft. An einem derartigen Anschluss können Schläuche zum Fördern von fluiden Medien, beispielsweise von Suspensionen, oder zur Versorgung mit Hydraulik- oder Kühlflüssigkeit angebunden werden. Auch der Anschluss von Kabeln zur Informationsübertragung oder zur elektrischen Versorgung ist möglich. Eine sogenannte Drehdurchführung sorgt für eine zuverlässige Verbindung zwischen dem feststehenden und dem rotierenden Teil.It is preferred if a hose or cable connection is provided, which extends at least partially substantially in the axis of rotation of the drum. Hoses for conveying fluid media, for example suspensions, or for supplying hydraulic or cooling fluid can be connected to such a connection. The connection of cables for information transmission or for electrical supply is possible. A so-called rotary feedthrough ensures a reliable connection between the fixed and the rotating part.
Durch die Anordnung axial zur Drehachse der Trommel kann selbst bei einer weiteren Drehung der Trommel keine Verdrillung des angeschlossenen Schlauches oder Kabels erfolgen. Ferner ist ein Anschluss an dieser Position von einem Monteur besonders leicht zu erreichen und erleichtert damit die Anbindung entsprechender Leitungen oder Vorrichtungen.By arranging axially to the axis of rotation of the drum, no twisting of the connected hose or cable can take place even with a further rotation of the drum. Furthermore, a connection to this position is particularly easy to reach by a fitter and thus facilitates the connection of corresponding lines or devices.
Hinsichtlich der Baumaschine ist die Erfindung dadurch gekennzeichnet, dass eine erfindungsgemäße Winde vorgesehen ist.With regard to the construction machine, the invention is characterized in that a winch according to the invention is provided.
Besonders vorteilhaft ist dabei die Winde zum Betätigen eines Seiles zum Tragen eines Bodenbearbeitungswerkzeuges oder zum Tragen eines Schlauches bzw. Kabels zum Fördern von Material oder zur hydraulischen bzw. elektrischen Versorgung vorgesehen.Particularly advantageous is the winch for operating a rope for carrying a tillage tool or for carrying a hose or cable for conveying material or for hydraulic or electrical supply provided.
Eine Weiterbildung einer erfindungsgemäßen Baumaschine besteht darin, dass eine Neigeeinrichtung vorgesehen ist, mit der ein Mast gegenüber einem Grundkörper quer, insbesondere bezüglich einer Verlaufrichtung des Schlauches und/oder einer durch den Mast und den Grundkörper verlaufenden Achse, neigbar ist. Eine derartige Neigeeinrichtung erlaubt es, den Mast gegenüber dem Grundkörper mit einem Querneigungswinkel von bis zu 10°, bevorzugt bis zu 5°, zu neigen und Bohrungen und gegebenenfalls Pfähle mit einer entsprechenden Neigung gegenüber der Horizontalen herzustellen.A development of a construction machine according to the invention is that a tilting device is provided, with a mast with respect to a base transversely, in particular with respect to a direction of the hose and / or an axis extending through the mast and the base body, tilted. Such a tilting device allows the mast with respect to the main body with a bank angle of up to 10 °, preferably up to 5 °, incline and make holes and optionally piles with a corresponding inclination to the horizontal.
Nach der Erfindung ist es ferner bevorzugt, dass eine Neigungsmesseinrichtung zur Messung einer Querneigung des Mastes bezüglich des Grundkörpers vorgesehen ist, die mit einer Steuereinrichtung eines Stellantriebs der Winde in Verbindung steht, wobei der Stellantrieb zum erfindungsgemäßen Verschwenken der Trommel dienen kann. Hierdurch wird ein Querneigungswinkel-abhängiges Verschwenken der Trommel um eine Schwenkachse derart ermöglicht, dass eine Biegebeanspruchung des Seils beim Einlauf in die Trommel weitestgehend reduziert ist.According to the invention, it is further preferred that a tilt measuring device is provided for measuring a transverse inclination of the mast with respect to the main body, which is connected to a control device of an actuator of the winch, wherein the actuator can serve for pivoting the drum according to the invention. As a result, a banking angle-dependent pivoting of the drum about a pivot axis is made possible in such a way that a bending stress of the rope as it enters the drum is largely reduced.
Um besonders große Zugkräfte bereitstellen zu können, ist es erfindungsgemäß bevorzugt, dass die Winde am Grundkörper angeordnet ist. Geeigneterweise ist die Winde an einem Teil des Grundkörpers angeordnet, der nicht durch die Neigeeinrichtung gegenüber dem Grundkörper neigbar ist.To be able to provide particularly large tensile forces, it is inventively preferred that the winch is arranged on the base body. Suitably, the winch is disposed on a part of the base body which is not tiltable by the tilting device relative to the base body.
