Definitions
- the invention relates to a winch according to the preamble of patent claim 1.
- Winches are used in many fields of application, ranging from operations on towing services to sol chen sail during gliding. In particular, they are also used as conveyor hoists, at events and in stage technology.
- a conventional winch for this use consists of a cable drum on which a rope or a number of ropes is wound in one or more layers.
- the cable drum is rotatably mounted about a drum axis, which is held by a frame or support, which is usually attached to the ground.
- An adjacent or in the cable drum arranged drive usually an electric motor, rotates the cable drum via a corresponding gear and thus moves a load attached to the rope by the rope is unwound or wound up.
- the unwinding and winding of the rope is often also using additional facilities that provide a regular winding.
- the cable drum can also be brought to a standstill with a brake to prevent a crash of the load in case of failure of the engine. This is especially true for securing in the stage and event area, where the brake is designed for further safety as a double brake.
- single-stranded or multi-strand winches can be used in combination with a fixedly positioned pulley, in which case the pulley to the cable drum must have a sufficient distance to ensure trouble-free and standard-compliant winding the rope to the cable drum.
- multi-strand winches are used with direct rope outlet in combination with a bottom block, each two strands of rope are wound against each other.
- the load does not change its position orthogonal to the stroke direction.
- the winches per winding turn can be moved to the appropriate winding pitch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
- single-stranded and multi-strand winches can be used in which the pulleys or rope rollers of the winding device are shifted per winding turn to the corresponding winding pitch. In this case, not the whole winch, but only the pulley is moved within the winch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
- an embodiment with a vertical cable outlet is also to be moved horizontally in order to be able either to shift the load or to be able to use the hoist in different positions, this is achieved in two ways: Either a standing on the ground or hanging on the ceiling landing gear is provided with more than two rollers or guides, or a Unterflanschfahrtechnik.
- the method using a Unterflanschfahrtechnik is considered economically advantageous and is therefore by the manufacturers of standard hoists, such as. B. chain hoists and winches widely used.
- Cable winches according to the above examples with a vertical cable outlet also require in the installation on the ground in operation due to the required distance between the cable drum on the one hand and the pulley on the other hand, a relatively large footprint, so that a close arrangement of the individual lifting equipment is not possible.
- a winch of the type mentioned above has become known, wherein a horizontally arranged winch is provided, of which a rope of a plurality of pulleys and a cable hook attached to the end are guided to a center of gravity to no load or load in a horizontal State.
- the object of the invention is therefore to provide a winch with praxisförmigem substantially vertical cable outlet, which can be made compact and can be moved with the least possible load on the chassis.
- the winch according to the invention has the advantage that the center of gravity of the winch from its own weight and payload, regardless of the attached load and the load position, essentially changes only by the weight of the rope to be wound. Due to the fact that the cable guide device has a winding device with a deflection roller, which guides the cable to the point of departure for the vertical cable outlet, the cable guide device ensures the fixation of the point of departure for the vertical cable outlet and at the same time for a uniform winding of the cable. In this case, a particularly compact design is possible, wherein the winding device can take on both tasks.
- the winch according to the invention advantageously no bulky pulleys are required, which would hinder a close erection.
- the compensated with respect to the forces acting arrangement of the elements of the winch prevent the suspension and in particular the soft against torsion, serving as a lane I-profiles of a Unterflanschfahrtechniks be twisted, which otherwise it can lead to a disability of the operation and damage.
- the vertical arrangement of the cable drum regardless of the balanced arrangement has the advantage that at a small cable drum diameter, the weight of the cable drum and the drive components, in particular the transmission, is low and that nevertheless the ground contact surface is compact by the vertical arrangement of the cable drum.
- a compact and lightweight winch can be realized in this new for mobile NOTEzugwinden construction.
- the solution according to the invention is based on the idea, in particular to pay attention to the center of gravity of the winch and to specify this in a suitable manner.
- This emphasis of dead weight and payload should namely, regardless of the load and the load position essentially change only by the weight of the rope to be wound. This applies at least in one direction transversely to an I-beam longitudinal axis located above it.
- Such a design of the winch according to the invention with almost unchanged center of gravity also allows horizontal non-movable use, so without a chassis, a simple, economical and suspension mounting of the hoist, as in the support structure no or at least almost no moments are passed. This also allows a compact design of the hoist with a very small footprint during operation.
- this weight is relatively small in relation to the total weight of the other components. If no fluctuating loads are present and there is a predetermined winding state of the rope, then one comes very close to the ideal state that no moments are exerted by the winch on the corresponding chassis.
- the arrangement of the elements of the winch is provided on the support structure so that at a predetermined MewicklungsSullivan, for example in a half-wound rope, the weight components of the elements orthogonal to the axis of the departure point for the vertical Cable outlet are fully compensated.
- the common support structure is provided on its upper side with min least one suspension lug, the bore for receiving a suspension device is located on the axis of the vertical cable outlet.
- the weight components of the balanced winch are accommodated at a particularly suitable location.
- the support structure has a plurality of suspension lugs on its upper side, wherein the holes for receiving suspension devices are arranged so that the winch regardless of the load and the load position at least about an axis, in particular the I-beam longitudinal axis balanced.
- the holes will be symmetrical to the axis of the vertical cable outlet.
- the cable drum can be arranged horizontally in operation, wherein the cable guide device has a winding device and at least one guide roller, which lead the rope to the departure point for the vertical cable outlet.
- FIG. 1 shows the winch according to the invention with vertically arranged cable drum.
- the cable drum 1 is rotatably mounted in a unitary support structure 6 in the form of a frame or a frame.
- the drive unit 4 which is formed for example in the form of a slip-on with motor, brake and encoder.
- the torque applied to the drive is introduced into the frame 6 via a torque support, which may be provided with an electronic load measuring device. Further details of such a drive are not relevant in the present case and are familiar to the person skilled in the art.
- the cable drum 1 is arranged vertically.
- the winding device 2 is guided synchronously with the cable outlet on the cable drum 1 in the guide 3 in order to redirect the rope to a punctiform cable outlet 9.
- punctiform rope outlet is to be understood that the cable outlet does not migrate during operation, in particular does not shift orthogonal to the vertical stroke direction during the winding process.
- the drive unit 4 acts on the one end of the drive shaft of the cable drum 1 and generates around the cable outlet 9 a counter-torque to the weight of the cable drum 1.
- a control device 7 is provided in this case next to the cable drum 1 and arranged so that the weight based on the punctiform rope outlet 9 is balanced.
- reference numeral 8 At the bottom of the frame 6 can be seen at reference numeral 8, a ground contact surface or ground contact feet, which are not shown in detail.
- the essential aspect is that the weights of all elements of the winch, so the cable drum 1, the drive unit 4 and the controller 7 and any other components of the winch are distributed around the axis of substantially vertical cable outlet 9 so symmetrical that the focus in the level of the cable axis of the cable outlet 9 is located or in the cable axis of the cable outlet 9 itself.
- FIG. 1 can be seen at the top of the support structure 6 is a schematically indicated tab 5 with a bore which serves to receive a suspension device for the winch. It can be seen that this hole is located in the vertical axis of the cable outlet 9 to accommodate the balanced with respect to the gravity components winch and hang if necessary.
- a plurality of such tabs 5 may be provided at the top of the support structure 6, which are formed with corresponding through holes, which serve to receive a suspension. Such holes are then arranged so that at least in one direction, the winch is balanced regardless of the load and the load position.
- the holes are mounted symmetrically to the axis of the vertical cable outlet 9, so that in the suspension of the winch turn the symmetrical with respect to the gravity components or balanced arrangement is not disturbed and the acting loads can be absorbed evenly.
- the balance may be aligned to a predetermined deployment condition. For example, if a winch carries loads at a certain height during operation, it may be advantageous to design the winch from the outset so that at this (average) height the weight of the rope 12 is also balanced.
- the steep 12 is guided by the winding device 2 directly via corresponding pulleys to punctiform, vertical cable outlet 9, so that the cable outlet 9 does not migrate orthogonal to the stroke direction during the winding process.
- All components of the winch including the necessary electronics and control are arranged so that the center of gravity of all components, apart from the weight of the rope to be wound 12 are substantially balanced around the vertical cable outlet 9.

Abstract
Description
Die Erfindung betrifft eine Seilwinde gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a winch according to the preamble of
Seilwinden werden in zahlreichen Anwendungsfeldern eingesetzt, die von Einsätzen bei Abschleppdiensten bis zu sol chen beim Segelflug reichen. Speziell finden sie auch als Fördertechnik-Hebezeuge, bei Veranstaltungen und in der Bühnentechnik Verwendung.Winches are used in many fields of application, ranging from operations on towing services to sol chen sail during gliding. In particular, they are also used as conveyor hoists, at events and in stage technology.
Eine herkömmliche Seilwinde für diesen Einsatz besteht aus einer Seiltrommel, auf die ein Seil oder eine ganze Anzahl von Seile in einer oder mehreren Lagen aufgewickelt ist. Die Seiltrommel ist dabei um eine Trommelachse drehbar gelagert, die von einem Rahmen oder Träger gehalten wird, der zumeist am Boden befestigt ist. Ein neben oder in der Seiltrommel angeordneter Antrieb, in der Regel ein Elektromotor, dreht die Seiltrommel über ein entsprechendes Getriebe und bewegt somit eine an dem Seil befestigte Last, indem das Seil abgewickelt oder aufgewickelt wird.A conventional winch for this use consists of a cable drum on which a rope or a number of ropes is wound in one or more layers. The cable drum is rotatably mounted about a drum axis, which is held by a frame or support, which is usually attached to the ground. An adjacent or in the cable drum arranged drive, usually an electric motor, rotates the cable drum via a corresponding gear and thus moves a load attached to the rope by the rope is unwound or wound up.
Das Abwickeln und Aufwickeln des Seiles erfolgt häufig auch unter Verwendung von zusätzlichen Einrichtungen, die für eine regelmäßige Wicklung sorgen. Die Seiltrommel kann zusätzlich mit einer Bremse zum Stillstand gebracht werden, um einen Absturz der Last bei Ausfall des Motors zu verhindern. Dies gilt insbesondere zur Sicherung im Bühnen- und Veranstaltungsbereich, wo die Bremse zur weiteren Sicherheit als Doppelbremse ausgelegt ist.The unwinding and winding of the rope is often also using additional facilities that provide a regular winding. The cable drum can also be brought to a standstill with a brake to prevent a crash of the load in case of failure of the engine. This is especially true for securing in the stage and event area, where the brake is designed for further safety as a double brake.
Für das Heben bzw. Ziehen von Lasten ist es sehr oft erforderlich, daß die Last während der Hubbewegung nicht orthogonal zum Seil wandert. Dies kann auf verschiedene Arten erreicht werden.For the lifting or pulling of loads, it is very often required that the load is not orthogonal during the lifting movement wanders to the rope. This can be achieved in several ways.
So können einsträngige oder mehrsträngige Seilwinden in Kombination mit einer fest positionierten Seilrolle verwendet werden, wobei dann die Seilrolle zur Seiltrommel einen ausreichen großen Abstand haben muß, um ein störungsfreies und normkonformes Wickeln des Seiles an der Seiltrommel sicherzustellen.Thus, single-stranded or multi-strand winches can be used in combination with a fixedly positioned pulley, in which case the pulley to the cable drum must have a sufficient distance to ensure trouble-free and standard-compliant winding the rope to the cable drum.
Auch werden mehrsträngige Seilwinden mit direktem Seilabgang in Kombination mit einer Unterflasche verwendet, wobei je zwei Seilstränge gegengleich gewickelt werden. Somit ändert die Last trotz der durch das Wickeln entstehenden Schrägzüge ihre Position orthogonal zur Hubrichtung nicht.Also, multi-strand winches are used with direct rope outlet in combination with a bottom block, each two strands of rope are wound against each other. Thus, despite the oblique trains resulting from the winding, the load does not change its position orthogonal to the stroke direction.
Bei einsträngigen sowie mehrsträngigen Seilwinden mit Verfahreinrichtung und direktem Seilabgang können die Seilwinden pro Wickelgang um die entsprechende Wickelsteigung verschoben werden, so daß insgesamt der Seilabgang und somit die Last in ihrer Position senkrecht zur Hubrichtung bleibt.In single-stranded and multi-strand winches with traversing and direct rope departure the winches per winding turn can be moved to the appropriate winding pitch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
Schließlich können auch einsträngige sowie mehrsträngige Seilwinden verwendet werden, bei denen die Seilrollen bzw. Seilwalzen der Wickeleinrichtung pro Wickelgang um die entsprechende Wickelsteigung verschoben werden. Dabei wird also nicht die ganze Seilwinde, sondern lediglich die Seilrolle innerhalb der Seilwinde verschoben, so daß insgesamt der Seilabgang und damit die Last in ihrer Position senkrecht zur Hubrichtung bleibt.Finally, single-stranded and multi-strand winches can be used in which the pulleys or rope rollers of the winding device are shifted per winding turn to the corresponding winding pitch. In this case, not the whole winch, but only the pulley is moved within the winch, so that overall the cable outlet and thus the load remains in position perpendicular to the stroke direction.
Wenn eine Ausführungsform mit einem vertikalen Seilabgang auch horizontal verfahren werden soll, um entweder die Last zu verschieben oder um das Hebezeug an unterschiedlichen Positionen einsetzen zu können, so wird dies auf zweierlei Weisen erreicht:
Entweder ist ein am Boden stehendes oder an der Decke hängendes Fahrwerk mit mehr als zwei Rollen bzw. Führungen vorgesehen, oder aber ein Unterflanschfahrwerk. Das Verfahren unter Verwendung eines Unterflanschfahrwerk gilt als wirtschaftlich vorteilhaft und wird daher von den Herstellern von Standardhebezeugen, wie z. B. Kettenzügen und Seilwinden weitgehend eingesetzt.If an embodiment with a vertical cable outlet is also to be moved horizontally in order to be able either to shift the load or to be able to use the hoist in different positions, this is achieved in two ways:
Either a standing on the ground or hanging on the ceiling landing gear is provided with more than two rollers or guides, or a Unterflanschfahrwerk. The method using a Unterflanschfahrwerk is considered economically advantageous and is therefore by the manufacturers of standard hoists, such as. B. chain hoists and winches widely used.
Nachteilig ist bei herkömmlichen Anordnungen, daß die Seilwinde dabei die als Fahrbahn dienenden Profile häufig ungleichmäßig belasten und somit der Einsatz von verdreh- bzw. verwindungssteifen Profilen erforderlich ist bzw. die Ausführung des Fahrbahnträgers in Form eines I-profils nicht möglich ist.A disadvantage of conventional arrangements that the winch while the serving as a roadway profiles often load unevenly and thus the use of torsional or torsionally rigid profiles is required or the execution of the roadway carrier in the form of an I-profile is not possible.
Seilwinden gemäß den obigen Beispielen mit einem vertikalen Seilabgang erfordern außerdem bei der Aufstellung am Boden im Betrieb aufgrund des erforderlichen Abstandes zwischen der Seiltrommel einerseits und der Seilrolle andererseits eine relativ große Aufstandsfläche, so daß eine enge Anordnung der einzelnen Hebezeuge nicht möglich ist.Cable winches according to the above examples with a vertical cable outlet also require in the installation on the ground in operation due to the required distance between the cable drum on the one hand and the pulley on the other hand, a relatively large footprint, so that a close arrangement of the individual lifting equipment is not possible.
Aus der
Aufgabe der Erfindung ist es daher, eine Seilwinde mit punktförmigem im wesentlichen vertikalen Seilabgang anzugeben, die kompakt ausgebildet werden kann und sich bei möglichst geringer Belastung des Fahrwerks verfahren läßt.The object of the invention is therefore to provide a winch with punktförmigem substantially vertical cable outlet, which can be made compact and can be moved with the least possible load on the chassis.
Diese Aufgabe wird gemäß der Erfindung in vorteilhafter Weise gelöst durch eine Seilwinde mit den Merkmalen des Unabhängigen Anspruchs 1. Vorteilhafte Weiterbildungen der erfindungsgemäßen Seilwinde sind in den abhängigen Ansprüchen angegeben.This object is achieved according to the invention in an advantageous manner by a winch with the features of the
Die erfindungsgemäße Seilwinde bietet den Vorteil, daß sich der Schwerpunkt der Seilwinde aus Eigengewicht und Nutzlast, unabhängig von der angehängten Last und der Laststellung, im wesentlichen nur durch das Eigengewicht des zu wickelnden Seiles ändert. Dadurch, daß die Seilführungseinrichtung eine Wickeleinrichtung mit einer Umlenkrolle aufweist, die das Seil auf den Abgangspunkt für den vertikalen Seilabgang führt, sorgt die Seilführungseinrichtung zur Fixierung des Abgangspunktes für den vertikalen Seilabgang und gleichzeitig für eine gleichmäßige Wicklung des Seiles. Dabei ist eine besonders kompakte Bauweise möglich, wobei die Wicklungseinrichtung beide Aufgaben übernehmen kann.The winch according to the invention has the advantage that the center of gravity of the winch from its own weight and payload, regardless of the attached load and the load position, essentially changes only by the weight of the rope to be wound. Due to the fact that the cable guide device has a winding device with a deflection roller, which guides the cable to the point of departure for the vertical cable outlet, the cable guide device ensures the fixation of the point of departure for the vertical cable outlet and at the same time for a uniform winding of the cable. In this case, a particularly compact design is possible, wherein the winding device can take on both tasks.
Bei der erfindungsgemäßen Seilwinde sind vorteilhafterweise keine sperrigen Seilrollen erforderlich, die ein enges Aufstellen behindern würden. Zudem kann die im Hinblick auf die wirkenden Kräfte kompensierte Anordnung der Elemente der Seilwinde verhindern, daß die Aufhängung und insbesondere die gegenüber Torsion weichen, als Fahrbahn dienenden I-Profile eines Unterflanschfahrwerks verdreht werden, was sonst zu einer Behinderung des Betriebes und zu Beschädigungen führen kann.In the winch according to the invention advantageously no bulky pulleys are required, which would hinder a close erection. In addition, the compensated with respect to the forces acting arrangement of the elements of the winch prevent the suspension and in particular the soft against torsion, serving as a lane I-profiles of a Unterflanschfahrwerks be twisted, which otherwise it can lead to a disability of the operation and damage.
Die vertikale Anordnung der Seiltrommel hat unabhängig von der ausbalancierten Anordnung den Vorteil, daß bei einem kleinen Seiltrommel-Durchmesser das Eigengewicht der Seiltrommel und der Antriebskomponenten, insbesondere des Getriebes, gering ist und daß durch die vertikale Anordnung der Seiltrommel dennoch die Bodenaufstandsfläche kompakt ist. Somit kann bei dieser für mobile Punktzugwinden neuartigen Bauweise eine kompakte und leichte Seilwinde realisiert werden.The vertical arrangement of the cable drum, regardless of the balanced arrangement has the advantage that at a small cable drum diameter, the weight of the cable drum and the drive components, in particular the transmission, is low and that nevertheless the ground contact surface is compact by the vertical arrangement of the cable drum. Thus, a compact and lightweight winch can be realized in this new for mobile Punktzugwinden construction.
Der erfindungsgemäßen Lösung liegt dabei der Gedanke zugrunde, insbesondere auf den Schwerpunkt der Seilwinde zu achten und diesen in geeigneter Weise vorzugeben. Dieser Schwerpunkt von Eigengewicht und Nutzlast soll sich nämlich unabhängig von der Last und der Laststellung im wesentlichen nur durch das Eigengewicht des zu wickelnden Seiles ändern. Dies gilt zumindest in einer Richtung quer zu einer darüber befindlichen I-Träger-Längsachse.The solution according to the invention is based on the idea, in particular to pay attention to the center of gravity of the winch and to specify this in a suitable manner. This emphasis of dead weight and payload should namely, regardless of the load and the load position essentially change only by the weight of the rope to be wound. This applies at least in one direction transversely to an I-beam longitudinal axis located above it.
Damit die Räder eines darüber angeordneten Unterflaschenlaufwerkes bei allen Lastkombinationen auch einigermaßen gleichmäßig beansprucht werden, soll sich der Schwerpunkt auch in der Längsrichtung des 1-Träger kaum verlagern. Auf diese Weise ist eine gleichmäßige Radlastverteilung des Fahrwerks im Betrieb an einem I-Träger-Untergurtfahrwerk sowie ein sicherer Betrieb bei kleiner Bodenaufstandsfläche möglich.So that the wheels of a lower-mounted disk drive arranged above it are also subjected to a fairly uniform load in all load combinations, the center of gravity should hardly shift even in the longitudinal direction of the 1-beam. In this way, a uniform wheel load distribution of the chassis during operation on an I-beam undercarriage and safe operation at a small ground contact area is possible.
Eine solche Bauform der erfindungsgemäßen Seilwinde mit nahezu unverändertem Schwerpunkt ermöglicht auch im horizontal nicht verschiebbaren Einsatz, also ohne ein Fahrwerk, eine einfache, wirtschaftliche und aufhängbare Montage des Hebezeuges, da in die Tragkonstruktion keine bzw. zumindest nahezu keine Momente ein geleitet werden. Dies ermöglicht ferner eine kompakte Ausführung des Hebezeuges mit einer sehr kleinen Aufstandsfläche bei stehendem Betrieb.Such a design of the winch according to the invention with almost unchanged center of gravity also allows horizontal non-movable use, so without a chassis, a simple, economical and suspension mounting of the hoist, as in the support structure no or at least almost no moments are passed. This also allows a compact design of the hoist with a very small footprint during operation.
Wenn in diesem Zusammenhang gesagt ist, daß der Schwerpunkt im wesentlichen in der Achse des Abgangspunktes für den vertikalen Seilabgang liegt, so ist damit berücksichtigt, daß eine vollständige Kompensation der Querkräfte zwar angestrebt wird, dies aber in der Praxis kaum erreichbar ist. Dies liegt darin, daß das Seil im Betrieb unterschiedlich stark von der Seiltrommel abgewickelt bzw. auf diese aufgewickelt wird und sein Eigengewicht auch eine Rolle spielt.If it is said in this context that the center of gravity is located substantially in the axis of the departure point for the vertical cable outlet, it is taken into account that a complete compensation of the transverse forces is indeed sought, but this is hardly achievable in practice. This is because the rope is unwound from the cable drum during operation or wound up on it and its own weight also plays a role.
Dieses Eigengewicht ist aber im Verhältnis zu dem Gesamtgewicht der anderen Komponenten prozentual relativ klein. Wenn keine schwankenden Lasten vorhanden sind und ein vorgegebener Aufwicklungszustand des Seiles vorliegt, so kommt man dem Idealzustand sehr nahe, daß keine Momente von der Seilwinde auf das entsprechende Fahrwerk ausgeübt werden.However, this weight is relatively small in relation to the total weight of the other components. If no fluctuating loads are present and there is a predetermined winding state of the rope, then one comes very close to the ideal state that no moments are exerted by the winch on the corresponding chassis.
In weiterbildung der erfindungsgemäßen Seilwinde ist daher vorgesehen, daß die Anordnung der Elemente der Seilwinde an der Tragkonstruktion so vorgesehen ist, daß bei einem vorgegebenen Aufwicklungszustand, beispielsweise bei einem halb aufgewickelten Seil, die Gewichtskraft-Komponenten der Elemente orthogonal zur Achse des Abgangspunktes für den vertikalen Seilabgang vollständig kompensiert sind.In further development of the winch according to the invention is therefore intended that the arrangement of the elements of the winch is provided on the support structure so that at a predetermined Aufwicklungszustand, for example in a half-wound rope, the weight components of the elements orthogonal to the axis of the departure point for the vertical Cable outlet are fully compensated.
Dieser Anordnung liegt die Überlegung zugrunde, daß die verschiedenen Betriebsstellungen der Seilwinde sich in der Nähe des Aufwicklungszustandes abspielen werden, in welchem das Seil halb auf der Seiltrommel aufgewickelt ist.This arrangement is based on the consideration that the various operating positions of the winch will play near the Aufwicklungszustandes, in which the rope is half wound on the cable drum.
Zweckmäßigerweise ist bei der erfindungsgemaßen Seilwinde die gemeinsame Tragkonstruktion an ihrer Oberseite mit min destens einer Aufhängelasche versehen, deren Bohrung zur Aufnahme einer Aufhängeeinrichtung auf der Achse des vertikalen Seilabgangs liegt. Auf diese Weise werden die Gewichtskomponenten der ausbalancierten Seilwinde an einer besonders geeigneten Stelle aufgenommen.Appropriately, in the inventive winch, the common support structure is provided on its upper side with min least one suspension lug, the bore for receiving a suspension device is located on the axis of the vertical cable outlet. In this way, the weight components of the balanced winch are accommodated at a particularly suitable location.
Bei einer abgewandelten Ausführungsform der erfindungsgemäßen Seilwinde weist die Tragkonstruktion mehrere Aufhängelaschen an ihrer Oberseite auf, wobei deren Bohrungen zur Aufnahme von Aufhängeeinrichtungen so angeordnet sind, daß die Seilwinde unabhängig von der Last und der Laststellung zumindest um eine Achse, insbesondere die I-Träger-Längsachse ausbalanciert ist. Vorzugsweise werden die Bohrungen symmetrisch zur Achse des vertikalen Seilabganges liegen.In a modified embodiment of the winch according to the invention, the support structure has a plurality of suspension lugs on its upper side, wherein the holes for receiving suspension devices are arranged so that the winch regardless of the load and the load position at least about an axis, in particular the I-beam longitudinal axis balanced. Preferably, the holes will be symmetrical to the axis of the vertical cable outlet.
Auch bei dieser Ausführungsform können aufgrund der ausbalancierten Anordnung der Seilwinde die entsprechenden Kräfte besonders gleichmäßig von einer Aufhängeeinrichtung für die Seilwinde aufgenommen werden.Also in this embodiment, due to the balanced arrangement of the winch, the corresponding forces can be absorbed particularly uniformly by a suspension device for the winch.
Weiters kann die Seiltrommel im Betrieb horizontal angeordnet sein, wobei die Seilführungseinrichtung eine Wickeleinrichtung sowie mindestens eine Umlenkrolle aufweist, die das Seil auf den Abgangspunkt für den vertikalen Seilabgang führen.Furthermore, the cable drum can be arranged horizontally in operation, wherein the cable guide device has a winding device and at least one guide roller, which lead the rope to the departure point for the vertical cable outlet.
Die Erfindung wird nachstehend, auch hinsichtlich weiterer Merkmale und Vorteile, anhand der Beschreibung von Ausführungsbeispielen und unter Bezugnahme auf die beiliegenden Zeichnung näher erläutert.
Wie in
Die Seiltrommel 1 ist in einer einheitlichen Tragkonstruktion 6 in Form eines Gestells oder eines Rahmens drehbar gelagert. An dem einen Ende der Seiltrommel 1 erkennt man die Antriebseinheit 4, die beispielsweise in Form eines Aufsteckgetriebes mit Motor, Bremse und Geber ausgebildet ist. Das am Antrieb anstehende Drehmoment wird über eine Drehmomentenstütze, welche mit einer elektronischen Lastmeßeinrichtung versehen sein kann, in den Rahmen 6 eingeleitet. Weitere Einzelheiten eines derartigen Antriebs sind im vorliegenden Fall nicht von Bedeutung und dem Fachmann auf dem einschlägigen Gebiet geläufig.The
Nachstehend wird die oben erwähnte Seilführungseinrichtung für das Seil 12 näher erläutert. An einer parallel zur Achse der Seiltrommel 1 verlaufenden Führung 3 wird über eine zu der Drehzahl der Seiltrommel 1 synchron laufende Spindel eine Wickeleinrichtung 2 synchron zum Seilabgang an der Seiltrommel 1 bewegt. Die Wickeleinrichtung 2 mit der Führung 3 sorgt somit in bekannter Weise für eine gleichmäßige Wicklung des Seiles 12 auf die Seiltrommel 1 bzw. Abwicklung von der Seiltrommel 1.Hereinafter, the above-mentioned rope guide device for the
Gemäß
Die Antriebseinheit 4 wirkt an dem einen Ende der Antriebswelle der Seiltrommel 1 und erzeugt um den Seilabgang 9 ein Gegenmoment zu dem Eigengewicht der Seiltrommel 1. Eine Steuerungseinrichtung 7 ist in diesem Falle neben der Seiltrommel 1 vorgesehen und so angeordnet, daß das Eigengewicht bezogen auf den punktförmigen Seilabgang 9 ausgeglichen ist. An der Unterseite des Rahmens 6 erkennt man bei dem Bezugszeichen 8 eine Bodenaufstandsfläche bzw. Bodenaufstandsfüße, die nicht näher dargestellt sind.The
Der wesentliche Aspekt besteht darin, daß die Gewichte sämtlicher Elemente der Seilwinde, also der Seiltrommel 1, der Antriebseinheit 4 und der Steuerungseinrichtung 7 sowie etwaiger weiterer Komponenten der Seilwinde um die Achse des im wesentlichen vertikalen Seilabganges 9 derart symmetrisch verteilt sind, daß der Schwerpunkt in der Ebene der Seilachse des Seilabganges 9 liegt bzw. in der Seilachse des Seilabganges 9 selbst liegt.The essential aspect is that the weights of all elements of the winch, so the
Dann wirken im Betrieb der Seilwinde zumindest quer zu einem eventuell darüber angeordneten Fahrbahnträger nämlich ausschließlich Kräfte in Lastrichtung, während Querkräfte oder Momente, welche die Aufhängung oder eine für die Seilwinde vorgesehene Fahrbahn beeinträchtigen könnten, nicht mehr auftreten. Wie bereits erwähnt, ist dies in der Praxis in guter Näherung zu erreichen, wobei geringfügige Ungleichmäßigkeiten in der Praxis aufgrund des Eigengewichtes des Seiles 12 auftreten können. Dies hängt davon ab, wie groß der Gewichtsanteil des Seiles 12 ist, das auf der Seiltrommel 1 aufgewickelt bzw. von dieser abgewickelt ist.Then act in operation of the winch, at least transversely to a possibly disposed above the roadway carrier namely only forces in the load direction, while lateral forces or moments that could affect the suspension or provided for the winch road, no longer occur. As already mentioned, this can be achieved in practice to a good approximation, with slight unevenness in practice may occur due to the weight of the
Die Eigenbewegung der Wickeleinrichtung 3 synchron zur Wicklung ist bei der Wicklung nicht störend, weil sie in der Zugrichtung erfolgt und daher ohne weitere Einrichtungen den vertikalen Seilabgang 9 an einer festen Stelle beläßt.The proper movement of the winding
An dem Grundsatz und den Vorteilen der Anordnung, bei der die Schwerkraftkomponenten der Elemente der Seilwinde kompensiert werden, ändert sich dadurch natürlich nichts. Es müssen lediglich die Seiltrommel, die Antriebseinheit 4, die Steuerungseinrichtung 7 sowie etwaige weitere Elemente der Seilwinde entsprechend der veränderten Position und Stellung der Seiltrommel 1 angepaßt werden, um die erforderliche Kompensation und den gewünschten Schwerpunkt zu erhalten.Of course, this does not change the principle and the advantages of the arrangement in which the components of gravity of the elements of the cable winch are compensated. It only need the cable drum, the
Gemäß
Bei einer nicht dargestellten Ausführungsform einer derartigen Seilwinde können auch mehrere derartige Laschen 5 an der Oberseite der Tragkonstruktion 6 vorgesehen sein, die mit entsprechenden Durchgangsbohrungen ausgebildet sind, welche zur Aufnahme einer Aufhängeeinrichtung dienen. Derartige Bohrungen werden dann so angeordnet, daß zumindest in einer Richtung die Seilwinde unabhängig von der Last und der Laststellung ausbalanciert ist.In an embodiment of such a winch, not shown, a plurality of such tabs 5 may be provided at the top of the
Zweckmäßigerweise werden die Bohrungen symmetrisch zu der Achse des vertikalen Seilabganges 9 angebracht, damit bei der Aufhängung der Seilwinde wiederum die hinsichtlich der Schwerkraftkomponenten symmetrische bzw. ausbalancierte Anordnung nicht gestört wird und die wirkenden Lasten gleichmäßig aufgenommen werden können.Conveniently, the holes are mounted symmetrically to the axis of the
Bei sämtlichen vorstehend beschriebenen Ausführungsformen der Seilwinde kann, um die Variationen durch das Eigengewicht des Seiles 12 in verschiedenen Abwicklungszuständen zumindest teilweise zu berücksichtigen, das Gleichgewicht auf einen festgelegten Abwicklungszustand ausgerichtet werden. Trägt eine Seilwinde im Betrieb beispielsweise hauptsächlich Lasten in einer bestimmten Nutzhöhe, so kann es vorteilhaft sein, die Seilwinde von vornherein so auszulegen, daß bei dieser (durchschnittlichen) Höhe auch das Eigengewicht des Seiles 12 ausgeglichen ist.In all the embodiments of the winch described above, to at least partially take into account the variations in the dead weight of the
Somit wird das Steil 12 von der Wickeleinrichtung 2 direkt über entsprechende Umlenkrollen zum punktförmigen, vertikalen Seilabgang 9 geführt, so daß der Seilabgang 9 während des Wickelvorgangs nicht orthogonal zur Hubrichtung wandert.Thus, the steep 12 is guided by the winding device 2 directly via corresponding pulleys to punctiform,
Sämtliche Komponenten der Seilwinde, einschließlich der erforderlichen Elektronik und Steuerung sind so angeordnet, daß der Schwerpunkt aller Bauteile, abgesehen von dem Eigengewicht des zu wickelnden Seiles 12 im wesentlichen um den vertikalen Seilabgang 9 ausgeglichen sind. Damit werden die einleitend beschriebenen Vorteile gemäß der Erfindung bei sämtlichen Ausführungsformen erreicht.All components of the winch, including the necessary electronics and control are arranged so that the center of gravity of all components, apart from the weight of the rope to be wound 12 are substantially balanced around the
