Die Erfindung betrifft eine im wesentlichen kardanische Haltevorrichtung für ein in Arbeitsstellung im wesentlichen zwangfrei an einem Ausleger od.dgl., insbesondere am freien Endabschnitt eines Kranarmes aufzuhängendes The invention relates to an essentially gimbal-type holding device for a suspension or the like, which is essentially forcibly in the working position, in particular on the free end section of a crane arm
Arbeitsgerät, insbesondere einen sog. Harvester, also eine Vorrichtung zum Entasten und Schälen von gefällten Bäumen, mit einer ersten horizontalen Pendelachse, die an ihren Achsenden - üblicherweise unter Zwischenschaltung eines Geschirrs - am Ausleger od.dgl. zu halten bzw. zu lagern ist, und an deren freiem mittleren (Achs-)Abschnitt eine nach unten gerichtete Pendelbuchse schwenkbar gelagert ist, an deren gegabeltem unteren Abschnitt eine rechtwinklig zur ersten Pendelachse verlaufende zweite horizontale Working device, in particular a so-called harvester, that is a device for delimbing and peeling felled trees, with a first horizontal pendulum axis, or the like at its axis ends - usually with the interposition of dishes - on the boom. is to be held or stored, and on the free middle (axle) section of a downwardly directed pendulum bush is pivotally mounted, on the bifurcated lower section of a right angle second horizontal axis running to the first pendulum axis

Zum Entasten und Schälen (der Rinde) von Baumstämmen (insbesondere für die Papierindustrie) werden bei der Holzaufbereitung sog. Harvester-Aggregate eingesetzt, mittels derer gefällte Bäume zu entasten und/oder von ihrer Rinde zu For delimbing and peeling (the bark) of tree trunks (in particular for the paper industry), so-called harvester units are used in wood preparation, by means of which the felled trees are delimbed and / or removed from their bark

Diese Harvester-Aggregate werden üblicherweise an einem Ausleger eines verfahrbaren Gerätes, i.a. an einem Kranarm pendelnd angehängt, um sie halten und bei der Holzbearbeitung zwangfrei führen zu können. Dabei hat es sich jedoch gezeigt, daß es bei einer frei pendelnden Aufhängung eines HarvesterAggregates zu erheblichen Holzverlusten kommen kann, wenn es bei der Holzbearbeitung zu erheblichen schwingenden Pendelbewegungen kommt, weil dabei die Bearbeitungswerkzeuge des betreffenden Harvester-Aggregates zu tief in das Nutzholz eindringen können, Rinde in das Nutzholz eindrücken, so daß dieses für hochqualitative Papiere nicht mehr verwendbar ist etc. These harvester heads are usually mounted on a boom of a mobile device, i.a. suspended from a crane arm so that it can be held and guided freely during woodworking. It has been shown, however, that with a freely swinging suspension of a harvester head, there can be considerable wood losses if there are significant swinging movements during woodworking, because the processing tools of the relevant harvester head can penetrate too deeply into the timber. Press the bark into the timber so that it can no longer be used for high quality paper etc.
Um diese erheblichen Nachteile zu vermeiden, hat man bei gattungsgemäßen Haltevorrichtungen daher der dem Arbeitsgerät benachbarten (zweiten) Pendelachse eine Pendelschwingungen dämpfende Bremseinrichtung zugeordnet, um In order to avoid these considerable disadvantages, in the case of generic holding devices, a braking device damping pendulum vibrations is assigned to the (second) pendulum axis adjacent to the implement in order to
ein bei der Holzbearbeitung grundsätzlich nicht vermeidbares Pendeln um die zweite Pendelachse, also quer zum an unavoidable swinging around the second swinging axis, i.e. transverse to the
Ausleger, abzubremsen bzw. zu dämpfen, da man davon ausge gangen ist, daß die quer zum Ausleger auftretenden Pendelbewegungen allein oder zumindest im wesentlichen für die oben erwähnten Holzbeschädigungen verantwortlich seien, und daß ein Harvester-Aggregat durch den jeweils zu bearbeitenden Baumstamm selbst hinsichtlich möglicher Pendelbewegungen um die erste horizontale Pendelachse hinreichend geführt sei. Boom to slow down or dampen as you run out of it It has been known that the pendulum movements occurring transversely to the boom are solely or at least essentially responsible for the above-mentioned damage to the wood, and that a harvester head is adequately guided by the tree trunk to be processed, even with regard to possible pendulum movements about the first horizontal pendulum axis.
Es hat sich jedoch gezeigt, daß es auch bei einer Dämpfung bzw. Bremsung von Pendelschwingungen eines HarvesterAggregates um die zweite Pendelachse noch zu erheblichen However, it has been shown that even with damping or braking of pendulum vibrations of a harvester head around the second pendulum axis, it is still too considerable
Holzbeschädigungen und damit entsprechenden Verlusten kommt. Damage to wood and corresponding losses.
Der vorliegenden Erfindung liegt demgemäß die Aufgabe zugrunde, bei einer Haltevorrichtung der eingangs beschriebenen Gattung die oben erwähnten Nachteile möglichst vollständig, zumindest aber weitgehend zu vermeiden, und eine derartige Haltevorrichtung zu schaffen, die möglichst weitgehend in den freien Endabschnitt eines Auslegers (also bspw. eine Kranspitze) zu integrieren ist, wobei sich die erfindungsgemäße Haltevorrichtung insbesondere für kleinere Harvester-Aggregate eignen soll, darüber hinaus aber ersichtlich auch für andere entsprechend aufgehängte Arbeitsgeräte verwendbar ist. Accordingly, the object of the present invention is to avoid the above-mentioned disadvantages as completely as possible, or at least largely, in the case of a holding device of the type described at the outset, and to create such a holding device which, as far as possible, fits into the free end section of a cantilever arm (for example a Crane tip) is to be integrated, the holding device according to the invention should be particularly suitable for smaller harvester units, but it is also evident that it can also be used for other appropriately suspended implements.
Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß auch der ersten Pendelachse eine (zweite) Bremseinrichtung zugeordnet ist, mittels welcher ein Pendeln des Arbeitsgerätes in Längsrichtung des Auslegers um die erste Pendelachse abzubremsen bzw. zu dämpfen ist. The solution to this problem is, according to the invention, that a (second) braking device is also assigned to the first pendulum axis, by means of which a swinging of the implement in the longitudinal direction of the boom about the first pendulum axis can be braked or damped.
Dabei ist die Bremskraft der zweiten Bremseinrichtung bevorzugt einstellbar, um einerseits zwar das ersichtlich erforderliche zwangfreie Führen des Arbeitsgerätes möglichst mühelos realisieren zu können, andererseits aber auch die Bremskraft der zweiten Bremseinrichtung so (stark) einstellen zu können, daß ein Pendeln des Arbeitsgerätes in Längsrichtung des Auslegers praktisch nicht erfolgt bzw. ggf. stark gedämpft bzw. abgebremst wird. The braking force of the second braking device is preferably adjustable so that, on the one hand, it is possible to implement the apparently required forced guidance of the implement as effortlessly as possible, but on the other hand, the braking force of the second braking device can also be set (strongly) so that pendulum of the implement in the longitudinal direction of the boom practically does not take place or, if necessary, is strongly damped or braked.
Bei einer höchst bevorzugten Ausgestaltung der vorliegenden Erfindung ist an beiden Stirnseiten der Pendelbuchse jeweils eine Bremsscheibe angeordnet, die an ihrer anderen Seite an einem Widerlager anliegt, wobei das Widerlager der einen In a most preferred embodiment of the present invention, a brake disc is arranged on both end faces of the pendulum bushing, which abuts an abutment on its other side, the abutment of one
Bremsscheibe ein Teil des Auslegers (also bspw. ein Flansch einer Kranspitze) sein kann, oder aber auch zwischen der Brake disc can be part of the boom (e.g. a flange of a crane tip), or between the
zweiten Seite der ersten Bremsscheibe und dem Ausleger ein second side of the first brake disc and the boom
Druckstück als (Brems-) Widerlager angeordnet sein kann. Pressure piece can be arranged as a (brake) abutment.
Die an der anderen (zweiten) Stirnseite der Pendelbuchse The one on the other (second) end of the pendulum bush
anliegende Bremsscheibe wirkt bevorzugt mit einem (zweiten) Druckstück zusammen, welches axial beweglich angeordnet und mittels seiner Federanordnung an die zweite Bremsscheibe The adjacent brake disc preferably interacts with a (second) thrust piece which is arranged to be axially movable and by means of its spring arrangement on the second brake disc
anzudrücken ist, wobei sich für derartige Federanordnungen is to be pressed, with such spring arrangements

Bei dem Ausleger 2 hande es sich übrigens um die Spitze eines Krans. E The drawing shows a holding device, designated as a whole by 1, for a working device 3 which is essentially forced to hang freely on a boom 2 in the working position and which is a relatively small harvester unit, of which only an upper section can be seen in the drawing. By the way, the jib 2 is the tip of a crane.
Die Haltevorrichtung 1 weist eine erste horizontale Pendelachse 4 auf, die mit ihren Achsenden 5 am Ausleger 2 gelager ist. Am freien mittleren Abschnitt der ersten Pendelachse 4 ist eine nach unten gerichtete Pendelbuchse 6 schwenkbar gelagert, an deren gegabeltem unteren Abschnitt 7 eine recht winklig zur ersten Pendelachse 4 verlaufende zweite horizontale Pendelachse 8 mit ihren Achsenden gelagert ist, wobei am mittleren Abschnitt der zweiten Pendelachse 8 ein mit dem Arbeitsgerät 3 zu verbindendes Auge 9 gelagert ist. The holding device 1 has a first horizontal pendulum axis 4, which is supported with its axis ends 5 on the boom 2. On the free middle section of the first pendulum axis 4, a downwardly directed pendulum bushing 6 is pivotally mounted, on the forked lower section 7 of which a second horizontal pendulum axis 8, which runs at a right angle to the first pendulum axis 4, is supported with its axis ends, the middle section of the second pendulum axis 8 an eye 9 to be connected to the implement 3 is mounted.
Der zweiten Pendelachse 8 ist eine (erste) Bremseinrichtung 10 zugeordnet, mittels welcher ein Pendeln des Arbeitsgerätes 3 um die zweite Pendelachse 8 und damit quer zum Ausleger 2 abzubremsen bzw. zu dämpfen ist. Diese der zweite Pendelachse 8 zugeordnete (erste) Bremseinrichtung 10 weist zwei außenliegende Bremsscheiben 11 auf, die jeweils mit einer Widerlagerplatte 12 zusammenwirken, wobei die The second pendulum axis 8 is assigned a (first) braking device 10, by means of which a swinging of the implement 3 around the second pendulum axis 8 and thus across the boom 2 is braked or damped. This (first) braking device 10 assigned to the second pendulum axis 8 has two external brake disks 11, each of which cooperate with an abutment plate 12, the
eine Widerlagerplatte 12 an dem Abschnitt 7 und die andere Widerlagerplatte an einem zwischen der Haltevorrichtung 1 un dem Arbeitsgerät 3 angeordneten Rotator 13 gehalten ist, der sicherstellt, daß das Arbeitsgerät 3 sich um eine Vertikalachse 14 drehen kann. one abutment plate 12 is held on the section 7 and the other abutment plate is held on a rotator 13 arranged between the holding device 1 and the implement 3, which ensures that the implement 3 can rotate about a vertical axis 14.
Erfindungsgemäß ist auch der ersten horizontalen Pendelachse 4 eine (zweite) Bremseinrichtung zugeordnet, mittels welcher ein Pendeln des Arbeitsgerätes 3 in Längsrichtung des Auslegers und damit um die erste Pendelachse 4 abzubremsen bzw. zu dämpfen ist, wobei die Bremskraft der zweiten Bremseinrichtung einstellbar ist, wie noch im einzelnen beschrieben wird. According to the invention, the first horizontal oscillating axis 4 is also assigned a (second) braking device, by means of which an oscillation of the implement 3 in the longitudinal direction of the boom and thus about the first oscillating axis 4 is braked or is damped, the braking force of the second braking device being adjustable, as will be described in detail.
Hierzu ist an der einen (ersten) Stirnseite 15 der Pendelbuchse 6 eine erste Bremsscheibe 16 angeordnet, die an der ersten Stirnseite 15 der Pendelbuchse 6 mit ihrer einen For this purpose, a first brake disk 16 is arranged on one (first) end face 15 of the pendulum bushing 6, the one on the first end face 15 of the pendulum bushing 6

Dabei sitzen die Tellerfedern 23 auf einem Endabschnitt der ersten Pendelachse 4, wobei der mit den Tellerfedern 23 bestückte Endabschnitt 5' mit einem Außengewinde versehen ist und auf dem Gewindeabschnitt 5' der ersten Pendelachse 4 eine Einstellmutter 24 zum Einstellen der auf das zweite On the other (second) end face 19 of the pendulum bushing 6 there is a second brake disc 20, which cooperates with its other (second) side 21 with a second pressure piece 22 which is arranged to be axially movable and is to be pressed against the second brake disc 20 by means of two plate springs 23 . The plate springs 23 are seated on an end section of the first pendulum axis 4, the end section 5 ′ equipped with the plate springs 23 being provided with an external thread and on the threaded section 5 ′ of the first pendulum axis 4 an adjusting nut 24 for adjusting the to the second

Obwohl das Arbeitsgerät 3 ersichtlich gleichsam kardanisch an der Kranspitze (= Ausleger) 2 aufgehängt ist und sich Although the implement 3 can be seen, as it were, gimbally suspended from the tip of the crane (= jib) 2 and itself
- aufgrund des Rotators 13 - nicht nur um die Vertikalachse 14 drehen kann, sondern auch um beide rechtwinklig zueinander verlaufende, horizontale Pedelachsen 4 und 8 zwangfrei beweglich ist, kommt es bei Einsatz der erfindungsgemäßen Haltevorrichtung 1 in beiden rechtwinklig zueinander stehenden Richtungen praktisch nicht mehr zu einer schädlichen Pendelschwingung, so daß die oben beschriebenen Holzverluste damit zu vermeiden sind und darüber hinaus ein erheblich leichteres Arbeiten für die Bedienungspersonen gewährleistet ist, weil diese die Dämpf- bzw. Bremswirkung so einstellen können, daß einerseits zwar schädliche Pendelschwingungen praktisch aus geschlossen sind, daß andererseits aber eine noch weitgehen mühelose freie Beweglichkeit des Arbeitsgerätes 3 bei der Holzbearbeitung möglich ist. - Due to the rotator 13 - not only can rotate about the vertical axis 14, but can also be freely moved about both horizontal pedel axes 4 and 8 running at right angles to one another, the holding device 1 according to the invention practically no longer occurs in both directions perpendicular to one another a harmful pendulum vibration, so that the wood losses described above can thus be avoided and, in addition, considerably easier work for the operators is ensured because they can adjust the damping or braking effect in such a way that on the one hand harmful pendulum vibrations are practically closed, but on the other hand a largely effortless free mobility of the implement 3 in woodworking is possible.
Da die erfindungsgemäße Haltevorrichtung 1 ersichtlich wenigstens zum großen Teil ohne weiteres in eine Kranspitze od.dgl. integrierbar ist, benötigt sie wenig (zusätzliche) Bauhöhe und erlaubt überdies insbesondere auch einen höchst vorteilhaften Einsatz bei kleineren Harvester-Aggregaten, bei denen sich die oben erwähnten Nachteile bisher besonders gravierend bemerkbar gemacht haben. Since the holding device 1 according to the invention can be seen at least for the most part in a crane tip or the like. can be integrated, it requires little (additional) overall height and, moreover, also permits, in particular, highly advantageous use in smaller harvester units in which the disadvantages mentioned above have so far been particularly noticeable.
