Description
Die Erfindung betrifft ein Anschlagelement zum Verkoppeln eines Anschlagmittels, wie einen Schäkel, Haken oder Ring, oder eines Hebemittels, wie einem Band, einem Seil, einer Kette oder einem Gurt, mit einem zu transportierenden Gut, wobei das Anschlagelement einen Befestigungsabschnitt besitzt, in den eine länglich geformte Öffnung eingeformt ist, die von der Oberseite des Befestigungsabschnitts zu einer auf der Unterseite des Befestigungsabschnitts ausgebildeten Aufstandfläche führt. Solch ein Anschlagelement ist z.B. aus
Anschlagelemente der hier in Rede stehenden Art weisen üblicherweise einen Befestigungsabschnitt, mit dem sie unmittelbar an dem zu transportierenden Gut befestigt werden, und ein Anschlagsegment auf, mit dem das jeweilige Hebemittel, wie Band, Seil, Kette oder Gurt, durch Knoten oder Schlaufen entweder direkt verbunden werden kann oder aus praktischen und sicherheitstechnischen Erwägungen über ein als Zwischenelement dienendes Anschlagmittel, wie einen Schäkel, einen Haken oder Ring, verbunden werden kann. In die Befestigungsabschnitte sind dabei Öffnungen eingeformt, durch die ein Befestigungsmittel, bei dem es sich typischerweise um eine Schraube oder einen Bolzen handelt, in eine korrespondierende Öffnung am jeweiligen Flansch des zu transportierenden Guts geführt werden kann. Um die Montage und das Ausrichten des Anschlagelements zu vereinfachen, sind die betreffenden Öffnungen in der Regel als Langlochöffnungen so ausgebildet, dass die genaue Winkellage des jeweiligen Anschlagelements vor dem endgültigen Verspannen des jeweiligen Befestigungselements noch einmal justiert werden kann.Stop elements of the type in question here usually have a mounting portion with which they are attached directly to the goods to be transported, and a stop segment on which the respective lifting means, such as tape, rope, chain or belt, by knots or loops either directly can be connected or for practical and safety considerations about serving as an intermediate element stop means, such as a Shackle, a hook or ring, can be connected. In this case, openings are formed in the fastening sections, through which a fastening means, which is typically a screw or a bolt, can be guided into a corresponding opening on the respective flange of the material to be transported. In order to simplify the assembly and alignment of the stop element, the openings in question are usually designed as slot openings so that the exact angular position of the respective stop element can be adjusted again before the final bracing of the respective fastener.
Solche Anschlagmittel werden beispielsweise zum Annheben und Ausrichten großer stählerner, separat vorgefertigter Turmelemente von Windkraftanlagen oder vergleichbar großer Rohre von Pipelines oder desgleichen verwendet. Der Durchmesser solcher jeweils rohrförmigen Elemente ist in der Regel deutlich geringer als deren Länge. Deshalb werden die Elemente liegend zum jeweiligen Standort transportiert.Such slings are used, for example, for lifting and aligning large steel, separately prefabricated tower elements of wind turbines or comparable sized pipes of pipelines or the like. The diameter of such respective tubular elements is generally much smaller than their length. Therefore, the elements are transported horizontally to the respective location.
Im Fall von Turmelementen müssen sie dann am Standort nicht nur von dem zur Beförderung genutzten Schwertransporter, Wagon oder Schiff angehoben und in ihre Endposition eingeschwenkt werden, sondern zusätzlich auch noch von der waagerechten Ausrichtung in eine senkrechte Ausrichtung gedreht werden, so dass sie auf ein Fundament bzw. ein bereits aufgestelltes Turmelement abgestellt werden können.In the case of tower elements, they must then be raised at the site not only by the used for carriage heavy truck, wagon or ship and pivoted to its final position, but also be rotated from the horizontal orientation in a vertical orientation, so that they on a foundation or an already erected tower element can be turned off.
Zum Anheben und Ausrichten werden typischerweise jeweils mindestens zwei Anschlagelemente an den Stirnseiten der Endflansche der rohrförmigen Elemente so befestigt, dass das eine Anschlagelement beispielsweise auf 10 Uhr und das zweite Element auf 2 Uhr montiert ist.For raising and aligning, in each case at least two stop elements are typically fastened to the end faces of the end flanges of the tubular elements such that the one stop element is mounted, for example, at 10 o'clock and the second element at 2 o'clock.
Infolge dieser Anordnung ist die Wirklinie der beim Anheben des Transportguts auf die zum Befestigen des jeweiligen Anschlagelements verwendeten Befestigungsmittel wirkenden Hebekräfte unter einem spitzen Winkel zur Schwerkraftwirkung ausgerichtet. Aufgrund dessen, dass die Befestigungsmittel jeweils in einer länglichen Öffnung des zugeordneten Befestigungsabschnitts des Anschlagelements sitzt, kann es daher im Fall, dass das jeweilige Spannmittel nicht mit ausreichender Kraft angezogen ist, dazu kommen, dass das Anschlagelement unter der Last verrutscht. Nach Überwindung der zwischen dem Anschlagelement und dem jeweiligen Flansch herrschenden Reibung erfolgt dieses Verrutschen vielfach schlagartig, so dass es zu einer gefährlichen plötzlichen Überlastung der Befestigungsmittel durch Querkräfte kommen kann, für die die Befestigungsmittel nicht ausgelegt sind.As a result of this arrangement, the line of action of the lifting forces acting on the fasteners used to lift the cargo to lift the cargo is oriented at an acute angle to the force of gravity. Due to the fact that the fastening means in each case sits in an elongated opening of the associated fastening portion of the stop element, it can therefore happen that the stop element slips under the load in the event that the respective clamping means is not tightened with sufficient force. After overcoming the prevailing between the stopper element and the respective flange friction this slipping takes place many times abruptly, so that it can lead to a dangerous sudden overloading of the fastening means by transverse forces for which the fastening means are not designed.
Vor diesem Hintergrund bestand die Aufgabe der Erfindung darin, ein Anschlagelement zu schaffen, bei dem die Gefahr eines Verrutschens auch unter unzureichender Spannung des jeweiligen Befestigungsmittels minimiert ist. Darüber hinaus sollte ein ein solches Anschlagelement und ein Befestigungselement umfassender Bausatz vorgeschlagen werden, mit dem eine dauerhaft sichere Befestigung des Anschlagelements auch unter ungünstigen Belastungen möglich ist.Against this background, the object of the invention to provide a stop element, in which the risk of slippage is minimized even under insufficient tension of the respective fastener. In addition, a such a stop element and a fastener comprehensive kit should be proposed, with a permanently secure attachment of the stop element is possible even under unfavorable loads.
In Bezug auf das Anschlagelement ist diese Aufgabe durch ein Anschlagelement gelöst worden, das erfindungsgemäß die in Anspruch 1 angegebenen Merkmale aufweist. Vorteilhafte Ausgestaltungen eines solchen Anschlagmittels sind in den auf Anspruch 1 rückbezogenen Ansprüchen angegeben.With respect to the stop element, this object has been achieved by a stop element, which according to the invention has the features specified in
In Bezug auf den Bausatz besteht die erfindungsgemäße Lösung der oben genannten Aufgabe durch die in Anspruch 11 angegebene Kombination aus Anschlagelement und Befestigungselement. Vorteilhafte Ausgestaltungen dieser Lösung sind in den auf Anspruch 11 rückbezogenen Ansprüchen angegeben.With respect to the kit, the solution according to the invention of the above-mentioned object by the specified in
Ein erfindungsgemäßes Anschlagelement besitzt in an sich bekannter Weise mindestens einen Befestigungsabschnitt, in den eine länglich geformte Öffnung eingeformt ist, die von der Oberseite des Befestigungsabschnitts zu einer auf der Unterseite des Befestigungsabschnitts ausgebildeten Anlagefläche führt.A stop element according to the invention has, in a manner known per se, at least one fastening section into which an elongate shaped opening is formed, which leads from the upper side of the fastening section to a contact surface formed on the underside of the fastening section.
Erfindungsgemäß ist nun an dem Befestigungsabschnitt eine in Längsrichtung der länglichen Öffnung des Befestigungsabschnitts ausgerichtete Keilfläche ausgebildet. Diese Keilfläche verläuft in einer Ebene, welche die Längsachse der Öffnung unter einem spitzen Winkel schneidet. Dabei ist die Keilfläche als Abstützung für ein Befestigungsmittel ausgebildet, das zum Verspannen des Anschlagelements an dem zu transportierenden Gut vorgesehen ist.According to the invention, a wedge surface oriented in the longitudinal direction of the elongate opening of the fastening section is now formed on the fastening section. This wedge surface extends in a plane which intersects the longitudinal axis of the opening at an acute angle. In this case, the wedge surface is formed as a support for a fastening means which is provided for bracing the stop element on the goods to be transported.
Die erfindungsgemäß an dem Befestigungsabschnitt des Anschlagelements vorgesehene Keilfläche ist folglich so ausgerichtet, dass die in Längsrichtung der Öffnung des Befestigungsabschnitts und damit quer zum jeweiligen Befestigungsmittel wirkenden Kräfte in Richtung der vom Befestigungsmittel ausgeübten Spannkräfte umgeleitet werden und so zusätzlich zum Halt des Anschlagelements am jeweils zu transportierenden Gut beitragen. Es wird so eine Verkeilung des Anschlagelements erreicht, wodurch ein Verrutschen des Anschlagelements sicher verhindert wird.The inventively provided at the attachment portion of the stopper member wedge surface is thus aligned so that in the longitudinal direction of the opening of the Fixing portion and thus acting transversely to the respective fastening means forces are diverted in the direction of the clamping force exerted by the fastening means and thus contribute in addition to the support of the stop element on the respectively to be transported Good. It is achieved as a keying of the stop element, whereby slipping of the stop element is reliably prevented.
Dementsprechend umfasst bei einer erfindungsgemäßen Kombination aus einem erfindungsgemäß ausgebildeten Anschlagelement und einem Befestigungsmittel zum Verspannen des Anschlagelements an einem zu transportierenden Gut das Befestigungsmittel ein Formelement mit einer Keilfläche, mit der das Befestigungsmittel auf einer Keilfläche des ihm zugeordneten Befestigungsabschnitts des Anschlagelements verschiebbar abgestützt ist.Accordingly, in a combination according to the invention of a stop element designed according to the invention and a fastening means for bracing the stop element on a good to be transported, the fastening means comprises a form element with a wedge surface, with which the fastening means is slidably supported on a wedge surface of its associated attachment portion of the stop element.
Bei dem mit der Keilfläche versehenen Formelement kann es sich beispielsweise um einen gesondert ausgebildeten Absatz eines als einstückig ausgebildetes Befestigungsmittel dienenden Spannelements, wie einer Schraube oder eines Bolzens handeln, der in ausreichender Weise weit von dem Schraubenschaft absteht. Ebenso kann es sich bei dem mit der Keilfläche versehenen Formelement um den Schraubenkopf eines solchen Befestigungsmittels handeln.The shaped element provided with the wedge surface may be, for example, a separately formed shoulder of a clamping element designed as an integral fastening means, such as a screw or a bolt, which projects sufficiently far from the screw shank. Likewise, the shaped element provided with the wedge surface may be the screw head of such a fastening means.
Eine besonders vielseitige und gleichzeitig einfach und sicher handhabbare Ausgestaltung der Erfindung ergibt sich allerdings dann, wenn das Befestigungsmittel ein Spannelement, wie eine Schraube oder ein Bolzen, und als mit der Keilfläche versehenes Formelement ein separat vorgefertigtes Adapterstück umfasst, das eine Stützfläche zum Abstützen des Spannelements sowie eine Durchgangsöffnung aufweist, durch die das Spannelement in die Öffnung des zugeordneten Befestigungsabschnitt einführbar ist.A particularly versatile and at the same time easy and safe to handle embodiment of the invention, however, arises when the fastening means a clamping element, such as a screw or a bolt, and as provided with the wedge-shaped form element comprises a separately prefabricated adapter piece, which has a support surface for supporting the clamping element and a passage opening through which the clamping element is insertable into the opening of the associated attachment portion.
Die Entstehung von ungünstigen, auf das jeweilige Befestigungsmittel wirkenden Querkräften kann dadurch verhindert werden, dass sich gemäß einer ersten Ausgestaltung der Erfindung jeweils eine Keilfläche mit in Bezug auf die Längsachse der länglichen Öffnung des Befestigungsabschnitts gleicher Winkelausrichtung entlang beider Längsseiten der Öffnung erstreckt. Dabei lassen sich optimale Belastungen des Befestigungsmittels bei gleichzeitig minimiertem Raumbedarf des jeweiligen Befestigungsabschnitts des Anschlagelements dadurch erreichen, dass die jeweilige Keilfläche an die längliche Öffnung des Befestigungsabschnitts grenzt.The emergence of unfavorable, acting on the respective fastening means transverse forces can be prevented by extending according to a first embodiment of the invention each have a wedge surface with respect to the longitudinal axis of the elongate opening of the fixing portion of the same angular orientation along both longitudinal sides of the opening. In this case, optimal loads of the fastening means while minimizing the space requirement of the respective fastening portion of the stop element can be achieved in that the respective wedge surface adjoins the elongate opening of the fastening portion.
Die erfindungsgemäß jeweils an dem Befestigungsabschnitt des Anschlagelements ausgebildete Keilfläche ist selbstverständlich jeweils so ausgerichtet, dass die erfindungsgemäß vorgesehene Verkeilung des Anschlagelements an dem jeweiligen Befestigungsmittel erreicht wird. D.h., die jeweils wirksame Keilfläche ist so ausgerichtet, dass in Folge einer der durch die jeweiligen Haltekräfte ausgelösten eventuellen Bewegung des Anschlagelements das Befestigungsmittel in Richtung der von ihm ausgeübten Spannkraft belastet und nicht entlastet wird.The wedge surface formed on the attachment portion of the stop element according to the invention is, of course, in each case oriented such that the wedging of the stop element to the respective attachment means provided according to the invention is achieved. That is, the respective effective wedge surface is aligned so that as a result of one of the triggered by the respective holding forces eventual movement of the stop element, the fastening means is loaded in the direction of the clamping force exerted by it and not relieved.
Um die Montage eines erfindungsgemäßen Anschlagelements im Hinblick auf die derart ordnungsgemäße Ausrichtung der Keilfläche zu vereinfachen, sieht eine weitere Ausgestaltung der Erfindung vor, dass mindestens ein Paar von Keilflächen vorhanden ist, von denen die Ebene der einen Keilfläche gegenläufig zur Ebene der anderen Keilfläche unter einem spitzen Winkel bezogen auf die Längsachse der Öffnung ausgerichtet ist. Auf diese Weise steht unabhängig von der jeweiligen Anordnung des Anschlagelements an dem Befestigungsabschnitt immer eine Keilfläche zur Verfügung, über die unter Wirkung der jeweils längs der Öffnung des Befestigungsschnitts ausgerichteten Anteils der Hebekräfte das Anschlagelement gegen das jeweilige Befestigungsmittel verspannt wird. Im Hinblick auf die gleichmäßige Belastung des Befestigungsabschnitts kann es sich auch in diesem Zusammenhang als zweckmäßig erweisen, dass sich jeweils ein Paar von gegenläufig ausgerichteten Keilflächen entlang jeder der Längsseiten der Öffnung erstreckt. Um dabei unabhängig von der jeweiligen Ausrichtung der Keilflächen jedes Keilflächenpaares dieselbe Keilwirkung zu erreichen, ist es günstig, wenn die Ebenen der Keilflächen des jeweiligen Paares von Keilflächen sich unter einem betragsmäßig gleichen Winkel die Längsachse der Öffnung schneiden.In order to simplify the assembly of a stop element according to the invention with respect to the proper orientation of the wedge surface, a further embodiment of the invention provides that at least one pair of wedge surfaces is present, of which the plane of the one wedge surface opposite to the plane of the other wedge surface under a acute angle relative to the longitudinal axis of the opening is aligned. In this way, regardless of the respective arrangement of the stop element at the attachment portion always a wedge surface is available over which under the action of each aligned along the opening of the attachment section portion of the lifting forces the stop element is clamped against the respective fastening means. In view of the uniform loading of the fastening portion, it may also be useful in this context for a pair of oppositely oriented wedge surfaces to extend along each of the longitudinal sides of the opening. In order to achieve the same wedge effect regardless of the respective orientation of the wedge surfaces of each wedge surface pair, it is advantageous if the planes of the wedge surfaces of the respective pair of wedge surfaces intersect the longitudinal axis of the opening at a same angle.
Sind zwei Paare von jeweils gegenläufigen Keilflächen pro Befestigungsabschnitt vorgesehen, so kann die gleichmäßige Belastung des jeweiligen Befestigungsmittels auch dadurch unterstützt werden, dass die dem jeweiligen Längsrand der Öffnung des Befestigungsabschnitts zugeordneten Keilflächen in dieselbe Richtung geneigt verlaufen. In diesem Fall sind die an dem jeweiligen Befestigungsabschnitt vorhandenen, in dieselbe Richtung geneigten Keilflächen jeweils spiegelsymmetrisch zur Längsachse der Öffnung des Befestigungsabschnitts angeordnet.If two pairs of opposing wedge surfaces per attachment section are provided, the uniform loading of the respective attachment means can also be assisted by the wedge surfaces associated with the respective longitudinal edge of the opening of the attachment section being inclined in the same direction. In this case, those at the respective Fixing portion existing, inclined in the same direction wedge surfaces each arranged mirror-symmetrically to the longitudinal axis of the opening of the attachment portion.
Im Fall, dass bei einer erfindungsgemäßen Kombination aus Anschlagelement und Befestigungsmittel das Befestigungsmittel ein Adapterstück aufweist und an dem Befestigungsabschnitt des Anschlagelements zwei Paare von gegenläufigen Keilflächen vorhanden sind, kann die Abstützung des Spannmittels auf den Keilflächen des Befestigungsabschnitts dadurch besonders gut gesichert werden, dass das Adapterstück mindestens zwei Vorsprünge aufweist, an denen jeweils eine Keilfläche ausgebildet ist, die jeweils einer der in dieselbe Richtung geneigten Keilflächen des Befestigungsabschnitts zugeordnet ist. In diesem Fall ist also das Adapterstück immer auf zwei gleich geneigten Keilflächen des Befestigungsabschnitts abgestützt. Sollen die beiden jeweils in die andere Richtung geneigten Keilflächen genutzt werden, so kann dazu ein entsprechend angepasstes zweites Adapterstück genutzt werden.In the case that in a combination of stopper element and fastening means according to the invention, the fastening means comprises an adapter piece and two pairs of opposing wedge surfaces are present on the attachment portion of the stop element, the support of the clamping means on the wedge surfaces of the attachment portion can be particularly well secured that the adapter piece Has at least two projections, on each of which a wedge surface is formed, which is associated with each one of the inclined in the same direction wedge surfaces of the mounting portion. In this case, therefore, the adapter piece is always supported on two equally inclined wedge surfaces of the mounting portion. If the two wedge surfaces inclined in the other direction are to be used, a correspondingly adapted second adapter piece can be used for this purpose.
Alternativ kann das Adapterstück auch so ausgebildet sein, dass es durch Umsetzen um seine Längsachse auf den in die eine oder andere Richtung gerichteten Keilflächen abgestützt ist. Im Fall, dass die in dieselbe Richtung gerichteten Keilflächen des Befestigungsabschnitts spiegelsymmetrisch zur Längsachse seiner Öffnung angeordnet sind, kann dazu das Adapterstück ein Paar von Keilflächen aufweisen, die entsprechend den entfernt von den Längsseiten der Öffnung des zugeordneten Befestigungsabschnitts angeordnet sind, und ein Paar von zwischen dem ersten Paar angeordneten Keilflächen, die den benachbart zu den Längsrändern der Öffnung des Befestigungsabschnitts und quer zu den Keilflächen des ersten Paares von Keilflächen angeordnet sind. Die freie Beweglichkeit des Adapterstücks kann dabei dadurch gesichert werden, dass die Länge des zweiten Paares von Keilflächen so bemessen ist, dass die Keilflächen dieses Paares bei einer Ausrichtung quer zur Längsachse der Öffnung des Befestigungsabschnitts mit Spiel durch die Öffnung längs deren Längsachse bewegbar sind. Auf diese Weise kann mit einem Adapterstück oder einem entsprechend ausgebildeten einstückigen Befestigungsmittel die Anpassung an die jeweilige Befestigungssituation ohne Wechsel des Befestigungsmittels durchgeführt werden. Dabei sind auf das Spannelement des Befestigungsmittels wirkende Querkräfte weitestgehend minimiert.Alternatively, the adapter piece can also be designed so that it is supported by moving about its longitudinal axis on the directed in one or the other direction wedge surfaces. In the case that the wedge surfaces of the attachment portion directed in the same direction are arranged mirror-symmetrically with respect to the longitudinal axis of its opening, the adapter piece may for this purpose have a pair of wedge surfaces corresponding to those located away from the longitudinal sides of the opening of the associated attachment portion and a pair of between the first pair of spaced wedge surfaces located adjacent to the longitudinal edges of the opening of the attachment portion and across the wedge surfaces of the first pair of wedge surfaces. The free mobility of the adapter piece can be secured by the fact that the length of the second pair of wedge surfaces is dimensioned so that the wedge surfaces of this pair are movable with an orientation transverse to the longitudinal axis of the opening of the attachment portion with play through the opening along its longitudinal axis. In this way, the adaptation to the respective mounting situation without changing the fastener can be performed with an adapter piece or a correspondingly formed one-piece fastening means. In this case acting on the clamping element of the fastening means transverse forces are minimized as far as possible.
Alternativ zu einer spiegelsymmetrischen Anordnung können an dem Anschlagelement die Keilflächen der Keilflächenpaare des Befestigungsabschnitts auch so angeordnet werden, dass die dem jeweiligen Längsrand zugeordneten Keilflächen in entgegengesetzter Richtung geneigt verlaufen. In Bezug auf die erfindungsgemäße Kombination hat diese Ausgestaltung den Vorteil, dass durch einfaches Umsetzen um 180 ° um die Längsachse des Spannmittels der Adapter an die jeweilige Montagesituation angepasst werden kann, wenn in den Adapter eine den erforderlichen Versatz zulassende Langöffnung eingeformt bzw. bei einer einstückigen Ausbildung des Befestigungsmittels der mit den Keilflächen versehene Absatz bezogen auf die Längsachse des Spannmittels ausreichend außermittig angeordnet ist.As an alternative to a mirror-symmetrical arrangement, the wedge surfaces of the wedge surface pairs of the fastening section can also be arranged on the stop element in such a way that the wedge surfaces assigned to the respective longitudinal edge are inclined in the opposite direction. With regard to the combination according to the invention, this embodiment has the advantage that the adapter can be adapted to the respective mounting situation by simply translating 180 ° about the longitudinal axis of the clamping means if a long opening permitting the required offset is formed in the adapter or in one piece Formation of the fastener provided with the wedge-shaped paragraph based on the longitudinal axis of the clamping means is arranged sufficiently off-center.
Eine besonders einfache Gestaltung bei gleichzeitig besonders sicherer Funktion ergibt sich, wenn die Öffnung des Befestigungsabschnitts als Langloch mit parallel zueinander verlaufenden Längsseiten ausgebildet ist. Bei dieser Ausgestaltung können auch die Keilflächen in Draufsicht gesehen einen linearen Verlauf besitzen, so dass das jeweilige Befestigungsmittel problemlos auf ihnen verschoben werden kann.A particularly simple design with a particularly reliable function is obtained when the opening of the fastening portion is formed as a slot with parallel longitudinal sides. In this embodiment, the wedge surfaces seen in plan view may have a linear course, so that the respective fastening means can be easily moved on them.

Genauso könnten die Befestigungsabschnitte 3,4, jedoch auch in Draufsicht gesehen winklig zum Anschlagabschnitt 2 ausgerichtet sein, so dass sich ihre Längsachsen L3,L4 unter einem spitzen Winkel schneiden. Eine solche Anordnung kann beispielsweise dann zweckmäßig sein, wenn das jeweilige Anschlagelement an einem kreisrunden Flansch mit vergleichbar kleinem Durchmesser befestigt werden soll.

Das Untermaß ist in diesem Fall so bemessen, dass die Adapter 24,25 bei quer zur Längsachse L3,L4 ausgerichteter Breite B leicht durch den seitlich von den äußeren Keilflächen 14b,15b bzw. 16b,17b begrenzten Raum bewegt werden können.Correspondingly, the width B of the
