Die Erfindung betrifft ein Lastaufnahmemittel, insbesondere Unterflasche eines Hebezeuges, mit einem einen Schaft aufweisenden Haken, der eine umlaufende Nut aufweist, in die ein ringförmiges Halteelement eingreift, das sich an einer Tragfläche eines Aufhängeelements des Lastaufnahmemittels abstützt, wobei das ringförmige Haltelement die Form einer Hülse hat, die sich ausgehend von dem Schaft in Richtung der Tragfläche erweitert.The invention relates to a load-receiving means, in particular lower block of a hoist, having a shank having a hook which has a circumferential groove, in which an annular retaining element engages, which is supported on a support surface of a suspension element of the load-receiving means, wherein the annular retaining element in the form of a sleeve has, which extends from the shaft towards the wing.
Aus dem Patent

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein sicheres Lastaufnahmemittel, insbesondere eine Unterflasche eines Hebezeuges, zu schaffen.The present invention is based on the object to provide a secure load-carrying means, in particular a lower bottle of a hoist.
Diese Aufgabe wird durch ein Lastaufnahmemittel, insbesondere eine Unterflasche eines Hebezeuges, mit den Merkmalen des Anspruchs 1 gelöst. Die Unteransprüche 2 bis 11 beschreiben vorteilhafte Ausgestaltungen des Lastaufnahmemittels.This object is achieved by a load-receiving means, in particular a lower bottle of a hoist, with the features of
Erfindungsgemäß wird bei einem Lastaufnahmemittel, insbesondere Unterflasche eines Hebezeuges, mit einem einen Schaft aufweisenden Haken, der eine umlaufende Nut aufweist, in die ein ringförmiges Halteelement eingreift, das sich an einer Tragfläche eines Aufhängeelements des Lastaufnahmemittels abstützt, wobei das ringförmige Haltelement die Form einer Hülse hat, die sich ausgehend von dem Schaft in Richtung der Tragfläche erweitert, eine sichere Ausgestaltung dadurch erreicht, dass das ringförmige Haltelement in Form einer konusförmigen Hülse nach Art eines Kegelstumpfs ausgebildet ist und eine Außen-Mantelfläche, durch die Hülsenform eine Innen-Mantelfläche, eine obere ringförmige Deckfläche und eine untere ringförmige Grundfläche hat. Die konusförmige Gestalt ermöglicht eine besonders günstige Einleitung der aus dem Lastaufnahmemittel und der daran hängenden Last resultierenden Kräfte in den Tragring. Durch diese Ausgestaltung werden die Kontaktflächen zwischen dem Halteelement, dem Schaft und der Nut vergrößert, so dass auch die entsprechenden Flächenpressungen besser beherrschbar werden. Die gelenkige Lagerung des länglichen konusförmigen Halteelements unten auf dem Tragring und oben an der Nut führt zu einer gleichmäßigeren Verteilung der Pressungen und Spannungen. Hierdurch wird das Halteelement auch unanfälliger gegen Fertigungstoleranzen. Der Kraftfluss verläuft hierbei in dem Halteelement gleichmäßig zwischen der Nut und der Tragfläche. Vorteilhafter Weise treten gegenüber einem kreisförmigen Halteelement keine Scherspannungen im Halteelement auf. Zusätzlich ist von Vorteil, dass ein Montagefehler in Form eines Weglassens des ringförmigen Halteelements sofort erkannt werden kann, da der Schaft des Hakens aus dem Aufhängeelement heraus gleitet. Dieser Montagefehler kann somit auch nach Fertigmontage des Lastaufnahmemittels erkannt werden, wenn das ringförmige Halteelement von außen durch andere Bauteile verdeckt nicht mehr sichtbar wäre.According to the invention, in a load-receiving means, in particular lower block of a hoist, having a hook having a shank, which engages in an annular groove, which is supported on a support surface of a suspension element of the lifting device, wherein the annular retaining element in the form of a sleeve has, which widens starting from the shaft in the direction of the supporting surface, a secure configuration achieved in that the annular holding element is designed in the form of a cone-shaped sleeve in the manner of a truncated cone and an outer circumferential surface, through the sleeve shape an inner circumferential surface, a upper annular top surface and a lower annular base has. The conical shape allows for a particularly favorable introduction of the forces resulting from the load-carrying means and the load hanging thereon in the support ring. As a result of this embodiment, the contact surfaces between the retaining element, the shaft and the groove are enlarged, so that the corresponding surface pressures can also be better controlled. The articulated mounting of the elongated cone-shaped holding element at the bottom of the support ring and at the top of the groove leads to a more uniform distribution of the compressions and stresses. As a result, the holding element is also less susceptible to manufacturing tolerances. The power flow in this case runs evenly between the groove and the support surface in the retaining element. Advantageously, no shear stresses occur in the holding element in relation to a circular holding element. In addition, it is advantageous that an assembly error in the form of omitting the annular retaining element immediately can be recognized, since the shank of the hook slides out of the suspension. This assembly error can thus be detected even after final assembly of the lifting device, if the annular retaining element hidden from the outside by other components would no longer be visible.
Besonders vorteilhaft ist vorgesehen, dass bei vertikal ausgerichteter Schaftachse des Schaftes gesehen das ringförmige Haltelement oben eine Stützfläche, die dem Schaft zugewandt ist, und unten eine Standfläche, die der Tragfläche zugewandt ist, aufweist, die Stützfläche mit dem Schaft in Kontakt steht und die Standfläche mit der Tragfläche in Kontakt steht.Particularly advantageous is provided that when viewed vertically aligned shaft axis of the shaft, the annular retaining element above a support surface which faces the shaft, and below a footing, which faces the support surface, the support surface is in contact with the shaft and the footprint in contact with the wing.
Hohe Kerbspannungen werden dadurch vermieden, dass die Stützfläche und die Standfläche jeweils konvex gekrümmt, insbesondere kreisbogenförmig, sind. Außerdem wird hierdurch eine Selbstzentrierung zwischen Halteelement, Schaft und Tragring erreicht.High notch stresses are avoided in that the support surface and the footprint are each convexly curved, in particular circular arc-shaped. In addition, a self-centering between retaining element, shaft and support ring is thereby achieved.
Ein besonders optimale Durchleitung der aus dem Lastaufnahmemittel und der daran hängenden Last resultierenden Kräfte durch das Halteelement wird dadurch erreicht, dass die obere ringförmige Deckfläche des Haltelementes in Form der Stützfläche und die untere ringförmige Deckfläche des Halteelementes in Form der Standfläche ausgebildet sindA particularly optimal passage of the forces resulting from the load receiving means and the load resulting therefrom by the holding element is achieved in that the upper annular top surface of the holding element in the form of the support surface and the lower annular top surface of the holding element in the form of the base are formed
Bevorzugt ist vorgesehen, dass die Innen-Mantelfläche und die Außen-Mantelfläche parallel zueinander verlaufen.It is preferably provided that the inner circumferential surface and the outer circumferential surface extend parallel to one another.
In konstruktiver Hinsicht ist vorteilhaft, dass sich an die Krümmungsfläche der umlaufenden Nut eine lineare Anlagefläche anschließt, die sich in Richtung der Tragfläche erweitert, und das ringförmige Haltelement mit seiner Innen-Mantelfläche an der Anlagefläche der umlaufenden Nut anliegt. Hierdurch wird das Haltelement zusätzlich seitlich von dem Schaft gestützt.In terms of design, it is advantageous that adjoins the curvature surface of the circumferential groove, a linear contact surface which widens in the direction of the support surface, and abuts the annular retaining element with its inner circumferential surface on the contact surface of the circumferential groove. As a result, the holding element is additionally supported laterally by the shaft.
Die Einleitung der aus dem Lastaufnahmemittel und der daran hängenden Last resultierenden Kräfte in den Tragring wird weiter dadurch optimiert, dass die Tragfläche und die Standfläche sich in der Anlage ergänzende Konturen aufweisen, da hierdurch ein bauteilschonender flächiger Kontakt zwischen Halteelement und Tragring erreicht wird. Entsprechendes gilt für die Stützfläche und die Krümmungsfläche, die ebenfalls sich in der Anlage ergänzende Konturen aufweisen. Besonders vorteilhaft ist vorgesehen, dass die umlaufende Nut eine Krümmungsfläche aufweist, die mit der Stützfläche des ringförmigen Haltelements in Kontakt steht.The initiation of the forces resulting from the load-carrying means and the resulting load in the support ring is further optimized by the fact that the support surface and the footprint have complementary contours in the system, as a component gentle flat contact between the holding element and Supporting ring is reached. The same applies to the support surface and the curvature surface, which also have complementary contours in the system. It is particularly advantageously provided that the circumferential groove has a curved surface, which is in contact with the support surface of the annular retaining element.
In einer alternativen Ausgestaltung ist vorgesehen, dass die Tragfläche innen und oben auf einem Tragring angeordnet ist und der Tragring über ein Axialkugellager auf dem Aufhängelement abgestützt ist. Die Anordnung der Tragfläche an dieser Stelle begünstigt die Einleitung der aus dem Lastaufnahmemittel und der daran hängenden Last resultierenden Kräfte in den Tragring. Die Verwendung eines Axialkugellager ermöglicht zusätzlich eine Drehbarkeit des Hakens um seine Schaftachse.In an alternative embodiment it is provided that the support surface is arranged inside and on top of a support ring and the support ring is supported on the suspension element via an axial ball bearing. The arrangement of the support surface at this point favors the initiation of the forces resulting from the load-carrying means and the load attached thereto in the support ring. The use of an axial ball bearing additionally allows a rotation of the hook about its shaft axis.
Besonders vorteilhaft ist vorgesehen, dass das ringförmige Haltelement in mindestens zwei Segmente geteilt ist. Hierdurch wird die Montage des Hakens an das Aufhängeelement erleichtert, da die Segmente leichter in die Nut des Schaftes seitlich einsetzbar sind und sich dann in der Nut ruhend zu einem vollständigen vollringförmigen Haltelement ergänzen.It is particularly advantageously provided that the annular holding element is divided into at least two segments. As a result, the assembly of the hook is facilitated to the suspension, since the segments are easier to insert laterally into the groove of the shaft and then complemented in the groove resting to a complete full-ring-shaped holding element.

Für den Fall, dass das Lastaufnahmemittel 1 einsträngig ausgebildet ist, d. h. nur an einem Seil oder einer Kette aufgehängt ist, kommt üblicher Weise keine Traverse 3 zum Einsatz. Dann wird der Haken 2 direkt einem gehäuseartig ausgebildeten Aufhängeelement mit einer entsprechenden Durchgangsöffnung 4 befestigt. Aus Montagegründen kann dieses Aufhängeelement geteilt sein. Das Lastaufnahmemittel 1 kann auch eine Lastöse sein.In the event that the load-receiving means 1 is formed single-stranded, d. H. is suspended only on a rope or a chain, usually no

Auch kann es bei dem Betrieb des Lastaufnahmemittels 1 dazu kommen, dass der Haken 2 auf einem Gegenstand oder einer Last aufsetzt und der Schaft 2a in die Durchgangsöffnung 4 soweit hinein bewegt wird, bis ein konusförmiger Absatz 12, der den Übergang zwischen dem Hakenteil 2b und dem Schaft 2a mit einem geringeren Durchmesser als das Hakenteil 2b bildet, zur Anlage an der Traverse 3 oder ein Teil des nicht dargestellten Aufhängeelements kommt. Hierdurch kann sich auch das Halteelement 6 aus dem Tragring 7 hinausbewegen, was bei einem in Segmente 6e, 6f geteilten Halteelement 6 dazu führen könnte, dass das Halteelement 6 die Nut 5 in seitlicher Richtung verlässt. Um dies zu verhindern, ist auf dem Tragring 7 ein Verriegelungsring 9 angeordnet, dessen innere lineare Umfangsfläche 9a, die parallel zur Schaftachse S verläuft, mit dem oberen Ende der Tragfläche 7a fluchtet beziehungsweise dessen Durchmesser der inneren linearen Umfangsfläche 8a dem maximalen Außendurchmesser des Halteelements 6 entspricht. Ein geringes, die Montage erleichterndes Spiel zwischen dem Tragring 7 und dem Halteelement 6 kann vorhanden sein. Damit der Verriegelungsring 9 den Kontakt zu dem Tragring 7 in axialer Richtung beibehält, sind der Tragring 7, der Verriegelungsring 9 und das Axiallager 8 konzentrisch von der Innenwand 10a des Aufnahmeraums 10 der Traverse 3 umgeben. In der Innenwand 10a ist eine Innennut 10c angeordnet, in die eine handelsüblicher Sicherungsring 11 eingesetzt ist. In Bezug auf eine vertikal ausgerichtete Schaftachse S ist die Höhe der Innennut 10c beziehungsweise der Abstand zu dem Tragring 7 so gewählt, dass der Sicherungsring 11 ein Abheben des Verriegelungsrings 9 von dem Tragring 7 verhindert.It can also happen in the operation of the load receiving means 1 that the

Das Haltelement 6 hat dann einen parallelogrammförmigen Querschnitt, wobei die obere innere Ecke durch die Stützfläche 6c und die untere äußere Ecke durch die Standfläche 6d abgerundet sind.In principle, it is also possible to form the upper cover surface from a horizontal linear upper section and a curved support surface 6c adjoining thereto, and the lower cover surface from a horizontal linear lower section and a curved standing surface 6di adjoining thereto.
