Description
KrangerüstCrane frame
Die Erfindung bezieht sich auf Krangerüste, deren Trägerteile durch Klemmvorrichtungen miteinander verbunden sind.The invention relates to crane frames, the support parts of which by clamping devices are connected to each other.
Die Unterteilung des Gerüstes eines Hebezeuges in mehrere auswechselbare Teile ist bekanntlich erforderlich einerseits, um die Hubhöhe des Hebezeuges beliebig verändern zu können, andererseits bei Wechsel des Standortes des Hebezeuges einzelne Teile ypn geringer Größe und geringem Gewicht zur Erleichterung des Transportes zu erhalten. Bei Turmkranen geschieht die Verbindung der einzelnen Teile eines Turmes bisher dadurch, daß an den Stoßenden der Turmteile Laschen angebracht und dieselben mit Bohrungen ausgerüstet sind, so daß nach Durchstecken von Schrauben durch Anziehen der Schraubenmuttern die Verbindung hergestellt wird. Diese Befestigungsweise hat aber den Nachteil, daß der Schraubenschaft bei einer Ausführungsart der Verbindung auf Abscherung, bei der anderen Verbindungsart auf Zug beansprucht ist. Beide Beanspruchungen sind ungünstig. In diesen Bohrungen tritt im Laufe der Zeit infolge der Beanspruchungen des Turmkranes durch das Anheben der Last und das Verschwenken des Kranes ein gewisses Spiel auf, was aber nicht dadurch beseitigt werden kann, daß die Bohrungen größer ausgeführt werden und stärkere Schrauben zur Verbindung der Turmteile genommen werden, denn die geforderte Auswechselbarkeit der einzelnen zum Teil noch nicht benutzten Turmteile erfordert gleich große Bohrungen und gleiche Schraubendurchmesser. Infolgedessen entstehen beim Anheben einer Last und beim Absetzen einer Last im Turmgerüst ruck- und stoßartige Wirkungen, welche die Lebensdauer des Turmkranes herabsetzen. Außerdem erfordert die Montage des Turmes bisher einen großen Aufwand an Zeit.The subdivision of the frame of a hoist in several interchangeable parts is known to be necessary on the one hand to the To be able to change the lifting height of the hoist as desired, on the other hand when changing the Location of the hoist for individual parts of small size and light weight To get easier transportation. The connection is made with tower cranes of the individual parts of a tower so far that at the butt ends of the tower parts Lugs attached and the same equipped with holes, so that after pushing through screws by tightening the screw nuts make the connection. This method of attachment has but the disadvantage that the screw shank in one embodiment of the connection Shearing, in which the other type of connection is subject to tension. Both stresses are unfavorable. In these holes occurs over time as a result of the stresses of the tower crane due to the lifting of the load and the pivoting of the crane a certain amount of play, but what not this can be eliminated by making the bores larger and stronger Screws to connect the tower parts are taken, because the required interchangeability the individual tower parts, some of which have not yet been used, require holes of the same size and the same screw diameter. As a result, jerks and jolts occur when a load is lifted and when a load is set down in the tower structure Effects that reduce the service life of the tower crane. Also requires the Assembly of the tower has so far taken a great deal of time.
Hier verbessert nun die Erfindung dadurch, daß auf den Stoßlaschen Nasen angebracht sind, über welche geschlossene Klammern übergreifen, die sich einerseits selbst und andererseits mittels Druckschrauben an den Nasen abstützen. Zum Zwecke einer sicheren Abstützung sind die Nasen auf ihrer dem Stoß abgekehrten Seite mit Ausnehmungen versehen.Here the invention is now improved in that noses are attached to the butt tabs are over which closed brackets overlap, on the one hand themselves and on the other hand, support it on the noses by means of pressure screws. For the purpose of safe For support, the noses are provided with recesses on their side facing away from the impact.
In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt. In the drawing, the subject matter of the invention is shown in one embodiment.
Fig. ι zeigt einen Turmkran gewöhnlicher Bauart.Fig. Ι shows a tower crane of conventional design.
Fig. 2 und 3 zeigen in größerem Maßstabe Verbindungsstellen der Turmteile mit der neuen Klammer.Fig. 2 and 3 show on a larger scale connection points of the tower parts with the new bracket.
Der Turm des in Fig. 1 dargestellten Kranes ist aus mehreren gleich großen und gleichartigen Teilen 1, 2 usw. zusammengesetzt. Gemäß Fig. 2 und 3 sind an den Stoßen der Turmteile 1 und 2 Laschen a und b aufgenietet, welche Klauen c und d tragen. Die Klauen können entweder genau auf den Ecken angebracht sein. (Fig. 2), oder sie können auf einer Seitenbahn der winkeligen Laschen α und b befestigt sein. Über die Klauen greift eine Klammer e über, welche ringsum geschlossen ist und deren eine Seite von einer Schraube/ durchsetzt wird, wobei der betreffende Klammerteil g die Mutter für das Schraubengewinde bildet. Damit die Klammer nicht von den Klauen herabrutschen kann, sind in den Klauen Ausnehmungen h vorgesehen, in welche sich eine Seite der Klammer bzw. das freie Ende der Druckschraube/ einlegt.The tower of the crane shown in FIG. 1 is composed of several parts 1, 2, etc. of the same size and of the same type. According to FIGS. 2 and 3, tabs a and b are riveted to the joints of the tower parts 1 and 2, which claws c and d carry. The claws can either be fitted exactly on the corners. (Fig. 2), or they can be attached to a side panel of the angled tabs α and b. A clamp e engages over the claws, which is closed all around and one side of which is penetrated by a screw /, the relevant clamp part g forming the nut for the screw thread. So that the clamp cannot slip off the claws, recesses h are provided in the claws, into which one side of the clamp or the free end of the pressure screw / is inserted.
Das Überhängen der Klammern über die Klauen geht verhältnismäßig einfach und leicht vor sich; ebenso bequem lassen sich die Schrauben / anziehen, wobei die neue Verbindung für auswechselbare Teile eines Hebezeuges den Vorteil besitzt, daß die Schraube nur auf Druck beansprucht wird und der lösbaren Verbindung eine den in Frage kommenden Lasten entsprechende Vorspannung gegeben werden kann.The overhanging of the clamps over the claws is relatively easy and easily in front of you; The screws / can be tightened just as easily, with the new connection for replaceable parts of a hoist has the advantage that the screw is only subjected to pressure and the releasable one Connection can be given a preload corresponding to the loads in question.
