Description
Kletterkran Für die Errichtung von hohen Gebäuden sind bereits Turmdrehkrane bekannt, deren Ausleger und Hubwerk enthaltender Mastteil an einem in Schüssen aufstockbaren Standmast klettern kann und sowohl zum Hochrüsten der Schüsse wie auch zum anschließenden Klettern an einem über Flaschenzugrollen laufenden Kletterseil den Lasthaken benutzt.Climbing crane Tower cranes are already used for erecting tall buildings known, the boom and hoist containing mast part on a topped up in shots Stand mast can climb and both for upgrading the shots as well as for subsequent Climbing on a climbing rope running over pulleys, use the load hook.
Bei einem solchen bekannten Kletterkran ist der Flaschenzug aus dem Kletterseil seitlich am montierten Standmast anzubringen, um einen neuen Klettervorgang zu ermöglichen. Nach jedem Klettern müssen aber die Rollenböcke und damit auch das Kletterseil vom Standmast entfernt werden, um Platz zu schaffen für das Aufsetzen eines neuen Mastschusses mit dem Lasthaken am Ausleger.In such a known climbing crane, the pulley is from the Attach the climbing rope to the side of the mounted mast to start a new climbing process to enable. After every climb, however, the roller blocks and thus also the Climbing rope must be removed from the mast to make room for it to be put on a new mast section with the load hook on the boom.
Die für jeden einzelnen Klettervorgang zu wiederholende Montage und Demontage des Flaschenzuges aus dem Kletterseil ist nicht nur umständlich, sondern auch gefährlich, weil eben der erwähnte Flaschenzug aus dem Kletterseil außen am jeweils obersten Mastschuß angebracht bzw. abgenommen werden muß.The assembly to be repeated for each individual climbing process and Dismantling the pulley from the climbing rope is not only cumbersome, but also dangerous, because the aforementioned pulley system from the climbing rope on the outside of the topmost mast section must be attached or removed.
Dieser Nachteil wird erfindungsgemäß bei einem Kran der eingangs genannten Art dadurch vermieden, daß der durch das Kletterseil gebildete Flaschenzug im seitlich kletternden Mastteil dauernd eingeschlossen und mit nur einem Tram herausgeführt ist, dessen Ende zum Klettern an dem jeweils obersten Mastschuß bzw. einem Ablegehaken oben am Klettermast einhängbar ausgeführt ist.According to the invention, this disadvantage becomes the one mentioned at the beginning in a crane Art avoided in that the pulley system formed by the climbing rope in the side The climbing mast part is permanently enclosed and brought out with only one tram is, the end of which for climbing on the topmost mast section or a discarding hook is designed to be suspended at the top of the climbing mast.
Durch den Kunstgriff der Unterbringung des Flaschenzuges aus - dem Kletterseil innerhalb des kletternden Mastteiles wird also in Verbindung mit dem erfindungsgemäßen Ablegehaken jeweils am Mastschuß und am Klettermast die Monteurarbeit zur Vorbereitung des Kletterns wie auch des Hochrüstens eines neuen Mastschusses jeweils auf das Umhängen des abtriebsseitigen Kletterseilendes vom Ablegehaken am Mastschuß auf denjenigen am kletternden Mastteil oder umgekehrt reduziert.With the trick of accommodating the pulley system from the Climbing rope within the climbing mast part is therefore used in conjunction with the Discarding hooks according to the invention in each case on the mast section and on the climbing mast, the assembly work to prepare for climbing as well as upgrading a new mast section in each case on the hanging of the climbing rope end on the output side from the hook on the Mast section reduced to that on the climbing mast part or vice versa.
Zur weiteren Erleichterung des Klettervorganges kann das feste Hubseilende beim Klettern über eine Umlenkrolle geführt und an die mit dem Lasthaken bewegliche Seilflasche des aus dem Hubseil gebildeten Flaschenzugs anschließbar ausgeführt werden. Dadurch wird nämlich die Tragkraft des Lasthakens vergrößert, so daß entsprechend längere und schwerere Mastschüsse hoch gerüstet werden können und zur Erreichung der gleichen Förderhöhe eine geringere Anzahl von Klettervorgängen notwendig ist.To make the climbing process even easier, the fixed end of the hoist rope guided over a pulley when climbing and attached to the movable one with the load hook Rope block of the pulley system formed from the hoist rope designed to be connectable will. This namely increases the load capacity of the load hook, so that accordingly longer and heavier mast sections can be upgraded and used to achieve the same head a smaller number of climbing operations is necessary.
Ein entsprechender Vorteil kann in Weiterbildung der Erfindung auch dadurch erreicht werden, daß das Kletterseil im kletternden Mastteil zwei hintereinandergeschaltete Flaschenzüge bildet, deren Tot ende oben im kletternden Mastteil fest ist, vorzugsweise in einem mit dem Ablegehaken einstückigen Auge.A corresponding advantage can also be achieved in a further development of the invention can be achieved in that the climbing rope in the climbing mast part two connected in series Forms pulleys, the dead ends of which is fixed up in the climbing mast part, preferably in an eye integral with the discarding hook.
Eine weitere Vereinfachung der Montagearbeit kann erfindungsgemäß erzielt werden durch die Gestaltung der Stoßverbindung zwischen den Mastschüssen als in den Ablegehaken für das abtriebsseitige Kletterseilende übergehende Bolzenverbindung. Der Monteur kann ohne Werkzeug und an der gleichen Stelle, also mit der gleichen Hand, das Ablegen des Kletterseilendes und das Einstecken des Verbindungsbolzens nach dem Hochrüsten eines Mastschusses vornehmen, so daß er sich mit der anderen Hand dabei festhalten kann.A further simplification of the assembly work can according to the invention can be achieved by designing the butt joint between the mast sections as a bolt connection passing over into the deposit hook for the climbing rope end on the output side. The fitter can work without tools and in the same place, i.e. with the same Hand, putting down the climbing rope end and inserting the connecting bolt after upgrading one mast section so that it is aligned with the other Hand can hold on to it.
Gleichfalls der einfacheren und sicheren Montage dient in Weiterbildung der Erfindung die Anwendung einer Arbeitsplattform in den Mastschüssen.Simpler and safer assembly is also used in further training the invention the use of a work platform in the mast sections.
Ebenfalls zur Erleichterung des Klettervorganges kann in an sich bekannter Weise der Angriffspunkt des Flaschenzuges etwa im Schwerpunkt des zu hebenden Mastteils angebracht sein, also nicht in der Achse des kletternden Mastteiles, sondern näher an demjenigen Profilende, welches dem Lastausleger und dem festen Mast zugekehrt ist. Dadurch wird trotz des erfindungsgemäß angewandten unsymmetrisch angreifenden einzigen Kletterseiltrums eine Behinderung des Klettervorganges durch Kippbeanspruchung der Führung des kletternden Mastteiles auf dem festen Mast vermieden. Beim einleitend erwähnten vorbekannten Kletterkran ist das nicht der Fall, trotz der dort aufwendigeren Kletterseilführung.Also to facilitate the climbing process can be known per se Way, the point of application of the pulley system approximately in the center of gravity of the mast part to be lifted be attached, so not in the axis of the climbing mast part, but closer at the end of the profile facing the load arm and the fixed mast is. As a result, despite the asymmetrical attack applied according to the invention single climbing rope stretches an obstruction of the climbing process due to tipping stress the leadership of the climbing mast part on the fixed mast avoided. At the introductory This is not the case, despite the more complex ones there Climbing rope guide.
Die Erfindung möge an Hand des in den Figuren schematisch dargestellten Ausführungsbeispiels weiter erläutert werden. Es zeigt F i g. 1 eine Gesamtansicht, F i g. 2 die konstruktive Zusammenfassung von Mastverriegelung und Ablegehaken in Seitenansicht, F i g. 3 einen Längsschnitt dazu, F i g. 4 eine mögliche Flaschenzuganordnung für das Verschieben des Klettermastes, deren Funktion in F i g. 5 für das Klettern am Standmast dargestellt ist, F i g. 6 das Hubwerk sowie dessen Seilführung. Während der Klettermast in seiner Länge immer gleichbleibt, kann der Standmast beliebig nach oben verlängert werden. Ab einer bestimmten Höhe muß derselbe jedoch aus Gründen der Standsicherheit mit dem bereits erstellten Gebäude verbunden werden.The invention may be shown schematically in the figures Embodiment are further explained. It shows F i g. 1 a general view, F i g. 2 the structural combination of mast locking and depositing hook in Side view, FIG. 3 shows a longitudinal section, FIG. 4 a possible pulley arrangement for moving the climbing mast, whose function is shown in F i g. 5 is shown for climbing on the standing mast, F i g. 6 the hoist and its Rope guide. While the length of the climbing mast always remains the same, the Stand mast can be extended upwards as required. From a certain height it must be the same but connected to the building that has already been built for reasons of stability will.
Hierbei liegt der Angriffspunkt des Kletterseiles annähernd in der Schwerlinie des nach oben gleitenden Teiles, so daß in der Gleitführung nur geringe horizontale Kräfte auftreten und Klemmungen beim Klettern vermieden werden.The point of application of the climbing rope is approximately in the Centroid of the upward sliding part, so that only slight in the sliding guide horizontal forces occur and jamming while climbing is avoided.
Bei dem in F i g. 1 dargestellten Kran, bestehend aus dem Unterwagen 1, dem Standmast 2, der Gleitführung 3, dem Ausleger, Gegenausleger und mechanische Teile tragenden Klettermast 4, wird mittels der Laufkatze 5 ein allseitig geschlossenes Mastzwischenstück 6 auf den Standmast gesetzt und mit diesem verbolzt. Durch ein am Standmast und jedem Verlängerungsstück über nicht dargestellte eingebaute Leitern zu erreichendes Arbeitspodest ist eine gefahrlose Durchführung aller für das Aufsetzen, Verbolzen und Gleiten des Klettermastes erforderlichen Arbeitsgänge möglich.In the case of the one shown in FIG. 1, consisting of the undercarriage 1, the standing mast 2, the sliding guide 3, the jib, counter-jib and mechanical parts-bearing climbing mast 4, an all-round closed mast adapter 6 is placed on the standing mast by means of the trolley 5 and bolted to it. A work platform that can be reached on the standing mast and each extension piece via built-in ladders (not shown) enables all operations required for setting up, bolting and sliding the climbing mast to be carried out safely.
Mittels der Laufkatze und des Lasthakens 5 (F i g. 1) wird das am Klettermast im Punkt G befindliche Ende des Kletterseiles 7 abgehoben und im Punkt A des neu aufgesetzten Stückes 6 eingelegt (F i g. 5).By means of the trolley and the load hook 5 (FIG. 1) the on Climbing mast located in point G, the end of the climbing rope 7 lifted and in point A of the newly placed piece 6 is inserted (FIG. 5).
Die Laufkatze 5 wird nun am Katzfahrwerk in den entsprechend ausgebildeten Klettermast eingefahren. Da normalerweise das Gewicht des zu hebenden Klettermastes mit seinen Teilen größer ist als die größte Nutzlast, muß für den Gleitvorgang die Hubkraft des Lasthakens vergrößert werden.The trolley 5 is now trained accordingly on the trolley Climbing mast retracted. Since usually the weight of the climbing mast to be lifted with its parts is greater than the largest payload, must for the sliding process The lifting force of the load hook can be increased.
Zu diesem Zweck wird das von der Hubtrommel kommende, flaschenzugartig über die Rollen 8 bis 14 (F i g. 6) geführte und beim Kranbetrieb in 15 (F i g. 5) endbefestigte Hubseil gelöst und in F mit dem Lasthaken verbunden.For this purpose, what comes from the lifting drum, is like a pulley block guided via rollers 8 to 14 (FIG. 6) and during crane operation in FIG. 15 (FIG. 5) loosened the hoist rope attached and connected to the load hook in F.
Reicht die Tragkraft je nach Krangröße für den Gleitvorgang noch nicht aus, ist es ohne weiteres möglich, zwischen Rolle 14 und Endbefestigung 15 weitere Flaschenzugrollen zu schalten, deren bewegliche Rollen dann im Punkt F mit dem Lasthaken verbunden werden.Depending on the size of the crane, does the load-bearing capacity not yet suffice for the sliding process off, it is easily possible between roller 14 and end attachment 15 more To switch pulley rollers, their movable rollers then in point F with the load hook get connected.
Nach Senken des Lasthakens wird derselbe in das Ende G des über die Rollen bei B geführten und in E endbefestigten separaten Kletterseiles eingehängt.After lowering the load hook the same is in the end G of the Roles at B guided and attached separate climbing rope attached at the end.
Das in A befestigte Kletterseil 7 ist über die Rollen D und die Ausgleichsrolle bei B wieder zum Endpunkt in A fiaschenzugartig geführt.The climbing rope 7 fastened in A is guided over the pulleys D and the compensating pulley at B back to the end point in A like a fiaschenzug.
Nach Lösen der Verriegelung zwischen Klettermast und Standmast gleitet der Klettermast durch motorisches Hochziehen des Lasthakens am neu aufgestellten Maststück 6 nach oben, bis er am oberen Ende von 6 wieder verriegelt werden kann.After releasing the lock it slides between the climbing mast and the standing mast the climbing mast by motorized lifting of the load hook on the newly erected one Mast section 6 upwards until it can be locked again at the upper end of 6.
Dann wird durch Senken des Lasthakens der Kletterflaschenzug entlastet, der Rollenbock B im Kletterturmende abgesetzt und der Lasthaken bei C gelöst und anschließend wieder gehoben, um das Hubseilende in F zulösen und im Punkt 15 wieder zu befestigen.Then the climbing pulley is relieved by lowering the load hook, the roller block B is set down in the end of the climbing tower and the load hook at C is loosened and then lifted again to release the end of the hoist rope in F and again in point 15 to fix.
Die Laufkatze wird aus dem Klettermast herausgefahren und mittels des Lasthakens das im Punkt A eingelegte Kletterseil wieder am Punkt G des Klettermastes abgelegt.The trolley is driven out of the climbing mast and by means of of the load hook the climbing rope inserted at point A again at point G of the climbing mast filed.
Hiernach kann auf die gleiche Weise das nächste Maststück auf den Standmast aufgesetzt werden.The next mast section can then be placed on the Stand mast to be put on.
