Abstract

The arrangement has a lifting cable passing from a lifting mechanism on the base over pulleys near the top of the tower to the jib tip and after a triple run between the jib tip and the tower top via fixed large cable pulleys to the lifting frame of the load carrying arrangement, to which it is fixed. The cable pulleys are mounted on a linkage and move on an approximately horizontal path when the jib tilts. The arrangement has a lifting cable (9.1,9.2) for the load carrying arrangement (10). It passes from a lifting mechanism (8.1,8.2) on the base of the crane over direction-changing pulleys near the top of the tower to the rocker jib (7) tip, and after a triple run between the jib tip and the tower top via fixed large cable direction changing pulleys (15) to the lifting frame of the load carrying arrangement, to which it is fixed. The cable direction changing pulleys are mounted on a linkage (13) and move on an approximately horizontal path when the jib tilts.

Description

Die Erfindung betrifft eine Lastführung an einem Hafenmobilkran zum kombinierten Container- und Schüttgutumschlag, insbesondere an einem Hafenkran mit einem am Turm angelenkten Wippausleger, an dessen freiem Ende die zum Be- und Entladen von Schiffen vorgesehenen Lastaufnahmemittel auswechselbar befestigt sind.The invention relates to a load management on a mobile harbor crane for the combined Container and bulk goods handling, especially on a harbor crane with an am Tower articulated luffing jib, at the free end of which is used for loading and unloading Load suspension devices provided by ships are interchangeably attached.

Die Umschlagleistung eines Hafenmobilkranes ist unter anderem abhängig von der Pendelbewegung, die die Last während des Transportes ausführt. Die Pendellänge eines herkömmlichen Wippkranes ist umgekehrt proportional der Ausleger-Ausladung, d.h. die minimale Pendellänge ist bei maximaler Ausleger-Ausladung und die maximale Pendellänge bei minimaler Ausleger-Ausladung zu verzeichnen. Das Problem der nachteiligen Pendelbewegung ergibt sich also insbesondere dann, wenn bei starken Wippbewegungen des Kranauslegers zwischen maximaler und minimaler Ausleger-Ausladung gearbeitet werden muß. Zu starke Pendelbewegungen der Last beim Wippen des Auslegers vermeiden Kranführer durch frühzeitige Reduzierung der Wippgeschwindigkeit. Das führt zu einer starken Beschränkung der Umschlagleistung.The handling capacity of a mobile harbor crane depends, among other things, on the Pendulum movement that carries the load during transportation. The pendulum length of a conventional luffing crane is inversely proportional to the jib radius, i.e. the minimum pendulum length is at maximum boom radius and maximum pendulum length with minimum boom outreach. The The problem of disadvantageous pendulum movement arises in particular when with strong luffing movements of the crane boom between maximum and minimum Boom radius must be worked. Pendulum movements of the load that are too strong Avoid crane operators when luffing the jib by reducing the Rocking speed. This leads to a strong limitation of the Handling performance.

Aufgabe der vorliegenden Erfindung ist es, ausgehend von den geschilderten Problemen und Nachteilen des Standes der Technik, eine Lastführung an einem Hafenmobilkran, insbesondere solchen mit an einem Turm angelenkten Wippausleger so zu gestalten, daß ohne Betätigung des Hubwerkes die Pendellänge zwischen Lastführung und Last möglichst bei allen Auslegerneigungen gleich gering ist.The object of the present invention is based on the described Problems and disadvantages of the prior art, a load management on one Mobile harbor crane, especially one with a luffing jib articulated on a tower so that the pendulum length between Load guidance and load are as small as possible with all boom inclinations.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgesehen, daß die Hubseile für das Lastaufnahmemittel von den an der Basis des Kranes angeordneten Hubwerken über im Bereich der Turmspitze angeordnete Umlenkrollen zur Auslegerspitze verlaufen und nach dreifacher Einscherung zwischen Auslegerspitze und Turmspitze über unterhalb der Wippauslegerspitze befestigte großdimensionierte Seilumlenkrollen zum Hubrahmen des Lastaufnahmemittels geführt und dort befestigt sind, wobei die Seilumlenkrollen koaxial am auskragenden Ende eines in der vorderen Hälfte des Wippauslegers angelenkten Lenkers gelagert sind und unter Ausnutzung der kinematischen Anordnung des Lenkers beim Wippen des Wippauslegers auf eine annähernd horizontalen Bahn bewegbar sind.To achieve the object, the invention provides that the hoisting ropes for the Load handling devices from the lifting devices arranged at the base of the crane Deflection rollers arranged in the area of the tower tip run to the jib tip and after triple reeving between the jib tip and the tower tip Below the luffing jib tip, large dimensioned pulleys are attached to the Lift frame of the load handler guided and fastened there, the Cable pulleys coaxial at the projecting end of one in the front half of the Luffing jib articulated handlebars are stored and using the Kinematic arrangement of the handlebars on the luffing jib on a approximately horizontal path are movable.

Mit einem derart ausgerüsteten Gerät, bei dem das Pendeln der Last durch Seilumlenkrollen weitgehend beschränkt wird, indem diese Seilumlenkrollen auf einer annähernd horizontalen Bahn bewegt werden, weil sie an einem am Wippausleger befestigten Lenker angeordnet sind, lassen sich die Umschlagleistung des Gerätes deutlich erhöhen. Durch schnelleres Aufnehmen- und insbesondere Absetzen der Last am Bestimmungsort sind Steigerungen der Umschlagleistung ca. 15 % möglich, was die Liegezeiten der Schiffe entsprechend verkürzt. Da die Liegezeiten sehr kostenintensiv sind, bedeutet eine Erhöhung der Umschlagleistung unmittelbar eine Kostenerspamis.With a device equipped in such a way that the load oscillates through Rope pulleys is largely limited by this rope pulleys on a approximately horizontal path, because they are on a luffing jib attached handlebars are arranged, the handling capacity of the device increase significantly. By picking up and, in particular, settling faster Load at the destination, increases in handling capacity are possible approx. 15%, which shortens the laydown times of the ships accordingly. Because the lay times are very are cost-intensive, an increase in throughput immediately means one Cost savings.

Dadurch, daß die Seilumlenkrollen am Ende des Lenkers einerseits stabilisiert sind und andererseits auf der horizontalen Bahn bewegt werden, verändert sich der Abstand zwischen der Seilumlenkrolle und dem Lastaufnahmemittel kaum, so daß, ausgehend von einer konstanten Hubhöhe, die Pendellänge zwischen Rolle und Last annähernd gleich bleibt, gleichgültig welche Neigung der Ausleger einnimmt.Characterized in that the rope pulleys are stabilized on the one hand at the end of the handlebar and on the other hand are moved on the horizontal path, the changes There is hardly any distance between the cable pulley and the load handler, so that based on a constant lifting height, the pendulum length between the roller and the load remains approximately the same, regardless of the inclination of the boom.

Vorzugsweise werden die Seilumlenkrollen von einem in ihrer Mitte befestigten Halteseil gehalten, das über an der Wippauslegerspitze angeordnete Umlenkrollen nach ebenfalls dreifacher Einscherung in den Bereich der Turmspitze geführt und dort befestigt ist. Analog zur dreifachen Einscherung der Hubseile, die den horizontalen Lastweg am Lastaufnahmemittel bewirkt, wird auch die Mitte der Seilumlenkrolle geführt, was der weiteren Stabilisierung des Systems und damit der Verhinderung der Lastpendelbewegung dient. Der größte Teil des Eigengewichtes der Lastführung wirkt nach der vorgesehenen Anordnung des Halteseils als Zugkraft, die den durch die Mehrfacheischerung des Halteseils entstehenden Reibungskräften entgegensteht. The cable deflection rollers are preferably fastened by one in their center Holding rope held, the over arranged on the luffing jib pulleys after also triple reeving into the area of the spire and there is attached. Analogous to triple reeving of the hoisting ropes, which are horizontal The load path on the load handler also causes the middle of the rope pulley led what the further stabilization of the system and thus the prevention of Load pendulum movement serves. Most of the dead weight of the load control works according to the intended arrangement of the tether as a tensile force caused by the Multiple friction of the tether prevents the resulting frictional forces.

Wenn nach einem weiteren Merkmal der Erfindung die Hubseile unterhalb der der Seilumlenkrollen parallel geführt sind, so wird dadurch eine zusätzliche Stabilisierung des Lastaufnahmemittels und damit der Last bewirkt.If according to a further feature of the invention, the hoisting ropes below the Cable pulleys are guided in parallel, so this is an additional stabilization of the load suspension device and thus the load.

Durch die vorteilhafte Lösung der vorliegenden Erfindung ist die Größe des Lastpendelns nur noch durch die Wippbewegung des Auslegers und dessen Last bestimmt. Dadurch, daß, ausgehend von einer konstanten Hubhöhe, die Pendellänge zwischen der Umlenkrolle des Lenkers und des Lastaufnahmemittels annähernd gleich bleibt, wird die beabsichtigte Steigerung der Umschlagleistung und damit die Kostenersparnis beim Umschlag von Stück- und Schüttgüten erreicht.Due to the advantageous solution of the present invention, the size of the Load oscillation only by the luffing movement of the boom and its load certainly. The fact that, based on a constant lifting height, the pendulum length approximately between the deflection roller of the handlebar and the load handler remains the same, the intended increase in throughput and thus the Cost savings achieved when handling piece and bulk goods.

Prinzipiell basiert die vorliegende Erfindung auf der Anwendung des bei Wippdrehkranen bekannten Einfachlenkersystems, kombiniert mit der teilweisen vorteilhaften Nutzung des Doppellenkersystems ("Unstetigförderer 1" von Prof. Dr.-lng. tech. h.c. F.KURTH, Seiten 138 - 139, Pkt. 3.6.2.3. und 3.6.2.4).In principle, the present invention is based on the application of the The luffing crane known single-link system, combined with the partial advantageous use of the double link system ("discontinuous conveyor 1" by Prof. Dr.-lng. tech. h.c. F.KURTH, pages 138 - 139, point 3.6.2.3. and 3.6.2.4).

Analog zum Spitzenausleger eines Doppellenkersystems bewegt sich die Seilrolle des Hafenmobilkranes auf der annähernd waagerechten Bahn; die Ermittlung und Festlegung der Anlenkpunkte am Wippausleger zur Schwenklagerung des Lenkers kann somit nach den bei Doppellenkersystems bekannten Verfahren erfolgen.
