Gemäß der Erfindung hat der Motorantrieb einen Elektromotor, der über ein Getriebe, vorzugsweise ein Stirnzahnradgetriebe, mit einer den jeweiligen Schwenkarm (36) drehenden Antriebswelle (32) verbunden ist, die über eine energiespeichernde Torsionsdämpfungs-Kupplung (30) mit dem Schwenkarm (26) gekoppelt ist.The spreader serves to receive a container (10) at its corner fittings (12) by means of spreader (18) mounted pivot (Twistlocks 16), which pivotal Einweiser (pinball 24) are associated with pivot arms, which are connected to a motor drive. According to the invention, the motor drive has an electric motor which is connected via a transmission, preferably a spur gear, to a drive shaft (32) which rotates the respective pivot arm (36) and which is connected to the pivot arm (26) via an energy-storing torsion damping coupling (30). is coupled.
Description
Die Erfindung betrifft einen Spreader zur Aufnahme eines Containers an dessen Eckbeschlägen mittels am Spreader angebrachter Drehzapfen (Twistlocks), denen jeweils schwenkbare Einweiser (Flipper) mit Schwenkarmen zugeordnet sind, die mit einem Motorantrieb verbunden sind.The The invention relates to a spreader for receiving a container at the corner fittings by means of on the spreader mounted pivot (twist locks), which each swiveling Einweiser (Flipper) are associated with swivel arms, which are connected to a motor drive.
Zum Heben von Container für den Land- und Seetransport werden Spreader eingesetzt, die über Seile oder Ketten an einem Kran hängen, der sie an die jeweils gewünschte Stelle verfährt. An allen vier Ecken der Oberseite des Containers sind hierzu Eckbeschläge mit schlitzförmigen Ausnehmungen angebracht, in die die Drehzapfen (Twistlocks) des Spreaders eingreifen und danach durch eine Verdrehung um 90° verriegelt werden müssen. Da durch die Kranbewegung der Spreader in starke Schwingungen und Schwankbewegungen gerät, ist es nahezu unmöglich, die Twistlocks exakt in die Ausnehmungen der Eckbeschläge einzuführen. In Anbetracht der erforderlichen Umschlaggeschwindigkeit von etwa 30 Container in der Stunde sind daher Einweiser erforderlich, d. h. über einen geeigneten Antrieb betätigte Flipper mit Schwenkarmen, die beim Aufsetzen des Spreaders auf den Container den Spreader in eine zentrierte Lage über den Container ziehen. Der Kraftbedarf zum zentrierten Aufsetzen („Fangen") des Spreaders auf einem Container liegt etwa zwischen 1.500 und 3.200 N.To the Lifting container for For land and sea transport spreaders are used, which are over ropes or hang chains on a crane, which you to the respectively desired Body moves. At all four corners of the top of the container for this purpose are corner fittings with slot-shaped recesses mounted, in which engage the pivots (Twistlocks) of the spreader and then locked by a 90 ° twist. There by the crane movement of the spreader into strong vibrations and oscillatory movements device, it is almost impossible insert the twistlocks exactly into the recesses of the corner fittings. In Considering the required turnover rate of about 30 Container per hour, therefore, instructors are required, d. H. over one actuated suitable drive Flipper with swivel arms, which when placing the spreader on the Container pull the spreader into a centered position over the container. The power requirement for centering ("catching") the spreader a container is between about 1,500 and 3,200 N.
Aufgrund der erwähnten, starken Schwingbewegungen des Spreaders kommt erschwerend hinzu, dass während der Aufsetzbewegung des Spreaders zum Fangen des Containers die Flipper sehr starken Stößen ausgesetzt sind, die sich auf den Motorantrieb und das dazwischen geschaltete Getriebe schädlich auswirken.by virtue of the mentioned, strong swinging movements of the spreader adds to the difficulty, that while the Aufsetzbewegung the spreader to catch the container the Flipper exposed to very strong shocks which are on the motor drive and the intermediate one Gear harmful impact.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Spreader zur Verfügung zu stellen, bei dem die Antriebselemente für die Flipper so ausgebildet sind, dass sie einerseits eine sehr große Anstellkraft in der endgültigen Fangstellung auf den Container ausüben und andererseits gegen die starken Stoßkräfte wirkungsvoll geschützt sind.Of the The invention is therefore based on the object, a spreader available place, in which the drive elements for the pinball designed are, on the one hand, a very large adjusting force in the final catch position to exercise on the container and on the other hand are effectively protected against the strong impact forces.
Zur Lösung dieser komplexen Aufgabe ist erfindungsgemäß vorgesehen, dass der Motorantrieb einen Elektromotor hat, der über ein Getriebe, vorzugsweise ein Stirnzahnradgetriebe, mit einer den jeweiligen Schwenkarm drehenden Antriebswelle verbunden ist, die über eine energiespeichernde Torsionsdämpfungs-Kupplung mit dem Schwenkarm gekoppelt ist.to solution This complex task is inventively provided that the motor drive a Electric motor has that over a transmission, preferably a spur gear, with a each pivot arm rotating drive shaft is connected, which has a Energy-storing torsion damping coupling is coupled with the swivel arm.
Gegenüber bisher versuchten Lösungen mit hydraulischem Flipperantrieb oder mit einem Elektromotor-Antrieb und einem Schneckengetriebe hat die Erfindung den Vorteil, dass einerseits ein sehr hohes Drehmoment auf die Schwenkarme der Flipper ausgeübt wird, das in der Größenordnung von 3.000 Nm liegt, so dass der Spreader innerhalb kürzester Zeit in die zentrierte Position über dem Container gezogen werden kann. Andererseits unterstützt dabei die energiespeichernde Torsionsdämpfungs-Kupplung, die vorzugsweise vorgespannte, gummielastische Zwischenglieder hat, die Fangbewegung und die endgültige Klemmstellung, wobei gleichzeitig die auftretenden Schläge und Stöße durch die Kupplung der erwähnten Bauart elastisch abgefangen werden und sich nicht schädlich auf den Motorantrieb und das Getriebe auswirken.Opposite so far tried solutions with hydraulic flipper drive or with an electric motor drive and a worm gear, the invention has the advantage that on the one hand a very high torque on the swivel arms of the pinball machine exercised that's going to be on the order of magnitude of 3,000 Nm, allowing the spreader within the shortest possible time Time in the centered position over the container can be pulled. On the other hand, it supports the energy-storing torsion damping coupling, having preferably prestressed, rubber-elastic intermediate links, the catching motion and the final one Clamping position, at the same time the occurring shocks and shocks the coupling of the mentioned Type of elastic are intercepted and not harmful to affect the engine and the transmission.
In Weiterbildung der Erfindung ist vorgesehen, dass dem Schwenkarm ein Endschalter zum Ein- und Ausschalten des Elektromotors in Abhängigkeit von dem Verdrehwinkel des Schwenkarms zugeordnet ist. Dabei ist es vorteilhaft, wenn der Anstellwinkel des Endschalters eingestellt werden kann.In Further development of the invention is provided that the swivel arm a limit switch for switching on and off of the electric motor in dependence is assigned by the twist angle of the pivot arm. It is It is advantageous if the angle of attack of the limit switch is set can be.
Die zu Beginn des Fangens auf den Flipper wirkenden Stöße drücken den Schwenkarm aus seiner zunächst korrekten Fangstellung, wodurch der Endschalter den Elektromotor automatisch wieder einschaltet und die Antriebswelle über die gummielastischen Zwischenglieder den Flipper wieder in seine Spannstellung zurückzieht, wobei die elastischen Zwischenglieder weiter vorgespannt werden und die Spannkraft des Schwenkarms erhöhen.The At the beginning of catching, impacts on the flipper press the button Swivel arm from his first correct catch position, whereby the limit switch the electric motor automatically turns back on and the drive shaft over the rubber-elastic intermediate links the pinball back into its clamping position withdraws wherein the elastic intermediate members are further biased and increase the clamping force of the swivel arm.
