Description

Die Erfindung betrifft ein Anbaugerät für einen Gabelstapler zum Transport einer Pfanne, insbesondere einer Pfanne mit schmelzflüssigem Inhalt, wie einer Gießpfanne, wobei der Gabelstapler ein Hubgerüst mit Kupplungseinrichtungen und Führungseinrichtungen zum lösbaren Ankuppeln und Führen eines Gabelträgers umfasst, wobei Kupplungseinrichtungen und Führungseinrichtungen des Anbaugeräts, die mit den Kupplungs- und Führungseinrichtungen des Hubgerüsts des Gabelstaplers zusammenwirken, sowie Einrichtungen zur Aufnahme und Sicherung der Pfanne vorgesehen sind. Die Erfindung betrifft weiter einen Gabelstapler mit einem Hubgerüst, das Kupplungseinrichtungen und Führungseinrichtungen zum lösbaren Ankuppeln und Führen eines Gabelträgers umfasst, und mit einem Anbaugerät zum Transport einer Pfanne.The invention relates to an attachment for a forklift for transporting a pan, in particular a ladle with molten content, such as a ladle, wherein the forklift comprises a mast with coupling devices and guide means for releasably coupling and guiding a fork carriage, wherein coupling means and guide means of the attachment, the interact with the coupling and guide means of the mast of the forklift, and means are provided for receiving and securing the pan. The invention further relates to a forklift with a mast comprising coupling means and guide means for releasably coupling and guiding a fork carriage, and to an attachment for transporting a pan.

Zum Transport von Gießpfannen werden nicht selten Gabelstapler eingesetzt, auf deren Gabeln die Gießpfannen transportiert werden. Dadurch kann der Gabelstapler vielseitiger eingesetzt werden, nämlich sowohl zum Transport von Gießpfannen als auch zum Transport anderer Lasten. Aufgrund der großen Stückzahl, in welcher Gabelstapler hergestellt werden, sind sie außerdem preiswerter als spezielle Flurfördermittel zum Transport von Gießpfannen oder anderen Pfannen mit schmelzflüssigem Inhalt. Der Transport von Pfannen mit schmelzflüssigem Inhalt auf den Gabelzinken von Gabelstaplern verursacht jedoch immer wieder schwere Unfälle, die vor allem auf eine mangelnde Sicherung der Pfannen zurückzuführen sind, was im Falle eines abrupten Bremsvorgangs zum Herabrutschen der Pfanne von den Gabelzinken führen kann. Ein weiterer Nachteil beim Transport einer Pfanne auf den Gabelzinken eines Gabelstaplers besteht darin, dass zwischen dem Hubgerüst und der Gießpfanne der entlang des Hubgerüsts auf und ab bewegliche Gabelträger untergebracht werden muss. Dies führt zu einer Verlagerung des Schwerpunkts der Pfanne vom Hubgerüst und von der Vorderachse des Staplers weg nach vorne, wodurch die maximale Nutzlast beim Transport gefüllter Pfannen erheblich abnimmt.
Ein Anbaugerät der eingangs genannten Art, welches die Merkmale des Oberbegriffs des Anspruchs 1 aufweist, ist aus der DE 21 60 533 A bekannt. DE 21 60 533 A beschreibt ein Anbaugerät mit einen Schwenktrieb, mit dem sich die Pfanne um eine allgemein vertikale Achse schwenken lässt. Der Schwenktrieb ist oberhalb der Pfanne angeordnet. Nachteilig daran ist, dass das bekannte Anbaugerät nur eine geringe Transportsicherheit aufweist, da die Sicht des Fahrers auf dem Fahrweg und die Pfanne durch die konstruktive Ausgestaltung des Anbaugeräts eingeschränkt ist. Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Anbaugerät und einen Gabelstapler für das erfindungsgemäße Anbaugerät der eingangs genannten Art dahingehend zu verbessern, dass beim Transport von Pfannen, insbesondere Pfannen mit einem schmelzflüssigen Inhalt, die Transportsicherheit verbessert und die Nutzlast erhöht werden kann, ohne die Transportkosten zu erhöhen und die vielseitigen Einsatzmöglichkeiten des Gabelstaplers zu beeinträchtigen.For the transport of ladles are often used forklifts on the forks of the ladles are transported. As a result, the forklift can be used more versatile, namely both for the transport of ladles and for the transport of other loads. Due to the large number of forklifts being manufactured, they are also cheaper than special floor conveyors for transporting ladles or other pans with molten content. However, the transport of pans with molten content on the forks of forklifts always causes serious accidents, which are mainly due to a lack of securing the pans, which can lead in the case of an abrupt braking to slide down the pan of the forks. Another disadvantage when transporting a pan on the forks of a forklift is that between the mast and the ladle along the mast movable up and down fork carrier must be accommodated. This leads to a shift of the center of gravity of the pan from the mast and from the front axle of the truck forward, whereby the maximum payload during transport filled pans decreases considerably.
An attachment of the type mentioned, which has the features of the preamble of claim 1, is known from DE 21 60 533 A known. DE 21 60 533 A describes an attachment with a swivel drive, with which the pan can pivot about a generally vertical axis. The swivel drive is arranged above the pan. The disadvantage of this is that the known attachment has only a low transport safety, since the driver's view of the track and the pan is limited by the structural design of the attachment. Proceeding from this, the present invention seeks to improve an attachment and a forklift for the attachment according to the invention of the type mentioned in that during the transport of pans, in particular Pans with a molten content that improves transport safety and increases payload, without increasing transportation costs and compromising the versatility of the forklift.

Diese Aufgabe wird bei dem Anbaugerät erfindungsgemäß dadurch gelöst, dass das Anbaugerät einen unterhalb der Pfanne angeordneten Schwenktrieb aufweist, mit dem sich die im Anbaugerät aufgenommene Pfanne um eine allgemein vertikale Achse schwenken lässt.This object is achieved in the attachment according to the invention in that the attachment has a pivot drive arranged below the pan, with which the pan received in the attachment can pivot about a generally vertical axis.

Durch die erfindungsgemäße Merkmalskombination wird erreicht, dass preiswerte Gabelstapler wahlweise mit dem Anbaugerät zum Transport einer Pfanne oder mit einem Gabelträger nebst Gabelzinken zum Transport von anderen Lasten eingesetzt und damit die Transportkosten reduziert werden können. Zudem muss beim Transport einer Pfanne zwischen dem Hubgerüst und dem Anbaugerät kein Platz für den Gabelträger frei gehalten werden, so dass der Schwerpunkt der Pfanne näher an das Hubgerüst und an die Vorderachse heran verlegt und dadurch bei gegebener Traglast des Gabelstaplers die Transportkapazität erhöht werden kann. Durch das Fehlen des Gabelträges kann weiter die Sicht des Fahrers auf den Fahrweg und auf die Pfanne verbessert werden. Darüber hinaus stellen die Einrichtungen zur Aufnahme und Sicherung der Pfanne im Anbaugerät sicher, dass die Pfanne beim Transport nicht verrutschen oder auf andere Weise ihre Lage verändern kann und gewährleisten daher eine hohe Transportsicherheit. Indem erfindungsgemäß das Anbaugerät einen unterhalb der Pfanne angeordneten Schwenkantrieb aufweist, mit dem sich die im Anbaugerät aufgenommene Pfanne um eine im Allgemeinen vertikale Achse schwenken lässt, wird der Aktionsradius des erfindungsgemäßen Anbaugeräts vergrößert, da sich die Pfanne und ein Kippbügel in Bezug zum Tragmast des das erfindungsgemäße Anbaugerät verwendenden Gabelstaplers aus seiner Transportstellung um jeweils etwa 90° im Uhrzeigersinn sowie auch entgegen dem Uhrzeigersinn um die vertikale Schwenkachse schwenken lassen. Durch die Anordnung des Schwenkantriebs unterhalb von der Pfanne kann die Sicht des Fahrers auf den Fahrweg und die Pfanne verbessert und die Bauhöhe des mit dem Anbaugerät ausgestatteten Gabelstaplers verringert werden, so dass die Pfanne auch durch niedrige Tordurchfahrten oder unter sonstigen Überbauungen hindurch transportiert werden kann. Außerdem bleiben die Pfanne und die Oberfläche der Schmelze von oben her frei zugänglich, was zum Beispiel eine Behandlung oder Reinigung der Schmelze oder eine Beheizung der Pfanne erleichtert.The combination of features according to the invention ensures that inexpensive forklift trucks can be used either with the attachment for transporting a pan or with a fork carriage together with forks for the transport of other loads and thus the transport costs can be reduced. In addition, no space for the fork carriage must be kept free during transportation of a pan between the mast and the attachment so that the focus of the pan moves closer to the mast and to the front axle and thereby the transport capacity can be increased at a given load of the forklift. Due to the absence of the fork carrier can further improve the driver's view of the track and on the pan. In addition, the device for receiving and securing the pan in the attachment ensure that the pan can not slip during transport or otherwise change their position and therefore ensure a high transport safety. According to the invention, the attachment has a arranged below the pan pivot drive, with which the pan received in the attachment can pivot about a generally vertical axis, the radius of action of the attachment according to the invention is increased, since the pan and a tilt bracket with respect to the support mast of the Inventive implement using forklift from Its transport position can be pivoted about 90 ° clockwise as well as counterclockwise about the vertical pivot axis. The arrangement of the pivot drive below the pan can improve the driver's view of the track and the pan and the height of the equipped with the attachment forklift can be reduced, so that the pan can be transported through low gate passages or under other superstructures. In addition, the pan and the surface of the melt remain freely accessible from above, which facilitates, for example, a treatment or cleaning of the melt or heating of the pan.

Der Schwenkantrieb ist zweckmäßig zwischen dem Tragmast und einer Grundplatte des Anbaugeräts angeordnet, die den Kippbügel mit der Pfanne und die übrigen Teile des Anbaugeräts trägt, so dass diese zusammen mit der Grundplatte in Bezug zum Tragmast schwenkbar sind. Dabei ist der Schwenkantrieb vorzugsweise so angeordnet, dass die Schwenkachse durch die Mitte der allgemein kreisförmigen Pfanne verläuft, wodurch eine Verlagerung des Lastschwerpunkts beim Verschwenken der Pfanne vermieden wird.The pivot drive is suitably arranged between the support pole and a base plate of the attachment, which carries the tilt bracket with the pan and the other parts of the attachment, so that they are pivotable together with the base plate with respect to the support mast. In this case, the pivot drive is preferably arranged so that the pivot axis extends through the center of the generally circular pan, whereby a shift of the load center of gravity during pivoting of the pan is avoided.

Bei dem Gabelstapler wird die Aufgabe erfindungsgemäß dadurch gelöst, dass der Gabelstapler das erfindungsgemäße Anbaugerät verwendet, und dass das Anbaugerät Kupplungseinrichtungen und Führungseinrichtungen aufweist, die mit den Kupplungs- und Führungseinrichtungen des Hubgerüsts zusammenwirken.In the forklift, the object is achieved in that the forklift uses the attachment according to the invention, and that the attachment has coupling means and guide means which cooperate with the coupling and guide means of the mast.

Die für das erfindungsgemäße Anbaugerät besonders geeignete Pfanne oder den das erfindungsgemäße Anbaugerät verwendenden Gabelstapler sieht gemäß einer vorteilhaften Weiterbildung der Erfindung des weiteren vor, dass das Pfannenoberteil eine einseitig überstehende Ausgießschnauze aufweist, und dass vorzugsweise der Pfannenkörper der Pfanne einen Wechselboden aufweist, der vorzugsweise mit dem Pfannenoberteil entlang einer Flanschverbindung verbunden ist.The particularly suitable for the attachment according to the invention pan or the attachment according to the invention using forklift provides according to an advantageous embodiment of the invention further, that the pan shell has a one-sided projecting Ausgießschnauze, and preferably that the pan body of the pan a removable bottom which is preferably connected to the pan top along a flange connection.

Eine weitere bevorzugte Weiterbildung der Erfindung sieht vor, dass die Kupplungs- und Führungseinrichtungen dieselben Anschlussmaße wie die Kupplungs- und Führungseinrichtungen am Gabelträger aufweisen, so dass die Kupplungs- und Führungseinrichtungen des Anbaugeräts und des Gabelträgers gut zu den komplementären Kupplungs- und Führungseinrichtungen des Hubgerüsts passen und somit ein Austausch des Anbaugeräts und des Gabelträgers keine zusätzlichen Teile am Hubgerüst erforderlich macht.A further preferred embodiment of the invention provides that the coupling and guide devices have the same connection dimensions as the coupling and guide means on the fork carriage, so that the coupling and guide means of the attachment and the fork carriage fit well with the complementary coupling and guide means of the mast and thus replacement of the attachment and the fork carriage does not require any additional parts on the mast.

Dadurch kann das Anbaugerät mittels der Kupplungseinrichtungen in derselben Art und Weise wie der Gabelträger an den Hubketten des Hubgerüsts aufgehängt und gesichert werden. Außerdem werden der Gabelträger und das Anbaugerät nach dem Kuppeln mit den Kupplungseinrichtungen des Hubgerüsts jeweils derart von den Hubketten des Hubgerüsts getragen, dass sie mittels eines hydraulischen Antriebs der Hubketten bei Bedarf als Ganzes angehoben oder abgesenkt werden können, zum Beispiel zum Entleeren der im Anbaugerät transportierten Pfanne.Thereby, the attachment can be suspended and secured by means of the coupling means in the same manner as the fork carriage on the lifting chains of the mast. In addition, the fork carriage and the attachment after coupling with the coupling means of the mast are each supported by the lifting chains of the mast so that they can be raised or lowered by means of a hydraulic drive of the lifting chains as needed as a whole, for example, to empty the transported in the attachment Pan.

Dadurch kann das Anbaugerät mit der gefüllten Pfanne auf dem Untergrund abgestellt werden, wenn sich der Gabelstapler in einer Ruheposition oder Wartestellung befindet oder wenn die Schmelze in der Pfanne behandelt wird, wodurch der Hubantrieb und die Hubketten des Gabelstaplers entlastet werden können. Außerdem kann das Anbaugerät zum Beispiel zum Entleeren der Pfanne in eine beliebige gewünschte Höhe angehoben werden.This allows the attachment to be placed on the ground with the pan filled when the forklift is in a rest or standby position or when the melt is being handled in the ladle, thereby relieving the lift drive and lift chains of the forklift. In addition, the attachment can be raised, for example, to empty the pan to any desired height.

Die Kupplungs- und Führungseinrichtungen des Anbaugeräts sind vorteilhaft in einen Tragmast integriert, der an der zum Stapler benachbarten Seite des Anbaugeräts angeordnet ist und zweckmäßig dieselben Anschlussmaße und Bauteile wie der Gabelträger aufweist, wie Führungsrollen, Rollenbolzen, Hubkettenanschlüsse oder Anschläge. Dadurch kann der Einbau des Tragmasts in das Hubgerüst des Gabelstaplers ohne bauliche Veränderungen am Gabelstapler bzw. an dessen Hubgerüst vorgenommen werden.The coupling and guide means of the attachment are advantageously integrated in a support pole, which is arranged on the side adjacent to the stacker of the attachment and expediently having the same connection dimensions and components as the fork carriage, such as guide rollers, roller bolts, Hubkettenanschlüsse or stops. As a result, the installation of the support mast in the mast of the forklift can be made without structural changes to the forklift or on the mast.

Bevorzugt sind an den entgegengesetzten Seiten des Anbaugeräts zwei aufrechte Kippzylinder vorgesehen, die sich mit ihren unteren Enden bzw. ihren Zylinderrohren gelenkig auf einer Grundplatte des Anbaugeräts abstützen. Die Kippzylinder sind vorteilhaft mit ihren oberen Enden bzw. ihren Kolbenstangen an einer starr mit dem Kippbügel verbundenen Schwinge angelenkt, so dass sich durch Ausfahren der Kolbenstangen der Kippbügel zusammen mit der Pfanne aus einer allgemein horizontalen Ruhestellung um etwa 95 Grad in eine allgemein senkrechte Entleerstellung verschwenken lässt. Die horizontale Schwenkachse des Kippbügels ist vorteilhaft in der Nähe einer Ausgießschnauze der Pfanne angeordnet, so dass die Ausgießschnauze beim Kippen der Pfanne ihre Lage beibehält und der Gießstrahl beim Ausgießen nicht wandert, was ein zielgenaues Eingießen in eine Gießöffnung einer Gussform ermöglicht.In order for the ladle transported by the stacker to empty, the means for receiving and securing the pan according to an advantageous development of the attachment and this forklift advantageously use a tilt bracket for hanging the pan and at least one hydraulic tilt cylinder for tilting the tilting bracket and the tilting bar hinged pan. Preferably, two upright tilt cylinders are provided on the opposite sides of the attachment, which are articulated with their lower ends or their cylinder tubes on a base plate of the attachment. The tilting cylinders are advantageously articulated with their upper ends or their piston rods on a rigidly connected to the tilting rocker, so that pivoting by extending the piston rods of the tilt bracket together with the pan from a generally horizontal rest position by about 95 degrees in a generally vertical emptying leaves. The horizontal pivot axis of the tilting bracket is advantageously arranged in the vicinity of a pouring spout of the pan, so that the pouring spout retains its position during tilting of the pan and the pouring stream does not migrate during pouring, which enables precise pouring into a pouring opening of a casting mold.

Zur Vergrößerung des Aktionsradius beim Gießen umfasst das Anbaugerät gemäß einer weiteren bevorzugten Weiterbildung der Erfindung einen unterhalb der von Pfanne angeordneten hydraulischen Schwenkantrieb, mit dem sich die Pfanne und der Kippbügel in Bezug zum Tragmast aus einer Transportstellung um jeweils etwa 90 Grad im Uhrzeigersinn sowie auch entgegen dem Uhrzeigersinn um eine allgemein vertikale Schwenkachse schwenken lassen.To increase the radius of action during casting, the attachment according to a further preferred embodiment of the invention comprises a below the pan arranged hydraulic rotary actuator with which the pan and the From a transport position, tilt the tilting stirrup clockwise and counter-clockwise by about 90 degrees each around a generally vertical pivot axis.

Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung umfasst das Anbaugerät einen hydraulisch schwenkbaren Deckel, der sich bei Bedarf auf die im Anbaugerät aufgenommene Pfanne absenken lässt, um eine Einfüllöffnung an der Oberseite der Pfanne und vorteilhaft auch eine Öffnung an der Oberseite der Ausgießschnauze zu verschließen. Auf diese Weise kann beim Transport der Pfanne ein ungewollter Austritt des flüssigen Pfanneninhalts zum Beispiel beim Bremsen verhindert und damit die Sicherheit verbessert werden. Außerdem werden durch den Deckel die Wärmeverluste verringert und damit das Abkühlen des Inhalts der Pfanne verlangsamt. Der Deckel ist zweckmäßig an der zum Stapler benachbarten Seite des Kippbügels angelenkt und umfasst vorteilhaft einen ersten Deckelteil zum Verschließen der oberen Einfüllöffnung und einen in Bezug zum ersten Deckelteil beweglichen zweiten Deckelteil zum Verschließen der Öffnung an der Oberseite der Ausgießschnauze sowie einer Ausgießöffnung der Pfanne.According to a further advantageous embodiment of the invention, the attachment comprises a hydraulically pivotable lid, which can be lowered if necessary on the pan received in the attachment, to close a filling opening at the top of the pan and advantageously also an opening at the top of the pouring spout. In this way, during transport of the pan, an undesired escape of the liquid pan contents, for example during braking, can be prevented and thus the safety can be improved. In addition, the heat loss is reduced by the lid and thus slows down the cooling of the contents of the pan. The cover is expediently articulated on the side of the tilting bracket adjacent to the stacker and advantageously comprises a first cover part for closing the upper filling opening and a second cover part movable relative to the first cover part for closing the opening at the top of the pouring spout and a pouring opening of the pan.

Vorteilhaft ist der erste Deckelteil um eine erste horizontale Schwenkachse in Bezug zum Kippbügel schwenkbar, während der zweite Deckelteil um eine zur ersten Schwenkachse parallele zweite Schwenkachse in Bezug zum ersten Deckelteil schwenkbar ist. Der zweite Deckelteil kann zweckmäßig unabhängig vom ersten Deckelteil geöffnet und geschlossen werden, wodurch es ermöglicht wird, beim Transport sowohl den ersten und den zweiten Deckelteil und im Gießbetrieb nur den ersten Deckelteil zu schließen.Advantageously, the first cover part is pivotable about a first horizontal pivot axis with respect to the tilt bracket, while the second cover part is pivotable about a second pivot axis parallel to the first pivot axis with respect to the first cover part. The second cover part can be suitably opened and closed independently of the first cover part, which makes it possible to close both the first and the second cover part during transport and only the first cover part in the casting operation.

Eine weitere bevorzugte Weiterbildung der Erfindung sieht vor, dass das Anbaugerät eine Gießrinne umfasst, die aus einer Gebrauchsstellung vor einer Ausgießschnauze der Pfanne in eine Nichtgebrauchsstellung neben der Pfanne schwenkbar ist. Auf diese Weise kann der Inhalt der Pfanne in Abhängigkeit von der Zugänglichkeit oder Erreichbarkeit einer Gießöffnung einer Gussform wahlweise direkt aus der Pfanne oder indirekt durch die Gießrinne in die Gießöffnung gegossen werden. Dabei wird die Gießrinne zweckmäßig dann eingesetzt, wenn die Gießöffnung schwer zugänglich oder flureben ist oder zwischen dem Fahrweg des Staplers und der Gießöffnung große Abstände überbrückt werden müssen.A further preferred embodiment of the invention provides that the attachment comprises a runner, which is pivotable from a use position in front of a pour spout of the pan in a non-use position next to the pan. In this way, the content of the pan depending on the accessibility or accessibility of a pouring opening of a mold optionally be poured directly from the pan or indirectly through the trough into the pouring opening. The runner is expediently used when the pouring opening is difficult to access or flute, or between the track of the truck and the pouring large distances must be bridged.

Vorteilhaft ist die Gießrinne in der Gebrauchsstellung allgemein in Fahrtrichtung des Staplers ausgerichtet, während sie in der Nichtgebrauchsstellung allgemein entgegen der Fahrtrichtung ausgerichtet ist, so dass sie den Gießvorgang nicht behindert, wenn aus der Pfanne direkt in die Gießöffnung gegossen wird.Advantageously, the runner in the position of use is generally oriented in the direction of travel of the truck, while it is oriented in the non-use position generally opposite to the direction of travel, so that it does not interfere with the casting process, when poured from the pan directly into the pouring opening.

Vorteilhaft umfasst das Anbaugerät außerdem Einrichtungen, mit denen sich in der Gebrauchsstellung der Neigungswinkel der Gießrinne verändern lässt, um diese wahlweise nach oben in eine Fahrstellung oder mit einem beliebigen Neigungswinkel nach unten in eine Gießstellung zu schwenken.Advantageously, the attachment also includes means with which can be changed in the position of use of the inclination angle of the trough to this optional upward in a Driving position or with any inclination angle down to a casting position to pivot.
