Description

Die Erfindung bezieht sich auf ein Lastteil für ein Flurförderzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a load part for a truck according to the preamble of patent claim 1.

Üblicherweise besteht das Lastteil eines Flurförderzeugs aus einer Lastgabel und einem Lastschlitten, an dem die Lastgabel angebracht ist. Der Lastschlitten weist Führungsrollen auf, die in einem Mast des Hubgerüsts geführt sind. Normalerweise sind zwei Rollenpaare am Lastschlitten gelagert.Usually, the load part of a truck consists of a fork and a load carriage on which the fork is mounted. The load carriage has guide rollers, which are guided in a mast of the mast. Usually two pairs of rollers are mounted on the load carriage.

Der Lastschlitten weist zumeist eine Frontplatte aus Stahl auf, an die Schlittenstege angeschweißt sind, an die ihrerseits die Rollenbolzen angeschweißt sind. Diese Konstruktion besteht somit aus drei Einzelteilen, wobei die aus Stegen und Rollenbolzen bestehenden Einzelteile als Schweißbaugruppe mit der Frontplatte verschweißt werden. Hierfür ist eine relativ komplex aufgebaute Schweißvorrichtung erforderlich. Ein weiterer Nachteil dieser Konstruktion ist die Gefahr von Ungenauigkeiten aufgrund eines Schweißverzuges.The load carriage usually has a front plate made of steel, are welded to the carriage webs, to which in turn the roller bolts are welded. This construction thus consists of three individual parts, whereby the individual parts consisting of webs and roller bolts are welded to the front plate as a welded assembly. For this purpose, a relatively complex constructed welding device is required. Another disadvantage of this design is the risk of inaccuracies due to welding distortion.

Der Erfindung liegt die Aufgabe zugrunde, ein Lastteil für ein Flurförderzeug zu schaffen, dessen Lastschlitten weniger aufwendig präzise herstellbar ist und einen geringeren Materialverbrauch aufweist.The invention has for its object to provide a load part for an industrial truck, the load carriage is less expensive to produce precisely and has a lower material consumption.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.

Bei der Erfindung bildet der Rollenbolzen einen Endabschnitt eines ersten Schenkels eines winkelförmigen Formelements, dessen zweiter Schenkel mit einem Endabschnitt mit der Frontplatte verbunden ist. Dabei muss es sich nicht im strengen Sinne um ein Winkelelement handeln. Entscheidend ist, dass ein Endabschnitt des zweiten Schenkels stumpf gegen die Frontplatte gerichtet ist, während der Schenkelabschnitt mit dem Rollenbolzen mit seiner Achse sich im Winkel dazu z.B. annähernd parallel beabstandet zur Frontplatte erstreckt.In the invention, the roller pin forms an end portion of a first leg of an angular shaped element whose second leg is connected to an end portion with the front panel. It does not have to be an angular element in the strict sense. What matters is that one end portion of the second leg is butted against the faceplate, while the leg portion with the roller bolt with its axis extending at an angle thereto, for example, approximately parallel spaced from the front panel.

Der erfindungsgemäße Lastschlitten besteht daher nur aus zwei Teilen und führt daher zu einem geringeren Materialverbrauch. Auch die einzusetzende Schweißvorrichtung ist relativ unaufwendig und wenig kompliziert. Außerdem lässt sich mit Hilfe der Erfindung eine präzise Anbringung der Rollenbolzen vornehmen.The load carriage according to the invention therefore consists only of two parts and therefore leads to a lower material consumption. The welding device to be used is relatively inexpensive and not very complicated. In addition, can be made with the help of the invention, a precise attachment of the roller bolt.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Nach einer Ausgestaltung der Erfindung kann das Formteil geschmiedet oder gegossen sein oder aus Vollmaterial durch mechanische Bearbeitung gefertigt werden. Eine Befestigung an der Frontplatte kann durch Schweißen, Schrauben oder Nieten erfolgen.According to one embodiment of the invention, the molding may be forged or cast or made of solid material by mechanical machining. An attachment to the front panel can be done by welding, screwing or riveting.

Nach einer Ausgestaltung der Erfindung ist der Endabschnitt des zweiten Schenkels als Klotz ausgebildet, der annähernd passend in einer Ausnehmung der Frontplatte eingesetzt ist. Es ist denkbar, das Ende des zweiten Schenkels stumpf gegen die zugeordnete zugekehrte Fläche der Frontplatte anzusetzen und dort zu verschweißen. Die vorherige Ausformung einer Ausnehmung einer Platte ermöglicht eine präzise Anbringung des Rollenbolzens. Außerdem wird die Belastung der Schweißnaht reduziert.According to one embodiment of the invention, the end portion of the second leg is formed as a block which is inserted approximately fitting in a recess of the front panel. It is conceivable to set the end of the second leg blunt against the associated facing surface of the front panel and to weld there. The previous formation of a recess of a plate allows a precise attachment of the roller bolt. In addition, the load on the weld is reduced.

Der Klotz kann einen kreisförmigen Querschnitt aufweisen, vorzugsweise ist jedoch eine polygonale Umfangsfläche vorgesehen, wobei die Kanten gerundet sind. Dadurch ist eine präzise Ausrichtung der Rollenbolzen möglich. Die Schweißnaht an der zugekehrten Fläche der Frontplatte ist um den zweiten Schenkel bzw. den Klotz herumgelegt.The block may have a circular cross-section, but preferably a polygonal peripheral surface is provided, wherein the edges are rounded. As a result, a precise alignment of the roller bolt is possible. The weld on the facing surface of the front panel is wrapped around the second leg or the pad.

Nach einer weiteren Ausgestaltung der Erfindung ist das Formteil mit dem Rollenbolzen einteilig geformt.According to a further embodiment of the invention, the molding is integrally formed with the roller bolt.

Nach einer anderen Ausgestaltung der Erfindung ist die den Rollenbolzen abgewandte Seite des zweiten Schenkels mit einer Schrägfläche versehen, derart, dass die Dicke des zweiten Schenkels in Richtung des ersten Schenkels stetig abnimmt. Dadurch ist bei einem Paar benachbarter Rollenbolzen der Zugang für die Schweißvorrichtung zum Legen der Schweißnaht um den zweiten Schenkel herum erleichtert. Die Schrägfläche sorgt ferner für einen geringeren Materialverbrauch und schafft schließlich Platz zwischen den Rollenbolzen für einen Hubzylinder. In der Schrägfläche kann eine Ausnehmung vorgesehen werden, die zum Halten beim Schweißen dient.According to another embodiment of the invention, the side facing away from the roller bolt side of the second leg is provided with an inclined surface, such that the thickness of the second leg decreases steadily in the direction of the first leg. Thereby, in a pair of adjacent roller bolts, access for the welding device for laying the weld around the second leg is facilitated. The inclined surface also ensures a lower material consumption and finally creates space between the roller bolts for a lifting cylinder. In the inclined surface, a recess can be provided, which serves to hold during welding.

Nach einer anderen Ausgestaltung der Erfindung ist ein an den Rollenbolzen angrenzender Abschnitt des ersten Schenkels im Querschnitt kreisförmig und mit einem größeren Durchmesser versehen als der des Rollenbolzens. Der Übergang ist vorzugsweise stufenförmig.According to another embodiment of the invention, an adjacent to the roller bolt portion of the first leg is circular in cross-section and provided with a larger diameter than that of the roller bolt. The transition is preferably stepped.

Der Übergang zum ersten Schenkel auf der Seite des Rollenbolzens ist nach einer weiteren Ausgestaltung der Erfindung gerundet. Der zweite Schenkel ist im Querschnitt vorzugsweise teilkreisförmig.The transition to the first leg on the side of the roller bolt is rounded according to a further embodiment of the invention. The second leg is preferably part-circular in cross-section.

Sind für zwei Rollenpaare vier Rollenbolzen vorgesehen, können diese identisch sein. Dies ist aber nicht obligatorisch. Damit ein besseres Abrollen ohne seitliche Reibung der Rollen am Mastprofil gewährleistet ist, haben zum Beispiel die oberen Rollenbolzen eine Neigung von der Gabel weg und die unteren eine Neigung zur Gabel hin. Diese Neigung kann vorzugsweise 2,5° betragen. Die Neigung kann durch unterschiedliche Ausfräsungen in der Frontplatte (Ausnehmungen) realisiert werden. Es ist aber auch möglich, zwei unterschiedliche Rollenbolzen zu verwenden und diese ohne Ausfräsungen in der Frontplatte diese zu verschweißen.If four roller bolts are provided for two pairs of rollers, these may be identical. But this is not obligatory. Thus, a better rolling is ensured without lateral friction of the rollers on the mast profile, for example, the upper roller bolts have a slope away from the fork and the lower an inclination towards the fork. This inclination may preferably be 2.5 °. The inclination can be realized by different cutouts in the front plate (recesses). But it is also possible to use two different roller pins and these without milling in the front panel to weld them.

In Figur 1 ist ein Lastteil 10 für ein Flurförderzeug gezeigt mit zwei Gabelarmen 12, 13 einer Lastgabel. Die Gabelarme 12, 13 sind in bekannter Weise an einem Lastschlitten 14 angebracht, beispielsweise durch Verschweißen. Hierauf wird im Einzelnen nicht eingegangen. Der Lastschlitten 14 besteht aus einer Frontplatte 16, an die auf der Rückseite parallel beabstandete Stege 18 angeschweißt sind. An die Außenseiten der Stege sind jeweils zwei Rollenbolzen angeschweißt, von denen einer bei 20 gezeigt ist. Hierbei handelt es sich um eine Konstruktion nach dem Stand der Technik. Die Rollen, die auf den Rollenbolzen 20 gelagert sind, werden in einem Mast eines Hubgerüsts geführt (nicht gezeigt).In FIG. 1 is a load part 10 for a truck shown with two fork arms 12, 13 of a fork. The fork arms 12, 13 are mounted in a known manner on a load carriage 14, for example by welding. This will not be discussed in detail. The load carriage 14 consists of a front plate 16, are welded to the back parallel spaced webs 18. To the outsides of the webs are each welded two roller bolts, one of which is shown at 20. This is a construction according to the prior art. The rollers, which are mounted on the roller bolt 20, are guided in a mast of a mast (not shown).

In den Figuren 2 und 3 ist eine Frontplatte 30 relativ ähnlich zu der nach Figur 1 dargestellt. Wie die Frontplatte 14 weist sie untere Ausnehmungen 32, 34 für die Verschweißung der Gabelarme 12, 13 auf. Im oberen Bereich der Frontplatte 30 sind zwei annähernd quadratische Ausnehmungen 34, 36 eingeformt. Ähnliche Ausnehmungen 38, 40 sind im unteren Bereich der Frontplatte 30 geformt.In the Figures 2 and 3 is a front plate 30 is relatively similar to the after FIG. 1 shown. As the front panel 14 has lower recesses 32, 34 for the welding of the fork arms 12, 13. In the upper region of the front plate 30, two approximately square recesses 34, 36 are formed. Similar recesses 38, 40 are formed in the lower region of the front panel 30.

In Figur 2 und 3 sind ferner vier winkelförmige Formelemente 42 gezeigt, die z.B. als einteilige Schmiedeteile geformt sind. Nachstehend werden nur die beiden unteren Elemente 42 mit Bezugszeichen versehen. Die oberen sind identisch aufgebaut, was aber nicht obligatorisch ist. Jedes Element 42 weist zwei Schenkel 44, 46 auf, die annähernd im rechten Winkel zueinander stehen. Der erste Schenkel 44 weist einen Rollenbolzen 48 als Endabschnitt auf, dessen Achse annähernd parallel und im Abstand zur Erstreckung der Frontplatte 30 verläuft. Der Rollenbolzen 48 geht stufenförmig in den angrenzenden im Querschnitt kreisförmigen Abschnitt 50 über. Auf der dem Rollenbolzen 48 zugekehrten Seite geht der erste Schenkel 50 über eine Rundung 52 in den zweiten Schenkel 46 über. Auf der dem Rollenbolzen 48 abgewandten Seite weist der zweite Schenkel eine Schrägfläche 54 auf. Bei einem Paar benachbarter Winkelelemente 42 konvergieren die Schrägflächen 54 zur Frontplatte 30 hin. Der Endabschnitt des zweiten Schenkels 46 der Formelemente 42 ist als Klotz geformt, dessen Umfangsfläche zur Umfangsfläche der Ausnehmungen 38 bzw. 40 passend ist. Mit dem Klotz 56, der sich gegenüber dem angrenzenden Abschnitt des zweiten Schenkels 46 stufenförmig erweitert, kann das Formelement passend in die Ausnehmung 38 bzw. 40 eingesetzt werden. Dies ist in Fig. 3 gezeigt.In FIG. 2 and 3 Furthermore, four angular shaped elements 42 are shown, which are formed, for example, as one-piece forgings. Hereinafter, only the two lower elements 42 are provided with reference numerals. The upper ones are identical, but this is not obligatory. Each element 42 has two legs 44, 46 which are approximately at right angles to each other. The first leg 44 has a roller pin 48 as an end portion, whose axis is approximately parallel and in the Distance from the extension of the front panel 30 extends. The roller pin 48 is stepped in the adjacent circular cross-section portion 50 via. On the side facing the roller pin 48, the first leg 50 passes over a curve 52 in the second leg 46. On the side facing away from the roller pin 48, the second leg has an inclined surface 54. In a pair of adjacent angle members 42, the inclined surfaces 54 converge toward the front panel 30. The end portion of the second leg 46 of the mold members 42 is formed as a pad, the peripheral surface of the circumferential surface of the recesses 38 and 40 is suitable. With the block 56, which widens stepwise relative to the adjacent portion of the second leg 46, the mold element can be suitably inserted into the recess 38 and 40, respectively. This is in Fig. 3 shown.

Um den Klotz 52 herum wird dann an der zugekehrten Fläche der Frontplatte 30 die Schweißnaht gelegt, was in Figur 3 nicht dargestellt ist.Around the block 52 is then placed on the facing surface of the front panel 30, the weld, which in FIG. 3 not shown.

Wie erkennbar, setzt sich der in den Figuren 2 und 3 dargestellte Schlitten aus zwei Einzelteilen zusammen, wobei ein Einzelteil, nämlich die Formelemente 50, vierfach ausgeführt sind. Das Ansetzen der Elemente 42 mit dem Klotz in den Ausnehmungen 34 bis 40 und das anschließende Verschweißen kann mit einer relativ einfach gestalteten Schweißvorrichtung durchgeführt werden. Danach sind die Rollenbolzen 48 in präziser Lage und Ausrichtung an der Frontplatte 30 angebracht.As can be seen, is the in the Figures 2 and 3 illustrated carriage of two individual parts together, with an item, namely the mold elements 50, are four times executed. The attachment of the elements 42 with the block in the recesses 34 to 40 and the subsequent welding can be carried out with a relatively simple design welding device. Thereafter, the roller pins 48 are mounted in precise position and orientation on the front panel 30.

Die Formelemente 42 können identisch sein. Für ein besseres Abrollen im Mastprofil haben die Rollenbolzen 48 oben und unten eine unterschiedliche Neigung. Die oberen haben z.B. eine Neigung von 2,5° von der Lastgabel fort und die unteren eine Neigung von z.B. 2,5° zur Gabel hin. Erzielt wird die Neigung durch unterschiedliche Rollenbolzen 48 oder durch eine unterschiedliche Neigung der Formelemente 42 gegenüber der Frontplatte 30.The mold elements 42 may be identical. For a better rolling in the mast profile, the roller pins 48 have a different inclination at the top and bottom. For example, the upper ones have an inclination of 2.5 ° away from the forks and the lower ones have an inclination of eg 2.5 ° towards the fork. The inclination is achieved by different roller bolts 48 or by a different inclination of the mold elements 42 relative to the front panel 30th

Wie ersichtlich, kann statt eines Winkelelements mit ausgeprägten Schenkeln ein klotzartiges Gebilde vorgesehen werden, von dem ein erster Abschnitt den Rollenbolzen hält und ein zweiter dazu senkrechter Abschnitt mit der Frontplatte verschweißbar ist, wobei der Rollenbolzen einen Abstand vom zweiten Abschnitt bzw. seinen zu verschweißenden Teil annähernd parallel zur Frontplatte hat. Die Ausformung eines solchen Elements zwischen Rollenbolzen und zu verbindenden Teil ist frei nach Festigkeitskriterien auslegbar. Sie erfordert jedoch einen höheren Materialeinsatz.As can be seen, instead of an angle element with pronounced limbs, a block-like structure can be provided, of which a first section holds the roller bolt and a second section perpendicular thereto can be welded to the front panel, wherein the roller bolt is spaced from the second section or its part to be welded has approximately parallel to the front panel. The formation of such an element between roller bolt and part to be connected is freely interpretable according to strength criteria. However, it requires a higher material usage.
