Description

Die Erfindung bezieht sich auf ein Flurförderzeug mit Radarmen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a truck with radar arms according to the preamble of patent claim 1.

Bei einer bestimmten Kategorie von Flurförderzeugen ist seitlich am Rahmen der Flurförderzeuge ein Paar Radarme angebracht, die am vorderen Ende Lasträder lagern. Die Radarme dienen dazu, das Fahrzeug im Bereich des Lastteils abzustützen, d.h. zu verhindern, dass das Fahrzeug nach vom kippt.In a certain category of industrial trucks, a pair of wheel arms are mounted laterally on the frame of the industrial trucks, bearing load wheels at the front end. The wheel arms serve to support the vehicle in the region of the load part, i. to prevent the vehicle from tipping over.

Bei derartigen Flurförderzeugen ist manchmal notwendig, eine größere Spurbreite auf der Lastseite des Fahrzeugs zu haben. Wenn z.B. in einer höheren Regalebene eine Palette entnommen werden soll, ebenerdig jedoch die Radarme keinen Raum finden, in den sie einfahren können, etwa wegen einer quer stehenden Palette, wäre es wünschenswert, eine größere Spurbreite für die Radarme zu haben. Es ist bekannt, für spezielle Einsatzfälle eine jeweilige Spurbreite für die Radarme vorzusehen. Dadurch ergeben sich jedoch für die Herstellung sowie für die Konstruktion und den Versand veränderte Anforderungen im Vergleich zu Standardfahrzeugen des gleichen Typs. Solche Anforderungen sind ein Materialaufwand, größerer Herstellungsaufwand sowie eine aufwändigere Montage.In such trucks is sometimes necessary to have a larger track width on the load side of the vehicle. If e.g. In a higher racking level, a pallet is to be removed, but at ground level, the wheel arms find no room in which they can retract, for example because of a transverse pallet, it would be desirable to have a wider track width for the wheel arms. It is known to provide a specific track width for the wheel arms for special applications. As a result, however, the manufacturing, construction and shipping requirements are changed as compared to standard vehicles of the same type. Such requirements are a cost of materials, greater manufacturing costs and a more complex installation.

Es sind bereits unterschiedliche Möglichkeiten bekannt geworden, die Spurweite von Radarmen dadurch zu verändern, dass die Radarme mit unterschiedlichen Abständen an den Rahmen angeschweißt werden. Dies hat jedoch den Nachteil, dass die Spurweite nachträglich nicht mehr verändert werden kann und dass wegen der Breite in der Produktion und im Versand mit wesentlich unhandlicheren Fahrzeugrahmen umgegangen werden muss. Außerdem sind angeschweißte Radarme bei einem Fehler nicht austauschbar, sodass der ganze Fahrzeugrahmen betroffen ist.There are already different ways known to change the track width of radar arms by the fact that the wheel arms are welded to the frame at different distances. However, this has the disadvantage that the track can not be changed later and that must be handled because of the breadth in production and shipping with much unwieldy vehicle frame. In addition, welded-wheel arms are not interchangeable in case of failure, so that the whole vehicle frame is affected.

Eine andere bekannte Möglichkeit ist, die Schnittstelle des Radarms verstellbar auszuformen, je nach gewünschter Fahrzeug- bzw. Spurweite. Dies hat jedoch den Nachteil, dass auch bei schmaleren Fahrzeugausführungen das Material im Fahrzeug für die breiteste Variante des Fahrzeugstyps vorhanden sein muss. Außerdem ist das Einstellen der exakten Fahrzeugbreite mit einem zusätzlichen Aufwand verbunden.Another known possibility is to adjust the interface of the radar adjustable, depending on the desired vehicle or track. However, this has the disadvantage that even with narrower vehicle designs, the material in the vehicle for the widest variant of the vehicle type must be present. In addition, the setting of the exact vehicle width is associated with additional effort.

Schließlich kann für unterschiedliche Spurweiten eines Flurförderzeugs ein eigener Radarmtyp vorgesehen werden. Jeder dieser Radarmtypen kann an einer Schnittstelle am Fahrzeugrahmen bzw. Hubgerüst montiert werden. Dies ist etwa in US 6,138,796 offenbart. Nachteilig bei dieser Ausführung ist jedoch, dass für jede weitere geforderte Spurweite zwei Radarme benötigt werden. Dies erzeugt eine hohe Varianz bei der Materialbevorratung.Finally, a separate Radarmtyp can be provided for different gauges of a truck. Each of these radar types can be mounted on an interface on the vehicle frame or mast. This is about in US 6,138,796 disclosed. A disadvantage of this design, however, is that two more wheel arms are required for each additional required track. This creates a high variance in material storage.

Der Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug zu schaffen, das mit geringem Material- und Montageaufwand auf unterschiedliche Spurweiten der Radarme eingestellt werden kann.The invention has for its object to provide a truck that can be adjusted with low material and assembly costs to different gauges of the wheel arms.

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

Bei dem erfindungsgemäßen Flurförderzeug ist auf jede Außenseite des Rahmens eine Rahmenplatte fest angebracht. Die Rahmenplatte weist Löcher auf mit einem vorgegebenen ersten Lochbild. Mit den Radarmen sind Radarmplatten verbunden, welche Durchbohrungen aufweist. Die Durchbohrungen ergeben ein zweites Lochbild. Ferner ist mindestens ein Paar Adapterblöcke mit zweiten Durchbohrungen vorgesehen, die ein drittes Lochbild ergeben. Erstes, zweites und drittes Lochbild sind identisch. Radarm- und Rahmenplatte sowie Adapterblöcke liegen über erste bis vierte Anlagenflächen gegeneinander. Die Adapterblöcke haben eine vorgegebene Länge. Schließlich sind bei der Erfindung zwei Satz Bolzen vorgesehen, wobei jeder Satz Bolzen unterschiedlicher Länge aufweist. Der erste Satz dient zur Verbindung von Rahmen- und Radarmplatte unmittelbar, während der zweite Satz zur Verbindung von Radarmplatte und Rahmenplatte mit einem Adapterblock dazwischen dient.In the truck according to the invention, a frame plate is fixedly mounted on each outer side of the frame. The frame plate has holes with a predetermined first hole pattern. Radar plates are connected to the Radarmen, which has through holes. The holes result in a second hole pattern. Furthermore, at least one pair Adapter blocks provided with second holes, which give a third hole pattern. First, second and third hole patterns are identical. Radarm- and frame plate and adapter blocks are about first to fourth contact surfaces against each other. The adapter blocks have a predetermined length. Finally, in the invention, two sets of bolts are provided, each set having bolts of different lengths. The first set serves to connect the frame and Radarmplatten directly, while the second set is used to connect Radarmplatte and frame plate with an adapter block in between.

Statt der Radarmplatte kann auch ein geeigneter, entsprechend dicker Abschnitt der Rahmenwand vorgesehen sein zur Anbringung der Radarme.Instead of the Radarmplatte can also be provided a suitable, correspondingly thicker portion of the frame wall for attachment of the wheel arms.

Die Bolzen können Spannbolzen sein, die an der Rahmenplatte ein Widerlager finden, während sie am äußeren Ende z.B. ein Gewinde haben, auf das eine Mutter aufgeschraubt werden kann. Vorzugsweise sind jedoch Gewindebolzen vorgesehen, die in Gewindebohrungen der Rahmenplatten einschraubbar sind, um Radarmplatte ohne oder mit Adapterblock an der Rahmenplatte zu befestigen.The bolts may be tension bolts which find an abutment on the frame plate while at the outer end e.g. have a thread on which a nut can be screwed on. Preferably, however, threaded bolts are provided which can be screwed into threaded bores of the frame plates to attach Radarmplatte without or with adapter block to the frame plate.

Bei der Erfindung ist pro Seite des Flurförderzeugs eine einzige Schnittstelle vorgesehen. Ferner gibt es bei der Erfindung nur einen einzigen Radarmtyp, welcher seinerseits eine Schnittstelle besitzt, über welche man den Radarm befestigen kann. Um verschiedene Spurweiten zu erzeugen, wird der Adapterblock zwischen der Schnittstelle am Rahmen und der Schnittstelle am Radarm montiert. Die Adapterblöcke mehrerer Paare können eine unterschiedliche Länge haben, je nach gewünschter Spurweite. Es ist jedoch auch möglich, eine Mehrzahl von z.B. kürzeren Adapterblöcken vorzusehen, wobei sich die Spurweite aus der Anzahl der zusammengesetzten Adapterblöcke ergibt. Bei der Erfindung ist daher nicht erforderlich, eigene Radarmtypen für unterschiedliche Spurweiten vorzuhalten, sondern jeweils nur die Adapterblöcke für die Anordnung zwischen Radarmplatte und Rahmenplatte.In the invention, a single interface is provided per side of the truck. Further, in the invention, there is only one type of radar arm, which in turn has an interface over which one can attach the radar arm. To create different gauges, the adapter block is mounted between the interface on the frame and the interface on the wheel arm. The adapter blocks of several pairs may have a different length, depending on the desired gauge. However, it is also possible to provide a plurality of, for example, shorter adapter blocks, where the gauge is the number of composite adapter blocks. In the invention, therefore, is not necessary to hold own Radarmtypen for different gauges, but only the adapter blocks for the arrangement between Radarmplatte and frame plate.

Radarm- und Rahmenplatten und Adapterblöcke haben - wie erwähnt - Anlageflächen, die in einer Ausgestaltung der Erfindung plan sein können. Sie können jedoch auch einen Formschluss ermöglichen, der zu einer Momentenübertragung beitragen kann. Der Formschluss kann zum Beispiel durch eine Bajonettverbindung hergestellt werden oder durch Nut- oder Federverbindung, durch eine gezahnte Verbindung oder durch Eingreifen von Vorsprüngen in Ausnehmungen oder dergleichen.Radarm- and frame plates and adapter blocks have - as mentioned - contact surfaces, which may be flat in one embodiment of the invention. However, they can also allow a form fit, which can contribute to a moment transfer. The positive connection can be produced for example by a bayonet connection or by tongue and groove connection, by a toothed connection or by engagement of projections in recesses or the like.

Entgegen fest angeschweißten Radarmen können diese bei der Erfindung nachträglich mittels Adapterstücken auf gewünschte Spurweite gebracht werden. Bei einem Defekt braucht lediglich das entsprechende Einzelteil ausgetauscht zu werden. Entgegen frei verstellbaren Radarmen wird bei der Erfindung immer nur die Menge an Material verbaut, die für die Bildung einer gewünschten Spurweite erforderlich ist. Auch entfällt eine aufwändige Einstellung der Spurweite und der Ausrichtung, da die Adapterblöcke in ihrer Breite und Position zur Schnittstelle fest sein können. Es ist jedoch gemäß einer weiteren Ausgestaltung der Erfmdung auch möglich, die Adapterblöcke teleskopisch in ihrer Länge veränderbar zu machen. In diesem Falle müssen Mittel vorgesehen werden, die Adapterblöcke in ihrer jeweils eingestellten Länge festzulegen.Contrary firmly welded Radarmen these can be brought later in the invention by means of adapters to desired track width. In case of a defect, only the corresponding item needs to be replaced. Contrary to freely adjustable radar arms in the invention, only the amount of material is required, which is required for the formation of a desired track. Also, eliminates a costly adjustment of the track and the orientation, since the adapter blocks can be fixed in their width and position to the interface. However, according to a further embodiment of the invention, it is also possible to make the adapter blocks telescopically variable in their length. In this case, means must be provided to set the adapter blocks in their set length.

Bei der Erfindung entfällt das Vorhalten von unterschiedlichen Radarmen, die als größtes Teil der Konstruktion stets gleichbleiben. Die kleinste Spur kann dadurch erzeugt werden, dass die Radarme unmittelbar am Rahmen befestigt werden, d.h. ohne Adapterblöcke.In the invention eliminates the provision of different radar arms, which always remain the same as the largest part of the construction. The smallest trace can be created by attaching the wheel arms directly to the frame, i. without adapter blocks.

Da die Adapterblöcke auf beiden Seiten des Fahrzeugs gleich sein können, braucht jeweils nur eine Ausführung vorgesehen zu werden.Since the adapter blocks can be the same on both sides of the vehicle, only one design needs to be provided at a time.

Wie schon erwähnt, können die Sätze von Adapterblöcken Paare unterschiedlicher Länge oder gleicher Länge aufweisen. Die Radarmplatten sind vorzugsweise am hinteren Ende der Radarme seitlich angeschweißt.As already mentioned, the sets of adapter blocks can have pairs of different lengths or the same length. The Radarmplatten are preferably welded laterally at the rear end of the wheel arms.

Nach einer weiteren Ausgestaltung der Erfindung können mindestens zwei Satz von Scherbolzen vorgesehen sein, die von zweiten Bohrungen der Radarmplatten, der Rahmenplatten und der Adapterblöcke passend aufnehmbar sind. Die Scherbolzen dienen zur verbesserten Übertragung des Moments von den Radarmen auf den Fahrzeugrahmen, nicht aber zur Befestigung der Radarme.According to a further embodiment of the invention, at least two sets of shear pins can be provided, which are receivable by second holes of the Radarmplatten, the frame plates and the adapter blocks fitting. The shear pins are used for improved transmission of torque from the wheel arms to the vehicle frame, but not for attachment of the wheel arms.

Radarmplatten und/oder Adapterblöcke können zweite Gewindebohrungen aufweisen zur Aufnahme von Abziehgewindestiften. Ein Abziehen ist dann unter Umständen erforderlich, wenn Scherbolzen eingesetzt werden. Diese sitzen unter Pressung in den Bohrungen, sodass für das Abziehen der Adapterblöcke bzw. der Radarmplatten eine entsprechende Kraft aufgewendet werden muss.Radarmplatten and / or adapter blocks may have second threaded holes for receiving Abziehgewindestiften. Pulling off may be required if shear bolts are used. These sit under pressure in the holes, so that for removing the adapter blocks or Radarmplatten a corresponding force must be expended.

Nach einer anderen Ausgestaltung der Erfindung können die Rahmenplatten eine mittige Ausnehmung aufweisen. Nach einer weiteren Ausgestaltung der Erfindung können die Adapterblöcke Hohlkörper sein. Die zu den Radarmplatten hin gerichtete Wandung der hohlen Adapterblöcke kann eine Ausnehmung aufweisen. Auf diese Weise kann zu den Gewindebohrungen für Abziehstifte ein besserer Zugang erhalten werden.According to another embodiment of the invention, the frame plates may have a central recess. According to a further embodiment of Invention, the adapter blocks may be hollow body. The wall of the hollow adapter blocks directed toward the radar plates may have a recess. In this way, a better access can be obtained to the tapping holes for Abziehstifte.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von Zeichnungen näher erläutert.

In Figur 1 und 2 ist ein Rahmen 10 eines nicht weiter dargestellten Flurförderzeugs gezeigt. Der Rahmen nimmt die Antriebsvorkehrungen für das Flurförderzeug auf sowie auch den nicht gezeigten Lastteil. Zu beiden Seiten des Rahmens sind jeweils Radarme angeordnet, wobei in den Figuren 1 und 2 nur ein Radarm 12 gezeigt ist. Derartige Radarme lagern am vorderen Ende ein Lastrad, das jedoch hier nicht dargestellt ist. Im Folgenden wird auch nur auf den Radarm 12 Bezug genommen, wobei sich von selbst versteht, dass der zweite nicht gezeigte Radarm komplimentär ausgebildet ist.In FIGS. 1 and 2 a frame 10 of a truck not shown is shown. The frame accommodates the drive arrangements for the truck as well as the load section, not shown. On both sides of the frame each wheel arms are arranged, wherein in the Figures 1 and 2 only one wheel arm 12 is shown. Such radar arms store at the front end a load wheel, which, however, is not shown here. In the following, reference will also be made only to the wheel arm 12, it being understood that the second wheel arm, not shown, is complementary.

Man erkennt ferner in den Figuren 1 und 2, dass der Radarm 12 am hinteren Ende eine Radarmplatte 14 aufweist, die durch seitliches Anschweißen an das Profil des Radarms 12 befestigt ist. Am Rahmen 10, d.h. an seitlichem Rahmenblech, ist im unteren Bereich eine Rahmenplatte 16 angeschweißt. Zwischen den Platten 14, 16 ist ein Adapterblock 18 angeordnet. In Figur 2 ist zu erkennen, wie diese Einzelteile miteinander verbunden sind. Die Abmessungen der Platten 14, 16 bzw. des Adapterblocks bestimmt den Abstand der Radarme voneinander.One recognizes further in the Figures 1 and 2 in that the wheel arm 12 has, at the rear end, a wheel arm plate 14 which is fastened by lateral welding to the profile of the wheel arm 12. On the frame 10, ie on lateral frame plate, a frame plate 16 is welded in the lower region. Between the plates 14, 16, an adapter block 18 is arranged. In FIG. 2 It can be seen how these individual parts are interconnected. The dimensions of the plates 14, 16 and the adapter block determines the distance of the wheel arms from each other.

In der Figur 3 ist zu erkennen, dass die Radarmplatte 14 erste Durchbohrungen 20 aufweist. Auf der dem Fahrzeugrahmen 10 zugewandten Seite sind zweite Bohrungen 22 vorgesehen, die jedoch nicht durchgehen. Schließlich sind im Durchmesser relativ kleine Durchbohrungen 24 vorgesehen, die ein Gewinde aufweisen (nicht gezeigt). Von den Bohrungen 20 und 22 sind jeweils vier vorhanden, während von den Durchbohrungen 24 jeweils zwei vorgesehen sind. Die Bohrungen 20 bis 24 weisen jeweils ein vorgegebenes Lochbild auf.In the FIG. 3 It can be seen that the Radarmplatte 14 has first holes 20. On the side facing the vehicle frame 10 second holes 22 are provided, which do not pass though. Finally, in diameter relatively small through holes 24 are provided which have a thread (not shown). Of the holes 20 and 22, four are present, while two of the through holes 24 are provided. The holes 20 to 24 each have a predetermined hole pattern.

In Figur 4 ist die Rahmenplatte 16 vergrößert herausgestellt. Sie weist erste Bohrungen 26 und zweite Bohrungen 28 auf, die jeweils ein vorgegebenes Lochbild ergeben. Zwischen den Bohrungen 26, 28 ist die Platte mit einer kreuzartigen Ausnehmung 30 versehen. Diese dient der Materialersparnis.In FIG. 4 the frame plate 16 is exposed enlarged. It has first holes 26 and second holes 28, each resulting in a given hole pattern. Between the holes 26, 28, the plate is provided with a cross-shaped recess 30. This serves to save material.

Wie zu erkennen, sind die einander zugekehrten Flächen der Radarmplatte 14 und der Rahmenplatte 16 plan.As can be seen, the facing surfaces of Radarmplatte 14 and the frame plate 16 are flat.

In Figur 5 ist vergrößert der Adapterblock 18 dargestellt. Er weist erste Bohrungen 34 auf und zweite Bohrungen 36, die jeweils ein bestimmtes Lochbild ergeben. Der Adapterblock 18 ist als Hohlkörper ausgeführt, wobei seine der Radarmplatte 14 zugekehrte Seite eine kreuzförmige Ausnehmung 38 aufweist. Die Rückwand ist mit im Durchmesser kleineren Gewindebohrungen 40 versehen. Man erkennt in Figur 5 auch, dass das Lochbild der Bohrungen 34, 36 zum Lochbild der Bohrungen 34, 36 auf der Rückseite bzw. auf der dem Rahmen 10 zugewandten Seite identisch ist.In FIG. 5 enlarged, the adapter block 18 is shown. He has first holes 34 and second holes 36, each giving a specific hole pattern. The adapter block 18 is designed as a hollow body, wherein its Radarmplatte 14 facing side has a cross-shaped recess 38. The rear wall is provided with smaller diameter threaded holes 40. One recognizes in FIG. 5 Also, that the hole pattern of the holes 34, 36 is identical to the hole pattern of the holes 34, 36 on the back or on the frame 10 side facing.

In Figur 6 ist ebenfalls ein Adapterblock 18a zu erkennen, der sich von dem nach Figur 5 nur durch seine geringere Länge unterscheidet. Das Lochbild der Durchbohrungen ist im Übrigen zu dem des Adapterblocks 18 identisch, sodass darauf nicht weiter eingegangen werden soll.In FIG. 6 is also an adapter block 18a can be seen, which differs from the FIG. 5 only distinguished by its shorter length. Incidentally, the hole pattern of the through holes is identical to that of the adapter block 18, so that it will not be discussed further.

In Figur 7 ist gezeigt, wie die in Figur 2 dargestellte Verbindung des Radarms mit dem Rahmen erfolgt. Man erkennt in Figur 7 vier identische Schraubenbolzen 42 mit endseitigem Kopf, denen jeweils eine Scheibe 44 zugeordnet ist. Die Schraubenbolzen werden in die Durchbohrungen 20 der Radarmplatte 14 gesteckt und durch die Durchbohrungen 34 des Adapterblocks 18 hindurchgesteckt und mit einem Gewindeabschnitt am freien Ende in die Gewindebohrungen 26 der Rahmenplatte 16 eingeschraubt. Auf diese Weise kann der Radarm 12 fest mit dem Rahmen 10 verbunden werden. Die Schraubenköpfe sind vorzugsweise in den Bohrungen 20 versenkt. Der Abstand des Radarms 12 von der Seite des Rahmens 10 bestimmt sich durch die Dicke der Platten 16, 14 und der Länge des Adapterblocks 18. Erste Spannhülsen 46 sitzen in den Bohrungen 28 der Rahmenplatte 16 und in den Bohrungen 36 des Adapterblocks 18. Zweite Spannhülsen 48 sitzen in den Bohrungen 36 des Adapterblocks 18 und den Bohrungen 22 der Radarmplatte 14. Die Spannhülsen 46, 48 dienen zur Aufnahme des Moments zwischen Radarm 12 und Rahmen 10. Sie sitzen unter Pressung in den zugehörigen Bohrungen, sodass mit Hilfe von nicht gezeigten Abziehstiften, welche in die Bohrungen 24 bzw. in die Bohrungen 40 (Figur 5) eingeschraubt werden, Adapterblock 18 bzw. Radarmplatte 14 von Adapterblock 18 getrennt werden kann.In FIG. 7 is shown as the in FIG. 2 shown connection of the Radarms done with the frame. One recognizes in FIG. 7 four identical bolts 42 with end-side head, each associated with a disc 44. The bolts are inserted into the through holes 20 of Radarmplatte 14 and inserted through the through holes 34 of the adapter block 18 and screwed with a threaded portion at the free end in the threaded holes 26 of the frame plate 16. In this way, the wheel arm 12 can be firmly connected to the frame 10. The screw heads are preferably countersunk in the bores 20. The distance of the Radarms 12 from the side of the frame 10 is determined by the thickness of the plates 16, 14 and the length of the Adapter sleeves 18. First clamping sleeves 46 are seated in the bores 28 of the frame plate 16 and in the bores 36 of the adapter block 18. Second clamping sleeves 48 are seated in the bores 36 of the adapter block 18 and the bores 22 of the radar plate 14. The clamping sleeves 46, 48 serve to receive The moment between the wheel arm 12 and the frame 10. They sit under pressure in the associated holes, so that with the aid of not shown Abziehstiften which in the holes 24 and in the bores 40 ( FIG. 5 ) can be screwed, adapter block 18 and Radarmplatte 14 of adapter block 18 can be separated.

In Figur 8 ist zu erkennen, wie die Spurweite von Radarmen 12 durch drei Adapterblöcke 18a, 18b, 18c verändert werden kann. Es versteht sich, dass die Adapterblöcke 18 bis 18c auch unterschiedliche Länge haben können bzw. relativ kurz sein können, um je nach Wunsche eine feine Abstufung vorzunehmen. Bezüglich des Aufbaus der Adapterblöcke 18b und 18c ist zu bemerken, dass er mit dem des Blocks 18 gleich ist. In Figur 8 sind die Verbindungsbolzen nicht gezeigt und auch nicht die Spannhülsen gemäß Figur 7.In FIG. 8 It can be seen how the track width of radar arms 12 can be changed by three adapter blocks 18a, 18b, 18c. It is understood that the adapter blocks 18 to 18c may also have different lengths or may be relatively short to make a fine gradation as desired. With regard to the structure of the adapter blocks 18b and 18c, it should be noted that it is the same as that of the block 18. In FIG. 8 the connecting bolts are not shown and not the clamping sleeves according to FIG. 7 ,
