Description

Die Erfindung betrifft ein Hochregalflurförderzeug mit einem Rahmen, der eine Befestigungsvorrichtung für ein Hubwerk und eine Schnittstelle zur Befestigung einer Laufradachse aufweist, wobei die Befestigungsvorrichtung für das Hubwerk eine Auflage zur Übertragung von vertikalen Kräften umfasst, wobei die Auflage im unteren Bereich des Rahmens angeordnet ist.The invention relates to a high-rack truck with a frame having a fastening device for a hoist and an interface for attachment of a wheel axle, wherein the fastening device for the hoist comprises a support for transmitting vertical forces, wherein the support is arranged in the lower region of the frame.

Hochregalflurförderzeuge wie z.B. Hochregalstapler oder Hochregalkommissionierer weisen ein Hubwerk und einen Rahmen auf, die während des Betriebs des Hochregalflurförderzeugs starr miteinander verbunden sind. Um diese starre Verbindung sicher zu gewährleisten, weist der Rahmen eine Befestigungsvorrichtung für das Hubwerk auf, die das Übertragen von Kräften und Momenten von dem Hubwerk auf den Rahmen ermöglicht. Gleichzeitig dient die Befestigungsvorrichtung dazu, die Position des Hubwerks relativ zu dem Rahmen zu justieren und damit mögliche Fertigungsungenauigkeiten des Rahmens auszugleichen.High rack trucks such as High rack stackers or high rack order pickers have a hoist and a frame which are rigidly connected together during operation of the high rack truck. To ensure this rigid connection safely, the frame has a fastening device for the hoist, which allows the transfer of forces and moments of the hoist on the frame. At the same time, the fastening device serves to adjust the position of the hoist relative to the frame and thus compensate for possible manufacturing inaccuracies of the frame.

Insbesondere die Gewichtskräfte des Hubwerks und der damit aufgenommenen Lasten werden von dem Rahmen über eine Laufradachse auf der Fahrbahn abgestützt. Zur Anbindung der Laufradachse an den Rahmen weist dieser eine Schnittstelle auf, an der die Laufradachse mit dem Rahmen verschweißt ist.In particular, the weight forces of the hoist and the loads absorbed by it are supported by the frame via an impeller axis on the road. To connect the impeller axis to the frame, this has an interface at which the impeller shaft is welded to the frame.

Bei bekannten Hochregalflurförderzeugen ist die Befestigungsvorrichtung für das Hubwerk sehr aufwändig ausgeführt und umfasst eine von der Laufradachse nach oben beabstandete gelenkige Auflage, über die die Gewichtskräfte des Hubwerks in den Rahmen eingeleitet werden. Der Kraftfluss von der gelenkigen Auflage zu der Laufradachse führt über zwei senkrechte Stützen, die jeweils auf einen waagrechten Träger des Rahmens aufgeschweißt sind.In known high-bay industrial trucks, the fastening device for the hoist is very complex and includes an upwardly spaced from the impeller axis hinged support over which the weight forces of the hoist are introduced into the frame. The power flow from the articulated support to the impeller axis via two vertical supports, which are each welded to a horizontal support of the frame.

Eine gattungsgemäße Anordnung ist aus der US 3 756 350 bekannt. Das darin gezeigte Hochregalflurförderzeug besitzt einen Rahmen mit horizontalen Radarmen, auf denen das Hubwerk aufsteht. Das Hubwerk ist dabei mit dem Rahmen starr verschraubt. Um eine exakt senkrechte Ausrichtung des Hubwerks zu gewährleisten, müssen der Rahmen und das Hubwerk mit sehr engen Fertigungstoleranzen hergestellt werden.A generic arrangement is known from US 3,756,350. The high-bay truck shown therein has a frame with horizontal arms on which the hoist stands up. The hoist is rigidly bolted to the frame. In order to ensure an exactly vertical alignment of the hoist, the frame and the hoist must be made with very tight manufacturing tolerances.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Hochregalflurförderzeug mit einer einfach aufgebauten Befestigungsvorrichtung für das Hubwerk zur Verfügung zu stellen, welche geringere Anforderungen an die Fertigungstoleranzen des Hubwerks und des Rahmens stellt.The present invention is based on the object to provide a high-bay truck with a simple structure mounting device for the hoist available, which makes lower demands on the manufacturing tolerances of the hoist and the frame.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Befestigungsvorrichtung eine Einstellvorrichtung für die Neigung des Hubwerks um eine horizontale Querachse des Flurförderzeugs aufweist. Mit der Einstellvorrichtung werden Fertigungstoleranzen ausgeglichen, die zu einer unerwünschten Neigung des Hubwerks nach vorne oder nach hinten führen würden.Die Anordnung der Auflage im unteren Bereich des Rahmens ermöglicht es, auf die im Stand der Technik zur Befestigung des Hubwerks üblichen senkrechten Stützen zu verzichten. Die Kräfte des Hubwerks können dadurch direkt in die tragenden waagrechten Teile des Rahmens eingeleitet werden. Der Kraftfluss führt auf kurzem Weg direkt von der Auflage des Hubwerks zu der Schnittstelle zur Befestigung der Laufradachse.This object is achieved in that the fastening device has an adjustment for the inclination of the hoist about a horizontal transverse axis of the truck. With the adjustment manufacturing tolerances are compensated, which would lead to an undesirable inclination of the hoist forward or backward. The arrangement of the support in the lower part of the frame makes it possible to dispense with the usual in the art for mounting the hoist vertical supports. The forces of the hoist can be introduced directly into the supporting horizontal parts of the frame. The power flow leads on a short path directly from the support of the hoist to the interface for attachment of the impeller axis.

Die vertikale Position der Auflage entspricht dabei im Wesentlichen der vertikalen Position der Schnittstelle zur Befestigung der Laufradachse. Auflage und Schnittstelle befinden sich damit auf gleicher Höhe.The vertical position of the support essentially corresponds to the vertical position of the interface for fastening the impeller axis. Edition and interface are thus at the same height.

Die Auflage und die Schnittstelle zur Befestigung der Laufradachse sind in Fahrzeuglängsrichtung unmittelbar benachbart. Das eingebaute Hubwerk schließt dabei direkt an die Laufradachse an.The support and the interface for fixing the impeller axis are immediately adjacent in the vehicle longitudinal direction. The built-in hoist connects directly to the impeller axis.

Die Einstellvorrichtung für die Neigung des Hubwerks weist mindestens zwei Einstellschrauben auf, mit denen die Position des Hubwerks gegenüber dem Rahmen einstellbar ist. Die Einstellschrauben sind von kostengünstigen Normschrauben gebildet, die mit einfachen Werkzeugen eine präzise Einstellung der Neigung des Hubwerks ermöglichen.The adjustment device for the inclination of the hoist has at least two adjusting screws, with which the position of the hoist is adjustable relative to the frame. The adjusting screws are made of inexpensive standard screws, which allow a simple adjustment of the inclination of the hoist with simple tools.

Mit besonderem Vorteil ist mindestens eine Einstellschraube als Zugschraube und mindestens eine Einstellschraube als Druckschraube ausgeführt und ist das Hubwerk mittels der Einstellschrauben gegenüber dem Rahmen verspannt. Bei der Zugschraube und der Druckschraube handelt es sich um Normschrauben, auf die das Hubwerk eine Zugkraft bzw. eine Druckkraft ausübt. Die Schraubenköpfe beider Einstellschrauben sind von derselben Seite des Hubwerks aus zugänglich. Die Einstellschrauben verspannen das Hubwerk gegenüber dem Rahmen und legen damit die Position des Hubwerks eindeutig fest.With particular advantage, at least one adjusting screw is designed as a tension screw and at least one adjusting screw as a pressure screw and the hoist is clamped by means of the adjusting screws relative to the frame. The lag screw and the pressure screw are standard screws on which the hoist exerts a tensile force or a compressive force. The screw heads of both adjustment screws are accessible from the same side of the hoist. The adjusting screws clamp the hoist against the frame and thus clearly determine the position of the hoist.

Die horizontale Querachse, um die das Hubwerk mittels der Einstellvorrichtung für die Neigung des Hubwerks neigbar ist, ist oberhalb der Einstellschrauben angeordnet. Im Bereich der Einstellschrauben kann das Hubwerk mittels der Einstellschrauben geringfügig nach vorne oder nach hinten verschoben werden, was eine Neigebewegung um die genannte horizontale Querachse bewirkt. Im Bereich der Querachse ist das Hubwerk derart mit dem Rahmen verbunden, dass eine translatorische Bewegung des Hubwerks in Längsrichtung des Hochregalflurförderzeugs ausgeschlossen ist.The horizontal transverse axis about which the hoist is tiltable by means of the adjustment of the inclination of the hoist is arranged above the adjusting screws. In the range of adjusting screws, the hoist can be moved slightly forward or backward by means of the adjusting screws, which causes a tilting movement about said horizontal transverse axis. In the area of the transverse axis, the hoist is connected to the frame such that a translational movement of the hoist in the longitudinal direction of the high-rack truck is excluded.

Vorzugsweise ist das Hubwerk im Bereich des Querachse in Fahrzeuglängsrichtung formschlüssig mit dem Rahmen verbunden. Die formschlüssige Verbindung stellt sicher, dass sich das Hubwerk im Bereich der Querachse auf keinen Fall von dem Rahmen löst und nach vorne oder hinten umkippt.Preferably, the hoist in the vehicle longitudinal direction is positively connected to the frame in the region of the transverse axis. The positive connection ensures that the hoist never detaches from the frame in the area of the transverse axis and tilts forward or backward.

Darüber hinaus ist im Bereich der Querachse mindestens eine Spannschraube vorgesehen, mit der das Hubwerk gegenüber dem Rahmen verspannt ist. Damit weist das Hubwerk gegenüber dem Rahmen im Bereich der Querachse kein Spiel auf.In addition, at least one clamping screw is provided in the region of the transverse axis with which the lifting mechanism is braced relative to the frame. Thus, the hoist with respect to the frame in the transverse axis on no play.

Die Befestigungsvorrichtung ist derart ausgeführt, dass die Neigung des Hubwerks um eine Fahrzeuglängsachse starr festgelegt ist. Eine Einstellmöglichkeit für die Neigung des Hubwerks in seitlicher Richtung ist damit nicht gegeben. Stattdessen wird bei der Herstellung der Rahmenteile insbesondere die Position der Auflage mit derart großer Genauigkeit festgelegt, dass ein Nachjustieren der seitlichen Neigung des Hubwerks nicht erforderlich ist.The fastening device is designed such that the inclination of the hoist is fixed rigidly about a vehicle longitudinal axis. An adjustment for the inclination of the hoist in the lateral direction is thus not given. Instead, in the manufacture of the frame parts in particular the position of the support is determined with such great accuracy that a readjustment of the lateral inclination of the lifting mechanism is not required.

Figur 1 zeigt einen Ausschnitt eines Rahmen eines Hochregalflurförderzeugs. Die tragenden Längsbauteile des Rahmens sind von zwei seitlichen Längsplatten 1 gebildet, die sich vom vorderen Ende des Rahmens, an dem sich die Schnittstelle 2 zur Befestigung einer Laufradachse befindet, bis zum dem nicht dargestellten hinteren Ende des Rahmens erstreckt. Bestandteil des Rahmens sind darüber hinaus eine untere Querstrebe 3, eine obere Querstrebe (Fig. 2, Pos. 4) sowie weitere, im hinteren Bereich des Rahmens angeordnete Querstreben 5, die die beiden Längsplatten 1 miteinander verbinden. Die Schnittstelle 2 zur Befestigung der nicht dargestellten Laufradachse ist von den Längsplatten 1 selbst und von zusätzlichen, an die Längsplatten 1 angeschweißten Verstärkungsblechen 6 gebildet.FIG. 1 shows a section of a frame of a high-rack industrial truck. The supporting longitudinal members of the frame are formed by two lateral longitudinal plates 1, which extends from the front end of the frame, where the interface 2 is for mounting an impeller axis, to the rear end of the frame, not shown. Part of the frame beyond a lower cross member 3, an upper cross member (Fig. 2, Pos. 4) and further, arranged in the rear region of the frame cross member 5, which connect the two longitudinal plates 1 together. The interface 2 for fastening the impeller axis, not shown, is formed by the longitudinal plates 1 itself and by additional, welded to the longitudinal plates 1 reinforcing plates 6.

Diese Verstärkungsbleche 6 bilden einen Teil der Befestigungsvorrichtung für das Hubwerk 7. Ebenfalls Teil der Befestigungsvorrichtung sind die Querstreben 3 und 4 sowie zwei Klötze 8, wobei an jeder Längsplatte jeweils ein Klotz 8 angeschweißt ist.These reinforcing plates 6 form part of the fastening device for the hoist 7. Also part of the fastening device are the cross braces 3 and 4 and two blocks 8, wherein a block 8 is welded to each longitudinal plate.

Anhand Figur 2, die eine Seitenansicht des Ausschnitts gemäß Figur 1 zeigt, ist der Aufbau der Befestigungsvorrichtung für das Hubwerk 7 im Einzelnen erläutert. Die dargestellte Vorrichtung ist jeweils einmal auf der linken und einmal auf der rechten Seite des Hochregalflurförderzeugs vorhanden. Ein Anbaublech 10, das Bestandteil des Hubwerks 7 ist, liegt mit der durch Striche gekennzeichneten unteren Stirnfläche auf dem Verstärkungsblech 6 auf, das damit eine Auflage zur Übertragung von vertikalen Kräften bildet. Mit einer Schraube 11 ist das Hubwerk 7 gegen ein Abheben nach oben gesichertWith reference to Figure 2, which shows a side view of the detail of Figure 1, the structure of the fastening device for the lifting mechanism 7 is explained in detail. The device shown is in each case once on the left and once on the right side of the high-bay truck available. An attachment plate 10, which is part of the lifting mechanism 7, lies with the lower end face indicated by dashes on the reinforcing plate 6, which thus forms a support for the transmission of vertical forces. With a screw 11, the lifting mechanism 7 is secured against lifting up

Im oberen Bereich der Befestigungsvorrichtung ist das Hubwerk 7 mittels eines Anbaublechs 12 an dem Klotz 8 eingehängt. Ein Kippen des Hubwerks 7 nach vorne oder nach hinten ist damit mittels Formschluss verhindert. Um während des Betriebs des Hochregalflurförderzeugs eine aufgrund der Spielpassung mögliche Relativbewegung zwischen dem Anbaublech 12 und dem Klotz 8 zu verhindern, ist das Anbaublech 12 mittels einer Spannschraube 13 zusätzlich zwischen der Querstrebe 4 und dem Klotz 8 verspannt.In the upper part of the fastening device, the hoist 7 is mounted by means of a mounting plate 12 to the block 8. A tilting of the hoist 7 forward or backward is thus prevented by positive locking. In order to prevent possible due to the clearance relative movement between the mounting plate 12 and the block 8 during operation of the high-rack truck, the mounting plate 12 is additionally clamped by a clamping screw 13 between the crossbar 4 and the block 8.

Die Einstellung der Neigung des Hubwerks 7 erfolgt mittels der Einstellschrauben 14 und 15. Mit diesen kann das Hubwerks 7 im unteren Bereich nach vorne und hinten verschoben werden, was ein Drehen des gesamten Hubwerks 7 um den Klotz 8 bewirkt. Die als Druckschraube ausgeführte Einstellschraube 15 bildet dabei einen Anschlag für ein an das untere Ende des Hubwerks 7 angeschweißtes Anbaublech 16 bezüglich einer Bewegung nach in der Zeichnung rechts. Hierbei ist die Einstellschraube 15 in ein Gewindeloch der Querstrebe 3 eingeschraubt und kann durch Drehen in Schraubenlängsrichtung verstellt werden. Die als Zugschraube ausgeführte Einstellschraube 14 stützt sich mit ihrem Schraubenkopf an der Querstrebe 3 ab und ist in eine Gewindebohrung im Anbaublech 16 eingeschraubt. Die als Zugschraube ausgeführte Einstellschraube 14 verspannt das Anbaublech 16 des Hubgerüsts 7 gegen die Druckschraube 15.The adjustment of the inclination of the lifting mechanism 7 by means of the adjusting screws 14 and 15. With these, the hoist 7 can be moved in the lower region forward and backward, causing a rotation of the entire hoist 7 to the block 8. The running as a pressure screw adjusting screw 15 forms a stop for a welded to the lower end of the lifting unit 7 mounting plate 16 with respect to a movement to the right in the drawing. Here, the adjusting screw 15 is screwed into a threaded hole of the crossbar 3 and can be adjusted by turning in the screw longitudinal direction. The adjustment screw 14 designed as a draw screw is supported with its screw head on the cross strut 3 and is screwed into a threaded bore in the mounting plate 16. The adjusting screw 14 designed as a tension screw clamps the mounting plate 16 of the mast 7 against the pressure screw 15.
