Definitions
- the following application relates to an industrial truck with a mounting plate and an attachment attached thereto by at least one fastener, wherein a mounting surface facing the mounting plate of the attachment with an attachment pointing out mounting surface of the mounting plate is in touching contact.
- At least one intermediate element may be provided between the mounting plate and the attachment, in which case a bearing surface of the attachment pointing towards the mounting plate is in touching contact with a first contact surface of an intermediate element facing the attachment and one being an attachment facing mounting surface of the mounting plate is in touching contact with a second to the mounting plate facing contact surface of an intermediate element.
- Such trucks with the features of the preamble of claims 1 and 2 are, for example US 3 424 328 known.
- the devices commonly referred to as attachments may be, for example, a side push frame, a telescopic table, a staple fork and the like.
- the mounting plate is a universally designed mounting plate, which is designed to accommodate different attachments.
- the mounting plate is a type of standardized coupling point for coupling industrial truck bodies with attachments.
- the attachment of a truck Since the attachment of a truck must be designed both for receiving a large force and for accurate positioning, the attachment of the attachment to the mounting plate is of particular importance.
- the attachment must be sufficiently strong and rigid so that it can accurately position the attachment and / or its subassemblies even at high loads received by the truck allowed relative to the truck base body. Therefore attachments are often bolted to the mounting plate by applying high tightening torques.
- an attachment disk firmly connected to the attachment is frequently pressed flat against the mounting plate under the action of the attachment means.
- the associated with the truck mounting plate and / or attached to the attachment plant plate are not ideal dimensionally accurate and / or not ideal position, so that it is in the attachment of the attachment to the mounting plate to deformation and consequent tension on the attachment and the mounting plate can come.
- These tensioning forces which may occur on the attachment and on the mounting plate may interfere with the structures associated with the respective component: mounting plate and locating plate, i. Truck body and attachment, weight.
- the solution according to the invention allows a compensation movement of the components: attachment and mounting plate, relative to each other, so that even when applying a high or even very high fastening force deformation of the components: attachment and mounting plate occurs to a lesser extent than in the prior art, which in the Result leads to reduced stress forces.
- This reduces the overall load on the structures associated with the aforementioned components and increases their service life. With the reduced tension also less noise occurs at the mounting location.
- first and the second contact surface may be provided on one and the same intermediate element or on different intermediate elements.
- the mounting plate can be made in one piece or multiple parts. Different parts of the mounting plate can be arranged on different sections of the truck.
- the convexly curved portion of the at least one surface partially cylindrical, that is formed curved around an axis.
- the convexly curved section is curved around two mutually orthogonal axes, so that a sliding, tilting or rolling movement about two mutually orthogonal axes is possible between the attachment and the mounting surface.
- the convexly curved portion may be formed, for example, barrel-shaped or ellipsoidal.
- the mentioned examples of configurations of the convexly curved section have a different radius of curvature for each axis of curvature, so that a preferred direction of compensating movements can be present.
- the convexly curved portion of the at least one surface is formed in the form of a spherical cap. If a spherical cap-shaped surface abuts another surface, it is possible under essentially the same circumstances for any tilting movement of the spherical cap to take place about a tilting axis, which lies in a plane which is spanned by the above-mentioned, mutually orthogonal axes.
- the portion of a mating surface with which the convexly curved portion of the aforesaid surface is in touching contact may be flat in a simple case.
- a compensatory rolling movement of the components: attachment and mounting plate relative to each other with a suitable design of the convex curved portion in all directions possible but due to low Berhausenrome vom between a convex surface portion and a flat surface portion a very high surface pressure at the Bernton.stelle between the convex curved surface portion and a flat mating surface portion occur.
- This can lead to high material loads.
- the portion of the mating surface is also convexly curved, which may possibly facilitate compensating movements in certain particularly loaded directions, but this can also lead to a high surface pressure.
- the portion of a mating surface, with which the convexly curved portion of the at least one surface is in touching contact is formed concavely curved.
- the lowest possible surface pressure in the section of the contact contact is obtained if the concavely curved section of the mating surface is adapted to the convexly curved section of the at least one surface such that the convexly curved section is in surface contact contact with the concavely curved section.
- a kind of "ball joint" can be formed using the above-mentioned spherical cap on the convexly curved portion, in which the concave curved portion of the mating surface is a part-spherical ball socket conforming to the spherical cap.
- the convex curved surface portion and the concave curved mating surface portion can then slide relative to each other, wherein this sliding leads to a tilting of the components relative to each other, on which the surface portion and the mating surface portion are formed.
- the mounting plate, as well as the mounting device often represent bulky components with relatively large dimensions. For this reason, it may be less advantageous from a manufacturing point of view to provide the convexly curved portion of these. With less processing, the convex curved portion can be advantageously provided on an intermediate element.
- the convexly curved portion having intermediate element is arranged in the truck, that the convexly curved portion is provided on the first contact surface of the stationary contact element with the contact surface in contact.
- the mounting plate which should be designed to accommodate a variety of different attachments, are produced with very little processing effort.
- a concave recess can be provided in a simple manner, such as by milling, in which the convexly curved portion of the intermediate element comes to rest.
- the intermediate elements can be spacing or shims, which are inserted for fine adjustment of a desired position of the attachment relative to the mounting plate between the attachment and the mounting plate.
- Fig. 1 is an inventive truck generally designated 10. From the truck body 11, a driver's seat carrier 12 are shown with a mounting plate 14 welded thereto. On the mounting plate 14, a side push frame 16 is fastened by screws 18.
- the screws 18 enforce this investment slices 20, which are firmly welded to the side push frame 16 as an attachment.
- the screws 18 are screwed into threaded bores 22 of the mounting plate 14.
- side push frame 16 is hooked with likewise hooked thereto hook elements 24 at the upper edge 14 a of the mounting plate 14 and in the embodiment shown optionally secured by screws 26 in addition to the mounting plate 14.
- the intermediate elements comprise three spacer or fitting rings 28 and a Kugelkalottenrace 30. Both the spacers 28, as well as the Kugelkalottenrace 30 are penetrated by their associated screws 18, so that one of the screws 18 on the contact plates 20 applied fastening force over the entire circumference the intermediate elements 28 and 30 is received by these.
- Fig. 2 shows a schematic cross section through the mounting plate 14 and the side push frame 16th
- the mounting plate 14 is welded to two supports 12 a and 12 b of the driver station carrier 12 by welds 32.
- the partially cut side push frame 16 is hooked by means of the hook elements 24.
- the side facing frame 16 facing mounting surface 14b of the mounting plate 14 is formed substantially flat to mount a variety of different attachments to the mounting plate, so that one and the same driver position carrier 12 can be used depending on the attachment for different functions.
- An abutment surface 20a of the abutment disc 20 is formed with a concave recess 34, in which the Kugelkalottenrace 30 projects with the first spherical cap-shaped contact surface 30a. More specifically, the recess 34 is partially spherical, so that the spherical cap-shaped first contact surface 30a of the spherical cap 30 abuts flat against the contact surface 20a of the contact disk 20.
- the spherical cap 30 and the washer 20 thus form a ball joint, in which the contact disk 20 can be pivoted about two lying in the plane of the mounting plate 14, mutually orthogonal axes X and Z in sliding movement along the Kugelkalottentignsynthesis 30 a.

Description
Die folgende Anmeldung betrifft ein Flurförderzeug mit einer Montageplatte und einem an dieser durch wenigstens ein Befestigungsmittel befestigten Anbaugerät, wobei eine zur Montageplatte hin weisende Anlagefläche des Anbaugeräts mit einer zum Anbaugerät hin weisenden Montagefläche der Montageplatte in Berührkontakt ist.The following application relates to an industrial truck with a mounting plate and an attachment attached thereto by at least one fastener, wherein a mounting surface facing the mounting plate of the attachment with an attachment pointing out mounting surface of the mounting plate is in touching contact.
In einer alternativen Modifikation dieses Flurförderzeug kann zwischen der Montageplatte und dem Anbaugerät wenigstens ein Zwischenelement vorgesehen sein, wobei in diesem Falle eine zur Montageplatte hin weisende Anlagefläche des Anbaugeräts mit einer ersten zum Anbaugerät hin weisenden Kontaktfläche eines Zwischenelements in in Berührkontakt ist und wobei eine zum Anbaugerät hin weisende Montagefläche der Montageplatte in Berührkontakt mit einer zweiten zur Montageplatte hin weisenden Kontaktfläche eines Zwischenelements ist.In an alternative modification of this truck, at least one intermediate element may be provided between the mounting plate and the attachment, in which case a bearing surface of the attachment pointing towards the mounting plate is in touching contact with a first contact surface of an intermediate element facing the attachment and one being an attachment facing mounting surface of the mounting plate is in touching contact with a second to the mounting plate facing contact surface of an intermediate element.
Derartige Flurförderzeuge mit den Merkmalen der Oberbegriffs der Ansprüche 1 und 2 sind z.B. aus
Da das Anbaugerät eines Flurförderzeugs sowohl zur Aufnahme einer großen Kraft als auch zur genauen Positionierung ausgebildet sein muss, kommt der Anbringung des Anbaugeräts an der Montageplatte besondere Bedeutung zu. Die Anbringung muss ausreichend stabil und steif sein, so dass sie auch bei hohen am Flurförderzeug aufgenommenen Lasten eine genaue Positionierung des Anbaugeräts und/oder seiner Unterbaugruppen relativ zum Flurförderzeug-Grundkörper erlaubt. Daher werden Anbaugeräte häufig unter Aufbringung hoher Anzugsdrehmomente an die Montageplatte angeschraubt. Um Relativbewegungen zwischen der Montageplatte und dem Anbringungsgerät zu vermeiden, wird häufig eine mit dem Anbaugerät fest verbundene Anlagescheibe unter Einwirkung des Befestigungsmittels flächig an die Montageplatte angedrückt.Since the attachment of a truck must be designed both for receiving a large force and for accurate positioning, the attachment of the attachment to the mounting plate is of particular importance. The attachment must be sufficiently strong and rigid so that it can accurately position the attachment and / or its subassemblies even at high loads received by the truck allowed relative to the truck base body. Therefore attachments are often bolted to the mounting plate by applying high tightening torques. In order to avoid relative movements between the mounting plate and the attachment device, an attachment disk firmly connected to the attachment is frequently pressed flat against the mounting plate under the action of the attachment means.
In vielen Fällen sind die mit dem Flurförderzeug verbundene Montageplatte oder/und die mit dem Anbaugerät verbundene Anlagescheibe nicht ideal formgenau oder/und nicht ideal lagegenau, so dass es bei der Befestigung des Anbaugeräts an der Montageplatte zu Verformungen und daraus resultierenden Verspannungen am Anbaugerät und an der Montageplatte kommen kann. Diese am Anbaugerät und an der Montageplatte möglicherweise auftretenden Verspannungskräfte können die mit dem jeweiligen Bauteil: Montageplatte und Anlagescheibe, verbundenen Strukturen, d.h. Flurförderzeug-Grundkörper und Anbaugerät, belasten.In many cases, the associated with the truck mounting plate and / or attached to the attachment plant plate are not ideal dimensionally accurate and / or not ideal position, so that it is in the attachment of the attachment to the mounting plate to deformation and consequent tension on the attachment and the mounting plate can come. These tensioning forces which may occur on the attachment and on the mounting plate may interfere with the structures associated with the respective component: mounting plate and locating plate, i. Truck body and attachment, weight.
Durch die verhältnismäßig großen Verspannungen kann es im Betrieb der Flurförderzeuge weiter zu einer unerwünschten Geräuschbildung kommen, welche sich etwa als "Knarzen" äußert. Bereits das Geräusch an sich ist störend, es kann jedoch auch aufgrund der Geräuschentwicklung irrtümlich auf einen Fehler oder einen Schaden des Flurförderzeugs geschlossen werden und das Flurförderzeug einer Inspektion unterzogen werden, während der es einem Betrieb nicht zur Verfügung steht.Due to the relatively large tension, it can continue to come in operation of the trucks on to an undesirable noise, which manifests itself as "creaking". Even the noise itself is disturbing, but it can also be due to the noise by mistake on a fault or damage to the truck to be closed and the truck to be subjected to an inspection during which it is not available to a company.
Es ist daher Aufgabe der vorliegenden Erfindung, eine technische Lehre anzugeben, mit welcher ein Anbaugerät an einer Montagefläche eines Flurförderzeug-Grundkörpers unter Vermeidung befestigungsbedingter Verspannungskräfte angebracht werden kann. Weiterhin soll die Geräuschentwicklung an den oben genannten Flurförderzeugen minimiert werden.It is therefore an object of the present invention to provide a technical teaching, with which an attachment can be attached to a mounting surface of a truck base body while avoiding fastening-related bracing forces. Furthermore, the noise on the above-mentioned trucks should be minimized.
Die genannte Aufgabe wird durch ein Flurförderzeug gemäß Anspruch 1 bzw. 2gelöst.The above object is achieved by an industrial truck according to
Die erfindungsgemäße Lösung ermöglicht eine Ausgleichsbewegung der Bauteile: Anbaugerät und Montageplatte, relativ zueinander, so dass auch bei Aufbringen einer hohen oder sogar sehr hohen Befestigungskraft eine Verformung der Bauteile: Anbaugerät und Montageplatte, in geringerem Maße als im Stand der Technik auftritt, was in der Folge zu verringerten Verspannungskräften führt. Dadurch wird die Gesamtbelastung der mit den zuvor genannten Bauteilen verbundenen Strukturen reduziert und deren Lebensdauer erhöht. Mit den verringerten Verspannungen treten auch weniger Geräusche an der Montagestelle auf.The solution according to the invention allows a compensation movement of the components: attachment and mounting plate, relative to each other, so that even when applying a high or even very high fastening force deformation of the components: attachment and mounting plate occurs to a lesser extent than in the prior art, which in the Result leads to reduced stress forces. This reduces the overall load on the structures associated with the aforementioned components and increases their service life. With the reduced tension also less noise occurs at the mounting location.
Durch die konvexe Ausbildung wenigstens einer der Flächen im Abschnitt des Berührkontakts wird zumindest eine geringfügige Gleit- oder Abwälzbewegung der zuvor genannten Bauteile relativ zueinander ermöglicht. Dadurch kann das Anbaugerät bei der Montage ausgerichtet werden.Due to the convex formation of at least one of the surfaces in the section of the contact contact, at least a slight sliding or rolling movement of the abovementioned components relative to one another is made possible. This allows the attachment to be aligned during assembly.
Es sei darauf hingewiesen, dass die erste und die zweite Kontaktfläche an ein und demselben Zwischenelement oder aber an verschiedenen Zwischenelementen vorgesehen sein können. Es sei weiter ausdrücklich darauf hingewiesen, dass die Montageplatte einteilig oder mehrteilig ausgeführt sein kann. Unterschiedliche Teile der Montageplatte können an unterschiedlichen Abschnitten des Flurförderzeugs angeordnet sein.It should be noted that the first and the second contact surface may be provided on one and the same intermediate element or on different intermediate elements. It should further be noted that the mounting plate can be made in one piece or multiple parts. Different parts of the mounting plate can be arranged on different sections of the truck.
Grundsätzlich ist es möglich, dass der konvex gekrümmte Abschnitt der wenigstens einen Fläche teilzylinderförmig, d.h. um eine Achse gekrümmt ausgebildet ist. Bevorzugt ist der konvex gekrümmte Abschnitt jedoch um zwei zueinander orthogonale Achsen gekrümmt ausgebildet, so dass zwischen Anbaugerät und Montagefläche eine Gleit-, Kipp- oder Wälzbewegung um zwei zueinander orthogonale Achsen möglich ist. Hierzu kann der konvex gekrümmte Abschnitt beispielsweise tonnenförmig oder ellipsoid ausgebildet sein. Die genannten Beispiele für Ausbildungen des konvex gekrümmten Abschnitts weisen für jede Krümmungsachse einen anderen Krümmungsradius auf, so dass eine Vorzugsrichtung von Ausgleichsbewegungen vorliegen kann.Basically, it is possible that the convexly curved portion of the at least one surface partially cylindrical, that is formed curved around an axis. Preferably, however, the convexly curved section is curved around two mutually orthogonal axes, so that a sliding, tilting or rolling movement about two mutually orthogonal axes is possible between the attachment and the mounting surface. For this purpose, the convexly curved portion may be formed, for example, barrel-shaped or ellipsoidal. The mentioned examples of configurations of the convexly curved section have a different radius of curvature for each axis of curvature, so that a preferred direction of compensating movements can be present.
Bevorzugt ist daher der konvex gekrümmte Abschnitt der wenigstens einen Fläche in Form einer Kugelkalotte ausgebildet. Liegt eine kugelkalottenförmige Fläche an einer anderen Fläche an, so kann unter stets im Wesentlichen gleichen Umständen eine beliebige Kippbewegung der Kugelkalotte um eine Kippachse erfolgen, welche in einer Ebene liegt, die von den zuvor genannten, zueinander orthogonalen Achsen aufgespannt wird.Preferably, therefore, the convexly curved portion of the at least one surface is formed in the form of a spherical cap. If a spherical cap-shaped surface abuts another surface, it is possible under essentially the same circumstances for any tilting movement of the spherical cap to take place about a tilting axis, which lies in a plane which is spanned by the above-mentioned, mutually orthogonal axes.
Der Abschnitt einer Gegenfläche, mit welchem der konvex gekrümmte Abschnitt der zuvor genannten Fläche in Berührkontakt ist, kann in einem einfachen Fall eben ausgebildet sein. In diesem Falle ist zwar eine ausgleichende Wälzbewegung der Bauteile: Anbaugerät und Montageplatte, relativ zueinander bei geeigneter Ausbildung des konvex gekrümmten Abschnitts in allen Raumrichtungen möglich, jedoch kann aufgrund geringer Berührkontaktflächen zwischen einem konvexen Flächenabschnitt und einem ebenen Flächenabschnitt eine sehr hohe Flächenpressung an der Berührkontaktstelle zwischen dem konvex gekrümmten Flächenabschnitt und einem ebenen Gegenflächenabschnitt auftreten. Dies kann zu hohen Materialbelastungen führen. Ebenso ist es grundsätzlich möglich, dass der Abschnitt der Gegenfläche ebenfalls konvex gekrümmt ist, was möglicherweise Ausgleichsbewegungen in bestimmten besonders belasteten Richtungen erleichtern kann, was jedoch ebenfalls zu einer hohen Flächenpressung führen kann.The portion of a mating surface with which the convexly curved portion of the aforesaid surface is in touching contact may be flat in a simple case. In this case, although a compensatory rolling movement of the components: attachment and mounting plate relative to each other with a suitable design of the convex curved portion in all directions possible, but due to low Berührkontaktflächen between a convex surface portion and a flat surface portion a very high surface pressure at the Berührkontaktstelle between the convex curved surface portion and a flat mating surface portion occur. This can lead to high material loads. Likewise, it is basically possible that the portion of the mating surface is also convexly curved, which may possibly facilitate compensating movements in certain particularly loaded directions, but this can also lead to a high surface pressure.
Zur Vermeidung einer derart hohen Flächenpressung kann vorgesehen sein, dass der Abschnitt einer Gegenfläche, mit welchem der konvex gekrümmte Abschnitt der wenigstens einen Fläche in Berührkontakt ist, konkav gekrümmt ausgebildet ist. Dabei erhält man eine möglichst geringe Flächenpressung im Abschnitt des Berührkontakts dann, wenn der konkav gekrümmte Abschnitt der Gegenfläche derart an den konvex gekrümmten Abschnitt der wenigstens einen Fläche angepasst ist, dass der konvex gekrümmte Abschnitt in flächigem Berührkontakt mit dem konkav gekrümmten Abschnitt ist. Dabei kann unter Verwendung der oben genannten Kugelkalotte am konvex gekrümmten Abschnitt eine Art "Kugelgelenk" gebildet werden, bei welchem der konkav gekrümmte Abschnitt der Gegenfläche eine sich an die Kugelkalotte anschmiegende teilsphärische Kugelpfanne darstellt. Der konvex gekrümmte Flächenabschnitt und der konkav gekrümmte Gegenflächenabschnitt können dann relativ zueinander gleiten, wobei dieses Gleiten zu einer Verkippung der Bauteile relativ zueinander führt, an welchen der Flächenabschnitt und der Gegenflächenabschnitt ausgebildet sind.To avoid such a high surface pressure can be provided that the portion of a mating surface, with which the convexly curved portion of the at least one surface is in touching contact, is formed concavely curved. In this case, the lowest possible surface pressure in the section of the contact contact is obtained if the concavely curved section of the mating surface is adapted to the convexly curved section of the at least one surface such that the convexly curved section is in surface contact contact with the concavely curved section. In this case, a kind of "ball joint" can be formed using the above-mentioned spherical cap on the convexly curved portion, in which the concave curved portion of the mating surface is a part-spherical ball socket conforming to the spherical cap. The convex curved surface portion and the concave curved mating surface portion can then slide relative to each other, wherein this sliding leads to a tilting of the components relative to each other, on which the surface portion and the mating surface portion are formed.
Eine besonders günstige, weil symmetrische Belastung der wenigstens einen Fläche mit konvexer Krümmung kann dadurch erhalten werden, dass der konvex gekrümmte Abschnitt der wenigstens einen Fläche von dem Befestigungsmittel durchsetzt ist. Zusätzlich oder alternativ kann auch der konkav gekrümmte Abschnitt der wenigstens einen Gegenfläche von dem Befestigungsmittel durchsetzt sein, um eine symmetrische Krafteinleitung um die Befestigungsstelle herum bereitzustellen.A particularly favorable, because symmetrical loading of the at least one surface with convex curvature can be obtained by the fact that the convexly curved portion of the at least one surface is penetrated by the fastening means. Additionally or alternatively, the concavely curved portion of the at least one mating surface may be penetrated by the fastening means to provide a symmetrical force introduction around the attachment point.
Die Montageplatte, wie auch das Anbringungsgerät stellen häufig sperrige Bauteile mit verhältnismäßig großen Abmessungen dar. Aus diesem Grunde kann es aus fertigungstechnischer Sicht weniger vorteilhaft sein, den konvex gekrümmten Abschnitt an diesen vorzusehen. Mit geringerem Bearbeitungsaufwand kann der konvex gekrümmte Abschnitt vorteilhafter an einem Zwischenelement vorgesehen werden.The mounting plate, as well as the mounting device often represent bulky components with relatively large dimensions. For this reason, it may be less advantageous from a manufacturing point of view to provide the convexly curved portion of these. With less processing, the convex curved portion can be advantageously provided on an intermediate element.
Dabei ist weiter von Vorteil, wenn das den konvex gekrümmten Abschnitt aufweisende Zwischenelement derart im Flurförderzeug angeordnet ist, dass der konvex gekrümmte Abschnitt an der ersten Kontaktfläche des mit der Anlagefläche in Berührkontakt stehenden Zwischenelements vorgesehen ist. In diesem Falle kann die Montageplatte, welche zur Aufnahme einer Vielzahl unterschiedlicher Anbaugeräte ausgebildet sein soll, mit sehr geringem Bearbeitungsaufwand erzeugt werden. Am Anbaugerät, welchem stets ein Einsatzzweck zuordenbar ist, kann dagegen in einfacher Weise eine konkave Ausnehmung vorgesehen werden, etwa durch Fräsen, in welcher der konvex gekrümmte Abschnitt des Zwischenelements zur Anlage kommt.It is further advantageous if the convexly curved portion having intermediate element is arranged in the truck, that the convexly curved portion is provided on the first contact surface of the stationary contact element with the contact surface in contact. In this case, the mounting plate, which should be designed to accommodate a variety of different attachments, are produced with very little processing effort. On the attachment, which always a purpose is assigned, however, a concave recess can be provided in a simple manner, such as by milling, in which the convexly curved portion of the intermediate element comes to rest.
Nachzutragen ist, dass es sich bei den Zwischenelementen um Distanz- oder Passscheiben handeln kann, welche zur Feineinstellung einer gewünschten Lage des Anbaugeräts relativ zur Montageplatte zwischen Anbaugerät und Montageplatte eingelegt werden.It should be added that the intermediate elements can be spacing or shims, which are inserted for fine adjustment of a desired position of the attachment relative to the mounting plate between the attachment and the mounting plate.
