Aus der
Die Lastaufnahmeelemente können in ihrer Lastaufnahmeposition alternativ auch durch Steckbolzen gesichert werden. Eine solche Ausführungsform weist den Nachteil auf, dass die Steckbolzen selbst eine zusätzliche Sicherung gegen selbständiges Lösen erfordern und während der Veränderung der Position der Lastgabel solche Steckbolzen abhanden kommen können.The load-bearing elements can alternatively be secured in their load-receiving position by plug-in pins. Such an embodiment has the disadvantage that the locking pins themselves require an additional safeguard against self-loosening and during the change of the position of the load fork such locking pins can be lost.
Aus der
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lastaufnahme zu schaffen, welche ermöglicht, dass eine einfache und schnelle Veränderung einer gesicherten Lastaufnahmeposition des Lastaufnahmeelementes zum Querträger ermöglicht ist.The invention is therefore an object of the invention to provide a load bearing, which allows a simple and rapid change of a secured load-receiving position of the load-bearing element is made possible to the cross member.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen sind in den weiteren Ansprüchen angegeben.This object is achieved by the characterizing features of claim 1. Further advantageous embodiments and further developments are specified in the further claims.
Durch eine mit einer Abhebesicherung begrenzte Schwenkbewegung des Lastaufnahmeelementes zum Querträger ist ermöglicht, dass werkzeuglos das Lastaufnahmeelement aus und in eine gesicherte Lastaufnahmeposition überführbar ist. Dadurch ist eine schnelle Einstellung einer gewünschten Position des Lastaufnahmeelementes am Querträger ermöglicht. Nachdem das Lastaufnahmeelement durch die Schwenkbewegung aus seiner gesicherten Lastaufnahmeposition frei kommt, kann das Lastaufnahmeelement längs des Querträgers in seiner Position verändert werden. Nach Erreichen der gewünschten Position wird das Lastaufnahmeelement durch eine Umkehrung der Schwenkbewegung in eine gesicherte Lastaufnahmeposition übergeführt. Die Zurhilfenahme von Werkzeugen ist nicht erforderlich. Darüber hinaus ist eine zusätzliche Montage und Demontage von Steck- und/oder Sicherungselementen nicht erforderlich, die bei unsachgemäßer Handhabung eine ordnungsgemäße Sicherung der Lastaufnahmeposition nicht ermöglicht.By limited with a lift-off pivotal movement of the load-bearing element to the cross member is made possible that without tools, the load-receiving element from and into a secure load-receiving position can be transferred. This allows rapid adjustment of a desired position of the load-bearing element on the cross member. After the load-receiving element is released by the pivoting movement from its secure load-receiving position, the load-receiving element along the cross member can be changed in position. After reaching the desired position, the load-receiving element is converted by a reversal of the pivoting movement in a secure load-receiving position. The aid of tools is not required. In addition, an additional assembly and disassembly of plug and / or fuse elements is not required, which does not allow proper handling of the load-receiving position in case of improper handling.
Dabei ist vorgesehen, dass das Lastaufnahmemittel und der Querträger jeweils zumindest ein Halteelement aufweisen, welches in einer gesicherten Lastaufnahmeposition formschlüssig ineinander greifen. Die Halteelemente sind fest an dem Lastaufnahmeelement und dem Querträger angeordnet und somit unverlierbar. Durch das formschlüssige Ineinandergreifen wird ein einfaches Lösen und beim Zusammenführen eine Ausrichtung in eine vorgesehene Lastaufnahmeposition ermöglicht, so dass eine definierte Lage von dem Lastaufnahmeelement zum Querträger eingenommen wird. Durch ein solches formschlüssiges Ineinandergreifen wird zumindest ein seitliches Verschieben des Lastaufnahmeelementes gesichert. Dies weist insbesondere bei einer Lastaufnahme mit gabelförmig ausgebildeten Radgreifelementen den Vorteil auf, dass zwei an einem Rad angreifende Radgreifelemente ihren Abstand zueinander nicht vergrößern und sicher an dem Rad angreifen.It is provided that the load-receiving means and the cross member each have at least one holding element, which engage in a secure load-receiving position in a form-fitting manner. The holding elements are fixedly arranged on the load-receiving element and the cross member and thus captive. Due to the positive engagement, a simple release and when merging an alignment in a provided load-receiving position is made possible, so that a defined position is taken from the load-receiving element to the cross member. By such a positive engagement at least a lateral displacement of the load-receiving element is secured. This has the advantage, in particular in the case of a load bearing with fork-shaped wheel gripping elements, that two wheel gripping elements acting on a wheel do not increase their distance from one another and engage securely on the wheel.
Durch die Abhebesicherung ist ein Abheben des Abstützabschnittes am Lastaufnahmeelement von einem Lagesicherungsbereich des Querträgers derart gesichert und begrenzt, dass das Halteelement aus der U-förmigen Ausnehmung freikommt und das Lastaufnahmeelement entlang des Querträgers verschiebbar ist und ein weiteres Abheben des Abstützabschnittes verhindert ist. Ein kurzer Schenkel der L-förmig ausgebildeten Abhebesicherung hintergreift den Querträger, wobei der Abstand des L-förmigen hintergreifenden Abschnitts der Abhebesicherung und einer Stirnseite des Halteelementes am Lastaufnahmeelement in einem Abstand zueinander angeordnet sind, der zumindest der Dicke des vorzugsweise als Platte ausgebildeten Querträgers entspricht und nur geringfügig größer ausgebildet ist, damit eine einfache Verschiebung ohne Verhakung ermöglicht wird.By lift-off lifting a Abstützabschnittes on the load-receiving element of a position securing portion of the cross member is secured and limited such that the holding element is released from the U-shaped recess and the load-receiving element along the cross member is displaceable and a further lifting of the support section is prevented. A short leg of the L-shaped anti-lifting device engages behind the cross member, wherein the distance of the L-shaped engaging portion behind the anti-lifting device and an end face of the retaining element on the load-receiving element are arranged at a distance from each other, which corresponds at least to the thickness of the preferably formed as a plate cross member and is only slightly larger, so that a simple shift without entanglement is made possible.
Darüber hinaus ist ein Abstand zwischen der Abhebesicherung zum unteren Rand des Querträgers kleiner als eine Eingriffstiefe des Einhängebereiches ausgebildet, der am oberen Rand des Querträgers angreift. Dadurch wird beim Anheben des Lastaufnahmeelementes zur Entriegelung der Lastsicherungsposition ein Aushängen des Einhängebereichs am oberen Rand des Querträgers beziehungsweise des Tragbereiches des Querträgers verhindert.In addition, a distance between the anti-lift device to the lower edge of the cross member is formed smaller than an engagement depth of the Einhängebereiches, which engages the upper edge of the cross member. As a result, when the load-bearing element is lifted to release the load-securing position, the hanging-in area at the upper edge of the cross member or the support area of the cross member is prevented from being hung.
Bevorzugt ist vorgesehen, dass das Halteelement des Querträgers als eine randoffene und U-förmige Ausnehmung ausgebildet ist, in welche ein als Nocken ausgebildetes Halteelement des Lastaufnahmeelementes eingreift. Dadurch ist eine einfache und kostensparende Herstellung ermöglicht. Gleichzeitig sind einfache geometrische Verhältnisse gegeben, die eine schnelle Einnahme und ein schnelles Lösen des Lastaufnahmeelementes in und aus der Lastaufnahmeposition ermöglichen.It is preferably provided that the retaining element of the cross member is formed as an open-edged and U-shaped recess, in which engages formed as a cam holding member of the load-receiving element. This allows a simple and cost-saving production possible. At the same time simple geometric conditions are given, which allow a quick receipt and a quick release of the load-receiving element in and out of the load-receiving position.
Alternativ kann vorgesehen sein, dass anstelle der U-förmigen Ausnehmungen runde Bohrungen im Querträger vorgesehen sind, in die ein als konischer Zapfen ausgebildetes Halteelement, das am Lastaufnahmeelement vorgesehen ist, eingreift.Alternatively, it can be provided that, instead of the U-shaped recesses, round bores are provided in the cross member into which a holding element designed as a conical pin, which is provided on the load receiving element, engages.
Eine vorteilhafte Ausgestaltung der Halteelemente des Trägers sieht vor, dass die U-förmigen Ausnehmungen an einem unteren horizontal verlaufenden Abschnitt des Querträgers vorgesehen sind und einen Lagesicherungsbereich bilden. Die U-förmigen Ausnehmungen sind bevorzugt in regelmäßigen Abständen zueinander angeordnet, so dass eine rasterförmige Einstellung des Abstandes von zwei oder mehreren Lastaufnahmeelementen zueinander am Querträger ermöglicht ist.An advantageous embodiment of the holding elements of the carrier provides that the U-shaped recesses are provided on a lower horizontally extending portion of the cross member and form a position securing area. The U-shaped recesses are preferably arranged at regular intervals from each other, so that a grid-shaped Setting the distance of two or more load-bearing elements to each other on the cross member is made possible.
Die als Nocken ausgebildeten Halteelemente am Lastaufnahmeelement weisen bevorzugt Seitenflächen auf, die parallel zu den langen Schenkeln der U-förmigen Ausnehmungen ausgerichtet und zur Anlage daran ausgebildet sind. Dadurch wird ermöglicht, dass Querkräfte bei Belastung der Lastaufnahmeelemente sicher aufgenommen werden können und eine Verschiebung der Lastaufnahmeelemente im Betrieb verhindert ist.The retaining elements formed as cams on the load-receiving element preferably have side surfaces which are aligned parallel to the long legs of the U-shaped recesses and formed for abutment thereon. This makes it possible that lateral forces can be safely absorbed under load of the load-bearing elements and a displacement of the load-bearing elements is prevented during operation.
Das Lastaufnahmeelement greift an einem oberen Tragbereich des Querträgers mit einem Einhängebereich an, der ermöglicht, dass gegenüber liegend ein dem Lagesicherungsbereich zugeordneter Abstützabschnitt schwenkbar zum Querträger vorgesehen ist. Dadurch ist eine Schwenkachse für das Lastaufnahmeelementes am Tragbereich gebildet. Durch geringfügiges Anheben eines freien Endes am Lastaufnahmeelement beziehungsweise eines freien Endes an einer Lastgabel wird die Lastaufnahmeposition entriegelt oder kommt aus der Lastaufnahmeposition frei und ein Verschieben des Lastaufnahmeelementes längs zum Querträger ist ermöglicht. Nachdem die gewünschte Position des Lastaufnahmeelementes zum Querträger eingestellt ist, kann durch Absenken des Lastaufnahmeelementes aufgrund des Eigengewichtes eine gesicherte Lastaufnahmeposition wieder eingenommen werden. Aufgrund dieser Anordnung ist eine selbstsichernde Lastaufnahmeposition gegeben, so dass ohne zusätzliche Hilfsmittel die gesicherte Lage aufrecht erhalten bleibt.The load-receiving element engages an upper support region of the cross member with a hooking region, which enables a support portion assigned to the position-securing region to be provided opposite to the cross-member opposite to it. As a result, a pivot axis for the load-receiving element is formed on the support area. By slightly raising a free end on the load-receiving element or a free end on a fork, the load receiving position is unlocked or released from the load receiving position and a displacement of the load-receiving element along the cross member is possible. After the desired position of the load-receiving element is set to the cross member, by lowering the load-receiving element due to its own weight a secure load receiving position can be taken again. Due to this arrangement, a self-locking load receiving position is given, so that the secured position is maintained without additional aids.
Des Weiteren ist vorteilhafterweise vorgesehen, dass das Halteelement des Lastaufnahmeelementes gegenüber dem Abstützabschnitt in Richtung auf den Lagesicherungsbereich hervorsteht. Dadurch ist ein sicherer Eingriff am Querträger gegeben. Bevorzugt steht das Halteelement um die Dicke des insbesondere plattenförmigen Querträgers hervor, so dass zwischen dem nockenförmigen Halteelement und der U-förmigen Ausrichtung eine flächenförmige Anlage bei auftretenden Querkräften gegeben ist.Furthermore, it is advantageously provided that the holding element of the load-receiving element projects with respect to the support section in the direction of the position-securing area. As a result, a secure engagement is given to the cross member. Preferably, the holding element protrudes by the thickness of the particular plate-shaped cross member, so that between the cam-shaped holding element and the U-shaped orientation is given a sheet-like contact with occurring transverse forces.
Die Abhebesicherung weist vorteilhafterweise eine L-förmige Gestalt auf und ist spiegelbildlich zum Einhängebereich des Lastaufnahmeelementes ausgerichtet. Dadurch ist ermöglicht, dass der Querträger am Tragbereich und Lagesicherungsbereich sicher gegen Lösen von Querträger umgriffen ist und eine Verschlebbarkeit des Lastaufnahmeelementes längs zum Querträger erhalten bleibt.The lift-off advantageously has an L-shaped configuration and is mirror-inverted aligned to Einhängebereich the load-bearing element. This makes it possible that the cross member on the support area and position securing area is securely gripped against loosening of cross member and a Verschlebbarkeit the load-bearing element is maintained along the cross member.
Eine weitere Teilereduzierung zur Ausgestaltung einer Lastaufnahme ist vorzugsweise dadurch gegeben, dass das Halteelement und die Abhebesicherung einteilig ausgebildet sind. Durch diese einteilige Ausgestaltung kann der Herstellungsprozess für die Abhebesicherung und das Halteelement von zwei auf ein Teil reduziert werden. Darüber hinaus ist eine einfache und schnelle Befestigung ermöglicht.A further partial reduction for the design of a load bearing is preferably given by the fact that the holding element and the anti-lift device are integrally formed. Through this one-piece design, the manufacturing process for the lift-off and the retaining element can be reduced from two to one part. In addition, a simple and fast attachment is possible.
Bevorzugt ist vorgesehen, dass die Schwenkbewegung zum werkzeuglosen Überführen der Lastaufnahme aus einer gesicherten Position in eine ungesicherte Position und umgekehrt um eine Schwenkachse erfolgt, die durch den Einhängebereich des Lastaufnahmeelementes am Tragbereich des Querträgers gebildet ist, wobei die Schwenkachse parallel zum Tragbereich verläuft beziehungsweise in dessen Ebene liegt. Dadurch kann durch ein einfaches Anheben an der freien Spitze des Lastaufnahmeelementes eine Entriegelung erfolgen.It is preferably provided that the pivoting movement for tool-free transfer of the load receiving from a secured position in an unsecured position and vice versa about a pivot axis, which is formed by the Einhängebereich of the load-receiving element on the support portion of the cross member, wherein the pivot axis is parallel to the support portion or in the Level lies. This can be done by simply lifting the free tip of the load-receiving element unlocking.
Die Schwenkbewegung des Lastaufnahmeelementes zum Überführen in eine ungesicherte Lastaufnahmeposition zum Verschieben des Lastaufnahmeelementes entlang der Querstrebe liegt bevorzugt in einem Bereich zwischen 0,5° und 20°. Dadurch kann bereits ein geringes Anheben genügen, damit das Lastaufnahmeelement aus der gesicherten Position freikommt. Aufgrund des L-förmig ausgebildeten Lastaufnahmeelementes wird eine Hebelwirkung erzeugt, die eine Bedienung beziehungsweise ein Anheben erleichtert.The pivoting movement of the load-receiving element for transferring into an unsecured load-receiving position for displacing the load-receiving element along the transverse strut is preferably in a range between 0.5 ° and 20 °. As a result, even a slight lifting can be sufficient for the load-receiving element to be released from the secured position. Due to the L-shaped load-receiving element, a lever effect is generated which facilitates operation or lifting.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass der Querträger am jeweils äußeren Ende des Tragbereiches eine lösbare Verriegelung aufweist. Dies kann beispielsweise eine Schraub- oder Klemmverbindung sein. Nach dem Lösen dieser Verriegelung kann das Lastaufnahmeelement vollständig vom Querträger entnommen werden. Im Übrigen ist das Lastaufnahmeelement bei Vorhandensein der Verriegelung zum Querträger gesichert.According to a further advantageous embodiment of the invention it is provided that the cross member has a releasable locking at the respective outer end of the support area. This can be, for example, a screw or clamp connection. After releasing this lock, the load-bearing element can be completely removed from the cross member. Incidentally, the load-receiving element is secured in the presence of the lock to the cross member.
Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass zwei mit Lastaufnahmegabeln ausgebildete Lastaufnahmeelemente an dem Querträger vorgesehen sind, deren Abstand auf eine Radgröße einstellbar ist. Dadurch ist die Hubvorrichtung als mobile Hebeeinrichtung zusammen mit weiteren Hubvorrichtungen zum Anheben von mehrachsigen Fahrzeugen ausgebildet.According to a preferred embodiment of the invention it is provided that two trained with load-receiving forks load-receiving elements are provided on the cross member whose distance is adjustable to a wheel size. Thus, the lifting device is designed as a mobile lifting device together with other lifting devices for lifting multi-axle vehicles.
Die Lastaufnahmegabeln sind bevorzugt als rechtes und linkes Lastaufnahmeelement ausgebildet und weisen jeweils aufeinander zugerichtete Aufnahmeflächen auf. Dadurch kann eine Zentrierung des Rades oder weiterer Gegenständen zur Lastaufnahme ermöglicht werden.The load-bearing forks are preferably designed as right and left load-bearing element and each directed toward each other Recording surfaces on. As a result, a centering of the wheel or other objects for load bearing can be made possible.
Bevorzugt ist vorgesehen, dass die Aufnahmefläche der Lastaufnahmegabeln Bohrungen aufweist. Dies ermöglicht einen verbesserten Angriff an dem Rad. Zusätzlich kann eine Verringerung des Eigengewichtes der Lastaufnahmeelemente erzielt werden. Alternativ kann die Lastaufnahmefläche auch Profilierungen aufweisen.It is preferably provided that the receiving surface of the load-carrying forks has bores. This allows an improved attack on the wheel. In addition, a reduction in the dead weight of the load-bearing elements can be achieved. Alternatively, the load-bearing surface may also have profilings.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass das Lastaufnahmeelement ein linkes und rechtes plattenförmiges Halteprofil aufweist, an welchem jeweils ein Einhängebereich zum Angriff an dem Tragbereich des Querträgers vorgesehen ist. Aufgrund der Ausbildung der plattenförmigen Halteprofile kann der Einhängebereich durch eine einfache Stanz- oder Laserbearbeitung kostengünstig hergestellt werden. Durch die mit Abstand zueinander angeordneten linken und rechten Halteprofile ist eine sichere Auflage und verkippungssteife Anordnung des Lastaufnahmeelementes gegeben. Die Verkippungssteifigkeit wird darüber hinaus durch das am unteren Ende der Querstrebe eingreifende Halteelement zur Sicherung des Lastaufnahmeelementes ermöglicht.According to a further advantageous embodiment of the invention it is provided that the load-receiving element has a left and right plate-shaped retaining profile, on each of which a Einhängebereich is provided for engagement on the support region of the cross member. Due to the design of the plate-shaped retaining profiles of the hanging area can be produced inexpensively by a simple punching or laser machining. By spaced apart left and right retaining profiles a secure support and tilting arrangement of the load-bearing element is given. The Verkippungssteifigkeit is also made possible by the engaging at the lower end of the cross member retaining element for securing the load-receiving element.
Des Weiteren ist bevorzugt vorgesehen, dass das linke und rechte Halteprofil zumindest durch eine Querstrebe und eine Aufstandsfläche sowie insbesondere durch ein Distanzelement zueinander beabstandet sind. Dadurch kann eine einfache als auch steife Tragkonstruktion ausgebildet werden, die aus einzelnen Blechteilen hergestellt ist. Solche Blechteile können als Stanz- oder Laserbearbeitungsteile hergestellt sein. Dadurch wird eine Leichtbauweise erzielt.Furthermore, it is preferably provided that the left and right retaining profile at least by a transverse strut and a footprint and in particular by a spacer element are spaced from each other. Thereby, a simple and rigid support structure can be formed, which is made of individual sheet metal parts. Such sheet metal parts can be produced as stamping or laser machining parts. As a result, a lightweight construction is achieved.
Des Weiteren ist bevorzugt vorgesehen, dass die Aufstandsfläche als ein Stanz-Biegeteil ausgebildet ist, welches eine Aufnahmefläche und eine dazu abgewickelten Distanzabschnitt aufweist. Dadurch wird die Anzahl der Bauteile für das Lastaufnahmeelement weiter reduziert. Darüber hinaus kann die Steifigkeit erhöht sein. Durch die Verringerung der Bauteile kann auch eine kostengünstigere Montage ermöglicht sein.Furthermore, it is preferably provided that the contact surface is formed as a stamped and bent part, which has a receiving surface and a distance portion unwound therefrom. As a result, the number of components for the load-receiving element is further reduced. In addition, the stiffness can be increased. By reducing the components can also be a cheaper installation possible.
Des Weiteren ist bevorzugt vorgesehen, dass ein in vertikaler Richtung weisender und eine Last zugesandter Abschnitt des linken und rechten Halteprofiles des Lastaufnahmeelementes sowie insbesondere der Distanzabschnitt der Aufstandsfläche zur Hubvorrichtung geneigt sind und in einem Winkel größer als 90° zur Auflagefläche angeordnet sind. Diese Anordnung ermöglicht, dass eine Beschädigung der Last, insbesondere einer Radnabe beim Untergreifen der Räder, verhindert wird. Es wird somit ein größerer Freiraum zur Aufnahme der Last geschaffen als bei einer vertikal nach oben weisenden Ausrichtung.Furthermore, it is preferably provided that a section of the left and right holding profile of the load-receiving element pointing in the vertical direction and in particular the distance section of the contact surface to the lifting device are inclined and are arranged at an angle greater than 90 ° to the support surface. This arrangement makes it possible to prevent damage to the load, in particular a wheel hub, when the wheels engage under the wheel. It is thus created a greater clearance for receiving the load as in a vertically upward orientation.
Des Weiteren ist bevorzugt vorgesehen, dass das Lastaufnahmeelement durch die Halteprofile, die Querstrebe und die Aufstandsfläche in einer offenen Bauweise mit Freiräumen zueinander angeordnet sind. Diese offene Bauweise ermöglicht eine Gewichtseinsparung sowie eine einfache Herstellung. Darüber hinaus kann durch die offene Bauweise eine Feuerverzinkung vorgesehen werden, ohne dass zusätzliche Durchbrechungen oder Ausnehmungen in das Lastaufnahmeelement einzubringen sind.Furthermore, it is preferably provided that the load-receiving element are arranged by the holding profiles, the cross member and the footprint in an open design with free spaces to each other. This open design allows for weight savings and ease of manufacture. In addition, a hot dip galvanizing can be provided by the open design, without additional openings or recesses are to be introduced into the load-receiving element.
