Description

Die Erfindung betrifft eine Hebevorrichtung zum Anheben von Lasten, insbesondere von Fahrzeugen oder dergleichen.The invention relates to a lifting device for lifting loads, in particular of vehicles or the like.

Aus der DE 20 2006 014 183 U1 ist eine Hebevorrichtung zum Anheben von Lasten, insbesondere von Fahrzeugen oder dergleichen, bekannt, welche als Fahrschienenhebebühne ausgebildet ist. Zwei parallel verlaufende Fahrschienen werden jeweils durch ein Hubelement auf und ab bewegt. Diese Hubelemente sind als Schere ausgebildet, welche zwei sich kreuzende Scherenhebel aufweist. Zur Auf- und Abbewegung der Fahrschiene ist ein Zylinder vorgesehen, der einerseits an der Fahrschiene und andererseits nach einem Kreuzungspunkt zwischen zwei Scherenhebeln angreift. In der Fahrschiene ist eine Antriebseinrichtung des hydraulischen Zylinders angeordnet, welche eine elektrische Hydraulikpumpe und eine Ventilsteuereinheit umfasst.From the DE 20 2006 014 183 U1 is a lifting device for lifting loads, in particular of vehicles or the like, known, which is designed as a travel lift. Two parallel running rails are each moved up and down by a lifting element. These lifting elements are designed as scissors, which has two intersecting scissor levers. For up and down movement of the running rail, a cylinder is provided which engages on the one hand on the running rail and on the other hand after a crossing point between two scissor levers. In the running rail is a drive device of the hydraulic cylinder arranged, which comprises an electric hydraulic pump and a valve control unit.

Zur Energieversorgung einer solchen Hebevorrichtung ist erforderlich, dass diese über einen Stromanschluss mit dem örtlichen Versorgungsnetz zu verbinden ist. Sofern ein Stromausfall des Versorgungsnetzes vorliegt, ist ein Betrieb der Hebebühne nicht möglich. Darüber hinaus weist diese Hebevorrichtung den Nachteil auf, dass die Antriebssteuerung an verschiedene Stromversorgungsnetze in den jeweiligen Ländern angepasst werden muss, damit ein Betrieb der Hebevorrichtung möglich wird. Zusätzlich ist durch diese Stromversorgung ein örtlich begrenzter Einsatzbereich gegeben.To power such a lifting device is required that it is to be connected via a power connection to the local power supply. If there is a power failure of the supply network, operation of the lift is not possible. In addition, this lifting device has the disadvantage that the drive control must be adapted to different power grids in the respective countries, so that operation of the lifting device is possible. In addition, this power supply provides a localized area of use.

Aus der US 2005/0045429 A1 geht eine Hebevorrichtung hervor, welche aus einer Gruppe von Einsäulen-Hebebühnen besteht. Entlang einer Hubsäule ist ein Lastaufnahmeelement auf und ab bewegbar über eine Antriebssteuerung angesteuert. Zur Energieversorgung ist ein Energiespeicher in Form einer Batterie an der Hubsäule vorgesehen.From the US 2005/0045429 A1 goes out a lifting device, which consists of a group of single-column lifts. Along a lifting column, a load-receiving element is driven movable up and down via a drive control. For energy supply, an energy storage in the form of a battery is provided on the lifting column.

Aus der DE 202 14 088 U1 ist eine Hebevorrichtung mit einem Akkumulator für einen Elektromotor bekannt. Mehrere Einzelakkumulatoren sind über eine Steckerleiste miteinander verbunden, so dass beim Aufladen der Hebevorrichtung diese eine Steckerleiste an eine Ladestation anschließbar ist. Die Ladestation selbst ist jedoch an die jeweilige Versorgungsspannung anzupassen.From the DE 202 14 088 U1 a lifting device with an accumulator for an electric motor is known. Several individual batteries are connected to each other via a connector strip, so that when charging the lifting device, this a connector strip is connected to a charging station. However, the charging station itself must be adapted to the respective supply voltage.

Aus der JP 10-139 384 A geht eine Hebevorrichtung hervor, welche zum autarken Betrieb unabhängig einer Versorgungsspannung ausgebildet ist. Hierfür weist die Hebevorrichtung Solarzellen auf, um die Batterien mit Energie zu versorgen.From the JP 10-139384 A shows a lifting device, which is designed for autonomous operation independent of a supply voltage. For this purpose, the lifting device has solar cells in order to supply the batteries with energy.

Der Erfindung liegt die Aufgabe zugrunde, eine Hebevorrichtung zum Anheben von Lasten, insbesondere Fahrzeugen, zu schaffen, welche eine ortsunabhängige Energieversorgung zum Betrieb der Hebevorrichtung ermöglicht.The invention has for its object to provide a lifting device for lifting loads, especially vehicles, which a location-independent power supply for operation of the lifting device allows.

Diese Aufgabe wird durch eine Hebevorrichtung gemäß Anspruch 1 gelöst. Diese Hebevorrichtung weisst einen Energiespeicher auf, der an einem Hubelement oder an einer Lastaufnahme der Hebevorrichtung vorgesehen ist und die Antriebssteuerung sowie die Antriebseinrichtung der Hebevorrichtung mit Energie versorgt. Durch die Integration eines Energiespeichers an der Hebevorrichtung oder innerhalb des Arbeitsbereiches der Lastaufnahme oder der Hubelemente, wie beispielsweise am Boden oder in der Nähe des Bodens, an dem die Hubelemente sich abstützen, ist diese im Betrieb autark und unabhängig von den örtlich vorliegenden Stromnetzen, insbesondere deren Frequenzen oder Spannungen. Vielmehr kann eine einheitliche Antriebssteuerung und einheitliche Antriebseinrichtung geschaffen werden, welche von den Energiespeichern versorgt werden. Dadurch ist die Herstellung solcher Hebevorrichtungen kostengünstig. Gleichzeitig ist der Aufbau der Komponenten für alle Hebevorrichtungen einheitlich. Durch die Ausgestaltung der Hebevorrichtung mit einem Energiespeicher ist des Weiteren möglich, dass ein unmittelbarer Stromanschluss über ein Kabel mit dem örtlichen Versorgungsnetz nicht erforderlich ist. Dadurch ist der Aufstellort der Hebevorrichtung unabhängig von örtlichen Gegebenheiten beziehungsweise von örtlichen Stromversorgungsanschlüssen.This object is achieved by a lifting device according to claim 1. This lifting device has an energy store, which is provided on a lifting element or on a load receiving device of the lifting device and supplies the drive control and the drive device of the lifting device with energy. By integrating an energy storage device on the lifting device or within the working range of the load or lifting elements, such as on the ground or in the vicinity of the soil on which the lifting elements are supported, this is self-sufficient in operation and independent of the local power grids, in particular their frequencies or voltages. Rather, a uniform drive control and uniform drive device can be created, which are supplied by the energy storage. As a result, the production of such lifting devices is inexpensive. At the same time, the structure of the components is uniform for all lifting devices. Due to the design of the lifting device with an energy storage is also possible that an immediate power connection via a cable to the local supply network is not required. As a result, the installation location of the lifting device is independent of local conditions or of local power supply connections.

Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Antriebseinrichtung zumindest ein Hydraulikaggregat und eine hydraulische Steuerung zum Antrieb eines hydraulischen Zylinders und vorzugsweise einen Elektromotor aufweist und dass die Antriebseinrichtung an der Lastaufnahme oder dem Hubelement angeordnet ist. Dadurch kann ein komplett geschlossenes Hydrauliksystem für eine Hebevorrichtung bereitgestellt und dieses Hydrauliksystem bereits vor Auslieferung geschlossen und überprüft werden.According to a preferred embodiment of the invention it is provided that the drive device comprises at least one hydraulic unit and a hydraulic control for driving a hydraulic cylinder and preferably an electric motor and that the drive means is arranged on the load receiving or the lifting element. As a result, a completely closed hydraulic system for a lifting device can be provided and this hydraulic system can be closed and checked before delivery.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Antriebssteuerung an der Lastaufnahme oder dem Hubelement oder innerhalb eines Arbeitsbereiches der Lastaufnahme oder am Hubelement angeordnet ist. Dadurch können kurze Stromwege erzielt werden. Gleichzeitig ist die Einsparung von teuren Stromkabeln gegeben. Bevorzugt ist vorgesehen, dass die Antriebssteuerung, die Antriebseinrichtung und der Energiespeicher jeweils einander zugeordnet sind und eine kompakte Einheit bilden. Beispielsweise können alle Komponenten innerhalb der Fahrschiene oder unterhalb der Fahrschiene vorgesehen sein. Ebenso können diese an dem Hubelement angebracht werden. Die Mitbewegung dieser Komponenten ist im Verhältnis zu den zu hebenden Lasten vernachlässigbar.According to a further advantageous embodiment of the invention, it is provided that the drive control on the load receiving or the lifting element or within a working range of the load or is arranged on the lifting element. As a result, short current paths can be achieved. At the same time there is the saving of expensive power cables. It is preferably provided that the drive control, the drive device and the energy storage are each associated with each other and form a compact unit. For example, all components may be provided within the running rail or below the running rail. Likewise, these can be attached to the lifting element. The co-movement of these components is negligible in relation to the loads to be lifted.

Nach einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die Antriebssteuerung drahtlos ausgebildet ist. Dadurch werden beispielsweise zwei oder mehrere Lastaufnahmemittel, die an einer Last oder einem Fahrzeug angreifen, gleichzeitig angesteuert, ohne dass Anschlussleitungen zwischen oder zu den jeweiligen Hebevorrichtungen der Lastaufnahmemittel erforderlich sind. Des Weiteren kann dadurch wiederum eine ortsunabhängige Aufstellung und Ansteuerung der Hebevorrichtung ermöglicht sein.According to a further preferred embodiment of the invention it is provided that the drive control is wireless. As a result, for example, two or more load-receiving means, which engage a load or a vehicle, simultaneously driven, without connecting lines between or to the respective lifting devices of the load-carrying means are required. Furthermore, this in turn allows a location-independent installation and control of the lifting device.

Nach der Erfindung ist vorgesehen, dass der Energiespeicher an einer Schnellwechseleinrichtung anschließbar ist, welche an dem Lastaufnahmemittel oder dem Hubelement angeordnet ist. Dadurch ist eine ständige Betriebsbereitschaft gegeben. Diese Betriebsbereitschaft liegt auch dann vor, wenn über eine längere Zeitdauer ein Stromausfall besteht. Darüber hinaus kann durch die Schnellwechseleinrichtung ein einfacher und schneller Austausch des entladenen Energiespeichers mit einem vollständig aufgeladenen Energiespeicher erfolgen.According to the invention, it is provided that the energy store can be connected to a quick-change device, which is arranged on the load-receiving means or the lifting element. As a result, a permanent operational readiness is given. This operational readiness is also present if there is a power failure over a longer period of time. In addition, can be done with a fully charged energy storage by the quick change device, a simple and quick replacement of the discharged energy storage.

Das Hubelement der Hebevorrichtung kann gemäß einer ersten Ausführungsform als Halbschere ausgebildet sein. Eine solche Halbschere kann ein Lastaufnahmemittel auf und ab bewegen. Ebenso können auch zwei oder mehrere Halbscheren gemeinsam an einem Lastaufnahmemittel angreifen. Analoges gilt für den Einsatz einer Schere, welche zwei sich kreuzende Scherenhebel umfasst. Des Weiteren kann das Hubelement alternativ als Hubstempel ausgebildet sein. Des Weiteren können zwei oder mehrere getrennt zueinander angeordnete Scherenhebel zwischen einer Bodenbefestigung und einem Lastaufnahmemittel angeordnet sein, die ein geführtes Auf- und Abbewegen des Lastaufnahmemittels unter Zusammenwirken mit dem hydraulischen Zylinder bewirken. Auch kann eine beliebige Kombination der vorgenannten Ausführungsformen vorgesehen sein.The lifting element of the lifting device can be designed according to a first embodiment as a half-scissors. Such a half-scissors can move a load-lifting device up and down. Likewise, two or more half shears can attack together on a load handling device. The same applies to the use of a pair of scissors, which includes two intersecting scissor levers. Furthermore, the lifting element may alternatively be designed as a lifting ram. Furthermore, two or more separately arranged scissor levers between a bottom attachment and a load-receiving means may be arranged, which cause a guided up and down movement of the load-receiving means in cooperation with the hydraulic cylinder. Also, any combination of the aforementioned embodiments may be provided.

Das Lastaufnahmemittel der Hebevorrichtung kann beispielsweise als Radgreifer ausgebildet sein. Alternativ kann das Lastaufnahmemittel als schwenkbare Tragarme oder als Fahrschiene ausgebildet sein.The load-receiving means of the lifting device may be formed, for example, as a wheel gripper. Alternatively, the load receiving means may be formed as a pivotable support arms or as a running rail.

Des Weiteren ist bevorzugt an der Antriebssteuerung oder dem zumindest einen Energiespeicher der Hebevorrichtung ein Ladekabel anschließbar. Bei dieser Ausführungsform weist die Antriebssteuerung oder der Energiespeicher oder beide vorzugsweise eine Ladeschaltung zur Überwachung des Ladezustandes des Energiespeichers auf. Dies ermöglicht, dass beispielsweise der Energiespeicher beziehungsweise der Wechselenergiespeicher ohne Entnahme geladen werden kann, wodurch für den Antrieb der Hebevorrichtung quasi lediglich ein Lichtstrom erforderlich ist, um den Energiespeicher aufzuladen. In Deutschland liegt beispielsweise eine 1-polige Netzspannung von 230 V vor. Der Betrieb der Hebevorrichtung erfolgt über den Energiespeicher.
