- the object of the present invention is to provide a device which allows faster setting up of a lifting unit for lifting vehicles and thereby increases operating safety.
- the device for setting up at least one lifting unit for lifting vehicles comprises a control unit, a remote control unit for transmitting control signals to the control unit, and a load sensor which transmits measuring signals to the control unit for determining the load of a lifting unit.
- a remote control unit in the sense of this invention is a mobile control unit that a user can carry with him.
- the lifting unit is positioned at receiving points of the object to be lifted and may include a lifting ram and load receptacles mounted on the lifting ram.
- the load sensor can transmit load values directly to the control unit or also values (eg voltage values of a load sensor based on voltage measurements) on the basis of which the control unit can determine the load capacity.
- the load sensor may be designed as a pressure sensor in the hydraulic system.
- control unit receives control signals of the remote control unit and outputs corresponding control commands to the lifting unit.
- both the lifting ram can be positioned vertically and in the longitudinal direction of the vehicle as well as the located on the lifting ram load receptacles are moved in the transverse direction.
- control unit monitors based on the transmitted signals from the load sensor, the load of the lifting unit and interrupts the control of the lifting unit by means of the remote control unit, when the determined load of the lifting unit is greater than one is predetermined load point.
- Load point in the context of this invention is a predetermined value for the load acting on a lifting unit, the achievement of this value means that the lifting unit is under load and the weight of the vehicle to be lifted at least partially acts on the lifting unit.
- the control circuit ensures that after completion of setting up a lifting unit, characterized by reaching the load point, the remote control unit is deactivated.
- the weight of the object to be lifted automatically generates a predetermined load against the force of the lifting unit when the receptacles on the lifting units are in contact with the receiving points of the object.
- the control signals emanating from the remote control unit are then automatically deactivated.
- the safety of the worker can be ensured in a particularly simple manner, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed can.
- the lifting units can be controlled individually with the remote control unit, wherein the control unit is set to suppress control by means of the remote control unit of those lifting units whose determined load is greater than a predetermined load point of this lifting unit.
- the remote control of this lifting unit is suppressed, while the other Lifting units that have not yet reached their load point can still be positioned with the remote control unit.
- the control unit can be set up in such a way that only one lifting unit for setting up can be moved with the remote control unit while the other lifting units are blocked. This avoids that a user who is to set up in the vicinity of the lifting units, injured by a second moving lifting unit, which he has not in sight.
- the lifting unit can be moved with the remote control unit into a first position in which images located on the lifting unit can be positioned vertically below receiving points of an object to be lifted. Furthermore, the lifting unit with the remote control unit can be moved to a second position, are in contact with the receptacles of the lifting unit with receiving points of an object to be lifted. This can ensure that after the horizontal alignment of the images, they can be brought in a particularly simple manner by vertical method safely in contact with the receiving points of the object to be lifted.
- At least one illumination unit and / or at least one image acquisition unit can be provided on the lifting unit, and at least one image output unit can be provided on a fixed operator control unit and / or the remote control unit for the reproduction of the data recorded by the image acquisition unit.
- a lighting unit can also be provided on the remote control unit, with which the user can illuminate the working space under the vehicle.
- the lifting unit may be executed in underfloor construction and / or is located in a pit which is arranged in a bottom surface. Furthermore, the free areas of a pit opening, which may be arranged in a floor surface, may be at least partially concealable with mobile cover units. This ensures in a particularly simple manner that through the pit opening, which is necessary to move the lifting unit in the longitudinal direction of the object to be lifted, no objects or people can fall into the pit. Thus, the lifting unit is secured against damage and extended their life.
- the control unit can calibrate at the load point to a common starting value.
- the movement of the lifting ram is quasi-synchronous.
- the movement of the lifting ram is synchronized, so that the stroke difference of the individual lifting ram during the lifting process is less than 50 mm.
- the mounting points for the lifting units on a truck can be at different heights. Therefore, it is important that after setting up the lifting units, i. After positioning the lifting units and reaching the load point, the positions of the lifting units are calibrated to a common starting value.
- data concerning the position of the pickup points on the items to be lifted may be transmitted through the wireless remote control unit wired remote control unit and / or the stationary control unit are input to the lifting device and / or stored in a database located in one of said control units.
- This can be stored in a particularly simple manner, the coordinates of the recording points of the objects in the form of a database in the lifting device. Since, for example, the same types of trucks have the same coordinates of pick-up points, this results in the advantage that the coordinates of the pick-up points do not have to be reentered for each item of the same type or type to be lifted.
- a fixed reference point for determining the position of the vehicle is still required.
- the stored pick-up points determine the position of the pick-up points relative to this fixed reference point.
- This fixed reference point can be specified, for example, by means of a wheel well into which the vehicle enters.
- the remote control unit can be a wireless remote control unit. This increases the freedom of movement of the worker in often limited by the vehicle and the lift working space and reduces the risk of tripping through lying cable strands.
- a first lifting unit may be stationary in a substantially horizontal direction, wherein at least one further second lifting unit may be displaceable in a predetermined, substantially horizontal longitudinal direction of an article to be lifted.
- control unit can be set up such that the lifting units can be moved at different speed levels during the setting-up process.
- control unit may be configured such that for positioning in a first position, the lifting unit is moved quickly and for positioning in the second position until reaching the load point is slowly movable.
- a fast method of lifting unit would be dangerous because in a dangerous situation, the first user could not stop the lifting dies himself and the response time of the second user to the stationary operating unit would take too long.
- a user who is equipped with a mobile remote control unit for setting up the lifting units even with a quick movement of the lifting unit in the first position to monitor their correct alignment and positioning in the vicinity of the lifting reliable.
- control unit and the remote control unit for removing and installing aggregate units can be used.
- the lifting units are relieved after setting up and lifting the vehicle by jacking the vehicle, so that the load of the lifting units falls below the load point. After falling below the load points of the lifting units they can be controlled again with the remote control unit.
- a user located below the jacked-up vehicle positions a lifting unit by means of the remote control unit under the vehicle assembly to be picked up.
- the carrying capacity of vehicle aggregates is generally smaller than the predetermined load point of the lifting unit, so that by means of the remote control unit, the lifting unit under load, ie with the recorded aggregate, and can be lowered independently of the movement or position of the other lifting units.
- the method for setting up at least one lifting unit for lifting vehicles comprises the positioning of a lifting unit by means of a remote control unit into a first position in which shots located on the lifting unit are positioned vertically below receiving points of an object to be lifted.
- the method further comprises positioning a lifting unit by means of a remote control unit in a second position, in which the recordings of the lifting unit are in contact with the receiving points; and measuring the load of a lifting unit.
- the method comprises monitoring the load of a lifting unit; and interrupting the actuation of the lifting unit via the remote control unit when the determined lifting capacity of the lifting unit is greater than a predetermined load point.
- the method may comprise the step of, after reaching the load point of the lifting unit, sending a control signal for locking the lifting unit and for deactivating the remote control unit, and controlling the lifting unit by means of control signals received by a stationary operating unit.
- the present invention enables a fast, cost-effective and user-friendly setting up of one or more lifting units for lifting vehicles.
- the presence of a remote control can control the orientation of recordings from anywhere.
- a worker monitoring the alignment also takes control of the lift unit. Merging these two functions to one person can significantly speed alignment. Thus, especially in workshops with high utilization, the efficiency can be improved and the staffing requirements are reduced, since only one worker for aligning and controlling the lifting system is needed.
- the control unit according to the invention meets the high safety requirements in the operation of lifting platforms, since after reaching the load point, the control of the respective lifting unit is automatically deactivated via the remote control unit.
- This can ensure a particularly simple way worker safety, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed .
- By providing a camera and a lighting unit on the lifting units or the remote control unit, as well as an image output unit on the control units the workers no longer have to go under the objects to monitor the alignment, which means the risk of burns on hot exhaust parts or sharp-edged injuries Objects is reduced.

Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Einrichten einer Hubeinheit zum Heben von Fahrzeugen um ein schnelle und bediensichere Positionierung der Hubeinheit an Aufnahmepunkten am Fahrzeug zu ermöglichen.The present invention relates to an apparatus and a method for setting up a lifting unit for lifting vehicles in order to enable a quick and safe positioning of the lifting unit at pick-up points on the vehicle.
Aus dem Stand der Technik sind Hebebühnen für Fahrzeuge zum Anheben und Absenken der Fahrzeuge bekannt, die beispielsweise Stempel oder Greifarme aufweisen mit denen Gegenstände angehoben werden können. Die Stempel oder Tragarme müssen dabei von einem Benutzer der Hebeanlage manuell unterhalb des zu hebenden Gegenstands positioniert werden. Aufgabe des Benutzers ist es dabei Aufnahmebereiche, die an den Tragarmen oder an den Stempeln der Hebebühne vorgesehen sind, an den dazugehörigen Aufnahmepunkten des zu hebenden Gegenstands auszurichten. Da es sich bei den zu hebenden Gegenständen im Allgemeinen um Lasten mit einer hohen Gewichtskraft und großen Abmessungen wie beispielsweise Lastkraftwagen, handelt, deren Unterseite von Außen schwer einzusehen ist, muss sich bei der Ausrichtung der Aufnahmen stets ein Benutzer unterhalb der Last befinden, um die korrekte Ausrichtung zu überwachen. Die Steuerung der Bewegung der Stempel oder Tragarme der Hebelanlange erfolgt über eine ortsfeste Bedieneinheit durch einen weiteren Benutzer. Durch die Aufteilung der Steuerung und Überwachung auf zwei Arbeiter wird bei solchen Vorrichtungen der Aufwand bei der Ausrichtung erheblich erhöht, da beide Arbeiter permanent miteinander akustisch kommunizieren müssen. Ein weiteres Problem ist darin zu sehen, dass ein Arbeiter der sich bei der Überwachung der Ausrichtung unterhalb der Last befindet, Gefahren ausgesetzt ist wie beispielsweise Verbrennungen durch heiße Auspuffteile von Lastkraftwagen zu erleiden oder sich an scharfkantigen Bauteilen zu verletzen wodurch sich ein Sicherheitsrisiko für diese Person ergibt.From the prior art lifts for vehicles for raising and lowering of the vehicles are known, for example, have pistons or gripping arms with which objects can be lifted. The stamp or support arms must be positioned by a user of the lifting system manually below the object to be lifted. The task of the user is to align receiving areas, which are provided on the support arms or on the punches of the lift, at the associated receiving points of the object to be lifted. Since the objects to be lifted are generally loads with a high weight and large dimensions such as trucks, the underside of which is difficult to see from the outside, a user always has to be below the load when aligning the seats to monitor correct alignment. The control of the movement of the punch or support arms of Hebelanlange via a stationary control unit by another user. By dividing the control and monitoring of two workers, the effort in alignment is significantly increased in such devices, since both workers must communicate permanently with each other acoustically. Another problem is that a worker who is under load to monitor alignment is exposed to hazards such as burning or being hit by hot truck exhaust manifolds sharp-edged components which results in a security risk for this person.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung bereitzustellen, die schnelleres Einrichten einer Hubeinheit zum Heben von Fahrzeugen ermöglicht und dabei die Bediensicherheit erhöht.The object of the present invention is to provide a device which allows faster setting up of a lifting unit for lifting vehicles and thereby increases operating safety.
Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1 und 9 gelöst. Die abhängigen Patentansprüche betreffen vorteilhafte Ausgestaltungen der Erfindung.This object is solved by the features of
Erfindungsgemäß umfasst die Vorrichtung zum Einrichten mindestens einer Hubeinheit zum Heben von Fahrzeugen eine Steuereinheit, eine Fernbedieneinheit zur Übermittlung von Ansteuersignalen an die Steuereinheit, und einen Lastsensor, der zur Ermittlung der Traglast einer Hubeinheit Messsignale an die Steuereinheit übermittelt. Eine Fernbedieneinheit im Sinne dieser Erfindung ist eine mobile Bedieneinheit, die ein Nutzer mit sich tragen kann. Die Hubeinheit wird an Aufnahmepunkten des zu hebenden Gegenstandes positioniert wird und kann einen Hubstempel und auf dem Hubstempel befestigte Lastaufnahmen umfassen. Der Lastsensor kann direkt Traglastwerte an die Steuereinheit übermitteln oder auch Werte (z.B. Spannungswerte eines auf Spannungsmessungen basierten Lastsensors) anhand derer die Steuereinheit die Traglast ermitteln kann. Der Lastsensor kann als Drucksensor im Hydrauliksystem ausgebildet sein. Weiterhin empfängt die Steuereinheit Ansteuersignale der Fernbedieneinheit und gibt entsprechende Steuerbefehle an die Hubeinheit aus. Beispielweise können mit der Fernbedieneinheit auf diese Weise sowohl der Hubstempel vertikal und in Längsrichtung des Fahrzeugs positioniert werden als auch die auf dem Hubstempel befindlichen Lastaufnahmen in Querrichtung verfahren werden. Weiterhin überwacht die Steuereinheit auf Basis der vom Lastsensor übermittelten Messsignale die Traglast der Hubeinheit und unterbricht die Ansteuerung der Hubeinheit mittels der Fernbedieneinheit, wenn die ermittelte Traglast der Hubeinheit größer als ein vorbestimmter Lastpunkt ist. Lastpunkt im Sinne dieser Erfindung ist ein vorbestimmter Wert für die auf eine Hubeinheit wirkende Traglast, wobei das Erreichen dieses Wertes bedeutet, dass die Hubeinheit unter Last steht und die Gewichtskraft des zu hebenden Fahrzeugs zumindest teilweise auf die Hubeinheit einwirkt.According to the invention, the device for setting up at least one lifting unit for lifting vehicles comprises a control unit, a remote control unit for transmitting control signals to the control unit, and a load sensor which transmits measuring signals to the control unit for determining the load of a lifting unit. A remote control unit in the sense of this invention is a mobile control unit that a user can carry with him. The lifting unit is positioned at receiving points of the object to be lifted and may include a lifting ram and load receptacles mounted on the lifting ram. The load sensor can transmit load values directly to the control unit or also values (eg voltage values of a load sensor based on voltage measurements) on the basis of which the control unit can determine the load capacity. The load sensor may be designed as a pressure sensor in the hydraulic system. Furthermore, the control unit receives control signals of the remote control unit and outputs corresponding control commands to the lifting unit. For example, with the remote control unit in this way, both the lifting ram can be positioned vertically and in the longitudinal direction of the vehicle as well as the located on the lifting ram load receptacles are moved in the transverse direction. Furthermore, the control unit monitors based on the transmitted signals from the load sensor, the load of the lifting unit and interrupts the control of the lifting unit by means of the remote control unit, when the determined load of the lifting unit is greater than one is predetermined load point. Load point in the context of this invention is a predetermined value for the load acting on a lifting unit, the achievement of this value means that the lifting unit is under load and the weight of the vehicle to be lifted at least partially acts on the lifting unit.
Durch das Vorsehen einer Fernbedieneinheit kann ein einzelner Arbeiter, der sich unterhalb einer zu hebenden Last befindet, die Bewegung der Hubeinheit, an der sich die auszurichtenden Aufnahmen befinden, steuern und dabei gleichzeitig deren korrekte Ausrichtung überwachen. Gleichzeitig stellt die erfindungsgemäße Steuerschaltung sicher, dass nach Abschluss des Einrichtens einer Hubeinheit, gekennzeichnet durch das Erreichen des Lastpunkts, die Fernbedieneinheit deaktiviert wird. Mit anderen Worten erzeugt die Gewichtskraft des zu hebenden Gegenstandes selbsttätig eine vorbestimmte Last gegen die Kraft der Hubeinheit, wenn die Aufnahmen an den Hubeinheiten mit den Aufnahmepunkten des Gegenstandes in Kontakt stehen. Bei dieser Last werden dann die von der Fernbedieneinheit ausgehenden Steuersignale selbsttätig deaktiviert. Damit kann auf besonders einfache Weise die Sicherheit des Arbeiters sichergestellt, da er das Fahrzeug aufgrund der deaktivierten Fernbedieneinheit nicht anheben kann solange er sich unter dem Fahrzeug befindet, wo seine Sicherheit im Falle einer fehlerhaften Positionierung der Hubeinheit am Fahrzeug beim Anheben des Fahrzeuges nicht gewährleistet werden kann.By providing a remote control unit, a single worker, who is below a load to be lifted, can control the movement of the lift unit on which the images to be aligned are located while monitoring their correct orientation. At the same time, the control circuit according to the invention ensures that after completion of setting up a lifting unit, characterized by reaching the load point, the remote control unit is deactivated. In other words, the weight of the object to be lifted automatically generates a predetermined load against the force of the lifting unit when the receptacles on the lifting units are in contact with the receiving points of the object. At this load, the control signals emanating from the remote control unit are then automatically deactivated. Thus, the safety of the worker can be ensured in a particularly simple manner, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed can.
Bei einer Hebebühne mit mehreren Hubeinheiten können die Hubeinheiten mit der Fernbedieneinheit einzeln angesteuert werden, wobei die Steuereinheit eingerichtet ist, die Steuerung mittels der Fernbedieneinheit derjenigen Hubeinheiten zu unterbinden, deren ermittelte Traglast größer als ein vorbestimmter Lastpunkt dieser Hubeinheit ist. Dies ermöglicht ein besonders schnelles und gleichzeitig sicheres Einrichten einer Hebebühne mit mehreren Hubeinheiten, da nach Abschluss des Einrichtvorgangs für eine Hubeinheit die Fernsteuerung dieser Hubeinheit unterbunden wird, während die anderen Hubeinheiten, die ihren Lastpunkt noch nicht erreicht haben, weiterhin mit der Fernbedieneinheit positioniert werden können. Die Steuereinheit kann derart eingerichtet sein, dass mit der Fernbedieneinheit immer nur eine Hubeinheit zum Einrichten bewegt werden kann währenddessen die anderen Hubeinheiten blockiert sind. Dadurch wird vermieden, dass ein Nutzer, der sich zum Einrichten in der Nähe der Hubeinheiten befindet, von einer zweiten sich bewegenden Hubeinheit, die er nicht im Blick hat, verletzt wird.In a lift with multiple lifting units, the lifting units can be controlled individually with the remote control unit, wherein the control unit is set to suppress control by means of the remote control unit of those lifting units whose determined load is greater than a predetermined load point of this lifting unit. This allows a particularly fast and at the same time safe setting up a lift with multiple lifting units, since the completion of the setup process for a lifting unit, the remote control of this lifting unit is suppressed, while the other Lifting units that have not yet reached their load point can still be positioned with the remote control unit. The control unit can be set up in such a way that only one lifting unit for setting up can be moved with the remote control unit while the other lifting units are blocked. This avoids that a user who is to set up in the vicinity of the lifting units, injured by a second moving lifting unit, which he has not in sight.
Die Hubeinheit kann mit der Fernbedieneinheit in eine erste Stellung verfahrbar sein, in der an der Hubeinheit befindliche Aufnahmen vertikal unterhalb von Aufnahmepunkten eines zu hebenden Gegenstandes positionierbar sind. Weiterhin ist die Hubeinheit mit der Fernbedieneinheit in eine zweite Stellung verfahrbar, in der Aufnahmen der Hubeinheit mit Aufnahmepunkten eines zu hebenden Gegenstandes in Kontakt stehen. Damit kann sichergestellt werden, dass nach der horizontalen Ausrichtung der Aufnahmen, diese auf besonders einfache Weise durch vertikales Verfahren sicher mit den Aufnahmepunkten des zu hebenden Gegenstandes in Kontakt gebracht werden können.The lifting unit can be moved with the remote control unit into a first position in which images located on the lifting unit can be positioned vertically below receiving points of an object to be lifted. Furthermore, the lifting unit with the remote control unit can be moved to a second position, are in contact with the receptacles of the lifting unit with receiving points of an object to be lifted. This can ensure that after the horizontal alignment of the images, they can be brought in a particularly simple manner by vertical method safely in contact with the receiving points of the object to be lifted.
Weiterhin kann an der Hubeinheit zumindest eine Beleuchtungseinheit und/oder zumindest eine Bilderfassungseinheit vorgesehen sein, und an einer ortsfesten Bedieneinheit, und/oder der Fernbedieneinheit kann zumindest eine Bildausgabeeinheit zur Wiedergabe der von der Bilderfassungseinheit aufgenommenen Daten vorgesehen sein. Weiterhin kann auch an der Fernbedieneinheit eine Beleuchtungseinheit vorgesehen, mit der der Nutzer den Arbeitsraum unter dem Fahrzeug ausleuchten kann.Furthermore, at least one illumination unit and / or at least one image acquisition unit can be provided on the lifting unit, and at least one image output unit can be provided on a fixed operator control unit and / or the remote control unit for the reproduction of the data recorded by the image acquisition unit. Furthermore, a lighting unit can also be provided on the remote control unit, with which the user can illuminate the working space under the vehicle.
Da unterhalb zu hebender Lasten meist schlechte Lichtverhältnisse anzutreffen sind ergeben sich Vorteile insbesondere dahingehend, dass durch die Beleuchtungseinheit die Bereiche der Aufnahmepunkte und der Aufnahmen erhellt werden, sodass ein Arbeiter diese Bereiche besser einsehen kann. Durch das Vorsehen einer Bilderfassungseinheit an der Hubeinheit wie beispielsweise einer Kamera können die Gegebenheiten unterhalb eines zu hebenden Gegenstandes erfasst werden. Diese Gegebenheiten können vorteilhaft durch die Bildausgabeeinheiten wahlweise oder gleichzeitig an einer ortsfesten Bedieneinheit, der kabellosen Fernbedieneinheit und/oder der kabelgebunden Fernbedieneinheit ausgegeben werden. Dadurch ergeben sich Vorteile, dass während der Ausrichtung der Aufnahmen an den Aufnahmepunkten ein Arbeiter sich nicht mehr unterhalb eines zu hebenden Gegenstandes befinden muss. Stattdessen kann die Überwachung direkt an der Bildausgabeeinheit erfolgen.Since underneath loads to be lifted are usually poor lighting conditions, there are advantages, in particular, in that the areas of the pick-up points and the shots are illuminated by the lighting unit so that a worker can better see these areas. By providing an image acquisition unit on the lifting unit, such as a camera, the conditions below can be lifted Item are recorded. These circumstances can advantageously be output by the image output units selectively or simultaneously to a fixed operating unit, the wireless remote control unit and / or the wired remote control unit. This results in advantages that during the alignment of the recordings at the receiving points a worker no longer has to be below an object to be lifted. Instead, the monitoring can be done directly on the image output unit.
Die Hubeinheit kann in Unterflurbauweise ausgeführt sein und/oder befindet sich in einer Grube, die in einer Bodenfläche angeordnet ist. Weiterhin können die freien Bereiche einer Grubenöffnung, die in einer Bodenfläche angeordnet sein können, mit mobilen Abdeckeinheiten zumindest teilweise abdeckbar sein. Dadurch wird auf besonders einfache Weise sichergestellt, dass durch die Grubenöffnung, die notwendig ist, um die Hubeinheit in Längsrichtung des zu hebenden Gegenstandes zu verschieben, keine Gegenstände oder Personen in die Grube hineinfallen können. Somit wird die Hubeinheit vor Beschädigungen gesichert und ihre Lebensdauer verlängert.The lifting unit may be executed in underfloor construction and / or is located in a pit which is arranged in a bottom surface. Furthermore, the free areas of a pit opening, which may be arranged in a floor surface, may be at least partially concealable with mobile cover units. This ensures in a particularly simple manner that through the pit opening, which is necessary to move the lifting unit in the longitudinal direction of the object to be lifted, no objects or people can fall into the pit. Thus, the lifting unit is secured against damage and extended their life.
Weiterhin können am Lastpunkt evtl. unterschiedliche Hubhöhen der Hubeinheiten durch die Steuereinheit auf einen gemeinsamen Startwert kalibriert werden. Beim Anheben eines Fahrzeugs unter Verwendung mehrerer Hubeinheiten ist es wichtig, dass die Bewegung der Hubstempel quasi-synchron erfolgt. In der Praxis wird die Bewegung der Hubstempel synchronisiert, so dass die Hubdifferenz der einzelnen Hubstempel während des Hubvorgangs kleiner als 50 mm ist. Beispielsweise können die Aufnahmepunkte für die Hubeinheiten an einem Lastzug auf unterschiedlichen Höhen befinden. Daher ist es wichtig, dass nach Einrichten der Hubeinheiten, d.h. nach Positionierung der Hubeinheiten und Erreichen des Lastpunkts die Stellungen der Hubeinheiten auf einen gemeinsamen Startwert kalibriert werden.Furthermore, at the load point possibly different lifting heights of the lifting units can be calibrated by the control unit to a common starting value. When lifting a vehicle using multiple lifting units, it is important that the movement of the lifting ram is quasi-synchronous. In practice, the movement of the lifting ram is synchronized, so that the stroke difference of the individual lifting ram during the lifting process is less than 50 mm. For example, the mounting points for the lifting units on a truck can be at different heights. Therefore, it is important that after setting up the lifting units, i. After positioning the lifting units and reaching the load point, the positions of the lifting units are calibrated to a common starting value.
Darüber hinaus können Daten bezüglich der Position der Aufnahmepunkte an den zu hebenden Gegenständen über die kabellose Fernbedieneinheit, die kabelgebundene Fernbedieneinheit und/oder die ortsfeste Bedieneinheit an die Hebevorrichtung eingegeben werden und/oder in einer Datenbank gespeichert sein, die sich in einer der genannten Bedieneinheiten befindet. Damit können auf besonders einfache Weise die Koordinaten der Aufnahmepunkte der Gegenstände in Form einer Datenbank in der Hebevorrichtung gespeichert werden. Da beispielsweise gleiche LKW-Typen gleiche Koordinaten von Aufnahmepunkten aufweisen ergibt sich hieraus der Vorteil, dass somit nicht für jeden zu hebenden Gegenstand der gleichen Gattung oder des gleichen Typs die Koordinaten der Aufnahmepunkte neu eingegeben werden müssen. Zur automatischen Einrichtung der Hubeinheit an einem Fahrzeug mittels gespeicherten Aufnahmepunkten ist weiterhin ein fester Bezugspunkt zur Positionsbestimmung des Fahrzeugs erforderlich. Die gespeicherten Aufnahmepunkte bestimmen die Position der Aufnahmepunkte relativ zu diesem festen Bezugspunkt. Dieser feste Bezugspunkt kann beispielsweise mittels einer Radmulde, in die das Fahrzeug einfährt, vorgegeben werden.In addition, data concerning the position of the pickup points on the items to be lifted may be transmitted through the wireless remote control unit wired remote control unit and / or the stationary control unit are input to the lifting device and / or stored in a database located in one of said control units. This can be stored in a particularly simple manner, the coordinates of the recording points of the objects in the form of a database in the lifting device. Since, for example, the same types of trucks have the same coordinates of pick-up points, this results in the advantage that the coordinates of the pick-up points do not have to be reentered for each item of the same type or type to be lifted. For automatic setup of the lifting unit on a vehicle by means of stored recording points a fixed reference point for determining the position of the vehicle is still required. The stored pick-up points determine the position of the pick-up points relative to this fixed reference point. This fixed reference point can be specified, for example, by means of a wheel well into which the vehicle enters.
Die Fernbedieneinheit kann eine kabellose Fernbedieneinheit sein. Dies erhöht die Bewegungsfreiheit des Arbeiters im oft durch das Fahrzeug und die Hebebühne begrenzten Arbeitsraum und reduziert die Stolpergefahr durch herumliegende Kabelstränge.The remote control unit can be a wireless remote control unit. This increases the freedom of movement of the worker in often limited by the vehicle and the lift working space and reduces the risk of tripping through lying cable strands.
Weiterhin kann eine erste Hubeinheit in einer im Wesentlichen horizontalen Richtung ortsfest sein, wobei zumindest eine weitere zweite Hubeinheit in einer vorbestimmten, im Wesentlichen horizontalen Längsrichtung eines zu hebenden Gegenstandes verschiebbar sein kann. Damit kann auf einfache Weise das Anheben von Gegenständen unterschiedlicher Länge ermöglicht werden, da durch die Verschiebbarkeit der zweiten Hubeinheit verschiedene Abstände zwischen den Aufnahmepunkten an den zu hebenden Gegenständen einstellbar sind. Infolge dessen kann die Hubvorrichtung individuell an den jeweiligen zu hebenden Gegenstand angepasst werden.Furthermore, a first lifting unit may be stationary in a substantially horizontal direction, wherein at least one further second lifting unit may be displaceable in a predetermined, substantially horizontal longitudinal direction of an article to be lifted. Thus, the lifting of objects of different lengths can be made possible in a simple manner, since the displaceability of the second lifting unit different distances between the receiving points on the objects to be lifted are adjustable. As a result, the lifting device can be individually adapted to the respective object to be lifted.
Weiterhin kann die Steuereinheit derart eingerichtet sein, dass die Hubeinheiten während des Einrichtvorgangs in verschiedenen Geschwindigkeitsstufen verfahrbar sind. Insbesondere kann die Steuereinheit derart eingerichtet sein, dass zur Positionierung in eine erste Stelllung die Hubeinheit schnell verfahrbar ist und zur Positionierung in die zweite Stellung bis zum Erreichen des Lastpunkts langsam verfahrbar ist. Bei dem aus dem Stand der Technik bekannten Einrichten, wo ein erster Nutzer sich zur Überprüfung der Ausrichtung der Aufnahmen unterhalb der Last befindet und ein zweiter Nutzer die Steuerung der Bewegung der Hubeinheiten über eine ortsfeste Bedieneinheit steuert, wäre ein schnelles Verfahren der Hubeinheit gefährlich, da in einer Gefahrensituation der erste Benutzer die Hubstempel nicht selbst stoppen könnte und die Reaktionszeit des zweiten Benutzers an der ortsfesten Bedieneinheit zu lange dauern würde. Dahingegen kann ein Nutzer, der mit einer mobilen Fernbedieneinheit zum Einrichten der Hubeinheiten ausgestattet ist, auch bei einer schnellen Bewegung der Hubeinheit in die erste Stellung deren korrekte Ausrichtung und Positionierung in der Nähe der Hubeinheit betriebssicher überwachen.Furthermore, the control unit can be set up such that the lifting units can be moved at different speed levels during the setting-up process. In particular, the control unit may be configured such that for positioning in a first position, the lifting unit is moved quickly and for positioning in the second position until reaching the load point is slowly movable. In the known from the prior art setup, where a first user is to check the orientation of the recordings below the load and a second user controls the control of the movement of the lifting units via a stationary control unit, a fast method of lifting unit would be dangerous because in a dangerous situation, the first user could not stop the lifting dies himself and the response time of the second user to the stationary operating unit would take too long. On the other hand, a user who is equipped with a mobile remote control unit for setting up the lifting units, even with a quick movement of the lifting unit in the first position to monitor their correct alignment and positioning in the vicinity of the lifting reliable.
Weiterhin kann die Steuereinheit und die Fernbedieneinheit zum Aus- und Einbau von Aggregatseinheiten, beispielsweise einem Getriebe, verwendet werden. Hierzu werden die Hubeinheiten nach dem Einrichten und Anheben des Fahrzeugs durch Aufbocken des Fahrzeugs entlastet, so dass die Traglast der Hubeinheiten unter den Lastpunkt fällt. Nach Unterschreiten der Lastpunkte der Hubeinheiten können diese wieder mit der Fernbedieneinheit gesteuert werden. Ein unterhalb des aufgebockten Fahrzeugs befindlicher Nutzer positioniert eine Hubeinheit mittels der Fernbedieneinheit unter dem aufzunehmenden Fahrzeugaggregat. Die Tragkraft von Fahrzeugaggregaten ist in der Regel kleiner als der vorbestimmte Lastpunkt der Hubeinheit, so dass mittels der Fernbedieneinheit die Hubeinheit unter Last, d.h. mit dem aufgenommenen Aggregat, und unabhängig von der Bewegung oder Stellung der anderen Hubeinheiten abgesenkt werden kann.Furthermore, the control unit and the remote control unit for removing and installing aggregate units, such as a transmission, can be used. For this purpose, the lifting units are relieved after setting up and lifting the vehicle by jacking the vehicle, so that the load of the lifting units falls below the load point. After falling below the load points of the lifting units they can be controlled again with the remote control unit. A user located below the jacked-up vehicle positions a lifting unit by means of the remote control unit under the vehicle assembly to be picked up. The carrying capacity of vehicle aggregates is generally smaller than the predetermined load point of the lifting unit, so that by means of the remote control unit, the lifting unit under load, ie with the recorded aggregate, and can be lowered independently of the movement or position of the other lifting units.
Weiterhin umfasst das Verfahren zum Einrichten mindestens einer Hubeinheit zum Heben von Fahrzeugen die Positionierung einer Hubeinheit mittels einer Fernbedieneinheit in eine erste Stellung, in der an der Hubeinheit befindliche Aufnahmen vertikal unterhalb von Aufnahmepunkten eines zu hebenden Gegenstandes positioniert sind. Das Verfahren umfasst weiterhin die Positionierung einer Hubeinheit mittels einer Fernbedieneinheit in eine zweite Stellung, in der die Aufnahmen der Hubeinheit mit den Aufnahmepunkten in Kontakt stehen; und das Messen der Traglast einer Hubeinheit. Weiterhin umfasst das Verfahren das Überwachen der Traglast einer Hubeinheit; und das Unterbrechen der Ansteuerung der Hubeinheit über die Fernbedieneinheit, wenn die ermittelte Traglast der Hubeinheit größer ist als ein vorbestimmter Lastpunkt ist.Furthermore, the method for setting up at least one lifting unit for lifting vehicles comprises the positioning of a lifting unit by means of a remote control unit into a first position in which shots located on the lifting unit are positioned vertically below receiving points of an object to be lifted. The method further comprises positioning a lifting unit by means of a remote control unit in a second position, in which the recordings of the lifting unit are in contact with the receiving points; and measuring the load of a lifting unit. Furthermore, the method comprises monitoring the load of a lifting unit; and interrupting the actuation of the lifting unit via the remote control unit when the determined lifting capacity of the lifting unit is greater than a predetermined load point.
Weiterhin kann das Verfahren den Schritt umfassen, das nach Erreichen des Lastpunkts der Hubeinheit ein Steuersignal zur Arretierung der Hubeinheit und zur Deaktivierung der Fernbedieneinheit gesendet wird, und die Hubeinheit mittels von einer ortsfesten Bedieneinheit empfangen Steuersignale gesteuert wird.Furthermore, the method may comprise the step of, after reaching the load point of the lifting unit, sending a control signal for locking the lifting unit and for deactivating the remote control unit, and controlling the lifting unit by means of control signals received by a stationary operating unit.
Zusammenfassend wird durch die vorliegende Erfindung ein schnelles, kostengünstiges und bediensicheres Einrichten einer oder mehrerer Hubeinheiten zum Heben von Fahrzeugen ermöglicht.In summary, the present invention enables a fast, cost-effective and user-friendly setting up of one or more lifting units for lifting vehicles.
Durch das Vorhandensein einer Fernbedienung kann die Ausrichtung von Aufnahmen von einem beliebigen Ort gesteuert werden. Vorzugsweise übernimmt ein Arbeiter, der die Ausrichtung überwacht auch die Steuerung der Hubeinheit. Durch die Zusammenlegung dieser zwei Funktionen auf eine Person kann die Ausrichtung wesentlich beschleunigt werden. Insbesondere in Werkstätten mit hoher Auslastung kann somit die Effizienz verbessert werden und der Personalbedarf reduziert werden, da nur ein Arbeiter zum Ausrichten und Steuern der Hebeanlage benötigt wird.The presence of a remote control can control the orientation of recordings from anywhere. Preferably, a worker monitoring the alignment also takes control of the lift unit. Merging these two functions to one person can significantly speed alignment. Thus, especially in workshops with high utilization, the efficiency can be improved and the staffing requirements are reduced, since only one worker for aligning and controlling the lifting system is needed.
Gleichzeitig wird die erfindungsgemäße Steuereinheit den hohen Sicherheitsanforderungen beim Betrieb von Hebebühnen gerecht, da nach Erreichen des Lastpunkts die Steuerung der jeweiligen Hubeinheit über die Fernbedieneinheit automatisch deaktiviert wird. Damit kann auf besonders einfache Weise Sicherheit des Arbeiters sichergestellt, da er das Fahrzeug aufgrund der deaktivierten Fernbedieneinheit nicht anheben kann solange er sich unter dem Fahrzeug befindet, wo seine Sicherheit im Falle einer fehlerhaften Positionierung der Hubeinheit am Fahrzeug beim Anheben des Fahrzeuges nicht gewährleistet werden kann. Durch das Vorsehen einer Kamera sowie einer Beleuchtungseinheit an den Hubeinheiten oder der Fernbedieneinheit, sowie einer Bildausgabeeinheit an den Bedieneinheiten müssen sich die Arbeiter nicht mehr unter die Gegenstände begeben, um die Ausrichtung zu Überwachung, womit die Gefahr von Verbrennungen an heißen Auspuffteilen oder Verletzungen durch scharfkantige Gegenstände vermindert wird.At the same time, the control unit according to the invention meets the high safety requirements in the operation of lifting platforms, since after reaching the load point, the control of the respective lifting unit is automatically deactivated via the remote control unit. This can ensure a particularly simple way worker safety, since he can not lift the vehicle due to the deactivated remote control unit as long as he is under the vehicle, where his safety in case of incorrect positioning of the lifting unit on the vehicle when lifting the vehicle can not be guaranteed , By providing a camera and a lighting unit on the lifting units or the remote control unit, as well as an image output unit on the control units, the workers no longer have to go under the objects to monitor the alignment, which means the risk of burns on hot exhaust parts or sharp-edged injuries Objects is reduced.

In einer weiteren nicht dargestellten Ausführungsform kann die Hebeanlage nach Eingabe der Positionsdaten der Aufnahmepunkte die Hubeinheiten selbsttätig in eine geeignete Position verfahren in der der zu hebende Gegenstand gehoben werden kann. Anschließend kann mit Hilfe der Bildausgabeeinheit die korrekte Ausrichtung der Position der Hubeinheiten kontrolliert werden. Beim Heben von Lastkraftwagen werden anhand einer bekannten Position eines Rades einer Achse beispielsweise die Aufnahmepunkte an der Vorderachse sowie aller weiteren Achsen aus der Datenbank gelesen, sodass sich die Hubeinheiten selbsttätig in eine günstige Position zum Anheben des Gegenstandes beispielsweise des LKWs verfahren können. Zur Bestimmung der Position des genannten Referenzrades kann eine ortsfeste Radmulde als Positionierungshilfe vorgesehen sein.In another embodiment, not shown, the lifting system after entering the position data of the receiving points, the lifting units automatically moved to a suitable position in which the object to be lifted can be lifted. Subsequently, the correct orientation of the position of the lifting units can be controlled by means of the image output unit. When lifting trucks are read from a known position of a wheel of an axle, for example, the receiving points on the front axle and all other axes from the database, so that the lifting units can automatically move into a favorable position for lifting the article, for example, the truck. To determine the position of said reference wheel, a stationary wheel well may be provided as a positioning aid.
Nach Beendigung des Einrichtens der Hubeinheit wird das Fahrzeug mittels der ortsfesten Bedieneinheit angehoben, so dass die Fahrzeugreifen nicht mehr mit der Bodenfläche in Kontakt stehen.
Die Hubhöhe der Hubeinheit am Lastpunkt wird als Nullpunkt für den nachfolgenden Hubvorgang kalibriert. Damit ist der Einrichtvorgang für diese Hubeinheit abgeschlossen.The lifting height of the lifting unit at the load point is calibrated as the zero point for the subsequent lifting operation. This concludes the setup process for this lift unit.
Die einzelnen Merkmale der Erfindung sind selbstverständlich nicht auf die beschriebenen Kombinationen von Merkmalen in Rahmen der vorgestellten Ausführungsbeispiele beschränkt und können in Abhängigkeit vorgegebener Vorrichtungsparameter auch in anderen Kombinationen eingesetzt werden.Of course, the individual features of the invention are not limited to the described combinations of features in the context of the presented embodiments and can also be used in other combinations depending on predetermined device parameters.
