Description

Die Erfindung betrifft eine Hubvorrichtung mit mindestens einem Teleskoprohr oder - zylinder, bestehend aus einem ersten und einem zweiten ringförmigen Band, wobei Mittel vorgesehen sind, um das erste Band spiralförmig transversal orthogonal um eine Mittelachse anzuordnen und das zweite Band um sich selbst gewickelt anzuordnen, wobei die Windungen des zweiten Bandes zur Mittelachse transversal parallel liegen, und um das erste Band in eine eingezogen gestapelte Stellung und das zweite Band in eine eingezogene spiralförmige Stellung zu überführen. Die Erfindung betrifft weiter die Verwendung einer solchen Hubeinrichtung.The invention relates to a lifting device with at least one telescopic tube or cylinder, consisting of a first and a second annular band, wherein means are provided to arrange the first band spirally transversely orthogonal about a central axis and to arrange the second band wound around itself, wherein the turns of the second band are transversely parallel to the central axis, and to transfer the first band to a retracted stowed position and the second band to a retracted helical position. The invention further relates to the use of such a lifting device.

Ein Teleskoprohr oder -zylinder der oben beschriebenen Art ist aus der US 4,875,660 A bzw. der EP 0 326 910 B1 bekannt und wird unter der Bezeichnung "SpiraLift" von der Firma PACO SPIRALIFT INC., Québec, Kanada vertrieben. Dieses rein mechanische Teleskoprohr ist gegenüber herkömmlichen pneumatischen oder hydraulischen Teleskopvorrichtungen insofern von Vorteil, als es für einen gegebenen Hub eine minimale Bauhöhe aufweist. Bei einem solchen Spirallift-Hubelement sind die Hubkraft und die Stromaufnahme zudem über den gesamten Hub konstant. Zudem ist das Hubelement nahezu wartungsfrei und kann im Nothandbetrieb mit einem Adapter von Hand verstellt werden.A telescopic tube or cylinder of the type described above is known from US 4,875,660 A or the EP 0 326 910 B1 and is sold under the name "SpiraLift" by PACO SPIRALIFT INC., Quebec, Canada. This purely mechanical telescopic tube is advantageous over conventional pneumatic or hydraulic telescopic devices in that it has a minimum height for a given stroke. In such a spiral lift lifting element, the lifting force and the current consumption are also constant over the entire stroke. In addition, the lifting element is virtually maintenance-free and can be adjusted by hand in emergency operation with an adapter.

Die US 6,382,358 B1 beschreibt eine Sicherungsvorrichtung für eine Hubvorrichtung.The US 6,382,358 B1 describes a safety device for a lifting device.

Aufgabe der Erfindung ist es somit, die Betriebssicherheit von Hubeinrichtungen gemäß dem Oberbegriff zu erhöhen.The object of the invention is thus to increase the reliability of lifting devices according to the preamble.

Diese Aufgabe wird bei einer Hubvorrichtung gemäß dem Oberbegriff erfindungsgemäß dadurch gelöst, daß die Hubvorrichtung Mittel zum Verhindern eines Abstürzens bei einem Versagen des Teleskoprohrs oder -zylinders aufweist, die eine Zahnstange und eine wellenförmige Profilbahn, die beide an einem festen Teil der Hubvorrichtung befestigt sind und eine an einem vertikal beweglichen Teil der Hubvorrichtung drehbar gelagerte Sperrklinke mit einer Rolle aufweisen, wobei Mittel zum Andrücken der Rolle gegen die Profilbahn vorgesehen sind und die Sperrklinke zum Eingriff in die Zahnstange ausgebildet ist.This object is achieved in a lifting device according to the preamble according to the invention in that the lifting device comprises means for preventing a crash in a failure of the telescopic tube or cylinder having a rack and a wave-shaped profile track, both of which are fixed to a fixed part of the lifting device and a rotatably mounted on a vertically movable part of the lifting device pawl having a roller, wherein means for pressing the roller against the Profile track are provided and the pawl is designed to engage in the rack.

Der Erfindung liegt die Erkenntnis zugrunde, daß auch bei einer Hubvorrichtung, die unter Verwendung derartiger Teleskoprohre oder -zylinder arbeitet, ein Abstürzen der Hubvorrichtung aufgrund eines technischen Versagens des Teleskoprohrs oder -zylinders möglich ist, z.B. bei Überschreiten der zulässigen Höchstlast. Um eine maximale Betriebssicherheit zu erreichen, werden die erfindungsgemäßen Mittel zum Verhindern eines Abstürzens bei einem Versagen des Teleskoprohrs oder -zylinders vorgesehen.The invention is based on the finding that even with a lifting device which operates using such telescopic tubes or cylinders, a crash of the lifting device due to a technical failure of the telescopic tube or cylinder is possible, for example when exceeding the maximum allowable load. To a maximum To achieve operational safety, the inventive means for preventing a crash in case of failure of the telescopic tube or cylinder are provided.

Im Normalbetrieb liegt die Rolle immer an der Profilbahn an, wodurch sichergestellt ist , daß die Sperrklinke nicht in die Zahnstange einrastet. Bei Überschreiten einer vorbestimmbaren vertikalen Geschwindigkeit, beispielsweise der Nennhubgeschwindigkeit, hebt die Rolle von der Profilbahn ab und die Sperrklinke rastet in die Zahnstange ein. Die Geschwindigkeit, bei der die Rolle von der Profilbahn abhebt, kann durch die Ausgestaltung der Profilbahn und den Anpreßdruck der Rolle variiert werden.In normal operation, the role is always on the profile web, which ensures that the pawl does not engage in the rack. When a predeterminable vertical speed, for example the rated stroke speed, is exceeded, the roller lifts off the profile track and the pawl engages in the rack. The speed at which the role of the profile web lifts, can be varied by the configuration of the profile sheet and the contact pressure of the role.

Eine alternative Ausgestaltung der Erfindung besteht darin, daß die Mittel zum Verhindern des Abstürzens eine Zahnstange und eine wellenförmige Profilbahn, die beide an einem vertikal beweglichen Teil der Hubvorrichtung befestigt sind und eine an einem festen Teil der Hubvorrichtung drehbar gelagerte Sperrklinke mit einer Rolle aufweist, wobei Mittel zum Andrücken der Rolle gegen die Profilbahn vorgesehen sind und die Sperrklinke zum Eingriff in die Zahnstange ausgebildet ist.An alternative embodiment of the invention is that the means for preventing the crash of a rack and a wave-shaped profile track, both of which are attached to a vertically movable part of the lifting device and having a rotatably mounted on a fixed part of the lifting device pawl with a roller Means are provided for pressing the roller against the profiled track and the pawl is designed to engage in the rack.

Diese Lösung stellt die kinematische Umkehr der ersten Lösung dar.This solution represents the kinematic reversal of the first solution.

Im Rahmen der Erfindung kann vorgesehen sein, daß die Mittel zum Andrücken der Rolle gegen die Profilbahn als Gegengewicht ausgebildet sind.In the context of the invention can be provided that the means for pressing the roller against the profiled sheet are designed as a counterweight.

Durch die Masse und den Hebel des Gegengewichtes wird der Anpreßdruck, der auf die Rolle wirkt, definiert und kann durch Veränderung dieser Parameter variiert werden.By the mass and the lever of the counterweight, the contact pressure acting on the roller is defined and can be varied by changing these parameters.

Ebenso ist es möglich, daß die Mittel zum Andrücken der Rolle gegen die Profilbahn als Feder ausgebildet sind.It is also possible that the means for pressing the roller against the profiled sheet are formed as a spring.

In diesem Zusammenhang ist es vorteilhaft, daß die Federkraft der Feder einstellbar ist.In this context, it is advantageous that the spring force of the spring is adjustable.

Dann kann durch Einstellen der Federkraft der Anpreßdruck der Rolle und somit die Auslösegeschwindigkeit der Absturzvorrichtung vorbestimmt werden.Then, by adjusting the spring force of the contact pressure of the roller and thus the release speed of the crash device can be predetermined.

Im Rahmen der Erfindung liegt auch die Verwendung einer erfindungsgemäßen Hubvorrichtung in der Automobilindustrie, insbesondere für den Fahrwerkeinbau.In the context of the invention is also the use of a lifting device according to the invention in the automotive industry, in particular for the chassis installation.

Im Fahrwerkeinbau (auch "Hochzeit" genannt) fügt man die Antriebs- und Fahrwerkkomponenten durch das Anheben des Werkstückträgers zur Karosse. Viele Montage- und Schraubprozesse, ob manuell oder automatisch, erfolgen nach dem Fügen von unten. Der Raum unterhalb des Werkstückträgers wird für Hubelemente und Montageprozesse (Schrauben, Clipsen, etc.) benötigt. Je kleiner die von der Hubvorrichtung benötigte Fläche ist, desto größer ist die nutzbare Fläche für die Zugänglichkeit der Montage-und Schraubwerkzeuge. Insofern ist die erfindungsgemäße Hubvorrichtung besonders für diese Einsatzgebiete geeignet.In chassis installation (also called "wedding"), the drive and chassis components are added by lifting the workpiece carrier to the body. Many assembly and screwing processes, whether manual or automatic, take place after joining from below. The space below the workpiece carrier is required for lifting elements and assembly processes (screws, clips, etc.). The smaller the area required by the lifting device, the greater the usable area for the accessibility of the assembly and screwing tools. In this respect, the lifting device according to the invention is particularly suitable for these applications.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand von Zeichnungen näher erläutert.An embodiment of the invention will be explained in more detail with reference to drawings.

Wie aus den Fig. 1a bis 1c ersichtlich, weist die erfindungsgemäße Hubvorrichtung 1 einen Grundrahmen 2 auf. In diesem sind die Mittel 3, um ein erstes Band spiralförmig transversal orthogonal um eine Mittelachse anzuordnen und ein zweites Band um sich selbst gewickelt anzuordnen, wobei die Windungen des zweiten Bandes zur Mittelachse transversal parallel liegen, und um , das erste Band in eine eingezogen gestapelte Stellung und das zweite Band in eine eingezogene spiralförmige Stellung zu überführen, angeordnet.Like from the Fig. 1a to 1c can be seen, the lifting device 1 according to the invention on a base frame 2. In this, means 3 are for arranging a first band spirally transversely orthogonal about a central axis and arranging a second band wound around itself, with the turns of the second band being transversally parallel to the central axis, and the first band being stacked in a retracted one Position and transfer the second band in a retracted helical position, arranged.

Die Hubvorrichtung 1, die im vorliegenden Fall zweistufig ausgebildet ist, weist zwei Mittel zum Verhindern des Abstürzens bei einem Versagen der Hubvorrichtung auf. Diese umfassen jeweils eine vertikal mitfahrende Zahnstange 4, eine ebenfalls vertikal mitfahrende Profilbahn 5, welche ein wellenförmiges Profil aufweist, und eine drehbar gelagerte, am festen Teil der Hubvorrichtung 1 befestigte Sperrklinke 6 mit einer Rolle 7 und einem Gegengewicht 8. Die Zahnstange 4 und die Profilbahn 5 verlaufen nebeneinander.The lifting device 1, which is formed in two stages in the present case, has two means for preventing the crash in case of failure of the lifting device. These each include a vertically moving rack 4, a likewise vertically moving profile track 5, which has a wave-shaped profile, and a rotatably mounted, fixed to the fixed part of the lifting device 1 pawl 6 with a roller 7 and a counterweight 8. The rack 4 and Profile track 5 run side by side.

Wie aus den Fig. 2a, 2b, 2c und 3 hervorgeht, funktionieren die Mittel 3 zum Verhindern des Abstürzens wie folgt. Die an der Sperrklinke 6 befestigte Rolle 7 wird durch das Gegengewicht 8 (welches auch durch eine Feder ersetzt werden könnte) gegen die Profilbahn 5 gedrückt und liegt auch beim Verfahren im Normalbetrieb immer an der Profilbahn 5 an.Like from the Fig. 2a, 2b, 2c and 3 As will be apparent, the means 3 for preventing the crash function as follows. The attached to the pawl 6 roller 7 is pressed by the counterweight 8 (which could also be replaced by a spring) against the profile web 5 and is always in the process in normal operation always on the profile web 5 at.

Erst wenn eine bestimmte, durch den Anpreßdruck definierte Geschwindigkeit überschritten wird, hebt die Rolle 7 von der Profilbahn 5 ab und die Sperrklinke 6 rastet in die Zahnstange 4 ein und blockiert die Hubvorrichtung 1. Der Anpreßdruck kann durch die Masse des Gegengewichtes 8 und den Hebel desselben auf ein gewünschtes Maß eingestellt werden, so daß die Mittel 3 zum Verhindern des Abstürzens erst bei Überschreiten der Normalgeschwindigkeit der Hubvorrichtung 1 auslösen.Only when a certain, defined by the contact pressure speed is exceeded, the roller 7 lifts off from the profile web 5 and the pawl 6 engages the rack 4 and blocks the lifting device 1. The contact pressure can by the mass of the counterweight 8 and the lever be set to a desired level, so that the means 3 for preventing the crash only when the normal speed of the lifting device 1 is exceeded.

Diese Absturzsicherung funktioniert rein mechanisch und bedarf keiner aufwendigen elektrischen oder pneumatischen Antriebselemente.This fall protection works purely mechanically and requires no expensive electrical or pneumatic drive elements.
