Die Erfindung kann auch genutzt werden, um vor Ort Bauteile ohne manuellen Kraftaufwand zur Erleichterung des Einbaus anzuheben.The invention relates to a lifting device for lifting and transporting loads. It is designed for parts that have a high weight and upwards a flat spatial extent, such as stone slabs, kitchen worktops, glass plates, etc. By means of a lifting device, heavy and unwieldy objects can be transported and lifted after transport. Thus, e.g. smaller distances between a transport vehicle and a construction site are overcome. The invention can also be used to locally increase components without manual effort to facilitate installation.
Die Vorrichtung besitzt zwei Achsen, an denen Räder mit Luft befüllten Reifen (Zeichnung B 7) angebracht sind. Die Achsen sind durch eine Brücke bestehend aus einem Stahl-, Holz- oder aus einem anderen haltbaren Material bestehenden Träger mittig verbunden (horizontal). Senkrecht auf die Brücke (vertikal) ist eine Linearachse (Zeichnung B 1) z.B. mit einer Schiebevorrichtung wie ein integrierter Spindeltrieb - (Zeichnung B 2) aufgestellt. Diese Achse befindet sich vorzugsweise im Schwerpunkt des Fahrzeugs. Um diese Achse sind Lastaufhahmeflächen angebracht (Zeichnung B 4), die mittels eines Hebemechanismus z.B. mittels des Kugelgewindetriebs angehoben werden. Der Hebemechanismus kann z.B. von einem Elektromotor (Zeichnung B 5) mittels eines zwischengeschalteten Getriebes (Zeichnung B 6) angetrieben. Die Lastaufnahmeflächen haben U-Profile, in die die zu transportierenden bzw, anzuhebenden Lasten parallel zur Linearachse auf der Lastaufnahmefläche - also vertikal - gelagert werden. Diese Anordnung ermöglicht es, Steinplatten, Küchenarbeitsplatten und andere schwere unhandliche Gegenstände mit einer geringen Höhe aber großen seitlichen Ausmaßen aufzunehmen und manuell durch verschieben dieses Fahrgestells zu bewegen. Die mit Luft befüllten Räder ermöglichen das Überwinden von Unebenheiten wie Schwellen und kleinere Stufen. Am Bestimmungsort angekommen, kann der transportierte Gegenstand durch die Betätigung einer nachfolgend beschrieben Steuerflasche angehoben werden. Die am Gerät angebrachten Endschalter verhindern ein Verfahren des Antriebs über die Endposition hinaus.The device has two axles to which wheels with air-filled tires (drawing B 7) are attached. The axles are connected by a bridge consisting of a steel, wood or other durable material carrier centered (horizontal). Perpendicular to the bridge (vertical) is a linear axis (drawing B 1) e.g. with a pusher as an integrated spindle drive - (drawing B 2) set up.

Das Fahrgestell ist aus Stahlprofilen der Qualität S235 J2G3 gefertigt. Jedoch bestehen aus statisch-konstruktiver Hinsicht in Zukunft keine Bedenken gegen eine Ausführung aus hochfestem Aluminium AlZn4,5Mgl.The chassis is made of steel profiles of quality S235 J2G3. However, from a static-constructive point of view, there are no future objections to a design made of high-strength aluminum AlZn4,5Mgl.
Die vier Räder am Fahrgestell sind als Luftreifen ausgeführt, was speziell beim Transport über Schwellen erhebliche Vorteile bringt.The four wheels on the chassis are designed as pneumatic tires, which brings significant advantages especially when transporting over thresholds.
Die Lastaufnahme ist aus Baustahl der Qualität S235 J2G3 ausgeführt. Die Last wird von einem U-Profil aufgenommen und kann z.B. auf die Kugelgewindemutter übertragen werden. Die Lastaufnahme wird im Galgen des Fahrgestells geführt wodurch die Momentenbelastung abgetragen wird. Die Vertikallast wird auf die Spindel übertragen.The load suspension is made of structural steel of quality S235 J2G3. The load is taken up by a U-profile and can e.g. be transferred to the ball screw nut. The load is taken in the gallows of the chassis whereby the moment load is removed. The vertical load is transmitted to the spindle.
An der Lastaufnahme ist eine Arretierungsmöglichkeit vorhanden welche von oben auf das zu bewegende Teil geschoben und fixiert wird. Diese Vorrichtung verhindert ein zur Seite wegkippen des TransportteilsAt the load receiving a locking possibility is present which is pushed from above onto the part to be moved and fixed. This device prevents tilting away to the side of the transport part
Die Spindel wird von einem 24 V Gleichstrom-Elektromotor angetrieben.The spindle is powered by a 24 V DC electric motor.
Dem Motor ist ein Getriebe der Übersetzung 1:10 nachgeschaltet welches das benötigte Drehmoment sowie die benötigte Drehzahl wandelt.The engine is followed by a gear ratio of 1:10, which converts the required torque and the required speed.
Am Motor ist eine Bremse angeflanscht welche erst durch betätigen der Steuerflasche geöffnet wird. Die Bremse verhindert ein Herabsinken des Transportteils in nicht betätigtem Zustand. Es liegt somit eine Selbsthemmung vor.A brake is flanged on the engine which is only opened by pressing the control bottle. The brake prevents a lowering of the transport part in the non-actuated state. There is thus a self-locking.
Die Kraftübertragung erfolgt über eine Passfederverbindung zwischen der Hohlwelle des Getriebes sowie der Kugelgewindespindel.The power transmission takes place via a keyway connection between the hollow shaft of the transmission and the ball screw spindle.
Der Linearantrieb besteht aus einer Kugelgewindespindel 25×10 mit einer entsprechenden Kugelgewindemutter. Die Länge der Spindel beträgt 1192mm.The linear drive consists of a ball screw 25 × 10 with a corresponding ball screw nut. The length of the spindle is 1192mm.
Die Vertikal- und Horizontalkräfte am unteren Ende der Spindel werden von einem Kegelrollenlager aufgenommen. Am oberen Spindelende werden die dort auftretenden Horizontalkräfte von einem Gleitlager übertragen.The vertical and horizontal forces at the lower end of the spindle are absorbed by a tapered roller bearing. At the upper end of the spindle, the horizontal forces occurring there are transmitted by a plain bearing.
Das Anheben und Senken der Last erfolgt über eine Steuerflasche die über ein Kabel mit der Steuerung verbunden ist.The lifting and lowering of the load takes place via a control bottle which is connected to the control via a cable.
Das Gerät ist mit induktiven Endschaltern ausgestattet welche die Bewegung in den Endpositionen stoppen. Des Weiteren befindet sich an der Steuerflasche ein Not-Aus-Knopf welcher nach betätigen alle Bewegungen stoppt.The device is equipped with inductive limit switches which stop the movement in the end positions. Furthermore, there is an emergency stop button on the control bottle which stops all movements when pressed.
Das Gerät wird durch zwei in Reihe geschalteter 12 V Bleigelakkus mit Energie versorgt.The unit is powered by two 12V lead gel batteries connected in series.
