Description

Hubtransportwagen Bei Hubtransportwagen, deren hebbare Plattformen durch einfache Verbindungslaschen mit dem Wagengestell gelenkig verbunden sind, ist es bekannt, die Hubvorrichtung mittels einfacher Zugstangen an der Plattform angreifen zu lassen. Die Erfindung bezieht sich auf eine andere Bauart von Hubtransportwagen für größere Lasten, bei denen die Plattform mittels am Wagengestell drehbar gelagerter Winkelhebel heb- und senkbar ist. Während bisher zwischen der Hubvorrichtung und den erwähnten Winkelhebeln vorgesehene Kraftübertragungsorgane am Wagengestell gelagert waren, sind diese Übertragungsorgane erfindungsgemäß an der Plattform selbst gelagert. Hierdurch wird eine bessere Ausnutzung der Hubkraft erzielt, und die einzelnen Bauteile können schwächer gehalten werden.Lifting trolleys With lifting trolleys, their liftable platforms are articulated to the trolley frame by simple connecting straps, it is known, the lifting device by means of simple tie rods on the platform to attack. The invention relates to another type of lift truck for larger loads where the platform is rotatably mounted on the carriage frame Angle lever can be raised and lowered. While so far between the lifting device and the aforementioned angle levers provided power transmission members mounted on the carriage frame were, according to the invention, these transmission organs are mounted on the platform itself. This makes better use of the lifting force and the individual components can be kept weaker.

Ein Ausführungsbeispiel der Erfindung, bei dem als Übertragungsorgane Winkelhebel dienen, ist in der Zeichnung dargestellt. Abb. I zeigt einen Hubtransportwagen von der Seite gesehen, während Abb. 2 sein vorderes Ende von oben gesehen unter Weglassung eines Gestellteiles veranschaulicht.An embodiment of the invention, in which as transmission organs Serve angle lever is shown in the drawing. Fig. I shows a lift truck seen from the side, while Fig. 2 has its front end seen from above below Omission of a frame part illustrated.

Die Plattform I ist durch die Träger 2 mit den kurzen Hebeln 3 gelenkig verbunden, die auf den im Wagengestell 4 gelagerten Wellen 5 sitzen. Die Wellen 5 tragen weitere Hebel 6, die durch Stangen 7 untereinander und durch Zugstangen 8 mit den Winkelhebeln 9 gelenkig verbunden sind. Die Winkelhebel 9 sind erfindungsgemäße an der Plattform I drehbar gelagert, z. B. mittels der Welle Io, die in Lageraugen II der Plattform I ruht. Die vorderen Arme der Winkelhebel 9 sind durch Laschen I2 mit einer auf der Kolbenstange I3 des hydraulischen Hebers I4 angeordneten Traverse I5 gelenkig verbunden. Die Kolbenstange I3 kann hierbei in einem Gestell I6 oben geführt sein.The platform I is articulated by the carrier 2 with the short levers 3 connected, which sit on the shafts 5 mounted in the carriage frame 4. The waves 5 carry more levers 6, which are supported by rods 7 with each other and by tie rods 8 are articulated to the angle levers 9. The angle levers 9 are according to the invention rotatably mounted on the platform I, for. B. by means of the shaft Io, which is in bearing eyes II of the platform I is resting. The front arms of the angle lever 9 are through tabs I2 with a traverse arranged on the piston rod I3 of the hydraulic jack I4 I5 articulated. The piston rod I3 can in this case in a frame I6 above be led.

Durch den Hub der Kolbenstange I3 werden mittels der Laschen I2 nicht nur die Winkelhebel 9 gedreht, sondern gleichzeitig wird auch die Welle Io hochgehoben. Die Hubkraft wird also zum Teil unmittelbar zum Heben der Plattform I ausgenutzt, was den weiteren Vorteil hat, daß die Lagerkräfte in den Wellen 5 und die Biegungsmomente in den Wagengestellträgern 4 geringer sind als bei den bekannten Bauarten. Da ferner der Weg der Welle Io (Winkelhebeldrehpunkt) die ganze Übersetzung ins Langsame vergrößert, so können die vorderen Arme der Winkelhebel 9, an denen die Laschen I2 angreifen, kurz gehalten werden, wodurch sich eine gedrängtere Bauart des Wagens ergibt.Due to the stroke of the piston rod I3, the lugs I2 do not only the angle lever 9 rotated, but at the same time the shaft Io is lifted up. The lifting force is therefore partly used directly to lift platform I, which has the further advantage that the bearing forces in the shafts 5 and the bending moments in the car frame supports 4 are less than in the known types. Since furthermore the path of the shaft Io (angle lever pivot point) increases the entire gear ratio to slow speed, so the front arms of the angle lever 9, on which the tabs I2 engage, be kept short, resulting in a more compact design of the car.

Die nur beispielsweise dargestellte Bauart kann in vielfacher Weise abgeändert werden. Die Winkelhebel 9 können in einzelne auf der Welle Io verkeilte Hebel getrennt werden. Die Zugstangen 7, 8 können aus einem Stück bestehen, in welchem Fall an ihren Verbindungsstellen mit den Winkelhebeln Langlöcher vorzusehen wären. Auch ist die erfindungsgemäße Anordnung des Drehpunktes eines Übertragungsgliedes (Winkelhebels) an der Plattform nicht auf die dargestellte Gestängeanordnung zum Heben und Senken der Plattform beschränkt. Ebenso kann an Stelle der hydraulischen Hubeinrichtung eine andere bekannte Hubvorrichtung treten.The type shown only as an example can be used in many ways be modified. The angle levers 9 can be wedged into individual ones on the shaft Io Levers are separated. The tie rods 7, 8 can consist of one piece in which Case would have to provide elongated holes at their connection points with the angle levers. The arrangement according to the invention is also the fulcrum of a transmission link (Angle lever) on the platform not to the linkage arrangement shown Limited lifting and lowering of the platform. Likewise, instead of the hydraulic Lifting device kick another known lifting device.
