Description

Scherenartige Hebevorrichtungen und scherenartig ausziehbare Haltevorrichtungen sind bekannt.Scissor-like lifting devices and scissor-like retractable holding devices are known.

Die Erfindung betrifft einen Scherenturm, dessen Neuheit darin besteht, daß vier Scheren im Viereck mittels Drehgelenkbolzen miteinander verbunden sind, so daß dieser nunmehr viereckige Turm ein Ganzes bildet und alle vier Schereneden auf vier über Kreuz angeordneten Spindelwellen aufruhen, wodurch diese gleichzeitig ein und dieselbe Bewegung ausführen.The invention relates to a scissor tower, the novelty of which is that four scissors are connected to each other in a square by means of swivel bolts, so that this now square tower forms a whole and all four scissors rest on four crossed spindle shafts, making them simultaneously perform one and the same movement.

Zur Schaffung einer Plattform auf dem Turm sind zwei über Kreuz angeordnete Schiebeschlitzschienen mit Rollen unter- wie oberhalb der Schienen miteinander verbunden und an den obersten Schereneden befestigt. Sie dienen dem Ausgleich der Scherenveränderungen. Auf dem Rahmen wiederum ist ein Kugeldrehkranz angeordnet, auf welchem das Förderhaus aufgebaut ist.To create a platform on the tower, two are arranged crosswise Slotted slotted rails connected to one another with rollers below and above the rails and attached to the top scissor ends. They serve to compensate for changes in the scissors. On the frame, in turn, a slewing ring is arranged on which the conveyor house is constructed.

Der Scherenturm hat gegenüber den bekannten Kränen den Vorteil, daß er innerhalb von wenigen Minuten auf- bzw. abgebaut und immer fahrbereit ist. Er ist ein Mehrzweckgerät, denn in heruntergedrehtem Zustand kann man ihn auch, mit einem Greifer versehen, als Bagger benutzen. Als kleinerer Typ mit Handwagenfahrgestell in der 'Größe2X2m eignet sich der Scherenturm als Baugerüst mit Aufzug; ferner ist er als Rettungsleiter und für Löschtürme der Feuerwehr verwendbar.The scissor tower has the advantage over the known cranes that it is set up or dismantled within a few minutes and is always ready to drive. He is a multi-purpose device, because when turned down you can also use it with provided with a grab, use it as an excavator. As a smaller type with a handcart chassis In the size 2X2m, the scissor tower is suitable as scaffolding with a lift; further is it can be used as a rescue ladder and for fire brigade extinguishing towers.

In der Zeichnung ist eine Seitenansicht des hochgedrehten Scherenturms dargestellt. Mit Ii bezeichnet ist das Untergestell. 2 sind über Kreuz angeordnete Spindelwellen. 3 sind Kugellagerschalen mit den Drucklagern 4. 5 ist ein Tellerrad, welches auf die in die Spindelwellen befestigten Kegelräder greift. 6 ist eine Kurbel mit Kegelrad. Durch Drehen an der Kurbel stellt sich der Scherenturm herauf bzw. herunter. 7 ist der scherenartige Turm, von dem acht Schereneden und je zwei Stück in den mit 8 bezeichneten Spindelschuhen drehbar befestigt sind. Alle Scherenenden sind mit Drehgelenkbolzen verbunden, wodurch seine absolute Stabilität erreicht wird. 9 sind über Kreuz angeordnete Schiebeschlitzschienen, in welchen die Scherenenden I0 mit ihren Unter- und Oberrollen II laufen. Diese Vorrichtung dient den Scherenveränderungen beim Herauf- und Herunterdrehen des Turms. Die Schiebeschlitzschienen dienen gleichzeitig als Unterboden für die Plattform. I2 ist der Kugeldrehkranz, welcher unter Freilassung der Oberrollen auf einem Sockel des Plattformrahmens montiert ist. I3 ist das auf dem Kugeldrehkranz montierte Förderhaus. I4 sind Drehgelenkbolzen, welche in Rotgußlagerbuchsen gelagert werden.In the drawing is a side view of the upturned scissor tower shown. The underframe is designated by Ii. 2 are arranged crosswise Spindle shafts. 3 are ball bearing shells with the thrust bearings 4. 5 is a crown wheel, which engages the bevel gears attached to the spindle shafts. 6 is a crank with bevel gear. Turn the crank to raise or lower the scissor tower. down. 7 is the scissor-like tower, of which eight scissors and two pieces each are rotatably mounted in the spindle shoes designated by 8. All scissor ends are connected with swivel pins, which gives it absolute stability will. 9 are cross-arranged sliding slot rails in which the scissor ends I0 run with their lower and upper rollers II. This device is used to change the scissors when turning the tower up and down. The sliding slot rails serve at the same time as a sub-floor for the platform. I2 is the slewing ring, which is released the top roller is mounted on a base of the platform frame. I3 is that on the conveyor house mounted on the slewing ring. I4 are swivel pins, which are in gunmetal bearing bushes be stored.
