Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Einrichtung zum Heben von Lasten mittels Nürnberger Schere. Sie besteht darin, daß auf einer gemeinsamen Antriebsachse zwei Exzenterscheiben mit entgegengesetzt gerichteter Exzentrizität angeordnet sind, die bei einer Drehung das unterste Scherenglied nach oben und unten spreizen. In der Zeichnung ist diese Vorrichtung beispielsweise an einem Aufzuge schematisch dargestellt. The invention relates to a device for lifting loads using Nuremberg scissors. It consists in the fact that two eccentric discs with opposite sides on a common drive axle directed eccentricity are arranged, which spread the lowermost scissor link up and down when rotated. In the drawing, this device is shown schematically on an elevator, for example.

Der Aufzug besteht aus den Scherengliedern a, O1, die mit der Plattform b gelenkig verbunden sind. Die Scherenglieder sind in einem Kasten (Wagenkasten) eingebaut und mit ihren Gelenkbolzen in Führungen geführt, welch letztere gegebenenfalls an Ort und Stelle entsprechend aufgebaut bzw. verlängert werden. Das unterste Scherenglied ist mit zwei Querstreben c, d versehen, zwischen denen die Achse f der Exzenterscheiben g, g gelagert • ist. Diese kann von Hand oder maschinell in Drehung versetzt werden. Die Exzenterscheiben sind auf ihrer Achse in der Weise angeordnet, daß ihre Exzentrizität einander entgegengerichtet ist. An der unteren Querstrebe d sind Gegengewichte h, h angehängt, die dem Gewichte der Scherenglieder genau oder nahezu entsprechen, um die Exzenterscheiben möglichst zu entlasten.The elevator consists of the scissor links a, O 1 , which are articulated to the platform b. The scissor links are installed in a box (car body) and guided with their hinge pins in guides, the latter being built up or lengthened accordingly on site if necessary. The lowermost scissor link is provided with two cross struts c, d , between which the axis f of the eccentric disks g, g is mounted. This can be turned by hand or by machine. The eccentric disks are arranged on their axis in such a way that their eccentricity is opposite to one another. Counterweights h, h are attached to the lower cross strut d , which correspond exactly or almost to the weights of the scissor links in order to relieve the eccentric disks as much as possible.

Die Exzenterscheiben g, g liegen an den Querstreben c, d an und drängen diese bei einer Drehung der Welle f auseinander, so daß sie das unterste Scherenglied nach oben und nach unten hin auseinanderspreizen. Durch diese Spreizung werden die übrigen Glieder der Schere gestreckt, und es wird so die mit ihnen verbundene Plattform der Last gehoben. Das Senken der Plattform erfolgt dadurch, daß die Exzenterscheiben über ihre senkrechte Stellung hinausgedreht werden.The eccentric disks g, g rest on the cross struts c, d and urge them apart when the shaft f rotates so that they spread the lowermost scissor link up and down. Through this spreading, the remaining links of the scissors are stretched and the load platform connected to them is raised. The platform is lowered by turning the eccentric disks beyond their vertical position.

Diese Vorrichtung kann ortsfest oder beweglich in einem Wagen eingebaut sein.This device can be installed in a stationary or movable manner in a car.
