KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft einen Kran zum Lösen und Abheben von Blockformen und zum Ausstoßen des Blockes; sie besteht darin, daß die Zange und der Ausdrückstempel federnd gelagert sind. Hierdurch wird nicht nur die Übertragung von Stößen auf das Getriebe vermieden, dieses daher geschont und nicht in dem Maße beansprucht wie bei unnachgiebiger Lagerung, sowie durch Fernhalten der Stöße vom Getriebe auch der Motor geschont, sondern es gewährt auch im besonderen die neue Einrichtung beim Blockfassen eine gewisse Sicherheit gegen das Herausfallen des Blockes, indem ein etwaiger Rückwärtsgang des Motors sich nicht unmittelbar auf die Zange überträgt und diese öffnet, sondern zunächst eine Entlastung der Federn bewirkt. Erst wenn der Rückgang einen bestimmten Betrag überschreitet, tritt ein öffnen der Zange ein.The invention relates to a crane for releasing and lifting block forms and to eject the block; it consists in the fact that the pliers and the ejector are resilient are stored. This not only prevents the transmission of shocks to the gearbox avoided, this is therefore spared and not stressed to the same extent as with unyielding storage, as well as keeping the shocks away from the gearbox and the engine spared, but it also grants in particular the new facility for block gripping a certain security against falling out of the block by a possible reverse gear of the motor is not transmitted directly to the clamp and opens it, but initially causes a relief of the springs. Only when the decline is a certain Exceeds the amount, the pliers will open.
Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung im Aufriß und teilweise im Schnitt schematisch dar.The drawing illustrates an embodiment of the invention in elevation and in part in section schematically.
Der Motor α überträgt seine Bewegung vermittels der Stirnräder b und der Kegelräder c auf eine Spindel d. Dadurch wird der Ausdrückstempel e, der am oberen Ende als Mutter ausgebildet ist und die Schraubenspindel d umgibt, auf oder ab bewegt. Bei der Aufwärtsbewegung wird durch Ansätze am unteren Ende des Stempels e die Zange f geschlossen. Die Zugkraft des Stempels e pflanzt sich durch den Zangenkopf g und die Stangen h auf den Teller i fort. Der Zug in der Spindel d wird auf das Kammlager k übertragen. Zwischen dem Teller i und dem Kammlager k sind Federn I eingebaut. Diese verhindern, daß beim Fassen des Blockes die lebendigen Kräfte plötzlich gehemmt werden, so daß Stöße nicht auftreten können. Beim Blockausdrücken wird der Stempel e abwärts bewegt. Hierbei erfüllen die Federn m, die die Stangen h mit dem Kammlager k elastisch verbinden, denselben Zweck wie beim Blockfassen die Federn I. '45The motor α transmits its movement to a spindle d by means of the spur gears b and the bevel gears c. As a result, the ejection punch e, which is designed as a nut at the upper end and surrounds the screw spindle d , is moved up or down. During the upward movement, the pliers f is closed by attachments at the lower end of the punch e. The tensile force of the punch e is propagated through the pliers head g and the rods h onto the plate i . The train in the spindle d is transferred to the cam bearing k . Springs I are installed between the plate i and the comb bearing k. These prevent the living forces from suddenly being inhibited when the block is grasped, so that shocks cannot occur. When printing in blocks, the stamp e is moved downwards. Here, the springs m, which elastically connect the rods h to the comb bearing k, fulfill the same purpose as when the springs I. '45 are gripped in blocks
Die Vorrichtung kann auch so ausgebildet werden, daß nur ein Federnpaar notwendig ist.The device can also be designed so that only one pair of springs is necessary.
