Description
Hublader mit Steinklemmgabel Die Erfindung betrifft einen Hublader mit Steinklemmgabel mit hydraulisch arbeitenden Klemmpressen und Kolbenrückholfeder. Für derartige Hublader sind Tragzinken entwickelt worden, die I-föniügen, U-förmigen oder kastenförmigen Querschnitt aufweisen und die Klemmpressen enthalten. Die Kosten dieser Tragzinken sind wegen der Sonderanfertigung verhältnismäßig hoch.Lift truck with stone clamping fork The invention relates to a lift truck with stone clamping fork with hydraulic clamping presses and piston return spring. Carrying tines have been developed for such lifters that are I-shaped, U-shaped or box-shaped cross-section and contain the clamping presses. The costs these tines are relatively high because of the custom-made product.
Der Erfindung liegt die Aufgabe zugrunde, einen Hublader mit Steinklemmgabel zu schaffen, deren hydraulische Pressen ohne weiteres an den bekannten Hublade,r-Tragzinken mit Rechteckquerschnitt befestigt werden können, und zwar derart, daß die unter benachbarten Zinken liegenden, einander zugekehrten Klemmpressen auf derselben Achse liegen und so ein Kippen des gemeinsam erfaßten Steines ausschließen.The invention is based on the object of a lift truck with a stone clamping fork to create their hydraulic presses without further ado to the well-known lifting drawer, r-carrying prongs can be attached with a rectangular cross-section, in such a way that the under adjacent prongs, facing clamping presses on the same axis lie and thus exclude tilting of the jointly grasped stone.
Die Erfindung setzt somit einen Hublader mit Steinklemmgabel voraus, deren hydraulische, an die Tragzinken angebaute, wechselweise nach entgegengesetzten Seiten einer Tragzinke gerichtete Klemmpressen mit Kolbenrückholfeder ausgerüstet und durch einen gemeinsamen Druckmittelzufuhrkanal mtieinander verbunden sind.The invention therefore requires a lift truck with a stone clamping fork, their hydraulic, attached to the carrying tines, alternately in opposite directions Clamping presses directed towards the sides of a support prong are equipped with a piston return spring and are connected to one another by a common pressure medium supply channel.
Die Lösung der Aufgabe besteht darin, daß je- weils mindestens zwei Klemmpressen mit parallelliegenden Kolbenachsen zu einem außen an dem massiven Tragzinken befestigten Block vereinigt sind, durch den der Druckmittelzufuhrkanal hindurchgeführt ist. Diese Konstruktion ermöglicht es, Blöcke für alle Hublader mit Steinklemmgabel in ein und derselben Ausführung herzustellen, ohne daß die Lage gegenüberliegender Klemmpressen auf der gleichen Achse verlassen werden muß.The solution to the problem is that in each case at least two clamping presses with parallel piston axes are combined to form a block which is fastened on the outside of the solid support prongs and through which the pressure medium supply channel is passed. This construction makes it possible to manufacture blocks for all lifters with stone clamping fork in one and the same design without having to leave the position of opposing clamping presses on the same axis.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt A b b. 1 einen Längsschnitt durch einen Formsteinstapel unmittelbar neben der Tragzinke, A b b. 2 einen Querschnitt durch Tragzinke und daran befestigtem Block, Ab b. 3 eine Draufsicht auf einen unter einer Tragzinke angeschraubten Block.An exemplary embodiment of the invention is shown in the drawing. It shows A b b. 1 shows a longitudinal section through a stack of shaped stones directly next to the support prong, A b b. 2 shows a cross-section through the support prong and the block attached to it, from b. 3 shows a plan view of a block screwed on under a support prong.
An der oberen Quertraverse 1 des Hubschlittens 2 eines Hubladers ist eine normale Tragzinke 3 eingehängt, an der unten die Blöcke 4 mittels versenkter Innensechskantschrauben 5 festgeschraubt sind. Die Blöcke 4, bestehend aus den einzelnen Blöcken 4', 4" und 4"', sind durch Druckmittelrohre 6 miteinander verbunden; der Endblock 4' hat einen nach vorn durch einen Stopfen 8 verschlossenen Druckmittelkanal 7 und der erste Block 4" eine Verbindungsleitung 9 zum hydraulischen System des Fahrzeugs. Der das Druckmittel durch den Block hindurchführende Druckmittelkanal 7 ist durch die Enden der Klen-impressenzylinder 10 hindurchgelegt, so daß der im Druckmittelsystem herrschende Druck die Klemmpressen 11 beaufschlagen kann. A normal support prong 3 is attached to the upper cross member 1 of the lifting carriage 2 of a lift truck, to which the blocks 4 are screwed by means of countersunk Allen screws 5 at the bottom. The blocks 4, consisting of the individual blocks 4 ', 4 "and 4"', are connected to one another by pressure medium pipes 6; the end block 4 'has a forwardly closed by a plug 8 pressure fluid channel 7 and the first block 4, "a connection line 9 to the hydraulic system of the vehicle. The the pressure medium leading through the block fluid passage 7 is passed down impressenzylinder Klen-through ends 10, so that the pressure prevailing in the pressure medium system can act on the clamping presses 11 .
Da die Ober- und Unterhälften der Blöcke 4 - wie aus Ab b. 2 ersichtlich - gleich sind und die Anordnung der Klemmpressen 11 im Block 4 derart ist, daß die Seitenansicht des Blocks nach Drehung um die vertikale Mittelachse des Blocks um 180' das gleiche Bild ergibt, benötigt man nur Blöcke derselben Form und kann sie nach Erfordernis derartig versetzt anordnen, daß gegenüberliegende Klemmpressen benachbarter Tragzinken auf derselben Achse liegen. Die von den Klemmpressen erfaßten Steine 13 werden dann kippfrei geklemmt.Since the upper and lower halves of blocks 4 - as shown in Fig. B. 2 can be seen - are the same and the arrangement of the clamping presses 11 in block 4 is such that the side view of the block after rotation about the vertical center axis of the block by 180 ' gives the same picture, you only need blocks of the same shape and they can as required staggered arrange that opposite clamping presses of adjacent support prongs are on the same axis. The stones 13 gripped by the clamping presses are then clamped without tilting.
An dem Kolben der Klemmpresse 11 ist ein Teller 11' zur Befestigung für ein am Stein 13 anliegendes Schleißstück 12 und für einen Ring 14 angebracht, der eine Federhülse 15 an der Klemmpresse befestigt. Durch die Federhülse 15 wird die Verwendung einer Druckfeder 16 zum Zurückziehen der Klemmpresse ermöglicht und außerdem die Gleitfläche der Klemmpresse im ausgefahrenen Zustand vor der Einwirkung von Staub, Feuchtigkeit und mechanischem Angriff weitgehend geschützt.A plate 11 ' is attached to the piston of the clamping press 11 for attachment of a wear piece 12 resting on the stone 13 and for a ring 14 which attaches a spring sleeve 15 to the clamping press. The spring sleeve 15 enables the use of a compression spring 16 to retract the clamping press and also largely protects the sliding surface of the clamping press in the extended state from the effects of dust, moisture and mechanical attack.
Somit können normale Tragzinken jederzeit mit Blöcken 4 bestückt werden und dann für den Transport von Formsteinstapeln ohne Paletten benutzt werden. Da die Verbindung nur aus den Schrauben 5 und den hydraulischen Anschlüssen 6 und 9 besteht, ist sie jederzeit einfach und schnell herzustellen oder zu lösen. Der Aufwand für die Einrichtung ist gering und die Lagerhaltung einfach.This means that normal carrying tines can be fitted with blocks 4 at any time and then used for the transport of stacks of shaped blocks without pallets. Since the connection consists only of the screws 5 and the hydraulic connections 6 and 9 , it can be easily and quickly established or released at any time. The set-up effort is low and storage is easy.
