Description

Die Erfindung betrifft eine Abraumförder- brücke.hei der der haldenseitige frei tragende Brückenausleger mit einer in einer waage- recht-en Ebene schwenkbaren Auslegerspitze versehen ist, die durch je ein Gelenk ain Ober- und Untergurt des Brückenauslegers allgelenkt ist. Es ist ein Abraumfördergerät bekannt, bei dem das Degengewicht eines auf dem Gerät aufgestellten Dr°likranes als Gegengecc-ichts- ausgleich für einen Langförderer dient. wenn der Drehkran mit dem Langförderer gekop- pelt ist und das Gegengewicht des Drehkranes dem Langförderer gegenüberliegt. Hierbei drehen sich Drehkran und Langförderer mit der gleichen Winkelgeschwindigkeit. Demgegenüber kennzeichnet sich die Ir- hndung dadurch. daß zur Erzielung eines möglichst kleinen Gegenge@viclit@es der Gegeil- gewichtsarm des Auslegerteils durch Einschaltun,- ein: s entsprechenden Lfii#ersetzungsgetrielies einen größeren Winkel- ausschlag beschreibt als der schwenkbare Auslegerteil. In der Zeichnung ist das Wesen der Er- findung in den Ablz.I und 2 im Auf- und Grundriß veranschaulicht. Der rückwär- tige-. das Gegengewicht 1d. tragende Arm 13 ist mit crem schwenkbaren Auslegerteil io nicht fest. sondern durch eine in gleicher Mitte mit dem Gelenkpunkt io liegende .@clise I j drehbar verbunden. lein Antrieb erfolgt von einem mit dem schwenkbaren Teil io fest verbundenen Zahnrad i(. (las ein zu einem Doppelrad gehörendes Kitzel I; treibt, dessen zweites Rad IS in ein Zahnrad i9 eingreift. das mit dein Gegengewichtsarm 13 fest ver- bunden ist. Das Doppelrad I;. I8, ist lose drehbar auf einem Zapfen 20 gelagert. der mit dein festen @@uslegerte'il 9 <ler frei tragen- den Abraumförderbrücke verbunden ist. Durch entsprechende Wahl der L"l,>ersetzuii" wird erzielt, daß der trczengewicht:arm i3 in der Endstellung des schwenkbaren Ausle-er- teils ICI. die nacli Abli. 2 "l_. 1i. et,%'a 22^ be- trägt, einen Weg von c)o- -zurückgelegt hat. Das Gegengewicht kann s(:mit bei dieser All- ordnung bei aleichbl-°iliender Ausladung kleiner ausfallen, als wenn es wie üblich den gleichen Ausschlag wie der schtcenl;bar: Atis- legerteil ausführt. The invention relates to an overburden conveyor bridge. is called the cantilevered one on the dump side Bridge jib with a horizontal right-hand level swiveling boom tip is provided, which ain each by a joint Upper and lower chord of the bridge jib is all-steered. It is known a spoil conveyor at the epee weight of one on the device set up Dr ° likranes as a counter-face-to-face is used to compensate for a long conveyor. if the slewing crane is coupled with the long conveyor pelt and the counterweight of the slewing crane opposite the long conveyor. Here The slewing crane and long conveyor turn with it the same angular velocity. In contrast, the Ir- result of this. that to achieve a the smallest possible counterpart @ viclit @ it is the opposite low weight des Boom part by switching on, - a: s corresponding Lfii # replacement getrielies a larger angle rash describes as the pivotable Boom part. In the drawing, the essence of the found in sections I and 2 in the and floor plan illustrated. The reverse good-. the counterweight 1d. supporting arm 13 is io with cream swiveling boom part not fixed. but through one in the same In the middle with the hinge point io. @ Clise I j rotatably connected. There is no drive of one with the swiveling part io fixed connected gear i (. (read a to a Tickle I belonging to the double wheel; drives whose second wheel IS meshes with a gear i9. that is firmly connected to your counterweight arm 13 is bound. The double wheel I ;. I8, is loose rotatably mounted on a pin 20. the with your fixed @@ uslegerte'il 9 <ler freely carry- the overburden conveyor bridge is connected. By choosing the L "l,>ersetzuii" it is achieved that the weight: arm i3 in the end position of the swiveling boom partly ICI. the nacli abli. 2 "l_. 1i. Et,% 'a 22 ^ be carries, has traveled a distance from c) o-. The counterweight can s (: with this all- order with evenly bladed projection turn out smaller than if it were the usual same rash as the schtcenl; bar: Atis- casual part executes.
