Abstract
Description
Titel der Erfindung:Title of the invention:
Verstopfungsfreie Leiteinrichtung für Schüttgüter, insbesondere an Verladeauslegern von Tagebaugroßgeräten Die Erfindung betrifft eine Leiteinrichtung zur Bördergutübergabe, insbesondere am Ende eines Verladeauslegers von Ta gebaugroß geräten.Blockage-free guide device for bulk goods, in particular on Loading booms for large open-cast mining equipment The invention relates to a Guide device for transferring goods, especially at the end of a loading arm of Ta built large appliances.
Bekannt sind Leiteinrichtungen und Schurren für Schüttgiiter als Rosenschurren mit schwenkbarer Verteilerklappe oder horizontal verschiebbare kastenförmige Sattelschurren oder schlauchförmige, durch Seste Mäntel umschlossene Leitschurren, durch deren Mitten die Schüttgüter geführt werden.Guiding devices and chutes for Schüttgiiter are known as rose chutes with swiveling distributor flap or horizontally slidable box-shaped saddle straps or tubular guide chutes enclosed by Seste coats, through their The bulk goods are guided in the middle.
Weiterhin sind seitliche Begrenzungsflächen aus elastischem oder starrem Material zur Führung von Pördergutströmen bekannt, deren Wirkung jedoch umstritten ist. Alle diese Einrichtungen haben den Nachteil, daß sie zu Verstopfungen neigen und daher das von den Begrenzungsflächen der Schurren markierte mögliche Verstopfungsvolumen aus dem jeweiligen Schüttgut vorschriftsgemäß als Zusatzbelastung in die statische Berechnung und den Standsicherheitsnachweis eines Ta gebaugroß gerätes eingerechnet werden muß.Furthermore, the lateral boundary surfaces are made of elastic or rigid Material for guiding flow of conveyed goods is known, but its effect is controversial is. All of these devices have the disadvantage that they are prone to clogging and therefore the possible clogging volume marked by the boundary surfaces of the chutes from the respective bulk material according to regulations as an additional load into the static Calculation and proof of stability of a large-scale unit included must become.
Da sich diese Zusatzbelastungen aus einer Verstopfung meistens an weit auskragenden Verladeauslegern befinden, ist ihr gravierender nachteiliger Einfluß auf die Dimensionierung solcher Ausleger und nachfolgenden Lager- und Stützkonstruktionen offensichtlich.Since these additional burdens from a constipation mostly arise far cantilevered loading arms are, their serious disadvantageous influence on the dimensioning of such booms and subsequent storage and support structures apparently.
Ziel der Erfindung ist es, Verstopfungen auszuschließen und damit den Masseaufwand in der Gerätekonstruktion zu senken.The aim of the invention is to exclude blockages and thus to reduce the mass expenditure in the device construction.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zu schaffen, deren Leitelemente eine zuverlässige Bündelung des Förderstromes gewährleisten und so angeordnet sind, daß sich aufbauende Verstopfungen bei Uberschreitung eines fixierten Sollwertes zur Auslösung eines Entleerungsme chanismus führen.The invention is therefore based on the object of providing a device create whose guide elements ensure a reliable bundling of the flow and are arranged in such a way that building up blockages when exceeding a fixed setpoint to trigger an emptying mechanism.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daB eine trichterförmige Leiteinrichtung aus einzelnen, am oberen Umfang schwenkbar gelagerten Segmenten besteht, die durch elastische Verbindungselemente oder durch hängende Schwerkraftmassen im unteren Bereich eng zusammengefügt sind.According to the invention, the object is achieved in that a funnel-shaped Guide device made up of individual segments pivoted on the upper circumference consists of elastic connecting elements or hanging gravity masses are closely joined together in the lower area.
Wird der Querschnitt durch das Festsetzen von Fördergut oder durch sperrige Bestandteile des Bõrdergutes stark eingeengt, so daß eine Verstopfung droht, dann werden durch die stets nach außen gerichteten Komponenten des Schüttgut druckes die Kräfte der Verbindungselemente oder Schwerkraftmassen übertroffen, so daß ein Lösen der Schurrensegmente stattfindet und der gesamte Schurreninhalt durch Öffnen oder Auseinanderklappen der Segmentteile abfließen kann.If the cross-section is caused by the setting of conveyed goods or by bulky components of the transported material are severely restricted so that there is a risk of clogging, then the outward components of the bulk material are always pressure the forces of the fasteners or gravity masses exceeded, so that a Loosening of the chute segments takes place and the entire chute contents by opening or unfolding of the segment parts can flow away.
Damit ist die an langen Auslegern gefürchtete Zusatzbelastung gar nicht zur Wirkung gekommen, und der Materi-aleinsatz für dieses Bauteil muß diesem Belastungsfall nicht mehr Rechnung tragen.This means that the additional load feared on long booms is no longer an issue did not come into effect, and the material used for this component must match this Load case no longer take into account.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles erläutert. In den zugehörigen Zeichnungen zeigen Fig. 1: die Seitenansicht einer verstopfungsfreien Leiteinrichtung mit elastischen Verbindungselementen, Fig. 2: die Draufsicht, Fig. 3: die Seitenansicht einer verstopfungsfreien Leiteinrichtung mit starren Sollbruch-Verbindungselementen, Fig. 4: die Draufsicht, Fig. 5: die Seitenansicht einer verstopfungsfreien Leiteinrichtung mit hängenden Schwerkraftmassen.The invention is explained below using an exemplary embodiment explained. In the accompanying drawings, FIG. 1 shows the side view of a blockage-free guide device with elastic connecting elements, Fig. 2: the top view, FIG. 3: the side view of a blockage-free guide device with rigid predetermined breaking connection elements, FIG. 4: the top view, FIG. 5: the Side view of a blockage-free guide device with hanging gravity masses.
Die trichterförmigen Segmente 1, die in Lagern 2 am oberen Umfang gehalten sind, werden durch elastische Verbindungselemente 3 an ihren Trennstellen verbunden und so in ihrer Normallage gehalten.The funnel-shaped segments 1, which are in bearings 2 on the upper circumference are held by elastic connecting elements 3 at their separation points connected and so in kept their normal position.
In der zweiten AusfUhrungsart bestehen die in Lagern 2 gehaltenen trichterförmigen Segmente 4 aus Fördergurten und sind durch Winkelstahl 5 an den Enden eingefaßt, welche durch starre Bruchelemente 6, z.B. Schrauben, in Normallage zusammengehalten werden.In the second version, there are those held in bearings 2 funnel-shaped segments 4 made of conveyor belts and are by angle steel 5 to the Ends bordered by rigid breaking elements 6, e.g. screws, in the normal position be held together.
In der dritten Ausung werden die trichterförmigen Segmente 1 durch an Ketten 7 hängende Schwerkraftmassen 8 zusammengehalten.In the third recess, the funnel-shaped segments 1 are through gravity masses 8 hanging on chains 7 held together.
Im Falle einer sich anbahnenden Verstopfung weiten sich die elastischen Verbindungselemente 3 oder die durchhängenden Ketten 7 soweit, bis sie die Segmente 1 freigeben bzw.In the case of a looming blockage, the elastic ones widen Connecting elements 3 or the sagging chains 7 until they reach the segments 1 release or
die Bruchelemente 6 geben sofort durch Querschnittsbruch die Segmente 4 frei und müssen bei Fortsetzung der Leitfunktion ersetzt werden.the fracture elements 6 immediately give the segments through a cross-sectional break 4 free and must be replaced if the control function is continued.
