Description
Kratzband Zur Förderung von im Bergbau gewonnenem Material, beispielsweise Kohle, sind Rutschen in Anwendung, in denen ein Förderelement umläuft. Man kann zwischen Rutschen mit geraden und solchen mit gewölbten Proflen unterscheiden. Bei ersteren bestreichen die Kratzer die ganze Breite des Profils und haben innerhalb des Profils Seitenführung. Aus dieser Ursache müssen derartige Förderer mehr oder weniger gut ausgerichtet verlegt werden, damit die Kratzer sich nicht festbeißen infolge allzu: großer Seitenreibung.Scraper belt For conveying material obtained in mining, for example Coal, slides are used in which a conveyor element rotates. One can differentiate between slides with straight and those with curved profiles. at the former, the scratches cover the entire width of the profile and have inside of the side guide profile. For this reason, such sponsors must be more or be laid less well aligned so that the scratches do not stick as a result of too: great lateral friction.
Kratzförderer mit gewölbtem Profil haben vor denen finit flachem Profil den Vorzug, daß die Kratzer nicht die ganze kutschenbreite bestreichen müssen, weil infolge der Profilwölbung das Gut stets dein tiefsten Profilpunkt zustrebt, d. h. dem Punkt, an dein in der Regel der Förderer arbeitet. So ist ein Förderer bekanntgeworden, dessen Kratzband runde Scheiben trägt, welches in einem Schlitzrohr von größerem Durchmesser, als dem der Kratzbandscheiben entspricht, läuft. Letzteres ist aber für Gut unterschiedlicher Stückgröße, wie z. B. Kohle, ungeeignet, weil die großen Stücke nicht mitgenommen werden. Hierfür eignet sich erfindungsgemäß nur ein breiter und flacher Förderer. Wenn man in einem derartig breiten, schwach gewölbten Profil ein Kratzband mit den bekannten runden Scheiben laufen läßt, so ist der Raum, den dieser Förderer bestreicht, zu klein im Verhältnis zum Querschnitt des Profils. Die Folge davon ist, daß nicht der ganze Kohlenquerschnitt durch den Förderer in Bewegung gesetzt wird, sondern nur ein kleiner Teil in der Nähe der Förderscheiben.Scraper conveyors with a curved profile have a finitely flat profile in front of them the advantage that the scratches do not have to cover the entire width of the carriage, because Due to the curvature of the profile, the good always strives towards its lowest profile point, d. H. the point at which the sponsor usually works. This is how a sponsor became known whose scratch tape carries round discs, which in a slotted tube of larger Diameter, than that of the scratch disk, runs. But the latter is for goods of different sizes, such as B. Coal, unsuitable because the big ones Pieces are not taken. According to the invention, only a wide one is suitable for this and flat conveyor. If you are in such a wide, slightly curved profile runs a scratching belt with the well-known round discs, that's the space that this conveyor sweeps too small in relation to the cross-section of the profile. The consequence of this is that not the entire coal cross-section through the conveyor in Movement is set, but only a small part near the conveyor discs.
Hier tritt erfindungsgemäß - dadurch ein Wandel ein, indem statt der runden Mitnehmerbleche ein Mitnehmerprofil breiterer Ausladung zur Anwendung gelangt. Derartige breite 11litnehmer erfordern wiederum eine Führung: Diese würde aber bei Ausbildung nach Art der üblichen Kratzbänder mit ebenem Boden zu dem obengenannten Übelstand führen.According to the invention, a change occurs here by instead of round driver plates, a driver profile with a wider projection is used. Such wide drivers again require a guide: This would, however, be Training in the manner of the usual scratching belts with a flat bottom to the above Cause evil.
Erfindungsgemäß wird daher in dem Muldenprofil a ein Mitnehmer b geführt, dessen Krümmung dein der-Mulde gleich ist und der genügend :Seitenspiel besitzt, daß er bei ungenauer Verlegung des Förderers seitlich ausweichen kann, ohne daß er die gute Bodenauflage verliert. .According to the invention, therefore, a driver b is guided in the trough profile a, the curvature of which is equal to the trough and which has enough: lateral play that he can move sideways if the conveyor is inaccurately laid without losing the good floor contact. .
Bei flachem Einfallen können in die Mulde a zur Verringerung des Reibungskoeffizienten in an sich bekannter Weise Glättmittel eingelegt werden, beispielsweise emaillierte Bleche c.In the case of a shallow dip, the recess a can reduce the coefficient of friction smoothing agents are inserted in a manner known per se, for example enamelled Sheets c.
