Description

Spannvorrichtung für Förderbänder Die Erfindung bezieht sich auf eine Spannvorrichtung für Förderhänder, deren Umlenk- bzw. Spanntrommel mit ihrer Achse in Längsschlitzen des Bandtraggerüstes bzw. der Seitenschilde längsverschiebbar gelagert ist. Um den mit Spanngewichten, Spannzylindern od. dgl. verbundenen komplizierten Aufbau sowie die Montage und das Spannen selbst zu vereinfachen und gleichzeitig ein Regulieren des Bandlaufes zu ermöglichen, wird eine Ausbildungsform vorgeschlagen, die bei den in Betrieb befindlichen Förderern ohne größere Schwierigkeiten nachträglich vorgesehen werden kann.Tensioning device for conveyor belts The invention relates to a Clamping device for conveyor handlers, their deflection or clamping drum with their axis Can be moved lengthways in the longitudinal slots of the belt support structure or the side shields is stored. To deal with the complicated with tension weights, tension cylinders or the like To simplify construction as well as assembly and clamping itself and at the same time To enable regulation of the belt run, a form of training is proposed, those with the conveyors in operation without any major difficulties afterwards can be provided.

Die Erfindung besteht demgemäß im Grundgedanken darin, daß die Trommelachse mit drehbar gelagerten Spi ralsegmenten zusammenwirkt. The invention is accordingly in the basic idea that the drum axis cooperates with rotatably mounted spiral segments.

Durch diese einfache Vorrichtung kann das erforderliche Nachspannen mit einem Handgriff am Segmenthebel schnellstens durchgeführt werden. Die Bohrungen in den Spiralsegmenten und im Bandtraggerüst ermöglichen nicht nur ein Festhalten mit Feineinstellung in verschiedenen Spannstellungen, sondern auch noch eine auf beiden Seiten unterschiediche Feststellung der Spiralsegmente. so daß eine Schräg stellung der Trommelachse zur Korrektur des Bandlaufes möglich ist. With this simple device, the required re-tensioning can be carried out as quickly as possible with a handle on the segment lever. The holes in the spiral segments and in the belt support structure not only allow holding on with fine adjustment in different clamping positions, but also one on Different determination of the spiral segments on both sides. so that a slant position of the drum axis to correct the belt run is possible.

Die Führung der Achsscheiben in einer Nut der Spiralsegmente gewährleistet eine einwandfreie Führung der Trommel und verhindert ein Abrutschen der Segmente von den Scheiben. Dahei ist es zwedmäßig. daß die Scheiben auf der Trommelachse lösbar liefestigt sind. Dadurch wird eine Möglichkeit geschaffen, die Scheiben jederzeit gegen andere von kleinerem oder größerem Durchmesser auszutauschen. um für verschiedene Bandlängen jeweils den vollen Spannxveg mittels der Spiralsegmente ausnutzen zu können. The guidance of the axle washers in a groove in the spiral segments is guaranteed proper guidance of the drum and prevents the segments from slipping from the discs. Dahei it is zwedormal. that the discs on the drum axis are releasably fixed. This creates a way to remove the slices at any time to be exchanged for others of smaller or larger diameter. around for different Use the full length of the strap by means of the spiral segments can.

Spannvorridi.tuigen für Förderbandanlagen zählen an sich grundsätzlich zum Stand der Technik. So wurde bisher eine Nachspannung dieser Bänder durch Gegenrichten mittels Spindeln od. dgl. erzielt, die aber alle einen äußerst komplizierten Aufbau aufweisen und dadurch bedingt erheblichen Betriebsstörungen unterworfen waren. Exzenterverstellüngen waren bisher nur bei Kettenspannern bekanntgeworden, jedoch wurde dieses Prinzip nicht auf Nachspannvorrichtungen für Förderhänder, übertragen. Spannvorridi.tuigen for conveyor belt systems count in principle to the state of the art. So far, a post-tensioning of these ligaments by counter-straightening has been implemented By means of spindles or the like. Achieved, but all of them have an extremely complicated structure and were consequently subject to significant operational disruptions. Eccentric adjustments were previously only known from chain tensioners, but this principle was adopted not transferred to tensioning devices for conveyor handlers.

In der Zeichnung ist ein .Ausführullgsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 die Seitenansicht der Spaunvorrichtung, Fig. 2 die Draufsicht zu Fig. 1. In the drawing, an .Ausführullgsbeispiel the invention is shown. 1 shows the side view of the spauning device, and FIG. 2 shows the top view Fig. 1.

Das mit Handgriffen 2 versehene Traggerüst 1 eines kurzen Bandförderers weist an den Seitenschilden durch Anschläge 4 begrenzte Schlitze 3 auf, in denen die Spanntrommel 5 mittels ihrer Achse 6 ver- schiebbar gelagert ist. Außerhalb der Tragkonstruktion 1 des Förderbandes 7 ist auf der Trommelachse 6 je eine Scheibe 8 bzw. 8a befestigt. Diese Scheiben wirken mit auf den Zapfen 9 bzw. 9a drehbar gelagerten Spiralsegmenten 10 bzw. 10 a zusammen. The supporting frame 1 of a short belt conveyor provided with handles 2 has on the side shields delimited by stops 4 slots 3 in which the clamping drum 5 by means of its axis 6 is slidably mounted. Except for The support structure 1 of the conveyor belt 7 is on each drum axis 6 a disk 8 or 8a attached. These disks have a rotatable effect on the pin 9 or 9a mounted spiral segments 10 and 10 a together.

Diese Spiralsegmente 10 bzw. 10a weisen beispielsweise drei Bohrungen 12 auf, die mit den in den Seitenschilden vorgesehenen Bohrungen 13 in Überdeckung gebracht werden können. Läßt beispielsweise die Bandspannung während des Betriebes nach, so werden auf beiden Seiten die Bolzen gelöst, und die Trommelachse wird durch Schwenken der Hebel 11 und 11a und damit der SpiralsegmenteiO und 10a um den für die Nachspannung erforderlichen Betrag nach außen geschoben. Nach dem Spannen werden die Spiralsegmente 10 und 10a wieder mittels Bolzen an den Seitenschilden befestigt. Die Bohrungen 12 lassen sich in unsymmetrischer Reihenfolge auf beiden Seiten mit den Bohrungen 13 in Überdeckung bringen, wodurch die Laufrichtung des Förderbandes korrigiert werden kann. Selbstverständlich können bei schwereren Förderbandanlagen die Hebel 11 und 11 a mit von einem Druckmittel betätigten Zylindern oder anderen Hilfseinrichtungen zusammenarbeiten.These spiral segments 10 and 10a have, for example, three bores 12, which overlap with the holes 13 provided in the side shields can be brought. For example, leaves the belt tension during operation after, the bolts are loosened on both sides and the drum axle is through Pivoting the lever 11 and 11a and thus the SpiralsegmenteiO and 10a around the for the amount of tension required is pushed outwards. After clamping will be the spiral segments 10 and 10a are again fastened to the side shields by means of bolts. The holes 12 can be in an asymmetrical sequence on both sides bring the bores 13 into overlap, whereby the running direction of the conveyor belt can be corrected. Of course, with heavier conveyor belt systems the levers 11 and 11 a with cylinders actuated by a pressure medium or others Auxiliary facilities work together.
