Abstract

The drive installation is for an adjustment unit used for opening and closing of a flat slider for solids. It is used where the control of the slider blade is carried out by a chain wheel and a strap chain. A fixed length strap chain linked to a push rod end is guided over a reversing roller from the neutral axis of the pull rod onto a chain wheel and from where over a second reversing roller back in to the neutral axis and to the other end of the push rod end. The distance of the running surfaces of the reversing rollers from each other is either the same or smaller than the roller dia. of the chain wheel.

Description

Vorrichtung zum Antrieb eines Stellorganes, Device for driving an actuator,

vorzugsweise eines Flachschiebers Die Erfindung betrifft eine Antriebsvorrichtung eines Stellorganes, vorzugsweise zum Öffnen und Schließen eines mit einem Schieberblatt ausgebildeten Flachschiebers für Feststoffe, das beispielsweise an dem Auslauf einer Silozelle für Getreide angeordnet ist. preferably a flat slide The invention relates to a drive device an actuator, preferably for opening and closing one with a slide blade trained flat slide for solids, for example at the outlet of a Silo cell for grain is arranged.

Bei derartigen Flachschiebern muß beim Schließvorgang das Schieberblatt durch den Gutstrom gesteuert werden, wobei außer den Reibungswiderständen der Druck der Schüttgutsäule auf das Schieberblatt zu überwinden ist0 Je größer die zu schließende Auslaßöffnung istt um so größere Kräfte müssen überwunden werden. Dabei besteht die Gefahr, daß das Schieberblatt in seiner FLilirung kantet, so daß sich die aufzubringende Gesamtkraft erhöht.In the case of such flat slides, the slider blade must during the closing process can be controlled by the flow of material, with the addition of frictional resistance and pressure the bulk material column to be overcome on the slide valve is0 the larger the to be closed The greater the forces that have to be overcome at the outlet opening. There is the risk that the slide leaf cant in its FLilirung, so that the to be applied Overall strength increased.

Es ist ein Flachschieber bekannt, bei dem unter dem Schieberblatt eine Zahnstange oder anstelle derselben eine endliche Laschenkette befestigt ist, in die ein stationär gelagertes Ritzel eingreift, das in Umdrehung versetzt wird.A flat slide valve is known in which under the slide valve blade a toothed rack or instead of a finite link chain is attached, in which a stationary mounted pinion engages, which is set in rotation.

Bei einem anderen bekannten Flachschieber sind unter dem Schieberblatt zwei parallel angeordnete Laschenketten befestigt, in die je ein Kettenrad eingreift. Die beiden Kettenräder werden über einen gemeinsamen Antrieb gesteuert.In another known flat slide are under the slide blade two parallel link chains attached, each engaging a sprocket. The two chain wheels are controlled by a common drive.

Diese bekannten Flachschieber sind zum Verschließen kleiner Querschnittsöffnuggen geeignet, da relativ kleine Kräfte erforderlich sind. Muß jedoch der Gutstrom aus einer Silogroßzelle abgeriegelt werden, dessen Auslauf eine relativ große Querschnittsfläche hat, treten enorme Kräfte auf, die von den Antriebselementen übertragen werden müssen. Insbesondere die Kettenräder sind einem großen Verschleiß ausgesetzt, da immer nur wenige Zähne im Eingriff stehen.These known flat slide valves are used to close small cross-sectional openings suitable because relatively small forces are required are. But I have to the flow of goods from a large silo cell are blocked, the outlet of which is a relative has a large cross-sectional area, enormous forces arise from the drive elements must be transferred. The sprockets in particular are subject to great wear and tear exposed because there are always only a few teeth in contact.

Außerdem ist bei diesen bekannten Flachschiebern die wirkende Zugkraft nicht in die neutrale Achse des Schieberblattes verlegt, so daß zusätzlich noch Drehmomente wirken.In addition, in these known flat slides, the tensile force acting not moved in the neutral axis of the slide leaf, so that in addition Acting torques.

Bei einem anderen bekannten Flachschieber sind die Zugkräfte der beiderseits des Schieberblattes befestigten endlosen Kettenstränge in die neutrale Achse des Schieberblattes verlegt. Er hat jedoch den Nachteil, daß bei der Übertragung der Zugkräfte eine ungleiche Längung der Kettenstränge erfolgt, die zu zusätzlichen Reibungswiderständen in der Schieberführung führt.In another known flat slide, the tensile forces are on both sides of the slide blade attached endless chain strands in the neutral axis of the Slider sheet relocated. However, it has the disadvantage that when transferring the Tensile forces an unequal elongation of the chain strands takes place, which leads to additional Frictional resistance in the slide guide leads.

Der Erfindung liegt die Aufgabe zugrunde, die Ubertragung der Kräfte auf das Schieberblatt zu verbessern. Außerdem soll der Verschleiß der Antriebselemente auf ein Minimum reduziert werden. Die Funktionssicherheit soll gesteigert werden.The invention is based on the task of transmitting the forces to improve on the slide blade. In addition, the wear of the drive elements can be reduced to a minimum. The functional reliability is to be increased.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß in der neutralen Achse einer an dem Schieberblatt angelenkten und in einem an dem Schieberrahmen angeordneten Gehäuse gelagerten Schubstange eine endliche Laschenkette an einem Schubstangen ende angelenkt ist. Die Laschenkette ist über eine Umlenkrolle aus der neutralen Achse der Schubstange auf ein Kettenrad und von dort über eine zweite Umlenkrolle wieder in die neutrale Achse zum anderen Schubstangenende geführt. Eins der beiden Schubstangenenden ist mit einer Kettenspannvorrichtung ausgebildet. Die Laufflächen der beiden Umlenkrollen liegen in einer Entfernung voneinander, die gleich oder kleiner als der Wälzkreisdurchmesser des Kettenrades ist.According to the invention the object is achieved in that in the neutral Axis one hinged to the slide blade and one on the slide frame arranged housing mounted push rod a finite link chain on one Push rod end is hinged. The link chain is made via a pulley the neutral axis of the push rod to a sprocket and from there via a second Deflection roller guided back into the neutral axis to the other end of the push rod. one the two push rod ends is designed with a chain tensioning device. the Treads of the two pulleys are at a distance from each other, the is equal to or smaller than the pitch circle diameter of the sprocket.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß sich das Schieberblatt des Flachscbiebers trotz maxjmaler Belastung funktionssicher steuern läßt. Der Verschleiß der Antriebselemente, insbesondere des Kettenrades, ist auf ein Minimum reduziert. Die Längung der Laschenkette übt keinen negativen Einfluß auf die Führung des Schieberblattes aus.The advantages achieved with the invention are in particular: that the slider blade of the flat screen works reliably in spite of the maximum load controls. The wear the drive elements, in particular of the sprocket is reduced to a minimum. Exercise the elongation of the plate link chain no negative influence on the guidance of the slide blade.

Die Erfindung soll an einem Ausführungsbeispiel nachstehend näher erläutert werden. In der zugehörigen Zeichnung zeigen: Fig. 1: eine schematische Darstellung des Stellantriebes im Längsschnitt, Fig. 2: die Schubstange im Schnitt A-A nach Fig. 1 An einem Schieberblatt 1 das in einem in Fig. 1 nur zum Teil angedeuteten Schieberrahmen 2 gleitet, ist eine Schubstange 3 angelenkt und in einem Gehäuse 4 geführt. Das Gehäuse 4 ist an dem Schieberrahmen 2 befestigt. Die Schubstange 3 ist als C-Profil ausgebildet. An den Schubstangenenden 5; 6 ist in der neutralen Achse 7 der Schubstange 3 eine Laschenkette 8 angelenkt. Außerdem ist das Schubstangenende 6 mit einem Kettenspanner 12 ausgebildet. In dem Gehäuse 4 sind zwei Umlenkrollen 9; 9' derart angeordnet, daß die Mitte 16 der auf einer Lauffläche 10 au fliegenden Laschenkette 8 sich mit der neutralen Achse 7 der Schubstange 3 deckt. Die beiden Umlenkrollen 9; 9' sind im Abstand a voneinander gelagert. Im Abstand b von den Druckrollen 9; 9' ist ein Kettenrad 11 in dem Gehäuse 4 angeordnet. Dabei ist der Abstand b größer als die Entfernung c der beiden Laufflächen 10 voneinander, so daß der Umschlingungswinkel d der Laschenkette 8 auf dem Wälzkreisdurchmesser 17 des Kettenrades 11 größer als 180 Grad ist. Das Kettenrad 11 wird durch einen nicht dargestellten Motor in die Drehrichtung 13; 14 bewegt.The invention is to be described in more detail below using an exemplary embodiment explained. The accompanying drawings show: FIG. 1: a schematic Representation of the actuator in longitudinal section, Fig. 2: the push rod in section A-A according to FIG. 1 On a slide leaf 1 that is only partially indicated in FIG. 1 Slider frame 2 slides, a push rod 3 is articulated and in a housing 4 led. The housing 4 is fastened to the slide frame 2. The push rod 3 is designed as a C-profile. At the push rod ends 5; 6 is in the neutral Axis 7 of the push rod 3 is a link chain 8 articulated. Also is the push rod end 6 formed with a chain tensioner 12. In the housing 4 there are two pulleys 9; 9 'arranged so that the center 16 of the flying on a tread 10 au Link chain 8 coincides with the neutral axis 7 of the push rod 3. The two Pulleys 9; 9 'are mounted at a distance a from one another. At a distance b from the Pressure rollers 9; 9 ′, a chain wheel 11 is arranged in the housing 4. Here is the Distance b greater than the distance c between the two running surfaces 10 from one another, see above that the wrap angle d of the link chain 8 on the pitch circle diameter 17 of the sprocket 11 is greater than 180 degrees. The sprocket 11 is not by one shown motor in the direction of rotation 13; 14 moves.

Das Schieberblatt 1 befindet sich in Schließstellung. Soll der Schieber geöffnet werden, wird das Kettenrad 11 in die Drehrichtung 13 versetzt. Das Kettenrad 11 bewegt die Laschenkette 8 über die Umlenkrolle 9 in Richtung der Zugkraft Zk Das Schieberblatt 1 sowie die Schubstange 3 gleiten nach rechts. Der Schieber öffnet sich. Beim Öffnungsvorgang des Schiebers hat die Schubstange 3 keine Kräfte zu übertragen.The slide leaf 1 is in the closed position. Should the slide are opened, the sprocket 11 is set in the direction of rotation 13. The sprocket 11 moves the link chain 8 over the pulley 9 in the direction of the tensile force Zk The slide blade 1 and the push rod 3 slide to the right. The slide opens themselves. Has during the opening process of the slide the push rod 3 none To transfer forces.

Soll der Schieber geschlossen werden, so wird das Kettenrad 11 in die Drehrichtung 14 bewegt. Dadurch entsteht im rechten Kettenstrang 15 die Zugkraft i1 in deren Richtung die Laschenkette 8 gleitet. Da die Laschenkette 8 auch am rechten Schubstangenende 6 angelenkt ist, bewegt sie die Schubstange 3 nach links und bringt den Schieber in die Schließstellung.If the slide is to be closed, the sprocket 11 is in the direction of rotation 14 moves. This creates the tensile force in the right chain strand 15 i1 in the direction of which the link chain 8 slides. Since the link chain 8 also on the right Push rod end 6 is hinged, it moves the push rod 3 to the left and brings the slide in the closed position.
