Description

Ausrückvorrichtung des' Antriebs eines Gurtbecherwerks. In Abänderung der durch das Hauptpatent geschützten Ausrückvorrichtung des Antriebs eines Gurtbecherwerks wirken erfindungsgemäß die im Kranz der Kopfgurtscheibe angeordneten Metallbüchsen statt auf Kontaktthermometer auf Schmelzkontakte ein. Bei der- Erhitzung der Metallbüchsen infolge Schleifens des Gurtes werden die Schmelzkontakte gelöst und schließen die Pole des Hilfsstromkreises. Die weiteren Vorgänge, insbesondere die Endwirkungen, die sich aus der Schließung des Hilfsstromkreises ergeben, sind aus dem Hauptpatent bekannt.Disengaging device of the drive of a belt bucket elevator. In modification the release device of the drive of a belt bucket elevator, which is protected by the main patent according to the invention, the metal bushings arranged in the rim of the head belt pulley act instead of contact thermometers on fusible contacts. During the heating of the metal cans as a result of the belt being dragged, the melting contacts are released and close Poles of the auxiliary circuit. The further processes, in particular the end effects, which result from the closure of the auxiliary circuit are from the main patent known.

Die Zeichnung zeigt eine beispielsweise Ausführungsform der Abänderung in einem schematischen Aufriß.The drawing shows an example embodiment of the modification in a schematic elevation.

Die Büchse b1 ist in den Kranz der Kopfgurtscheibe a des Becherwerks eingesetzt. Im Innern der Büchse b1 sind zwei Kupferscheiben o. dgl. n und n1 untergebracht, die ein Steg o aus leicht schmelzbarem Metall miteinander verbindet. Die beiden, nur durch den leicht schmelzbaren Steg o verbundenen Kupferscheiben halten eine gespannte Druckfeder P fest, die das Bestreben hat, die Scheibe n nach unten zu drücken. In die Büchse b1 ist eine mit zwei Kontaktstiften y und s versehene Isolierhülse q eingeschraubt. An die Stifte r und s sind die Leitungsdrähte des Hilfsstromkreises angeschlossen.The sleeve b1 is in the rim of the head belt pulley a of the bucket elevator used. Inside the sleeve b1 two copper washers or the like n and n1 are housed, which connects a web o made of easily fusible metal. The two, only through the easily fusible web o connected copper washers hold a tensioned compression spring P firmly, which has the tendency to move the disc n downwards to press. In the sleeve b1 is provided with two contact pins y and s insulating sleeve q screwed in. The auxiliary circuit lead wires are attached to pins r and s connected.

Tritt eine übermäßige Erhitzung der Büchse bi durch Reibung des Gurtes c auf der Scheibe a ein, so schmilzt der Verbindungssteg o, und die gespannte Feder p drückt die Scheibe n gegen die beiden Kontaktstifte y und s, wodurch der Hilfsstromkreis geschlossen wird.. Dies hat zur Folge, daß im Zusammenhang mit einem Hilfsschalter, etwa durch das Mittel eines Relais, der Arbeitsstrom zum Ausrücken des Antriebs für das Becherwerk, eingeschaltet wird.If there is excessive heating of the sleeve bi due to friction of the belt c on the disk a, the connecting web o melts and the tensioned spring p pushes the disk n against the two contact pins y and s, causing the auxiliary circuit is closed .. This has the consequence that in connection with an auxiliary switch, for example by means of a relay, the operating current to disengage the drive for the bucket elevator is switched on.

PATENT-ANSPRÜcHE: z. Ausrückvorrichtung des Antriebs eines Gurtbecherwerks nach Patent 311711, dadurch gekennzeichnet; daß die im Kranz der Kopfgurtscheibe angeordneten Metallbüchsen (b1) Schmelzkontakte trägen, in denen bei übermäßiger Erhitzung ein Verbindungsglied (o) schmilzt, wodurch ein Hilfsstromkreis geschlossen und der Antrieb des Becherwerks ausgeschaltet wird. PATENT CLAIMS: e.g. Disengagement device for the drive of a belt bucket elevator according to patent 311711, characterized; that the one in the wreath of the head belt pulley arranged metal sleeves (b1) melt contacts sluggish, in which with excessive Heating a link (o) melts, thereby closing an auxiliary circuit and the drive of the bucket elevator is switched off. 2. Ausrückvorrichtung nach Anspruch z, dadurch gekennzeichnet, daß das leicht schmelzbare Glied (Steg o) mittels einer Scheibe (n) o. dgl. eine gespannte Feder (p) festhält, die nach dem 'Schmelzen des Steges (o) frei wird und die Scheibe (n) auf die Kontaktstifte (y und s) des Hilfsstromkreises drückt, wodurch dieser geschlossen wird.2. Release device according to claim z, characterized in that the easily fusible member (web o) by means of a Washer (s) or the like holds a tensioned spring (p) which, after the 'melting of the Bridge (o) is free and the disc (n) on the contact pins (y and s) of the auxiliary circuit presses, which closes it.
