Sicherungseinrichtung für eine an Seilen aufgehängte und daran mit zwei Handwinden auf- und abbewegbare ArbeitsbühneSafety device for a work platform that is suspended from ropes and can be moved up and down with two hand winches
Die Neuerung betrifft eine Sicherungseinrichtung für eine an Seilen aufgehängte und daran mit zwei Handwinden auf- und abbewegbare Arbeitsbühne.The innovation concerns a security device for a Suspended ropes that can be moved up and down with two hand winches Working platform.
Der Neuerung liegt die Aufgabe zugrunde, die Sicherheit derartiger Arbeitsbühnen zu erhöhen.The innovation is based on the task of the security of such Raise work platforms.
Dieses Ziel wird erreicht, durch je eine an den Stirnseiten der Arbeitsbühne angeordnete, auf je ein Fangseil wirkende und mittels eines Kniehebels lüftbare Sicherheitsschnellblockierung. This goal is achieved by a safety rope that is arranged on the front sides of the work platform and acts on each one and a quick release safety lock that can be released by means of a toggle lever.
Bei Auf- und Abwärtsfahrt wird die Sicherheitsschnellblockierung mit dem Kniehebel ausgeschaltet. In der Arbeitsstellung wird die Bühne von den beiden Fangseilen und zwei Windseilen festgehalten und durch das Vorhandensein von damit insgesamt 4 Aufhängepunkten gegen Schaukel- und Pendelbewegungen stabilisiert. When moving up and down, the quick safety lock is switched off with the knee lever. In the working position the stage is held in place by the two safety ropes and two wind ropes and by the presence of them as a whole 4 suspension points stabilized against rocking and pendulum movements.

Die Sicherheitssehnellblockierungsvorrichtung ist an sich bekannt. Sie arbeitet nach dem Frosehklemmprinzip, d.h. je größer der Zug am Fangseil, desto größer wird der Anpreßdruck der Klemmen und damit das Haltevermögen am Fangseil. Die Vorrichtung öffnet sich automatisch beim Durchgang des Seiles in Zugrichtung und schließt sich zwangsläufig bei entgegengesetzter Seilbewegung. Bei gewollten Absenken der last wird das Fangseil durch ständigen leichten Druck auf den Kniehebel geöffnet gehalten, um sich sofort zu schließen, sobald der Druck aufhört. Beim Hochziehen der Last bzw. Anziehen des Sicherheitsseiles öffnen sich die Klemmstücke selbsttätig, so daß die Sicherheitseinrichtung ohne weiteres Zutun auf dem Seil mitläuft. Sobald die Seilbewegung aufhört oder umgekehrt wirkt, schließen sich die Klemmstücke zwangsläufig und halten das Seil fest. Je stärker der G-egenzug, umso fester greifen die Klemmstücke infolge der vorerwähnten Froschklemmenwirkung. Beim Absenken der last oder Nachlassen des Seiles wird die Vorrichtung durch einen leichten Druck auf den Kniehebel entspannt und während der Dauer der Abwärtsfahrt entspannt gehalten. Die Kraftwirkung für die Sicherheitsschnellblockierung wird durch eine Druckfeder hervorgerufen.The safety tendon blocking device is known per se. It works according to the frost clamp principle, i.e. the greater the pull on the safety rope, the greater the contact pressure of the clamps and thus the holding capacity on the safety rope. The device opens automatically when the rope passes in the direction of pull and inevitably closes when the rope moves in the opposite direction. If the load is deliberately lowered, the safety rope will break constant light pressure on the knee lever kept open to close immediately as soon as the pressure ceases. When the load is pulled up or the safety rope is tightened, the clamping pieces open automatically, so that the safety device runs along on the rope without any further action. As soon as the rope movement stops or the other way around, they close the clamping pieces inevitably and hold the rope tight. The stronger the pull, the more firmly the clamping pieces grip as a result of the aforementioned Frog clamp effect. When the load is lowered or the rope is slackened, the device is activated by a slight pressure relaxed on the knee lever and kept relaxed for the duration of the descent. The force effect for the safety quick-locking is caused by a compression spring.
Die Neuerung ist in der Zeichnung in zwei Figuren dargestellt und wird im folgenden näher erläutert. An einer Eekstrebe 1 einer Arbeitsbühne ist eine Sicherheitsschnellblockierung 2, durch die ein Fangseil 3 hindurchläuft, mittels einer Schelle 4 befestigt» An einen Betätigungshebel 5The innovation is shown in the drawing in two figures and is explained in more detail below. There is a quick safety lock on an eek brace 1 of a work platform 2, through which a safety rope 3 runs, attached by means of a clamp 4 »To an actuating lever 5
