Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand vorliegender Erfindung bildet eine Vorrichtung an Hebezeugen, welche beim Niedergang der Last eine selbstthätige Hemmung bewirkt.The subject of the present invention forms a device on hoists, which at Fall of the load causes an automatic jamming.

Ueber dem Ende der Hebezeugwelle α ist an dem Gehäuse b eine Büchse c angeordnet, innerhalb deren sich ein Metallkörper d befindet, der von vier Klauen f in centraler Lage festgehalten wird. Diese Klauen f haben ihren Drehpunkt bei χ an der Innenwandung der Büchse c und greifen mit ihren Armen über die Oberfläche und Seitenwand des Körpers d. An der der Welle α zugekehrten Fläche besitzt der Körper d einen Ansatz g, an welchen das abgerundete Ende der Welle α lose anliegt.Above the end of the hoist shaft α , a sleeve c is arranged on the housing b , within which a metal body d is located, which is held in a central position by four claws f. These claws f have their pivot point at χ on the inner wall of the sleeve c and grip with their arms over the surface and side wall of the body d. On the surface facing the shaft α , the body d has a shoulder g on which the rounded end of the shaft α rests loosely.

Die Verbindung zwischen dem Körper d und der Welle α wird durch ein auf das Ende der Welle aufgekeiltes Sperrrad h bewirkt, in dessen Zähne unter Federdruck stehende, in Bohrungen des Körpers d angeordnete Bolzen i eingreifen. Beim Aufgang der Last gleiten die Bolzen i lose über die Zähne des Sperrrades h hinweg, so dafs der Körper d in Ruhe bleibt.The connection between the body d and the shaft α is brought about by a ratchet wheel h wedged onto the end of the shaft, in the teeth of which spring-loaded bolts i located in bores of the body d engage. When the load is lifted, the bolts i slide loosely over the teeth of the ratchet wheel h , so that the body d remains at rest.

Beim Niedergang der Last dagegen wird der Körper d von der Welle α mitgenommen, und bei dem gleichzeitig in der Welle auftretenden achsialen Druck wird der Körper d durch die Welle α seitlich verschoben, was zur Folge hat, dafs die Klauen f um ihren Drehpunkt χ gedreht werden und sich mit ihren seitlichen Armen fest gegen den Körper d anlegen. Hierdurch werden Reibungswiderstände erzeugt, die den Rücktrieb des Hebezeuges weit übertreffen und somit eine selbstthäge Hemmung des Hebezeuges bewirken.At the fall of the load, however, the body is d from the shaft α entrained and in which simultaneously occurring in the shaft axial pressure of the body is d α by the shaft displaced laterally, which has the consequence, that the claws f about its pivot point χ rotated be and mess with their lateral arms firmly against the body d. As a result, frictional resistances are generated which far exceed the return drive of the hoist and thus cause the hoist to self-inhibit.
