KLASSE 35: Hebezeuge.CLASS 35: Hoists.
Die Vorrichtung bezweckt eine erhöhte Sicherheit im Betriebe von Hebezeugen und ist in Fig. 1 und 2 beiliegender Zeichnung dargestellt.The purpose of the device is to increase safety in the operation of hoists and is shown in Figs. 1 and 2 of the accompanying drawings.
Das Bremsgehäuse α mit angegossenem Triebrade t ist auf der Antriebwelle b fest aufgekeilt. Die Welle b ist in der Büchse c gelagert, welche sich im Windenschilde d dreht.The brake housing α with the cast-on drive wheel t is firmly keyed onto the drive shaft b. The shaft b is mounted in the sleeve c , which rotates in the winch shield d.
Das im Innern des Bremsgehäuses α befindliche Ende der Büchse c hat zwei sich gegenüberliegende Lappen, an welchen mittelst der Bolzen e die Druckschieneny angreifen, welche an dem anderen Ende durch die Bolzen g mit den Bremsklötzen h verbunden sind.The inside of the brake housing α located end of the sleeve c has two opposing tabs, on which by means of the bolt e, the pressure rails attack which are connected at the other end by the bolts g to the brake pads h .
An dem aufserhalb des Windenschildes d liegenden Ende der Büchse c ist die Kurbel i mit Gewinde aufgeschraubt und mit zwei Kopfschrauben, befestigt.The crank i is screwed on with a thread and fastened with two head screws on the end of the sleeve c lying outside the winch shield d.
Die Bremsklötze h, welche an den Bremsflächen mit Leder Bekleidet sind, werden zwischen den Putzen / geführt, welche an der als Gehäusedeckel dienenden Scheibe k angegossen sind.The brake pads h, which are clad with leather on the braking surfaces, are guided between the plasters / which are cast onto the disc k serving as the housing cover.
Die Scheibe k, an welcher an der Aufsenseite das Sperrrad m angegossen ist, dreht sich auf der Nabe des Windenschildes d, jedoch nur in der Drehrichtung der Kurbel i, da der am Windenschild d drehbar angebrachte Sperrkegel η nur diese Drehrichtung zuläfst.The disk k, on which the ratchet wheel m is cast on the outside, rotates on the hub of the winch shield d, but only in the direction of rotation of the crank i, since the locking cone η rotatably attached to the winch shield d only allows this direction of rotation.
Die Bremsklötze h werden durch die Federn 0, welche auf der Scheibe k befestigt sind, stets gegen das Bremsgehäuse geprefst.The brake pads h are always pressed against the brake housing by the springs 0, which are fastened on the disk k.
Wird nun die Kurbel i in der Pfeilrichtung gedreht, so wird das Bremsgehäuse α mit der Antriebwelle b mittelst der sich durch die Kniefest gegenpressenden Brems hebelwirkungIf the crank i is now rotated in the direction of the arrow, the brake housing is α with the drive shaft b by means of the brake lever effect, which is pressed against the knee
klotze h mitgenommen und damit die Last gehoben.Klotze h taken along and lifted the load.
Wird die Kurbel i plötzlich losgelassen, so schlägt dieselbe nur so:.weit zurück, bis der Sperrkegel η den nächsten Zahn des "Sperrrades m gefafst hat und die Last steht.If the crank i is suddenly released, it only strikes as follows:. Far back until the locking cone η has gripped the next tooth of the "ratchet wheel m and the load is stationary.
Soll die Last gesenkt werden, so. wird die Kurbel i ein wenig zurückgedrückt, wodurch dann die Bremsklötze h von dem Bremsge-.. häuse α abgehoben werden, worauf die Last mit beliebiger Geschwindigkeit, je nach dem mehr oder minder erfolgten Zurückdrücken der Kurbel gesenkt werden kann.If the load is to be lowered, so. the crank i is pushed back a little, whereby then the brake pads h are lifted from the brake .. housing α , whereupon the load can be lowered at any speed, depending on the more or less pushed back of the crank.
