PATENTAMT.PATENT OFFICE.

Es ist bei Kranen und Hebezeugen aller Art bekannt, einen Magneten zusammen mit einer Zange, einem Bügel oder mit einem Selbstgreifer arbeiten zu lassen. Hierbei tritt jedoch der Übelstand auf, daß die Tragfähigkeit des Magneten die gleiche wie diejenige des Greif Werkzeuges sein muß. Dieser Nachteil soll durch die gegenwärtige Erfindung beseitigt werden.It is known in cranes and hoists of all kinds to have a magnet together a pair of pliers, a bracket or a self-gripper. Here however, there is an inconvenience that the load capacity of the magnet is the same as that of the gripping tool must be. This disadvantage is addressed by the present invention be eliminated.

ίο Das Neue besteht dabei darin, daß ein kleiner Magnet von geringer Tragfähigkeit mehrere Male kleinere Massen Eisen aufhebt und in einen Bügel oder Behälter schwingt, welcher während dieser Zeit in Ruhe verharren kann. Der Magnet übergibt dem Behälter das Eisen, hebt neues an usf., bis der Behälter seiner Tragfähigkeit entsprechend belastet ist.ίο The new thing is that a small magnet with a low load-bearing capacity picking up small masses of iron several times and swinging it into a bracket or container, who can remain calm during this time. The magnet passes the container the iron, lifts new ones, etc., until the container corresponds to its load-bearing capacity is burdened.

Auf den beiliegenden Zeichnungen ist der Erfiridungsgedanke in vier Ausführungsbeispielen veranschaulicht, und zwar zeigt Fig. 1 zwei Magnete, die in zwei Bügel ein- und ausschwingen, um dieselben mit Profileisen zu beladen. Fig. 2 stellt diese Bügel mit den Magneten in der Seitenansicht dar, während Fig. 3 in einem Grundriß den Antriebmechanismus erkennen läßt. Die Fig. 4, 5 und 6 veranschaulichen, in wie mannigfacher Weise die schwingende Bewegung des Magneten herbeigeführt werden kann.In the accompanying drawings, the concept of the invention is shown in four exemplary embodiments illustrates, namely Fig. 1 shows two magnets in two brackets and swing out to load the same with profile iron. Fig. 2 shows this bracket with the magnet in the side view, while Fig. 3 in a plan view of the drive mechanism reveals. Figs. 4, 5 and 6 illustrate how many times Way the oscillating movement of the magnet can be brought about.

Die Bügel α in Fig. 1 sind beispielsweise durch U-Eisenrahmen b fest verbunden, jedoch so, daß sie sich um den Punkt c drehen können. Von diesem Punkte c aus geht ein Seil oder eine Kette nach der Katze und läuft hier über eine mit einer Bremse verbundene Trommel oder Rolle d. An dem oberen Ende der Bügel befindet sich eine Rolle e, um die das Huborgan geschlungen ist. Das Hubseil f läuft auf eine Trommel g auf. Mit dieser Trommel ist das Zahnrad h fest verbunden. Dasselbe steht in Eingriff mit dem auf der Welle i lose laufenden Rade k (s. Fig. 3). Auf dieser Welle ist eine ■ Trommel I mit dem fest mit ihr verbundenen Rade m aufgekeilt. Das Rad m erhält seinen Antrieb beispielsweise durch einen Motor n. An der einen Seite läuft die Welle i in eine Spindel 0 aus. Wenn diese Spindel in drehende Bewegung versetzt wird, verschiebt sich auf ihr die Mutter ρ und nimmt nach einer gewissen Anzahl Umdrehungen mit Hilfe ihrer Klauen den Hebel r mit. Dieser steht in Eingriff mit einem zweiarmigen Hebel s, an dessen unterem Ende sich eine Rolle t befindet, die gegen das auf der Trommel / auflaufende Lastseil u des Magneten n> anliegt.The bracket α in Fig. 1 are firmly connected, for example, by U-iron frame b , but so that they can rotate about point c. From this point c , a rope or chain goes after the trolley and here runs over a drum or pulley d connected to a brake. At the upper end of the bracket there is a roller e around which the lifting element is wrapped. The hoist rope f runs onto a drum g . The gear h is firmly connected to this drum. The same is in engagement with the wheel k running loosely on the shaft i (see FIG. 3). A drum I with the wheel m firmly connected to it is keyed onto this shaft. The wheel m is driven, for example, by a motor n. The shaft i runs out into a spindle 0 on one side. When this spindle is set in rotating motion, the nut ρ shifts on it and after a certain number of revolutions takes the lever r with it with the help of its claws. This is in engagement with a two-armed lever s, at the lower end of which there is a pulley t , which rests against the load rope u of the magnet n> running onto the drum /.

Der Arbeitsgang der Einrichtung ist folgender :The operation of the facility is as follows:

Bügel und Magnet hängen von einer Katze nieder. Sie werden nunmehr in der in Fig. 1 gezeichneten Lage zu den zu verladenden Gegenständen geführt. Nachdem der Magnet n> die seiner Tragfähigkeit entsprechende Anzahl Gegenstände, beispielsweise Profileisen, angehoben hat, wird mit Hilfe des Motors κ die Trommel I in drehende Bewegung versetzt und der Magnet angehoben. Wenn der Magnet auf einer gewissen Höhe angelangt ist, beispielsweise nach drei oder vier Umdrehungen der Trommel, nimmt die Mutterp, die durchThe hanger and magnet hang down from a cat. You are now guided in the position shown in Fig. 1 to the objects to be loaded. After the magnet n> has lifted the number of objects corresponding to its load-bearing capacity, for example profile iron, the drum I is set in rotating motion with the aid of the motor κ and the magnet is raised. When the magnet has reached a certain height, for example after three or four revolutions of the drum, the nut p takes that through

Claims

this number of revolutions of the shaft i has come into engagement with the lever r, this with. The lever f strikes against the double-armed lever s and thereby the latter and with it the magnet n> are brought into the position shown in dotted lines in FIG. Has the magnet now by interrupting the current

ίο hand over the profile iron to the bracket, like this If the pawl is raised at the same time, the lever and thus the magnet return their original position and the magnet is lowered again. Then begins same movement as before. The magnet with a small load capacity is therefore loaded by frequent swinging in and out the container or bracket in question with any load.

If the brackets are sufficiently loaded and should now also be lifted, this is done by the fact that after perhaps half a turn the drum / runs onto the thread of the gear wheel k , takes it with it and thereby transfers the movement to the drum g .

If the brackets are to be unloaded elsewhere, the pivot point c is held with the aid of the brake mentioned above, but the load rope is lowered, whereby the brackets tilt out.

The inventive idea in the present invention thus lies in the oscillating movement of the magnet and this ensures that cranes with a large load capacity by magnets with a significantly lower load-bearing capacity; can be operated. The oscillating movement of the magnet itself can be achieved in many ways.

Apart from the exemplary embodiment shown in FIG. 1, FIGS. 4, 5 and 6 show some other ways.
. The way they work is as follows:

The magnet w in FIG. 4 is provided at the top with a roller ν which, when the magnet is raised, strikes against the lever s ¹ , which is rotatable about the point χ. This lever is connected by a pull rod y with another lever \ , which at one end carries a pulley t ^l , which rests against the rope on which the magnet is attached. ₍

The roller ν lifts the lever s ¹ and slides along it. By transferring the movement to the lever \ and thus to the roller i ¹ , the rope and accordingly also the magnet are guided into the bracket (see the position shown in dotted lines in FIG. 4).

In Fig. 5 the same purpose is achieved in a very simple manner by a drum q , the first gears of which have normal pitch; but if the magnet is raised to a certain height, the magnet is led sideways by a very steep incline of the drum.

Finally, according to FIG. 6, the intended purpose is achieved in that the magnet w is connected to a lifting device ² which is rotatable about the point x ¹ and which guides the magnet into the bracket when it is lifted.

Naturally, only one magnet can be used instead of the two and a closed one instead of the bracket Vessel can be used if it is, for example, ores, pigs, scrap, or scrap iron To load rivets, screws and the like.

Furthermore, the vibrating magnet can also be used for loading resistant according to the type of Paternoster works upwardly moving vessels are used by the magnet by Continuous swinging out and swinging supplies the individual containers with charge.

The same oscillating motion of the magbets can also be applied in the manner find that the magnet, for example, ores o. The like. On a conveyor belt or a corresponding Transport system leads.

From all these examples it can be seen that the inventive idea lies in the oscillating movement of the magnet, the thereby the loading of hangers, vessels, conveyor belts, etc. worried, and it "is for the invention is irrelevant in what way this oscillating movement is achieved will.

Patent-A ν SPRU ch:

A loading magnet for lifting and transport devices, characterized in that that a magnet with a low load-bearing capacity, through frequent swinging in and out, is either a bow, a vessel, a conveyor belt or the like, regardless of whether they are in motion or not, with one of their carrying capacity corresponding charge, so that despite the small carrying capacity of the magnet, the significantly larger of the no Lifting or transport device is fully utilized.
