Description

Selbsttätig aufwickelnde Kabeltrommel für ortsveränderliche elektrische Maschinen Wo die Stromzuführung für ortsveränderliche elektrische Maschinen durch ein biegsames Kabel (beispielsweise Gummischlauchleitung) erfolgt, verwendet man zum Schutz des. Kabels Trommeln, die selbsttätig die jeweils freien Kabellängen aufnehmen. Die Betätigung erfolgte bisher entweder durch Federantrieb, Gewichtsantrieb oder durch mechanische Kupplung mit dem Fahrwerk.Self-winding cable reel for portable electrical ones Machines Where the power supply for portable electrical machines through a flexible cable (e.g. rubber hose line) is used to protect the. Cable drums, which automatically adjust the free cable lengths take up. Up to now, it has been operated either by a spring drive or a weight drive or by mechanical coupling with the chassis.

Der Federantrieb ist in seiner Anwendung beschränkt auf verhältnismäßig kurze Kabellängen geringen Querschnittes. Für den Gewichtsantrieb ist Voraussetzung ein genügend langer Gegengewichtsweg und die Möglichkeit der räumlichen Anordnung. Bei direkter Kupplung mit dem Fahrwerk ist es vielfach schwierig, eine genaue Übereinstimmung des Fahrwerkes mit der Länge des notwendig abzuwickelnden Kabels herzustellen, insbesondere beispielsweise für Raupenbagger, die an keinen bestimmten Weg gebunden sind.The spring drive is limited in its application to relative short cable lengths with a small cross-section. A prerequisite for the weight drive a sufficiently long counterweight path and the possibility of spatial arrangement. In the case of direct coupling with the chassis, it is often difficult to achieve an exact match of the chassis with the length of the necessary cable to be unwound, in particular for example, for crawler excavators that are not tied to a specific route.

Gegenstand der Erfindung ist- eine Kabeltrommel, die zwecks Erzeugung eines Momentes im Sinne der Aufwicklung des Kabels mit einem Elektromotor verbunden ist, der ständig eingeschaltet bleibt. Der Motor entwickelt dabei ein dauerndes Moment und wikkelt das bei der Bewegung des Fahrzeuges jeweils frei werdende Kabel auf. Das sich straffende -Kabel überwindet schließlich das Motormoment und bringt den Motor zum Stehen. Voraussetzung für eine betriebssichere Arbeitsweise ist natürlich, daß der Motor den Stillstandstrom beliebig lange aushalten kann, ohne daß er infolge übermäßiger Erwärmung zerstört wird. Für Drehstrom finden Motore, die dieser Voraussetzung entsprechen, als Motorbremslüfter bereits V er-Wendung. Dort benutzt man den Motor, um eine Kurbel zu drehen, an der das Bremsgewicht hängt. In der obersten Stellung der Kurbel wird die Bewegung des Motors abgebremst, und der Motor entwickelt im Stillstand dauernd das zur Lüftung des Bremsgewichtes erforderliche Moment. Bei Gleichstrom müßte sinnentsprechend die Stromaufnahme des stillstehenden Motors durch Vorschalten eines Widerstandes so weit begrenzt werden, daß keine unzulässige Erwärmung eintritt.The object of the invention is a cable drum, which for the purpose of production a moment in the sense of winding the cable connected to an electric motor that stays on all the time. The engine develops a constant Moment and winds the cable that becomes free as the vehicle moves on. The tightening cable finally overcomes the engine torque and brings the engine to a standstill. The prerequisite for safe working is of course, that the motor can withstand the standstill current as long as desired without it as a result excessive heating is destroyed. For three-phase current, there are motors that meet this requirement correspond, as an engine brake fan already U turn. There you use the engine to turn a crank on which the braked weight hangs. In the top position the crank brakes the movement of the motor, and the motor develops in the Standstill the torque required to release the braked weight. at Direct current would have to correspond to the current consumption of the stationary motor Upstream of a resistor can be limited to such an extent that no inadmissible heating entry.

In Verbindung mit der Kabeltrommel bleibt der Motor gleichfalls dauernd eingeschaltet und entwickelt ein seinem Drehsinn entsprechendes Moment auf den Trommelkörper im Sinne einer Aufwicklung des Kabels. Entfernt sich die Kabeltrommel von der Anschlußstelle, und muß infolgedessen das freie Kabel länger werden, so wird durch den Zug am Kabel das; Motormament überwunden, und der Motor wird, entgegen dem seiner Schaltung entsprechenden Drehsinne, durchgezogen.In connection with the cable drum, the motor also remains constant switched on and develops a moment on the drum body that corresponds to its sense of rotation in the sense of winding the cable. If the cable drum moves away from the connection point, and if the free cable has to become longer as a result, the pull on the cable will cause it the; Motormament overcome, and the motor is, contrary to its circuit corresponding Sense of rotation, drawn through.

Auf diese Weise wird erreicht, daß die Kabeltrommel eine beliebige Anzahl von Umdrehungen machen kann und somit für die größten Kabellängen ausreicht. Ferner wird das Gegengewicht mit seinen störenden Begleiterscheinungen vermieden, andererseits ist es sicher, daß nur die jeweils erforderliche Länge des Kabels von der Trommel abgerollt werden kann.In this way it is achieved that the cable drum any Number of revolutions and is therefore sufficient for the largest cable lengths. Furthermore, the counterweight with its annoying side effects is avoided, on the other hand, it is certain that only the required length the cable can be unwound from the drum.

Die Zeichnung zeigt in Abb. i die Vorderansicht, in Abb. a die Seitenansicht einer Anordnung, bei welcher der Erfindungsgedanke benutzt wird. Die Trommel i dient zur Aufnahme des 'aufzuwickelnden Kabels und ist mit dem Zahnrad z auf einer gemeinsamen Welle befestigt. Am Umfang des Zahnrades z greift das Ritzel 3 des Elektromotors 4 an und übt auf das Zahnrad a und die Trommel i ein Moment zur Aufwicklung des Kabels aus. Damit die Kraftäußerung möglichst stoßfrei auf das Kabel übertragen wird, ist der Motor 4 auf einer Traverse 5 gleichfalls drehbar um die Welle befestigt. Die Traverse 5 wird durch die Federn 6 in. ihrer Mittellage festgehalten. Bei einer Bewegung der Trommel wird eine der Federn 6 aul Druck beansprucht und bildet somit ein elastisches Zwischenglied. Auf diese Weise wird beim Einschalten eine sanfte Kraftübertragung auf die Trommel erzielt und andererseits kurz vor dem Stillstand des Motors ein geaiigender Weg freigegeben, auf welchem die lebendige Kraft des Motorankers vernichtet werden kann.The drawing shows in Fig. I the front view, in Fig. A the side view an arrangement in which the inventive concept is used. The drum i serves to accommodate the 'to be wound up cable and is on a common with the gear z Shaft attached. The pinion 3 of the electric motor engages on the circumference of the gearwheel z 4 and exerts a moment on the gear a and the drum i to wind up the Cable. So that the expression of force is transmitted to the cable as smoothly as possible is, the motor 4 is also rotatably mounted on a cross member 5 around the shaft. The traverse 5 is held in place by the springs 6 in its central position. At a Movement of the drum, one of the springs 6 is subjected to pressure and thus forms an elastic intermediate member. This way, when you turn it on it becomes a gentle one Power transmission achieved on the drum and on the other hand shortly before the standstill of the engine released a suitable way in which the living power of the Motor armature can be destroyed.
