Here, the safeguard may, for example, make use of a pivoting armature (15, 115).

Description

Elektrischer Hubankermagnet Electric lifting armature magnet
Die Erfindung betrifft einen elektrischen Hubankermagneten gemäß dem Oberbegriff des Anspruches 1The invention relates to an electrical lifting armature magnet according to the preamble of claim 1
Elektrische Hubankermagnete mit einer auf einem Spulenkorper angeordneten Magnetspule und einem in der Magnetspule verschiebbar angeordneten Hub¬ anker sind allgemein bekannt In der Regel erfolgt die Verschiebung des Hub¬ ankers nach außen durch die Krafteinwirkung einer koaxial zum Hubanker angeordneten Ruckstel lfeder Die Bewegung des Hubankers ins Innere der Magnetspule erfolgt dadurch, daß die magnetische Anziehungskraft der Mag¬ netspule auf den Hubanker infolge des durch Stromfluß aufgebauten Magnet¬ feldes die Federkraft der Ruckstell feder übersteigt.Electrical lifting armature magnets with a magnetic coil arranged on a coil body and a lifting armature displaceably arranged in the magnetic coil are generally known. As a rule, the lifting armature is displaced outward by the force of a spring spring arranged coaxially to the lifting armature. The movement of the lifting armature into the interior the magnetic coil is achieved in that the magnetic attraction force of the magnetic coil on the lifting armature exceeds the spring force of the return spring due to the magnetic field built up by current flow.
Ein derartiger Hubankermagnet ist insbesondere aus der DE 40 30 514 C2 bekannt Der in dieser Druckschrift beschriebene Hubankermagnet weist die oben beschriebene Anordnung von Spulenkorper, Magnetspule, Hubanker und Ruckstellfeder auf Dabei hat der Hubanker an seinem freien Ende eine kolben¬ artige Verdickung, die bei Stromfluß vollständig aus der Langsbohrung im Spulenkorper ragt Aufgrund eines mechanischen Spiels zwischen Ankerbolzen und Magnetanker ermögl icht eine von außen auf das System einwirkende, radial auf den Ankerbolzen gerichtete Kraft das Verkippen desselben gegenüber dem Magnetanker und der Magnetspule, sofern der Ankerbolzen ausgefahren ist. Infolge einer Hinterschneidung bei der kolbenartigen Verdickung bleibt der Ankerbolzen am Rand der Bohrung derart hängen, daß auch bei einer Unter¬ brechung des Stromflusses zu der Magnetspule der Ankerbolzen trotz der dann noch vorhandenen Wirkung der Rückstellfeder in seiner ausgefahrenen Stellung verbleibt. Wird die Kraft aufgehoben, so wird der Ankerbolzen durch die Rückstellkraft der Rückstellfeder in das Innere der Magnetspule hineingezogen . Dies geschieht aufgrund der zentrierenden Wirkung der Rückstel lfeder und einer Hohlelementdichtung, die außerhalb der Bohrung angeordnet ist.Such a lifting armature magnet is known in particular from DE 40 30 514 C2. The lifting armature magnet described in this document has the above-described arrangement of coil body, solenoid coil, lifting armature and return spring. The lifting armature has at its free end a piston-like thickening which occurs when current flows protrudes completely from the longitudinal hole in the coil former due to a mechanical play between anchor bolts and magnet armature enables a force acting externally on the system and directed radially onto the armature bolt to tilt it relative to the magnet armature and the solenoid coil if the armature bolt is extended. As a result of an undercut in the piston-like thickening, the armature bolt remains stuck to the edge of the bore in such a way that, even when the current flow to the magnetic coil is interrupted, the armature bolt remains in its extended position despite the then remaining effect of the return spring. If the force is released, the armature bolt is drawn into the interior of the magnet coil by the restoring force of the restoring spring. This is due to the centering effect of the return spring and a hollow element seal which is arranged outside the bore.
Nachteil einer derartigen Anordnung ist, daß ein Verklemmen oder Selbsthem¬ mung n icht sicher vermieden wird. Ferner ist eine externe Kraft für das Verkip¬ pen des Ankerbolzens erforderlich.The disadvantage of such an arrangement is that jamming or self-locking is not reliably avoided. Furthermore, an external force is required to tilt the anchor bolt.
Es ist Aufgabe der vorliegenden Erfindung, einen elektrischen Hubankermagne¬ ten zu schaffen, bei dem diese Nachteile sicher vermieden werden. Ferner soll der Hubanker vibrationsfest sein, wobei der Hubankermagnet in ausgefahrenem Zustand sicher verriegelt sein soll.It is an object of the present invention to provide an electrical lifting armature in which these disadvantages are reliably avoided. Furthermore, the lifting armature should be vibration-resistant, the lifting armature magnet should be securely locked in the extended state.
Diese Aufgabe wird durch einen Hubankermagneten mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by a lifting armature magnet with the features of claim 1.
Das Vorsehen einer Sicherung erhöht die Sicherheit gegen axiales Verschieben des Hubankers infolge äußerer Krafteinwirkungen. Da keine in eine bestimmte Richtung wirkende externe Kraft für das Eingreifen der Sicherung erforderl ich ist, ist das System beliebig einsetzbar. Eine unerwünschte axiale Bewegung des Hubankers infolge äußerer Kräfte wird durch die Sicherung beispielsweise durch Verriegeln des Hubankers verhindert. Eine radiale Bewegung ist infolge der Fuhrung des Hubankers n icht möglich.The provision of a fuse increases the security against axial displacement of the lifting anchor as a result of external forces. Since no external force acting in a certain direction is required to intervene, the system can be used as required. An undesired axial movement of the lifting armature as a result of external forces is prevented, for example prevented by locking the lifting anchor. A radial movement is not possible due to the guidance of the lifting armature.
Besonders vortei lhaft ist das zeitliche Veisetzen der Bewegung der Sicherung zur Bewegung des Hubankers. Dies schließt unter anderem eine gegenseitige Beh inderung aus.The temporal setting of the movement of the safety device to the movement of the lifting anchor is particularly advantageous. Among other things, this excludes mutual hindrance.
Durch eine oder mehrere im Gehäuse vorgesehene Ausnehmungen kann durch die Schwächung des magnetischen Flusses die o.g. zeitliche Reihenfolge ver¬ ändert werden Insbesondere wird dadurch auch eine Verriegelung im erregten Zustand, also bei eingezogenem Hubanker möglich. Der elektr ische Hubanker¬ magnet ist somit sehr flexibel einsetzbar. Die Einbindung der Sicherung in das System des magnetischen Flusses durch den Hubanker hat zudem den Vortei l, daß wenige zusätzliche Teile für die Sicherung benotigt werden. Der Huban- kermagπet ist daher kostengünstig und zuverlässig.Through one or more recesses provided in the housing, the above-mentioned can be achieved by weakening the magnetic flux. The chronological order can be changed. In particular, this also enables locking in the excited state, that is to say when the lifting armature is retracted. The electrical lifting armature magnet can thus be used very flexibly. The integration of the fuse in the system of magnetic flux through the lifting anchor also has the advantage that a few additional parts are required for the fuse. The lifting armature magnet is therefore inexpensive and reliable.
Vorteilhaft ist ferner die Ausgestaltung der Sicherung als Klappanker Dabei kann der Klappanker als Teil des Gehäuses ausgebi ldet sein Dies hat den Vortei l, daß der Klappanker gleichzeitig den magnetischen Fluß gut leitet, wodurch das magnetische Feld entsprechend verstärkt wird Die auf den Hubanker wirkende Kraft wird dadurch verstärkt und der Hubanker wird siche¬ rer in seiner eingezogenen Stellung gehalten.It is also advantageous to design the fuse as a hinged anchor. The hinged anchor can be formed as part of the housing. This has the advantage that the hinged anchor simultaneously conducts the magnetic flux well, which increases the magnetic field accordingly. The force acting on the lifting anchor becomes thereby reinforced and the lifting armature is held securely in its retracted position.
Besonders unempfindlich gegenüber Vibrationen ist ein Klappanker, der entlang einer Achse, die parallel zur Langsachse des Hubankers verlauft, verschwenk¬ bar ist. Aufgrund der unterschiedlichen Bewegungsrichtungen wird die Sicher¬ heit der Verriegelung erheblich erhöht.A folding anchor is particularly insensitive to vibrations and can be pivoted along an axis that runs parallel to the longitudinal axis of the lifting anchor. Due to the different directions of movement, the security of the locking is increased considerably.
Vorteilhaft ist der teilweise Eingriff des Klappankers in eine im Hubanker vor¬ gesehene Ausnehmung. Dabei ist die Ausnehmung vorzugsweise eine umlau- fende Nut. Dies stellt den sicheren Eingriff auch bei verdrehtem Hubanker sicher.The partial engagement of the hinged anchor in a recess provided in the lifting anchor is advantageous. The recess is preferably a circumferential fende groove. This ensures safe engagement even when the lifting anchor is twisted.
Im folgenden wird die vorl iegende Erfindung anhand zweier Ausfuhrungsbei- spiele unter Bezugnahme auf die beiliegenden Zeichnungen naher erläutert. Es zeigen:The present invention is explained in more detail below on the basis of two exemplary embodiments with reference to the accompanying drawings. Show it:

In der Magnetspule 5 ist ein Hubanker 7 entlang seiner Langsachse (X-Richtung) verschiebbar in einer Ausnehmung 8 angeordnet. Die Fuhrung des Hubankers 7 erfolgt auf einer ersten Seite 9 mittels eines stangenartigen Fort¬ satzes 10, der durch eine im Gehäuse 4 vorgesehene Bohrung 1 1 ragt. Auf der gegenüberl iegenden zweiten Seite 1 2 erfolgt die Fuhrung mittels einer zweiten im Gehäuse 4 vorgesehenen Bohrung 1 3, durch die der Hubankermagnet 1 teilweise herausragt. Auf der ersten Seite 9 des Hubankers 7 ist koaxial zur Langsachse des Hubankers 7 eine Rückstellfeder 1 4 vorgesehen, die den Anker 7 belastet. Dabei wird die Ruckstellfeder 14 durch den stangenartigen Fortsatz 10 des Hubankers 7, der durch sie hindurch ragt, gefuhrt.1 shows an electrical lifting armature magnet 1. The lifting armature magnet 1 has a housing 4 with a magnet coil 5 arranged on a coil body. A lifting armature 7 is arranged in the magnet coil 5 in a recess 8 along its longitudinal axis (X direction). The lifting armature 7 is guided on a first side 9 by means of a rod-like extension 10 which projects through a bore 11 provided in the housing 4. On the opposite second side 1 2, the guidance takes place by means of a second bore 1 3 provided in the housing 4, through which the lifting armature magnet 1 partially protrudes. On the first side 9 of the lifting armature 7, a return spring 1 4 is provided coaxially to the longitudinal axis of the lifting armature 7 and loads the armature 7. The return spring 14 is guided through the rod-like extension 10 of the lifting armature 7, which projects through it.
Der Hubankermagnet 1 weist ferner eine Sicherung 3 in Form eines Klappan¬ kers 1 5 auf, der auf seiner einen Seite 1 7 mit Hilfe eines Bolzens 19 schwenk- bar am Gehäuse 4 angebracht ist Auf der der Seite 1 7 gegenüberliegenden Seite 21 ist der Klappanker 1 5 um 90° abgewinkelt und weist eine Bohrung 23 auf, deren Durchmesser etwas großer als der Durchmesser des Hubankers 7 ist. In der Nahe des abgewinkelten Teils stutzt sich der Klappanker 1 5 am Gehäuse 4 mittels einer Druckfeder 25 abThe lifting armature magnet 1 also has a fuse 3 in the form of a hinged armature 15 which is pivoted on one side 17 with the aid of a bolt 19. bar is attached to the housing 4 on the side 21 opposite to the side 17, the hinged armature 15 is angled by 90 ° and has a bore 23, the diameter of which is somewhat larger than the diameter of the lifting armature 7. In the vicinity of the angled part, the hinged anchor 15 is supported on the housing 4 by means of a compression spring 25
Bei der in Fig 1 dargestel lten ausgefahrenen und verriegelten Stellung des Hubankers 7 erfolgt das Ausfahren aufgrund der Ruckstellfeder 14, die den Hubanker 7 teilweise aus der Bohrung 1 3 herausschiebt Die Verriegelung erfolgt mit Hi lfe des Klappankers 1 5 H ierfür weist der Hubanker 7 an seiner zweiten Seite 1 2 eine Ausnehmung 27 aut, die im Ausfuhrungsbeispiel eine umlaufende N ut bildet Autgrund der Vorspannung der Druckfeder 25 greift der Rand der im abgewinkelten Tei l des Klappankers 1 5 vorgesehenen Bohrung 23 in die Ausnehmung 27 und verriegelt dadurch den Hubanker 7 in dieser ausge¬ fahrenen StellungIn the extended and locked position of the lifting armature 7 shown in FIG. 1, the extension takes place due to the return spring 14, which partially pushes the lifting armature 7 out of the bore 1 3. The locking is done with the aid of the folding armature 1 5 its second side 1 2 has a recess 27 which, in the exemplary embodiment, forms a circumferential groove due to the pretension of the compression spring 25, the edge of the hole 23 provided in the angled part of the hinged armature 1 5 engages in the recess 27 and thereby locks the lifting armature 7 in this extended position
Erfolgt eine Erregung des Hubankermagneten 1 infolge eines Stromflusses, so wird zuerst der Klappanker 1 5 entgegen der Kraft der Druckfeder 25 angezogen (Y-Richtung) und gibt die Verriegelung des Hubankers 7 trei Autgrund des durch den Klappanker 1 5 vergrößerten Joches wird das Magnetfeld verstärkt Hat sich ein ausreichend großes Magnetfeld aufgebaut, so wird als zweite Stufe der Hubanker 7 entgegen der Vorspannung der Ruckstellfeder 14 in die Aus¬ nehmung 8 hineingezogen (X-Richtung) Dieser Zustand ist in Fig 2 dargestelltIf the lifting armature magnet 1 is excited as a result of a current flow, the folding armature 15 is first attracted against the force of the compression spring 25 (Y direction) and the locking of the lifting armature 7 is due to the yoke enlarged by the folding armature 15, the magnetic field is strengthened If a sufficiently large magnetic field has built up, the lifting armature 7 is drawn into the recess 8 against the bias of the return spring 14 as a second stage (X direction). This state is shown in FIG. 2
Gemäß einem zweiten Ausfuhrungsbeispiel, das in Fig. 3 dargestellt ist, erfolgt die Verriegelung des Hubankers 1 07 mit Hi lfe einer Sicherung 1 03 in Form eines Klappankers 1 1 5, der um eine Achse geschwenkt wird, die parallel zur Langsachse des Hubankers 107 verlauft. Die erforderliche Vorspannung wird durch eine Druckfeder 1 25 aufgebaut, die außen am Gehäuse 104 zwischen einem Fortsatz 1 30 des Klappankers 1 1 5 und einem Winkel 1 31 , der am Gehäuse 104 angebracht ist, befestigt ist. Für die Verriegelung ist am Klappan¬ ker 1 1 5 ein Arm 1 32 vorgesehen, der in ausgefahrenem Zustand in eine um¬ laufende Ausnehmung 127 des Hubankers 107 eingreift.According to a second exemplary embodiment, which is shown in FIG. 3, the lifting armature 1 07 is locked with the aid of a fuse 1 03 in the form of a folding armature 1 1 5, which is pivoted about an axis which runs parallel to the longitudinal axis of the lifting armature 107 .
