Abstract

The invention refers to a hanging control device connected to a unit to be managed, specifically control switches or hanging control panels in order to control hoisting gear, by means of a control line, whereby the control line contains electrical lines ( 2 ) to transmit control signals and strain relief, which is supported at the top of the unit to absorb weight and traction forces. In order to create a hanging control device for which the length of the control line can be easily changed, we suggest that strain relief be created by means of hose ( 6 ), which can be folded flat and has the design of a type of textile hose, and that electrical lines ( 2 ) run through the inside of the hose.

Description

HängesteuereinrichtungSuspension control device
Beschreibungdescription
Die Erfindung betrifft eine Hängesteuereinrichtung, die über eine Steuerleitung an einer zu steuernden Einheit hängt, insbesondere Steuerschalter oder Hängetaster zum Steuern eines Hebezeugs, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a suspension control device which hangs on a unit to be controlled via a control line, in particular control switches or suspension buttons for controlling a hoist, according to the preamble of claim 1.
Hängesteuereinrichtungen in Form eines Hängetasters sind beispielsweise aus der EP 0 592 795 A1 und der DE-OS 26 03 409 bekannt, welche zum Steuern der Auf- und Abbewegung eines oberhalb einer Bedienperson befindlichen Hebezeugs dienen. Die Hängetaster weisen ein Gehäuse auf, an dem eine Reihe von Schalttasten angeordnet sind. Das Schaltgehäuse ist an seinem oberen Ende über ein Verbindungskabel mit dem Hebezeug verbunden. Das Verbindungskabel weist eine Hülle auf, in der die elektrische Steuerleitung zur Übertragung von Steuersignalen und eine Zugentlastung in Form eines Stahlseils oder eines Metallkabels angeordnet sind. Die Zugentlastung dient zur Aufnahme von Gewichts- und Zugkräften und ist oben am Hebezeug befestigt. Zugkräfte entstehen insbesondere dann, wenn die Bedienperson quer am Schaltgehäuse zieht, um das an einem Träger verfahrbare Hebezeug zu verschieben. Hierzu kann am Schaltgehäuse ein entsprechender Handgriff vorgesehen sein. Andererseits kann auch die Hülle selbst aus einem festen Kunststoff bestehen, so dass sie der Bedienperson zusätzlich als Griffelement dienen kann.Hanging control devices in the form of a hanging button are known, for example, from EP 0 592 795 A1 and DE-OS 26 03 409, which serve to control the up and down movement of a hoist located above an operator. The pendant switches have a housing on which a number of switching buttons are arranged. The switch housing is connected to the hoist at its upper end via a connecting cable. The connecting cable has a sheath in which the electrical control line for transmitting control signals and a strain relief in the form of a steel cable or a metal cable are arranged. The strain relief is used to absorb weight and tensile forces and is attached to the top of the hoist. Tractive forces arise in particular when the operator pulls transversely on the switch housing in order to move the lifting device which can be moved on a carrier. For this purpose, a corresponding handle can be provided on the switch housing. On the other hand, the cover itself can also consist of a solid plastic, so that it can also serve as an grip element for the operator.
Der Nachteil der bekannten Hängesteuereinrichtungen besteht darin, überhaupt nicht verlängerbar zu sein. Möglich ist lediglich ein Kürzen des Kabels, was zudem aufwendig ist. Häufig wird versucht, trotz der schlechteren Bedienbarkeit mit der einmal gewählten Länge des Verbindungskabels auszukommen.The disadvantage of the known suspension control devices is that they cannot be extended at all. It is only possible to shorten the cable, which is also is complex. It is often attempted to make do with the length of the connecting cable that has been selected, despite the poorer usability.
Die Aufgabe der Erfindung ist es, eine Hängesteuereinrichtung anzugeben, bei der die Steuerleitung mit geringem Aufwand in seiner Länge veränderbar ist.The object of the invention is to provide a suspension control device in which the length of the control line can be changed with little effort.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die Unteransprüche enthalten vorteilhafte Ausgestaltungen der Hängesteuereinrichtung.The object is solved by the features of claim 1. The subclaims contain advantageous configurations of the hanging control device.
Die Lösung sieht vor, dass die Zugentlastung aus einem flach zusammenlegbarenThe solution provides that the strain relief from a flat collapsible
Schlauch nach Art eines Textilschlauchs gebildet ist und die elektrischen Leitungen durch das Schlauchinnere verlaufen. Erst durch die Verwendung eines solchen "textilen" Schlauchs ist es möglich, den Teil der Steuerleitung, der für die erforderliche Länge nicht benötigt wird, zusammen mit den elektrischen Leitungen platzspa- rend abzulegen, ohne auf eine wirksame Zugentlastung und eine gute Greifbarkeit der Steuerleitung, insbesondere zum Ziehen der zu steuernden Einheit, verzichten zu müssen.Hose is formed in the manner of a textile hose and the electrical lines run through the hose interior. It is only through the use of such a "textile" hose that it is possible to save the part of the control line that is not required for the required length together with the electrical lines in a space-saving manner, without effective strain relief and good grip of the control line, especially to pull the unit to be controlled, without having to.
Ein geringes Speichervolumen ergibt sich, wenn der Schlauch zusammen mit den elektrischen Leitungen im Speicher gefaltet ablegbar ist, d.h. im Längs- und Quervolumen gefaltet.A small storage volume results if the hose can be stored folded together with the electrical lines in the storage, i.e. folded in the longitudinal and transverse volume.
Die Greifbarkeit der Steuerleitung verbessert sich, wenn der Schlauch im Griffbereich der Bedienperson mit einem elastischen Material ausgefüllt ist.The tangibility of the control line is improved if the hose in the grip area of the operator is filled with an elastic material.
Konstruktiv einfach ist es, wenn das elastische Material einen längsgeschlitzten Hohlzylinder bildet, durch dessen Hohlraum die elektrischen Leitungen oder das Kabel, wen diese ein solches bilden, verlaufen.It is structurally simple if the elastic material forms a longitudinally slotted hollow cylinder, through the cavity of which the electrical lines or the cable, if these form such a, run.
Alternativ ist es auch möglich, dass der Schlauch im Griffbereich der Bedienperson durch einen Hohlzylinder aus einem elastischen Material geführt ist.Alternatively, it is also possible for the hose to be guided through a hollow cylinder made of an elastic material in the grip area of the operator.
Eine kostengünstige Lösung sieht vor, dass das elastische Material aus einem Schaumstoff gebildet ist. Um eine lange Lebensdauer des Schlauchs sicherzustellen, wird vorgeschlagen, dass die Abstützung des Schlauchs an der Einheit über eine Abstützeinrichtung erfolgt, welche die Gewichts- und Zugkräfte gleichmäßig auf den Schlauchumfang verteilt.An inexpensive solution provides that the elastic material is formed from a foam. In order to ensure a long service life of the hose, it is proposed that the hose be supported on the unit by means of a support device which distributes the weight and tensile forces evenly over the circumference of the hose.
Eine einfache und wirksame Abstützeinrichtung ist aus einem innerhalb des Schlauchs angeordneten Kegelstumpf mit einer Durchgangsöffnung für die elektrischen Leitungen und einem außerhalb des Schlauchs angeordneten und an der Einheit abgestützten Innentrichter gebildet, der zur Kegelstumpfaußenform korres- pondiert, wobei der Kegelstumpf durch die Gewichts- und Zugkräfte in den Trichter gezogen wird und so den Schlauch an der Einheit axial festlegt.A simple and effective support device is formed from a truncated cone arranged inside the hose with a through opening for the electrical lines and an inner funnel arranged outside of the hose and supported on the unit, which corresponds to the outer shape of the truncated cone, the truncated cone due to the weight and tensile forces is pulled into the funnel and thus axially fixes the hose to the unit.
Alternativ ist es vorteilhaft, wenn der Trichter Teil der Einheit ist.Alternatively, it is advantageous if the funnel is part of the unit.
Zur einfachen Montage wird vorgeschlagen, dass der Kegelstumpf und der Trichter jeweils längsgeteilt und aus zwei zusammensteckbaren Hälften gebildet sind.For simple assembly, it is proposed that the truncated cone and the funnel are each longitudinally divided and formed from two halves that can be plugged together.
Um die Festlegung des Schlauchs an der Einheit lösen zu können, wird vorgeschlagen, dass die Abstützeinrichtung ein Element aufweist, mit dem der Kegelstumpf durch Eindrücken des Schlauches von außen nach oben schiebbar ist, wozu dasIn order to be able to solve the fixing of the hose to the unit, it is proposed that the support device have an element with which the truncated cone can be pushed upwards by pushing the hose in, which is why
Element mit nach innen gerichteten den Kegelstumpf untergreifenden Nasen versehen ist.Element is provided with inwardly directed lugs under the truncated cone.
Zweckmäßigerweise weist der Trichter eine Längsführung für das außen verschieb- bare Element auf.The funnel expediently has a longitudinal guide for the externally displaceable element.
Zur Aufnahme der nicht benötigten Steuerleitung wird vorgeschlagen, dass von der Hängesteuereinrichtung zur Einheit gesehen hinter der Abstützeinrichtung ein Speicher für die elektrischen Leitungen vorgesehen ist.To accommodate the control line that is not required, it is proposed that, seen from the hanging control device to the unit, a memory for the electrical lines is provided behind the support device.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand einer Zeichnung beschrieben. Es zeigen:An embodiment of the invention is described below with reference to a drawing. Show it:

Fig. 1 zeigt eine Übertragungseinheit 1 einer Hängesteuereinrichtung für die Steuersignale einer zu steuernden Einheit (beide nicht gezeigt), wobei die Hängesteuereinrichtung bezogen auf Fig. 1 unten an der Steuerleitung 1 befestigt ist. Bei der Hän- gesteuereinrichtung kann es sich um einen Steuerschalter mit einer Reihe von1 shows a transmission unit 1 of a suspension control device for the control signals of a unit to be controlled (neither of which is shown), the suspension control device being attached to the control line 1 at the bottom with reference to FIG. 1. The hanging control device can be a control switch with a series of
Tastern handeln, die z.B. zur Auf- und Abbewegung eines Hebezeugs dienen.Actuate buttons that e.g. serve to move a hoist up and down.
Die Steuerleitung 1 weist elektrische Leitungen 2 in Form eines Kabels 3 auf, an dessen Enden jeweils elektrische Stecker 4, 5 befestigt sind. Die elektrischen Lei- tungen 2 in Form eines Kabels 3 dienen der Übertragung von Steuersignalen von der Hängesteuereinrichtung zu der zu steuernden Einheit, hier also dem Hebezeug. Vom Kabel 3 mit den elektrischen Leitungen 2 ist in Fig. 1 nur der unteren Teil dargestellt. Neben dem Kabel 3 umfasst die Steuerleitung 1 eine Zugentlastung in Form eines flach zusammenlegbaren Schlauchs 6 nach Art eines Textilschlauchs. Der Schlauch 6 kann wie ein Textilschlauch aus gewebtem oder geflochtenem Textil bestehen. Bei dem Textilmaterial kann es sich um Kunststoff als auch um natürliche Textilstoffe handeln. Der Außendurchmesser des Kabels 3 verhält sich zum Innendurchmesser des Schlauchs 6 mindestens wie 1 :3, hier 1 :5. Der Schlauch 6 ist oben an der Einheit über eine Abstützeinrichtung 7 abgestützt, die aus einem Kegel- stumpf 8 und einem dazu korrespondierenden (lnnen-)Trichter 9 gebildet wird, wobei sich der Kegelstumpf 8 im Innern des Schlauchs 6 befindet. Mittels eines Elements 10 lässt sich der Kegelstumpf 8 von außen relativ zum feststehenden Trichter 9 etwas nach oben verschieben, um die Verbindung zwischen dem Schlauch 6 und der Einheit wieder zu lösen. Im Griffbereich 11 der Bedienperson befindet sich innerhalb des Schlauchs 6 ein Hohlzylinder 12, der aus einem festen elastischenThe control line 1 has electrical lines 2 in the form of a cable 3, at the ends of which electrical plugs 4, 5 are each attached. The electrical lines 2 in the form of a cable 3 are used to transmit control signals from the hanging control device to the unit to be controlled, in this case the lifting device. Only the lower part of the cable 3 with the electrical lines 2 is shown in FIG. 1. In addition to the cable 3, the control line 1 includes a strain relief in the form of a flat foldable hose 6 in the manner of a textile hose. The hose 6 can consist of a woven or braided textile like a textile hose. The textile material can be plastic as well as natural textile materials. The outside diameter of the cable 3 relates to the inside diameter of the hose 6 at least as 1: 3, here 1: 5. The tube 6 is supported on the top of the unit by a support device 7, which is formed from a truncated cone 8 and a corresponding (inner) funnel 9, the truncated cone 8 being located inside the tube 6. By means of an element 10, the truncated cone 8 can be displaced somewhat upwards from the outside relative to the fixed funnel 9 in order to release the connection between the hose 6 and the unit again. In the grip area 11 of the operator there is a hollow cylinder 12 inside the hose 6, which is made of a solid elastic
Material besteht und so einen festen Griff und gleichzeitig einen Schutz der elektrischen Leitungen 2 bildet; das feste elastische Material kann sich auch über die gesamte untere Schlauchlänge erstrecken. Die elektrischen Leitungen 2 verlaufen durch dessen Durchgangsöffnung hindurch, wobei ein Längsschlitz 13 ein leichteres Einbringen der elektrischen Leitungen 2 bzw. des Kabels 3 in den Hohlzylinder ermöglicht. Im Griffbereich 11 der Bedienperson ist der Schlauch 6 mit einem elastischen Material ausgefüllt. Bei dem elastischen Material handelt es sich um einen elastischen Schaumstoff mit entsprechender Festigkeit.Material consists and so forms a firm grip and at the same time protects the electrical lines 2; the solid elastic material can also extend over the entire lower hose length. The electrical lines 2 run through its through opening, a longitudinal slot 13 making it easier to insert the electrical lines 2 or the cable 3 into the hollow cylinder. In the grip area 11 of the operator, the hose 6 is with a filled in elastic material. The elastic material is an elastic foam with appropriate strength.
Die gesamte Zugentlastung zur Aufnahme der auftretenden Gewichts- und Zugkräfte erfolgt allein über den Schlauch 6.The entire strain relief for absorbing the occurring weight and tensile forces takes place solely via the hose 6.
Alternativ kann der Schlauch 6 mit dem innen verlaufenden Kabel 3 aber auch selbst durch einen Hohlzylinder aus einem elastischen Material verlaufen, das also den Schlauch 6 auch außen umgeben kann.Alternatively, the hose 6 with the cable 3 running inside can also run itself through a hollow cylinder made of an elastic material, which can therefore also surround the hose 6 on the outside.
Fig. 2 zeigt eine teilgeschnittene Seitenansicht der Steuerleitung 1 ; Fig. 3 zeigt die zugehörige Vorderansicht. Insbesondere lässt Fig. 2 das von unten nach oben durchgehende Kabel 3 mit den Leitungen 2 erkennen, die im oberen Bereich zusammen mit dem umgebenden Schlauch flach zusammengelegt und gefaltet sind und so einen Kabelspeicher 14 bilden.Fig. 2 shows a partially sectioned side view of the control line 1; Fig. 3 shows the associated front view. In particular, FIG. 2 shows the cable 3, which runs from bottom to top, with the lines 2, which are folded flat and folded together with the surrounding hose in the upper region and thus form a cable store 14.
Weiter zeigt Fig. 2 die Abstützeinrichtung 7 in Funktion, wobei die Gewichts- und Zugkräfte gleichmäßig auf den Schlauchumfang verteilt werden. So befindet sich der aus den beiden Hälften gebildete Kegelstumpf 8 innerhalb des Schlauchs 6. Seine Verschiebbarkeit nach unten ist durch den Trichter 9 und nach oben durch eine Nase 15 (s. Fig. 1 ) am Trichter 9 begrenzt. Wie Fig. 1 zeigt, ist das Element 10 im Trichter 15 mittels der Führungszapfen 10a geführt. Der Trichter 9 ist fest an der Einheit, also dem Hebezeug, abgestützt, so dass bei auftretenden Zugkräften der Kegelstumpf 8 nach unten gezogen wird, wodurch der Schlauch wiederum bezogen auf den Trichter 9 axial festgelegt wird. Die Kegelstumpfform muss dabei selbstverständlich mit dem Innentrichter des Trichters 9 korrespondieren. Auf diese Weise werden Gewichts- und Zugkräfte gleichmäßig auf den Schlauchumfang verteilt.FIG. 2 also shows the support device 7 in operation, the weight and tensile forces being distributed uniformly over the circumference of the hose. Thus, the truncated cone 8 formed from the two halves is located within the tube 6. Its downward displaceability is limited by the funnel 9 and upwards by a nose 15 (see FIG. 1) on the funnel 9. As shown in FIG. 1, the element 10 is guided in the funnel 15 by means of the guide pins 10a. The funnel 9 is firmly supported on the unit, that is to say the hoist, so that the truncated cone 8 is pulled down when tensile forces occur, as a result of which the hose is in turn axially fixed in relation to the funnel 9. The truncated cone shape must of course correspond to the inner funnel of the funnel 9. In this way, weight and tensile forces are evenly distributed over the circumference of the hose.
Der Kegelstumpf 8 ist mit einer Durchgangsöffnung 16 versehen, durch die das Ka- bei 3 mit den elektrischen Leitungen 2 lose hindurchverläuft. Wird das Element 10 nach oben geschoben, nimmt es den Kegelstumpf 8 durch den Schlauch 6 hindurch mit, so dass die Verbindung zwischen Kegelstumpf 8 und Trichter 9 wieder gelöst wird. Dann ist es möglich, Schlauch 6 mit dem Kabel 3 aus dem Speicher 14 von oben nachzulassen und bei nach oben geschobenem Kegelstumpf 8 durch die Ab- Stützeinrichtung 7 hindurch nach unten durchzuziehen, wodurch eine einfache Verlängerung des Steuerkabels 1 möglich ist. Umgekehrt kann auf diese Weise das Steuerkabel 1 auch verkürzt werden.The truncated cone 8 is provided with a through opening 16 through which the cable 3 with the electrical lines 2 runs loosely. If the element 10 is pushed upwards, it takes the truncated cone 8 through the hose 6, so that the connection between the truncated cone 8 and the funnel 9 is released again. It is then possible to let the hose 6 with the cable 3 from the reservoir 14 drop from above and pull it down through the support device 7 when the truncated cone 8 is pushed upwards, so that the control cable 1 can be easily extended. Conversely, the control cable 1 can also be shortened in this way.
Fig. 4 zeigt den Speicher 14 noch einmal in einer vergrößerten Darstellung. Fig. 4 shows the memory 14 again in an enlarged view.
