Description

Technisches Gebiet der ErfindungTechnical field of the invention

Diese Erfindung bezieht sich auf eine Anlage zur Steuerung von Kränen von der Art, die eine auf einem Rahmen vorgesehenen, äußeren Schutzkappe aufweist, hinter welcher mehrere Steuerkomponentenkästen untergebracht sind, welche durch Entfernen der Schutzkappe von außen zugänglich sind.This invention relates to a system for controlling cranes of the type comprising a frame provided on an outer protective cap, behind which a plurality of control box components are housed, which are accessible by removing the cap from the outside.

Stand der TechnikState of the art

Die Steuerung von fahrzeuggetragenen Kränen erfolgt gewöhnlicherweise mit Hilfe von zwei Steueranlagen oder -aggregaten, die auf entgegengesetzten Seiten des Fahrzeuges im Bereich hinter der Fahrerkabine gelegen sind. Jede Anlage weist einen Satz von Hydraulventilen auf, deren Funktion von einer der Anzahl von Ventilen entsprechenden Anzahl von vom Hand betätigtbaren Betätigungshebeln bestimmt wird. Verschiedene Funktionen des Kranes, wie Drehung des Kranpfeilers, heben bzw. senken von einem oder mehreren Kranarmen, Drehung eines Rostators, Einspielen von einem Windehaken u.s.w., können durch Steuerung der Ventile aktiviert werden. Steueranlagen dieser Art sind durch SE 8201833-4 bekannt. Die Steueranlagen sind normalerweise mit einem im wesentlichen U-förmigen Bügel versehen, welcher den Satz von Betätigungshebeln allseitig umschließt, um den Satz von Betätigungshebeln zu schützen, sodaß diese nicht unabsichtlich aktiviert werden, z.B. durch einen nicht geplanten Körperkontakt.The control of vehicle-mounted cranes usually takes place with the aid of two control systems or units located on opposite sides of the vehicle in the area behind the driver's cab. Each plant has a set of hydraulic valves whose function is determined by a number of valves corresponding to the number of manually operated control levers. Various functions of the crane, such as rotation of the crane pillar, raising or lowering of one or more crane arms, rotation of a ram, loading of a hoist hook, etc., can be activated by controlling the valves. Control systems of this type are through SE 8201833-4 known. The control systems are normally provided with a substantially U-shaped bracket which surrounds the set of operating levers on all sides to protect the set of operating levers so that they are not inadvertently activated, eg by unplanned body contact.

Entsprechend dem Oberbegriff des Anspruchs 1 ist aus der WO 96/24551 ein Steuergerät für Kräne bereits bekannt, in welchem mehrere Betätigungshebeln auf einem schwenkbar gelagerten Träger angeordnet sind. Die Betätigungshebeln sind hinter einer geteilten Schutzkappe untergebracht und zusammen mit der Schutzkappe zwischen einer eingeklappten Ruhestellung, in welcher die Schutzkappe den Träger sowie dazu gehörende Betätigungshebeln einschließen kann, und einer ausgeklappten Gebrauchslage in welcher die Betätigungshebeln durch öffnen die Schutzkappe von außen zugänglich sind, schwenkbar. Vorkommendenfalls; anders gestalteten Steuereinheiten kann auf dem Träger oder auf der Schutzkappe angeordnet sein.According to the preamble of claim 1 is from the WO 96/24551 a control device for cranes already known, in which a plurality of actuating levers are arranged on a pivotally mounted carrier. The operating levers are housed behind a split cap and together with the cap between a retracted rest position in which the cap can include the carrier and associated operating levers, and a deployed position in which the operating levers are accessible by opening the cap from the outside, pivotally. Vorkommendenfalls; differently designed control units can be arranged on the support or on the protective cap.

Viele von den heutigen, modernen Kränen sind außerdem mit einer gesonderten Funkausrüstung versehen, welche Fernbedienung der Kräne ermöglicht. Mit anderen Worten kann der Kran entweder vom Hand mit Hilfe von Betätigungshebeln oder durch Funktechnik über eine Fernbedienungsvorrichtung wahlweise gesteuert werden. Die verschiedenen Elektronikbauteile, die zu der Funkausrüstung gehören, werden im Anschluß zu der einen der beiden entgegensetzten Steueranlagen (gewöhnlicherweise auf der Fahrerseite des Fahrzeuges) montiert. DieMany of today's modern cranes are also equipped with separate radio equipment that allows remote control of the cranes. In other words, the crane can be selectively controlled either manually by means of operating levers or by radio technology via a remote control device. The various electronic components associated with the radio equipment are mounted subsequent to one of the two opposing control systems (usually on the driver's side of the vehicle). The

Elektronikbauteile oder -komponente sind in einzelnen, kleinen Kästen angeordnet, welche im Bereich oberhalb des Satzes von Hydraulventilen angeordnet werden, und zwar in einem Raum, der nach außen von einem Gehäuse, zu welchem wenigstens eine abnehmbare Kappe gehört, geschützt wird.Electronic components or component are arranged in individual, small boxes, which are arranged in the area above the set of hydraulic valves, in a space which is protected from the outside of a housing, to which at least one removable cap belongs.

Bei den bereits bekannten Steueranlagen sind die Elektronikkomponentenkästen auf einem Rahmen, der das Schutzgehäuse und dessen abnehmbare Kappe trägt, fest montiert. Die praktische Herstellung von Kränen mit Steueranlagen von der beschriebenen Art erfolgt in einer Herstellungslinie, entlang welcher die verschiedenen Teile, die zu dem Kran gehören, nacheinander entlang der Linie montiert werden, bevor der fertige Kran eine Schlußprüfungsstation erreicht.In the already known control systems, the electronic component boxes are fixedly mounted on a frame supporting the protective housing and its removable cap. The practical manufacture of cranes with control systems of the type described is carried out in a production line along which the various parts belonging to the crane are successively mounted along the line before the finished crane reaches a final inspection station.

Die Tatsache, daß die obengenannten Elektronikkomponentenkästen auf dem dazugehörenden Rahmen innerhalb des Schutzgehäuses fest montiert sind, ruft Nachteile nicht nur in Verbindung mit der Herstellung des Kranes hervor, aber ebenfalls in Verbindung mit Wartung an späteren Zeitpunkten. Eine hohe Anzahl von Kabeln erstrecken sich zwischen den verschiedenen Elektronikkomponentenkästen. Würde ein Fehler in den Elektronikkomponenten oder den Kabeln entstehen, wird der Vorgang zur Beseitigung des Fehlers aufwendig und zeitraubend, weil die Räume zwischen den Kästen und deren Tragblechen eng und schwer zugänglich sind. Würde ein Fehler in Verbindung mit der Schlußprüfung des Kranes und dessen Steueranlage entdeckt werden, dann entsteht ein kostspieliges Anhalten in der Produktionskette. Entsteht der Fehler in Verbindung mit der Arbeit des Kranes auf dem Arbeitsfeld, könnte eine Beseitigung des Fehlers zu erheblichen Problemen führen, z.B. wenn ein einzelner Elektronikkomponentenkasten entfernt und durch einen anderen Kasten ersetzt werden muss.The fact that the aforementioned electronic component boxes are fixedly mounted on the associated frame within the protective housing, causes disadvantages not only in connection with the manufacture of the crane, but also in connection with maintenance at later times. A high number of cables extend between the various electronic component boxes. If a fault would arise in the electronic components or the cables, the process for eliminating the error becomes costly and time-consuming, because the spaces between the boxes and their support plates are narrow and difficult to access. If a mistake were discovered in connection with the final inspection of the crane and its control system, then a costly halt in the production chain arises. If the error arises in connection with the work of the crane in the field of work, elimination of the error could lead to considerable problems, e.g. when a single electronic component box needs to be removed and replaced with another box.

Detaillierte Beschreibung einer bevorzugten Ausführungsform der ErfindungDetailed description of a preferred embodiment of the invention

Zu der auf den Zeichnungen gezeigten Anlage gehört ein als Ganzer mit 1 bezeichneter Rahmen, der die Aufgabe hat mehrere kleine Elektronikkomponentenkästen 2, 3 zu tragen. Die Anlage umfaßt weiterhin zwei Schutzkappen, von welchen eine Erste mit 4 und eine Zweite mit 5 bezeichnet sind. Der Rahmen 1 weist zwei seitlich beabstandete Seitenstücke 6 auf, welche über ein Querstück 7 miteinander verbunden sind. Dieses Querstück 7 ist auf zwei Pfosten 8 angebracht, welche unten in einen als Ganzer mit 9 bezeichneten Bügel von der Art, die als Aufgabe hat Betätigungshebel zu schützen, übergehen. In diesem Zusammenhang ist darauf hinzuweisen, daß die gezeigte Anlage in der Tat oben auf einem nicht gezeigten Satz von Hydraulventilen montiert wird, wobei die Ventile zu dem Hydraulsystem des Kranes gehören und durch im Raum innerhalb des Bügels 9 angebrachte Betätigungshebel vom Hand beeinflussbar sind. Diese Betätigungshebel sind ebenfalls auf den Zeichnungen nicht gezeigt. Es sollte auch erwähnt werden, daß vorkommende Kabel zwischen den verschiedenen Kästen 2, 3 aus Deutlichkeitsgründen auf den Zeichnungen nicht gezeigt worden sind.To the system shown in the drawings belongs as a whole with 1 designated frame, which has the task to carry several small electronic component boxes 2, 3. The system further comprises two protective caps, of which a first with 4 and a second with 5 are designated. The frame 1 has two laterally spaced side pieces 6, which are connected to each other via a cross piece 7. This crosspiece 7 is mounted on two posts 8, which pass down into a designated as a whole with 9 bracket of the kind that has as a task to protect operating lever. In this regard, it should be noted that the system shown is indeed mounted on top of a set of hydraulic valves, not shown, the valves belonging to the hydraulic system of the crane and being influenced by hand in the space inside the bracket 9 operating lever. These operating levers are also not shown in the drawings. It should also be noted that any cables between the various boxes 2, 3 have not been shown on the drawings for clarity.

Gekennzeichnend für die Erfindung ist, daß wenigstens einige Elektronikkomponentenkästen, nämlich die mit 2 bezeichneten Kästen, auf einem lösbaren, gesonderten Träger 10 vorgesehen sind, welcher zwischen einer gegen den Rahmen 1 eingeklappten Gebrauchslage (siehe Fig.2), in welcher die Schutzkappe 4 den Träger sowie die Kästen einschließt, und einer weg von dem Rahmen ausgeklappten Lage zu Wartungszwecke (siehe Fig. 5) schwenkbar ist. In dem Beispiel besteht der Träger 10 aus einer im wesentlichen rechteckigen Platte mit zwei in einem Winkel gestellten, versteifenden Seitenflanschen 11, die ihrerseits über Gelenke 12 mit dem Bügel verbunden sind. Der Bügel 9 ist aus zwei parallelen Schenkeln 9' und einem Vorderstück 9" gebildet. Auf jedem von den Schenkeln 9' ist ein Ohr 13 mit einem Loch für das Gelenk 12 angebracht. Dieses Gelenk kann auseinander genommen werden und aus einem einfachen Bolzen mit dazugehörender Mutter bestehen. Durch Entfernen der beiden Gelenkbolzen von den dazugehörenden Löchern in den Ohren 13 bzw. den Seitenflanschen 11, kann somit der Träger 10 von dem Bügel 9 entfernt werden.Characteristic of the invention is that at least some electronic component boxes, namely the boxes designated 2, are provided on a detachable, separate carrier 10, which is folded between a folded against the frame 1 use position (see Figure 2), in which the cap 4 the Carrier includes and the boxes, and a folded away from the frame position for maintenance purposes (see Fig. 5) is pivotable. In the example, the carrier 10 consists of a substantially rectangular plate with two angled, stiffening side flanges 11, which in turn are connected by joints 12 to the bracket. The bracket 9 is formed of two parallel legs 9 'and one front piece 9 ", on each of the legs 9' there is attached an ear 13 with a hole for the hinge 12. This hinge can be disassembled and made of a simple bolt with associated bolt Mother by removing the two hinge pin of the corresponding holes in the ears 13 and the side flanges 11, thus the carrier 10 can be removed from the bracket 9.

Wie es aus z.B. Fig. 5 hervorgeht, ist ein oder mehrere Elektronikkomponentenkästen 2 auf jeder der beiden entgegengesetzten Seiten der Trägerplatte 10 montiert.As it is made of e.g. 5, one or more electronic component boxes 2 are mounted on each of the two opposite sides of the carrier plate 10.

Die Trägerplatte 10 ist mit Vorteil über einen Winkel von mindestens 90° zwischen der eingeklappten Lage gemäß Fig. 2 und einer ausgeklappten Lage gemäß Fig. 5 schwenkbar. In der eingeklappten Lage ist die Trägerplatte 10 in einer Vertikalebene gelegen, in welcher sie durch geeignete Mittel festgehalten wird, z.B. Schrauben (nicht gezeigt), die in Sitzen 14 in den Pfosten 8 festgezogen werden. In einem Winkel gestellte Endabschnitte 15 sind auf den Ohren 13 ausgeführt, um die Trägerplatte in der ausgeklappten Endlage zu halten und gegen welche untere Kanten auf den Seitenflanschen 11 anliegen können. In Fig. 5 wird die Trägerplatte 10 nicht in ihrer unteren Endlage gezeigt, sondern in einer horisontalen Zwischenlage, aus welcher die Trägerplatte nach unten mit etwa 10°-20° geschwenkt werden kann, bevor die Seitenflansche in Berührung mit den herausgebogenen Endabschnitten 15 der Ohren kommen.The support plate 10 is pivotally with advantage over an angle of at least 90 ° between the folded position shown in FIG. 2 and a folded-out position shown in FIG. 5. In the folded position, the support plate 10 is located in a vertical plane in which it is held by suitable means, e.g. Screws (not shown), which are tightened in seats 14 in the post 8. Angled end portions 15 are made on the ears 13 to hold the support plate in the deployed end position and against which lower edges on the side flanges 11 can rest. In Fig. 5, the support plate 10 is not shown in its lower end position, but in a horisontalen intermediate position from which the support plate can be pivoted downwards at about 10 ° -20 ° before the side flanges in contact with the bent-out end portions 15 of the ears come.

Die erste, vordere Kappe 4 wird im montierten Zustand mittels geeigneter Kupplungsmittel 16 festgehalten, z.B. Spannhaken oder Gummibänder. An ihren unteren Enden weist die Kappe 4 herausragende Abschnitte 4' auf, welche den Hauptteil der beiden Schenkel 9' des Bügels 9 decken. Auf den Schenkeln sind Manschetten 17 angebracht, in welche die Enden der herausragenden Abschnitte 4' der Kappe hineingesteckt sind zur Festlegung der Kappe. In einer Vorderwand der Kappe 4 ist eine Öffnung 18 herausgenommen, in welcher die Stirnwände von zwei Elektronikkomponentenkästen 2 bloßgelegt sind. Entfernen der Kappe 4 erfolgt durch die einfache Maßnahme die Kupplungsmittel 16 zu lösen und die Kappe aus den Manschetten 17 herauszuziehen.The first, front cap 4 is held in the mounted state by means of suitable coupling means 16, for example, tensioning hooks or rubber bands. At its lower ends, the cap 4 on outstanding portions 4 ', which cover the main part of the two legs 9' of the bracket 9. On the legs cuffs 17 are mounted, in which the ends of the protruding portions 4 'of the cap are inserted for fixing the cap. In a front wall of the cap 4, an opening 18 is taken out, in which the end walls of two electronic component boxes 2 are exposed. Removing the cap 4 is carried out by the simple measure to release the coupling means 16 and remove the cap from the sleeves 17.

Auch die hintere, zweite Kappe 5 ist mit dem Rahmen 1 lösbar verbunden, z.B. über einen Schraubverband. Die mit 3 bezeichneten Komponentenkästen sind in dem Beispiel auf einer gemeinsamen, vertikalen Trägerplatte 18 vorgesehen, welche zwischen den Seitenstücken 6 des Rahmens aufgehängt sind. In Abhängigkeit der Länge dieser Seitenstücke 6 können mehrere Kastensätze sowie Trägerplatten nacheinander in dem Raum zwischen den Seitenstücken montiert werden. Wie die schwenkbare Trägerplatte 10 ist die Trägerplatte 18 lösbar angeordnet, um ein einfaches Entfernen des Kastensatzes 3 zu erlauben, z.B. zu Wartungs- oder Prüfungszwecke.Also, the rear, second cap 5 is detachably connected to the frame 1, e.g. over a screw connection. The component boxes designated 3 are provided in the example on a common, vertical support plate 18, which are suspended between the side pieces 6 of the frame. Depending on the length of these side pieces 6, a plurality of sets of catches and support plates can be successively mounted in the space between the side pieces. Like the pivotable support plate 10, the support plate 18 is releasably disposed to allow easy removal of the box set 3, e.g. for maintenance or testing purposes.

Es ist ein grundlegender Vorteil der erfindungsgemäßen Anlage, daß ein oder mehrere Sätze von Elektronikkomponentenkästen sich in wenigstens einer getrennten Einheit neben der gewöhnlichen Herstellungslinie für den Kran zusammensetzen lassen. Die ganze Arbeit in Verbindung mit der Montierung und Funktionsprüfung der Kästen kann deshalb mit den Kästen leicht zugänglich und unabhängig von dem Zeitdruck, der in der Herstellungslinie für die Kräne herrscht, durchgeführt werden. Weiterhin wird vorkommende Wartung nach angefangenen Gebrauch des Kranes weitgehend erleichtert. Durch die Tatsache, daß die Trägerplatte 10 für die Elektronikkomponentenkästen 2 in beschriebener Weise klappbar ist, werden somit die Kästen auf sowohl der Stirnseite als auch der Rückseite der Trägerplatte leicht zugänglich, auch in dem Falle, daß die Trägerplatte auf dem Bügel oder dem Rahmen zurückbleibt. Wird eine umfangreiche Wartung erfordert, ist es dazu möglich, die Trägerplatte vom Bügel zu lösen und die ganze Komponentenkasteneinheit durch eine neue Einheit zu ersetzen. Die hintere Einheit von Komponentenkästen 3 wird weiterhin bequem zugänglich nach der vorderen Trägerplatte 10 zu ihrer ausgeklappten Lage geschwenkt worden ist. Auch die hintere Komponentenkasteneinheit kann von dem Rahmen entfernt werden, wenn umfangreiche Wartungsarbeiten erfordert werden.It is a fundamental advantage of the system according to the invention that one or more sets of electronic component boxes can be assembled in at least one separate unit besides the usual manufacturing line for the crane. All the work in connection with the assembly and functional testing of the boxes can therefore be carried out with the boxes easily accessible and independent of the time pressure prevailing in the manufacturing line for the cranes. Furthermore, occurring maintenance after the use of the crane is largely facilitated. By the fact that the support plate 10 for the electronic component boxes 2 in the manner described is hinged, thus the boxes on both the front side and the back of the support plate are easily accessible, even in the event that the support plate remains on the bracket or the frame , If extensive maintenance is required, it is possible to release the carrier plate from the bracket and replace the entire component box unit with a new unit.
