Description

Die vorliegende Erfindung betrifft eine Kranführungsanordnung für einen Hängekran gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art. Ferner betrifft die vorliegende Erfindung einen Laufwagen der vorangehenden Kranführungsanordnung. Darüber hinaus betrifft die vorliegende Erfindung ein Kranführungsprofil der vorangehenden Kranführungsanordnung.The present invention relates to a crane guidance arrangement for a suspension crane according to the closer defined in the preamble of claim 1. Art Furthermore, the present invention relates to a carriage of the preceding crane guide assembly. Moreover, the present invention relates to a crane guide profile of the preceding crane guide assembly.

Beispielsweise aus der Druckschrift DE 103 37 122 A1 ist eine Hängekranbahn und ein Hängekranbahnprofil bekannt. Die bekannte Hängekranbahn umfasst eine Kranbahnschiene und einen an der Kranbahnschiene geführten Laufwagen. Die Kranbahnschiene besteht aus mehreren Abschnitten eines Hohlprofils, wobei der Laufwagen auf einer innerhalb des Hohlprofils gebildeten Laufbahn geführt ist. Die beiden Laufrollen eines Laufrollenpaares sind parallel zueinander angeordnet und können entlang der Laufbahn der Kranbahnschiene bewegt werden.For example, from the document DE 103 37 122 A1 is a suspension crane track and a suspension crane track profile known. The known suspension crane track comprises a crane track rail and a carriage guided on the crane track rail. The crane track rail consists of several sections of a hollow profile, wherein the carriage is guided on a track formed within the hollow profile. The two rollers of a roller pair are arranged parallel to each other and can be moved along the track of the crane track rail.

Aus der Druckschrift JP H05 319774 A ist eine Kranführungsanordnung für einen Hängekran mit einem Kranführungsprofil zur Führung eines Laufwagens mit mehreren Rollen entlang einer korrespondierenden Laufbahn im Inneren des Kranführungsprofils bekannt. Der Laufwagen weist als Rollen zwei zueinander geneigte Laufrollen auf, die im Querschnitt eine umgekehrte V-Form bilden und deren Rotationsachsen sich schneiden.From the publication JP H05 319774 A is a crane guide assembly for a suspension crane with a crane guide profile for guiding a carriage with multiple roles along a corresponding track in the interior of the crane guide profile known. The carriage has as rollers on two mutually inclined rollers, which form a reverse V-shape in cross-section and whose axes of rotation intersect.

Aus der Druckschrift JP S51 145730 U ist eine Kranführungsanordnung mit einem Kranführungsprofil zur Führung eines Laufwagens mit Rollen entlang einer korrespondierenden Laufbahn im Äußeren des Kranführungsprofils bekannt. Es hat sich gezeigt, dass bei derartigen ausgeführten Hängekranbahnen unerwünscht hohe Rollenwiderstände auftreten. Ferner können insbesondere bei länger andauernden Belastungen im Stillstand Abplattungen an den Laufrollen auftreten, welches sich negativ auf das Losbrechmoment auswirkt. Des Weiteren sind bei der bekannten Hängekranbahn weder Stütz- noch Querkräfte aufnehmbar.From the publication JP S51 145730 U is a crane guide assembly with a crane guide profile for guiding a carriage with rollers along a corresponding track in the exterior of the crane guide profile known. It has been shown that in such executed suspension crane tracks undesirably high rolling resistance occur. Furthermore, flattenings on the rollers may occur, in particular during prolonged loads at standstill, which has a negative effect on the breakaway torque. Furthermore, neither support nor transverse forces can be absorbed in the known suspension crane track.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde eine Kranführungsanordnung für einen Hängekran und einen Laufwagen sowie ein Kranführungsprofil vorzuschlagen, mit denen eine besonders einfache Handhabung und ein sicherer Betrieb ermöglicht werden.The present invention is based on the object of proposing a crane guide arrangement for a suspension crane and a carriage and a crane guide profile, with which a particularly simple handling and safe operation are possible.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 bzw. 5 bzw. 7 gelöst, wobei sich vorteilhafte Ausgestaltungen aus den jeweiligen Unteransprüchen, der Beschreibung und den Zeichnungen ergeben.This object is achieved by the features of claim 1 and 5 or 7, wherein advantageous embodiments of the respective dependent claims, the description and the drawings.

Durch die geneigte Anordnung der Laufrollen, insbesondere durch die inverse bzw. umgekehrte V-förmige Anordnung der Laufrollen im Querschnitt, ergibt sich eine hohe Präzision und Laufruhe bei der vorgeschlagenen Kranführungsanordnung.The inclined arrangement of the rollers, in particular by the inverse or inverted V-shaped arrangement of the rollers in cross-section, results in a high precision and smoothness in the proposed crane guide assembly.

Durch das Verwenden von zumindest gehärteten Oberflächen bei den Rollen und den korrespondierenden Laufbahnen ergibt sich ein optimierter Leichtlauf und ein besonders geringer Rollwiderstand. Es ist denkbar, dass metallische Laufrollen oder auch kombinierte Materialpaare zum Erhöhen der Festigkeit und zum Reduzieren des Rollwiderstandes eingesetzt werden. Beispielsweise können auch Rollen und Laufbahn aus unterschiedlichen Materialien gefertigt werden.By using at least hardened surfaces in the rollers and the corresponding raceways results in an optimized smooth running and a particularly low rolling resistance. It is conceivable that metallic rollers or combined pairs of materials are used to increase the strength and to reduce the rolling resistance. For example, rollers and raceway can be made of different materials.

Um die Übertragung von Momenten sowie von Quer- und Stützkräften in sämtlichen Achsen weiter zu verbessern, kann vorgesehen sein, dass an dem Laufwagen zusätzlich eine bezogen auf zwei einander angeordnete Laufrollenpaare zentrisch angeordnete und profilierte Führungsrolle vorgesehen ist, die entlang einer korrespondierenden Laufbahn des Kranführungsprofils geführt ist. Damit wird eine optimierte Rollengeometrie des Laufschlittens bzw. des Laufwagens ermöglicht. Neben der Führungswirkung dient die Führungsrolle auch zur Abstützung in Einbaulage nach oben, um z. B. Konterlasten abzustützen.In order to further improve the transmission of moments as well as transverse and supporting forces in all axes, it can be provided that on the carriage additionally provided with respect to two mutually arranged pairs of rollers centrically arranged and profiled guide roller is guided along a corresponding track of the crane guide profile is. This enables an optimized roller geometry of the carriage or carriage. In addition to the guiding effect, the guide roller also serves to support in the installation position upwards to z. B. support counterweights.

Die Laufrollen und die Führungsrolle sind derart zueinander angeordnet, dass sich die Wirkachse der profilierten Laufrolle und die Wirkachse der nicht profilierten Laufrolle sowie die Wirkachse der Führungsrolle in einem gemeinsamen Schnittpunkt schneiden. Mit Wirkachse ist eine entlang der Wirkkraft der jeweiligen Rolle verlaufenden Linie gemeint. Da sich die Wirkachse der Führungsrolle mit den Wirkachsen der beiden anderen geneigten Rollen kreuzt, dient die Führungsrolle nicht nur zur Führung, sondern auch zur Abstützung nach oben.The rollers and the guide roller are arranged to each other such that intersect the axis of action of the profiled roller and the axis of action of the non-profiled roller and the axis of action of the guide roller in a common point of intersection. By active axis is meant a line running along the force of action of the respective roll. As the axis of action of the guide roller crosses with the axes of action of the two other inclined rollers, the guide roller serves not only for guidance, but also for support upwards.

Eine der beiden Laufrollen ist profiliert und die andere Laufrolle glatt ausgeführt. Dadurch wird ein Los-Festlager-Modul in der Systemanbindung bewerkstelligt. Somit eignet sich die erfindungsgemäße Anordnung ideal für die Anwendung als Linearführung in der Schraubtechnik z. B. bei der Fahrzeugfertigung. Darüber hinaus ergibt sich ein Höchstmaß an Funktionalität bei zugleich kompakter Bauform.One of the two rollers is profiled and the other roller smooth. As a result, a lot fixed bearing module in the system connection is accomplished. Thus, the inventive arrangement is ideal for use as a linear guide in the screwing z. B. in vehicle production. In addition, there is a maximum of functionality with a compact design.

Die der Erfindung zu Grunde liegende Aufgabe wird auch durch einen Laufwagen der vorgeschlagenen Kranführungsanordnung gelöst. Demzufolge wird ebenfalls der separate Laufwagen mit den vor- und nachbeschriebenen Merkmalen und Vorteilen von der Erfindung beansprucht.The object underlying the invention is also achieved by a carriage of the proposed crane guide arrangement. Accordingly, the separate carriage with the advantages and advantages described above is claimed by the invention.

Die der Erfindung zu Grunde liegende Aufgabe wird auch durch ein Kranführungsprofil der vorbeschriebenen Kranführungsanordnung gelöst. Demzufolge wird auch das separate Kranführungsprofil mit den vor- und nachbeschriebenen Merkmalen und Vorteilen von der Erfindung beansprucht.The object underlying the invention is also achieved by a crane guide profile of the above-described crane guide arrangement. Accordingly, the separate crane guide profile with the advantages and advantages described above and claimed by the invention.

Im nachfolgenden wird die Erfindung anhand der Zeichnungen weiter erläutert. Es zeigen:

  • Figur 2 eine dreidimensionale Ansicht eines Kranführungsprofils;
  • Figur 3 eine Seitenansicht des entlang der Laufbahnen des Kranführungsprofils geführten Laufwagens;
  • Figur 4 Eine dreidimensionale Ansicht gemäß Figur 3; und
  • Figur 5 eine mögliche weitere Ausführungsvariante der Kranführungsanordnung für einen Hängekran.
In the following the invention will be further explained with reference to the drawings. Show it:
  • FIG. 1 a possible embodiment of a crane guide assembly with a movably mounted in a crane guide rail carriage;
  • FIG. 2 a three-dimensional view of a crane guidance profile;
  • FIG. 3 a side view of the run along the raceways of the crane guide profile carriage;
  • FIG. 4 A three-dimensional view according to FIG. 3 ; and
  • FIG. 5 a possible further embodiment of the crane guide arrangement for a suspension crane.

In den Figuren 1 bis 5 sind verschiedene Ansichten einer Kranführungsanordung für einen Hängekran beispielhaft dargestellt.In the FIGS. 1 to 5 various views of a Kranführungsanordung for a suspension crane are exemplified.

Die Kranführungsanordung umfasst zumindest ein Kranführungsprofil 1 zur Führung zumindest eines Laufwagens 11 bzw. Fahrwerkkörpers mit mehreren Rollen, die jeweils entlang korrespondierender Laufbahnen des Kranführungsprofils geführt sind. Der Laufwagen 11 weist erfindungsgemäß zwei zueinander geneigte Laufrollen 8, 9 auf.The crane guidance arrangement comprises at least one crane guide profile 1 for guiding at least one carriage 11 or chassis body with a plurality of rollers which are respectively guided along corresponding raceways of the crane guidance profile. The carriage 11 according to the invention has two mutually inclined rollers 8, 9.

Wie insbesondere aus Figur 1 ersichtlich ist, bilden die geneigten Laufrollen 8, 9 im Querschnitt etwa eine umgekehrte V-Form, wobei sich die Rotationssachsen der Laufrollen 8, 9 schneiden. Die in Figur 1 auf der linken Seite dargestellte Laufrolle 8 dient als schwimmende Laufrolle des Fahrwerkes bzw. des Laufwagens, da diese eine glatte, nicht profilierte Oberfläche aufweist. Die rechte Laufrolle 9 dient als profilierte Laufrolle des Laufwagens und führt diesen.As in particular from FIG. 1 it can be seen, the inclined rollers 8, 9 in cross-section approximately an inverted V-shape, wherein the rotational axes of the rollers 8, 9 intersect. In the FIG. 1 shown on the left side roller 8 serves as a floating roller of the chassis or the carriage, since it has a smooth, non-profiled surface. The right-hand roller 9 serves as a profiled roller of the carriage and guides it.

Wie insbesondere aus den Figuren 3 und 4 ersichtlich ist, weist der Laufwagen mehrere in Bewegungsrichtung hintereinander angeordnete Laufrollenpaare auf, wobei jedes Laufrollenpaar zwei zueinander geneigte Laufrollen 8, 9 umfasst. Zur verbesserten Führung und auch zur Aufnahme von so genannten Konterlasten umfasst der Laufwagen 11 eine bezogen auf die beiden Laufrollenpaare zentrisch angeordnete und profilierte Führungsrolle 10, welche auch als profilierte Gegendruckrolle des Laufwagens 11 bezeichnet werden kann. Die Führungsrolle 10 wird entlang einer korrespondierenden Laufbahn des Kranführungsprofils 1 geführt.As in particular from the Figures 3 and 4 can be seen, the carriage has a plurality of pairs of rollers arranged one behind the other in the direction of movement, wherein each pair of rollers comprises two mutually inclined rollers 8, 9. For improved guidance and also for the reception of so-called counter-loads, the carriage 11 comprises a guide roller 10 which is centrally arranged and profiled relative to the two pairs of rollers and which can also be referred to as a profiled counterpressure roller of the carriage 11. The guide roller 10 is guided along a corresponding track of the crane guide profile 1.

Gemäß Figur 1 ist angedeutet, dass die Laufrollen 8, 9 und die Führungsrolle 10 derart zueinander angeordnet sind, dass sich die Wirkachse A der Laufrollen 9 und die Wirkachse B der Laufrolle 8 sowie die Wirkachse C der Führungsrolle 10 in einem gemeinsam Punkt D schneiden. Demzufolge ergibt sich eine so genannte X Anordnung bzw. Ausrichtung der Wirkachsen A und B.According to FIG. 1 is indicated that the rollers 8, 9 and the guide roller 10 are arranged to each other such that intersect the effective axis A of the rollers 9 and the active axis B of the roller 8 and the active axis C of the guide roller 10 in a common point D. As a result, a so-called X arrangement or alignment of the effective axes A and B results.

Die Führungsrolle 10 ist in axialer Richtung, also horizontal, schwimmend gelagert und in der senkrechten Achse bzw. Hochachse, also in Richtung der Wirkachse C, zum Beispiel durch eine Führungsgabel einstellbar oder auch federnd gelagert. Mit diesen Maßnahmen werden zum Beispiel Produktionstoleranzen bei den Kranführungsprofilen 1 kompensiert.The guide roller 10 is mounted in the axial direction, ie horizontally, floating and in the vertical axis or vertical axis, ie in the direction of the axis of action C, for example, by a guide fork adjustable or spring mounted. With these measures, for example, production tolerances in the crane guide profiles 1 are compensated.

Die vorgeschlagene Kranführungsanordnung ist vorzugsweise für Leichtkransysteme für Handhabungsgeräte einsetzbar. Der Laufwagen 11 bzw. Laufschlitten ist durch die schräg angestellten, sich kreuzenden Laufrollen 8, 9 und der zentrisch angeordneten oberen Führungsrolle 10 gekennzeichnet, wobei anstelle von üblicherweise weichen Materialien für die Rollen der Einsatz von harten, z. B. metallischen oder auch anderen gehärteten Materialien vorgesehen ist.The proposed crane guide arrangement is preferably used for light crane systems for handling equipment. The carriage 11 or carriage is characterized by the obliquely employed, intersecting rollers 8, 9 and the centrally arranged upper guide roller 10, wherein instead of usually soft materials for the roles of the use of hard, z. B. metallic or other hardened materials is provided.

Als Laufbahnen bzw. -flächen sind, wie insbesondere aus Figur 2 ersichtlich ist, Laufbahnprofile oder Stangenprofile 2 vorgesehen. Beispielsweise können diese Stangenprofile 2 als gehärtete Wellen oder dergleichen ausgeführt werden, wodurch eine leichtgängige, präzise Linearführung erreicht wird.As raceways or surfaces are, as in particular from FIG. 2 it can be seen, career profiles or bar profiles 2 provided. For example, these bar profiles 2 can be made as hardened shafts or the like, whereby a smooth, precise linear guide is achieved.

Die Stangenprofile 2 sind gemäß Figur 1 und 2 in das Kranführungsprofil 1 eingebettet. Auf diese Weise wird neben der vorteilhaften leichtgängigen Bewegung des Laufwagens 11 zudem das Kranführungsprofil 1 mechanisch versteift, so dass eine als z. B. Aluminium-Extrusionsprofil ausgeführte biegesteife Kranschiene insbesondere für den Einsatz im Leichtkranbereich realisiert wird. Beispielsweise können die Stangenprofile 2 formschlüssig, reibschlüssig, kraftschlüssig oder dergleichen mit dem Kranführungsprofil 1 verbunden werden. Beispielsweise können mehrere Kranführungsprofile 1 hintereinander angeordnet werden und über die Nuten 7 mit entsprechenden Nutensteinen 24 gemäß Figur 5 miteinander verbunden werden.The bar profiles 2 are according to FIG. 1 and 2 embedded in the crane guide profile 1. In this way, in addition to the advantageous smooth movement of the carriage 11 also the crane guide profile 1 is mechanically stiffened, so that a z. B. aluminum extrusion profile executed rigid crane rail is realized in particular for use in light crane sector. For example, the bar profiles 2 can be positively, frictionally, non-positively or the like connected to the crane guide profile 1. For example, several crane guide profiles 1 can be arranged one behind the other and via the grooves 7 with corresponding sliding blocks 24 according to FIG. 5 be connected to each other.

Zur axialen Verlängerung kann bei jedem Stangenprofile 2 vorgesehen sein, dass mehrere Stangenprofile 2 hintereinander in Bewegungsrichtung des Laufwagens 11 angeordnet werden. Zur Realisierung einer exakten Verbindung an den Stößen von zwei hintereinander angeordneten Stangenprofilen 2 können entsprechend formschlüssige miteinander korrespondierende Elemente vorgesehen sein, wie zum Beispiel an einer Seite ein Zentrierdorn und an der anderen Seite ein korrespondierender Innenkonus oder dergleichen. Die Stangenprofile 2 an jedem Ende können mit Endkappen oder dergleichen versehen sein, die zum Beispiel mittels federnden Druckstücken oder dergleichen dafür sorgen, dass die dazwischenliegenden Stangenprofile 2 an deren Stößen nahezu spaltfrei aneinander gedrückt werden. Diese Maßnahme führt zu einem ruckfreiem Verhalten beim Überfahren durch den Laufwagen 11.For axial extension can be provided with each bar profiles 2 that a plurality of bar profiles 2 are arranged one behind the other in the direction of movement of the carriage 11. To realize an exact connection to the joints of two bar profiles 2 arranged one behind the other, correspondingly positive elements corresponding to each other can be provided, for example a centering pin on one side and a corresponding inner cone or the like on the other side. The bar profiles 2 at each end can be provided with end caps or the like, which ensure, for example by means of resilient pressure pieces or the like, that the intermediate bar profiles 2 are pressed against each other at their joints almost gap-free. These Measure leads to a jerk-free behavior when driving over the carriage 11.

Gemäß Figur 1 und 2 können die Stangenprofile 2 für die Laufrollen 8, 9 und die Führungsrolle 10 im Querschnitt etwa in Dreiecksform in dem Schienenkörper bzw. Kranführungsprofil 1 angeordnet sein. Vorzugsweise kann jedes Stangenprofil 2 eine etwa kreisförmige Querschnittsform aufweisen. Es sind aber auch andere Querschnittsformen denkbar.According to FIG. 1 and 2 the bar profiles 2 for the rollers 8, 9 and the guide roller 10 may be arranged in cross-section approximately in triangular shape in the rail body or crane guide profile 1. Preferably, each bar profile 2 may have an approximately circular cross-sectional shape. But there are also other cross-sectional shapes conceivable.

Aus Figur 3 ist ferner ersichtlich, dass an dem Laufwagen 11 eine Achse 12 oder dergleichen zur Aufnahme von Lasten oder Geräten vorgesehen ist. Ferner weist der Laufwagen 11 an jedem Ende einen Anschlagpuffer 13 auf.Out FIG. 3 It can also be seen that on the carriage 11, an axle 12 or the like is provided for receiving loads or devices. Furthermore, the carriage 11 has a stop buffer 13 at each end.

In Figur 5 ist beispielhaft eine weitere Ausführungsvariante einer erfindungsgemäßen Kranführungsanordung bzw. eines linearen Kranführungsprofils dargestellt. Die Kranführungsanordung umfasst zunächst zwei parallel zueinander ausgerichtete Kranführungsprofile 1, die jeweils direkt über eine Flanschplatte 31 einer Trägerklemme 20 an einer beliebigen Trägerstruktur, z. B. einem Stahlträger 21 einer Deckenaufhängung oder eines bewegbaren Portals, befestigt sind. Es ist auch möglich, dass die Kranführungsprofile 1 jeweils über ein weiteres Bauteil, wie zum Beispiel ein Aufsatzprofil zur mechanischen Versteifung, an der Flanschplatte 31 der Trägerklemme 20 an dem Stahlträger 21 befestigt sind. Die Laufwagen 11 der beiden Kranführungsprofile 1 sind an einem quer zu den beiden Kranführungsprofilen 1 ausgerichteten weiteren Kranführungsprofil bzw. Kranbrückenprofil 19 befestigt. Das Kranbrückenprofil 19 kann manuell oder automatisch über einen Antrieb z. B. als optionaler Zahnriemenantrieb bewegt werden, wobei an dem nicht weiter dargestellten Laufwagen des Kranbrückenprofils 19 eine Last oder Geräte anbringbar sind.In FIG. 5 By way of example, a further embodiment variant of a crane guidance arrangement according to the invention or a linear crane guidance profile is shown. The crane guide assembly initially comprises two parallel crane guide profiles 1, each directly via a flange plate 31 of a support clamp 20 to any support structure, for. B. a steel beam 21 a ceiling mount or a movable portal, are attached. It is also possible that the crane guide profiles 1 are each attached to the steel support 21 via a further component, such as an attachment profile for mechanical reinforcement, on the flange plate 31 of the support clamp 20. The carriages 11 of the two crane guide profiles 1 are fastened to a further crane guide profile or crane bridge profile 19 aligned transversely to the two crane guide profiles 1. The crane bridge profile 19 can manually or automatically via a drive z. B. be moved as an optional belt drive, wherein on the not shown carriage of the crane bridge profile 19, a load or equipment can be attached.

Als Koppelung zwischen dem Kranbrückenprofil 19 und dem Zahnriemenantrieb 22 ist ein Mitnehmer 23 einerseits an dem Zahnriemenantrieb 22 und andererseits an dem Kranbrückenprofil 19 befestigt. Um eine leichtgängige Bewegung des Kranbrückenprofils 19 zu ermöglichen, ist eine schwimmende Kranbrückenprofilanbindung 25 und eine starre Kranbrückenprofilanbindung 26 vorgesehen. Die Energieversorgung wird durch eine Mitnehmerplatte 15 zum Beispiel als Stromabnehmer realisiert, der mit einem Schleifleitungsprofil 17 in Verbindung steht.As coupling between the crane bridge profile 19 and the toothed belt drive 22, a driver 23 is fastened on the one hand to the toothed belt drive 22 and on the other hand to the crane bridge profile 19. In order to enable a smooth movement of the crane bridge profile 19, a floating crane bridge profile connection 25 and a rigid crane bridge profile connection 26 is provided. The energy supply is realized by a driver plate 15, for example, as a current collector, which communicates with a conductor rail profile 17.

Die Trägerklemmen 20 weisen Konstruktionsmerkmale zum Ausgleich von Winkelfehlern in beide Bewegungsrichtungen bzw. -achsen auf. Dies ist erforderlich, wenn zum Beispiel der Stahlträger 21 nicht waagerecht montiert ist oder in der Querachse schräg montierte Flanschplatten 31 aufgrund von Herstellungstoleranzen vorgesehen sind.The carrier clamps 20 have design features to compensate for angular errors in both directions of movement or axes. This is necessary if, for example, the steel girder 21 is not mounted horizontally or obliquely mounted flange plates 31 are provided in the transverse axis due to manufacturing tolerances.
