Description

Profil für Tieflöffel- und Ladeschaufelausrüstungen eines Baggers sowie Verfahren zur Herstellung desselben Profile for backhoe and loader bucket equipment of an excavator, and method of manufacturing the same
Die Erfindung betrifft ein geschweißtes Profil für Tieflöffel- und Ladeschaufelausrüstungen eines Baggers, wie Ausleger und Stiele, beinhaltend Ober- und Untergurte sowie damit in Wirkverbindung stehende Seitenwände.The invention relates to a welded profile for backhoe and loader bucket equipment of an excavator, such as booms and sticks, including upper and lower chords and side walls that are operatively connected to them.
Der US-A 4,034,876 ist eine Auslegerkonstruktion für einen Hydraulikbagger und ein Verfahren zur Herstellung des Auslegers zu entnehmen. Der Ausleger beinhaltet eine gekrümmte Außenkontur und weist Ober- und Untergurt sowie jeweils zwei dazwischen vorgesehene Seitenwände auf. Die Wandbereiche sind hierbei unter Bildung von Querschnittsverjüngungen, sowohl auf dem Ober- als auch auf dem Untergurt vorgesehen, wobei im Innenbereich weitere verstärkende Stützelemente angeordnet sind. Zur Aufnahme der Zylinderaufnahmepunkte werden im Bereich des Obergurtes separate Lagerbereiche aufgeschweißt. Durch diese Art der Schweißverbindung werden in hochbeanspruchten lokalen Bereichen unerwünschte Spannungen erzeugt.US-A 4,034,876 shows a boom construction for a hydraulic excavator and a method for manufacturing the boom. The boom has a curved outer contour and has an upper and lower flange and two side walls between them. The wall areas are provided with the formation of cross-sectional tapering, both on the upper and on the lower flange, with further reinforcing support elements being arranged in the inner region. Separate bearing areas are welded in the area of the top chord to accommodate the cylinder mounting points. This type of welded connection creates undesirable stresses in highly stressed local areas.
Eine ähnliche Konstruktion ist der JP-A 11 021 939 zu entnehmen, wobei zwischen den mit verdickten Endbereichen versehenen Ober- und Untergurten vom Querschnitt her geringer dimensionierte Seitenwände eingebracht werden.A similar construction can be found in JP-A 11 021 939, in which cross-sectionally smaller side walls are introduced between the upper and lower belts provided with thickened end regions.
Ein weiteres Querschnittsprofil eines Bagger-Auslegers ist der JP-A 200 102 0311 zu entnehmen. Zwischen einzelnen Eckbereichen werden Ober- und Untergurte sowie Seitenwände eingeschweißt.Another cross-sectional profile of an excavator boom can be found in JP-A 200 102 0311. Upper and lower chords and side walls are welded in between the individual corner areas.
In der DE-A 198 82 547 wird der Ausleger eines Löffelbaggers und ein Herstellungsverfahren für diesen abgehandelt. Der Ausleger beinhaltet eine Bumerangform, wobei das Trägerende des Auslegers an einem Fahrzeugaufbau montiert ist und ein Arm am Vorderende des Auslegers vorgesehen ist. Der Auslegerkörper ist hohl ausgebildet und weist einen dreieckigen Querschnitt auf. Der Erfindung liegt die Aufgabe zugrunde, ein im gattungsbildenden Teil des ersten Patentanspruches beschriebenes geschweißtes Profil für Tieflöffel- und Ladeschaufelausrüstungen dahingehend weiterzubilden, dass eine Reduzierung von Spannungen in hochbeanspruchten lokalen Bereichen herbeigeführt wird. Durch den Aufbau des Profils sollen die Schweißnähte in Bereiche niedrigerer Spannungen verlagert werden, so daß die Kerbwirkung der Schweißnähte eine geringere Bedeutung erhält, was letztendlich zu einer Erhöhung der Lebensdauer der Bauteile an sich führt.DE-A 198 82 547 deals with the boom of a backhoe and a manufacturing process for it. The boom includes a boomerang shape with the boom end of the boom mounted on a vehicle body and an arm provided at the front end of the boom. The boom body is hollow and has a triangular cross section. The invention has for its object to develop a welded profile described in the generic part of the first claim for backhoe and loader bucket equipment in such a way that a reduction of stresses is brought about in highly stressed local areas. The structure of the profile is intended to shift the weld seams to areas of lower stress, so that the notch effect of the weld seams is less important, which ultimately leads to an increase in the life of the components themselves.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Seitenwände mit oberen und unteren profilverstärkten Endbereichen versehen sind, die Eckbereiche für die zwischen den Endbereichen angeordneten Ober- und Untergurte bilden.This object is achieved according to the invention in that the side walls are provided with upper and lower profile-reinforced end regions which form corner regions for the upper and lower belts arranged between the end regions.
Vorteilhafte Weiterbildung des Erfindungsgegenstandes sind den gegenständlichen Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the invention can be found in the subject subclaims.
Bei einem Verfahren zur Herstellung eines geschweißten Profils für Tieflöffel- und Ladeschaufelausrüstungen eines Baggers, wie Ausleger und Stiele, bei welchem Unter- und Obergurte schweißtechnisch mit Seitenwandbereichen verbunden werden, wird erfindungsgemäß vorgeschlagen, dass die Seitenwände mit oberen und unteren profilverstärkten Endbereichen, insbesondere durch Schweißen verbunden werden, dass der Untergurt zwischen die zugehörigen Endbereiche gelegt und damit schweißtechnisch verbunden wird, und dass der Obergurt zwischen die zugehörigen Endbereiche gelegt und schweißtechnisch damit verbunden wird.In a method for producing a welded profile for backhoe and loader bucket equipment of an excavator, such as booms and sticks, in which lower and upper chords are connected to side wall areas by welding, the invention proposes that the side walls have upper and lower profile-reinforced end areas, in particular by welding be connected that the lower flange is placed between the associated end regions and is therefore connected by welding, and that the upper flange is placed between the associated end regions and is connected to it by welding technology.
Durch den Aufbau des erfindungsgemäßen Profils werden die Schweißnähte in Bereiche niedrigerer Spannungen verlagert, so dass die Kerbwirkung der Schweißnähte wesentlich reduziert werden kann. Durch diese Maßnahme kann eine Erhöhung der Lebensdauer der Bauteile, insbesondere der Ausleger- und Stiele von Baggern, insbesondere Hydraulikbaggern, herbeigeführt werden. Besonders interessant ist die Anwendung des Erfindungsgegenstandes bei Hydraulik-Großbaggern, wie sie u.a. in Minenbetrieben zum Einsatz gelangen. Derartige Geräte werden in schwierigstem Terrain eingesetzt, wobei sich Materialermüdungen in kostenintensiver Weise bemerkbar machen, da der Bagger bei auftretenden Schäden über einen längeren Zeitraum ausfällt.Due to the structure of the profile according to the invention, the weld seams are shifted to areas of lower stress, so that the notch effect of the weld seams can be significantly reduced. This measure can increase the lifespan of the components, in particular the boom and arm of excavators, in particular hydraulic excavators. The application of the subject matter of the invention is particularly interesting Large hydraulic excavators, such as those used in mine operations. Such devices are used in the most difficult terrain, with material fatigue being noticeable in a cost-intensive manner, since the excavator fails over a longer period of time if damage occurs.
Abweichend zum Stand der Technik werden die Ober- und Untergurte des vorgeschlagenen Profils zwischen die Seitenwände, insbesondere die damit verbundenen profil verdickten Endbereiche gelegt und schweißtechnisch damit verbunden.In a departure from the prior art, the upper and lower chords of the proposed profile are placed between the side walls, in particular the associated thickened end regions, and are connected thereto by welding.
Die jeweiligen vom Materialquerschnitt verstärkten Endbereiche werden analog zu den Seitenwänden - der jeweiligen Kontur des Auslegers und Stieles entsprechend - ausgebildet und schweißtechnisch miteinander verbunden.The respective end areas reinforced by the material cross section are formed analogously to the side walls - corresponding to the respective contour of the boom and stick - and are welded together.
Ein weiterer Vorteil des vorgeschlagenen Profils besteht darin, dass durch Integration der Aufnahmepunkte für die Zylinder- und die Hydraulikanlage in die obergurtseitigen profilverstärkten Endbereiche alle heute an diesen Stellen noch vorhandenen Schweißnähte entfallen können.Another advantage of the proposed profile is that by integrating the mounting points for the cylinder and hydraulic system in the upper-belt-side profile-reinforced end areas, all weld seams still present at these points can be omitted.
Aus fertigungstechnischer Sicht wird ein vereinfachter Aufbau der Bauteile ohne Montagevorrichtungen ermöglicht.From a manufacturing point of view, a simplified construction of the components without assembly devices is made possible.

In this example, the hydraulic excavator 1 has a backhoe equipment 5, including a boom 6 and a stick 7, and a bucket 8. Via a hydraulic cylinder 9 the boom 6 on the superstructure 2 is shifted. A further hydraulic cylinder 10 extends between a receiving profile 11, which is connected to the boom 6 by welding technology, and one arm end 12. A further hydraulic cylinder 13 extends between a bearing point 14 on the arm side and a bearing region 15 on the blade side, which is designed in the form of a lever arm frame.
Figur 2 zeigt als Prinzipsskizze einen mit einer Ladeschaufelausrüstung 5' versehenen Hydraulikbagger 1 '. Die wesentlichen Bauteile derFIG. 2 shows a basic sketch of a hydraulic excavator 1 'provided with loading shovel equipment 5'. The main components of the

Figur 3 zeigt den in Figur 1 prinzipiell dargestellten Ausleger 6, beinhaltend die erfindungsgemäßen Merkmale. Der Ausleger 6, weist einen Untergurt 16, einen Obergurt 17, Seitenwände 18 sowie profilverstärkte obere und untere Endbereiche 19, 20 auf. In den folgenden Figuren näher dargestellt ist, dass die parallel zueinander verlaufenden Seitenwände 18 mit oberen und unteren profilverstärkten Endbereichen 19,20 schweißtechnisch verbunden sind, die die Eckbereiche für die zwischen den Endbereichen 19,20 angeordneten Ober- 17 und Untergurte 16 bilden. Das in Figur 1 dargestellte separate Profil 11 wird erfindungsgemäß mit den obergurtseitig vorgesehenen profilverstärkten Endbereichen 19 konturmäßig ausgebildet, so dass in Folge der Integration der Aufnahmepunkte 21 für die in Figur 1 dargestellten Zylinder 10 (hier nicht dargestellt) alle bisher an diesen Stellen vorhandenen Schweißnähte entfallen. Das Fußpunktlager 22 wird entsprechend dem im Verbindungsbereich 23 gegebenen Querschnitt des Auslegers 6 bzw. 6' geformt und mit diesem durch Schweißen verbunden. Gleiches gilt für den gabelförmig ausgebildeten Aufnahmebereich 24 für den hier nicht weiter dargestellten Stiel 7 gem. Figur 1. Der in den Seitenwänden 18 vorgesehene Lagerbereich 21 ' dient zur Aufnahme des in Figur 1 dargestellten einen Endes des Hydraulikzylinders 9.Figure 3 shows the boom 6 shown in principle in Figure 1, including the features of the invention. The boom 6 has a lower flange 16, an upper flange 17, side walls 18 and profile-reinforced upper and lower end regions 19, 20. In the following figures it is shown in more detail that the parallel side walls 18 are welded to upper and lower profile-reinforced end regions 19, 20 which form the corner regions for the upper 17 and lower chords 16 arranged between the end regions 19, 20. The separate profile 11 shown in FIG. 1 is contoured according to the invention with the profile-reinforced end regions 19 provided on the upper chord side, so that as a result of the integration of the mounting points 21 for the cylinders 10 shown in FIG , The base bearing 22 is in accordance with the cross section given in the connection area 23 Boom 6 or 6 'shaped and connected to this by welding. The same applies to the fork-shaped receiving area 24 for the stem 7 according to FIG. 1. The bearing area 21 ′ provided in the side walls 18 serves to accommodate the one end of the hydraulic cylinder 9 shown in FIG. 1.
Die Figuren 4 bis 8 zeigen unterschiedliche Querschnitte von Auslegern 6, wie sie beispielsweise in Figur 3 dargestellt sind. Folgende Bauteile sind erkennbar: Der Untergurt 16, der Obergurt 17, die Seitenwände 18, der profilverstärkte untere Endbereich 20 sowie die in die oberen verstärkten Endbereiche 19 integrierten Lagerbereiche 21. Die Seitenwände 18 werden mit den vom Querschnitt her dickeren profilverstärkten Endbereichen 19,20 im Bereich der Verbindungsstellen 25,26 schweißtechnisch miteinander verbunden.Figures 4 to 8 show different cross sections of arms 6, as shown for example in Figure 3. The following components can be seen: the lower flange 16, the upper flange 17, the side walls 18, the profile-reinforced lower end region 20 and the bearing regions 21 integrated into the upper reinforced end regions 19. The side walls 18 are formed with the profile-reinforced end regions 19, 20 in cross section The area of the connection points 25, 26 is welded together.
Unterschiede zwischen den Figuren 4 bis 8 sind darin zu sehen, dass die profilverstärkten Endbereiche mit querschnittsreduzierenden Bereichen 27,28 außenbündig, innenbündig oder zentriert versehen sind, wodurch zum einen ein Profil mit einer glatten Innenkontur 29 (Figur 5), zum anderen ein Profil mit einer glatten Außenkontur 30 (Figur 4) sowie ein Profil mit mittig zu den profilverstärkten Endbereichen 19,20 angebrachten Seitenwänden 18 (Figur 6) in Kastenform gebildet wird. Der Fachmann wird die geeignete Kontur dem jeweiligen Anwendungsfall anpassen. Der Untergurt 16 schließt in allen Fällen bündig mit dem zugehörigen Endbereich 20 ab. Der Obergurt 17 ist zwischen die jeweiligen Endbereiche 19 gelegt und wird analog zum Untergurt schweißtechnisch mit selbigen verbunden.Differences between FIGS. 4 to 8 can be seen in the fact that the profile-reinforced end regions are provided with cross-section-reducing regions 27, 28 that are flush with the inside, flush with the center, or centered, which means that a profile with a smooth inner contour 29 (FIG. 5) and a profile with it a smooth outer contour 30 (FIG. 4) and a profile with side walls 18 (FIG. 6) attached centrally to the profile-reinforced end regions 19, 20 are formed in a box shape. The person skilled in the art will adapt the suitable contour to the respective application. The lower flange 16 is flush with the associated end region 20 in all cases. The upper flange 17 is placed between the respective end regions 19 and is welded to the lower flange analogously to the lower flange.
Gemäß Figur 7 sind alternativ ausgebildete querschnittsreduzierende Bereiche 27, 28 dargestellt. Die Aufnahmepunkte 21 für die in Figur 1 dargestellten Zylinder 10 (hier nicht erkennbar) sind in die Profile 11 integriert, während sie bei den anderen Figuren über die Außenkonturen hervorstehen. Es wird eine im wesentlichen polygonale Innenkontur 31 erzeugt, wobei glatte Außenkonturen 30 gebildet werden. Figur 8 zeigt eine Kombination querschnittsreduzierender Bereiche 27, 28, wie sie den Figuren 4 und 6 zu entnehmen ist.According to FIG. 7, alternative cross-sectional areas 27, 28 are shown. The mounting points 21 for the cylinders 10 shown in FIG. 1 (not recognizable here) are integrated in the profiles 11, while in the other figures they protrude beyond the outer contours. An essentially polygonal inner contour 31 is produced, smooth outer contours 30 being formed. FIG. 8 shows a combination of cross-section-reducing regions 27, 28, as can be seen in FIGS. 4 and 6.
In allen Fällen erfolgen die Anbindungen von Ober- 17 und Untergurt 16 im Bereich der dickeren Profilquerschnitte der Endbereiche 19,20. Durch den Aufbau des Profils werden die Schweißnähte in Bereiche niedrigerer Spannungen verlagert, wobei die Kerbwirkung der Schweißnähte reduziert wird, was zu einer nicht unbeträchtlichen Erhöhung der Lebensdauer der Bauteile führt.In all cases, the upper and lower chords 16 are connected in the region of the thicker profile cross sections of the end regions 19, 20. Due to the structure of the profile, the weld seams are shifted to areas with lower stresses, whereby the notch effect of the weld seams is reduced, which leads to a not inconsiderable increase in the service life of the components.
Alternativ besteht auch die Möglichkeit die untergurtseitigen Endbereiche 20 von ihrer Kontur her so auszubilden, daß sie integrierte Aufnahmebereiche für Zylinderaufnahmepunkte bilden. Dies wäre die in den Figuren 4 bis 8 dargestellte um 180° gedrehte Version. Auch hier wird der Fachmann die entsprechend notwendige konstruktive Ausgestaltung dem jeweiligen Baggertyp anpassen. As an alternative, there is also the possibility of designing the end regions 20 on the lower flange side in such a way that they form integrated receiving regions for cylinder receiving points. This would be the version shown in FIGS. 4 to 8 rotated by 180 °. Here, too, the person skilled in the art will adapt the corresponding structural design to the particular excavator type.
