Description

Die vorliegende Erfindung betrifft eine Ballastvorrichtung, insbesondere eine Ballastvorrichtung eines Bau- und/oder Umschlaggeräts, mit einem abnehmbaren Ballastelement.The present invention relates to a ballast device, in particular a ballast device of a construction and / or handling device, with a removable ballast element.

Ballastelemente kommen bei einer Vielzahl von Bau- und/oder Umschlaggeräten als Gegengewicht z. B. für das Arbeitsgerät zum Einsatz und sind üblicherweise abnehmbar, um das Transportgewicht und die Transportabmessungen zu verringern. Oftmals stellt das Ballastelement dabei einen Grundballast dar, welcher für den Transport demontiert und am Einsatzort wieder montiert wird. Insbesondere können solche Ballastvorrichtungen bei verfahrbaren Kränen, insbesondere Raupenkränen zum Einsatz kommen, welche z.B. mit einem Mäkler als Bohrgerät verwendet werden können. Die Montage und Demontage des Ballastelements geschieht dabei entweder mit Hilfe eines zusätzlichen Krans oder durch eine entsprechende Beseilung mit der eigenen Mäklerkinematik.Ballast elements come in a variety of construction and / or handling equipment as a counterweight z. B. for the implement used and are usually removable to reduce the transport weight and the transport dimensions. Often, the ballast element is a basic ballast, which is dismantled for transport and mounted again at the site. In particular, such ballast devices can be used in traveling cranes, especially crawler cranes, which are e.g. can be used with a leader as a drill. The assembly and disassembly of the ballast element happens either with the help of an additional crane or by a corresponding Beseilung with the own Mäklerkinematik.

Nach dem Aufsetzen des Grundballasts z. B. auf eine Ballastplattform wird das Ballastelement üblicherweise mit dieser verschraubt, wofür es einer genauen Positionierung bedarf. Bei bekannten Ballastvorrichtungen wurde die Positionierung üblicherweise durch an der Auflage des Ballastelements angebrachte Führungsbolzen bzw. Führungsbohrungen unterstützt. Diese stellen jedoch lediglich eine gewisse Hilfe bei der Feinpositionierung dar, während der gesamte Positioniervorgang weiterhin massiv vom Können des Fahrers und der Genauigkeit der Steuerung des Hilfsgeräts abhängig ist.After placing the base ballast z. B. on a ballast platform, the ballast element is usually bolted to this, for which there is a precise positioning requirement. In known ballast devices, the positioning has usually been supported by mounted on the support of the ballast guide pins or guide holes. However, these only provide some help with fine positioning, while the entire positioning process continues to be heavily dependent on the skill of the driver and the accuracy of the control of the auxiliary device.

Eine solche Ballastvorrichtung ist in Dokument JP 2002 070 076 A offenbart.Such a ballast device is in document JP 2002 070 076 A disclosed.

Aufgabe der vorliegenden Erfindung ist es daher, eine Ballastvorrichtung zur Verfügung zu stellen, bei welcher das Positionieren des Ballastelements vereinfacht ist.Object of the present invention is therefore to provide a ballast device available, in which the positioning of the ballast element is simplified.

Erfindungsgemäß wird diese Aufgabe von einer Ballastvorrichtung gemäß Anspruch 1 gelöst. Eine solche Ballastvorrichtung insbesondere eines Bau- und/oder Umschlaggeräts umfasst dabei ein Ballastelement, welches mindestens ein an seiner Oberseite angebrachtes Positionierungselement aufweist, welches seitlich über das Ballastelement hinausragt.According to the invention this object is achieved by a ballast device according to claim 1. Such a ballast device, in particular of a construction and / or handling device, comprises a ballast element which has at least one positioning element mounted on its upper side, which protrudes laterally beyond the ballast element.

Der Vorteil eines solchen oben am Ballastelement angeordneten Positionierungselements ist dabei, dass es bei der Montage erheblich besser einsichtig ist als die bekannten unter dem Ballast befindlichen Führungen. Durch das seitliche über das Ballastelement hinausragen des Positionierungselements kann dieses mit einem daneben liegenden Körper zusammenwirken und so die Positionierung erleichtern. Eine solche Positionierung des Ballastelements an der Oberseite hat zusätzlich den Vorteil, dass ein Umkippen des Ballastelements vor dem darauffolgenden Festschrauben verhindert wird und sich ein zusätzlicher Halt während des Betriebs ergibt.The advantage of such a top of the ballast element arranged positioning element is that it is much easier to understand during assembly than the known located under the ballast guides. By protruding laterally beyond the ballast element of the positioning element, this can interact with an adjacent body and thus facilitate the positioning. Such a positioning of the ballast element at the top has the additional advantage that tilting of the ballast element is prevented before the subsequent tightening and results in an additional grip during operation.

Vorteilhafterweise weist das Positionierungselement dabei ein Führungselement auf, welches mit einem Gegenführungselement zusammenwirkt, welches an der Oberseite eines ersten Körpers, neben dem das Ballastelement in montierter Stellung angeordnet ist, angebracht ist. Führungselement und Gegenführungselement sorgen so für eine genaue Positionierung des Ballastelements, wobei die Positionierung insbesondere dadurch vereinfacht ist, dass beide Elemente gut einsichtig auf der Oberseite von Ballastelement und erstem Körper angeordnet sind. Zusätzlich ermöglicht das Zusammenwirken von Führungselement und Gegenführungselement auch die bereits oben erwähnte Kippsicherung sowie den zusätzlichen Halt während des Betriebes.Advantageously, the positioning element in this case has a guide element which cooperates with a counter-guide element which is attached to the upper side of a first body, next to which the ballast element is arranged in the mounted position. Guide element and counter-guide element thus ensure accurate positioning of the ballast element, wherein the positioning is particularly simplified in that both elements well understand are arranged on the top of ballast element and first body. In addition, the interaction of guide element and counter-guide element also allows the already mentioned above anti-tip device and the additional support during operation.

Weiterhin vorteilhafterweise weist das Positionierungselement einen teilweise entlang der Oberseite des Ballastelements verlaufenden Arm auf, an dessen freiem Ende ein Führungselement angeordnet ist. Hierdurch ist eine stabile Verbindung zwischen Positionierungselement und Ballastelement möglich, wobei die Anordnung des Arms an der Oberseite des Ballastelements den zusätzlichen Vorteil hat, dass die Kupplungsfläche des Ballastelements, mit welcher dieses z. B. an dem ersten Körper seitlich anliegt, nicht verändert werden braucht.Further advantageously, the positioning element has a part extending along the upper side of the ballast element arm, at the free end of a guide element is arranged. As a result, a stable connection between the positioning element and ballast element is possible, wherein the arrangement of the arm at the top of the ballast element has the additional advantage that the coupling surface of the ballast element, with which this z. B. on the first body laterally, does not need to be changed.

Weiterhin vorteilhafterweise umfasst die Anordnung aus Führungselement und Gegenführungselement einen Bolzen und eine Buchse, welche in vertikaler Richtung ineinander geführt werden können. Dies ermöglicht eine einfache und effektive Positionierungshilfe, welche zusätzlich als eine stabile Verbindung zusätzlichen Halt gibt und eine Kippsicherung darstellt.Further advantageously, the arrangement of guide element and counter-guide element comprises a bolt and a bush, which can be guided into one another in the vertical direction. This allows a simple and effective positioning aid, which additionally gives as a stable connection additional support and represents a tilt protection.

Weiterhin vorteilhafterweise umfasst das Führungselement des Positionierungselements eine durchgehende Buchse. Diese Anordnung mit einer durchgehenden Buchse am Führungselement des Positionierungselements des Ballastelements hat den Vorteil, dass hierdurch einer Verschmutzung der Führung vorgebeugt bzw. ein Reinigen des Positionierungselements erleichtert wird. Hierbei kann festgesetzter Dreck in der Führung leicht durchgestoßen werden, im Gegensatz zu einer als Gegenführungselement wirkenden Buchse, welche nicht durchgehend ausgeführt werden könnte.Further advantageously, the guide element of the positioning element comprises a continuous socket. This arrangement with a continuous bushing on the guide element of the positioning element of the ballast element has the advantage that thereby contamination of the guide is prevented or a cleaning of the positioning element is facilitated. In this case, set dirt in the guide can be easily pushed through, in contrast to acting as a counter-guide sleeve, which could not be carried out continuously.

Weiterhin vorteilhafterweise weist das Gegenführungselement einen angefasten Bolzen auf. Insbesondere kann es so erfindungsgemäß mit einer Buchse am Führungselement des Positionierungselementes zusammenwirken, was die bereits oben beschriebenen Vorteile hat. Zudem erlaubt die Fase am Bolzen eine einfachere Zentrierung und damit eine erleichterte Montage.Further advantageously, the counter-guide element has a chamfered pin. In particular, it can cooperate according to the invention with a bushing on the guide element of the positioning element, which is already the case above has described benefits. In addition, the chamfer on the bolt allows easier centering and thus easier assembly.

Weiterhin vorteilhafterweise ist erfindungsgemäß eine Ballastplattform vorgesehen, auf der das Ballastelement mit seiner Unterseite aufgesetzt wird. Hierdurch ist eine stabile Verbindung zwischen Ballastelement und Bau- und/oder Umschlaggerät möglich. Hierbei können an der Unterseite des Ballastelements weiterhin Führungselemente wie z. B. Führungsbolzen und entsprechende Führungsbohrungen angeordnet sein, welche zusätzlich zum erfindungsgemäß an der Oberseite des Ballastelements angeordneten Positionierungselement eine vereinfachte Zentrierung des Ballastelements erlauben. Insbesondere erleichtert dabei das erfindungsgemäße Positionierungselement eine Vorpositionierung, die unten am Ballastelement angeordneten Führungen eine Feinpositionierung.Further advantageously, a ballast platform according to the invention is provided, on which the ballast element is placed with its underside. As a result, a stable connection between the ballast element and construction and / or handling equipment is possible. In this case, on the underside of the ballast element further guide elements such. B. guide bolts and corresponding guide holes may be arranged, which allow in addition to the present invention arranged at the top of the ballast element positioning a simplified centering of the ballast element. In particular, the positioning element according to the invention facilitates a pre-positioning, the guides arranged at the bottom of the ballast element make a fine positioning.

Weiterhin vorteilhafterweise wird das Ballastelement in montierter Stellung an der Ballastplattform befestigt, insbesondere verschraubt. Dies ermöglicht eine sichere Verbindung für den Betrieb des Gerätes.Further advantageously, the ballast element is mounted in the mounted position on the ballast platform, in particular screwed. This allows a secure connection for the operation of the device.

Alternativ oder zusätzlich kann das Ballastelement auch in montierter Stellung durch eine horizontal verlaufende Befestigung, insbesondere eine horizontale Verschraubung, befestigt werden. Dies erlaubt eine ebenso sichere Montage wie eine vertikale Verschraubung durch die Ballastplattform.Alternatively or additionally, the ballast element in the mounted position by a horizontally extending attachment, in particular a horizontal screw, are attached. This allows a secure mounting as well as a vertical screwing through the ballast platform.

Weiterhin vorteilhafterweise ist erfindungsgemäß am Positionierungselement ein Anschlagpunkt zum Heben des Ballastelements angebracht. So kann das Positionierungselement eine Doppelfunktion ausfüllen, indem es einerseits das Positionieren erleichtert und andererseits erfindungsgemäß den Anschlagpunkt zum Heben des Ballastelements aufweist. Dies ist möglich, da das Positionierungselement ohnehin an der Oberseite des Ballastelements angebracht ist, so dass auf einen zusätzlichen Anschlagpunkt verzichtet werden kann. Insbesondere wenn das Positionierungselement einen teilweise entlang der Oberseite des Ballastelements verlaufenden Arm aufweist, kann der Anschlagpunkt durch eine entsprechende Bohrung in diesem Arm zur Verfügung gestellt werden.Further advantageously, according to the invention, an attachment point for lifting the ballast element is attached to the positioning element. Thus, the positioning element can perform a dual function in that on the one hand facilitates positioning and on the other hand according to the invention has the attachment point for lifting the ballast element. This is possible because the positioning element is attached to the top of the ballast element anyway, so that can be dispensed with an additional attachment point. In particular, when the positioning element extending partially along the top of the ballast element Arm, the anchor point can be provided by a corresponding hole in this arm.

Weiterhin vorteilhafterweise ist bei der erfindungsgemäßen Ballastvorrichtung ein in montierter Stellung des Ballastelements neben diesem liegender erster Körper ein weiteres Ballastelement. Werden also erfindungsgemäß mehrere Ballastelemente verwendet, können diese über das erfindungsgemäße Positionierungselement aneinander positioniert werden. Insbesondere weist der in montierter Stellung des Ballastelements neben diesem liegende erste Körper dabei die Gegenführungselemente für die am Positionierungselement des Ballastelements angeordneten Führungselemente auf. Insbesondere handelt es sich zudem bei dem weiteren Ballastelement um einen Zusatzballast, welcher für den Transport des Bau- und/oder Umschlaggeräts üblicherweise nicht demontiert wird, während das erfindungsgemäße Ballastelement mit dem erfindungsgemäßen Positionierungselement einen Grundballast darstellt, welcher für den Transport demontiert wird.Further advantageously, in the ballast device according to the invention in a mounted position of the ballast element next to this lying first body another ballast element. Thus, if more ballast elements are used according to the invention, they can be positioned against one another via the positioning element according to the invention. In particular, in the mounted position of the ballast element adjacent to this first body has the counter-guide elements for the arranged on the positioning of the ballast element guide elements. In particular, it is also in the other ballast element to an additional ballast, which is usually not dismantled for the transport of the construction and / or handling equipment, while the ballast according to the invention with the positioning element according to the invention represents a base ballast, which is dismantled for transport.

Weiterhin vorteilhafterweise weist das weitere Ballastelement auf seiner Oberseite einen Anschlagpunkt zum Anheben auf. Über diesen Anschlagpunkt kann das weitere Ballastelement ebenfalls montiert bzw. demontiert werden. Wird das weitere Ballastelement für den Transport des Bau- und/oder Umschlaggeräts üblicherweise demontiert, weist es erfindungsgemäß vorteilhafterweise ebenfalls ein erfindungsgemäßes Positionierungselement auf, welches dann z. B. mit Gegenführungselementen am Oberwagen des Bau- und/oder Umschlaggeräts zusammenwirkt. Wird das weitere Ballastelement jedoch üblicherweise zum Transport nicht demontiert, kann auf diese Positionierungselemente verzichtet werden.Further advantageously, the further ballast element has on its upper side an attachment point for lifting. About this attachment point, the other ballast element can also be mounted or dismounted. If the other ballast element for the transport of construction and / or handling equipment usually dismantled, it advantageously according to the invention also has an inventive positioning element, which then z. B. cooperates with counter-guide elements on the superstructure of the construction and / or handling equipment. However, if the further ballast element is not usually disassembled for transport, this positioning element can be dispensed with.

Weiterhin vorteilhafterweise ist ein in montierter Stellung des Ballastelements neben diesem liegender erster Körper mit dem Oberwagen des Bau- und/oder Umschlaggeräts verbunden. So kann das erfindungsgemäße Ballastelement am Einsatzort des Bau- und/oder Umschlaggeräts einfach und sicher montiert werden und dient als Gegengewicht am Oberwagen. Wird ein Zusatzballast verwendet, welcher mit dem Oberwagen verbunden bleibt, sind üblicherweise an diesem die Gegenführungselemente angeordnet. Andernfalls können die Gegenführungselemente auch direkt am Oberwagen des Bau- und/oder Umschlaggerätes angeordnet sein.Further advantageously, a mounted in the next position of the ballast element next to this first body is connected to the superstructure of the construction and / or handling equipment. Thus, the ballast element according to the invention at the site of the construction and / or handling equipment can be easily and safely mounted and serves as a counterweight on the superstructure. If an additional ballast is used, which remains connected to the superstructure, the counter-guide elements are usually at this arranged. Otherwise, the counter-guide elements can also be arranged directly on the superstructure of the construction and / or handling equipment.

Weiterhin vorteilhafterweise weist das erfindungsgemäße Ballastelement mindestens zwei auf einer Seite seitlich über seine Oberseite hinausragende Positionierungselemente auf. Durch diese zwei auf einer Seite seitlich über seine Oberseite hinausragenden Positionierungselemente ist die erfindungsgemäß vereinfachte Montage möglich, wobei die zwei Elemente für eine besonders stabile und sichere Verbindung sorgen, insbesondere als Kippschutz und als zusätzlicher Halt während des Betriebes.Furthermore advantageously, the ballast element according to the invention has at least two positioning elements projecting laterally beyond its upper side on one side. By means of these two positioning elements projecting laterally beyond its upper side on one side, the assembly simplified according to the invention is possible, the two elements providing a particularly stable and secure connection, in particular as anti-tilting and as additional support during operation.

Weiterhin vorteilhafterweise ist das erfindungsgemäße Ballastelement der zum Transport abnehmbare Grundballast des Bau- und/oder Umschlaggeräts. Durch das erfindungsgemäße Positionierungselement kann dieser dann einfach montiert werden.Further advantageously, the ballast element according to the invention is the removable for transport base ballast of the construction and / or handling equipment. By the positioning element according to the invention, this can then be easily mounted.

Weiterhin vorteilhafterweise ist das Führungselement und/oder das Gegenführungselement rund oder eckig ausgeführt. Beide Möglichkeiten ergeben eine einfache und sichere Positionierung und Verbindung.Further advantageously, the guide element and / or the counter-guide element is round or square. Both options result in a simple and secure positioning and connection.

Die vorliegende Erfindung umfasst weiterhin ein Bau- und/oder Umschlaggerät, insbesondere einen Raupenkran, mit einer Ballastvorrichtung, wie sie oben beschrieben wurde. Offensichtlich ergeben sich hierbei die gleichen Vorteile wie für die Ballastvorrichtung selbst. Insbesondere kann die Ballastvorrichtung dabei vorteilhafterweise bei einem Bohrgerät, insbesondere einem Raupenkran mit Mäkler, zum Einsatz kommen.The present invention further comprises a construction and / or handling device, in particular a crawler crane, with a ballast device, as described above.

Figuren 1 und 2 zeigen ein Ausführungsbeispiel des erfindungsgemäßen Bau- und/oder Umschlaggeräts mit einem Ausführungsbeispiel der erfindungsgemäßen Ballastvorrichtung 1. Bei dem Gerät handelt es sich dabei um einen Raupenkran, welcher als verfahrbares Bohrgerät eingesetzt wird. Das Gerät umfasst ein Grundgerät aus Unterwagen 3 mit Kettenantrieben, einem drehbar auf dem Unterwagen 3 angeordneten Oberwagen 2 sowie der am Oberwagen 2 hinten angeordneten Ballastvorrichtung 1. Vorne am Oberwagen 2 ist das Arbeitsgerät angeordnet, in diesem Fall der Mäkler 4. FIGS. 1 and 2 show an embodiment of the construction and / or handling device according to the invention with an embodiment of the ballast device according to the invention 1. The device is a crawler crane, which is used as a movable drill. The device comprises a base unit comprising undercarriage 3 with chain drives, a superstructure 2 rotatably mounted on the undercarriage 3, and the ballast device 1 arranged at the rear of the superstructure 2. The work equipment is arranged in front of the superstructure 2, in this case the broker 4.

Die Ballastvorrichtung 1 umfasst dabei den Grundballast 20, welcher zur Verringerung des Transportgewichts und der Transportabmessungen für den Transport demontiert und am Einsatzort wieder montiert wird. Die Montage und Demontage geschieht dabei entweder mit Hilfe eines zusätzlichen Krans oder durch eine entsprechende Beseilung mit der eigenen Mäklerkinematik des Mäklers 4.The ballast device 1 comprises the base ballast 20, which is dismantled to reduce the transport weight and the transport dimensions for transport and mounted again at the site. The assembly and disassembly happens either with the help of an additional crane or by a corresponding Beseilung with the own Mäklerkinematik the Mäklers. 4

Figur 3a zeigt nun in einer Schnittansicht die erfindungsgemäß vereinfachte Positionierung des Ballastelements 20 am Oberwagen. Dabei ist der Stahlbau 5 des Oberwagens 2 zu sehen, welcher in seinem vorderen Teil Anlenkpunkte 6 für den Ausleger, in diesem Fall für den Mäkler 4, aufweist, sowie in einem hinteren Bereich Verbindungselemente zur Verbindung mit dem Ballastelement 20. Dabei ist am Stahlbau 5 des Oberwagens eine Ballastplattform 15 angeordnet, auf welcher das Ballastelement 20 aufgesetzt und verschraubt wird. Erfindungsgemäß weist das Ballastelement 20 nun ein an seiner Oberseite angebrachtes Positionierungselement 10 auf, welches die Positionierung des Ballastelements 20 bei der Montage erheblich vereinfacht. Das Ballastelement 20 mit den an seiner Oberseite angeordneten zwei Positionierungselementen 10 ist in Figur 3b noch einmal in einer Rückansicht zu sehen. FIG. 3a now shows in a sectional view of the present invention simplified positioning of the ballast element 20 on the superstructure. In this case, the steel structure 5 of the superstructure 2 can be seen, which has in its front part articulation points 6 for the boom, in this case for the leader 4, and in a rear area connecting elements for connection to the ballast element 20. It is on the steel structure the superstructure a ballast platform 15 is arranged, on which the ballast element 20 is placed and screwed. According to the invention, the ballast element 20 now has a positioning element 10 mounted on its upper side, which considerably simplifies the positioning of the ballast element 20 during assembly. The ballast element 20 with the arranged at its top two positioning elements 10 is in FIG. 3b to see again in a rear view.

Figur 4a zeigt die erfindungsgemäße Ballastvorrichtung noch einmal in einer vergrößerten Schnittansicht. Das Positionierungselement 10 weist dabei ein Führungselement 11 auf, welches mit einem Gegenführungselement 12 zusammenwirkt und der Positionierung des Ballastelements 20 am Oberwagen des Bau- und/oder Umschlaggeräts dient. Das Gegenführungselement 12 ist dabei an der Oberseite eines ersten Körpers 21 angeordnet, welcher sich in montierter Stellung des Ballastelements 20 neben dem Ballastelement befindet. Hierbei handelt es sich bei dem ersten Körper 21 um einen Zusatzballast, welcher beim Transport des Bau- und/oder Umschlaggeräts üblicherweise nicht demontiert wird und am Oberwagen verbleibt. FIG. 4a shows the ballast device according to the invention again in an enlarged sectional view. The positioning element 10 in this case has a guide element 11, which cooperates with a counter-guide element 12 and the positioning of the ballast element 20 on the superstructure of the construction and / or handling device is used. The counter-guide element 12 is arranged on the upper side of a first body 21, which is located in the assembled position of the ballast element 20 next to the ballast element. Here, the first body 21 is an additional ballast, which is usually not disassembled during transport of the construction and / or handling device and remains on the uppercarriage.

Das Positionierungselement 10 weist dabei einen teilweise entlang der Oberseite des Ballastelements 20 verlaufenden Arm 13 auf, an dessen freien Ende das Führungselement 11 angeordnet ist. Der Arm 13 ist dabei als ein Befestigungsblech ausgeführt. In dem Arm 13 ist eine Bohrung 14 vorgesehen, welche als ein Anschlagpunkt zum Heben des Ballastelements 20 verwendet werden kann, so dass hier kein weiteres Hilfsmittel notwendig ist. Der Anschlagpunkt 14 ist hierfür senkrecht über der Schwerpunktlinie des Ballastelements 20 angeordnet.The positioning element 10 in this case has a partially extending along the upper side of the ballast element 20 arm 13, at the free end of the guide member 11 is arranged. The arm 13 is designed as a mounting plate. In the arm 13, a bore 14 is provided, which can be used as a stop point for lifting the ballast element 20, so that No further aids are necessary here. The attachment point 14 is for this purpose arranged vertically above the center of gravity line of the ballast element 20.

Am Zusatzballast 21, welcher üblicher Weise nicht zum Transport demontiert wird und deshalb auch kein Positionierungselement aufweisen muss, sind dagegen die in Figur 3b zu sehenden Anschlagpunkte 24 zum Heben des Zusatzballastes 21 vorgesehen.At the additional ballast 21, which is usually not dismantled for transport and therefore must have no positioning element, however, are in FIG. 3b to be seen stop points 24 for lifting the additional ballast 21 is provided.

Das Führungselement 11 am Positionierungselement 10 sowie das Gegenführungselement 12 am Zusatzballast 21 bilden dabei eine Anordnung aus Bolzen und Buchse, welche in vertikaler Richtung ineinander geführt werden können und so das Positionieren des Ballastes 20 am Oberwagen erleichtern. Ein besonderer Vorteil dieser Anordnung von Führungselement und Gegenführungselement an der Oberseite der jeweiligen Ballastelemente ist dabei, dass die oben angebrachten Führungen besser einsichtig sind als die sich im Stand der Technik unter dem Ballast befindlichen Befestigungsbohrungen und -führungen. Gleichzeitig verhindern die oben angeordneten Führungen ein Umkippen des Grundballastes vor dem Festschrauben, bzw. geben ihm danach zusätzlichen Halt während des Betriebes.The guide element 11 on the positioning element 10 and the counter-guide element 12 on the additional ballast 21 thereby form an arrangement of bolt and bush, which can be guided into each other in the vertical direction and thus facilitate the positioning of the ballast 20 on the superstructure. A particular advantage of this arrangement of guide element and counter-guide element at the top of the respective ballast elements is that the guides mounted above are better understood than the fastening bores and guides located under the ballast in the prior art. At the same time prevent the above-arranged guides tipping the base ballast before tightening, or give him then additional support during operation.

Nach dem Aufsetzen des Ballastelements 20 auf der Ballastplattform 15 wird dieses über Befestigungsschrauben 16 an der Ballastplattform 15 festgeschraubt. Dabei sind zusätzlich zu den auf der Oberseite des Ballastelements 20 angeordneten Positionierungselementen 10 weitere Positionierungselemente 18 an der Unterseite des Ballastes angeordnet, welche die Zentrierung des Ballastelements 20 auf der Ballastplattform 15 vereinfachen. Auch das weitere Ballastelement 21 weist an seiner Unterseite wie im Stand der Technik Positionierungsvorrichtungen auf und ist mit der Ballastplattform 15 über Schrauben 17 verschraubt. Ebenso sind jedoch andere Auflagearten sowie eine durch eine horizontale Verschraubung erfolgende Befestigung möglich.After placing the ballast element 20 on the ballast platform 15, this is screwed by means of fastening screws 16 to the ballast platform 15. In addition to the positioning elements 10 arranged on the upper side of the ballast element 20, further positioning elements 18 are arranged on the underside of the ballast, which simplify the centering of the ballast element 20 on the ballast platform 15. The further ballast element 21 has on its underside as in the prior art positioning devices and is bolted to the ballast platform 15 via screws 17. However, other types of support as well as attachment by a horizontal screw connection are possible.

In Figur 4b ist eine bevorzugte Ausführungsform des erfindungsgemäßen Positionierungselements 10 des Ballastelements 20 gezeigt. Hierbei ist am Zusatzballast 21 auf dessen Oberseite ein angefaster Bolzen 12 vorgesehen, welcher in das am Positionierungselement 10 angeordnete Führungselement 11 eingreift. Das Führungselement 11 ist als durchgehende Buchse ausgeführt, wodurch einer Verschmutzung der Führung vorgebeugt bzw. ein Reinigen erleichtert wird. Im Gegensatz zu einer am Zusatzballast 21 angeordneten Buchse kann so festgesetzter Dreck in der Führung 11 leicht durchgestoßen werden.In FIG. 4b a preferred embodiment of the positioning element 10 according to the invention of the ballast element 20 is shown. Here is the additional ballast 21 on the upper side of a chamfered pin 12 is provided, which engages in the arranged on the positioning element 10 guide member 11. The guide member 11 is designed as a continuous socket, whereby contamination of the guide is prevented or cleaning is facilitated. In contrast to a arranged on the additional ballast 21 bush so festinetter dirt in the guide 11 can be easily pushed through.

Ebenso ist nochmals die Bohrung 14 im Befestigungsblech 13, welches als teilweise entlang der Oberseite des Ballastelements 20 verlaufender Arm 13 ausgeführt ist, gezeigt. Diese kann als Anschlagpunkt zum Heben des Ballastelements 20 verwendet werden, wodurch kein weiteres Hilfsmittel notwendig ist.Likewise, again the bore 14 in the mounting plate 13, which is designed as partially along the upper side of the ballast element 20 extending arm 13 is shown. This can be used as an attachment point for lifting the ballast element 20, whereby no further aid is necessary.
