Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Befestigung einer Abdichtbürste an einer Tunnelbohrmaschine, mit wenigstens zwei auf zwei gegenüberliegenden Seiten der Abdichtbürste angeordneten Befestigungselementen, mit denen eine Halteplatte der Abdichtbürste auf einem Grundelement gehalten ist. Des Weiteren betrifft die Erfindung eine Tunnelbohrmaschine mit einem Grundelement, auf dem mehrere Abdichtbürsten mittels einer solchen Vorrichtung befestigt sind.The invention relates to a device for fastening a sealing brush to a tunnel boring machine, with at least two fastening elements arranged on two opposite sides of the sealing brush, with which a retaining plate of the sealing brush is held on a base element. Furthermore, the invention relates to a tunnel boring machine with a base element on which a plurality of sealing brushes are fastened by means of such a device.
Eine gattungsgemäße Vorrichtung ist aus der
Eine entsprechende Tunnelbohrmaschine ist beispielsweise in der
Die in solchen, beispielsweise zur Herstellung von U-Bahn- oder Straßentunnels verwendeten Tunnelbohrmaschinen eingesetzten Abdichtbürsten dichten gegenüber dem Erdreich ab und halten Grundwasser zurück. Während des Bohrvorgangs wird in den Bereich der Abdichtbürsten eine zusätzliche Dichtmasse eingeleitet, wie beispielsweise ein geeignetes Abdichtfett. Die Abdichtbürsten sind aufgrund der Art ihres Einsatzes einem gewissen Verschleiß unterworfen und es ist mit zunehmendem Verschleiß der Abdichtbürsten erforderlich, eine größere Menge des Abdichtmittels in den Bereich der Abdichtbürsten einzuleiten, um eine ausreichende Abdichtung zu gewährleisten. Da die einzuleitende Menge des Abdichtmittels mit dem Verschleiß der Abdichtbürsten zunimmt, steigen die Betriebskosten beim Einsatz der Tunnelbohrmaschine stetig an, bis ein Punkt erreicht wird, an dem es kostengünstiger ist, die Abdichtbürsten auszutauschen als eine immer größer werdende Menge des Abdichtmittels einzuleiten.The sealing brushes used in such tunnel boring machines used, for example, for the production of subway or road tunnels seal against the soil and retain groundwater. During the drilling process, an additional sealant is introduced into the area of the sealing brushes, such as a suitable sealing grease. The sealing brushes are due to the nature of their use to a certain wear and it is necessary with increasing wear of Abdichtbürsten to introduce a greater amount of the sealant in the range of Abdichtbürsten to ensure adequate sealing. As the amount of sealant to be introduced increases with the wear of the sealing brushes, the operating costs of using the tunnel boring machine increase steadily until a point is reached at which it is less expensive to replace the Abdichtbürsten as an ever-increasing amount of the sealant initiate.
Bei den oben beschriebenen, aus dem Stand der Technik bekannten Lösungen weisen die Abdichtbürsten Halteplatten auf, die vorzugsweise an zwei Punkten mit einem Grundelement der Tunnelbohrmaschine verschweißt sind. Zum Austauschen der Abdichtbürsten müssen diese Schweißverbindungen gelöst werden, was meist mittels Trennschneiden ausgeführt wird und mit einem sehr hohen Aufwand verbunden ist. Da sich die Tunnelbohrmaschine und somit auch die an derselben angebrachten Abdichtbürsten in einem sehr schmutzigen Umfeld befinden, ist dieses Auftrennen der Schweißverbindungen eine sehr unangenehme und teilweise auch gefährliche Arbeit, die außerdem sehr zeitintensiv ist und verhältnismäßig lange Stillstandszeiten der Tunnelbohrmaschine nach sich zieht. Aus diesem Grund ist das Austauschen der Abdichtbürsten stets mit relativ hohen Kosten verbunden und wird meist erst dann durchgeführt, wenn die Kosten für das in den Bereich der Abdichtbürsten eingeleitete Abdichtmittel auf eine nicht mehr hinnehmbare Höhe ansteigen, oder wenn die Abdichtbürsten derart verschlissen sind, dass auch durch die Einleitung einer sehr hohen Menge an Abdichtmittel keine sichere Abdichtung mehr gewährleistet werden kann.In the solutions described above, known from the prior art, the sealing brushes on holding plates, which are preferably welded at two points with a base element of the tunnel boring machine. To replace the sealing brushes these welds must be solved, which is usually carried out by means of cutting and is associated with a very high cost. Since the tunnel boring machine and thus also attached to the sealing brushes are in a very dirty environment, this separation of the welded joints is a very unpleasant and sometimes dangerous work, which is also very time consuming and relatively long downtime of the tunnel boring machine. For this reason, replacement of the sealing brushes is always associated with a relatively high cost and is usually only performed when the cost of the sealing means introduced into the area of the sealing brushes increases to an unacceptable level, or if the sealing brushes are worn so badly that Even by the introduction of a very high amount of sealant no secure seal more can be guaranteed.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Befestigung einer Abdichtbürste an einer Tunnelbohrmaschine zu schaffen, die ein einfaches Lösen und Befestigen der Abdichtbürste ermöglicht.It is therefore an object of the present invention to provide a device for fastening a sealing brush to a tunnel boring machine, which allows easy release and fixing of the sealing brush.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention, this object is achieved by the features mentioned in
Durch die erfindungsgemäße formschlüssige Verbindung, die durch das Zusammenwirken zumindest eines der Befestigungselemente einerseits und der Halteplatte der Abdichtbürste andererseits erzeugt wird, ergibt sich eine sehr einfache Möglichkeit zum Lösen der Abdichtbürste von dem entsprechenden Befestigungselement, da auf Trennschneiden oder ähnliches verzichtet werden kann und lediglich die Abdichtbürste aus dem entsprechenden Befestigungselement entnommen werden muss.By the positive connection according to the invention, which is generated by the interaction of at least one of the fasteners on the one hand and the retaining plate of the sealing brush on the other hand, results in a very simple way to release the sealing brush of the corresponding Fastening element, as can be dispensed with cutting blades or the like and only the sealing brush must be removed from the corresponding fastener.
Dadurch wird die zum Austauschen einer Abdichtbürste erforderliche Zeit erheblich verkürzt, wodurch sich sehr viel geringere Stillstandszeiten der mit diesen Abdichtbürsten ausgestatteten Tunnelbohrmaschine ergeben, so dass erhebliche Kosten eingespart werden können. Gegenüber bekannten Lösungen kann daher das Austauschen der Bürsten zu einem früheren Zeitpunkt durchgeführt werden, so dass zusätzlich zu der Zeiteinsparung auch die sehr hohen Kosten für das in großer Menge in den Bereich der Abdichtbürsten eingeleitete Abdichtmittel reduziert werden können.As a result, the time required to replace a sealing brush is significantly shortened, resulting in much lower downtime of equipped with these Abdichtbürsten tunnel boring machine, so that considerable costs can be saved. Compared to known solutions, therefore, the replacement of the brushes can be carried out at an earlier time, so that in addition to the time savings and the very high cost of the initiated in large quantities in the field of Abdichtbürsten sealant can be reduced.
In einer sehr vorteilhaften Weiterbildung der Erfindung kann vorgesehen sein, dass die Halteplatte durch lediglich eines der Befestigungselemente mittels einer formschlüssigen Verbindung gehalten ist, welche sich auf der Seite der Halteplatte der Abdichtbürste befindet, über die sich ein Bürstenkopf der Abdichtbürste erstreckt. Auf diese Weise ist eine sehr einfache Montage der Abdichtbürste auf dem Grundelement der Tunnelbohrmaschine möglich, da lediglich eine formschlüssige Verbindung hergestellt werden muss. Da der Bürstenkopf der Abdichtbürste bei bekannten Lösungen meist ein sehr großes Hindernis bei der Montage und insbesondere der Demontage der Abdichtbürste von dem Grundelement darstellt, ist es besonders vorteilhaft, die formschlüssige Verbindung an derjenigen Seite vorzusehen, über die sich dieser Bürstenkopf erstreckt, da gerade an dieser Stelle ein hohes Potenzial zur Einsparung von Zeit vorhanden ist.In a very advantageous development of the invention can be provided that the holding plate is held by only one of the fasteners by means of a positive connection, which is located on the side of the holding plate of the sealing brush over which a brush head of the sealing brush extends. In this way, a very simple installation of the sealing brush on the base element of the tunnel boring machine is possible because only a positive connection must be made. Since the brush head of the sealing brush in known solutions usually represents a very large obstacle in the assembly and in particular the dismantling of the sealing brush of the base element, it is particularly advantageous to provide the positive connection on that side over which extends the brush head, there just This site has a high potential for saving time.
In diesem Zusammenhang kann vorgesehen sein, dass die nicht mit einer formschlüssigen Verbindung befestigte Seite der Halteplatte mit dem Befestigungselement verschweißt ist. Da die dem Bürstenkopf der Abdichtbürste abgelegene Seite der Halteplatte meist sehr viel leichter von außen zugänglich ist, stellt es nur ein geringes Problem dar, wenn an dieser Seite eine Schweißnaht hergestellt oder aufgetrennt werden muss.In this connection it can be provided that the side of the retaining plate not fastened with a positive connection is welded to the fastening element. Since the brush head of the sealing brush remote side of the holding plate usually much more easily accessible from the outside is, it represents only a small problem, if at this site a weld must be made or separated.
Alternativ zu dieser Lösung kann jedoch auch vorgesehen sein, dass die formschlüssige Verbindung auf beiden Seiten der Halteplatte mittels der jeweiligen Befestigungselemente vorgesehen ist. Dadurch kann bei der Montage auf einen Schweißvorgang und demzufolge bei der Demontage auf ein Auftrennen einer zuvor hergestellten Schweißnaht verzichtet werden, wodurch insbesondere die Demontage erheblich vereinfacht wird.As an alternative to this solution, however, it can also be provided that the positive connection is provided on both sides of the retaining plate by means of the respective fastening elements. As a result, it is possible to dispense with a separation of a previously produced weld seam during assembly to a welding operation and, consequently, during disassembly, whereby in particular the disassembly is considerably simplified.
Eine sehr einfache Herstellung der formschlüssigen Verbindung ergibt sich, wenn die wenigstens eine formschlüssige Verbindung ein die Halteplatte der Abdichtbürste übergreifendes Element aufweist. Durch ein solches die Halteplatte übergreifendes Element ergibt sich eine zuverlässige Befestigung der Halteplatte und somit der gesamten Abdichtbürste.A very simple production of the positive connection results when the at least one positive connection has a holding plate of the sealing brush cross-element. By such a holding plate cross-over element results in a reliable attachment of the holding plate and thus the entire sealing brush.
Dabei kann vorgesehen sein, dass das die Halteplatte übergreifende Element als die Halteplatte übergreifender Vorsprung ausgebildet ist. Mittels eines solchen Vorsprungs lässt sich die Halteplatte der Abdichtbürste besonders einfach auf dem Grundelement der Tunnelbohrmaschine befestigen.It can be provided that the holding plate cross-element is designed as the holding plate cross-projection. By means of such a projection, the holding plate of the sealing brush can be attached particularly easily to the base element of the tunnel boring machine.
Eine weitere Möglichkeit zur Bildung der formschlüssigen Verbindung mittels eines solchen Elements ergibt sich, wenn in einer weiteren vorteilhaften Ausgestaltung der Erfindung das die Halteplatte übergreifende Element eine Schrägfläche aufweist, die so gegenüber einer Schrägfläche der Halteplatte angeordnet ist, dass die Schrägfläche des übergreifenden Elements an der Schrägfläche der Halteplatte anliegt.Another possibility for forming the positive connection by means of such an element results when, in a further advantageous embodiment of the invention, the holding plate cross-member has an inclined surface which is arranged opposite an inclined surface of the holding plate, that the inclined surface of the cross-member on the Sloping surface of the holding plate rests.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass die Befestigungselemente mit dem Grundelement verschweißt sind. Dies stellt eine besonders einfache Möglichkeit zur Verbindung der Befestigungselemente mit dem Grundelement dar.In a further advantageous embodiment of the invention can be provided that the fastening elements are welded to the base member. This represents a particularly simple way to connect the fasteners with the base element.
Alternativ dazu kann vorgesehen sein, dass die Befestigungselemente mit dem Grundelement verschraubt sind. Auch durch ein solches Verschrauben lassen sich die Befestigungselemente in einfacher Weise an dem Grundelement anbringen.Alternatively, it can be provided that the fastening elements are screwed to the base element. Even by such screwing, the fasteners can be attached to the base element in a simple manner.
Eine Tunnelbohrmaschine mit einem Grundelement, auf dem mehrere Abdichtbürsten mittels einer erfindungsgemäßen Vorrichtung befestigt sind, ergibt sich aus den Merkmalen des Anspruchs 10.A tunnel boring machine with a base element, on which a plurality of sealing brushes are fastened by means of a device according to the invention, results from the features of
