Definitions
- the invention relates to a device for connecting a mast to a ground-mounted mast base.
- a mast base When erecting masts of all kinds, it is common to first anchor a mast base in the ground.
- the publication shows an example of a suitable mast base EP 1 643 056 B1 . It can be anchored, for example, by driving piles or pipes into it, or using a concrete foundation. The mast is then erected with a crane, brought into position and firmly connected to the mast base.
- the mast can be separated from the mast base and, for example, lowered using a crane, so that the maintenance work can be carried out on the ground.
- This solution is also very complex, especially if the mast is set up in a location that is difficult for a crane to access.
- GB 560,852 A discloses an apparatus for connecting a mast to a base plate.
- the device has a holding plate with a bayonet lock for fixing the mast on the holding plate.
- the holding plate can be swiveled around a horizontal axis. It is not possible to rotate the erected mast around its longitudinal axis.
- US 4,932,176 A discloses a telescopic mast system with a telescopic mast that consists of several tubes. The erected telescopic mast cannot be rotated around its longitudinal axis.
- WO 2010/050993 relates to a light pole, which is attached to a mast base.
- EP 1 916 360 A2 discloses struts of a building, the position of which cannot be changed after the beams and walls have been attached.
- the connection between the mast and mast base is thus established via a base plate which is connected to the mast base and a tilting plate which is connected to the mast.
- the base plate and the tilt plate are referred to as plates for the sake of simplicity. They can have a plate-like basic shape, but can also deviate from it.
- the base plate and / or tilting plate can also have a tubular section shape with a fastening flange or a block or box-shaped shape.
- the mast connected to the tilting plate can be tilted relative to the mast base connected to the base plate.
- the device offers the possibility of rotating the mast relative to the mast base.
- the device has a rotary guide which is designed either on the base plate or on the tilting plate. The rotary movement takes place about a longitudinal axis of the mast, which is arranged essentially vertically in the erected position of the mast.
- the longitudinal axis of the mast can run along a central axis of a vertical mast section, but also at a lateral distance therefrom.
- the first fastening device serves to fix the tilting plate and the base plate in a substantially parallel position relative to one another. This position corresponds to an upright position of the mast. So that the base plate and tilting plate exactly after the execution of a tilting movement into the intended, substantially parallel Position, the base plate may have a centering pin which engages in a bore of the tilting plate when the mast is erected, or vice versa.
- the second fastening device can block the rotary movement.
- the invention includes two alternatives for the rotary guide and the second fastening device assigned to the rotary movement.
- Either the rotary guide is assigned to the base plate and causes a rotary movement of the base plate relative to the mast base.
- the second fastening device serves to fix the base plate relative to the mast base.
- the rotating guide can be assigned to the tilting plate and can cause a rotating movement of the mast relative to the tilting plate.
- the second fastening device serves to fix the tilting plate relative to the mast.
- the invention enables a controlled lowering and re-erection of the mast in a position that is particularly suitable for the upcoming maintenance work. Due to the possibility of rotating the mast relative to the mast base, a lateral arm of the mast in particular can first be shifted into a plane in which the mast is to be tilted. While the rotary movement is being carried out, the mast can be prevented from tipping with the aid of the first fastening device. After the rotational movement has been carried out, the desired rotational position can be fixed with the aid of the second fastening device, so that it is retained for a subsequent tilting process.
- the procedure made possible by the invention is ideal, for example, for servicing a mast erected on the side of a track system, which has a lateral arm located above the track system in the erected state.
- the side jib By rotating the mast as described and tilting it laterally, the side jib can keep free from an overhead line and from a room directly above the track system become. This minimizes the impact on rail traffic.
- the entire mast, including the side arm is easily accessible to the side of the track system, so that the maintenance work can also be carried out essentially without affecting rail traffic.
- the mast can then be brought back into its working position in reverse order, namely by first reversing the tilting movement and fixing the upright position of the mast with the aid of the first fastening device. Then the rotary movement can also be reversed and the mast can be fixed in its working position with the help of the second fastening device.
- the base plate and the tilting plate are connected to one another in a hinge-like manner by means of a bolt.
- the bolt can run along two lateral edges of the two plates. In this way, a simple and robust definition of the swivel axis is achieved.
- the bolt can be passed through openings in the base plate and in the tilting plate.
- the bolt can be integrally connected to the base plate or to the tilting plate, in particular by welding.
- the first fastening device has at least one threaded bolt which can be inserted into an opening in the base plate and in an opening in the tilting plate.
- the threaded bolt clamps the base plate and tilting plate together. An easy-to-use and secure attachment is achieved in this way.
- the opening of the base plate or the opening of the tilting plate for the at least one threaded bolt of the first fastening device has a threaded bore into which the at least one threaded bolt of the first fastening device can be screwed.
- a threaded section of the threaded bolt through both openings and secured with a nut.
- screwing into a threaded bore of the plate in question represents a further simplification.
- the plate in question can simply be provided with sufficient strength to enable a secure screw connection.
- the base plate and the tilt plate have a square basic shape and the first fastening device has four threaded bolts, the associated openings in the base plate and in the tilt plate being arranged on the longitudinal edges of the base plate and tilt plate.
- the first fastening device In order to prevent the mast from tipping over, the first fastening device must be able to absorb large loads, for example in the event of a storm. Threaded bolts arranged at a large distance from one another on the longitudinal edges of the plates in question can absorb these loads well.
- the rotary guide has a pin or an opening which determines an axis of rotation of the rotary movement.
- the base plate can have a pin which engages in a corresponding opening in the mast base.
- the pin can be circular cylindrical.
- the pin can be solid or hollow, for example in the form of a tube section.
- the base plate can have, for example, a circular cylindrical opening into which a corresponding pin engages on the mast base.
- the rotary guide is formed on the tilt plate. There, too, it can be realized, for example, in the form of a pin or an opening, as explained for the base plate.
- the rotary guide has at least one ring segment-shaped groove and a fastening element which is guided through the groove.
- the fastening element can, for example, be a threaded bolt, the head of which engages behind the groove.
- the groove may have a step against which a head of the fastener abuts, the step may be at a depth greater than or equal to a height of the head so that the head of the fastener sinks into the plate having the groove is arranged and does not survive the plate in question.
- the fastening element can not only fix the lateral position of the axis of rotation, but at the same time hold the plate having the groove together with the element interacting therewith (i.e. the mast base or the mast) in order to prevent the axis of rotation from tilting.
- the rotary guide has two stops which limit a possible angle of rotation.
- the angle of rotation can be limited to a range of 90 °.
- the stops can in particular be formed by the ends of the annular segment-shaped groove and one or more fastening elements interacting therewith.
- the second fastening device has a plurality of threaded bolts which can be used in openings either (i) in the base plate and in the mast base or (ii) in the tilting plate and in a base plate of the mast.
- a particularly reliable blocking of the rotary movement is thus achieved in that the plate, which has the rotary guide, is firmly screwed to the element which can be rotated relative to it.
- the openings for the threaded bolts of the second fastening device are arranged such that each of the threaded bolts can be inserted in two of the openings in at least two different rotational positions of the mast relative to the mast base. This makes it easy to determine the rotational position in the relevant positions, for example at an angular distance of 90 ° from one another.
- the base plate and the tilt plate have a square basic shape and the second fastening device has four threaded bolts, the associated openings in the base plate or in the tilt plate being arranged at the corners of the base plate or tilt plate.
- This arrangement of the threaded bolts is optimal for the desired fixation of the rotary movement.
- a conflict with the threaded bolts of the first fastening device is avoided, even when using different rotational positions.
- the openings for the threaded bolts of the second fastening device each have a threaded bore in the base plate or in the tilting plate, into which one of the threaded bolts of the second fastening device can be screwed.
- the device comprises a mast base which can be anchored to the ground and which can be connected to the base plate.
- the mast base can be matched to the base plate in terms of its dimensions and other properties.
- the mast base has a mast base adapter with a tubular section which is designed for connection to a ramming tube or pile.
- mast base adapters are known for establishing signal or lighting masts in particular. They form a solid base for connection to a base plate.
- the mast base has a base plate on its upper side, in which a circular opening is formed, into which a pin of the rotary guide formed on the base plate engages.
- the base plate is then rotatable about the common central axis of the pin and opening relative to the base plate.
- the device comprises a mast that is connectable to the tilting plate.
- the mast has a base plate which can be connected to the tilting plate, in particular by screwing.
- it can be a conventional mast, the base plate of which, according to the prior art, was screwed directly onto a mast base. In this way, such a conventional mast can be used with the device according to the invention.
- the footplate has openings through which the threaded bolts of the first fastening device can be passed.
- the relative position of the base plate and tilting plate can be fixed with threaded bolts which not only engage in openings in the base plate and the tilting plate, but are additionally passed through the opening in the footplate. It is therefore possible to loosen and fix the first fastening device "through the base plate" without having to make extensive adjustments to the conventional mast with base plate.
- the tilting plate is permanently connected to the mast, in particular by welding.
- the mast does not need a base plate, but is directly and permanently connected to the tilt plate.
- the mast is a signal or lighting mast for installation on a traffic route, in particular on a track system.
- the mast can in particular have a lateral arm.
- the device comprises a hydraulic tilting device which can be connected to the mast base and to the mast and is designed to enable controlled tilting and re-erection of the mast.

Description
Die Erfindung betrifft eine Vorrichtung zur Verbindung eines Masts mit einem erdbodenfesten Mastsockel. Bei der Errichtung von Mästen aller Art ist es üblich, zunächst einen Mastsockel im Erdboden zu verankern. Ein Beispiel eines geeigneten Mastsockels zeigt die Druckschrift
Wartungsarbeiten an einem solchen Mast sind auf zweierlei Weise möglich. Entweder werden sie bei aufgestelltem Mast ausgeführt, wozu sich eine Person nach oben bewegen muss. Hierzu kann sie entweder den Mast erklettern oder sich beispielsweise einer anhebbaren Arbeitsbühne bedienen. Diese Lösung ist aufwendig, weil bei Arbeiten in großer Höhe strenge Sicherheitsanforderungen einzuhalten sind. Außerdem kann die Zugänglichkeit des Masts eingeschränkt oder mit weiteren Gefahren verbunden sein, etwa wenn sich in der Nähe des Masts Oberleitungen befinden.Maintenance work on such a mast is possible in two ways. They are either carried out with the mast erected, for which a person has to move upwards. To do this, they can either climb the mast or use a lifting platform, for example. This solution is complex because strict safety requirements must be met when working at great heights. In addition, the accessibility of the mast can be restricted or associated with further dangers, for example if overhead lines are in the vicinity of the mast.
Alternativ kann der Mast von dem Mastsockel getrennt und beispielsweise mit Hilfe eines Krans abgesenkt werden, sodass die Wartungsarbeiten am Boden ausgeführt werden können. Auch diese Lösung ist sehr aufwendig, insbesondere wenn der Mast an einem für einen Kran nur schwer zugänglichen Ort aufgestellt ist.Alternatively, the mast can be separated from the mast base and, for example, lowered using a crane, so that the maintenance work can be carried out on the ground. This solution is also very complex, especially if the mast is set up in a location that is difficult for a crane to access.
Zudem bedeuten die beiden skizzierten Lösungen für Wartungsarbeiten unter Umständen erhebliche Beeinträchtigungen der Nutzbarkeit von in der Nähe des Masts befindlichen Verkehrswegen. Häufig müssen Bahnstrecken oder Straßen, an denen der zu wartende Mast aufgestellt ist, gesperrt oder eine Umgebung des Masts muss in geeigneter Weise abgesichert werden.In addition, the two outlined solutions for maintenance work can mean significant impairments to the usability of traffic routes located near the mast. Often, railway lines or roads on which the mast to be serviced is installed must be closed or an area surrounding the mast must be adequately secured.
Davon ausgehend ist es die Aufgabe der Erfindung, eine Vorrichtung zur Verbindung eines Masts mit einem erdbodenfesten Mastsockel zur Verfügung zu stellen, die Wartungsarbeiten an dem Mast vereinfacht.Based on this, it is the object of the invention to provide a device for connecting a mast to a ground-mounted mast base, which simplifies maintenance work on the mast.
Diese Aufgabe wird gelöst durch die Vorrichtung mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind in den sich anschließenden Unteransprüchen angegeben.This object is achieved by the device with the features of claim 1. Advantageous refinements are specified in the subsequent subclaims.
Die Vorrichtung dient zur Verbindung eines Masts mit einem erdbodenfesten Mastsockel und weist folgendes auf:
- einen Mastsockel,
- eine Grundplatte zur Verbindung mit dem Mastsockel,
- eine Kippplatte zur Verbindung mit dem Mast,
- wobei die Kippplatte und die Grundplatte schwenkbar miteinander verbunden sind, so dass die Kippplatte relativ zu der Grundplatte gekippt werden kann,
- eine erste Befestigungseinrichtung, mit der die Kippplatte und die Grundplatte relativ zueinander in einer im Wesentlichen parallelen Stellung fixiert werden können,
- eine Drehführung, die eine Drehbewegung des Masts relativ zu dem Mastsockel um eine Längsachse des Masts ermöglicht, wenn der Mast mit der Kippplatte und der Mastsockel mit der Grundplatte verbunden und die Kippplatte und die Grundplatte in der im Wesentlichen parallelen Stellung fixiert sind,
- eine zweite Befestigungseinrichtung, mit der die Drehbewegung des Masts relativ zu dem Mastsockel um eine Längsachse des Masts blockiert werden kann, wobei entweder (i) die Grundplatte die Drehführung aufweist und die zweite Befestigungseinrichtung dazu ausgebildet ist, die Grundplatte relativ zu dem Mastsockel zu fixieren, oder (ii) die Kippplatte die Drehführung aufweist und die zweite Befestigungseinrichtung dazu ausgebildet ist, die Kippplatte an dem Mast zu fixieren.
- a mast base,
- a base plate for connection to the mast base,
- a tilting plate for connection to the mast,
- wherein the tilt plate and the base plate are pivotally connected to one another so that the tilt plate can be tilted relative to the base plate,
- a first fastening device with which the tilting plate and the base plate can be fixed in a substantially parallel position relative to one another,
- a rotating guide that allows the mast to rotate relative to the mast base about a longitudinal axis of the mast when the mast is with the tilting plate and the mast base is connected to the base plate and the tilting plate and the base plate are fixed in the substantially parallel position,
- a second fastening device with which the rotational movement of the mast relative to the mast base about a longitudinal axis of the mast can be blocked, wherein either (i) the base plate has the rotary guide and the second fastening device is designed to be the base plate to be fixed relative to the mast base, or (ii) the tilting plate has the rotary guide and the second fastening device is designed to fix the tilting plate to the mast.
Bei der Erfindung wird die Verbindung zwischen Mast und Mastsockel also über eine Grundplatte, die mit dem Mastsockel verbunden ist, und eine Kippplatte, die mit dem Mast verbunden ist, hergestellt. Die Grundplatte und die Kippplatte werden der Einfachheit halber als Platten bezeichnet. Sie können eine plattenförmige Grundform aufweisen, davon jedoch auch abweichen. Beispielsweise können Grund- und/oder Kippplatte auch eine rohrabschnittsförmige Gestalt mit einem Befestigungsflansch oder eine block- oder kastenförmige Gestalt haben.In the invention, the connection between the mast and mast base is thus established via a base plate which is connected to the mast base and a tilting plate which is connected to the mast. The base plate and the tilt plate are referred to as plates for the sake of simplicity. They can have a plate-like basic shape, but can also deviate from it. For example, the base plate and / or tilting plate can also have a tubular section shape with a fastening flange or a block or box-shaped shape.
Durch die schwenkbare Verbindung zwischen Kippplatte und Grundplatte kann der mit der Kippplatte verbundene Mast relativ zu dem mit der Grundplatte verbundenen Mastsockel gekippt werden. Zusätzlich bietet die Vorrichtung die Möglichkeit, den Mast relativ zu dem Mastsockel zu drehen. Hierzu weist die Vorrichtung eine Drehführung auf, die entweder an der Grundplatte oder an der Kippplatte ausgebildet ist. Die Drehbewegung erfolgt um eine Längsachse des Masts, die in der aufgerichteten Stellung des Masts im Wesentlichen vertikal angeordnet ist. Die Längsachse des Masts kann entlang einer Mittelachse eines vertikalen Mastabschnitts verlaufen, aber auch in einem seitlichen Abstand davon.Due to the pivotable connection between the tilting plate and base plate, the mast connected to the tilting plate can be tilted relative to the mast base connected to the base plate. In addition, the device offers the possibility of rotating the mast relative to the mast base. For this purpose, the device has a rotary guide which is designed either on the base plate or on the tilting plate. The rotary movement takes place about a longitudinal axis of the mast, which is arranged essentially vertically in the erected position of the mast. The longitudinal axis of the mast can run along a central axis of a vertical mast section, but also at a lateral distance therefrom.
Außerdem gibt es zwei Befestigungseinrichtungen, mit denen die Schwenk- und die Drehbewegung getrennt voneinander blockiert werden können. Die erste Befestigungseinrichtung dient dazu, die Kippplatte und die Grundplatte relativ zueinander in einer im Wesentlichen parallelen Stellung zu fixieren. Diese Stellung entspricht einer aufrechten Stellung des Masts. Damit Grundplatte und Kippplatte nach dem Ausführen einer Kippbewegung exakt in die vorgesehene, im Wesentlichen parallele Stellung gelangen, kann die Grundplatte einen Zentrierdorn aufweisen, der beim Aufrichten des Masts in eine Bohrung der Kippplatte eingreift, oder umgekehrt. Die zweite Befestigungseinrichtung kann die Drehbewegung blockieren.There are also two fastening devices with which the swiveling and rotating movements can be blocked separately. The first fastening device serves to fix the tilting plate and the base plate in a substantially parallel position relative to one another. This position corresponds to an upright position of the mast. So that the base plate and tilting plate exactly after the execution of a tilting movement into the intended, substantially parallel Position, the base plate may have a centering pin which engages in a bore of the tilting plate when the mast is erected, or vice versa. The second fastening device can block the rotary movement.
Für die Drehführung und die der Drehbewegung zugeordnete, zweite Befestigungseinrichtung schließt die Erfindung zwei Alternativen ein. Entweder ist die Drehführung der Grundplatte zugeordnet und bewirkt eine Führung einer Drehbewegung der Grundplatte relativ zu dem Mastsockel. In diesem Fall dient die zweite Befestigungseinrichtung zur Fixierung der Grundplatte relativ zu dem Mastsockel. Alternativ kann die Drehführung der Kippplatte zugeordnet sein und eine Führung einer Drehbewegung des Masts relativ zu der Kippplatte bewirken. In diesem Fall dient die zweite Befestigungseinrichtung zur Fixierung der Kippplatte relativ zu dem Mast.The invention includes two alternatives for the rotary guide and the second fastening device assigned to the rotary movement. Either the rotary guide is assigned to the base plate and causes a rotary movement of the base plate relative to the mast base. In this case, the second fastening device serves to fix the base plate relative to the mast base. Alternatively, the rotating guide can be assigned to the tilting plate and can cause a rotating movement of the mast relative to the tilting plate. In this case, the second fastening device serves to fix the tilting plate relative to the mast.
Die Erfindung ermöglicht ein kontrolliertes Absenken und Wiederaufstellen des Masts in einer für die anstehenden Wartungsarbeiten besonders geeigneten Stellung. Durch die Möglichkeit, den Mast relativ zum Mastsockel zu drehen, kann insbesondere ein seitlicher Ausleger des Masts zunächst in eine Ebene verlagert werden, in der der Mast verkippt werden soll. Während des Ausführens der Drehbewegung kann ein Kippen des Masts mit Hilfe der ersten Befestigungseinrichtung ausgeschlossen werden. Nach dem Ausführen der Drehbewegung kann mit Hilfe der zweiten Befestigungseinrichtung die gewünschte Drehstellung fixiert werden, sodass sie für einen nachfolgenden Kippvorgang erhalten bleibt. Das durch die Erfindung ermöglichte Vorgehen ist ideal, um beispielsweise einen seitlich einer Gleisanlage errichteten Mast zu warten, der einen im aufgerichteten Zustand oberhalb der Gleisanlage befindlichen, seitlichen Ausleger aufweist. Durch das beschriebene Drehen des Masts und das nachfolgende Kippen kann der seitliche Ausleger von einer Oberleitung und von einem Raum unmittelbar oberhalb der Gleisanlage freigehalten werden. Dadurch werden Beeinträchtigungen des Schienenverkehrs minimiert. Nach dem Kippen des Masts befindet sich der gesamte Mast einschließlich des seitlichen Auslegers gut zugänglich seitlich der Gleisanlage, sodass auch die Wartungsarbeiten im Wesentlichen ohne Beeinträchtigung des Schienenverkehrs ausgeführt werden können. Anschließend kann der Mast in umgekehrter Reihenfolge wieder in seine Arbeitsposition gebracht werden, nämlich indem zunächst die Kippbewegung rückgängig gemacht und die aufgerichtete Stellung des Masts mit Hilfe der ersten Befestigungseinrichtung fixiert wird. Anschließend kann die Drehbewegung ebenfalls wieder rückgängig gemacht und der Mast in seiner Arbeitsposition mit Hilfe der zweiten Befestigungseinrichtung fixiert werden.The invention enables a controlled lowering and re-erection of the mast in a position that is particularly suitable for the upcoming maintenance work. Due to the possibility of rotating the mast relative to the mast base, a lateral arm of the mast in particular can first be shifted into a plane in which the mast is to be tilted. While the rotary movement is being carried out, the mast can be prevented from tipping with the aid of the first fastening device. After the rotational movement has been carried out, the desired rotational position can be fixed with the aid of the second fastening device, so that it is retained for a subsequent tilting process. The procedure made possible by the invention is ideal, for example, for servicing a mast erected on the side of a track system, which has a lateral arm located above the track system in the erected state. By rotating the mast as described and tilting it laterally, the side jib can keep free from an overhead line and from a room directly above the track system become. This minimizes the impact on rail traffic. After the mast has been tilted, the entire mast, including the side arm, is easily accessible to the side of the track system, so that the maintenance work can also be carried out essentially without affecting rail traffic. The mast can then be brought back into its working position in reverse order, namely by first reversing the tilting movement and fixing the upright position of the mast with the aid of the first fastening device. Then the rotary movement can also be reversed and the mast can be fixed in its working position with the help of the second fastening device.
In einer Ausgestaltung sind die Grundplatte und die Kippplatte scharnierartig über einen Bolzen miteinander verbunden. Der Bolzen kann entlang zweier seitlicher Ränder der beiden Platten verlaufen. Auf diese Weise wird eine einfache und robuste Festlegung der Schwenkachse erzielt. Der Bolzen kann durch Öffnungen in der Grundplatte und in der Kippplatte hindurchgeführt sein. Alternativ kann der Bolzen mit der Grundplatte oder mit der Kippplatte stoffschlüssig verbunden sein, insbesondere durch Verschweißen.In one embodiment, the base plate and the tilting plate are connected to one another in a hinge-like manner by means of a bolt. The bolt can run along two lateral edges of the two plates. In this way, a simple and robust definition of the swivel axis is achieved. The bolt can be passed through openings in the base plate and in the tilting plate. Alternatively, the bolt can be integrally connected to the base plate or to the tilting plate, in particular by welding.
In einer Ausgestaltung weist die erste Befestigungseinrichtung mindestens einen Gewindebolzen auf, der in eine Öffnung der Grundplatte und in eine Öffnung der Kippplatte einsetzbar ist. Der Gewindebolzen verspannt Grundplatte und Kippplatte miteinander. So wird eine einfach handhabbare und sichere Befestigung erreicht.In one configuration, the first fastening device has at least one threaded bolt which can be inserted into an opening in the base plate and in an opening in the tilting plate. The threaded bolt clamps the base plate and tilting plate together. An easy-to-use and secure attachment is achieved in this way.
In einer Ausgestaltung weist die Öffnung der Grundplatte oder die Öffnung der Kippplatte für den mindestens einen Gewindebolzen der ersten Befestigungseinrichtung eine Gewindebohrung auf, in die der mindestens eine Gewindebolzen der ersten Befestigungseinrichtung einschraubbar ist. Alternativ kann ein Gewindeabschnitt des Gewindebolzens durch beide Öffnungen hindurchgesteckt und mit einer Mutter gesichert werden. Das Einschrauben in eine Gewindebohrung der betreffenden Platte selbst stellt demgegenüber eine weitere Vereinfachung dar. Die betreffende Platte kann einfach mit einer ausreichenden Stärke versehen werden, um eine sichere Schraubverbindung zu ermöglichen.In one configuration, the opening of the base plate or the opening of the tilting plate for the at least one threaded bolt of the first fastening device has a threaded bore into which the at least one threaded bolt of the first fastening device can be screwed. Alternatively, a threaded section of the threaded bolt through both openings and secured with a nut. In contrast, screwing into a threaded bore of the plate in question represents a further simplification. The plate in question can simply be provided with sufficient strength to enable a secure screw connection.
In einer Ausgestaltung weisen die Grundplatte und die Kippplatte eine quadratische Grundform auf und die erste Befestigungseinrichtung weist vier Gewindebolzen auf, wobei die zugehörigen Öffnungen in der Grundplatte und in der Kippplatte an den Längskanten von Grundplatte und Kippplatte angeordnet sind. Um ein Kippen des Masts zu verhindern, muss die erste Befestigungseinrichtung große Lasten aufnehmen können, beispielsweise bei Sturm. In großem Abstand voneinander angeordnete Gewindebolzen an den Längskanten der betreffenden Platten können diese Lasten gut aufnehmen.In one embodiment, the base plate and the tilt plate have a square basic shape and the first fastening device has four threaded bolts, the associated openings in the base plate and in the tilt plate being arranged on the longitudinal edges of the base plate and tilt plate. In order to prevent the mast from tipping over, the first fastening device must be able to absorb large loads, for example in the event of a storm. Threaded bolts arranged at a large distance from one another on the longitudinal edges of the plates in question can absorb these loads well.
In einer Ausgestaltung weist die Drehführung einen Zapfen oder eine Öffnung auf, der eine Drehachse der Drehbewegung bestimmt. Beispielsweise kann die Grundplatte einen Zapfen aufweisen, der in eine korrespondierende Öffnung im Mastsockel eingreift. Der Zapfen kann kreiszylindrisch sein. Der Zapfen kann massiv oder hohl ausgeführt sein, beispielsweise in Form eines Rohrabschnitts. Alternativ kann die Grundplatte eine beispielsweise kreiszylindrische Öffnung aufweisen, in die ein korrespondierender Zapfen am Mastsockel eingreift. In weiteren Varianten ist die Drehführung an der Kippplatte ausgebildet. Auch dort kann sie beispielsweise in Form eines Zapfens oder einer Öffnung realisiert werden, wie zu der Grundplatte erläutert.In one embodiment, the rotary guide has a pin or an opening which determines an axis of rotation of the rotary movement. For example, the base plate can have a pin which engages in a corresponding opening in the mast base. The pin can be circular cylindrical. The pin can be solid or hollow, for example in the form of a tube section. Alternatively, the base plate can have, for example, a circular cylindrical opening into which a corresponding pin engages on the mast base. In other variants, the rotary guide is formed on the tilt plate. There, too, it can be realized, for example, in the form of a pin or an opening, as explained for the base plate.
In einer Ausgestaltung weist die Drehführung mindestens eine ringsegmentförmige Nut auf und ein Befestigungselement, das durch die Nut hindurchgeführt ist. Durch das Zusammenwirken von Befestigungselement und Nut wird die Drehbewegung geführt. Durch den Winkelbereich, über den sich die ringsegmentförmige Nut erstreckt, kann gleichzeitig ein zulässiger Drehbereich festgelegt werden, wobei die Enden der Nut als Anschläge wirken. Das Befestigungselement kann beispielsweise ein Gewindebolzen sein, dessen Kopf die Nut hintergreift. Die Nut kann eine Stufe aufweisen, an der ein Kopf des Befestigungselements anliegt, wobei sich die Stufe in einer Tiefe befinden kann, die größer oder gleich einer Höhe des Kopfs ist, sodass der Kopf des Befestigungselements in der Platte, die die Nut aufweist, versenkt angeordnet ist und nicht über die betreffende Platte übersteht. Das Befestigungselement kann nicht nur die seitliche Position der Drehachse festlegen, sondern zugleich die Platte, die die Nut aufweist, mit dem damit zusammenwirkenden Element (also dem Mastsockel oder dem Mast) zusammenhalten, um ein Verkippen der Drehachse zu verhindern.In one embodiment, the rotary guide has at least one ring segment-shaped groove and a fastening element which is guided through the groove. By the interaction of the fastening element and the groove leads to the rotary movement. By the angular range over which the ring segment-shaped groove extends, a permissible range of rotation can be defined at the same time, the ends of the groove acting as stops. The fastening element can, for example, be a threaded bolt, the head of which engages behind the groove. The groove may have a step against which a head of the fastener abuts, the step may be at a depth greater than or equal to a height of the head so that the head of the fastener sinks into the plate having the groove is arranged and does not survive the plate in question. The fastening element can not only fix the lateral position of the axis of rotation, but at the same time hold the plate having the groove together with the element interacting therewith (i.e. the mast base or the mast) in order to prevent the axis of rotation from tilting.
In einer Ausgestaltung weist die Drehführung zwei Anschläge auf, die einen möglichen Drehwinkel begrenzen. Beispielsweise kann der Drehwinkel auf einen Bereich von 90° begrenzt werden. Die Anschläge können insbesondere von den Enden der ringsegmentförmigen Nut und einem oder mehreren damit zusammenwirkenden Befestigungselementen gebildet sein.In one embodiment, the rotary guide has two stops which limit a possible angle of rotation. For example, the angle of rotation can be limited to a range of 90 °. The stops can in particular be formed by the ends of the annular segment-shaped groove and one or more fastening elements interacting therewith.
In einer Ausgestaltung weist die zweite Befestigungseinrichtung mehrere Gewindebolzen auf, die in Öffnungen entweder (i) in der Grundplatte und im Mastsockel oder (ii) in der Kippplatte und in einer Fußplatte des Masts einsetzbar sind. Eine besonders zuverlässige Blockierung der Drehbewegung wird also dadurch erreicht, dass die Platte, die die Drehführung aufweist, mit dem relativ dazu drehbaren Element fest verschraubt wird.In one configuration, the second fastening device has a plurality of threaded bolts which can be used in openings either (i) in the base plate and in the mast base or (ii) in the tilting plate and in a base plate of the mast. A particularly reliable blocking of the rotary movement is thus achieved in that the plate, which has the rotary guide, is firmly screwed to the element which can be rotated relative to it.
In einer Ausgestaltung sind die Öffnungen für die Gewindebolzen der zweiten Befestigungseinrichtung so angeordnet, dass jeder der Gewindebolzen in mindestens zwei unterschiedlichen Drehstellungen des Masts relativ zu dem Mastsockel in zwei der Öffnungen einsetzbar ist. Dadurch ist eine einfache Festlegung der Drehstellung in den relevanten Positionen, beispielsweise in einem Winkelabstand von 90° voneinander, möglich.In one configuration, the openings for the threaded bolts of the second fastening device are arranged such that each of the threaded bolts can be inserted in two of the openings in at least two different rotational positions of the mast relative to the mast base. This makes it easy to determine the rotational position in the relevant positions, for example at an angular distance of 90 ° from one another.
In einer Ausgestaltung weisen die Grundplatte und die Kippplatte eine quadratische Grundform auf und die zweite Befestigungseinrichtung weist vier Gewindebolzen auf, wobei die zugehörigen Öffnungen in der Grundplatte bzw. in der Kippplatte an den Ecken von Grundplatte bzw. Kippplatte angeordnet sind. Für die angestrebte Fixierung der Drehbewegung ist diese Anordnung der Gewindebolzen optimal. Gleichzeitig wird ein Konflikt mit den Gewindebolzen der ersten Befestigungseinrichtung, auch bei Verwendung unterschiedlicher Drehstellungen, vermieden.In one configuration, the base plate and the tilt plate have a square basic shape and the second fastening device has four threaded bolts, the associated openings in the base plate or in the tilt plate being arranged at the corners of the base plate or tilt plate. This arrangement of the threaded bolts is optimal for the desired fixation of the rotary movement. At the same time, a conflict with the threaded bolts of the first fastening device is avoided, even when using different rotational positions.
In einer Ausgestaltung weisen die Öffnungen für die Gewindebolzen der zweiten Befestigungseinrichtung in der Grundplatte bzw. in der Kippplatte jeweils eine Gewindebohrung auf, in die einer der Gewindebolzen der zweiten Befestigungseinrichtung einschraubbar ist. Die Vorteile dieser Lösung wurden bereits mit Bezug auf die für die Gewindebolzen der ersten Befestigungsbohrung vorgesehenen Gewindebohrungen erläutert. Alternativ können die Gewindebolzen der zweiten Befestigungseinrichtungen jeweils durch beide Öffnungen hindurchgeführt und mit einer Mutter gesichert werden.In one configuration, the openings for the threaded bolts of the second fastening device each have a threaded bore in the base plate or in the tilting plate, into which one of the threaded bolts of the second fastening device can be screwed. The advantages of this solution have already been explained with reference to the threaded holes provided for the threaded bolts of the first fastening hole. Alternatively, the threaded bolts of the second fastening devices can be passed through both openings and secured with a nut.
In einer Ausgestaltung umfasst die Vorrichtung einen erdbodenfest verankerbaren Mastsockel, der mit der Grundplatte verbindbar ist. Der Mastsockel kann hinsichtlich seiner Abmessungen und sonstigen Eigenschaften auf die Grundplatte abgestimmt sein.In one embodiment, the device comprises a mast base which can be anchored to the ground and which can be connected to the base plate. The mast base can be matched to the base plate in terms of its dimensions and other properties.
In einer Ausgestaltung weist der Mastsockel einen Mastfußadapter mit einem rohrförmigen Abschnitt auf, der zur Verbindung mit einem Rammrohr oder -pfahl ausgebildet ist. Derartige Mastfußadapter sind zur Gründung insbesondere von Signal- oder Beleuchtungsmasten bekannt. Sie bilden eine solide Basis zur Verbindung mit einer Grundplatte.In one embodiment, the mast base has a mast base adapter with a tubular section which is designed for connection to a ramming tube or pile. Such mast base adapters are known for establishing signal or lighting masts in particular. They form a solid base for connection to a base plate.
In einer Ausgestaltung weist der Mastsockel an seiner Oberseite eine Sockelplatte auf, in der eine kreisförmige Öffnung ausgebildet ist, in die ein Zapfen der an der Grundplatte ausgebildeten Drehführung eingreift. Die Grundplatte ist dann um die gemeinsame Mittelachse von Zapfen und Öffnung relativ zu der Sockelplatte drehbar.In one embodiment, the mast base has a base plate on its upper side, in which a circular opening is formed, into which a pin of the rotary guide formed on the base plate engages. The base plate is then rotatable about the common central axis of the pin and opening relative to the base plate.
In einer Ausgestaltung umfasst die Vorrichtung einen Mast, der mit der Kippplatte verbindbar der verbunden ist.In one configuration, the device comprises a mast that is connectable to the tilting plate.
In einer Ausgestaltung weist der Mast eine Fußplatte auf, die mit der Kippplatte verbindbar ist, insbesondere durch Verschrauben. Es kann sich insbesondere um einen herkömmlichen Mast handeln, dessen Fußplatte dem Stand der Technik zufolge unmittelbar mit einem Mastsockel verschraubt wurde. Auf diese Weise kann ein solcher, herkömmlicher Mast mit der erfindungsgemäßen Vorrichtung genutzt werden.In one configuration, the mast has a base plate which can be connected to the tilting plate, in particular by screwing. In particular, it can be a conventional mast, the base plate of which, according to the prior art, was screwed directly onto a mast base. In this way, such a conventional mast can be used with the device according to the invention.
In einer Ausgestaltung weist die Fußplatte Öffnungen auf, durch die die Gewindebolzen der ersten Befestigungseinrichtung hindurchführbar sind. Die relative Stellung von Grundplatte und Kippplatte kann in diesem Fall mit Gewindebolzen fixiert werden, die nicht nur in Öffnungen der Grundplatte und der Kippplatte eingreifen, sondern zusätzlich durch die Öffnung in der Fußplatte hindurchgeführt sind. Das Lösen und Fixieren der ersten Befestigungseinrichtung ist deshalb "durch die Fußplatte hindurch" möglich, ohne dass weitreichende Anpassungen an dem herkömmlichen Mast mit Fußplatte vorgenommen werden müssten.In one embodiment, the footplate has openings through which the threaded bolts of the first fastening device can be passed. In this case, the relative position of the base plate and tilting plate can be fixed with threaded bolts which not only engage in openings in the base plate and the tilting plate, but are additionally passed through the opening in the footplate. It is therefore possible to loosen and fix the first fastening device "through the base plate" without having to make extensive adjustments to the conventional mast with base plate.
In einer Ausgestaltung ist die Kippplatte unlösbar mit dem Mast verbunden, insbesondere durch Schweißen. In diesem Fall benötigt der Mast keine Fußplatte, sondern wird unmittelbar und dauerhaft mit der Kippplatte verbunden.In one embodiment, the tilting plate is permanently connected to the mast, in particular by welding. In this case, the mast does not need a base plate, but is directly and permanently connected to the tilt plate.
In einer Ausgestaltung ist der Mast ein Signal- oder Beleuchtungsmast zur Aufstellung an einem Verkehrsweg, insbesondere an einer Gleisanlage. Der Mast kann insbesondere einen seitlichen Ausleger aufweisen.In one embodiment, the mast is a signal or lighting mast for installation on a traffic route, in particular on a track system. The mast can in particular have a lateral arm.
In einer Ausgestaltung umfasst die Vorrichtung eine hydraulische Kippvorrichtung, die mit dem Mastsockel und mit dem Mast verbindbar und dazu ausgebildet ist, ein kontrolliertes Kippen und Wiederaufrichten des Masts zu ermöglichen. Durch die Führung der Bewegung des Masts genügt eine vergleichsweise einfache Kippvorrichtung, um den Mast sicher zu kippen und wieder aufzurichten. Auf einen Kran oder zusätzliche Maßnahmen zur Führung der Bewegung kann verzichtet werden.In one embodiment, the device comprises a hydraulic tilting device which can be connected to the mast base and to the mast and is designed to enable controlled tilting and re-erection of the mast. By guiding the movement of the mast, a comparatively simple tilting device is sufficient to tilt the mast safely and to straighten it up again. There is no need for a crane or additional measures to guide the movement.
Offenbart wird außerdem ein zusammen mit der vorstehend beschriebenen Vorrichtung, aber auch unabhängig davon ausführbares Verfahren zur Wartung eines Masts, der mit einem erdbodenfesten Mastsockel verbunden ist, das jedoch nicht beansprucht wird.Also disclosed is a method for servicing a mast that can be carried out together with the device described above, but also independently thereof, which is connected to a ground-mounted mast base, but which is not claimed.
