EP3165693B1 - Tiltable device for connecting a mast with a mast socket - Google Patents

Description

The invention relates to a device for connecting a mast to a ground-mounted 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.

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.

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.

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.

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.

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.

This object is achieved by the device with the features of claim 1. Advantageous refinements are specified in the subsequent subclaims.

• 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.

The device is used to connect a mast to a ground-mounted mast base and has the following:

• 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.

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.

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.

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.

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.

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 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 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 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 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 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 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 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 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 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 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 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 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 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 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 one configuration, the device comprises a mast that is connectable to the tilting plate.

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 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 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 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 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.

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.

• Ausführen einer ersten Drehbewegung des Masts um eine Längsachse des Masts, wobei zwischen Mast und Mastsockel ein Verbindungselement mit einer Drehführung angeordnet ist, die den Mast relativ zu dem Mastsockel führt,
• Ausführen einer ersten Kippbewegung des ·Masts um eine Kippachse, die von dem Verbindungselement zwischen Mast und Mastsockel vorgegeben wird,
• Ausführen von Wartungsarbeiten an dem Mast,
• Ausführen einer zweiten Kippbewegung, die der ersten Kippbewegung in entgegengesetzter Richtung entspricht,
• Ausführen einer zweiten Drehbewegung, die der ersten Drehbewegung in entgegengesetzter Richtung entspricht.

The procedure for maintaining a mast that is connected to a ground-mounted mast base has the following steps, to be carried out in the order given:

• Executing a first rotary movement of the mast about a longitudinal axis of the mast, a connecting element with a rotary guide being arranged between the mast and the mast base and guiding the mast relative to the mast base,
• Executing a first tilting movement of the mast about a tilt axis, which is predetermined by the connecting element between the mast and the mast base,
• Performing maintenance on the mast,
• Executing a second tilting movement which corresponds to the first tilting movement in the opposite direction,
• Executing a second rotary movement which corresponds to the first rotary movement in the opposite direction.

In the method it can be provided that a second fastening device of the connecting element, which prevents the rotary movement of the mast relative to the mast base, is released and then fixed again before the first rotary movement is carried out and / or released and then fixed again before the second rotary movement is carried out becomes.

In the method it can be provided that a first fastening device of the connecting element, which prevents the tilting movement of the mast relative to the mast base, is released before the first tilting movement is carried out and fixed again after the second tilting movement is carried out.

To explain the method, reference is made to the above explanations of the device. The method can in particular be carried out with the device described in detail, with the method mentioned connecting element of the device described above with base plate and tilting plate corresponds. Each of the. Features described in connection with the device can be used in the method, possibly independently of other features of the device.

Figure 1 shows a mast base adapter 10, which is an example of a mast base anchored to the ground or a part thereof. The mast base adapter 10 has a tubular section 12, which is designed for connection to a ramming tube or pile, and a substantially horizontally arranged base plate 14, which is connected to the tubular portion 12. The base plate 14 is square and has a circular opening 16 in its center and four through bores 18 at its four corners.

Above the mast base adapter 10, a base plate 20 is shown, which has a square basic shape and whose dimensions essentially correspond to the base plate 14. Through holes 22 are arranged at the four corners of the base plate 20, the arrangement of which corresponds to the through holes 18 in the base plate 14.

In addition, the base plate 20 has a circular opening 24 in the middle, which in a tubular section 26 protruding downward beyond the lower end of the base plate 20 (see here Figure 2 ) is trained. The tubular section 26 forms part of a rotary guide and engages in the circular opening 16 in the base plate 14.

The base plate 20 also has two ring segment-shaped grooves 28 arranged concentrically to the circular opening 24. The two grooves 28 are arranged opposite one another with respect to the circular opening 24 and each extend over an angular range of approximately 90 °. Each of the two grooves 28 has a step 30, which runs around half the depth of the groove around the entire ring segment shape. The grooves 28 form a further element of the rotation guide of the base plate 20.

Above the base plate 20 is shown a tilting plate 32 which, according to the first exemplary embodiment, is firmly connected to the mast 34, in particular by welding. The tilting plate 32 also has a square basic shape, the dimensions of which correspond to those of the base plate 20 and the base plate 14, In contrast to these, however, each has a recess 36 at its four corners, which is dimensioned such that the through bores 22 remain freely accessible at the corners of the base plate 20. The tilting plate 32 also has four through bores 38 which are arranged centrally on their longitudinal edges.

How the Figure 1 can be seen further, the tilting plate 32 and the base plate 20 are connected to one another in a hinge-like manner by means of a bolt 74. The bolt 74 defines a pivot axis about which the tilt plate 32 can be tilted relative to the base plate 20.

A first fastening device of the device Figure 1 comprises four threaded bolts 40 which can be screwed through the through holes 38 in the tilting plate 32 into correspondingly arranged threaded holes 42 in the base plate 20. In the case of threaded bolts 40 screwed into the threaded bores 42, the tilting plate 32 is fixed in a substantially parallel position relative to the base plate 20 and the mast 34 cannot be tilted.

Two threaded bolts 44 are inserted through the ring segment-shaped grooves 28 and screwed into two threaded bores 46 in the base plate 14. The two threaded bolts 44 each have a head, which rests on one of the steps 30 of one of the two grooves 28 and does not protrude above the base plate 20. In this way, the threaded bolts 44, which are guide elements of the rotary guide, fix the base plate 20 rotatably on the base plate 14.

Four further threaded bolts 48 are passed through the through bores 22 at the corners of the base plate 20 and the corresponding through bores 18 in the base plate 14 and are each screwed to a nut 50. she form the second fastening device with which the base plate 20 is fixed in a rotationally fixed manner to the base plate 14.

Also in the Figure 1 a hydraulic tilting device 52 is shown. It has a base plate 54 and a hydraulic cylinder 56. One end of the base plate 54 is provided for attachment to the base plate 14. The threaded bolts 48 of the second fastening device can be used for this purpose. The other end of the base plate 54, which is at a distance of, for example, one meter or more from the mast base adapter 10, is connected in an articulated manner to one end of the hydraulic cylinder 56. The other end of the hydraulic cylinder 56 can be articulated to the mast 34 at a distance from the tilt plate 32.

Figure 2 shows the base plate 20 Figure 1 in a perspective view obliquely from below. One recognizes the tubular section 26 of the rotary guide and the two ring segment-shaped grooves 28, in each of which a threaded bolt 44 is inserted for illustration.

Figure 3 shows the device Figure 1 after connection of base plate 20 and tilting plate 32 via the in Figure 3 Not shown bolt 74 and after screwing the two threaded bolts 44 into the threaded holes 46 in the base plate 14 of the mast base adapter 10. The first and second fastening devices are not yet attached, so that the base plate 20 is rotatable relative to the mast base adapter 10 and the mast 34 with the tilting plate 32 to the one in the Figure 3 Bolt 74 not shown defined pivot axis can be tilted around.

Figure 4 shows the device of the first embodiment with mast base adapter 10, base plate 20 and tilting plate 32 and attached mast 34 at a hint Track system 58 shown. It can be seen that the mast 34 is a signal mast with a side arm 60. In the operating position of the mast 34 shown, the lateral arm 60 is partially above the track system 58. In order to carry out maintenance work on the mast 34, the four threaded bolts 48 of the second fastening device 48 are first loosened and removed. Subsequently, the mast 34 is rotated by 90 ° about an axis of rotation determined by the rotation guide of the base plate 20, which corresponds to a longitudinal axis of the mast 34, so that the in the Figure 5 shown position results.

The four threaded bolts 48 of the second fastening device are then reinserted in order to prevent a further rotational movement. Then the tilting device 52 is mounted and the threaded bolts 40 of the first fastening device are loosened. The mast 34 can then be tilted around the pivot axis until the parts to be serviced are accessible from the ground. This tipping process is in the Figure 6 illustrated.

After completing the maintenance work, the mast is erected again as follows: First, with the aid of the tilting device 52, the mast 34 is erected again around the pivot axis until it is in the arrangement of the Figure 5 located. Then the threaded bolts 40 of the first fastening device are used to fix the tilting plate 32 to the base plate 20. The tilting device 52 can then be removed again.

Then the threaded bolts 48 of the second fastening device are loosened again and the mast 34 is returned to the in the Figure 4 shown rotary position rotated. Finally, the threaded bolts 48 of the second fastening device are reinserted.

Figure 7 shows a further embodiment in which a conventional mast 34 is used. The mast 34 has a base plate 64 which is screwed directly to a mast base when the mast 34 is used conventionally. In the invention, the base plate 64 is screwed to the tilt plate 32, with the aid of four threaded bolts 68, which are screwed through four through openings arranged at the corners of the base plate 64 into corresponding threaded holes 70 in the tilt plate 32.

The tilting plate 32, the base plate 20 and the mast base adapter 10 differ from the corresponding elements of the first exemplary embodiment only in the details highlighted below: The second fastening device for fixing the rotary movement between the base plate 20 and the mast base has four threaded bolts 48, which pass through openings on the Corners of the base plate 14 are passed and screwed into threaded holes made in the base plate 20 from below. The first fastening device has four threaded bolts 40 which are passed through through openings 66 formed on the four longitudinal edges of the base plate 64 and through four corresponding through openings 72 in the tilting plate 32 and screwed into threaded bores 76 in the base plate 20.
