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.
