Definitions

  • the invention relates to a mobile antenna system with a telescopic mast, which is arranged foldable on a base frame with a base area corresponding to that of a container, the base frame having laterally fold-out cantilevers which are provided at their outer ends with support cylinders and base plates which are supported on the base .
  • Such antenna systems have mobile carriers, mostly trucks. They can be set up with these or separately. Because of their height, their telescopic masts have to be supported laterally and anchored, for which purpose they are assigned pivotable brackets which are designed as telescopic support legs according to DE-OS 32 01 067. These known antenna systems can only carry small weights, especially in the area of the top of the mast, and are therefore of limited use. In addition, the telescopic design of the support legs means that there is a high manufacturing outlay and thus correspondingly high investment costs. The same applies in principle to the antenna mast known from DE-OS 17 59 192.3-25, which is supported accordingly via a trestle of support legs and, in addition, via a support reaching down to the ground in order to achieve greater stability. Here too, as mentioned, only limited loads can be attached to the mast.
  • Antenna systems are also known from the prospectus of the applicant W 477 f / sp. 285,500 H. According to Figs. 9738 and 44328, they have laterally pivotable booms that have vertical support cylinders at the ends, against which the booms can be braced on the ground. Movable operating bars are attached to the chassis of the carrier vehicle or to the base frame of the mast.
  • the disadvantage of this known system is that it is a must have certain ground clearance because the cantilevers are designed as sloping beams or structures on which the vertical support cylinders are arranged at the ends. This means that such a system cannot be moved in the manner of a container by such carrier vehicles, but rather must be tailored to such a vehicle in order to ensure the necessary ground clearance in any case. Partial dismantling is even necessary for transport by rail or ship.
  • Another antenna system with a telescopic mast that can be supported by side arms can be found in the same brochure (51243, 51238).
  • This system has a base frame on which the swing-out booms are articulated via an inclined axis.
  • the arms which have the extendable support feet at the ends up to the height of the base frame, so that overall favorable dimensions result.
  • the known antenna system is only intended for relatively light units and is equipped with support feet and brackets which can be extended by hand. With larger systems, the boom ends would protrude very far or could not be folded in unhindered. In both systems, the mast is not braced, which means that e.g. Enable directional antennas.
  • a stiff four-link system is known, but used there as a support device for excavators and cranes.
  • This four-bar system cannot be equated with articulated struts, especially since it is much more complex to build and does not save sufficient space even when it is closed.
  • a support bracket for construction machinery is known from DE-GM 76 39 621, in which a type of support cylinder can be pivoted from the vertical into the boom itself.
  • the boom is designed as a telescopic beam and the support cylinder itself can be pivoted about an articulation, so that overall a relatively complex, but not seen from the support cylinder, stable design results which requires a complex telescopic boom.
  • Both known systems have a very small and therefore unsatisfactory projection for antenna systems.
  • the invention has for its object to provide an antenna system with container-like dimensions, which is inexpensive to transport, easy to set up and dismantle and has great stability thanks to wide cantilever arms, which are designed so that the antenna system even in extremely uneven terrain is to be set up.
  • the front and rear booms are designed as a two-part structure
  • the outer section, which supports the support cylinder can be pivoted via a horizontally arranged joint relative to the inner section connected to the base frame and has a rope pulley via which a tension cable which can be actuated by a cable winch assigned to the supporting structure is guided to the mast head
  • both sections of the front and rear brackets are each connected as a whole to the base frame via an articulated strut, each of the articulated struts being able to be folded in and out again via an associated hydraulic cylinder.
  • Such an antenna system can therefore be transported in a container-like manner because the laterally extendable or swing-out booms can be folded up and raised from a stable lattice structure, for example, in such a way that they can be arranged above the base frame or above the loading area of the carrier vehicle even when retracted.
  • the laterally extendable or swing-out booms can be folded up and raised from a stable lattice structure, for example, in such a way that they can be arranged above the base frame or above the loading area of the carrier vehicle even when retracted.
  • the tensioning cable since it is guided on the foldable section of the jib via a cable pulley and thus causes this section to swivel in.
  • the boom itself is hydraulically swung in and out using a kink strut.
  • Such an antenna system apart from the extension of the mast, can itself be installed in a very short time so that a correspondingly high mast can then be extended without the risk that it is endangered by the wind or other loads and above all, that it can be safely used for directional radio operations due to the guying.
  • the antenna system according to the application thus has pivotable cantilevers which can be pivoted so high and so that the entire retracted system can be easily transported or transported on a carrier vehicle in terms of containers.
  • these brackets enable a secure stand even when the floor is extremely uneven and the antenna is aligned securely.
  • the front and rear arms connected to the base frame are associated with control bars which have links with which the control bars can be pivoted with respect to the base frame.
  • the articulated struts and / or in each case the section of the boom are expediently connected to the pivotable operating webs or the links which guide them via coupling rods. It is thus advantageously possible to fold down the operating webs that are important for assembly and disassembly at the same time as the booms are swung out, or to pull them out in the case of another design, which can then be used by the operating personnel during the further extension and stabilization of the booms.
  • operating bars are used primarily to actuate the waveguide drums, the push rod locks, the antenna assembly and also in emergency operation they are required. Overall, it is possible in this way to provide a relatively simple system of operating bars on the sides of the carrier vehicle, especially since the operating bars can be designed as such in an aluminum hollow profile construction. Since they can be swiveled out simply and securely and can also be swiveled in again when the booms are retracted, they can perform further functions, the invention providing for this purpose that they serve to protect the attachments, in particular the waveguide, during transport.
  • a particularly expedient embodiment of the invention provides that the section of the front and rear brackets supporting the support cylinder is formed to form a grid triangle consisting of a base strut and support struts, on the base strut of which the support cylinder is attached and in the node formed by the support struts the horizontally arranged joint and the rope pulley is arranged at the junction point opposite the jib foot.
  • the hinge is attached so that the folding of the section supporting the support cylinder is also ensured due to its own weight, for which purpose it is provided, as explained, at the corresponding node, namely at the node of the lattice triangle formed by the support struts.
  • the section supporting the support cylinder must be fixable relative to the section pivotably attached to the base frame.
  • This bar is pulled out when the grid triangle is folded down and can then be locked in the end position so that the necessary supporting forces can be transferred without problems.
  • the bar is advantageously locked in that the segment connected to the base frame is assigned a segment lock which can be pivoted via a spindle in front of the beam, the bar having interlocking bolts and hooks at the free end and the segment in the locked state.
  • An embodiment of the invention which is advantageous for protecting the rope as such provides that the rope winch assigned to the base frame is designed as a hydraulically driven friction winch. Since the ropes perform an extremely important function due to the forces to be taken over by them, they are secured accordingly, especially by applying an appropriate coating. This coating is retained because the friction winch works gently.
  • the guy rope pretensioning force of all friction winches is jointly monitored and hydraulically controlled. During operation of the mast or the associated antenna system, care is taken to ensure that the guy ropes are each subjected to a uniform tightening force or pretensioning force. Since all four friction winches are connected at the same time and apply the same pressure, a uniform protection of the mast is guaranteed without additional measures being necessary.
  • the folding of the section supporting the support cylinder which is designed according to the invention as a lattice triangle, is achieved solely by the dead weight, whereby the dead weight can be increased even further by providing consoles for the octagonal or round-shaped base plates on the side of the support cylinder, the base plates being above
  • This also gives you the option of detaching the base plates from the brackets after unfolding the lattice triangle and then quickly connecting them to the support cylinder using the quick-release fasteners, in order to ensure even support even on uneven floors.
  • the invention is characterized in particular by the fact that an antenna system with a supporting mast and base frame that is advantageously transportable is created, which can be applied to the chassis or the loading area of the carrier vehicle without difficulty, because the outriggers assigned to the base frame can be folded to container dimensions.
  • the outriggers important for supporting the mast are folded in so that they do not represent any hindrance during transport. When they are folded in, they are operated by the guy rope and brought into the transport position without the need for additional intervention by the operating teams. At the same time, the operating bridges are also folded in, which can then also be optimally used to secure the machine parts behind them. Conversely, the booms are swung out via the hydraulic cylinders assigned to the articulated struts.
  • the swung-in section of the jib also swings out at the same time, so that it can then be locked in the swung-out position via the beam.
  • the support cylinder assigned to each boom is extended in order to secure the entire system at the same time.
  • the associated operating dock is then also swung out at the same time, which is then available at an early stage for inspecting the system and thus for carrying out assembly work.
  • Fig. 1 shows a mobile antenna system with extended mast (1), antennas (2) are attached to the top.
  • the support mast (1) is located on a carrier vehicle (3), on the chassis (4) or loading area (5) of which the entire support mast (1) can be stored with the appropriate guying during transport.
  • the carrier vehicle (3) usually remains with the antenna system. Since it has container dimensions, it can be transported on the railroad or on ships without any problems and then without a carrier vehicle (3).
  • the tensioning cables (9) arranged and tensioned between the mast head (6) and the front brackets (7) and the rear brackets (8) and the correspondingly swung out front and rear brackets are used (7, 8) itself.
  • the tension cables (9) are over Rope pulleys (10), which are assigned to the arms (7, 8), as will be explained further below.
  • the arms (7, 8) are pivotally mounted on the base frame (11) and consist of two sections (12, 13).
  • the inner section (12) seen from the base frame (11) is pivotably mounted on the base frame (11), while the outer section (13) carries the support cylinder (14) with the base plate (15) and is pivotable with the section (12). connected is.
  • Support cylinder (14) and base plate (15) have corresponding connecting means so that the two parts for supporting the mobile antenna system can be quickly connected to one another.
  • Fig. 2 shows a plan view of the base frame (11), on which the pivotably arranged or executed arms (7, 8) are arranged.
  • the support mast (1) is shown in the extended position.
  • the tensioning ropes (9) are brought together from brackets (7, 8) on the mast (1) and more precisely on the mast head (6).
  • Fig. 3 shows the two sections (12, 13) in the swung-in and Fig. 4 in the swung-out state.
  • the section (13) of a base strut and support strut having grid triangle (30) is formed, on the base strut (31) of the support cylinder (14) is arranged.
  • the node (32) of the lattice triangle (30) formed by the support struts carries the horizontal joint (33) to pivot around the lattice triangle (30) and thus the section (13) from the transport position according to FIG. 3 into the working position according to FIG. 4 to be able to, this is due to the weight of the section (13).
  • the cable pulley (10) is arranged, which when actuated via the cable winch for the pivoting back of the lattice triangle (30) and thus the Section (13) in the transport position shown in Fig. 3 takes care.
  • brackets (16) are attached, on which the base plate (15), as shown in FIG. 3, can be clamped in order to then use the corresponding quick-release fasteners when the section (13) in accordance with FIG. 4 is extended to be connected to the boom foot (17).
  • Fig. 4 the boom is shown with the section (13) swung out.
  • This pivoted-out position is ensured in that a bar (35) is pivotally arranged on the short strut of the lattice triangle (30) and is simultaneously guided in the section (12).
  • a segment lock (37) is pushed in front of the bar (35) via a spindle (36), so that, as shown in FIG. 5 can be seen, is optimally secured.
  • Beams (35) and section (12) have a bolt (38) or a hook (39) to enable the connection secured by the segment lock (37).
  • a fuse can be secured via the bolt (38) and a corresponding pawl on the section (12) pivoted-in state can be achieved.
  • the bar (35) pivotally connected to the grid triangle is then advantageously secured in the transport position even if the tensioning cable fails.
  • the cable winch is designed as a friction winch (41), with the return cable (42) and the tensioning cable (9) ensuring that when the tensioning cable (9) is retracted, a swiveling back of the cable is carried out at the same time Part (13) takes place if the segment lock (37) has previously been pivoted or turned away via the spindle (36).
  • FIG. 6 and 7 show the bracing and securing of the brackets (7, 8) already apparent from FIG. 2 by means of the buckling struts (19, 24).
  • the buckling strut (19) is connected to the operating web (21) via the coupling rod (22), so as to achieve the pivoting of the operating web (21), which itself is guided via the handlebar (23).
  • the operating web (29) is in turn connected to the base frame (11) via the handlebars (27), whereby a uniform pivoting of the operating web (29), which is covered with a safety light curtain (28), is achieved, with a simultaneous connection of the operating web (29) via a coupling rod (26) with the section (12).
  • the articulated struts (19, 24) have a connection to the respective hydraulic cylinder (20, 25) in the articulated joints (43, 44).
  • the individual operating webs (21, 29) are swung out simultaneously via the articulated struts (19, 24) so that they can be walked on. Conversely, as when swinging the boom (7, 8), the individual operating webs (21, 29) are also lifted and swung back at the same time via the articulated struts (19, 24) or the handlebars (22, 26) when the boom is swung in.
  • the optimal container width can be maintained because the folded arms (7, 8) are pivoted in front of the service bars (21, 29).
  • Fig. 8 shows again the transport vehicle (3) in a side view, although here the entire mast (1) and the antennas (2) have been moved into the transport position. It is clear here that the individual booms (7, 8) with their two sections (12, 13) are each raised or retracted so that they ensure the container dimensions. The base plates (15) are clamped and supported on the support cylinders (14) via the brackets (16) so cheaply that they fit into the entire container size. This results in an overall very compact design of such a mobile antenna system with a loaded mast (1).
