Definitions
- the invention relates to a method for extending an overhead line mast, in particular a lattice mast with a square cross-section according to the preamble of claim 1 and an apparatus for performing the method.
- a method for the erection of such overhead line masts is from the BE-A-645 734, in which after determining the place of installation Prefabricated mast parts are successively assembled with each other by a mast section is raised by means of a lifting device, inserted a new mast part below and is connected to the mast section and this process is repeated until the intended mast height has been reached.
- an operating Transmission tower without interruption of operation that is, without switching off the high voltage is extended, with a lifting device on the transmission tower to be extended placed and in at least two planes spaced from each other is firmly connected to the mast.
- the lifting device initially serves to to support the mast against lateral deflection.
- the mast is complete the conductor cables suspended from the trusses are separated from its mast base and raised by means of the lifting device connected to the mast until it has reached the desired height.
- Mast and mast foot inserted and filled with a prepared mast part filling the gap the raised mast and the mast base are also firmly connected, similar to building a stick. If the inserted mast part is firmly connected on all sides, the connection is made the lifting device with the mast released and the lifting device from the mast away.
- a lifting device of the type mentioned above for According to the invention the method is carried out by Features of claim 3 characterized.
- Such Lifting device has supports that move evenly around the mast is distributed and with each other and with the Mast are firmly but releasably connected.
- the supports are telescopically adjustable, preferably by means of hydraulic loading.
- the lifting means are hydraulically loaded, whereby according to a preferred embodiment of the invention, the lifting means are designed as a hydraulic grip.
- cables can be integrated in the supports, which serve to secure the mast and so to its Ensure stability for the duration of the renovation.
- the main advantage of the invention results from that the above-mentioned adjustment of the ground clearance of the overhead lines to the required height for those in operation Overhead lines can be made without the electricity must be parked in the overhead lines.
- the overhead lines over isolators are connected to the support arms of the support masts with the stability of the masts during the extension procedure contribute.
- FIG. 1 shows an overhead line mast 10 with support arms 12, 14 and conductor cables 16, 17, 18 suspended thereon in a side view shown, which is held by a lifting device 20 which consists of supports 22 arranged on each corner post with integrated lifting devices, not shown here is formed.
- a lifting device 20 which consists of supports 22 arranged on each corner post with integrated lifting devices, not shown here is formed.
- FIG 1 is a common Overhead line mast 10 is intended to illustrate how using the lifting device 20 according to the invention there is the possibility of such a mast 10 so far to raise that, as shown in Figure 2, an extension piece 30 without difficulty between the mast base 11 and the raised overhead line pylon 10 are inserted can.
- the supports 22 of the lifting device 20 are in three places by means of trusses 24, 26, 28 firmly with each other and with connected to the mast 10 or to the mast foot 11.
- the lifting device 20 according to the purpose Implementation of the method according to the invention is provided that first the lifting device, d. H. the pillars 22 to be placed on the corner posts of the mast 10 and there in each case by means of the mentioned cross members 24, 26, 28 are firmly connected to each other and to the mast 10. Subsequently, the mast 10 in the area of the mast base 11 separated from this and by means of the lifting device 20 slowly raised until it reaches the one you want Height, d. H. the intended minimum distance between the Ropes 16, 17, 18 and the bottom reached. In the resulting gap between mast base 11 and the mast 10 becomes a correspondingly prepared mast extension part 30 used and with the mast 10 and with the Mast foot 11 firmly connected, as is the case with normal mast construction is common. Then the trusses 24, 26, 28 removed as well as the supports 22 of the lifting device 20.
