[0067] FIG. 1 shows a fixing device 1 according to the invention for fixing eight solar collectors 2 to a pylon 4. The illustrated embodiment has two collector pedestals 5 to each of which four solar collectors are fixed at the site of installation 3 at the pylon 4. Further, there is shown the reversing device 6 that is fixed to the pylon 4 above the site of installation 3. Below the site of installation 3 there is arranged the lift body 8 that is connected to the winch device 7 at the base of the pylon 22 via the hauling element 9. In this example, the hauling element 9 is a cable. Here, the hauling element 9 or cable, respectively, is guided over the reversing device 6. Further, the length of the hauling element 9 is reduced.

[0068] The fixing device 1 shown in FIG. 2 corresponds to fixing device 1 illustrated in FIG. 1, wherein the hauling element 9 or cable, respectively, guided over the reversing device 6 is not yet shortened. This means that the lift body 8 that is connected to the winch device 7 via the hauling element guided over the reversing device 6 is in a position below the site of installation 3. The two collector pedestals 5 are arranged above the lift body so that they rest on the lift body 8 due to gravity G.

[0069] FIG. 3 is a view of the fixing device 1 that is partially mounted to the pylon. The reversing device 6 is fixed to the pylon 4 with the reverse body 12 above the site of installation 3. As the means for fixing the reversing device 6 to the pylon 4 there is shown a ladder 21 that is leaned against the pylon 4 so that a mechanic (not shown) can climb the pylon 4 to fix the reversing device 6 to the pylon 4. FIG. 3 further shows how the hauling element 9 or cable, respectively, is guided over the reversing device 6 by the winch device 7.

[0070] A detailed illustration of the reversing device 6 is shown in FIG. 4. The reversing device 6 fixed to the pylon 4 has two reverse bodies 12 that are realized as pulley 13. With the help of the two pulleys 13 the hauling element 9 is guided over the reversing device 6, wherein the pulleys minimize the friction between the reversing device 6 and the hauling element 9 or the cable, respectively, and effectively prevent the hauling element 9 or cable, respectively, from coming off or catching.

[0071] FIG. 5 is a detail view of the fixing device 1 in which there is illustrated the winch device 7 and its fixation to the pylon in the form of pylon clamps 18. In the embodiment shown, the winch device 7 with a total of four first pylon clamps 18 is fixed to the pylon 4 above the base of the pylon 22 such that two first pylon clamps each are opposite. The opposite first pylon clamps 18 are connected to two first threaded joints 23 such that the distance between the opposite first pylon clamps 18 substantially orthogonal to the pylon 4 can be reduced and thus, the winch device 7 can be clamped to the pylon 4 by actuating the first threaded joint 23. It is further shown, that the first end 10 of the hauling element 9 or cable, respectively, is fixed to the winch device, whereas the second end 11 of the hauling element 9 or cable, respectively, is still free.

[0072] FIG. 6 shows the fixing device 1 that is partially mounted to the pylon 4, wherein in contrast to FIG. 3 already the lift body 8 is displaceably fixed to the pylon. The second end 11 of the hauling element 9 or cable, respectively, is fixed to the lift body 8. The first end 10 of the hauling element 9 or cable, respectively, guided over the reversing device 6 is fixed to the winch device 7. The winch device 7 is fixed to the pylon 4 in the vicinity of the base of the pylon 22. Since the hauling element 9 or cable, respectively, is not yet shortened, the lift body 8 is in a position below the site of installation 3 of the at least one solar collector 2.

[0073] FIG. 7 is a detail view of the winch device 7 illustrated in FIG. 6 as well as the lift body 8. As already illustrated in FIG. 5 it can be seen that the winch device 7 is fixed to the pylon 4 by means of four first pylon clamps 18. Here, two first pylon clamps 18 each are connected to a threaded joint 23 such that the distance of the pylon clamps upon actuating the threaded joint orthogonal to the pylon 4 is reduced and thus, the pylon 4 is clamped between the first pylon clamps 18.

[0074] Further, it can be seen that the lift body 8 has a guiding means 14 that is built up of four guiding means parts of which in FIG. 7 there can be seen a first guiding means part 16 as well as a second guiding means part 17. Of the total of eight pulleys 15 of the guiding means 14 that abut on the pylon, four can be seen in FIG. 7. The eight pulleys 15 abutting on the pylon are arranged at the guiding means 14 around the pylon in two planes lying above each other with four pulleys 15 each that abut on the pylon. Here, the four pulleys 15 in one plane that abut on the pylon are offset to each other by an angle of 90. The rotational axis of each of the pulleys 15 abutting on the pylon is connected to the guiding means 14 by a second threaded joint 24 each. Here, the second threaded joint 24 is passed through an elongated hole 27 such that the second threaded joint 24 together with the respective rotational axis can be displaced perpendicularly toward the pylon 4. As a result, thus each of the pulleys 15 abutting on the pylon can be displaced perpendicularly to the pylon 4. Further, it can be seen in FIG. 7 that the hauling element 9 with a first end 10 is fixed to the winch 7 and with the second end to the lift body 8.

[0075] In a not-shown example the lift body also has a guiding means that is built up of a first guiding means part and a second guiding means part. However, in contrast to the embodiment shown in FIG. 7 the first guiding means part and the second guiding means part can be adjusted in their distance to each other by two fourth threaded joints so that the abutting pulleys of the guiding means abut on the pylon. In analogy to the embodiment illustrated in FIG. 7 the guiding means of the not-shown example preferably has eight pulleys abutting on the pylon. As also shown in FIG. 7, in the not-shown example the hauling element with a first end is fixed to the winch and with the second end to the lift body.

[0076] FIG. 8 shows a detail view of the fixing device 1. Here, the winch device 7 is connected to the lift body 8 via the hauling element 9 or cable, respectively. The winch device 7 is fixed to the pylon 4 in the vicinity of the base of the pylon 22, whereas the lift body 8 is moveably arranged at the pylon 4. The two collector pedestals 5 with the four solar collectors 2 each are arranged above the lift body 8 such that the collector pedestals 5 rest on the lift body 8 due to gravity G. Four solar collectors 2 each are connected to one collector pedestal 5 by two clamp connections 19. It can be seen that the solar collectors 2 are inclined over the vertical so that the solar collectors are oriented toward the sun. It is further seen in FIG. 8 that the hauling element 9 or cable, respectively, still is not shortened.

[0077] In FIG. 9 there is shown a fixing device in which the hauling element 9 or cable passed by the winch device 7 over the reversing device 6 to the lift body 8 has been shortened such that the lift body 8 has moved along the pylon 4 toward the reversing element 6. Thereby, the two collector pedestals 5 having the eight solar collectors 2 present thereon and being arranged above the lift body 8 were lifted toward the site of installation 3 of the solar collectors 2 at the pylon 4 against the gravity G. In order to fix the eight solar collectors 2 to the pylon 4, further as a means there is shown a ladder 21 with which a mechanic (not shown) can climb the pylon 4.

[0078] FIG. 10 is a detail view of the fixing device 1 illustrated in FIG. 9. The two collector pedestals 5 are clamped to the pylon 4 with four second pylon clamps 26. Here, two third threaded joints 25 each connect two second pylon clamps 26. By actuating the third threaded joints 25 the distance between the second pylon clamps 26 orthogonal to the pylon 4 can be reduced and thus, the pylon 4 can be clamped between the second pylon clamps 26. Further, two of the four clamp connections 19 can be seen with which the total of eight solar collectors 2 are clamped to the two collector pedestals 5. A ladder 21 is shown as a means with which one can climb the pylon 4 to tighten the third threaded joints 25 of the second pylon clamps 26 and to fix the solar collectors 2 to the pylon 4.

[0079] In FIG. 11 there is illustrated the fixing device 1 in which two collector pedestals 5 are fixed with eight solar collectors 2 in total to the pylon 4. In FIG. 11, the reversing device, the lift body, the hauling element, and the winch device are not shown. These were demounted from the pylon 4 to protect the solar collectors 2 from unauthorized removal. Further, symbolically an electrical consumer 20 is shown at the base 22 of the pylon that can be supplied with electric power via the solar collectors 2.
