Definitions

  • the present invention relates to a self-lifting telescopic mast mounted on a trailer and intended in particular, but not exclusively, for the establishment of temporary civil or military radio links.
  • Self-lifting masts carried on a self-towing trailer are known, in particular from FR-A-2 422 792. They consist of elements of decreasing section from bottom to top whose relative movement is controlled by cables, a cylinder being disposed inside the lower element, so as to raise the second element, this elevation of the second element resulting in the deployment of the pylon under the action of the cables passing over pulleys.
  • the lower element rests on the ground and a triangulation ensures the stability of the deployed pylon. This triangulation requires the installation of shrouds which requires a long installation time often incompatible with the needs of the service.
  • Other pylons of this type are described in patents FR-A-1 357 031, FR-A-1 545 379 and US-A-3 047 107.
  • the object of the present invention is to remedy these drawbacks and to make it possible to obtain a compact folded structure which can be erected quickly and without tools by a single man, in a reduced time compared to that required by the installation of the self-propelled prior art elevators.
  • the self-lifting telescopic mast mounted on a self-towing trailer comprising telescopic elements of decreasing section from bottom to top, a tilting cylinder of the lower element, and at least one lifting cylinder inside the basic element, is characterized in that it comprises semi-automatic spikes, pivotally mounted on axes carried by the trailer.
  • the struts provide stability and level of the mast, which in some cases achieves sufficient triangulation on the ground.
  • the pylon works completely in console and the pylon foot no longer touches the ground.
  • the bracons whose weight can be for example 200 kg, require for their positioning, an effort of approximately 30 kg which can be provided by a single man.
  • the double tilting cylinder works in thrust.
  • the telescopic elements are elements with triangular cross-section with double members.
  • the actual erection time of the pylon at 30 meters can be, for example, 1.5 minutes, all of the positioning operations lasting approximately ten minutes.
  • the trailer designated by the reference 1 carries a telescopic pylon 2 consisting of elements 2a, 2b, 2c, 2d, 2e, 2f.
  • the mast supports for example a parabolic antenna 3, the head load can be arbitrary with a limit of 350 kgs, for example.
  • the element 2a rests on the trailer 1. It has a frame 4 carried by two wheels 5. It rests on the ground, on the one hand by a shoe 6 and on the other hand by two struts 7 in triangulated profile. , pivotally mounted each around an axis 8 inclined relative to the vertical. Thus, after deployment, they automatically come into contact with the ground. The end of the struts 7 rests on the ground by pads 9.
  • each of the coils comprises, coiled, a guy 11 whose one end is connected to the upper part of the upper element 2f.
  • a third coil 10 is mounted on the boom of the chassis 4 of the trailer. After deployment of the bracons, these form, with the arrow, a substantially equilateral triangle.
  • the mast does not rest on the ground, but is carried by the chassis 4 of the trailer which, itself, rests on the ground by the pad 6 and by the pads 9 (including one only appears in Figure 1).
  • Guy lines 12 remain at a fixed position on the mast, whether it is unfolded or folded, without any tools for their tension, this tension being adjustable by hand by tensioners 13.
  • the three automatic reels 10 can be detached from the struts and from the trailer support to be fixed at a distance of approximately 15 meters from the trailer. At this time, mast stability is ensured for winds of up to 160 km / hour. It was necessary, in the known pylons, to use a much higher number of coils, for example 13, to obtain the same stability.
  • Figure 2 is shown the telescopic mast in the folded and tilted position on the trailer 1.
  • shrouds 11 have been folded over the reels 10, the arrangement of the pulleys 14 allowing keep the shrouds in their throats, without having to fix them.
  • the lower element 2a of the pylon is pivotally mounted about an axis 15, this pivoting being obtained by action on two hydraulic cylinders 16 of which only one appears in the figure. Said jacks work in thrust whereas, originally, the lower element was pulled to make it tilt.
  • FIG. 4 represents a detailed view of the mast in the erection position, and it can be seen in this figure, that the elements of the mast 2 are constituted by lattice beams in order to reduce the wind resistance and the weight, these beams having a triangular section. In each corner of the section are arranged two parallel uprights 17, 18, serving as a guide for the upper element, so that each of the elements is guided over its entire height, rigorously, which avoids the possibility of overlapping during erection or during the redeployment of the mast.
  • the operating mode of a mast is as follows. Firstly, the antenna 3 and the aerials are mounted, before the assembly tilts, that is to say on the ground. Then, the opening of the semi-automatic bracons ensures the leveling and the stability of the whole. The arms are then locked and tensioned. The tilting of the lower element 2a by the preferably hydraulic jacks 16, controlled from a station located either in the towing vehicle or on the trailer. The mast can then be raised by the lifting cylinder (not shown) and the guy lines 11 remain either attached to the trailer and to the struts, or are moved away from the latter by means of the coils 10 in the event of bad weather. The head load can reach 350 kg and the set up is very quick and for example, one man can erect and stay the mast in about 10 minutes.
