Definitions

  • the invention relates to a device for lifting a mast and to the mast raised using such a device.
  • masts provided with this device. It applies more particularly but not exclusively to the masts of transmitting and / or provisional receiving antennas used for both military and civil purposes.
  • the mast is first laid down on the ground to be equipped with antennas and guying cables.
  • it is conventionally provided, on the one hand, with a base articulated around a horizontal axis passing through said base and with a shoe anchored in the ground and, on the other hand, at least one cable fixed near the head of the mast and on which from the base of this mast is exerted a traction.
  • the rope is substantially parallel to the mast and, therefore, to obtain sufficient torque when lifting, it is necessary to exert a very large pulling force.
  • this arm is generally provided at its lower end with a simple yoke which covers the mast or its base laterally and the yoke of its shoe anchored to the ground to benefit from the axis of articulation of this base when accompanying the mast during its tilting.
  • the mast Under the combined effect of the tensile force and the weight of the antennas associated with its top, the mast undergoes a deformation which can even, given its intensity, become permanent, or even lead to its rupture.
  • a result which the invention aims to obtain is a device of the aforementioned type, which facilitates the lifting of a mast by preventing any permanent deformation liable to be imparted to it by the load which it supports.
  • Another result which the invention aims to obtain is a device of the aforementioned type to which it is simple to fix the cables connected to the mast and the winch.
  • the subject of the invention is a lifting device of the aforementioned type, in particular characterized in that it comprises means for folding the lever around an axis which is orthogonal to the axis of articulation of the base. of the said lever.
  • a mast 1 is first of all lying on the ground to be equipped with its antenna 3 and to be associated with the articulation axis 4 of a yoke 5 carried by a shoe 6 anchored on the ground 2.
  • At least one cable 7, 8 which, by one end 9, 10, is fixed at a certain distance from the base of the mast and which, by its other end 11, 12, is fixed in head 13 of a lever arm 14 perpendicular to the axis of the mast and the base of which has a clevis 15 laterally covering the mast to articulate with it around the axis 4 of the clevis 5 of the shoe 6 but to be immobilized relative to the mast.
  • the lever is not operated by hand but by a traction means such as a winch 16 which, with its cable 17 is interposed between the head 13 of the lever 14 and a point 18 for anchoring to the ground located in the extension axial of the mast and the side of its base.
  • the actuation of the winch 16 then calls the lever which, by the cables 7, 8, gradually raises the mast.
  • the latter is provided with means 19, 20, 21 for folding the lever 14 around an axis 20 which is orthogonal to the axis 4 of articulation of the base of the said lever 14.
  • the arm 23 can, during assembly, fold towards the ground, laterally to the mast 1 which facilitates access to the head of the lever.
  • this fixing will be done with a slight tension.
  • the orthogonal axis 20 is located at a sufficient distance from the axis 4 of articulation on the shoe 6. Therefore, before lifting the mast, the straightening of the lever 14 moves its head away from its base, which will stretch the cable connecting the head of the mast and will automatically accentuate or cause the pre-bending of the mast ( Figure 6).
