Definitions

  • the technical sector of the present invention is that of devices intended to improve the buoyancy of floating assemblies, more particularly applied to crossing machines for rapid or non-rapid implementation, to tanks, to barges, having end elements or access ramps used for loading and unloading heavy loads.
  • the present invention aims to eliminate the aforementioned drawbacks, by proposing a device for improving the buoyancy of the end elements making it possible to facilitate the loading and unloading of heavy loads such as armored vehicles or the like, by reducing as much as possible the sinking of the main floats and the loaded end element, regardless of the position of the shore relative to the body of water.
  • the invention also aims to involve in its entirety, the additional float under the end element, in the buoyancy of the floating assembly by permanently maintaining the entire lower surface of the float in contact with the plane of water, regardless of the position of the end element (positive or negative site).
  • the invention relates to a disposi tif to improve the buoyancy of a floating assembly by means of the end element articulated in the vertical longitudinal plane of the floating assembly, of the type comprising an auxiliary float, characterized in that it comprises means articulation of the float relative to the end element in the same vertical plane.
  • the articulation means can consist of an articulation axis located at the lower end of the element and at the upper end of the float and by at least one hydraulic cylinder articulated at its two ends on the element and on the float.
  • the hydraulic cylinder is fixed in rotation by one of its ends to the float, the other end of the cylinder being fixed in the same way to at least two rods, themselves also fixed in rotation, one with an end element and the other with a float.
  • a floating assembly 9 having an end element 4 to which is attached an auxiliary float l articulated at 3 with the lower part of this end element 4.
  • the float l is made movable relative to this element by at least one hydraulic cylinder 5.
  • the elements are articulated in the vertical longitudinal plane of the floating assembly.
  • the end element 4 is on the one hand, fixed in rotation at 8 with the floating assembly constituting a support and on the other hand posed and adjusted on a bank markedly raised relative to the body of water.
  • the hydraulic cylinder 5 being fixed in rotation by one of its ends to the float 1, the other end of the cylinder is advantageously fixed in the same way to at least two rods 6.
  • the rods are also fixed in rotation to their corresponding support , one in l0 to the element end and the other in ll to the float.
  • a servo system 7 linked to the angular position of the end element and intended to control the hydraulic cylinder 5 can be fixed by any means to the body of the cylinder, or elsewhere.
  • the invention allows the use of a flexible or rigid auxiliary float.
  • a rigid support 2 is fixed by any means to the upper part of the float l making it possible, in the case of a flexible auxiliary float, to ensure better rotational fixing, on the rigid support, of one end of the hydraulic cylinder 5 and a link 6.
  • the articulation means can be partially or totally housed or inscribed in the lower part of the end element 4.
  • the hydraulic cylinder 5 controlled by the servo system 7 allows, by means of articulation, to keep the entire lower surface of the auxiliary float l in contact with water while keeping the latter in a horizontal position. Therefore, the depression of the end element and, consequently, of the floating assembly is considerably limited by a significant Archimedes thrust exerted on the auxiliary float. This gives maximum buoyancy of the floating assembly.
  • the invention as described above remains applicable in the case of a negative inclination of the end element relative to the floating assembly, the upper part of which is then above the level of the shore, the float remains attached to the underside of the end element in this case (the negative position does not activate the servo system).
