Definitions

  • the present invention relates to an installation for horizontally transporting a boat on firm, dry ground. Such an installation is integrated into a more complex installation making it possible to transport a boat from water to firm ground and vice versa.
  • Some ship dry or water installations include a lift to lift each ship from the water to ground level.
  • Such an elevator includes a platform raised by winches. The boat rests on the platform during the transport of the water up to ground level, that is to say to the position where it emerges. Each boat must then be moved horizontally from the elevator to a garage position.
  • the horizontal transport of a ship is generally carried out by wheeled carts placed under the keel of this ship.
  • This mode of transport lacks flexibility to absorb the irregularities of the ground and to distribute the load of the ship.
  • these trolleys only serve one direction, which limits the number of boats that can be parked on a given surface.
  • British patent 1,016,785 describes a trolley transport installation making it possible to move the boat in any horizontal direction.
  • the boat rests on a line of beams arranged perpendicular to its longitudinal axis. Each beam rests at its ends on two carriages.
  • the different carriages are stored in two rows and each section of the boat is supported, via the beam and the carriages, which ensures good load distribution.
  • the support of each beam on each carriage is effected by means of a double-acting hydraulic cylinder.
  • the jacks allow, when the beams are supported on the ground, to lift the carriages above the rails and thus to rotate them from one track to another track. Changes of direction can therefore be made.
  • the cylinders allow above all to support elastically and isostatically the boat with respect to the ground.
  • the cylinders supporting the beams are divided into three groups. All the cylinders in the same group are connected together so that the reactions of these cylinders are equal.
  • a first group comprises the jacks associated with a fraction of the carriages aligned on one of the tracks.
  • the second group includes the cylinders associated with a fraction of the carriages aligned on the other track.
  • the third group includes all of the jacks mounted on the support carriages to a group of support beams located at the end of the row of beams.
  • Each group of cylinders is equivalent to a fictitious support at the center of the geometric figure that they define.
  • the three resulting from the three groups of cylinders are located at the vertices of an isosceles triangle whose main height is parallel to the longitudinal axis of the boat.
  • the boat only rests on two rows of parallel tins so that the forces on these tins are balanced.
  • British patent 1 229 261 describes a transport installation in which the boat is supported by two rows of support beams mounted on running gear. The boat is supported on each support beam by a single support and is thus supported by two parallel rows of supports. It is not possible to provide a higher number of beams and supports if we want the reactions of the supports to be balanced.
  • the subject of the present invention is an installation intended to transport a large tonnage ship by supporting it, isostatically, by at least three rows of tins parallel to the longitudinal axis of the ship.
  • Balancing of the forces on the different tins located under a section is ensured.
  • the lateral tins ensuring the stability of the vessel, when launching or leaving the water or during movement, are kept in permanent contact against the hull of the vessel.
  • the coupling or the hitching is carried out automatically.
  • this installation is characterized in that the support beams are arranged in at least three rows parallel to the longitudinal axis of the boat and offset from each other by so that a so-called lateral queue is more distant than a so-called central queue with respect to said longitudinal axis and that each of the two groups of jacks providing a result offset from the longitudinal axis of the boat connects jacks of support beam carriages a said lateral file and cylinders of support beam carriages of said central file arranged on the same side of the longitudinal axis of the boat, the group of cylinders whose resultant is on the longitudinal axis of the boat connecting other cylinders of support beam carriages of at least one of said lines.
  • it comprises at least one beam of the central file of which one of the jacks is connected to support jacks of the support beams of a lateral file, the other jack of said beam being connected to support jacks support beams on the other side row.
  • At least one of the central support beams is joined at its ends by two articulations with two lateral support beams, the coupled end of each lateral beam with the central beam resting on a carriage.
  • FIG. 1 to 8 The installation shown in Figures 1 to 8 is used to support and transport horizontally a boat 11 on firm ground 12.
  • the boat 11 is moved by means of carriages 41, 43, 31, 33, 51, 53 which roll on four parallel tracks 61 to 64 ( Figures 1 to 3) or on six tracks 61 to 66 ( Figure 4).
  • the boat 11 is supported on the carriages by means of support beams 3, 4 and 5 which are stored in parallel.
  • Each beam rests at its ends on two carriages.
  • the boat is arranged so that its longitudinal axis 13 is perpendicular to the longitudinal axes of the beams passing through the support points on the carriages.
  • the support beams form at least three rows, the associated carriages rolling on at least four tracks.
  • the ends of the beams of each line are aligned parallel to the axis 13.
  • the beams 3 form the central file.
  • Beams 4 and 5 form the lateral rows.
  • the central beams 3 have their ends symmetrical with respect to the longitudinal axis
  • the boat is supported on the central beams 3 by means of central tins 21. It is supported on the lateral beams 4 and 5 by anchoring tins 22 and 23 respectively.
  • the support beams are joined by tie rods parallel to the axis of the boat and which are not shown.
  • the central beams 3 are supported by the carriages 31 and 33.
  • the lateral storage beams 4 are supported by the carriages 41 and 43.
  • the lateral storage beams 5 ' are supported by the carriages 51 and 53. Each support beam can rest on the ground or on a lifting platform with the carriages removed.
  • the carriages associated with the beams 3 of the central file roll on the central tracks 62 and 63. At least two lateral tracks are arranged in parallel and on either side of the central tracks.
  • the carriages 41 run on an outer lateral track 61, the carriages 53 run on an outer lateral track 64. Each of the tracks comprises two rails.
  • the carriages 43 and 51 roll respectively on the central tracks 62 and 63.
  • the carriages 43 and 51 roll respectively on lateral tracks 65 and 66 .
  • the support beams are arranged so as to form three rows of beams offset transversely (perpendicular to the axis 13) due to the fact that the beams 4 and 5 of the lateral rows are associated with carriages traveling on tracks separated from the tracks on which run the carriages associated with the beams 3 of the central file.
  • the midpoints of the beams that is to say the points each located at equal distances from the support points of a beam on the carriages, are aligned on a fictitious line situated between a fictitious line passing through the midpoints of the beams 4 d 'a lateral file and a fictitious line passing through the midpoints of the beams 5 of the other lateral file.
  • the ends of the central beams and the lateral beams are spaced, perpendicular to the axis 13, with respect to each other.
  • Each carriage comprises four wheels rolling in pairs on the two rails.
  • the carriage 31 comprises four wheels 311, 312, 313, 314 which are guided in bearings of the bogie frame 313.
  • the support beams are perpendicular to the rails but they can also be parallel to the rails following a change of direction by pivoting the carriages.
  • Each carriage has a hydraulic cylinder.
  • Each support beam is supported at its ends on two jacks mounted on carriages.
  • each beam 3 is supported on the jacks 32 and 34 mounted respectively on the carriages 31 and 33.
  • Each beam 4 is supported on the jacks 42 and 44 mounted respectively on the carriages 41 and 43.
  • Each beam 5 is supported on the jacks 52 and 54 mounted respectively on the carriages 51 and 53.
  • the cylinders 32 and 34, 42 and 44, 52 and 54 form three groups. In each group, the lower chambers of the cylinders are interconnected. Hydrostatic pressure ' being the same at every point of the hydraulic circuit of each group, all the forces developed by the cylinders of this group are equal. Thus in Figures 6 to 8, the broken lines, referenced I, II, III, delimit the cylinders belonging to the three groups.
  • Each group of jacks is statically equivalent to a fictitious punctual support, the result of which, marked R1, R2, or R3, is equal to the sum of the - equal - reactions of the jacks in this group.
  • the results of the three groups of jacks are located at the vertices of an isosceles triangle whose main height is parallel to the longitudinal axis 13 of the boat.
  • the two groups 1 and II give two results which are symmetrical and offset with respect to the longitudinal axis 13 of the boat.
  • the third group III gives a result passing approximately by the axis 13 of the boat.
  • the center of gravity of the ship must be located at the barycenter of the three fictitious support points, weighted by the number of cylinders constituting each of these points.
  • Each of the groups of cylinders whose result is offset comprises cylinders supporting central support beams and cylinders supporting lateral beams.
  • jacks supporting central beams 3 are connected to jacks supporting lateral beams 4.
  • jacks supporting central beams 3 are connected to jacks supporting lateral beams 5.
  • Certain beams central units rest on a jack connected to the other jack of one of the groups I or II, the other jack associated with each of these beams being connected to the jacks of the other group.
  • the two support cylinders of certain central beams are part of group III, the result of which is on the axis of the boat.
  • the two support cylinders of each lateral beam are generally part of the same group.
  • the weight of the boat is transmitted by the tins 21 on the support beams 3 and the jacks 32 and 34 are subjected to forces.
  • the docking blocks 22 were not applied against the hull of the boat, the interconnection of the cylinders of group I would tend to cause the pistons of the cylinders 42 and 44 to come out.
  • the docking blocks 23 were not not applied against the hull, the interconnection of the group's cylinders It would tend to cause the pistons of the cylinders 52 and 54 to come out.
  • FIGS 6 to 8 show various arrangements of the support beams.
  • the installation shown in Figure 6 has a higher number of central support beams than lateral support beams. It is suitable for a center keel boat.
  • the installation shown in FIG. 7 comprises more central beams and lateral beams than in the arrangement in FIG. 6.
  • the installation shown in FIG. 8 comprises, in group III, jacks supporting central beams 3 and lateral beams 4 and 5.
  • FIG. 3 shows a variant in which the lateral support beams 4 and 5 are equipped with jacks 45 and 55 respectively, serving to vertically move the docking tins 22 and 23 when the hull of the boat is curved. The balancing of the forces between the different cylinders is carried out as previously and the docking is still carried out automatically.
  • Figure 5 shows a continuous support beam that can be used in the installation.
  • This continuous beam has several support beams perpendicular to the longitudinal axis of the boat. Each beam is articulated to the adjacent beam.
  • the lateral beam 4 is joined to the central beam 3 by the articulation 71.
  • the lateral beam 5 is joined to the central beam 3 by the articulation 72.
  • the outer end of the lateral beam 4 is supported, by the intermediate of a jack, on a carriage 41 with four wheels rolling on the track 61.
  • the outer end of the beam 5 is supported, by means of a jack, on a carriage 53 with four wheels rolling on the track 64.
  • the coupled ends of beams 4 and 3 are supported, by means of a jack, on a carriage 31 with four wheels rolling on track 62.
