Description

A multipurpose gangway for vessels
The present invention relates to a movable gangway for a vessel, comprising a supporting base which can be mounted in a static way on said vessel, and a first and a second gangway element, in which said first gangway element is connected by its proximal end to the supporting base so as to be rotatable about a vertical axis, slewing rotation means being provided for rotating the first gangway element about the vertical axis, and is hinged by its proximal end to the supporting base about a horizontal main hinge axis, main elevating rotation means being provided for rotating the first gangway element about the hinge axis with respect to the supporting base.
The movable gangway according to the invention is characterized in that said second gangway element is connected by its proximal end to a distal end of the first gangway element, so as to be hinged on a secondary hinge axis parallel to the main hinge axis, secondary elevating rotation means being provided for rotating the second gangway element about the secondary hinge axis with respect to the first gangway element, in which said gangway can be placed in a lowered position in which said first and second gangway elements are aligned with each other to form together a walking surface.
Specific embodiments of the invention are defined in the dependent claims.
A preferred, but non-limiting, embodiment of the invention will now be described, with reference to the attached drawings, in which:
Figure 1 is a perspective view from above of a gangway for a vessel according to the invention, in a lowered position;
Figure 2 is a view in side elevation of the gangway of Figure 1;
Figure 3 is a perspective view from below of the gangway of Figure 1 ;
Figure 4 is a perspective view from below of the gangway of Figure 1 in a raised position;
Figure 5 is a perspective view from above of the gangway in the position of Figure 4;
Figure 6 is a simplified view of the gangway of Figure 1, installed on a vessel, in the raised position; and Figure 7 is a simplified view of the gangway of Figure 1, installed on a vessel, in the lowered position.
With reference to the drawings, these show a gangway 1 according to the invention, which can be installed on a vessel S (a portion of which is shown in Figure 6). The gangway comprises a supporting base 2, which can be mounted in a static way on the vessel S. The gangway 1 also comprises a first and a second gangway element 3, 4, and preferably also a third and a fourth gangway element 5, 6.
The first gangway element 3 is connected by its proximal to the supporting base 2 so as to be rotatable about a vertical axis z. The supporting base 2 therefore comprises a static lower part 21 which can be fixed to the vessel S, and a rotatable upper part 22, these parts being interconnected by a bearing 23 which allows the rotatable upper part 22 to rotate about the vertical axis z. The supporting base 22 is associated with slewing rotation means 24, for example an electric or oleopneumatic motor, for rotating the gangway 1 about the vertical axis z.
A fork structure 25 is positioned on the rotatable upper part 22 of the supporting base 2. The first gangway element 3 is connected by this fork structure 25 to the supporting base 2 so as to be hinged about a main horizontal hinge axis xl. The structure of the first gangway element 3 is generally of the elongate box type, and it is provided with a first gangway board 31 on its upper side. The first gangway element 3 is associated with main elevating rotation means 35 for rotating the first gangway element 3 about the main hinge axis xl with respect to the supporting base 2. hi particular, in the example shown, the main elevating rotation means 35 are made in the form of a double-acting hydraulic cylinder, whose lower end is hinged, at x2, to the fork structure 25 of the supporting base 2, and whose rod has a free end hinged at x3 to the first gangway element 3.
The second gangway element 4 is connected by its proximal end to a distal end of the first gangway element 3 so as to be hinged about a secondary hinge axis x4 parallel to the main hinge axis xl. The structure of the second gangway element 4 is generally of the elongate box type, and it is provided with a second gangway board 41 on its upper side. The second gangway element 4 is associated with secondary elevating rotation means 45 for rotating the second gangway element 4 about the secondary hinge axis x4 with respect to the first gangway element 3. In particular, in the example shown, the secondary elevating rotation means 45 are made in the form of a pair of double-acting hydraulic cylinders positioned parallel to each other, with their lower ends hinged, at x5, to the first gangway element 3, and with the free end of each of their rods hinged, at x6, to the second gangway element 4.
As shown in Figures 1 to 3, the gangway 1 can be placed in a lowered position in which the first and second gangway elements 3, 4 are aligned with each other to form together a walking surface, formed by the gangway boards 31 and 41. In the example described here, this condition can be produced simply by correctly determining the positions of the hinge points xl, x2, x3, x4, x5 and x6 according to the strokes of the cylinders 35 and 45. Preferably, the cylinders 35 and 45 can be actuated in a coordinated way (by means of a suitable control unit which is not shown) so as to keep the orientation of the second gangway element 4 constant during the raising of the first gangway element 3. Thus the gangway board 41 is kept horizontal during the raising of the first gangway element 3.
The third and fourth gangway elements 5, 6 complete the preferred embodiment of the gangway shown in the drawings. The third gangway element 5 is connected by its proximal end to a distal end of the second gangway element 4 so as to be hinged about an adjusting hinge axis x7 parallel to the main hinge axis xl. The structure of the third gangway element 5 is generally of the elongate box type, and it is provided with a third gangway board 51 on its upper side. The third gangway element 5 is associated with adjusting elevating rotation means 55 for rotating the third gangway element 5 about the adjusting hinge axis x7 with respect to the second gangway element 4. In particular, in the example shown, the adjusting elevating rotation means 55 are made in the form of a double-acting hydraulic cylinder whose lower end is hinged at x8 to the second gangway element 4 and whose rod has its free end hinged at x9 to the third gangway element 5. The stroke of the adjusting cylinder 55 is much shorter than the strokes of the movement cylinders 35 and 45, and enables small adjustments to be made to the inclination of the third gangway element 5 with respect to the rest of the gangway 1. This can be useful, for example, in a case in which, in the raised configuration of Figure 4, the second gangway element 4 cannot reach the height which it is required to reach.
The fourth gangway element 6 is mounted slidably inside the third gangway element 5, so as to form a telescopic extension structure which can be elongated in a known way to enable a predetermined maximum length of extension to be achieved, hi Figures 4 and 5, the fourth gangway element 6 is shown in the condition of maximum elongation, while in Figures 1 to 3 it is shown in the condition of maximum retraction. The structure of the fourth gangway element 6 is generally of the elongate box type, and it is provided with a fourth gangway board 61 on its upper side. The fourth gangway element 6 is associated with translation means 65 for translating the fourth gangway element 6 with respect to the third gangway element 5 in the longitudinal direction of the latter. In particular, in the example shown, the translation means 65 are made in the form of a double-acting hydraulic cylinder whose lower end is fixed, at xlO, to the third gangway element 5, and whose rod has a free end fixed (the fixing point is not shown in the drawings) to the fourth gangway element 6.
Even more preferably, a hydraulic hoist (not shown in the drawings) is installed inside the fourth gangway element 6, for winding and unwinding a lifting cable 66 (shown in Figure 2) which emerges from the distal end of the fourth gangway element 6. Thus the gangway 1 can also be used as a crane.
Figures 6 and 7 show the gangway 1 installed on a vessel S, particularly on an installation plane P of this vessel, for example on a rear deck. On this installation plane P there is formed a housing H such that, when the gangway is in the lowered condition of Figures 1 to 3, the gangway boards 31, 41 and 51 are positioned level with the installation plane P. Thus these boards form a walking surface together with the surface of the installation plane P. The control system of the gangway 1 is designed to prevent the rotation of the bearing 23 about the axis z, the adjustment of the elevation of the third gangway element 5 and the emergence of the fourth gangway element 6 when the gangway 1 is in the lowered position in the housing H. However, these movements can be executed when the gangway is in the raised position, particularly in the position of maximum elevation shown in Figures 4 to 6. When the gangway 1 is in the raised position, in order to allow access to the gangway boards 41 and 51 of the second and third gangway elements 4 and 5, if an accessible raised point such as a set of steps L is available only at a certain distance from the gangway 1, it is possible to provide an access gangway G which can be positioned (by manual or motorized means) to cover this distance. This access gangway G can be retracted into a suitable housing when not in use.
