Definitions

• the present invention relates to a device and construction of a floating gangway, and also the shaping of joints for connecting together the gangway elements via a floating pontoon in the device.
• the invention also relates to applications of the gangway.
• the invention relates in particular to a floating gangway composed of gangway elements and pontoons that are used to stretch across a strait or a river between two land fastening points, or to be used as a gangway that is connected to a ship, in both cases to allow traffic of people and goods, such as goods transport and vehicles, across the gangway.
• gangway path is used as a designation for an extended body for all these forms of transportation.
• the known said gangway is maneuvered in that the outermost pontoon comprises a motor system with a propeller that can be driven to push it out up to a moored ship that shall be served by the gangway, and thereafter ensure that the gangway sections are folded together in the correct way and are placed in their parked position.
• Figure 1 shows a ship 10 on the water 1 1 that is moored ashore 12 with the help of forward and aft anchors 15.
• a gangway 100 runs from the shore with an outer end 14 that is connected to the ship 10 so that people and goods can be transported between land 12 and the ship 10.
• the gangway 100 is composed of three sections 20,30,40.
• the innermost end of the section 20 is coupled to a fastening point, a going ashore area, so that it can rotate on the shore 12.
• the outer end of the section 20 is connected to a pontoon C so that it can rotate horizontally.
• the inner end of the next gangway section 30 in the row is also fastened to the pontoon C so that it can rotate horizontally.
• the gangway sections 30 and 40 are connected to a common pontoon F.
• the gangway section 40 extends outwards and is placed in parallel with and next to, the side of the ship 10 via two pontoons on which the outermost gangway section 40 rests.
• Each of the pontoons H and G can form a specially constructed landing place for a gangway between the ship and the gangway bridge, such as comprising the necessary fendring that is lying at the side of the ship.
• the figure 1 also shows that the pontoon F can form a such landing location.
• the gangway construction according to the invention one can set up several separate landing locations for the transport of people and goods to and from the ship, in that the floating gangway is placed next to, and parallel with, the side of the ship and in the case shown, three such landing locations can be set up.
• Figure 1 shows a gangway with pontoon joints which according to the invention illustrate this problem.
• the pontoon C can be subjected to sideways forces that can result in sideways drifts and become uncontrollable for maneuvering from the outermost point 14.
• the aim of the present invention is to provide a new joint construction which connects two gangway sections so that the movement of the pontoon during maneuvering does not come out of control.
• the devices according to the invention are characterised in that the coupling bodies associated with said two adjoining gangway sections are connected to a locking body that limits their mutual rotating movement to between a position where the gangway sections are approximately in parallel and a setting where they form an angle a that is less than 180°, and the construction comprises a coupling body for the coordination of the mutual rotating movement of the sections so that when the one section is rotated about its mounting in the pontoon, the other section is rotated the opposite way about its mounting in the pontoon, as described in the characteristics in claim 1 .
• the independent claims 2-18 describe preferred
• the invention comprises an application of a gangway construction as a floating transport bridge to stretch across a strait or a river between fastening points on land, or as a gangway that is connected to a ship, to make transport of people possible and the transport of goods and vehicles between land and ship.
• Figure 1 shows a gangway bridge constructed according to the invention, which is used to serve a moored ship.
• Figure 1 is described previously in the text to illustrate the aim of the present invention.
• Figure 2 shows the three gangway sections folded together on the shore.
• Figure 3A shows a first embodiment of a coordinating system for two gangway sections 20 and 30, respectively, which are coupled together via a pontoon C so that they can rotate, according to a preferred embodiment of the invention.
• Figures 3B and 3C show a second embodiment for the coordination of the rotation of the sections in relation to a pontoon, in extended (fig 3B) and folded (3C) position, in that the end pieces of the gangway sections comprise round end surfaces with teeth that mutually engage with each other such as a cogwheel.
• Figure 4 shows a cross-section of the coupling according to figure 3A.
• Figure 5 shows the casing that forms the rotating joint at the end of the gangway section.
• Figures 6, 7, 8 and 9 show different rotating patterns for two gangway section ends that are coupled together via a pontoon.
• Figure 10 shows schematically how two gangway section ends can be coupled together via a pontoon.
• figure 1 is described earlier, reference is now made to figure 2 that shows the gangway 100 in a parked, collapsed position placed by the shore 14, and comprising three sections 20,30,40.
• the inner end of the section 20 is coupled at 21 to a fastening point on land 12 so that it can rotate.
• the outer end of the section 20 has a rounded end section and is connected to the inner end of the next section 30 in the row via the pontoon C.
• the second end is connected to the rounded inner end of the section 40 via 30 and 40 the pontoon F.
• the section 30 is rounded at both ends.
• the outer end of the section 40 comprises the fitting for the maneuvering of the gangway between a moored ship (extended) and folded by the shore 12.
• the invention relates mainly to the construction of each of the joints formed between the sections, for example, used between the gangway sections 20 and 30 and also 30 and 40 via the respective pontoons C and F.
• FIG 3A shows the coupling between the gangway sections 20 and 30 via the pontoon C and a first embodiment of the rotating coordination between the two adjoining sections 20,30.
• the pontoon C is shown as a circular tank (or with any other shape) that floats in water shown by the waterline 1 1 in figure 4.
• the centre of the pontoon is shown by 61 .
• respective rotating bolts 22 and 24, respectively extend upwards and define the axis of rotation of the rounded ends of the two sections 20 and 30, respectively.
• the axis 22 and 24, respectively are placed diametrically opposite each other and a line between them runs through the centre 61 .
• respective rotating discs 23 and 25, respectively are fitted, which casing-formed rotating pegs 60,62 from the underside of the sections ends are set up to be able to be rotate via a flat lower flange part 67.
• the casings 60,62 are fastened at the underside of the end parts of the respective gangway sections 20,30 and each of these is threaded down over their respective upwardly extending peg 22 and 24, respectively, in the pontoon.
• the extended sections 20 and 30, respectively shall only be able to swing towards each other the one way, as shown in figure 1 , as the two shall only be able to be folded together to the left. It shall not be possible to swing the section 30 towards the right past the position where the sections are directly aligned with each other 180°.
• a locking body is used in the form of a wire or a chain 70, the two ends of which are fastened to respective end fastening points 72 and 74, respectively, in the two gangway sections 20,30.
• the locking wire 70 is adapted so that the sections cannot be rotated more than 180°. So that the sections that are shown in figure 1 shall be folded together naturally the right way, it is preferred that the locking wire limits the straightening out of the two sections to a little below 180°, as will be explained in the following.
• a suitable angle range that will give a desired swing pattern is between 160° and 175°, with a preferred setting being about 170°.
• the rotation of the two sections is further coordinated so that when the one section is rotated about its mounting 22 in the pontoon, then the other section is also rotated about its mounting 24 in the pontoon, but in the opposite direction.
• a flexible stay 52 in the form of a wire or chain is stretched from the edge of the periphery 56 of the rotating casing 60 all the way up to the opposite side 59 of the rotating casing 62, i.e. that the two ends of the wire run along a pulley groove about the casing up to the fastening points.
• a corresponding, flexible stay 54 (wire/chain) is stretched in the opposite direction around the casings from the same peripheral point 56 on the casing 60 to the same opposite away- facing side of the casing 62 and also fastened at the point 59 on the casing.
• the wire fastening point 56 in the casing 60 preferably lies in the longitudinal centre line A1 of the gangway section 20, while the wire fastening point 59 in the casing 62 lies in the longitudinal centre line A2 of the gangway section 30.
• the stays of wire/chain form an X- shape. So that the two stays 52 and 54, respectively, shall not touch each other when the sections are rotated, they are arranged at different heights on the outside of the casings 60,62 as shown in figure 4. With the stays fastened, a mutual moment of rotation is set up when the sections are rotated, which depends on the distance between the fastening point of the stay in the rotating casing and the axis of rotation. Now, the two sections will be able to move in synchrony or in a coordinated way away from each other or towards each other.
• Each stay 52 and 54 is preferably a relatively tensile resistant but flexible, body, such as a chain put together by chain links or a wire.
• the figures 4 and 5 show that each casing 60,62 can comprise three external flanges (figure 5) 61 ,63,65 mutually spaced apart around the circumference and which, in pairs, 61 ,63 and 63,65 form between them grooves that can take up parts of the wires 52 and 54, respectively, in an arch-shape and guide these when the sections are mutually rotated.
• the underside or the under surface 67 of the bottom flange forms a rotating support surface against the top surface of the rotating discs 23 and 25, respectively.
• the two gangway sections can have a mutually arbitrary location when the wires 52,54 are fitted in the points 56 and 59, respectively. But the sections 23,30 and 30,40, respectively, are only moved mutually together to fold together and lie in parallel to each other as shown in figure 2, or be moved away from each other to an angle a little under 180 degrees.
• the wire or the chain is arranged in an endless number eight figure form around the two casings and is so taut in the casing grooves that the wire/chain cannot slip or slide in the pulley groove.
• said coordinated or synchronised rotary movement between the sections can be provided in that each of the two adjoining ends of the sections 20,30 and 30,40, respectively, form a half circle, the arch of which is formed with a set of cogs 80 and 82, respectively, (as cogwheels). These half cog wheels mutually engage with each other, which will set up the wanted swing pattern.
• Figure 4C shows the situation for the setting of these cogwheels when the sections lie in parallel with each other.
• each pair of the sections 20,30 and 30,40, respectively, is mutually fitted in alternately opposite directions.
• the sections 20 and 40 are mutually in parallel and sticking out, while the middle section 30 forms an angle of a degrees below 180 degrees with the sections 30 and 40, for example, 170 degrees.
• the figures 6 and 7 illustrate this swing pattern.
• An arch marked a is inserted which provides the possibility for mutual swings between the sections 20 and 30, i.e. the outermost points are shown.
• Figure 6 shows the same situation as figure 3, while figure 7 shows the sections 20,30 folded together into a parked position as in figure 2.
• figure 8 shows the mutual position of the sections 30 and 40 as in figure 1
• figure 9 shows these sections folded together to a parked position as shown in figure 1
• each gangway section 20,30,40 is composed of three part sections, here shown by the part sections 20a, 20b and 20c, and supported by two additional floating pontoons A and B associated with the two part sections 20b and 20c, respectively.
• two adjoining part sections are connected via a horizontal joint - a hinge joint, illustrated in figure 10.
• the horizontal hinge joint is placed immediately outside an end edge of the pontoon, i.e. that two adjoining part sections 20a and 20b are coupled together via the horizontal joint H1 that is supported by the pontoon A.
• the joint H1 and thus the coupling together of the two sections, is placed immediately outside the end edge of the pontoon.
• the end of the part gangway section 20b rests on the top surface of the pontoon as shown in the figure and is directly connected to the hinge construction that is supported by the pontoon.
