The invention relates to crossing-bridge means, and more particularly to a folding pontoons and ferries.

Known river link pontoon-bridge Park PPM (see Guide pontoon-bridge Park RAP. Voenizdat, 1965, p.16-54, 8), containing pivotally connected two outer and two middle pontoon and ramp.

A disadvantage of the known river link is that when moving the transom forward when it is a single use or a Shuttle ferry link has a high resistance and therefore low speed on the water.

It is also known collapsible link (prototype - see RF patent №2063361, IPC6WV 35/36 from 10.07.1996 g)containing pivotally connected two outer and two middle pontoon ramps and sleek folding boards with spacers, each of which is made of upper and lower pivotally connected parts and pivotally attached to the transom of the pontoons in the areas adjacent to the bottom side of the folding element, and the spacer panels attached to the upper parts of the transom.

The disadvantage of this foldable link is that for loading vehicles on the ferry or her discharge, disconnect the struts from the transom of the pontoons and tuck folding streamlined shields on the ground, and then lower the ends of the ramps on the beach. After loading the equipment on the ferry or her viruscina the ends of the ramps to raise up and bring sleek folding the panels into position, secure the spacers to the transom of the pontoons. These operations with shields laborious and time consuming, especially when muddy shores, when the boards are pressed into the soil.

The objective of the invention is to reduce the complexity and duration of the loading equipment on the ferry and unloading due to the exclusion of works by lowering and lifting folding streamlined shields.

The solution of the stated problem is achieved by the folding link containing pivotally connected two outer and two middle pontoon ramps and folding streamlined panels located on one of the transom folding link, each ramp provided on the bottom plane of the longitudinal rails, and each folding streamlined shield made of medium and pivotally connected to the two outer sections, fixed with respect to the middle section braces, while the middle section is equipped with a stop and connected with the longitudinal rails of the ramp is movable by means of rollers, placed on the top edge of the shield, and the pivot - rods, pivotally attached at one end to the eyelets on the back plane of the middle section and the other end is installed on the tubular cylinder, the axes on the sides of the ramp.

The use of the proposed device will allow for a ferry crossing to facilitate the steps of the calculation with foldable streamlined sitamaquine level and to reduce the time of loading equipment on the ferry and its discharge is approximately two times.

The invention is illustrated by drawings, which depict: figure 1 is a foldable link with sleek foldable panels; figure 2 is a view As in figure 1; figure 3 - a view B in figure 1; figure 4 - position of the ramp and shield during loading or unloading machinery; figure 5 is a view In figure 3; figure 6 is a ramp with a folded shield, prepared for transportation; 7 - type G figure 6.

Foldable link is pivotally connected two extreme pontoon 1 and two middle pontoon 2, is fitted on the transom butt sites, made in the form of the ear 3 and the plug 4 with the probe. On one of the folding transom link has two folding streamlined shield 5 and 6. On the transom medium pontoons 2 hinged hooks ramps 7 and 8 held in the working position the crane-beams 9 and 10. In decks extreme pontoons 1 made niche 11 and 12. Each ramp 7 and 8 provided on the bottom plane of the longitudinal guides 13, and side walls, in the area of grunts - axis 14. Each folding streamlined shield 5 and 6 are made of the middle section 15 and pivotally connected to the two outer sections 16 and 17 on either side of this section. The middle section 15 provided on the upper edge of the two rollers 18 and the lower edges of the lugs 19 and the stop 20. The middle section is connected to the longitudinal guide 13 the ramp is movable by means of rollers 18, which can move in these n the sending, and rotatable - with the help of rods 21, pivotally attached to one end of the axles 22 to lugs 19 on the back plane of the middle section 15, the other end of the axis 14 to the side walls of the ramp. The rod 21 provided on the end connected to the ramp, a tubular cylinder 23, is rigidly attached to the rod. In the open (working) position of the shield folding each of the side segments 16 and 17 prevents brace 24, one end of which is placed with the possibility of longitudinal displacement of the lug 25 of the outer units, and the other end is wearing is movable on the axis 14 of the ramps 7 and 8. Complete the exit end 24 of the cross stay lugs 25 is prevented by the stopper 26. On the extreme ends of the sections 16 and 17 posted by transport screed 27.

Foldable link in the folded position is carried by the pontoon car.

The proposed device operates as follows. Pontoon car with a folding link suitable back it up to the water's edge and unloads the level of the water. After disclosure of the foldable link on the water and snapping pontoons between a removed using a crane beams 9 and 10 of NIS 11 and 12 of the ramps 7 and 8 with folded panels 5 and 6 and hang their hooks on the transom medium pontoons 2. Then turn the ramp 7 and 8 in the side deck foldable link, remove transport screed 27, throw back at sections 16 and 17 on each side of the middle section 15 and set Rasko is s 24 in the lugs 25, and the other end of the cross stay put on the axle 14 on the side walls of the ramp. After that ramps 7 and 8, her sleek panels 5 and 6 rotate in working position to the bearing lugs 20 in the ear 3 and the plug 4 of the joining nodes. Then foldable link connect to steam through the ear 3 and the plug 4 with other foldable links, fitted with the same butt sites on the transom. This links with foldable streamlined panels 5 and 8 are placed on the ends of the ferry. After you approach the ferry to the shore for loading equipment by turning pontoon scrap set by the end of the tubular cylinder 23, turn streamlined panels 5 and 6 close to the bottom plane of the ramps 7 and 8. While the rollers 18 of the panels 5 and 6 are moved in the guide rails 13 of the ramps 7 and 8 towards the end of the ramp (at the position of the pontoon scrap shown in figure 4 in phantom lines). Next, the lower ends of the ramps to the ground, detach the ropes crane beams 9 and 10 from the ramp, turn the crane beams 9 and 10 and load the equipment on the ferry. At the end of the loading equipment gear ropes crane beams 9 and 10 for the ramps 7 and 8, raise their ends in the upper position and using a pontoon Lomov, inserted the ends into the tubular head 23, translate streamlined panels into position. The movement of the ferry on the water carry forward transom folding link, equipped obayemi and shields. Steps with ramps and sleek shields when unloading equipment from the ferry is similar to the behavior of these elements during loading equipment on the ferry. After the ferry crossing ferry dismantle, remove braces 24 with the axis 14, is folded sections 15, 16 and 17 each wrap shield 5 and 6 in the package and fix their ties 27, then remove the crane-beams 9 and 10 of the ramps 7 and 8 is pressed against the lower planes packages of folded sections streamlined panels 5 and 6 with transom medium pontoons 2 and put the ramp in recesses 11 and 12 on the deck at the pontoons 1 foldable link. After that, the link is folded by using a pontoon car and load it on this car.

Foldable link containing pivotally connected two outer and two middle pontoon ramps and folding streamlined panels located on one of the transom folding link, wherein each ramp provided on the bottom plane of the longitudinal rails, and each folding streamlined shield made of medium and pivotally connected to the two outer sections, fixed with respect to the middle section braces, while the middle section is equipped with a stop and connected with the longitudinal rails of the ramp is movable by means of rollers, placed on the top edge of the shield, and the pivot - rods, pivotally attached at one end to the por is utinam on the back plane of the middle section, and the other end is installed on the tubular cylinder, the axes on the sides of the ramp.
