Foldable link

 

(57) Abstract:

Usage: crossing-bridge crossings. The inventive foldable link is pivotally connected to two outer and two middle pontoon mounted with tronzo medium pontoons butt nodes. On the transom of each pontoon is installed on one side, near the bottom, a hinged folding streamlined shield with scalloped cutouts, attached to the upper trance spacer 12. The upper part of the shield is connected to the lower hinge clamping springs and fixed by bolts 10. 6 Il.

The invention relates to crossing-bridge means, in particular, to a floating bridges and ferries.

Known bridge link French pontoon Park TA-1 see the journal "Foreign military review ". W 4 1988, S. 32/ containing swivel United middle and four extreme pontoon installed on the transom of the middle pontoon butt nodes.

The disadvantage of a bridge link is that it has great resistance to water transom forward due to poor aerodynamics.

As the closest analogue made foldable link containing pivotally connected the C upper and lower hinge parts, see United the application of Germany N 3510778, CL 63 In 35/36, publ. 1986 /.

The disadvantage of this 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.

The technical result of the invention is to increase the speed of the link transom forward when it is a single use or a Shuttle ferry by improving the aerodynamics of the transom level. It is achieved by the folding link containing pivotally connected two outer and two middle pontoons, as well as sleek folding boards with spacers, each of which has upper and lower hinge parts of the United boards made with scalloped cutouts and pivotally attached to the transom of the pontoons to one side of the folding element, and the spacer panels attached to the upper parts of the transom and the top and bottom of each of the shields are connected clamping springs and provided with locking latches, and on the transom medium pontoons installed butt nodes.

The invention is illustrated by drawings, where Fig.1 shows a foldable link in the plan defined foldable Ob side of the folded shield: Fig.5 view B in Fig.3: Fig.6 view In Fig. 4. Foldable link is pivotally connected two extreme pontoon 1 and two middle pontoon 2 installed on the transom medium pontoons 2 butt sites, made in the form of the ear 3 and the plug 4 with pin.

In addition, on the transom of each pontoon folding link with one side mounted folding streamlined panels 5, 6, 7 and 8 with scalloped cutouts. Each folding streamlined shield consists of upper and lower parts connected by a hinge with clamping springs 9 and fixed in the open /working/ position by means of bolts 10. The upper part of each shield is provided with a lug 11 for fastening one end of the spacer 12. The panels 5, 6, 7 and 8 mounted on the transom of the pontoons 1 I 2 near the bottom hinge using a finger 13 to lugs 14 and fixed in the folded /transport / clamping position by means of hinge brackets 15. The spacer 12 is fixed to the lug 11 with a fork and pin 16 connected to rasaraj the cable 17 and to the transom by means of hook 18 and the lugs 19

The device operates as follows.

To ensure the efficiency of movement of foldable link transom forward folding streamlined panels 5, 6, 7 and 8 and is transferred to the working position. To do this, turn the bracket 15. oigimi 10. Then the upper end of each foldable shield 5,6,7 and 8 away from the top of the transom of the corresponding pontoon 1 and 2 and are secured in this position by the spacer 12 with pin 16. Before laying the regular ramp on shore for unloading or loading equipment spacers 12 is removed from the hooks 18 and stack the boards attached to the middle of the pontoons 2 on the ground. Further down the ramp to the shore unload or load steam, raise apparel up and folding of the shield is moved into the working position, pinning them to the strut 12, and then the ferry leave from the shore.

Translation streamlined folding of the panels into the transport position is carried out in reverse order.

Foldable link containing pivotally connected two outer and two middle pontoon and sleek folding boards with spacers, each of which is made of upper and lower pivotally connected parts, characterized in that said panels are made with scalloped cutouts and pivotally attached to the transom of the pontoons in the areas adjacent to the bottoms of the pontoons to one side of the folding element, and the spacer panels attached to the upper parts of the transom and the top and bottom of each of the panels associated clamping spring and the mass is

FIELD: transport.

SUBSTANCE: invention relates to pontoon-ferry craft designed for crossing water basins. Pontoon link is lowered by guides in folded state. When link exits the guide extreme pontoons 1, 2 turn on axles 3, 4 due to a moment developed by pontoon weight force applied to its center of gravity. Engaged by extreme pontoons cables 10 actuate pyrocartridges, as a result, pressure increases in chambers 9 pulling apart pontoons 5, 6 tightened by cord 8 and creates in the last one a large stress, which leads to its destruction. As a result chambers 9 fastly increase in volume under pressure of combustion products, which leads to turn of pontoons 5, 6 about axis 7 and increase of angle between them. At drop in water immersion of ends of pontoons near chambers 9 is decelerated by earlier action of buoyancy force on them, the other ends move faster, which results in closing of ends of middle pontoons with each other and with the ends of extreme pontoons. Locks 11 are automatically closed and pontoon-bridge link is ready for operation immediately after its discharge into water.

EFFECT: technical result consists is faster passage of water basins and less labour force required providing the possibility of river crossing at high flow rate and improved operational characteristics.
