The invention relates to crossing-bridge means, and more particularly to a floating bridges and ferries.

Known river floating link road collapsible bridge, consisting of two pontoons rectangular form, the hinged interconnected longitudinal edges and is fitted on the transom stikova the only one payload of 60 tons with limited stability period (up to 2 m/s).

Object of the invention is the empowerment of river management on the build floating bridges of different capacity with increased resistance to flow.

The solution of the stated problem is achieved by the fact that in the river level, which consists of two pontoons rectangular form, the hinged interconnected longitudinal edges near the bottom and is fitted on the transom butt nodes, each pontoon is supplied from the hard bottom in the form of a triangular prism inscribed in its dimensions Radome, rotatable about an axis placed from the bottom at a distance greater than half the height of the pontoon, with one face of the fairing equipped butt sites, made for example in the form of the ear and plug with pin for connection of the link with other parts, moreover, in the upper position of the fairing that face is turned to the roadway, forming kalecoauto, and the other edge of the fairing is a continuation of the smooth bends of the link.

In Fig.1 shows a river link in the folded transport position, a view of the transom of Fig.2 river link in the open (operating) position with the fairing in the lower position, a view of the transom of Fig.3 is a view along arrow a in Fig.2; Fig.4 river link in the open (working the same); in Fig.5 cross-section of two-lane floating bridge; Fig.6 cross section of a three-way floating bridge.

River link consists of two pontoons 1 and 2 of rectangular shape, connected near the bottom by a hinge 3. On the boat pontoons placed butt sites, made for example in the form of the ear 4 and the plug 5 with the probe. Skew the location of the butt of the nodes in the Assembly of floating bridges and ferries connect the links between any transom. In the deck of the pontoons built roadway 6 and 7. The pontoons are supplied from the bottom of the fairing 8 and 9 are rotatable about the longitudinal axis 10 and 11, positioned relative to the bottom of the pontoons at a distance greater than half the height of the pontoon. In the lower position fairings inscribed in the dimensions of the pontoons and held by means of hooks 12 and 13 for the buttons 14 and 15. In the upper position of the fairing is secured by means of lugs 16 and 17 with the pins. Each fairing equipped b nodes 18 and 19, by design, similar to the butt of the sites hosted on the transom of the pontoons. In the folded transport position, the pontoons are connected by means of a hook 20, and in the open (operating) position with the deck lock 21. To rotate the fairing SL is 2">

The device operates as follows. Opening the hook 20, river link unloaded vehicle on water samokutyayev or by using a crane. Under the action of gravity and backwater link is disclosed. After that, close the deck lock 21. Further, depending on the type of the collected floating bridge fairings leave in the down position or rotated to the top position. Before turning fairings in the upper position the hooks 12 and 13 is removed from the buttons 14 and 15. Fairing turn two people one on each transom. They operate pontoon levers, insert the ends in the radial holes of the cylindrical bushing 22. In the upper position of the fairing is fixed with the eyelets 16 and 17 with the pins. When building the bridge river links connect to each other in the longitudinal direction through the ear 4 and the plug 5 with the probe, and in the transverse direction (along the stream) using the joint nodes 18 and 19, drives to the pins which are derived on the roadway pontoons. All types of floating bridges fairings extreme pontoons with grassroots and horse sides of the bridge should be rotated to the top position. This is one side fairings limits the width of the roadway of the bridge.

RIVER LINK, consisting of two pontoons rectangular form, the hinged interconnected longitudinal edges near the bottom and is fitted on the transom butt nodes, wherein each pontoon is provided with a side plate hard in fare triangular prism inscribed in its dimensions Radome, rotatable about an axis placed from the bottom at a distance greater than half the height of the pontoon, with one face of the fairing equipped butt sites, made in the form of the ear and plug with pin for connection of the link with other parts, and in the upper position of the fairing that face is turned to the roadway, forming kalecoauto, and the other edge of the fairing is a continuation of the smooth contours of the link.

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.
