The invention relates to the field of crossing-bridge means, and more particularly to a transportable ferries.

Known collapsible steam (prototype), including United in one a number of joint nodes alternating wodoslawsky folding river links and means of motorisation in the form of motor units, and coastal links placed in the fore and aft ends of the ferry.

The disadvantage of this ferry is the difficulty of its operation in shallow coastal castrejana clogging and breakage disable propulsion and steering complex engine management, located closer to the forward end of the ferry, and only after taking off the coast re-enable. This maneuverable quality ferry worsen, and in the presence of his mooring to the shore and the waste is extremely difficult.

The invention is directed to solving the problems of improving performance characteristics of the boat into the shallow water conditions.

The invention consists in that the folding transportable ferry, including United in one a number of joint nodes wodoslawsky folding pontoon river links and the associated forward end of the coastal ferry link, and the means for motorisation in the form of motor units, equipped with propulsion and steering systems, engine parts are connected by flanges and attached to the transom aft end of the ferry, with propulsion and steering complexes are located on the side of the boards the ferry opposite to each other.

In Fig.1 shows a collapsible transportable steam, view in plan; Fig.2 - the same, lateral view; Fig.3 - section a-a in Fig.2; Fig.4 is a view along arrow B in Fig.2.

Collapsible transportable steam consists of displacement folding river pontoon parts 1, coastal level 2 and motor Beregovoe link differs from river wedge-shaped form. Average and extreme pontoons are connected by hinges 6 and 7. In the open (operating) position the pontoons are closed deck locks 8 and bottom locks 9. On the transom medium pontoons installed butt nodes in the form of a fork 10 with the probe and the ear 11. Skew the location of the butt joints allows to combine the links between any transom. Motor link consists of a housing 12 in which is placed the engine 13 and a transmission 14, which leads into effect propulsion and steering complex, made for example in the form of a swing-out column 15 with a screw in the nozzle 16. In the deck 17 of the housing 12 is embedded roadway, and on the sides of the installed joint nodes in the form of a fork 18 with the pin and ear 19, similar to the butt of the sites hosted on the transom river links. Coastal link is equipped with two lifts 20 to change its angle relative to the ferry.

Steam works as follows. After discharge of the water in coastal and river levels close deck locks 8 and bottom locks 9. Then river links interconnected by a plug 10 with the probe and the ear 11. To the resulting tape is connected with one end of the coastal link, and the other end of the motor units. Moreover, motor parts, connected them together with a fork 18 with the pin and ear 19. When propulsion and steering complexes have on different sides relative to the longitudinal axis of the ferry. After lifting the end of the coastal link using lifts 20 at some angle ferry served to the place of loading equipment. The docking of the ferry to the shore carry forward, and push - back. When opposite the placement of the propulsion and steering of the complexes relative to the longitudinal axis of the ferries provides ferry good maneuverability and hold it on the shore from demolition over. Location of motor units in the aft end of the ferry eliminates the possibility of breakage when mooring to the shore.

COLLAPSIBLE TRANSPORTABLE STEAM, including United in one a number of joint nodes wodoslawsky folding pontoon river links and the associated forward end of the coastal ferry link, and the means for motorisation in the form of motor units, equipped with propulsion and steering systems, characterized in that the motor units are interconnected sides and attached to the transom aft end of the ferry, with propulsion and steering complexes are located on the side of the boards the ferry opposite to each other.

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.
