The invention relates to crossing-bridge means, and more specifically to the ferries and pontoon bridges.

Known motor link (see RF patent №2120880 from 27.10 1998), consisting of a body with a built-in deck roadway, with a compression and butt nodes on the side of the engine with the transmission placed in the hull, propulsion and steering unit made in the form of a swing-out column with a screw in the nozzle, and a removable peregruzochny devices placed on the deck along the sides.

A disadvantage of the known motor link is that it while moving the Shuttle ferry provides him with additional resistance of the lower body portion extending beyond the bottom coupled with a motor link pontoon units, due to the greater precipitation.

It is also known motor link (prototype - see RF patent №2098314 from 10.12.1997,), including wodoslawsky case with misbelieve butt nodes on the sides, are accommodated in the housing of the motor and men jet propulsion, United articulated with the body by two folding pontoon and the mechanism of their disclosure and folding.

The disadvantage of this motor link is the same as or similar increased resistance Shuttle ferry caused a projecting part of the housing of the folding pontoon at the bottom of the pontoon sections. As a consequence, the speed of dvijeniyami and its performance is reduced.

The objective of the invention is to reduce the resistance of the Shuttle ferry, moving from side to side parallel to its longitudinal axis, by improving the aerodynamics serving the lower part of the motor element.

The solution of the stated problem is achieved by the fact that in the engine lineup, including wodoslawsky case with butt nodes on the sides, are accommodated in the housing of the motor and men jet propulsion, United by hinges with the case of two folding pontoon and the mechanism of their opening and closing, each of the folding pontoon supplied from the external side poteryannym rotary hydrodynamic shield with guide pivotally connected to the folding pontoon near its bottom, and a rotation mechanism of this shield is made in the form of a hydraulic cylinder with a rod fixed in the housing of the folding pontoon, at the end of the rod is fixed thrust roller placed in the guide hydrodynamic shield.

The use of the proposed solution will reduce the resistance of the Shuttle ferry and, as a consequence, to increase its speed and performance by 20-25%.

The invention is illustrated by drawings, which depict: figure 1 - motor link, side view; figure 2 is a section a-a in figure 1; figure 3 is a node I in Fig 2; figure 4 - hydrodynamic Board with me what Anisman rotation; figure 5 - motor component of the ferry; 6 - motor link in the transport position.

Motor link includes wodoslawsky case 1 butt joint 2 on the sides, are accommodated in the housing of the motor 3 and men jet propulsion 4. With the housing 1 are connected by hinges 5 and 6 folding pontoon 7 and 8, is supplied from the outer sides of the rotary hydrodynamic shields 9 and 10 connected with a folding pontoon hinges 11 and 12. Each hydrodynamic shield patorian torsion 13. In folding the pontoons 7 and 8 are installed hydraulic cylinders 14 and 15, the rod 16 of each end thrust roller 17, is placed in the guide 18 hydrodynamic shield. The drive cylinders is supplied from the hydraulic motor of the motor unit. Folding the pontoons are provided on the outer sides of the joint nodes in the form of a fork 19 with the pin and ear 20 for connection with a pontoon links 21 and 22 during Assembly of the ferry. The opening mechanism and the folding of the folding pontoons made in the form of two struts 23 and 24, mounted on the deck of the hull-borne hull in the stern part. The rack is equipped with bypass blocks 25 and 26, which superovulate ropes attached at one end to a button on the folding pontoon boats and other end to the winch hydraulic engine motor link. Motor link carried by the Usha folded on the pontoon car.

The proposed device operates as follows. Pontoon motor vehicle with a suitable link to the water's edge back and stops. Next motor link disclose using a cable opening mechanism and folding, driven from the engine of the motor link or from the vehicle. Open motor link unloaded pontoon car on water and with the help of hydraulic cylinders 14 and 15 turn hydrodynamic shields 9 and 10 at the angle of about 70°-80°. When the rotation of the shield thrust roller 17 of the rod 16 rolls on the back of the shield in the guide 18. After this motor link set between the pontoon links 21 and 22, connecting them with each other butt nodes 19 and 20 and vidvigayt rods in hydraulic cylinders. This hydrodynamic shields 9 and 10 under the action of torsion 13 to touch the edges with pontoon bottoms of the links 21 and 22. When the movement of the ferry hydrodynamic shields will smooth the flow before serving part of the body of the folding pontoon motor link. After the ferry crossing ferry disassemble motor and pontoon units, hydrodynamic shields under the action of torsion will return to the transport position, the motor link load on the pontoon car and folded by turning the hinged pontoons using winches and ropes, zapasovany on Obvodny the e blocks 25 and 26 of the racks 23 and 24.

Motor link, including wodoslawsky case with butt nodes on the sides, are accommodated in the housing of the motor and men jet propulsion, United by hinges with the case of two folding pontoon and the mechanism of their disclosure and folding, characterized in that each of the folding pontoon supplied from the external side poteryannym rotary hydrodynamic shield with guide pivotally connected to the folding pontoon near its bottom, and a rotation mechanism of this shield is made in the form of a hydraulic cylinder with a rod fixed in the housing of the folding pontoon, at the end of the rod is fixed thrust roller placed in the guide hydrodynamic shield.

FIELD: floating bridges, for instance temporary bridges for load transportation over ice.

SUBSTANCE: structure includes ice blanket in which vertical holes are drilled for the full bridge structure length so that the holes are located from both bridge sides. Reinforced concrete blocks connected to ropes are inserted through the holes so that the blocks are located under the ice blanket. Discs having diameters exceeding hole diameters are connected to upper block ends. Rope lengths are selected to prevent ice blanket movement in upward direction with respect to initial ice position if flexural-gravity waves are generated in ice blanket.
