The invention relates to crossing-bridge means, and more specifically to the tugs.

Known motor link (see RF patent N 2020108, class B 63 B 35/54, 30.09.1994), comprising a housing with a built-in deck roadway and butt nodes on the sides of the engine and the expectations which limited its application in floating bridges and ferries because of the possibility of spillage of the oncoming flow.

It is also known motor link (prototype - see patent Germany N 3045472, class B 63 B 35/36, E 01 D 15/14, 2.12.1982), comprising a housing with a built-in deck roadway, butt nodes on the sides and the rotary nasal and aft fairings, engine and propulsion and steering complex, placed in the enclosure.

The disadvantage of this motor link is also limited its application in floating bridges and ferries because of the possibility of spillage of the oncoming flow.

Object of the invention is the improvement of the motor link by eliminating the possibility of its being filled oncoming flow.

The solution of the stated problem is achieved in that the motor element containing pivotally interconnected average and two extreme pontoon with a built-in deck roadway, butt nodes on the sides and the rotary nasal fairings, engine and propulsion and steering complex, placed in the middle pontoon and installed on the deck of the cabin, winch and stand with bypass pulleys equipped with hydrodynamic shields, mounted by brackets on the nasal fairings can be rotated in a vertical plane relative to said kreido buildings pontoons and turned down the fairings.

Performed experiments showed that the application of hydrodynamic shields on the engine link increases its resistance to flow by 35 - 40%.

The invention is illustrated by drawings, which depict: Fig. 1 - motor link, side view; Fig. 2 is a plan; Fig. 3 is a view As in Fig. 2; Fig. 4 - section b-B in Fig. 2; Fig. 5 - section b-b of Fig. 3; Fig. 6 - section G-G in Fig. 3; Fig. 7 - section d-D in Fig. 3; Fig. 8 type E in Fig. 4; Fig. 9 - node I in Fig. 2; Fig. 10 - placement of hydrodynamic shield on the fairing before folding into the transport position of Fig. 11 - node II in Fig. 10 of Fig. 12 - section And in Fig. 11; Fig. 13 is a diagram of the rotation of the fairing with hydro shield to the transport position of Fig. 14 site III in Fig. 13.

Motor link contains the average pontoon 1 and connected by hinges and deck locks folding pontoon 2. In the case of the middle pontoon 1 posted by motor 3 and propulsion and steering complex 4, and is installed on the deck of the cabin 5, 6 hours with bypass pulleys and winches 7 with traction ropes. On the outer sides of the extreme pontoons 2 posted by butt sites, made in the form of a fork 8 with a rolling pin and lugs 9, as well as retaining the nodes 10 and the governmental fairings 11 and 12, and in the aft - reflecting shields 13. Turning fairings made in the form of triangular prisms and connected to the buildings of the pontoons by means of hinges 14 and flat pins 15. To the steering fairings fixed by means of the levers 16 and 17 can be rotated in a vertical plane and fixing in position of hydrodynamic shields 18 and 19. Levers channel section pivotally attached to the fairing by the axes 20 and are secured spring-loaded pins 21 within the holes 22 on the ends of the levers. In addition, on the upper surface of each arm completed the hole 23, and the bracket 24 and the hole 25. In the lower edges of the fairings made niches 26. Each hydrodynamic shield installed on the pontoons at an angle of approximately 45oto the incident flow. While the shields are connected to the levers 16 and 17 by means of pins 27 and fixed from rotation of the hinged sectors 28 segmental form, attached to the boards using two axes 29. In the middle part of each sector is set strap 30 with the grooves, and the upper part is spring-loaded hook 31, which hole lugs 32 adjacent the hinged sector and linking them together in a vertical position. While retaining strips 33, attached to R is Hydrodynamic shields middle and outer pontoons are interconnected by upper and lower edges with retractable pins 36, secured by screws 37.

Motor link in the transport (folded) position is transported overland by car.

The proposed device operates as follows. When assembling single floating bridges and ferries car with the engine link lead back to the water's edge, using the winches 7 and racks with 6 bypass pulleys rotate at the pontoons 2 relative to the average of the pontoon 1 in the lower position and unload the level of the water. Then raise the hydrodynamic shields 18 and 19 in the working position and place the motor link between pontoon links, connecting them to each other with forks 8 with movable pins and lugs 9. When this motor link set in single pontoon bridge or ferry hydrodynamic shields against incoming flow. After crossing the floating bridge or ferry dismantle and transfer motor link in the transport position. To do this by unscrewing the screws 37 and sliding the pins 36, sever hydrodynamic shields. Then lift up the spring-loaded hooks 31, take them out of the holes of the lugs 32, turn the sectors 28 relative to the axis 29 in a horizontal position and secured with spring-loaded hooks 31, introduce them to the hydrodynamic shields relative to the pins 27, stack them on top of the levers 16, 17 and fixed spring-loaded hooks 34, introducing them into the holes 23 of the levers. After all, pontoon arm, press the pin 21 and remove it from the hole 22, resulting in the shield together with the lever rotates downward about the axis 20 (Fig. 13 this position of the shield shown in phantom lines). Then the shield tight to the bottom edge of the fairing before sunset arm in the recess 26 of the fairing and secure the shield with the lever in this position, inserting the pin 21 into the hole 25 of the bracket 24. Next, push the flat pin 15 of niches fairing and fairing choose to unpin it from the hull of the pontoon. This fairing under the action of gravity will turn down (position F in Fig. 13). Drawn pontoon lever fairing until it touches the shield to the housing of the pontoon, fix the fairing using the whip device 10 (the position R in Fig. 13). After that load motor link on the car, zapasowa traction rope winches 7 to by-pass pulley racks 6 and placed at the pontoons in the middle of the pontoon.

In double floating bridges and ferries motor units are placed between the paired pontoon links in pairs, noses to each other. This hydrodynamic shields are lines which provide for the flow of protect-reflecting shields 13.

Motor link containing pivotally interconnected average and two extreme pontoon with a built-in deck roadway, butt nodes on the sides and the rotary nasal fairings, engine and propulsion and steering complex, placed in the middle pontoon, and installed on the deck of the cabin, winch and stand with bypass pulleys, characterized in that it is provided with a hydrodynamic shields, mounted by brackets on the nasal fairings can be rotated in a vertical plane on the said brackets and fixing in a predetermined position, in transport position the boards with brackets placed between the buildings of the pontoons and rotated to the lower position of the fairing.
