The invention relates to the field of shipbuilding, namely, river vessels, in particular to a self-propelled floating means, such as a ferry terminal Shuttle for transportation via rivers, canals vehicles, agricultural machinery, livestock and passengers.

Known for the design of river crossings containing steam to host remote control and dynamic drive its movement through troubleclef device for guiding a rope stretched across the river and secured on its banks (see A.S. USSR № 1073153, M CL 63 In 35/54, 1984, bull. No. 6).

The disadvantages of this are the counterpart poor performance on the shipping, which is entirely dependent on the flow rate (which is driven by ferry) and the speed and direction of the wind. This ferry is not effective when working in waters with low flow of the river. In addition, it is not adapted to work in winter conditions and weather with strong winds, because the windage ferry with located on the cargo hinders its movement.

The closest technical solution, selected as a prototype, is a river cableway containing vessels placed on them rollers, an electric motor connected through a clutch with gear, moving on to the rope (see A.S. USSR № 1428658, M CL 63 In 35/54, 1988 the., bull. No. 37).

The main important shortcomings of the prototype are low capacity vessels (ferries), as to power the motor energy is required diesel generator with fuel for its extra size of the cargo area, as well as low traction caused by the low coefficient of friction with a small square clutch rollers with traction rope that makes the ferry ineffective, in addition, poor visibility berth in the process of mooring operations.

The aim of the invention is to increase the capacity of the ferry and its performance by increasing traction by increasing the coefficient of friction and the establishment of a ferry enhanced view of the working area of the pier.

This goal is achieved by the fact that to increase the cargo capacity of the ferry it is equipped with pantographs, interacting with catenary wires stretched over the river by means of supports, and to increase the efficiency of the ferry it drives the cable driving pulley or drum, interacting with covering the traction rope. To improve visibility of the working area of the pier for mooring operations on the ferry on the deck of the superstructure made cutting with the attached equipment.

Comparative analysis with the prototype of the om shows what is claimed steam-ship differs in that it is equipped with pantographs, interacting with catenary wires stretched over the river by means of supports and supply energy to the motor that drives the cable driving pulley, interacting with covering the rope, as well as the ferry made cutting with the attached equipment.

Thus, the claimed steam-ship complies with the criteria of the invention of “novelty.”

A comparison of the claimed solution is not only the prototype, but also with other technical solutions in this field of technology is not allowed to reveal in them the features distinguishing the claimed solution to the prototype that allows to conclude that the criterion of “substantial differences”.

The set of essential features specified in the invention directly affect the technical result in the achievement of the objectives of the invention. Thus, between the new set of essential features (with respect to the selected prototype) and achieved technical result is the existence of a causal link, which points to conform to the technical solution of the criterion of “inventive step”.

Industrial applicability of the claimed device is characterized by the possibility of the Yu of carrying out the invention in practice (i.e. using the entire set of features with known for the realization of this goal) to obtain the above specific technical effect.

The ferry consists of a pontoon 1 (1, 3), along flanges on the brackets 2 (3, 6) installed obnosy 3 (2, 5), which, on the starboard side fixed roller 4 (5, 6) rope 5 (1, 2, 5, 7). On the ferry in the area of the fore and aft ends installed ramps 6 (1, 2) to conduct cargo operations (entry and exit of vehicles, agricultural machinery). On the main deck of the pontoon 1 are add-in which is placed from the left side space 7 (Fig 1, 3) to shelter passengers in inclement weather and in winter, and with the right Board - ready room 8 (1, 3) for the crew. On the deck of the superstructure 8 made cutting 9 (1, 3, 4), equipped with a remote control 10 (4) of the drive control.

The actuator includes a shaft 11 (figure 5) single steel lined with rubber rope-guiding the Kiva 12 (figure 5, 6)supported by bearings 13 (figure 5, 6)that is driven in rotation by an electric motor 14 (figure 5) through the clutch 15 (figure 5), the gear 16 (figure 5) and the second clutch 17 (figure 5), the clutch 15 is equipped with a brake pulley, which operates dvukhchastotnyi brake 18 (figure 5). The angle of circumference of the cable driving pulley 12 of the traction rope 5 (Fig.7) is 360°. On the deck of the wheelhouse 9 mounted pantographs 19 (1, 2, 3)interacting with catenary wires 20 (1, 2), stretched over the river by means of supports 21 (figure 1) at a height that provides the navigation of the river.

Steam works as follows. Upon completion of the loading of vehicles and passengers on the ferry up the ramp 6 (1, 2). After unmooring ferry from the dock with remote control 10 (figure 4), located in the wheelhouse 9 (1, 3, 4), is supplied with electricity by means of current collectors 19 (1, 2, 3) from the catenary wires 20 (1, 2) to the motor 14 (figure 5), which is connected to the network using the adjustable resistance (rheostat), and depending on the magnitude of the resistance included in the circuit of the motor is the rotor. The rotation of the rotor of the electric motor 14 is transmitted to the cable driving pulley 12 (figure 5, 6) by a coupling 15 (figure 5), the gear 16 (figure 5) and the second clutch 17 (figure 5). During the rotation of the cable driving pulley 12 with the angle of circumference of the traction rope 5 (1, 5, 7)360° is the traction force of the friction clutch arising between the traction rope 5 and the surface of the stream of the cable driving pulley 12. Due to the traction forces caused by rotation of the cable driving pulley 12, a ferry picks up speed, moving through the rope 5, zapisannomu in the rollers 4 (5, 6). When you approach the ferry to berth mooring operations are carried out by the braking of the rotor of the electric motor 14 through the brake pulley clutch 15 (figure 5) dvukhchastotnym brake 18 (figure 5). After mooring and after installation of the ramp 6 on the pier in the working position, the unloading and loading of vehicles, disembarking and embarking passengers. At the end of the loading on the ferry up the ramp 6 and after unmooring ferry on the rope 5 is moved to the opposite shore. The process of inclusion and the drive control of the movement of the ferry similar to the above, except in this case, the fact that the motor 14 is switched on for operation in the reverse mode (protivobloshinye).

The inventive steam-ship due to the presence of equipment, through which the feeding motor energy from catenary wires stretched over the river, allows you to increase carrying capacity, and the cable driving pulley provides a high coefficient of friction due to the increase of area and adhesion between the covering of the traction rope and the surface of the stream cable driving pulley, when this steam is easier to manage with its high maneuverability, and also in the presence of an elevated deck on the ferry has improved overview of the dock that allows you to prevent accidents during mooring operations. Thus, the use of the claimed invention will significantly improve the techno-economic characteristics of the ferry.

Steam-ship, containing the pontoon posted on the rollers, an electric motor connected through a clutch with gear, moving on to the rope, wherein the actuator is equipped with a device to allow movement of the ferry, made in the form of the cable driving pulley lined rubber and interacting with covering the rope, and the power drive is current collectors from the catenary wires, installed at a height that provides the navigation of the river.
