The invention relates to shipbuilding and relates to devices for launching the vessel from shore building places, mostly located at high altitude above the water level or in the area of the large difference in water level in the reservoir.

Known various devices for launching the vessel, but not all of them can ensure the descent vessels from a great height, in particular dry and floating docks.

Known, for example, slips that can provide the boat with any height (see M. J. Atin, N. And. Chekletsov. "Ship-carrying equipment". L., "Shipbuilding", 1977, pp. 4-10). However, for shipyards with large height differences to the level of the water the length of the slip will be significant due to its relatively small angle, so the coastal area of this shipyard, which will be the track trigger trucks, would be unreasonably large. In addition, the track slips have the underwater part, and therefore for the construction of these facilities will be required to perform a large amount of underwater work, which will lead to their appreciation.

Vertical lifts with lifting platforms, suspended on the cable of the winch (see A. P. Grachev. "Salvaging facilities abroad." M., 1966, pp. 347-364), can provide the boat with any height, but with increasing elevation� lowering/lift vertical lift will increase demands on the strength of load-bearing walls/columns lift, will be complicated positioning system platform lift cable suspension at high altitude lowering. In addition, vertical lifts have at least one wall (the number of support columns installed in the waters of the reservoir, due to the implementation during the construction of the lift of a large amount of underwater work. In General, the lack of vertical lifts when used for the launching of vessels from a great height is their high price.

The closest to the claimed is a lift according to the invention of the USSR №1641700, which has a rotatable cargo platform is made of a submersible Ballesteros part with a concave cylindrical bearing surface and a flat portion connected tangentially to the cylindrical surface, and a pivot connected to the coastal wall. The ship on cargo trucks served on horizontally positioned dry part and then roll on the descending part with its simultaneous ballasting. When the rotation of the loading platform relative to the axis of the swivel truck with the ship rolled on a cylindrical surface with simultaneous descent. The disadvantage of the invention is limited altitude range in which the lift can be lowered/raised court, its failure to make the descent vessels with large heights� and/or when a significant water level fluctuations in the reservoir.

The object of the present invention is to expand the functionality of sudokusolver facilities that support the launching of vessels with horizontal building places.

The technical result provided by the invention, which solves this problem, is to improve the manufacturability of the descent vessels with horizontal construction locations with a large difference to the level of the water.

Said technical result is achieved when using the claimed stosunkowo facilities, including coastal wall, floating tank ballasting system and turntable mounted on the wall by a hinge with a horizontal axis of rotation and having a concave cylindrical bearing surface of the same radius of curvature, which has a wheeled transport cart. In addition, the structure contains at least two rows of platforms with parallel axes of rotation, spaced along the height of the coastal wall, wherein each platform is provided with a number of mechanisms for tilt, hedges, limit movement of the trolleys, and offset from the platforms of adjacent rows so that mutual rotation is located between the platforms these series, filleting into a single cylindrical surface, coastal STE�equipped ka niches, hosting the platform in their turn.

In the particular case of the regulation mechanisms of rotation of the platforms contain floating tanks that are installed on the platforms of the lower row, and the rod connecting each pair next to each other the platforms of two adjacent rows and having a pivot mounting at the free end of the upper platforms and moving the connection from bottom platforms.

The invention is illustrated in Fig.1÷3. Fig.1 shows stosunkowo structure of Fig.2 - rod device, connecting platform of two levels, Fig.3 - the sequence of the boat in the water with stosunkowo facilities.

Stosunkowo the construction includes several platforms 1, secured by means of cylindrical hinges 2 with a horizontal axis of rotation on the coastal wall 3. Platform 1 are located on several (at least two) levels of the coastal wall with a vertical offset relative to each other, and at each level can be from one to several platforms (number of levels, mainly depends on the height difference between the shore-built location and water level). Each platform 1 has a cylindrical support surface 4; wherein the bearing surface of all platforms have the same radii of curvature. Platforms of different levels are located along �Beregovoy wall so any platform when rotated around the hinge 2 and the way down was held between the platforms of the other levels. On all platforms of each level are transportation truck 5, is provided with wheels 6, resting on the cylindrical surface 4 platforms. The trolleys are free to roll on the supporting surface of the platform when turning and lowering the latter. Thus when lowering the platform overlying a number of their bearing surface mated in position with the bearing surfaces of the platforms nearest the lower row, which is in its upper position. The platform is equipped with mechanisms for tilt to control the speed of lifting/lowering and the possibility, if necessary, stop the process. To avoid vanishing trucks with platforms the latter is equipped with limiters that prevent displacement of the trolleys in the transverse direction (along the wall) and stopping the movement of carts at the free ends of platforms. In addition, trucks can be equipped with a braking system to prevent accidental, not required by the process of descent, movements. The upper support surface of the trolley on the platform of the top row, which is in its upper position, is flush with-built venue 7, which made the vessel 8.

Mechanical�we regulate the rotation of the platform around 1 joints 2 may be made, for example, as follows. The lower level platform fixed on the coastal wall near the water level of the water area 9 and is provided with a floating tanks (pontoons) 10 having a total buoyancy that can hold the total weight of the descent to the water vessel and platforms. The tank is provided with a ballasting system - valves for water inlet and a pump for pumping. All overlying platforms rely on the underlying rods 11, which are fixed at the free end overlying platforms hinges 12 and movably connected with the underlying platform, for example, using the wheeled carriages 13 moving along the cylindrical surface of these platforms and having the drive motors and brake system.

Coastal wall has niches 14 in which are the platforms when they turn and exit.

Descent vessels is performed as follows. Vessel 8, is made on the site 7, is moved by any known method (for ship-carrying rail trucks, trailers, etc.) in the transverse direction (side to stosunkowo construction) on the upper surface of the trolleys 5 the top row of platforms, which in its extreme upper position, and transplanted to a stationary support (keel blocks, cells, etc.) trucks; after that, the vehicle is returned on the place. In the process pyo�of Emesene vessel stosunkowo the construction of the lower platform are in a floating state (from tank 10 is pumped out the water), all overlying platform is located in its uppermost position, based on the coming of the underlying platform rods 11, the carriage 13 which is fixed in place, their braking system. After placing the vessel on the platforms of the upper row release brake carriages rods connecting the upper platform and the platform of the second row; the carriage is restrained by the brake system, begin to move on the cylindrical surfaces of the underlying platforms, with the free ends of the upper platforms are beginning to fall, the platforms themselves - to turn around the hinges 2, and truck 5 with the vessel 8 is rolled on the platforms to the far edge and simultaneously lowered. When the cylindrical support surface 4 of the upper platforms and platforms of the second row will be aligned, and accordingly, align the upper surface of the trolley first and second row, the hull will enter into interaction with the supports in carts platforms second row. After that, the brakes are released carriages rods connecting platform of the second and third level from the top. There is turning and lowering of the platform of the second level to match their bearing surfaces with the surfaces of the platforms of third-level. The upper platform is moved over the rod to the side and prop trucks top platforms out of contact with the hull; pic�ednie thus grafted onto the truck platform of the second level. The process is repeated until the sinking of the ship on truck lower platforms. After that, the tank bottom platforms filled with water, and the platform is submerged in water until the ascent of the vessel. When turning and lowering the platforms they're leaving in 14 niches in the coastal wall 3.

Following the withdrawal of the vessel from stosunkowo the buildings of the last return to the starting position. This pumped water from the tank 10 to the ascent of the lower platforms in their upper position. Then raise upwards overlying the platform by moving the carriage and the rods connecting the upper platform with the underlying, on the cylindrical surface of the underlying platforms with drives carriages.
