The invention relates to the field of shipbuilding, and, more specifically, to devices for launching ships, and can be used in hydraulic structures, for example, in the repair and modernization of the transverse slips.

A device for draining the vessel, which includes a slip for control of the descent of the vessel with the track on which are mounted with the possibility of forward movement of the horizontal and Kosyakova truck; and a traction winch (see Maenchen, Naukleros "ship-carrying equipment. Leningrad: Sudostroenie, 1977, figure 2). According to the similar vessel is delivered from the place of Assembly to slip on stacker trucks, straddles the horizontal trolley and then moves on Kosyakova truck, for subsequent descent of the vessel on the water.

The disadvantage of this known device is the complexity of the design and its consumption due to the presence of horizontal trucks, as well as Foundation for laying rails for horizontal movement of the trolleys, which leads to a considerable loss of the working area of the slip. Furthermore, the presence of horizontal trucks leads to a reduction of the allowable precipitation vessel or requires deepening waters and lengthening the inclined part of the slip.

It is also known a device for draining the vessel, which includes a slip with horizontal and inclined parts and, laid them on the track, on which are respectively mounted, with the possibility of progressive movements, berth and Kosyakova trucks, and towing winches. (See Maarten, Naukleros "ship-carrying equipment", Leningrad: Sudostroenie, 1977, Fig.6-7 - prototype).

By means of this known device transplant ship directly from stacker trucks on Kosyakova, while the stacker cart is moved into the space of the inclined part of the slip on the rails, laid on the foundations, the upper portions of which are located in the horizontal part of the slip.

The disadvantage of the prototype is that on the inclined part of the slip forming step, the height of which is required to lift spuskaemogo (raised) a vessel at Kosyakova trucks, which excludes the possibility of servicing heavy draft vessels or requires further deepening waters. In addition, the limited width serviced by the slip of the courts.

The technical result of the claimed invention is the enhanced operational capabilities of the slip by expanding the range of accepted characteristics of vessels (increasing precipitation and width), without the need for additional dredging.

This is achieved in a device for draining the vessel, which includes a slip with horizontal and nuklon the second parts, with laid them on the track, on which are respectively mounted with the possibility of forward movement berth and Kosyakova trucks with traction winch and the fact that the line of intersection of the horizontal and inclined parts mounted Foundation for rails projecting beyond the dimensions of the horizontal part of the slip), made in the form of a stabilizer that is mounted can be rotated from horizontal to inclined position, corresponding to the slope angle of the inclined part of the slip and back via the hinge mounted in a vertical plane passing through the line of intersection of the horizontal and inclined portions of the slip, while for rigid restraint in the horizontal plane balancer equipped with latches, mounted along said line of intersection of the horizontal and inclined portions of the slip.

This technical result is also achieved by the fact that the latches are interconnected rods and provided with a gear in the form of hydraulic jacks mounted on the ends of the slip.

In addition, this technical result is also achieved by the fact that each balancer is equipped with a ballast to hold the rocker in the off position.

Figure 1 shows a General view of the claimed device for lowering the vessel in the plan;

figure 2 - vessel mounted on a stacker cart is;

figure 3 - vessel transplanted on Kosyakova truck

The inventive device for lowering the vessel 1 includes a slip with 2 horizontal and inclined 3 pieces, laid them on the track 4 and 5 are respectively mounted with the possibility of forward movement berth 6 and Kosyakova 7 truck. To move the carriages 6 and 7, the device is equipped with a traction winch 8. Horizontal 2 and hatchback 3 parts of the slip intersect on a straight line 9 called axis zeros. Rails 4, near the line of intersection 9 2 horizontal and inclined 3 parts shipyard laid on the beams 11 with ballast cargo 10 and mounted for rotation from horizontal to inclined position corresponding to the corner of the inclined part of the slip 3, and back through the hinge 12 that is installed in the vertical plane passing through the line of intersection 9 2 horizontal and inclined 3 parts of the slip. For rigid restraint in the horizontal plane balancers 11 provided with latches 13, mounted along the line of intersection 9 2 horizontal and inclined 3 parts of the slip. The tabs 13 are made of well-known construction, for example, in the form of a horizontal valves are interconnected by rods 14 and provided with a gear in the form of hydraulic jacks 15 mounted on the ends of the slip. The hinge 12, which offers the wives in the vertical plane, passing through the axis zeros 9, transmits the vertical load from the stacker trucks 6 on the ground. In addition, the balancer 11 is equipped with brakes 16 to limit the movement of stacker trucks 6 on the edges of the beams 11.

For launching of the vessel 1 along the inclined portion 3 along the rails 5 raise Kosyakova truck 7 traction winch 8. At this point, the latches 13 does not hold the balancers 11 along the axis zeros 9, which under the action of the ballast 10 occupy an inclined position. At the same time carry out the transportation of the vessel 1 to the location Kosyakova trucks 7 on rails 4 horizontal part 2 berth trucks 6. By the time of delivery of the vessel 1 to the location Kosyakova trucks 7 beams 11 are installed in a horizontal position, rotate around the hinge 12, and secured by clamps 13 which move with the help of rod 14 by the hydraulic jacks 15, used to move the latch 13 in the direction necessary to keep the balancer 11 in a horizontal position. Then the vessel 1 is moved to berth trucks 6, combined with Kosyakova trolleys 7 and put them through lifts (not shown) stacker truck 6.

Then stacker truck 6 rolled with rails 4, located on the balancers 11, using a hydraulic Jack 15 latches 13 release of the ball is a Syrah 11 and the latter occupy an inclined position under the action of the ballast 10. After that the vessel 1 on Kosyakova trolleys 7 using traction winch 8 is lowered along the inclined portion 3 of the slip before the ascent.

The invention allows to significantly extend the operational capabilities of existing slips by expanding the range of accepted characteristics of vessels (increasing precipitation and width), without the need for additional dredging.
