The invention relates to hydraulic equipment for building and repairing ships, and concerns the design of devices for lifting and lowering ships using slip.

The purpose of the invention is to increase the area of the berths.

FIG. 1 shows the device, top view; in fig. 2 is a diagram of horizontal and inclined paths, view. from above; in fig. 3 - device for transfer carts, horizontal section; in fig. 4 - the same, for braid carts, horizontal section; in fig. 5 - stapling tracked truck, front view; in fig. 6 - the same, top view; in fig. 7 - caterpillar of the dock carriage, longitudinal section; in fig. 8 is a section A-A in FIG. 7

The device for lifting and lowering ships consists of ship-boring truck trolleys 1, located on inclined sline tracks x 2, laid on parallel ledges 3, an oblique transfer comb (in the upper part of inclined tracks), including oblique projections 4, elevated above the oblique horizontal projections 5, winches 6 for lifting and lowering skid carts, as well as interchange routes 7 with oblique intersections 8, retractable tracks 9, slip ways 10 with rectangular intersections And and ship transport carts 12 for horizontal movement of the vessel before transfer to the sliding and then to the berth carts. Structurally and functionally interchangeable, sliding and stacker carts are the same and represent the stacker carts of the transverse comb slip.

The device in the area of horizontal movement of the vessel after skidding carts includes bespolka nymplana ship carts equipped with suspension supports 13, caterpillars 14 on barrel hollow hubs 15 arranged in pairs and mutually perpendicular to one another, and gear 16 mounted on rotating axles 17 bypass cages 18, on which are placed the rollers 19, ensuring the rotation of the hubs one in the other pair.

All tracks are represented as longitudinal pneumatic tires, instead of which you can use, for example, rigid tracks in the form of arched plates between the links of two Gall chains mounted on the rim of hollow hollow hubs.

The cargo platform 20 of each bogie is mounted on supporting trunnions and equipped with a lift 2 for keeping the vessel in motion, at an elevated position at a constant height from the top of the loading platform, with two power units for driving caterpillars consisting of two reversible engines 22, gears 23,

brakes 24 and two tracked propulsion units from a power transmission, including two cardan shafts 25, connected to axles 26 and conical scabies 27. To retract the position of the trolley, extendable support 28..

The device works as follows.

Trolleys set in the underwater

position on parallel sloping

Put x 2, having a slope of 1: 8-1: 6 to the horizon and located on the ledges 3 in the coastal slope with a slope of 1: 6-1: 4.

Floating on the water and to be lifted up, they lead to the platforms of the shipboard truck trolleys and simultaneously lift the trolleys with the vessel, moving the trolley along inclined tracks with the help of winches 6 located on a horizontal platform between interchange tracks 7 with intersections 8, in the extreme upper position of the inclined paths on the ledges 4.

The transfer of the vessel on ways 9 and 10 is carried out by rolling under the vessel of empty ship berths carrying the sliding and berth tracks. The transfer of a vessel on a horizontal platform using linear-free direct-over ship carriages of the unidirectional movement is carried out in the area of the oblique transfer comb by mixing, in terms of the axes of the supports 13, parallel to the direction of the lifting tracks. The desired orientation of the positioning of the axles of the supports 13 is obtained thanks to the appropriate arrangement of the tracks 14 moving along the road surface on the road;

The omnidirectional movement of the carriage is ensured by the possibility of simultaneous operation of two electric motors whose 22., which drive each caterpillar into the rotational motion, and rotate relative to intersecting longitudinal

axes.

Correction of the direction of movement of the carts is performed by turning them relative to the supports 28 located under the load platform.

The rotation of each engine 22 is stopped by disconnecting the power supply and the brake device 24.

To ensure synchronism of movement and change the direction of movement of a set of direct trucks, controlling them

movement while moving the vessel is performed from a single mobile console.
