(54) SHIP LIFT

This invention relates to shipbuilding, ship repair. There is a well-known super-lifting structure for transplanting ships from the water to the shore using a ballast pontoon equipped with a rail track for the carriage l. The disadvantage of this device is that the pontoon is jammed when a roll or trim is formed. The closest technical solution to the invention is a ship lift, containing a pontoon with rail tracks, connected by frame pillars, with the strength of the ball joints with supports located outside the reservoir | 2}. The well-known ship elevator has the following disadvantages: the large mass and complexity of the effort of the foam; the need for admission and ochkach1I ball Utah; the need for a large depth of water near the coast, equal to the sum of the seam with the reserve for ascent, the height of the platform with the rails and the height of the platform; the difficulty of remigue pontoon. The aim of the invention is to save in construction and operation. The goal is achieved by the fact that the pontoon contains two longitudinal beams connected by two transverse beams, moreover to longitudinal beams, n (No. of fixed elastic inflatable tanks made of waterproof fabric. In Fig. 1 the proposed boom box is shown; however, A-A in Fig. I, in Fig. 3, node I in Fig. 2 in Fig. 4 is a view along arrow B in Fig. 1, and Fig. 5 is a diagram of the air duct.Ship lift consists of two longitudinal beams 1 box section, rail tracks 2 are laid on KOTOpt ix. The beams are interconnected by cross beams 3 with the help of b ltovyh compounds 4. The transverse beam with poMoschyusharnirov 5 are connected to the frame

by the supports 6, which are connected with supports 8 by means of the hinge 7, located at the bottom i of the reservoir. To the lower buttocks of the longitudinal box-like 6-pok.1 elastic elastic inflatable containers 9 nz of waterproof fabrics are fastened.

The pontoons have studs 10 for attachment to the sandwich shelves of co {{ebechaty beams) and fitting 11 for connecting the air duct.

Ship lifts are kept from shifting at the coastal wall by centering bats 12 and mooring winches 13. On the shore are ustashaevs repulsive CTpeJSbi 14. On the longitudinal beams 1 air 15 are located, having orpoctsH for connecting with pipes, leading to 1 "tuz am 11 pontoons.

Oi of the sewer collector, a pipe 16 is laid to the coastal end, from which a flexible hose .17 goes to the shore, connect 5Yi with the help of a three oats -o crane 18, which can connect the suction lift air duct with a source of compressed air - the coastal air line or the atmosphere.

The ship lift works as follows.

The crane 18 is set in such a manner that it is possible to fill it with air. The longitudinal beams are in the same position. The rail tracks on the beams are centered with the rail tracks on the shore with the help of the teeth 12, the beams are attracted and fixed by mooring winches 13.

The vessel on the carts rolled from the shore to the ship elevator. After mooring winches, after removing the mooring ends from the longitudinal beams, the repulsive booms 14 are in motion and simultaneously the crane 18 connects the elevator air line to the atmosphere, nepfsppbiB, air access from the main lines.

Under the action of the mass of the vessel and the beams of the ship elevator and the hydrostatic and ampli fi ber air is displaced from the pontoons.

By reducing their volume, the ship is launched into the water until it is ascending. A safe descent speed is established by the appropriate selection of pipe sections of the elevator of the ship elevator or by applying throttling devices regulating the speed of the air outlet (inlet) from the pontoons.

Lifting of the ship is performed in reverse

order

The ship is guided onto a submerged ship elevator with trolleys, orienting along signal poles that can be mounted on ship lifting rails. Crane 18 open air access from the coastal line to the air duct. Air-inflating pontoons increase their volume - buoyancy forces arise and increase,

ship lifter with a ship floats to the top position. With the help of mooring heads 13, the longitudinal beams are attracted before joining rail by beams with coastal tracks, after

what the ship is moving from the ship to the shore.

invention formula

A ship elevator containing an articulated poigon, connected by frame struts by means of hinges with supports located at the bottom of a reservoir, is characterized in that in order to save on construction and operation, the pontoon contains two longitudinal beams connected by two transverse beams, and to the longitudinal beams, attached elastic inflatable containers made of waterproof fabric.
