Description

The invention relates to devices primarily used for receiving ships from the shore and launching on water, as well as for lifting ships from the water and transferring them to shore.

The purpose of the invention is the expansion of operational capabilities ..

In FIG. 1 schematically shows a gear elevator, side view; in FIG. 2 - the same, gran; in FIG. 3 section A-A in FIG. 1.

ί The transmission boat elevator contains a ballastable main pontoon 1 and side towers 2. On the slipway deck of the main pontoon 1, the lever sockets 3 are pivotally fixed with lower bases, the upper bases of which are pivotally fixed in the bottom of the additional pontoon — flyover 4.

ί On the rail deck of the pontoon — esta ™ CADA 4 there are rail tracks 5 for longitudinal movement of the vessel and rail tracks 6 for transverse movement of the vessel, joined with the rail ™ by separate tracks 7 and 8 of the coastal station 9, in the inner sides of the towers. 2, niches (not shown) are made in which rotary crowns ™ ШТ 'CADs 4 are installed in the upper position. Deck 11 is made in the tower (towers) at the level of the rail deck of the pontoon flyover above this deck. It is made up of separate rectangular volumetric sections 12, consisting of folding frames containing deck 13, levers 14 and hinges 15, fitted with durable flexible gas-tight material (material not shown). The internal cavity of each section 12 is connected by an air pipe 16 to a certain ballast compartment of the main aircraft 10 to support the pontoon esta ™ at its highest position, and part ts of the pontoon 1.

Section 16 is filled with air through pipe 16 — a spirit displaced from the ballast compartment by water when the pontoon 1 is submerged, and when water is pumped out of the ballast compartment (during ascent), air enters from the section through pipe 16 into the 50 ballast compartment. When the air is removed, the section is folded, 'reducing its height, when filling with air, the section increases in height, while maintaining overall dimensions in plan. 55 The volume corresponding to each section of the ballast compartment is adopted of a certain size, providing pressure in the section sufficient to increase its height and maintain its stable shape, providing the necessary buoyancy and stability · of the ship elevator in the submerged position.

On the deck 11 of the tower between sections 12, rail tracks 17 are installed, which are joined with rail tracks 7 of the coastal slipway and rail tracks 6 of the pontoon-flyover 4.

Transfer ship elevator operates as follows.

A ship hoist with a pontoon-flyover 4 in the upper position is mounted on supports 18 at the shore berth 9 and the transverse 'rail ways 6 of the pontoon-flyover 4 with rail tracks 7 are joined for transverse movement of the vessel on the shore berth 9 (Fig. 2). In FIG. 2 also shows the docking of the longitudinal rail tracks 5 with the rail tracks. 8 for the longitudinal movement of the vessel. This arrangement of coastal slipways (especially in shipyards) is possible.

I

Then, on slipway bogies 19, the vessel 20 is moved from the coastal slipway along the rail tracks 6, 7 to the pontoon overpass. At the same time, sections of 12 towers are in a folded state (with a height equal to the height of slipway bogies) below the level of the bottom of the vessel passing above them. Part of the ballast is removed from the pontoon 1, - 'and the surfaced · ship elevator with vessel 20 is transferred to the foundation pit for immersion; ballast the pontoon 1, and then the pontoon flyover 4. When ballasting, air is displaced from the ballast compartments through pipes 16 in section 12 of tower 2 and _ as the elevator plunges, sections 12 increase their height and volume, "which, when completely immersed, 1 provide the necessary buoyancy and stability of the lift in the submerged state. The floating vessel 20 is led out in the longitudinal direction. The ballast is pumped out of the pontoon estacade and the pontoon overpass is fixed after its ascent on the swivel arms 10.
