Method for lifting vessel to horizontal slipway-deck

FIELD: transportation.

SUBSTANCE: method is proposed for lifting a vessel to the horizontal slipway-deck, where the vessel is directed to the salvage equipment with the ship-carrying equipment mounted thereon, then the ship-carrying equipment moves the vessel to the horizontal slipway-deck, wherein the pneumatic roller-bags are used as a ship-carrying equipment, and a barge of the required size is used as a salvage equipment, which is moored to the pier by its nose before directing the vessel to the salvage equipment, and the stern is drowned till the barge stern is on the ground, the barge is ballasted on an even keel after directing the vessel to the salvage equipment, and then the barge, with the ship-carrying equipment mounted thereon, on which the vessel is located, is transported to the pier of the horizontal slipway-deck.

EFFECT: method for lifting a vessel simplifies the vessel lifting to the horizontal slipway-deck, because it does not require construction of an additional salvage device with rail oblique ways including surface and underwater areas.

FIELD: construction.

SUBSTANCE: ship-raising construction includes a ship-carrying trolley, precast reinforced concrete slabs, a ship-carrying track with inclined and horizontal platforms and is equipped with a metal rack for placement and movement of precast reinforced concrete slabs along it in process of construction erection. The metal rack is made in the form of a metal frame including bearing metal beams with rigidly fixed retaining planks, which form an inclined guiding upper belt /IGUB/ with higher and lower sides, at the same time the higher side of IGUB is installed closely to the coastal ledge, and the lower side is installed with a support to the underwater coastal slope, at its end there is a support of the end block rigidly fixed with the end wall. L-shaped brackets are fixed to the lower side of each precast reinforced concrete slab. In the middle part of each reinforced concrete slab there is a hole for supply of concrete mix. Also the method is proposed to erect a ship-raising construction.

EFFECT: increased resistance of a ship-raising construction to erosion and abrasive effect of drifts.

FIELD: transport.

SUBSTANCE: ship launching device incorporates a shipway with a horizontal and inclined parts accommodating tracks supporting translating dock and slipway trolleys and towing winches. The rail foundation is arranged on the line of intersection of the shipway horizontal and inclined parts, extending beyond the horizontal part and representing a balance member mounted to come from the horizontal into inclined position corresponding to that of the shipway inclination angle and vice versa, thanks to the rotating joint fitted in the vertical plane crossing the line of intersection of the shipway horizontal and inclined parts. For the balance member to be fixed in horizontal position, it is furnished with stops arranged along the aforesaid line of intersection between the shipway horizontal and inclined parts.

EFFECT: expanded shipway performances.

FIELD: shipbuilding; device for off-slipway transportation of trans-border trolleys loaded with block-sections of ship's hull to launching position during building of ships on building berth lines.

SUBSTANCE: proposed system is provided with mechanism for motion of block-sections along building berth; this mechanism is provided with building berth trolley with cable winch mechanism for motion along rail track of building berth and mechanism for motion of block-sections from slipway to building berth. Mechanism for motion of block-sections along building berth and mechanism for motion of block-sections from slipway to berthing berth are made in form of single system provided with trans-border trolleys equipped with unified cable winch mechanism for motion of them along rail tracks. These rail tracks have at least two horizontal longitudinal branches, slipway branch and transversal branch intersecting them. Cable winch mechanisms are located on longitudinal rail tracks for motion of trolleys over horizontal section of rail tracks of longitudinal and transversal branches and slipway branch; two cable winch mechanisms of mirror arrangement are simultaneously used for motion of trolleys over inclined section of slipway branch whose haulage ropes are provided with two-fold tackle blocks and balancing cross-piece secured on trolley through tie rods.

EFFECT: increased cargo capacity of system; extended range of technological capabilities.

Launching complex // 2313468

FIELD: shipbuilding; ship launching complexes.

SUBSTANCE: proposed launching complex has slip for ship mounted on its supports made in form of launching trolleys with technological pads mounted on them. CG of support areas and ship's CG are located in one vertical plane of slip which is perpendicular to ship's BL. Heights of technological pads are determined from the following formula: hi= hmin + Vi, where hi is height of technological pad; hmin is minimum height of technological pad, constant for all supports; Vi is height of varying part of technological pad equal to sag of each support selected from calculation of total strength of ship placed on two rigid supports under action of distributed weight loading of ship equalized by reaction forces in sections of slip intermediate supports.

EFFECT: extended operational capabilities of launching complex without its updating at retained local and total strength.
