Abstract

METHOD OF SUPPLYING THE CASE OF THE SHIP OF THE SHIP WITH THE PREDODOKOVA SITE IN THE DRY DOCK, in which the ship's hull unit on the ship-carrying carts is fed into the ship dock installed in the dock and lowered onto the bottom of the dock, characterized in that The landing platform horizontally rolls onto the receiving mobile support mounted on the undercarriage at the butt end directly on its bottom, and moves said support with the ship hull block under the bridge lift crane, moving On the upper supporting structure, and then lifting the vessel hull block with this crane, remove the receiving movable support to the initial position and lower this block onto the dock ship carrier bogies. f 16 II II 11 I

Description

The invention relates to shipbuilding and can be used in the block construction of ships at the dry docks, equipped with relatively small lifting cranes.

Closest to the invention is a method for delivering a ship hull unit from a pre-dock platform to a dry dock, in which the ship hull unit on ship-carrying carts is fed to a ship elevator installed in the dock and lowered onto the bottom of the dock 1.

The known method is characterized by insufficient economics due to the complexity of the device and the need to build a track with rail tracks on the pre-dock site, the bottom of which must have a level mark the same as the bottom of the dry dock.

The purpose of the invention is to increase the efficiency of work on the equipment of the pre-dock site and the flow of ship blocks from it into dry dock.

The goal is achieved according to the method of supplying the ship hull unit from the dock to dry dock, in which the ship hull unit on ship-carrying carts is delivered to the ship dock installed in the dock and the ship's dock unit horizontally rolls onto the receiving dock at the bottom of the dock. a movable support mounted on the undercarriage at the butt end of the dock directly on its bottom, and the said support is moved from the vessel hull block under the overhead crane of the ship elevator, which is moved along the upper support console ruktsii and then lifted by this crane unit hull, outputting a receiving movable support into position and lowered to dock ship-block carriage.

FIG. 1 depicts a transport and lifting complex of a dry dock and a landing site, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows the node I in FIG. 2; in fig. 4-7 - section bb in fig. 1 in various positions of the vessel block in the implementation of the proposed method.

The method is carried out as follows.

The hull block 1 of the vessel, installed by means of the hook girders 2 on the ship carts 3, is rolled from the anchor platform 4 onto the spatial support 5 mounted on the bottom 6 of the dock by means of carriages 7 butt against the end wall 8 of the dock 9, which are joined to the rails 10 on the substructure 11 (FIG. 1). After rolling the ship's block onto the support 5, it, together with the ship's block 1, along the rails 10, laid on the bottom 6 of the dock, moves forward under the load trolleys of the load-lifting device 12, taken as a traveling crane on the upper supporting structure of the bridge crane (Fig. 5).

The attachment of the ship’s unit by rope-hooks is carried out by a known method, having previously installed

0 of the crane along the keel track axis of the dock, and the cargo carriages on the bridge are at the required distance L between them for securing the distance L. Then the hull block 1 of the vessel is lifted by a lifting device 12

From the support 5, together with the subrack beams 2 pre-attached to its bottom (Fig. 6) and after returning the support 5 from the carrier carts 3 to the initial position, it is lowered onto the bottom of the dock with its subilli beams 2 installed on the Q the previously installed ship-carrying carts 13 (Fig .7).

The technical and economic advantage of the proposed method as compared with the prototype consists mainly in reducing the capital costs of building the pre-dock site and improving the operating conditions of the dry dock while the ship’s blocks from the pre-dock site are being fed into it.

In addition, it is possible to remove the receiving support from the dock if necessary.

0 using the entire length of the dock for the construction of the vessel, with the latter closing. The ship hull unit forms directly in the docking section method using the available dock crane means.

METHOD FOR SUBMITTING A SHIP BOARD BLOCK FROM AN ANTHOURGE AREA IN A DRY DOCK, in which the ship's hull block on ship trolleys is fed into the ship elevator installed in the dock and lowered onto the bottom of the dock, characterized in that, in order to increase the cost-effectiveness of the work, the hull of the ship's hull with the pre-dock area is horizontally rolled onto a receiving movable support mounted on the undercarriage at the end of the dock directly on its bottom, and the indicated support with the ship’s hull block is moved under the bridge crane of the ship elevator, moved along the upper supporting structure, and then lift the hull block of the vessel with this crane, bring the receiving movable support to its original position, and lower this block onto the docking carts. / H Figure 1
