This invention relates to shipbuilding.

Known dry LT, OK, containing scaffolding and lifting device of the transport lifting complex for supplying the hull units to the dry dock with a cable-hook grab, including an overhead crane with cargo carts, mounted on a stationary spatial support 1.

The disadvantages of the known device are the large construction cost, and the installation of the g () horn () st (; one of the intersecting gantry crane and crane runways 6o, 4biiioii), as well as the fact that the crane bridge and crane bridge are equipped: Tolezhsk on the bridge across the dock chambers1,1;: g provide optimal usuyu g-; ropleskie blocks of the hull of the vessel, (tlichakmsch: -,., and, mom and medium vessels large dmio; that may require paired work two gantry cranes.

The aim of the invention is to reduce the cost of building a dry dock by simplifying the design and installation of a lifting device for feeding the hull blocks.

This goal is achieved in that a dry dock containing scaffolding and a lifting device of a transport and lifting complex for feeding blocks; ship hull in dry dock with cable-hook grab, including an overhead crane with cargo carts installed at the end of the dock chamber on a stationary spatial support, is made with installation of a stationary spatial support directly on the bottom of the dry dock, while it is jammed by the dock walls.

The crane bridge with cargo carriages is located along the dock, and the scaffolding is embedded in the stationary spatial support, in which openings are made for the passage through the Rus of these forests.

FIG. 1 shows a general view of the device, a plan; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

A cargo handling device (a lot of the dry dock complex consists of a chassis bridge 1, located along dock chamber 2, two cargo carts 3, moving along bridge 1 along dock bay

the chamber 2, and the spatial fixed support 4, mounted by the uprights 5 on the bottom of the dock chamber 6 and stuck to provide lateral stability by the walls of the dock chamber 7. Longitudinal stability

the supports are provided by braces 8, installed with a slight elevation above the dock walls in order to provide access for side gantry cranes for servicing when the ship's bow is completed, if it is in the area of cargo lifting device. In order to avoid the loss of the useful Nrzhina of the dock chamber, in 1 support structures at the walls of the dock are built in: Sca 9, and in the body of the uprights 5 and braces 8 provide | ) e11y proyem 1 O dl for passes through the Rus forest.

Dry dock with a lifting complex works as follows.

Filed from pre-platform 11 on a movable support 12 in the zone-action

lifting device b, Lok 13 cor; The vessel’s position is lifted by the device from the support 12 and after returning it to its original position, it is lowered to the bottom of the dock chamber 6 on the previously prepared ship-carrying carts 14 and then moved to

the side of the dock head for docking to the assembled part of the hull 15.

For attaching the vessel hull block before lifting, the crane bridge is installed along the axis of the dock chamber (keel track), and the cargo carriages on the bridge are tuned to the length of the line.

Technical and economic advantages

the proposed dry dock are

in simplifying the design, installing a cushioned device and cheapening it

construction and operation.

Claims (3)
