The invention relates to shipbuilding, in particular to ship repair, in particular to the installation of bulk sections on the stocks.

The purpose of the invention is to simplify the design and expand the technological possibilities by allowing it to be tilted and moved in any plane.

Figure 1 shows the device, a general view; figure 2 - view And figure 1

The device for repairing ship hulls using the sectional method consists of railing rails 1 with a winch 2, tap-off units 3 and cables 4 interacting with a trolley made in the form of a bath 5 with runners 6 interacting with the railing 1. Inside the bath 5 at the bottom in the middle a cylindrical collar 7 is mounted, and water 8 is poured into the bath, on the surface of which a cylindrical float floats, made in the form of a platform 9 with three degrees of freedom. In the upper part of the platform 9, four brackets 10 are fixed, on which self-centering dock supports 11 are mounted with individual elevator drives 12. On the side surfaces of the platform 9, latches 13 are installed, which cooperate with locking elements 14 mounted on the opposite sides 15 of the bath 5. A section 16 is installed on the trolley for transporting it to the place of installation in the ship’s hull 17.

 The device works as follows.

Section 16 is mounted by a crane (not shown) on self-centering dock supports J mounted on brackets 10. Then platform 9 is lowered down, displaces water 8 poured into the bathtub 5 of the trolley, but remains afloat and fixed relative to the bath 5 by retainers 13 through the locking elements 14 mounted on the opposite sides 15 of the bath 5 Then the device along the rails 1 on the skid x 6 with the help of the winch 2 and the tap-off units 3 with the cables 4, interacting with the trolley, is moved with section 16 to the place of installation in the ship's hull 17. Then

raise the self-centering dock supports 11 by individual drives of their lift 12 until the minimum clearance between section 16 and the housing 17 is reached. The fixers 13 release from the locking elements 14. Then the orientation of the section 16 is manually set in the horizontal plane

two mutually perpendicular directions and rotate it around its axis within the gap between the cylindrical collar 7 and platform 9, and thereby orient the position of the section

16 relative to the installation location in. hull 17 of the vessel.

After that, the drives 12 for lifting the self-centering dock supports 11 are turned on and lift them together with section 16 upwards. With the individual size of the lift, each manipulator: Tsoi from the self-centering dock supports 11, reaches the necessary roll and trim in any plane.
