Description

The invention relates to lifting equipment, in particular, to systems for lifting sunken submarines.

A known system for lifting sunken submarines, including lifting butts and axles for guide slings mounted on a submarine, and a lifting device containing a bracket, pin, casing, which houses a spring-loaded screw that interacts with the pin and nut, slider, butt, mounted on the bracket for the guide cable [1].

The disadvantage of the lifting device are large dimensions, which do not allow to place it between the frames around the butt.

A known system for lifting sunken submarines, including lifting heads, mounted on a submarine, and a lifting device containing eyelets interconnected by an axis, a hook with a spring-loaded latch, connected by an axis to the lower eye, lifting brackets attached to the upper eyelet, a device for cocking the hook and locking it in the cocked position, consisting of a folding bar attached with an axis to the hook and blocking the hole in the tip of the hook, spring-loaded lever abutting I am at the lower end of the rail, and attached to the end of the latch of the control cable passed through the lugs on the body of the hook, and a device for securing the hook in the lifting butt made in the form of a wire guide attached to the end of the hook and inserted in the hole of the lifting butt on the sunken submarine ( copyright certificate number 1654125) [2].

The lifting device of the above system is more compact and allows it to be placed between the frames. However, the kinematics of the movement of the lifting device during the docking, in which there is no clear position of the lifting device relative to the butt, makes the docking process rather complicated and time consuming, especially when the sea is rough.

The objective of the invention is to improve the conditions of the docking of the lifting device with the butt on the submarine.

The task is solved by the fact that in a known system, including lifting butts installed on a submarine, and a lifting device containing eyelets interconnected by an axis, a hook with a spring-loaded latch connected by an axis to the lower eye, lifting the brackets attached to the upper eyelet on equal distance from the longitudinal axial line of the lifting butts on the submarine are installed docking nodes (axles) for guide conductors, and the device for cocking the hook and locking it in the cocked position is performed In the form of a single-pole magnet with a control knob mounted on the bottom eyelet and a latch interacting with it with reinforcement mounted on the hook.

New distinctive features of the inventive system for lifting sunken submarines are the presence on the hull of the boat in the area of the lifting butts of docking nodes (sidebars) installed at an equal distance from the longitudinal axial line of the lifting butts, as well as the implementation of the device for raising the hook and locking it in the cocked position as a single pole magnet with a control knob mounted on the bottom eyelet and a latch interacting with it with reinforcement mounted on the hook.

These distinctive features provide accurate guidance of the lifting device to the butt of the submarine and its docking with the butt, thereby ensuring the achievement of the stated goal of the invention.

FIG. 1 shows a general view of a system for lifting sunken submarines.

FIG. 2 shows a device for lifting sunken submarines in a side view.

FIG. 3 shows dressing the butt on the butt of the ship's lifting under its own weight.

FIG. 4 shows the process of shifting, fixing and releasing the hook by disconnecting the magnet after removing the tension in the guide conductors.

FIG. 5 shows the transfer of the hook into the working position by applying a vertical load.

The system for lifting sunken submarines includes lifting buttles 2 mounted on the hull 1 of the submarine and docking nodes (pickaxes) 3, to which the guide conductor 5 is attached by means of a swivel 4, and lifting devices. Each lifting device of the system consists of a hook 6 with a latch 7. The hook 6 with an axis 8 is docked with the lower eye 9, which in turn is connected by axis 10 with the upper eye 11. On the eye 11 there are installed lifting brackets 12 with lifting lines 13. On the lower The lug 9 is fitted with a magnet 14 with a control handle 15 and a gateway 16, through which the guide conductors 5 are passed. A lock 17 is installed on the body of the latch 6, which, when the lifting device is aimed at the lifting butt 2, interacts with the magnet 14.

The system for lifting sunken submarines is as follows.

On the sunken submarine, work is carried out to provide access to the lifting heads 2 and docking nodes (axes) 3, after which guides 5 equipped with swivels 4 are delivered to the latter, guides 5 which are diverted or uninhabited remote-controlled underwater vehicles connected with docking nodes (axles) 3. Simultaneously on the support vessel, the lifting devices are assembled. After assembling the devices, the hook 6 in each of them is rotated 90 degrees until the latch 17 with the magnet 14 and the control knob 15 is attached to the magnet 14, as a result of which the latch 17 firmly holds the hook in the required position. Then the guide conductors 5 are slid into the clutches 16 and secured them to sturdy structures near the site of the descent of the lifting device to the sunken submarine. The ends of the lifting straps are transmitted to the lifting device of the supporting vessel, and in this position the lifting device starts to descend along the guide conductors 5 (Fig. 3). The descent is continued until the hook enters the lifting butt 2 (Fig. 4). Then the diver or the uninhabited remote-controlled underwater vehicle, with its manipulator, rotates the handle 15 to release the retainer 17 from the magnet 14, after which the hook 6 under its weight while lifting the lifting device completely enters the lifting butt and is fixed in it by means of the latch 7. Similarly, the installation works other lifting devices on all lifting heads on the sunken submarine. After its lifting with lifting devices of the supporting vessel, the sunken submarine is lifted to the surface.

Technical and economic advantage of the proposed system for lifting a sunken submarine compared with the known system according to the author's certificate No. 1654125, adopted for the prototype, is to simplify the technology and reduce the time for its implementation.

At present, a three-dimensional parametric modeling of the structure of the lifting device of the system and the technological process of its guidance on the lifting heads of the submarine are being carried out.
