Description

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

A known system for lifting sunken submarines, consisting of a set of counterparts mounted on a submarine, including a round cross-section butt, mounted on a sturdy hull of the submarine, and a rod connected to the butt by means of links, means for attaching a rod grip type ШУ, interacting with stock, and lifting pontoons. The head of the rod is equipped with a slot with a roller for securing a guide conductor in it, with the help of which the gripper and the rod are guided and docked. In the stowed position, the rod and links are attached to the hinged (tear-off) sheet of the light hull of the submarine, while the fastening of the links should ensure their separation by a force of up to 3 tf. In addition, to prevent mutual movements during the movement of the boat, the links are fastened to each other using tacks. The rod device, in turn, has a housing, inside of which there is a device for semi-automatic gripping and securing the rod head and rod stop, and on the outside there is a mechanism for disconnecting the rod from the device. At the top of the hull there are eyes for lifting brackets, with the help of which lifting hoisting pontoons are connected to the device, see, Specialist's Manual, Naval Forces of Naval Forces, M., Military Publishing House, 1967, pp. 135-138.

The disadvantages of this system are the rather large mass and dimensions of the rod and links at low load capacities and the volume they occupy on the boat. The number of sets of mates and the values of their parameters increases with increasing lifting weight of the submarine. This leads to a decrease in the useful volume for placing on the boat the means providing tasks for which a submarine was created. The rod device has a complex structure, requires the introduction of an additional device for pointing the device to the rod. The presence of a large number of moving parts reduces the reliability of the device. In addition, a large number of sets of reciprocal parts and means of attachment leads to an increase in the number of ship-lifting pontoons, which can be dropped on a sunken submarine only if the pontoons are located at different heights above the boat. This leads to an increase in the number of stages of the ascent process and, as a consequence, to an increase in the duration of the ascent and its cost.

A known system for lifting sunken submarines, consisting of a counterpart in the form of a round cross-section butt, mounted on a sturdy hull of the boat, fastening means in the form of a load-gripping device for butts (such as “Bracket”), interacting with the butt, and lifting pontoons, means body the fastenings are made in the form of a ship-lifting bracket body, a finger having a stop at one end, and a screw placed on the other end, placed inside the casing and interacting with the nut, a slider installed between the hull cheeks and interacting in operating time with a finger, and a boot mounted on the outside of the case. The emphasis of the finger and the butt are equipped with nodes for winding the guide rope in them when lowering the means for attaching the lifting jacks to the butt. To fasten the end of the guide rope to the submarine, a pin with a cartridge is installed on a sturdy hull near the butt, see, for example, a load gripping device for butts (such as “Bracket”), described in the “Ship lifting operations manual” RSPR-VMF-88, M. , Military Publishing House, 1991, pp. 220-225. This device is taken as a prototype.

The exception from the set of reciprocal parts of the system for lifting sunken submarines of the rod and links reduced its mass. Reducing the number of moving parts and simplifying the design of the means of fastening the lifting pontoons to the butt increases the reliability of the system. However, this system has all the other disadvantages inherent in the system described above. In addition, the design of the fastening means not only did not reduce the space required for installation on the sturdy hull of the submarine around the butt, but, on the contrary, increased it, which leads to a decrease in the useful volume for placing means on the boat for the tasks for which the submarine was created. The use of fasteners also requires the introduction of an additional device for pointing it to the butt.

The objective of the invention is to simplify the design of the system for lifting sunken submarines, the technology of its use and reducing the cost of lifting.

The problem is solved in that in the known system for lifting sunken submarines, containing butts mounted on a sturdy hull of a submarine, fixing means interacting with it, comprising a hull, a pin with a locking mechanism and butts in the upper part of the hull, and ship lifting pontoons, a yoke is included, equipped with attachment points for slings of the butts of attachment means, stops with drives, attachment points for lifting slings, on which ship-lifting pontoons are sharpened one above the other, mounted on a solid body ce submarine embodied as eyebolts mounted on a frame plate with reinforcements on both sides of the plate at its midpoint and a central hole, and the inner space of the housing fastening means identical to the outer contour mounted on the pressure hull of the submarine lugs.

New significant features of the proposed device are:

- the presence in the system of the traverse, equipped with attachment points of the slings of the butts of the butts of the attachment means, stops with drives, attachment points of the lifting slings;

- the execution of the butts mounted on the sturdy hull of the submarine in the form of a plate mounted on the frame with reinforcements on both sides of the plate in its middle and central hole;

- the implementation of the internal space of the hull of the fastening means identical to the outer contour of the butt mounted on the sturdy hull of the submarine;

- the point of the ship-lifting pontoon one above the other on lifting slings.

The presence of the traverse allows you to fix at the optimum height above the sunken submarine for each butt a larger number of existing ship-lifting pontoons, which reduces the number of lifting steps.

The proposed design of the butts provides an increase in their carrying capacity and a decrease in the number of sunken submarines on the sturdy hull.

The implementation of the internal space of the hull of the fastening means identical to the outer contour of the butts installed on the sturdy hull of the submarine makes it possible to simplify the process of pointing and securing it to the butt and to exclude from the system additional equipment for pointing it to the butt.

In general, the simplification of the design of the system for lifting sunken submarines, the technology of its use and the reduction in the cost of lifting operations is provided.

The system for lifting sunken submarines consists of butts, each of which is made in the form of plates 2. On the middle of each side, the plate is equipped with reinforcements 3. A central hole passes through the body of the plate and reinforcements 4. It interacts with the butt fastening means comprising a hull 5, the inner space of which is identical to the outer contour of the butts mounted on the sturdy hull of the submarine, and a finger 6. The hull is also made through a hole 7, the diameter of which is equal to the diameter of the central hole of the butt, and in the upper part of the body are installed butt 8, in which during use the fastening means are fixed with one of its ends of the slings 9.

The other ends of the slings 9 are mounted on the traverse 10, on which the nodes 11 are mounted for attaching the ends of the slings 9, the fastening nodes 12 on the traverse of the slings 13 for lowering the traverse to the sunken submarine, the nodes 14 for sharpening on the traverse of the lifting pontoons 15, as well as the stops 16 s heels 17 and drives for moving the stops in the guides 18 and locking them in a predetermined position.

The use of the system when lifting a sunken submarine is as follows:

On a sunken submarine, divers remove part of the outer hull of the boat in the vicinity of the butts on the sturdy hull 1. At the same time, work is being done on the deck of the supply vessel to prepare the fastening means and crosshead 10 for launching to the sunken submarine. The preparation of the fastening means consists in attaching to the ends 8 the end seals of the slings 9 and the launch slings 19 to the other end seals of the slings 9. The preparation of the traverse 10 consists in securing the ends of the composite lifting slings 20 in the nodes 14 of the traverse, connecting to the other ends of the slings 20 of the slings 19, laying lifting slings 20 on the deck beam and securing the ends of the slings 19 on the supply vessel. After that, each fastener is lowered to the corresponding butt on the sturdy hull of the submarine and, under the control of the diver, it lands on the butt. Then the diver makes the finger 6 in the hole 4 of the butt and hole 7 in the housing of the fastener and fixes it in the holes in one of the known ways.

After joining the fastening means and the butt, the upper ends of the launch slings pass through the nodes 11 of the beam 10 and on the lines 13 connected to the nodes 12 of the beam, lower it to the sunken submarine until the end terminations of the slings 9 pass through the nodes 11. Then with using the wires, lower the stops 16 until they touch the toes 17 of the hull 2 of the submarine and tighten the slings 9 tightly, after which the stops stop in this position. The traverse is ready to point ship-lifting pontoons 15 on it, while the lifting slings 20 occupy a vertical position.

Slings 19 are brought into the closures of one of the ship’s lifting pontoons 15 with attached purging hoses and the pontoon 15 is lowered to the traverse 10 by the work of the lifting mechanisms until the connecting elements of the composite lifting sling 19 pass through the pontoon cover 15. The pontoon is lowered. Then the pontoon is blown up and put it “on the pan”. Then the next pontoon 15 is lowered along these slings and put it “on the pan” on the first pontoon. The sharpening of all other pontoons on the crosshead 10 is carried out similarly.

After sharpening the required number of ship-lifting pontoons on a sunken submarine, they are purged and, by increasing their lifting force, the sunken submarine is raised to the surface upon the appearance of the upper tier of the ship-lifting pontoons. In this position, the sunken submarine, along with the ship-lifting pontoons, is towed in shallow water, and after the pontoons are rebuilt, the sunken submarine is finally lifted.

The technical and economic advantage of the proposed system for lifting sunken submarines compared with the known system described in the "Guide to the lifting operations" RSPR-Navy-88, M., Military Publishing House, 1991, pp. 220-225 and adopted as a prototype, is simplification of the design of the system for lifting sunken submarines, the technology of its use and reducing the cost of lifting operations.

An investment of about 35 million rubles is required to develop and manufacture the fastening means and traverse of the proposed system for raising sunken submarines. Currently, a preliminary design of the fastener and traverse constructions of the proposed system has been completed.
