Description

The invention relates to shipbuilding, in particular to vessels for the transport of lighters and cargo. A ship for the transport of lighters and cargoes is known, comprising a hull with double sides, a cargo deck with a hatch, and a semi-tarmac aft end, in the hulls of which are located engine rooms, as well as a deck lifting and transporting device 1. However, a well-known vessel cannot be operated in ice conditions; moreover, it has insufficient lighter compatibility. The purpose of the invention is to enhance the functionality of the vessel by increasing the tonnage and ensuring ice flow. This goal is achieved by the fact that a ship for the transportation of lighters and cargoes, containing a hull with double sides, a cargo deck with a hatch, and a semi-tamama casing, are equipped with engine compartments in the hulls as well as a deck lifting and transporting device. With each other, bow and stern transport devices located in the hold, the last of which is designed to be rotated in a horizontal plane in the interface between the said devices and the manhole, as well as between the engine compartments of the ice fairing having a nose: feed and bottom parts, and a fixed nose part with the ability to rotate relative to the horizontal axis on the bottom of the ship's hull, while the feed part of the boat has the wedge-shaped form, and its bottom part is made with contours corresponding to the shape of the hull contours of the end of the ship hull. In addition, the hull is made with a double bottom, the height of which in the fore and aft compartments of the hold is correlated within 2: 1. FIG. 1 shows a vessel, a longitudinal section; in fig. 2 hold, view from above; in fig. 3 - trial, cross section, in the area of the mid-frame; in fig. 4 - then in the area of the cargo hatch; FIG. 5 is the same in the area of the cargo chamber; FIG. 6 - the same, in the area of the stern in FIG. 7 — feed and bow buffering devices, top view; in fig. 8 - aft towing its device, the cross section; in fig. 9 is the same longitudinal section, in FIG. 10, the ice shell, side view; figure 11 is the same, view in plan. The hull of the vessel has an icebreaking bow 1, upper deck 2, inclined or ledge double bottom 3, whose height in the bow and aft compartments correlates to 2: 1, hold 4, bow superstructure 5, engine compartments 6, double sides 7, transitional cargo a chamber 8, closed in the stern by the battoport 9, a semi-tunnel aft 10, in which the propellers 11 are located, the stern gates 12 closed by the ice fairing 13, and the cargo hatch 14. Lighters 15 are located in the hold and on the upper deck. On deck, the lighters are moved by a mobile gantry crane 16, and the lifting and lowering is done by the spreader 17, which grips the lifting heads 18 of the lighter. In the transfer chamber, the lighter for lifting heads is captured by the frame 19 connected by telescopic columns 20 to the stern transport device 21, which is moved on the carriage 22 along rails 23 before being connected to the rails 24 located in the stern of the hold. In the hold, the lighters move along the rails 25 with a new transport device 26 consisting of the transverse beam 27, carriages 28 and telescopic columns 29. The pivoting locking device 30 consists of a pin 31, which can be rotated around the axis 32, and fingers 33, and non-working The position is stored in a niche 34 located in a double board. The bottom part of the 35th ice shell is made in the shape of the hull aft lines. The ice fairing has the ability to rotate around a horizontal axis 36 fixed in the area of the aft bulkhead 37 of the engine room, and is lowered and lifted using winches 38 located on the deck of the utah 39. The cargo hatch has a hatch cover 40. The vessel is loaded as follows. The vessel is installed on the core in the places of the production of cargo operations., And outboard water enters the hold of the S11motek. When a dichter-carrying sediment is reached, at which the lighters can be loaded into the hold, the ice fairing 13 is lowered by means of winches 38 located on those 39, turning around axis 36. The stern gate 12 is opened by lifting the waterproof i-bayoport 9 and the lighter 15 is entered

a pusher tug into the transitional cargo chamber 8 located between the engine compartments 6. From the niches 34, the pivoting locking devices 30 are extended, the pins 31 with the finger 33 capture the corners of the lighter 15 and fix its position in the transitional cargo chamber 8, the Stern transporting device 21 automatically mounted above the lighter, telescopic columns 21 are extended from the carriage 22, which lower the frame 19 onto the lifting heads 18 of the lighter. Produced coupling. The rotary locking devices are removed, rotated by 90, and the carriage 22 begins to move along the rails 23 in the transitional load box 8, and with it the lighter moves. At the aft of the hold 4, the carriage 22 reaches the rail 24, the carriage wheels turn 45 ° and the carriage starts to move along the rails 24, and the lighter turns 90 ° in the hold. From the longitudinal position, the lighter passes to the lateral position towards the vessel. The position of the lighter in the hold is fixed by rotating locking devices from two sides in the same sequence as in the transitional load box. The telescopic columns 20-raises the frame

; 1-9, the trolley 22 ino turns on the rails 24 in the opposite direction, the trolley wheels are rotated 45 also in the opposite direction and the trolley 22 starts to move along the rails 23 towards the transition chamber to tow the next lighter inserted into the transition chamber .RU. At the same time, the nasal conveying device 26 is fed along the rails 25, the beam 27 of which is mounted in the plane of the lifting heads 18 of the lighter located closer to the cargo hatch 14. The telescopic columns 29 are lowered and the lifting heads 18 of the lighter 15 are gripped. the locking devices 30 and the lighter 15 are fed into the nose of the bilge 4 with the help of the nasal conveying device 26,

After loading the bow of the hold 4, loading of the lighters 15 onto deck 2 begins. For this, the lighter 15 is installed in the cargo compartment light 14, which opens in advance and the door closure 40 is installed and the cargo crane 16 is above the access door. Lighter 15 is rigidly fixed by a pivoting locking device 30. With the help of a cargo crane 16, a spreader 17 is lowered to pick up the lifting heads 1B of the lighter 15, then the lighter 15 is lifted through the hatch 14 above the upper deck 2. The crane 16 moves the lighter 15 to the appropriate position of the boom.

After loading the bow of the cargo hold 4, the deck 2 and the aft part of the cargo hold 4, the cargo hatch 14 is closed, the lighters 15 are mounted on the upper deck 2, the waterproof bast port 9 is closed and the ice fairing 13 is raised in the stern, Proceedings pump out the water ballast from hold 4 and fix the lighters are 15. The vessel is ready to go on a voyage

5 to areas of freezing seas and rivers;

When the vessel is unloaded, the sequence of operations for unloading lighters is carried out in the opposite direction. ke. Lighters 15 are first unloaded

0 installed in the aft part of the hold 4 (to the hatch 14J, then the deck lighters 15 are unloaded and the last lighters 15 are unloaded, located in the forward part of the hold 4,

The ballasting sequence of the vessel, the lowering of the ice fairing 13 and the opening of the waterproof bataport 9, the towing and turning of the lighters 15 are the same as when loading the vessel, in the same or in reverse order. The technology of cargo operations is structured in such a way that all operations are carried out consistently and the whole loading / unloading process can be fully automated. The presence of columns 20 and 29 of the telescopic type on the nasal conveying 26 and the aft conveying 21- devices ensures the capture of lifting heads, 18 with any lighter draft 15.

 The proposed implementation of the vessel allows to increase its cargo capacity and ensure high ice flow.
