The ship, mostly steam, with the nose closed
(57) Abstract:Usage: shipbuilding. The inventive vessel, mainly steam, with the nose closed, which consists of a fold-up around the horizontal axis of the plot of the stem adjacent to two sides and positioned below the upper deck cut out parts of the sides of the hull. On cut sections of the sides is cut out portion of the upper deck, connected with them and with the appropriate section of the stem in one whole box of hull. Nasal closure is installed with the possibility of pivoting through the cutout of the above-mentioned portion of the upper deck in the open position, mostly above the upper deck. 4 C.p. f-crystals, 6 ill. The invention concerns a ship, mainly the ferry, with the nose closed, which is formed by folding up around the horizontal axis plot the ship's hull at the bow. Nasal closure is designed for opening the vessel in the area of the stem to the so-called transport-type rolling rolling to ensure arriving at the feeding site to hire the preservation of the hull in the longitudinal direction and without changing n the Finance nasal closure of the General bow section of the vessel above the waterline: separated more or less vertical slit from the rest of the hull bow section turns up (and forward) around the axis, which runs parallel transversely from one side wall to another joint. Through so produced nasal hole may lie, for example, the ramp aiming pads on the pier or similar structure.It is obvious that the fold just above the waterline bow section at the large ferry means you need to move large masses. It also requires the use of powerful and expensive running gears and control systems. Besides added that fold-up nasal area closes visibility to the service team just stepping into the Parking lot, i.e., at about sunset on the ferry, across the entire width of the ship; on the other hand, not least because of the folding forward of the nose closed, it is premature opening.Therefore already been made nasal openings, which consisted of two gate leaves, which, forming closed along their common edge of the stem, above the waterline and below the upper deck was tilting to the side on a certain side length of the side walls of the hull. The separation of the nasal openings on the two Nezavisimaya inherent in the above-described nasal closure of the defect, consisting of lower stability, which makes it imperative to take appropriate action when fixing in the closed condition, as well as in the mechanics of opening. However, the advantage is the fact that to open these nasal gates need to move much less weight than in the case described above nasal closure.The technical result of the invention is to combine the advantages of one system with the advantages of another system while excluding mutual weaknesses.To achieve this, the technical result in the ship, mainly the ferry, with the nose closed, includes flip-up around the horizontal axis section of the stem with the adjacent two sides and positioned below the upper deck cut out parts of the sides of the hull, fore closure additionally includes located above the cut sections of the sides of the cut out portion of the upper deck, connected with them and with the appropriate section of the stem in one whole box of hull, and nasal closure is installed with the possibility of pivoting through the cutout of the above-mentioned portion of the upper deck is wow closure insert is therefore, considering the nose holes only necessary in this respect to portions of the sides (as in the system with fold-in side gate valves), as well as from part of the upper deck, which releases sufficient for pivoting the two parts of the sides of the neck. As these three taking place in very different planes of section are rigidly interconnected, hinged box gets high stability. However, due to the fact that the nasal portion of the upper deck, adjacent to the resected portion of the upper deck, can be connected with portions of the sides and to extend beyond the nose close to the front and sides, surrounding the insert (in several dimensions) frame construction of the boat hull and the upper deck also gets high rigidity provided in both protected and open the insert.In addition, the share of mobile masses slightly reduced compared with the specified first nasal closure, which presumably has the same stiffness. This reduces the surface affected by sea wave, making the perceived nasal closure efforts decrease. In addition, due to everything I the operation of the ship is another important advantage, namely, that in comparison with the known nasal closure significantly smaller part of the upper deck in the bow area takes part in the process of opening and accordingly there is a large surface of the deck, down to the stem, traction devices and similar mechanisms.Preferably the nasal closure in the closed position is sealed relative to the rest of the hull. In this case, you need about half the height of passing more or less parallel to the stem joints of the boards, namely, where the distance from the axis of swing of the insert is the smallest, to change the direction of the seal. The necessary measures are known and do not pose any difficulties. In this case, as in General, in an embodiment in accordance with the invention, the role played by the fact that the side of the hull in the bow area strongly act to the side.Preferably the nasal closure in the area running parallel to the longitudinal axis of the vessel side edges of the cut out portion of the upper deck secured to parallel them with the brackets, which are mounted to rotate on the racks fixed on the upper deck. At that time, the swing insert, portion of the upper deck should extend back approximately above the point of changing the direction of the seal, so that the insert is fixed on a relatively long arms, the swing axis which is compared to the only slightly above the upper deck, why insert only in the lower zone runs per weight moving forward, if she leans up.However, the first essential is significantly smaller in width and height of the insert, which significantly improves in comparison with the considered first nasal closure (continuous across the entire width of the ship and the greater the height of the bow section) visibility from the bridge at sunset on the ferry with open nose closed. Nasal closure of the supplied hydraulic cylinders, stationary racks below and acting through the pistons of the brackets.In Fig. 1 shows a longitudinal section of the bow section of the vessel with bow closure in accordance with the invention; Fig. 2 a top view mainly depicted in Fig. 1 bow section of the vessel, but only to its median longitudinal line; Fig. 3 ragged side view of the ship from the front when you open the forward closure; Fig. 4 a section at the line B-B in Fig. 1; and Fig. 6 is another section in accordance with line C-C in Fig. 1.View broken bow section of the ferry in Fig. 1 is an inner side of the left side. Above the nose 1 extends perpendicularly up straight in the example, the stem 2, namely, in the area of the bulwarks 3 outside upper deck 4. From stem 2 back stretch bead 5 is indicated in General by the position 6 of the hull, and the hull of the vessel expands and Board 5 are given in the forward area to the outside.Below the upper deck 4 on both sides of the stem 2 from both sides 5, converging at the stem 2, the cut out part 7, namely along the line 8, which first passes below the upper deck 4 and parallel to it from the stem 2 ago, then basically parallel to the inclined stem back and bottom and returns above the nose 1 to the stem 2. Both cut from the flanges 5 on the side of the left side and on the starboard side parts 7, similar to the wings of a butterfly, are connected to each other in the nasal closure, indicated in General position 9. To correct nasal closure 9 is, in addition, section 10 of the upper deck 4, which closes or releases the notch 11 upper deck 4 (Fig. 2). Plot 10 is rigidly connected to the parts 7 (inter alia by means of vertical struts the radius of the vessel and release in the open position the nasal hole.In Fig. 1 formed above the insertion of the nasal closure 9 shown in solid lines entered in the hull of the vessel 6 to the closed position and the dotted lines mainly in the cast away from the hull 6, namely, in the tilted upward open position. The purpose of reclining on a plot of 10 upper deck 4 and thereby to the forward closure 9 on the side of the left and right sides pinned one bracket 13, each of which is mounted to rotate around a common axis of the swing arm 15 on the rack 14. Lower rack 14 is rigidly fixed to the hydraulic cylinders 16 act in the position 17 of the brackets 13. Lugs are intended for fixation of the brackets 13 and thereby nasal closure 9 in the open position (dotted lines).Visible from the end positions of rotation of the nasal closure 9 movement when opening or closing the nasal closure shows that the cut-out 11 in the upper deck 4 and thereby related to the insertion of nasal closure 9 plot 10 upper deck in the longitudinal direction of the vessel may be shorter than the stretch back part 7 of nasal closure 9. This leads to a compact design of nasal closure 9 and further reduction of the movement is lube 4 lines 8 nasal closure 9 with movement of the opening and closing does not apply pivoting on the side of the nose around related to nasal closure 9 plot 10 upper deck 4 section of the upper deck 4. The same applies to the adjacent sections of the boards above lines 8, so that coupled with the rest of the hull 6 arcuate section 19 of the hull acts and outputted from the front and side beyond forming the nasal closure 9 is inserted. In accordance with this bow closure 9 also does not apply to the bulwark 3.Mostly along the lines of 8 sections 7 nasal closure 9 (relating to the sides 5 of the vessel) is sealed relative to the rest of the body 6 of the vessel, and sealing joints and seals are located inside the hull mostly follows the line 8 dividing joint between the parts 7 and the respective flanges 5.In Fig. 4 6 presents the performance of the location of the seals. Note that in the upper zone of nasal closure in its opening sections 7 immediately penetrate into the housing 6 of the vessel (which is possible due to the very strong speakers there sides 5 ), while in the lower zone areas 7 first moved out, therefore, from surrounding adjacent areas of the flanges 5, before they are later passed through the upper zone exempt open the nasal closure 9 holes on the side of the nose (line 8) sides 5, and through the e 20 line 8 has the smallest distance from the axis of the swing arm 15 of the bracket 13 and thereby nasal closure 9.Located below the point 20 changes direction seal section A-A and B-B (Fig. 4 and 5) show (continuous) o profile 22 of elastic material, which is attached to the console 23, which in turn are welded to the inner surfaces of sections 7 nasal closure 9, namely, in the neighbourhood of the following after line 8 dividing junction 8A. In the shown closed position sealing profile 22 is pressed against the holder 24, which are respectively welded on the inside to the outside Board 5 in parallel console 23.In accordance with section C-C (Fig. 6) above the point 20 changing the direction of the seal provides double seal. With one hand on the corresponding vertical post 12 wall 12A, which is part of the nasal insert closing again on the console 23 is fixed to the sealing profile 22, which is pressed against the holder 24. On the other hand on the bottom side also related to nasal closure 9 section 10, which type of hatch covers several shifted upward relative to the rest of the upper deck 4, is kept elastic sealing strip 25, which is closed nose pressed close to the wall 26 in the form of the coaming, which PrepareAD completeness should be specified, what in the longitudinal direction of the vessel for the nasal closure 9 is retractable and foldable ramp 30, which in the retracted state forms with the inclined sides 31 (seen in Fig. 2 and 3) collision bulkhead, when you open the forward closure can be made and deployed, and, through the bulb nose 1 can be superimposed on the pier or similar structure. 1.
