(54) КОРМОВАЯ ОКОНЕЧНОСТЬ ТРАУЛЕРА(54) AFT TRAULER FEED

1one

Изобретение относитс к судостроению, а именно к конструированию кормовой оконечности траулера.The invention relates to shipbuilding, in particular to the design of the aft end of a trawler.

Известна кормова оконечность траулера , содержаща устройство дл спуска и подъема трала, включающее ваерные лебедки , установленные по сторонам слипа на промысловой палубе, на которой установлены кронштейны, с подвешенными на них ваерными блоками дл проводки ваеров, а в средней части оконечности установлены рыбный бункер дл приема рыбы и барабан намотки сетной части трала 1.The known trawler stern end contains a device for lowering and lifting a trawl, including warp winches mounted on the sides of the slip on the fishing deck, on which brackets are mounted, with warp blocks suspended from them for wire warping, and in the middle part of the extremity there is a fish bunker for receiving fish and drum winding net part of the trawl 1.

Недостаток указанной оконечности - низка остойчивость траулера и сложность в обслуживании.The disadvantage of this tip is low stability of the trawler and maintenance difficulty.

Цель изобретени - повышение остойчивости траулера и улучшение условий обслуживани .The purpose of the invention is to increase the stability of the trawler and improve service conditions.

Поставленна цель достигаетс тем, что оконечность снабжена аппарелью с дугообразной оконечностью, роллом и отбойными листами, барабан дл намотки сетной части трала установлен на промысловой палубе между слипом и рыбным бункером, а аппарель выполнена с щириной, равной п ири11е слипа, и установлена с возможностью поворота в районе пересечени слипа с промысловой палубой, рол установлен на дугообразной оконечности аппарели, а отбойные листы - по продольным кра м аппарели, и каждый из них выполнен с торцовой поверхностью по форме слипа.The goal is achieved by the fact that the tip is equipped with a ramp with arcuate extremity, roll and fender sheets, a drum for winding the net part of the trawl is installed on the fishing deck between the slip and the fish bunker, and the ramp is made with a width equal to the length of the slip and installed with the possibility of rotation. in the area of intersection of the slip with the fishing deck, the roll is installed on the arcuate tip of the ramp, and the fender sheets along the longitudinal edges of the ramp, and each of them is made with an end surface in the shape of a slip.

Предлагаема кормова оконечность содержит ваерные лебедки 1, установленные по сторонам слипа 2, кронштейны 3 с подвесными ваерными блоками 4 дл проводки ваеров 5, бункер 6 дл приема рыбы, бара15 бан 7 дл намотки сетной части трала, установленный на промысловой палубе 8 между слипом 2 и рыбным бункером 6, а также аппарель 9, щарнирно закрепленную в районе пересечени слипа 2 с палубой 8, щириной равной слипу и имеющей дугообразную частьThe proposed stern end contains warping winches 1 mounted on the sides of slip 2, brackets 3 with suspended warp blocks 4 for posting warders 5, hopper 6 for receiving fish, bar 15 ban 7 for winding the net part of the trawl mounted on the fishing deck 8 between slip 2 and fish bunker 6, as well as a ramp 9, hinged at the intersection of the slip 2 with the deck 8, the width equal to the slip and having an arcuate portion

Claims

20 10 (in the lowered position, the ramp is part of the deck, and its arcuate extremity is part of the bulwark; in the raised position, the ramp 9 is an extension of the slip, and its arcuate part 10, covering the drum 7, provides the possibility of lifting the hook 11 with the catch vessel). Roller 12 is installed on the arcuate portion 10 of the ramp, preventing wear of the net part 13 of the trawl during its descent.5 Along the longitudinal edges of the ramp 9, baffle plates 14 are installed, repeating the shape of the slip 2 and serving in the lowered position of the ramp as stops, and in the raised position - as chippers holding Kutok 11 with the catch on the ramp 9. The stern tip is made with the bulwark 15. The stern tip of the trawler works as follows. Before lowering the trawl, the ramp 9 is lowered to the position in which it is part of deck 8 and the bulwark 15. The bumper plates 14, abutted against the slip 2, are the support of the ramp. By winding the drum 7 through the roll 12, the net part 13 of the trawl is lowered. 20 After the net part 13 of the trawl is lowered, it is connected to the warp 5 and etched the warp by means of warp winches 1 to the required depth. The trawl is lifted in the reverse order before approaching the feed of the kutka 11 with fish, after which the ramp 9 rises to the position in which it is a continuation of the slip 2 covering the drum 7 and the flank 11 with the fish on the elip 2 and the ramp 9 using Well-known cargo-lifting devices, for example, a portal with cargo brooks (not shown), rises to deck 8 and is fed to bunker 6, while the fender plates 14 hold pin 11 on the ramp. The advantage of the proposed aft tip is to simplify maintenance and reduce the center of gravity. This improves the ship’s stability and, as a result, its payload, which is especially important for small ships (for example, for low-tonnage coastal trawlers, the payload increases by 20-30%). The invention of the stern end of the trawler, comprising a device for lowering and lifting the trawl, including warp winches mounted on the sides of the slip on the fishing deck, on which brackets are mounted with welded warp blocks mounted on them, and in the middle part of the tip there is a fish buiper for receiving The fish and the winding drum of the net part of the trawl, characterized in that, in order to increase the stability of the trawler, to improve the conditions of service, it is equipped with a ramp with an arched tip; ohm and fender sheets, while the drum for winding the net part of the trawl is installed on the fishing deck between the interpolation slip and fish tank, and the ramp is made with a width equal to the width of the slip, and is installed with the possibility of rotation in the area of intersection of the slip with the fishing deck, while the roll is set on the arcuate tip of the ramp, and the bumper sheets - along the longitudinal edges of the ramp, and each of them is made with an end surface in the form of a slip, Sources of information taken into account during the examination 1.
