Description

The emergent traction of oil carrier afterbody and after drag combination mechanism

(1) technical field

The present invention relates to emergent traction of oil carrier afterbody and back dragging device, particularly relate to the emergent traction of oil carrier afterbody and after drag combination mechanism.

(2) background technology

All above model oil carriers of 2 tons need satisfy the relevant clause (will execute pot life later) of " OCIMF " (international petroleum association) suggestion, in the afterbody ship, locate except that the emergent towing device of afterbody, should add the back dragging device, thereafter it is 100 tonnes that mooring pipe that drags and powerful point require the load allowable of 20000 tons to 50000 tons boats and ships, and the load allowable of the boats and ships more than 50000 tons is 200 tonnes.Be designed to separation type in the past, and promptly in the afterbody upper deck an emergent towing device of one cover afterbody and a cover back dragging device be set respectively, its drawback is that the occupation of land space is big, and the brute force point that then drags is arranged on the steering engine room top, need add very big additional strengthening.For some oil carrier, adopt separation type may cause afterbody mooring arrangement plan to be difficult to design if the space of afterbody main deck is narrow and small, the not enough problem in afterbody berthing accommodation operational space appears.

(3) summary of the invention

The technical problem to be solved in the present invention, providing the mooring pipe of a kind of general back dragging device and the brute force point of the emergent traction of afterbody combines, have that to take up an area of the space little, can guarantee to finish synchronously two devices operations, be cost is low, practicality the is good emergent traction of oil carrier afterbody and after drag combination mechanism.

The technical scheme that adopts is:

The emergent traction of oil carrier afterbody and after drag combination mechanism, comprise mooring pipe member, the powerful point of emergent traction member, steel axle.It is characterized in that:

The mooring pipe wall of described mooring pipe member is provided with the multiple tracks reinforced rib;

The powerful point of described emergent traction member is by top blind flange, two deep brackets in the outside, inboard two deep brackets, the top lap plate, base plate and emergent traction are formed, emergent traction is fixedly connected on the base plate, top blind flange is captiveed joint with emergent traction by gusset, two deep brackets in the outside are benchmark with mooring pipe member level to two reinforced rib width, be fixedly connected on two deep bracket bottoms, the outside on the base plate respectively, the inboard of two deep brackets in the outside is by the position of setting, be fixedly connected on two deep bracket bottoms, inboard on the base plate respectively, the top lap plate is fixedly connected on two deep brackets in the outside and the top of inboard two deep brackets, constitutes the powerful point of emergent traction member;

Described steel axle one end is equipped with baffle plate, other end dress locating dowel pin;

Described mooring pipe member is installed in the powerful point of emergent traction member top, and be fixedly connected on top blind flange respectively, on two deep brackets in the outside and inboard two deep brackets, selected position is processed with axis hole on two deep brackets in the outside and inboard two deep brackets, the steel axle penetrates axis hole, the powerful point of the traction of will meeting an urgent need member location and captive joint are above deck, emergent traction termination outlet on the powerful point of the wherein emergent traction member is used for the emergent traction of afterbody, and the deck formula mooring pipe member at the powerful point of emergent traction member top and emergent traction powerful put member outside, the steel axle of installing on the inboard deep bracket drags use after being.

Two deep brackets in above-mentioned inboard are separately fixed on the base plate for 1.5 times of positions of width, emergent traction termination down to looking younger.

Selected position processes axis hole on two deep brackets in the above-mentioned outside and inboard two deep brackets, and the axis hole position should guarantee the clear space of 1.5 times of emergent at least relatively traction termination width.

The present invention is applied on 159000 tons of crude oil carriers, its feasibility and practicality have fully been verified, well solve afterbody and added the little problem in dragging device space, back, not only removed the ship building cost low, also obtained shipowner's satisfaction, advantage is to have to take up an area of little, the quick operation in space, safe, can guarantee to finish synchronously the emergent traction of afterbody and after drag operation.

(5) specific embodiment

The emergent traction of oil carrier afterbody and after drag combination mechanism, comprise mooring pipe member 1, the powerful point of emergent traction member 2, steel axle 3.Implementation step is as follows:

1, load allowable of making is 200 tonnes a deck formula mooring pipe member 1, has established five road reinforced ribs 4 on the mooring pipe wall, and wherein horizontal direction is provided with twice and symmetrical;

2, make the powerful point of the emergent traction of flat placed type member 2, the powerful point of emergent traction member 2 is made up of top blind flange 5, two deep brackets 6 in the outside, inboard two deep brackets 7, top lap plate 8, base plate 9 and emergent traction 10.Emergent traction 10 is fixedly connected on the base plate 9, the size of top blind flange 5 sizes and mooring pipe member 1 is complementary, top blind flange 5 is captiveed joint with emergent traction 10 by gusset 11, two deep brackets 6 in the outside are benchmark with mooring pipe member 1 level to two reinforced ribs, 4 width, two deep bracket 6 bottoms, the outside are fixedly connected on respectively on the base plate 9, the inboard of while two deep brackets 6 in the outside is with the position of 1.5 times of emergent traction 10 termination width, two deep bracket 7 bottoms, inboard are fixedly connected on respectively on the base plate 9, on two deep brackets 6 in the top lap plate 8 captive joints outside and the top of inboard two deep brackets 7 constitutes the powerful point of emergent traction member.
