Abstract
A connecting device of a mooring chain and a floating body comprises the mooring chain, an eye plate and the floating body, wherein the floating body is provided with the eye plate, the mooring chain is connected with the eye plate, the eye plate is provided with a shackle structure, and the shackle structure comprises a shackle A, a shackle B and a connecting shackle; the shackle A is connected with the eye plate, the shackle B is connected with the shackle A, the connecting shackle is connected with the shackle B, and the connecting shackle is connected with the mooring chain; the shackle A and the shackle B are vertically arranged. The invention provides a rotation angle for the mooring chain in two mutually perpendicular directions through two shackles with the same structure and size, thereby avoiding the damage of chain rings and accessories due to distortion or the reduction of fatigue life.
Description
Technical Field
The utility model relates to an anchor chain field, in particular to be used for a mooring chain annex that is used for oil platform to moor.
Background
Mooring chains are important equipment for mooring and positioning of offshore floats, wherein steel chains are indispensable components in mooring systems due to excellent bearing capacity, fatigue resistance and wear resistance. Mooring chains on drilling platforms are typically connected to the platform by anchors and chain stoppers, while production platforms and other buoys that do not require adjustment of the chain length are typically connected directly to the mooring chains. An eye plate is left in the water surface department of the floating body, and the chain is connected with the eye plate through a shackle. If directly connect chain and eye-plate, the chain can be because the torsion produces the moment of torsion sometimes, produces the shearing force to eye-plate or shackle horizontal pin, is unfavorable to safety.
Disclosure of Invention
The present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a connecting device for a mooring chain and a buoyant body.
The purpose of the invention is realized as follows: the utility model provides a connecting device of mooring chain and body, includes mooring chain, eye-plate and body, the body on be provided with the eye-plate, mooring chain and eye-plate link to each other its characterized in that: the eye plate is provided with a shackle structure, and the shackle structure comprises a shackle A, a shackle B and a connecting shackle; the shackle A is connected with the eye plate, the shackle B is connected with the shackle A, the connecting shackle is connected with the shackle B, and the connecting shackle is connected with the mooring chain; the shackle A and the shackle B are vertically arranged.
As a preferred technical scheme: the size structure and the size of the shackle A are the same as those of the shackle B.
As a preferred technical scheme: and a transverse pin of the shackle A penetrates through the eye plate to be fixed.
The invention provides a rotation angle for the mooring chain in two mutually perpendicular directions through two shackles with the same structure and size, thereby avoiding the damage of chain rings and accessories due to distortion or the reduction of fatigue life.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
in the figure: 1. a mooring chain; 2. an eye plate; 3. a float; 4. a shackle structure; 5. shackle A; 6. b, shackle B; 7. and connecting and disassembling the shackle.
Detailed Description
The invention will be further described, but not limited, by reference to the following figures: the utility model provides a connecting device of mooring chain and body, includes mooring chain 1, eye plate 2 and body 3, body 3 on be provided with eye plate 2, mooring chain 1 link to each other its characterized in that with eye plate 2: the eye plate 2 is provided with a shackle structure 4, and the shackle structure 4 comprises a shackle A5, a shackle B6 and a connecting shackle 7; the shackle A5 is connected with the eye plate 2, the shackle B6 is connected with the shackle A5, the connecting shackle 7 is connected with the shackle B6, and the connecting shackle 7 is connected with the mooring chain 1; the shackle A5 is perpendicular to the shackle B6.
The shackle A5 is the same as shackle B6 in size structure and size. The cross pin of shackle a5 is fixed through eye plate 2.
During specific implementation, the degree of freedom of the upper end of the mooring chain is increased by adding the transitional accessories, so that the mooring chain can rotate in a certain angle, the shearing force caused by chain distortion is reduced, and the mooring chain has higher practical value.
Two shackles of identical construction and size provide rotation angles for the mooring chain in two mutually perpendicular directions, thereby avoiding breakage of the chain links and accessories due to twisting or resulting in reduced fatigue life.
If two parallel eye plates are arranged at the same position on the floating body, the transverse pin can be simultaneously inserted into the two eye plates by increasing the inner width of the shackle A, and the functions can be realized.
The above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, but not intended to limit the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
