Description

Connecting method for mooring chain counterweight chain

Technical Field

The invention relates to the field of anchor chains, in particular to a mooring chain accessory for mooring an oil platform.

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 sometimes require higher weights for adjusting system stiffness, and counterweights are used. To increase the weight, a weight-balancing weight or a weight-balancing chain may be used. The invention relates to a method for connecting a counterweight chain of a mooring chain. The method connects the counterweight chain in the mooring chain, thereby not only improving the bearing capacity and the safety factor, but also achieving the purpose of counterweight and having higher practical value.

Disclosure of Invention

The invention aims to solve the technical problems and provides a connecting method of a counterweight chain of a mooring chain.

The purpose of the invention is realized as follows: a connecting method of a mooring chain counterweight chain comprises the mooring chain and a counterweight structure, wherein the mooring chain is provided with the counterweight structure, and the connecting method is characterized in that: the counterweight structure include eye plate, D type shackle and join in marriage heavy chain, the counterweight chain left and right sides all fix on the porous of eye plate is served through D type shackle, the haplopore end of eye plate link to each other with the mooring chain through D type shackle.

As a preferred technical scheme: the eye plate can be a three-hole eye plate or a four-hole eye plate; the eye plate is of a triangular structure, one side of the eye plate is provided with a single hole, and the other side of the eye plate is provided with a plurality of holes.

As a preferred technical scheme: when the eye plate is three-hole, two heavy chains are provided; when the eye plate is four holes, the number of the heavy chains is three.

The invention has simple structure, can ensure stable connection of mooring chain links, is convenient to disassemble and assemble, and can be repeatedly used.

Detailed Description

The invention will be further described, but not limited, by reference to the following figures: a mooring chain counterweight chain connecting method comprises a mooring chain 1 and a counterweight structure 2, wherein the counterweight structure 2 is arranged on the mooring chain 1, and the mooring chain connecting method is characterized in that: the counterweight structure 2 include eye plate 3, D type shackle 4 and counterweight chain 5, counterweight chain 5 about both sides all fix on the porous end of eye plate 3 through D type shackle 4, the haplopore end of eye plate 3 link to each other with mooring chain 1 through D type shackle 4.

The eye plate 3 can be a three-hole eye plate or a four-hole eye plate; the eye plate 3 is of a triangular structure, one side of the eye plate is provided with a single hole, and the other side of the eye plate is provided with a plurality of holes. When the eye plate 3 is three holes, two heavy chains 5 are provided; when the eye plate 3 is four holes, three heavy chains 5 are provided.

During specific implementation, one chain is converted into two chains through the two eye plates, so that the purposes of improving the bearing capacity and the weight are achieved. The chain between the two eye plates is increased according to the weight requirement and then is connected with the eye plates through shackles.

To further increase the weight of the heavy chain, the triple-well plate may be replaced with a four-well plate, increasing the heavy chain from one to three. In order to reduce the cost, one of the three counterweight chains can be used as a bearing chain, the counterweight chains on the two sides are not stressed, and split rings can be adopted.

The invention has simple structure, can ensure stable connection of mooring chain links, is convenient to disassemble and assemble, and can be repeatedly used. The invention provides sufficient freedom degree through two mutually perpendicular shackles, prevents the counterweight chain from winding, and also can prevent the counterweight from generating extra torque on the connecting device to cause the premature failure of the connecting device; the structure is simple, the mooring chain links can be stably connected, the assembly and disassembly are convenient, and the mooring chain can be repeatedly used; the counterweight chain can be suspended at any position of the mooring chain, and the size of the cavity can be adjusted according to the size of a chain ring of the mooring chain; the counterweight component at the lower end can be selected according to requirements, and not only can a counterweight chain be used, but also a counterweight block can be used.

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.
