With the development of oceans, the development of ocean platforms is making continuous breakthrough, and a large number of pipelines exist among relatively moving parts on the platforms, mainly including pipelines for transmitting various media such as electric power, data, gas and water, and due to the particularity of ocean working environments, the development of multilayer multi-pipeline large steel drag chains for protecting the pipelines and enabling the pipelines to move along a set track is called as a key point of the development of maritime work equipment.

Due to the special line of ocean working conditions and the complexity and randomness of the ocean platform in the requirements of various pipelines, the development of a multilayer multi-pipeline large-scale steel drag chain system special for the ocean platform has a plurality of difficulties. The drag chain in the current market is an engineering plastic drag chain or a single-layer steel drag chain used on a numerical control machine tool, the length of the drag chain is generally about several meters, the design is not ingenious, the flexibility is not high, the connection stability is poor, the drag chain cannot be rapidly assembled when the length of the drag chain is not enough, and the drag chain in the current market cannot meet the requirements of a maritime work platform on a drag chain system in terms of strength, structural form, function and length due to the characteristics of high strength, high difficulty, uncertainty and the like of ocean operation.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a special high-strength drag chain system for an ocean platform.

A special high-strength drag chain system for an ocean platform comprises a fixed frame; the side wall of the fixed frame is connected with a drag chain group, the drag chain group comprises a plurality of main body frames,

the plurality of main body frames are divided into two groups which are arranged in parallel, and two adjacent main body frames are connected through a fixed seat; the fixing seats are circular, the two fixing seats are connected through connecting columns, the surfaces of the fixing seats are provided with two semicircular turntables, through holes are formed in the turntables, riveting columns are arranged on the main body frame, and the riveting columns penetrate through the through holes in the turntables.

the plurality of main body frames 2 are divided into two groups which are arranged in parallel, and two adjacent main body frames 2 are connected through a fixed seat 4; the two parallel main body frames 2 are connected by two cross beams 3. The surface of the beam 3 is provided with a replaceable gasket, and the surface of the gasket is provided with a groove structure matched with a pipeline to be conveyed.

The fixing seats 4 are circular, the two fixing seats 4 are connected through connecting columns, the surfaces of the fixing seats 4 are provided with two semicircular turntables, through holes are formed in the turntables, the main body frame 2 is provided with riveting columns 6, and the riveting columns 6 penetrate through the through holes in the turntables.

Two adjacent connecting columns 5 are connected through an intermediate shaft 7, the intermediate shaft 7 is of a hollow structure, and the inner part of the intermediate shaft 7 is used for laying lines.

The working condition is as follows:

the main body frame 2 of head and tail is installed respectively on the carousel of difference, and the rotatable angle of carousel is decided according to the interval of adjacent rivet, produces great angular migration because of the stormy waves in order to prevent the tow chain. When the rivet is used, the distance between adjacent rivets can be reduced as much as possible, so that the safety of an internal pipeline is ensured.

Simultaneously, install force transducer and angle alarm additional in the jackshaft, when the power that individual tow chain bore or the angle of skew is too big, warning that can be timely to make things convenient for maintainer to maintain.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
