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.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provides a drag chain structure for an assembled ocean platform.

The utility model provides an assembled drag chain structure for platform, includes mount and connecting axle, the lateral wall and the drag chain group of mount link to each other, drag chain group include a plurality of link joint, a plurality of link joint divide into two sets of parallel arrangement, the middle part of two link joints that parallel links to each other through the crossbeam, the link joint include first link joint, second link joint, third link joint, first link joint is fixed continuous with the second link joint, the third link joint link to each other through pivot and second link joint, all link to each other through rotatory third link joint between the adjacent link joint, the connecting axle pass the middle part of third link joint, first link joint in proper order.

As a further improvement, the number of the cross beams is two.

As a further improvement, the first chain plate is connected with the second chain plate through welding.

As a further improvement, the surfaces of the plurality of chain plates are provided with polytetrafluoroethylene protective layers.

As a further improvement, the surface of the cross beam 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.

As a further improvement, the size and shape of the first link plate are equal to those of the third link plate.

Has the advantages that:

compared with the traditional drag chain, the drag chain has the advantages of simple structure, attractive design and no influence on practicability, the rotation angle of the drag chain can reach more than 180 degrees in the actual use, the use requirement of the drag chain is greatly met, the special connection design is adopted between the adjacent chain plates, the disassembly, the assembly and the assembly are more convenient, the working time of workers is saved, the working efficiency is greatly improved, the transportation is convenient, and the drag chain can be adjusted at any time according to the length of the needed drag chain.
