Problems solved by technology

At present, engineering plastic towlines or single-layer steel towlines are widely used in the market for CNC machine tools. The length of the towline is generally about a few meters. Poor, due to the characteristics of high strength, high difficulty, and uncertainty in marine operations, the towlines currently on the market cannot meet the needs of offshore platforms in terms of strength, structure, function, and length. requirements

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 to Figure 8 As shown, the multi-layer and multi-pipeline large-scale steel towline system for offshore platforms of the present invention is specially used for multi-layer and multi-pipeline large-scale steel towline systems for offshore platforms, including an external link unit 1, an internal link unit 2 and a basic Seat unit 3. The outer link unit 1 and the inner link unit 2 are hinged sequentially through the pin shaft 1015 and the hinge shaft 10111 of the outer link unit 1 in sequence. In the arc groove 2011, according to the link constraints of the 400mm radius of gyration 2014, the chain plate pitch 2015 of 500mm and the internal and external link rotation angle 2013 of 30°, the chain plate pitch 2015 forms a half regular dodecagon 2018, a symmetrical hinged arc The limit angle of the groove 2011 is the central angle corresponding to t...

Abstract

The invention discloses a multilayer multi-pipeline large steel drag chain system for an offshore platform. The system comprises a plurality of outer chaining units, a plurality of inner chaining units and a pair of base units; two sides of the inner chaining units are hinged to the outer chaining units, and the outer chaining units at the two ends are each hinged to one base unit. According to the multilayer multi-pipeline large steel drag chain system for the offshore platform, a medium pipeline is sufficiently protected against damage in the drag chain reciprocating dragging process, the medium pipeline has the independent transfer space, motion of the medium pipeline is in order, the attractive effect in vision is achieved, the service life of the medium pipeline is prolonged, on the premise of not reducing the bearing capacity and structural rigidity of the drag chain system, main structural parts reduce self weight and consumables of the drag chain system through the metal sheet design, and strength and rigidity of the structural parts are improved.

Description

technical field [0001] The invention relates to a multi-layer and multi-pipeline large-scale steel drag chain system for an offshore platform, belonging to the field of offshore platform production. Background technique [0002] Drag chains are generally used on cables, oil pipes, air pipes, water pipes, and air pipes of machine tools to play the role of traction and protection. At present, they are widely used on machine tools. They not only protect cables, oil pipes, etc., but also make the overall appearance of the machine tool It looks more beautiful. [0003] With the development of the ocean, breakthroughs are being made in the research and development of offshore platforms. There are a large number of pipelines between relatively moving parts on the platform, mainly including pipelines for transmitting power, data, gas, water and other media. Due to the particularity of the marine working environment, The research and development of multi-layer and multi-pipeline lar...
