Abstract
The utility model discloses a deep sea drilling platform R4-level mooring chain accessory connecting shackle structure which is composed of a C-shaped shackle, a T-shaped connecting block, a taper pin and protruding connecting bodies. The two ends of the C-shaped shackle are respectively provided with one protruding connecting body. The protruding connecting bodies extend into the two ends of the T-shaped connecting block, so that the left end and the right end of the T-shaped connecting block are fixed through the protruding connecting bodies. The taper pin is inserted into a cavity of the T-shaped connecting block from an entrance of the back portion of the C-shaped shackle so that the lower end of the T-shaped connecting block can be fixed. The deep sea drilling platform R4-level mooring chain accessory connecting shackle structure is unique in conception, free of welding, free of changing the chemical constituents of a mooring chain shackle, capable of guaranteeing the performance of a product, firm in connection and capable of greatly prolonging the service life of the connecting shackle.
Description
Technical field
The utility model relates to a kind of marine mooring chain annex, particularly a kind of deep sea drilling platform R4 level mooring cable annex joining shackle structure.
Background technology
Along with the quickening of global industrial shift paces, the fabrication portion of ocean engineering has been transferred to Asian countries substantially at present.But the piths such as the anchoring in maritime works's equipment and control panel are still provided by American-European countries enterprise.This shows, develop the one-tenth Analysis of Nested Design of self the deepwater mooring system system and the importance of ability to provide the auxiliary items.
For a long time, platform is the main tool of marine oil and gas development of resources, along with marine resources development is drive on boldly to the field, abyss gradually, traditional jack up fixed platform is no longer applicable, and oil development merchant both domestic and external adopts the deep-sea oil resource toolkits such as semi-submersible drilling unit and Floating Production oil storage system (FPSO) one after another.No matter which kind of instrument all wants permanent mooring in specific marine site, this has just proposed higher, more demand to the deepwater mooring system system, and the needs of problems of the deepwater mooring system system is also increased sharply.
At present, generally utilization R4 level marine mooring chain on deep sea drilling platform, it has the technical characterictic of high strength, obdurability, withstanding corrosion and antifatigue, high-strength tenacity mooring annex joining shackle is exploitation marine resources, Development of Marine shipping and the important mooring annex of coast defence construction, and the safety of ocean operation is had vital impact.
Joining shackle is to use in the mooring system and a kind of part that is connected, part is comprised of two parts, connect with protruding connecing with taper pin, smash general peculiar to vessel unloading, with welding manner protruding connecing with taper pin is fixed, if superhigh intensity mooring joining shackle also is fixed with the method for welding, then in welding process, welding rod can merge with the shackle parent, will change the chemical composition of mooring shackle parent, reduce properties of product, shorten the service life that connects.
The utility model content
The purpose of this utility model namely produces thus, proposes a kind of the solution because welding rod and shackle are merged and causes properties of product to reduce the deep sea drilling platform R4 level mooring cable annex joining shackle structure of reduction of service life.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of deep sea drilling platform R4 level mooring cable annex joining shackle structure, formed by the shackle of C shape, T shape contiguous block, taper pin and protruding connecing, two of described C shape shackle is provided with protruding connecing, the described protruding two ends that are deep into T shape contiguous block that connect, by the protruding two ends, the left and right sides of fixing T shape contiguous block that connect, described taper pin is inserted into the T shape contiguous block cavity from the entrance, back of C shape shackle, fixes the lower end of T shape contiguous block.
The utility model design is unique, need not weld, and can not change the chemical composition of mooring shackle, guarantees properties of product, connects firmly, has greatly prolonged the service life of joining shackle.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: the shackle of 1-C shape, 2-T shape contiguous block, 3-taper pin, 4-is protruding connects.
The specific embodiment
By reference to the accompanying drawings, provide embodiment of the present utility model as follows:
As shown in Figure 1: a kind of deep sea drilling platform R4 level mooring cable annex joining shackle structure, by C shape shackle 1, T shape contiguous block 2, taper pin 3 with protrudingly connect 4 and form, two of described C shape shackle 1 is provided with and protrudingly connects 4, described protruding 4 two ends that are deep into T shape contiguous block 2 that connect, by protruding 4 two ends, the left and right sides of fixing T shape contiguous block 2 that connect, described taper pin 3 is inserted into T shape contiguous block 2 cavitys from the entrance, back of C shape shackle 1, fixes the lower end of T shape contiguous block 2.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although the utility model book has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
Claims (1)
1. deep sea drilling platform R4 level mooring cable annex joining shackle structure, formed by the shackle of C shape, T shape contiguous block, taper pin and protruding connecing, described taper pin is inserted into the T shape contiguous block cavity from the entrance, back of C shape shackle, fix the lower end of T shape contiguous block, two of described C shape shackle is provided with protruding connecing, it is characterized in that being: the described protruding two ends that are deep into T shape contiguous block that connect, by the protruding two ends, the left and right sides of fixing T shape contiguous block that connect.
