Abstract

The utility model discloses a petroleum platform pipeline protective bushing. The petroleum platform pipeline protective bushing comprises two arc sleeves, wherein the bottom of each arc sleeve is provided with a semicircular support assembly; the two semicircular support assemblies are in butt joint so as to form a fixed base; a plurality of triangular reinforcing ribs are uniformly distributed between the outer wall surfaces of the arc sleeves and the fixed base; the outer edge of each triangular reinforcing rib is additionally provided with a reinforcing steel bar bayonet; the vertical heights of the arc sleeves are 40cm. The petroleum platform pipeline protective bushing disclosed by the utility model has the beneficial effects that because the two arc sleeves form a cylindrical protective bushing body, and the plurality of triangular reinforcing ribs are uniformly distributed between the outer wall surfaces of the arc sleeves and the fixed base, and each reinforcing rib is additionally provided with the reinforcing steel bar bayonet, so that the crossed parts of pipe fittings and petroleum pipelines can be prevented from being collided by the external world by accident to influence the pipeline stability; external horizontal reinforcing steel bars can be matched to protect exposed pipelines on an offshore petroleum platform; the normal transportation of the petroleum pipelines is ensured effectively.

Description

A kind of oil platform pipeline sheath

Technical field

The utility model relates to a kind of petroleum pipeline pipe fitting, relates in particular to a kind of oil platform pipeline sheath.

Background technique

Offshore platform generally refers to above tide and has a kind of truss structure of level table, for example, for carrying out manufacturing operation, offshore oil platform.Its form has a formula, guy wire formula and gravity type etc., and stake formula platform wherein consists of cushion cap and pile foundation, and pile foundation has timber, piling bar and reinforced concrete pile etc.; Guy wire formula platform wherein is that a prefabricated head tower is placed on the seafloor foundation piece, with cable wire, along different direction grappling tension, forms; Gravity platform is wherein occupied stably on the firm stratum of seabed by the platform own wt.At present, a lot of pipelines are arranged on offshore oil platform, pipeline need be under platform penetrates into platform, and the intersection of pipeline and platform is not easy to fix very much, and much pipeline is arranged side by side together, not only impact construction, and pipeline itself also is easy to impaired.Thereby, the reinforcing pipe fitting that need to meet specific environment is fixed pipeline and platform, if can only utilize some simple supporting structures to be fixed, comparatively bother on the one hand, caused a large amount of work, need emphasis to be pointed out that, a lot of pipeline external surfaces directly engage with platform, or adopt assembly simply highly less and that tube wall is thinner, are positioned at the situations such as the external impact of lower or corrosion if run into, the stability of pipeline can be directly affected, normal transportation work can't be guaranteed.Therefore, for above aspect, need to make rational improvement.

The model utility content

The purpose of this utility model be to provide a kind of intensity of strengthening pipeline and platform mating face, simple in structure, be convenient to install, with the oil platform pipeline sheath of reinforcing bar bayonet socket, to solve many deficiencies of prior art.

The purpose of this utility model is carried out specific implementation by the following technical programs:

A kind of oil platform pipeline sheath, comprise two arc shrouds, each arc shrouds bottom is with a semicircle supporting component, be positioned at that each arc shrouds end arranges respectively a vertical stiffening rib and a screw is offered on this vertical stiffening rib top, two semicircle supporting components docking form a fixed base; Be uniformly distributed some triangle stiffening ribs between described arc shrouds outer wall and fixed base, on each triangle stiffening rib outer edge, set up a reinforcing bar bayonet socket, the vertical height of described arc shrouds is 40cm.

The vertical height of described arc shrouds is greater than the bottom surface diameter length of fixed base, fixed base surface uniform some locating slots that distribute.

The beneficial effect of oil platform pipeline sheath described in the utility model is: by by two arc shrouds, forming columniform sheath body, and be uniformly distributed some triangle stiffening ribs between arc shrouds outer wall and base, set up again a reinforcing bar bayonet socket on each stiffening rib, can prevent pipe fitting and petroleum pipeline jointing place to be subject to extraneous accidentally the shock and affect pipeline stability, can insert outside extra horizontal reinforcement in bayonet socket, protect the outdoor pipeline on offshore oil platform, extended the working life of pipeline; Can adjust according to actual needs petroleum pipeline, can reduce the amount of labour, increase work efficiency, effectively guarantee the normal transport of petroleum pipeline.

The accompanying drawing explanation

Below according to drawings and embodiments the utility model is described in further detail.

Fig. 1 is the structural drawing of the described oil platform pipeline of the utility model embodiment sheath.

In figure: 1, fixed base; 2, arc shrouds; 3, vertical stiffening rib; 4, locating slot; 5, screw; 6, triangle stiffening rib; 7, reinforcing bar bayonet socket.

Embodiment

As shown in Figure 1, the described oil platform pipeline of the utility model embodiment sheath, comprise two arc shrouds 2, each arc shrouds 2 bottom is with a semicircle supporting component, be positioned at that each arc shrouds 2 end arranges respectively a vertical stiffening rib 3 and a screw 5 is offered on this vertical stiffening rib 3 tops, vertical stiffening rib 3 outer surfaces that are positioned at two arc shrouds 2 of the same side mutually are adjacent to and two sleeve pipes are spliced into the pipe fitting body, and two semicircle supporting components docking are a fixed base 1; The some locating slots 4 that distribute of fixed base 1 surface uniform wherein, simultaneously, two arc shrouds 2 form columniform sheath body, be uniformly distributed some triangle stiffening ribs 6 between described arc shrouds 2 outer wall and fixed base 1, on each triangle stiffening rib 6 outer edge, set up a reinforcing bar bayonet socket 7; The vertical height of described arc shrouds 2 is that 40cm and this highly are greater than the diameter of section length of fixed base 1, and locating slot 4 wherein is ellipsoidal structure.

Claims

1. an oil platform pipeline sheath, comprise two arc shrouds, it is characterized in that:

Each arc shrouds bottom is with a semicircle supporting component, is positioned at that each arc shrouds end arranges respectively a vertical stiffening rib and a screw is offered on this vertical stiffening rib top, and two semicircle supporting components docking form a fixed base;

Be uniformly distributed some triangle stiffening ribs between described arc shrouds outer wall and fixed base, on each triangle stiffening rib outer edge, set up a reinforcing bar bayonet socket, the vertical height of described arc shrouds is 40cm.

2. a kind of oil platform pipeline sheath as claimed in claim 1, it is characterized in that: the vertical height of described arc shrouds is greater than the bottom surface diameter length of fixed base.
