Abstract
The utility model discloses a kind of submarine pipeline bending arrestor of Fast Installation, including 2 chip size identical half-watts, the both sides of every half-watt extend outward one block of web respectively, and 2 half-watt webs are fastenedly connected by bolt through the fixing hole on 2 half-watt webs.The beneficial effects of the utility model are, simple and reliable for structure, and assembling is convenient, comprehensive cost of manufacture is lower, it is possible to achieve the Fast Installation in construction, and once success rate is close to 100%, higher than the buckle arrestor of other forms, taken so as to effectively reduce ship, reduce integral construction expense.
Description
Technical field
It the utility model is related to submarine pipeline technical field of auxiliary equipment, more particularly to a kind of submarine pipeline of Fast Installation
Buckle arrestor.
Background technology
Submarine pipeline easily produces local buckling in the presence of bending stress and external hydrostatic water pressure power.In actual items
In, original buckle arrestor often uses welded type or monoblock type, that is, is designed to two panels half-watt make-up and be welded on extra large pipe mother metal,
So as to play the effect for increasing extra large thickness of pipe wall indirectly, or it is the thicker extra large pipe pipe nipple of one section of wall thickness, is directly docked with common extra large pipe.
The buckle arrestor of welded type or monoblock type, all there is at sea construct when installation difficulty the problem of.Due to being required for welding with extra large pipe
Connect, and the work such as follow-up nondestructive testing, anti-corrosion, a large amount of manpowers and material are not only expended, and it is quite time-consuming.
Utility model content
For technological deficiency present in above-mentioned prior art, the utility model provides a kind of Submarine Pipeline of Fast Installation
Road buckle arrestor.
To realize the purpose of this utility model, the utility model provides a kind of submarine pipeline bending arrestor of Fast Installation,
Including 2 chip size identical half-watts, the both sides of every half-watt extend outward one block of web respectively, and bolt passes through 2 half-watt abdomens
Fixing hole on plate, 2 half-watt webs are fastenedly connected.
Compared with prior art, the beneficial effects of the utility model are that simple and reliable for structure, assembling is convenient, comprehensive to make
Cost is lower, it is possible to achieve the Fast Installation in construction, and once success rate is close to 100%, higher than other forms
Buckle arrestor, taken so as to effectively reduce ship, reduce integral construction expense.
Brief description of the drawings
Fig. 1 show the schematic diagram of apparatus structure first of the application；
Fig. 2 show the schematic diagram of apparatus structure second of the application.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., both it was directly connected to including a certain part and another part, and also passed through miscellaneous part and another portion including a certain part
Part is connected.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As shown in Figure 1 and Figure 2, the main part of buckle arrestor for left and right 2 chip size identical half-watts 1, the two of every half-watt 1
Epitaxial lateral overgrowth stretches out one block of web 4, and blending bolt 5 is fastened, reinforced between web 4 and half-watt 1 using reinforcement 6.In order to
It is easy to the installation of buckle arrestor, every half-watt 1 is welded with a hanger 7 near center line.Sheet material selects Aldecor material.
The side of 2 half-watts 1 is hinged by bearing pin 2 so that half-watt 1 can be around the folding of bearing pin 2.The inner side of every half-watt 1
It is lined with the rubber layer 3 that thickness is about 3.0mm.And it is welded with a copper conductor 8, the other end of copper conductor 8 on wherein a piece of half-watt 1
It will be connected when buckle arrestor is installed with extra large pipe body.
The application has abandoned traditional welding manner, but use clamp type in the mode being connected with submarine pipeline
Mechanical connection manner.The side of 2 half-watts 1 is hinged by bearing pin 2 on buckle arrestor so that half-watt 1 can be around bearing pin 2
Folding.In transport, storing process, 2 half-watts 1 of buckle arrestor keep being close together.When installing at the construction field (site), first will
Buckle arrestor is opened, and is reused crane gear and is sling by the hanger 7 on buckle arrestor and move close to extra large pipe body, then will
Buckle arrestor closes, and puts on bolt 5 and is reinforced using hydraulic spanner, the gap between 2 half-watts 1 can ensure the pretension of bolt 5
Power can be effectively passed on half-watt 1.The inner side of every half-watt 1 is lined with rubber layer 3, plays increase contact area, disperses pressure,
The effect for preventing extra large pipe corrosion-inhibiting coating to be subject to crushing.Finally the other end of copper conductor on buckle arrestor 8 is connected with extra large pipe, so as to
Cathodic protection is formed to buckle arrestor using the anode on extra large pipe, extends buckle arrestor service life.
Described above is only preferred embodiment of the present utility model, it is noted that for the general of the art
For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change
Enter and retouch and also should be regarded as the scope of protection of the utility model.
