Abstract
The invention relates to an improved gas drainage pipe, which comprises a pipeline body, wherein the outer wall of the pipeline body is outwards raised to form a reinforcing rib with a double helix structure; the reinforcing rib and the pipeline body form an integrated structure. According to the improved gas drainage pipe, the self weight of the pipe can be reduced, and the strength of the pipe is strengthened.
Description
Technical field
The invention belongs to gas extraction tubing, particularly a kind of double-helical gas drainage pipe.
Background technique
Current known coal mine gas drainage pipe has: the most frequently used common steel tube, in order to guarantee pipeline, certain intensity is arranged, and steel pipe must have certain thickness, and the steel pipe weight is not easy to construction; Underground mine use glass fibre reinforced plastics gas releasing pipe, underground mine use polyethylene gas drainage pipe, underground mine use Steel Skeleton polyethylene gas drainage pipe etc.If it is heavier that these several pipeline wall thickness are conducted oneself with dignity, construction inconvenience; If, there is potential safety hazard in the thin easy distortion of wall.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of gas drainage pipe of improvement, is provided with the stiffening rib of double helical form, can alleviate the weight of pipeline self, has increased again its intensity.
For solving the problems of the technologies described above, technological scheme of the present invention is:
A kind of gas drainage pipe of improvement, comprise pipeline body, and wherein, described pipeline body outer wall is the double-stranded stiffening rib of outstanding formation outwards, and described stiffening rib and pipeline body are the integral type structure.
The gas drainage pipe of above-mentioned a kind of improvement, wherein, described stiffening rib forms double-spiral structure axisymmetricly.
The gas drainage pipe of above-mentioned a kind of improvement, wherein, described stiffening rib cross section is isosceles trapezoid.
The gas drainage pipe of above-mentioned a kind of improvement, wherein, isosceles trapezoid two drift angles that described stiffening rib cross section forms are circular-arc, and base length is 30mm, and height is 14mm, and two base angles are 43 °.
The gas drainage pipe of above-mentioned a kind of improvement, wherein, described stiffening rib cross section is circular arc, and as optimization, the radius of arc that described stiffening rib cross section forms is 15-20mm.
Beneficial effect of the present invention is:
1. the stiffening rib in this structure is double helix, has greatly increased the anti-pressure ability of body, and body toughness increases, and has alleviated the quality of body, reduced cost, and double-spiral structure is more stable, can effectively prevent that body from rolling, and makes transportation etc. convenient.
2. the stiffening rib cross section is isosceles trapezoid or circular arc, can better disperse filling pressure thereon, stressed more even; The drift angle of its circular arc has played protective action, can prevent from scratching external equipment or operator, and Security is higher.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present invention
The sectional view that Fig. 2 is stiffening rib of the present invention (trapezoidal)
The sectional view that Fig. 3 is stiffening rib of the present invention (circle)
Embodiment
Example one
A kind of gas drainage pipe of improvement as shown in Figure 1 and Figure 2, comprise pipeline body 1, pipeline body 1 outer wall is the double-stranded stiffening rib 2 of outstanding formation outwards, and stiffening rib 2 forms double-spiral structures axisymmetricly, and described stiffening rib 2 is the integral type structure with pipeline body 1; The stiffening rib cross section is isosceles trapezoid, makes its two drift angle 3 for circular-arc, and base length is 30mm, and height is 14mm, and two base angles are 43 °.
Example two
A kind of gas drainage pipe of improvement as shown in Figure 1, Figure 3, comprise pipeline body 1, pipeline body 1 outer wall is the double-stranded stiffening rib 2 of outstanding formation outwards, and stiffening rib 2 forms double-spiral structures axisymmetricly, and described stiffening rib 2 is the integral type structure with pipeline body 1; Stiffening rib 2 cross section semicirculars in shape, its radius R is 15mm.
Stiffening rib in this structure is double helix, has greatly increased the anti-pressure ability of body, has alleviated the quality of body, has reduced cost, and double-spiral structure is more stable, can effectively prevent that body from rolling, and makes transportation etc. convenient.The stiffening rib cross section is isosceles trapezoid, can better disperse filling pressure thereon, stressed more even; The drift angle of its circular arc has played protective action, can prevent from scratching external equipment or operator, and Security is higher.
Here description of the invention and application is illustrative, not wants that therefore, the present invention is not subject to the restriction of the present embodiment by scope restriction of the present invention in the above-described embodiments, and the technological scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
