Description
Technical field
The utility model relates to winding pipe construction applications more particularly to one kind to make somebody a mere figurehead counter-bending reinforced pipe.
Background technique
Winding pipe is a kind of higher reinforced tubing of intensity, by profile spiral winding, and heats and is spliced, due to weight
The advantages such as amount is light, production cost is low are widely used.In order to enhance winding pipe intensity, usually the cross section of profile can also be designed
Different shape out, to reach anti-extrusion, resist the effects of radial force.But when larger size winding pipe is used as cross-over pipe,
Such reinforced pipe is that bottom is hanging in installation, it is therefore desirable to bear biggish gravity.When reinforced pipe own wt is larger or pipeline
When the fluid weight inside passed through is larger, tube body can occur bending and deformation, and the bending of long-time or wide-angle gently then influences fluid
Flow efficiency, rupture that is heavy then will appear tube body, causes more serious problem.
A kind of radial corrugated pipe is disclosed in the Chinese utility model patent of Publication No. CN2851778Y, is managed by changing
Body cross-sectional shape increases the anti-bending strength of tube body, but this scheme will use more in the case where realizing same flow
Material, and by cross section be not it is round, be not available existing extrusion winding equipment and directly process.
Utility model content
The purpose of the utility model is to provide one kind to make somebody a mere figurehead counter-bending reinforced pipe, and tube body can be made to increase pipe in aerial situation
The anti-bending strength of body.
To achieve the goals above, the utility model provides the following technical solutions:
One kind making somebody a mere figurehead counter-bending reinforced pipe, including tube body and pull back device, and the tube body is formed by profile spiral winding, institute
Pull back device setting is stated in bottom, identical as tube body extending direction, pull back device includes being set to outermost enhancement layer.?
Bottom is provided with pull back device, hinders bending of the tube body on perpendicular, enhances the rigidity of tube body.And under tube body
Side is provided with pull back device, reduces the center of gravity of reinforced pipe, keeps the installation of reinforced pipe more stable, reduces the possibility of rolling.
Preferably, the enhancement layer is solid construction.Solid construction is easy to process, saves space.
Preferably, the enhancement layer is hollow structure, is internally provided with the cavity parallel with tube body extending direction.Hollow knot
Structure can increase the anti-bending strength of reinforced pipe using identical material.
Preferably, steel wire is provided in the enhancement layer.Increasing steel wire can be improved the intensity of pull back device, steel wire and bending resistance
Device extending direction is identical.
Preferably, protrusion is equipped on the outside of the profile, the protrusion forms spiral shape protrusion in tube surfaces.It has
The tube body of spiral shape protrusion can enhance anti-radial deformation capabilities.
Preferably, the pull back device further includes transition zone, and the transition zone is set between tube body and enhancement layer, transition
Layer side is adjacent to outer surface of tube body, and other side height is higher than spiral shape protrusion and connect with enhancement layer.Since tube surfaces are equipped with
Spiral shape protrusion, therefore simultaneously out-of-flatness, transition zone not only increase the integral thickness of pull back device, improve bending resistance effect, simultaneously
Also ensuring enhancement layer, cross section is constant in the direction of extension, is not required to make adaptation according to tube surfaces shape, ensure that enhancing
The bending resistance effect of layer is unaffected.
Preferably, the pull back device is multiple, and is symmetrical set along tube body extending direction.Tubing when aerial,
Although being influenced by gravity, it is likely that pull back device cannot be fully located at immediately below tube body in actual installation or tube body is real
Direction is not substantially vertical downward when the stress of border, therefore multiple pull back devices can more adapt to actual conditions, bending resistance effect
More preferably.
The utility model has the following beneficial effects:
1, enhancement layer is located at the outermost of reinforced pipe, and the setting after tube body is Wrapping formed enhances reinforced pipe as aerial
Bending resistance effect when pipe；
2, transition zone is applicable to the tube body that the tube surfaces such as bellows are provided with spiral shape protrusion；
3, hollow structure can be used in enhancement layer, increases the integral thickness of Anti-bending structure, and has saved using material, can mention
High bending resistance effect.
