Description
Technical Field
The invention relates to the technical field of pipes, in particular to a high-ring-stiffness hot-state winding structure wall pipe.
Background
The hot winding structure wall pipe (carat pipe) in the current market adopts the structure in fig. 3, uses a corrugated pipe with a circular cross section as an inner support, adopts an outer coating layer made of polyethylene or polypropylene as a reinforcing structure, and is fused with the inner wall in a molten state which is previously wound on a forming die to form the pipe, and the pipe is shown in fig. 4. The structure has the advantages that the circular corrugated pipe is easy to process and manufacture, and the defect that the pipe wall structure cannot exert the maximum performance of the material in terms of mechanical properties. When external force acts on the upper part of the whole pipe, the outer wall of the pipe is coated with the round pipe, and because the round pipe is a round pipe, the coated round pipe and the inner wall only have small contact surfaces, the pipe wall below the radius of the round pipe cannot immediately transmit force to the whole pipe body through the inner wall of the large pipe when the external force is applied, only when the coated round pipe is stressed to generate certain deformation, and the rebound force generated by the deformation is greater than the external acting force, the force can be transmitted to the whole pipe body through the inner wall of the pipe. Thus, to increase the ring stiffness of the entire pipe, the cladding must be thickened, and the weight and cost of the pipe are greatly increased.
Therefore, it is an urgent technical problem to be solved by those skilled in the art to provide a thermal winding structural wall pipe which not only can improve the ring stiffness of the pipe, but also can reduce the weight and cost of the pipe.
Disclosure of Invention
In view of the above, the present invention provides a hot-state winding structure wall pipe with high ring stiffness.
In order to solve the technical problems, the invention adopts the following technical scheme:
a high-ring-stiffness thermal-state winding structure wall pipe comprises a pipe body and a winding wall pipe wound on the outer wall of the pipe body, wherein the winding wall pipe is welded on the outer wall of the pipe body; the winding wall pipe is sequentially provided with a coating layer and a corrugated pipe from outside to inside; the top of the wrapping layer is of an arch structure;
the side walls on the two sides of the wrapping layer and the outer wall of the pipe form a certain angle a.
Preferably, the wrapping layer is made of polyethylene or polypropylene material.
Preferably, the corrugated pipe is a polypropylene corrugated pipe.
Preferably, the angle a formed between the side walls on the two sides of the wrapping layer and the outer wall of the pipe is 90-110 degrees.
Preferably, the angle a formed between the side walls on the two sides of the wrapping layer and the outer wall of the pipe is 92 degrees.
Compared with the prior art, the invention has the following technical effects:
according to the invention, the top of the coating layer is arched, and two side walls of the coating layer form a certain angle with the outer wall of the pipe. From the aspect of mechanical properties of materials, when the side wall of the wrapping layer is perpendicular to the outer wall of the pipe, the pressure borne by the side wall is the largest, but the controllability in the production process, the stability of a product and the controllability for solving the deformation direction of the side wall after stress are considered, so that the side wall is designed to form a certain angle with the inner wall of the pipe, and the angle cannot be too large, so that the side wall is stressed to bend and deform. Therefore, the angle is controlled between 90 degrees and 110 degrees, and through the design, the internal reaction force generated by the side wall of the wrapping layer is far greater than the generated bending force when the external force is applied; in addition, because the thickness of the top of the wrapping layer is greater than the thickness of the side walls on the two sides, when the whole pipe is subjected to external pressure on the upper surface, the top is stressed firstly and is stressed maximally, the force is dispersed to the two side walls, and then the force is directly transmitted to the whole pipe body through the outer wall of the pipe;
therefore, the thermal winding structure wall pipe not only can ensure that the pipe has excellent ring rigidity and gives full play to the performance of materials, but also can reduce the weight and the cost of the pipe.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
Referring to fig. 1 and 2, a high ring stiffness hot winding structural wall pipe comprises a pipe material and a winding wall pipe 1 wound on the outer wall of the pipe material, wherein the winding wall pipe 1 is welded on the outer wall 105 of the pipe material; the winding wall pipe 1 is provided with a coating layer 101 and a corrugated pipe 102 from outside to inside in sequence; the top 103 of the wrapping layer 101 is arranged to be an arch structure; the side walls 104 on both sides of the wrapping 101 are at an angle a to the outer wall 105 of the tubing.
In some embodiments, wrapping 101 is made from a polyethylene or polypropylene material.
In some embodiments, bellows 102 is a polypropylene bellows.
In some embodiments, the sidewalls 104 on both sides of the wrapping 101 are angled at an angle a of 90 ° to 110 ° to the outer wall 105 of the tubing.
In some embodiments, the side wall 104 of the wrapping 101 is at an angle a of 92 ° to the outer wall 105 of the tubing.
In some embodiments, the thickness of top 103 of wrapping layer 101 is greater than the thickness of sidewalls 104 on both sides thereof.

In other embodiments, the side wall 104 of the wrapping 101 is at an angle a of 100 ° to the outer wall 105 of the tubing.
In other embodiments, the side wall 104 of the wrapping 101 is at an angle a of 110 ° to the outer wall 105 of the tubing.
According to the invention, the top of the coating layer is arched, and two side walls of the coating layer form a certain angle with the outer wall of the pipe. From the aspect of mechanical properties of materials, when the side wall of the wrapping layer is perpendicular to the outer wall of the pipe, the pressure borne by the side wall is the largest, but the controllability in the production process, the stability of a product and the controllability for solving the deformation direction of the side wall after stress are considered, so that the side wall is designed to form a certain angle with the inner wall of the pipe, and the angle cannot be too large, so that the side wall is stressed to bend and deform. Therefore, the angle is controlled between 90 degrees and 110 degrees, and through the design, the internal reaction force generated by the side wall of the wrapping layer is far greater than the generated bending force when the external force is applied; in addition, because the thickness of the top of parcel layer is greater than the thickness of the lateral wall of both sides, consequently, when whole pipe received the above-mentioned external pressure, the top atress was first atress and atress is the biggest, can disperse the both sides wall with power, and then directly transmits whole pipe shaft with the outer wall of power through tubular product.
