Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of polymer pipes, and particularly relates to a double high - rib reinforced polyethylene winding pipe. Background Art
[0002] In order to enhance the ring stiffness, the existing double high - rib reinforced polyethylene winding pipe synchronously embeds winding steel wires in the winding strip of the pipe. This structure not only increases the complexity and cost of the mold, but also makes the production process relatively complex. Moreover, the weld seam after fusion welding is straight, and the axial anti - traction ability is relatively weak. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a double high - rib reinforced polyethylene winding pipe.
[0004] The technical solution of the utility model is as follows:
[0005] A double high - rib reinforced polyethylene winding pipe is formed by spiral winding and fusion welding of a first winding strip and a second winding strip. The middle of the cross - section of the first winding monomer is a straight section, and the upper sides at both ends of the straight section are "n" - shaped protrusions. After the first winding strip is spirally wound, the adjacent "n" - shaped protrusions are fusion - welded into "m" - shaped protrusions, and one or more steel wires are evenly wound around the top of the "m" - shaped protrusions; the cross - section of the second winding strip is fan - shaped, and it covers and fusion - welds the steel wires along the top of the "m" - shaped protrusions, thus forming an arch - shaped double high - rib together with the "m" - shaped protrusions; the straight sections after fusion welding form the pipe wall.
[0006] Further, there are two steel wires, which are symmetrically arranged.
[0007] Further, the top of the "n" - shaped protrusion is a relatively gentle arc.
[0008] Further, the first winding strip is made of polyethylene, and the material of the second winding strip is different from that of the first winding strip.
[0009] Further, the first winding strip and the second winding strip have different colors.
[0010] Further, steel wires are respectively embedded at the joints of the "n" - shaped protrusions and the straight sections.
[0011] The advantages of the utility model are as follows:
[0012] The difference between the present utility model and the prior art is that the steel wire is not embedded in the first winding tape, but is evenly wound around the top of the "m"-shaped protrusion, and then added to the pipeline by covering the steel wire winding and fusion welding along the top of the "m"-shaped protrusion through the second winding tape. This method greatly reduces the complexity and cost of the mold, reduces the difficulty of the production process, and compared with the structure in the prior art where two "n"-shaped protrusions are directly butted to form an arch-shaped protrusion, the weld seam presents a T shape, and the anti-traction strength in the horizontal direction is stronger.

[0015] Figure 3 is a schematic cross-sectional view of the first winding tape.
[0016] In the figure: 1 - pipe wall, 2 - arch-shaped double high ribs, 3 - first winding tape, 31 - straight section, 32 - "n"-shaped protrusion, 4 - "m"-shaped protrusion, 5 - steel wire, 6 - second winding tape, 7 - weld seam. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further describes the specific embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0018] As Figures 1-3 shown:
[0019] A double high rib reinforced polyethylene winding pipe is formed by helically winding and fusion welding the first winding tape 3 and the second winding tape 6. The middle of the cross-section of the first winding monomer is a straight section 31, and the upper sides of both ends of the straight section 31 are "n"-shaped protrusions 32. After the first winding tape 3 is helically wound, the adjacent "n"-shaped protrusions 32 are fusion welded into an "m"-shaped protrusion 4, and one or more steel wires 5 are evenly wound around the top of the "m"-shaped protrusion 4. It is recommended to use two, and symmetric arrangement is sufficient. In order to facilitate the winding of the steel wire 5, the top of the "n"-shaped protrusion 32 is a relatively gentle arc.
[0020] The cross-section of the second winding tape 6 is fan-shaped, and it covers and fusion welds the steel wire 5 along the top of the "m"-shaped protrusion 4, so as to form an arch-shaped double high rib 2 with the "m"-shaped protrusion 4, and the welded straight section 31 forms part of the pipe wall 1.
[0021] The difference between the present utility model and the prior art is that the steel wire 5 is not embedded in the first winding tape 3, but is evenly wound around the top of the "m"-shaped protrusion 4, and then added to the pipeline by covering the steel wire 5 wound and fusion-welded along the top of the "m"-shaped protrusion 4 through the second winding tape 6. This method greatly reduces the complexity and cost of the mold, reduces the difficulty of the production process, and compared with the structure in the prior art where two "n"-shaped protrusions 32 are directly butted to form the arch-shaped double high ribs 2, the weld seam 7 presents a T shape, and the anti-traction strength in the horizontal direction is stronger.
[0022] As an optimized solution, the first winding tape 3 and the second winding tape 6 are made of different materials. The first winding tape 3 is made of polyethylene material, and the second winding tape 6 is different from the material of the first winding tape 3. The second winding tape 3 is located outside, and other materials can be selected for wear resistance, etc. Different materials may cause color differences, so the first winding tape 3 and the second winding tape 6 may have different colors, which is also convenient for distinguishing from ordinary pipes of the same type because the appearance is not very different.
[0023] As an optimized solution, steel wires 5 are respectively embedded at the joints between the "n"-shaped protrusions 32 and the straight sections 31 because the wall thickness at the joints is relatively large and the difficulty of embedding the steel wires is relatively small.
[0024] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
