[0028] EMBODIMENT

[0029] As mentioned in the background, the existing plastic pipe can meet the normal conveying medium demand when in use, but the support strength of the external spiral rib is poor, and the spiral rib itself is very easy to deform, which leads to the pipe being very easy to be damaged. Therefore, the inventor improves the existing high-cavity pipe and designs a pipe with a new reinforcing rib 2, which will be described in detail below in combination with the drawings.

[0030] The present embodiment provides an AT-SW anti-dropping high-cavity pipe. It should be noted that AT (i.e., "antioxidant") means that the pipe as a whole adopts an antioxidant material, and SW means that the pipe is provided with a steel wire 5 at some local positions. SW means that the structure of each strand is Seale-Warrington composite type, in which S means Seale, i.e., the outer layer of steel wire adopts a structure of coarse-thin alternating arrangement, and each coarse steel wire is filled with fine steel wires around to enhance wear resistance, and W means Warrington, i.e., the inner layer of steel wire is alternately woven by steel wires of different diameters to improve flexibility and fatigue resistance. See Figure 1 The present scheme includes a main pipe 1 made by embedding and hot-melting adhesion, which can be made by using the existing technology. The outer edge surface of the main pipe 1 is provided with a plurality of groups of reinforcing ribs 2 arranged at intervals, and the plurality of groups of reinforcing ribs 2 are integrally formed and spirally fixed around the main pipe 1. Although the reinforcing ribs 2 are spirally wound to form a plurality of groups of reinforcing ribs 2, the plurality of groups of reinforcing ribs 31 still belong to one, and the reinforcing ribs 2 are wound on the outer edge surface of the main pipe 1 by an extruder, a press roller and the like.

[0031] In the present embodiment, the reinforcing rib 2 is combined with Figure 2 and Figure 3, next to each group of reinforcing ribs 2 are described separately, but not affect the overall spiral integral molding, wherein each group of the reinforcing ribs 2 are connected with the main pipe 1 reinforcing bottom plate 21, reinforcing bottom plate 21 with the pipe main body using hot melt adhesive form, reinforcing bottom plate 21 both ends are provided with two first reinforcing rib 22, with the first reinforcing rib 22 integral molding, the first reinforcing rib 22 with the main pipe 1 using vertical way is arranged, and two first reinforcing rib 22 side close to each other are integrally formed with arc rib 23, arc rib 23 from the first reinforcing rib 22 bending to the direction of the main pipe 1, by setting arc rib 23, can improve the reinforcing rib 2 and the buffer effect produced when extruding.

[0032] On the basis of the above structure, the arc rib 23 away from the first reinforcing rib 22 one end integral molding has the second reinforcing rib 24, and the second reinforcing rib 24 extends to the reinforcing bottom plate 21 and is fixed thereto, and the second reinforcing rib 24 is inclined to set, and the bottom end of the two second reinforcing rib 24 of the same group is inclined inward, that is, the bottom end of the two second reinforcing rib 24 of the same group is inclined to the direction of approaching each other, which improves the anti deformation ability of itself and avoids excessive bending phenomenon when pressure is applied.

[0033] In this embodiment, the reinforcing bottom plate 21 between the adjacent second reinforcing rib 24 is fixed with a support layer 4, where the adjacent second reinforcing rib 24 refers to the two second reinforcing rib 24 of the same group of reinforcing ribs 2, the support layer 4 is adhesively fixed with the reinforcing bottom plate 21, and the cross sectional shape thereof is semicircular. By providing the support layer 4, the strength of the reinforcing bottom plate 21 between the two second reinforcing rib 24 can be improved, and the thickness of the support layer 4 is 2-3 times the thickness of the reinforcing bottom plate 21, avoiding the phenomenon that the traditional substrate is too weak and easy to break, and increasing the protection effect.

[0034] It should be noted that in combination Figure 3 , the reinforcing bottom plate 21 is embedded with steel wire 5, the steel wire 5 is spirally formed in the reinforcing bottom plate 21, and the steel wire 5 in the reinforcing bottom plate 21 is located at the corresponding position of the cavity formed by the first reinforcing rib 22, the arc rib 23 and the second reinforcing rib 24, and is located on both sides of the support layer 4, staggered arrangement, further increasing the supporting effect of the steel wire 5.

[0035] On the basis of the above structure, due to the spiral forming, there is a gap between the two adjacent groups of reinforcing ribs 2, in order to make up for the gap, so that the adjacent reinforcing ribs 2 support each other, the reinforcing assembly 3 is spirally fixed on the outer edge surface of the main pipeline 1, and the reinforcing assembly 3 successively passes through the two adjacent reinforcing ribs 2 and is fixed with them, that is, one side of the reinforcing assembly 3 passes through the gap between the adjacent reinforcing ribs 2, specifically, the reinforcing assembly 3 includes reinforcing ribs 31 located between the two adjacent groups of reinforcing ribs 2, and the reinforcing ribs 31 are adhesively fixed with the two sides of the first reinforcing ribs 22, so that the two sides of the first reinforcing ribs 22 form mutual support, and the reinforcing ribs 31 are adhesively fixed with the main pipeline 1, secondly, a plurality of release holes 33 are formed in the reinforcing ribs 31 along the length direction, by forming the release holes 33, a part of the stress generated when being extruded can be released.

[0036] In addition, the length of the reinforcing rib 31 in the scheme is less than the length of the reinforcing rib 2, therefore, a protective layer 32 is arranged on the side of the reinforcing rib 31 away from the main pipeline 1, and the protective layer 32 is fixed with the reinforcing rib 31 and the two first reinforcing ribs 22 respectively, and the protective layer 32 is embedded with a steel wire 5, which improves the overall strength and anti-deformation ability of the protective layer 32.
