Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel pipe, especially a steel pipe packaging structure. BACKGROUND

[0002] At present, there are plastic coated pipes for conveying natural gas, gas, biogas, coal gas and the like. Among them, the existing plastic coated pipe is fused with a protective layer with a thickness of 0.5-1mm on the inner and outer surfaces of the steel pipe. Since the existing protective layer is mostly composed of polyethylene (PE) resin, ethylene-acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and the like, and the thickness of the protective layer is relatively thin, the wear and scratch resistance of the protective layer is relatively low.

[0003] In addition, when the plastic coated pipe is packaged, it is mostly bundled together by steel bands. In order to ensure the stability of the packaging, the steel bands are mostly in a relatively tight bundling state, so that there is a relatively large force between the steel bands and the plastic coated pipe, and in addition, the side edges of the steel bands are generally relatively sharp, which is easy to scratch the protective layer during packaging and transfer. In addition, such packaging is easy to have a relatively large friction between adjacent plastic coated pipes, which is easy to cause wear of the protective layer. This will cause the protective performance of the protective layer to decrease.

[0004] At the same time, when the plastic coated pipe is packaged, the port of the plastic coated pipe is mostly directly in an open state, so that water vapor, dust, mosquitoes and the like are easy to enter the plastic coated pipe through the port of the plastic coated pipe, which will cause the protective layer on the inner wall of the plastic coated pipe to be contaminated, and even the aging speed to be accelerated, and once the pipe body is contaminated or aged too much, it is very difficult to clean and maintain.

[0005] Therefore, it is necessary to design a steel pipe packaging structure that can solve the above technical problems. SUMMARY

[0006] The utility model discloses a steel pipe packaging structure that can well protect the protective layer on the inner and outer surfaces of the plastic coated pipe, which can greatly reduce the probability of the protective layer being worn, scratched, contaminated and aged too fast, and can not only ensure that the protective layer in use has very high protective performance, but also reduce the probability of cleaning and maintenance before use, and has the advantages of high packaging quality, stable packaging and strong applicability.

[0007] The technical scheme of the utility model is implemented as follows:

[0008] The utility model provides a steel pipe packaging structure, its characterized in being including steel pipe stack, at least one sheet of isolation sheet, at least one binding belt, wherein steel pipe stack includes a plurality of plastic coated steel pipes, and the outer wall of each plastic coated steel pipe is wrapped with protective film, and the port of each plastic coated steel pipe is embedded with shielding cover, the isolation sheet is wrapped on the end of steel pipe stack, and the binding belt is sleeved on the isolation sheet and makes the end of steel pipe stack be tied by the binding belt.

[0009] Preferably, the isolation sheet is an isolation cloth sheet, an isolation plastic sheet, an isolation non-woven fabric sheet or an isolation rubber sheet.

[0010] Preferably, the binding belt is a steel binding belt.

[0011] Preferably, the protective film is a polyethylene protective film.

[0012] Preferably, the outer wall of the shielding cover is provided with a ventilation hole communicated with the inner hole of the plastic coated steel pipe, and a breathable sponge block is embedded in the ventilation hole.

[0013] Preferably, the shielding cover is a cylindrical closed cover with one end closed, the ventilation hole is formed through the closed end of the shielding cover, and the closed end of the shielding cover faces the middle part of the plastic coated steel pipe.

[0014] Preferably, a guide arc surface is formed on the outer side of the closed end of the shielding cover.

[0015] Preferably, a convex pipe part is arranged on the outer wall of the closed end of the shielding cover, and the inner hole of the convex pipe part constitutes the ventilation hole.

[0016] Preferably, a positioning convex ring is arranged on the outer circumferential surface of the open end of the shielding cover, the positioning convex ring abuts against the end face of the plastic coated steel pipe, a steel cylinder is embedded in the cylindrical part of the shielding cover, a steel ring is embedded in the positioning convex ring, and the inner end of the steel ring is arc transitionally connected with the end part of the steel cylinder.

[0017] Preferably, the ventilation hole is a hole structure with narrow two ports and large interior.

[0018] The utility model discloses a steel pipe packaging structure, its characterized in being including steel pipe stack, at least one sheet of isolation sheet, at least one binding belt, wherein steel pipe stack includes a plurality of plastic coated steel pipes, and the outer wall of each plastic coated steel pipe is wrapped with protective film, and the port of each plastic coated steel pipe is embedded with shielding cover, the isolation sheet is wrapped on the end of steel pipe stack, and the binding belt is sleeved on the isolation sheet and makes the end of steel pipe stack be tied by the binding belt, which can avoid the direct contact between the binding belt and the plastic coated steel pipe, thereby effectively reducing the probability of scratches on the protective layer outside the plastic coated steel pipe.

[0019] By embedding the shielding cover on the port of the plastic coated steel pipe, the shielding cover can shield the port of the plastic coated steel pipe, so that the probability of water vapor, dust, mosquitoes and the like entering the plastic coated steel pipe can be reduced, thereby the probability of the protective layer on the inner wall of the plastic coated steel pipe being contaminated can be reduced, and then the aging speed can be reduced, so that the probability of cleaning and maintenance before use can be reduced.

[0020] Therefore, the steel pipe packaging structure can well protect the protective layer on the inside and outside of the plastic coated pipe, which can greatly reduce the probability of the protective layer being damaged, scratched, contaminated, and having an excessively large aging speed, and can not only help to ensure that the protective layer in the use state has very high protection performance, but also can reduce the probability of cleaning and maintenance before use, and has the advantages of high packaging quality, stable packaging, strong applicability and the like.

[0025] As shown in Figures 1 to 3 The utility model discloses a steel pipe packaging structure, including steel pipe pile 1, at least one sheet of isolation sheet 2, at least one strip of binding tape 3, wherein steel pipe pile 1 includes several plastic coated steel pipes 11, and the outer wall of each plastic coated steel pipe 11 is wrapped with protective film 12, and each plastic coated steel pipe 11 is embedded with shielding cover 4 on the port, isolation sheet 2 is wrapped on the end of steel pipe pile 1, and binding tape 3 is sleeved on isolation sheet 2, and the end of steel pipe pile 1 is bound by binding tape 3.

[0026] On the steel pipe packaging structure, by wrapping the protective film 12 on the outer wall of the plastic coated steel pipe 11, the protective film 12 can shield and protect the protective layer on the outer wall of the plastic coated steel pipe 11, which can effectively reduce the probability of wear of the protective layer on the plastic coated steel pipe 11; the isolation sheet 2 is wrapped around the end of the steel pipe stack 1, and the bundling belt 3 is sleeved on the isolation sheet 2, and the bundling belt 3 is bundled to the end of the steel pipe stack 1, which can avoid the bundling belt 3 directly contacting the plastic coated steel pipe 11, which can effectively reduce the probability of scratching the protective layer on the plastic coated steel pipe 11; therefore, such a steel pipe packaging structure can greatly reduce the probability of wear and scratching of the protective layer of the plastic coated steel pipe 11, thereby avoiding the accumulation of the protective performance of the protective layer.

[0027] By embedding the shielding cover 4 on the port of the plastic coated steel pipe 11, the shielding cover 4 can shield the port of the plastic coated steel pipe 11, which can reduce the probability of water vapor, dust, mosquitoes and the like entering the plastic coated steel pipe 11, thereby reducing the probability of the protective layer on the inner wall of the plastic coated steel pipe 11 being contaminated, and thereby reducing the aging speed, which can reduce the probability of cleaning and maintenance before use.

[0028] Therefore, the steel pipe packaging structure can well protect the protective layer inside and outside the plastic coated pipe, which can greatly reduce the probability of adverse conditions such as wear, scratching, contamination, and excessive aging speed of the protective layer, which not only can help to ensure that the protective layer in use has very high protective performance, but also can reduce the probability of cleaning and maintenance before use, which has the advantages of high packaging quality, stable packaging, strong applicability, etc.

[0029] The isolation sheet 2 is an isolation cloth sheet, an isolation plastic sheet, an isolation non-woven fabric sheet or an isolation rubber sheet. This not only can facilitate the wrapping of the isolation sheet 2 on the steel pipe stack 1, but also can have very good isolation effect, thereby helping to further improve the reliability and applicability of the steel pipe packaging structure.

[0030] The isolation sheet 2 can wrap the end of the steel pipe stack 1, which can shield and protect the end of the plastic coated steel pipe 11 to reduce the probability of the port of the plastic coated steel pipe 11 being damaged by collision.

[0031] The bundling belt 3 is a bundling steel belt. This can make the bundling belt 3 have high structural strength and durability, thereby helping to improve the stability and safety of the steel pipe packaging.

[0032] The protective film 12 is a polyethylene (PE) protective film. This can make the protective film 12 have good flexibility and wear resistance, which not only can facilitate the wrapping of the protective film 12, but also can make the protective film 12 have very stable and reliable protective effect, thereby helping to further improve the reliability and applicability of the steel pipe packaging structure.

[0033] As Figure 3 AndFigure 4 As shown in the figure, the outer wall of the shielding cover 4 is provided with a ventilation hole 41 communicated with the inner hole of the plastic coated steel pipe 11, and a breathable sponge block 5 is embedded in the ventilation hole 41. The ventilation hole 41 can meet the ventilation requirement, which can facilitate the installation and disassembly of the shielding cover 4. The breathable sponge block 5 embedded in the ventilation hole 41 can not only meet the ventilation requirement, but also effectively seal the plastic coated steel pipe 11, which can greatly reduce the probability of water vapor, dust, mosquitoes and other things entering the plastic coated steel pipe 11, thereby greatly reducing the probability of damage and accelerated aging of the inner wall of the plastic coated steel pipe 11, and further eliminating the need for cleaning and maintenance before use, which can improve the installation and use efficiency.

[0034] The shielding cover 4 is made of plastic, which can facilitate manufacturing, embedding and disassembly, and the shielding cover 4 can be reused, thereby ensuring that the steel pipe packaging structure has high applicability.

[0035] As shown in the figure, Figure 3 As shown in the figure, Figure 4 The shielding cover 4 is a cylindrical closed cover with one end closed, the ventilation hole 41 is provided through the closed end of the shielding cover 4, and the closed end of the shielding cover 4 faces the middle part of the plastic coated steel pipe 11. In this way, the shielding cover 4 has sufficient embedding amount, and the port of the ventilation hole 41 is located on the inner side of the shielding cover 4, which can greatly reduce the probability of rainwater entering the ventilation hole 41, thereby improving the sealing effect of the shielding cover 4.

[0036] As shown in the figure, Figure 4 The outer side of the closed end of the shielding cover 4 is provided with a guide arc surface 42. In this way, the closed end of the shielding cover 4 has a structure with a small outer end and a large inner end, which can facilitate the embedding of the shielding cover 4 into the port of the plastic coated steel pipe 11, thereby improving the installation convenience.

[0037] As shown in the figure, Figure 3 As shown in the figure, Figure 4 The closed end of the shielding cover 4 is provided with a convex pipe portion 43, and the inner hole of the convex pipe portion 43 constitutes the ventilation hole 41. The convex pipe portion 43 can provide more sufficient installation space for the breathable sponge block 5 without adding other structures, thereby facilitating the use of longer breathable sponge block 5, and further improving the protection performance of the steel pipe packaging structure; and in this way, the convex pipe portion 43 is located in the plastic coated steel pipe 11, which will not affect the normal storage and transfer of the plastic coated steel pipe 11, thereby further improving the reliability and applicability of the steel pipe packaging structure.

[0038] As shown in the figure, Figure 3 As shown in the figure, Figure 4As shown in the drawings, the outer circumferential surface of the opening end of the shielding cover 4 is provided with a positioning convex ring 44 which is abutted against the end face of the plastic coated steel pipe 11; a steel cylinder 46 is embedded in the barrel part 45 of the shielding cover 4, a steel ring 47 is embedded in the positioning convex ring 44, and the inner end of the steel ring 47 is arc transitionally connected with the end part of the steel cylinder 46. The positioning convex ring 44 not only can enhance the protection effect, but also can achieve the purpose of accurately positioning the shielding cover 4, so as to facilitate the quick and stable installation of the shielding cover 4 in place, and further help to improve the reliability and applicability of the steel pipe packaging structure. The steel cylinder 46 and the steel ring 47 can greatly enhance the structural strength of the shielding cover 4, which not only can avoid the damage of the shielding cover 4 in the disassembly process, but also can enhance the compression resistance of the end port of the plastic coated steel pipe 11, so as to avoid the deformation of the end port of the plastic coated steel pipe 11, and further help to improve the reliability and applicability of the steel pipe packaging structure.

[0039] As shown in the drawings, Figure 4 The positioning convex ring 44 is provided with a guide inclined surface 441 near the top edge of the plastic coated steel pipe 11. This can facilitate the insertion of a disassembly tool between the positioning convex ring 44 and the plastic coated steel pipe 11, so that the shielding cover 4 can be separated from the plastic coated steel pipe 11 by pressing the positioning convex ring 44 with the disassembly tool, and further improve the convenience of disassembly.

[0040] As shown in the drawings, Figure 4 The air vent hole 41 is a hole structure with narrow two ports and large internal diameter. Such air vent hole 41 can play a very stable and accurate positioning role on the breathable sponge block 5, so that the breathable sponge block 5 can play a more stable and reliable protection role, and further help to improve the reliability and applicability of the steel pipe packaging structure.

[0041] As shown in the drawings, Figure 1 As shown in the drawings, Figure 2 In the actual packaging process, the shielding cover 4 is embedded on both ends of the plastic coated steel pipe 11; the isolation sheet 2 is wrapped on both ends of the steel pipe stack 1, and at least one binding belt 3 is used to bind the two isolation sheets 2, so that the packaging requirement of the steel pipe can be stably achieved.
