Description

Technical Field

[0001] This application relates to the field of polyurethane composite pipe technology, and more particularly to an impact-resistant steel-lined polyurethane composite pipe. Background Technology

[0002] Impact-resistant steel-lined polyurethane composite pipe is a composite pipe made of steel pipe as the base material and high wear-resistant, high elasticity and high corrosion resistance polyurethane material as the inner lining, processed by special technology. It can be widely used in power, coal, mining, building materials, chemical and other industries to transport abrasive particulate materials and corrosive media such as coal powder, ash, mineral powder, aluminum liquid, mud and slurry.

[0003] Announcement No. CN222687502U discloses a multi-layer co-extruded PPR composite water supply pipe, comprising a composite water supply pipe including a wear-resistant and impact-resistant composite layer. A pressure-resistant and toughening composite layer is fixedly installed on the inner wall of the wear-resistant and impact-resistant composite layer. By setting the wear-resistant and impact-resistant composite layer and the pressure-resistant and toughening composite layer, the polyethylene and polyurethane wear-resistant layers on the wear-resistant and impact-resistant composite layer have good impact resistance, preventing the entire pipe from cracking when exposed to water flow or external impacts. It also has good wear resistance, improving the wear resistance of the entire composite water supply pipe and preventing leakage caused by external wear on the composite wear-resistant layer. The pressure-resistant and toughening composite layer has a good pressure-resistant and toughening effect, enabling the composite water supply pipe to withstand high water pressure without rupture, further improving the service life of the composite water supply pipe.

[0004] Existing polyurethane composite pipes generally lack protective structures, resulting in poor impact resistance. Accidental impacts during installation can damage the polyurethane composite pipes and cause unnecessary losses. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact-resistant steel-lined polyurethane composite pipe. This device aims to solve the problem that if the polyurethane composite pipe is accidentally impacted during installation, it will cause damage to the polyurethane composite pipe and result in unnecessary losses.

[0007] (2) Technical solution

[0008] To address the aforementioned technical problems, this utility model provides an impact-resistant steel-lined polyurethane composite pipe, comprising a composite pipe body, a protective shell on one side of the composite pipe body, and four spring chambers inside the protective shell. Each spring chamber contains a buffer spring, and the other end of each buffer spring is fixedly connected to a slider. The slider is slidably connected to the inner wall of the spring chamber, and a groove is formed on the bottom surface of the spring chamber. A sliding rod is slidably connected to the inner wall of the groove, and the other end of the sliding rod is fixedly connected to an arc-shaped support plate. The bottom surface of the arc-shaped support plate abuts against the side wall of the composite pipe body. By providing a protective shell, the composite pipe body is protected from direct impact. When the protective shell is impacted, the spring chambers inside the protective shell, through the cooperation of the slider, sliding rod, and arc-shaped support plate, provide a buffering effect on the impact force, preventing this impact force from hitting the composite pipe body, thus protecting the composite pipe body, preventing damage, improving the impact resistance of the composite pipe body, and having a simple structure and being easy to manufacture.

[0009] Furthermore, an anti-slip pad is provided at the connection between the arc-shaped support plate and the composite tube. By setting the anti-slip pad, the anti-slip property of the anti-slip pad allows the slide rod to better clamp the composite tube.

[0010] Furthermore, the bottom surface of the anti-slip mat has multiple grooves. By setting multiple grooves, the grooves will provide roughness to the contact surface between the anti-slip mat and the composite tube, thereby increasing the friction and providing stability for the anti-slip mat to hold the composite tube.

[0011] Furthermore, multiple buffer cottons are provided on one side of the arc-shaped support plate. By setting the buffer cottons, the buffer cottons will fill the remaining space on both sides of the arc-shaped support plate, and can provide a certain buffering force when the composite pipe is impacted and displaced, thus better protecting the composite pipe.

[0012] Furthermore, the outer side of the protective shell is wrapped with a buffer layer. By setting the buffer layer, a protective layer is formed on the outside of the protective shell, which further reduces the impact force generated by the impact.

[0013] Furthermore, one end of the protective shell is provided with multiple positioning holes, and the other end of the protective shell is fixedly connected with symmetrical positioning pins. By setting the positioning holes and positioning pins in cooperation, when installing the composite tube, the positioning pin on one side of the protective shell above the adjacent composite tube can be slid into the symmetrical positioning hole of the other protective shell, so that the two protective shells can be assembled, improving the convenience of installation.

[0014] Furthermore, a tapered guide head is fixedly connected to one end of the positioning pin. By setting the tapered guide head, the tapered guide head will provide a certain guiding effect for the positioning pin to slide into the positioning hole, which facilitates the connection of the pipeline.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By setting up a protective shell to provide a protective layer for the composite tube, considering the characteristics of polyurethane composite tubes, the design avoids direct impact to the composite tube. When the protective shell is impacted, the spring chamber inside the protective shell, through the cooperation of sliders, sliding rods, and arc-shaped support plates, provides a buffering effect on the impact force, preventing this impact force from hitting the composite tube, thus protecting the composite tube and preventing damage. This improves the impact resistance of the composite tube. The structure is simple and easy to manufacture. The cushioning cotton has a large number of micropores or fiber structures inside. When subjected to external impact, these structures can deform, absorb and disperse the impact energy, thereby effectively reducing damage to the protected object.

[0018] By incorporating a buffer layer, a protective layer is formed on the outside of the protective shell, further reducing the impact force generated by collisions. In addition to possessing the elasticity of rubber, it also exhibits excellent oil resistance. In the cushioning devices of mechanical equipment, if the working environment contains oil, the nitrile rubber buffer layer can be used for a long time without being corroded by oil, ensuring that the cushioning performance remains unaffected. Simultaneously, it also has good heat resistance and airtightness, making it suitable for applications requiring sealing and heat resistance. Attached Figure Description

[0027] This specific embodiment is an impact-resistant steel-lined polyurethane composite pipe, including a composite pipe body 1. A protective shell 2 is provided on one side of the composite pipe body 1, and four spring chambers 3 are provided inside the protective shell 2. A buffer spring 4 is provided inside the spring chamber 3, and a slider 5 is fixedly connected to the other end of the buffer spring 4. The slider 5 is slidably connected to the inner wall of the spring chamber 3, and a sliding groove 6 is provided on the bottom surface of the spring chamber 3. A sliding rod 7 is slidably connected to the inner wall of the sliding groove 6, and an arc-shaped support plate 8 is fixedly connected to the other end of the sliding rod 7. The bottom surface of the arc-shaped support plate 8 abuts against the side wall of the composite pipe body 1.

[0028] The protective shell 2 provides a protective layer for the composite tube 1, preventing it from being directly impacted. When the protective shell 2 is hit, the spring chamber 3 inside the protective shell 2, through the cooperation of the slider 5, the slide rod 7 and the arc-shaped support plate 8, provides a buffering effect for the impact force, preventing the impact force from hitting the composite tube 1, thus protecting the composite tube 1, preventing damage to the composite tube 1, improving the impact resistance of the composite tube 1, and having a simple structure and being easy to manufacture.

[0029] An anti-slip pad 9 is provided at the connection between the arc-shaped support plate 8 and the composite pipe body 1.

[0030] Among them, by setting anti-slip pad 9, the anti-slip properties of anti-slip pad 9 enable slide rod 7 to better clamp composite tube 1.

[0031] The bottom surface of the anti-slip mat 9 has multiple strip grooves 10.

[0032] By setting multiple strip grooves 10, the strip grooves 10 will provide roughness to the contact surface between the anti-slip pad 9 and the composite tube 1, thereby enhancing the friction and providing stability for the anti-slip pad 9 to hold the composite tube 1.

[0033] Multiple cushioning cotton 11 is provided on one side of the arc-shaped support plate 8.

[0034] The system incorporates a buffer cotton 11, which fills the remaining space on both sides of the arc-shaped support plate 8. This buffer cotton provides cushioning force when the composite tube 1 is displaced due to impact, thus better protecting the composite tube 1. The buffer cotton contains numerous micropores or fiber structures; when subjected to external impact, these structures deform, absorbing and dispersing impact energy, effectively reducing damage to the protected object. After being compressed, the buffer cotton quickly returns to its original shape, maintaining the stability of its cushioning performance. This allows it to continue to provide good cushioning even after multiple impacts.

[0035] The outer side of the protective shell 2 is covered with a buffer layer 12.

[0036] The buffer layer 12, formed on the outside of the protective shell 2, further reduces the impact force generated by collisions. Besides possessing the elasticity of rubber, it also exhibits excellent oil resistance. In the buffer devices of mechanical equipment, if the working environment contains oil, the nitrile rubber buffer layer can be used for a long time without being corroded by oil, ensuring that the buffering performance is not affected. Simultaneously, it also has good heat resistance and airtightness, making it suitable for applications requiring sealing and heat resistance.

[0037] The protective shell 2 has multiple positioning holes 13 at one end, and symmetrical positioning pins 14 are fixedly connected to the other end of the protective shell 2.

[0038] By using the positioning hole 13 and the positioning pin 14, when installing the composite tube 1, the positioning pin 14 on one side of the protective shell 2 above the adjacent composite tube 1 can be slid into the symmetrical positioning hole 13 of the other protective shell 2, so that the two protective shells 2 can be assembled, improving the convenience of installation.

[0039] One end of the positioning pin 14 is fixedly connected to a tapered guide head 15.

[0040] The tapered guide head 15 provides a certain guiding effect for the positioning pin 14 to slide into the positioning hole 13, which facilitates the connection of the pipeline.

[0041] Working Principle: When using this impact-resistant steel-lined polyurethane composite pipe, a protective shell 2 provides a protective layer for the composite pipe body 1. A buffer layer 12, forming a protective layer outside the protective shell 2, further reduces the impact force. Besides possessing the elasticity of rubber, it also exhibits excellent oil resistance. In the buffer devices of mechanical equipment, if the working environment contains oil, the nitrile rubber buffer layer can be used for a long time without being corroded by oil, ensuring that the buffering performance is not affected. Simultaneously, it also has good heat resistance and airtightness, making it suitable for applications requiring sealing and heat resistance.

[0042] The cushioning cotton contains numerous tiny pores or fiber structures. When subjected to external impact, these structures deform, absorbing and dispersing the impact energy, thus effectively reducing damage to the protected object. After being compressed, the cushioning cotton quickly returns to its original shape, maintaining the stability of its cushioning performance. This allows it to continue to provide good cushioning even after multiple impacts. It prevents the composite tube 1 from being directly struck, and when the protective shell 2 is impacted, the spring chamber 3 inside the protective shell 2, through the cooperation of the slider 5, the sliding rod 7, and the arc-shaped support plate 8, provides cushioning for the impact force, preventing this force from impacting the composite tube 1, thereby protecting the composite tube 1, preventing damage to the composite tube 1, improving the impact resistance of the composite tube 1, and having a simple structure that is easy to manufacture.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
