Description

Technical Field

[0001] The utility model relates to the field of fiberglass reinforced plastic (FRP) conveying pipelines, and particularly to a continuously pultruded FRP high-pressure conveying pipeline. Background Art

[0002] The FRP pipeline is a non-metallic pipeline with light weight, high strength and corrosion resistance. Glass fibers with a resin matrix are wound layer by layer on a rotating core mold according to process requirements, and quartz sand is evenly laid between the fibers at a long distance as a sand sandwich layer. Its pipe wall structure is reasonable and advanced, which can give full play to the role of materials. Under the premise of meeting the use strength, the rigidity is improved, and the stability and reliability of the product are ensured. Its excellent chemical corrosion resistance, light weight and high strength, no scaling, strong seismic resistance, longer service life compared with ordinary steel pipes, low comprehensive cost, quick installation, safety and reliability and other advantages are accepted by the majority of users.

[0003] However, when the existing FRP high-pressure conveying pipeline is hoisted and moved, the FRP high-pressure conveying pipeline is prone to side slip from the upper side of the lifting rope, thus falling from a high place, which is likely to cause safety accidents. This not only reduces the stability of the FRP high-pressure conveying pipeline during hoisting, but also reduces the moving efficiency of the FRP high-pressure conveying pipeline during hoisting. Therefore, it is very necessary to propose a continuously pultruded FRP high-pressure conveying pipeline to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a continuously pultruded FRP high-pressure conveying pipeline to solve the problems that when the existing FRP high-pressure conveying pipeline is hoisted and moved, the FRP high-pressure conveying pipeline is prone to side slip from the upper side of the lifting rope, thus falling from a high place, which is likely to cause safety accidents, not only reducing the stability of the FRP high-pressure conveying pipeline during hoisting, but also reducing the moving efficiency of the FRP high-pressure conveying pipeline during hoisting.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a continuously pultruded FRP high-pressure conveying pipeline, including a pipeline body, a reinforcing pipe is fixedly arranged on the outer circle of the pipeline body, and an anti-slip component is arranged on the outer circle of the reinforcing pipe;

[0006] The anti-slip component includes two limiting rings fixedly arranged on the outer circle of the reinforcing pipe. The two limiting rings are symmetrically arranged about the central line of the reinforcing pipe. Each limiting ring includes two symmetrically arranged baffles. Rubber plates are fixedly arranged on the mutually approaching surfaces of the two baffles. The rubber plates are in a semi-circular arc structure, and a lifting rope is placed between the two rubber plates;

[0007] The reinforcing pipe includes a cement sleeve and a steel bar component located inside the cement sleeve.

[0008] Preferably, a corrosion-resistant layer is fixedly arranged on the inner circle of the pipeline body.

[0009] Preferably, a placement box is fixedly arranged between the two groups of limiting rings. A protection plate is fixedly arranged on the top of the placement box. The protection plate is in an arc-shaped structure. The interior of the placement box is filled with red powder.

[0010] Preferably, the steel bar assembly includes bottom bars which are fixedly arranged on the outer ring of the pipeline body and are evenly distributed in a ring shape. A plurality of uniformly distributed extended bars are fixedly arranged on the side of the bottom bar away from the pipeline body. A reinforcing bar is fixedly arranged at one end of the extended bar away from the bottom bar. A top bar is also fixedly arranged at one end of the extended bar away from the bottom bar. The top bar and the reinforcing bar are fixedly connected.

[0011] Preferably, there is a gap between the corresponding two rubber plates, and the surfaces of the rubber plates close to each other are in a toothed structure.

[0012] Preferably, the baffle and the cement casing are integrally formed.

[0013] Preferably, the central axis of the reinforcing bar and the central axis of the pipeline body are on the same straight line. The diameter of the reinforcing bar is larger than the diameter of the pipeline body, and the diameter of the reinforcing bar is smaller than the diameter of the cement casing.

[0014] The technical effects and advantages of the present utility model are as follows:

[0015] 1. By installing the anti-slip assembly, the lifting rope is wound around the lower surface of the pipeline body and limited between the two baffles. Thus, when lifting the pipeline body, it can be avoided that the pipeline body slides off the upper side of the lifting rope, solving the problem that in the existing pipeline body during hoisting and moving, the pipeline body is prone to sliding off the upper side of the lifting rope, thus falling from a high place, which is likely to cause safety accidents, not only reducing the stability of the pipeline body during hoisting, but also reducing the moving efficiency of the pipeline body during hoisting.

[0016] 2. By installing the rubber plates, the friction between the two baffles and the lifting rope is increased, thus avoiding the pipeline body from rolling on the lifting rope and improving the stability of lifting the pipeline body.

[0017] 3. By arranging the reinforcing pipe, the compressive strength of the pipeline body is enhanced, the safety performance of the pipeline body is improved, and it is applicable to transporting high-pressure fluids.

[0018] 4. By fixedly connecting the bottom bars, extended bars, reinforcing bars and top bars through welding or binding, etc., a stable steel reinforcement cage is jointly formed, and then concrete is poured into it to form a cement casing, enhancing the strength and toughness of the cement casing while strengthening the compressive strength of the pipeline body.

[0019] 5. During construction, if an excavator accidentally touches the pipe body, the installation of the protective plate provides primary protection for the pipe body. In addition, when the protective plate is damaged, the red powder inside the placement box will overflow, notifying the construction workers that the protective plate has been touched, thus preventing further excavation and damage to the pipe body.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides a continuous pultruded fiberglass high-pressure transmission pipe as Figures 1 - 5 shown, including a pipe body 1. A reinforcing pipe is fixedly arranged on the outer circle of the pipe body 1. Through the arrangement of the reinforcing pipe, the compressive strength of the pipe body 1 is enhanced, and the safety performance of the pipe body 1 is improved, making it suitable for transporting high-pressure fluids.

[0028] Considering that when the existing pipe body 1 is hoisted and moved, the pipe body 1 is prone to slipping from the upper side of the lifting rope and thus falling from a height, which is likely to cause safety accidents, not only reducing the stability of the pipe body 1 during hoisting but also reducing the moving efficiency of the pipe body 1 during hoisting. Therefore, the present utility model is provided with an anti-slip component on the outer circle of the reinforcing pipe.

[0029] Furthermore, the anti-slip assembly includes two groups of limiting rings fixedly arranged on the outer circle of the reinforcing pipe. The two groups of limiting rings are symmetrically arranged with respect to the central line of the reinforcing pipe. Each group of limiting rings includes two symmetrically arranged baffles 4. Rubber plates 5 are fixedly arranged on the mutually approaching surfaces of the two baffles 4. The rubber plates 5 are in a semi-circular arc structure. There is a gap between the two rubber plates 5, and a lifting rope is placed between the two rubber plates 5.

[0030] Specifically, the lifting rope is wound around the lower surface of the pipe body 1 and limited between the two baffles 4. Thus, when lifting the pipe body 1, it is possible to prevent the pipe body 1 from slipping from the upper side of the lifting rope, solving the problem that in the existing lifting and moving of the pipe body 1, the pipe body 1 is prone to slipping from the upper side of the lifting rope, thus falling from a height, which is likely to cause safety accidents, not only reducing the stability of the pipe body 1 during lifting, but also reducing the moving efficiency of the pipe body 1 during lifting.

[0031] In addition, in order to further prevent the pipe body 1 from rolling on the lifting rope, through the installation of the rubber plates 5, the friction between the two baffles 4 and the lifting rope is increased, thereby preventing the pipe body 1 from rolling on the lifting rope and improving the stability of lifting the pipe body 1.

[0032] Furthermore, the mutually approaching surfaces of the rubber plates 5 are in a toothed structure. With such a setting, the biting force between the rubber plates 5 and the lifting rope is increased, and the stability of lifting the pipe body 1 is improved.

[0033] Furthermore, the reinforcing pipe includes a cement casing 2 and a steel bar assembly located inside the cement casing 2. With the assistance of the steel bar assembly, the strength and toughness of the cement casing 2 are improved.

[0034] Specifically, the steel bar assembly includes bottom bars 8. The bottom bars 8 are fixedly arranged on the outer circle of the pipe body 1 and are evenly distributed in a ring shape. A number of uniformly distributed extended bars 9 are fixedly arranged on the surface of the bottom bars 8 away from the pipe body 1. A reinforcing bar 10 is fixedly arranged at one end of the extended bar 9 away from the bottom bar 8. A top bar 11 is also fixedly arranged at one end of the extended bar 9 away from the bottom bar 8. The top bar 11 and the reinforcing bar 10 are fixedly connected. The bottom bars 8, extended bars 9, reinforcing bars 10, and top bars 11 are fixedly connected by welding or tying, etc., to jointly form a stable steel bar cage, and then concrete is poured into it to form the cement casing 2, improving the performance of the cement casing 2 and enhancing the compressive strength of the pipe body 1 at the same time.

[0035] Considering that in the fields of oil fields, brine, and chemical industries, the pipeline body 1 will be severely corroded over time. After being corroded by media such as acids and alkalis, the inner wall of the pipeline is extremely likely to become rough, or the pipeline will perforate and leak, seriously affecting industrial production or causing environmental pollution. Therefore, a corrosion-resistant layer 3 is fixedly arranged at the inner circle of the pipeline body 1. Through the protection of the corrosion-resistant layer 3, the service life of the pipeline body 1 is extended.

[0036] Since the pipeline body 1 is generally buried underground, during construction, excavators often accidentally touch the long pipeline body 1, resulting in damage to the long pipeline body 1. Therefore, a placement box 6 is fixedly arranged between two groups of limiting rings. A protection plate 7 is fixedly arranged at the top of the placement box 6. The protection plate 7 is in an arc-shaped structure. The interior of the placement box 6 is filled with red powder. Through the protection plate 7, the pipeline body 1 is protected for the first time. In addition, after the protection plate 7 is damaged, the red powder inside the placement box 6 will overflow, informing the construction personnel that they have touched the protection plate 7, thereby avoiding further excavation and damaging the pipeline body 1.

[0037] Furthermore, the baffle 4 and the cement casing 2 are integrally formed, which improves the installation stability of the baffle 4.

[0038] Furthermore, the central axis of the reinforcing rib 10 and the central axis of the pipeline body 1 are on the same straight line. The diameter of the reinforcing rib 10 is larger than the diameter of the pipeline body 1, and the diameter of the reinforcing rib 10 is smaller than the diameter of the cement casing 2. This enables the steel bar assembly to be evenly located inside the cement casing 2, avoiding exposure and corrosion by air.
