Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, and more specifically, it relates to a reinforced steel pipe that is resistant to deformation. Background Technology

[0002] Steel pipes are steel materials with hollow cross-sections, whose length is much greater than their diameter or circumference. They are classified by cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; by application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and by manufacturing process into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, while welded steel pipes are divided into straight-seam welded steel pipes and spiral-seam welded steel pipes.

[0003] During transportation or loading and unloading, the ends of steel pipes are directly exposed to external impacts (such as hoisting collisions, vehicle bumps, or stacking and squeezing). Since the ends of steel pipes are free ends and lack radial restraint, their impact resistance is significantly lower than that of the pipe body (especially for thin-walled steel pipes, which are more sensitive when the wall thickness δ≤8mm). The ends of steel pipes are prone to local plastic deformation, resulting in deviations in the roundness of the ends (such as excessive ellipticity or edge depressions). Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reinforced steel pipe that is resistant to deformation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A deformation-resistant reinforced steel pipe includes a steel pipe body. Reinforcement modules are provided at both ends of the steel pipe body. Each reinforcement module includes a central positioning seat and several protective parts surrounding the central positioning seat. The central positioning seat is in the shape of a regular polygonal prism. The number of protective parts is equal to the number of sides of the central positioning seat. The protective parts are movably connected to multiple sides of the central positioning seat. Each protective part includes an outer protective plate and an inner reinforcing plate corresponding to the outer protective plate. The outer protective plate contacts the outer surface of the steel pipe body, and the inner reinforcing plate contacts the inner surface of the steel pipe body. The protective parts are located at one end of the central positioning seat. A support rod is movably connected to each side of the other end of the central positioning seat, and the support rod abuts against the inner reinforcing plate.

[0007] Further configured, the protective part also includes a guide block, on which a first threaded groove and a second threaded groove are formed. A first movable rod is threadedly connected to the first threaded groove, and the output end of the first movable rod is rotatably connected to the outer protective plate. A second movable rod is threadedly connected to the second threaded groove, and the output end of the second movable rod abuts against one end of the inner reinforcing plate. The output end of the support rod is movably connected to the other end of the inner reinforcing plate.

[0008] A further configuration is provided, wherein each side of the other end of the central positioning seat is provided with a third threaded groove that mates with the corresponding support rod, and one end of the support rod is threadedly connected to the third threaded groove.

[0009] A further configuration is provided, wherein an elastic block corresponding to the other end of the support rod is fixed to the other end of the inner reinforcing plate, an mounting block is fixed to the elastic block, a bearing is fixed to the mounting block, and the other end of the support rod is rotatably connected to the mounting block through the bearing on the mounting block.

[0010] Further configured, the inner reinforcing plate includes an inclined surface, which corresponds to and abuts against the inner surface of the steel pipe body.

[0011] A further configuration is provided, wherein a positioning groove corresponding to the second movable rod is formed on the inclined surface, and the output end of the second movable rod moves within the positioning groove and abuts against the inner wall of the bottom of the positioning groove.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: during the transportation or loading and unloading of the steel pipe, the reinforcement module reinforces the end of the steel pipe, thereby enhancing the impact resistance of the end of the steel pipe and avoiding the problem that the end of the steel pipe is easily deformed due to direct exposure to external impact, resulting in reduced roundness and edge depression.

Detailed Implementation

[0016] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0017] A deformation-resistant reinforced steel pipe includes a steel pipe body 1. Reinforcement modules 100 are provided at both ends of the steel pipe body 1. Each reinforcement module 100 includes a central positioning seat 2 and several protective parts arranged around the central positioning seat 2. The central positioning seat 2 is in the shape of a regular polygonal prism. The number of protective parts is equal to the number of sides of the central positioning seat 2. The several protective parts are movably connected to multiple sides of the central positioning seat 2. Each protective part includes an outer protective plate 3 and an inner reinforcing plate 4 corresponding to the outer protective plate 3. The outer protective plate 3 contacts the outer surface of the steel pipe body 1, and the inner reinforcing plate 4 contacts the inner surface of the steel pipe body 1. The several protective parts are placed at one end of the central positioning seat 2. Each side of the other end of the central positioning seat 2 is movably connected to a support rod 5, which abuts against the inner reinforcing plate 4.

[0018] The protective section also includes a guide block 6, which has a first threaded groove 61 and a second threaded groove 62. A first movable rod is threadedly connected to the first threaded groove 61, and the output end of the first movable rod is rotatably connected to the outer protective plate 3 via a bearing. A second movable rod is threadedly connected to the second threaded groove 62, and the output end of the second movable rod mates with one end of the inner reinforcing plate 4. The inner reinforcing plate 4 includes an inclined surface 12, which corresponds to and abuts against the inner surface of the steel pipe body 1. A positioning groove 13 corresponding to the second movable rod is formed on the inclined surface 12, and the output end of the second movable rod mates with the positioning groove 13. The support rod 5 is movably connected to and abuts against the bottom inner wall of the positioning groove 13. The output end of the support rod 5 is movably connected to the other end of the inner reinforcing plate 4. Each side of the other end of the center positioning seat 2 has a third threaded groove 9 that mates with the corresponding support rod 5. One end of the support rod 5 is threadedly connected to the third threaded groove 9. The other end of the inner reinforcing plate 4 is fixed with an elastic block 10 corresponding to the other end of the support rod 5. An installation block 11 is fixed on the elastic block 10. A bearing is fixed on the installation block 11. The other end of the support rod 5 is rotatably connected to the installation block 11 through the bearing on the installation block 11.

[0019] Working Principle: The central positioning seat 2 is a regular polygonal prism, with the number of its sides equal to the number of protective parts. This ensures that the protective parts are evenly distributed around the steel pipe end, forming a stable reinforcement structure that allows the steel pipe end to be evenly stressed in all directions. Through the dual protection of the outer protective plate 3 and the inner reinforcing plate 4, the reinforcement module 100 effectively prevents localized deformation of the steel pipe end due to external impacts. The outer protective plate 3 blocks external impacts, while the inner reinforcing plate 4 provides internal support. The elastic block 10 and the support rod 5 further absorb and disperse the impact force, thereby ensuring the roundness and integrity of the steel pipe end.

[0020] In use, the distance between the outer protective plate 3 and the inner protective plate is adjusted according to the wall thickness of the steel pipe body 1, so that the outer protective plate 3 contacts the outer surface of the steel pipe body 1, thereby protecting the outer wall of the steel pipe; the inner reinforcing plate 4 contacts the inner surface of the steel pipe body 1, and cooperates with the second and third movable rods to support the inner reinforcing plate 4, thereby reinforcing the inner wall of the steel pipe. The first screw groove 61 and the second screw groove 62 on the guide block 6 are threaded with the first movable rod and the second movable rod respectively, thereby realizing the flexible adjustment and fixation of the distance between the outer protective plate 3 and the inner protective plate.

[0021] The first movable rod is threadedly connected to the first screw groove 61 of the guide block 6, and its output end is rotatably connected to the outer protective plate 3. By rotating the first movable rod, the position of the outer protective plate 3 can be adjusted so that it fits tightly against the outer surface of the steel pipe body 1, thereby providing external protection and preventing external impacts from directly acting on the outer wall of the steel pipe.

[0022] The inner reinforcing plate 4 is connected to the second screw groove 62 of the guide block 6 via the second movable rod. By rotating the first movable rod, the inclined surface 12 of the inner reinforcing plate 4 is made to fit tightly against the inner surface of the steel pipe body 1. This structural design allows the inner reinforcing plate 4 to be finely adjusted according to the shape of the inner surface of the steel pipe, ensuring that it is in close contact with the inner wall of the steel pipe, thereby providing internal support and enhancing the impact resistance of the steel pipe. The positioning groove 13 facilitates the precise contact point between the first movable rod and the inner reinforcing plate 4, allowing the first movable rod to better support the inner reinforcing plate 4.

[0023] The elastic block 10 fixed to the other end of the inner reinforcing plate 4 allows for angular adjustment at the connection between the other end of the inner reinforcing plate 4 and the supporting rod 5 when the second movable rod rotates and lifts the inclined surface 12 of the inner reinforcing plate 4 to fit tightly against the outer surface of the steel pipe body 1. This allows the second movable rod to smoothly lift the inner reinforcing plate 4 so that its inclined surface 12 fits tightly against the outer surface of the steel pipe body 1. A bearing is installed on the elastic block 10, and the output end of the supporting rod 5 is rotatably connected to the mounting block 11 via the bearing, facilitating the smooth rotation of the supporting rod 5 within the third screw groove 9 to support the inner reinforcing plate 4.

[0024] During transportation or loading / unloading, steel pipes may be subjected to external impacts. The outer protective plate 3, adjusted by the first movable rod, fits tightly against the outer surface of the steel pipe, effectively blocking external impacts and preventing direct impact force on the pipe ends. Even if impact force is transmitted to the outer protective plate 3, it will be dispersed by the guide block 6 and the central positioning seat 2, avoiding localized stress concentration that could lead to deformation. The inner reinforcing plate 4 fits tightly against the inner surface of the steel pipe via the inclined surface 12 and is fixed by the second movable rod and the support rod 5, providing internal support and enhancing the rigidity of the steel pipe ends. When external impact force is transmitted to the inner wall of the steel pipe, the inner reinforcing plate 4 disperses the impact force, preventing localized deformation of the inner wall. Ultimately, during transportation or loading / unloading, the reinforcing module 100 reinforces the steel pipe ends, thereby strengthening the impact resistance of the steel pipe ends and preventing localized deformation of the pipe ends due to direct exposure to external impacts, which could lead to reduced roundness and edge concavity.
