Description

TECHNICAL FIELD

[0001] The utility model belongs to seamless pipe technical field, concretely relates to a kind of bending-resistant seamless pipe. BACKGROUND

[0002] Seamless pipe is a kind of circular, square, rectangular or other shape steel pipe with hollow section and no joint on periphery. The production process of seamless pipe mainly has hot rolling and cold drawing two kinds, which is manufactured through perforating, rolling, drawing and other processes. Since there is no welding joint, seamless pipe is more complete in structure, has a series of unique advantages, so it is widely used in many industrial fields.

[0003] In the application No. 202420570180.6 discloses a kind of bending-resistant seamless pipe, "first, strengthen cover A and strengthen cover B are placed to the outside of seamless pipe main body, then rotate the screw sleeve A outside strengthen cover A, then screw sleeve A moves to the outside of support plate A through thread groove A, support plate A outside strengthen cover A is provided with four groups, support plate A is fixed on the outside of seamless pipe main body, then rotate the screw sleeve B outside strengthen cover B, support plate B outside strengthen cover B is provided with four groups, then screw sleeve B moves to the outside of support plate B through thread groove B, so that support plate B and the surface of seamless pipe main body are in close contact, so that the reinforcing rod A on strengthen cover A and the reinforcing rod B on strengthen cover B are fixed on the outside of seamless pipe main body, reinforcing rod A and strengthening cover B are provided with two groups, to improve the bending resistance of seamless pipe main body", the above-mentioned is clamped and fixed to the seamless pipe main body by strengthen cover A and strengthen cover B, which can effectively ensure the stability and bending resistance of seamless pipe under various working conditions. But in actual use, seamless pipe often needs to bear the continuous pressure and sudden impact force from the outside world in actual application. Taking natural gas transportation as an example, as a key conveying pipeline, seamless pipe not only has to bear the high pressure of internal conveying medium, but also has to cope with complex external environmental challenges. When the manhole cover is damaged or accidentally damaged, heavy objects may fall and directly hit the pipeline. In the protection structure of seamless pipe, strengthen cover A and strengthen cover B play an important role. However, when they are subjected to external impact or external force, these external components are prone to damage. Once the strengthen cover is damaged, its own structural strength will be reduced, which directly leads to poor clamping effect, and further shortens the service life of the clamping piece. Since the clamping piece is a key component to ensure the stability of the seamless pipe, once its performance declines or fails, it will have many adverse effects on the seamless pipe, which may cause displacement, deformation of the seamless pipe, and even rupture in extreme cases. This not only shortens the service life of the seamless pipe, but also may cause safety hazards, posing a serious threat to the reliability and safety of the entire system. SUMMARY

[0004] The utility model discloses a purpose at providing a kind of anti-bending seamless tube, to solve the reinforcing sleeve A and B clamping fixed seamless tube main body in the background technique proposed above, ensure its stability, but vulnerable to impact damage, lead to clamping effect is poor, affect the life of seamless tube, even cause fracture and security hidden trouble problem.

[0005] To achieve the above object, the utility model provides the following technical scheme: an anti-bending seamless tube, comprising: a seamless tube body, the outer wall of the seamless tube body is respectively provided with clamping A component and clamping B component at both ends, first clamping plate and second clamping plate are arranged in the clamping A component and the clamping B component, first connecting plate is arranged at both ends of the first clamping plate, second connecting plate is arranged at both ends of the second clamping plate, first fastening bolt is connected between adjacent two first connecting plates and second connecting plates, a plurality of mounting blocks are arranged on the outer wall of the first clamping plate and the second clamping plate, anti-collision block is sleeved on the mounting block, a plurality of first springs are connected between the mounting block and the anti-collision block.

[0006] Preferably, the first clamping plate and the second clamping plate are both semicircular rings, the mounting block is a semisolid sphere, and the anti-collision block is a semihollow sphere.

[0007] Through the above technical scheme:

[0008] When in use, the anti-bending seamless tube takes the seamless tube body as the core, and the seamless tube body is located at the center position of the whole structure and serves as the installation basis of all other components. At both ends of the outer wall of the seamless tube body, clamping A component and clamping B component are respectively assembled, and the two components are symmetrically distributed at both ends of the seamless tube, which can ensure uniform stress of the whole.

[0009] Each clamping component includes first clamping plate and second clamping plate, and both clamping plates are designed in a semicircular ring shape. When they are combined together, a complete ring is formed, which can tightly clamp the seamless tube body and ensure that the seamless tube remains stable under various working conditions. First connecting plate is arranged at both ends of the first clamping plate, and second connecting plate is arranged at both ends of the second clamping plate. The first connecting plate and the second connecting plate are connected by the first fastening bolt, which not only enhances the stability of the clamping plate but also ensures uniform distribution of clamping force, effectively preventing deformation or displacement of the seamless tube during stress process.

[0010] To further improve the impact resistance, the mounting blocks are ingeniously installed on the outer walls of the first and second clamping plates. The mounting blocks are semi-solid spheres, and the outer part is equipped with anti-collision blocks, which are semi-hollow spheres. The semi-solid mounting blocks can evenly disperse the impact force from any direction to a larger contact area due to their unique spherical structure, effectively preventing local stress concentration and reducing the risk of damage to the first and second clamping plates. The semi-hollow anti-collision blocks can further absorb and disperse the impact force by elastic deformation when impacted. The hollow part allows the anti-collision block to deform when impacted, thereby absorbing more energy.

[0011] In addition, the first spring connects the mounting block and the anti-collision block, providing additional cushioning and shock absorption functions. When the first and second clamping plates are impacted from the outside, the first spring can absorb part of the energy, further enhancing the impact resistance of the overall structure. This design not only protects the clamping assembly itself, but also indirectly protects the internal seamless pipe body, allowing it to maintain good performance in harsh environments.

[0012] The clamping assembly (clamping A assembly and clamping B assembly) provides a stable clamping force for the seamless pipe body through the combination of the first and second clamping plates.

[0013] The connecting plates (first and second connecting plates) and fastening bolts (first fastening bolts) ensure the stability of the clamping plates and the uniform distribution of clamping force, allowing the seamless pipe to maintain a stable state during use.

[0014] The combination of mounting blocks, anti-collision blocks and first springs forms an efficient buffer system that can effectively absorb and disperse external impact forces, preventing damage to the clamping assembly and the seamless pipe body.

[0015] This design enhances the anti-collision ability of the clamping assembly, making it less likely to be damaged, thereby protecting the internal seamless pipe body and extending its service life.

[0016] By optimizing the clamping and anti-collision structure, this anti-bending seamless pipe not only improves the bending resistance, but also enhances the overall durability and safety.

[0017] This design can effectively protect the seamless pipe during transportation, installation and use, ensuring its reliability and stability in various complex environments.

[0018] In summary, the structural design of the anti-bending seamless pipe achieves stable clamping and effective collision prevention through the synergy of multiple components. The optimized clamping and collision prevention system not only improves the anti-bending performance of the seamless pipe but also enhances its durability and safety, enabling it to perform excellently in various application scenarios. This design concept fully considers various demands and challenges in actual use, providing reliable protection for the application of seamless pipes.

[0020] Preferably, the clamping assembly comprises a clamping groove and a clamping block, the clamping groove is opened in the outer wall of the first connecting plate and the second connecting plate, and the clamping block is connected to the side wall of the movable column, and the clamping groove and the clamping block are matched.

[0021] Through the above technical solutions:

[0022] In use, after the preliminary installation of the first connecting plate and the second connecting plate is completed, the two are firmly connected by means of the first fastening bolt. At this time, the mounting plate is precisely placed on the side walls of the first connecting plate and the second connecting plate. To achieve further fixation and adjustment, the operator can push the mounting plate to make the clamping block slide along the outer wall of the first connecting plate and the second connecting plate. When the clamping block moves to the predetermined position, it will be accurately embedded in the clamping groove. At the same time, the movable column moves correspondingly inside the hollow cylinder, and the second spring ensures that the clamping block is firmly locked in the clamping groove by its own elastic force. This design not only realizes quick and accurate fixation, but also significantly enhances the connection strength between the first connecting plate and the second connecting plate by using the mounting plate as a connecting bridge.

[0023] Thanks to the connecting effect of the mounting plate, the combination of the first connecting plate and the second connecting plate is more firm, and it is not easy to loosen or fall off, which ensures the stability of the overall structure, especially when bearing a large load or external impact, the connection performance is still good.

[0024] The matching design of the clamping block and the clamping groove makes the fixing process simple and efficient. The operator only needs to push the mounting plate to complete the positioning and locking of the clamping block, which reduces the complexity of manual operation and improves the installation efficiency.

[0025] The elastic force of the second spring provides continuous fastening force for the clamping block, ensuring that it can maintain a stable locked state under various working conditions. Even if subjected to external vibration or impact, the second spring can effectively absorb energy to prevent the clamping block from falling out of the clamping groove.

[0026] The combination of the mounting plate, the clamping block, and the clamping slot constitutes a modular connection system. This design not only enhances the flexibility of the structure but also facilitates later maintenance and repair. When it is necessary to disassemble or replace components, the operator can easily separate the clamping block and the clamping slot to achieve quick disassembly.

[0027] This design can meet the connection needs of seamless pipes of different specifications and shapes. By adjusting the position of the mounting plate and the locking state of the clamping block, precise clamping and fixing of seamless pipes of different diameters and lengths can be achieved.

[0028] In summary, through the coordinated operation of the mounting plate, the clamping block, the clamping slot, and the second spring, this structure realizes the stable fixation and convenient adjustment of the seamless pipe connection assembly. This design not only enhances the connection strength of the connection plate but also improves the stability and reliability of the overall structure.

[0030] Preferably, the protection assembly comprises a hollow rod, a movable rod, and a protective sleeve, the hollow rod is connected to the clamping A assembly, the movable rod is connected to the clamping B assembly, and the protective sleeve is sleeved on the outer wall of the hollow rod.

[0031] Through the above technical solutions:

[0032] In use, the first limiting plate is stably connected to the clamping A assembly, which mainly functions as a limiting device for the clamping A assembly, accurately limiting its movement range and effectively preventing excessive displacement during the stress process. At the same time, the first limiting plate also provides a crucial mounting point for connecting the second fastening bolt and the second limiting plate, thereby enhancing the stability and firmness of the overall structure.

[0033] The second limiting plate is connected to the clamping B assembly, also serving as a limiting device for the clamping B assembly, limiting its movement range and ensuring the stability and reliability of the clamping B assembly under various working conditions. The outer wall of the second limiting plate is uniformly distributed with a plurality of through grooves, which not only reduce the weight of the structure but also facilitate flexible adjustment of the spacing between the clamping A assembly and the clamping B assembly. In addition, the second limiting plate also provides a mounting point for connecting the second fastening bolt and the first limiting plate, ensuring the stable and reliable connection between the two.

[0034] The second fastening bolt plays a key connecting role between the first limiting plate and the second limiting plate. By tightening the bolt, the first limiting plate and the second limiting plate are tightly fixed, providing the necessary fastening force to prevent the limiting plates from loosening or shifting when subjected to external forces, which significantly improves the stability and impact resistance of the overall structure.

[0035] During the installation of the clamping A assembly and the clamping B assembly, the movable rod can move flexibly inside the hollow rod to meet different clamping needs and displacement conditions. The protective sleeve is tightly sleeved on the outer wall of the hollow rod, providing an additional protective layer to prevent external objects from damaging the hollow rod and the movable rod.

[0036] The cooperative operation of the movable rod and the hollow rod enhances the connectivity between the clamping A assembly and the clamping B assembly, making the seamless pipe body less prone to bending when subjected to external forces. This design ensures the stability and safety of the seamless pipe during use. The presence of the protective sleeve further improves the durability of the overall structure, as it not only protects the hollow rod and the movable rod but also absorbs part of the energy when impacted, acting as a buffer.

[0037] The first limiting plate and the second limiting plate are connected by the second fastening bolt, achieving precise limiting and stable connection of the clamping assembly, effectively preventing excessive displacement and loosening.

[0038] The design of the through slot allows the spacing between the clamping A assembly and the clamping B assembly to be flexibly adjusted to accommodate seamless pipes of different sizes, enhancing the adaptability of the structure.

[0039] The combination of the movable rod and the hollow rod ensures firm connection and flexible movement between the clamping assemblies. The protective sleeve provides an additional protective layer to prevent damage to key components by external objects and plays a buffering role when impacted.

[0040] Through multiple protection mechanisms and stable connection design, the overall structure can maintain good performance in various complex environments, prolonging the service life of the seamless pipe and improving safety.

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0054] Please refer to Figures 1-6 As shown in the figure, the utility model provides the following technical scheme: a bending-resistant seamless pipe, comprising: a seamless pipe body 1, a clamping A assembly and a clamping B assembly are respectively installed at the two ends of the outer wall of the seamless pipe body 1, a first clamping plate 2 and a second clamping plate 3 are arranged in the clamping A assembly and the clamping B assembly, a first connecting plate 4 is installed at the two ends of the first clamping plate 2, a second connecting plate 5 is installed at the two ends of the second clamping plate 3, a first fastening bolt 6 is connected between adjacent two first connecting plates 4 and second connecting plates 5, a plurality of mounting blocks 7 are installed on the outer wall of the first clamping plate 2 and the second clamping plate 3, an anti-collision block 8 is sleeved on the mounting block 7, and a plurality of first springs 9 are connected between the mounting block 7 and the anti-collision block 8.

[0056] Through the above technical scheme:

[0057] When used, the bending-resistant seamless pipe takes the seamless pipe body 1 as the core, the seamless pipe body 1 is located at the center position of the whole structure and is the installation basis of all other assemblies. At the two ends of the outer wall of the seamless pipe body 1, the clamping A assembly and the clamping B assembly are respectively assembled, and the two assemblies are symmetrically distributed at the two ends of the seamless pipe, which can ensure that the overall stress is uniform.

The mounting blocks 7 are semi-solid spheres, and the outer part is equipped with anti-collision blocks 8, which are semi-hollow spheres. The semi-solid spherical mounting blocks 7, due to their unique spherical structure, can evenly distribute impact force from any direction to a larger contact area, effectively preventing local stress concentration and reducing the risk of damage to the first clamp plate 2 and the second clamp plate 3. The semi-hollow spherical anti-collision blocks 8 can elastically deform when impacted, further absorbing and dispersing impact force. The hollow part allows the anti-collision blocks 8 to deform when impacted, thereby absorbing more energy.

[0060] In addition, the first spring 9 connects the mounting block 7 and the anti-collision block 8, providing additional cushioning and shock absorption functions. When the first clamp plate 2 and the second clamp plate 3 are impacted from the outside, the first spring 9 can absorb part of the energy, further enhancing the impact resistance of the overall structure. This design not only protects the clamping assembly itself but also indirectly protects the internal seamless pipe body 1, allowing it to maintain good performance in harsh environments.

[0061] The clamping assembly (clamping A assembly and clamping B assembly) provides a stable clamping force for the seamless pipe body 1 through the combination of the first clamp plate 2 and the second clamp plate 3.

[0062] The connecting plates (first connecting plates 4 and second connecting plates 5) and fastening bolts (first fastening bolts 6) ensure the stability of the clamp plates and the uniform distribution of clamping force, allowing the seamless pipe to maintain a stable state during use.

[0063] The combination of mounting blocks 7, anti-collision blocks 8, and first springs 9 forms an efficient buffer system that can effectively absorb and disperse external impact force, preventing damage to the clamping assembly and the seamless pipe body 1.

[0064] This design enhances the impact resistance of the clamping assembly, making it less likely to be damaged, thereby protecting the internal seamless pipe body 1 and prolonging its service life.

[0065] By optimizing the clamping and anti-collision structure, the anti-bending seamless pipe not only improves the bending resistance, but also enhances the overall durability and safety.

[0066] This design effectively protects the seamless pipe during transportation, installation, and use, ensuring its reliability and stability in various complex environments.

[0067] In summary, the anti-bending seamless pipe's structural design achieves stable clamping and effective anti-collision through the synergy of multiple components. The optimized clamping and anti-collision system not only improves the bending resistance of the seamless pipe but also enhances its durability and safety, allowing it to perform excellently in various application scenarios. This design concept fully considers various demands and challenges in actual use, providing reliable protection for the application of seamless pipes.

At this time, the mounting plate 10 is precisely placed on the side wall of the first connecting plate 4 and the second connecting plate 5. To achieve further fixation and adjustment, the operator can push the mounting plate 10, so that the clamping block 15 slides along the outer wall of the first connecting plate 4 and the second connecting plate 5. When the clamping block 15 moves to the predetermined position, it will be accurately embedded in the clamping groove 14. At the same time, the movable column 12 moves correspondingly in the hollow cylinder 11, and the second spring 13 ensures that the clamping block 15 is stably locked in the clamping groove 14 by its own elastic force.

Even if subjected to external vibration or impact, the second spring 13 can effectively absorb energy to prevent the clamping block 15 from falling out of the clamping groove 14.

[0075] The combination of the mounting plate 10, the clamping block 15 and the clamping groove 14 constitutes a modular connection system. This design not only improves the flexibility of the structure, but also facilitates later maintenance and repair. When it is necessary to disassemble or replace components, the operator can easily separate the clamping block 15 and the clamping groove 14 to achieve quick disassembly.

[0076] This design can meet the connection needs of seamless pipes of different specifications and shapes. By adjusting the position of the mounting plate 10 and the locking state of the clamping block 15, precise clamping and fixing of seamless pipes of different diameters and lengths can be achieved.

[0077] In summary, through the coordinated operation of the mounting plate 10, the clamping block 15, the clamping groove 14 and the second spring 13, this structure realizes stable fixation and convenient adjustment of the seamless pipe connection assembly.
