Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, and more specifically, it relates to a pressure-resistant steel pipe with a pressure-resistant support structure. Background Technology

[0002] Steel pipe is a type of steel with open ends and a hollow cross-section, its length being much greater than its diameter or circumference. Steel pipe specifications are expressed by their external dimensions (such as outer diameter or side length) and wall thickness, and their size range is very wide, from very small capillary tubes to large-diameter pipes several meters in diameter. According to their uses, they are classified into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industries, machinery manufacturing, geological drilling, and high-pressure equipment, etc.

[0003] After steel pipes are processed at the steel mill, they need to be transported to the place of use or intermediate warehouse. In order to increase the single transport volume and reduce the number of transports, steel pipes are generally stacked for transport. After arriving at the destination, in order to save storage space, steel pipes are also stacked for storage. However, during transportation and storage, stacking can cause problems such as pressure deformation, excessive ovality, local indentation or dent (especially serious for thin-walled pipes) in the lower layer of steel pipes.

[0004] Therefore, to address the aforementioned issues, it is necessary to design a pressure-resistant steel pipe with a pressure-resistant support structure. This structure provides internal support to the steel pipe, preventing issues such as deformation under pressure, excessive ellipticity, localized indentations, or dents when the steel pipes are stacked during transportation and storage. Furthermore, the length of the pressure-resistant support structure can be adjusted to accommodate steel pipes of different lengths, making it highly adaptable and practical. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure-resistant steel pipe with a pressure-resistant support structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pressure-resistant steel pipe with a pressure-resistant support structure includes a steel pipe body. The pressure-resistant support structure is provided inside the steel pipe body and is fitted with the inner wall of the steel pipe body. The pressure-resistant support structure includes several pressure-resistant support modules and several connecting rods. The connecting rods are respectively arranged between every two adjacent pressure-resistant support modules. Each pressure-resistant support module includes a connecting plate and several support plates evenly arranged around the connecting plate. One end of the connecting rod is fixedly connected to the connecting plate, and the other end of the connecting rod is detachably connected to the connecting plate of the adjacent pressure-resistant support module. One end of the support plate is installed on the connecting plate, and the other end of the support plate abuts against the inner wall of the steel pipe body and moves on the inner wall of the steel pipe body.

[0008] Further configured, the support plate includes a top plate, an intermediate adjusting plate and a bottom plate arranged in sequence, the bottom plate is fixed on the connecting plate, the two ends of the intermediate adjusting plate are detachably connected to the top plate and the bottom plate respectively, the top plate abuts against the inner wall of the steel pipe body, and the top plate moves on the inner wall of the steel pipe body.

[0009] A further configuration is provided, wherein one end of the top plate has a receiving groove, and the receiving groove is provided with a spring, a support plate and a ball. The two ends of the spring are fixedly connected to the inner wall of the bottom of the receiving groove and the support plate, respectively. The ball moves on the support plate and is movably connected to the opening of the receiving groove. The ball extends out of the opening of the receiving groove and rolls on the inner wall of the steel pipe body. The ball abuts against the inner wall of the steel pipe body. The diameter of the opening of the receiving groove is smaller than the diameter of the ball.

[0010] A further configuration is provided, wherein a T-shaped block is fixed on the pallet, and a T-shaped groove is formed on the ball to slide and connect with the T-shaped block. The T-shaped groove engages with the T-shaped block and is arranged around the ball.

[0011] A further configuration is provided, wherein a locking block is installed at the other end of the top plate, and a locking block is also fixed on the bottom plate. Both ends of the intermediate adjustment plate are provided with locking slots that cooperate with the locking blocks. The locking slot at one end of the intermediate adjustment plate engages with the locking block on the top plate, and the locking slot at the other end of the intermediate adjustment plate engages with the locking block on the bottom plate.

[0012] A further configuration is provided, wherein the connecting plate of the adjacent compression support module is equipped with a threaded connection to the other end of the connecting rod in a fixed screw tube.

[0013] The upper part of the receiving groove is frustum-shaped, and the lower part of the receiving groove is cylindrical.

[0014] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0015] 1. By using a pressure-resistant support structure to support the steel pipe from the inside, the pressure resistance of the steel pipe is improved. This prevents the steel pipe from deforming under pressure, exceeding the standard ovality, or having local indentations or dents when stacked during transportation and storage. Furthermore, the pressure-resistant support structure can be removed when the steel pipe is put into use without affecting its operation.

[0016] 2. By adjusting the combination of different numbers of compressive support modules and connecting rods, the length of the compressive support structure can be adjusted according to the needs of steel pipes of different lengths, so as to adapt to steel pipes of different lengths, with high adaptability and strong practicality.

[0017] 3. Based on the different inner diameters of the steel pipes, select an appropriate length of intermediate adjustment plate and assemble it together with the bottom plate and top plate to form a support plate that is compatible with the corresponding inner diameter of the steel pipe. This allows the compression support module to be adapted to support steel pipes with different inner diameters, so that the compression support structure can be used for steel pipes with various inner diameters, further improving compatibility and enhancing practicality.

Detailed Implementation

[0023] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0024] A pressure-resistant steel pipe with a pressure-resistant support structure includes a steel pipe body 100, and a pressure-resistant support structure 200 is provided inside the steel pipe body 100. The pressure-resistant support structure 200 is fitted with the inner wall of the steel pipe body 100. The pressure-resistant support structure 200 includes a plurality of pressure-resistant support modules 201 and a plurality of connecting rods 202. The plurality of connecting rods 202 are respectively arranged between every two adjacent pressure-resistant support modules 201. The pressure-resistant support module 201 includes a connecting plate 1 and a plurality of support plates 2 evenly arranged around the connecting plate 1. One end of the connecting rod 202 is fixedly connected to the connecting plate 1. A threaded connection is installed on the connecting plate 1 of the adjacent pressure-resistant support module 201 to the other end of the connecting rod 202 and fixed to a fixed threaded tube 7.

[0025] The support plate 2 includes a top plate 21, an intermediate adjustment plate 22, and a bottom plate 23 arranged sequentially. The bottom plate 23 is fixed on the connecting plate 1. A locking block 5 is installed on the other end of the top plate 21, and a locking block 5 is also fixed on the bottom plate 23. Both ends of the intermediate adjustment plate 22 have locking grooves 6 that cooperate with the locking blocks 5. The locking groove 6 at one end of the intermediate adjustment plate 22 engages with the locking block 5 on the top plate 21, and the locking groove 6 at the other end of the intermediate adjustment plate 22 engages with the locking block 5 on the bottom plate 23, so that the two ends of the intermediate adjustment plate 22 can be disassembled and connected to the top plate 21 and the bottom plate 23 respectively.

[0026] One end of the top plate 21 has a receiving groove 3. The upper part of the receiving groove 3 is frustum-shaped, and the lower part is cylindrical. The receiving groove 3 is equipped with a spring 24, a support plate 25, and a ball bearing 26. The two ends of the spring 24 are fixedly connected to the inner wall of the bottom of the receiving groove 3 and the support plate 25, respectively. The ball bearing 26 moves on the support plate 25 and is movably connected to the opening of the receiving groove 3. The ball bearing 26 extends out of the opening of the receiving groove 3 and rolls on the inner wall of the steel pipe body 100. The ball bearing 26 abuts against the inner wall of the steel pipe body 100. The diameter of the opening of the receiving groove 3 is smaller than the diameter of the ball bearing 26, so that the other end of the support plate 2 abuts against the inner wall of the steel pipe body 100 so that the anti-compression support module 201 can support the steel pipe body 100. The other end of the support plate 2 moves on the inner wall of the steel pipe body 100 so that the anti-compression support structure 200 can be inserted into the steel pipe body 100 for use and the anti-compression support structure 200 can be easily removed.

[0027] Working principle: First, the compression support structure 200 is placed inside the steel pipe body 100. Since the ball bearings 26 of the support plate 2 are in contact with the inner wall of the steel pipe body 100 and can roll, the compression support structure 200 can be smoothly placed inside and removed from the steel pipe body 100 without being difficult to install or remove due to excessive friction.

[0028] After the compression support structure 200 is placed, several compression support modules 201 are connected together by connecting rods 202. One end of the connecting rod 202 is fixedly connected to the connecting plate 1, and the other end is connected to the fixed screw tube 7 by threads, so that the entire compression support structure 200 forms a stable support system within the steel pipe body 100.

[0029] After the compression support structure 200 is placed into the steel pipe body 100, in each compression support module 201, the two ends of the spring 24 in the support plate 2 are fixedly connected to the bottom inner wall of the receiving groove 3 and the support plate 25, respectively. The ball 26 on the support plate 25 extends out of the groove opening of the receiving groove 3 and rolls against the inner wall of the steel pipe body 100, with 3 / 4 of the volume of the ball 26 extending out of the receiving groove 3. At this time, the spring 24 is compressed and the surface of the ball 26 engages with the groove opening of the receiving groove 3, so that the ball 26 tightly abuts against the inner wall of the steel pipe body 100, thereby achieving the other end of the support plate 2 being connected to the inner wall of the steel pipe body 100. The wall's resistance allows the compression support module 201 to effectively support the steel pipe body 100. This compression support structure 200 provides internal support to the steel pipe body 100, significantly improving the steel pipe's compressive strength. This ensures that during transportation and storage, even when steel pipes are stacked, the presence of the compression support structure 200 prevents problems such as compression deformation, excessive ellipticity, localized indentations, or dents. Furthermore, the compression support structure 200 can be easily removed when the steel pipe is put into use, without affecting its normal operation, thus guaranteeing the quality and performance of the steel pipe.

[0030] When the ball bearing 26 abuts against the inner wall of the steel pipe body 100, it moves at the opening of the receiving groove 3, which facilitates the rolling of the ball bearing 26 on the inner wall of the steel pipe body 100, thereby making it easy for the compression support structure 200 to be smoothly placed into the steel pipe body 100 or to adjust the position of the compression support structure 200 within the steel pipe body 100.

[0031] Depending on the length of the steel pipe, the number of compression support modules 201 and connecting rods 202 can be adjusted to form compression support structures 200 of different lengths, thus adapting to steel pipes of varying lengths. This results in high adaptability and practicality. For example, for longer steel pipes, the number of compression support modules 201 and connecting rods 202 can be increased; for shorter steel pipes, the number of compression support modules 201 and connecting rods 202 can be decreased.

[0032] For steel pipes with different inner diameters, an intermediate adjusting plate 22 of appropriate length can be selected. The slots 6 at both ends of the intermediate adjusting plate 22 can be engaged with the blocks 5 on the bottom plate 23 and the top plate 21, respectively. This allows the intermediate adjusting plate 22 to be assembled with the bottom plate 23 and the top plate 21 to form a support plate 2 that is adapted to the inner diameter of the corresponding steel pipe. This achieves the purpose of adjusting the length of the support plate 2, so that the total length of the support plate 2 is adapted to the inner diameter of the corresponding steel pipe to support it. This makes the compressive support structure 200 suitable for steel pipes with various inner diameters, further improving compatibility and enhancing practicality.

[0033] A T-shaped block 41 is fixed on the tray 25, and a T-shaped groove 4 is opened on the ball 26 to slide and connect with the T-shaped block 41. The T-shaped groove 4 is engaged with the T-shaped block 41 and is arranged around the ball 26.

[0034] During the rolling process, the T-block 41 slides in the T-groove 4 without affecting the rolling of the ball 26, and ensures that the ball 26 will not deviate or wobble when rolling, so that the ball 26 will always be in stable contact with the inner wall of the steel pipe body 100, thereby improving the stability of the support structure 200 for the steel pipe body 100. In addition, the engagement between the T-groove 4 and the T-block 41 prevents the ball 26 from falling out of the groove of the receiving groove 3, further ensuring the stable rolling of the ball 26.
