Description

Technical Field

[0001] The utility model belongs to the field of pipeline welding, and particularly relates to a novel pipe aligner with precise adjustment. Background Technique

[0002] A pipe aligner is an important device used in pipeline construction and maintenance. Especially, it plays a key role in the operation of pipe alignment. The main function of the pipe aligner is to fix the pipe ends of two pipes, ensuring the quality and speed of pipe connection. This is crucial for ensuring the quality and progress of pipeline projects.

[0003] In the existing pipeline connection and alignment technologies, commonly used pipe aligners usually rely on manual alignment or simple mechanical devices to achieve pipeline connection. However, these traditional pipe aligners have certain deficiencies in terms of precision control and operation convenience. They cannot fix the pipes individually during use, reducing the connection precision and stability. It is difficult to apply to pipes with different diameters and materials, and the versatility is poor. Moreover, the structures of some aligners are relatively rigid and lack flexibility, making it difficult to adapt to thermal expansion and contraction of pipes or environmental vibrations, which may lead to stress concentration at the connection part, increasing the leakage risk or causing connection failure.

[0004] Therefore, a novel pipe aligner with precise adjustment is proposed, which has the advantages of convenient disassembly and assembly, easy later maintenance, strong versatility, being applicable to pipes with different diameters, flexible docking structures, reducing stress concentration and improving connection stability. Summary of the Utility Model

[0005] In order to overcome the problems that the existing pipe aligners cannot fix the pipes individually during use, are difficult to apply to pipes with different diameters and materials, and have poor stability.

[0006] The technical solution of the utility model is as follows: A novel pipe aligner with precise adjustment, including a first semi-circular block; there are two first semi-circular blocks, and the two first semi-circular blocks are flush with each other up and down. A plurality of uniformly distributed first support rods are fixedly connected between the two ends of the two first semi-circular blocks close to each other. A second semi-circular block is arranged on the right side of the first semi-circular block. A plurality of uniformly distributed second support rods are fixedly connected between the two ends of the second semi-circular block close to each other. A plurality of first threaded grooves are respectively formed through the side walls of the first support rods and the second support rods. Fixing plates are movably installed at the upper and lower ends of the openings of the first semi-circular block and the second semi-circular block close to each other. Fixing components are arranged on the fixing plates. Adjusting components are arranged on the first threaded grooves. Clamping components are arranged on the adjusting components.

[0007] Preferably, by inserting the two butt - jointed pipes into the circular area formed by the first semi - circular block and the second semi - circular block from opposite directions, according to the diameter of the pipes, first manually rotate the square block to drive the bolt closer to the outer wall of the pipe until one end of the clamping block fits against the outer wall of the pipe. Then, use a tool to insert it into the notch and rotate it for fixation. This is convenient for adjustment and improves work efficiency. It is applicable to the butt - joint of various different pipe diameters. Since there are multiple first threaded grooves on the first support rod, the bolt can be inserted into the inner walls of different first threaded grooves to individually fix the two pipes, ensuring stable positions and reducing displacement errors. When the pipes shake during the butt - joint process, the clamping block drives the threaded post to squeeze the spring. At this time, the sliding post slides inside the second cylinder. The spring can effectively absorb and attenuate the vibration and impact during the pipe butt - joint, improving stability. It solves the problems that the existing pipe aligner cannot individually fix the pipes during use, is difficult to apply to pipes of different diameters and materials, and has poor stability.

[0008] Preferably, the fixing assembly includes a second threaded groove, a threaded rod, a first nut, and a second nut. A second threaded groove penetrating the first semi - circular block and the second semi - circular block is opened at the upper end of the fixing plate. The threaded rod is threadedly installed on the inner wall of the second threaded groove. The first nut and the second nut are threadedly installed on the upper and lower ends of the outer wall of the threaded rod. The threaded rod passes through the first semi - circular block and the second semi - circular block and is threadedly fixed by the first nut and the second nut. During use, by bringing the openings of the first semi - circular block and the second semi - circular block closer to each other, take out the fixing plate and place it at the upper and lower ends where the first semi - circular block and the second semi - circular block are close to each other. The threaded rod passes through the first semi - circular block, the second semi - circular block, and the second threaded groove, and the upper and lower ends of the outer wall of the threaded rod are threadedly fixed by the first nut and the second nut. It is convenient for disassembly and assembly and is conducive to later maintenance.

[0009] Preferably, the adjusting assembly includes a bolt, a square block, and a notch. The bolt is threadedly installed on the inner wall of the first threaded groove. One end of the bolt is fixedly connected to the square block, and a notch is opened through the upper end of the square block. During use, first manually rotate the square block to drive the bolt closer to the outer wall of the pipe, and then use a tool to insert it into the notch and rotate it for fixation to improve work efficiency.

[0010] Preferably, the clamping assembly includes a first cylinder and a third threaded groove. The other end of the bolt is threadedly installed with a first cylinder. A third threaded groove is opened at one end of the first cylinder close to the bolt. The outer wall of the bolt is adapted to the inner wall of the third threaded groove. During use, by threadedly installing the first cylinder and the bolt, it is convenient for disassembly and assembly.

[0011] Preferably, the clamping assembly further includes a second cylinder, a sliding column, a spring, a threaded column, a clamping block and a fourth threaded groove. The inner wall of the first cylinder is fixedly connected with the second cylinder. The inner wall of the second cylinder is slidably installed with the sliding column. The inner wall of the first cylinder is fixedly connected with the spring, and the spring is located outside the second cylinder. One end of the sliding column away from the first cylinder is fixedly connected with the threaded column. One end of the threaded column away from the first cylinder is threadedly installed with the clamping block. One end of the clamping block close to the first cylinder is provided with a fourth threaded groove, and the inner wall of the fourth threaded groove is adapted to the outer wall of the threaded column. When in use, the end of the clamping block away from the first cylinder is tightly attached to the outer wall of the pipeline. When the pipeline shakes during docking, the clamping block drives the threaded column to squeeze the spring. At this time, the sliding column slides inside the second cylinder. The spring can effectively absorb and attenuate the vibration and impact during pipeline docking, reduce the influence on the pipeline and the connection part, extend the service life, and the clamping block is threadedly installed with the threaded column, which is convenient for replacing and maintaining the clamping block.

[0012] Preferably, the end of the clamping block away from the first cylinder is a concave structure. When in use, the concave structure at one end of the clamping block can improve the friction with the pipeline surface and enhance the stability.

[0013] Preferably, the first semi-circular block and the second semi-circular block have the same structure, and the first support rod and the second support rod are symmetric about the center point of the fixed plate. When in use, the symmetry of the first support rod and the second support rod reduces the risk of deformation or inclination caused by uneven load, thereby improving the overall stability. The same structure of the first semi-circular block and the second semi-circular block reduces the complexity of the design and can reduce the manufacturing cost.

[0014] The beneficial effects of the present utility model:

[0015] 1. By inserting the two butt-jointed pipelines into the circular area formed by the first semi-circular block and the second semi-circular block from opposite directions respectively, according to the diameter of the pipeline, first manually rotate the square block to drive the bolt to approach the outer wall of the pipeline until one end of the clamping block fits the outer wall of the pipeline, and then use a tool to insert it into the notch and rotate it for fixation. The adjustment is convenient, the work efficiency is improved, and it is applicable to the docking of various different pipeline diameters, solving the problem that the existing pipe aligner is difficult to apply to pipelines with different diameters and materials during use.

[0016] 2. By providing a plurality of first threaded grooves on the first support rod, the bolt can be inserted into the inner wall of different first threaded grooves to fix the two pipelines separately, ensuring stable position and reducing displacement error. When the pipeline shakes during docking, the clamping block drives the threaded column to squeeze the spring. At this time, the sliding column slides inside the second cylinder. The spring can effectively absorb and attenuate the vibration and impact during pipeline docking, improve the stability, and solve the problems that the existing pipe aligner cannot fix the pipeline separately and has poor stability during use;

[0017] 3. By bringing the openings of the first semi-circular block and the second semi-circular block closer to each other, take out the fixing plate and place it at the upper and lower ends where the first semi-circular block and the second semi-circular block are close to each other. The threaded rod passes through the first semi-circular block, the second semi-circular block and the second threaded groove. The outer walls of the upper and lower ends of the threaded rod are fixed by the first nut and the second nut in a threaded manner. The first cylinder is installed in a threaded manner with the bolt, which is convenient for disassembly and assembly and is convenient for later maintenance. By using the fact that one end of the clamping block is a concave structure, the friction with the surface of the pipeline can be increased, and the stability can be enhanced.

[0030] Through the above steps, during use, first bring the openings of the first semi-circular block 1 and the second semi-circular block 3 close to each other. Take out the fixing plate 6 and place it at the upper and lower ends where the first semi-circular block 1 and the second semi-circular block 3 are close to each other.
