Description

Technical Field

[0001] The present invention mainly relates to the technical field of pipeline pairing, and specifically to a pipeline intelligent pairing device and method based on big data analysis. Background Art

[0002] When the pipes are paired, when the nominal diameter of the pipe is less than 100mm, the allowable deviation of the straightness of the pipe is 1mm; when the nominal diameter of the pipe is greater than or equal to 100mm, the allowable deviation of the straightness of the pipe is 2mm, but the allowable deviation of the entire length is 10mm. When the pipes are paired, the center lines of the pipes should be in a straight line, and the gap between the ends should also meet the requirements. When the pipes are paired, the inner walls are flush, the misalignment of the inner walls should not exceed 10% of the wall thickness, and should not be greater than 2mm, and forced pairing is not allowed. Therefore, it is necessary to adjust the straightness of the pipes during the pairing process, and the accuracy requirements are high. Since there will be misalignment when the pipes are paired, and the center lines must be kept in a straight line, the pipes need to be finely adjusted so that the misalignment meets the requirements, and the center line deviation is also controlled within the error range. Since the pipes cannot be paired forcibly, it is necessary to accurately adjust the position of the pipes and find the best position for the pipes for pairing. Therefore, the pairing of pipes needs to meet the various requirements in the pipe pairing process through intelligent pairing devices and methods.

[0003] At present, in the prior art, a patent with application publication number CN 112222589 A discloses a pipeline prefabrication intelligent assembly system, including a track assembly, at least one assembly head arranged on the track assembly, the assembly head can be installed with a standardized pipe module containing pipes to be processed, and the horizontal, longitudinal and vertical positions of the pipe module are adjusted by a first moving assembly, a second moving assembly and a third moving assembly to match the pipe to be processed installed on the support trolley, and the assembly and welding of the pipe to be processed with the pipe to be processed are realized by a rotary assembly, a detection assembly and a welding assembly. The processing system realizes automation and intelligence in the assembly and welding process, and can be applied to pipes of different types and specifications through standardized pipe modules. However, it needs to carry out a complete set of control operation procedures for each pipe assembly, and for pipe groups of the same specifications, the detection and control work cannot be reduced, and the degree of intelligence needs to be improved. In addition, its device is relatively complex, and it is inconvenient to carry out assembly work. Summary of the invention

[0006] Furthermore, a top iron ring is provided on the inner side of the back ring, and the top iron ring is used to be sleeved on the pipeline, and the jacks are located on the outer peripheral side of the top iron ring at equal intervals.

[0007] Furthermore, the top iron ring and the back iron ring each include two detachable semicircular components.

[0008] Furthermore, a rubber ring is provided on the inner side of the top iron ring and is sleeved on the pipe, and at least four mounting holes for mounting a jack are provided on the back ring; a hydraulic cylinder for driving the scanning and detection device to move radially along the back ring is installed on the back ring to which the scanning and detection device is connected, and the scanning and detection device is connected to the working end of the hydraulic cylinder.

[0009] Furthermore, the moving mechanism is detachably connected to the back ring.

[0010] Furthermore, the top surface of the moving mechanism is an arc-shaped surface adapted to the bottom of the back ring, and the bottom surface of the moving mechanism is equipped with a moving mechanism driving wheel.

[0011] Furthermore, a guide rail extending along the curvature of the back ring connected to the scanning and detecting device is installed on the outer ring surface, and a traveling trolley is installed on the guide rail. The scanning and detecting device is connected to the traveling trolley. The central angle corresponding to the guide rail is greater than 180°, and the traveling trolley is electrically connected to the overall control system.

[0012] A further improvement to the above scheme is that the side of the walking trolley facing away from the back circle is connected to a lifting block through an elastic member, and an electric telescopic rod extending from its side is provided inside the lifting block, and a limiting protrusion is fixed to the end of the electric telescopic rod, and the height of the limiting protrusion is greater than the diameter of the working end of the electric telescopic rod.

[0013] As a further improvement to the above solution, a hydraulic cylinder is installed on the lifting block, and the scanning detection device and the welding gun are both connected to the working end of the hydraulic cylinder.

[0014] The present invention also provides a pipeline intelligent pairing method based on big data analysis, which uses the above-mentioned pipeline intelligent pairing device based on big data analysis; the pipeline intelligent pairing method comprises the following steps: S1. Lift the two pipes to be assembled onto two sets of supporting mechanisms respectively; S2.

When the pipelines of the same specification are subsequently paired, the overall control system uses a neural network convolution analysis and intelligently provides a pairing adjustment plan based on the pairing database. Compared with the prior art, the present invention can automatically provide an adjustment plan based on the previous big data analysis when pairing pipelines, and does not need to perform a complete set of control operation processes, thereby reducing the detection and control work and significantly improving the intelligence of the pairing.

[0016] The present invention is provided with a moving mechanism and a jack. When used, the moving mechanism can realize a large adjustment of the pipeline pair, and the jack can realize a fine adjustment, thereby realizing a high-precision adjustment effect and meeting various requirements of the pipeline pair. In addition, the scanning detection device can detect the relevant data of the groove of the paired pipeline in real time, and then automatically drive the moving mechanism and the jack to make adjustments, which can realize the adjustment of other data such as the gap and straightness at the same time, thereby realizing the adjustment work of the intelligent pairing, and is also conducive to improving the safety of the pairing.

[0017] The pairing device provided by the present invention comprises several support mechanisms of the same structure, and a scanning detection device is only arranged on one of the support mechanisms, and the support mechanism comprises a ring structure mounted on the pipeline to position the pipeline and a moving mechanism for supporting the ring structure and driving it to move greatly in the horizontal plane, and then the pipeline is fine-tuned by a jack arranged inside the ring structure. Therefore, the structure of the pairing device of the present invention is relatively simple, and the pairing work is relatively convenient.

[0018] The assembly device provided by the present invention includes at least two supporting mechanisms. For very short pipes, one supporting mechanism can be used to carry the pipes. When two supporting mechanisms are used to carry one pipe, the distance between the two supporting mechanisms can be adjusted to adapt to pipes of different lengths. For particularly long pipes, the number of supporting mechanisms can be increased for carrying the pipes, which is more convenient to use.

[0029] Embodiment 2: This embodiment differs from Embodiment 1 in that: In this embodiment, a rubber ring is provided on the surface of the pipe 1, and the top iron ring 2 is mounted on the outside of the rubber ring and fits tightly to the rubber ring. The size of the rubber ring is adjusted to ensure that the top iron ring 2 can be suitable for pipes of different specifications; a plurality of mounting holes for mounting the jack 4 are provided on the back ring 3, and the number, model and specification of the jack 4 are adjusted to ensure that the back ring 3 can be suitable for pipes of different specifications; a hydraulic cylinder 16 for driving the scanning and detection device 8 to move radially along the back ring 3 is installed on the back ring 3 to which the scanning and detection device 8 is connected, and the scanning and detection device 8 is connected to the working end of the hydraulic cylinder 16, and the radial position of the scanning and detection device 8 on the back ring 3 can be adjusted by the hydraulic cylinder 16, so that it can adapt to pipes of different specifications.

[0030] In this embodiment, the central angle corresponding to the guide rail 15 is 200°.

[0031] The rest is the same as the first embodiment.

[0032] Embodiment 3: This embodiment differs from Embodiment 1 in that: In this embodiment, please refer to the attached Figure 1 -Attached Figure 4The side of the walking trolley 11 facing away from the back circle 3 is connected to a lifting block 18 through an elastic member 17 (which can be a sponge or a spring). The lifting block 18 is provided with an electric telescopic rod 14 extending from its side. A limiting protrusion 19 is fixed to the end of the electric telescopic rod 14. The height of the limiting protrusion 19 is greater than the diameter of the working end of the electric telescopic rod 14. The side of the walking trolley 11 is connected to a card plate 20 extending to the side of the lifting block 18. The card plate 20 is provided with a through hole 201 whose height is just adapted to the limiting protrusion 19. The card plate 20 is used to hinder the lifting and lowering movement of the lifting block 18; the scanning detection device At least three limit blocks 13 are provided at equal intervals along the circumference of the back ring 3 connected to the device 8.

At this time, the limiting protrusion 19 is just stuck in the through-hole 201 of the clamping plate 20, so that the lifting block 18 cannot be lifted or moved relative to the walking trolley 11. In the process of the walking trolley 11 driving the scanning and detection device 8 to rotate around the pipeline 1, the scanning and detection device 8 can be prevented from vibrating and deviating under the action of the elastic member 17 and remain stable, so as to achieve stable measurement of the misalignment of the assembly at different positions of the pipeline 1; after the two pipelines 1 are aligned, the welding gun 12 is used to spot weld the splicing position of the pipeline 1, specifically: first start the electric telescopic rod 14 to extend, at this time, the working end of the electric telescopic rod 14 is located at the through-hole 2 01, because the diameter of the electric telescopic rod 14 is small and the opening 201 is wide, that is, the electric telescopic rod 14 can be lifted and moved in the opening 201, so that the lifting block 18 can be lifted and moved relative to the walking trolley 11, and then in the process of the walking trolley 11 driving the welding gun 12 to rotate around the pipe 1, the limit protrusion 19 rotates accordingly, and when the limit protrusion 19 turns to the position of the limit block 13, the protruding structure of the lateral part of the limit block 13 will force the limit protrusion 19 to move toward the walking trolley 11, and the lifting block 18 moves accordingly, driving the welding gun 12 to apply pressure to the joint of the pipe 1, and cooperate with the welding heat of the welding gun 12 to achieve spot welding at one place. Similarly, after completing at least three spot weldings, the spot welding fixation of the grouped pipe 1 is completed. That is, the existing walking trolley 11 is used to realize automatic spot welding, without manual operation, and further improves intelligence; and the device structure is relatively simple, easy to use, and does not need to rotate the pipe 1, which can ensure the stability of the pipe 1 group state.

A pipeline intelligent pairing method based on big data analysis, characterized in that: The pipeline intelligent pairing device based on big data analysis according to any one of claims 1 to 9 is adopted; the pipeline intelligent pairing method comprises the following steps: S1. hoisting two pipes (1) to be assembled onto two sets of supporting mechanisms respectively; S2, adjusting the distance between the two pipes (1) by driving the moving mechanism (5) so that the gap between the two pipes (1) is within a required control range; S3, the scanning detection device (8) detects the pipeline groove; S4, based on the real-time groove data of the pipe (1) pair provided by the scanning detection device (8), first adjust the moving mechanism (5) so that the center lines of the two pipes (1) are in a straight line, and then adjust the jack (4) to make the pipes (1) move slightly, so that the misalignment between the pipes (1) is controlled within the requirements of the standard and specification; S5. After the misalignment between the pipes (1) meets the requirement, the jack (4) and the moving mechanism (5) are locked to ensure that the data of each pairing between the two pipes (1) do not change, and then the pipes (1) are fixed by spot welding; S6, by pairing pipelines (1) of the same specification, continuously accumulating initial data, adjustment process, adjustment data and final data of the pairing of pipelines (1), and establishing a pipeline (1) pairing database in the overall control system (10); S7. When the pipelines (1) of the same specification are subsequently paired, the overall control system (10) intelligently provides a pairing adjustment plan through neural network convolution analysis and based on the pairing database, and starts the moving mechanism driver (6) and / or the hydraulic control device (9) to perform pairing adjustment.
