Description

Technical Field

[0001] The utility model belongs to the field of pipeline detection, and particularly relates to a pipeline compressive strength detection device. Background Art

[0002] In modern industrial production, pipelines, as important components for transporting fluids (such as gases, liquids, etc.), their compressive properties are directly related to the safe and stable operation of the entire system. Whether it is the oil and gas transportation pipelines in the petrochemical industry or the water pipes in the building water supply and drainage system, they all need to have good compressive capacity to prevent accidents such as pipeline rupture and leakage caused by excessive pressure.

[0003] For example, a special equipment pressure pipeline compressive strength detection device disclosed in a Chinese patent (publication number: CN220772784U) includes a placement plate. Both sides of the surface of the placement plate are fixedly installed with support plates through bolts. Threaded holes are opened inside the support plates, and a first threaded rod is threadedly connected to the surface of the threaded holes. In this special equipment pressure pipeline compressive strength detection device, through the settings of the support plates, the first threaded rod, the fixing clips, and the rubber pads, the staff can place the pressure pipeline on the placement plate. By rotating the first threaded rod, it drives the fixing clips to approach the pressure pipeline. The rubber pads provided on the surfaces of the fixing clips can increase the fixing property of the pressure pipeline. By using the fixing clips to clamp and fix the surface of the pressure pipeline, since there are fixing clips for fixing provided on both sides of the surface of the placement plate, both ends of the pressure pipeline can be fixed, which is beneficial to fixing the pressure pipeline.

[0004] However, some problems are exposed in the actual application of this device: on the one hand, its fixing operation is relatively cumbersome, and the staff needs to manually rotate the first threaded rod to adjust the position of the fixing clips, consuming time and manpower; on the other hand, during the fixing process, since the fixing force is difficult to accurately control, it is easy to cause the pipeline to deform due to excessive force, affecting the accuracy of the detection results; in addition, this device can only detect a single position of the pipeline and cannot comprehensively evaluate the compressive properties of the pipeline in the circumferential and axial directions, and cannot meet the requirements of strict control of pipeline quality in actual production.

[0005] Therefore, a pipeline compressive strength detection device is needed to solve the above problems. Summary of the Utility Model

[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0031] Embodiment 1

[0032] As Figures 1 - 6 shown, the embodiment of the present utility model provides a pipeline compressive strength detection device, including a support component 1, an adjusting component 2, two rotating components 3, two clamping components 4 and a detection component 5. The support component 1 includes a base 11, and a support frame 13 is connected to the base 11. The adjusting component 2 is connected inside the base 11;

[0033] The rotating component 3 includes a movable frame 31. Both ends of the adjusting component 2 are connected to the movable frame 31. A first motor 32 is connected to the side of each of the two movable frames 31 away from each other. A rotating rod 33 is connected to the ends of the two first motors 32 close to each other. The rotating rod 33 is rotatably connected inside the movable frame 31. A first gear 34 is connected to the outside of the rotating rod 33. The first gear 34 meshes with a second gear 35. A rotating tube 36 is connected to the side of each of the two second gears 35 close to each other. The two rotating tubes 36 are both rotatably connected inside the movable frame 31. Two guide grooves 37 are provided inside the second gear 35;

[0034] The detection component 5 includes a second threaded rod 51. The second threaded rod 51 is rotatably connected inside the support frame 13. One end of the second threaded rod 51 is connected to a third motor 52. The third motor 52 is connected to one side of the support frame 13. A threaded seat 53 is threadedly connected to the outside of the second threaded rod 51. A hydraulic cylinder 54 is connected to the bottom of the threaded seat 53. A detection head 55 is connected to the bottom end of the hydraulic cylinder 54.

[0035] In this embodiment, when the device needs to be used, first, the adjusting member 2 is controlled according to the size of the pipeline 6 to be detected. The driving member can be set as an electric push rod or a cylinder. The driving member is controlled to extend. The extended driving member can drive the distance between the two clamping assemblies 4 to be adjustable. Then, the two clamping assemblies 4 with adjustable positions can clamp pipelines 6 of different sizes. After the two clamping assemblies 4 clamp and fix the pipeline 6, the two first motors 32 are controlled to work. The working first motors 32 drive the first gears 34 to rotate through the rotating rods 33. The rotating first gears 34 drive the second gears 35 to rotate. The rotating second gears 35 drive the rotating pipes 36 to rotate in the movable frame 31. The two rotating second gears 35 drive the pipeline 6 to rotate through the clamping assemblies 4. Then, the working detection assembly 5 can detect each position of the pipeline 6 in the circumferential direction;

[0036] The third motor 52 is controlled to work. The working third motor 52 drives the second threaded rod 51 to rotate in the support frame 13. The rotating second threaded rod 51 drives the threaded seat 53 to rotate in the through groove 14. The rotating second threaded rod 51 drives the hydraulic cylinder 54 to move through the threaded seat 53. The moving hydraulic cylinder 54 drives the detection head 55 to move synchronously along the axial direction of the second threaded rod 51, so that the moving detection head 55 can detect the top part of the pipeline 6 in the axial direction directly below it.

[0037] Specifically, a through groove 14 is opened at the top of the support frame 13. The threaded seat 53 is slidably connected in the through groove 14. The cross-sectional shape of the through groove 14 is set as a cross shape.

[0038] In this embodiment, the cross-shaped through groove 14 can limit the movement of the moving threaded seat 53. When the working hydraulic cylinder 54 drives the detection head 55 to detect the compressive performance of the pipeline 6, the threaded seat 53 slidably connected in the through groove 14 can be fixed under the action of the reaction force of the hydraulic cylinder 54, so that the threaded seat 53 is not likely to apply an upward force to the second threaded rod 51 under the action of the reaction force of the hydraulic cylinder 54, thereby effectively avoiding the deformation of the second threaded rod 51, ensuring that the threaded seat 53 can move normally and stably, and further ensuring the smooth progress of the detection work.

[0039] Specifically, limiting grooves 12 are opened on both sides of the base 11. The movable frame 31 is slidably connected in the limiting grooves 12.

[0040] In this embodiment, the limiting grooves 12 can limit the movement of the moving movable frame 31, ensure the accuracy and stability of the adjustment of the distance between the two clamping assemblies 4, and provide a reliable guarantee for the subsequent clamping and fixing of the pipeline 6.

[0041] Specifically, the detection head 55 is arranged directly above the middle part of the pipeline 6, and the detection head 55 is arranged between the two second gears 35.

[0042] In this embodiment, since a pressure sensor is provided at the bottom of the detection head 55, when the hydraulic cylinder 54 applies a constant pressure to the detection head 55, this constant pressure can be adjusted in real time. After the detection head 55 contacts the pipeline 6, the pressure sensor at the bottom of the detection head 55 can detect the pressure received. When the pipeline 6 deforms under the extrusion of the detection head 55, the pressure detected by the pressure sensor in the detection head 55 will fluctuate. Then, the deformation of the pipeline 6 can be known through the fluctuating pressure, and the deformation condition of the pipeline 6 can also be known by observation.

[0043] Embodiment 2

[0044] Please refer to Figures 1 - 5 , the difference between this embodiment and Embodiment 1 is that: the clamping assembly 4 includes a second motor 41, the second motor 41 is connected inside the rotating pipe 36, the output shafts at both ends of the second motor 41 are both connected to the first threaded rod 42, the first threaded rod 42 is rotatably connected inside the rotating pipe 36, and the first threaded rod 42 is externally threaded with a first clamping plate 43 and a second clamping plate 44. A plurality of first clamping plates 43 are lapped on the inner wall of the pipeline 6, and a plurality of second clamping plates 44 are lapped on the outer surface of the pipeline 6;

[0045] In this embodiment, control the second motor 41 to work. The working second motor 41 drives the two first threaded rods 42 to rotate inside the rotating pipe 36. The first threaded rod 42 rotating forward drives the first clamping plate 43 and the second clamping plate 44 to approach each other. The approaching first clamping plate 43 and second clamping plate 44 respectively contact the inside and outside of the pipeline 6, and then the first clamping plate 43 and the second clamping plate 44 can fix the pipeline 6. And because the first clamping plate 43 and the second clamping plate 44 respectively clamp the inside and outside of the pipeline 6, this two-way clamping method can distribute the fixing force more evenly compared with the traditional one-way fixing method, effectively avoiding the deformation of the pipeline 6 caused by uneven fixing force, and laying a foundation for accurately detecting the compressive performance of the pipeline 6 subsequently.

[0046] Specifically, the shapes of the first clamping plate 43 and the second clamping plate 44 are both set to be arc-shaped, and the first clamping plate 43 and the second clamping plate 44 are slidably connected in the corresponding guide grooves 37.

[0047] In this embodiment, the guide grooves 37 can limit the moving first clamping plate 43 and second clamping plate 44. The first clamping plate 43 and the second clamping plate 44 can slide smoothly along a predetermined track, accurately contact the inner wall and outer wall of the pipeline 6 and apply a fixing force, improving the reliability and stability of the clamping and fixing.

[0048] Specifically, two parts of the first threaded rod 42 with opposite thread directions are provided on the outside, and the first clamping plate 43 and the second clamping plate 44 are respectively arranged outside the threads with opposite thread directions.

[0049] In this embodiment, the rotating first threaded rod 42 can drive the first clamping plate 43 and the second clamping plate 44 to approach or move away from each other. In this way, the distance between the clamping plates and the pipe 6 can be conveniently adjusted to meet the clamping requirements of pipes 6 with different diameters. At the same time, the design of opposite thread directions enables the first clamping plate 43 and the second clamping plate 44 to maintain synchronization during movement, ensuring that the clamping force on the pipe 6 is evenly distributed and further improving the clamping and fixing effect.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
