Description

Technical Field

[0001] This utility model relates to the field of special equipment testing technology, specifically a special equipment pressure pipeline quality testing device. Background Technology

[0002] In industrial production, the quality of pressure pipelines for special equipment is directly related to production safety and efficiency. Pressure pipelines may develop defects such as corrosion, cracks, and deformation during long-term use, so regular quality inspections are necessary.

[0003] The existing patent document CN221425567U discloses a special equipment pressure pipeline quality inspection device. This utility model can adjust the distance between the clamping mechanisms, can be adaptively adjusted according to the length of the pressure pipeline, and can measure the thickness of the pipeline. It is easy to use.

[0004] However, existing special equipment pressure pipeline quality inspection devices have certain limitations when carrying out inspection operations. First, the inspection components of most inspection devices are in fixed positions, making it inconvenient to move flexibly along the axial direction of the pressure pipeline. When facing special locations such as the middle of the pipeline, joints, and bends, it is difficult to directly carry out inspection work, resulting in blind spots. Second, traditional devices lack the ability to adapt to different pipelines. For pressure pipelines of different lengths and layouts, it is difficult to adjust the inspection position by adjusting its own structure, resulting in poor versatility. Third, due to the difficulty in flexibly adjusting the inspection position, traditional devices cannot meet the diverse inspection needs of various industrial scenarios. Their use is limited in complex working conditions, and they cannot effectively solve the position adaptation problem in the inspection of special equipment pressure pipelines, resulting in low inspection efficiency and accuracy. Utility Model Content

[0005] Technical problems to be solved The purpose of this utility model is to provide a special equipment pressure pipeline quality inspection device to solve the problem that the existing special equipment pressure pipeline quality inspection devices mentioned in the background art have certain limitations when carrying out inspection operations.

[0008] Furthermore, an electric push rod is fixedly installed on one side inside the fixed groove, and a push rod is fixedly connected to the transmission end of the electric push rod. A movable block is fixedly connected to the end of the push rod away from the electric push rod.

[0009] Furthermore, a movable gantry frame is fixedly connected to the upper surface of the movable block, and a slider is fixedly connected to the bottom end of the movable gantry frame away from the movable block.

[0012] Furthermore, a force-applying plate is fixedly connected to the end of the adjusting rod away from the hydraulic cylinder, and a pressure sensor is fixedly connected to the bottom end of the force-applying plate, with the pressure plate located at the bottom end of the pressure sensor.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1.

This drives a moving block to achieve stable and high-precision horizontal displacement within the installation slot. Consequently, the core inspection components, such as the pressure plate and hydraulic cylinder connected to it, can move flexibly along the axial direction of the pressure pipeline. Whether it is the middle of the pipeline, the joint, or the bend, it can easily reach and carry out inspection work. This freely adjustable inspection position design breaks the limitations of the inspection range of traditional devices and can adapt to the inspection needs of pressure pipelines of different lengths and layouts. It greatly improves the versatility and applicability of the device in various industrial scenarios and effectively solves the problem of position adaptation in the inspection process of special equipment pressure pipelines. 2. This special equipment pressure pipeline quality inspection device, through the cooperation of the arc-shaped positioning cavity, the fixed gantry and the movable gantry, can stably position the pressure pipeline. The arc-shaped positioning cavity can adapt to the arc-shaped contour of the pipeline. The first electric push rod pushes the movable gantry to slide on the slide groove, forming an encircling shape with the fixed gantry. Then, the second electric push rod drives the positioning plate to clamp and fix the pipeline, effectively preventing the pipeline from shifting during the inspection process and ensuring the stability and accuracy of the inspection. 3. This special equipment pressure pipeline quality inspection device monitors the pressure applied to the pressure pipeline by the pressure sensor in real time and feeds the pressure data back to the control system to achieve precise pressure control and avoid the impact of excessive or insufficient pressure on the test results. In addition, the automated operation of multiple electric push rods and motors reduces manual intervention, improves inspection efficiency, reduces the labor intensity of operators, and also ensures the standardization and consistency of the inspection process.

The moving block 6 is slidably connected to the mounting groove 3. A pressure plate 7 is provided below the moving block 6.

[0018] After the pipeline is fixed, if the detection position needs to be adjusted, start the motor 4 in the mounting groove 3. The motor 4 drives the lead screw 5 to rotate. Since the lead screw 5 is connected to the moving block 6 by a thread and the moving block 6 is slidably connected to the mounting groove 3, the rotation of the lead screw 5 will drive the moving block 6 to slide horizontally in the mounting groove 3. This will cause the pressure plate 7, hydraulic cylinder 20, adjusting rod 21, force plate 22 and pressure sensor 23 below the moving block 6 to move axially along the pressure pipeline to align with the part to be detected.

[0019] An arc-shaped positioning cavity 8 is fixedly installed in the middle of the upper surface of the workbench 1. A fixed gantry 9 is installed on one side of the upper surface of the workbench 1 above the arc-shaped positioning cavity 8. A fixed groove 10 is fixedly installed on one side of the upper surface of the workbench 1. An electric push rod 11 is fixedly installed inside one side of the fixed groove 10. A push rod 12 is fixedly connected to the transmission end of the electric push rod 11. A movable block 13 is fixedly connected to the end of the push rod 12 away from the electric push rod 11. A movable gantry 14 is fixedly connected to the upper surface of the movable block 13. A slider 15 is fixedly connected to the bottom end of the movable gantry 14 away from the movable block 13. The upper surface of the workbench 1 is away from the fixed groove 10. A slide groove 16 is fixedly provided on one side, and the slider 15 is slidably connected to the slide groove 16. The fixed gantry 9 and the movable gantry 14 are both provided with two electric push rods 17 on both sides. The transmission end of the electric push rod 17 is fixedly connected to the push rod 18. The end of the push rod 18 away from the electric push rod 17 is fixedly connected to the positioning plate 19. The bottom end of the moving block 6 is fixedly connected to the hydraulic cylinder 20. The transmission end of the bottom end of the hydraulic cylinder 20 is fixedly connected to the adjusting rod 21. The end of the adjusting rod 21 away from the hydraulic cylinder 20 is fixedly connected to the force plate 22. The bottom end of the force plate 22 is fixedly connected to the pressure sensor 23. The pressure plate 7 is located at the bottom end of the pressure sensor 23.

[0020] When using this special equipment pressure pipeline quality inspection device, firstly, the pressure pipeline is placed in the arc-shaped positioning cavity 8 of the workbench 1. The arc-shaped positioning cavity 8 matches the arc-shaped contour of the pipeline, which can initially position the pipeline. Next, the first electric push rod 11 in the fixed groove 10 is activated. The first electric push rod 11 pushes the movable block 13 through the first push rod 12. The movable block 13 drives the movable gantry 14 to slide along the slide groove 16, realizing the adjustment of the position of the movable gantry 14 until it surrounds the pressure pipeline. Subsequently, the second electric push rods 17 on both sides inside the fixed gantry 9 and the movable gantry 14 are activated. The second electric push rod 17 pushes the second push rod 12. 8. Move the positioning plate 19 towards the pipeline and clamp the pipeline to achieve stable fixation of the pressure pipeline. After the detection component moves to the appropriate position, start the hydraulic cylinder 20. The hydraulic cylinder 20 pushes the force plate 22 downward through the adjusting rod 21. The force plate 22 drives the pressure plate 7 to apply pressure to the pressure pipeline. During this process, the pressure sensor 23 at the bottom of the force plate 22 monitors the applied pressure in real time and feeds the pressure data back to the control system (not shown in the figure). The operator can adjust the extension and retraction of the hydraulic cylinder 20 through the control system according to the detection requirements, so as to accurately control the pressure applied to the pressure pipeline to complete the corresponding quality detection work.

[0021] Working Principle: When using this special equipment pressure pipeline quality inspection device, the pressure pipeline is first placed in the arc-shaped positioning cavity 8 of the workbench 1. The arc-shaped positioning cavity 8 matches the arc-shaped contour of the pipeline, which can initially position the pipeline. Next, the first electric push rod 11 in the fixed groove 10 is activated. The first electric push rod 11 pushes the movable block 13 through the first push rod 12. The movable block 13 drives the movable gantry 14 to slide along the slide groove 16, realizing the adjustment of the position of the movable gantry 14 until it surrounds the pressure pipeline. Subsequently, the second electric push rod 17 on both sides inside the fixed gantry 9 and the movable gantry 14 is activated. The second electric push rod 17 pushes the second push rod 18, causing the positioning plate 19 to move towards the pipeline and clamp the pipeline, thereby realizing the stable fixation of the pressure pipeline. After the pipeline is fixed, if it is necessary to adjust the inspection position, the motor 4 in the installation groove 3 is activated. The motor 4 drives the lead screw 5 to rotate. The lead screw 5 and the moving block 6 are connected by threads, and the moving block 6 is slidably connected to the mounting groove 3. The rotation of the lead screw 5 will drive the moving block 6 to slide horizontally in the mounting groove 3, thereby causing the pressure plate 7, hydraulic cylinder 20, adjusting rod 21, force plate 22 and pressure sensor 23 below the moving block 6 to move axially along the pressure pipeline to align with the part to be tested. When the testing part moves to the appropriate position, the hydraulic cylinder 20 is activated. The hydraulic cylinder 20 pushes the force plate 22 downward through the adjusting rod 21. The force plate 22 drives the pressure plate 7 to apply pressure to the pressure pipeline. During this process, the pressure sensor 23 at the bottom of the force plate 22 monitors the applied pressure in real time and feeds the pressure data back to the control system (not shown in the figure). The operator can adjust the extension and retraction of the hydraulic cylinder 20 through the control system according to the testing requirements, thereby accurately controlling the pressure applied to the pressure pipeline to complete the corresponding quality testing work.
