Description

Technical Field

[0001] This utility model relates to the field of pipeline testing technology, and in particular to a device for testing the tensile strength of high-temperature pipeline materials. Background Technology

[0002] High-temperature pipelines are frequently used in various fields such as chemical engineering, environmental protection, and new energy, especially in industries like petrochemicals, thermal power plants, and shipping. The performance of high-temperature pipeline materials directly affects the safety of personnel around the pipeline, maintenance cycles, and repair costs. The materials required for high-temperature pipelines not only need to have excellent cooling and insulation properties, but also must meet specific requirements for adhesion strength and tensile strength under different pipe types and orientations. Therefore, tensile strength testing equipment is necessary for testing the tensile strength of high-temperature pipelines.

[0003] Patent CN216559990U discloses a clamp for tensile testing of fiberglass pipes. Electric push rods are installed at the bottom of two fixed pipes. The telescopic ends of the two electric push rods extending into the fixed grooves are equipped with arc-shaped frames. The fiberglass pipe to be fixed is inserted into the fixed groove inside the fixed pipe. The electric push rods drive the arc-shaped frames to move, so that the arc-shaped frames abut against the fiberglass pipe.

[0004] The shortcomings of the aforementioned disclosed solution are as follows: When the arc-shaped frame is pressed against the pipe by an electric actuator, the contact between the fiberglass pipe and the fixed pipe is a line contact. Furthermore, due to the uniform curvature of the arc-shaped frame, when the pipe and the arc-shaped frame are not sized correctly, the contact between them is also a line contact. This results in two lines of contact between the fixed pipe and the arc-shaped frame, making the pipe prone to detaching from the fixed pipe when stretched, failing to effectively limit the pipe's movement, and reducing safety during pipe testing. Additionally, this solution is not suitable for pipes of various diameters. Utility Model Content

[0030] The base has a slot on one side, the drive structure is at least partially disposed in the slot and connected to the inner wall of the slot, and one end of the moving structure is disposed in the slot and slidably connected to the drive structure.

[0031] The movable structure includes a movable plate, one end of which is slidably connected to the driving structure, and the other end of which is provided with and fixedly connected to the fixing component. The fixing structure includes a fixing plate, one end of which is fixedly connected to the base, and the other end of which is provided with and fixedly connected to the fixing component.

[0032] The fixing assembly includes a fixing sleeve, which is a hollow cylinder. The inclined pressing module is fixed to the fixing sleeve and includes a connecting seat and a pressure rod.

[0035] This utility model provides a high-temperature pipeline material tensile strength testing device. By setting a fixing component, the fixing component includes an inclined pressing module. The inclined pressing module is used to gradually increase the pressing force during stretching. The moving structure and the fixing structure are equipped with the fixing component to fix the pipeline sample. During the stretching process, because the inclined pressing module gradually increases the pressing force on the pipeline sample, it avoids the sample from falling off, thus solving the problem of pipeline samples easily falling off during the stretching process and achieving the beneficial effect of safety and stability.

[0036] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 These are, respectively, a three-dimensional structural view of the high-temperature pipe material tensile strength testing device provided in this utility model embodiment, a sectional view of the fixing sleeve of the high-temperature pipe material tensile strength testing device provided in this utility model embodiment, and a three-dimensional structural view of the high-temperature pipe material tensile strength testing device provided in this utility model embodiment. Figure 2 Enlarged view of point A in the middle.

[0037] Specifically, in this embodiment, as Figure 1As shown in the figure, a high-temperature pipe material tensile strength testing device provided by this utility model includes a base 1. The base 1 is provided with a slot, which is located in the middle of the base 1. The cross-section of the slot can be rectangular, square, or irregular. In this embodiment, the cross-section of the slot is preferably rectangular to facilitate fixing the moving structure and to allow the moving structure to move a wider range. The slot not only reduces the weight and facilitates use, but also makes it easy to fix the drive structure and the moving structure, reducing the cost of additional fasteners and reducing the overall required height.

[0038] In this embodiment, as Figure 1 As shown, the high-temperature pipeline material tensile strength testing device further includes a movable structure and a fixed structure. The movable structure is located on one side of the base 1 and can slide relative to the base 1. The fixed structure is located on the same side of the base 1 as the movable structure and is connected to the base 1. The movable structure and the fixed structure are arranged opposite to each other. Ideally, the horizontal center line of the movable structure coincides with the horizontal center line of the fixed structure. In this embodiment, the movable structure includes a movable plate 7, one end of which is located in the slot and can slide relative to the slot. The fixed structure includes a fixed plate 8, one end of which is fixedly connected to the base 1. The cross-sectional shapes of the fixed plate 8 and the movable plate 7 can be the same or different, and no specific limitation is made. When performing a tensile test on a pipeline sample, one end of the pipeline sample is fixedly connected to the movable structure, and the other end is fixedly connected to the fixed structure. Then, moving the movable structure allows for the tensile test of the pipeline sample.

[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the high-temperature pipe material tensile strength testing device also includes a fixing component. The fixing component and the moving structure are located on the same side of the base 1. The fixing component includes an inclined pressing module, which is used to increase the pressing force during tensioning. The moving structure and / or the fixing structure are provided with the fixing component. Specifically, the moving plate 7 has a fixing component at the end away from the groove and is fixedly connected to the moving plate 7; or the fixing plate 8 has a fixing component at the end away from the base 1 and is fixedly connected to the fixing plate 8; or both the moving plate 7 and the fixing plate 8 are provided with fixing components and are fixedly connected. Preferably, the moving plate 7 and the fixing plate 8 are respectively provided with fixing components and are fixedly connected. When performing a tensile test on the pipe sample, one end of the pipe sample is fixedly connected to the fixing component of the fixing plate 8, and the other end is fixedly connected to the fixing component of the moving plate 7. During the tensioning process, as the moving plate 7 moves, the inclined pressing module gradually increases the pressing force on the pipe sample, making the pipe sample more stable and less likely to fall off during the tensioning process.

[0040] For details, please refer to Figure 2 and Figure 3 The fixing component includes a fixing sleeve 9, which is a hollow cylinder. The inclined pressing module is fixed to the fixing sleeve 9. The inclined pressing module includes a connecting seat 11 and a pressing rod 12. The connecting seat 11 is located at the end of the fixing sleeve 9 and is fixedly connected to the end of the fixing sleeve 9. The pressing rod 12 is hinged to the bottom end of the connecting seat 11 and is inclined. The pressing rod 12 is used for fixed pressing. A pressing head 1 is provided at the end of the pressing rod 12 away from the connecting seat 11. 3. The surface of the pressing head 13 is provided with anti-slip grooves, and the opening direction of the anti-slip grooves is perpendicular to the axial direction of the fixed sleeve 9. In addition, an elastic element is fixedly provided between the pressing rod 12 and the fixed sleeve 9. One end of the elastic element is fixedly connected to the pressing rod 12, and the other end is fixedly connected to the inner wall of the fixed sleeve 9. Preferably, the elastic element is a spring 14. The tilting pressing module includes an adjusting pressure column 10. One end of the adjusting pressure column 10 passes through the fixed sleeve 9 and cooperates with the pressing rod 12.

[0041] In this embodiment, specifically, please refer to... Figure 1 , Figure 2 and Figure 3Multiple connecting seats 11 are evenly distributed on one end of the fixed sleeve 9. Ideally, there are three connecting seats 11. A pressure rod 12 is hinged to the bottom end of each connecting seat 11. The pressure rod 12 is located inside the fixed sleeve 9 and is inclined. A pressing head 13 is hinged to the other end of the pressure rod 12. Because the pressure rod 12 is inclined, when the pressure rod 12 drives the pressing head 13 to press the pipe sample, the pressing force of the pressure rod 12 on the pipe sample gradually increases during the stretching process. This results in greater pressure from the pressing head 13 on the pipe sample, and consequently, greater friction between the pipe sample and the pressing head 13, making the pipe sample less likely to fall off and improving the safety of the test. Furthermore, an anti-slip groove is provided on the lower surface of the pressing head 13, with the groove's direction perpendicular to the axial direction of the fixed sleeve 9, further increasing the friction between the pressing head 13 and the pipe sample.

[0042] In addition, in this embodiment, the fixing sleeve 9 is provided with a through hole corresponding to the position of the pressure rod 12. An adjusting pressure column 10 is threaded into the through hole. The adjusting pressure column 10 is used in conjunction with the pressure rod 12. When fixing the pipe sample, the adjusting pressure column 10 is pressed down against the pressure rod 12, thereby causing the pressure rod 12 to drive the pressing head 13 to press against the pipe sample.

[0043] In this embodiment, please refer to Figure 1 The high-temperature pipeline material tensile strength testing device also includes a driving structure. One end of the driving structure is connected to the moving structure, and the driving structure is used to drive the moving plate 7 to move to achieve tensile testing. The driving structure includes a hydraulic pump 5, a hydraulic rod 6, and a guide rail 2. The hydraulic pump 5 is fixedly connected to the base 1. One end of the hydraulic rod 6 is connected to the hydraulic pump 5, and the other end is connected to the moving plate 7. One end of the guide rail 2 passes through the moving plate 7 and is slidably connected to it, while the other end is fixedly connected to the inner wall of the base 1.

[0044] Ideally, in this embodiment, two guide rails 2 are fixedly installed in the slot of the base 1. The guide rails 2 are located on the side of the hydraulic rod 6. The guide rails 2 are slidably connected to the bottom of the moving plate 7. The hydraulic rod 6 pushes the moving plate 7 to move along the guide rails 2, which increases the stability of the moving plate 7.

[0045] In this embodiment, please refer to Figure 1 A tensile force measurement display 3 is fixedly installed on the upper surface of the base 1. The tensile force measurement display 3 is fixedly connected to the moving plate 7 through the tensile force connecting rod 4. When the moving plate 7 moves, the tensile force is transmitted to the inside of the tensile force measurement display 3 through the tensile force connecting rod 4. When the stretched pipe sample breaks, the measured tensile force value is read through the tensile force measurement display 3 to obtain the result. Alternatively, the tensile force value can be set through the tensile force measurement display 3, and when the pipe sample is stretched to the set tensile force value, it can be observed whether the pipe sample breaks.

[0046] In addition, in this embodiment, a spring 14 is fixedly installed on the pressure rod 12. The other end of the spring 14 is fixedly connected to the inner wall of the fixed sleeve 9. After the tensile test is completed, the adjusting pressure column 10 is moved to the outside of the fixed sleeve 9 so that the adjusting pressure column 10 no longer presses against the pressure rod 12. At this time, the pressure rod 12 returns to its original position under the restoring force of the spring 14, which makes it convenient to take out the pipe sample.

[0047] The working principle of the high-temperature pipeline material tensile strength testing device provided by this utility model is as follows: Place both ends of the pipeline sample to be measured into the two fixed sleeves 9, and turn the adjusting pressure column 10 to move it into the fixed sleeve 9, thereby pushing the pressure rod 12 to drive the pressing head 13 to move towards the pipeline sample, so that the pressing head 13 presses the pipeline sample, and the spring 14 is stretched.

[0048] Next, the hydraulic pump 5 is started, which drives the hydraulic rod 6 to push the moving plate 7 along the guide rail 2. The moving plate 7 drives the fixed sleeve 9 to stretch the pipe sample. Since the pressure rod 12 is set at an angle, the pressure of the pressing head 13 on the pipe sample gradually increases during the stretching process, and the friction between the pipe sample and the pressing head 13 also gradually increases, making it difficult for the pipe sample to fall out of the fixed sleeve 9.

[0049] In addition, while the moving plate 7 moves, the tension is transmitted to the tension measurement display 3 through the tension connecting rod 4. When the pipe sample breaks, the hydraulic rod 6 stops pushing the moving plate 7 to move, and the tension value is read out through the tension measurement display 3.

[0050] This utility model provides a high-temperature pipe material tensile strength testing device. A movable structure, a fixed structure, and a driving structure are respectively arranged on a base 1. The movable structure is located on one side of the base 1 and can slide relative to the base 1. The fixed structure is located on the same side of the base 1 as the movable structure and is connected to the base 1. The driving structure pushes the movable structure to move, achieving tensile testing. In addition, a fixing component is provided, including an inclined pressing module. The inclined pressing module gradually increases the pressing force during tensile testing. The movable structure and the fixed structure are equipped with the fixing component to fix the pipe sample. During the tensile process, because the inclined pressing module gradually increases the pressing force on the pipe sample, it prevents the sample from falling off. This ensures that the pipe sample is not easily detached from the fixing sleeve 9 during tensile testing, resulting in good fixing effect and improved work safety.
