Description

Technical Field

[0001] This utility model belongs to the field of pipeline deformation testing technology, and specifically relates to a pipeline deformation testing device. Background Technology

[0002] In the research, development, production, and quality inspection of fiberglass pipes, deformation testing is a crucial method for evaluating their performance. Currently, existing technologies typically provide the required force by applying counterweights to the pipes. When the test demands a large force, a significant amount of counterweight is required, leading to cumbersome operation and requiring considerable time and effort from staff to move and install the counterweights, resulting in extremely low testing efficiency. Furthermore, repeated handling poses safety hazards due to improper operation. In addition, since fiberglass pipes are often used in specific chemical environments and require immersion in acid and alkali solutions for testing, this places extremely high demands on the corrosion resistance of the testing equipment's structural components. Meeting these requirements often necessitates the use of expensive corrosion-resistant materials or complex and costly anti-corrosion treatments on ordinary materials, significantly increasing manufacturing costs. Therefore, a pipe deformation testing device is urgently needed to address these issues. Utility Model Content

[0003] In view of the problems mentioned above in the background technology, the purpose of this utility model is to provide a pipeline deformation testing device.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] A pipeline deformation testing device includes a frame, a support plate installed on one side of the top of the frame, an acid / alkali solution tank installed on the support plate, a pad installed at the bottom inside the acid / alkali solution tank, support columns installed at the four corners of the support plate, a top plate installed on the top of the support columns, a servo motor installed on the top plate, a screw jack connected to the power output end of the servo motor, a force sensor connected to the power output end of the screw jack, a crossbeam locked to the bottom of the force sensor, side plates installed on both sides of the crossbeam, guide sleeves installed on the front and rear sides of the side plates, the guide sleeves slidably mounted on the support columns, and an extended pressure head installed at the bottom of the crossbeam.

[0006] Furthermore, displacement sensors are installed on both sides of the top plate, and the input ends of the displacement sensors are connected to locking blocks, which are mounted on the side plates. This structural design improves the accuracy of the detection data by enabling simultaneous detection through the displacement sensors on both sides.

[0007] Furthermore, an electrical control box is mounted on the other side of the top of the frame, a support frame is mounted on top of the electrical control box, and a touch screen is mounted on top of the support frame. The touch screen is connected to the servo motor, the screw jack, the force sensor, and the displacement sensor. This structural design facilitates the operation and control of the electrical components.

[0008] Furthermore, the extended pressure head includes an extension frame installed at the bottom of the crossbeam, with the pressure head mounted at the bottom of the extension frame, and the outer side of the pressure head is coated with rubber. This structural design improves the corrosion resistance of the pressure head.

[0009] Furthermore, the frame is equipped with adjusting seats on all four sides at its bottom. Each adjusting seat has threaded holes at its bottom, and an adjusting screw is installed inside each threaded hole. The bottom of each adjusting screw is fitted with an anti-slip foot. This structural design facilitates anti-slip support for the frame and also allows for leveling of the frame by rotating the adjusting screw.

[0010] The beneficial effects of this utility model are as follows: This utility model adopts a servo motor-driven screw jack to replace the traditional counterweight loading method, which greatly simplifies the loading process, reduces the labor intensity of operators, and significantly improves the test efficiency. At the same time, it realizes precise control and monitoring of the loading force, ensuring the accuracy and reliability of the test data. In addition, an extended pressure head is set up so that only the pressure head is in the acid or alkali solution during the test. The pressure head is also coated with rubber to improve corrosion resistance, while preventing other parts from contacting the acid or alkali solution, avoiding corrosion, reducing the use of expensive corrosion-resistant materials, and lowering the manufacturing cost of the equipment.

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1, such as Figure 1 and Figure 2 As shown, a pipeline deformation testing device includes a support plate 2 installed on one side of the top of the frame 1, an acid / alkali solution tank 3 installed on the support plate 2, a pad block 4 installed at the bottom inside the acid / alkali solution tank 3, support columns 5 installed at the four corners of the support plate 2, a top plate 6 installed on the top of the support columns 5, a servo motor 7 installed on the top plate 6, a screw jack 8 connected to the power output end of the servo motor 7, a force sensor 9 connected to the power output end of the screw jack 8, a crossbeam 10 locked to the bottom of the force sensor 9, side plates 11 installed on both sides of the crossbeam 10, guide sleeves 12 installed on the front and rear sides of the side plates 11, the guide sleeves 12 slidingly mounted on the support columns 5, and an extended pressure head 13 installed at the bottom of the crossbeam 10.

[0018] In this embodiment, during the test, the pipe specimen is first placed on the pad 4 in the acid-alkali solution tank 3, and the acid-alkali solution tank 3 is filled with acid-alkali solution to immerse the pipe specimen. Then, the servo motor 7 is started, driving the screw jack 8. The screw jack 8 drives the force sensor 9, which drives the crossbeam 10. The crossbeam 10 drives the side plates 11 on both sides, and the side plates 11 drive the guide sleeves 12 to move vertically along the support column 5. At the same time, the bottom of the crossbeam 10 pushes the extended pressure head 13 into the acid-alkali solution tank 3, so that the bottom of the extended pressure head 13 presses on the pipe specimen. At this time, the force sensor detects the load size, thus starting the test on the pipe specimen. Under long-term testing (such as testing for several hours, several days, or several years), when pipe deformation occurs, a gap is created between the pipe specimen and the extended pressure head 13. At this time, the servo motor 7 will drive the screw jack 8 to apply the same pressure to the pipe specimen for continuous testing.

[0019] Example 2, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: displacement sensors 14 are installed on the left and right sides of the top plate 6, and the input end of the displacement sensor 14 is connected to a locking block 15, which is installed on the side plate 11.

[0020] In this embodiment, during use, when the side plate 11 drives the guide sleeve 12 to move vertically along the support column 5, it will simultaneously drive the locking block 15. The locking block 15 drives the displacement sensor 14 to move until the extended pressure head 13 presses on the pipe specimen. At this time, the displacement sensor 14 is zeroed. Then, during the test, when the pipe specimen changes and the extended pressure head 13 moves, it can be detected by the displacement sensor 14. The deformation of the specimen can be measured. At the same time, to ensure the accuracy of the deformation, the midpoint value of the two displacement sensors 14 is taken to make the test of the deformation of the specimen more accurate.

[0021] Example 3, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: an electrical control box 16 is installed on the other side of the top of the frame 1, a support frame 17 is installed on the top of the electrical control box 16, a touch screen 18 is installed on the top of the support frame 17, and the touch screen 18 is connected to the servo motor 7, the screw jack 8, the force sensor 9, and the displacement sensor 14.

[0022] In this embodiment, during use, the load size can be set via the touch screen 18, causing the servo motor 7 to drive the screw jack 8, which in turn drives the extended pressure head 13 to apply a constant load to the pipe specimen. The force sensor 9 detects the load size, and the displacement sensor 14 detects the height of the pipe specimen to measure the deformation of the specimen. At the same time, the components in the electrical control box 16 can also read the displacement sensor 14 values ​​and recording time to determine whether the specimen has failed. Furthermore, the touch screen 18 can also be used to set test parameters and display the test process data records and results.

[0023] Example 4, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: the extended pressure head 13 includes an extension frame 19 installed at the bottom of the crossbeam 10, and a pressure head 20 is installed at the bottom of the extension frame 19. The outer side of the pressure head 20 is coated with rubber.

[0024] In this embodiment, by setting an extended pressure head 13, only the pressure head 20 is in the acid or alkali solution during the test, and the pressure head 20 is coated with rubber to improve corrosion resistance, while preventing other parts from coming into contact with the acid or alkali solution and avoiding corrosion.

[0025] Example 5, as Figure 1 and Figure 2 As shown, this embodiment adds the following structure based on embodiment 1: adjustment seats 21 are installed on the four sides of the bottom of the frame 1, the bottom of the adjustment seat 21 is provided with threaded holes 22, the threaded holes 22 are installed with adjustment screws 23, and the bottom of the adjustment screws 23 is installed with anti-slip feet 24.

[0026] In this embodiment, during use, the adjusting screw 23 can be rotated to move along the threaded hole 22 of the adjusting seat 21, thereby driving the anti-slip foot 24 to adjust its position so that the frame 1 can be kept in a horizontal state for operation.

[0027] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
