Description

Technical Field

[0001] This utility model relates to the field of pressure pipeline pressure testing technology, and in particular to a pressure pipeline pressure testing device. Background Technology

[0002] When testing the pressure of a pressure pipe, a hydraulic device is generally used to press it downwards while continuously increasing the pressure until a crack appears in the pressure pipe. During the pressure pipe test, the pressure pipe needs to be positioned to prevent it from shifting during the test, thereby making the pressure pipe measurement results more accurate.

[0003] When the pressure pipe is positioned, the positioning structure also applies pressure to the outer surface of the pressure pipe. However, when positioning the pressure pipe, if the positioning mechanism is too close to the pressurization point, the pressure of the positioning mechanism will have a greater impact on the pressurization point, which will lead to a larger error in the pressure detection mechanism. At the same time, when most pressure detection mechanisms pressurize, the pressure water pipe may break. However, there is no shield in front of the detection device, which increases the probability of fragments flying and injuring the staff.

[0004] In response to the above situation, we propose a pressure testing device for pressure pipelines. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure testing device for pressure pipelines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressure testing device for a pressure pipeline includes a workbench, a hydraulic cylinder fixedly connected to the top of the workbench, a receiving cavity extending through the inside of the workbench, two sets of upward-facing slots inside the receiving cavity, a bidirectional lead screw rotatably connected to the inner wall of the slots, the bidirectional lead screw having two sets of helical lines in different directions, and clamps threadedly connected to the positions of the different helical lines of the bidirectional lead screw.

[0008] The end faces of the two sets of bidirectional lead screws are respectively fixedly connected to transmission wheels, and the outer surfaces of the two sets of transmission wheels are meshed with transmission belts. The transmission wheels are rotatably connected inside the worktable.

[0009] The workbench is rotatably connected to a rotating handle at one end near the transmission wheel. The bottom end of the rotating handle passes through the workbench and its end face is fixedly connected to the outer surface of the transmission wheel.

[0010] A support pad is slidably connected to the center of the workbench, and an adjusting screw is threadedly connected to the inside of the support pad.

[0011] A limiting plate is fixedly connected to the outer surface of the workbench near the rotating handle. A slider is slidably connected inside the limiting plate, and a transparent plate is fixedly connected to the top of the slider.

[0012] Preferably, the output end of the hydraulic cylinder passes through the workbench and extends into the interior of the receiving cavity. A pressure sensor is installed at the output end of the hydraulic cylinder, and a pressure pad is installed below the pressure sensor. A pressure detection computer is provided on one side of the workbench, and the pressure detection computer is electrically connected to the pressure sensor.

[0013] Preferably, the workbench is provided with a storage cavity below the receiving cavity, and the inner wall of the storage cavity is rotatably connected to a storage cabinet door.

[0025] Referring to Figures 1-4, a pressure testing device for a pressure pipeline includes a workbench 1. A hydraulic cylinder 3 is fixedly connected to the top of the workbench 1. The output end of the hydraulic cylinder 3 passes through the workbench 1 and extends into the interior of the receiving cavity 2. A pressure sensor 23 is installed at the output end of the hydraulic cylinder 3. A pressure pad 4 is installed below the pressure sensor 23. A pressure detection computer 22 is provided on one side of the workbench 1. The pressure detection computer 22 is electrically connected to the pressure sensor 23. A storage cavity 21 is opened below the receiving cavity 2 on the workbench 1. A storage cabinet door 5 is rotatably connected to the inner wall of the storage cavity 21. A control console 22 is fixedly connected to the outer surface of the workbench 1. Pressing down the hydraulic cylinder 3 will apply pressure to the pressure pipe.

[0026] The workbench 1 has a through-hole cavity 2, and inside the cavity 2 are two sets of upward-facing slots 6. The inner wall of the slots 6 is rotatably connected to a bidirectional lead screw 7, which has two sets of helical lines in different directions. The positions of the different helical lines of the bidirectional lead screw 7 are threadedly connected to clamps 8. The end faces of the two sets of bidirectional lead screws 7 are respectively fixedly connected to transmission wheels 9, and the outer surfaces of the two sets of transmission wheels 9 are meshed with transmission belts 10. The transmission wheels 9 are rotatably connected inside the workbench 1. A rotating handle 11 is rotatably connected inside the workbench 1 near the transmission wheel 9. The bottom end of the rotating handle 11 passes through the workbench 1 and its end face is fixedly connected to the outer surface of the transmission wheel 9. A support pad 12 is slidably connected at the center of the workbench 1. An adjusting screw 13 is threadedly connected inside the support pad 12. The adjusting screw 13 passes through the workbench 1 and extends into the storage cavity 21. The adjusting screw 13 is rotatably connected inside the workbench 1.

[0027] A limiting plate 18 is fixedly connected to the outer surface of the workbench 1 near the rotating handle 11. A slider 17 is slidably connected inside the limiting plate 18. A transparent plate 14 is fixedly connected to the top of the slider 17. Two sets of cleaning roller brushes 16 are provided on both sides of the transparent plate 14. The outer surface of the cleaning roller brushes 16 is in contact with the outer surface of the transparent plate 14. Mounting plates 15 are rotatably connected to both ends of the two sets of cleaning roller brushes 16. A sliding rod 19 is fixedly connected to the outer surface of the mounting plate 15 away from the rotating handle 11. A movable handle 20 is fixedly connected to the bottom end of the sliding rod 19. The cleaning roller brushes 16 can clean the transparent plate 14.

[0028] In summary: When testing the pressure tube, the user first opens the storage cabinet door 5 and rotates the adjusting screw 13. The adjusting screw 13 moves the support plate 12 upward, so that the center point of the pressure tube is close to the center point of the clamping plate 8. Then, the user stops rotating the adjusting screw 13 and closes the storage cabinet door 5. The user then places the pressure tube on the support plate 12 and adjusts the position of the pressure tube so that both ends of the pressure tube are between the clamping plates 8. The user then rotates the rotating handle 11, causing the transmission wheel 9 to rotate, which in turn causes the transmission belt 10 to rotate and drive another set of transmission wheels 9 to rotate. This causes the two sets of bidirectional screws 7 to rotate, which in turn causes the clamping plate 8 to move towards the pressure tube, thus positioning the pressure tube. Finally, the user activates the hydraulic cylinder 3, causing the pressure pad 4 at the output end of the hydraulic cylinder 3 to press down on the surface of the pressure tube, achieving the purpose of testing the surface pressure of the pressure tube.

[0029] During testing, the user holds the transparent plate 14 and slides the slider 17 against the inner wall of the limiting plate 18, so that the transparent plate 14 completely covers the front of the workbench 1. When the user observes the test situation from the outside of the transparent plate 14, the user can hold the moving handle 20 and move it up and down, so that the cleaning roller brush 16 rolls on the outer surface of the transparent plate 14, thereby achieving the purpose of cleaning the transparent plate 14, making the surface of the transparent plate 14 clearer, and allowing the user to see the test situation more clearly.
