[0019] To make the objectives, technical solutions, and advantages of this 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a pipe interface sealing water injection pressure test fixture, including a base plate 1, and vertical plates 2 that can be movably arranged at both ends of the top of the base plate 1. Each vertical plate 2 has a first bearing short pipe 3 and a second bearing short pipe 5 arranged inside. The first bearing short pipe 3 is equipped with an exhaust valve and a pressure gauge 4, and the second bearing short pipe 5 is equipped with a water inlet pipe.

[0021] The first bearing short pipe 3 and the second bearing short pipe 5 are used for water injection, air venting and pressure monitoring during pipeline pressure testing. This is existing technology and will not be described in detail here.

[0022] A support plate 8 is provided on the top of the base plate 1. A horizontal plate 10 is provided on the top of the support plate 8. An arc-shaped support seat 11 is provided on the top of the horizontal plate 10. A placement seat 14 is provided on one side of the base plate 1 and between the two horizontal plates 10. A receiving box 15 is provided on one side of the placement seat 14. A discharge port is opened on the side of the receiving box 15 located on the placement seat 14. A guide plate 16 is rotatably provided at the bottom of the discharge port.

[0023] In this embodiment, the arc-shaped support 11 is used to place the pipe for pressure testing.

[0024] The placement seat 14 is located between two arc-shaped support seats 11, ensuring that the pipes on the placement seat 14 can be removed through the arc-shaped support seats 11.

[0025] The container 15 is used to stack the pipes to be tested. The placement seat 14 is used to place the pipes to be tested on the placement seat 14. The pipes to be tested are moved to the base plate 1 by the arc-shaped support seat 11 and aligned with the first bearing plate short pipe 3 and the second bearing plate short pipe 5 to ensure that there are no errors during processing.

[0026] First, the pipe is placed in the receiving box 15. Then, the pipe inside the receiving box 15 is moved to the outlet by the drive assembly of the receiving box 15. Next, the pipe inside the receiving box 15 is directed to the placement seat 14 by rotating the guide plate 16. Then, the pipe on the placement seat 14 is moved to the middle of the base plate 1 by driving the arc support seat 11. Next, the vertical plate 2 is moved to both ends of the pipe, connecting the first bearing plate short pipe 3 (air vent valve and pressure gauge 4) to the second bearing plate short pipe 5 (water inlet pipe) to complete the sealing of the pressure test interface. Then, the air vent valve is opened, and water is injected into the pipe through the water inlet pipe of the second bearing plate short pipe 5 to remove air. The pressure gauge 4 is observed. When the pressure stabilizes, the air vent valve is closed, and the pressure is gradually increased to the design pressure. The reading of the pressure gauge 4 is continuously monitored to judge the sealing performance of the pipe. If leakage is found, the pressure value is recorded and the pressure test is stopped.

[0027] Furthermore, the upper surface of the base plate 1 is provided with a first electric slide rail 6 at both ends, and a first slider 7 is slidably provided on the surface of the first electric slide rail 6, and each vertical plate 2 is fixedly connected to the surface of each first slider 7.

[0028] In this embodiment, the first electric slide rail 6 is activated, which drives the first slider 7 to slide. The vertical plate 2 moves with the first slider 7, which drives the first bearing short pipe 3 (exhaust valve and pressure gauge 4) and the second bearing short pipe 5 (water inlet pipe) to complete the sealing of the pressure test interface.

[0029] Furthermore, two first hydraulic cylinders 9 are vertically arranged in the middle of the upper surface of the base plate 1, and each of the horizontal plates 10 is fixedly connected to the top of each of the first hydraulic cylinders 9.

[0030] In this embodiment, when the pipe is located on the placement seat 14, the arc-shaped support seat 11 is moved to both ends of the placement seat 14, and then the first hydraulic cylinder 9 is driven to move the arc-shaped support seat 11 upward, thereby moving the pipe on the placement seat 14 to the middle of the base plate 1 for pressure testing.

[0031] Furthermore, each of the horizontal plates 10 is provided with a second electric slide rail 12, and a second slider 13 is slidably provided on the surface of the second electric slide rail 12, and the arc-shaped support seat 11 is fixedly connected to the surface of the second slider 13.

[0032] In this embodiment, when it is necessary to unload the pipe or move it above the base plate 1, the second electric slide rail 12 is controlled to drive the second slider 13 to slide. Since the second slider 13 is fixedly connected to the arc-shaped support seat 11, the arc-shaped support seat 11 is driven to slide along its length direction to both ends of the placement seat 14 or above the unloading area.

[0033] Furthermore, the rear of the receiving box 15 is provided with a through hole corresponding to the discharge port, and a push plate 17 is movably arranged in the through hole. A second hydraulic cylinder 22 is arranged laterally on the rear side of the receiving box 15. One end of the second hydraulic cylinder 22 is fixedly connected to the surface of the push plate 17. Several third hydraulic cylinders 23 are arranged vertically at the bottom of the inner cavity of the receiving box 15, and an arc-shaped feeding plate 24 is fixedly connected to the top of the third hydraulic cylinder 23.

[0034] In this embodiment, the pipes to be tested are stacked horizontally in the receiving box 15. The third hydraulic cylinder 23 is activated to drive the arc-shaped feeding plate 24 to rise, thereby driving the pipes to the discharge port. When the pipes are aligned with the discharge port, the second hydraulic cylinder 22 is activated to push the push plate 17 forward. The push plate 17 pushes the foremost pipe out of the through hole, and the pipes slide down onto the placement seat 14.

[0035] Furthermore, the surface of the receiving box 15 and the two ends of the discharge port are provided with support columns 21, and a rotating shaft 19 is rotatably provided between the two support columns 21. The guide plate 16 is fixedly connected to the surface of the rotating shaft 19. A motor 20 is fixedly connected to the side wall of one of the support columns 21, and the output shaft of the motor 20 is fixedly connected to one end of the rotating shaft 19.

[0036] In this embodiment, after the guide plate 16 rotates down, it is ensured to be flush with one end of the placement seat 14.

[0037] Baffles are provided on both sides of the guide plate 16 to prevent the pipe from deviating when it is left behind.

[0038] When it is necessary to transport the pipe from the container 15 to the placement seat 14, the motor 20 is started to drive the rotating shaft 19 to rotate, thereby driving the guide plate 16 to rotate until it is in contact with one end of the placement seat 14.

[0039] Furthermore, a plurality of fourth hydraulic cylinders 25 are vertically arranged on the other side of the base plate 1, and an arc-shaped receiving plate 18 for assisting in unloading is fixedly connected to the top of the fourth hydraulic cylinders 25.

[0040] In this embodiment, after the pipeline pressure test is completed, it is moved to the other side by the arc-shaped support 11, and then the pipeline on the arc-shaped support 11 is removed by driving the fourth hydraulic cylinder 25, and then the next process can be carried out.

[0041] The working principle and usage process of this utility model are as follows: After the utility model is installed, the pipeline to be pressure tested is horizontally stacked in the receiving box 15. The third hydraulic cylinder 23 is started to drive the arc-shaped feeding plate 24 to rise. The pipeline rises with the arc-shaped feeding plate 24 to the discharge port. Then, the guide plate 16 is rotated to align with the placement seat 14. The second hydraulic cylinder 22 is started to push the push plate 17 to push the pipeline out of the discharge port. The pipeline slides down along the guide plate 16 to the placement seat 14. The first hydraulic cylinder 9 is started to drive the horizontal plate 10 to rise, so that the arc-shaped support seat 11 receives the pipeline on the placement seat 14. The first electric slide rail 6 is started to drive the first slider 7 to slide, which moves the vertical plate 2 to both ends of the pipeline, so that the bearing plate short pipe is connected with the pipeline. The exhaust valve is opened and water is injected into the pipeline through the water inlet pipe of the second disc short pipe 5 to remove air. The pressure gauge 4 is observed. When the pressure is stable, the exhaust valve is closed and the pressure is gradually increased to the design pressure. The reading of the pressure gauge 4 is continuously monitored to judge the sealing performance of the pipeline. If a leak is detected, record the pressure value and stop the pressure test. After the pressure test is completed, start the fourth hydraulic cylinder 25 to drive the arc-shaped receiving plate 18 to rise, and the auxiliary arc-shaped support seat 11 will move the pipeline to the next process.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
