The two connecting frames 17 are respectively arranged on both sides of the L-shaped movable block 15. A guide rod 18 is installed between the two connecting frames 17. The guide rod 18 movably passes through the movable slot 16. When the L-shaped movable block 15 moves upward as a whole, the guide rod 18 movably passes through the movable slot 16. Under the action of the movable groove 16, the connecting frame 17 and the guide rod 18, the steel frame 4 and the first cylinder 3 near one end of the main frame 2 can be lifted upward, and the steel frame 4 and the first cylinder 3 will rotate around the sleeve 6, and the steel frame 4 and the first cylinder 3 on the other side of the sleeve 6 will move downward. At this time, the valve will be immersed in the detection liquid inside the detection frame 1. A linkage mechanism 27 is connected between the L-shaped movable block 15 and the square plate 20. Under the action of the linkage mechanism 27, the second cylinder 19 can drive the L-shaped movable block 15 to move up and down through the square plate 20 and the linkage mechanism 27.

[0021] Grooves are provided on the surface of the main frame 2 and on both sides of the through groove, and fixed frames 22 are installed inside the main frame 2 and on both sides of the L-shaped movable block 15. The connecting rod mechanism 21 includes two sliders 23, and the two sliders 23 are respectively slidably installed on the surfaces of the two fixed frames 22. The two sliders 23 are respectively connected to the first slide 8 and the second slide 9 through the grooves, and the other end of the slider 23 is installed with a first mounting frame 24, and the two ends of the square plate 20 are installed with a second mounting frame 25. A connecting rod 26 is connected between the first mounting frame 24 and the second mounting frame 25 through a rotating shaft. When the second cylinder 19 drives the square plate 20 to move downward, under the action of the connecting rod 26, the two sliders 23 will move toward the middle of the main frame 2 at the same time, and at this time, the first slide 8 and the second slide 9 will also move toward the middle of the detection frame 1 at the same time.

[0022] A polished rod parallel to the second cylinder 19 is installed inside the main frame 2, and the L-shaped movable block 15 is movably sleeved on the surface of the polished rod. The polished rod is arranged just above the L-shaped movable block 15, and the top of the L-shaped movable block 15 is movably plugged into the surface of the polished rod. The polished rod provides a guide for the L-shaped movable block 15. The linkage mechanism 27 includes a connecting plate 28. A bottom frame 29 is fixedly installed on the surface of the square plate 20. A sliding groove 31 is provided at the bottom of the L-shaped movable block 15. A top frame 30 is slidably installed inside the sliding groove 31. The upper and lower end surfaces of the connecting plate 28 are respectively connected to the top frame 30 and the bottom frame 29 through a rotating shaft. When the second cylinder 19 drives the square plate 20 to move downward, the connecting plate 28 has a pulling effect on the L-shaped movable block 15, and the connecting plate 28 inside the linkage mechanism 27 will The top frame 30 is pushed to slide inside the sliding groove 31. When the top frame 30 slides to one end of the sliding groove 31, the square plate 20 can drive the L-shaped movable block 15 to move downward through the connecting plate 28. Then, when the second cylinder 19 drives the square plate 20 to move upward, since the top frame 30 is slidably installed in the sliding groove 31, during the upward movement of the square plate 20, the connecting plate 28 will push the top frame 30 to slide inside the sliding groove 31. When the top frame 30 slides to the end of the sliding groove 31, the square plate 20 can drag the L-shaped movable block 15 to move upward. By setting the linkage mechanism 27, the square plate 20 can drive the connecting rod mechanism 21 to move, and then control the lifting mechanism 14 to avoid the first slide 8 and the second slide 9 from affecting the clamping mechanism 7.

[0023] An air inlet is provided on the surface of the second clamping head 13, and an air pressure detection device is provided on the side of the detection frame 1. The air inlet is connected to the air pressure detection device through an air pipe to ensure the integrity of the structure. The air pressure detection device can inflate the inside of the valve to be detected through the air pipe and the air inlet.

[0024] Working principle: First, the first cylinder 3 can control the second clamping head 13 to move toward the direction of the first clamping head 12 to clamp the valve to be detected on the surface of the center plate, and then the second cylinder 19 drives the square plate 20 to move upward. At this time, under the action of the connecting rod 26, the two sliders 23 will move to the side of the main frame 2 at the same time. At this time, the first slide 8 and the second slide 9 will also move to the side of the detection frame 1 at the same time. At the same time, the connecting plate 28 inside the linkage mechanism 27 will push the top frame 30 to slide inside the sliding groove 31. When the top frame 30 slides to the end of the sliding groove 31, the square plate 20 can drag the L-shaped movable block 15 to move upward Then, under the action of the movable groove 16, the connecting frame 17 and the guide rod 18, the steel frame 4 and the first cylinder 3 near one end of the main frame 2 can be lifted upward, and the steel frame 4 and the first cylinder 3 will rotate around the sleeve 6, and the steel frame 4 and the first cylinder 3 on the other side of the sleeve 6 will move downward. At this time, the valve will be immersed in the detection liquid inside the detection frame 1. The subsequent air pressure detection device can inflate the inside of the valve to be detected through the air pipe and the air inlet hole. The staff observes the valve inside the detection liquid and records the status of the valve. In the next step, the staff will place the next valve to be detected on the surface of the center plate, and the second cylinder 1 9 drives the square plate 20 to move downward. Under the action of the connecting rod 26, the two sliders 23 will move to the middle of the main frame 2 at the same time. At this time, the first slide 8 and the second slide 9 will also move to the middle of the detection frame 1 at the same time. At the same time, the connecting plate 28 has a pulling effect on the L-shaped movable block 15. The connecting plate 28 inside the linkage mechanism 27 will push the top frame 30 to slide inside the sliding groove 31. When the top frame 30 slides to the other end of the sliding groove 31, the square plate 20 can drive the L-shaped movable block 15 to move downward through the connecting plate 28. Subsequently, under the action of the lifting mechanism 14, the sleeve 6 rotates in the middle of the fixed rod 5, so that the first cylinder 3. The steel frame 4 and the clamping mechanism 7 are parallel to the detection liquid, and then the first cylinder 3 drives the second clamping head 13 to recover, and the detected valve will fall on the surface of the center plate. After the first cylinder 3 positions the valve to be detected, during the process of the first slide 8 and the second slide 9 to the side of the detection frame 1, the valve to be detected will squeeze and push the valve after detection, so that the valve after detection will fall to the surface of the first slide 8, and the second slide 9 moves to the middle of the detection frame 1, and the center plate can move between the first clamping head 12 and the second clamping head 13. At this time, the first cylinder 3 can control the second clamping head 13 to clamp the next valve to be detected.
