[0032] The outer wall of the threaded rod 16 is provided with symmetrically distributed left-handed threads and right-handed threads, and the outer wall of the threaded rod 16 is threadedly sleeved with symmetrically distributed support seats 19, and a limit rod 18 is fixedly installed above the threaded rod 16 between the two fixing plates 17, and a second motor 15 is fixedly installed on one side of a fixing plate 17, and the driving end of the second motor 15 passes through one side of a fixing plate 17 and extends between the two fixing plates 17 and is fixedly connected to one end of the threaded rod 16, and symmetrically distributed grooves 9 are opened in the groove at the top of the support seat 19;

[0033] A driving wheel 10 is rotatably mounted on the groove 9, and a first motor 11 is fixedly mounted on opposite sides of the two support seats 19, and the driving end of the first motor 11 penetrates the side of the support seat 19 and extends to the inside of the corresponding groove 9 and is fixedly connected to one end of the driving wheel 10. An explosion-proof box 8 is fixedly mounted on the top of the base plate 1, and an explosion-proof door 6 is arranged on the front of the explosion-proof box 8, and an explosion-proof glass is fixedly inlaid on the front of the explosion-proof door 6. Through the setting of the explosion-proof glass, the staff can observe the detection status of the pressure vessel outside the device so as to make corresponding adjustments in time.

[0034] In this example, both sides of the inner wall of the fixed groove 3 are provided with a slide groove 24, and the inside of the two slide grooves 24 are rotatably installed with an adjusting screw rod 25, and the outer wall of the two adjusting screw rods 25 is threaded with an adjusting block 14, and the adjusting block 14 is slidably connected with the slide groove 24, and the two adjusting blocks 14 are respectively fixedly connected to the rear of both sides of the movable plate 4, and a protective box 22 is fixedly installed on the back of the base plate 1, and the rear end of the adjusting screw rod 25 passes through the rear side of the inner wall of the slide groove 24 and extends to the inside of the protective box 22, and a driving mechanism is arranged inside the protective box 22, and a plurality of supporting wheels 5 are fixedly installed at the bottom of the movable plate 4. Through the arrangement of the supporting wheels 5, the supporting wheels 5 are in rolling contact with the ground during the use of the movable plate 4, which improves the stability of the movable plate 4 during the use.

[0035] In this example, the top of the explosion-proof box 8 is fixedly interlaced with an electric telescopic rod 7, the driving end of the electric telescopic rod 7 is fixedly installed with a movable frame 12, and the bottom of the movable frame 12 is provided with symmetrically distributed limiting wheels 13, and the limiting wheels 13 are fixed to the bottom of the movable frame 12 by bolts. It has a limiting effect on the pressure vessel in the detection state and improves the stability during the detection process.

[0036] The driving mechanism in this example includes a worm 20, and the worm 20 is rotatably mounted inside the protection box 22, a worm wheel 21 is fixedly mounted on the rear end outer wall of the two adjusting screws 25, and the worm wheel 21 is meshed with the worm 20, a third motor 23 is fixedly mounted on one side of the protection box 22, and the driving end of the third motor 23 penetrates one side of the protection box 22 and extends to the inside of the protection box 22 and is fixedly connected to one end of the worm 20. The longitudinal movement of the movable plate 4 is achieved by mechanical drive, which is convenient for the staff to take and place the pressure vessel.

[0037] In this example, a plurality of balls 26 are movably mounted on the bottom of the support seat 19, and the balls 26 are in rolling contact with the top of the movable plate 4. The support seat 19 is in contact with the top of the movable plate 4, so that the support seat 19 can support and limit the pressure vessel more stably. At the same time, the rolling contact between the balls 26 and the movable plate 4 reduces the wear of the bottom of the support seat 19 and increases the service life of the support seat 19.

[0038] In this example, a sliding hole matching the limiting rod 18 is provided on one side of the support seat 19, and the support seat 19 is slidably connected to the limiting rod 18 through the sliding hole provided on one side thereof, so that a stable lateral movement effect of the support seat 19 is achieved.

[0039] Working principle: According to Figure 1-5As shown, the electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing public power connection technology is not repeated in the text. When in use, open the explosion-proof door 6 on the front of the explosion-proof box 8, and then adjust the distance between the two support seats 19 according to the height of the pressure vessel, control the second motor 15 to start working, and the driving end of the second motor 15 drives the threaded rod 16 to rotate. Through the threaded transmission of the left-handed thread and the right-handed thread on the threaded rod 16 and the sliding relationship between the support seat 19 and the limit rod 18, the two support seats 19 are simultaneously and stably moved relative to each other or in the opposite direction. After adjusting the position of the support seat 19, the pressure vessel is directly placed horizontally on the grooves at the top of the two support seats 19 and connected with the driving The wheels 10 collide with each other and close the explosion-proof door 6. At the same time, the first motor 11 is controlled to start working. The driving end of the first motor 11 drives the driving wheel 10 to rotate. The friction force generated between the driving wheel 10 and the outer wall of the pressure vessel drives the pressure vessel to rotate, causing the pressure vessel to rotate, so that different areas of the inner wall of the pressure vessel are subjected to the same large water pressure, so as to improve the accuracy of the test results. During the entire detection process, the pressure vessel is located in a closed space formed by the explosion-proof box 8, the explosion-proof door 6, the base plate 1 and the movable plate 4. Even if the pressure vessel explodes due to quality problems during the detection process, the explosion phenomenon will only be limited to this closed space and will not cause harm to the detection personnel around the device, which greatly improves the safety and reliability of the device when in use;

[0040] according to Figure 1-3 As shown, in the process of placing and removing the pressure vessel, the explosion-proof door 6 is in the open state, and the third motor 23 can be controlled to start working first. The driving end of the third motor 23 drives the worm 20 to rotate, and the two worm wheels 21 are rotated synchronously through the meshing of the worm 20 and the worm wheel 21. The rotation of the worm wheel 21 drives the two adjusting screws 25 to rotate. Through the threaded transmission of the adjusting screw 25 and the adjusting block 14, and the sliding relationship between the adjusting block 14 and the slide groove 24, the two adjusting blocks 14 are synchronously moved longitudinally. The movement of the adjusting block 14 drives the movable plate 4 to move, and the support seat 19 moves with the movable plate 4. The movable plate 4 can be moved forward, so that the support seat 19 is moved out from the inside of the explosion-proof box 8 and placed in front of the front of the explosion-proof box 8. In this way, in the process of taking and placing the pressure vessel, the explosion-proof box 8 will not cause obstacles, which improves the usability of the device and provides a more convenient use experience for the operator.

[0041] according to Figure 2 and Figure 4As shown, during the dynamic detection of the pressure vessel, before the pressure vessel rotates, the electric telescopic rod 7 can be controlled to start working, and the driving end of the electric telescopic rod 7 drives the limiting wheel 13 to move vertically through the movable frame 12, so that the limiting wheel 13 contacts the upper side of the outer surface of the pressure vessel, limits the pressure vessel, and makes the contact between the pressure vessel and the driving wheel 10 more stable, thereby ensuring the stable implementation of the water pressure test.
