[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] like Figures 1-10 As shown;

[0033] To make the non-destructive testing device for pressure vessels used in the production of hazardous chemicals applicable to pressure vessels of different sizes, this non-destructive testing device for pressure vessels used in the production of hazardous chemicals includes a body. Four support legs are fixedly connected to the bottom of the body. A motor is fixedly connected to one side of the body. A first drive shaft is fixedly connected to the output end of the motor. A second drive shaft is rotatably connected to the inside of the body. One end of the second drive shaft passes through the surface of the body. The first drive shaft is connected to the second drive shaft via a belt. A moving device is installed inside the body, and an adjustment device is installed on the top of the moving device.

[0034] The mobile device includes a first hollow box and a second hollow box, which are symmetrically and fixedly connected to the inner bottom wall of the machine body. A lead screw is installed inside the first hollow box, which passes through the inner wall of the first hollow box and extends to the outer side of the first hollow box. The lead screw is rotatably connected to the first hollow box through a bearing. A first sliding box is threadedly connected to the circumferential surface of the lead screw. A turntable is fixedly connected to one end of the lead screw. A pulley is rotatably connected inside the second hollow box. Connecting plates are rotatably connected to both ends of the pulley near the inner wall of the second hollow box. The second sliding box is fixedly connected to the top of the connecting plate.

[0035] In this implementation plan: First, the pressure vessel to be tested is placed on top of the first and second drive shafts. Then, the first and second drive shafts are rotated by a motor, thereby rotating the pressure vessel. When the rotating rod is turned by hand, the rotating rod will drive the turntable and the lead screw to rotate. At this time, the lead screw will drive the first sliding box to move, so that the device can be applied to pressure vessels of different sizes, increasing adaptability.

[0036] Furthermore:

[0037] As shown in Figures 1, 2, and 3:

[0038] Based on the above:

[0039] In an optional embodiment, to fix the turntable in place, a short rod is fixedly connected to the side of the first hollow box near the turntable, a baffle is fixedly connected to the end of the short rod away from the first hollow box, a hollow bottle is slidably connected to the circumferential surface of the short rod, and an insert rod is rotatably connected to the end of the hollow bottle away from the first hollow box.

[0040] In this implementation plan: when the plug rod is pulled by hand, the plug rod will move the hollow bottle, and at this time the hollow bottle will cause the No. 1 spring to contract.

[0041] Furthermore:

[0042] To facilitate the rotation of the turntable, in an optional embodiment, a small hole is provided on the side of the turntable away from the first hollow box, and a rotating roller is rotatably connected to the side of the turntable away from the first hollow box.

[0043] In this implementation plan: workers can move the No. 1 slide box by rotating the turntable, or by shaking the rotating rod.

[0044] Furthermore:

[0045] In order to provide a spring between the hollow bottle and the short rod, in an optional embodiment, a first spring is provided between the baffle and the hollow bottle. One end of the first spring is fixedly connected to the inside of the hollow bottle near the first hollow box, and the other end of the first spring is fixedly connected to the baffle near the first hollow box.

[0046] In this implementation plan: when the insert rod is inserted into the small hole, the insert rod and the hollow bottle will move towards the short rod under the elastic force of the first spring.

[0047] Furthermore:

[0048] In an optional embodiment, the insert rod is matched with the small hole to limit the position of the turntable.

[0049] In this implementation plan: when the insert rod is inserted into the small hole inside the turntable, the turntable will be locked by the insert rod.

[0050] Furthermore:

[0051] In an optional embodiment, an adjustment device is provided on the top of the mobile device;

[0052] The adjustment device includes a first hydraulic rod, which is fixedly connected to the bottom wall inside a first sliding box. A second hydraulic rod is fixedly connected to the bottom wall inside a second sliding box. Slide rails are fixedly connected to the tops of both the first and second hydraulic rods. A detection device is slidably connected to the surface of the slide rails. A second large hole is formed at the end of the detection device away from the motor. A short column is disposed inside the second large hole and slidably connected to the detection device. A baffle is fixedly connected to the circumference of the short column. A square plate is fixedly connected to the end of the short column away from the baffle, and a handle is fixedly connected to the end of the square plate away from the short column.

[0053] Furthermore:

[0054] In an optional embodiment, a second spring is provided between the baffle and the detection device. One end of the second spring is fixedly connected to the end of the baffle near the square plate, and the other end of the second spring is fixedly connected to the side of the detection device near the square plate.

[0055] In this implementation plan: when the handle is released, the handle and the square plate will be driven by the elastic force of the second spring to insert the short column into the first large hole.

[0056] Furthermore:

[0057] In an optional embodiment, a large hole is provided on the side of the slide rail near the square plate, and the short column is slidably connected to the slide rail through the large hole.

[0058] In this implementation scheme: the short column 75 slides through the second large hole 711, and the end of the short column 75 near the slide rail 73 will be inserted into the first large hole 710.

[0059] Working principle: First, place the pressure vessel to be tested on top of drive shaft 4 and drive shaft 5. Then, start motor 3. When motor 3 starts, its output will drive drive shaft 4 to rotate. When drive shaft 4 rotates, it will drive belt 8 to rotate. When belt 8 rotates, it will drive drive shaft 5 to rotate. At this time, drive shafts 4 and 5 will drive the pressure vessel to rotate. Then, by manually cranking the rotating roller 65 or rotating the turntable 64, the pressure vessel will rotate. This will cause the lead screw 62 to rotate. Because the lead screw 62 is threadedly connected to the first slide box 63, when the lead screw 62 rotates, it will cause the first slide box 63 to move. When the first slide box 63 moves, it will cause the first hydraulic rod 71 to move. When the first hydraulic rod 71 moves, it will cause the slide rail 73 to continue moving. When the slide rail 73 moves, it will cause the second hydraulic rod 72 to move. When the second hydraulic rod 72 moves, it will... The second sliding box 613 moves, which in turn moves the connecting plate 614. This movement, in turn, moves the pulley 615 inside the second hollow box 612. The pulley 615 provides support. The position of the testing device 74 is adjusted according to the size of the pressure vessel, allowing it to be used with different pressure vessels. When the testing device 74 is in the appropriate position, the insertion rod 68 is pulled, and the insertion rod 68 will... The hollow bottle 67 is moved, and when the hollow bottle 67 moves, it will cause the first spring 611 to retract, inserting the insertion rod 68 into the small hole 66. After that, the insertion rod 68 is released, and at this time, the insertion rod 68 will move in the opposite direction under the elastic force of the first spring 611. At this time, the turntable 64 will be fixed to prevent the worker from accidentally touching the turntable 64 and causing the position of the detection device 74 to move. When the first drive shaft 4 and the second drive shaft 5 drive the pressure vessel to rotate, the detection device 74 can perform detection on the surface of the pressure vessel.

[0060] After the testing device 74 completes the test at one position, by pulling the handle 79, the handle 79 will move the square plate 78. When the square plate 78 moves, it will move the short column 75. When the short column 75 moves, it will move the baffle 76. When the baffle 76 moves, it will cause the second spring 77 to retract. By moving the handle 79 again, the handle 79 will move the short column 75. When the short column 75 moves to the position of another large hole 710, by releasing the handle 79, the handle 79 and the square plate 78 will, under the elastic force of the second spring 77, drive the short column 75 to insert into the large hole 710, thus completing the position change operation. When a problem is detected, the height of the first hydraulic rod 71 and the second hydraulic rod 72 can be adjusted for detailed testing.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
