Adjustable wind shield for tank angle weld penetration testing

Abstract

This utility model discloses an adjustable windproof fixture for penetrant testing of fillet welds in tank bodies. It includes a fixed box with an adjustment mechanism below it. The adjustment mechanism includes at least two fixed columns positioned below the fixed box. A rotating plate is rotatably connected to the circumferential side of each fixed column, and a rotating plate is rotatably connected to the circumferential side of each fixed column, intersecting and aligned with the rotating plate. One side of the rotating plate is slidably connected to one side of the rotating plate. This utility model uses the rotating plate to move the device to the fillet weld on the outer wall of the tank. Rotating the screw rod causes the square column to move, which in turn causes the screw rod to rotate. The screw rod then moves a moving plate, which in turn moves a toothed plate. The toothed plate rotates a rotating shaft, which in turn rotates the two fixed columns in opposite directions. The fixed columns then rotate the rotating plates, causing them to fit against the outer circumferential wall of the tank.

Description

Technical Field

[0001] This utility model relates to the technical field of penetrant testing windproof devices, and in particular to an adjustable windproof tooling for penetrant testing of tank fillet welds. Background Technology

[0002] Penetrant testing, also known as penetrant inspection, is a non-destructive testing method based on the principle of capillary action to inspect surface opening defects.

[0003] The penetrant testing process involves a series of steps, including surface preparation and pre-cleaning, application of penetrant, removal of excess penetrant, drying, application of developer, observation and evaluation, cleaning, and retesting. In particular, when spraying the developer, there are specific requirements regarding the distance between the nozzle and the surface being tested. In outdoor or open environments, where wind speeds are high, the developer may not be evenly applied to the fillet welds on the outer wall of the tank, thus affecting the effectiveness of the penetrant testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable windproof tooling for penetrating tank fillet welds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable windproof fixture for penetrant testing of fillet welds in tanks includes a fixed box with an adjustment mechanism below it. The adjustment mechanism includes at least two fixed columns disposed below the fixed box. A rotating plate is rotatably connected to the circumferential side of each fixed column, and a rotating plate is rotatably connected to the circumferential side of each fixed column, which is staggered and aligned with the rotating plate. One side of the rotating plate is slidably connected to one side of the rotating plate.

[0007] Preferably, a fixing block aligned with the rotating plate 1 is fixedly connected to one side of the rotating plate 2, a spring is fixedly connected between the top of the fixing block and the bottom of the rotating plate 1, a shielding strip 1 is fixedly connected between one side of the two rotating plates 1, and a shielding strip 2 aligned with the shielding strip 1 is fixedly connected to the circumferential side of the rotating plate 2, and the circumferential side of the shielding strip 1 is slidably connected to the circumferential side of the shielding strip 2.

[0008] Preferably, a rotating shaft aligned with the fixed box is fixedly connected to the circumferential side of the fixed column, and the other end of the rotating shaft extends into the interior of the fixed box. A lead screw is rotatably connected between the two inner walls of the fixed box, and at least two movable plates aligned with the rotating shaft are threadedly connected to the circumferential side of the lead screw.

[0009] Preferably, the bottom of the movable plate is fixedly connected to a toothed plate aligned with the rotating shaft, the side of the toothed plate is meshed with the circumferential side of the rotating shaft, a square groove is provided between the two ends of the lead screw, a square column is slidably connected between the top inner wall and the bottom inner wall of the square groove, and a lead screw is rotatably connected to both sides of the square column, the other end of the lead screw extends to the outside of the fixed box, and the circumferential side of the lead screw is threaded to the inside of one side of the fixed box.

[0010] Preferably, a connecting post is fixedly connected to the inside of one side of the fixing post, a fixing frame is connected to the other end of the connecting post by a ratchet, a fixing plate is detachably connected to the side of the fixing frame, and an opening and closing ring is fixedly connected to the other side of the fixing plate.

[0011] Preferably, a semi-circular ring is fixedly connected to the circumferential side of the opening and closing ring, a semi-circular plate aligned with the opening and closing ring is fixedly connected to the bottom inner wall of the fixing frame, and a tank is detachably connected to the bottom of the fixing frame.

[0012] Preferably, an opening is provided between the inner and outer walls of the top of the fixing frame, a motor aligned with the opening is fixedly connected to one side of the fixing frame, a rotating shaft is fixedly connected to the output shaft of the motor, and a cam aligned with the opening is fixedly connected to the circumferential side of the rotating shaft.

[0013] Compared with the prior art, this utility model provides an adjustable windproof tooling for penetrant testing of tank fillet welds, which has the following beneficial effects:

[0014] The device is moved to the fillet weld on the outer wall of the tank by rotating plate one. Rotating screw two moves the square column, which in turn moves screw one, which in turn moves the moving plate, which in turn moves the toothed plate, which in turn rotates the rotating shaft. The rotating shaft then rotates the two fixed columns in opposite directions, causing rotating plates one and two to rotate. This allows rotating plates one and two to fit against the outer circumference of the tank, facilitating adjustment based on the tank's curvature and improving the device's applicability. Simultaneously, springs push rotating plates one and two to rotate, which in turn rotate shielding strips one and two, respectively. This ensures that rotating plates one and two, along with shielding strips one and two, completely surround the fillet weld area of ​​the tank to be coated, further enhancing the device's performance. To prevent the penetrant or developer from being blown away by external wind during spraying, which could prevent it from fully covering the fillet weld on the outer wall of the tank and affect the penetration detection effect of the device on the fillet weld, the device should be moved to rotate the first rotating plate and the first shielding belt to open the opening and closing ring and the semi-circular ring. The spray can should be placed in the fixed frame and the opening and closing plate and the semi-circular ring should be reset. The fixed frame should be rotated so that the spray can and the fillet weld of the tank form a certain angle. This allows the device to adjust the angle between the spray can and the fillet weld according to the penetration detection needs, improving the applicability of the device. The motor should be started so that the motor drives the rotating shaft to rotate. The rotating shaft drives the cam to rotate. The cam squeezes the spray can and sprays the penetrant or developer onto the fillet weld of the tank. The device should be moved so that the device drives the spray can to spray the penetrant or developer along the fillet weld of the outer wall of the tank. Attached Figure Description

A rotating plate 4, which is staggered and aligned with the rotating plate 3, is rotatably connected to the circumferential side of the fixed column 1. One side of the rotating plate 4 is slidably connected to one side of the rotating plate 3.

[0021] In this utility model, a fixing block 11 aligned with a rotating plate 3 is fixedly connected to one side of the rotating plate 4. A spring 10 is fixedly connected between the top of the fixing block 11 and the bottom of the rotating plate 3. A shielding strip 5 is fixedly connected between one side of the two rotating plates 3. A shielding strip 9 aligned with the shielding strip 5 is fixedly connected to the circumferential side of the rotating plate 4. The circumferential side of the shielding strip 5 is slidably connected to the circumferential side of the shielding strip 9.

[0022] The circumferential side of the fixed column 1 is fixedly connected to a rotating shaft 19 aligned with the fixed box 8. The other end of the rotating shaft 19 extends into the interior of the fixed box 8. A lead screw 7 is rotatably connected between the two inner walls of the fixed box 8. At least two movable plates 21 aligned with the rotating shaft 19 are threadedly connected to the circumferential side of the lead screw 7.

[0023] The bottom of the movable plate 21 is fixedly connected to a toothed plate 20 aligned with the rotating shaft 19. The side of the toothed plate 20 is meshed with the circumferential side of the rotating shaft 19. A square groove is provided between the two ends of the lead screw 7. A square column 6 is slidably connected between the top inner wall and the bottom inner wall of the square groove. Both sides of the square column 6 are rotatably connected to a lead screw 22. The other end of the lead screw 22 extends to the outside of the fixed box 8. The circumferential side of the lead screw 22 is threadedly connected to the inside of one side of the fixed box 8.

[0024] A connecting post 2 is fixedly connected to one side of the fixed post 1. A ratchet is connected to a fixing frame 16 at the other end of the connecting post 2. A fixing plate 12 is detachably connected to the side of the fixing frame 16. An opening and closing ring 13 is fixedly connected to the other side of the fixing plate 12.

[0025] A semi-circular ring 23 is fixedly connected to the circumferential side of the opening and closing ring 13, and a semi-circular plate 15 aligned with the opening and closing ring 13 is fixedly connected to the bottom inner wall of the fixing frame 16.

[0027] Working Principle: The device is moved to the fillet weld on the outer wall of the tank. Rotating screw 22 causes square column 6 to move, which in turn causes screw 7 to rotate. Screw 7 then moves moving plate 21, which in turn moves toothed plate 20. Toothed plate 20 rotates rotating shaft 19, which in turn rotates two fixed columns 1 in opposite directions.

Simultaneously, spring 10 pushes rotating plates 3 and 4 to rotate, which in turn rotate shielding strips 5 and 9. This ensures that rotating plates 3, 4, 5, and 9 completely surround the fillet weld area to be sprayed, facilitating effective spraying. To prevent the penetrant or developer from being blown away by external wind, which could prevent it from fully covering the fillet weld on the outer wall of the tank and affecting the penetration detection effect of the device on the fillet weld of the outer wall of the tank, the rotating plate 3 and the shielding strip 5 are pushed to open the opening ring 13 and the semi-circular ring 23. The spray can 14 is placed in the fixed frame 16 and the opening and closing plate 13 and the semi-circular ring 23 are reset. The fixed frame 16 is rotated, which drives the spray can 14 to rotate, so that the spray can 14 and the fillet weld of the tank body form a certain angle. This allows the device to adjust the angle between the spray can 14 and the fillet weld according to the penetration detection needs, improving the applicability of the device. The motor 24 is started, which drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the cam 17 to rotate. The cam 17 squeezes the spray can 14 and sprays the penetrant or developer onto the fillet weld of the tank body. The device is moved, and the device drives the spray can 14 to spray the penetrant or developer along the fillet weld of the outer wall of the tank body.
