Description

Technical Field

[0001] This utility model relates to the field of pressure vessel testing technology, specifically to a metal pressure vessel flaw detection device. Background Technology

[0002] A pressure vessel is a closed device that holds gas or liquid under a certain pressure. Its maximum working pressure is greater than or equal to 0.1 MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 2.5 MPa·L for gases, liquefied gases, and liquids with a maximum working temperature higher than or equal to the standard boiling point.

[0003] Patent CN218496831U discloses a metal pressure vessel flaw detection device, which includes a base, a drive assembly installed in the inner cavity of the base, and L-shaped support plates fixed at both ends of the top of the base. The two sets of L-shaped support plates are connected to the base by a lead screw through bearings. The device, through the cooperation of the L-shaped support plates, electric push rod, lead screw, base and drive assembly, can drive the ultrasonic probe to move up and down, which facilitates all-round detection of the pressure vessel body, realizes automated detection, and improves the detection efficiency of the device.

[0004] However, this device only has one turntable. After the pressure vessel body to be inspected is fixed on the turntable and the inspection is completed, the pressure vessel body must be released from its restraints and removed before a new container to be inspected can be placed in it. This means that the device cannot work during the process of releasing and removing the pressure vessel and installing the new container, which greatly affects the inspection efficiency. To address this issue, a metal pressure vessel flaw detection device is proposed to solve the problem that the existing detection device cannot continuously inspect pressure vessels, thus affecting the inspection efficiency.

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.

[0023] Example: See Figure 1-4 A metal pressure vessel flaw detection device includes a base 1, a U-shaped seat 2 slidably disposed on the top of the base 1, an electric push rod 12 fixedly connected to one side of the U-shaped seat 2, a rotating seat 3 symmetrically and rotatably disposed on the top of the U-shaped seat 2, a pressure vessel 4 disposed on the top of the rotating seat 3, a clamping mechanism 5 symmetrically disposed on the top of the rotating seat 3, a column 6 fixedly connected to one side of the top of the base 1, a flaw detection head 7 disposed on one side of the column 6, rubber wheels 8 symmetrically disposed at the bottom of the U-shaped seat 2, the rubber wheels 8 being fixedly connected to the rotating seat 3 by a rotating shaft 9, a motor 10 fixedly connected inside the base 1, a second rubber wheel 11 fixedly connected to the output shaft of the motor 10, a drive mechanism 13 disposed inside the column 6, and a detection mechanism 14 disposed at one end of the column 6.

[0024] Furthermore, one end of the electric push rod 12 is fixedly connected to the base 1, and the surfaces of the rubber wheel 8 and the second rubber wheel 11 are very rough, with one of the rubber wheels 8 and the second rubber wheel 11 in flexible compression contact.

[0025] Furthermore, the clamping mechanism 5 includes a vertical block 501 symmetrically fixedly connected to the top of the rotary base 3. A second electric push rod 502 is fixedly connected to one side of the vertical block 501. An arc-shaped clamping plate 503 is fixedly connected to one end of the second electric push rod 502. A flexible anti-slip pad is fixedly connected in the arc groove on the side of the arc-shaped clamping plate 503 facing the pressure vessel 4. When the pressure vessel 4 is placed on the top of the rotary base 3, the second electric push rod 502 is turned on to drive the arc-shaped clamping plate 503 and cooperate with the anti-slip pad to clamp and fix the pressure vessel 4 of different sizes, ensuring the stability of the pressure vessel 4 during the rotational flaw detection process.

[0026] Furthermore, the drive mechanism 13 includes a moving groove 131 opened on one side of the column 6, a moving block 132 is provided in the inner cavity of the moving groove 131, and a screw 133 is rotatably provided in the inner cavity of the moving groove 131.

[0027] Furthermore, the screw 133 passes through the movable block 132 and the two are threadedly connected. A third electric push rod 135 is fixedly connected to one side of the movable block 132. One side of the third electric push rod 135 is fixedly connected to the flaw detector head 7. A servo motor 134 is fixedly connected to the top of the column 6. The output shaft of the servo motor 134 is fixedly connected to the screw 133. The servo motor 134 drives the screw 133, which in turn drives the movable block 132, which is screwed to the screw 133 in the movable groove 131, to move down and adjust the longitudinal position of the flaw detector head 7. The third electric push rod 135 is used to adjust the lateral position of the flaw detector head 7, which facilitates the flaw detection of different pressure vessels 4 and improves the practicality of this metal pressure vessel flaw detection device.

[0028] Furthermore, the inspection mechanism 14 includes a connecting plate 141 disposed at one end of the column 6. A flaw detector 7 is fixedly connected to the bottom of one end of the connecting plate 141. The connecting plate 141 is disposed at one end of the column 6 using a mounting bracket 144. A telescopic shell 142 is fixedly connected to one end of the connecting plate 141. A slot 143 adapted to the telescopic shell 142 is provided on one side of the moving block 132. If the pressure vessel 4 has a top opening and requires internal flaw detection, the connecting plate 141 on the mounting bracket 144 can be removed, and then the telescopic shell 142 can be inserted into the slot 143 in the moving block 132. The telescopic shell 142 can be used to adjust the lateral position of the flaw detector 7 so that it can smoothly enter the interior of the pressure vessel 4. With the help of the drive mechanism 13, it can be moved down to rotate and inspect the pressure vessel 4, further improving the practicality of this metal pressure vessel flaw detection device.

[0029] Working principle: When using this metal pressure vessel flaw detection device, two pressure vessels 4 are simultaneously clamped onto the rotating base 3 using the clamping mechanism 5. Then, the drive mechanism 13 inside the column 6 drives the flaw detection head 7 to move downwards, and in conjunction with the second rubber wheel 11 on the output shaft of the motor 10 and the rubber wheel 8 on the rotating shaft 9, the pressure vessel 4 rotates for flaw detection. After flaw detection is completed, the electric push rod 12 drives the U-shaped seat 2 to move to the other end, moving another pressure vessel 4 to be tested to the bottom of the flaw detection head 7 for further flaw detection, and replacing the tested pressure vessel 4. This process is repeated to achieve continuous detection, improve efficiency, and solve the problem that existing detection devices cannot continuously detect pressure vessels, thus affecting detection efficiency. When moving the U-shaped seat 2 to replace the pressure vessel 4, the rubber wheel 8 located at the bottom of the pressure vessel 4 inside the U-shaped seat 2 will move to press against the second rubber wheel 11, thereby ensuring that the rotating base 3 can drive the pressure vessel 4 to rotate, facilitating comprehensive flaw detection of the exterior of the pressure vessel 4.
