[0016] The present invention has the following beneficial effects: 1. For the ray detection device for liquefied petroleum gas cylinders in production, by the cooperation of the placement plate and the rollers, the liquefied petroleum gas cylinder is placed on the top of the rollers. The solenoid valve exhaust pipe is used to assist the gas in the air storage tank to be discharged, and then the gas in the air bag pad is discharged. Thus, the outer edge of the placement plate moves down in the inner wall of the fixed cylinder, and the outer edge of the liquefied petroleum gas cylinder near the bottom is limited to the inner wall of the fixed cylinder. The air pump supplies gas to the clamping air bag ring through the arc-shaped groove, assisting the outer edge of the clamping air bag ring to be clamped and limited with the outer edge of the liquefied petroleum gas cylinder. The pressure sensor II detects the air pressure inside the clamping air bag ring and controls the air pump to stop operating, so as to ensure the stable clamping and limitation of the liquefied petroleum gas cylinder, and avoid the position deviation of the liquefied petroleum gas cylinder during the detection process, which affects the measurement accuracy; The air pump supplies gas to the inside of the air bag pad through the inner wall of the air storage tank, the through groove and the communication groove, and then the air bag pad is used to push the placement plate upward until the top of the placement plate is on the same plane as the top of the fixed cylinder. Then, the liquefied petroleum gas cylinder is moved, and the rollers are used to assist the convenient pushing of the liquefied petroleum gas cylinder, so as to facilitate the loading and unloading of the liquefied petroleum gas cylinder; The air pump supplies gas to the inner cavity of the outer cylinder through the air supply groove and the inner wall of the circular groove, thereby assisting the outer edge of the middle cylinder to slide in the inner wall of the outer cylinder, driving the outer edge of the inner cylinder to slide in the inner wall of the middle cylinder, and then driving the side surface of the slider to slide.

[0017] 2. The ray detection device for liquefied petroleum gas cylinders in production, through the combined use of the adjusting ring and the rotating ring, drives the gear to rotate by means of the motor, thus driving the convex tooth ring to rotate by the gear, and then driving the rotating ring to rotate on the inner wall of the adjusting ring by the convex tooth ring, and further assisting the ray detection assembly to perform circumferential detection on the liquefied petroleum gas cylinder along with the rotating ring.

Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

A ray flaw detection assembly 35 is fixedly assembled on the inner wall of the rotating ring 34. An arc-shaped plate 43 is arranged on the inner wall of the rotating ring 34, and a contact sensor II 44 is fixedly assembled on the inner wall of the arc-shaped plate 43; In the above structure, through the combined use of the placement plate 5 and the roller 6, it is convenient to lap a conveyor structure such as a ramp on the side of the device to assist in loading the liquefied petroleum gas cylinder, and the roller 6 is used to assist in pushing the liquefied petroleum gas cylinder for loading and unloading. Moreover, the diameter of the outer edge of the placement plate 5 is adapted to the diameter of the inner wall at the top of the fixed cylinder 4, so as to ensure that when the outer edge of the placement plate 5 slides in the inner wall of the fixed cylinder 4, the sliding path of the placement plate 5 is more stable, thus ensuring that the liquefied petroleum gas cylinder can slide stably. Through the combined use of the fixed ring 29 and the adjusting ring 30, by rotating the adjusting ring 30 in the inner wall of the fixed ring 29, it is used to assist in driving the ray detection component 35 to rotate, and then it is convenient to adjust the detection angle of the outer surface of the liquefied petroleum gas cylinder, so as to facilitate the stable detection of different angles of the grooves and protrusions on the outer surface of the liquefied petroleum gas cylinder, and further ensure the stability of ray detection. The ray detection component 35 includes a ray source and a digital detector, and the ray source and the digital detector are respectively installed at both ends of the inner wall of the rotating ring 34. The ray source can use X-rays or gamma rays. X-rays are suitable for thin to medium-thickness materials (such as the wall thickness of the gas cylinder ≤ 50 mm), with high flexibility and adjustable energy. Gamma rays have strong penetration and are suitable for thick-walled equipment (such as oil storage tanks or thick-walled pipelines) and can be selected according to requirements. After the ray penetrates the object, internal defects will form a contrast in the digital image due to density differences. The height and diameter of the outer edges of the fixed ring 29, the adjusting ring 30, and the rotating ring 34 are all the same. And when the bottom of the fixed ring 29 is lapped with the top of the lapping frame 3, the top of the fixed ring 29 and the top of the placement plate 5 are on the same horizontal plane, thus further ensuring the stable loading and unloading of the liquefied petroleum gas cylinder.

A rubber pad 45 is fixedly assembled on the inner wall of the adjusting ring 30, and the outer edge of the convex rod 28 is in close contact with the inner wall of the rubber pad 45 through the inner walls of the slider 25 and the fixing ring 29; In the above structure, through the combined use of the second tension spring 27 and the convex rod 28, the second tension spring 27 is used to pull the convex rod 28 to move in the inner wall of the slider 25, and further assist the side surface of the convex rod 28 to move away from the inner wall of the rubber pad 45, so as to avoid the interference of the convex rod 28 on the rotation of the adjusting ring 30. After the adjusting ring 30 rotates, the side surface of the convex rod 28 fits with the inner wall of the rubber pad 45, so as to assist the adjustment ring 30 to be limited again.

[0028] In a preferred embodiment, a U-shaped frame 31 is fixedly assembled on the top of the adjusting ring 30, a motor 32 is fixedly assembled on the top of the U-shaped frame 31, the output shaft of the motor 32 passes through the inner wall of the U-shaped frame 31 and is fixedly assembled with a gear 33, and the bottom of the gear 33 is rotatably connected to the top of the adjusting ring 30.

A ultrasonic distance sensor 41 is fixedly assembled on the side surface of the inner wall of the sliding cylinder 40; In the above structure, the motor 37 drives the rotating rod 38 to rotate, so as to drive the adjusting ring 30 to rotate in the inner wall of the fixing ring 29 by means of the rotating rod 38, and drive the ray detection component 35 to adjust the angle through the rotating ring 34 by means of the adjusting ring 30, so as to facilitate the ray detection component 35 to detect the outer surface of the liquefied petroleum gas cylinder at different angles. By the combined use of the sliding cylinder 40 and the sliding rod 42, the diameter of the outer edge of the sliding rod 42 is adapted to the diameter of the inner wall of the sliding cylinder 40, so as to ensure that when the outer edge of the sliding rod 42 slides in the inner wall of the sliding cylinder 40, the gas inside the sliding cylinder 40 is in a sealed state. Therefore, when the outer edge of the sliding rod 42 slides under force in the inner wall of the sliding cylinder 40, the gas inside the sliding cylinder 40 is compressed to push the sliding rod 42 to reset, and has an auxiliary shock absorption effect on the sliding rod 42.

Since the sliding rod 42 is rotatably connected to the arc-shaped plate 43, when the arc-shaped plate 43 rotates with the rotating ring 34, the arc-shaped plate 43 can still stably fit with the outer surface of the liquefied petroleum gas cylinder.

Through the combined use of the first pressure sensor 17 and the second pressure sensor 18, the first pressure sensor 17 is used to assist in detecting the internal pressure of the clamping airbag ring 15, and the second pressure sensor 18 is used to assist in detecting the internal pressure of the airbag pad 7, so as to facilitate controlling the air pump 12 to stop operating when the pressure is too high, and thus assist the device to operate more stably.

[0031] Working principle: When the device is in use, place the liquefied petroleum gas cylinder on the top of the roller 6. Use the solenoid valve exhaust pipe 11 to assist in discharging the gas inside the air storage tank 10, and then assist in discharging the gas inside the airbag pad 7.

Supply air to the clamping airbag ring 15 through the arc-shaped groove 14 by the air pump 12, assisting the outer edge of the clamping airbag ring 15 to be clamped and limited with the outer edge of the liquefied petroleum gas cylinder. Use the pressure sensor II 18 to detect the air pressure inside the clamping airbag ring 15 and control the air pump 12 to stop operating, thereby ensuring the stable clamping and limitation of the liquefied petroleum gas cylinder, avoiding the position deviation of the liquefied petroleum gas cylinder during the flaw detection process and affecting the measurement accuracy. The air pump 12 supplies air to the inner cavity of the outer cylinder 19 through the air supply groove 23 and the inner wall of the circular groove 24, thereby assisting the outer edge of the middle cylinder 20 to slide in the inner wall of the outer cylinder 19 and driving the outer edge of the inner cylinder 21 to slide in the inner wall of the middle cylinder 20. Furthermore, drive the side surface of the slider 25 to slide, and use the gas in the inner cylinder 21 to push the convex rod 28 to move until the side surface of the convex rod 28 is in close contact with the inner wall of the rubber pad 45, thereby ensuring the limitation of the adjusting ring 30 in the inner wall of the fixed ring 29 and ensuring the stable upward movement of the ray flaw detection assembly 35 for flaw detection. Drive the gear 33 to rotate by the motor 37, thereby driving the convex tooth ring 36 to rotate by the gear 33. Furthermore, drive the rotating ring 34 to rotate in the inner wall of the adjusting ring 30 by the convex tooth ring 36, and then assist the ray flaw detection assembly 35 to perform circumferential detection on the liquefied petroleum gas cylinder along with the rotating ring 34. When the top of the contact sensor I 26 contacts the top of the inner wall of the side frame 2, the air pump 12 stops operating, thereby assisting in discharging the gas inside the outer cylinder 19, the middle cylinder 20, and the inner cylinder 21. Furthermore, assist the convex rod 28 to move away from the side surface of the rubber pad 45. Drive the outer edge of the adjusting ring 30 to rotate in the inner wall of the fixed ring 29 by the motor 37, and then assist in driving the ray flaw detection assembly 35 to perform angle adjustment, thereby facilitating the stable detection of the outer surface of the liquefied petroleum gas cylinder by the ray flaw detection assembly 35 as required. The electric telescopic rod 39 drives the arc-shaped plate 43 to move until the inner wall of the arc-shaped plate 43 contacts the outer surface of the liquefied petroleum gas cylinder. When the contact sensor II 44 contacts the outer surface of the liquefied petroleum gas cylinder, control the electric telescopic rod 39 to stop moving. Then, when the arc-shaped plate 43 is driven by the rotating ring 34 to perform height adjustment, the arc-shaped plate 43 is driven by the convex and concave parts of the outer surface of the liquefied petroleum gas cylinder, and then assist the ultrasonic distance measuring sensor 41 to detect the distance from the sliding rod 42, thereby further performing stable flaw detection on the outer surface of the liquefied petroleum gas cylinder.
