Description

Technical Field

[0001] This invention belongs to the field of manufacturing and testing technology of liquefied natural gas storage and transportation equipment, specifically relating to an automated testing device for rigid foamed boards used in liquefied natural gas storage. Background Technology

[0002] Liquefied natural gas (LNG) storage and transportation equipment (such as LNG carrier cargo tanks and large land-based storage tanks) is a key facility for the storage and transportation of cryogenic LNG. The space between its inner and outer walls is usually filled with rigid foam boards to provide thermal insulation and structural support, while effectively reducing the overall weight. During the molding process, due to uneven foaming reaction or raw material distribution problems, defects such as pores and cavities are easily generated inside the rigid foam boards. These defects will seriously weaken the insulation effect and mechanical strength of the boards, thereby affecting the safety and service life of the entire LNG storage and transportation system. Therefore, after the foam boards are finished, ultrasonic flaw detection equipment is required to conduct internal quality inspection to identify whether there are any defective areas.

[0003] Currently, in the ultrasonic testing process of rigid foamed panels, the panels are typically conveyed to the testing station via roller conveyor lines. However, LNG storage applications utilize foamed panels in various specifications and models, with significant differences in length, width, and thickness. Existing testing equipment employs relatively simple conveying and positioning methods, primarily relying on manual adjustment of the panel's position on the rollers or using the rollers' own friction to roughly guide the panel into the testing area. This approach has several drawbacks: firstly, manual adjustment is inefficient and lacks positional accuracy; differences in adjustment habits among operators also lead to inconsistent test results. Secondly, the foamed panels are prone to shifting during roller conveying, preventing them from accurately reaching the working area directly below the ultrasonic probe. This causes the probe's scanning path to deviate from the predetermined area, resulting in undetected internal defects and potential quality issues. Therefore, we need to provide an automated testing device for rigid foamed panels used in LNG storage. Summary of the Invention

[0004] The purpose of this invention is to provide an automated testing device for rigid foamed panels used in liquefied natural gas storage. By setting a foamed panel limiting mechanism, the device can actively clamp and limit the two sides of the rigid foamed panel according to its different specifications.

It can accommodate the rapid switching of multiple panel specifications, ensure the stability of the panel's posture during clamping, and guarantee the accuracy of the ultrasonic detector's scanning path inside the panel, thus solving the problem.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides, for example Figures 1-7 An automated testing device for rigid foamed panels used in liquefied natural gas storage is shown, comprising a frame 1, a roller assembly 2 for conveying rigid foamed panels is rotatably mounted inside the frame 1, and a driver for driving the rollers inside the roller assembly 2 is provided inside the frame 1; and an ultrasonic detector 3 is mounted on the top of the frame 1 and used to test the rigid foamed panels. A foam board limiting mechanism 4 is mounted on the top of the frame 1. The foam board limiting mechanism 4 is used to clamp rigid foam boards of different specifications on the top of the roller group 2 and move them to the working area below the ultrasonic detector 3. By setting the foam board limiting mechanism 4, the two sides of the rigid foam board can be actively clamped and limited according to the different specifications of the rigid foam board. In the clamping state, the board is moved as a whole to the working area below the ultrasonic detector 3. A moving seat 41 is set on the top of the frame 1, and the moving seat 41 is moved as a whole with the help of the sliding part 42. At the same time, the first cylinder 43 drives the two moving platforms 44 to move closer or further away, so as to adapt to foam boards of different width specifications. The second cylinder 6 drives the sliding plate 5 and the side plate 7 to further clamp the side of the board, forming a multi-level adjustable clamping and positioning structure. It can be compatible with the rapid switching of multiple specifications of boards, ensure the stability of the board posture during the clamping process, and ensure the accuracy of the scanning path of the ultrasonic detector 3 inside the board.

[0021] like Figure 4As shown, the foam board limiting mechanism 4 includes a movable seat 41, which is slidably mounted on one side of the top of the frame 1 via a sliding member 42. Two first cylinders 43 are fixedly mounted on the top of the movable seat 41, and a movable platform 44 is fixedly mounted on one side of each of the two first cylinders 43 facing away from each other. Two first cylinders 43 are fixed to the top of the movable base 41 in a back-to-back arrangement, meaning that the cylinder bodies of both cylinders are fixedly connected to the movable base 41, and the extended ends of the piston rods face opposite sides of the movable base 41. When the two first cylinders 43 operate synchronously, their respective piston rods push the movable platforms 44 fixed to their ends to move away from or towards each other, thereby achieving rapid adjustment of the distance between the two movable platforms 44. This allows the limiting mechanism to be flexibly adjusted according to the actual width of the foam board, ensuring that boards of different specifications can obtain an effective clamping foundation. The two first cylinders 43 are not synchronous cylinders.

[0022] like Figure 4 As shown, a slide plate 5 is slidably mounted on the top of each of the two moving platforms 44. A second cylinder 6 for moving the slide plate 5 is fixedly mounted on the top of the moving platform 44. A side plate 7 is fixedly mounted on the adjacent side of each of the two slide plates 5. The side plate 7 is used to clamp the side of the rigid foam board. Two slide bars 8 are fixedly mounted on the bottom of the slide plate 5. A slide rail 9 is slidably mounted on the bottom of each of the two slide bars 8, and the slide rail 9 is fixed to the top of the moving platform 44. The slide plate 5 forms a sliding guide structure with two slide bars 8 at the bottom and two slide rails 9 fixed on the top of the moving platform 44. The configuration of double slide rails 9 and slide bars 8 ensures that the slide plate 5 has high linear motion accuracy and anti-eccentric load capacity during movement. The cylinder body of the second cylinder 6 is fixed on the top of the moving platform 44, and its piston rod end is fixedly connected to the slide plate 5. When the second cylinder 6 extends or retracts, it drives the slide plate 5 to slide back and forth along the slide rail 9. The side plate 7 is fixedly installed on the side of the slide plate 5 facing the foam board. Its working surface is a flat surface, which is used to form a surface contact clamp with the side of the foam board. The second cylinders 6 on the two moving platforms 44 can be controlled independently or synchronously. When the two second cylinders 6 on both sides extend at the same time, the two side plates 7 move from both sides of the foam board toward the middle and apply clamping force to achieve precise lateral positioning of the foam board. The two second cylinders 6 are not synchronous cylinders.

[0023] like Figure 3 and Figure 4As shown, two fixed plates 10 are fixedly installed on one side of the movable seat 41, and a movable plate 11 is provided on one side of each of the two fixed plates 10. A pusher 12 for moving the movable plate 11 is provided in the frame 1. The pusher 12 is used to push the rigid foam board to one side of the two fixed plates 10. During the clamping and positioning process, the pusher 12 drives the movable plate 11 to move towards the fixed plate 10. The movable plate 11 contacts one side edge of the foam board and pushes it towards the fixed plate 10 until the other side edge of the foam board abuts against the fixed plate 10, thereby correcting and limiting the position of the foam board in the conveying direction. The two fixed plates 10 provide a stable positioning reference surface, and the movable plate 11 provides an active pushing force under the drive of the pusher 12.

[0024] like Figure 3 As shown, the pushing component 12 includes a plate 121 fixed in the frame 1. Two slide rods 122 are fixedly installed on one side of the plate 121. A track plate 123 is slidably installed on the surface of the two slide rods 122. The top of the track plate 123 is fixedly installed to the bottom of the movable plate 11. A third cylinder 124 for pushing the track plate 123 to move is fixedly installed on one side of the plate 121. The plate 121 of the pusher 12 is fixedly installed inside the frame 1 as a basic support component, and its position is fixed relative to the frame 1. Two parallel sliding rods 122 are fixedly installed on one side of the plate 121. The two sliding rods 122 together form the guide support structure of the track plate 123. The track plate 123 is simultaneously slidably fitted onto the surface of the two sliding rods 122 and can reciprocate along the axial direction of the sliding rods 122. The parallel arrangement of the two sliding rods 122 ensures that the track plate 123 will not deflect or tilt during the sliding process. The top of the track plate 123 is fixedly connected to the bottom of the movable plate 11, so that the movable plate 11 moves synchronously with the track plate 123. The cylinder body of the third cylinder 124 is fixed on the plate 121, and the end of its piston rod is connected to the track plate 123. When the third cylinder 124 extends or retracts, its piston rod directly drives the track plate 123 to slide along the sliding rods 122, thereby causing the movable plate 11 to move closer to or away from the fixed plate 10.

[0025] like Figure 4As shown, the sliding member 42 includes two moving rails 421 fixed to the bottom of the moving seat 41. Each moving rail 421 has a slidably mounted track bar 422 at its bottom. Both track bars 422 are fixed to the top of the frame 1. The two moving rails 421 are parallel to and fixed to the bottom of the moving seat 41, moving synchronously with the moving seat 41. The two track bars 422 are correspondingly fixed to the top of the frame 1, with their length direction aligned with the length direction of the frame 1. The upper part of the track bar 422 and the lower part of the moving rail 421 form a sliding fit. A linear guide pair or a dovetail slide structure can be used between the moving rails 421 and the track bars 422 to ensure high guiding accuracy and load-bearing capacity during relative sliding. The two parallel sliding fit pairs jointly constrain the motion freedom of the moving seat 41, allowing it to move only linearly along the length direction of the frame 1, and preventing offset in directions perpendicular to the conveying direction or vertically.

[0026] like Figure 6 As shown, it also includes a drive component 13 for driving the movable base 41. The drive component 13 includes a motor 131 embedded in the movable base 41. The output end of the motor 131 is mounted with an output wheel 132 via a coupling. A rack 133 that meshes with the output wheel 132 is fixedly mounted on the top of the frame 1. The motor 131 is embedded inside the movable base 41, saving external installation space. At the same time, the motor 131 housing is fixedly connected to the movable base 41, making the motor 131 a part of the movable base 41. When the motor 131 is running, its output torque is transmitted through... The power is transmitted to the output wheel 132 via the coupling. The output wheel 132 is a gear structure, and its outer circumferential teeth mesh with the rack 133 fixedly installed on the top of the frame 1. The rack 133 is arranged along the length of the frame 1, and its length covers the entire stroke range required by the moving seat 41. When the motor 131 starts to rotate forward or in reverse, the output wheel 132 rotates accordingly. Since the rack 133 is fixed, the output wheel 132 rolls along the rack 133 under the action of the meshing force, thereby driving the entire moving seat 41 and the motor 131 to move linearly along the direction of the rack 133.

[0027] like Figure 2As shown, the frame 1 is provided with a plurality of pushing parts 14. Each of the pushing parts 14 includes two fourth cylinders 141 fixed inside the frame 1. A floating frame 142 is fixedly installed on the top of each of the two fourth cylinders 141, and two pushing rollers 143 are provided on the top of the floating frame 142. The pushing rollers 143 are staggered and distributed in the roller group 2. The two fourth cylinders 141 are synchronous cylinders (existing technology). The two fourth cylinders 141 synchronously drive the floating frame 142, ensuring the horizontality of the floating frame 142 during the lifting and lowering process, so that the two pushing rollers 143 contact the bottom of the foam board at the same time and the force is uniform. The pushing rollers 143 are installed in a rotating manner. When the foam board is moved in the pushing state, the pushing rollers 143 can be passively rotated with the movement of the foam board, converting sliding friction into rolling friction, and further reducing the transfer resistance. The cylinder bodies of both fourth cylinders 141 are fixed inside the frame 1, with their piston rods extending vertically upwards. The tops of the two piston rods are fixedly connected to the same floating frame 142, allowing the floating frame 142 to move vertically up and down under the combined drive of the two fourth cylinders 141. Two upward push rollers 143 are rotatably mounted on the top of the floating frame 142. The axial direction of the upward push rollers 143 is parallel to the axial direction of the roller group 2, and the projection positions of the two upward push rollers 143 on the horizontal plane are staggered between adjacent rollers in the roller group 2. That is, each upward push roller 143 is located in the gap between two adjacent rollers, allowing the upward push roller 143 to extend upwards from below the roller group 2 through the gap between the rollers.

[0028] like Figure 1 As shown, the ultrasonic detector 3 is fixed to the top of the frame 1 by two support brackets 15. The support bracket 15 near the foam board limiting mechanism 4 is U-shaped and has a recessed groove 16 inside for the movement of the foam board limiting mechanism 4. The ultrasonic detector 3 is mounted on the top of the frame 1 by the two support brackets 15, which together bear the weight of the ultrasonic detector 3 and fix it at a predetermined height. The support bracket 15 near the foam board limiting mechanism 4 is designed with a U-shaped structure, that is, the support bracket 15 has a U-shaped outline with its opening facing the foam board limiting mechanism 4 in the top view, and its hollow internal area forms the recessed groove 16. The width and depth of the relief groove 16 are adapted to the height and width of the moving seat 41 in the foam board limiting mechanism 4. When the moving seat 41 carries the clamped foam board and moves along the top of the frame 1 toward the ultrasonic detector 3 to the detection position, the part of the moving seat 41 near the support bracket 15 can extend into the relief groove 16, so that the foam board clamped by the moving seat 41 can be located exactly below the ultrasonic detector 3.

[0029] like Figure 4As shown, a protective cover 17 is fixedly installed on the top of the movable seat 41. The protective cover 17 can be made of metal plate or engineering plastic plate, and its interior forms a receiving space to enclose the first cylinder 43, the second cylinder 6 and their connecting pipes.

[0030] Working principle: The rigid foam board is placed on the roller group 2 inside the frame 1. The driver drives each roller in the roller group 2 to rotate synchronously, thereby conveying the foam board forward along the length of the frame 1 and making it enter the preparation area to be tested.

[0031] When the foamed board reaches the preset clamping position under the conveying action of the roller group 2, the foamed board limiting mechanism 4 is installed on one side of the top of the frame frame 1 through the sliding member 42. The sliding member 42 consists of two moving rails 421 fixed to the bottom of the moving seat 41 and two track bars 422 fixed to the top of the frame frame 1. The moving rails 421 and track bars 422 slide in cooperation, so that the moving seat 41 can slide smoothly in a straight line along the length direction of the frame frame 1. Two first cylinders 43 are fixedly installed on the top of the moving seat 41. The two first cylinders 43 are arranged in opposite directions, that is, the piston rods of the two first cylinders 43 extend away from each other. When the two first cylinders 43 act at the same time, their piston rods push the moving platform 44 fixedly connected to their respective ends, so that the distance between the two moving platforms 44 increases or decreases, thereby adapting to the clamping requirements of foamed boards of different widths.

[0032] After the two moving platforms 44 are in place, the second cylinder 6 installed on top of each moving platform 44 is activated. The piston rod end of the second cylinder 6 is fixedly connected to the slide plate 5. Two slide bars 8 are fixedly installed on the bottom of the slide plate 5. The two slide bars 8 are respectively in sliding engagement with two slide rails 9 fixed on the top of the moving platform 44, so that the slide plate 5 can slide smoothly along the direction perpendicular to the foam board conveying under the drive of the second cylinder 6. A side plate 7 is fixedly installed on the side of the slide plate 5 facing the foam board. The two side plates 7 are respectively driven by the two second cylinders 6 to move from both sides of the foam board toward the middle until they are tightly abutting against the two sides of the foam board, thereby achieving precise clamping and fixing of the foam board in the left and right directions.

[0033] The pusher 12, which is installed inside the frame 1, participates in the auxiliary positioning synchronously. The pusher 12 includes a plate 121 fixed inside the frame 1. Two parallel sliding rods 122 are fixedly installed on one side of the plate 121. A track plate 123 is slidably installed on the surface of the two sliding rods 122. The track plate 123 can reciprocate along the axis of the sliding rods 122. The top of the track plate 123 is fixedly connected to the movable plate 11. A third cylinder 124 is also fixedly installed on one side of the plate 121. The piston rod end of the third cylinder 124 is connected to the track plate 123. When the third cylinder 124 extends, it pushes the track plate 123 to slide along the sliding rods 122. The track plate 123 drives the movable plate 11 on its top to move towards the fixed plate 10. The movable plate 11 and the fixed plate 10 are located on both sides of the foamed board along the conveying direction. The pusher 12 pushes the foamed board to one side of the moving seat 41.

[0034] After completing the above clamping, positioning, and attitude correction, the entire moving seat 41 is driven to carry the clamped foam board and move it horizontally along the top of the frame 1 toward the ultrasonic detector 3. That is, the driving component 13 includes a motor 131 embedded in the moving seat 41. After the motor 131 is started, the output wheel 132 rotates and, through meshing with the rack 133, converts the rotational motion into linear motion of the moving seat 41 along the length of the rack 133, thereby accurately moving the foam board to the working area directly below the ultrasonic detector 3. In order to ensure the height of the foam board, the push part 14 provided in the frame 1 starts to operate. The pusher 14 includes two fourth cylinders 141 fixed inside the frame 1. The piston rods of the two fourth cylinders 141 are fixedly connected to the same floating frame 142. Two push rollers 143 are rotatably mounted on the top of the floating frame 142. The two push rollers 143 are staggered between adjacent rollers in the roller group 2. When the fourth cylinder 141 extends, its piston rod pushes the floating frame 142 and the push rollers 143 to rise synchronously. The top of the push rollers 143 is higher than the bearing surface of the roller group 2, thereby partially lifting the foam board located at the top of the roller group 2, and then clamping the foam board.

[0035] When the foam board is precisely moved by the moving seat 41 to the working area below the ultrasonic detector 3, the ultrasonic detector 3 (existing technology) is activated. The ultrasonic detector 3 is fixedly installed on the top of the frame frame 1 by two support brackets 15. One of the support brackets 15 near the foam board limiting mechanism 4 is designed with a U-shaped structure and has a relief groove 16 inside. When the moving seat 41 carries the foam board to the detection position, a part of the moving seat 41 can be embedded in the relief groove 16, thereby avoiding mechanical interference with the support bracket 15. The ultrasonic detector 3 emits ultrasonic signals into the foam board, receives the reflected echoes and analyzes them, thereby identifying whether there are defects such as holes and cavities inside the foam board.

[0036] After the inspection is completed, the foam board is lowered, the foam board limiting mechanism 4 retracts and resets, the drive component 13 operates, the foam board falls back onto the surface of the roller group 2, and the foam board that has completed the inspection is output along the frame 1 to the next process.
