Description

Technical Field

[0001] This utility model belongs to the field of steel structure inspection technology, and in particular relates to a multifunctional automated ultrasonic inspection device for steel structures. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. After the steel structure is fabricated, it needs to be inspected to ensure that its quality meets the requirements for use, thereby guaranteeing the quality of the building.

[0003] Publication number "CN221007422U" discloses "an ultrasonic testing instrument for building steel structures". With the help of the stabilizing component, the steel structure can be positioned, so that the staff will not tilt when pushing the whole testing device. The ultrasonic testing instrument moves more stably, thereby improving the testing effect. With the help of the rotating component, the ultrasonic testing instrument and the stabilizing component can be rotated, so that both vertical and horizontal steel structures can be tested as needed. It is convenient to use.

[0004] The aforementioned existing technologies still have the following drawbacks in practical implementation:

[0005] During use, the device needs to be manually moved. When a large number of steel structures need to be inspected, the labor intensity is high, which affects the inspection efficiency. Moreover, the function is relatively simple, only having the inspection function. It cannot clean the surface of the steel structure to be inspected. The surface of the steel structure may have dust and other impurities adhering to it, which will affect the ultrasonic flaw detection operation and reduce the accuracy of the inspection. At the same time, it cannot mark unqualified steel structures.

[0006] To address the above issues, we propose a multifunctional automated ultrasonic testing device for steel structures. Utility Model Content

A through groove is opened on the surface of the movable plate, and a lead screw is provided inside the through groove. A movable block is threaded on the lead screw, and a mounting plate is fixed to the bottom of the movable block. An ultrasonic detector is installed at the bottom of the mounting plate, and a marking component is provided on the movable plate.

[0009] A vacuum pump is installed on the top of the fixed plate. A first telescopic hose is connected between the suction end of the vacuum pump and the front end of the vacuum pipe. A conveying pipe is connected to the exhaust end of the vacuum pump. A dust collection box is connected to the end of the conveying pipe away from the vacuum pump. The dust collection box is located on the rear side of the conveying mechanism.

[0010] The marking assembly includes a spray pipe mounted on a movable plate. A nozzle is installed at the lower end of the spray pipe, and a second telescopic hose is connected to the upper end of the spray pipe. A spray pump is installed on the top of the fixed frame. The end of the second telescopic hose away from the spray pipe passes through the fixed frame and is connected to the outlet of the spray pump. A suction pipe is connected to the inlet of the spray pump. A storage tank is provided behind the conveying mechanism, and the end of the suction pipe away from the spray pump extends to the bottom of the inner cavity of the storage tank.

[0011] The conveying mechanism includes a support frame, on which a plurality of rollers are rotatably mounted. Each roller is equipped with a conveying roller, and a transmission chain is provided between the rear ends of two adjacent rollers. A drive motor is mounted on the right side of the rear surface of the support frame via a mounting bracket, and the output end of the drive motor is connected to the rear end of the rightmost roller.

[0015] This invention utilizes a conveying mechanism to facilitate the transport of the steel structure to be inspected. Simultaneously, under the action of the first electric push rod, it allows for the adjustment of the cleaning brush to approach the steel structure during transport. As the steel structure moves, dust and dirt on its surface are swept away. The suction pipe and nozzle further adsorb the swept-away dust and dirt, preventing dust from flying and polluting the work area during cleaning, thus ensuring the cleanliness of the steel structure surface. Furthermore, under the action of the second electric push rod, combined with a movable plate, it facilitates the vertical movement of the ultrasonic detector. The threaded engagement between the lead screw and the movable block allows for the horizontal movement of the ultrasonic detector, enabling convenient inspection of different parts of the steel structure.

This process marks any steel structures that fail inspection, facilitating subsequent standardized processing. Compared to existing technologies, this system integrates cleaning, inspection, and marking of steel structures, effectively improving the efficiency of steel structure inspection.

[0024] This specific embodiment is a multifunctional automated ultrasonic testing device for steel structures, such as... Figures 1-6 As shown, the multifunctional automated ultrasonic testing device for steel structures includes a conveying mechanism. A fixed frame 1 is fixed to the rear side of the conveying mechanism. A fixed plate 2 is fixedly connected to the right side of the fixed frame 1. A first electric push rod 3 is installed at the bottom of the fixed plate 2. A cleaning brush 4 is connected to the telescopic end of the first electric push rod 3. A suction pipe 5 is installed on the left side of the cleaning brush 4 through several pipe clamps. Several suction nozzles 6 are installed on the suction pipe 5. A second electric push rod 10 is installed on the top inner side of the fixed frame 1. A movable plate 11 is connected to the telescopic end of the second electric push rod 10. A through groove 12 is opened on the surface of the movable plate 11. A lead screw 13 is set inside the through groove 12. A movable block 14 is threaded on the lead screw 13. An installation plate 15 is fixed to the bottom of the movable block 14. An ultrasonic detector 16 is installed at the bottom of the installation plate 15. A marking component is set on the movable plate 11.

[0025] The conveying mechanism facilitates the transport of the steel structure to be inspected. Simultaneously, the first electric push rod 3 allows for the adjustment of the cleaning brush 4 to approach the steel structure during transport. As the steel structure moves, it cleans dust and dirt from its surface. The suction pipe 5 and suction nozzle 6 further adsorb the cleaned dust and dirt, preventing dust from flying and polluting the work area when the cleaning brush 4 cleans the steel structure, thus ensuring the cleanliness of the steel structure surface. The second electric push rod 10, combined with the movable plate 11, allows for the adjustment of the ultrasonic detector 16 to move vertically up and down. The threaded engagement between the lead screw 13 and the movable block 14 allows for the adjustment of the ultrasonic detector 16 to move horizontally back and forth, facilitating the inspection of different parts of the steel structure.

[0026] A vacuum pump 7 is installed on the top of the fixed plate 2. A first telescopic hose 8 is connected between the suction end of the vacuum pump 7 and the front end of the vacuum pipe 5. A conveying pipe is connected to the exhaust end of the vacuum pump 7. A dust collection box 9 is connected to the end of the conveying pipe away from the vacuum pump 7. The dust collection box 9 is located on the rear side of the conveying mechanism.

[0027] The marking assembly includes a spray pipe 17, which is mounted on a movable plate 11. A nozzle 18 is installed at the lower end of the spray pipe 17, and a second telescopic hose 19 is connected to the upper end of the spray pipe 17. A spray pump 20 is installed on the top of the fixed frame 1. The end of the second telescopic hose 19 away from the spray pipe 17 passes through the fixed frame 1 and is connected to the outlet of the spray pump 20. A suction pipe is connected to the inlet of the spray pump 20. A storage tank 21 is provided behind the conveying mechanism. The end of the suction pipe away from the spray pump 20 extends to the bottom of the inner cavity of the storage tank 21. Through the cooperation of the spray pump 20 and the suction pipe, the paint inside the storage tank 21 can be easily extracted and transported to the spray pipe 17 via the second telescopic hose 19. The paint is then sprayed onto the surface of the steel structure below through the nozzle 18, marking the steel structure that fails the inspection, which facilitates subsequent unified processing.

[0028] The conveying mechanism includes a support 22, on which several rollers are rotatably mounted. Conveying rollers 23 are mounted on the rollers. A transmission chain 24 is provided between the rear ends of two adjacent rollers. A drive motor 25 is mounted on the right side of the rear surface of the support 22 via a mounting bracket. The output end of the drive motor 25 is connected to the rear end of the rightmost roller.

[0029] Two guide grooves are opened opposite each other on the inner wall of the through groove 12. Guide blocks are fixed on both sides of the movable block 14, which are movably engaged with the guide grooves on both sides. A servo motor 26 is installed on the rear surface of the movable plate 11. The output end of the servo motor 26 is connected to the rear end of the lead screw 13.

[0030] The controller is mounted on the front surface of the bracket 22 via a support rod. The first electric push rod 3, the second electric push rod 10, the ultrasonic detector 16, the dust pump 7, the spray pump 20, the drive motor 25, and the servo motor 26 are all electrically connected to the controller.

[0031] Example:

[0032] When in use, first start the drive motor 25. Under the action of the transmission chain 24, drive several conveyor rollers 23 to rotate synchronously. The staff places the steel structure to be inspected on the right end of the conveying mechanism, and the steel structure is conveyed to the left by the conveyor rollers 23.

[0033] Simultaneously, the first electric push rod 3 and the vacuum pump 7 are activated. By extending the first electric push rod 3 outward, the cleaning brush 4 is adjusted to move downward and approach the steel structure during the conveying process. As the steel structure moves, the dust and dirt on the surface of the steel structure are swept away. At the same time, with the cooperation of the vacuum pump 7 and the first telescopic hose 8, negative pressure is provided to the vacuum pipe 5. Combined with the vacuum nozzle 6, the swept dust and dirt are adsorbed and collected, and transported to the dust collection box 9 through the conveying pipe for unified processing, so as to achieve the purpose of cleaning the surface of the steel structure.

[0034] Next, the second electric push rod 10 is activated. The second electric push rod 10 extends outward, driving the movable plate 11 to move downward, which in turn drives the ultrasonic detector 16 to move downward closer to the cleaned steel structure until the detection probe of the ultrasonic detector 16 contacts the steel structure, thus achieving the purpose of detecting the steel structure. The detection data is displayed on the display screen on the controller for easy viewing by the staff.

[0035] When it is necessary to inspect different parts of the steel structure surface, the servo motor 26 is started, which drives the lead screw 13 to rotate. With the threaded engagement between the lead screw 13 and the movable block 14, and the mutual engagement between the guide block and the guide groove, the mounting plate 15 is moved back and forth stably, which in turn drives the ultrasonic detector 16 to move back and forth in the horizontal direction, making it convenient to inspect different parts of the steel structure.

[0036] When cracks are detected inside the steel structure and it does not meet the usage requirements, the detection results are fed back to the controller, and the controller starts the spray pump 20 to extract the paint from the storage tank 21, which is then transported to the spray pipe 17 through the second telescopic hose 19, and finally sprayed onto the surface of the steel structure through the nozzle 18. This marks the unqualified steel structure for subsequent classification and unified processing.

[0037] Compared with the prior art, the present invention facilitates the transport of steel structures to be inspected through a conveying mechanism, which is suitable for continuous inspection of large batches of steel structures. It solves the drawbacks of the prior art, which requires manual pushing of the device for movement, resulting in high labor intensity and reduced inspection efficiency when a large number of steel structures need to be inspected.

[0038] Simultaneously, through the coordinated operation of the cleaning brush 4, dust pump 7, first telescopic hose 8, dust suction pipe 5, and dust suction nozzle 6, the surface of the steel structure is cleaned of dust and dirt. Meanwhile, with the cooperation of the second electric push rod 10, movable plate 11, lead screw 13, movable block 14, mounting plate 15, and ultrasonic detector 16, different parts of the cleaned steel structure are inspected. Finally, with the cooperation of the spray pump 20, second telescopic hose 19, spray pipe 17, and nozzle 18, paint is sprayed onto the surface of the steel structure that fails inspection, marking the defective steel structure for easier subsequent classification and processing. This solves the problem of existing technologies where the inspection device has a limited function, only capable of inspection, and cannot clean the surface of the steel structure to be inspected. The surface of the steel structure may have dust and other impurities adhering to it, affecting the ultrasonic flaw detection operation and reducing the accuracy of the inspection. Furthermore, it cannot mark defective steel structures, thus facilitating the inspection of steel structures.

[0039] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0040] Meanwhile, the first electric push rod 3, the second electric push rod 10, the ultrasonic detector 16, the dust pump 7, the spray pump 20, the drive motor 25, the servo motor 26, and the controller in this utility model are all purchased from the market. Those skilled in the art can install and wire them according to the requirements.

[0041] Meanwhile, the ultrasonic detector 16 is existing technology already disclosed in the prior art document. Its specific structure, working principle and usage are all existing technologies, and will not be described in detail here.

[0042] All technical features in this embodiment can be freely combined according to actual needs.
