Description

Technical Field

[0001] This utility model relates to the field of construction inspection technology, and in particular to a vision-based steel structure construction quality appearance inspection device. Background Technology

[0002] Steel rods are rod-shaped components made primarily of steel, playing a crucial role in numerous engineering fields. They possess high strength, good toughness and ductility, capable of withstanding significant tensile, compressive, and bending moments, and adapting to diverse stress environments. They come in various shapes, including round, square, and rectangular, and can be customized to meet specific needs. Steel rod manufacturing processes are mature, allowing them to be combined with other components to form various structures through welding, bolting, and other methods. In construction, they serve as the supporting framework of frame structures; in bridges, they help bear vehicle loads; and in mechanical equipment, they ensure the stable operation of components. Due to their excellent performance, steel rods have become an indispensable material in modern engineering construction. Visual inspection of surface cracks and fissures in steel rods is a critical step in ensuring their quality and safety. Inspectors typically use natural or artificial light to conduct a comprehensive and detailed visual inspection of the steel rod surface, promptly identifying surface problems, preventing the use of defective rods, and preventing potential safety accidents.

[0003] During production, transportation, and storage, steel rods inevitably come into contact with various contaminants such as dust, oil, and rust. These impurities adhere to the surface of the rods, masking actual defects such as cracks and scratches, making it difficult for inspectors to accurately judge the actual condition of the steel rods and affecting the accuracy of appearance inspection.

[0004] Therefore, it is necessary to provide a vision-based steel structure construction quality appearance inspection device to solve the above-mentioned technical problems. Utility Model Content

[0015] The present invention will be further described below with reference to the embodiments.

[0016] Please see Figure 1-5 This utility model provides a vision-based steel structure construction quality appearance inspection device, including a base plate 5, a seat plate 3 fixed to the top side of the base plate 5, a lead screw 4 inside the seat plate 3, the two ends of the lead screw 4 being rotatably connected to the two end side walls of the seat plate 3 respectively, a servo motor 6 fixed to the outer side wall of the seat plate 3, the output end of the servo motor 6 being fixed to one end of the lead screw 4, a nut sleeve 7 threaded onto the lead screw 4, a protruding rod 9 fixed to the side of the nut sleeve 7, a guide groove 8 slidably adapted to the protruding rod 9 on the inner side wall of the seat plate 3, a cleaning component 1 for cleaning the surface of the rod connected to the nut sleeve 7, and a clamping component 2 for clamping the rod on the seat plate 3; in use, the steel rod to be inspected is placed inside the seat plate 3 and clamped by the clamping component. 2. Clamp and fix both ends of the steel rod to prevent it from shaking during the cleaning process. Start the servo motor 6 to work. The output end of the servo motor 6 drives the lead screw 4 to rotate back and forth. The lead screw 9 and the guide groove 8 guide and limit the movement of the nut sleeve 7. The rotating lead screw 4 drives the nut sleeve 7 to move back and forth. The nut sleeve 7 drives the cleaning component 1 to move along the length of the steel rod. The cleaning component 1 sprays the cleaning liquid evenly and finely onto all parts of the steel rod surface, thoroughly cleaning the steel rod. This facilitates the detection of surface cracks and the visual inspection of the steel rod. The cleaning is convenient and effectively improves the cleaning efficiency and the accuracy of visual inspection.

[0017] Further as Figure 1 , Figure 3 and Figure 4As shown, it is worth noting that the cleaning component 1 includes a connecting rod 105 fixed to the side of the nut sleeve 7. A liquid cylinder 101 is fixed to the end of the connecting rod 105 away from the nut sleeve 7. The liquid cylinder 101 has a liquid passage chamber inside, and a spray hole 102 communicating with the inside of the liquid cylinder 101 is opened on the inner side of the liquid cylinder 101. Multiple spray holes 102 are provided and are equidistantly distributed. A water pump 104 is fixed to the top of the nut sleeve 7. A liquid delivery pipe 103 is connected between the output end of the water pump 104 and the inside of the liquid cylinder 101. The output end of the servo motor 6 drives the lead screw 4 to move in both directions. The reciprocating rotation, with the cooperation of the protruding rod 9 and the guide groove 8, guides and limits the movement of the nut sleeve 7. The rotating screw 4 drives the nut sleeve 7 to reciprocate, and the nut sleeve 7 drives the liquid cylinder 101 to move along the length of the steel rod. The cleaning fluid is delivered into the liquid cylinder 101 through the liquid delivery pipe 103 and evenly sprayed onto the surface of the steel rod through multiple spray holes 102, thoroughly cleaning the steel rod. This facilitates the detection of surface cracks and the visual inspection of the steel rod. The cleaning is convenient, effectively improving the cleaning efficiency of the steel rod and the accuracy of visual inspection.

[0018] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth noting that the clamping assembly 2 includes a nut sleeve 208 fixed inside the side wall of the seat plate 3. A threaded rod 201 is threadedly connected to the nut sleeve 208. A support rod 205, coaxially arranged with the threaded rod 201, is fixed on the inner side wall of the seat plate 3. A clamping plate 206 is fixed to the end of the support rod 205. In actual operation, by rotating the threaded rod 201, the steel rod to be tested is placed inside the seat plate 3 through the end of the threaded rod 201 and the clamping plate 206, and the two ends of the steel rod are clamped and fixed, thereby preventing the steel rod from shaking during the cleaning process.

[0019] This solution has the following working process: By rotating the threaded rod 201, the two ends of the steel rod are clamped and fixed by the end of the threaded rod 201 and the clamping plate 206. The output end of the servo motor 6 drives the lead screw 4 to rotate in both directions. The movement of the nut sleeve 7 is guided and limited by the cooperation of the convex rod 9 and the guide groove 8. Thus, the rotating lead screw 4 drives the nut sleeve 7 to move back and forth. The nut sleeve 7 drives the liquid cylinder 101 to move along the length of the steel rod. The cleaning fluid is delivered into the liquid cylinder 101 through the liquid delivery pipe 103 and evenly sprayed onto the surface of the steel rod through multiple spray holes 102, so as to thoroughly clean the steel rod and facilitate the detection of cracks on the surface of the steel rod.

[0020] Further as Figure 5As shown, it is worth noting that the end of the threaded rod 201 is provided with a beveled end 202, and a rubber pad 207 is attached and fixed to the side of the clamping plate 206; in actual operation, the rubber pad 207 effectively increases the stability of the clamping of the steel component.

[0021] Further as Figure 5 As shown, it is worth noting that an end plate 203 is fixed to the end of the threaded rod 201, and a handle rod 204 is fixed to the side of the end plate 203. A rubber sleeve is fitted onto the surface of the handle rod 204. In actual operation, the above structure facilitates the rotation and adjustment of the threaded rod 201, making operation convenient.

[0022] In summary: The output of the servo motor 6 drives the lead screw 4 to rotate reciprocally in both directions. The convex rod 9 and the guide groove 8 guide and limit the movement of the nut sleeve 7. The rotating lead screw 4 drives the nut sleeve 7 to move reciprocally, which in turn drives the cleaning component 1 to move along the length of the steel rod. The cleaning component 1 then sprays the cleaning fluid evenly and finely onto all parts of the steel rod surface, thoroughly cleaning the steel rod. This facilitates the detection of surface cracks and the visual inspection of the steel rod. The cleaning is convenient, effectively improving the cleaning efficiency and the accuracy of visual inspection.

[0023] The servo motor 6 can be purchased from the market. The servo motor 6 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
