[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0030] Please see Figures 1-7This utility model provides an ultrasonic steel plate flaw detection device, including a pad plate, a pad block fixedly connected to the top of the pad plate, a groove at the top of the pad block, a side plate 1 fixedly connected within the groove, a protective plate 101 fixedly connected to one side of the side plate 1, a fixing plate fixedly connected to the side of the protective plate 101 away from the side plate 1, a fixing block fixedly connected to one side of the fixing plate, a sliding groove at the side of the fixing block away from the fixing plate, a threaded rod 102 fixedly connected within the sliding groove, and a threaded sleeve 103 threadedly connected to the surface of the threaded rod 102. A first pulley 104 is fixedly connected to the top of the sleeve 103. A belt 105 is driven through the surface of the first pulley 104. A second pulley 106 is driven through the end of the belt 105 away from the first pulley 104. A servo motor 107 is fixedly connected to the bottom of the second pulley 106. A shelf is fixedly connected to the bottom of the servo motor 107. The end of the shelf away from the servo motor 107 is rotatably connected to the threaded sleeve 103. During operation, after the servo motor 107 is powered on and started, it outputs rotational power to drive the second pulley 106. 6. At high speed, the second pulley 106 transmits power to the first pulley 104 via the tensioned belt 105. When the first pulley 104 rotates, it drives the threaded sleeve 103, which is fixedly connected to it, to rotate on the threaded rod 102. Because the threaded sleeve 103 and the threaded rod 102 are connected by a thread, the rotational motion of the threaded sleeve 103 is converted into linear motion along the axial direction of the threaded rod 102. The threaded transmission ensures that the threaded sleeve 103 will not slip after the power input stops, maintaining its current stable position. The linear movement of the cylinder 103 drives the placement plate to move synchronously. The placement plate is hinged to the first movable plate 110 through the connecting block 108 and the first fixed shaft 109. When the placement plate moves, the first movable plate 110 rotates. The first movable plate 110 drives the second movable plate 112 to move through the second fixed shaft 111. The second movable plate 112 then drives the third movable plate to move. Finally, the third movable plate drives the push plate to push the machine body to move, thereby enabling the probe to move in different directions to meet the different needs of steel plate flaw detection.
[0031] Furthermore, such as Figure 1 and Figure 2 As shown, a connecting block 108 is fixedly connected to the top of the shelf, a first fixed shaft 109 is fixedly connected to the top of the connecting block 108, a first movable plate 110 is movably connected to the surface of the first fixed shaft 109, a second fixed shaft 111 is movably connected to the end of the first movable plate 110 away from the first fixed shaft 109, a second movable plate 112 is movably connected to the surface of the second fixed shaft 111, a third movable plate is movably connected to one end of the second movable plate 112, a push plate is fixedly connected to the end of the third movable plate away from the second movable plate 112, an organism is fixedly connected to the side of the push plate away from the side plate 1, a probe tube is fixedly connected to the bottom of the organism, and a probe is fixedly connected to the bottom of the probe tube.
[0032] Furthermore, such as Figure 1 and Figure 2 As shown, a base plate 2 is provided at the bottom of the pad, a buffer plate is fixedly connected to the top of the base plate 2, a stabilizing plate is fixedly connected to the top of the buffer plate, a stabilizing block is fixedly connected to the top of the stabilizing plate, a groove is formed at the top of the stabilizing block, a roller is fixedly connected in the groove, a first sliding block 201 is sleeved on the surface of the roller, a first limiting shaft 202 is fixedly connected to the top of the first sliding block 201, a limiting plate is movably connected to the surface of the first limiting shaft 202, and a second limiting shaft 203 is movably connected to the end of the limiting plate away from the first limiting shaft 202. The top of the second limiting shaft 203 is fixedly connected to... There is a second sliding block, and a top plate 204 is provided on the top of the second sliding block. The top plate 204 is fixedly connected to the pad. During operation, the first sliding block 201 and the second sliding block drive the extension plate fixedly connected to them to move during the sliding process. The extension plate stretches or compresses the buffer spring 3, and the buffer spring 3 undergoes elastic deformation, converting the kinetic energy generated by vibration into the elastic potential energy of the spring. The symmetrically distributed first sliding block 201, second sliding block and buffer spring 3 can absorb vibration energy evenly from multiple directions, effectively reducing the vibration amplitude of the device and reducing the impact of vibration on the flaw detection equipment.
[0033] Furthermore, such as Figure 2 and Figure 3 As shown, an extension plate is fixedly connected to one side of both the first sliding block 201 and the second sliding block, and a buffer spring 3 is fixedly connected to the top of the extension plate. The first sliding block 201 and the second sliding block are symmetrically distributed, and the bottom and top of the buffer spring 3 are fixedly connected to the extension plate.
[0034] Furthermore, such as Figure 2 and Figure 3 As shown, a connecting plate 301 is fixedly connected to one side of the first sliding block 201. A limit hole is started at the top of the connecting plate 301, and a limit bolt 302 is slidably connected in the limit hole. A docking plate 4 is provided at the bottom of the limit bolt 302. A limit hole is started at the top of the docking plate 4. The docking plate 4 is fixedly connected to one side of the stabilizing block. During operation, when it is necessary to adjust the position of the device, the operator manually pulls out the limit bolt 302. After the limit bolt 302 is disengaged from the limit holes of the connecting plate 301 and the docking plate 4, the first sliding block 201 loses its limit constraint and can slide freely on the roller. At this time, the operator can easily push the device to move it to a suitable position in the horizontal direction. After the device position is adjusted, the limit bolt 302 is reinserted into the limit holes of the connecting plate 301 and the docking plate 4. The limit bolt 302 passes through the limit holes of the two plates, restricting the movement of the first sliding block 201, thereby stabilizing and fixing the device in the current position, thus enabling the device to be quickly positioned and fixed.
[0035] Furthermore, such as Figure 1 and Figure 2As shown, a support column 5 is fixedly connected to the bottom of the base plate 2, and a buffer pad 501 is fixedly connected to the bottom of the support column 5. The support column 5 and the buffer pad 501 are symmetrically distributed through the base plate 2.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, a base 6 is fixedly connected to the top of the top plate 204. The top of the base 6 has a groove, and a fixed seat is fixedly connected in the groove. A steel plate placement plate 601 is fixedly connected to the top of the fixed seat. A connecting rod is fixedly connected to the top of the steel plate placement plate 601, and a protective frame is fixedly connected to the top of the connecting rod.
[0037] Furthermore, such as Figure 3 and Figure 5 As shown, a limiting block is fixedly connected to the top of the fixed base. A sliding groove is provided on the top of the limiting block, and a moving block 7 is slidably connected in the sliding groove. A clamping rod 701 is fixedly connected to the side of the moving block 7 near the steel plate placement plate 601. During operation, according to the actual size of the steel plate, the operator manually pushes the moving block 7 to slide in the sliding groove on the top of the limiting block. The moving block 7 drives the clamping rod 701 to move. When the clamping rod 701 contacts the side of the steel plate, the operator continues to push the moving block 7 so that the clamping rod 701 applies a clamping force to the steel plate, thereby firmly fixing the steel plate on the steel plate placement plate 601, thus adapting to the fixing requirements of steel plates of different widths and thicknesses.
[0038] Working principle: During operation, after the servo motor 107 is powered on and started, it outputs rotational power to drive the second pulley 106 to rotate at high speed. The second pulley 106 transmits power to the first pulley 104 through the tensioned belt 105. When the first pulley 104 rotates, it drives the threaded sleeve 103, which is fixedly connected to it, to rotate on the threaded rod 102. Because the threaded sleeve 103 and the threaded rod 102 are connected by threads, the rotational motion of the threaded sleeve 103 is converted into linear motion along the axial direction of the threaded rod 102. The threaded transmission ensures that the threaded sleeve 103 will not slip after the power input stops, maintaining its current stable position. The linear movement of the threaded sleeve 103... The movable plate moves synchronously. The plate is hinged to the first movable plate 110 via connecting block 108 and the first fixed shaft 109. When the plate moves, the first movable plate 110 rotates, driving the second movable plate 112 via the second fixed shaft 111. The second movable plate 112 then drives the third movable plate, which in turn drives the push plate to move the machine body. This allows the probe to move in different directions to meet different requirements for steel plate flaw detection. During the sliding process, the first sliding block 201 and the second sliding block drive the extension plate fixedly connected to them to move. The extension plate stretches or compresses the buffer spring 3, which in turn releases... The device undergoes elastic deformation, converting the kinetic energy generated by vibration into the elastic potential energy of the spring. The symmetrically distributed first sliding block 201, second sliding block, and buffer spring 3 can uniformly absorb vibration energy from multiple directions, effectively reducing the vibration amplitude of the device and minimizing the impact of vibration on the flaw detection equipment. When the device position needs to be adjusted, the operator manually pulls out the limit bolt 302. After the limit bolt 302 disengages from the limit holes of the connecting plate 301 and the mating plate 4, the first sliding block 201 loses its limiting constraint and can slide freely on the roller. At this time, the operator can easily push the device to move it to a suitable position in the horizontal direction. After the device position is adjusted, the limit bolt is removed. 302 is reinserted into the limiting holes of the connecting plate 301 and the docking plate 4. The limiting bolt 302 passes through the limiting holes of the two plates, restricting the movement of the first sliding block 201, thereby stabilizing the device in the current position and enabling the device to be positioned and fixed quickly. According to the actual size of the steel plate, the operator manually pushes the moving block 7 to slide in the groove at the top of the limiting block. The moving block 7 drives the clamping rod 701 to move. When the clamping rod 701 contacts the side of the steel plate, the moving block 7 is pushed to apply clamping force to the steel plate, thereby firmly fixing the steel plate on the steel plate placement plate 601, thus adapting to the fixing requirements of steel plates of different widths and thicknesses.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
