Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0024] Reference Figure 1-6 , Hot-rolled alloy steel flaw detection device, including a base 1 and an ultrasonic flaw detector 7, the upper end of the base 1 is provided with a first support plate 2, a second support plate 4 and a support rod 6, the first support plate 2 and The second support plate 4 is on the same plane, and the support rod 6 is located between the first support plate 2 and the second support plate 4, and the first support plate 2 is provided with a first drive disk 3, The number of the first drive disks 3 is two, and there is a gap between the first drive disks 3. The first drive disks 3 are mounted on the first support plate 2 through a first rotating shaft, and one of the first rotating shafts has another A first motor is connected to one end, and the first rotating shafts are meshed with gears. When the first motor rotates, the two first drive disks 3 can rotate at the same time. The first drive disk 3 is of a hollow structure, and the first Evenly distributed first through holes are provided on the side wall of the drive disk 3, a first through hole adjustment mechanism is provided inside the first drive disk 3, and the first drive disk 3 is communicated with one end of the connecting pipe 8. The other end of the connecting pipe 8 is connected to the side wall of the waste tank 9, an induced draft fan 10 is installed at the upper end of the waste tank 9, and the inlet end of the induced draft fan 10 is in communication with the waste tank 9, and the support rod The upper end of 6 is provided with the ultrasonic flaw detector 7.
[0025] Further, the second support plate 4 is provided with a second drive disk 5, the number of the second drive disk 5 is two, and there is a gap between the second drive disks 5, the second drive disk 5 passes through the second rotating shaft Installed on the second support plate 4, and one of the second rotating shafts is connected with a second motor at the other end, and the second rotating shafts are meshed with gears. When the second motor rotates, the two second drive discs 5 can At the same time, the ultrasonic flaw detector 7 is provided with a horizontally arranged fourth through hole. The fourth through hole is located on the line connecting the gap between the first drive disk 3 and the gap between the second drive disk 5. The second drive disk 5 It is used to reduce the burden of the first drive disc 3 and supports the alloy steel.
[0026] Further, the first through-hole adjustment mechanism includes a fixed shell 13, a magnet block 14 and a spring 15. The fixed shell 13 is inserted with the magnet block 14, and the magnet block 14 and the fixed shell 13 are connected to each other. For the spring 15, one end of the fixed shell 13 is fixedly connected to the inner wall of the first drive disk 3, and an end of the fixed shell 13 close to the first drive disk 3 is provided with an opening, and the opening is communicated with the first through hole, The magnet block 14 is provided with a second through hole, the second through hole is T-shaped, and the side wall of the fixed shell 13 is provided with two third through holes. The third through hole is connected to the second through hole. The horizontal part of the hole is matched and connected. When the device is not running, the horizontal part of the second through hole does not overlap with the third through hole, and external air cannot easily enter the inside of the first drive disk 3. When the device is running, the magnet block 14 is exposed to alloy When the steel is attracted, the magnet block 14 moves into the first through hole, and the horizontal part of the second through hole coincides with the third through hole. Outside air can enter the inside of the first drive plate 3. The spring 15 is used for the magnet block 14 Reset.
[0027] Further, a connecting joint 11 is connected to the middle of one end of the first drive disc 3, a connecting sleeve 12 is sleeved on the outside of the connecting joint 11, and a rubber sealing ring is provided at the connection between the connecting sleeve 12 and the connecting joint 11, In addition, the connecting sleeve 12 is communicated with one end of the connecting pipe 8, and the connecting joint 11 is matched with the sleeve 12, so that the first drive plate 3 can ensure the normal flow of gas when the first drive disc 3 rotates.
[0028] Further, the outlet end of the induced draft fan 10 is provided with filter cotton, which can prevent dust from entering the air again.
[0029] Further, a clamping block is provided on the side wall of the magnet block 14, and a sliding groove is arranged on the inner wall of the fixed shell 13, and the clamping block is inserted inside the sliding groove, and the sliding groove prevents the magnet block 14 from The fixed shell 13 rotates inside, so that the second through hole on the magnet block 14 can communicate with the third through hole.
[0030] In this implementation, when the device is in use, the first motor, the second motor, and the induced draft fan 10 are started, and the alloy steel to be inspected is passed through the gap between the first drive plate 3, the ultrasonic flaw detector 7 and the second drive plate in turn In the gap between 5, the first motor drives the first drive plate 3 to rotate, the first drive plate 3 can push the alloy steel to move forward, and the first drive plate 3 is connected to the induced draft fan 10 through the connecting pipe 8. The induced draft fan 10 Dust can be sucked into the waste tank 9 through the first drive plate 3, which is convenient for the work of the ultrasonic flaw detector 10. The first drive plate 3 is provided with a plurality of fixed shells 13, and the fixed shell 13 is provided with a magnet block 14. When the block 14 and the alloy steel are close to each other, the magnet block 14 will attract the alloy steel. At this time, the magnet block 14 approaches the alloy steel. The horizontal part of the second through hole communicates with the third through hole. The vertical part is connected with the first through hole. At this time, the impurities on the alloy steel can smoothly enter the first drive disk 3 with the air, and finally enter the waste tank 9, and the magnet block 14 can only be close to the alloy steel. It only moves, so that only part of the first through holes on the first drive plate 3 remain in communication with the first drive plate. When the power of the induced draft fan 10 is rated, the air flow rate near the partially opened first through hole is fast, and the air flow rate is fast. It is convenient to blow off the impurities on the alloy steel.
[0031] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
