When inspecting the weld of the welded steel structure, the cylinder 202 is first started, and then one end of the cylinder 202 extends and drives the connecting plate 204 to move , then the connecting plate 204 drives the second motor 206 and the grinding disc 208 to move until the grinding disc 208 contacts the weld of the steel structure, and then the second motor 206 and the fifth motor 9 are started respectively. At this time, the fifth motor 9 drives the steel structure to rotate through the three-jaw chuck 10, and at the same time, the second motor 206 drives the grinding disc 208 to repair and grind the weld of the steel structure until the protruding weld is polished smooth, and then the first motor 203 is started, and the first motor 203 drives the connecting block 20 through the first threaded rod 205 7 moves, and then the connecting block 207 drives the electric push rod 209 and the detection head 210 to move. When the detection head 210 is horizontally aligned with the weld of the steel structure, one end of the electric push rod 209 extends out and drives the detection head 210 to move to one side of the weld. At this time, the ultrasonic detector 201 is started, and the ultrasonic detector 201 detects the weld through the detection head 210. At the same time, the fifth motor 9 is used to rotate the steel structure at a low speed to make the detection more comprehensive. If the weld is poor, it can be re-welded.

[0022] Furthermore, the detection head 210 is electrically connected to the ultrasonic detector 201, and one end of the cylinder 202 passes through the fixed plate 5 and is connected to the connecting plate 204.

After the two sets of roller devices 304 are adjusted to a suitable distance, the welded steel structure is placed on the surface of the roller device 304, and its weld must be in the center position of the two sets of roller devices 304.

Through the setting of the forward and reverse screw rods 302, when in use, the forward and reverse screw rods 302 drive the slide plates 303 to move toward or away from each other through their own forward and reverse rotation, thereby adjusting the distance between the roller devices 304 to adapt to steel structures of different sizes.

[0026] Furthermore, one end of the third motor 301 passes through the device body 1 and is connected to the forward and reverse screws 302. Two sets of roller devices 304 are provided.

[0028] After the two sets of roller devices 304 are adjusted to a suitable distance, the welded steel structure is placed on the surface of the roller device 304, and its weld seam must be at the center position of the two sets of roller devices 304. Then, the fourth motor 4 is started. The fourth motor 4 drives the sliding plate 8 to move through the second threaded rod 6. After the sliding plate 8 moves to the position, the three-jaw chuck 10 on one side of the sliding plate is against the welded steel structure. Then, the three-jaw chuck 10 is adjusted to clamp the welded steel structure. At this time, the support and fixation of the welded steel structure are completed. When inspecting the weld of the welded steel structure, the cylinder 202 is first started. Then, one end of the cylinder 202 extends out and drives the connecting plate 204 to move. 4 drives the second motor 206 and the grinding disc 208 to move until the grinding disc 208 contacts the weld of the steel structure, and then the second motor 206 and the fifth motor 9 are started respectively.

Then the first motor 203 is started. The first motor 203 drives the connecting block 207 to move through the first threaded rod 205. Then the connecting block 207 drives the electric push rod 209 and the detection head 210 to move. When the detection head 210 is horizontally aligned with the weld of the steel structure, one end of the electric push rod 209 extends and drives the detection head 210 to move to one side of the weld. At this time, the ultrasonic detector 201 is started. The ultrasonic detector 201 detects the weld through the detection head 210. At the same time, the fifth motor 9 rotates the steel structure at a low speed to make it more comprehensive. If the weld is poor, it can be re-welded.
