Description

Technical Field

[0001] The present application relates to the field of ultrasonic detection technology, and in particular to an ultrasonic surface defect detection device. Background Art

[0002] Ultrasonic metal detection is widely used in quality control, safety assessment and fault diagnosis of metal products. The principle used is that when ultrasonic waves propagate in metal materials, they will encounter different acoustic impedance interfaces, which will reflect, refract and transform waveforms. When ultrasonic waves encounter defects or changes in the density, speed of sound and other characteristics of the material itself, reflected waves will be generated. The reflected waves are captured by the receiving probe and converted into electrical signals. Through the data processing and display system, it can be analyzed whether there are defects inside the material and the specific location and nature of the defects.

[0003] At present, in the process of producing seamless steel pipes, ultrasonic surface defect detection equipment is used to inspect the quality of steel pipes because steel pipes are usually long and heavy. During the inspection process, operators are required to use handling equipment to transport the steel pipes to the location of the ultrasonic surface defect detection equipment in sequence, and then use tools to slowly and evenly rotate the steel pipes so that the ultrasonic surface defect detection equipment can inspect the outer edge of the steel pipe.

[0004] However, when operating the transfer equipment to transfer steel pipes, operators need to pay attention to various safety issues between factories, which results in a lot of time spent on transferring steel pipes. In addition, since the number of steel pipes that need to be inspected in the factory is usually large, the inspection efficiency of the steel pipes is low, which is a deficiency.

[0041] Workers stack the steel pipes 1 on the pipe rack 2 using transportation equipment, and then start the angle control cylinder 379 through the control system according to the diameter of the steel pipe 1. The piston rod of the angle control cylinder 379 extends, and the connecting block 378 drives the angle wheel 35 to rotate around the rotation center of the ball shaft 376 through the angle control ring 377. At the same time, the linkage ring 373 on the angle wheel 35 drives the secondary connecting rod 374 to rotate synchronously. During this process, relative sliding occurs between the secondary connecting rod 374 and the linkage ring 373.

When the baffle plate 45 resists the steel pipe 1 and transfers the steel pipe 1 to between the directional wheel 32 and the angular wheel 35, the fan-shaped arc surface of the counterweight plate 46 is used to resist the steel pipe 1 on the pipe rack 2.

[0046] Reference Figure 1 and Figure 2 A fixing and taking rack 6 is arranged below the pipe rack 2, and a pipe limiting rack 7 and a pipe blocking rack 8 are vertically slidably arranged on the fixing and taking rack 6. The spacing between the pipe limiting rack 7 and the pipe blocking rack 8 is greater than the diameter of the steel pipe 1 and less than 1.5 times the diameter of the steel pipe 1.

A support block 54 is arranged on the detection seat 51, and a support compression spring 57 is supported between the support block 54 and the detection seat 51.

[0053] Reference Figure 1 and Figure 5 A vertical connecting screw 58 is welded on the detection seat 51, and the connecting screw 58 slides through the support block 54. An adjusting nut 59 is threadedly connected to the connecting screw 58 on the side of the support block 54 facing away from the support compression spring 57. Two support wheels 55 are horizontally slidably arranged on the support block 54. The axis of the support wheel 55 is tilted toward the steel pipe 1 from top to bottom, and a sliding member 56 for driving the support wheel 55 to slide is arranged on the support block 54.

The linkage shaft 371 drives the end plate 372 to rotate synchronously. The end plate 372 drives the linkage ring 373 to rotate through the main connecting rod 375 and the secondary connecting rod 374. The linkage ring 373 drives the angle wheel 35 to rotate synchronously. The friction between the angle wheel 35 and the steel pipe 1 drives the steel pipe 1 to rotate continuously during the transportation along its axial direction.

[0056] When the steel pipe 1 is transported to the clamping frame 13, the control system starts the clamping cylinder 14, and the piston rod of the clamping cylinder 14 drives the clamping wheel 15 to clamp the steel pipe 1 on the directional wheel 32 and the angular wheel 35. Before the steel pipe 1 is transported, the worker turns the adjusting nut 59, adjusts the height of the support block 54 by the support compression spring 57, and then turns the bidirectional screw 561. The bidirectional screw 561 controls the two support columns 562 to approach each other, so that the support wheels 55 on the two support columns 562 simultaneously approach and abut against the outer wall of the steel pipe 1, and then the ultrasonic probe 53 continuously detects the steel pipe 1 during the rotation process.

[0057] The implementation principle of an ultrasonic surface defect detection device in an embodiment of the present application is as follows: workers stack steel pipes 1 on pipe racks 2 through transportation equipment, and then start the angle control cylinder 379 through the control system according to the diameter of the steel pipe 1. The piston rod of the angle control cylinder 379 extends, and the connecting block 378 drives the angle wheel 35 to rotate around the rotation center of the ball shaft 376 through the angle control ring 377. At the same time, the linkage ring 373 on the angle wheel 35 drives the secondary link 374 to rotate synchronously. During this process, relative sliding occurs between the secondary link 374 and the linkage ring 373.

[0058] At the same time, the secondary connecting rod 374 drives the main connecting rod 375 to slide along the axis direction of the end plate 372, and the secondary connecting rod 374 and the main connecting rod 375 rotate relative to each other, thereby changing the angle between the axis of the angle wheel 35 and the axis of the steel pipe 1, thereby controlling the conveying speed of the steel pipe 1, and then the control system starts the adjusting cylinder 342. Under the guidance of the guide rail 341, the piston rod of the adjusting cylinder 342 pushes the adjusting frame 33, and the adjusting frame 33 drives the angle wheel 35 to approach the directional wheel 32, so as to adapt to the diameter of the steel pipe 1.

[0059] Then the control system starts the pipe taking motor 43, the output shaft of the pipe taking motor 43 drives the pipe taking shaft 42 to rotate in the opposite direction, the pipe taking shaft 42 drives the pipe taking plate 44 to rotate in the opposite direction, the pipe taking plate 44 drives the counterweight plate 46 to rotate in the opposite direction and gradually approaches the pressure plate 10, as the counterweight plate 46 gradually rotates to the bottom of the steel pipe 1 on the pipe rack 2.

[0060] The pressure plate 10 compresses the reset compression spring 11, and at the same time, the pressure plate 10 drives the pipe blocking rack 8 to descend. Under the transmission action of the gear 9, the pipe limiting rack 7 rises vertically, and the first steel pipe 1 closest to the fan-shaped arc surface of the counterweight plate 46 rolls from the fan-shaped arc surface of the counterweight plate 46 to the pipe taking plate 44. At the same time, the second steel pipe 1 close to the fan-shaped arc surface of the counterweight plate 46 is blocked by the pipe limiting rack 7.

[0061] Then the output shaft of the tube taking motor 43 drives the tube taking shaft 42 to rotate forward, the reset compression spring 11 recovers its deformation and pushes the tube blocking rack 8 to rise through the pressure plate 10, and at the same time, under the action of the gear 9, the tube limiting rack 7 descends. At this time, the steel pipe 1 on the tube rack 2 rolls and is blocked by the tube blocking rack 8, and at the same time, the steel pipe 1 on the tube taking plate 44 rolls to the connection between the baffle 45 and the tube taking plate 44. As the tube taking shaft 42 continues to rotate forward, the steel pipe 1 at the connection between the tube taking plate 44 and the baffle 45 is gradually placed between the directional wheel 32 and the angular wheel 35.

[0062] The worker starts the drive motor 361 through the control system. The output shaft of the drive motor 361 transmits the torque to the linkage shaft 371 through the reduction box 362. The linkage shaft 371 drives the end plate 372 to rotate synchronously. The end plate 372 drives the linkage ring 373 to rotate through the main connecting rod 375 and the secondary connecting rod 374. The linkage ring 373 drives the angle wheel 35 to rotate synchronously. The friction between the angle wheel 35 and the steel pipe 1 drives the steel pipe 1 to rotate continuously during the transportation along its axial direction.

[0063] When the steel pipe 1 is transported to the clamping frame 13, the control system starts the clamping cylinder 14, and the piston rod of the clamping cylinder 14 drives the clamping wheel 15 to clamp the steel pipe 1 on the directional wheel 32 and the angular wheel 35. Before the steel pipe 1 is transported, the worker turns the adjusting nut 59, adjusts the height of the support block 54 by the support compression spring 57, and then turns the bidirectional screw 561. The bidirectional screw 561 controls the two support columns 562 to approach each other, so that the support wheels 55 on the two support columns 562 simultaneously approach and abut against the outer wall of the steel pipe 1, and then the ultrasonic probe 53 continuously detects the steel pipe 1 during the rotation process.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
