Description

Technical Field

[0001] This utility model relates to the field of steel pipe testing technology, and more specifically to a fully automatic ultrasonic testing device for steel pipe welds. Background Technology

[0002] A steel pipe weld refers to the joint formed during the welding process of a steel pipe. In the production or engineering construction process, in order to manufacture longer steel pipes, two or more sections of steel pipes are spliced ​​together. The joint is melted and mixed by high-temperature welding, and after cooling, a circumferential or longitudinal weld is formed.

[0003] To improve the welding quality of steel pipes, the weld is often inspected after welding. Ultrasonic testing involves scanning the weld area by placing a probe against it. Based on the transmission time and response magnitude of the sound waves, it can indicate whether there are defects in the weld area of ​​the steel plate.

[0004] However, during the inspection of steel pipe welds, workers manually move the probe around the weld area to inspect the steel pipe. This manual method makes it difficult to ensure the proper spacing and direction of movement between the probe and the steel pipe, which can lead to deviations and fluctuations in the inspection data, thus affecting the accuracy of the inspection data.

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-5 As shown, a fully automatic ultrasonic testing device for steel pipe welds includes a steel pipe body 4 and a weld zone 41 disposed on the steel pipe body 4, and further includes:

[0032] Support frame 1, the support frame 1 has a ring 142 attached to the steel pipe body 4, and a slide rail 13 is attached to the support frame 1;

[0033] Stabilizing unit 2 is symmetrically arranged on support frame 1, and stabilizing unit 2 includes stabilizing wheel 21 that is attached to the steel pipe;

[0034] The detection unit 3 is slidably connected to the slide rail 13. The detection unit 3 includes a second slider 35, a first slider 32, and a fixing block 33 disposed on the first slider 32. The first slider 32 is slidably connected to the slide rail 13.

[0035] The fixed block 33 is provided with a screw 331 that cooperates with the second slider 35. The second slider 35 is fitted with a probe 31 facing the weld area 41. The screw 331 rotates to control the probe 31 to move closer to or away from the weld area 41.

[0036] Specifically, the support frame 1 supports the stabilizing unit 2 and the detection unit 3. When the support frame 1 is placed on the steel pipe body 4, the stabilizing wheel 21 can provide a certain supporting force to the support frame 1. The stabilizing wheel 21 is arranged in two sets opposite to each other on the support frame 1. Then, the screw 331 is rotated to control the second slider 35 to slide on the fixed block 33, so as to drive the probe 31 to move closer or further away from the steel pipe body 4, so that the probe 31 is adjusted to a suitable position. The first slider 32 is controlled to slide on the slide rail 13, so that the probe 31 surrounds the steel pipe body 4 to perform ultrasonic detection. The display screen on the detector is observed to record the detection data, thereby improving the accuracy of the detection data.

[0037] As a further embodiment of this utility model, the second slider 35 has a slot, in which a clamping plate 352 is slidably disposed. A spring 353 is disposed between the clamping plate 352 and the second slider 35. The clamping plate 352 engages with the probe 31, and the probe 31 is engaged in the slot. Under the push of the spring 353, the two clamping plates 352 slide relative to each other to clamp the probe 31.

[0038] As a further embodiment of this utility model, a limiting rod 354 is provided on one side of the slot, and an arc-shaped wire groove 351 that cooperates with the probe 31 is provided on the other side. The wiring of the probe 31 is engaged in the arc-shaped wire groove 351 to protect the wiring. The limiting rod 354 is used to prevent the probe 31 from contacting the steel pipe body 4.

[0039] As a further embodiment of this utility model, the support frame 1 includes a first support body 11 and a second support body 12 that cooperate with each other. The slide rail 13 is semi-circular and is respectively engaged with the first support body 11 and the second support body 12. The slide rail 13 is provided with a slide groove 132. The first slider 32 slides in the slide groove 132. The first support body 11 and the second support body 12 are both provided with grooves 16. A plurality of locking rods 131 are evenly distributed on the slide rail 13. The slide rail 13 is engaged with the groove 16 by means of the locking rods 131.

[0040] As a further embodiment of this utility model, a bracket 34 is provided on the first slider 32, and a motor 341 is provided on the support frame 1. The output end of the motor 341 is provided with a pulley 342 that fits against the slide groove 132. The model of the motor 341 is 46JBX. The motor 341 is used as a power source to control the rotation of the pulley 342. In this way, the detection unit 3 is controlled to slide on the slide rail 13 by the pulley 342. A collar 142 is provided on the pulley 342 to reduce the phenomenon of slippage of the pulley 342.

[0041] As a further embodiment of this utility model, the second support body 12 is provided with a rotating end 121, and a support rod 122 is provided on the rotating end 121. The first support body 11 rotates on the first support body 11 via the support rod 122. After the steel pipe body 4 is welded, the steel pipe body 4 is relatively long at this time, and the first support body 11 and the second support body 12 rotate via the support rod 122 to improve the installation efficiency of the support frame 1.

[0042] As a further embodiment of this utility model, a second locking member 15 is provided on the second support body 12, and a buckle 151 is provided on the second locking member 15. A first locking member 14 is provided on the first support body 11, and a lever 141 is provided on the first locking member 14. A collar 142 that engages with the buckle 151 is provided on the lever 141. When the support frame 1 is located on the steel pipe body 4, the lever 141 can be swung to engage the collar 142 with the buckle 151, and then the lever 141 can be rotated to make the first support body 11 and the second support body 12 fit together and be fixed.

[0043] As a further embodiment of this utility model, the stabilizing unit 2 also includes a torsion spring 24, a support block 25, and a swing arm 22 rotatably connected to the support block 25. The torsion spring 24 is disposed on the support block 25 and cooperates with the swing arm 22. A stabilizing wheel 21 is disposed on the swing arm 22. One end of the torsion spring 24 is in contact with the support block 25, while the other end pushes against the swing arm 22, so that the stabilizing wheel 21 on the swing arm 22 is in contact with the steel pipe. Furthermore, the stabilizing unit 2 is symmetrically arranged on one side of the support frame 1 (e.g., Figure 2 As shown, to improve the stability of the device, two sets of stabilizing units 2 can be set on the other side of the support frame 1 for detection. Since the motor 341 moves slowly and uniformly during detection, no large supporting force is required, and multiple sets of stabilizing units 2 can be set as needed.

[0044] As a further embodiment of this utility model, a connecting rod is provided on the swing arm 22, and a locking cover 23 is provided on the connecting rod. The stabilizing wheel 21 is provided on the connecting rod through the locking cover 23. The stabilizing wheel 21 can rotate on the connecting rod. After the detection of one position is completed, the movable support frame 1 can slide on the steel pipe body 4 by the bracket 34, thereby performing multi-segment detection of the weld area 41.

[0045] As a further embodiment provided by this utility model, the stabilizing wheel 21 is a rubber wheel, which consists of two sets of rollers. The material of the two sets of rollers and the rubber improves the fit with the steel pipe body 4, thereby improving the stability of the support frame 1.

[0046] Working principle: Before testing, the first locking piece 14 and the second locking piece 15 are not locked. Hold the first support body 11 and the second support body 12, and rotate the first support body 11 on the second support body 12 to put the ring 142 of the support frame 1 on the steel pipe body 4. Then, through the cooperation of the first locking piece 14 and the second locking piece 15, the support frame 1 is fixed to the weld area 41. At this time, under the elastic action of the torsion spring 24, the two relatively opposite stabilizing wheels 21 are pushed to fit against the outer wall of the steel pipe body 4 to improve the stability of the support frame 1. Then, the motor 341 controls the pulley 342 to rotate, so that the first slider 32 slides slowly on the slide rail 13, so that the probe 31 surrounds the weld area 41 to perform ultrasonic testing, thereby improving the accuracy of the test on the steel pipe body 4.
