[0002] According to different measuring principles, flaw detectors can be divided into: digital ultrasonic flaw detectors, ultrasonic flaw detectors, magnetic particle flaw detectors, eddy current flaw detectors, X-ray flaw detectors and fluorescent flaw detectors. They are mainly used to detect whether there are defects inside machined parts, such as cracks, sand holes, pores, white spots, inclusions, etc., whether the weld is qualified, and whether there are hidden flaws, so as to determine whether the workpiece is qualified or not. Flaw detectors usually emit ultrasound to the object being tested, and then use its reflection, Doppler effect, transmission, etc. to obtain information inside the object being tested and form an image after processing. After the steel structure is welded, the weld needs to be flaw detected.

[0003] However, in the prior art, when inspecting the welding parts of steel structures, the probe emits ultrasonic waves to the welding parts and forms an image for viewing. However, when inspecting some higher welding parts of steel structures, the workers need to raise their arms and look up to observe for inspection. It is uncomfortable to keep the arms and heads raised for a long time, and it is inconvenient to adjust the inspection points. Utility Model Content

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0023] The utility model provides Figure 1-6As shown, a welding flaw detector includes a detection component 1, two clamping and hanging components 2 and a rotating component 3. The two clamping and hanging components 2 are arranged on one side of the detection component 1 for clamping and fixing on the steel structure. The rotating component 3 is arranged on the two clamping and hanging components 2 for rotating and adjusting the viewing angle. The clamping and hanging components 2 include a rectangular plate 201, a concave support plate 202, a rotating rod 203, a connecting block 204, two torsion springs 205, a clamping plate 1 206 and a clamping plate 207. The rectangular plate 201 is arranged on one side of the detection component 1. On the side, the concave support plate 202 is fixedly mounted on one side outer wall of the rectangular plate 201, the rotating rod 203 is rotatably mounted on the two concave support plates 202, the connecting block 204 is fixedly sleeved on the rotating rod 203, the two torsion springs 205 are slidably sleeved on the rotating rod 203, the ends of the two torsion springs 205 close to each other are fixedly connected to the connecting block 204, and the ends of the two torsion springs 205 away from each other are respectively fixedly connected to the two concave support plates 202, the clamping plate 206 is fixedly mounted on the connecting block 204, the The second clamping plate 207 is hingedly installed on the outer wall of one side of the rectangular plate 201. More specifically, the first clamping plate 206 is pushed upward, and the first clamping plate 206 drives the connecting block 204 to rotate. The rotation of the connecting block 204 drives the torsion spring 205 to twist. The torsion spring 205 is deformed and accumulates elastic force due to the twisting. The connecting block 204 drives the rotating rod 203 to rotate, and the first clamping plate 206 flips over and moves away from the second clamping plate 207. The second clamping plate 207 loses the obstruction of the first clamping plate 206. At this time, the second clamping plate 207 is pushed downward to flip, and an opening is formed between the first clamping plate 206 and the second clamping plate 207 and is connected to the steel structure. The structure is aligned, the splint 1 206 and the splint 207 are moved, and the steel structure is inserted between the splint 1 206 and the splint 207, and the splint 1 206 is loosened. The torsion spring 205 loses the torsional force and releases the elastic force to drive the splint 1 206 to reset. The splint 1 206 and the splint 207 clamp the steel structure. If the cross-section of the steel structure is small, the splint 1 206 is reset to fit the steel structure, and a triangular gap is formed between the splint 207 for hanging, which is convenient for clamping or hanging on the surface of the steel structure, freeing the hands of the user and avoiding the need to move and adjust the detection points by hand.

[0024] In addition, a groove 1 is formed on one side of the outer wall of the first clamping plate 206 , and a groove 2 is formed on one side of the outer wall of the second clamping plate 207 .

[0025] like Figure 1 As shown, the detection component 1 includes a flaw detector 101 and an acoustic wave probe 102 , and the acoustic wave probe 102 is arranged on the flaw detector 101 .

[0026] In addition, four anti-collision corners are fixedly mounted on the flaw detector 101 , and a support block is fixedly mounted on an outer wall of one side of the flaw detector 101 .

[0027] In addition, a fixing block is fixedly installed on one side of the outer wall of the flaw detector 101 , and a C-shaped plate is fixedly installed on one side of the outer wall of the fixing block, and the C-shaped plate is adapted to the sonic probe 102 .

[0028] like Figure 1 As shown, the rotating assembly 3 includes a connecting seat 301, a round block 302, a mounting block 303, a fixing plate 304, a fitting ring 1 305 and a fitting ring 2 306. The connecting seat 301 is fixedly mounted on an outer wall of one side of the flaw detector 101, the round block 302 is rotatably mounted in the connecting seat 301, the mounting block 303 is fixedly mounted on an outer wall of one side of the round block 302, the fixing plate 304 is fixedly mounted on an outer wall of one side of the mounting block 303, and the fitting ring 1 305 is fixedly sleeved on the round block 302. The second fitting ring 306 is fixedly sleeved on the connecting seat 301, and the fixing plate 304 is fixedly connected to the rectangular plate 201. More specifically, when the flaw detector 101 is rotated, the flaw detector 101 drives the connecting seat 301 to rotate, and the connecting seat 301 rotates on the round block 302, and the connecting seat 301 drives the second fitting ring 306 to rotate. The second fitting ring 306 is fitted with the first fitting ring 305. The friction between the first fitting ring 305 and the second fitting ring 306 is relatively large and limits the flaw detector 101, so that the rotation viewing angle of the flaw detector 101 can be adjusted conveniently.

[0029] In addition, the fitting ring 1 305 and the fitting ring 2 306 are both made of rubber material, and semicircular blocks are distributed in an annular manner on the outer wall of one side of the fitting ring 1 305, and an annular groove is opened on the outer wall of one side of the fitting ring 2 306, and semicircular grooves are distributed in an annular manner on the inner wall of the annular groove, and the semicircular groove is adapted to the semicircular blocks, and the semicircular blocks are adapted to the annular groove. More specifically, the fitting ring 2 306 fits with the fitting ring 1 305 and rotates on the fitting ring 1 305. Since the fitting ring 1 305 and the fitting ring 2 306 are both made of rubber material, the friction between the fitting ring 1 305 and the fitting ring 2 306 is relatively large and limits the flaw detector 101, and the fitting ring 2 306 drives the annular groove and the semicircular groove to rotate, and the semicircular blocks slide in the annular groove. When the semicircular blocks are aligned with the semicircular groove, they sink into the semicircular groove and produce a sense of staggeredness to prompt the user, thereby facilitating adjustment of the limit.

[0030] Working principle:

[0031] Step 1: unfold the clamping device, the staff picks up the flaw detector 101, and then the staff pushes the clamp plate 206 upward, the clamp plate 206 drives the connecting block 204 to rotate, the connecting block 204 rotates and drives the torsion spring 205 to twist, the torsion spring 205 is deformed and accumulates elastic force due to the twisting, the connecting block 204 drives the rotating rod 203 to rotate, the clamp plate 206 flips and moves away from the clamp plate 207, the clamp plate 207 loses the obstruction of the clamp plate 206, and then the clamp plate 207 is pushed downward to flip, and the clamp plate 206 An opening is formed between the second clamp plate 207 and aligned with the steel structure, the first clamp plate 206 and the second clamp plate 207 are moved, and the steel structure is inserted between the first clamp plate 206 and the second clamp plate 207, and the first clamp plate 206 is loosened. The torsion spring 205 loses its torsional force and releases its elastic force to drive the first clamp plate 206 to reset. The first clamp plate 206 and the second clamp plate 207 clamp the steel structure. If the cross-section of the steel structure is small, the first clamp plate 206 is reset to fit the steel structure, and a triangular gap is formed between the second clamp plate 207 for hanging. At this time, the clamping and hanging are completed.

[0032] Step 2: Adjust and rotate. Rotate the flaw detector 101. The flaw detector 101 drives the connecting seat 301 to rotate. The connecting seat 301 rotates on the round block 302. The connecting seat 301 drives the second fitting ring 306 to rotate. The second fitting ring 306 fits with the first fitting ring 305. Since the first fitting ring 305 and the second fitting ring 306 are both made of rubber material, the friction between the first fitting ring 305 and the second fitting ring 306 is relatively large and limits the flaw detector 101. When the flaw detector 101 rotates to a suitable position, the adjustment and rotation is completed.
