Description

Technical Field

[0001] The invention relates to the technical field of metal weld detection, in particular to a steel pipe weld rapid detection device. Background Art

[0002] The inspection of steel pipe welds is an important step to ensure the quality of welding. Through the inspection of steel pipe welds, the subsequent use of the welded steel pipe can be ensured. Fig.11 A bent steel pipe is shown, which has two welds. The bent steel pipe is composed of a 90-degree bend and two straight pipes. The two ends of the 90-degree bend are connected to the two straight pipes by welding. Since the weld position of the bent steel pipe is more than one, how to quickly and effectively detect the weld quality of the bent steel pipe needs to be solved urgently.

[0003] The actual method of inspecting this type of bent steel pipe is usually to use a clamping and positioning device to position and clamp the steel pipe, and then use a fixed position annular detection piece to detect the degree of concavity at the weld position of the steel pipe, so that the quality of the weld at the weld position is indicated according to the degree of concavity at the weld position. After one weld is inspected, the bent steel pipe is removed from the clamping and positioning device and rotated 90 degrees, and then the bent steel pipe is positioned and clamped again by the clamping and positioning device, and another weld position is inspected with the annular detection piece.

[0004] Although the above detection method can effectively detect the weld position of the bent steel pipe, it still has the following disadvantages: Disadvantage 1: The bent steel needs to be positioned twice during the above operation, but the secondary positioning operation is cumbersome and will increase the risk of deviation in the detection result due to inaccurate positioning; Disadvantage 2: During the welding process, the non-metallic substances in the welding material will be converted into welding slag. Although the presence of welding slag will not affect the quality of the weld, it will affect the degree of unevenness of the weld position, thereby resulting in inaccurate detection results when the weld quality detection of the weld position is performed.

DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0033] See also Figure 1 , Figure 2 and Fig.12 A steel pipe weld rapid detection device includes a detection area plate 1, a vertical plate 11 is fixed to the top rear end of the detection area plate 1, a longitudinal plate 12 is fixed to the top right end of the detection area plate 1, a rotating unit 2 is arranged on the front side of the vertical plate 11, two mutually perpendicular clamping units 3 are arranged in the middle of the rotating unit 2, a detection unit 4 is arranged in the middle of the longitudinal plate 12, and a power component 44 is arranged on the detection unit 4.

[0034] The present invention clamps the bent steel pipe to be inspected by the clamping unit 3, and quickly inspects the weld quality of the first weld position of the bent steel pipe by the inspection unit 4, and the bent steel pipe can be quickly rotated 90 degrees by the rotating unit 2, so that the second weld of the bent steel pipe is aligned with the inspection unit 4, and the weld quality of the second weld of the bent steel pipe is inspected by the inspection unit 4, thereby achieving the purpose of quickly inspecting the two welds on the bent steel pipe.

[0035] Specifically, the operator first installs and positions the bent steel pipe to be inspected through the clamping unit 3. After the installation is completed, the power component 44 drives the detection unit 4 to perform weld quality inspection on the first weld position of the positioned bent steel pipe. After the first weld position inspection of the bent steel pipe is completed, the rotation unit 2 is controlled to drive the clamping unit 3 and the bent steel pipe to rotate 90 degrees, and then the power component 44 is controlled again to drive the detection unit 4 to perform weld quality inspection on the second weld position of the rotated bent steel pipe.

[0036] See also Figure 1-Figure 2 The rotating unit 2 includes a motor 21 installed on the front side of the vertical plate 11 through a motor box. A rotating disk 211 is installed at the output end of the motor 21. The rotating disk 211 consists of a central circle part and a fan-shaped part. An arc-shaped slider 212 is fixed to the side of the fan-shaped part of the rotating disk 211. A stable slide groove 213 matching the arc-shaped slider 212 is fixed to the left side of the longitudinal plate 12 and at the position corresponding to the rotating disk 211.

[0037] The rotating unit 2 is used to drive the bent steel pipe to rotate 90 degrees after the weld quality inspection of the first weld of the bent steel pipe is completed, so that the other weld can quickly reach the inspection position, thereby eliminating the steps of repeated installation and positioning during the inspection of the two weld positions, making the inspection operation simple and avoiding the occurrence of inaccurate inspection results due to repeated positioning.

[0038] Specifically, after the power component 44 drives the detection unit 4 to complete the weld quality inspection on the first weld position of the bent steel pipe that has been positioned, the No. 1 motor 21 is controlled to drive the rotating disk 211 to rotate, so that the clamping unit 3 rotates together with the bent steel pipe, and when the bent steel pipe rotates to 90 degrees, the No. 1 motor 21 is stopped, and at this time, the second weld position of the bent steel pipe just rotates to the position of the detection unit 4.

[0039] It should be noted that since the clamping position of the clamping unit 3 cannot overlap with the position of the weld to be inspected on the bent steel pipe, the rotation point of the rotating disk 211 should be located at the lower right of the intersection of the two straight lines where the two clamping units 3 are located, that is, the connection point between the output end of motor No. 1 21 and the rotating disk 211 should be located at the lower right of the intersection of the two straight lines where the two clamping units 3 are located.

[0040] See also Figure 3 and Figure 5 The clamping unit 3 includes a longitudinal through hole 31 fixedly opened in the middle of the fan-shaped part of the rotating disk 211, each longitudinal through hole 31 is slidably connected with a sliding block 311, and the front ends of the two sliding blocks 311 are fixed with clamping elements 32 for cooperating with each other to position the steel pipe through front extension columns 312. A synchronous adjustment element 33 is arranged in the fan-shaped part of the rotating disk 211 and at the position of the symmetry axis of the two clamping elements 32.

[0041] See also Figure 3 , Figure 5 and Figure 6 The clamping element 32 includes a fixed clamping plate 321 fixed to the front end of the front extension column 312, a limiting rod 322 is fixed to the side of the front end of the fixed clamping plate 321 close to the No. 1 motor 21, a stud 323 is rotatably installed on the side of the front end of the fixed clamping plate 321 away from the No. 1 motor 21, a movable clamping plate 324 is commonly connected to the limiting rod 322 and the stud 323, and an internal clamping structure is provided on the opposite sides of the movable clamping plate 324 and the fixed clamping plate 321; the internal clamping structure includes limiting pins 325 slidably connected to both sides of the fixed clamping plate 321 with the front extension column 312 as the axis, a longitudinal spring is connected between the end of the limiting pin 325 close to the front extension column 312 and the fixed clamping plate 321, and an inner clamping plate 326 is commonly fixed to the front ends of the two limiting pins 325.

[0042] The clamping unit 3 is used to position and clamp the bent steel pipe with the clamping element 32, so that the center position of the circle where the 90-degree bend of the bent steel pipe is located coincides with the position of the output end of the No. 1 motor 21, so that after the rotating unit 2 drives the bent steel pipe to rotate 90 degrees, the second weld position of the bent steel pipe can be automatically aligned with the position of the detection unit 4. The bent steel pipe is clamped and positioned by a combination of the inner clamp 326, the fixed clamp 321 and the movable clamp 324, which can increase the stability of the bent steel pipe when the detection unit 4 detects the bent steel pipe, thereby ensuring the accuracy of the weld quality detection results.

[0043] Specifically, the operator first inserts the bent steel pipe into the two clamping elements 32 in sequence. After the bent steel pipe is inserted, the synchronous adjustment element 33 is controlled to synchronously adjust the position of the two clamping elements 32, so that the center position of the circle where the 90-degree bend of the bent steel pipe is located coincides with the position of the output end of the No. 1 motor 21. Then, the operator manually turns the stud 323 to move the movable clamp 324 toward the fixed clamp 321. During the movement of the movable clamp 324, the two inner clamps 326 will simultaneously clamp the straight pipe part of the bent steel pipe and complete the positioning of the bent steel pipe.

[0044] See also Figure 3-Figure 5The synchronous adjustment element 33 includes an oblique through groove 331 opened in the fan-shaped part of the rotating disk 211, and an oblique slider 332 is slidably connected in the oblique through groove 331. A connecting rod 333 is fixed to the rear end of the oblique slider 332. A telescopic rod 334 is fixed between the rear end of the connecting rod 333 and the rear end of each sliding block 311, and a positioning hole 335 is provided on the oblique slider 332; the fan-shaped part of the rotating disk 211 is provided with evenly distributed matching holes 336, and a positioning pin is connected between the positioning hole 335 and the matching hole 336 at the corresponding position.

[0045] The synchronous adjustment element 33 is used to synchronously adjust the positions of the two clamping elements 32, so as to ensure that after the clamping element 32 completes the positioning of the bent steel pipe, the center position of the circle where the 90-degree bend of the bent steel pipe is located coincides with the position of the output end of the No. 1 motor 21, so that the clamping element 32 can adapt to the bent steel pipes of different sizes and position them. At the same time, after the position adjustment of the synchronous adjustment element 33 is completed, the position of the oblique slider 332 is positioned by the positioning pin, which can further ensure the stability of the clamping positioning of the two clamping elements 32 by stabilizing the position of the clamping element 32.

[0046] Specifically, after the operator inserts the bent steel pipe into the two clamping elements 32 in sequence, the oblique slider 332 is controlled to slide in the oblique through groove 331 according to the size of the bent steel pipe. At this time, as the telescopic rod 334 is extended and retracted, the oblique slider 332 will drive the two sliding blocks 311 to move synchronously, so that the center position of the circle where the 90-degree bend of the bent steel pipe is located coincides with the position of the output end of the No. 1 motor 21. After the position adjustment of the clamping element 32 and the bent steel pipe is completed, the positioning pin is inserted into the positioning hole 335 and the matching hole 336 at the corresponding position to fix the position of the oblique slider 332 and the sliding block 311.

[0047] In the process of positioning the bent steel pipe, the method of inserting the bent steel pipe first and then adjusting the two clamping elements 32 can facilitate the insertion of the bent steel pipe. If the positions of the two clamping elements 32 are adjusted first, the subsequent operation of inserting the bent steel pipe will be more difficult.

[0048] See also Figure 7-Figure 8The detection unit 4 includes a horizontal through slot 41 opened in the middle of the longitudinal plate 12, a longitudinal moving block 411 is longitudinally slidably connected in the middle of the horizontal through slot 41, a threaded rod 412 is rotatably installed at the front end of the longitudinal moving block 411, the front end of the threaded rod 412 passes through the longitudinal plate 12 and is fixed with a crank, the threaded rod 412 is threadedly connected to the longitudinal plate 12, a rotating ring 418 is slidably connected to the left side of the longitudinal moving block 411 through a limiting structure, and a welding slag cleaning element 42 and a weld detection element 43 are respectively arranged on the left and right sides of the rotating ring 418; the limiting structure includes a cylinder 413 installed on the left side of the longitudinal moving block 411, a limiting slider 414 is fixed to the pushing end of the cylinder 413, an L-shaped extension rod 415 is fixed to the left side of the rear end of the longitudinal moving block 411, a sliding sleeve 416 is sleeved on the left end of the horizontal section of the L-shaped extension rod 415, a matching slider 417 is fixed to the left end of the front side of the sliding sleeve 416, and the matching slider 417 and the limiting slider 414 are slidably connected to the rotating ring 418.

[0049] The detection unit 4 is used to detect the weld quality of two weld positions of the bent steel pipe, wherein the weld detection element 43 can detect the weld quality of the weld position, and the weld slag cleaning element 42 can clean the loose weld slag generated during the welding process, thereby avoiding the influence of the weld slag on the weld quality detection result and ensuring the use of the steel pipe after the detection is completed. At the same time, the rotating ring 418 drives the weld slag cleaning element 42 and the weld detection element 43 to rotate for cleaning and detection, thereby ensuring the comprehensiveness of the cleaning of the weld slag cleaning element 42 and the accuracy of the detection result completed by the weld detection element 43.

[0050] Specifically, before inspecting the bent steel pipe, it is necessary to adjust the position of the rotating ring 418 by the cylinder 413 and the threaded rod 412. According to the size of the bent steel pipe, the threaded rod 412 is first rotated by the crank to adjust the front and rear position of the longitudinal moving block 411. Then, the cylinder 413 pushes the limit slider 414 to the left and cooperates with the freely retractable matching slider 417 to adjust the left and right position of the rotating ring 418, so that the welding slag cleaning element 42 and the weld detection element 43 can adjust the weld position of the bent steel pipe. When the clamping element 32 completes clamping the bent steel pipe, the control power component 44 drives the rotating ring 418 to rotate. As the rotating ring 418 rotates, the welding slag cleaning element 42 and the weld detection element 43 will rotate together and clean the weld position of the bent steel pipe and detect the weld quality of the weld position.

[0051] Continue reading Figure 7-Figure 8The power assembly 44 includes a second motor 441 installed on the rear side of the sliding sleeve 416 through a motor box, and a power gear 442 is fixed to the output end of the second motor 441; a synchronization ring 419 is fixed to the bottom of the rotating ring 418, and a plurality of tooth-shaped protrusions 443 for meshing with the power gear 442 are evenly arranged on the side of the synchronization ring 419. The power assembly 44 is used to drive the rotating ring 418 to rotate

[0052] The power assembly 44 is used to simultaneously drive the welding slag cleaning element 42 and the weld detection element 43 to rotate, so as to clean the welding slag and detect the weld quality of the bent steel pipe. The synchronous ring 419 is mainly used to drive the rotating ring 418 to rotate. Specifically, when the clamping element 32 completes the clamping of the bent steel pipe, the second motor 441 is controlled to drive the power gear 442 to rotate. As the power gear 442 rotates, the power gear 442 will drive the synchronous ring 419 and the rotating ring 418 to rotate through the toothed protrusion 443, so that the welding slag cleaning element 42 and the weld detection element 43 installed on the rotating ring 418 can rotate along the weld of the bent steel pipe.

[0053] Continue reading Figure 7-Figure 8 The welding slag cleaning element 42 includes an adjustment structure arranged on the inner ring surface of the rotating ring 418, and the adjustment structure includes an outer frame 421 fixed on the inner ring surface of the rotating ring 418, and an embedded rod 422 is slidably connected in the outer frame 421, and a movable plate 423 is fixed on the top of the embedded rod 422; a positioning plate 424 is fixed at a position corresponding to the outer frame 421 on the top of the rotating ring 418, and an adjustment screw 425 is threadedly connected to the middle of the positioning plate 424, and one end of the adjustment screw 425 located in the rotating ring 418 is rotatably mounted on the movable plate 423; the welding slag cleaning element 42 also includes a collection block fixed at one end of the embedded rod 422 away from the outer frame 421 426, a rotating plate 427 is hingedly connected to the front end of the assembly block 426, a torsion spring is arranged at the hinge position of the rotating plate 427 and the assembly block 426, a pressing protrusion 428 and a pointed scraper 429 are fixed in sequence from back to front on the side of the rotating plate 427 close to the center of the rotating ring 418, a locking plate 450 is fixed to the rear side of the assembly block 426, a knocking nail 451 parallel to the embedded rod 422 is arranged through the locking plate 450, a tension spring is connected between the knocking nail 451 and the locking plate 450, a push rod 452 is fixed on the top of the knocking nail 451; an arc-shaped pushing plate 453 for pushing the pushed rod 452 is fixed on the top of the limiting structure.

[0054] The welding slag cleaning element 42 is used to remove the welding slag at the welding position of the bent steel pipe, so as to prevent the welding slag at the welding position of the bent steel pipe from affecting the process of weld quality inspection, thereby avoiding the occurrence of deviations in the inspection results due to the influence of welding slag. At the same time, the arc-shaped pushing plate 453 and the pushed rod 452 cooperate to allow the knocking pin 451 to knock the welding position of the bent steel pipe for multiple times, so that the welding slag at the welding position of the bent steel pipe is loosened and easy to clean, thereby ensuring the cleaning effect of the welding slag cleaning element 42. In addition, the position of the welding slag cleaning element 42 can be accurately adjusted through the adjustment function of the adjustment structure, so that the welding slag cleaning element 42 can comprehensively and effectively clean the welding slag at the welding position of the bent steel pipe.

[0055] Specifically, after the position adjustment of the rotating ring 418 is completed by the cylinder 413 and the threaded rod 412, the operator rotates the adjusting screw 425 to move the movable plate 423 and the positioning plate 424 together, thereby adjusting the position of the embedded rod 422 relative to the bent steel pipe, and making the knocking nail 451, the pressing protrusion 428 and the pointed scraper 429 press against the side of the weld position of the bent steel pipe. When the power component 44 drives the rotating ring 418 to rotate, the pushed rod 452 will be pushed away from the side of the weld position of the bent steel pipe by the arc-shaped pushing plate 453. When the pushed rod 452 is separated from the arc-shaped pushing plate 453, the knocking nail 451 will knock on the side of the weld position of the bent steel pipe due to the elastic force of the tension spring, thereby separating the relatively loose welding slag at the weld position of the bent steel pipe from the weld and facilitating subsequent cleaning.

[0056] Then the pressing protrusion 428 and the pointed scraper 429 will successively press against the side of the weld position of the bent steel pipe. During this process, the pointed scraper 429 will scrape off the welding slag that has been completely loosened due to the knocking. When encountering harder welding slag, the pressing protrusion 428 will be pressed by the hard welding slag, and the pointed scraper 429 will be driven away from the hard welding slag through the rotating plate 427. After leaving the hard welding slag, the pressing protrusion 428 will return to its original position together with the pointed scraper 429.

[0057] See also Figure 8-Figure 10The weld detection element 43 includes an adjustment structure arranged on the inner ring surface of the rotating ring 418 and located on the opposite side of the welding slag cleaning element 42. A pressure rod 431 is slidably connected in the inner rod 422. Square plates 432 are fixed on both the front and rear sides of the pressure rod 431. An avoidance groove for avoiding the square plate 432 is arranged in the inner rod 422. An inner spring is connected between the square plate 432 and the avoidance groove; a lower slot is arranged at the bottom of the inner rod 422, and a horizontal rod 433 is arranged in the lower slot. The horizontal rod 433 is symmetrical on the left and right. A horizontal slide plate 434 is slidably connected, a horizontal spring is connected between the horizontal slide plate 434 and the lower slotted side, a horizontal push plate 435 slidably connected to the horizontal rod 433 is fixed to the top of the pressure rod 431, and mounting blocks 436 are symmetrically fixed on the left and right sides of the horizontal push plate 435 at the bottom of the embedded rod 422, each mounting block 436 is fixed with a button 437 on the side close to the horizontal slide plate 434, and an indicator light 438 controlled by the button 437 is fixed to the bottom of each mounting block 436.

[0058] The weld detection element 43 is used to detect the degree of weld convexity at the weld position of the bent steel pipe, thereby indirectly indicating the weld quality at the weld position of the bent steel pipe according to the degree of weld convexity at the weld position of the bent steel pipe. Specifically, after the position adjustment of the rotating ring 418 is completed by the cylinder 413 and the threaded rod 412, the position of the weld detection element 43 is adjusted in the same manner as the above-mentioned operation adjustment structure, so that the pressure rod 431 is pressed against the side of the weld position of the bent steel pipe, and the pressure rod 431 continues to compress the inner spring. As the weld detection element 43 continues to rotate along the side of the weld position of the bent steel pipe, the pressure rod 431 will be pressed against the side of the weld position of the bent steel pipe, and the movement of the pressure rod 431 is controlled by the degree of concave-convexity of the weld position.

[0059] When the weld position is too concave, the compression rod 431 will drive the horizontal push plate 435 to press against the horizontal slide 434 due to the elastic force of the internal spring, and the horizontal slide 434 will push the button 437, and the indicator light 438 controlled by the button 437 will change from the initial green to red. When the weld position is too convex, the weld position will press against the compression rod 431 and drive the horizontal push plate 435 to press against the horizontal slide 434, and the horizontal slide 434 will push the button 437, and the indicator light 438 controlled by the button 437 will change from the initial green to red. Therefore, during the detection process, if the two indicator lights 438 turn red at some point, the quality of the weld position of the surface bent steel pipe is poor. If during the detection process, if the two indicator lights 438 are both green, the quality of the weld position of the surface bent steel pipe is qualified.

[0060] The working steps of the present invention are as follows: In the first step, the operator first inserts the bent steel pipe into the two clamping elements 32 in sequence. After the bent steel pipe is inserted, the synchronous adjustment element 33 is controlled to synchronously adjust the position of the two clamping elements 32, so that the center position of the circle where the 90-degree bend of the bent steel pipe is located coincides with the position of the output end of the No. 1 motor 21. Then, the operator manually rotates the stud 323 to move the movable clamp 324 toward the fixed clamp 321. During the movement of the movable clamp 324, the two inner clamps 326 will simultaneously clamp the straight pipe part of the bent steel pipe and complete the positioning of the bent steel pipe.

[0061] In the second step, after the inner clamping plate 326 has clamped the bent steel pipe, the front and rear positions of the longitudinal moving block 411 are adjusted by first rotating the threaded rod 412 by the crank according to the size of the bent steel pipe, and then the limiting slider 414 is pushed to the left by the cylinder 413 and the left and right positions of the rotating ring 418 are adjusted in cooperation with the freely retractable matching slider 417, and then the positions of the weld detection element 43 and the weld slag cleaning element 42 are adjusted by the adjustment structure.

[0062] In the third step, after the position adjustment of the weld detection element 43 and the weld slag cleaning element 42 is completed through the adjustment structure, the control power component 44 drives the rotating ring 418 to rotate. At this time, the weld slag cleaning element 42 and the weld detection element 43 will rotate together. During the rotation of the weld slag cleaning element 42, the push rod 452 will cooperate with the arc-shaped pushing plate 453 to drive the knocking nail 451 to knock on the side of the bent steel pipe weld position, and then the pressing protrusion 428 and the pointed scraper 429 will successively press against the side of the bent steel pipe weld position. In this process, the pointed scraper 429 will scrape off the weld slag that was completely loosened due to the knocking. When encountering harder weld slag, the pressing protrusion 428 will be pressed by the hard weld slag and drive the pointed scraper 429 away from the hard weld slag through the rotating plate 427. When separated from the hard weld slag, the pressing protrusion 428 will return to its original position together with the pointed scraper 429.

[0063] In the fourth step, when the weld detection element 43 rotates with the rotating ring 418, the weld detection element 43 can detect the degree of weld convexity at the weld position of the bent steel pipe, thereby indirectly indicating the weld quality of the weld position of the bent steel pipe according to the degree of weld convexity at the weld position of the bent steel pipe. When the inner concavity or outer convexity of the weld position is too large, the pressure rod 431 will drive the horizontal push plate 435 to press the horizontal slide plate 434 due to the elastic force of the inner spring or directly under the pressure of the weld position. The horizontal slide plate 434 will push the button 437, and the button 437 will control the indicator light 438 to change from the initial green to red. Therefore, during the detection process, if the two indicator lights 438 turn red at some point, the quality of the weld position of the surface bent steel pipe is poor. If during the detection process, if the two indicator lights 438 are both green, the quality of the weld position of the surface bent steel pipe is qualified.

[0064] The fifth step is that after the power component 44 drives the detection unit 4 to complete the weld quality inspection on the first weld position of the bent steel pipe that has been positioned, the No. 1 motor 21 is controlled to drive the rotating disk 211 to rotate counterclockwise, so that the clamping unit 3 rotates together with the bent steel pipe, and when the bent steel pipe rotates to 90 degrees, the No. 1 motor 21 is stopped. At this time, the second weld position of the bent steel pipe just rotates to the position of the detection unit 4, and then the above-mentioned detection operation is repeated and the second weld position of the bent steel pipe is quickly detected.
