Description

Technical Field

[0001] This invention belongs to the field of weld inspection technology, and particularly relates to a device and method for detecting defects in steel structure welds. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. After the steel columns and other components are welded, the welds are inspected to ensure the quality of the welds and to detect any defects that may affect the quality of the weld.

[0003] During the inspection of welds, because the welds between steel pipes are circumferential, workers need to rotate around the steel pipes to inspect them or rotate the steel pipes to inspect the welds. This requires a certain amount of physical strength and is inefficient, which will affect the overall efficiency. In addition, manual operation is more likely to cause errors. Summary of the Invention

[0015] As a further description of the above technical solution:

[0016] The support frame has a limiting strip on one side and a groove corresponding to the limiting strip on one side of the support rod. The fixing strap is made of flexible material.

[0017] As a further description of the above technical solution:

[0018] The vibration assembly includes a mounting frame, the bottom of which is fixedly connected to a base, and one side of which is fixedly connected to a support base. A slider is slidably mounted inside the mounting frame.

[0019] As a further description of the above technical solution:

[0020] The slider is rotatably fitted with a threaded sleeve through a slot at its top. A second threaded rod is internally threaded to the threaded sleeve. A striking ball is fixedly installed at the top of the second threaded rod. A spring is fixedly installed at the bottom of the slider. The bottom of the spring is fixedly connected to the base. A slot corresponding to the toggle block is provided on one side of the slider.

[0021] As a further description of the above technical solution:

[0022] The second threaded rod is slidably connected to the base through a through hole, and the second threaded rod is slidably connected to the slider through a through hole. The slider is provided with a limiting strip and the second threaded rod is provided with a corresponding groove.

[0023] This invention also discloses a method for using a steel structure weld defect detection device, comprising the following steps:

[0024] S1. When inspecting the steel pipe, remove the fixing rod to separate it from the support block, support rod, and support frame. Adjust the support block to a suitable height according to the size of the steel pipe. Then reinsert the fixing rod into the support block, support rod, and support frame. Pass the steel pipe between the fixing band and the support block and through the rotating ring. Rotate the first threaded rod to move the connecting block, which in turn moves the fixing band, bringing it into contact with the surface of the steel pipe.

[0025] S2. Simultaneously, as the connecting block gradually descends, the force between the fixing band and the steel pipe gradually increases, thereby ensuring the stability of the steel pipe fixing. Furthermore, since the support block is a V-shaped block, it can provide good support not only for square steel pipes but also for round steel pipes. At the same time, since the fixing band is made of flexible material, it can better fit with the surface of the steel pipe, thereby further ensuring the fixing of the steel pipe. After the steel pipe is fixed by the fixing components, the second threaded rod can be raised and lowered by rotating the threaded sleeve.

[0026] S3. The second threaded rod can move the striking ball by lifting and lowering, so that the top of the striking ball contacts the bottom of the steel pipe, thereby starting the motor to drive the reciprocating screw to rotate and drive the gear to rotate. The meshing between the gear and the gear ring drives the rotating ring to rotate in the mounting ring. The rotation of the rotating ring drives the mounting seat to rotate, thereby driving the detection module to rotate with the rotation of the rotating ring. Since the steel pipe is located inside the rotating ring, the detection module can rotate around the steel pipe without manual operation, thereby reducing the labor of workers and reducing the errors caused by manual operation, thus ensuring the accuracy of detection. During the rotation, the rotation of the reciprocating screw can drive the detection module to move left and right, so that the detection module can detect the weld in the steel pipe at different angles, thereby further ensuring the accuracy of weld detection.

[0027] S4. During the process of the motor driving the rotating ring to rotate, when the paddle slides through the groove on one side of the slider as the rotating ring rotates, the groove on the side of the slider is an inclined groove. During the process of the paddle sliding in the groove on the side of the slider, the slider can be pressed by the paddle to move the slider downward, and the spring is compressed. At the same time, the second threaded rod can be moved and the striking ball can be separated from the bottom end of the steel pipe. When the paddle slides out of the groove on the side of the slider, the striking ball is brought back into contact with the bottom end of the steel pipe under the action of the spring. The striking ball strikes the steel pipe, and the striking causes the steel pipe to vibrate and releases the stress at the weld. The detection module can then detect whether cracks have occurred.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In this invention, by incorporating a detection component, during detection, a steel pipe is passed through the interior of a rotating ring and fixed by a fixing component. A motor is then started, driving a reciprocating screw to rotate and in turn, driving a gear to rotate. The meshing between the gear and the gear ring causes the rotating ring to rotate within the mounting ring. This rotation of the rotating ring, in turn, causes the mounting base to rotate, thus rotating the detection module along with the rotating ring. Since the steel pipe is located inside the rotating ring, the detection module can rotate around the steel pipe, eliminating the need for manual operation. This reduces labor and errors caused by manual operation, ensuring detection accuracy. Furthermore, during rotation, the reciprocating screw causes the detection module to move left and right, thus improving the detection accuracy. The module can inspect welds in steel pipes from different angles, further ensuring the accuracy of weld inspection. With this design, when inspecting welds between steel pipes, the pipe is simply passed through a rotating ring and fixed by a fixing component. A motor drives a gear to rotate, which in turn rotates the rotating ring and the inspection module. This allows the inspection module to automatically rotate around the steel pipe, reducing manual operation and labor costs, and minimizing errors caused by manual operation. Furthermore, as the inspection module rotates around the steel pipe, the motor-driven gears also rotate a reciprocating screw, causing the module to swing left and right, allowing for inspection from different positions and further improving accuracy.

[0030] 2. In this invention, by setting a fixing component, when inspecting the steel pipe, the fixing rod is removed to separate it from the support block, support rod, and support frame. The support block is then adjusted to a suitable height according to the size of the steel pipe. The fixing rod is then reinserted into the support block, support rod, and support frame. The steel pipe is then passed between the fixing band and the support block, and through the rotating ring. Rotating the first threaded rod moves the connecting block, which in turn moves the fixing band, bringing it into contact with the surface of the steel pipe. As the connecting block gradually descends, the force between the fixing band and the steel pipe gradually increases, ensuring the stability of the steel pipe. Furthermore, because the support block is a V-shaped block, its… This design not only provides good support for square steel pipes but also for round steel pipes. Furthermore, the flexible material of the fixing band allows for better contact with the steel pipe surface, further ensuring its fixation. This design effectively secures the steel pipe, preventing excessive shaking during testing and minimizing its impact on the results. The height of the support block can also be adjusted during testing to ensure the steel pipe is roughly centered on the rotating ring, further reducing its influence on the results. The V-shaped support block and flexible fixing band work together to secure the steel pipe effectively.

[0031] 3. In this invention, by providing a vibration component, after the steel pipe is fixed by the fixing component, the second threaded rod can be raised and lowered by rotating the threaded sleeve. The raising and lowering of the second threaded rod can also move the striking ball, so that the top of the striking ball contacts the bottom of the steel pipe. During the process of the motor driving the rotating ring to rotate, when the paddle slides through the groove opened on one side of the slider as the rotating ring rotates, since the groove opened on one side of the slider is an inclined groove, the paddle can squeeze the slider during the sliding process, causing the slider to move downward. This compresses the spring and simultaneously drives the second threaded rod to move, causing the striking ball to contact the bottom of the steel pipe. The mechanism separates the components, and when the pusher slides out of the slot on one side of the slider, the spring causes the striking ball to re-engage with the bottom of the steel pipe. The striking ball then strikes the steel pipe, causing vibration and releasing stress at the weld. This allows the detection module to check for cracks. Through this design, as the rotating ring drives the detection module to rotate, the pusher compresses the spring, causing the striking ball to strike the steel pipe. This vibration releases stress in the steel pipe, and the detection module detects changes at the weld, further ensuring weld quality. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-8The present invention provides a technical solution: a steel structure weld defect detection device, including a base 1, a support seat 2 fixedly installed on the top surface of the base 1, a detection component 3 provided on the top surface of the support seat 2, a vibration component 5 provided on one side of the detection component 3, and a fixing component 4 provided on the top surface of the base 1.

[0044] The detection component 3 includes a mounting ring 39, a toothed ring 38 on one side of the mounting ring 39, a rotating ring 31 rotatably mounted inside the mounting ring 39, a mounting base 32 fixedly mounted on the inner wall of the rotating ring 31, a reciprocating screw 35 rotatably mounted on the mounting base 32 through a through hole therein, a gear 34 fixedly mounted on one end of the reciprocating screw 35, and the output shaft of a motor 33 fixedly mounted on the other end of the reciprocating screw 35, a detection module 36 threadedly connected to the outer wall of the reciprocating screw 35, a lever 37 fixedly mounted on the inner wall of the rotating ring 31, one side of the gear 34 meshing with the toothed ring 38, the detection module 36 slidingly connected to the mounting base 32 through a groove therein, one end of the motor 33 fixedly connected to the mounting base 32, and the bottom end of the mounting ring 39 fixedly connected to the support base 2.

[0045] The specific implementation is as follows: The steel pipe is passed through the interior of the rotating ring 31 and fixed by the fixing component 4. The motor 33 is then started to drive the reciprocating screw 35 to rotate, which in turn drives the gear 34 to rotate. The meshing between the gear 34 and the gear ring 38 causes the rotating ring 31 to rotate within the mounting ring 39. The rotation of the rotating ring 31 causes the mounting base 32 to rotate, which in turn causes the detection module 36 to rotate along with the rotating ring 31. Since the steel pipe is located inside the rotating ring 31, the detection module 36 can rotate around the steel pipe without manual operation, thus reducing labor and errors caused by manual operation, thereby ensuring the accuracy of the detection. During the rotation process, the rotation of the reciprocating screw 35 causes the detection module 36 to move left and right, allowing the detection module 36 to detect the weld in the steel pipe at different angles, further ensuring the accuracy of the weld detection.

[0046] The fixing component 4 includes a support block 47, with support rods 46 fixedly installed on both sides of the support block 47. A support frame 48 is slidably installed on the outer wall of the support rod 46. A mounting bracket 44 is fixedly installed on one side of the support rod 46. A first threaded rod 43 is rotatably installed on the mounting bracket 44 through a through hole at its top. A connecting block 42 is threadedly connected to the outer wall of the first threaded rod 43. A fixing strap 41 is fixedly installed on one end of the connecting block 42. The connecting block 42 is slidably connected to the mounting bracket 44 through a groove. A fixing rod 45 is slidably installed on the support rod 46 through a through hole. The fixing rod 45 is slidably connected to the support block 47 through a through hole at its bottom end. The fixing rod 45 is slidably connected to the support frame 48 through a through hole. The support frame 48 has multiple through holes. The bottom end of the support frame 48 is fixedly connected to the base 1. A limiting strip is provided on one side of the support frame 48, and a groove corresponding to the limiting strip is provided on one side of the support rod 46. The fixing strap 41 is made of flexible material.

[0047] The specific implementation is as follows: When inspecting the steel pipe, the fixing rod 45 is removed and separated from the support block 47, support rod 46, and support frame 48. The support block 47 is then adjusted to a suitable height according to the size of the steel pipe. The fixing rod 45 is then reinserted into the support block 47, support rod 46, and support frame 48. The steel pipe is then passed between the fixing band 41 and the support block 47 and through the rotating ring 31. The first threaded rod 43 is rotated to move the connecting block 42, which in turn moves the fixing band 41, bringing it into contact with the surface of the steel pipe. As the connecting block 42 gradually descends, the force between the fixing band 41 and the steel pipe gradually increases, ensuring the stability of the steel pipe. Since the support block 47 is a V-shaped block, it can provide good support for both square and round steel pipes. Furthermore, since the fixing band 41 is made of flexible material, it can better fit the surface of the steel pipe, further ensuring the fixation of the steel pipe.

[0048] The vibration assembly 5 includes a mounting frame 56, the bottom of which is fixedly connected to the base 1, and one side of which is fixedly connected to the support 2. A slider 51 is slidably mounted inside the mounting frame 56. A threaded sleeve 54 is rotatably mounted on the slider 51 through a groove at its top. A second threaded rod 53 is threadedly connected inside the threaded sleeve 54. A striking ball 52 is fixedly mounted at the top of the second threaded rod 53. A spring 55 is fixedly mounted at the bottom of the slider 51. The bottom of the spring 55 is fixedly connected to the base 1. A groove corresponding to the toggle block 37 is provided on one side of the slider 51. The second threaded rod 53 is slidably connected to the base 1 through a through hole. The second threaded rod 53 is slidably connected to the slider 51 through a through hole. A limiting strip is provided inside the slider 51, and a corresponding sliding groove is provided inside the second threaded rod 53.

[0049] The specific implementation is as follows: After the steel pipe is fixed by the fixing component 4, the second threaded rod 53 can be raised and lowered by rotating the threaded sleeve 54. The raising and lowering of the second threaded rod 53 can also move the striking ball 52, so that the top of the striking ball 52 contacts the bottom of the steel pipe. During the process of the motor 33 driving the rotating ring 31 to rotate, when the toggle block 37 slides through the groove opened on one side of the slider 51 as the rotating ring 31 rotates, the toggle block 37 slides within the groove opened on one side of the slider 51 because the groove opened on one side of the slider 51 is an inclined groove. During the process, the slider 51 is pressed by the push block 37, causing the slider 51 to move downwards. This compresses the spring 55 and drives the second threaded rod 53 to move, causing the striking ball 52 to separate from the bottom of the steel pipe. When the push block 37 slides out of the groove on one side of the slider 51, the striking ball 52 re-contacts the bottom of the steel pipe under the action of the spring 55. The striking ball 52 then strikes the steel pipe, causing it to vibrate and releasing the stress at the weld. The detection module 36 then detects whether cracks have occurred.

[0050] This invention also discloses a method for using a steel structure weld defect detection device, comprising the following steps:

[0051] S1. When inspecting the steel pipe, remove the fixing rod 45 to separate it from the support block 47, support rod 46, and support frame 48. Adjust the support block 47 to a suitable height according to the size of the steel pipe. Then reinsert the fixing rod 45 into the support block 47, support rod 46, and support frame 48. Pass the steel pipe between the fixing band 41 and the support block 47 and through the rotating ring 31. Rotate the first threaded rod 43 to drive the connecting block 42 to move. The connecting block 42 then drives the fixing band 41 to move, and the fixing band 41 comes into contact with the surface of the steel pipe.

[0052] S2. Simultaneously, as the connecting block 42 gradually descends, the force between the fixing band 41 and the steel pipe gradually increases, thereby ensuring the stability of the steel pipe fixing. Furthermore, since the support block 47 is a V-shaped block, it can provide good support not only for square steel pipes but also for round steel pipes. At the same time, since the fixing band 41 is a flexible material, it can better fit with the surface of the steel pipe, thereby further ensuring the fixing of the steel pipe. After the steel pipe is fixed by the fixing component 4, the second threaded rod 53 can be raised and lowered by rotating the threaded sleeve 54.

[0053] S3, and can drive the striking ball 52 to move by the lifting and lowering of the second threaded rod 53, so that the top of the striking ball 52 contacts the bottom of the steel pipe, thereby starting the motor 33 to drive the reciprocating screw 35 to rotate and drive the gear 34 to rotate, thereby driving the rotating ring 31 to rotate in the mounting ring 39 through the meshing between the gear 34 and the gear ring 38, and can drive the mounting base 32 to rotate through the rotation of the rotating ring 31, thereby driving the detection module 36 to rotate with the rotation of the rotating ring 31. Since the steel pipe is located inside the rotating ring 31, the detection module 36 can rotate around the steel pipe without manual operation, thereby reducing the labor of workers and reducing the errors caused by manual operation, thus ensuring the accuracy of detection. In addition, during the rotation process, the rotation of the reciprocating screw 35 can drive the detection module 36 to move left and right, thereby enabling the detection module 36 to detect the weld in the steel pipe at different angles, thereby further ensuring the accuracy of weld detection.

[0054] S4. During the process of the motor 33 driving the rotating ring 31 to rotate, when the toggle block 37 slides through the groove on one side of the slider 51 as the rotating ring 31 rotates, the groove on one side of the slider 51 is an inclined groove. During the process of the toggle block 37 sliding in the groove on one side of the slider 51, the slider 51 is pushed down by the toggle block 37, and the spring 55 is compressed. At the same time, the second threaded rod 53 is moved and the striking ball 52 is separated from the bottom end of the steel pipe. When the toggle block 37 slides out of the groove on one side of the slider 51, the striking ball 52 is brought back into contact with the bottom end of the steel pipe by the action of the spring 55. The striking ball 52 strikes the steel pipe, and the striking causes the steel pipe to vibrate and releases the stress at the weld. The detection module 36 then detects whether there is a crack.

[0055] Working principle: When inspecting the steel pipe, the fixing rod 45 is removed to separate it from the support block 47, support rod 46, and support frame 48. The support block 47 is then adjusted to a suitable height according to the size of the steel pipe. The fixing rod 45 is then reinserted into the support block 47, support rod 46, and support frame 48. The steel pipe is then passed between the fixing band 41 and the support block 47, and through the rotating ring 31. Rotating the first threaded rod 43 moves the connecting block 42, which in turn moves the fixing band 41, bringing it into contact with the steel pipe surface. As the connecting block 42 gradually descends, the force between the fixing band 41 and the steel pipe gradually increases, ensuring the stability of the steel pipe fixation. Furthermore, because the support block 47 is a V-shaped block, it can provide good support not only for square steel pipes but also for round steel pipes. Simultaneously, because the fixing band 41 is made of flexible material, it can better conform to the surface of the steel pipe, further ensuring the fixation of the steel pipe. After the steel pipe is fixed by the fixing component 4, the second threaded rod 53 can be raised and lowered by rotating the threaded sleeve 54. The raising and lowering of the second threaded rod 53 can also move the striking ball 52, causing the top of the striking ball 52 to contact the bottom of the steel pipe. This starts the motor 33, which drives the reciprocating screw 35 to rotate and the gear 34 to rotate. The meshing between the gear 34 and the gear ring 38 causes the rotating ring 31 to rotate within the mounting ring 39. The rotating ring 31 drives the mounting base 32 to rotate, which in turn drives the detection module 36 to rotate along with the rotating ring 31. Since the steel pipe is located inside the rotating ring 31, the detection module 36 can rotate around the steel pipe, eliminating the need for manual operation and reducing labor and errors caused by manual operation, thus ensuring the accuracy of the detection. During rotation, the reciprocating screw 35 drives the detection module 36 to move left and right, allowing it to detect the weld seam in the steel pipe at different angles, further ensuring the accuracy of the weld seam detection. Meanwhile, the motor 33 drives the rotating ring 31 to rotate... During the process, when the lever 37 slides through the groove on one side of the slider 51 as the rotating ring 31 rotates, the groove on the side of the slider 51 is an inclined groove. As the lever 37 slides within the groove, it compresses the slider 51, causing it to move downwards. This compresses the spring 55 and simultaneously moves the second threaded rod 53, separating the striking ball 52 from the bottom of the steel pipe. When the lever 37 slides out of the groove on the side of the slider 51, the spring 55 causes the striking ball 52 to re-engage with the bottom of the steel pipe, striking the pipe and causing vibration, thus releasing stress at the weld.Therefore, the detection module 36 can detect whether cracks have formed.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method of using a steel structure weld defect detection device according to any one of claims 1-9, characterized in that, Includes the following steps: S1. When inspecting the steel pipe, remove the fixing rod (45) to separate it from the support block (47), support rod (46), and support frame (48). Adjust the support block (47) to a suitable height according to the size of the steel pipe. Then reinsert the fixing rod (45) into the support block (47), support rod (46), and support frame (48). Pass the steel pipe between the fixing band (41) and the support block (47) and through the rotating ring (31). Rotate the first threaded rod (43) to drive the connecting block (42) to move. Then, drive the fixing band (41) to move through the connecting block (42) and make the fixing band (41) contact the surface of the steel pipe. S2. As the connecting block (42) gradually descends, the force between the fixing band (41) and the steel pipe gradually increases, thereby ensuring the stability of the steel pipe fixing. Since the support block (47) is a V-shaped block, it can not only provide good support for square steel pipes but also support round steel pipes. Since the fixing band (41) is a flexible material, it can better fit with the surface of the steel pipe, thereby further ensuring the fixing of the steel pipe. After the steel pipe is fixed by the fixing component (4), the second threaded rod (53) can be raised and lowered by rotating the threaded sleeve (54). S3, and can drive the striking ball (52) to move by the lifting and lowering of the second threaded rod (53), so that the top of the striking ball (52) contacts the bottom of the steel pipe, thereby starting the motor (33) to drive the reciprocating screw (35) to rotate and drive the gear (34) to rotate, thereby driving the rotating ring (31) to rotate in the mounting ring (39) through the meshing between the gear (34) and the gear ring (38), and can drive the mounting base (32) to rotate through the rotation of the rotating ring (31), thereby driving the detection module (36) to rotate with the rotation of the rotating ring (31). The steel pipe is located inside the rotating ring (31), which allows the detection module (36) to rotate around the steel pipe without the need for manual operation, thereby reducing the labor of workers and reducing the error caused by manual operation, thus ensuring the accuracy of the detection. During the rotation, the rotation of the reciprocating screw (35) can drive the detection module (36) to move left and right, so that the detection module (36) can detect the weld in the steel pipe at different angles, thereby further ensuring the accuracy of the weld detection. S4. During the process of the motor (33) driving the rotating ring (31) to rotate, when the push block (37) slides through the groove opened on one side of the slider (51) as the rotating ring (31) rotates, since the groove opened on one side of the slider (51) is an inclined groove, the push block (37) can squeeze the slider (51) by pressing it, causing the slider (51) to move downward and compressing the spring (55) at the same time. It can drive the second threaded rod (53) to move and cause the striking ball (52) to separate from the bottom of the steel pipe. When the push block (37) slides out from the groove opened on the side of the slider (51), the striking ball (52) will re-contact the bottom of the steel pipe under the action of the spring (55), thereby striking the steel pipe with the striking ball (52), thereby causing the steel pipe to vibrate and releasing the stress at the weld, thereby detecting whether there is a crack by the detection module (36).
