These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0027] According to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or regarded as a limitation or restriction on the technical solution of the present utility model.

[0028] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Embodiment 1, as Figure 1 、 Figure 2 、 Figure 8 shown, a transverse magnetic flux leakage detection device for automatically adjusting the steel pipe model, the steel pipe passes through the middle of the device, and the device performs transverse magnetic flux leakage detection on the steel pipe. The device includes a frame 1, an upper magnetic shoe changing mechanism 2, a lower magnetic shoe changing mechanism 3, and a probe changing mechanism 4. The upper magnetic shoe changing mechanism 2 is installed on the top of the frame 1, and an upper magnetic shoe 22 movably connected to the frame 1 is installed in the upper magnetic shoe changing mechanism 2. The lower magnetic shoe changing mechanism 3 is installed at the bottom of the frame 1, and a lower magnetic shoe 32 movably connected to the frame 1 is installed in the lower magnetic shoe changing mechanism 3.

[0030] The upper magnetic shoe 22 and the lower magnetic shoe 32 are respectively arranged on the upper and lower sides of the transverse magnetic leakage detection device. By adjusting the distance up and down, it is convenient to adapt to steel pipes of different models. Since the resolution of magnetic flux leakage testing has a great relationship with the magnetization direction, when detecting steel pipes, the two magnetic shoes magnetize the steel pipe sufficiently to reach the saturation state, improving the accuracy of magnetic flux leakage detection.

[0031] The probe conversion mechanism 4 is used to adjust the distance between the probe 55 and the steel pipe. By adjusting the distance left and right from the steel pipe to be detected, it is convenient to adapt to steel pipes of different models. The probe conversion mechanism 4 is installed on both sides of the frame body 1. The top of the probe conversion mechanism 4 is movably connected with a probe opening and closing mechanism 5. The working end of the probe opening and closing mechanism 5 is installed with a probe 55. The probe opening and closing mechanism 5 is used to press the probe 55 against the outer wall of the steel pipe for transverse magnetic flux leakage detection.

[0032] Among them, the frame body 1 includes a bottom plate 11 and a top plate 12. The four ends of the bottom plate 11 are fixedly connected to the top plate 12 through support columns. The working end of the upper magnetic shoe conversion mechanism 2 is installed on the top plate 12, and the working end of the lower magnetic shoe conversion mechanism 3 is installed on the bottom plate 11. A guiding ring 13 for the steel pipe to pass through is also provided at the feeding end of the frame body 1, and a guiding ring 13 can also be set at the discharging end. Please refer to Figure 8 , the steel pipe to be detected enters this equipment through the guiding ring 13, and then the steel pipe after detection can also be conveyed to the longitudinal magnetic flux leakage detection equipment through the guiding ring 13.

[0033] Example 2, please refer to Figure 3 and Figure 4 , on the basis of Example 1, the upper magnetic shoe conversion mechanism 2 includes an upper magnetizing coil 21, an upper magnetic shoe 22, and a first servo motor 23. The upper magnetizing coil 21 is installed at the bottom of the top plate 12. After passing through the upper magnetizing coil 21, the working end of the upper magnetic shoe 22 is set downward. The first servo motor 23 is installed on the top of the top plate 12 and its working end is in driving connection with the upper magnetic shoe 22 in the vertical direction. A lead screw nut mechanism can be set at the driving end of the first servo motor 23 to drive the upper magnetic shoe 22 to move longitudinally. The simplest way is to use a cylinder to replace the first servo motor 23 to drive the upper magnetic shoe 22, but the cylinder needs to be installed at the bottom of the top plate 12, and the setting of the rest of the connection structure is conventional technology. For example, the working end of the cylinder is set downward, and when the telescopic rod of the cylinder retracts, it drives the upper magnetic shoe 22 to rise, and when it extends, it drives the upper magnetic shoe 22 to fall.

[0034] Among them, the upper magnetizing coil 21 includes a first box body and a first coil installed in the first box body. The first coil surrounds the outer peripheral surface of the upper magnetic shoe 22 to facilitate magnetizing the upper magnetic shoe 22. A fan 38 communicating with the inside is installed on the outside of the first box body for dissipating heat for the first coil when it is working.

[0035] The lower magnetic shoe replacement mechanism 3 includes a lower magnetizing coil 31, a lower magnetic shoe 32, a second servo motor 33, and a lead screw nut mechanism. The lower magnetizing coil 31 is installed on the top of the bottom plate 11. The lower magnetic shoe 32 passes through the lower magnetizing coil 31 and its working end is set upward. The second servo motor 33 is installed on the top of the top plate 12 and is in driving connection with the lower magnetic shoe 32 in the vertical direction through the lead screw nut mechanism. Among them, the lower magnetizing coil 31 includes a second box body and a second coil installed in the second box body. The second coil surrounds the outer peripheral surface of the lower magnetic shoe 32 to facilitate magnetizing the lower magnetic shoe 32. A fan 38 communicating with the inside is installed on the outside of the second box body to dissipate heat for the second coil during operation.

[0036] In addition, arc-shaped grooves 37 are respectively provided at the working ends of the upper magnetic shoe 22 and the lower magnetic shoe 32. The two arc-shaped grooves 37 are symmetrical arc-shaped structures for matching the outer wall of the steel pipe to be detected conveyed.

[0037] Among them, the lead screw nut mechanism includes a transmission lead screw 34, a support plate 35, and a lead screw nut 36. This lead screw nut mechanism is only applicable to the lower magnetic shoe replacement mechanism 3 and can also provide a reference for the transmission movement of the upper magnetic shoe replacement mechanism 2. The top of the transmission lead screw 34 is in driving connection with the working end of the second servo motor 33. The transmission lead screw 34 is rotationally connected with the lead screw nut 36. The lead screw nut 36 is fixedly connected with the support plate 35. The lower magnetic shoe 32 is installed on the top of the support plate 35.

[0038] As a preferred solution, two guide posts 14 are installed on the bottom plate 11. Limit blocks are provided at the tops of the two guide posts 14. The two guide posts 14 are respectively sleeved with guide sleeves 15 slidably connected thereto. The guide sleeves 15 are fixedly connected to both sides of the support plate 35. Driven by the second servo motor 33, the transmission lead screw 34 rotates, thereby driving the lead screw nut 36 and the support plate 35 to move up and down under the guidance of the guide sleeves 15, and thus the distance between the lower magnetic shoe 32 and the steel pipe to be detected can be adjusted.

[0039] Example 3, please refer to Figures 5 to 7 , on the basis of Example 1, the probe replacement mechanism 4 includes a bracket 41, a third servo motor 42, and a cam disc 43. The bracket 41 is installed on the frame body 1. The third servo motor 42 is installed on the bracket 41. The output end of the third servo motor 42 is fixedly connected with the cam disc 43. The third servo motor 42 is in driving connection with the probe opening and closing mechanism 5 through the cam disc 43. Driven by the third servo motor 42, the cam disc 43 rotates. Since the center of the cam disc 43 is asymmetric and belongs to an eccentric wheel, when it contacts the probe opening and closing mechanism 5, it can convey the probe opening and closing mechanism 5 back and forth for a certain distance, and thus adjust the distance between the probe 55 in the probe opening and closing mechanism 5 and the steel pipe.

[0040] Specifically, in this solution, a walking guide groove 44 is provided inside the cam disc 43, and the walking guide groove 44 is an arc-shaped ring structure. A follower 45 is provided inside the walking guide groove 44 to move along the walking guide groove 44. A base 47 is installed at the bottom of the probe opening and closing mechanism 5, and the follower 45 and the base 47 are rotatably connected with the axis of the follower 45 as the rotation center. A linear guide rail 46 slidably connected to the bracket 41 is also installed at the bottom of the base 47, which plays a guiding role when driving the probe opening and closing mechanism 5 to move.

[0041] The walking guide groove 44 is an arc-shaped ring structure and a diffuse structure. The follower 45 has an eccentric effect along the position of the walking guide groove 44 and plays an eccentric motion mode like a cam, thereby driving the probe opening and closing mechanism 5 to move a certain distance.

[0042] During implementation, the probe opening and closing mechanism 5 includes a connecting rod group 51 and a fourth servo motor 52. The fourth servo motor 52 is mounted on the base 47. The output end of the fourth servo motor 52 is connected to the probe 55 through the connecting rod group 51. The probe group 56 is installed inside the probe 55. Driven by the fourth servo motor 52, the connecting rod group 51 moves forward, and the probe 55 can be pressed against the outer wall of the steel pipe, thereby detecting the magnetic flux leakage.

[0043] As a preferred solution, the connecting rod group 51 includes a support rod 53, a hinge plate 54, and a connecting plate 57. Two connecting plates 57 are provided, and one end of each connecting plate 57 is fixedly connected to the base 47. The other end of the connecting plate 57 is rotatably connected to the support rod 53. The hinge plate 54 is fixed to the middle of the support rod 53. One end of the hinge plate 54 is transmission-connected to the output end of the fourth servo motor 52, and the other end of the hinge plate 54 is fixedly connected to the probe 55. Such a setting utilizes the principle of lever. One side of the hinge plate 54 is subjected to force, while the other side moves in the opposite direction. The support rod 53 acts as a fulcrum. Therefore, the probe 55 can be attached more closely to the outer wall of the steel pipe by utilizing the principle of lever. A probe group 56 is installed inside the probe 55. The probes 55 in the probe group 56 are in a straight line, so that a one-time magnetic leakage detection can be performed on the steel pipe over a long distance.

[0044] In the equipment of this scheme, the upper and lower coils and magnetic shoes are used for magnetization, so that a probe 55 can be arranged on each side, and the spiral advance pitch of the steel pipe detection will be doubled. In actual work, the detection pitch can reach 300mm (the pipe advances 300 and rotates one circle. If it is greater than 300, it will cause missed detection), which greatly increases the detection efficiency. When changing the model, as long as the set model parameters are entered on the PLC screen, the upper and lower magnetic shoes and the position of the left and right probes can be controlled by the corresponding servo motor to achieve one-key model change.

[0045] Furthermore, the magnetic shoes can be driven in the up and down direction by a servo motor and a lead screw nut mechanism. For the two probes 55 on the left and right, a servo motor controls the cam disc 43, and the cam follower 45 drives the detection probe 55 to move in the horizontal direction. The tool change can be controlled by a servo motor to achieve one-key tool change. Guide rings 13 are installed at the inlet and outlet of the transverse magnetization detection host, which can protect the probe structure to the greatest extent.

[0046] In summary, this transverse magnetic flux leakage detection device not only has a high degree of automation, but also has high detection accuracy and efficiency. This makes this case have a significant improvement in operability and economy compared with the existing technologies, surpassing similar devices at home and abroad.
