[0049] The present embodiment further includes a side block 28, a front guide block 29 and a rear limit block 30. The side block 28 is connected to the connecting shell 2 and is located on one side of the connecting shell 2, and the side block 28 is located between the front hook 7 and the rear hook 8. The side block 28 is made of soft material. The side block 28 is used to fit with the support plate to maintain the stability of the device when the rotor toggling device toggles the rotor. The middle part of the rear hook 8 is rotatably connected to the side block 28, and the other end of the rear hook 8 is hinged to one end of the connecting rod 39; the front guide block 29 is connected to the connecting shell 2 and is located on one side of the connecting shell 2, the front guide block 29 is located in front of the front hook 7, and the front end face of the front guide block 29 is an inclined surface; the rear limit block 30 is located behind the rear hook 8, and when the rotor toggling device moves into place, the rear limit block 30 restricts the rotor toggling device from moving forward.

[0050] In this embodiment, the middle part of the front hook 7 is rotatably connected to the connecting shell 2 through a pin shaft 31, and the other end of the front hook 7 is hinged to the other end of the connecting rod 39. A torsion spring 32 is sleeved on the pin shaft 31, and one end of the torsion spring 32 is against the clamping shell, and the other end of the torsion spring 32 is in contact with the front hook 7. The torsion spring 32 ensures that the front hook 7 remains in an open state without being subjected to external force.

[0051] In this embodiment, the front guide block 29, the side block 28, the rear limit block 30, one end of the front hook 7 and one end of the rear hook 8 are all located on the same side of the connection housing 2.

[0052] In this embodiment, the locking structure includes a spring 21, a rotating shaft 18, a top block 19 and an electromagnet 20. The rotating shaft 18 and the electromagnet 20 are respectively connected to the connecting shell 2. The rotating shaft 18 passes through the middle of the top block 19. One end of the top block 19 can contact the front hook 7, and the other end of the top block 19 can contact the electromagnet 20. One end of the spring 21 is connected to the top block 19 located between the rotating shaft 18 and the electromagnet 20, and the other end of the spring 21 is connected to the connecting shell 2. When there is no external force, the spring 21 is in an extended state, and the other end of the top block 19 is not in contact with the electromagnet 20.

A second contact slope 24 and a second plane 25 are provided at the other end of the front hook 7, and the second contact slope 24 and the second plane 25 are connected, and the first contact slope 22 matches the second contact slope 24. When the front hook 7 is not clamped, the other end of the top block 19 is not in contact with the electromagnet 20. As the front hook 7 is clamped, the contact area between the first contact slope 22 and the second contact slope 24 increases first and then decreases, until the first plane 23 of the top block 19 contacts the second plane 25 of the front hook 7, and the other end of the top block 19 contacts the electromagnet 20, and the electromagnet 20 is energized to achieve locking.

[0054] In this embodiment, a first limiting step 26 is further provided at one end of the top block 19, and the first limiting step 26 is located below the first plane 23. A second limiting step 27 is provided at the other end of the front hook 7, and the second limiting step 27 is located below the second contact slope 24. After the front hook 7 contacts the support plate and the electromagnet 20 is energized, as the walking mechanism 1 moves forward, the second limiting step 27 can contact the first limiting step 26. After the electromagnet 20 is de-energized, as the walking mechanism 1 moves backward, the other end of the front hook 7 can pass between the first plane 23 and the first limiting step 26.

[0055] In this embodiment, the toggle drive structure includes a second drive motor 13, a third bevel gear 14, a fourth bevel gear 15 and a crank 16. The third bevel gear 14 is located at the power output end of the second drive motor 13. The third bevel gear 14 is meshed with the fourth bevel gear 15. The fourth bevel gear 15 is connected to one end of the crank 16 through a toggle shaft 35. The toggle shaft 35 is rotatably connected to the connecting housing 2 through a bearing. The other end of the crank 16 is rotatably connected to the middle of the connecting rod 6 through a pin. The rear end of the connecting rod 6 passes through the sliding seat 17 and is slidably connected to the sliding seat 17. The sliding seat 17 is rotatably connected to the connecting housing 2 through a seat bearing 36. The second drive motor 13 drives the third bevel gear 14 to rotate, and then the fourth bevel gear 15 drives the crank 16 to rotate. The crank 16 drives the connecting rod 6 to slide along the sliding seat 17. At the same time, the sliding seat 17 rotates relative to the connecting housing 2, and the toggle wheel 5 at one end of the connecting rod 6 toggles the rotor.

[0056] This embodiment also includes a sensing sheet 33 and an origin detection switch 34. The sensing sheet 33 is arranged on the connecting rod 6, and the origin detection switch 34 is arranged on the connecting shell 2. After each startup, the toggle drive structure drives the connecting rod 6 and the dial wheel 5 to move. When the origin detection switch 34 detects the sensing sheet 33, the toggle mechanism 3 is located at the origin.

[0057] like Figures 14 to 22As shown, when the rotor toggling device pre-toggles the rotor, the walking mechanism 1 drives the toggling mechanism 3 and the clamping mechanism 4 to move forward, and the front guide block 29 first contacts the support plate and plays a guiding role, so that the support plate bypasses the front hook 7, and the rotor toggling device continues to move forward, and the support plate contacts the rear hook 8. As the toggling device continues to move forward, the rear hook 8 deflects under the action of the support plate, and drives the front hook 7 to move toward the support plate through the connecting rod 39 until the front hook 7 and the rear hook 8 clamp the support plate; in the process of the front hook 7 moving toward the support plate, the second contact surface of the other end of the front hook 7 contacts the first contact inclined surface 22 at one end of the top block 19, and as the contact area of ​​the first contact inclined surface 22 and the second contact inclined surface 24 first increases and then decreases, until the first plane 23 of the top block 19 contacts the second plane 25 of the front hook 7, one end of the top block 19 moves upward, and the other end of the top block 19 moves downward to compress the spring 21 and contact the electromagnet 20. The first limit step 26 contacts the second limit step 27 to limit the position, ensuring that the front hook 7 does not continue to rotate; when the rotor toggle device completes the toggle and needs to be withdrawn, the electromagnet 20 is powered off, and as the rotor toggle device retreats, the other end of the front hook 7 can pass between the first plane 23 and the first limit step 26. In this process, under the action of the spring 21, the other end of the top block 19 moves upward, the other end of the top block 19 is separated from the electromagnet 20, and one end of the top block 19 moves downward, so that the rotor toggle device can be withdrawn normally.

[0058] The walking mechanism 1 of this embodiment can adapt to the arc surface and drive the clamping mechanism 4 and the toggle mechanism 3 to move forward and backward; the toggle mechanism 3 of this embodiment can toggle the rotor to assist in the inspection of the rotor; the clamping mechanism 4 of this embodiment can automatically clamp the support plate to prevent the rotor toggle device from moving backward. After the electromagnet 20 is powered off, the clamping mechanism 4 can automatically release the support plate to facilitate the exit of the rotor toggle device.

[0059] The present specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
