[0035] The guide column 22, the guide sleeve 23, the compression spring 24, the guide block 26, the guide hole 25 and the fourth connecting plate 52 are designed so that the carrier 5 is elastically connected to the first rotating shaft 9, the compression spring 24 is in a compressed state, the guide block 26 is in contact with the inner wall of the guide hole 25 on one side of the movable frame 21, the compression spring 24 supports the movable frame 21 and the carrier 5, the bottom of the second support column 8 located above is in contact with the top of the bracket 27, when the first damping plate 10 located below the rectangular frame 4 moves from the top of the operating table 1 to the top of the second damping plate 16, the first support column 7 located above slides to the top of the bracket 19, and the second support column 8 located above moves to the top of the third avoidance hole 29, and the top of the porcelain insulator has no position In the upper accommodating groove 6, the second damping disc 16 is in contact with the first damping disc 10, and the second damping disc 16 is driven to rotate by the first motor 14.

When it is necessary to drive the porcelain insulator and the rectangular frame 4 located at the detection station to flip 180 degrees, the fixing frame 17 and the support plate 12 are driven downward by the hydraulic telescopic rod 18, so that the second damping disc 16 is no longer in contact with the first damping disc 10, and the support plate 12 is moved downward, and the support plate 12 and the second damping disc 16 will not interfere with the rectangular frame 4 and the first damping disc 10 flipping 180 degrees, and the support plate 12 drives the support plate 19 to move downward through the first connecting plate 20. The compression spring 24 located at the top pushes the corresponding movable frame 21 and the object carrier 5 to move downward with the support plate 19, and the second support column 8 located at the top passes through the third avoidance hole 29, and finally the top of the porcelain insulator is inserted into the accommodating groove 6 located at the top. The support plate 19 no longer supports the first support column 7 located at the top, and the porcelain insulator is clamped by the two object carriers 5. When the rotary switching mechanism drives the rectangular frame 4 to flip 180 degrees, the first support column 7 originally located at the bottom moves to the top of the support plate 19. At this time, the hydraulic telescopic rod 18 drives the fixed frame 17 and the support plate 12 to move up, so that the second damping disk 16 and the first damping disk 10 are contacted again, and the support plate 12 pushes the object carrier 5 located at the top to move up through the first connecting plate 20 and the support plate 19.

When the inspection of the porcelain insulator located in the rectangular frame 4 is completed, the rotary switching mechanism drives the rectangular frame 4 to move toward the loading and unloading station, and the second support column 8 located above slides on the top of the bracket 27. At this time, the top of the porcelain insulator is not located in the upper receiving groove 6, and the second support column 8 located below moves to the bottom of the support bar 30.As the second support column 8 continues to move, the second support column 8 slides from the inclined surface of the support block 31 to the bottom of the support block 31, and the support block 31 can push the second support column 8, the carrier 5 and the porcelain insulator located below to move downward synchronously, so that when the porcelain insulator moves to the loading and unloading station, the distance between the two carriers 5 is greater than the length of the porcelain insulator, ensuring that the staff can drive the bottom end of the porcelain insulator to be pulled out of the receiving groove 6.

[0037] The worm 39 is driven to rotate by the second motor 38, and the worm 39 drives the support tube 34 and the control box 33 to rotate through the worm gear 37. The control box 33 drives the rectangular frame 4 and the porcelain insulator to revolve around the support tube 34 through the second rotating shaft 35 and the third connecting plate 36, and the bottom of the first damping disk 10 located below slides on the top of the operating table 1, and the second rotating shaft 35 and the fourth damping disk 47 are fixed relative to the control box 33. At this time, the second bevel gear 45 rolls on the first bevel gear 43, and the third damping disk 46 cannot drive the fourth damping disk 47 to rotate synchronously by friction. When the hydraulic telescopic rod 18 drives the support tube 34, the third damping disk 46 can not drive the fourth damping disk 47 to rotate synchronously. The support plate 12 moves downward, the second damping disc 16 is no longer in contact with the first damping disc 10, and the second damping disc 16 and the support plate 12 no longer interfere with the rectangular frame 4 and the porcelain insulator. When the rectangular frame 4 and the porcelain insulator are turned 180 degrees, the third motor 42 drives the third rotating shaft 40 to rotate, and the third rotating shaft 40 drives the second bevel gear 45, the connecting shaft 44 and the third damping disc 46 to rotate through the first bevel gear 43. Since the rectangular frame 4 and the first damping disc 10 located at the detection station are not interfered by the support plate 12 and the second damping disc 16, the corresponding third damping disc 46 drives the fourth damping disc 47 and the second rotating shaft 35 through friction. The second rotating shaft 35 drives the rectangular frame 4 located at the detection station to flip over through the third connecting plate 36, and the other rectangular frames 4 still cannot flip over. When the hydraulic telescopic rod 18 drives the support plate 12 and the second damping plate 16 to move up to the initial height, the second damping plate 16 supports the first damping plate 10 again. When the second motor 38 is started again, the control box 33 can drive all the rectangular frames 4 to revolve around the support tube 34 again through the second rotating shaft 35 and the third connecting plate 36. The first damping plate 10 located below the rectangular frame 4 slides relative to the operating table 1, and the staff drives two adjacent nuts 51 no longer clamps the clamping plate 50, and releases the fixation of the screw rod 48 and the detection camera 3. The staff drives the screw rod 48 and the detection camera 3 to slide horizontally relative to the rectangular hole 49, and the staff drives the screw rod 48 and the detection camera 3 to move vertically to change the position of the detection camera 3. When the position of the detection camera 3 is adjusted, the staff drives the two adjacent nuts 51 to rotate so that the two adjacent nuts 51 clamp the clamping plate 50, so that the two clamping plates 50 clamp the operating table 1, and the clamping plate 50, the screw rod 48 and the detection camera 3 are fixed relative to the operating table 1.

[0038] Working principle: The staff places the porcelain insulator to be inspected in the rectangular frame 4 located at the loading and unloading station, supports the porcelain insulator through a carrier 5 located below, and inserts the bottom end of the porcelain insulator into the receiving groove 6 located below, and drives the rectangular frame 4 with the porcelain insulator to move to the inspection station through the rotary switching mechanism, and drives the first damping disk 10 located below the rectangular frame 4 to rotate through the lifting friction drive structure, and the first damping disk 10 drives the carrier 5 to rotate through the first rotating shaft 9, so that the porcelain insulator located at the inspection station can rotate, and the porcelain insulator is photographed by the inspection camera 3. When the porcelain insulator rotates one circle, the pushing mechanism pushes the porcelain insulator located at the inspection station to rotate. The object carrier 5 above the insulator moves downward so that two adjacent carriers 5 clamp the porcelain insulator, and the rectangular frame 4 and the porcelain insulator are driven to flip 180 degrees by the rotation switching mechanism, and then the object carrier 5 located above the porcelain insulator is pushed upward by the pushing mechanism, so that the bottom end of the original porcelain insulator is rotated to the top, and the bottom end of the original porcelain insulator is exposed, and the first damping disk 10 located below the rectangular frame 4 is driven to rotate again by the lifting friction driving structure, so that the porcelain insulator located at the detection station rotates one circle, and the detection camera 3 can complete the shooting of the entire porcelain insulator, and can shoot the blocked part of the porcelain insulator, without the need for secondary detection, thereby improving the detection efficiency and convenience;

The second damping disc 16 can drive the first damping disc 10 and the first rotating shaft 9 to rotate by friction, and the first rotating shaft 9 can drive the corresponding porcelain insulator to rotate. When it is necessary to drive the porcelain insulator and the rectangular frame 4 located at the detection station to flip 180 degrees, the fixing frame 17 and the support plate 12 are driven downward by the hydraulic telescopic rod 18, so that the second damping disc 16 is no longer in contact with the first damping disc 10, and the support plate 12 is moved downward, and the support plate 12 and the second damping disc 16 will not interfere with the rectangular frame 4 and the first damping disc 10 flipping 180 degrees, and the support plate 12 drives the support plate 19 to move downward through the first connecting plate 20. The compression spring 24 located at the top pushes the corresponding movable frame 21 and the object carrier 5 to move downward with the support plate 19, and the second support column 8 located at the top passes through the third avoidance hole 29, and finally the top of the porcelain insulator is inserted into the accommodating groove 6 located at the top. The support plate 19 no longer supports the first support column 7 located at the top, and the porcelain insulator is clamped by the two object carriers 5. When the rotary switching mechanism drives the rectangular frame 4 to flip 180 degrees, the first support column 7 originally located at the bottom moves to the top of the support plate 19. At this time, the hydraulic telescopic rod 18 drives the fixed frame 17 and the support plate 12 to move up, so that the second damping disk 16 and the first damping disk 10 are contacted again, and the support plate 12 pushes the object carrier 5 located at the top to move up through the first connecting plate 20 and the support plate 19. The preset position can make the bottom end of the original porcelain insulator detach from the corresponding receiving groove 6, so that the bottom end of the original porcelain insulator is exposed, and the first motor 14 drives the second damping disk 16 to rotate again, and the second damping disk 16 can drive the first damping disk 10 and the first rotating shaft 9 to rotate through friction, so that the bottom end of the original porcelain insulator rotates one circle, and the detection camera 3 can shoot the blocked part of the original porcelain insulator. When the inspection of the porcelain insulator located in the rectangular frame 4 is completed, the rotary switching mechanism drives the rectangular frame 4 to move toward the loading and unloading station, and the second support column 8 located above slides on the top of the bracket 27. At this time, the top of the porcelain insulator is not located in the upper receiving groove 6, and the second support column 8 located below moves to the bottom of the support bar 30.As the second support column 8 continues to move, the second support column 8 slides from the inclined surface of the support block 31 to the bottom of the support block 31, and the support block 31 can push the second support column 8, the carrier 5 and the porcelain insulator located below to move downward synchronously, so that when the porcelain insulator moves to the loading and unloading station, the distance between the two carriers 5 is greater than the length of the porcelain insulator, ensuring that the staff can drive the bottom end of the porcelain insulator to be pulled out of the accommodating groove 6;

[0040] The worm 39 is driven to rotate by the second motor 38, and the worm 39 drives the support tube 34 and the control box 33 to rotate through the worm gear 37. The control box 33 drives the rectangular frame 4 and the porcelain insulator to revolve around the support tube 34 through the second rotating shaft 35 and the third connecting plate 36, and the bottom of the first damping disk 10 located below slides on the top of the operating table 1, and the second rotating shaft 35 and the fourth damping disk 47 are fixed relative to the control box 33. At this time, the second bevel gear 45 rolls on the first bevel gear 43, and the third damping disk 46 cannot drive the fourth damping disk 47 to rotate synchronously by friction. When the hydraulic telescopic rod 18 drives the support tube 34, the third damping disk 46 can not drive the fourth damping disk 47 to rotate synchronously. The support plate 12 moves downward, the second damping disc 16 is no longer in contact with the first damping disc 10, and the second damping disc 16 and the support plate 12 no longer interfere with the rectangular frame 4 and the porcelain insulator. When the rectangular frame 4 and the porcelain insulator are turned 180 degrees, the third motor 42 drives the third rotating shaft 40 to rotate, and the third rotating shaft 40 drives the second bevel gear 45, the connecting shaft 44 and the third damping disc 46 to rotate through the first bevel gear 43. Since the rectangular frame 4 and the first damping disc 10 located at the detection station are not interfered by the support plate 12 and the second damping disc 16, the corresponding third damping disc 46 drives the fourth damping disc 47 and the second rotating shaft 35 through friction. The second rotating shaft 35 drives the rectangular frame 4 located at the detection station to flip over through the third connecting plate 36, and the other rectangular frames 4 still cannot flip over. When the hydraulic telescopic rod 18 drives the support plate 12 and the second damping plate 16 to move up to the initial height, the second damping plate 16 supports the first damping plate 10 again. When the second motor 38 is started again, the control box 33 can drive all the rectangular frames 4 to revolve around the support tube 34 again through the second rotating shaft 35 and the third connecting plate 36. The first damping plate 10 located below the rectangular frame 4 slides relative to the operating table 1, and the staff drives two adjacent nuts 51 no longer clamps the clamping plate 50, and releases the fixation of the screw rod 48 and the detection camera 3. The staff drives the screw rod 48 and the detection camera 3 to slide horizontally relative to the rectangular hole 49, and the staff drives the screw rod 48 and the detection camera 3 to move vertically to change the position of the detection camera 3. When the position of the detection camera 3 is adjusted, the staff drives the two adjacent nuts 51 to rotate so that the two adjacent nuts 51 clamp the clamping plate 50, so that the two clamping plates 50 clamp the operating table 1, and the clamping plate 50, the screw rod 48 and the detection camera 3 are fixed relative to the operating table 1.
