[0037] The connecting piece 3, which moves in opposite directions, is slidably disposed on the mounting piece 1 and is used to connect the rotating part and the mounting piece 1. By moving the connecting piece 3, the rotating part rotates on the mounting piece 1, driving the clamping piece 2 to fit against the cable bracket on the utility pole or power tower, thus fixing the testing equipment.

[0038] like Figure 2 , Figure 4 As shown, symmetrically distributed fixing plates 11 are fixed on the mounting component 1. A lead screw 112 and a guide rod 111 are provided between the fixing plates 11. A first motor 110 is fixed on one side of a fixing plate 11 on the mounting component 1. Connecting parts 3 are installed on the lead screw 112 and the guide rod 111. The output end of the first motor 110 is fastened to the lead screw 112 and is used to drive the lead screw 112 to rotate, thereby causing the two connecting parts 3 to move towards or in opposite directions. A bracket 12 is fixed on the mounting component 1.

[0039] The bracket 12 is provided with symmetrically distributed rotating components, including a driving rod 131 and a driven rod 13.

An L-shaped plate 17 is fixedly mounted on one side of the mounting component 1. The driving structure is a swing rod 18. The swing rods 18 are symmetrically distributed on the L-shaped plate 17. When the swing rods 18 are rotated, they push the detection mechanism 5 to move on the moving plate 4. One end of the swing rod 18 is provided with a second gear 181, and the other end is provided with a straight groove 19. The second gears 181 on adjacent swing rods 18 mesh with each other.

After rotating the plug rod 27, it passes through the through hole 141 and extends into the installation groove 14 to slide and cooperate with the first fixing hole 23 to fix the clamping member 2. A limiting rod 24 is fixedly provided on one side of the clamping member 2.

[0042] The positioning block 25 is fastened with stop blocks 26 on both sides. When the positioning block 25 is in contact with the driven rod 13, the stop blocks 26 are engaged with the two sides of the driven rod 13 to prevent the positioning block 25 from moving. The positioning block 25 is provided with a limiting arc plate 28, and the limiting arc plate 28 is provided with an array of limiting grooves 29. The limiting grooves 29 cooperate with the limiting rod 24. When installing the clamping member 2, the clamping member 2 is rotated to a suitable angle according to the angle of the cable bracket so that when the clamping member 2 is fixed, the upper surface of the mounting member 1 is parallel to the insulator. Then the positioning block 25 is installed, and the clamping member 2 is fastened through the limiting grooves 29. The insertion rod 27 is rotated to lock the clamping member 2.

[0044] like Figure 5 As shown, a slide rail 41 is provided on one side of the movable plate 4. The slide rail 41 cooperates with the guide groove 151.

[0045] A shaft 45 is rotatably provided between one side of the placement rod 44 and the U-shaped frame 43. A torsion spring 46 is fixedly connected to the shaft 45 and the torsion spring 46 is fastened to the U-shaped frame 43. The placement rod 44 is provided with an opening groove 47, and a support part 471 is provided in the opening groove 47. One end of the guide rod 48 is provided with a slot 49, and a rotating part 481 is fixedly provided at one end of the guide rod 48. One end of the shaft 45 passes through the opening groove 47 and is fastened to the rotating part 481. A baffle 40 is fixedly provided at the end of the guide rod 48 away from the placement rod 44.

[0046] Under normal conditions, the detection rod 5 is located on the placement rod 44. The torsion spring 46 pulls the shaft rod 45, so that the guide rod 48 is set perpendicular to the placement rod 44. The guide rod 48 stabilizes the detection rod 5. When the detection rod 5 moves outward from the U-shaped frame 43, the detection rod 5 pushes the guide rod 48 to rotate until the slot 49 fits with the support part 471, restricting the rotation of the guide rod 48. At this time, when the guide rod 48 and the placement rod 44 are horizontally connected, the detection rod 5 is moved to slide onto the guide rod 48. After continuing to move the detection rod 5, the working position of the detection rod 5 is adjusted.

[0047] like Figure 6 As shown, a guide hole 51 is provided on one side of the detection rod 5. The guide hole 51 is slidably connected to the placement rod 44 and the guide rod 48. A through groove 52 is provided on one side of the guide hole 51. When the detection rod 5 moves from the placement rod 44 to the guide rod 48, the through groove 52 is used to allow the shaft 45 on the outside of the placement rod 44 to pass through. A drive rod 53 is fixedly provided at one end of the detection rod 5. The drive rod 53 is slidably connected to the straight groove 19. When the swing rod 18 rotates, the drive rod 53 slides horizontally with the straight groove 19. An arc-shaped seat 54 is fixedly provided on the detection rod 5. An arc-shaped guide rail 55 is provided on the arc-shaped seat 54. The arc-shaped guide rail 55 is slidably connected to the arc-shaped seat 54 through an arc-shaped sliding rod 551.

[0048] An arc-shaped rack 553 is provided on the arc-shaped guide rail 55. A third gear 56 is rotatably provided on the detection rod 5. The third gear 56 cooperates with the arc-shaped rack 553. A fourth motor 560 is fixedly provided on the detection rod 5. The output end of the fourth motor 560 is fastened to the third gear 56. A second fixing hole 552 is provided on one side of the arc-shaped guide rail 55. A detection frame 57 is provided on one side of the arc-shaped guide rail 55. The detection frame 57 is installed on the arc-shaped guide rail 55 by bolts passing through the detection frame 57 and cooperating with the second fixing hole 552.

[0049] The testing frame 57 is equipped with a fourth gear 58, which is rotatably connected to the shaft of the testing frame 57. A vertical rod 59 is fixedly mounted on the fourth gear 58, and impact parts 591 are provided on both sides of the vertical rod 59. The impact parts 591 apply impact force to the insulator to test the impact resistance of the insulator. An electric cylinder 500 is fixedly mounted on one side of the testing frame 57. The output end of the electric cylinder 500 is connected to a second rack 50 for rotating the fourth gear 58. The rack 50 meshes with the fourth gear 58.

[0050] The test frame 57 can also be configured as a vibrator, which can generate excitation for the device under test and replace the test frame 57 to perform strength testing on the insulator.

[0051] When using this device to test a live insulator, move the mounting piece 1 to the top of the cable rack or pole. Adjust the rotating clamping piece 2 to a suitable angle according to the top cable support. To ensure that the upper surface of the mounting piece 1 is parallel to the insulator when the clamping piece 2 is fixed, after adjusting the clamping piece 2, install the positioning block 25 and tighten the clamping piece 2 through the limiting groove 29. Rotate the insertion rod 27 to lock the clamping piece 2. The installed detection rod 5 is located below the insulator. Rotate the swing rod 18, which pushes the detection rod 5 to move, aligning the detection structure on the detection rod 5 with the insulator. Then, the electric cylinder 500 pushes the second rack 50 to move, and the impact part 591 applies an impact to the insulator to test its impact resistance.

[0052] After testing, the existing acoustic wave collection equipment is used to collect the acoustic wave data of the impact. Then, relevant testing personnel analyze the data to obtain a spectrum analysis diagram, which is compared with the spectrum analysis diagram of an existing normal insulator to determine whether there are any defects or other problems inside the insulator. In this way, the strength of the live insulator is tested using a vibrator, and the method is the same.
