[0028] Working principle: When in use, the insulator can be placed in the inner cavity of the test frame 3 for testing. The operation of the servo motor 56 will drive the threaded rod 53 on the left to rotate, and then the threaded rods 53 on both sides will be driven to rotate synchronously under the transmission of the synchronous belt 57. When the threaded rods 53 rotate synchronously, the adjacent threaded sleeves 52 will be driven to move backward. When the threaded sleeves 52 move backward, they will drive the translation plate 4 to move backward through the fixed rod 51. When the translation plate 4 moves backward, it will drive the hydraulic push rod 7, the push plate 8, the vertical rod 9 and the pressure plate 10 to move backward. When the pressure plate 10 moves backward to a suitable position, the servo motor can be driven to rotate synchronously. The machine 56 stops running. In addition, when the threaded sleeve 52 moves backward, it will drive the movable rack plate 62 to move backward through the connecting rod 61. When the movable rack plate 62 moves backward, it will drive the adjacent movable gear 63 to rotate. When the movable gear 63 rotates, it will drive the adjacent transmission rod 64 to rotate. When the transmission rod 64 rotates, it will jointly drive the worm 65 to rotate. When the worm 65 rotates, it will drive the worm wheel 66 to rotate. When the worm wheel 66 rotates, it will drive the movable rod to rotate. When the movable rod rotates, it will drive the reciprocating screw 67 to rotate. When the reciprocating screw 67 rotates, it will drive the screw nut 68 to move upward. When the screw nut 68 moves upward, it will pass through L The shaped moving rod 69 drives the push plate 30 to move upward to the outside of the test frame 3, and when the threaded sleeve 52 stops moving, the push plate 30 will also stop moving. The staff can now place the insulator on the push plate 30, and before placing it, the positioning plates 301 on both sides can be pulled to squeeze the adjacent reset springs 305. When the insulator is placed, the pulled positioning plate 301 can be released to restore it under the action of the rebound force of the adjacent reset springs 305, thereby achieving the clamping and positioning of the insulator. After the clamping and positioning is completed, the reverse operation can be performed to make the pressure plate 10 move forward and restore. At this time, the push plate 30 will also drive The insulator moves downward to recover, and after recovery, the hydraulic push rod 7 can be operated. When the hydraulic push rod 7 is in operation, it will drive the pressure plate 10 to move downward into the inner cavity of the test frame 3 to achieve sealing operation, and then the high-pressure water pump 20 is operated. When the high-pressure water pump 20 is in operation, water will enter the test frame 3 along the connecting pipe and the connecting pipe until the pressure in the test frame 3 reaches a suitable level, and then the high-pressure water pump 20 can be stopped. After maintaining for a period of time, the hydraulic push rod 7 can drive the pressure plate 10 to move upward to recover, and then open the valve to discharge the water, and then observe whether the insulator is broken to know the compressive performance of the insulator.
