[0002] Power insulators are devices installed between conductors of different potentials or between conductors and grounded components that can withstand voltage and mechanical stress. They are special insulating controls that can play an important role in overhead transmission lines. Power insulators bear the vertical load of the conductor and the horizontal tension during operation; they are also subject to corrosion from the sun, rain, climate change and chemicals. Power insulators that have reached their service life need to be recycled and reused. The current method for recycling and reusing power insulators is to directly crush them. Power insulators are generally composed of a porcelain body and metal accessories. Traditional crushers are used to process waste insulators. Because power insulators contain metal accessories and have a high hardness, when the power insulators are crushed as a whole, it is easy to accumulate and clog, which can easily cause equipment damage. Summary of the invention

[0005] A conveyor belt is arranged below the discharge port.

[0006] A lifting mechanism is arranged between the hanging plate and the frame, and the lifting mechanism includes a lifting screw and a positioning slide bar. A pulley is arranged on the upper side of the hanging plate through a bearing, and the pulley is threadedly sleeved on the outside of the lifting screw. A sleeve is fixedly arranged on the upper side of the hanging plate, and the sleeve is slidably sleeved on the outside of the positioning slide bar. A transmission belt is arranged between the two pulleys, a driven gear is fixedly arranged on the upper side of the front pulley, and a lifting motor is fixedly arranged on the upper side of the hanging plate, and a driving gear is arranged at the output end of the lifting motor, and the driving gear and the driven gear are meshed with each other.

[0007] The number of the lifting screw rods and the positioning slide rods are both two, and the lifting screw rods and the positioning slide rods are symmetrically arranged.

[0008] The upper ends of the lifting screw rod and the positioning slide rod are both provided with limiting heads.

[0009] An inner groove is arranged in the middle of the hanging plate, a clamping plate is arranged on the upper side of the clamping mechanism, and a buffer spring is arranged between the clamping plate and the inner groove.

[0010] The clamping mechanism includes a shell and a clamping hydraulic cylinder, a fixed clamp seat and a movable clamp seat are arranged inside the shell, a movable block is clamped on the upper side of the movable clamp seat, clamping heads are arranged on the inner sides of the fixed clamp seat and the movable block, a groove is arranged on the upper surface of the movable block, a driving head is arranged at the output end of the clamping hydraulic cylinder, a driving rod is arranged on the outer side of the driving head, and the driving rod and the groove are clamped with each other.

[0011] A slide groove is arranged on the upper side of the movable clamp seat, and a slider is arranged on the lower side of the movable block. The slider and the slide groove are both in a "trapezoidal" shape.

[0012] The clamp is connected with the fixed clamp seat and the moving block through bolts. The clamp is arc-shaped and the inner surface of the clamp is provided with anti-slip grooves.

[0013] A method for using a power insulator breaking device comprises the following steps: Step 1: Before use, prepare the power insulator to be broken and ensure that all parts are properly installed and tightened, especially the lifting mechanism, clamping mechanism and crusher, etc., to ensure that the device can work normally; Step 2: Start the lifting motor to drive the hanging plate to move up and down along the lifting screw and the positioning slide rod, adjust the height of the hanging plate as needed, place the power insulator between the clamping mechanisms, and clamp the power insulator through the clamping mechanisms to keep the power insulator in a vertical state; Step 3: Start the crushing motor, drive the movable jaw plate to open and close periodically through the eccentric shaft, and cooperate with the fixed jaw plate to crush the power insulator into the required particle size. During this period, the lifting mechanism drives the hanging plate to move downward continuously to gradually crush the power insulator; Step 4: Open the discharge port on the lower side of the crusher. The crushed insulator fragments will fall into the conveyor belt below and transport the insulator fragments to the designated collection area or for subsequent processing.

The cooperation between the moving block and the moving clamp seat through the slide groove and the slider makes the clamping process more flexible and stable. The setting of the conveyor belt can conveniently transport the crushed insulator fragments to the designated position, thereby improving work efficiency and convenience of operation.
