[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjustable arc repairing machine for tensioning insulators has the following advantages:

[0017] 1. When in use, the rotary drum is inserted into the circular hole in the middle of the tension insulator blank, and the electric push rod 1 is started by the single-chip microcomputer to drive the three fixed plates to move with the same amplitude in the direction away from the rotary drum until the fixed plate contacts the inner arc surface of the tension insulator blank, and the tension insulator blanks of different apertures are fixed.

The filtered airflow enters the hollow baffle through the air outlet at the upper end of the dust collecting box, and is finally discharged from the air hole to between the two hollow baffles, guiding the flow trajectory of the air, reducing the dispersion of dust to the outside, and making the dust generated during the arc repair process more comprehensively collected.

The adjustable mounting mechanism 6 also includes an electric push rod 2 66 and a conical pressure head 67. The electric push rod 2 66 is arranged at the upper end of the bracket 2.

The adjustable mounting mechanism 6 also includes an adjusting column 65, and the adjusting column 65 includes a hollow column 651, a slide groove 652 and an adjusting cylinder 653. The hollow column 651 is arranged in the middle of the bottom plate 1, and the hollow column 651 is located in the yielding groove in the middle of the rotating drum 61. The outer arc surface of the hollow column 651 is provided with a slide groove 652, and the upper and lower ends of the slide groove 652 are vertically slidably connected with an adjusting cylinder 653. The adjusting cylinder 653 is rotatably connected with the adjacent adjusting plate 64 respectively, and the upper and lower positions of the adjusting plate 64 are adjusted by sliding the adjusting cylinder 653 in the slide groove 652.

The rotation of the insulator embryo body provides space, and the adjustment column 65 also includes an electric push rod 654, a sliding column 655 and a spring 656. The electric push rod 654 is respectively arranged at the upper and lower ends of the hollow column 651, and the telescopic end of the electric push rod 654 is provided with a sliding column 655. The sliding column 655 is respectively slidably connected with the circular hole in the middle of the adjustment tube 653.

When the fixing plate 62 cannot move further, the continued movement of the sliding column 655 will cause the spring 656 to contract.

The bottom plate 1 is provided with a motor 3. The end of the output shaft of the motor 3 and the outer arc surface of the drum 61 are both provided with gears 4. The two gears 4 are meshed and connected. The input end of the motor 3 is electrically connected to the output end of the single-chip microcomputer 7. The motor 3 is started, and the output shaft of the motor 3 rotates. Through the meshing connection of the two gears 4, the motor 3 drives the drum 61 to rotate.

[0030] The working principle of the adjustable arc repairing machine for tension insulators provided by the present invention is as follows: when in use, the tension insulator blank is placed on the upper surface of the bottom plate 1, and the rotating cylinder 61 is inserted into the circular hole in the middle of the tension insulator blank. The electric push rod 654 is started by the single chip computer 7. The tension applied by the telescopic end of the electric push rod 654 to the sliding column 655 is A, the friction force between the adjusting cylinder 653 and the sliding column 655 is B, and the elastic force of the spring 656 is C.The external force on the rotating plate 63 is converted into a vertical force D. Initially, the telescopic end of the electric push rod 654 drives the sliding column 655 to move, pulling the upper spring 656 to contract upward and the lower spring 656 to contract downward. D is less than A+B+C. Under the elastic connection of the spring 656, the sliding column 655 and the adjusting cylinder 653 temporarily move as a whole, driving the adjusting cylinder 653 and the adjusting plate 64 to move up and down, increasing the distance between the two adjusting plates 64. Under the rotation connection of the rotating plate 63, a force is applied to the fixed plate 62 at the same time, pushing the three fixed plates 62 to move in the same amplitude in the direction away from the rotating cylinder 61, until the fixed plate 62 contacts the inner arc surface of the tension insulator blank, and the tension insulator blanks with different apertures are fixed. The three fixed plates 62 move synchronously with the same amplitude, and the position of the tension insulator embryo can be determined. As the fixed plates 62 contact and continue to support the insulator embryo, D becomes larger. When D is greater than A+B+C, the continued movement of the slide column 655 will cause the spring 656 to contract. Under the elastic force of the spring 656, the fixed plate 62 applies a force to the tension insulator embryo, increasing the friction between the fixed plate 62 and the tension insulator embryo. The contraction amplitude of the spring 656 is detected by the distance sensor 657, and the friction between the fixed plate 62 and the tension insulator embryo is determined. The force applied to the tension insulator embryo is adjusted, and then the electric push rod 2 66 is started. The telescopic end of the electric push rod 2 66 drives the conical pressure head 67 to move downward. The conical pressure head 67 is inserted into the interior of the tensioning insulator blank until it contacts the upper end of the tensioning insulator blank. At this time, the lower end of the tensioning insulator blank contacts the supporting ring at the lower end of the rotating drum 61, and the upper and lower positions of the tensioning insulator blank are fixed to complete the fixation of the tensioning insulator blank. The motor 3 is started, and the output shaft of the motor 3 rotates. Through the meshing connection of the two gears 4, the motor 3 drives the rotating drum 61 to rotate, and the adjusting cylinder 653 and the adjusting plate 64 rotate relative to each other. The conical pressure head 67 and the telescopic end of the electric push rod 2 66 rotate relative to each other, driving the tensioning insulator blank fixed on the surface of the rotating drum 61 to rotate at a high speed, and the linear motor 8 is started. The movable seat of the linear motor 8 drives the electric push rod 3 9 and the arc repair head 5 to move up and down, and the electric Push rod 3 9, the telescopic end of the electric push rod 3 9 drives the arc repair head 5 to move left and right, so that the arc repair head 5 contacts the surface of the high-speed rotating tension insulator embryo, and trims the arc surface of the tension insulator embryo to make the arc surface of the tension insulator embryo smoother. During the arc repair process, the electric fan 12 is started to guide the air to flow, so that the airflow between the two hollow baffles 13 carries the dust generated by the arc repair into the dust collecting box 10, and is filtered by the filter 11 and remains in the dust collecting box 10. The filtered airflow enters the hollow baffle 13 through the air outlet at the upper end of the dust collecting box 10, and is finally discharged from the blowing hole 14 to between the two hollow baffles 13, guiding the flow trajectory of the air, reducing the dust from drifting to the outside, and making the collection of arc repair dust more comprehensive. ,
