[0016] Compared with the prior art, the present invention provides a high-voltage insulator production line turning device, which has the following beneficial effects:

[0017] 1. A high-voltage insulator production line turning device, by arranging a torsion spring, a first plunger, a second plunger, a roller, a hook groove, a pull rod and a hanging rod, the two sliders connected by the electric slide rail drive the synchronous mechanism to move synchronously toward the roller direction, the insulator is intercepted after reaching the roller, because the two sliders still keep moving, the insulator deflects together with the second plunger, and as the slider passes under the roller, the top of the insulator falls toward the direction of the first plunger, at this time, the torsion spring connected to the second plunger is tightened, and the intercepted side of the insulator is subjected to friction resistance, resulting in the forward speed of the insulator being lower than the moving speed of the slider, the insulator gradually detaches from the second plunger and is sleeved on the first plunger after deceleration, and when the second plunger completely passes through the roller, the insulator completely detaches from the second plunger and is sleeved on the first plunger, the second plunger The connected torsion spring recovers its deformation, driving the second plug rod to return to the vertical state. In the process of the insulator being inserted into the first plug rod, its bottom hits the pull rod, causing the hanging rod to disengage from the hook groove, and the first plug rod loses the pulling force from the pull rod. At this time, the insulator and the first plug rod are still under the roller. The electric slide rail controls the slider to move back to the initial position in the opposite direction. The insulator and the first plug rod leave under the roller, and the torsion spring connected to the first plug rod changes from a contracted state to a relaxed state, driving the first plug rod and the insulator to deflect to a vertical state. The second plug rod again undergoes the process of first deflection and then recovery and returns to the initial position, thereby completing the up and down flipping of the insulator. The control process is simple. The electric slide rail only needs to drive the slider to make a reciprocating motion to realize the fully automatic up and down flipping of the insulator with the cooperation of the mechanical structure.

[0018] 2. This kind of high-voltage porcelain production line turning device is provided with connecting rods, threaded columns, fastening nuts and connecting plates. The fastening nuts on the four threaded columns are rotated to make the sides of the fastening nuts close to the adjacent sliders. At this time, the two sides of the sliders are respectively limited by the fastening nuts and the connecting plates, thereby completing the connection between the connecting rod and the two sliders. The four fastening nuts can be unscrewed from the four threaded columns respectively to separate the two sliders. The operation process is simple and convenient for assembly and maintenance of the device.

[0019] 3. A turning device for a high-voltage insulator production line is provided with a push rod motor, a rotating column, a through slot and a slot. The push rod motor pushes the rotating column upward, and the rotating column produces adaptive displacement and rotation inside the through slot. The swing arm deflects accordingly, thereby changing the height of the roller, so that the device is suitable for insulators of different thicknesses. The push rod seat provides support for the push rod motor from the bottom, and the slot is used to accommodate the adaptive deflection of the top of the push rod motor.

[0020] 4. A high-voltage insulator production line turning device is provided with an intercepting rod, a pulley and a sliding frame. In the process of the slider moving toward the roller, when the second plug rod and the insulator come under the roller, the intercepting rod contacts one end of the insulator to prevent the insulator from continuing to move forward, and the second plug rod in the deflected state can smoothly pass under the intercepting rod, thereby ensuring that the insulator quickly and smoothly detaches from the second plug rod and transfers to the first plug rod, and preventing the insulator from being unable to transfer when the friction resistance is too small. The sliding frame and the pulley provide support for the rotating frame from the bottom, thereby fixing the intercepting rod at a preset position. When the intercepting rod needs to be adjusted, the two sliding frames are synchronously slid along the slide groove. After sliding is completed, the screw rod is rotated by the knob so that one end of the screw rod passes through the threaded hole and presses the inner wall of the slide groove to complete the positioning of the sliding frame, and the two rotating frames are adjusted to be stuck in the wheel groove again, thereby changing the fixed position of the intercepting rod, so that the intercepting rod can be adjusted in height within a certain range.

[0039] In the present invention, both sides of the electric slide rail 1 are fixedly connected with side wing frames 13, and the sides away from each other of the two side wing frames 13 are fixedly connected with mounting rods 14, and two fixed arms 15 are respectively fixed at the middle position of the tops of the two mounting rods 14, and the bottom support is provided by the side wing frames 13 and the mounting rods 14 and the fixed arms 15.

[0040] In the present invention, ears 35 are fixedly connected to the middle positions of the tops of the two swing arms 16, and the tops of the two ears 35 are rotatably connected to the rotating frames 21. The same intercepting rod 22 is fixedly connected between the two rotating frames 21. The height of the lowest point of the intercepting rod 22 is higher than the height of the highest point of the first plug rod 7. In the process of the slider 2 moving toward the roller 17, when the second plug rod 20 and the insulator come under the roller 17, the intercepting rod 22 contacts one end of the insulator to prevent the insulator from moving forward, and the second plug rod 20 in the deflected state can pass smoothly under the intercepting rod 22, ensuring that the insulator quickly and smoothly detaches from the second plug rod 20 and is transferred to the first plug rod 7, preventing the insulator from being unable to transfer when the friction resistance is too small.

[0041] In the present invention, the ends of the two mounting rods 14 close to the intercepting rod 22 are provided with a slide groove 23, the tops of the two mounting rods 14 are slidably connected to the sliding frames 24 through the slide groove 23, the tops of the two sliding frames 24 are rotatably connected to the pulleys 25, the side circumferences of the two pulleys 25 are provided with wheel grooves 39, the ends of the two rotating frames 21 close to the intercepting rod 22 are respectively clamped in the inside of the two wheel grooves 39, the bottoms of the two sliding frames 24 are provided with threaded holes 38, the insides of the two threaded holes 38 are threadedly connected with screw rods 37, and the ends of the two screw rods 37 away from the adjacent threaded holes 38 are provided with screw rods 37.

When the intercepting rod 22 needs to be adjusted, the two sliding frames 24 are synchronously slid along the slide groove 23. After sliding, the screw 37 is rotated by the knob 36 so that one end of the screw 37 passes through the threaded hole 38 and presses the inner wall of the slide groove 23 to complete the positioning of the sliding frame 24, and the two rotating frames 21 are adjusted to be stuck in the wheel groove 39 again, thereby changing the fixed position of the intercepting rod 22, so that the intercepting rod 22 can be adjusted in height within a certain range.

[0042] When in use, the insulator is sleeved on the longitudinal second plug rod 20. When it needs to be flipped, the electric slide rail 1 drives the two sliders 2 connected to the synchronization mechanism to move synchronously in the direction of the roller 17. The insulator is intercepted after reaching the roller 17. Since the two sliders 2 still keep moving, the insulator deflects together with the second plug rod 20. As the slider 2 passes under the roller 17, the top of the insulator falls in the direction of the first plug rod 7. At this time, the torsion spring 9 connected to the second plug rod 20 is tightened, and the intercepted side of the insulator is subjected to friction resistance, resulting in the forward speed of the insulator being lower than the moving speed of the slider 2. The decelerated insulator gradually detaches from the second plug rod 20 and is sleeved on the first plug rod 7. When the second plug rod 20 completely passes through the roller 17, the insulator completely detaches from the second plug rod 20 and After the first plug rod 7 is inserted, the torsion spring 9 connected to the second plug rod 20 recovers its deformation, driving the second plug rod 20 to return to the vertical state. During the process of the insulator being inserted into the first plug rod 7, its bottom hits the pull rod 11, causing the hanging rod 34 to disengage from the hook groove 33, and the first plug rod 7 loses the pulling force from the pull rod 11. At this time, the insulator and the first plug rod 7 are still below the roller 17. The slider 2 is controlled by the electric slide rail 1 to move back to the initial position in the opposite direction. The insulator and the first plug rod 7 leave the bottom of the roller 17, and the torsion spring 9 connected to the first plug rod 7 changes from a contracted state to a relaxed state, driving the first plug rod 7 and the insulator to deflect to a vertical state. The second plug rod 20 once again undergoes the process of first deflection and then recovery and returns to the initial position, thereby completing the up and down flipping of the insulator.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
