Technical Field
[0001] This invention relates to the field of high-voltage electrical equipment maintenance technology, and specifically to an insulating clamping tool for high-voltage electrical equipment maintenance. Background Technology
[0002] Insulating clamping tools for high-voltage electrical equipment maintenance (commonly known as insulating clamps) are special insulating safety tools for power systems of 35kV and below. They are primarily used for live / near-electric work such as removing and installing high-voltage fuses, operating disconnect switches / drop-out fuses, and removing and installing temporary grounding wires, ensuring the insulation isolation of personnel from high-voltage live parts.
[0003] Existing insulating clamping tools for high-voltage electrical equipment maintenance typically employ purely manual clamps, requiring sustained gripping force after clamping. This can lead to arm pain and unstable force exertion after prolonged operation, potentially resulting in slippage. Therefore, it is necessary to provide an insulating clamping tool for high-voltage electrical equipment maintenance to address these technical issues. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] In order to overcome the shortcomings of existing technology, an insulated clamping tool for the maintenance of high-voltage electrical equipment is proposed to solve the problems of manual clamps, which require continuous gripping force after clamping, and the resulting arm pain and unstable force after long-term operation.
[0006] (II) Technical Solution
[0007] This invention is achieved through the following technical solution: This invention proposes an insulating clamping tool for the maintenance of high-voltage electrical equipment, comprising a pliers head. A first insulating rod and a second insulating rod are fixedly installed at both ends of the pliers head. A support base is fixedly installed on the outer wall of the first insulating rod. An arc-shaped plate is fixedly installed on the top of the support base. Multiple evenly distributed slots are formed on the outer wall of the arc-shaped plate. A fixing base is fixedly installed on the outer wall of the second insulating rod. One end of the arc-shaped plate is slidably inserted into the fixing base. A sliding groove is formed on the inner wall of the fixing base. A spring is fixedly installed on the inner wall of the sliding groove. A sliding plate is fixedly installed at one end of the spring. A clamping plate is fixedly installed at the bottom of the sliding plate. A connecting rod is fixedly installed on the outer wall of the sliding plate. One end of the connecting rod passes through the sliding groove and is fixedly installed with a pull plate.
[0008] Furthermore, both the first insulating rod and the second insulating rod have a storage groove at one end, and the inner wall of the storage groove has multiple evenly distributed fixing grooves.
[0009] Furthermore, an extension plate is slidably installed inside the storage slot, and a placement plate is fixedly installed on the outer wall of the extension plate. A limiting groove is formed between the placement plate and the extension plate. A threaded rod is rotatably installed on the inner wall of the limiting groove. The top of the threaded rod passes through the placement plate and is fixedly installed with a handle. A limiting plate is threadedly connected to the outer wall of the threaded rod. A fixing block is fixedly installed on the top of the limiting plate, and the top of the fixing block passes through the extension plate.
[0010] Furthermore, handles are fixedly installed on the outer walls of both placement plates.
[0011] Furthermore, buffer pads are fixedly installed on both sides inside the pliers head.
[0012] Furthermore, the outer wall of the card plate is in contact with the inner wall of the card slot.
[0013] (III) Beneficial Effects
[0014] 1. Compared with the prior art, the present invention has the following beneficial effects: The present invention allows the operator to pull the pull plate, which drives the slide plate to move through the connecting rod. The clamping plate leaves the slot, the spring is compressed, and then the operator turns the two handles. The pliers head clamps the component, and the arc plate moves inside the fixed seat. Finally, the operator releases the pull plate, and the spring force pushes the clamping plate into the slot. At this time, the pliers head can be fixed, and the operator no longer needs to apply gripping force, which is convenient to use.
[0015] 2. Compared with the prior art, the present invention has the following beneficial effects: The present invention allows the operator to rotate the handle, which drives the threaded rod to rotate, causing the limiting plate to descend and the fixing block to leave the fixing groove. At this time, the operator pulls the placement plate, the extension plate moves, and the distance between the handle and the pliers head is adjusted. Finally, the operator rotates the handle in the opposite direction, and the fixing block enters the fixing groove, which improves the range of use and makes it easier to adapt to different usage environments.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] An insulating clamping tool for the maintenance of high-voltage electrical equipment includes a pliers head 1. A first insulating rod 3 and a second insulating rod 4 are fixedly installed at both ends of the pliers head 1. A support base 6 is fixedly installed on the outer wall of the first insulating rod 3. An arc-shaped plate 7 is fixedly installed on the top of the support base 6. Multiple evenly distributed slots 10 are formed on the outer wall of the arc-shaped plate 7. A fixing base 8 is fixedly installed on the outer wall of the second insulating rod 4. One end of the arc-shaped plate 7 is slidably inserted into the fixing base 8. A sliding groove 11 is formed on the inner wall of the fixing base 8. A spring 12 is fixedly installed on the inner wall of the sliding groove 11. A sliding plate 13 is fixedly installed on one end of the spring 12. A clamping plate 14 is fixedly installed on the bottom of the sliding plate 13. A connecting rod 15 is fixedly installed on the outer wall of the sliding plate 13. One end of the connecting rod 15 passes through the sliding groove 11 and is fixedly installed with a pull plate 9.
[0023] In this embodiment, the operator pulls the pull plate 9, which drives the slide plate 13 to move via the connecting rod 15. The clamping plate 14 leaves the slot 10, and the spring 12 is compressed. Then, the operator rotates the two handles 5, and the pliers head 1 clamps the component. The arc plate 7 moves inside the fixing seat 8. Finally, the operator releases the pull plate 9, and the elastic force of the spring 12 pushes the clamping plate 14 into the slot 10. At this time, the pliers head 1 can be fixed, and the operator can stop applying gripping force, making it convenient to use.
[0024] Furthermore, a storage groove 16 is provided at one end of both the first insulating rod 3 and the second insulating rod 4, and a plurality of evenly distributed fixing grooves 17 are provided on the inner wall of the storage groove 16.
[0025] Furthermore, an extension plate 18 is slidably installed inside the storage slot 16, and a placement plate 19 is fixedly installed on the outer wall of the extension plate 18. A limiting groove 20 is opened between the placement plate 19 and the extension plate 18. A threaded rod 21 is rotatably installed on the inner wall of the limiting groove 20. The top of the threaded rod 21 passes through the placement plate 19 and is fixedly installed with a handle 22. A limiting plate 23 is threadedly connected to the outer wall of the threaded rod 21. A fixing block 24 is fixedly installed on the top of the limiting plate 23. The top of the fixing block 24 passes through the extension plate 18.
[0026] Furthermore, handles 5 are fixedly installed on the outer walls of both placement plates 19.
[0027] Furthermore, buffer pads 2 are fixedly installed on both sides inside the pliers head 1 to prevent damage to components.
[0028] Furthermore, the outer wall of the card plate 14 fits against the inner wall of the card slot 10. When the card plate 14 enters the card slot 10, it can be fixed to prevent shaking.
[0029] In this embodiment, the operator rotates the handle 22, which drives the threaded rod 21 to rotate, the limiting plate 23 descends, and the fixing block 24 leaves the fixing groove 17. At this time, the operator pulls the placement plate 19, the extension plate 18 moves, and the distance between the handle 5 and the pliers head 1 is adjusted. Finally, the operator rotates the handle 22 in the opposite direction, and the fixing block 24 enters the fixing groove 17, which improves the range of use and makes it easier to adapt to different usage environments.
[0030] Working principle: In use, the operator rotates the handle 22, which drives the threaded rod 21 to rotate, causing the limiting plate 23 to descend and the fixing block 24 to leave the fixing groove 17. At this time, the operator pulls the placement plate 19, which moves the extension plate 18, adjusting the distance between the handle 5 and the pliers head 1. Finally, the operator rotates the handle 22 in the opposite direction, and the fixing block 24 enters the fixing groove 17, increasing the range of use and making it easier to adapt to different usage environments. When clamping, the operator pulls the pull plate 9, which drives the slide plate 13 to move through the connecting rod 15. The clamping plate 14 leaves the clamping groove 10, and the spring 12 is compressed. Then, the operator rotates both handles 5, and the pliers head 1 clamps the component. The arc plate 7 moves inside the fixing seat 8. Finally, the operator releases the pull plate 9, and the elastic force of the spring 12 pushes the clamping plate 14 into the clamping groove 10. At this time, the pliers head 1 is fixed, and the operator no longer needs to apply gripping force, making it convenient to use.
