Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to an insulating clamp for live-line working tools. Background Technology

[0002] Electrical insulating clamps are tools used in high-voltage power systems, primarily for installing and removing high-voltage fuses and other similar tasks. They are suitable for power systems of 35kV and below, ensuring safe operation during live work. When using insulating clamps, grounding wires are not permitted to prevent grounding short circuits and electric shock accidents. In humid weather, dedicated rainproof insulating clamps should be used. Insulating clamps should be stored in a dedicated box or case to prevent moisture and wear. Furthermore, insulating clamps should undergo a withstand voltage test annually to ensure their electrical performance.

[0003] Currently available live-line working tools, such as insulating clamps, still have the problem of not being able to limit the movement of the two connecting rods. Because the two connecting rods of the insulating clamp are relatively loose, after lifting one connecting rod, the other falls down and separates. Therefore, after clamping with the insulating clamp during live-line work, continuous force is required to ensure the clamping effect, which is quite inconvenient. Utility Model Content

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figures 1 to 4An insulating clamp for live-line working tools includes a first jaw 1 and a second jaw 2. A connecting rod 3 is fixedly mounted at one end of both jaws 1 and 2, and the jaws 1 and 2 are rotatably connected. An insulating handle 4 is fixedly mounted at one end of each connecting rod 3, and a fixing block 5 is fixedly mounted at one end of each insulating handle 4. One fixing block 5 has an arc-shaped groove 6 on one side, and slots 7 are formed at both ends of the arc-shaped groove 6 and inside one fixing block 5. The other fixing block 5 has an arc-shaped locking block 10 on one side, and first sliding grooves 11 are formed at both ends of the arc-shaped locking block 10. Three first sliding grooves 11 are fixedly mounted inside each of the two first sliding grooves 11. A spring 12 is provided, and a first insert 13 is fixedly installed at one end of every three first springs 12. Two first inserts 13 are slidably connected to the inside of two first sliding grooves 11 respectively. One end of the two first inserts 13 is inserted into the inside of two slots 7 respectively. Because the connecting rods 3 of the two components of the insulating clamp are relatively loose, after lifting one connecting rod 3, the other will fall down and separate. Therefore, after clamping with the insulating clamp during live work, it is generally necessary to apply continuous force to ensure the clamping effect. After clamping, pull the arc-shaped locking block 10 to insert the two first inserts 13 into the inside of the two slots 7 respectively for limiting and fixing the two connecting rods 3, effectively restricting their rotation.

[0031] Please see Figures 5 to 6 One of the fixing blocks 5 has a first fixing groove 8 inside, and a connecting rope 9 is provided inside the first fixing groove 8. A rotating column 16 is rotatably installed inside the first fixing groove 8. One end of the connecting rope 9 is fixedly connected to the outer wall of the rotating column 16, and the other end of the connecting rope 9 is fixedly connected to one side of the arc-shaped locking block 10. When the arc-shaped locking block 10 is pulled, the rotating column 16 will rotate and lengthen the connecting rope 9.

[0032] A second fixing groove 14 and a third fixing groove 17 are provided inside one of the fixing blocks 5 and on both sides of the first fixing groove 8. The two ends of the rotating column 16 extend into the interior of the second fixing groove 14 and the third fixing groove 17, respectively. A helical spring 15 is fixedly installed inside the second fixing groove 14. One end of the second fixing groove 14 is fixedly connected to the outer wall of one end of the rotating column 16. When the rotating column 16 rotates, it will cause one end of the helical spring 15 to rotate. After the arc-shaped locking block 10 is fixed, the helical spring 15 returns to its original position and the excess connecting rope 9 is wound into the interior of the first fixing groove 8.

[0033] Please see Figure 8A gear 18 is rotatably installed inside the third fixing groove 17. One end of the rotating column 16 is fixedly connected to the center of the third fixing groove 17. A second sliding groove 19 is provided inside one of the fixing blocks 5 and above the third fixing groove 17. A shaped insert 21 is slidably installed inside the second sliding groove 19. One end of the shaped insert 21 is inserted into the third fixing groove 17. After the arc-shaped card block 10 is fixed, the shaped insert 21 is manually pressed down to move one end of the shaped insert 21 into the third fixing groove 17 and insert it into the groove of the corresponding gear 18 for limiting and preventing the gear 18 from rotating, thus effectively limiting the length of the connecting rope 9.

[0034] Two second springs 20 are fixedly installed inside the second sliding groove 19. One end of each of the two second springs 20 is fixedly connected to one side of the irregular insert 21. When the gear 18 does not need to be limited, the upward thrust of the two second springs 20 can prevent the irregular insert 21 from moving downward.

[0035] Please see Figure 7 One of the fixed blocks 5 has two limiting grooves 22 inside, and the irregular-shaped insert 21 has a third sliding groove 23 inside. A third spring 24 is fixedly installed inside the third sliding groove 23. A limiting block 25 is fixedly installed at one end of the third spring 24. The limiting block 25 is slidably connected to the inside of the third sliding groove 23. One end of the limiting block 25 is inserted into the inside of one of the limiting grooves 22. When the irregular-shaped insert 21 is pressed down, the pushing force of the third spring 24 on the limiting block 25 will insert one end of the limiting block 25 into the corresponding limiting groove 22, thereby limiting the irregular-shaped insert 21.

[0036] Working principle:

[0037] After using insulated clamps to hold the device during live-line work, pull the arc-shaped locking block 10 to insert the two first insert blocks 13 into the two slots 7 respectively for limiting. Then press down on the irregularly shaped insert block 21. Through the pushing force of the third spring 24 on the limiting block 25, one end of the limiting block 25 is inserted into the corresponding limiting groove 22. At this time, one end of the irregularly shaped insert block 21 moves into the third fixing groove 17 and inserts into the groove of the corresponding gear 18 for limiting, preventing the gear 18 from rotating, and effectively limiting the length of the connecting rope 9.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
