Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] This application provides a tool for installing wire clamps, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application.

[0047] See Figure 1 In one application scenario, the wire clamp 100 has a screw part 101 and a clamping part 102. The clamping part 102 is used for clamping by a fixture, and rotating the screw part 101 can be used to clamp and fix the wire clamp 100 to the cable.

[0048] See Figure 2 and Figure 3 In one embodiment, the live wire clamp installation tool includes: a clamping rod 1, the end of which is provided with a clamping mechanism 2 for clamping the wire clamp; the clamping mechanism 2 includes: a base 21; a fixed clamping arm 22, fixedly mounted on the base 21; a movable clamping arm 23, movably mounted on the base 21; and a threaded rod 24, threadedly engaged with the base 21; wherein the lower end of the threaded rod 24 is used to connect with the clamping rod 1, and the upper end is rotatably connected to the movable clamping arm 23; wherein when the threaded rod 24 rotates, the threaded rod 24 drives the movable clamping arm 23 to move toward or away from the fixed clamping arm 22.

[0049] In this embodiment, rotating the clamping rod 1 can drive the threaded rod 24 to rotate. Since the threaded rod 24 is threadedly engaged with the base 21, the two will move relative to each other when the threaded rod 24 rotates, thereby driving the movable clamping arm 23 to move toward or away from the fixed clamping arm 22, which can facilitate clamping or releasing the wire clamp, and make it convenient for manual remote installation of the wire clamp on the cable.

[0050] See Figure 6 Optionally, the base 21 is provided with an assembly groove 211; the fixed clamping arm 22 is L-shaped and includes a first connecting arm 221 and a first clamping arm 222 that are perpendicular to each other; the first connecting arm 221 is fixedly connected to the base 21; the movable clamping arm 23 is L-shaped and includes a second connecting arm 231 and a second clamping arm 232 that are perpendicular to each other; the second connecting arm 231 is inserted into the assembly groove 211 of the base 21 and is rotatably connected to the upper end of the threaded rod 24.

[0051] In this embodiment, the first connecting arm 221 of the fixed clamping arm 22 may be fixed in the assembly groove 211; the second connecting arm 231 of the movable clamping arm 23 may be inserted in the assembly groove 211 and can move up and down in the assembly groove 211; the lower end of the second connecting arm 231 is rotatably connected to the threaded rod 24, and the threaded rod 24 can drive the second connecting arm 231 to move up and down when it rotates.

[0052] See Figure 4 and Figure 6 Optionally, the lower end of the base 21 is provided with a threaded hole 212 communicating with the assembly groove 211; the upper end of the threaded rod 24 extends into the assembly groove 211 through the threaded hole 212 and cooperates with the lower end of the second connecting arm 231.

[0053] To ensure the stability of the movable clamping arm 23 during operation, a guide ring 2211 is fixed on the first connecting arm 221; the second connecting arm 231 is accommodated within the guide ring 2211. The second connecting arm 231 can move up and down within the guide ring 2211, and the guide ring 2211 can limit the radial movement of the second connecting arm 231, thereby improving its operational stability.

[0054] Preferably, the clamping ends of the first clamping arm 222 and the second clamping arm 232 are provided with wedge-shaped portions 2221. The wedge-shaped portions 2221 help them engage with the clamping portions 102 on the wire clamp 100.

[0055] See Figures 4 to 6As an optional mating method between the movable clamping arm 23 and the threaded rod 24, the connecting end of the movable clamping arm 23 and the threaded rod 24 is provided with a slot 233; the upper end of the threaded rod 24 is provided with a connecting part 241 that is accommodated in the slot 233, and the outer periphery of the connecting part 241 is provided with an annular groove 242; at least one through hole 234 is provided on the side wall of the slot 233 for accommodating a fixing member 235; the fixing member 235 is inserted into the annular groove 242 through the through hole 234.

[0056] See Figure 6 In one application scenario, during assembly, the lower end of the movable clamping arm 23 can be inserted into the assembly groove 211 from top to bottom. Then, the upper end of the threaded rod 24 is screwed into the assembly groove 211 through the threaded hole 212 and inserted into the slot 233. Then, the fastener 235 is inserted into the annular groove 242 through the through hole 234, thereby rotatably connecting the threaded rod 24 and the movable clamping arm 23.

[0057] Optional, see Figure 2 The lower end of the threaded rod 24 is connected to the clamping rod 1 via the spline head assembly 5. The spline head assembly 5 is existing technology and will not be described in detail here.

[0058] Optionally, a hook 6 is connected to the base 21. The hook 6 allows personnel to hang tools on the cable for temporary rest when not operating or waiting.

[0059] Further, see Figure 1 The live wire clamp installation tool further includes an operating lever 3, the end of which is provided with an operating head 4 for operating the wire clamp.

[0060] In one application scenario, during installation, the clamp 100 held by the clamping mechanism 2 is placed on the cable by the clamping rod 1, and then the screw part 101 on the clamp 100 is tightened by the operating rod 3.

[0061] For details, see Figure 7 The operating head 4 includes a universal sleeve 41, the operating end of which is provided with a receiving part 411 for accommodating bolts on the wire clamp, and the connecting end of which is connected to the upper end of the operating rod 3.

The universal sleeve 41 has a universal joint in the middle, which can facilitate angle adjustment. Optionally, the connecting end of the universal sleeve 41 can also be connected to the upper end of the operating lever 3 through the spline head assembly 5.

[0063] Furthermore, a flared guide sleeve 412 is provided on the outer periphery of the operating end of the universal sleeve 41. This facilitates the insertion of the head of the screw portion 101 into the receiving portion 411.

[0064] In this embodiment, the clamping rod 1 and the operating rod 3 can be spliced ​​together to change their length and adapt to different application scenarios.

[0065] In summary, this utility model's live wire clamp installation tool allows construction workers to install wire clamps on overhead cables remotely, eliminating the need for high-altitude operations. Workers do not need to directly touch the wire clamps or overhead cables, ensuring good safety, and the overhead cables do not require power outages during installation. Clamping and loosening the wire clamps only requires rotating the clamping rod, making operation convenient. Multiple clamping rods and operating rods can be connected in series to change their length, allowing for flexible configuration according to the usage environment and increasing applicability.
