[0043] First, the wire clamp applicable to the live installation tool provided by the present invention is as follows Figure 2 and 8As shown, the wire clamp 100 includes a metal threaded rod 20 that drives the movable wire clamp 30 to move up and down. The bottom of the metal threaded rod 20 is provided with a plug-in portion 21, and the two sides of the outside of the wire clamp 100 are also provided with clamping portions 53. The wire clamp 100 also includes: a fixed wire clamp 10, one side of which is provided with an opening to form an inner cavity 12 for accommodating the main conductor A, the side wall of the fixed wire clamp 10 is provided with a third guide groove 13 and a through hole penetrating the top surface and the bottom surface of the fixed wire clamp 10; the metal threaded rod 20 passes through the through hole from bottom to top; a movable wire clamp 30 is arranged in the inner cavity 12, one end of which is inserted into the third guide groove 13 and is threadedly connected with the metal threaded rod 20, and when the metal threaded rod 20 rotates, it drives the movable wire clamp 30 to move upward along the metal threaded rod 20 to clamp and tighten the main conductor A; a quick plug connector 40, which is connected to the fixed wire clamp 10, and the drainage wire B contacts the fixed wire clamp 10 after passing through the quick plug connector 40; an insulating layer 50, including an insulating encapsulation and two insulating edge blocks, the insulating encapsulation is coated on the outer surface of the fixed wire clamp 10 to achieve insulation, and the two insulating edge blocks are installed on both sides of the movable wire clamp 30. The clamping parts 53 are arranged on both sides of the outside of the insulating enclosure.

[0044] like Figures 1 to 7 As shown, an embodiment of the present invention provides a live installation tool suitable for the above-mentioned wire clamp 100, the live installation tool comprising: a handheld torque meter 200; an insulating operating rod 300, which is connected to the handheld torque meter 200, and is hollow inside and provided with a transmission shaft, the input end of the transmission shaft is connected to the output end of the handheld torque meter 200, and the output end of the transmission shaft is connected to a rotating head 310; a clamp 400, which is connected to the end of the insulating operating rod 300 and is used to clamp the wire clamp 100. When the wire clamp 100 is placed on the clamp 400, the rotating head 310 is inserted into the plug-in portion 21 at the bottom of the metal threaded rod 20 of the wire clamp 100, the handheld torque meter 200 is turned on, and the torque is transmitted to the metal threaded rod 20 through the transmission shaft and the rotating head 310, so that the metal threaded rod 20 rotates, driving the movable wire clamp 30 to move upward, thereby tightly clamping the main conductor A between the movable wire clamp 30 and the fixed wire clamp 10. The handheld torque meter 200 may be provided with a digital display instrument for displaying the torque value, so as to facilitate the operator to judge whether the torque value reaches a set value. The set value is a torque value that can tighten the main conductor A and is obtained in advance through experiments.

[0045] Specifically, the clamp 400 includes: a slide seat 410, a lower plate 420, an inclined plate 430, two guide blocks 440, two L-shaped top blocks 450, two guide rail plates 460, two F-shaped buckles 470 and a lower plate lifting assembly.

[0046] The slide seat 410 is sleeved on the end of the insulating operating rod 300 , and its upper surface is used to carry the wire clamp 100 . The top of the rotating head 310 protrudes from the upper surface of the slide seat 410 and is used to cooperate with the plug-in portion 21 at the bottom of the metal threaded rod 20 .

[0047] The lower plate 420 is located below the slide seat 410 . A guide column 411 is fixed on the slide seat 410 . The lower plate 420 is slidably connected to the guide column 411 .

[0048] The inclined panel 430 is disposed on the lower panel 420 , and has two ends thereof with inclined surfaces facing outward and downward.

[0049] Two guide blocks 440 arranged opposite to each other are arranged on the slide seat 410 and are provided with a vertical first guide groove 441 .

[0050] Two L-shaped top blocks 450 are respectively arranged in the guide blocks 440 and can move along the first guide grooves 441, with the first transverse extensions 451 at the side ends thereof facing outward. It should be noted that the "outward" here refers to the direction toward the position between the two top blocks 450, and the "outward" hereinafter refers to the direction away from the position between the two top blocks 450.

[0051] Two guide rail plates 460 are arranged opposite to each other and are disposed on the slide seat 410 . A second transverse guide groove 461 is provided on the guide rail plates 460 .

[0052] Two F-shaped clips 470 are respectively arranged in the guide rail plate 460 and can move along the second guide groove 461. The second lateral extension portion 471 at the upper side protrudes from the upper surface of the slide seat 410 and faces inward, and is used to cooperate with the clamping portion 53 of the wire clamp 100. The third lateral extension portion 472 located at the lower side faces inward and cooperates with the first lateral extension portion 451, and its bottom faces the inclined surface of the inclined panel 430.

[0053] The lower plate lifting assembly is used to control the lower plate 420 to move upward along the guide column 411 .

[0054] The clamp 400 has a free state, a clamped state and a released state. Figure 4aAs shown, in the free state (no wire clamp 100 is placed), the top ends of the two top blocks 450 protrude from the upper surface of the slide seat 410, and the first transverse extension portion 451 abuts against the third transverse extension portion 472. Specifically, a spring is provided at the bottom of the two top blocks 450, the bottom of the spring abuts against the bottom of the first guide groove 441, and the top abuts against the top block 450, and the spring provides an upward elastic force to the top block 450, so that the top ends of the two top blocks 450 protrude from the upper surface of the slide seat 410. A spring is also provided on the outer side of the two buckles 470, one end of the spring abuts against the guide rail plate 460, and the top of the other end abuts against the buckle 470, and the spring provides an inward elastic force to the buckle 470, so that the third transverse extension portion 472 on the buckle 470 abuts against the first transverse extension portion 451 of the top block 450 (that is, the third transverse extension portion 472 clamps the first transverse extension portion 451).

[0055] like Figure 4b As shown, in the clamping state, the wire clamp 100 is placed on the upper surface of the slide seat 410 ( Figure 4b The wire clamp 100 is not shown), and the gravity of the wire clamp 410 causes the top ends of the two top blocks 450 to drop to be flush with the upper surface of the slide seat 410, and the first lateral extension portion 451 moves downward, and the third lateral extension portion 472 loses its restriction, so that the two buckles 470 move inward under the action of the spring, and then the second lateral extension portion 471 cooperates with the clamping portion 53 of the wire clamp 100 to clamp the wire clamp 100. At this time, the bottom of the buckle 470 just abuts against the inclined surface of the inclined panel 430 (the contact point is located at the upper part of the inclined surface), and the third lateral extension portion 472 is located above the first lateral extension portion 451.

[0056] like Figure 4c As shown, in the released state, the lower plate lifting assembly controls the lower plate 420 to move upward, that is, the inclined plate 430 moves upward, the inclined surface of the inclined plate 430 causes the buckle 470 to move outward, and the second transverse extension portion 471 is separated from the wire clamp 100 (that is, the wire clamp 100 is automatically released). After the wire clamp 100 leaves, the top block 450 moves upward under the action of the spring, so that the wire clamp 100 is subjected to a push-out force when it is separated, which can reduce the material jamming phenomenon. At this time, the top block 450 returns to its initial position (that is, the position in the free state, as shown in FIG. Figure 4a Then, the lower plate lifting assembly controls the lower plate 420 to return to the initial position (i.e., the lower plate 420 moves downward), and at this time, the buckle 470 returns to the initial position (i.e., the position in the free state, as shown in FIG. 1 ) under the action of the spring. Figure 4a shown).

[0057] Preferably, if Figure 6 As shown, the second lateral extension part 471, the third lateral extension part 472 and the bottom of the buckle 470 are provided with rollers. Thus, the second lateral extension part 471 and the clamping part 53 of the wire clamp 100 are in rolling contact, the third lateral extension part 472 and the first lateral extension part are in rolling contact, and the bottom of the buckle 470 and the inclined plate 430 are in rolling contact, thereby reducing the friction of the contact surface. Figure 5 As shown, an end surface of the first transverse extending portion 451 is provided with an arc-shaped groove matching the roller of the second transverse extending portion 471 , so that the second transverse extending portion 471 can clamp the first transverse extending portion 451 .

[0058] like Figure 6 , Figure 7 As shown, rollers are provided on the sides of the two buckles 470, and the guide rail plate 460 is also provided with a horizontal raceway matching the rollers. Rollers are provided on the sides of the two top blocks 450, and the guide block 440 is also provided with a vertical raceway matching the rollers. Thus, the buckles 470 and the top blocks 450 can move more smoothly.

[0059] In this embodiment, a wire clamp guide block 480 is provided on the upper surface of the slide seat 410 for positioning the wire clamp 100 so that the wire clamp 100 can be accurately placed.

[0060] In this embodiment, the clamp further includes a bottom bearing seat 490 fixed to the lower portion of the slide seat 410 to provide support for the rotating head 310 .

[0061] In this embodiment, the lower plate lifting assembly includes: a fixed pulley 510, which is arranged on the slide seat 401; a turntable 520, a bracket 530 is installed on the handheld torque meter 200, the turntable 520 is installed on the bracket 530 through a bearing clamp 540, and a handle 550 is installed on the side of the turntable 520; a rope 560, one end of which is wound and fixed on the turntable 520, and the other end is fixed to the lower plate 420 by passing around the fixed pulley 510. In this embodiment, a hand-cranked lower plate lifting assembly is used to control the upward movement of the lower plate 420, thereby controlling the opening and closing of the buckle 470. After the installation of the wire clamp 100, the wire clamp 100 can be detached by a single person handheld, thereby ensuring that the buckle 470 can be easily released when the slide seat 410 is not moving, and the wire clamp 100 can be smoothly detached. In other embodiments, the lower plate lifting assembly can also be used in other ways, which are not limited by the present invention.

[0062] The method of using the live installation tool provided by the present invention is: first, the clamp 400 is in a free state, the wire clamp 100 is placed on the upper surface of the slide seat 410, so that the wire clamp is converted into a clamping state, and the operator sends the wire clamp 100 to the position where it needs to be installed, and fixes the main conductor in the wire clamp 100 by controlling the handheld torque meter 200; then, the lower plate 420 is moved up through the lower plate lifting assembly, so that the clamp 400 releases the wire clamp 100.

[0063] In summary, the live installation tool for the wire clamp provided by the present invention can realize live installation operations directly on the pole, ensuring the safety and reliability of non-power outage operations, while simplifying the operating personnel and operating tools, improving work efficiency, and reducing equipment use costs.
