Description

Technical Field

[0001] This utility model relates to the field of potential tool technology, specifically a potential tool along a tension insulator string. Background Technology

[0002] Tension insulator strings are crucial components in the erection of power transmission lines. They mainly include three types: porcelain insulator strings, glass insulator strings, and composite tension insulator strings. The former two consist of two or more insulator pieces combined together. Their function is to support the conductor and control its tension and insulation. Currently, in tower stringing operations, guy wires are used to stabilize the towers, operating on the principle of leverage. The guy wires balance the forces acting on the pole and resist wind pressure, preventing the pole from toppling. However, without auxiliary potential tools during tower stringing, it can be difficult for power construction personnel to access the electric field. Furthermore, while auxiliary potential tools are used, different tower models require different tools, leading to ineffective installation and reduced effectiveness of the tools along the tension insulator strings.

[0003] Therefore, it is necessary to develop a potential tool along the tension insulator string. Utility Model Content

[0004] The purpose of this invention is to provide a potential tool along a tension insulator string to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a potential tool along a tension insulator string, comprising an insulating crossbar, one end of which is rotatably connected to an insulating side bar A;

[0006] The other end of the insulating crossbar is rotatably connected to an insulating side bar B.

[0007] Preferably, the bottom end of the insulating side rod A is rotatably connected to a crossarm side clamp, and the front and rear ends of the crossarm side clamp are provided with sliding grooves on the lower surface of the crossarm side clamp.

[0008] Preferably, a retaining element is installed inside the slide groove, and the outer wall of the retaining element is slidably connected to the inside of the slide groove.

[0009] Preferably, a nut is installed on one side of the outer wall of the card, and the inside of the nut is threadedly connected to one side of the outer wall of the card.

[0010] Preferably, a hanging ring is installed on the upper part of the outer wall of the insulating side rod B, and a threaded groove is formed at the center of the lower surface of the insulating side rod B.

[0011] Preferably, a wire-side clamp is installed at the bottom end of the insulating side rod B, and a screw is installed on one side of the top of the wire-side clamp.

[0012] Preferably, the outer wall of the screw is threaded to the inner wall of the threaded groove, and an installation hole is provided on one side below the surface of the wire-side clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By connecting the crossarm side clamp to the insulating crossbar via a rotatable connection and fixing it at an angle with fastening bolts, the crossarm side clamp is inserted into the corresponding position on the iron tower. The clamp is then tightened with nuts according to the adjustable length of the clamp. The adjustable length clamp is applicable to different types of iron towers, minimizing the possibility of installation failure due to incompatibility with different types of iron towers. This effectively improves the applicability of the potential tool along the tension insulator string.

[0015] By connecting the conductor-side clamp to the insulating crossbar via a rotatable connection from the insulating side bar B, and fixing it at an angle with fastening bolts, and reliably connecting the conductor-side clamp to the U-shaped ring on the tension insulator string, a potential tool is formed after the entire assembly is installed. This allows live-line workers to easily enter the electric field to perform corresponding operations by holding the tool, minimizing the possibility of difficulty in entering the electric field due to the lack of corresponding auxiliary potential tools on the tower. It also increases the safety of live-line workers and effectively improves the usability of the potential tool along the tension insulator string. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution: a potential tool along a tension insulator string, please refer to [link / reference]. Figures 1-4 The device includes an insulating crossbar 1, with an insulating side bar A2 rotatably connected to one end of the insulating crossbar 1. A crossarm side clamp 201 is rotatably connected to the bottom end of the insulating side bar A2. Sliding grooves 202 are provided at the front and rear ends of the surface of the crossarm side clamp 201. A clamp 203 is installed inside the sliding groove 202. The outer wall of the clamp 203 is slidably connected to the inside of the sliding groove 202. A nut 204 is installed on one side of the outer wall of the clamp 203. The inside of the nut 204 is threadedly connected to one side of the outer wall of the clamp 203. The crossarm side clamp 201 is rotatably connected to the insulating crossbar 1 by the insulating side bar A2 and is fixed at an angle by a fastening bolt. The crossarm side clamp 201 is then inserted into the corresponding position on the iron tower. The clamp 203 is adjustable in length and is tightened with the nut 204. The adjustable length clamp 203 can be used to fit different types of iron towers, thus avoiding the situation where it cannot be installed due to incompatibility with different types of iron towers.

[0023] An insulating side rod B3 is rotatably connected to the other end of the insulating crossbar 1. A hanging ring 301 is installed on the upper part of the outer wall of the insulating side rod B3. A threaded groove 302 is opened at the center of the lower surface of the insulating side rod B3. A conductor side clamp 303 is installed at the bottom end of the insulating side rod B3. A screw 304 is installed on one side of the top of the conductor side clamp 303. The outer wall of the screw 304 is threadedly connected to the inner wall of the threaded groove 302. An installation hole 305 is opened on one side of the lower surface of the conductor side clamp 303. The conductor side clamp 303 is rotatably connected to the insulating crossbar 1 by the insulating side rod B3 and is fixed at an angle by a fastening bolt. The conductor side clamp 303 is reliably connected to the U-shaped ring on the tension insulator string. At the same time, the conductor side clamp 303 is installed in the threaded groove 302 on the insulating side rod B3 by the screw 304, so that the conductor side clamp 303 is screwed in, achieving the effect of height adjustment.

[0024] Working principle: When using this utility model, the crossarm side clamp 201 is connected to the insulating crossbar 1 via a rotatable connection from the insulating side bar A2, and is fixed at an angle by fastening bolts. The crossarm side clamp 201 is then inserted into the corresponding position on the tower. The adjustable-length clamp 203, combined with a nut 204, is tightened for fixation. The adjustable-length clamp 203 is applicable to different types of towers, minimizing the possibility of installation failure due to incompatibility with different tower types. This effectively improves the applicability of the potential tool along the tension insulator string. The conductor side clamp 303 is connected to the insulating crossbar 1 via a rotatable connection from the insulating side bar B3, and is fixed at an angle by fastening bolts. The angle is fixed by bolts, and the conductor-side clamp 303 is reliably connected to the U-shaped ring on the tension insulator string. After the whole assembly is installed, it forms a potential tool, which makes it convenient for live-line workers to enter the electric field to carry out corresponding operations. This avoids the situation where it is difficult to enter the electric field due to the lack of corresponding auxiliary potential tools on the iron tower, and also increases the safety of live-line workers. At the same time, the conductor-side clamp 303 is installed in the threaded groove 302 on the insulating side rod B3 by means of a screw 304, so that the height of the conductor-side clamp 303 is adjustable when screwed in, which effectively improves the use of the potential tool along the tension insulator string.
