[0093] The specific implementation mode of the present invention will be described below in conjunction with the accompanying drawings and embodiments:

[0094] It should be noted that the structures, colors, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those who are familiar with this technology to understand and read, and are not used to limit the conditions under which the present invention can be implemented. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention.

[0095] At the same time, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "one end", "the other end", "middle part", "upper", "one side", "top", "inner", "front part", "center", "both ends", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0096] In addition, the terms "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third", "fourth" may explicitly or implicitly include at least one of such features.

[0097] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. Unless otherwise clearly limited, for those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0098] Such as Figures 1-3, the present invention provides an insulating hanging wire tool for live working on distribution networks. For the safety during live working, the whole device is made of insulating materials. The specific structure includes a first fixing member 1 and a second fixing member 2. The first fixing member 1 and the second fixing member 2 are connected by a connecting member 3. The first fixing member 1 and the second fixing member 2 can form a stable triangle. The first fixing member 1 and the second fixing member 2 are synchronously fixed on the pole tower. The wire is fixed at the bottom of the second fixing member 2. The wire is lifted through the pulley at the bottom of the second fixing member 2, so as to achieve the purpose of quickly detaching the wire from the insulator, enabling the operator to quickly install, remove and replace the insulator or cross arm.

[0099] Specifically, the first fixing member 1 includes a first clamp 1-1 and a first support rod 1-2. The first support rod 1-2 is fixed on the side of the first clamp 1-1. The first support rod 1-2 is fixed on the pole tower through a clamp. The second fixing member 2 includes a second clamp 2-1 and a second support rod 2-2. The second support rod 2-2 is fixed on the side of the second clamp 2-1. The second support rod 2-2 is fixed on the pole tower through the second clamp 2-1. The first support rod 1-2 and the second support rod 2-2 are connected by the connecting member 3, so that the first support rod 1-2, the second support rod 2-2 and the pole tower form a triangle. The first support rod 1-2 and the second support rod 2-2 serve as the main stress tools to determine the position of the pulley group 4-1 of the pulley block 4, and use the pulley block 4 to support and lift the wire, preventing the wire from being unable to be effectively fixed during live working, thus causing the problem of insufficient safety distance between wires due to swinging.

[0100] The first support rod 1-2 is connected to the connecting member 3 through a second rotating shaft 1-3, and the second support rod 2-2 is connected to the connecting member 3 through a third rotating shaft 2-3, so that both the first support rod 1-2 and the second support rod 2-2 are rotatably connected to the connecting member 3, and the position formed between the first support rod 1-2 and the second support rod 2-2 is adjustable. When the first support rod 1-2 and the second support rod 2-2 or one of them and its corresponding clamp are rotatably connected, the angle of the triangle formed by the first fixing member 1 and the second fixing member 2 can be adjusted, so that the floor area during transportation is smaller, which is convenient for carrying and transporting or fixing wires at different positions.

[0101] The first support rod 1-2 is connected to the connecting member 3 through a second rotating shaft 1-3, and the second support rod 2-2 is connected to the connecting member 3 through a third rotating shaft 2-3, so that the connection between the support rod and the connecting member 3 is detachable, which is convenient for transportation and later maintenance and replacement.

[0102] The connecting member 3 is connected with a pulley block 4, and the pulley block 4 is provided with a hook 5 for fixing a wire. After installing the device of the present invention on a pole tower, the wire is fixed on the hook 5, and a force is applied to the pulley block 4 to drive the wire to rise by the pulley block 4, so as to achieve the purpose of detaching the wire from the insulator, enabling the operator to safely remove or replace tower components such as insulators and cross arms.

[0103] As Figure 6 shown, as an embodiment of the device of the present invention, the pulley block 4 can select a movable pulley 4-2, and a hook 5 for fixing a wire is arranged on the side of the movable pulley 4-2. One end of an insulating rope 4-3 is directly fixed on the connecting member 3, and the other end is held by a worker. The insulating rope 4-3 is wound around a movable pulley 4-2. The worker stands on an insulating boom truck and manually pulls the insulating rope 4-3 to rise, driving the movable pulley 4-2 to rise, so that the wire fixed on the side of the movable pulley 4-2 by the hook 5 can also rise accordingly.

[0104] As Figure 5 shown, as an embodiment of the device of the present invention, the pulley block 4 can also select a fixed pulley 4-1. The fixed pulley 4-1 is fixed inside the connecting member 3, and the insulating rope 4-3 is wound around the circumference of the fixed pulley 4-1. One end of the insulating rope 4-3 is held by a worker, and a hook 5 for fixing a wire is arranged at the other end. The wire is fixed on the hook 5, and the worker stands on an insulating boom truck and manually pulls the insulating rope 4-3 to drive the wire to rise during the movement of the insulating rope 4-3.

[0105] As an embodiment of the device of the present invention, the pulley block 4 can also select a combination of a movable pulley 4-2 and a fixed pulley 4-1. The fixed pulley 4-1 is fixed inside the connecting member 3, and a hook 6 for fixing a wire is arranged on the movable pulley 4-2. The fixed pulley 4-1 and the movable pulley 4-2 are connected by an insulating rope 4-3. One end of the insulating rope 4-3 is fixed on the side of the connecting member 3 and wound around the circumferences of the movable pulley 4-2 and the fixed pulley 4-1, and the other end is held by a worker. During the process of the worker pulling the insulating rope 4-3, the movable pulley 4-2 is driven to rise, so that the wire connected to the movable pulley 4-2 rises accordingly.

[0106] An insulating pad is arranged inside the hook 5. The wire is heavy, and long-term hanging on the hook 5 may cause wear on the outer layer. Arranging an insulating pad inside the hook 5 can effectively prevent the wire from being worn and increase the service life of the wire.

[0107] Preferably, the insulating pad is made of rubber material. The rubber material has good deformability and can provide a large frictional force to ensure the stability of wire fixation.

[0108] The first hoop 1-1 and the second hoop 2-1 have the same structure. They are both fixed on the rod-shaped structure of the pole tower by the hoop structure to fix the support rod connected thereto.

[0109] Specifically, the first hoop 1-1 includes a first fixing plate 1-1-1 and a second fixing plate 1-1-2. The first fixing plate 1-1-1 and the second fixing plate 1-1-2 are arc-shaped plates. A first connecting ear 1-1-3 is provided at the end of the first fixing plate 1-1-1, and a second connecting ear 1-1-4 is provided at the end of the second fixing plate 1-1-2. Connecting holes 1-1-5 are provided on both the first connecting ear 1-1-3 and the second connecting ear 1-1-4. The first fixing plate 1-1-1 and the second fixing plate 1-1-2 are fixed by a first rotating shaft 1-2-4 passing through the connecting holes 1-1-5, and the first support rod 1-2 is fixed between the first connecting ear 1-1-3 and the second connecting ear 1-1-4.

[0110] Correspondingly, the second hoop 2-1 includes the same first fixing plate 1-1-1 and second fixing plate 1-1-2 as the first hoop 1-1, and the first fixing plate 1-1-1 and the second fixing plate 1-1-2 are also set as arc-shaped plates. The same connecting ears are provided at the ends of the first fixing plate 1-1-1 and the second fixing plate 1-1-2, and connecting holes 1-1-5 are provided on the connecting ears. The two fixing plates are also fixed by a first rotating shaft 1-2-4 passing through the connecting holes 1-1-5 on the connecting ears, so as to fix the second support rod 2-2 between the corresponding two connecting ears.

[0111] The first support rod 1-2 includes a first left support arm 1-2-1 and a first right support arm 1-2-2. The first hoop 1-1 connects the first left support arm 1-2-1 and the first right support arm 1-2-2. The second support rod 2-2 includes a second left support arm 2-2-1 and a second right support arm 2-2-2. The second hoop 2-1 connects the second left support arm 2-2-1 and the second right support arm 2-2-2, so that the first support rods 1-2 are provided on both sides of the first hoop 1-1, and the second support rods 2-2 are provided on both sides of the second hoop 2-1, providing a basis for lifting two wires at a time by the device of the present invention.

[0112] The same and corresponding support rods are provided on both sides of the first hoop 1-1 and the second hoop 2-1. Correspondingly, the connecting members 3 and the pulley groups 4 are also respectively provided on both sides of the hoops, so that the device of the present invention can lift two wires at a time, improving the use efficiency of the device of the present invention.

[0113] Correspondingly, the first connecting ear 1-1-3 includes a first left connecting ear 1-1-6 and a first right connecting ear 1-1-7, and the second connecting ear 1-1-4 includes a second left connecting ear 1-1-8 and a second right connecting ear 1-1-9. The first left support arm 1-2-1 is fixed between the first left connecting ear 1-1-6 of the first hoop 1-1 and the second left connecting ear 1-1-8 of the first hoop 1-1; the first right support arm 1-2-2 is fixed between the first right connecting ear 1-1-7 of the first hoop 1-1 and the second right connecting ear 1-1-9 of the first hoop 1-1; the second left support arm 2-2-1 is fixed between the first left connecting ear 1-1-6 of the second hoop 2-1 and the second left connecting ear 1-1-8 of the second hoop 2-1; the second right support arm 2-2-2 is fixed between the first right connecting ear 1-1-7 of the second hoop 2-1 and the second right connecting ear 1-1-9 of the second hoop 2-1. Thus, the four support arms are all fixed in their corresponding positions.

[0114] According to the above structure, the connector 3 is provided with corresponding left and right structures, including a left connector 3-1 connecting the first left support arm 1-2-1 and the second left support arm 2-2-1 and a right connector 3-2 connecting the first right support arm 1-2-2 and the second right support arm 2-2-2.

[0115] The device of the present invention is arranged in left and right groups. The first left support arm 1-2-1, the second left support arm 2-2-1 and the pole tower form a small triangle, and the first right support arm 1-2-2 and the second right support arm 2-2-2 form another triangle. Each of the two small triangles and their corresponding components fixes a wire, which improves the working efficiency of the device of the present invention while stably fixing the wire.

[0116] As Figure 4 shown, as an implementation manner of the device of the present invention, a first support rod 1-2 is welded between the first connecting ear 1-1-3 of the first hoop 1-1 and the second connecting ear 1-1-4 of the first hoop 1-1. A first connecting rod 1-2-3 is arranged between the first connecting ear 1-1-3 of the second hoop 2-1 and the second connecting ear 1-1-4 of the second hoop 2-1. The first connecting rod 1-2-3 is fixed by a first rotating shaft 1-2-4, and the connecting rod is threadedly connected to the second support rod 2-2.

[0117] The first support rod 1-2 is welded to the first clamp 1-1, making the angle between them non-adjustable to ensure the overall stability of the device and determine the shortest distance between the left and right conductors. The first connecting rod 1-2-3 is fixed by the first rotating shaft 1-2-4, enabling the first connecting rod 1-2-3 to rotate around the first rotating shaft 1-2-4. The second support rod 2-2 is threadedly connected to the first connecting rod 1-2-3, making the angle formed by the second support rod 2-2 and the first clamp 1-1 adjustable, so that the inclination angle of the connecting member 3 is adjustable, and thus the position of the fixed pulley 4-1 inside it is adjustable. The movement of the fixed pulley 4-1 causes the movable pulley 4-2 and the insulating rope 4-3 connected to it to move accordingly, adjusting the distance between the left and right conductors and preventing the problem of insufficient safety distance caused by the swing of the conductors during live working.

[0118] As an implementation mode of the device of the present invention, a second connecting rod 1-2-5 is provided between the first connecting ear 1-1-3 and the second connecting ear 1-1-4 of the first clamp 1-1 and between the first connecting ear 1-1-3 and the second connecting ear 1-1-4 of the second clamp 2-1, and the corresponding support rods are fixed through the second connecting ear 1-1-4.

[0119] Specifically, the second connecting rod 1-2-5 between the first connecting ear 1-1-3 and the second connecting ear 1-1-4 of the first clamp 1-1 is fixed by the first rotating shaft 1-2-4 of the first clamp 1-1, and the second connecting rod 1-2-5 between the first connecting ear 1-1-3 and the second connecting ear 1-1-4 of the second clamp 2-1 is fixed by the first rotating shaft 1-2-4 of the second clamp 2-1. After being fixed by the first rotating shaft 1-2-4, the second connecting rod 1-2-5 is threadedly connected to its opposite support rod, making the angles formed by the first support rod 1-2 and the second support rod 2-2 with their connecting clamps adjustable, adapting to conductors at different positions, and at the same time adjusting the distance between the left and right conductors to prevent the problem of insufficient safety distance between the conductors caused by the swing of the conductors.

[0120] The first support rod 1-2 and the first clamp 1-1, the second support rod 2-2 and the second clamp 2-1, the first support rod 1-2 and the connecting member 3, and the second support rod 2-2 and the connecting member 3 are all detachably connected through rotating shafts.
