[0002] When the 35kV-220kV overhead line tension string is a composite insulator, the length of the insulator and hardware is between 0.5-2.5m. When maintenance personnel need to work at the conductor end, they often step on the composite insulator for convenience. The skirt of the composite insulator is brittle, and dozens of insulator damage defects are found every year. In addition, the glass fiber of the composite insulator is not resistant to bending and can easily break under lateral force, causing the risk of line breakage and people falling from heights. Summary of the invention

[0003] In view of the above-mentioned problems existing in the existing auxiliary tools for preventing composite insulators from being stepped on, the present invention is proposed.

[0004] Therefore, the purpose of the present invention is to provide an auxiliary tool to prevent composite insulators from being stepped on. Its purpose is to provide a stable working platform so that workers can reach the working point smoothly without shaking during the operation, causing the workers to lose coordination, avoiding stepping on composite insulators, and ensuring line safety.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: comprising a main body of a U-shaped structure, one end of the main body is fixed to the conductor end, and the other end is fixed to the cross arm tower material.

[0006] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the part of the main body fixed to the wire end includes a first hook that can rotate 360 ​​degrees, a threaded hole is provided on one side of the first hook, a butterfly screw is installed in the threaded hole, and a spacer screw combination is installed at the other end.

[0007] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the first hook is closed and locked on the conductor, and the connecting part of the first hook is rotatably connected to the first cylinder by a round nut.

[0008] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the first cylinder is made of aluminum alloy with a length of 70 cm and a diameter of 2 cm.

[0009] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the lower end of the first cylinder is fixedly connected with two retractable thick tubes through a triangular joint, and the angle of the two thick tubes is adjusted through the triangular joint.

[0010] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the thick tube is composed of an inner tube and an outer tube, wherein the length of the outer tube is 1.7 m, and the adjustable length of the inner tube is 1.3 m.

[0011] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on, the other end of the thick tube is fixedly connected to the second cylinder through a nut, and the second cylinder is connected to the cross arm tower material.

[0012] As a preferred solution of the auxiliary tool for preventing composite insulators from being stepped on according to the present invention, the second cylinder is made of aluminum alloy material.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1

[0029] Reference Figures 1-2 , which is the first embodiment of the present invention, provides an auxiliary tool for preventing composite insulators from being stepped on. The device includes a main body 100 of a U-shaped structure, one end of the main body 100 is fixed to the conductor end, and the other end is fixed to the cross arm tower material.

[0030] Specifically, the part of the main body 100 fixed to the wire end includes a first hook 101 that can rotate 6 degrees. A threaded hole is opened on one side of the first hook 101, and a butterfly screw is installed in the threaded hole. A spacer screw assembly is installed at the other end.

[0031] Furthermore, the first hook 101 is closed and locked on the wire, and the connecting part of the first hook 101 is rotatably connected to the first cylinder 102 by a round nut. The first cylinder 102 is an aluminum alloy with a length of 70 cm and a diameter of 2 cm.

[0032] The design of the U-shaped body 100 provides good stability and is easy to operate. Specifically, one end of the device is fixed to the conductor end, and the other end is fixed to the cross arm tower material. This arrangement allows the entire device to form a stable support structure between two key points, thereby providing a reliable working platform for maintenance personnel.

[0033] At the wire end, the device is equipped with a first hook 101 that can rotate 360 ​​degrees. The hook can rotate freely according to actual needs so as to be more flexibly hooked on the wire. A threaded hole is provided on one side of the first hook 101, and a butterfly screw is installed inside. The design of this screw is convenient for tightening or loosening by hand without the need for additional tools, which increases the convenience of use. In addition, a set of spacer screws is also assembled at the other end of the first hook 101. A blocking piece is fixed at the other end of the spacer screw to block the opening at the first hook 101, ensuring the safety and reliability of the device.

[0034] When the first hook 101 is closed and locked on the wire, it is connected to the first cylinder 102 through a round nut. This cylinder is made of aluminum alloy, with a length of 70 cm and a diameter of 2 cm. The reason for choosing aluminum alloy as the material is that it is both light and strong enough to withstand the various stresses that may be encountered during the operation. Such material properties are crucial to reducing the overall weight of the device, while also ensuring sufficient load-bearing capacity, which is crucial to ensure the safety of maintenance personnel.

[0035] In summary, through such a structural design, the device not only provides the necessary stability and reduces the shaking during the operation, but also greatly simplifies the installation and disassembly process and enhances the flexibility of use. At the same time, the lightweight aluminum alloy material reduces the operating burden of the staff and makes long-term high-altitude operations easier. Overall, this invention effectively solves the deficiencies in the prior art and improves the safety and efficiency of power maintenance operations.

[0036] Example 2

[0037] Reference Figures 1 to 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the lower end of the first cylinder 102 is fixedly connected with two telescopic thick tubes 200 through a triangular joint, and the two thick tubes 200 are adjusted at an angle through the triangular joint.

[0038] Furthermore, the thick tube 200 is composed of an inner tube and an outer tube, wherein the length of the outer tube is 1.7 m, the adjustable length of the inner tube is 1.3 m, the other end of the thick tube 200 is fixedly connected to the second cylinder 104 through a nut, and the second cylinder 104 is connected to the cross arm tower material, and the second cylinder 104 is made of aluminum alloy.

[0039] Furthermore, the second cylinder 104 has the same length as the first cylinder 102 hung on the wire end, and one end of the second cylinder 104 is hinged with a second hook 105, and the number of the second hooks 105 is two. One end of the second hook 105 is provided with a threaded hole, and a butterfly screw is installed in the threaded hole.

[0040] When in use, the lower end of the first cylinder 102 is fixedly connected to two telescopic thick tubes 200 through a triangular joint, and the two thick tubes 200 can adjust the angle between each other through the triangular joint. Such a design not only brings additional stability to the entire structure, but also enables the device to adapt to different working environments and angles, thereby increasing its scope of application and flexibility.

[0041] Each thick tube 200 consists of an inner tube and an outer tube. The outer tube is fixed at 1.7 meters in length, while the inner tube can be extended and retracted as needed, with a maximum adjustable length of 1.3 meters. Such a telescopic mechanism gives the device excellent adjustability, allowing it to adapt to various length requirements and thus be better applied to actual work scenarios. By adjusting the length of the thick tube 200, operators can easily adjust the height and span of the support frame according to specific working conditions to ensure the stability and safety of the work platform.

[0042] The other end of the thick tube 200 is fixedly connected to the second cylinder 104 through a nut, and the second cylinder 104 is responsible for connecting to the cross arm tower material. The second cylinder 104 is also made of aluminum alloy, and its length and specifications are consistent with the first cylinder 102 at the wire end. The use of aluminum alloy material not only reduces the total weight of the device, but also ensures sufficient mechanical strength to enable it to withstand various loads during operation. This lightweight design helps to reduce the physical burden of operators during handling and installation, and also improves work efficiency.

[0043] Furthermore, two second hooks 105 are hingedly connected to one end of the second cylinder 104, and each of the second hooks 105 has a threaded hole at one end, and a butterfly screw is installed in the threaded hole. Such a hook design allows them to rotate freely as needed and be firmly locked on the crossarm tower material. The use of butterfly screws once again emphasizes the convenience of operation, because they can be easily tightened or loosened manually without any special tools. This quick and easy fixing method not only speeds up the installation process, but also ensures the stability of the device during operation and reduces the risk of accidental loosening.

[0044] In summary, the device not only enhances the stability of the working platform through its well-designed components and structure, but also greatly improves the safety and efficiency of the operation through its high adjustability and lightweight material selection. At the same time, the simple installation and disassembly process makes this set of auxiliary tools an indispensable part of power maintenance work.

[0045] Example 3

[0046] Reference Figures 1 to 3 , which is the third embodiment of the present invention.

[0047] The operation process of the device is as follows: First, one end of the auxiliary tool, that is, the part with the first hook 101, is hooked to the end of the wire. The first hook 101 is designed to rotate 360 ​​degrees and can be closed and locked on the wire by a combination of a butterfly screw and a spacer screw. This design not only facilitates the quick and accurate positioning of the hook, but also ensures that it is firmly fixed to prevent loosening or slipping during operation. Once the hook is correctly hooked and locked, it is connected to a 70 cm long and 2 cm diameter aluminum alloy first cylinder 102 through a round nut, which lays a solid foundation for the next installation steps.

[0048] Next, adjust the length of the two retractable thick tubes 200. The two thick tubes 200 are connected to the lower end of the first cylinder 102 through a triangular joint, and their angle can also be adjusted through this joint. The thick tube 200 consists of two layers of inner and outer tubes. The outer tube is 1.7 meters long and the inner tube is retractable, with a maximum adjustable length of up to 1.3 meters. This telescopic mechanism enables the entire tool to adapt to a variety of different working heights and distances, enhancing its practicality. By adjusting the length and angle of the thick tube 200, the best working position can be obtained according to the actual situation, ensuring that the support provided by the tool is both stable and comfortable.

[0049] Subsequently, the other end of the thick tube 200 is fixed to the second cylinder 104 by a nut, and the cylinder is connected to the cross arm tower material. The second cylinder 104 is also made of aluminum alloy, and its length and diameter are the same as the first cylinder 102. Such consistency ensures the balance and stability of the entire structure. One end of the second cylinder 104 is equipped with a rotatable second hook 105, which is also provided with a butterfly screw for fastening it to the cross arm tower material. The presence of two hooks increases the stability of the connection between the tool and the tower material, and further reduces the shaking of the tool during use.

[0050] After completing the above steps, the entire auxiliary tool forms a stable support structure from the conductor end to the crossarm tower material. At this time, use this structure as a support platform to safely carry out aerial work. Because the tool is designed with the actual needs of the operators in mind, it not only provides stable support, but also significantly reduces the risk of operators stepping on fragile composite insulators, thereby avoiding potential safety hazards such as line disconnection accidents or personnel falls caused by insulator damage.

[0051] In short, this auxiliary tool provides an efficient and safe solution for high-altitude maintenance work on power systems through its carefully designed structure and components. It simplifies the preparation process before the operation, reduces the operation time and labor intensity, and greatly improves the safety factor of the operation. The choice of lightweight aluminum alloy material reduces the overall weight, making the tool easy to carry and operate. Overall, this tool significantly improves the working conditions of high-altitude operations and is an important innovation in the power industry.
