[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment: a special foot nail for climbing work on an electric tower, comprising a nail body 1 and a triangular steel plate 2. The top of the nail body 1 is provided with a friction groove 3. The friction groove 3 here is used to increase the friction between the hook lock used by the staff to prevent accidental falling off, thereby improving safety. The right side of the nail body 1 is fixedly connected with a fixing component for providing a connection function. The fixing component includes a side column 4. The left side of the side column 4 is fixedly connected to the right side of the nail body 1. The nail body 1 here provides a stable support for the side column 4. The right side of the side column 4 contacts the left side of the triangular steel plate 2. The right side of the side column 4 is fixedly connected with a plug column 5. The outside of the plug column 5 is slidably connected to the inner wall of the triangular steel plate 2. The plug column 5 here is a cube, which ensures that it will not be distorted when inserted into the inner wall of the triangular steel plate 2 and remains stable.

[0032] The right side of the plug column 5 is fixedly connected to a sliding column 6, and the outer part of the sliding column 6 is slidably connected to the inner wall of the triangular steel plate 2. The inner wall of the fixed component is rotatably connected to the rotating shaft 7. The sliding column 6 here provides stable support for the rotating shaft 7, and the outer part of the rotating shaft 7 is slidably connected to a rotating block 8. The bottom end of the rotating block 8 is fixedly connected to a locking component for providing a locking effect. The locking component includes a counterweight block 9. Compared with other physical structures, the counterweight block 9 here is heavier and has the effect of keeping the locking state stable. The top of the counterweight block 9 is fixedly connected to the bottom end of the rotating block 8, and the outer part of the counterweight block 9 is slidably connected to the inner wall of the sliding column 6. When it is necessary to install this foot nail, first insert the nail body 1 into the inner wall of the triangular steel plate 2. At this time, because the shape of the insertion column 5 is square, it can be directly engaged with the triangular steel frame. After the insertion is completed, the rotating block 8 here will rotate under the action of the counterweight block 9 (the counterweight block 9 here is the heavier part compared to other physical structures), thereby forming a vertical relationship with the sliding column 6, and the assembly of the foot nail is completed.

[0033] Reference Figure 1 and Figure 4 , the top of the inner wall of the nail body 1 is fixedly connected with a durable layer 10, and the material of the durable layer 10 here is high-strength manganese steel, which is known for its excellent strength and durability. It can withstand large loads and impacts, providing a solid structural foundation for the entire foot nail. The bottom end of the durable layer 10 is fixedly connected with a heat-resistant layer 11, and the material of the heat-resistant layer 11 here is modified epoxy resin. The modified epoxy resin improves the original epoxy resin through chemical or physical methods to enhance the heat resistance of this foot nail. The outside of the heat-resistant layer 11 is fixedly connected to the inner wall of the nail body 1, and the bottom end of the heat-resistant layer 11 is fixedly connected with an insulating layer 12, and the material of the insulating layer 12 here is phenolic resin, and its electrical insulation also ensures the safety of the foot nail when used near electrical equipment. The outside of the insulating layer 12 is fixedly connected to the inner wall of the nail body 1;

[0034] The bottom end of the insulating layer 12 is fixedly connected to a wear-resistant layer 13. This layer is made of chlorinated rubber, known for its excellent chemical stability and wear resistance. It is resistant to a variety of chemical substances, including acids, alkalis, and salts. The outer portion of the wear-resistant layer 13 is fixedly connected to the inner wall of the nail body 1. The bottom end of the wear-resistant layer 13 is fixedly connected to a weather-resistant layer 14. This weather-resistant layer 14 is made of alkyd resin, which has excellent weather resistance and mechanical properties. It can resist the influence of environmental factors such as ultraviolet rays and temperature changes. The outside of the weather-resistant layer 14 is fixedly connected to the inner wall of the nail body 1. The above five material layers effectively improve the cold resistance, insulation and weather resistance of this foot nail, thereby increasing the service life of this foot nail. A hook 15 is provided on the inner wall of the nail body, and two hook ropes 16 are fixedly connected to the bottom end of the hook 15. The hook 15 and the hook rope 16 here are fixed on the body of the staff. When the staff is climbing the power tower, the hook 15 can be used to hang on the inner wall of the nail body 1 to prevent accidental falling.

[0035] Working principle: First, insert the nail body 1 into the inner wall of the triangular steel plate 2. Since the shape of the plug 5 is square, it can be directly engaged with the triangular steel frame, ensuring the stability and safety of the foot nail.

[0036] Next, the rotating block 8 rotates under the action of the counterweight 9, forming a perpendicular relationship with the sliding column 6, completing the installation of the foot spike. This step utilizes the weight of the counterweight 9 to maintain the stability of the locked state, ensuring that the foot spike will not accidentally fall off during use. It is also used in conjunction with the hook 15 and hook rope 16. When climbing the iron tower, workers can first fasten the hook rope 16 to their body and then hang the hook 15 on the inner wall of the nail body 1 to prevent accidental falls and improve safety.

[0037] Inside the nail body 1, five layers of different materials are arranged in sequence from top to bottom. The first is the durable layer 10, which is made of high-strength manganese steel, providing a solid structural foundation and withstanding large loads and impacts. The second is the heat-resistant layer 11, which is made of modified epoxy resin to enhance the heat resistance of the nail. Then there is the insulating layer 12, which uses phenolic resin material to ensure electrical insulation, allowing the nail to be safely used near electrical equipment. Next is the wear-resistant layer 13, which is made of chlorinated rubber, has good chemical stability and wear resistance, and can resist corrosion from a variety of chemicals. Finally, there is the weather-resistant layer 14, which uses alkyd resin and has excellent weather resistance and mechanical properties, and can resist the influence of environmental factors such as ultraviolet rays and temperature changes.

[0038] This five-layer design not only improves the overall performance of the spikes, but also extends their service life, enabling them to operate reliably in a variety of complex environments. This structural and material configuration significantly enhances the safety of high-altitude operations on power towers.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
