[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example: See Figure 1-4 This utility model discloses an F-type steel pipe pole for overhead transmission lines, comprising multiple connecting pipe poles 1 interconnected by connecting flanges 2. Each connecting pipe pole 1 has a connecting flange 2 at both ends. One end of each connecting pipe pole 1 is connected to a mounting cover plate 8 via the connecting flange 2. Multiple connecting bolts 10 pass through the mounting cover plate 8 and the connecting flange 2. The connecting flange 2 is made of Q345B low-alloy high-strength structural steel, which has high strength and good toughness. When used with the connecting pipe pole 1, it facilitates the rapid splicing and disassembly of various sections of the steel pipe pole, significantly improving construction efficiency. The mounting cover plate 8 is fastened to the connecting flange 2 via connecting bolts 10, enhancing the sealing and structural stability of the top of the steel pipe pole, effectively preventing rainwater and foreign object intrusion, while also improving the overall structure's wind and earthquake resistance, ensuring the long-term stable operation of the transmission line. A crossarm unit 9 is provided on one side of each connecting pipe pole 1, and a crossarm assembly frame 6 is fixedly connected to one end of the crossarm unit 9. The crossarm assembly frame 6 has multiple bolt mounting holes 7 evenly spaced. The crossarm unit 9 is made of hot-dip galvanized angle steel, which has strong corrosion resistance. It works in conjunction with the crossarm assembly frame 6 and the bolt mounting holes 7 to facilitate the flexible installation of insulator strings, conductor fittings and other equipment according to the needs of different transmission lines, thereby improving the adaptability of the device. The multiple bolt mounting holes 7 can precisely adjust the installation angle and position of the crossarm to ensure that the conductor erection meets the safety distance and electrical insulation standards, effectively meeting the installation needs of diverse transmission lines. A fixed mounting rod 4 is provided on one side of the connecting pipe pole 1. The two ends of the fixed mounting rod 4 are fixedly connected to the connecting flange 2. The fixed mounting rod 4 is made of seamless steel pipe and is fixed by welding to the connecting flange 2, which enhances the lateral support strength of the steel pipe pole and improves the overall structural rigidity. It works in conjunction with the connecting pipe pole 1 to effectively disperse external forces such as wind load and conductor tension, significantly improving the wind resistance and overturning resistance of the steel pipe pole, and enabling it to better adapt to complex and changeable natural environments.
[0019] In this utility model, multiple fixed connecting sleeves 5 are fixedly mounted on the fixed mounting rod 4 via a first pin. The fixed connecting sleeves 5 are made of aluminum alloy, which is lightweight and high-strength. They are connected to the fixed mounting rod 4 via the first pin, facilitating flexible adjustment of the installation position according to maintenance needs. This design enables quick disassembly and reassembly and position adjustment of the fixed connecting sleeves 5, providing convenience for installing auxiliary facilities such as climbing frames 3 and maintenance platforms, and improving the flexibility and convenience of high-altitude operations. A second pin is provided at one end of the fixed connecting sleeve 5, and the climbing frame 3 is inserted into the fixed connecting sleeve 5 at the second pin. Multiple climbing poles 11 are staggered and fixed on the climbing frame 3. The climbing frame 3 is made of high-strength aluminum alloy and is inserted into the fixed connecting sleeves 5 via the second pin, facilitating quick installation. The design allows for easy disassembly and maintenance by staff, facilitating access to the equipment for high-altitude inspections. The staggered arrangement of the climbing poles 11 increases the points of leverage during climbing, enhancing safety and comfort. The detachable design does not compromise the overall aesthetics and structural strength of the steel pipe poles, effectively solving the problems of inconvenient installation and aesthetic impact associated with traditional climbing equipment. The climbing frame 3 is divided into multiple sections, with second pins inserted and fixed at both ends of each section. This multi-section design, connected by second pins, allows for flexible adjustment of the climbing frame length based on the height of the steel pipe poles. During transportation and installation, it can be disassembled into smaller components, reducing transportation difficulty and installation costs. Furthermore, the independent connection of each section enhances the overall stability of the climbing frame, meeting the maintenance needs of power transmission lines at different heights and improving the versatility and practicality of the device.
[0020] Working Principle: When using this utility model, during on-site assembly, the construction unit first places the bottom connecting pipe rod 1 in the predetermined position and uses lifting equipment to maintain stability. Adjacent connecting pipe rods 1 are then sequentially spliced together using the connecting flange 2. The bolt holes on the flange are aligned, and the connecting bolts 10 are inserted and initially tightened with a wrench to ensure the pipe rod connections are aligned and without significant misalignment. This operation is repeated until all connecting pipe rods 1 are spliced to the designed height. Subsequently, on the fixed installation rod 4, according to maintenance needs, the fixed connecting sleeve 5 is installed on the fixed installation rod 4 using the first pin, and then the second pin is inserted into the fixed connecting sleeve 5 to fix the climbing frame 3 to it. This is achieved through multiple sections... The climbing frame 3 is assembled to form a complete climbing structure. Both ends of each section of the climbing frame 3 are securely connected to the fixed connecting sleeve 5 through the second pin, ensuring that the climbing frame 3 is firmly and reliably installed. Then, the crossarm unit 9 is installed on one side of the connecting pipe pole 1, aligning the bolt mounting holes 7 on the crossarm assembly frame 6 with the pre-drilled mounting holes on the connecting pipe pole 1. Bolts are inserted and tightened to complete the fixing of the crossarm unit 9. Finally, the mounting cover plate 8 is installed on the top of the connecting pipe pole 1 through the connecting flange 2. Multiple connecting bolts 10 are used to fasten the mounting cover plate 8 to the connecting flange 2, ensuring that the top of the steel pipe pole is sealed and the connection is stable. This completes the on-site assembly work of the F-type steel pipe pole for overhead transmission lines.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
