[0002] Steel pipe pole structures for power line erection are tall steel structures used to support power or communication lines. They are typically made of high-strength steel and feature a circular cross-section and hollow tubular design. They are assembled by welding or bolting and possess excellent load-bearing capacity and resistance to wind and earthquakes. Steel pipe pole structures can be customized in height and diameter according to actual needs. They are widely used in power transmission lines, communication base stations, streetlights, and other fields, effectively supporting conductors and equipment while occupying little space and facilitating installation and maintenance.

[0003] During the installation of steel pipe poles, since they mostly adopt a multi-segment structure, it is necessary to align the axes of each segment during connection. If the axes are not aligned accurately, it may lead to structural instability, thereby affecting its load-bearing capacity and wind and earthquake resistance. Existing technologies usually require the assistance of external tools for alignment, which not only increases the difficulty of operation for workers but also places high demands on technical precision, making it difficult to ensure the final installation quality. Therefore, a steel pipe pole structure for line erection is proposed to address the above problems. Utility Model Content

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.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Please see Figure 1-8 This utility model provides a technical solution:

[0031] A steel pipe pole structure for power line erection includes a first steel pipe pole assembly 1, with a second steel pipe pole assembly 2 bolted to the lower end of the first steel pipe pole assembly 1. A guide assembly 3 is rotatably connected to the lower end of the first steel pipe pole assembly 1. The first steel pipe pole assembly 1 includes a first steel pipe pole body 11, with a first flange 12 fixedly connected to the lower end of the first steel pipe pole body 11. A limiting groove 14 is formed inside the first flange 12. The second steel pipe pole assembly 2 includes a second steel pipe pole body 21, with a second guide assembly 3 fixedly connected to the top end of the second steel pipe pole body 21. Flange 22, the inner side of the second flange 22 is provided with a tapered groove 24 and a guide groove 25. The guide assembly 3 includes a limiting rotating ring 31. A fixing ring 32 is fixedly connected to the inner side of the limiting rotating ring 31. An embedded arc plate 33 and a load-bearing arc plate 34 are fixedly connected to the bottom end of the fixing ring 32. A wheel hole 35 is provided on the inner side of the embedded arc plate 33. A bearing 36 is fixedly connected to the inner side of the wheel hole 35. A shaft column 37 is fixedly connected to the inner side of the bearing 36. A roller 38 is fixedly connected to the outer side of the shaft column 37. The limiting rotating ring 31 is rotatably connected inside the limiting rotating groove 14.

[0032] As a further implementation of this solution, a base 4 is fixedly connected to the bottom end of the second steel pipe rod body 21. A second fixing hole 23 is opened on the inner side of the second steel pipe rod body 21, and a first fixing hole 13 is opened on the inner side of the first flange 12. The inner sides of the first steel pipe rod body 11 and the first flange 12 are hollow structures. The limiting groove 14 is connected to the inner side of the first flange 12. The fixing ring 32 protrudes from the lower end of the first flange 12. Through the above settings, a stable bottom support is provided for the device, ensuring that the device will not tilt or shift due to external forces during installation. At the same time, the first fixing hole 13 and the second fixing hole 23 can be used to fix the first flange 12 and the second flange 22 with bolts.

[0033] As a further implementation of this scheme, the bottom end of the first flange 12 is fitted with the top end of the second flange 22. The embedded arc plate 33 and the load-bearing arc plate 34 are embedded in the conical groove 24. The bottom end of the embedded arc plate 33 protrudes from the lower end of the conical groove 24. The roller 38 and the shaft 37 are embedded in the inner side of the wheel hole 35. The roller 38 protrudes from the outer side of the wheel hole 35. The lower end of the embedded arc plate 33 protrudes from the lower end of the load-bearing arc plate 34. The bottom end of the load-bearing arc plate 34 is flush with the bottom end of the conical groove 24. Through the above settings, the design of the embedded arc plate 33 and the load-bearing arc plate 34 being embedded in the conical groove 24 enables the device to achieve precise positioning and alignment during the connection process, effectively avoiding installation errors caused by component misalignment. The design of the bottom end of the embedded arc plate 33 protruding from the lower end of the conical groove 24 allows the roller 38 to move away from the conical groove 24 after the embedded arc plate 33 enters the guide groove 25, ensuring stability after installation.

[0034] As a further implementation of this scheme, the tops of the load-bearing arc plate 34 and the embedded arc plate 33 are flush with the top of the second flange 22, and the outer side of the load-bearing arc plate 34 is in contact with the inner side of the conical groove 24. Through the above settings, the guide assembly 3 is effectively prevented from loosening or falling off during installation. The flush design makes it convenient for the embedded arc plate 33 and the load-bearing arc plate 34 to be installed inside the second steel pipe pole body 21. The fit between the load-bearing arc plate 34 and the conical groove 24 improves the stability of the load-bearing capacity of the first steel pipe pole assembly 1.

[0035] As a further implementation of this solution, the tapered groove 24 is cone-shaped and extends through the inner side of the second flange 22. The guide groove 25 is inclined, and the embedded arc plate 33 is partially embedded in the guide groove 25. Through the above settings, the device can achieve better guidance and alignment during installation. The inclined structure design of the guide groove 25 allows the embedded arc plate 33 to be more smoothly embedded in the guide groove 25, improving installation efficiency and accuracy.

[0036] Workflow: During device installation, firstly, the base 4 is fixed to the ground foundation with bolts. Then, the first steel pipe rod body 11 is hoisted using a crane to ensure it is vertical. The first flange 12 and the second flange 22 are brought close together. The embedded arc plate 33 is rotated, causing the limiting rotating ring 31 and the fixing ring 32 to rotate. The limiting rotating ring 31 is rotatably connected to the inner side of the limiting rotating groove 14, which can prevent the guide assembly 3 from colliding with the first steel pipe rod assembly 1. The rollers detach from the guide groove 25, aligning the embedded arc plate 33 with the guide groove 25. As the first steel pipe rod body 11 falls, the roller 38 contacts the inner side of the guide groove 25, at which point the roller 38 drives the shaft 37 to rotate. The shaft 37 is rotatably connected to the inner side of the wheel hole 35 via the bearing 36. The diameter of the embedded arc plate 33 is larger than the diameter of the load-bearing arc plate 34. The roller 38 reduces the resistance generated during the installation of the first steel pipe rod body 11. The roller 38 then fixes the first steel pipe rod body 11 within the guide groove 25. The device serves to guide the position of the first steel pipe pole body 11. After the first steel pipe pole body 11 falls to a certain distance, the embedded arc plate 33 is located inside the guide groove 25. When the first flange 12 and the second flange 22 are fitted together, the load-bearing arc plate 34 is fitted with the inner side of the conical groove 24. At this time, the embedded arc plate 33 extends out of the lower end of the conical groove 24. Through the setting of the load-bearing arc plate 34 and the conical groove 24, the contact area between the second steel pipe pole body 21 and the first steel pipe pole body 11 can be increased, thereby improving the stability of the load-bearing capacity of the second steel pipe pole body 21 on the first steel pipe pole body 11. At the same time, after the device is installed, it can ensure that the axis of the first steel pipe pole body 11 is aligned with the axis of the second steel pipe pole body 21. Through the above working principle, the device can align the axis of the first steel pipe pole body 11 with the axis of the second steel pipe pole body 21 without the need for external tools during installation, reducing the difficulty of operation and the technical requirements for workers, and improving the final installation quality.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
