[0002] Concrete poles are commonly used for erecting high-voltage lines. They include tapered concrete poles and equal-diameter concrete poles. Compared to equal-diameter concrete poles, tapered concrete poles can fully utilize the mechanical properties of the material and have good stability. Detachable tapered concrete flange poles are a type of component that combines the characteristics of flange connection structures and tapered concrete poles. The flange is usually welded to the bottom of the pole and fixed to the embedded parts in the concrete foundation by bolts, thus achieving a detachable connection.

[0003] In the existing process of installing cement poles via flanges, after the cement pole is erected, the flange holes on the cement pole flange need to be aligned with the flange holes on the embedded parts. To ensure a stable connection, the bolts are usually tightened gradually in a diagonal manner after alignment. During this process, manual adjustment is required to stabilize the cement pole and prevent positional deviation, which is quite laborious and affects installation efficiency. Furthermore, if the flange surface is uneven, it is difficult for the flanges to fit tightly together, affecting the stability of the connection. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example 1

[0024] Please see the appendix Figures 1-5 This utility model discloses a detachable tapered cement flange rod, including a cement rod body 1 and a pre-embedded foundation base 4, as well as an upper flange 2 and a lower flange 3, wherein:

[0025] The cement pole 1 is a tapered pole, and the upper flange 2 is fixed to the bottom of the cement pole 1;

[0026] The lower flange 3 is fixed to the upper end of the pre-embedded foundation 4;

[0027] Both the upper flange 2 and the lower flange 3 include a fixed base 21. The fixed base 21 is equipped with a flange 22. The flange 22 has multiple snap-fit ​​grooves 25 on its surface. The flanges 22 on the upper flange 2 and the lower flange 3 are detachably connected by connecting bolts 23. An insert gasket 24 is also inserted into the snap-fit ​​groove 25.

[0028] Furthermore, the snap-fit ​​groove 25 is a fan-shaped groove, and multiple snap-fit ​​grooves 25 are arranged in a ring and are equally spaced on the surface of the flange 22. The protruding part of the flange 22 and the corner of the bottom surface of the snap-fit ​​groove 25 are all rounded. The flanges 22 on the upper flange 2 and the lower flange 3 are joined together by the snap-fit ​​groove 25.

[0029] Specifically, after the flanges 22 on the upper flange 2 and the lower flange 3 are aligned, the protrusions on the different flanges 22 will insert into the snap-fit ​​groove 25 of the other flange 22, making it impossible to choose which flange 22 to snap together. This makes it easy for construction personnel to stabilize their position and allows for convenient diagonal tightening of the connecting bolts 23.

[0030] Furthermore, multiple reinforcing steel plates 27 are installed between the fixed base 21 and the flange 22. The flange 22 has a 15mm thick interlocking groove 25 and a 30mm thick protruding part.

[0031] Specifically, the above design not only improves the strength of the upper flange 2 and the lower flange 3, but also ensures that the setting of the interlocking groove 25 does not reduce the strength of the flange 22.

[0032] Furthermore, the pre-embedded foundation base 4 includes a base body 41, a fixed platform 42 is installed on the upper end of the base body 41, and a fixed base 21 on the lower flange 3 is installed on the upper end of the fixed platform 42. The base body 41 is hollow inside.

[0033] Specifically, when installing the hollow base, sufficient space can be reserved to allow enough concrete to be poured in to fix the pre-embedded base 4.

[0034] Furthermore, a connecting steel plate 12 is fixed to the bottom of the cement pole 1, and the connecting steel plate 12 is fixedly connected to the reinforcing cage 11 inside the cement pole 1. The fixing base 21 on the upper flange 2 is welded to the bottom of the connecting steel plate 12.

[0035] Specifically, compared to directly welding the fixed base 21 to the bottom of the cement pole 1, this design can improve the welding quality and strength, and avoid poor welding quality affecting the flange's load-bearing capacity. Example 2

[0036] Based on the above embodiment 1, this embodiment provides a leveling structure for flange connection. The bottom surface of the snap-fit ​​groove 25 and the outer surface of the protruding part of the flange 22 are both provided with gasket grooves 26. The inserted gasket 24 is movably inserted into the gasket groove 26 from the outside. The inserted gasket 24 is U-shaped and the front end is a claw-shaped inward bend.

[0037] In this embodiment, if there is unevenness or foreign objects between the flange 22 and the foundation, the contact surface will not be tight, which will affect the stability of the connection. When tightening the connecting bolts 23, gaps will be generated at the uneven areas. The connection can be adjusted by inserting the insert shim 24 into the uneven areas to prevent the connection from becoming loose.

[0038] The working principle and usage process of this utility model are as follows: With the lower flange 3 on the cement pole 1 facing downwards, the cement pole 1 is lifted and erected by mechanical equipment and moved to the upper end of the pre-embedded foundation 4, so that the flange 22 on the upper flange 2 and the lower flange 3 are aligned with each other. Then, the cement pole 1 is slowly lowered so that the flange 2 and the flange 22 on the upper flange 2 and the lower flange 3 are fastened with each other through the fastening groove 25. At this time, the connecting bolts 23 can be used to tighten the installation connecting bolts 23 gradually in a diagonal cross manner. If it is found that the two flanges 22 are not flat during the tightening process, insert the gasket 24 through the gasket groove 26 into the gap between the flanges 22 for support and adjustment.
