Description

Technical Field

[0001] This utility model relates to the field of pole connection, specifically a ring-shaped concrete pole connection device. Background Technology

[0002] In power systems, concrete poles are widely used in the construction of transmission and distribution lines due to their structural stability and durability. As the requirements for safety and reliability of power systems continue to increase, the connection requirements for concrete poles are also becoming increasingly stringent.

[0003] In the prior art, the connection between two poles is usually made by two built-in flanges. The built-in flanges are firmly connected to the main reinforcement inside the pole by high-strength bolts to form a stable overall structure, which significantly improves the connection strength between the poles.

[0004] However, when the built-in flange is connected by bolts, it may be affected by factors such as the swaying of the utility pole. Over time, the nuts on the bolts may loosen, causing the connection to be unstable. In addition, the bolt structure used for connection is exposed to the outside and is very susceptible to corrosion, which leads to a decrease in the strength of the bolt connection. Utility Model Content

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1 to 8 This utility model provides a technical solution: a ring-shaped concrete pole connection device;

[0029] Example 1:

[0030] To prevent loosening when bolt 6 is connected to the internal flange, the upper internal flange 3 and the lower internal flange 4 are connected by an anti-loosening component. This component includes: bolt 6, with a nut 8 threaded onto the outer surface of the bolt 6; a first wedge groove 7 and a second wedge groove 9 respectively formed on the inner walls of bolt 6 and nut 8; a wedge block 11 embedded on the inner surface of the first and second wedge grooves 7 and 9; the first and second wedge grooves 7 and 9 being corresponding wedge-shaped bevels; and the wedge block 11 being inserted into the first and second wedge grooves 7 and 9. A spring washer 10 is provided on the lower surface of the nut 8, and the lower surface of the spring washer 10 has a serrated structure. The inner walls of bolt 6 and nut 8 are respectively provided with a first wedge groove 7 and a second wedge groove 9. When nut 8 is tightened, the first wedge groove 7 and the second wedge groove 9 coincide. By inserting a wedge block 11 into the inner surface of the first wedge groove 7 and the second wedge groove 9, the wedge block 11 restricts the rotation of nut 8 on bolt 6, thereby preventing bolt 6 from loosening when connected to the inner flange and strengthening the connection strength of bolt 6. The lower surface of spring washer 10 has a serrated structure. When nut 8 is tightened, nut 8 applies a downward force to spring washer 10, which makes the serrated structure firmly lock onto the surface of inner flange, increasing the contact area and further preventing bolt 6 from loosening.

[0031] Example 2:

[0032] Based on Embodiment 1, to protect the anti-loosening components and prevent corrosion, mounting grooves 5 are provided on the outer walls of the upper inner flange 3 and the lower inner flange 4. Protective components are installed through the mounting grooves 5, including a first protective plate 12 and a second protective plate 13. Mounting blocks 14 are provided on the inner walls of the first and second protective plates 12 and 13. Connecting plates 15 are fixedly installed on the side surfaces of the first and second protective plates 12 and 13. Connecting grooves 16 are provided on the inner walls of the connecting plates 15, and connecting plates 17 are slidably inserted into the inner surface of the connecting grooves 16. The first and second protective plates 12 and 13 are connected to the mounting grooves 5 on the outer walls of the upper and lower inner flanges 3 and 4 via the mounting blocks 14. The first protective plate 12 and the second protective plate 13 are arc-shaped, corresponding to the outer surfaces of the upper built-in flange 3 and the lower built-in flange 4. The inner surface of the connecting plate 17 is threaded with screws 18, which limit the sliding of the connecting plate 17 on the inner surface of the connecting groove 16. The mounting blocks 14 on the inner walls of the first protective plate 12 and the second protective plate 13 are inserted into the mounting grooves 5 in the built-in flanges to guide the installation. The connecting plate 17 is slidably inserted into the connecting grooves 16 on the inner wall of the connecting plate 15, thereby protecting the bolt 6 structure used for connection by the first protective plate 12 and the second protective plate 13, preventing the bolt 6 from being exposed to the outside and corroding, and improving the connection strength of the bolt 6.

[0033] Working principle: In actual use, to prevent loosening when the bolt 6 is connected to the internal flange, a first wedge groove 7 and a second wedge groove 9 are respectively provided on the inner walls of the bolt 6 and the nut 8. When the nut 8 is tightened, the first wedge groove 7 and the second wedge groove 9 coincide. By inserting a wedge block 11 into the inner surface of the first wedge groove 7 and the second wedge groove 9, the wedge block 11 restricts the rotation of the nut 8 on the bolt 6, thereby preventing the bolt 6 from loosening when connected to the internal flange and strengthening the connection strength of the bolt 6. The lower surface of the spring washer 10 has a serrated structure. When the nut 8 is tightened, the nut 8... The spring washer 10 applies a downward force, which in turn causes the serrated structure to firmly lock onto the surface of the built-in flange, increasing the contact area and further preventing the bolt 6 from loosening. Secondly, when protecting the anti-loosening component, corrosion is prevented. The mounting blocks 14 on the inner walls of the first protective plate 12 and the second protective plate 13 are inserted into the mounting grooves 5 inside the built-in flange, which serve as guides and facilitate installation. The connecting plate 17 is slidably inserted into the connecting grooves 16 on the inner wall of the connecting plate 15, thereby protecting the bolt 6 structure used for connection with the first protective plate 12 and the second protective plate 13, preventing the bolt 6 from being exposed to the outside and corroding, and improving the connection strength of the bolt 6.

[0034] 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.
