Description

Technical Field

[0001] This utility model relates to the field of power equipment accessories technology, and in particular to an anti-loosening nut for power transmission towers. Background Technology

[0002] In power transmission networks, power towers serve as crucial supports for transmission lines, and their structural stability is paramount. The various components of the tower are typically secured together using nuts and other fasteners. However, due to their long-term exposure to the outdoor environment, power towers are subject to various factors such as strong winds, vibrations, and temperature fluctuations. Under the combined effect of these factors, traditional nuts are highly prone to loosening.

[0003] The inventors believe that traditional nuts often suffer from the following drawbacks: Because power transmission towers are exposed to the outdoor environment for extended periods, they are subject to various factors such as strong winds, vibrations, and temperature changes. Under the combined effect of these factors, traditional nuts are prone to loosening. When the nut itself loosens, the overall stress distribution on the tower changes, leading to excessive localized stress, structural deformation, and potentially causing the tower to tilt or even collapse, threatening the lives of nearby personnel. Therefore, this invention proposes an anti-loosening nut for power transmission towers to address these issues. Summary of the Invention

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the loosening of the nut body, which changes the overall force distribution of the tower, leading to excessive local stress on the power tower, causing structural deformation, and causing the tower to tilt or even collapse. Therefore, this utility model proposes an anti-loosening nut for power towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power tower anti-loosening nut, comprising a nut body, a fixing frame slidably connected to the surface of the nut body, a connecting rod slidably connected to the inner surface of the fixing frame, a threaded plate fixedly connected to the arc surface of the connecting rod, two L-shaped plates fixedly connected to the arc surface of the connecting rod, a threaded rod inserted into the inner thread of the L-shaped plate, the arc surface of the threaded rod being threadedly connected to the fixing frame, the arc surface of the threaded rod being threadedly connected to the connecting rod, and two round holes opened on both sides of the fixing frame.

[0006] The aforementioned components achieve the following effects: they prevent the nut body from rotating, thus avoiding loosening of the nut body, changes in the overall stress distribution of the tower, excessive local stress on the power tower, structural deformation, tower tilting or even collapse, and threats to the safety of surrounding personnel, thereby improving the practicality of the device.

[0007] Preferably, a retaining ring is fixedly connected to the arc surface of the threaded rod, and the surface of the retaining ring is in contact with the fixing frame.

[0008] The aforementioned components achieve the following effect: preventing the threaded rod from pulling out, thus avoiding the situation where the threaded rod detaches from the L-shaped plate due to excessive rotation when the operator rotates the threaded rod, requiring secondary installation and increasing the operator's workload.

[0009] Preferably, a spring is fixedly connected to the inner surface of the fixing frame, and one end of the spring is fixedly connected to the connecting rod.

[0010] The effect achieved by the above components is to improve the stability of the connecting rod when it is not in use, and to prevent the connecting rod from shaking due to external force when the operator rotates the nut body, which would cause the connecting rod to continuously collide with the inner surface of the fixing frame and be damaged.

[0011] Preferably, the surface of the threaded plate is fixedly connected with several anti-slip blocks, and the size of the circular hole of the fixing frame is adapted to the size of the threaded rod.

[0012] The effect achieved by the above components is to increase the friction between the threaded plate and the surface of the external object, making the connection between the threaded plate and the external object more stable and further enhancing the anti-loosening effect.

[0013] Preferably, two connecting plates are fixedly connected to both sides of the fixing frame, eight fixing rods are fixedly connected to the surface of the nut body, a single-hole plate is rotatably connected to the arc surface of the fixing rod, a bolt is inserted into the internal thread of the single-hole plate, and the arc surface of the bolt is threadedly connected to the connecting plate.

[0014] The aforementioned components achieve the following effects: they facilitate the replacement of the mounting bracket, prevent the bracket from becoming damaged and difficult to replace after long-term use, reduce maintenance costs, and improve maintenance efficiency.

[0015] Preferably, a torsion spring is fitted onto the arc surface of the fixing rod, and the two ends of the torsion spring are fixedly connected to the fixing rod and the single-hole plate, respectively.

[0016] The aforementioned components achieve the following effects: they automatically open the single-hole plate while keeping it in the open position, facilitating further operation by staff, simplifying the process of replacing the mounting bracket, and improving work efficiency.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] This invention achieves the effect of preventing the nut body from rotating, avoiding the nut body from loosening, which would change the overall force distribution of the tower, causing excessive local stress on the power tower, leading to structural deformation, tower tilting or even collapse, and threatening the lives of people in the surrounding area. This improves the practicality of the device. Attached Figure Description

[0026] Reference Figure 1-6As shown, this utility model provides a technical solution: an anti-loosening nut for power transmission towers, comprising a nut body 1, a fixing frame 2 slidably connected to the surface of the nut body 1, a connecting rod 3 slidably connected to the inner surface of the fixing frame 2, a threaded plate 4 fixedly connected to the arc surface of the connecting rod 3, two L-shaped plates 5 fixedly connected to the arc surface of the connecting rod 3, and threaded rods 6 threadedly inserted into the L-shaped plates 5. The arc surface of the threaded rods 6 is threadedly connected to the fixing frame 2, and the arc surface of the threaded rods 6 is threadedly connected to the connecting rod 3. Two round holes are provided on both sides of the fixing frame 2, achieving the effect of preventing the nut body 1 from rotating, avoiding loosening of the nut body 1, changing the overall stress distribution of the tower, causing excessive local stress on the power transmission tower, leading to structural deformation, causing the tower to tilt or even collapse, threatening the surrounding area. To address the safety concerns of personnel, the device's practicality has been improved. A retaining ring 8 is fixedly connected to the arc surface of the threaded rod 6. The surface of the retaining ring 8 is in contact with the fixing frame 2. When the operator needs to use the threaded plate 4, they first rotate the threaded rod 6, causing the retaining ring 8 to rotate within the circular hole of the fixing frame 2 until the surface of the retaining ring 8 is in contact with the L-shaped plate 5. At this point, the arc surface of the threaded rod 6 completely separates from the fixing frame 2, preventing the threaded rod 6 from being pulled off. This avoids the situation where the threaded rod 6 detaches from the L-shaped plate 5 due to excessive rotation, requiring secondary installation and increasing the operator's workload. A spring 7 is fixedly connected to the inner surface of the fixing frame 2. One end of the spring 7... Fixedly connected to the connecting rod 3, when the worker needs to use the nut body 1, the spring 7 is in a stretched state. First, the worker releases the limiting force on the connecting rod 3, and the rebound force of the spring 7 causes the connecting rod 3 to slide on the inner surface of the fixing frame 2 until the connecting rod 3 is in a stable state. This achieves the effect of improving the stability of the connecting rod 3 when not in use, and avoids the situation where the connecting rod 3 shakes due to external force when the worker rotates the nut body 1, causing the connecting rod 3 to continuously collide with the inner surface of the fixing frame 2 and be damaged. Several anti-slip blocks 14 are fixedly connected to the surface of the threaded plate 4. The size of the round hole of the fixing frame 2 is adapted to the size of the threaded rod 6. When the worker needs to use the threaded plate 4, the worker first pulls to release the limiting force on the connecting rod 3. The connecting rod 3 is limited, and then the operator can push the connecting rod 3 to drive the threaded plate 4 to slide on the inner surface of the fixing frame 2. The threaded plate 4 drives the anti-slip block 14 to move until the surface of the threaded plate 4 is in contact with the surface of the external object. At this time, the anti-slip block 14 is in a compressed state, which increases the friction between the threaded plate 4 and the surface of the external object, making the connection between the threaded plate 4 and the external object more stable and further enhancing the anti-loosening effect. Two connecting plates 9 are fixedly connected to both sides of the fixing frame 2. Eight fixing rods 10 are fixedly connected to the surface of the nut body 1. The arc surface of the fixing rod 10 is rotatably connected to a single-hole plate 11. A bolt 12 is inserted into the thread of the single-hole plate 11. The arc surface of the bolt 12 is threadedly connected to the connecting plate 9. When the operator needs to replace the fixing frame 2,First, the operator rotates bolt 12 within the single-hole plate 11 until the arc surface of bolt 12 separates from the connecting plate 9. Then, the operator can rotate the single-hole plate 11 until it no longer hinders the movement of the connecting plate 9. At this point, the operator can pull the fixing bracket 2 to move the connecting rod 3 until the fixing bracket 2 separates from the nut body 1. Then, the operator can replace the fixing bracket 2 with a new one. This facilitates the replacement of the fixing bracket 2, avoiding the situation where the fixing bracket 2 becomes damaged and difficult to replace after long-term use, reducing maintenance costs and improving maintenance efficiency. A torsion spring 13 is fitted onto the arc surface of the fixing rod 10. The two ends of the torsion spring 13 are fixedly connected to the fixing rod 10 and the single-hole plate 11, respectively. When the worker needs to replace the fixing frame 2, they first release the limiting position on the connecting plate 9. At this time, the torque of the torsion spring 13 drives the single-hole plate 11 to rotate on the arc surface of the fixing rod 10 until the single-hole plate 11 no longer affects the movement of the connecting plate 9, thus achieving the effect of automatically opening the single-hole plate 11. Simultaneously, the single-hole plate 11 is kept in the open state, facilitating further operation by the worker, simplifying the process of replacing the fixing frame 2, and improving work efficiency.

[0027] Working principle: When the operator needs to use the threaded plate 4, the threads of the threaded plate 4 are in the opposite direction to the threads of the external connecting object. First, the operator rotates the threaded rod 6, causing the blocking ring 8 to rotate within the circular hole of the fixing frame 2 until the surface of the blocking ring 8 is in contact with the L-shaped plate 5. At this time, the arc surface of the threaded rod 6 is completely separated from the fixing frame 2. Then, the operator can push the connecting rod 3 to cause the threaded plate 4 to slide on the inner surface of the fixing frame 2. The threaded plate 4 causes the anti-slip block 14 to move until the surface of the threaded plate 4 is in contact with the surface of the external connecting object. At this time, the anti-slip block 14 is in a compressed state. When the operator needs to use the nut body 1, the spring 7 is in a stretched state. First, the operator releases the limit on the connecting rod 3, and the rebound force of the spring 7 causes the connecting rod 3 to move within the fixing frame 2. The inner surface slides until the connecting rod 3 is in a stable state. When the staff needs to replace the fixing frame 2, the staff first rotates the bolt 12 in the single hole plate 11 until the arc surface of the bolt 12 separates from the connecting plate 9. At this time, the torque of the torsion spring 13 drives the single hole plate 11 to rotate in the arc surface of the fixing rod 10 until the single hole plate 11 does not affect the movement of the connecting plate 9. At this time, the staff can pull the fixing frame 2 to drive the connecting rod 3 to move until the fixing frame 2 separates from the nut body 1, which achieves the effect of preventing the nut body 1 from rotating, avoiding the nut from loosening, changing the overall force distribution of the tower, causing excessive local force on the power tower, causing structural deformation, causing the tower to tilt or even collapse, threatening the life safety of surrounding personnel, and improving the practicality of the device.
