Technical Field

[0001] This application relates to the technical field of angle steel connection for power transmission towers, and in particular to a wind-resistant angle steel connection device for power transmission towers with reinforcing ribs. Background Technology

[0002] Transmission towers are the support points for overhead lines. A single-circuit transmission tower has one circuit installed on it, while a double-circuit transmission tower has two circuits installed on it.

[0003] A search revealed Chinese Patent Publication No. CN202020932828.1, which discloses a connecting device suitable for angle steel of iron towers. The device includes a main plate, a secondary angle plate, a hanging point angle plate, hanging holes, and multiple bolts. The outer side of the main plate is connected to the hanging point angle plate, and the hanging point angle plate is provided with the hanging holes. Compared with the traditional method of drilling holes in the original main material of the tower, this reduces the difficulty of high-altitude operations, improves work efficiency, and avoids weakening the cross-section of the original main material of the tower, thus avoiding the occurrence of unsafe factors that may affect the stability of the existing iron tower and contributing to the safe and stable operation of transmission lines.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: although they can achieve the effects of connection and fixation, the fixing effect of a single bolt is not good, and multiple bolts are exposed to the external environment, which will cause them to age rapidly due to the influence of external weather and environment, and they are prone to loosening later.

Two splicing parts are movably installed between two adjacent reinforcing ribs. Fixing parts are fixedly installed on the side of the two splicing parts that are far apart from each other. The fixing parts are fixedly connected to the outer wall of the angle plate one and the outer wall of the angle plate two.

[0007] Optionally, the reinforcing rib includes a rib body, which is arranged in an isosceles trapezoidal shape, and a connecting block is fixedly connected to the outer side of the rib body.

[0010] Optionally, the head of the bolt is provided with a tool groove, which is arranged in the shape of a regular pentagon.

[0011] Optionally, the inner cavity of the threaded groove is threaded with a threaded post, one side of which is in contact with the bolt head, and the other side of which extends to the outside of the threaded groove.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a wind-resistant angle steel connection device for power transmission towers with reinforcing ribs. For example... Figure 1 As shown, it includes a first corner plate 1, and a second corner plate 2 is provided in the inner cavity of the first corner plate 1. Both the first corner plate 1 and the second corner plate 2 are arranged in an "L" shape. Reinforcing ribs 3 are fixedly installed on the inner wall of the first corner plate 1 and the outer wall of the second corner plate 2. The reinforcing rib 3 includes a rib body 301, which is arranged in an isosceles trapezoidal shape. A connecting block 302 is fixedly connected to the outer side of the rib body 301. Two connecting blocks 302 on the same side are fixedly connected to the inner wall of the first corner plate 1 and the outer wall of the second corner plate 2, respectively. The reinforcing rib 3 is formed by the rib body 301 and the connecting block 302, which can improve the connection strength during subsequent connection.

[0023] Please see Figure 5 Two splicing components 4 are movably installed between two adjacent reinforcing ribs 3. The splicing component 4 includes a splicing plate 401. Splicing grooves 402 are provided on both sides of the outer wall of the splicing plate 401. The splicing grooves 402 are slidably connected to the outer wall of the corresponding rib 301. By sliding the rib 301 into the splicing groove 402 and the rib 301 and the splicing groove 402 are tightly fitted, the two adjacent reinforcing ribs 3 can be tightly connected together, thereby making the angle plate 1 and the angle plate 2 tightly connected together, which is used for the subsequent connection of the angle steel of the wind-resistant power tower.

[0024] Please see Figure 5The splicing component 4 is used to connect the two reinforcing ribs 3, thereby connecting the angle plate 1 and the angle plate 2. This allows the angle plate 1 and the angle plate 2 to connect the angle steel of the two wind-resistant power towers. Fixing components 5 are fixedly installed on the opposite sides of the two splicing components 4. Each fixing component 5 includes a side block 501, which is fixedly connected to the outer wall of the splicing plate 401. The side block 501 has a threaded groove 502, and a round hole 503 is formed on the inner wall of the threaded groove 502. Several fixing holes 506 are formed on the outer walls of both the angle plate 1 and the angle plate 2. The inner cavity of the threaded groove 502 is provided with… Bolt 504, one end of bolt 504 passes through round hole 503 and is threaded into the inner cavity of corresponding fixing hole 506. By passing bolt 504 through round hole 503 and threaded into fixing hole 506 on corner plate 1 and corner plate 2, the side block 501 is fixed to corner plate 1 and corner plate 2, thereby fixing the splice 4. The head of bolt 504 is provided with tool groove 505. Tool groove 505 is set in the shape of a regular pentagon. With the setting of tool groove 505, a targeted regular pentagon tool can be embedded in tool groove 505 to avoid damage caused by human error.

[0025] Please see Figure 5 The threaded groove 502 has a threaded post 507 threadedly connected to its inner cavity. One side of the threaded post 507 is in contact with the head of the bolt 504, and the other side of the threaded post 507 extends to the outside of the threaded groove 502. By threading the threaded post 507 into the threaded groove 502, the threaded groove 502 is sealed, and the bolt 504 is hidden, preventing the bolt 504 from being exposed to the external environment, aging, and loosening of the device. Several anti-slip grooves 508 are provided on the side of the threaded post 507 away from the bolt 504. The multiple anti-slip grooves 508 make it easy for workers to apply force during installation and disassembly. The fastener 5 is fixedly connected to the outer wall of corner plate 1 and corner plate 2, and the fastener 5 is used to fix the splicing part 4 to corner plate 1 and corner plate 2.

[0026] The implementation principle of the wind-resistant power tower angle steel connection device with reinforcing ribs in this application embodiment is as follows: First, angle plate 1 and angle plate 2 are attached to the outer wall of the wind-resistant power tower angle steel to be connected. Then, the splicing groove 402 on the splicing piece 4 is aligned with the ribs 301 on angle plate 1 and angle plate 2, and the ribs 301 are embedded in the splicing groove 402. By connecting the ribs 301 with the splicing plate 401, the splicing of angle plate 1 and angle plate 2 is realized. At this time, angle plate 1 and angle plate 2 abut against the outer wall of the wind-resistant power tower angle steel to be connected. Then, the bolt 504 on the side block 501 is threaded into the fixing hole 506, and the threaded post 507 is threaded into the threaded groove 502. While achieving fixation, the bolt 504 is hidden to prevent the bolt 504 and other components from being affected by the external environment and becoming loose.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
