Description

Technical Field

[0001] This utility model belongs to the field of power tower technology, specifically relating to a lattice-type tower lightning protection wire ring hanging point. Background Technology

[0002] Currently, traditional lightning protection wire hanging points for lattice towers generally use angle steel or polygonal plate structures, with multiple independent hanging plates set according to the number and direction of the wires. In existing technology, due to the structural form of the lattice tower, the hanging points are usually arranged on the main or auxiliary members of the lattice column, resulting in limited wire hanging direction. Furthermore, because the direction and number of wires vary in different projects, the hanging point form needs to be designed individually according to the actual project, leading to diverse hanging plate forms, difficulty in standardization, complex nodes, and poor versatility. Moreover, multiple points result in complex node structures, uneven stress distribution, and a tendency for stress concentration, affecting overall stability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ring-shaped hanging point for lightning protection wires of a lattice tower, which solves the problems of diverse forms and poor versatility of existing hanging wire structures, and realizes the ability to hang wires in various directions to cope with various situations where there are many hanging points and the hanging wires are scattered, and improves the overall performance of the top of the lattice column.

[0004] According to the technical solution of this utility model, this utility model provides a ring-shaped hanging point for lightning protection wires of a lattice tower, including a ring-shaped hanging plate, a central hole in the middle of the ring-shaped hanging plate, and multiple hanging holes distributed circumferentially around the periphery of the ring-shaped hanging plate; the ring-shaped hanging plate is set on the top of the lattice tower, and the hanging holes are all located outside the cross-sectional area of ​​the lattice tower.

[0005] In some implementations, the annular hanging plate is a one-piece molded circular steel plate.

[0006] In some embodiments, the annular hanging plate is fixedly connected to the top of the lattice tower by bolts or welding, and the fixed connection position between the annular hanging plate and the top of the lattice tower is located between the central hole and the hanging hole.

[0007] In some embodiments, the hanging holes are evenly distributed circumferentially along the edge of the annular hanging plate.

[0008] In some embodiments, the lattice tower includes multiple connected lattice column main members and multiple lattice column auxiliary members. The cross-sectional shape of the lattice tower is polygonal, and the position of the lattice column main members corresponds to the vertex of the polygon. The lattice column auxiliary members are located between the lattice column main members.

[0009] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This utility model discloses a lattice-type tower lightning protection wire ring hanging point. By adopting an integral ring hanging plate structure and rationally arranging the hanging holes, it can flexibly adapt to different directions and quantities of hanging wires, greatly improving the versatility, adaptability, and flexibility of the hanging point arrangement, and effectively solving the problem of limited hanging direction. The evenly distributed hanging holes along the edge of the ring plate can accommodate wire connections in various directions, significantly improving the versatility of the hanging point. The hanging plate and lattice column are preferably fixed using high-strength bolts or welding, enhancing the integrity of the node and the stability of the structure, avoiding uneven stress and stress concentration caused by multiple points of arrangement, thereby improving the overall load-bearing capacity and safety performance of the tower. Furthermore, the ring plate structure with a central hole, compared to ordinary plate structures without a central hole, reduces the total material usage while ensuring the strength and stability of the hanging plate.

[0013] This utility model provides a ring-shaped hanging point for lightning protection wires of a lattice tower, which solves the problems of diverse hanging structure forms and poor versatility of existing hanging structures. The main concept and feature is the use of a ring-shaped hanging plate and a structure with hanging holes arranged around it, which can realize the hanging of wires in various directions to cope with various situations with many hanging points and dispersed hanging directions, and improve the overall performance of the top of the lattice column.

[0014] Please see Figure 1 , Figure 2This utility model discloses a ring-shaped lightning protection wire hanging point for a lattice tower, comprising a ring-shaped hanging plate 1 with a central hole 2 in the middle. Multiple hanging holes 3 are distributed circumferentially around the ring-shaped hanging plate 1. The use of a ring-shaped hanging plate simultaneously achieves material saving, weight reduction, and ensures structural strength. The ring-shaped hanging plate 1 is located at the top of the lattice tower, and the hanging holes 3 are all located outside the cross-sectional area of ​​the lattice tower. This ensures that the structure of the lattice tower does not obstruct the hanging holes 3, and each side of the lattice tower has multiple usable hanging holes. Naturally, the diameter of the hanging holes 3 matches the lightning protection wire connector, and the position of the hanging holes can be flexibly selected according to the actual hanging direction. This solution not only simplifies the node structure and improves versatility but also significantly enhances the load-bearing capacity and adaptability of the hanging point, suitable for various directions and quantities of lightning protection wire installation requirements.

[0015] Preferably, the annular hanging plate 1 is a one-piece molded circular steel plate, more specifically, for example, it is obtained by hollowing out a central hole in the middle of a circular steel plate. More specifically, the diameter of the annular hanging plate 1 is determined according to the actual engineering requirements, and the thickness should meet the structural bearing capacity and stability requirements.

[0016] Preferably, the annular hanging plate 1 is fixedly connected to the top of the lattice tower by bolts (high-strength bolts) or welding to ensure the integrity and reliability of the node. The fixed connection position between the annular hanging plate 1 and the top of the lattice tower is located between the central hole 2 and the hanging hole 3, allowing for sufficient space for fixing, and the fixing position is not adjacent to the edge of the annular hanging plate 1 to ensure structural strength.

[0017] Preferably, the hanging holes 3 are evenly distributed along the circumferential edge of the annular hanging plate 1. While ensuring structural strength, the number of hanging holes 3 can be as large as possible, and the spacing between the hanging holes 3 is equal, so as to make it more versatile and the stress can be more uniform during application.

[0018] Please also refer to Figure 2 The lattice tower includes multiple connected lattice column main members 4 and multiple lattice column auxiliary members 5. The cross-sectional shape of the lattice tower is polygonal, and the position of the lattice column main members 4 corresponds to the vertex of the polygon. The lattice column auxiliary members 5 are located between the lattice column main members 4. The lattice column auxiliary members 5 connect adjacent or diagonally positioned lattice column main members 4 horizontally or obliquely to form a stable power tower structure. However, this also presents the problem of complex and diverse wiring point settings. Therefore, this type of power tower is particularly suitable for adopting the solution of this utility model.

[0019] For example Figure 1In the embodiment shown, the cross-sectional shape of the lattice tower is square, and the geometric center of the square coincides with the geometric center of the annular hanging plate 1. The size and position of the central hole 2 are such that it is located inside the square. The main lattice column 4 is located at the four corners of the square and naturally has a sufficiently large gap between it and the edge of the central hole 2, so that it can be conveniently and stably screwed or welded for fixing. The hanging hole 3 is further located on the outside of the square. While ensuring structural strength, the hanging hole 3 is close enough to the edge contour of the annular hanging plate 1 to further save material and reduce weight.

[0020] In summary, a typical embodiment of this utility model involves setting a single annular plate at the top of the lattice column. The annular plate is fixed to the lattice column using high-strength bolts or welding, ensuring the integrity and stability of the structure. Multiple hanging holes are evenly arranged along the edge of the annular plate, allowing the hanging plate to connect wires from any direction. Compared with the prior art, this utility model has the following beneficial technical effects.

[0021] 1. A ring-shaped steel plate is set on the top of the lattice column as a hanging plate, which breaks through the constraints of the traditional hanging point layout which is limited by the position of the main or auxiliary materials of the lattice column, making the hanging direction more free and flexible.

[0022] 2. The hanging holes are evenly arranged along the edge of the ring steel plate, which can be flexibly selected according to the actual hanging direction, avoiding the limitation of traditional hanging point forms that require separate design due to project differences, and greatly improving versatility.

[0023] 3. The ring-shaped hanging plate is fixed to the lattice column with high-strength bolts or welding, which enhances the integrity and structural stability of the node.

[0024] 4. The ring plate has an opening in the center of the circular plate. While ensuring strength, it reduces the amount of material used and the weight, while maintaining the stability and load-bearing capacity of the structure. This design not only improves the efficiency of material utilization, but also reduces the manufacturing cost.
