Description

Technical Field

[0001] This utility model belongs to the technical field of triangular truss beams for substations, specifically a hanging device for triangular truss beams in high-voltage substations. Background Technology

[0002] In high-voltage substations, triangular truss beams typically have long spans due to the layout and safety requirements of electrical equipment. These truss beams not only need to bear enormous loads, but also, depending on the different locations and angles of incoming and outgoing line hanging points, form various specifications of hanging structures. This diversity increases the complexity of drawing, fabrication, and installation processes, thereby extending the overall project duration and increasing construction costs.

[0003] For example, the Chinese utility model patent with authorization announcement date of November 11, 2022 and authorization announcement number CN21783039U discloses a new hanging point structure on the existing steel frame triangular truss beam of a substation, including an upper chord, a front lower chord, and a rear lower chord that make up the triangular truss. A front clamp is provided on the front lower chord, and a new hanging plate is fixedly connected to the front half of the front clamp. A front clamp rear connecting plate is fixedly connected to the rear half of the front clamp. A rear clamp is provided on the rear lower chord, and a rear clamp front connecting plate is provided on the front half of the rear clamp. An upper connecting rod and a lower connecting rod are respectively provided between the rear clamp front connecting plate and the front clamp rear connecting plate.

[0004] In the aforementioned prior art, additional hanging points are added to the triangular truss beam. However, these additional hanging points are located on the side of the main chord of the beam. If the hanging points are located between the nodes of the main chord of the beam, it cannot be guaranteed that the tension of the additional hanging points will be transferred to the nodes of the main chord of the beam. This results in unreasonable stress distribution and cannot guarantee the stability of the steel structure.

[0005] Therefore, how to effectively solve the above-mentioned shortcomings is an urgent technical problem to be solved. Utility Model Content

[0006] To address the shortcomings in the aforementioned background technology, this utility model proposes a hanging device for triangular truss beams in high-voltage substations, which solves the problem of unreasonable stress on newly added hanging points and the inability to guarantee the stability of the steel structure.

[0007] The technical solution of this application is as follows:

[0008] A wire-hanging device for a triangular truss beam in a high-voltage substation includes a first connector connected to the lower chord of the triangular truss beam. The first connector is detachably connected to an additional rod via a second connector. The additional rod is provided with a support for the conductor to pass through. The first connector is located at a node of the web member of the triangular truss beam. This invention incorporates additional rods at the nodes of the web members of a triangular truss beam via connectors one and two. These additional rods transfer the tension of the support members through which the conductor passes to the nodes of the lower chord of the triangular truss beam, resulting in more balanced stress and ensuring the overall stability of the beam. Considering the impact of temperature variations on conductor tension, conductor supports can be flexibly positioned at any location on the additional rods, enabling adjustable wire placement and standardized production. This simplifies the design process, improves processing and construction efficiency, reduces costs, and provides flexibility, contributing to the long-term stable operation of the system. Furthermore, this invention offers a modular design concept, allowing for the replacement of additional rods of different sizes to meet the needs of truss beams with varying spans, significantly improving the versatility and economy of the device. The additional rods and supports can be replaced multiple times as needed, and installation and disassembly do not directly contact the triangular truss beam, preventing damage.

[0009] Furthermore, at least two of the first and second connectors are provided to enhance the stability of the additional rod installation.

[0010] Furthermore, the first connector includes a first connecting plate connected to the lower chord, and the first connecting plate is provided with a hole for connecting to the second connector.

[0011] Furthermore, both ends of the connecting plate are provided with stiffening ribs.

[0012] Furthermore, the second connector includes a second connecting plate and a third connecting plate arranged in parallel. The second connecting plate is connected to the additional rod, and the second connecting plate is provided with a second hole for connecting with the third connecting plate.

[0013] Furthermore, connecting plates three are provided on both sides of the connecting plate two.

[0014] Furthermore, the connecting plate three is provided with a plurality of holes three, which are respectively connected to holes one and two by bolt groups.

[0015] Furthermore, stiffening ribs are provided at both ends of the connecting plate two.

[0016] Furthermore, the support member includes a connecting plate four connected to the additional rod, and the connecting plate four is provided with a hole four for the wire to pass through.

[0017] Furthermore, the triangular truss beam has two parallel lower chord members.

[0018] The specific beneficial effects of this utility model include:

[0019] 1. In this utility model, additional rods are set at the nodes of the web members of the triangular truss beam through connector one and connector two, so as to transfer the tension of the support member through which the conductor passes to the node of the lower chord of the triangular truss beam, making the force more balanced and ensuring the overall stability of the triangular truss beam.

[0020] 2. Considering the influence of factors such as temperature changes on conductor tension, conductor support components can be flexibly set at any position on the additional rod as needed, thereby achieving adjustability of the hanging position and standardized production. This not only simplifies the design process but also improves processing and construction efficiency, reduces costs, and is flexible in use, which helps maintain the long-term stable operation of the system.

[0021] 3. This utility model provides a modular design concept, which can meet the needs of truss beams with different spans by replacing additional rods of different sizes, greatly improving the versatility and economy of the device;

[0022] 4. The additional rods and support components of this utility model can be replaced multiple times as needed. They do not directly contact the triangular truss beam during installation and disassembly, and will not cause damage to the triangular truss beam.

[0023] 5. Through the combined design of the additional pole and conductor support, this device is not only suitable for new projects, but also for the renovation and upgrading of existing substations. Attached Figure Description
