Description

Technical Field

[0001] This invention relates to the field of transmission tower reinforcement technology, and in particular to a transmission tower and its reinforcement device. Background Technology

[0002] The power system is a vital component of a city's lifeline system, and its safety is crucial to national security, social stability, and many other issues; it is the lifeline of national security and the economy. Therefore, disaster prevention and mitigation for the power system must be given sufficient attention. Transmission lines play a vital role in the entire power system, responsible for transmitting and distributing electricity. Therefore, the maintenance and disaster prevention of transmission lines must also be given sufficient importance and attention.

[0003] For power transmission lines, extreme weather such as strong winds, rain, and snow have a significant impact, leading to frequent wind-induced tower collapses. One important reason is that the wind resistance capacity of transmission towers is lower than that required to withstand strong winds. Furthermore, in wind-induced tower collapses, the upper section of the tower legs is most vulnerable to damage, resulting in the collapse of the entire tower, primarily due to the instability of the diagonal members in this section.

[0004] Currently, in the design of existing transmission towers, the connection between the diagonal angle steel and the main angle steel is mainly through single-sided connection. However, the buckling load-bearing capacity of angle steel connected on one side is reduced, thus decreasing the wind resistance of the transmission tower. A single-sided connection of angle steel is a method of connecting two angle steels, where one side of one angle steel is connected to one side of the other angle steel by bolts, welding, or other fixing methods, while the other side of the other angle steel remains free. This connection method is commonly used in the construction of frames, supports, beams, columns, and other structural elements to achieve the required support, bracket, or frame structure. Although applicable building standards and safety codes must be ensured when designing and using single-sided connections, single-sided connected angle steel has the following disadvantages: 1. Poor structural stability: Single-sided connected angle steel may be relatively unstable under lateral forces or torques because only one side is connected, while the other side is free and suspended. This may lead to structural deformation or instability, especially under complex load conditions; 2. Limited load-bearing capacity: Single-sided connections generally have lower load-bearing capacity because the connection is only on one side. This may limit the load-bearing capacity of the structure, especially in applications that require supporting large loads; 3. Not suitable for long-span structures: For long-span structures, such as bridges or large buildings, single-sided connections are usually not the most suitable option, as they may not provide sufficient structural stability and load-bearing capacity. Summary of the Invention

[0005] The purpose of this invention is to propose a transmission tower and its reinforcement device to solve the problem that the load-bearing capacity of the transmission tower is reduced due to the single-sided connection between the inclined angle steel and the main angle steel. The reinforcement device can improve the load-bearing capacity of the transmission tower, thereby enhancing its wind resistance.

[0006] To achieve the above objectives, the present invention provides a reinforcement device for transmission towers, comprising a reinforcement component, a support component, and an adjustment component. The reinforcement component includes a first plate and a second plate perpendicular to the first plate for reinforcing the inclined angle steel of the transmission tower, the first plate and the second plate being interconnected. The support component includes a third plate and a fourth plate disposed on one side of the third plate for connecting the main angle steel of the transmission tower, one end of the fourth plate being hinged to the second plate. One end of the adjustment component is connected to the first plate and the other end is connected to the third plate, the adjustment component being used to adjust the opening between the reinforcement component and the support component.

[0007] Furthermore, the reinforcement component includes two parallel first plates and two parallel second plates, with the two first plates disposed between the two second plates; a slot for insertion into the inclined angle steel is provided between the two first plates, and one end of the slot has an opening and the other end is provided with a limiting plate.

[0008] Furthermore, the adjustment assembly includes a guide rail and a guide rod slidably connected to the guide rail. The guide rail has a sliding cavity inside, one end of which is connected to the third plate, and the other end has an opening communicating with the sliding cavity. One end of the guide rod is inserted into the sliding cavity through the opening, and the other end is connected to the first plate.

[0009] Furthermore, the guide rail is provided with a locking mechanism to prevent the guide rod from falling out of the sliding cavity.

[0010] Furthermore, at least two adjustment components are provided.

[0011] Furthermore, both the second plate and the fourth plate are provided with bolt holes for connecting the transmission tower.

[0012] Optionally, the second plate and the fourth plate are welded or snapped to the transmission tower.

[0013] Another aspect of the present invention provides a transmission tower comprising a tower body and the aforementioned reinforcement device for the transmission tower.

[0014] Furthermore, the tower body includes main angle steel and diagonal angle steel for connecting the main angle steel. Support plates are provided on the inner and outer sides of the spine of the main angle steel. The first plate is inserted into one side of the main angle steel. The second plate is fixedly connected to one side of the diagonal angle steel. The fourth plate is arranged parallel to one side of the support plate and is fixedly connected to the support plate.

[0015] Optionally, at least two of the aforementioned reinforcement devices for the transmission tower are provided, and the reinforcement devices for the transmission tower are respectively provided on the two legs of the main material angle steel.

[0016] Compared with the prior art, the advantages of the transmission tower and its reinforcement device according to the present invention are as follows:

[0017] By setting up reinforcement components, support components, and adjustment components, and through the cooperation of the first and second plates on the reinforcement components, the diagonal angle steel connecting the main angle steel of the transmission tower is reinforced, making the connection between the diagonal angle steel and the main angle steel tighter. This solves the problem of reduced load-bearing capacity of the diagonal angle steel in the transmission tower due to unilateral connection, thereby improving the wind resistance of the transmission tower. By setting up support components, the reinforcement device for the transmission tower can be firmly fixed to the main angle steel of the transmission tower body. By setting up adjustment components, the opening between the reinforcement components and support components can be adjusted, making the reinforcement device for the transmission tower applicable to diagonal angle steel with different inclination angles, thus improving its applicability.
