Description

Technical Field

[0001] The invention belongs to the field of communication iron towers, and in particular relates to an iron tower rapid expansion bracket with high reliability. Background Art

[0002] With the rapid development of information technology, the communications industry is facing unprecedented challenges and opportunities. As an important part of the communications infrastructure, the stability and safety of the tower structure are directly related to the reliable operation of the communications network.

[0003] In recent years, with the rapid advancement of new-generation information technologies such as 5G and the Internet of Things, the coverage of communication networks has continued to expand, placing higher demands on the carrying capacity and efficiency of towers. Traditional tower structural design and construction standards can no longer meet existing needs, and there is an urgent need to improve the performance and capacity of towers through technological innovation and transformation and upgrading. The expansion of traditional towers requires the addition of a signal mounting bracket to the tower body, and then the functional module is hung on the mounting bracket. If a simple bracket end welding method is used to add an expansion bracket to a traditional tower, the structural strength of the extended end is difficult to guarantee, and the existing expansion bracket lacks mounting locations such as fixing slots. The added functional module needs to be fixed to the expansion bracket by means of clamps, etc., which not only complicates the expansion operation, but also makes the installation reliability difficult to guarantee. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the bearing capacity of traditional iron towers is insufficient, and the existing expansion bracket fixing methods are scarce, making it difficult to meet the needs of safe, reliable and rapid expansion. A high-reliability iron tower rapid expansion bracket is provided, which adopts a two-piece spliced ​​expansion bracket and can perform clamp-type expansion at any tower size position. The expansion bracket is evenly spaced with installation slots to provide effective fixation and support for functional modules. At the same time, the installation slots serve as an elastic seam structure to ensure that the middle part of the expansion bracket can be opened to any size.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a high-reliability iron tower rapid expansion bracket, comprising a tower body, an antenna fixed around the top of the tower body, and an expansion bracket fixed to the tower body, the expansion bracket comprising a first bracket plate and a second bracket plate fixed back to back, the first bracket plate and the second bracket plate are both groove-shaped with a single-side opening, the groove bottom plates of the first bracket plate and the second bracket plate are vertically arranged and aligned with each other and have fixing holes, the upper groove walls and lower groove walls of the first bracket plate and the second bracket plate are evenly provided with elastic grooves, and each elastic groove divides the upper groove wall and the lower groove wall into a plurality of independent plates; the middle parts of the first bracket plate and the second bracket plate are respectively opened to the two outer sides in a circular sleeve on the tower body, the two ends of the first bracket plate and the second bracket plate extend outward in a straight line, the groove bottom plates are abutted against each other and are fixed by bolts at the fixing holes.

[0006] When the expansion bracket is used, two groove-shaped bracket plates are assembled back to back. Since the groove bottom plates of the first bracket plate and the second bracket plate are back to back, and the upper and lower groove walls are provided with elastic grooves, the middle part of the expansion bracket can be opened to both sides to form a circular hoop, which is fixed on the tower body, and the first bracket plate and the second bracket plate can be bolted at both ends. According to the different sizes of the tower body, the opening size of the middle part of the expansion bracket can be adjusted accordingly to adapt to the expansion of tower bodies of various sizes. The middle part of the expansion bracket can be welded to the tower body at the upper and lower sides, or it can be fixed to the tower body with fixing holes. Due to the elastic groove structure of the upper and lower groove walls, when the first bracket plate and the second bracket plate are opened to the outside respectively, the elastic groove opens to form a V-shape with a large outside and a small inside, and when the first bracket plate and the second bracket plate are bent to the same side, the outer ends of the elastic groove will abut against each other to prevent this bending trend and ensure the reliability of the fixation. The straight sections at both ends of the mounting bracket can provide mounting positions for the functional module, and the functional module can be supported by the outward-facing slots and elastic slots of the first bracket plate and the second bracket plate.

[0007] Preferably, the elastic groove is flush with the outer side of the groove bottom plate. The elastic groove completely penetrates to the roots of the upper groove wall and the lower groove wall, so that the middle part of the expansion bracket can be opened outward.

[0008] Preferably, a mounting hole is provided in the middle of several elastic grooves, and the mounting hole is formed by symmetrically opening semicircular grooves on the independent plates on both sides of the elastic groove. When the functional module is installed with the expansion bracket, the fixed part of the functional module can be clamped into the elastic groove with a sheet structure, or fixed with bolts and corresponding mounting holes.

[0009] Preferably, the outer end of the upper groove wall is provided with a folded edge downward, and the outer end of the lower groove wall is provided with a folded edge upward. The fixing part of the functional module can also be embedded in the card slots of the first bracket plate and the second bracket plate, buckled by the folded edge, and fixed with the mounting hole.

[0010] Preferably, the first bracket plate and the second bracket plate have an arc-shaped transition at the junction of the middle open section and the two end straight sections, and the independent plate of the upper groove wall is folded upward at the transition, and the independent plate of the lower groove wall is folded downward.

[0011] Preferably, the tower body fixed expansion bracket has a taper that is larger at the bottom and smaller at the top. The expansion bracket can be clamped on the conical surface of the tower body by its own weight to avoid sliding downward.

[0012] Preferably, the expansion brackets are arranged in pairs along the vertical direction of the tower body. The functional module can be fixed at two points on the two expansion brackets to ensure reliable fixation.

[0013] Preferably, a maintenance platform is provided below the expansion bracket.

[0014] The expansion bracket of the present invention can be flexibly adjusted to adapt to the expansion of different tower body sizes. The middle part of the expansion bracket itself is opened to form a hoop, and the two ends serve as support frames for functional components. The expansion bracket can be opened to both sides but cannot be bent to one side. It is flexible, reliable and easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 2 , 3As shown in Figures 4 and 5, the expansion bracket 3 includes a first bracket plate 5 and a second bracket plate 6 fixed back to back, and the first bracket plate 5 and the second bracket plate 6 are both groove-shaped with single-side openings, and the first bracket plate 5 and the second bracket plate 6 are provided with card slots facing outward. The groove bottom plates 13 of the first bracket plate 5 and the second bracket plate 6 are vertically arranged and aligned with each other and have fixing holes 10. The upper groove wall 11 and the lower groove wall 12 of the first bracket plate 5 and the second bracket plate 6 are evenly provided with elastic grooves 8, and each elastic groove 8 divides the upper groove wall and the lower groove wall into a plurality of independent plates 7. The depth of the elastic groove 8 is flush with the outer side of the groove bottom plate 13. A mounting hole 9 is provided in the middle of several of the elastic grooves 8, and the mounting hole 9 is formed by symmetrically opening semicircular grooves on the independent plates 7 on both sides of the elastic groove.

[0024] like Figure 2 As shown, the middle parts of the first bracket plate 5 and the second bracket plate 6 are respectively opened to the two sides and are circularly sleeved on the tower body 1. The two ends of the first bracket plate and the second bracket plate extend straight outward, and the bottom plates 13 of the grooves are abutted against each other and fixed at the fixing holes 10 with bolts 14. Figure 2 As shown, the junction between the middle open section of the first bracket plate 5 and the straight sections at both ends of the second bracket plate 6 is an arc transition, and the independent plate 7 of the upper groove wall is folded upward at the transition, and the independent plate of the lower groove wall is folded downward.
