Description

Technical Field

[0001] This invention relates to the field of antennas, and more particularly to tunnel antenna installation technology, especially an antenna mounting bracket adapted to the harfen trench of a subway tunnel. Background Technology

[0002] With the development of urban rail transit and the improvement of living standards, people have increasingly higher requirements for communication coverage inside subway tunnels. Currently, the main technologies for subway coverage are leaky cable and communication antenna coverage. Subway tunnel sidewalls have pre-reserved H-channels for installing and fixing cables and equipment. The spacing between adjacent H-channels is generally fixed at 1.2 meters. In existing technology, conventional electrical equipment is mostly installed back-to-the-tunnel sidewall and fixed to the H-channels by crossbeams. However, communication antennas are different from these conventional devices. Communication antennas need to be installed sideways, not against the wall, and are fixed using clamps. If antennas are installed inside subway tunnels in the traditional way, on-site surveys are required to determine the fixed position of the antenna brackets. The installation can only proceed after surveying and marking out the locations, which is time-consuming and labor-intensive. Furthermore, the installation requires the combined use of bolts and clamps, resulting in a complex installation structure, cumbersome operation, and impacting overall safety and reliability. Summary of the Invention

[0003] The purpose of this invention is to provide an antenna mounting bracket adapted to the sluice gate of a subway tunnel. This antenna mounting bracket adapted to the sluice gate of a subway tunnel aims to solve the technical problems in the prior art of installing antenna brackets in subway tunnels, such as time-consuming and labor-intensive installation, complex installation structure, cumbersome operation, and impact on overall safety and reliability.

[0004] The present invention discloses an antenna mounting bracket adapted for a halfen slot in a subway tunnel, comprising two parallel and spaced crossbeams. Each crossbeam has a halfen slot fixing hole at both ends. Each of the two crossbeams has at least two first mounting holes spaced along its length on its side. Each of the two crossbeams has a support frame connected to one side through the first mounting holes and bolts. The two support frames are parallel to each other and perpendicular to the crossbeams. Each of the two support frames has at least two second mounting holes spaced along its length on its side. Each of the two support frames has an antenna mounting frame connected to one side through the second mounting holes and bolts. The two antenna mounting frames are parallel to each other and perpendicular to the support frames. Each of the two antenna mounting frames has at least two third mounting holes spaced along its length.

[0005] Furthermore, the support frame includes a first bracket and a second bracket. The first bracket is connected to the crossbeam frame and the length direction of the first bracket is parallel to the length direction of the crossbeam frame. The second bracket is perpendicularly connected to the first bracket. A second mounting hole is provided on the second bracket. A reinforcing rib bracket is connected between the second bracket and the first bracket.

[0006] Furthermore, both the first and second supports are made of angle steel.

[0007] Furthermore, the reinforcing rib support is made of flat iron profiles.

[0008] Furthermore, the antenna mounting bracket includes two connecting plates and a connecting frame. The two ends of the connecting frame are respectively connected to the two connecting plates, and the two connecting plates are respectively connected to the two support frames. A third mounting hole is provided on the connecting frame.

[0009] Furthermore, the connecting plate is a 6mm thick steel plate.

[0010] Furthermore, the connecting frame is made of angle steel.

[0011] Compared with existing technologies, the advantages of this invention are positive and significant. This invention provides an antenna mounting bracket adapted for use in subway tunnel ducts, enabling the antenna to be securely and reliably fixed to the duct. All structural components can be prefabricated in the factory, allowing for rapid on-site adjustment and installation for immediate use. It eliminates the need for on-site measurement and layout, and the use of antenna fixing steel pipes and clamps, reducing the types and number of bracket parts, improving construction efficiency, significantly enhancing overall safety and reliability, and reducing costs.

Any similar structures and similar variations of the present invention should be included within the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of description and is not intended to limit the technical solution of the present invention.

[0019] like Figures 1-6 As shown, an antenna mounting bracket adapted for a halfen slot in a subway tunnel according to the present invention includes two parallel and spaced-apart crossbeams 1. Each of the two crossbeams 1 has a halfen slot fixing hole 13 at both ends. Each of the two crossbeams 1 has at least two first mounting holes 2 spaced apart along its length on its side. Each of the two crossbeams 1 has a support frame 3 connected to one side through the first mounting hole 2 and bolts. The two support frames 3 are parallel to each other and perpendicular to the crossbeams 1. Each of the two support frames 3 has at least two second mounting holes 4 spaced apart along its length on its side. Each of the two support frames 3 has an antenna mounting frame 5 connected to one side through the second mounting hole 4 and bolts. The two antenna mounting frames 5 are parallel to each other and perpendicular to the support frames 3. Each of the two antenna mounting frames 5 has at least two third mounting holes 6 spaced apart along its length.

[0020] Furthermore, the support frame 3 includes a first bracket 7 and a second bracket 8. The first bracket 7 is connected to the crossbeam frame 1 and the length direction of the first bracket 7 is parallel to the length direction of the crossbeam frame 1. The second bracket 8 is perpendicularly connected to the first bracket 7. The second mounting hole 4 is provided on the second bracket 8. A reinforcing rib bracket 9 is connected between the second bracket 8 and the first bracket 7.

[0021] Furthermore, both the first bracket 7 and the second bracket 8 are made of angle steel.

[0022] Furthermore, the reinforcing rib bracket 9 is made of flat iron profile.

[0023] Furthermore, the antenna mounting bracket 5 includes two connecting plates 10 and a connecting frame 11. The two ends of the connecting frame 11 are respectively connected to the two connecting plates 10, and the two connecting plates 10 are respectively connected to the two support frames 3. The third mounting hole 6 is provided on the connecting frame 11.

[0027] The working principle of this embodiment is as follows: During on-site installation, the two sets of crossbeam frames 1 are first fixed at a certain interval on the halfen groove 12 of the tunnel inner wall. Then, the support frame 3 and the antenna fixing frame 5 are assembled on the crossbeam frame 1. The antenna is fixed on the antenna fixing frame 5 by bolts and the third mounting hole 6.

[0028] The present invention provides an antenna mounting bracket adapted to the sluice gate of a subway tunnel, which enables the antenna to be securely and reliably fixed on the sluice gate 12. Each structural component can be prefabricated in the factory and can be adjusted and installed on site for rapid use. There is no need for on-site measurement and layout, and no need to use antenna fixing steel pipes and clamps. This reduces the types and number of bracket parts, improves construction efficiency, greatly improves overall safety and reliability, and reduces costs.
