Description

Technical Field

[0001] This utility model relates to the field of signal equipment installation technology, and in particular to a signal amplifier mounting bracket. Background Technology

[0002] Tunnels are mostly enclosed reinforced concrete structures, which shield electromagnetic waves and affect wireless signals. Amplifiers can receive weak signals from external base stations or signal sources, filter, reduce noise, and amplify the power before retransmitting, extending signal coverage. This ensures uninterrupted communication for emergency systems such as fire fighting and public security within the tunnel, supporting rapid response to emergencies. It also provides stable signals for mobile phone calls, internet access, vehicle navigation, ETC (Electronic Toll Collection), and emergency calls, preventing accidents caused by signal loss.

[0003] Inside the tunnel, signal amplifiers are typically fixed with individual expansion bolts. Because of the single-bolt structure, the installation angle of the signal amplifier is prone to tilting after being subjected to gravity for a long time. This not only seriously affects the passage of the tunnel, but also poses a risk of falling off, creating a safety hazard for people passing by. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a signal amplifier mounting bracket, including a channel steel plate 11, a back plate 21 at the upper end of the channel steel plate 11, a plurality of first bolt holes 22 on the back plate 21, and a steel channel 12 on the back of the channel steel plate 11.

[0030] Connecting brackets are symmetrically installed at the left and right ends of the channel steel plate 11. The connecting brackets include two support plates 31. One end of the support plate 31 is fixedly installed inside the steel channel 12, and the other end of the support plate 31 is fixedly installed with a first bolt plate 32. A second bolt hole 33 is opened on the first bolt plate 32.

[0031] The signal amplifier mounting bracket is installed inside the transport corridor, at a height of 3 meters on the 6.3-meter diameter arc-shaped tunnel wall, spaced 500 meters apart. The connecting bracket is used to connect to the wall. The support plate 31 on the connecting bracket is fixed to the channel steel plate 11 by welding. When fixing to the wall, the fixing bolt installed in the second bolt hole 33 is connected to the bolt hole opened on the wall. The U-shaped support plate 31 can play a buffering role.

[0032] The left and right ends of the channel steel plate 11 are symmetrically equipped with brackets, the brackets include angle steel brackets A41, one end of the angle steel brackets A41 is fixedly set on the corner of the front of the channel steel plate 11, and the other end of the angle steel brackets A41 is provided with a limiting clamp.

[0033] The limiting clamp includes two second bolt plates 42, which are fixedly installed on the upper end of the angle steel support plate A41. There is a gap between the two second bolt plates 42 for placing a signal device, and a third bolt hole 43 is opened on the second bolt plate 42.

[0034] The signal amplifier is placed on two angle steel support plates A41, which support the signal amplifier. The second bolt plate 42 on the angle steel support plate A41 is fastened to the signal amplifier from both the left and right ends by fixing bolts. The back plate 21 is connected to the back of the signal amplifier by another set of fixing bolts, ensuring that the various connection surfaces of the signal amplifier can be evenly stressed, have good impact resistance, and will not fall off.

[0035] Please see Figure 1 and Figure 2 In Example 1:

[0036] The back plate 21 is integrally formed with the channel steel plate 11. An angle steel support plate B51 is provided on the back of the back plate 21. One end of the angle steel support plate B51 is fixedly connected to the back plate 21, and the other end of the angle steel support plate B51 is fixedly set inside the steel channel 12. The back plate 21 is integrally formed with the channel steel plate 11 by sheet metal cutting. The advantage of this design is that the overall structure is simple and easy to process. The angle steel support plate B51 set on the back of the back plate 21 and inside the channel steel plate 11 can act as a reinforcing rib, supporting the back plate 21 from the back and ensuring that the back plate 21 will not bend.

[0037] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 In Example 2:

[0038] The upper end of the channel steel plate 11 is provided with a groove 13, the back plate 21 is engaged with the groove 13, and a first positioning part is provided at the engagement point of the back plate 21 and the groove 13.

[0039] An angle steel support plate C52 is provided on the back of the channel steel plate 11. One end of the angle steel support plate C52 is fixedly installed inside the steel channel 12. An angle steel support plate D53 is provided on the back of the back plate 21. One end of the angle steel support plate D53 is fixedly connected to the second bolt plate 42. The other end of the angle steel support plate D53 is inserted into the angle steel support plate C52 and slidably connected to the angle steel support plate C52. A second positioning part is provided at the connection between the angle steel support plate D53 and the angle steel support plate C52.

[0040] After the back plate 21 is inserted into the groove 13, the first positioning part will limit the back plate 21. The angle steel support plate D53 on the back of the back plate 21 is inserted into the angle steel support plate C52 on the inner side of the channel steel plate 11. The second positioning part limits the angle steel support plate D53. The angle steel support plate C52 cooperates with the angle steel support plate D53 to support the back plate 21 from the back, thereby improving the impact resistance of the back plate 21.

[0041] The back plate 21 is fixed to the channel steel plate 11 in a detachable connection manner. When the back plate 21 is deformed during transportation, making it difficult for the signal device to match effectively, the back plate 21 can be directly pulled out from the top of the channel steel plate 11 for replacement by releasing the first positioning part from the limiting position of the channel steel plate 11 and the back plate 21, and the second positioning part from the limiting position of the angle steel support plate C52 and the angle steel support plate D53. The split design facilitates subsequent maintenance.

[0042] Specifically, the first positioning part includes multiple positioning bolts 54, which are fixedly disposed at the lower end of the back plate 21. The positioning bolts 54 are slidably connected to the positioning holes 55 opened inside the groove 13. When the back plate 21 is inserted into the groove 13, the positioning bolts 54 at the bottom of the back plate 21 will also engage with the various positioning holes 55 opened inside the groove 13. The positioning bolts 54 perform initial positioning of the back plate 21 by cooperating with the positioning holes 55.

[0043] Specifically, the second positioning part includes a positioning bolt 54 mounted on the outside of the angle steel support plate C52. The positioning bolt 54 passes through the angle steel support plate C52 and is threadedly connected to the angle steel support plate C52. A positioning hole 55 is opened on the outside of the angle steel support plate D53, and the positioning hole 55 is threadedly connected to the positioning bolt 54.

[0044] When the angle steel support plate D53 is fully inserted into the angle steel support plate C52, the positioning hole 55 on the outside of the angle steel support plate D53 will coincide with the positioning bolt 54 installed on the outside of the angle steel support plate C52. By screwing the positioning bolt 54 into the positioning hole 55 on the outside of the angle steel support plate C52, the fixation between the angle steel support plate C52 and the angle steel support plate D53 can be completed, and the channel steel plate 11 and the back plate 21 are also fixed.

[0045] How this application works:

[0046] The signal amplifier mounting bracket is installed inside the transport corridor, at a height of 3 meters on the 6.3-meter diameter arc-shaped tunnel wall, spaced 500 meters apart. The connecting bracket is used to connect to the wall. The support plate 31 on the connecting bracket is fixed to the channel steel plate 11 by welding. When fixing to the wall, the fixing bolt installed in the second bolt hole 33 is connected to the bolt hole opened on the wall. The signal amplifier is placed on two angle steel support plates A41, which support the signal. The second bolt plate 42 on the angle steel support plate A41 is fastened to the signal from the left and right ends of the signal through fixing bolts. The back plate 21 is connected to the back of the signal amplifier through another set of fixing bolts, ensuring that the various connection surfaces of the signal amplifier can be evenly stressed, have good impact resistance, and will not fall off.
