Detailed Description
The structural features of the present invention will now be described with reference to the accompanying drawings:
the antenna box body 1 is formed by sequentially welding a plurality of sections of segmented box bodies 11, and each segmented box body 11 is formed by oppositely welding the opening ends of two U-shaped box body plates.
As shown in fig. 2, firstly, welding a single box body, namely, bending two aluminum alloy plates into a U shape, then opening a maintenance window on one box body, arranging a first cover plate 12 at the position of the maintenance window, then fixing the U-shaped aluminum alloy plates on a working platform of a semi-automatic welding device, and inputting process parameters to complete the welding operation of the segmented box body 11. After the single box body is welded, the two segmented box bodies 11 are fixed on a welding platform, the staggered ends of the two segmented box bodies 11 are meshed with each other, arc welding is used for welding, cross welding seams cannot occur due to the fact that the welding seams are staggered, and the whole box body edge is corrected and subjected to stress treatment after welding. Because the welding technology of single-side welding and double-side forming is adopted, the welding difficulty can be reduced, and the welding speed can be improved.
As shown in fig. 1, the four segmented boxes 11 are welded to form an antenna box 1, and after the welding of the antenna box 1 is completed, second cover plates 13 are disposed at maintenance windows at two ends of the antenna box 1. Two hoisting support lugs 14 are arranged at the upper end of the antenna box body 1. A leveling reference plate is arranged on the end surface of the antenna box body 1 between the two hoisting support lugs 14, and a protection plate 15 is covered on the leveling reference plate. A fixed support plate 17 is installed at the lower ends of the two segment boxes 11 located in the middle of the antenna box 1. Two antenna mounting plates 2 are mounted on the end face of the antenna box 1, and a backfeed mounting plate 19 is mounted on the end face of the antenna box 1 facing away from the antenna mounting plates 2.
After the components on the surface of the antenna housing 1 are mounted, the support frame 4 is mounted on the fixed support plate 17 of the antenna housing 1. When the support frame 4 is installed, the protection plate 15 can be opened, and the level gauge is placed on the leveling reference plate for detecting the surface accuracy of the antenna box body 1. Because the antenna has higher requirement on the surface precision of the antenna box body 1, the surface precision difference of two ends of the antenna box body 1 cannot exceed one millimeter of zero, otherwise, the receiving and sending signals of the antenna are influenced. When the positions of the two supports of the support frame 4 are adjusted, the surface precision of the antenna box body 1 can be measured through the level meter at any time until the level meter points to the zero scale mark, and the debugging of the support frame 4 is completed. After the antenna case 1 is leveled, the radar antenna 3 is mounted to the antenna mounting plate 2. As shown in fig. 5, a backfeed antenna is mounted on the backfeed mounting plate 19, and the backfeed antenna can prevent ground clutter from interfering with the secondary radar antenna.
After the radar antenna 3 and the support frame 4 are mounted on the antenna box 1, as shown in fig. 3 and 4, the hoisting mechanism acts on the hoisting lug 14, so that the whole device can complete the erection of the antenna box 1. Moreover, the hoisting support lug 14 is positioned in the middle area of the antenna box body 1, so that the antenna box body can be prevented from shaking indefinitely in the hoisting process.
The segmented box body 11 is formed by welding aluminum alloy plates, the whole antenna box body 1 adopts a welding processing technology, an assembly mode of manual riveting is replaced, the influence of human factors is reduced, and batch production is realized. Meanwhile, the number and the types of parts are reduced by a welding installation mode, and the number and the types of the parts of the antenna box body 1 are respectively reduced by 80% and 60%, so that the installation complexity is reduced, and the production period is shortened. In addition, due to the reduction of the number of parts and the types of the parts, the phenomenon of wrong installation caused by the use of too many parts is avoided, and the installation accuracy is further improved. Moreover, most parts of the antenna box body 1 are made of aluminum alloy, so that the density of the aluminum alloy is low, the weight is light, the whole weight is reduced by 50%, the weight of the box body is reduced, and the strength requirement on a mounting base is lowered.
As shown in fig. 3 and 6, the antenna mounting plate 2 of the present invention provides a mounting platform for the secondary radar antenna, and the control line of the secondary radar antenna is introduced into the antenna housing 1 through the through hole formed in the housing and connected to the control instrument inside the antenna housing 1. The junction of the control line and the through hole is filled with an antenna sealing assembly 16 which can play a good role in waterproof sealing.
As shown in fig. 4, the maintenance windows at the two ends of the antenna box body 1 and the box body make it convenient for the staff to overhaul the control instruments inside the antenna box body 1, and the maintenance windows are covered by the first cover plate 12 and the second cover plate 13 respectively, so that the box body is in a closed state and the antenna control instruments inside are protected.
As shown in fig. 5, the waterproof vent plugs 18 of the present invention are distributed near the welding area, and since the waterproof vent plugs 18 sequentially increase from the aperture inside the antenna housing 1 to the aperture outside the antenna housing 1, and the waterproof vent plugs 18 are provided with waterproof vent films inside, when the temperature inside the antenna housing 1 rises, the exchange of the inside and outside temperature is realized through the waterproof vent plugs 18, so as to reduce the temperature inside the antenna housing 1, and further protect the control instruments inside the antenna housing 1. Meanwhile, the increase of pressure intensity caused by the rise of temperature can be prevented, and the loosening of the welding position is avoided. Not only can play the role of preventing rainwater from entering, but also can balance the internal and external pressure difference of the antenna box body 1 and avoid the respiratory effect.
As shown in fig. 4 and 5, the support frame 4 for supporting the antenna box 1 is mounted on the antenna box 1 through the support plate 17, and the bolt for fixing the support plate 17 is filled with sealant, so that rainwater can be prevented from entering the box.
Preferably, as shown in fig. 7, a vertical angle adjusting mechanism 5 is provided between the antenna case 1 and the radar antenna 3. When the installation ground is uneven, as shown in fig. 8, the adjusting plate 51 is driven by the motor to form an angle between the adjusting plate 51 and the antenna case 1, so that the radar antenna 3 is in a vertically placed state, and then the adjusting plate 51 is fixed to the adjusting member 52 by the fastening member 53. Vertical angle adjustment mechanism 5 can be applicable to the uneven circumstances in ground, through the contained angle of adjusting vertical angle adjustment mechanism 5, still makes the vertical placing of radar antenna 3, guarantees that radar antenna 3 can normally send and receive signals.
