Description

Technical Field

[0001] The present invention relates to a mounting bracket, and particularly to a mounting bracket for a phased array antenna array. Background Art

[0002] A phased array antenna refers to an antenna that changes the pattern shape by controlling the feeding phases of each radiation element in the array antenna. By adjusting the phase, the pointing direction of the maximum value of the antenna pattern can be changed to achieve the purpose of beam scanning. The antenna mount is a device that supports the antenna structure and enables it to move within a specified airspace. It makes the antenna move according to a predetermined law or follow the target through the antenna control system, and can accurately measure the angle of the antenna pointing through the axis position detection device, thereby determining the azimuth of the target.

[0003] During the use of the antenna, due to long-term use or damage to the antenna itself, repairs or maintenance may be required. When performing such operations, due to the differences in the array size and volume of the phased array antenna, the existing mounting bracket can only drive the antenna array for angle adjustment and rotation. When repairing a larger antenna array, it may be necessary for workers to climb directly onto the mounting panel of the antenna to operate. This is not only inconvenient for operation, but may also accidentally damage other components on the mounting panel during the repair process. Summary of the Invention

Detailed Description of the Invention

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] A mounting bracket for a phased array antenna array, as Figures 1 - 5 shown, includes a bottom plate 1, a connecting plate 2, guiding rails 3, a mounting frame 4, a mounting seat 5, a movable block 6, a driving motor 7, and a lifting mechanism. A driving motor 7 is installed in the middle of the bottom plate 1. A connecting plate 2 is connected to the output shaft of the driving motor 7. Guiding rails 3 are installed on both the left and right sides of the top of the connecting plate 2. Movable blocks 6 are arranged on both guiding rails 3. The movable blocks 6 can slide and rotate within the guiding rails 3. A mounting frame 4 is movably connected between the two movable blocks 6. A mounting seat 5 is rotatably connected to the right side of the top of the mounting frame 4. The phased array antenna can be installed on the mounting seat 5. A lifting mechanism for lifting the mounting seat 5 is provided on the connecting plate 2.

[0029] As Figure 4 and Figure 5 shown, the lifting mechanism includes a driving cylinder 81, a pushing shaft 82, a swinging plate 83, a sliding block 84, and a connecting seat 87. The driving cylinder 81 is installed on the left side of the connecting plate 2. The driving cylinder 81 is inclined with the left side lower and the right side higher. A pushing shaft 82 is connected to the telescopic rod of the driving cylinder 81. A connecting seat 87 is installed on the right side of the connecting plate 2. A swinging plate 83 is rotatably connected to the connecting seat 87. A sliding block 84 for pushing the mounting seat to move is hinged to the swinging plate 83. The pushing shaft 82 is located below the swinging plate 83 and contacts the bottom of the swinging plate 83, so that the pushing shaft 82 can push the swinging plate 83 to swing upward along the connecting seat 87 when moving. A longitudinally arranged sliding groove 85 and a laterally arranged pushing groove 86 are formed at the bottom of the mounting seat 5. The front and rear sides of the sliding groove 85 extend to the front and rear side walls of the mounting seat 5 respectively. The pushing groove 86 is located in the middle of the right side of the sliding groove 85 and communicates with the sliding groove 85. The sliding block 84 is located in the pushing groove 86 and can slide along the pushing groove 86. The mounting seat 5 can slide along the sliding block 84 through the sliding groove 85 when sliding.

[0030] When the antenna mounting base 5 is needed to be used, the phased array antenna can be mounted on the top of the mounting base 5. After the installation is completed, the telescopic rod of the driving cylinder 81 can be controlled to extend to drive the push shaft 82 to move to the right. When the push shaft 82 moves to the right, it pushes the bottom of the swing plate 83, so that the swing plate 83 swings upward. When the swing plate 83 swings, it can drive the sliding block 84 to move, so that the sliding block 84 pushes up the mounting base 5. When the sliding block 84 moves, the sliding block 84 will slide along the push groove 86, so that the state between the mounting base 5 and the mounting frame 4 is as Figure 4 shown, to adjust the angle of the mounting base 5. When the orientation of the mounting base 5 needs to be adjusted, the driving motor 7 is controlled to drive the connecting plate 2 to rotate, and then the orientation of the mounting base 5 can be adjusted to adjust the angle of the antenna, realizing the adjustment of various angles, so as to adjust the scanning direction of the antenna. When an antenna is damaged and needs to be repaired, the telescopic rod of the driving cylinder 81 can be controlled to retract first, so that the mounting base 5 swings downward and resets under the action of gravity. At this time, the sliding block 84 is located in the sliding groove 85. Then, the mounting base 5 is pulled to slide along the guiding track 3 through the mounting frame 4 and the movable block 6. Since the sliding block 84 is located in the sliding groove 85, it will not hinder the movement of the mounting base 5. If the damaged antenna is in the front, the mounting base 5 is pulled to slide forward. If the damaged antenna is in the back, the mounting base 5 is pulled to slide backward. After the mounting base 5 and the mounting frame 4 move to the end of the guiding track 3, the mounting base 5 can be pulled to swing downward, and then the maintenance work of the antenna can be carried out. After the maintenance is completed, the mounting base 5 is pulled to swing upward and reset, and then the mounting base 5 is pulled to slide and reset. In this way, the antenna mounting base 5 can be used. And when in use, if an antenna is damaged, the mounting base 5 can be controlled to move out of the equipment for maintenance, without the need for manual climbing to the mounting surface for operation, and the operation is more convenient.

[0031] As Figures 6 - 8 shown, it further includes a driving mechanism. The driving mechanism includes a rack 91, a servo motor 92 and a gear 93. Both the left and right sides of the bottom of the mounting base 5 are connected with a rack 91. The servo motors 92 are installed on the front and back sides of both guiding tracks 3. A gear 93 is connected to the output shaft of the servo motor 92. The gear 93 meshes with the rack 91.

[0032] When it is necessary to control the mounting base 5 to slide forward, the front servo motor 92 is controlled to drive the gear 93 to rotate to drive the rack 91 to move forward, so as to drive the mounting base 5 to slide forward. On the contrary, when it is necessary to control the mounting base 5 to slide backward, the rear servo motor 92 is controlled to drive the gear 93 to rotate to drive the rack 91 to move backward, so as to drive the mounting base 5 to slide backward. In this way, the effect of automatically driving the mounting base 5 to slide can be achieved, and the operation is more convenient.

[0033] As Figures 6 - 8As shown, it further includes a pushing mechanism. The pushing mechanism includes an electric push rod 94 and a pushing plate 95. Electric push rods 94 are installed on both the front and rear sides of the left guiding track 3. Pushing plates 95 are connected to the telescopic rods of the two electric push rods 94. The pushing plate 95 can push the swung mounting seat 5 flat.

[0034] When it is necessary to pull the mounting seat 5 to swing upward, the telescopic rod of the electric push rod 94 can be controlled to extend to drive the pushing plate 95 to move. When the pushing plate 95 moves, it can squeeze the mounting seat 5 to swing upward, as Figure 8 shown. Until the pushing plate 95 swings upward to its original position, at this time, the rack 91 on the pushing plate 95 also meshes with the gear 93. Then, control the servo motor 92 to drive the gear 93 to rotate, so as to drive the rack 91 and the pushing plate 95 to reset. In this way, the swing plate 83 can be automatically operated to swing upward. When operating, there is no need to manually pull the swing plate 83 to swing upward, making the operation more convenient.

[0035] As Figure 9 shown, it further includes a locking cylinder one 101 and a locking shaft one 102. Locking cylinders one 101 are installed on the left parts of the front and rear sides of the mounting frame 4. Slots are opened on the left sides of the front and rear sides of the mounting seat 5. A locking shaft one 102 is connected to the telescopic rod of the locking cylinder one 101. When the telescopic rod of the locking cylinder one 101 extends, it can drive the locking shaft one 102 to move and insert into the slot to fix the mounting seat 5 and prevent the mounting seat 5 from swinging upward, thus playing a role in locking the mounting seat 5. When it is necessary to control the mounting seat 5 to swing upward, control the telescopic rod of the locking cylinder one 101 to retract to drive the locking shaft one 102 to reset.

[0036] As Figure 10 shown, it further includes a locking cylinder two 121 and a locking shaft two 122. A slot is opened at the middle position on the right side of the mounting frame 4. A locking cylinder two 121 is installed at the middle position on the right side of the connecting plate 2. A locking shaft two 122 is connected to the telescopic rod of the locking cylinder two 121. When the telescopic rod of the locking cylinder two 121 extends, it drives the locking shaft two 122 to move upward and insert into the slot, thereby locking the mounting frame 4 and preventing the mounting frame 4 from sliding randomly. When it is necessary to control the mounting frame 4 to slide back and forth, control the telescopic rod of the locking cylinder two 121 to retract to drive the locking shaft two 122 to move downward and disengage from the slot. At this time, the mounting frame 4 can be pulled to slide. In this way, the effect of locking the mounting frame 4 can be achieved.

[0037] As Figure 11As shown in the figure, it further includes a cleaning mechanism. The cleaning mechanism includes an electric guide rail 131, a connecting frame 132, a fan 133 and a blowing air pipe 134. Electric guide rails 131 are installed on both the front and rear sides of the top of the mounting base 5. A connecting frame 132 is connected between the moving bodies of the two electric guide rails 131. A fan 133 is installed on the connecting frame 132. A plurality of blowing air pipes 134 are installed at intervals at the bottom of the fan 133.

[0038] After long-term use, some impurities may adhere to the antenna of the mounting base 5. At this time, the fan 133 can be controlled to operate to blow air through the blowing air pipe 134 to blow out the impurities adhering to the antenna, so as to achieve the effect of cleaning the impurities. After the cleaning is completed, the fan 133 can be controlled to turn off.
