Description

Technical Field

[0001] This invention relates to the field of antenna assembly and adjustment equipment technology, and in particular to a dedicated assembly and adjustment equipment for the front end of a phased array antenna. Background Technology

[0002] The phased array antenna front-end is a core component of the radar system, consisting of components such as the antenna frame, antenna array, TR module, AD module, signal processor, frequency synthesizer, power supply, radome, and cover plate. Its internal structure is complex, and the assembly process is lengthy. During the antenna front-end assembly, to facilitate operator work, the antenna needs to be erected at a certain height, and the antenna needs to be rotated back and forth according to the component installation sequence. Furthermore, after assembly, to verify the antenna's electrical performance, the antenna front-end needs to be transported to the field for independent debugging. Additionally, during debugging and testing, it is essential to ensure that the antenna can rotate at a certain angle in elevation.

[0003] Currently, due to the lack of dedicated assembly and debugging equipment, assembly is limited to using multiple wooden stools to support the antenna frame edges, and employing a gantry crane in conjunction with manual labor for flipping. Large equipment such as gantry cranes, forklifts, and hoists are also required during transport. Furthermore, during field testing, specialized tooling is needed to mount the antenna front end onto a general-purpose turntable to achieve pitch and rotation functionality. This antenna front end assembly and debugging process is not only inconvenient but also poses certain safety hazards. Therefore, there is an urgent need to develop a dedicated antenna front end assembly and debugging device that can both enable the erection and flipping of the antenna front end during the assembly stage and meet the needs of transport and pitch testing during independent field testing. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a dedicated assembly and adjustment device for the front end of a phased array antenna. This invention achieves the setup, flipping, and testing of the antenna front end during assembly and adjustment by installing the antenna frame between the left and right mounting plates and driving the left mounting plate to rotate via a drive mechanism, thereby rotating the antenna frame to different tilt angles.

[0037] The following describes several specific embodiments of the present invention in detail, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0038] Example

[0039] A dedicated assembly and adjustment device for the front end of a phased array antenna, see [link / reference]. Figures 1-15 As shown, it includes: a left support 2, a right support, a left mounting plate 8, a right mounting plate 18, a drive mechanism 14, and an auxiliary walking mechanism; the left support 2 and the right support are symmetrically arranged; the lower parts of the left support 2 and the right support are connected by a crossbeam 1; the left mounting plate 8 is set on the left support 2 and is rotatably connected to the left support 2 via a long shaft 6; the right mounting plate 18 is set on the right support and is rotatably connected to the right support via a short shaft 17; the left mounting plate 8 and the right mounting plate 18 are arranged opposite to each other; the drive mechanism 14 is set on the left support 2 and is connected to the long shaft 6 for transmission; auxiliary walking mechanisms are provided at the bottom of both the left support 2 and the right support.

[0040] To address this, by mounting the antenna frame between the left mounting plate 8 and the right mounting plate 18, and driving the left mounting plate 8 to rotate via the drive mechanism 14, the antenna frame can be rotated to different tilt angles. This enables the setup, flipping, and testing of the antenna front-end during assembly and adjustment. Simultaneously, auxiliary walking mechanisms are installed at the bottom of both the left and right supports, facilitating various functions such as transport during the antenna front-end assembly and adjustment process. This assembly and adjustment equipment can achieve antenna front-end setup and flipping during the assembly stage, and also meets the needs of transport and elevation testing during independent field debugging. It eliminates reliance on large equipment such as overhead cranes, forklifts, hoists, and general-purpose turntables, thus eliminating safety hazards during the assembly and adjustment process.

[0041] In this embodiment, both the left support 2 and the right support are triangular welded frames. The auxiliary walking mechanism includes casters 16 with foot brakes installed at the bottom of the left support 2 and the right support. The triangular welded frame is welded from rectangular steel pipes and its main function is to provide support for the erection and rotation of the antenna frame; the bottom rectangular steel pipe has threaded holes and is welded with nuts, which can be connected to the casters 16 and the crossbeam 1 by screws.

[0042] To enable the rotation of the left mounting plate 8 and the right mounting plate 18, a first round steel bar 21 is provided on the top of the left bracket 2; one end of the long shaft 6 is connected to the left mounting plate 8, and the other end passes through the first round steel bar 21 and is connected to the drive mechanism 14 for transmission; the first round steel bar 21 has a first through hole for the long shaft 6 to pass through; the long shaft 6 is rotatably connected to the first round steel bar 21. The drive mechanism 14 is a worm gear reducer. A second round steel bar is provided on the top of the right bracket; one end of the short shaft 17 is connected to the right mounting plate 18, and the other end is rotatably connected to the second round steel bar. Therefore, the drive mechanism 14 drives the long shaft 6 to rotate the left mounting plate 8; in addition, an antenna frame is installed between the left mounting plate 8 and the right mounting plate 18. While the left mounting plate 8 rotates, the right mounting plate 18 also rotates, further realizing the flipping of the antenna frame installed between the left mounting plate 8 and the right mounting plate 18.

[0043] In this embodiment, a step is provided in the first through hole of the first round steel 21. Similarly, a step is provided in the second through hole of the second round steel. Rolling bearings 10 are installed in both the first and second through holes. The outer ring of the rolling bearings 10 is fixed by the end cover sleeve 9. The rolling bearings 10 are sleeved on the long shaft 6 to realize the rotation of the long shaft 6. At the same time, the bearing in the second through hole is sleeved on the short shaft 17 to realize the rotation of the short shaft. In addition, the worm gear reducer is connected to the side of the first round steel 21 away from the left mounting plate 8 by the flange sleeve 12. The flange sleeve 12 is a sleeve-shaped structure with flanges on both ends, used to install the worm gear reducer 14 on the bracket 2. One end of the flange is connected to the first round steel 21 by screws, and the other end of the flange is connected to the worm gear reducer 14.

[0044] In this embodiment, the left mounting plate 8 is a rectangular aluminum plate with a circular through hole and countersunk platform in the middle, which can be connected to the long shaft 6 by screws; two countersunk holes are provided at both ends for mounting the antenna frame; scale lines and angle markings are engraved on the circumference of the central circular hole to measure the rotation angle of the antenna frame. The long shaft 6 is a drive shaft, one end of which is connected to the left mounting plate 8 via a flange, and the other end has a keyway, which can be connected to the worm gear reducer 14 via a flat key 7; the long shaft 6 has a step and retaining ring groove in the middle, and the inner ring of the rolling bearing 10 is fixed to the shaft by installing an elastic retaining ring 11. It should be noted that the worm gear reducer 14 is rotated by an external handwheel; the long shaft is driven to rotate by rotating the handwheel 13 on the worm gear reducer 14.

[0045] The installation of the right mounting plate 18 is similar to that of the left mounting plate 8. It has a circular through hole and a countersunk platform in the middle, which can be connected to the short shaft 17 by screws. There are two countersunk holes at both ends for mounting the antenna frame. The circular hole in the middle is engraved with scale lines and angle marks to measure the rotation angle of the antenna frame.

[0046] In this embodiment, it also includes a connecting rod 4 that is detachably connected at one end of the left mounting plate 8 and / or the right mounting plate 18 to the left bracket 2 and / or the right bracket. By setting the connecting rod, the antenna frame installed between the left mounting plate 8 and the right mounting plate 18 can be fixed at a certain tilt angle.

[0047] Specifically, one end of the connecting rod 4 is rotatably connected to one end of the left mounting plate 8 or the right mounting plate 18; the other end is hinged to the left bracket 2 or the right bracket via a pin; wherein, the left bracket 2 or the right bracket is provided with a hinge seat 3 for pin hinge, the hinge seat 3 is a π-shaped structure, and the connecting rod 4 is hinged to the hinge seat 3 via a pin 15; or the pin 15 can be removed to disconnect the connection between the connecting rod 4 and the hinge seat 3.

[0048] In this embodiment, the connecting rod 4 is a long strip structure with circular through holes at both ends. One end is connected to the hinge seat 3, and the other end is connected to the support seat 5 by screws. The support seat 5 is a T-shaped structure with countersunk holes at the bottom, which is screwed onto the left mounting plate 8. A threaded blind hole in the middle connects to the connecting rod 4. Threaded holes are provided in the middle of the rectangular steel tubes on both sides of the left bracket 2 and / or the right bracket for mounting the hinge seat 3.

[0049] It should be noted that the overall structure of the right bracket assembly is similar to that of the left bracket assembly. The difference is that the short shaft 17 in the right bracket assembly is a driven shaft, so there is no keyway on the short shaft 17; the structure of the right mounting plate 18 is a mirror image of the structure of the left mounting plate 8. At the same time, the right bracket assembly does not include components such as the flange sleeve 12, the worm gear reducer 14, and the handwheel 13.

[0050] In this embodiment, when assembling the antenna front end using this dedicated assembly and adjustment equipment, the antenna frame is connected to the left mounting plate 8 and the right mounting plate 18 with screws to complete the antenna frame installation. When it is necessary to flip the antenna frame, simply pull out the pin 15 on the hinge seat 3 and turn the handwheel 13 to drive the antenna frame to rotate through the worm gear reducer 14. When the antenna frame is flipped to the horizontal position, align the round hole on the connecting rod 4 with the round hole on the hinge seat 3 on the other side and insert the pin 15 to realize the flipping process in the antenna front end assembly. Since the bottom of the bracket 2 is equipped with casters, it meets the transfer function in the independent field debugging process. In the field debugging process of the antenna front end, simply pull out the pin 15 on the hinge seat 3 and turn the handwheel 13. Through the scale indication on the left mounting plate 8 and the right mounting plate 18, the antenna front end can be rotated at a certain angle in the pitch direction.
