Description

Technical Field

[0001] This utility model relates to the field of antenna assembly auxiliary tools, and in particular to a tooling for assembling and fixing circular array antennas. Background Technology

[0002] A circular array antenna is an array antenna in which antenna elements are arranged in a grid pattern on a planar disk. Unlike linear arrays and rectangular planar arrays, its boundary is circular. Circular array antennas are mainly used in radar and communication fields. Their symmetrical structure allows the beam to be seamlessly and quickly scanned electronically and covered in all directions within a 360-degree plane. Compared with planar arrays of other shapes, the circular boundary can accommodate the most elements within a limited aperture, and the structure is more balanced and stable.

[0003] Currently, the installation and support of circular array antennas typically involves evenly installing support blocks or columns at 4-6 points on the bottom of the antenna to support and fix it, thus facilitating further assembly and wiring. However, the current support structure has several problems: First, during assembly and wiring on the surface of the array antenna, safety accidents can easily occur due to insufficient strength and reliability of the support columns. Second, since some modular components are usually installed on the back and front of the array antenna, the support columns used for support need to avoid these components, but in actual applications, it is often impossible to completely avoid them, leading to installation inconvenience. Finally, when equipping components on the back of the array antenna, special equipment (cranes or overhead cranes) is usually required to flip and re-support it, which is troublesome, laborious, inefficient, and inconvenient to operate.

[0004] Therefore, based on the shortcomings of the existing device, the inventors made further improvements to overcome the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for assembling and fixing circular array antennas that can adjust the tilt angle of the array antenna to facilitate the assembly of components, provide stable and reliable support, and improve the overall assembly efficiency.

[0006] The purpose of this utility model is achieved through the following technical solution: A tooling for assembling and fixing a circular array antenna, comprising an array antenna, a fixing plate, an adjusting plate, and a rotating mounting plate; The area array antenna is connected to a fixed plate on each of its left and right sides, and the area array antenna is rotatably connected to the brackets set on the left and right sides via the fixed plates themselves; the brackets on the left and right sides are provided with adjustment plates on the side facing the area array antenna, and the adjustment plates are provided with arc-shaped grooves. At the same time, the lower left and right sides of the area array antenna are respectively connected to and fixed to a rotating mounting plate. The rotating mounting plate is provided with a sliding rod, which slides into the arc-shaped groove and is locked and fixed to the adjustment plate after the pitch angle of the area array antenna is adjusted. After the area array antenna is rotatably installed in the brackets on the left and right sides by fixing the plate, the rotating mounting plate is installed and fixed to the area array antenna. The slide rod of the rotating mounting plate is inserted into the arc groove in the adjustment plate. According to the assembly needs, the slide rod slides in the arc groove to adjust the elevation angle of the area array antenna and lock it in place.

[0007] As a preferred technical solution of this application, the top of the bracket is provided with a mounting seat, and the mounting seat has a pin hole. The fixing plate is inserted into the bracket through the pin hole, and the fixing plate can rotate around the bracket, thereby driving the area array antenna connected to the fixing plate to rotate.

[0008] As a preferred technical solution of this application, the bracket is a triangular bracket, and the lower parts of the symmetrically arranged left and right brackets are connected by a long rod that can be extended and shortened. At the same time, rollers are installed on the lower surface of the bottom of the bracket, so as to adapt to different diameters of the area array antenna. The brackets are moved to the left and right by the rollers to adjust the distance between the two brackets.

[0009] As a preferred technical solution of this application, the fixing plate includes an arc panel and a frame A. The frame A is a convex frame structure and a positioning pin is opened in the center of the frame A. The positioning pin is inserted into the pin hole of the bracket and locked, so that the fixing plate and the bracket are rotatably connected. The arc panel is fixedly connected to the edge of the frame A. The inner arc surface of the arc panel is adapted to fit the arc end surface of the array antenna, and the two are fixed by bolts.

[0010] As a preferred technical solution of this application, the rotating mounting plate includes an L-shaped plate and a sliding rod; the opening on the side plate of the L-shaped plate is connected to the mounting hole on the edge of the array antenna by bolts, and the bottom plate of the L-shaped plate is connected to the sliding rod, which is movably inserted into the arc groove of the adjustment plate.

[0011] As a preferred technical solution of this application, the adjustment plate includes a frame B, which is a rectangular frame and its bottom end is fixedly connected to a support. A rectangular plate is connected to the other end of the frame B, and an arc-shaped slot is opened in the rectangular plate. When the array antenna is rotated back and forth, the slide rod slides in the arc-shaped slot until the array antenna is tilted to a suitable angle. Then, the slide rod is locked and fixed in the arc-shaped slot at that position to prevent tipping.

[0012] This utility model has the following advantages: (1) Adjusting and fixing the tilt angle of the array antenna makes it easier to install the device; First, the circular array antenna is connected to the rotating mounting plate through its original mounting holes. At the same time, the sliding rod of the rotating mounting part is inserted into the arc groove of the adjustment plate. By sliding the sliding rod, the circular array antenna can be tilted at a certain angle to achieve the tilt angle control of the array antenna. This avoids the need for repeated flipping and hoisting during the assembly of the front and back of the array, making it more convenient, time-saving and labor-saving to assemble the components on the array antenna, thus improving the overall assembly efficiency. (2) Effectively avoids affecting the installation position of the device on the array antenna and has stronger applicability; Compared to ordinary support columns, the fixing plate selected in this solution is connected to the bracket through positioning pins. The fixing plate is connected to the circular array antenna through its side, thereby supporting it and avoiding the situation where the support column cannot avoid the position of the installation module components, which would cause installation inconvenience. At the same time, by changing the spacing between the symmetrically set brackets, it can be adapted to the auxiliary assembly of array antennas of different diameters, making it more versatile.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0015] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0017] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a tooling for assembling and fixing circular array antennas to solve the problem.

[0018] See Figures 1 to 7 The present embodiment proposes a tooling for assembling and fixing a circular array antenna, including a fixing plate for connecting the array antenna 1 to the bracket 2, as well as an adjustment plate and a rotating mounting plate. Among them, see Figure 1 The array antenna 1 is suspended in the brackets 2 on the left and right sides by a fixing plate, and the array antenna 1 itself can rotate, so as to facilitate the adjustment of the tilt angle of the array antenna 1 in order to achieve the purpose of installing devices in front of and behind the array antenna 1. Among them, see Figure 2 and Figure 3 An adjustment plate is installed on the side of the bracket 2 facing the area array antenna 1, and an arc-shaped groove 6 is provided in the adjustment plate. The area array antenna 1 is provided with a rotating mounting plate corresponding to the left and right adjustment plates. A sliding rod 7 extends out of the rotating mounting plate, passes through the arc-shaped groove 6, and can slide along the arc-shaped groove 6. After swinging the area array antenna 1 back and forth to adjust the pitch angle of the area array antenna 1, the end of the sliding rod 7 at this position is locked and fixed to maintain the tilt angle of the area array antenna 1 so that the devices can be installed on the front and rear surfaces. First, connect the area array antenna 1 to the fixing plate and then connect the fixing plate to the bracket 2. The area array antenna 1 is rotatably installed in the brackets 2 on the left and right sides through the fixing plate. Then, rotate the mounting plate to install the area array antenna 1. At this time, the sliding rod 7 of the rotating mounting plate is inserted into the arc-shaped groove 6. The elevation angle of the area array antenna 1 is adjusted according to the position of the components to be assembled. After adjustment, the sliding rod 7 is locked and fixed to prevent movement or shaking.

[0019] Currently, the support frames used to assist in the installation of circular array antenna 1 are often simple support blocks or support columns, which are evenly installed at the bottom of the array antenna 1. However, this support method has some problems: First, the support columns will block some positions on the back of the array antenna 1, making it inconvenient to install components. Furthermore, when equipping components on the back, it is necessary to use a hoisting method to flip and re-support the antenna before installation, which is troublesome, laborious, and has low assembly efficiency. Based on the above problems, this solution designs a tooling for assembling and fixing the circular array antenna 1. This tooling, through the cooperation of bracket 2 and fixing plate, suspends and fixes the array antenna 1 on the ground from the side, avoiding obstruction of the front and rear surfaces of the array antenna 1. Moreover, through the fitting insertion of the sliding rod 7 and the arc groove 6 in the rotating mounting plate, the array antenna 1 can achieve forward and backward tilting movements, thus allowing it to be flipped without hoisting for component installation.

[0020] In this embodiment, see Figures 1-3 For bracket 2, which is a triangular bracket 2, it can stably support the array antenna 1 on the ground. Two sets of symmetrical brackets 2 are set on the left and right sides of the array antenna 1. A mounting base is set at the top end of the bracket 2. The mounting base has a pin hole, and the fixing plate has a corresponding positioning pin 5. The fixing plate is connected to the bracket 2 by inserting the positioning pin 5 into the pin hole. The fixing plate can rotate around the connection point, thereby driving the array antenna 1 connected to the fixing plate to pitch back and forth. A long rod 10 that can be extended and shortened is connected between the opposite left and right brackets 2. The long rod 10 limits the movement direction of the bracket 2, which can only move in the left and right direction. At the same time, a roller 9 is installed at the bottom of the bracket 2. The roller 9 allows the bracket 2 to move in the left and right direction, thereby changing the distance between the two brackets 2 to adapt to different diameters of the array antenna 1 and adjust the spacing between the two brackets 2.

[0021] Furthermore, in addition to the roller 9, a short column 11 is installed at the bottom of the support 2. The short column 11 is in contact with the ground to improve the stability of the device and prevent the support 2 from sliding or shaking.

[0022] In this embodiment, see Figure 3 and Figure 4For the fixing plate, the fixing plate includes an arc panel 4 and a frame A3 for connecting with the bracket 2. The frame A3 is an irregular convex frame structure. A positioning pin 5 is inserted into the center of the frame A3. The positioning pin 5 is inserted into the corresponding pin hole of the bracket 2 and the two are locked together, thereby connecting the fixing plate to the bracket 2. The fixing plate can rotate around the positioning point. The outer surface of the arc panel 4 is fixedly connected to the other end of the frame A3, and the inner arc surface of the arc panel 4 can fit into the circular end face of the array antenna 1. The arc panel 4 and the array antenna 1 are fixedly connected by a bolt inserted and locked together, thereby fixing the array antenna 1 to the fixing plate.

[0023] It should be noted that this solution uses bracket 2 and fixing plate to support and fix the area array antenna 1 from the side, avoiding the situation in the existing case where the support column would block the back of the area array antenna 1, which would make it inconvenient to install components.

[0024] In this embodiment, see Figure 5 and Figure 6 For the rotating mounting plate; the rotating mounting plate includes an L-shaped plate 8 and a slide rod 7. The L-shaped plate 8 is vertically connected by a side plate and a bottom plate, and the slide rod 7 is connected to the bottom plate. The side plate has a central hole and is aligned with the mounting hole at the edge of the array antenna 1. The two are connected by bolts. The slide rod 7 is adapted to be inserted into the arc groove 6 of the adjustment plate and slides along the arc track of the arc groove 6.

[0025] In this embodiment, see Figure 5 and Figure 7 For the adjustment plate; the adjustment plate is fixedly installed on the bracket 2 via frame B12. Frame B12 is a rectangular frame and the free end of frame B12 is connected to a rectangular plate. An arc-shaped groove 6 is opened on the rectangular plate for fitting and inserting the slide rod 7. When rotating the array antenna 1 back and forth, the slide rod 7 slides along the arc-shaped groove 6 of the adjustment plate. After adjusting to a suitable pitch angle, the end of the slide rod 7 at the position of the adjustment plate is locked. After the tilt angle of the array antenna 1 is fixed, the components can be easily installed on its back side.

[0026] This solution first determines the diameter of the circular array antenna 1 to be assembled, then adjusts the spacing between the left and right brackets 2. After installing the array antenna 1 and the fixing plate, the fixing plate and the brackets 2 are locked together using the positioning pins 5. Next, the rotating mounting plate is installed on the left and right sides of the lower part of the array antenna 1. At the same time, the sliding rod 7 in the rotating mounting plate is inserted into the arc-shaped groove 6. According to the assembly and fixing angle requirements, the elevation angle of the array antenna 1 is adjusted to the correct position. Finally, the rotating mounting plate and the adjusting plate are fixed and locked together, effectively adjusting the tilt angle of the array antenna 1. The structure is simple and easy to operate.

[0027] Compared to the traditional method of supporting and fixing the array antenna 1 by setting support columns or blocks at the bottom, which is prone to safety accidents due to unstable support when assembling and wiring the antenna on the front and back surfaces of the supported array antenna 1, this solution, through the cooperation of bracket 2 and fixing plate, rotating mounting plate and adjusting plate, not only achieves support and fixation of the circular array antenna 1, but also eliminates the need to avoid the installation of components (the fixing structure in this solution is installed on the side of the array antenna 1). At the same time, it can effectively adjust the pitch angle of the array antenna 1, thereby avoiding the need for hoisting when assembling components on the front and back of the array, improving the overall assembly efficiency, and can be adapted to the auxiliary assembly of array antennas 1 of different diameters.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
