Description

Technical Field

[0001] This utility model relates to the field of antenna installation equipment technology, and in particular to an adjustment turntable for antenna installation. Background Technology

[0002] Transmitting or receiving antennas operating in the meter-wave, centimeter-wave, and millimeter-wave bands are collectively referred to as microwave antennas. Microwaves primarily propagate through space, and to increase communication distance, antennas are typically mounted relatively high. The traditional method of antenna installation involves directly mounting the antenna on top of a fixed support. This results in a fixed antenna orientation, making it impossible to adjust the antenna's direction according to requirements, which can easily lead to problems with poor signal transmission and reception.

[0003] Although existing technologies improve antenna adjustability by adding an adjustment gimbal, allowing the antenna orientation to be changed as needed, their adjustment precision is poor. They cannot accurately position the antenna tilt and precisely define the antenna orientation. This is because existing adjustment gimbals directly drive the antenna deflection through rotating drive devices such as motors. Conventional rotating drive devices have large deflection errors, and the antenna orientation accuracy is limited by the unit deflection amount of the rotating drive device, making it impossible to guarantee the accuracy of the deflection. The tilted antenna needs to be fixed in its attitude by the rotating drive device after the deflection is completed. However, the rotating drive device does not have an independent locking structure, and the positioning force it provides is insufficient to stably maintain the antenna's tilt attitude in severe weather conditions such as strong winds. This cannot guarantee the stability of the antenna orientation and is very likely to cause unstable signal transmission and reception. Utility Model Content

[0004] The purpose of this invention is to provide an antenna mounting adjustment turntable that can precisely adjust and position the tilt angle of the antenna to ensure the adjustment accuracy and stability of the antenna orientation. This solves the problems of existing adjustment gimbals that use motors to adjust the antenna orientation, which cannot guarantee the tilt accuracy of the antenna and cannot provide a high-strength limiting force for the tilted antenna, thus failing to guarantee the orientation stability of the tilted antenna.

[0005] The technical solution adopted by this utility model is as follows: an adjustable turntable for antenna installation, including a base mounted on a bracket, a turntable bearing centrally disposed on the base, a rotating cover that covers the base connected to the top of the turntable bearing, and a deflection drive unit capable of driving the rotating cover to rotate on the base; an inclined support mechanism capable of selectively constructing an inclined support plane is provided on the top surface of the rotating cover, and a quick-release insert frame capable of positioning the flat panel antenna is also installed on the inclined support plane defined by the inclined support mechanism.

[0006] According to a preferred embodiment, the tilting support mechanism includes a base plate, a support bar, a rotating connecting shaft, a telescopic positioning rod, and a support plate. The base plate is mounted on the top surface of the rotating cover, and the support bar and the telescopic positioning rod are aligned and arranged on the surface of the base plate away from the rotating cover. The upper edge of the support bar is connected to the support plate through the rotating connecting shaft. The lower axial end and the upper axial end of the telescopic positioning rod are respectively hinged to the top surface of the rotating cover and the bottom surface of the support plate, so that the support plate can tilt and deflect around the rotating connecting shaft when the telescopic positioning rod extends or retracts.

[0007] According to a preferred embodiment, an angle measuring scale plate capable of characterizing the tilt angle of the support plate is supported on the side of the support bar by a support bar rod; an auxiliary support block is also provided on the top surface of the support bar.

[0008] According to a preferred embodiment, the outer ring of the turntable bearing is connected to the top surface of the base, and an inner ring is coaxially inserted into the outer ring, with the inner ring extending out of the top surface of the outer ring and connected to the top surface of the inner body of the rotating cover.

[0009] According to a preferred embodiment, a transmission internal gear ring and a shielding washer capable of filling the assembly gap are further provided on the inner side wall of the rotating cover.

[0010] According to a preferred embodiment, a transmission gear capable of meshing with the transmission internal gear ring is sleeved on the vertical rotation shaft of the deflection drive unit.

[0011] According to a preferred embodiment, the quick-release insert frame includes a lower half frame and an upper half frame that can be assembled together to form a limiting installation frame, and a U-shaped connecting groove plate that can be snapped onto the lower half frame is arranged at the lower edge of the upper half frame; the lower half frame is mounted on the support plate with its opening facing upward.

[0012] According to a preferred embodiment, a first slot is provided on the inner wall surface of the lower half frame, and a second slot is provided on the inner wall surface of the upper half frame.

[0013] According to a preferred embodiment, an installation slot is provided on the outer side wall of the lower half frame, and a limiting post is movably inserted into the installation slot. The limiting post is connected to the bottom surface of the slot cavity of the installation slot by an elastic limiting spring. An inclined auxiliary support rod is also provided on the outer side wall of the lower half frame, and the lower end of the inclined auxiliary support rod is detachably connected to the support plate.

[0014] According to a preferred embodiment, a positioning through hole adapted to the limiting post is provided on the plate body of the U-shaped connecting groove plate.

[0015] The beneficial effects of this utility model are:

[0016] The rotating cover and deflection drive unit provided in this application can work together to rotate the flat panel antenna around its vertical axis, enabling the antenna to transmit and receive signals from different directions in a directly facing manner. Furthermore, the large transmission ratio between the two components reduces the unit rotation amount and improves rotational accuracy. The tilt support mechanism provided in this application allows for controllable adjustment of the flat panel antenna's tilt angle through a high-precision telescopic rod, while providing highly stable support. Compared to the method of limiting the tilt angle using a motor deflection, the telescopic rod offers stronger positioning capabilities and more precise adjustment control, enabling the flat panel antenna to achieve higher precision tilt attitude limitation and ensuring its stability when operating in high-altitude environments. The quick-release mounting frame provided in this application enables rapid assembly and disassembly of the flat panel antenna and provides protection, improving the stability and convenience of antenna clamping.

Obviously, the following description of the structure of the drawings is only some embodiments of this utility model.

[0024] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, under reasonable circumstances (without self-contradiction), include both direct and indirect connections (linkages).

[0025] The following is a detailed explanation with reference to the accompanying drawings.

[0026] Example 1

[0027] This application provides an adjustment turntable for antenna mounting, which includes a base 1, a turntable bearing 2, a rotating cover 3, a deflection drive unit 4, a tilt support mechanism 5, and a quick-release insert frame 6.

[0028] according to Figure 1-4 In one specific embodiment, a base 1 is mounted on a support frame such as a triangular bracket or steel frame via bolts or welding. A turntable bearing 2 is centrally mounted on the base 1. A rotating cover 3, which is attached to the top of the turntable bearing 2, is also connected to the base 1. A deflection drive unit 4, capable of driving the rotating cover 3 to rotate, is also provided on the base 1. An inclined support mechanism 5, capable of selectively constructing an inclined support plane, is provided on the top surface of the rotating cover 3. A quick-release insert frame 6, capable of positioning the flat panel antenna, is also installed on the inclined support plane defined by the inclined support mechanism 5. The rotating cover 3 and the deflection drive unit 4 provided in this application can cooperate to realize the rotation of the flat panel antenna around its vertical axis, thereby enabling the flat panel antenna to transmit and receive signals in different directions in a directly facing manner. Furthermore, the two have a large transmission ratio, reducing the unit rotation amount and improving the rotation accuracy. The tilt support mechanism 5 provided in this application can controllably adjust the tilt angle of the flat panel antenna through high-precision telescopic extension of the rod, while providing highly stable support. Compared with the method of limiting the tilt angle by motor deflection, the telescopic rod has stronger positioning capabilities and more precise adjustment control, enabling the flat panel antenna to achieve higher precision tilt attitude limitation and ensuring its stability when working in high-altitude environments. The quick-release insertion frame 6 provided in this application enables quick assembly and disassembly of the flat panel antenna and provides protection, improving the stability and convenience of flat panel antenna clamping.

[0029] Preferably, the outer ring rotating body 21 of the turntable bearing 2 is connected to the top surface of the base 1. Preferably, an inner ring rotating body 22 is coaxially inserted inside the outer ring rotating body 21. More preferably, the inner ring rotating body 22 extends beyond the top surface of the outer ring rotating body 21 and connects to the top surface of the inner body of the rotating cover 3. Specifically, the inner ring rotating body 22, centrally mounted on the rotating cover 3, can rotate about its axis relative to the outer ring rotating body 21, so that the rotating cover 3 can rotate with the inner ring rotating body 22, thereby realizing the coaxial rotation of the rotating cover 3 relative to the base 1, which changes the direction of the inclined support plane constructed by the inclined support mechanism 5. Specifically, the turntable bearing 2 is a conventional existing product, and this application can use a turntable bearing body of model PRE90C.

[0030] Preferably, a transmission internal gear ring 31 and a shielding washer 32 capable of filling the assembly gap are also provided on the inner side wall of the annular body of the rotating cover 3. Specifically, the transmission internal gear ring 31 is located above the horizontal plane defined by the top surface of the base 1, thereby facilitating meshing and transmission with the deflection drive unit 4; the shielding washer 32 is located below the horizontal plane defined by the top surface of the base 1, so that when the rotating cover 3 is fastened on the base 1, the shielding washer 32 can fill the assembly gap between the rotating cover 3 and the base 1, so that the rotating cover 3 and the base 1 cooperate to form an installation chamber that is effectively separated from the outside, reducing the possibility of corrosion damage to the deflection drive unit 4 and the turntable bearing 2, and improving the service life of both.

[0031] Preferably, a transmission gear 41 capable of meshing with the transmission internal gear ring 31 is sleeved on the vertical rotation axis of the deflection drive unit 4. Specifically, the deflection drive unit 4 is a stepper motor capable of outputting small-angle deflection torque, and an AWFPD-64X stepper motor can be selected. Preferably, the deflection drive unit 4 provided in this application is mounted on the platform 1 with its rotation axis perpendicular to the top surface of the platform 1, and a transmission gear 41 capable of rotating with the rotation axis is sleeved on the upper axial end of the rotation axis of the deflection drive unit 4. The transmission gear 41 has a rotation radius much smaller than that of the transmission internal gear ring 31, thereby forming a sufficiently small transmission ratio between the transmission gear 41 and the internal gear ring 31. As a result, the transmission gear 41 can limit the rotation unit amount of the transmission internal gear ring 31 to a smaller value, effectively improving the rotational accuracy of the transmission internal gear ring 31 and the rotating cover 3.

[0032] Preferably, the tilting support mechanism 5 includes a base plate 51, a support bar 52, a rotating connecting shaft 53, a telescopic positioning rod 54, and a support plate 55. Preferably, the base plate 51 is mounted on the top surface of the rotating cover 3. More preferably, the support bar 52 and the telescopic positioning rod 54 are aligned and arranged on the surface of the base plate 51 away from the rotating cover 3. Preferably, the upper edge of the support bar 52 is connected to the support plate 55 via the rotating connecting shaft 53. Preferably, the lower axial end and the upper axial end of the telescopic positioning rod 54 are hinged to the top surface of the rotating cover 3 and the bottom surface of the support plate 55, respectively, so that the support plate 55 can tilt and deflect around the rotating connecting shaft 53 when the telescopic positioning rod 54 extends or retracts in length. Specifically, the telescopic positioning rod 54 can be a high-precision electro-hydraulic rod of model AWTPF-42-CB, which can extend and retract as needed, allowing the rod of varying length to stably support the support plate 55. Thus, while cooperating with the support bar 52 to ensure the stability of the support plate 55, the telescopic positioning rod 54 can also precisely change the tilt angle of the support plate 55, forming an adjustable and structurally stable tilted support plane. This effectively changes the orientation of the flat panel antenna placed within the quick-release mounting frame 6, improving the stability of the flat panel antenna during tilted placement and the stability of its tilted orientation. The rotating connecting shaft 53 provided in this application, when connecting the support bar 52 to the support plate 55, can cooperate with the support bar 52 to provide rotational support for the support plate 55, ensuring the stability of the support plate 55's positioning.

[0033] Preferably, an angle measuring scale plate 522 capable of characterizing the tilt angle of the support plate 55 is supported on the side of the support bar 52 by a support bar rod 521. Preferably, an auxiliary support block 523 is also provided on the top surface of the support bar 52. The angle measuring scale plate 522 provided in this application is a transparent angle plate, and its plate body is marked with angle graduations, so that it can characterize the tilt angle of the support plate 55. The auxiliary support block 523 provided in this application can provide auxiliary support when the support plate 55 is flat, thereby reducing the support stress on the rotating connecting shaft 53 and improving its service life.

[0034] Preferably, the quick-release mounting frame 6 includes a lower half-frame 61 and an upper half-frame 62 that can be assembled together to form a limiting mounting frame. More preferably, a U-shaped connecting slot plate 63 is provided at the lower edge of the upper half-frame 62 to fit onto the lower half-frame 61. Preferably, the lower half-frame 61 is mounted on the support plate 55 with its opening facing upwards. The lower half-frame 61 and upper half-frame 62 provided in this application cooperate to form a ring-shaped limiting frame, thereby effectively limiting the assembly position of the flat panel antenna. This effectively limits the working position of the flat panel antenna when it is tilted, and the closed-loop frame can form a protective skirt, thereby improving the protection effect of the flat panel antenna and preventing foreign objects from hitting the edge and damaging the flat panel antenna. The U-shaped connecting slot plate 63 provided in this application can realize the quick assembly and connection of the lower half-frame 61 and the upper half-frame 62, thereby facilitating the quick assembly and disassembly of the flat panel antenna, reducing the difficulty and time consumption of assembly and disassembly, facilitating quick assembly and disassembly in high-altitude environments, improving assembly and disassembly efficiency, and reducing assembly and disassembly risks.

[0035] Preferably, a first slot 611 is formed on the inner wall of the lower half-frame 61. Preferably, a second slot 621 is also formed on the inner wall of the upper half-frame 62. More preferably, silicone filling pads are provided in the cavities of both the first slot 611 and the second slot 621. Preferably, an installation slot 612 is formed on the outer wall of the lower half-frame 61. Preferably, a limiting post 613 is movably inserted into the installation slot 612. Specifically, the limiting post 613 is connected to the bottom surface of the cavity of the installation slot 612 by an elastic limiting spring 614. Preferably, an inclined auxiliary support rod 615 is also provided on the outer wall of the lower half-frame 61. The lower end of the inclined auxiliary support rod 615 is detachably connected to the support plate 55. Preferably, a positioning through hole 631 adapted to the limiting post 613 is formed on the plate of the U-shaped connecting slot plate 63. The limiting post 613 provided in this application can extend out of the mounting slot 612 under the drive of the elastic limiting spring 614. Thus, the limiting post 613 positions the U-shaped connecting slot plate 63 on the lower half frame 61 by inserting it into the positioning through hole 631, thereby realizing the quick assembly connection of the lower half frame 61 and the upper half frame 62.

[0036] Preferably, the electrical components such as the deflection drive unit 4 and the telescopic positioning rod 54 are electrically connected to the controller and the power supply. The control method of this application is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0037] The working principle of this application is as follows:

[0038] During the installation of the flat panel antenna, insert the antenna through the opening in the lower half-frame 61, then secure the upper half-frame 62 onto the plate outside the lower half-frame 61. Simultaneously, secure the U-shaped connecting slot plate 63 to the outer sides of the lower half-frame 61. Manually press the limiting post 613 to press it into the mounting slot 612, thereby releasing the obstruction of the U-shaped connecting slot plate 63. The U-shaped connecting slot plate 63 then descends further, allowing the lower half-frame 61 and upper half-frame 62 to be relatively grounded, thus limiting the position of the flat panel antenna. At this point, the limiting post 613, pushed by the elastic limiting spring 614, can insert into the positioning through hole 631, effectively limiting the position of the U-shaped connecting slot plate 63 on the lower half-frame 61. When disassembling the frame structure is required, press the limiting post 613 back into the mounting slot 612, and then disassemble the frame by lifting the upper half-frame 62.

[0039] When it is necessary to adjust the orientation of the flat panel antenna, the telescopic positioning rod 54 can change its length by telescopic movement, thereby changing the tilt angle of the flat panel antenna. The deflection drive unit 4 can drive the rotating cover 3 to rotate, thereby changing the tilt direction of the flat panel antenna, so as to realize the signal transmission and reception of the flat panel antenna in different directions and at different tilt angles.
