Description

Technical Field

[0001] This utility model relates to the technical field of satellite antenna reflector assembly equipment, and in particular to a support device for a satellite antenna reflector. Background Technology

[0002] Satellite antennas are primarily used to reflect satellite signals to the feedhorn and LNB located at the focal point, collecting weak signals from the satellite while minimizing noise. Their reflectors are typically parabolic. After reflection by the parabolic antenna reflector, the satellite signal is concentrated at its focal point. Some satellite antenna reflectors can have diameters of several meters. During production, these reflectors are assembled using a single, integrated mold. Typically, a parabolic mold is supported by fiberglass. This mold is used to correct the solid parabolic surface of the satellite antenna reflector during molding. However, this large fiberglass correction mold occupies a lot of space, is difficult to transport, and is prone to deformation after molding, leading to decreased calibration accuracy. Improvements are urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a support device for a satellite antenna reflector, which has the effect of adjustable height and fitting angle of the support component, improving the positioning and support performance of the satellite antenna reflector.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a support device for a satellite antenna reflector, comprising a lifting mechanism and an adaptive adjustment support device, wherein the adaptive adjustment support device comprises a support plate, a mounting frame and an adjustable support assembly, the support plate is disposed at the output end of the lifting mechanism, the mounting frame is disposed on the support plate, and the adjustable support assembly comprises a swing connector and a support member fixed on the swing connector for fixing and supporting the antenna reflector, wherein the support member is rotatably connected to the mounting frame through the swing connector.

[0005] By adopting the above technical solution, multiple support devices can be arranged at the bottom of the satellite antenna reflector. A lifting mechanism can be used to drive the adaptive adjustment support devices at corresponding positions to rise and fall, ensuring that the adaptive adjustment support devices are positioned and supported against the bottom surface of the satellite antenna reflector at their respective locations. At this time, the support components of the adjustable support assembly contact the bottom surface of the satellite antenna reflector. Since the curvature of each satellite antenna reflector's bottom surface is different, the support components at different positions drive the swing connector to adaptively rotate relative to the mounting frame to a predetermined position, ensuring that each support component can be tightly fitted against the corresponding position on the bottom surface of the satellite antenna reflector. The support height is adjustable, and the support components can adaptively rotate and fit with the curvature of the bottom surface of the satellite antenna reflector, thereby improving the support for the satellite antenna reflector and achieving better calibration results. This invention offers the advantages of adjustable support component height and fitting angle, improved positioning and support performance for the satellite antenna reflector.

[0006] A further feature of this invention is that the mounting bracket has a U-shaped structure and a mounting groove, one end of the swing connector is rotatably connected to the mounting groove via a rotating shaft, and the swing connector avoids or cooperates with the mounting groove in the rotation direction.

[0007] By adopting the above technical solution, the swing connector is rotatably connected in the mounting groove and can swing in the mounting groove with the rotating shaft as the rotation center, thereby adjusting the support angle between the support component and the satellite antenna reflector.

[0008] A further feature of this invention is that the outer wall of the swing connector is provided with an angle scale centered on the pivot axis, and the mounting bracket is provided with a pointer mark for indicating the value of the angle scale.

[0009] By adopting the above technical solution, when the swing connector rotates relative to the mounting bracket to a predetermined angle, the pointer mark points to the corresponding angle scale position, making it easy to clearly observe the rotation angle of the swing connector.

[0010] A further feature of this invention is that the supporting member includes a supporting connector and a keypad for fixing and connecting the antenna reflector.

[0011] A further feature of this invention is that a force sensor is connected between the mounting bracket and the support plate.

[0012] By adopting the above technical solution, the force sensor can monitor the downward pressure at the corresponding position of the satellite antenna reflector in real time, preventing local stress concentration on the satellite antenna reflector.

[0013] A further feature of this invention is that the lifting mechanism includes a lifting drive device and a floating support device, the floating support device is fixedly mounted on the output end of the lifting drive device, and the support plate is fixedly mounted on the floating support device.

[0014] By adopting the above technical solution, the lifting drive device is used to drive the floating support device to drive the adaptive adjustment support device to lift and adjust, so as to find the most suitable support height position. The floating support device can buffer the compressive stress generated by the adaptive adjustment support device, and prevent the device from making hard contact with the satellite antenna reflector, which would damage the surface of the satellite antenna reflector.

[0015] A further feature of this invention is that the lifting drive device includes a lifting drive component and a lifting seat assembly, wherein the lifting drive component is a hydraulic cylinder or a pneumatic cylinder, and the lifting seat assembly is fixed to the end of the piston rod of the hydraulic cylinder or the pneumatic cylinder.

[0016] By adopting the above technical solution, the lifting drive component can drive the lifting seat assembly to adjust the floating support device in height.

[0017] A further feature of this invention is that: a fixed seat is fixedly provided on the lifting drive component, a plurality of optical axes are provided parallel to each other at the bottom of the lifting seat assembly, a plurality of first linear bearings are provided on the fixed seat, and the optical axes are guided through the corresponding first linear bearings.

[0018] By adopting the above technical solution, it is beneficial to improve the consistency of the lifting adjustment direction of the lifting seat assembly.

[0019] A further configuration of this utility model is as follows: the floating support device includes a guide shaft, an elastic element, and a second linear bearing. The second linear bearing is fixedly mounted on the support plate, the guide shaft is fixedly mounted on the lifting seat assembly, the guide shaft is guided through the second linear bearing, the elastic element is sleeved on the guide shaft, and one end of the elastic element elastically abuts against the support plate, while the other end of the elastic element elastically abuts against the lifting seat assembly.

[0020] By adopting the above technical solution, the compressive stress generated by the satellite antenna reflector supports the plate by pressing down on the elastic element, which contracts and accumulates elastic potential energy. The guiding fit between the guide shaft and the second linear bearing can improve the consistency of the vertical movement of the support plate. At the same time, it ensures that the deformation direction of the elastic element is always along the axial direction of the guide shaft, preventing the elastic element from shifting laterally during elastic deformation, which could lead to fit failure. This extends the service life of the present invention and improves the operational stability of the equipment.

[0021] A further feature of this invention is that a stud is fixedly provided on the lifting seat assembly, a through hole is provided on the support plate corresponding to the stud, one end of the stud passes through the through hole and is locked by a locking nut, and the support plate is anti-detached from the stud by the locking nut.

[0022] By adopting the above technical solution, after the satellite antenna reflector is separated from the support device, the locking action of the locking nut and stud can effectively prevent the elastic element from pushing the support plate upward and separating it from the stud. In addition, the locking nut can also limit the floating distance between the support plate and the lifting seat assembly.

[0023] In summary, this utility model has the following beneficial effects:

[0024] A support plate is installed at the output end of the lifting mechanism, and a mounting frame is then mounted on the support plate. Support components are rotatably connected to the mounting frame via swing connectors. In use, multiple support devices can be arranged at the bottom of the satellite antenna reflector. The lifting mechanism drives the corresponding adaptive adjustment support devices to rise and fall, ensuring that each adaptive adjustment support device is positioned and supported against the bottom surface of the satellite antenna reflector. At this point, the support components of the adjustable support assembly contact the bottom surface of the satellite antenna reflector. Since the curvature of each satellite antenna reflector's bottom surface is different, the support components at different positions drive the swing connectors to adaptively rotate relative to the mounting frame to a predetermined position, ensuring that each support component can tightly fit against the corresponding position on the bottom surface of the satellite antenna reflector. The support height is adjustable, and the support components can adaptively rotate and fit with the curvature of the satellite antenna reflector's bottom surface, thereby improving the support for the satellite antenna reflector and resulting in better calibration. This invention offers the advantages of adjustable support component height and fitting angle, improved positioning and support performance for the satellite antenna reflector.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] A support device for a satellite antenna reflector, such as Figures 1-3 As shown, the device includes a lifting mechanism 1 and an adaptive adjustment support device 4. The adaptive adjustment support device 4 includes a support plate 5, a mounting frame 6, and an adjustable support assembly 7. The support plate 5 is located at the output end of the lifting mechanism 1, and the mounting frame 6 is located on the support plate 5. The adjustable support assembly 7 includes a swing connector 71 and a support member 72 fixed to the swing connector 71 for fixing and supporting the antenna reflector. The support member 72 is rotatably connected to the mounting frame 6 through the swing connector 71. The support member 72 includes a support connector 722 and a keypad 7 for fixing and connecting the antenna reflector. 23. Additionally, the adjustable support assembly 7 also includes a counterweight plate 721. When the satellite antenna reflector is not installed on the support component 72, the counterweight plate 72 can be used to simulate the downward pressure generated by the satellite antenna reflector on the support device, which facilitates assembly. When supporting the satellite antenna reflector later, the counterweight plate 72 can be removed or retained as a load-bearing component. A force sensor 8 is connected between the mounting bracket 6 and the support plate 5. The force sensor 8 can monitor the downward pressure at the corresponding position of the satellite antenna reflector in real time to prevent local stress concentration on the satellite antenna reflector.

[0033] like Figures 2-4As shown, the mounting bracket 6 has a U-shaped structure and a mounting groove 61. One end of the swing connector 71 is rotatably connected to the mounting groove 61 via a rotating shaft 62. The swing connector 71 avoids the mounting groove 61 in the rotation direction, allowing it to rotatably connect to the mounting groove 61 and swing about the rotating shaft 62 within the mounting groove 61, thereby adjusting the support angle between the support member 72 and the satellite antenna reflector. The outer wall of the swing connector 71 is provided with an angle scale 711 centered on the rotating shaft 62, and the mounting bracket 6 is provided with a scale for indicating the angle. The pointer mark 63 of the scale 711 points to the corresponding angle scale 711 position when the swing connector 71 rotates relative to the mounting bracket 6 to a predetermined angle, making it easy to clearly observe the rotation angle of the swing connector 71. In some other embodiments, an arc-shaped groove 64 can be opened on the mounting bracket 6 with the rotating shaft 62 as the rotation center, and a threaded hole 712 can be opened on the side wall of the swing connector 71. The bolt 713 passes through the arc-shaped groove 64 and is threaded into the corresponding threaded hole 712 to achieve locking and positioning between the swing connector 71 and the mounting bracket 6.

[0034] like Figures 1-4As shown, the lifting mechanism 1 includes a lifting drive device 2 and a floating support device 3. The floating support device 3 is fixed to the output end of the lifting drive device 2, and the support plate 5 is fixed to the floating support device 3. The lifting drive device 2 drives the floating support device 3 to move the adaptive adjustment support device 4 up and down to find the most suitable support height position. The floating support device 3 can buffer the compressive stress generated by the adaptive adjustment support device 4 to prevent the device from making hard contact with the satellite antenna reflector and causing damage to the surface of the satellite antenna reflector 4. The lifting drive device 2 includes a lifting drive component 21 and a lifting seat assembly 22. The lifting drive component 21 is a hydraulic cylinder or a pneumatic cylinder, and the lifting seat assembly 22 is fixed to the output end of the lifting drive device 2. At the piston rod end of the hydraulic cylinder or pneumatic cylinder, the lifting drive 21 can drive the lifting seat assembly 22 to adjust the floating support device 3 in height. In this embodiment, the lifting seat assembly 22 includes a lifting plate 221, a first adjusting plate 222 slidably disposed on the lifting plate 221, and a second adjusting plate 223 slidably disposed on the first adjusting plate 222. A first bolt 713 locking structure is provided between the first adjusting plate 222 and the lifting plate 221. The first bolt 713 locking structure is used to adjust the relative position of the first adjusting plate 222 relative to the lifting plate 221 in a first direction. A second bolt 713 locking structure is provided between the second adjusting plate 223 and the first adjusting plate 222. The structure is used to adjust the relative position of the second adjusting plate 223 with respect to the first adjusting plate 222 along a second direction, wherein the extension direction of the first direction is perpendicular to the extension direction of the second direction; a fixed seat 211 is fixedly provided on the lifting drive component 21, and a plurality of optical shafts 225 are provided parallel to each other at the bottom of the lifting seat assembly 22. A plurality of first linear bearings 212 are provided on the fixed seat 211, and the optical shafts 225 are guided through the corresponding first linear bearings 212, which helps to improve the consistency of the lifting adjustment direction of the lifting seat assembly 22; the floating support device 3 includes a guide shaft 31, an elastic element 32, and a second linear bearing 33. The second linear bearing 33 is fixedly provided on the support plate 5, and the guide shaft 31 is fixedly provided on the lifting seat assembly 22. The guide shaft 31 is guided through the second linear bearing 33. The elastic element 32 is sleeved on the guide shaft 31, with one end of the elastic element 32 elastically abutting against the support plate 5 and the other end of the elastic element 32 elastically abutting against the lifting seat assembly 22. The compressive stress generated by the satellite antenna reflector causes the support plate 5 to press down on the elastic element 32, causing it to contract and accumulate elastic potential energy. The guiding fit between the guide shaft 31 and the second linear bearing 33 can improve the consistency of the vertical movement of the support plate 5, while ensuring that the deformation direction of the elastic element 32 is always along the axial direction of the guide shaft 31. This prevents the elastic element 32 from shifting laterally during elastic deformation, which could lead to fit failure. This effectively extends the service life of the present invention and improves the operational stability of the equipment.A stud 226 is fixedly mounted on the lifting seat assembly 22. A through hole 51 is provided on the support plate 5 corresponding to the stud 226. One end of the stud 226 passes through the through hole 51 and is locked by a locking nut 227. The support plate 5 is secured to the stud 226 by the locking nut 227 to prevent detachment. When the satellite antenna reflector separates from the support device, the locking action of the locking nut 227 and the stud 226 effectively prevents the elastic element 32 from pushing the support plate 5 upwards and separating it from the stud 226. Additionally, the locking nut 227 also limits the floating distance between the support plate 5 and the lifting seat assembly 22.

[0035] In other embodiments, such as Figure 5 As shown, the lifting seat assembly 22 has an extension 224, which is used to increase the support height of the support device in cases where the distance from the ground is large.

[0036] The basic working principle of this utility model is as follows: A support plate 5 is set at the output end of the lifting mechanism 1, and then a mounting frame 6 is set on the support plate 5. The mounting frame 6 is rotatably connected to the support member 72 through the swing connector 71. In use, multiple support devices can be arranged at the bottom of the satellite antenna reflector. The lifting mechanism 1 can drive the adaptive adjustment support device 4 at the corresponding position to adjust its height, so that the adaptive adjustment support device 4 can be supported and positioned with the bottom surface of the satellite antenna reflector at the corresponding position. At this time, the support member 72 of the adjustable support assembly 7 is in contact with the bottom surface of the satellite antenna reflector. Because the curvature of the bottom surface of each satellite antenna reflector is different, the support members 72 at different positions drive the swing connector 71 to adaptively rotate relative to the mounting frame 6 to a predetermined position, ensuring that each support member 72 can be tightly fitted with the corresponding position of the bottom surface of the satellite antenna reflector. The support height is adjustable, and the support member 72 can adaptively rotate and fit with the curvature of the bottom surface of the satellite antenna reflector, thereby improving the support of the satellite antenna reflector of this utility model, resulting in better calibration effect. It has the effects of adjustable height and fitting angle of support member, and improved positioning and support performance of satellite antenna reflector.

[0037] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
