Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna angle adjustment device. Background Technology

[0002] Currently, when adjusting the horizontal and vertical angles of the mounting brackets for large microwave antennas, friction and rotation between the rough surfaces of the structural components occur. Furthermore, the large weight of large microwave antennas further increases the friction between the structural components, resulting in a large thrust required for angle adjustment and making antenna angle adjustment difficult.

[0003] Meanwhile, current mounting bracket structures all rely on the displacement generated by the rotation and movement of a nut on a screw to push the corresponding structural components, with the thrust increasing slowly. When the thrust generated by the nut's movement is less than the static friction force in the horizontal or pitch direction of the antenna, the pointing angle of the antenna's central axis will not change. When the thrust generated by the nut's movement is equal to or greater than the static friction force in the horizontal or pitch direction of the antenna, the pointing angle of the antenna's central axis will change. When the antenna rotates, its friction force is dynamic friction, which is usually less than the static friction force. This can cause the antenna to suddenly rotate significantly at a certain moment during adjustment (when the adjustment angle is gradually increased until the thrust is equal to or greater than the static friction force). Since the main lobe width of large microwave antennas is usually extremely narrow and the angle adjustment is extremely sensitive, the problem of sudden and significant angle changes in the aforementioned mounting brackets makes it difficult for adjustment personnel to control the antenna angle, requiring a lot of time for repeated adjustments to find the required angle. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an antenna angle adjustment device that can reduce friction, improve adjustment sensitivity and installation and debugging efficiency when adjusting the horizontal and vertical angles of the antenna.

[0005] To achieve the above objectives, this application provides an antenna angle adjustment device, comprising: a first mounting frame, the first mounting frame including: a fixing member, an upper crossbar, a lower crossbar, two upper mounting arms, a pitch adjustment rod, and multiple rotating structures; the fixing member is disposed on a first mounting rod; the upper crossbar and the lower crossbar are both connected to the fixing member through the rotating structures; one end of each of the two upper mounting arms is connected to the upper crossbar; the other end of each of the two upper mounting arms is connected to the back ring of the antenna through the rotating structures; one end of the pitch adjustment rod is connected to the lower crossbar; and the other end of the pitch adjustment rod is connected to the back ring of the antenna through the rotating structures.

[0006] The second mounting bracket includes a first clamping member and a horizontal adjustment assembly. The first clamping member is disposed on the second support rod. One end of the horizontal adjustment assembly is connected to the first clamping member, and the other end of the horizontal adjustment assembly is connected to the back ring of the antenna.

[0007] An antenna angle adjustment device according to an embodiment of the present invention has at least the following beneficial effects: When it is necessary to adjust the pitch angle of the antenna, the pitch adjustment rod undergoes displacement relative to the lower crossbar under the action of an external force. Driven by the pitch adjustment rod, the antenna deflects around the two upper mounting arms connected to the upper crossbar to achieve the adjustment of the pitch angle; When it is necessary to adjust the horizontal angle of the antenna, the horizontal adjustment component undergoes displacement relative to the first clamping member under the action of an external force. Driven by the horizontal adjustment component, both the upper and lower crossbars in the first mounting frame deflect around the fixing member, and the antenna deflects along with the upper crossbar. The antenna deflects due to the deflection of the lower crossbar, thereby achieving horizontal angle adjustment. The other ends of the two upper mounting arms and the other end of the pitch adjustment rod are connected to the antenna back ring through a rotating structure. The upper and lower crossbars are also connected to the fixed parts through a rotating structure. The design of the rotating structure greatly reduces the friction of the antenna during angle adjustment. Therefore, the thrust required for the pitch adjustment rod and the horizontal adjustment component during angle adjustment is significantly reduced, making the antenna angle adjustment more sensitive and the installation and debugging efficiency higher. It can effectively overcome the problem of large thrust required for antenna angle adjustment and the defect of insufficient angle adjustment sensitivity.

[0027] Currently, when adjusting the horizontal and vertical angles of the mounting brackets for large microwave antennas, friction and rotation between the rough surfaces of the structural components occur. Furthermore, the large weight of large microwave antennas further increases the friction between the structural components, resulting in a large thrust required for angle adjustment and making antenna angle adjustment difficult.

[0028] Meanwhile, current mounting bracket structures all rely on the displacement generated by the rotation and movement of a nut on a screw to push the corresponding structural components, with the thrust increasing slowly. When the thrust generated by the nut's movement is less than the static friction force in the horizontal or pitch direction of the antenna, the pointing angle of the antenna's central axis will not change. When the thrust generated by the nut's movement is equal to or greater than the static friction force in the horizontal or pitch direction of the antenna, the pointing angle of the antenna's central axis will change. When the antenna rotates, its friction force is dynamic friction, which is usually less than the static friction force. This can cause the antenna to suddenly rotate significantly at a certain moment during adjustment (when the adjustment angle is gradually increased until the thrust is equal to or greater than the static friction force). Since the main lobe width of large microwave antennas is usually extremely narrow and the angle adjustment is extremely sensitive, the problem of sudden and significant angle changes in the aforementioned mounting brackets makes it difficult for adjustment personnel to control the antenna angle, requiring a lot of time for repeated adjustments to find the required angle.

[0029] Based on this, the present invention provides an antenna angle adjustment device that can reduce friction, improve adjustment sensitivity, and increase installation and debugging efficiency when adjusting the horizontal and vertical angles of the antenna.

[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] Reference Figure 1-5 This utility model provides an antenna angle adjustment device, including: a first mounting frame 1000, the first mounting frame 1000 including: a fixing member 1100, an upper crossbar 1200, a lower crossbar 1300, two upper mounting arms 1400, a pitch adjustment rod 1500 and multiple rotating structures 1600. The fixing member 1100 is disposed on the first mounting rod 1. The upper crossbar 1200 and the lower crossbar 1300 are both connected to the fixing member 1100 through the rotating structures 1600. One end of each of the two upper mounting arms 1400 is connected to the upper crossbar 1200, and the other end of each of the two upper mounting arms 1400 is connected to the back ring 140 of the antenna through the rotating structures 1600. One end of the pitch adjustment rod 1500 is connected to the lower crossbar 1300, and the other end of the pitch adjustment rod 1500 is connected to the back ring 140 of the antenna through the rotating structures 1600.

[0032] The second mounting bracket 2000 includes a first clamping member 2100 and a horizontal adjustment component 2200. The first clamping member 2100 is disposed on the second support rod 2. One end of the horizontal adjustment component 2200 is connected to the first clamping member 2100, and the other end of the horizontal adjustment component 2200 is connected to the back ring 140 of the antenna.

[0033] According to an embodiment of the present invention, when the pitch angle of the antenna needs to be adjusted, the pitch adjustment rod 1500 is displaced relative to the lower crossbar 1300 under the action of an external force. Driven by the pitch adjustment rod 1500, the antenna deflects around the two upper mounting arms 1400 connected to the upper crossbar 1200 to achieve the pitch angle adjustment. When the horizontal angle of the antenna needs to be adjusted, the horizontal adjustment component 2200 is displaced relative to the first clamping member 2100 under the action of an external force. Driven by the horizontal adjustment component 2200, both the upper crossbar 1200 and the lower crossbar 1300 in the first mounting bracket 1000 deflect around the fixing member 1100. The antenna deflects with the upper crossbar 1200 and the lower crossbar 1300. The deflection of rod 1300 allows for horizontal angle adjustment. The other ends of the two upper mounting arms 1400 and the elevation adjustment rod 1500 are connected to the antenna's back ring 140 via a rotating structure 1600. The upper crossbar 1200 and lower crossbar 1300 are connected to the fixing component 1100 via the rotating structure 1600. The design of the rotating structure 1600 significantly reduces the friction of the antenna during angle adjustment, thus significantly reducing the thrust required for the elevation adjustment rod 1500 and the horizontal adjustment component 2200 during angle adjustment. This makes the antenna angle adjustment more sensitive, improves installation and debugging efficiency, and effectively overcomes the problem of high thrust required for antenna angle adjustment and the lack of sensitivity in angle adjustment.

[0034] In some embodiments, refer to Figure 1 One end of the pitch adjustment rod 1500 is connected to the lower crossbar 1300 through two second adjustment nuts 10. When it is necessary to adjust the pitch angle of the antenna, the two second adjustment nuts 10 rotate under the action of external force, and the pitch adjustment rod 1500 is displaced relative to the lower crossbar 1300. Then, driven by the pitch adjustment rod 1500, the antenna deflects around the two upper mounting arms 1400 connected to the upper crossbar 1200 to achieve the adjustment of the pitch angle.

[0035] In some embodiments, refer to Figure 2 The rotating structure 1600 includes a planar thrust ball bearing 1610 and a bolt 1620. Holes are provided at the other end of the upper mounting arm 1400 and in the planar thrust ball bearing 1610. The bolt 1620 passes through the holes in the other end of the upper mounting arm 1400 and the planar thrust ball bearing 1610 and connects to the back ring 140 of the antenna.

[0036] Understandably, using the 1610 planar thrust ball bearing can effectively reduce the friction of the antenna during angle adjustment, improve adjustment sensitivity, and enhance installation and debugging efficiency.

[0037] In some embodiments, refer to Figure 1A second angle steel 110 is provided on the back ring 140 of the antenna. The rotating structure 1600 includes a planar thrust ball bearing 1610 and a bolt 1620. Holes are provided at the other end of the upper mounting arm 1400, in the planar thrust ball bearing 1610, and on the second angle steel 110. After the bolt 1620 passes through the holes in the second angle steel 110, the holes in the planar thrust ball bearing 1610, and the holes at the other end of the upper mounting arm 1400, it is fixed by installing a flat washer and a fastening nut 20.

[0038] Understandably, when it is necessary to adjust the antenna's elevation angle, the fastening nuts 20 used to fix the upper mounting arm 1400 and the second angle steel 110 should be loosened in advance.

[0039] In some embodiments, the rotating structure 1600 includes a planar thrust ball bearing 1610 and a bolt 1620. Holes are provided at the other end of the pitch adjustment rod 1500 and in the planar thrust ball bearing 1610. A third angle steel 120 is provided on the back ring 140 of the antenna, and holes are provided on the third angle steel 120. After the bolt 1620 passes through the holes at the other end of the pitch adjustment rod 1500, the holes in the planar thrust ball bearing 1610, and the holes on the third angle steel 120, it is fixed by installing a flat washer and a fastening nut 20.

[0040] Understandably, when it is necessary to adjust the pitch angle of the antenna, the fastening nut 20 used to fix the other end of the pitch adjustment rod 1500 to the third angle steel 120 should be loosened in advance.

[0041] In some embodiments, the fixing member 1100 includes a fixing channel steel 1110, a second clamping member 1120 and a third clamping member 1130. The fixing channel steel 1110 is fixed to the first clamping rod 1 through the second clamping member 1120 and the third clamping member 1130. The upper crossbar 1200 is connected to the second clamping member 1120 through a rotating structure 1600, and the lower crossbar 1300 is connected to the third clamping member 1130 through the rotating structure 1600.

[0042] In some embodiments, the second clamping member 1120 includes two first U-bolts 1121 and two fixing angle steels 1122. The two fixing angle steels 1122 are connected to the fixing channel steel 1110. The two first U-bolts 1121 are connected to the two fixing angle steels 1122. The first holding rod 1 is disposed between the two first U-bolts 1121 and the two fixing angle steels 1122.

[0043] In some embodiments, the second clamping member 1120 further includes a first transition angle steel 1123, which is connected to the fixed channel steel 1110, and the upper crossbar 1200 is connected to the first transition angle steel 1123 through a rotating structure 1600.

[0044] In some embodiments, the rotating structure 1600 includes a planar thrust ball bearing 1610 and a bolt 1620. Holes are provided in the upper crossbar 1200, the planar thrust ball bearing 1610, and the first transition angle steel 1123. After the bolt 1620 passes through the holes in the upper crossbar 1200, the planar thrust ball bearing 1610, and the first transition angle steel 1123, it is fixed by installing a flat washer and a fastening nut 20.

[0045] In some embodiments, the rotating structure 1600 includes a planar thrust ball bearing 1610 and a bolt 1620. Holes are provided in the lower crossbar 1300, the planar thrust ball bearing 1610, and the third clamping member 1130. After the bolt 1620 passes through the holes in the third clamping member 1130, the planar thrust ball bearing 1610, and the lower crossbar 1300, it is fixed by installing a flat washer and a fastening nut 20.

[0046] It is understandable that when the horizontal angle of the antenna needs to be adjusted, the fastening nuts 20 used to fix the upper crossbar 1200 and the first transition angle steel 1123 should be loosened in advance, as should the fastening nuts 20 used to fix the lower crossbar 1300 and the third clamping member 1130.

[0047] In some embodiments, the second clamping member 1120 and the third clamping member 1130 are identical in size and structure.

[0048] In some embodiments, the first mounting bracket 1000 further includes a support rod 1700, one end of which is connected to the upper crossbar 1200 and the other end of which is connected to the lower crossbar 1300.

[0049] Preferably, there are two support rods 1700. The two support rods 1700 are connected to the upper crossbar 1200 and the lower crossbar 1300 to form a square structure, which enables the first mounting bracket 1000 to support the antenna more stably. During the process of adjusting the antenna angle, it is not easy to shake, thus improving the accuracy of angle adjustment.

[0050] In some embodiments, refer to Figure 1-5 The horizontal adjustment assembly 2200 includes a horizontal pull rod 2210 and an adjustment member 2220. The adjustment member 2220 is connected to the first clamping member 2100. One end of the horizontal pull rod 2210 is sleeved on the adjustment member 2220 and the first clamping member 2100, and the other end of the horizontal pull rod 2210 is connected to the back ring 140 of the antenna.

[0051] It should be noted that an end angle steel 130 is provided on the back ring 140 of the antenna, and the other end of the horizontal tie rod 2210 is connected to the end angle steel 130 on the back ring 140 of the antenna through a fastening nut 20.

[0052] It is understandable that when it is necessary to adjust the horizontal angle or the pitch angle of the antenna, the fastening nut 20 used to fix the horizontal tie rod 2210 and the end angle steel 130 should be loosened in advance.

[0053] In some embodiments, refer to Figure 3-5 The adjusting component 2220 includes an adjusting rod 2221, a second U-bolt 2222, two first adjusting nuts 2223, and a first angle steel 2224. The second U-bolt 2222 is connected to the first angle steel 2224. A horizontal tie rod 2210 is disposed between the second U-bolt 2222 and the first angle steel 2224. One end of the adjusting rod 2221 is fixedly connected to the first clamping component 2100, and the other end of the adjusting rod 2221 is connected to the first angle steel 2224 through the two first adjusting nuts 2223.

[0054] It should be noted that the second U-bolt 1620 and the first angle steel 2224 are connected by two fastening nuts 20. The fastening nuts 20 can fix the horizontal tie rod 2210 between the second U-bolt 2222 and the first angle steel 2224.

[0055] Understandably, when it is necessary to adjust the antenna's elevation angle, the fastening nut 20 used to fix the horizontal tie rod 2210 between the second U-bolt 2222 and the first angle steel 2224 should be loosened in advance.

[0056] Understandably, when the horizontal angle of the antenna needs to be adjusted, the two first adjusting nuts 2223 rotate under the action of external force, causing the other end of the adjusting rod 2221 to shift relative to the first angle steel 2224. This causes the horizontal tie rod 2210 connected to the antenna back ring 140 to shift in the opposite direction to the adjusting rod 2221. Driven by the horizontal tie rod 2210, the upper crossbar 1200 and the lower crossbar 1300 in the first mounting bracket 1000 will both deflect around the fixing member 1100. The antenna adjusts its horizontal angle as the upper crossbar 1200 and the lower crossbar 1300 deflect.

[0057] In some embodiments, refer to Figure 3 The first clamping member 2100 includes a mounting channel steel 2110, a mounting clamping plate 2120, a connector 2130, and an annular hoop 2140. The mounting channel steel 2110 and the mounting clamping plate 2120 are respectively disposed on both sides of the second support rod 2. The mounting channel steel 2110 is connected to the mounting clamping plate 2120 by two bolts 1620. One end of the connector 2130 is connected to the mounting channel steel 2110, and the other end of the connector 2130 is connected to the annular hoop 2140. The annular hoop 2140 is used to fit the horizontal tie rod 2210.

[0058] It should be noted that three fastening nuts 20 are also provided on the outside of the annular hoop 2140. After the horizontal tie rod 2210 is sleeved on the annular hoop 2140, it is fixed inside the annular hoop 2140 by two fastening nuts 20. In addition, one end of the adjusting rod 2221 is connected to the annular hoop 2140 by a fastening nut 20.

[0059] It is understandable that when it is necessary to adjust the pitch angle or the horizontal angle of the antenna, the two fastening nuts 20 used to fix the horizontal tie rod 2210 in the ring hoop 2140 and the fastening nut 20 used to fix the adjusting rod 2221 in the ring hoop 2140 should be loosened in advance.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
