[0043] See Figure 1 , Figure 1The diagram shows a structural schematic of a base station antenna mounting and adjusting device according to some embodiments of this application. The base station antenna mounting and adjusting device 100 provided in this application includes a fixed mounting assembly 1, a lifting mechanism 2, a deflection mechanism 3, and a tilting mechanism 4. The lifting mechanism 2 is disposed on the fixed mounting assembly 1 and includes a lifting mounting component 21 and a lifting drive component 22. The lifting mounting component 21 is connected to the lifting drive component 22, and the lifting drive component 22 is configured to drive the lifting mounting component 21 to move along the lifting direction Z. The deflection mechanism 3 is disposed on the lifting mounting component 21 and includes a deflection mounting component 4. The device includes a mounting component 31 and a deflection drive component 32. The deflection mounting component 31 is connected to the deflection drive component 32. The deflection drive component 32 is configured to drive the deflection mounting component 31 to rotate around the deflection axis O1. The deflection axis O1 extends along the lifting direction Z. The tilt mechanism 4 is disposed on the deflection mounting component 31. The tilt mechanism 4 includes an antenna mounting component 41 and a pitch drive component 42. The antenna mounting component 41 is used to rotatably mount the base station antenna 200 on the deflection mounting component 31. The pitch drive component 42 is configured to drive the base station antenna 200 to rotate, and the rotation axis of the base station antenna 200 is perpendicular to the deflection axis O1.

[0044] like Figures 1 to 5 As shown in the diagram, the Z direction is the direction of ascent and descent.

[0045] The base station antenna mounting and adjustment device 100 is used to install the base station antenna 200 to the communication base station, and to adjust the height, azimuth and tilt of the base station antenna 200.

[0046] The height of base station antenna 200 refers to the distance from base station antenna 200 to the horizontal plane. The azimuth angle of base station antenna 200 refers to the angle of deflection of the maximum radiation direction of base station antenna 200 around an axis perpendicular to the horizontal plane; for example, using the maximum radiation direction of base station antenna 200 pointing due north as a standard, adjusting the maximum radiation direction of base station antenna 200 by an angle slightly east or west is the azimuth angle of base station antenna 200. That is, the azimuth angle when the maximum radiation direction of base station antenna 200 points due north is 0°. The tilt angle of base station antenna 200 refers to the angle between the maximum radiation direction of base station antenna 200 and the horizontal plane; for example, the tilt angle when the maximum radiation direction of base station antenna 200 is parallel to the horizontal plane is 0°.

[0047] By adjusting the height, azimuth, and tilt angle of the base station antenna 200, the signal of the adjusted base station antenna 200 can be made more stable and the coverage effect can be better.

[0048] During installation, the base station antenna 200 is mounted on the tilting mechanism 4, which is mounted on the deflection mounting part 31 of the deflection mechanism 3. The deflection mechanism 3 is mounted on the lifting mounting part 21 of the lifting mechanism 2, which is mounted on the fixed mounting assembly 1. This allows the base station antenna 200 to be mounted on the base station antenna mounting adjustment device 100. The fixed mounting assembly 1 serves as the mounting base for the base station antenna mounting adjustment device 100, used to fix the entire device to a high position such as the tower or pole of the communication base station. The fixed mounting assembly 1 allows adjustment of the mounting posture of the base station antenna mounting adjustment device 100, ensuring that the lifting direction Z is approximately perpendicular to the horizontal plane. This improves the adjustment effect on the height, azimuth, and tilt angle of the base station antenna 200.

[0049] The lifting mounting component 21 can move up and down along the lifting direction Z under the drive of the lifting drive component 22, thereby driving the deflection mechanism 3 and tilt mechanism 4, which are mounted on the lifting mounting component 21, and the base station antenna 200 to move up and down along the lifting direction Z, thus adjusting the height of the base station antenna 200. The lifting drive component 22 is the drive source, used to provide driving force for the lifting movement of the lifting mounting component 21. Since the lifting mounting component 21 is driven by the lifting drive component 22, the action of the lifting drive component 22 can be controlled by the electronic control program, which is beneficial to achieve linear adjustment of the height of the base station antenna 200. In addition, the data of the height adjustment of the base station antenna 200 can be recorded by software, and the performance parameters of the base station antenna 200 can be monitored simultaneously during the adjustment process, which is beneficial to adjusting the base station antenna 200 to the optimal state; the data recording of the adjustment process is complete and clear, which is convenient for management.

[0050] The deflection mounting component 31 can rotate around the deflection axis O1 under the drive of the deflection drive component 32, thereby driving the tilt mechanism 4 and the base station antenna 200, both mounted on the deflection mounting component 31, to rotate around the deflection axis O1, thus adjusting the azimuth angle of the base station antenna 200. The deflection drive component 32 also serves as a drive source, providing driving force for the deflection movement of the deflection mounting component 31. Since the deflection drive component 32 drives the deflection mounting component 31 to rotate around the deflection axis O1, the action of the deflection drive component 32 can be controlled by an electronic control program, which is beneficial for achieving linear adjustment of the azimuth angle of the base station antenna 200. Furthermore, the azimuth angle adjustment data of the base station antenna 200 can be recorded by software. During the adjustment process, the performance parameters of the base station antenna 200 can be monitored simultaneously, which is beneficial for adjusting the base station antenna 200 to its optimal state. The data recording during the adjustment process is complete and clear, facilitating management.

[0051] The base station antenna 200 is rotatably mounted on the deflection mounting component 31 via the antenna mounting component 41. The rotation axis of the base station antenna 200 is perpendicular to the deflection axis O1, meaning the rotation axis of the base station antenna 200 is approximately parallel to the horizontal plane. The pitch drive component 42 can be directly connected to the base station antenna 200 or indirectly connected to it via the antenna mounting component 41; no restriction is placed here. The base station antenna 200 can rotate around an axis parallel to the horizontal plane under the drive of the pitch drive component 42, thereby achieving tilt adjustment of the base station antenna 200. The pitch drive component 42 also serves as a drive source, providing driving force for the pitch movement of the base station antenna 200. Since the pitch movement of the base station antenna 200 is driven by the pitch drive component 42, the action of the pitch drive component 42 can be controlled by an electronic control program, which is beneficial for achieving linear adjustment of the tilt angle of the base station antenna 200. In addition, the tilt adjustment data of the base station antenna 200 can be recorded by software. During the adjustment process, the performance parameters of the base station antenna 200 can be monitored simultaneously, which is beneficial to adjusting the base station antenna 200 to the optimal state. The data recording of the adjustment process is complete and clear, which is convenient for management.

[0052] After the base station antenna 200 is installed at a high position by the base station antenna mounting and adjusting device 100, the height of the base station antenna 200 can be adjusted by the lifting mechanism 2, the azimuth angle of the base station antenna 200 can be adjusted by the deflection mechanism 3, and the tilt angle of the base station antenna 200 can be adjusted by the tilt mechanism 4, so that the signal coverage of the base station antenna 200 meets the on-site usage requirements.

[0053] In some embodiments, the base station antenna mounting and adjustment device 100 may further include a communication unit, which may include a wired communication unit or a wireless communication unit. Remote communication can be performed via the communication unit to remotely control the operation of the lifting mechanism 2, the deflection mechanism 3, and the tilt mechanism 4. In this way, remote automatic adjustment of the height, azimuth, and tilt angle of the base station antenna 200 can be achieved.

[0054] During use, the base station antenna 200 can be remotely controlled by lifting mechanism 2 to adjust its height, deflection mechanism 3 to adjust its azimuth, and tilt mechanism 4 to adjust its tilt. This allows for obtaining ideal performance data for the base station antenna 200, meeting the needs of different scenarios, improving the effectiveness of adjustment, increasing the signal coverage of the base station antenna 200, providing higher quality communication, and enhancing ease of use.

[0055] The base station antenna installation and adjustment device 100 of this application embodiment is used to install the base station antenna 200 to a communication base station. By setting up a lifting mechanism 2, a deflection mechanism 3, and a tilt mechanism 4, the height, azimuth, and tilt angle of the base station antenna 200 can be automatically adjusted, eliminating the need for manual adjustment, testing, and confirmation at height. The installation and adjustment process of the base station antenna 200 is simple and convenient to use, improving debugging and installation efficiency and reducing operational safety risks. By employing a lifting drive component 22, a deflection drive component 32, and a tilt drive component 42, the height, azimuth, and tilt angle of the base station antenna 200 can be adjusted. The linear adjustment offers higher precision, allowing for one-time adjustment to the target position, reducing the number of adjustment tests and repetitive operations. Its high accuracy enables precise adjustment to the target state, facilitating the achievement of optimal performance parameters for the base station antenna 200. Furthermore, it facilitates remote adjustment, eliminating the need for personnel to ascend the tower; control can be performed remotely from the control room, significantly reducing operational safety hazards and maintenance costs. It allows for convenient adjustment of the base station antenna 200's height, azimuth, and tilt angles during use, meeting the needs of various scenarios and increasing the signal coverage of the base station antenna 200 to improve communication performance.

[0056] In some embodiments, the lifting drive 22 can be a drive source that outputs rotational motion. For example, the lifting drive 22 may include, but is not limited to, a rotary motor, a hydraulic motor, an engine, etc.

[0057] In some specific embodiments, the lifting drive component 22 can be a motor, and the height adjustment data of the lifting mechanism 2 can be recorded by the motor's encoder and software.

[0058] See Figure 1 and Figure 2 The lifting mechanism 2 also includes a lifting transmission component 23, which extends along the lifting direction Z; the lifting mounting component 21 is connected to the lifting transmission component 23. The lifting drive component 22 and the lifting transmission component 23 are in a transmission cooperation, which can convert the rotational motion output by the lifting drive component 22 into the movement of the lifting mounting component 21 along the lifting direction Z.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the lifting drive component 22 is installed on the fixed installation assembly 1. The lifting drive component 22 is connected to the lifting transmission component 23. The lifting drive component 22 drives the lifting transmission component 23 to move along the lifting direction Z or rotate around the axis extending along the lifting direction Z. The lifting transmission component 23 drives the lifting installation component 21 to move along the lifting direction Z.

[0060] In some embodiments, the lifting transmission component 23 can move along the lifting direction Z. For example, the lifting transmission component 23 may include, but is not limited to, a chain, a conveyor belt, or a traction rope. The lifting mounting component 21 is fixedly connected to the chain, conveyor belt, or traction rope. The lifting drive component 22 drives the chain, conveyor belt, or traction rope to move along the lifting direction Z, thereby causing the lifting mounting component 21 to move along the lifting direction Z. In other embodiments, the lifting transmission component 23 can rotate about an axis extending along the lifting direction Z. For example, the lifting transmission component 23 may include, but is not limited to, a screw. The lifting mounting component 21 may include a nut connected to the screw, and the central axis of the screw extends along the lifting direction Z. The lifting drive component 22 drives the screw to rotate about its central axis. When the screw rotates, the nut can move up and down along the screw, thereby causing the lifting mounting component 21 to move along the lifting direction Z.

[0061] In some specific embodiments, one end of the screw is connected to the motor output shaft, and the other axial end of the screw can be connected to the fixed mounting assembly 1 via a bearing. This helps to improve the rotational stability of the screw.

[0062] In other embodiments, the lifting drive component 22 is disposed on the lifting mounting component 21, and the lifting transmission component 23 is fixedly disposed on the fixed mounting assembly 1; the lifting drive component 22 drives the lifting mounting component 21 to move along the lifting transmission component 23, thereby realizing the movement of the lifting mounting component 21 in the lifting direction Z. For example, the lifting transmission component 23 may include, but is not limited to, a screw, etc., with different fixing methods, and the central axis of the screw extends along the lifting direction Z; the lifting mounting component 21 may include a nut, which is connected to the screw, and the lifting drive component 22 is disposed on the lifting mounting component 21 and drives the nut to rotate around the screw, and the nut drives the lifting mounting component 21 to move along the screw, thereby realizing the movement of the lifting mounting component 21 in the lifting direction Z.

[0063] It should be noted that in some embodiments not shown, the lifting drive component 22 can also be a drive source that outputs linear motion. For example, the lifting drive component 22 can be, but is not limited to, a hydraulic jack, an electric jack, etc., which pushes the lifting mounting component 21, thereby realizing the movement of the lifting mounting component 21 along the lifting direction Z. The lifting motion of the lifting mounting component 21 can adopt different motion drive forms, and the lifting drive component 22 can adopt different drive sources accordingly. The embodiments of this application do not limit the specific driving method of the lifting drive component 22.

[0064] In some embodiments, see Figure 1 and Figure 2 The fixed mounting assembly 1 may include a first mounting base plate 11 and a second mounting base plate 12, which are spaced apart along the lifting direction Z. The lifting transmission component 23 is connected between the first mounting base plate 11 and the second mounting base plate 12.

[0065] In some embodiments, see Figure 1 and Figure 2 The lifting mechanism 2 also includes a lifting guide 24, which is fixedly connected to the fixed installation assembly 1 and extends along the lifting direction Z; the lifting installation assembly 21 is slidably connected to the lifting guide 24.

[0066] In some embodiments, the lifting guide 24 may be a guide post, which is vertically connected between the first mounting base 11 and the second mounting base 12. There may be multiple lifting guides 24, for example, three; these multiple lifting guides 24 are arranged at angular intervals around the lifting transmission member 23. The lifting mounting member 21 has holes or sleeves corresponding to the guide posts, and the holes or sleeves slide in engagement with the guide posts.

[0067] By setting the lifting guide 24 to slide in connection with the lifting mounting component 21, the movement of the lifting mounting component 21 along the lifting direction Z can be guided and limited to maintain the stability of the lifting movement of the lifting mounting component 21; moreover, the lifting guide 24 can suppress the rotation tendency of the lifting mounting component 21, which is beneficial to improving the stability of the lifting movement of the lifting mounting component 21.

[0068] In some embodiments, the deflection drive 32 can be a drive source that outputs rotational motion, such as a rotary motor, hydraulic motor, engine, etc. The deflection drive 32 is connected to the deflection mounting member 31 via a transmission mechanism, such as gear meshing or pulley transmission, thereby driving the deflection mounting member 31 to rotate around the deflection axis O1. In other embodiments, the deflection drive 32 can also be a drive source that outputs linear motion, such as a linear motor, cylinder, hydraulic cylinder, etc. The deflection drive 32 can be connected to the deflection mounting member 31 via a connecting rod, rack, etc., pushing the deflection mounting member 31 to rotate around the deflection axis O1. This application does not limit the specific driving method of the deflection drive 32.

[0069] In some specific embodiments, the deflection drive 32 can be a motor, and the azimuth adjustment data of the deflection mechanism 3 can be recorded by the motor's encoder and software.

[0070] In some embodiments, see Figure 1 , Figure 3 and Figure 4The lifting mounting component 21 includes a first mounting plate 211, a second mounting plate 212, and a lifting connector 213 vertically connected between the first mounting plate 211 and the second mounting plate 212. The first mounting plate 211 is provided with a first guide portion (not shown in the figure) surrounding the lifting connector 213, and the second mounting plate 212 is provided with a second guide portion 214 surrounding the lifting connector 213. The central axis of the first guide portion and the central axis of the second guide portion 214 are both coaxial with the deflection axis O1. The deflection mounting component 31 is slidably connected to the first guide portion and the second guide portion 214.

[0071] The lifting connector 213 is used for transmission connection with the lifting drive component 22. In some embodiments, the lifting connector 213 can be a connecting sleeve with a connecting threaded hole 2131. The connecting sleeve is connected to the screw through the connecting threaded hole 2131. The lifting drive component 22 drives the screw to rotate, and the screw drives the connecting sleeve to move along the screw, thereby driving the lifting mounting component 21 to move in the lifting direction Z.

[0072] The first mounting plate 211 and the second mounting plate 212 are used to mount the deflection mechanism 3. The deflection drive 32 can be mounted on either the first mounting plate 211 or the second mounting plate 212. The deflection mounting member 31 is slidably connected to the first guide portion and the second guide portion 214, thereby slidably mounting the deflection mounting member 31 on the lifting mounting member 21. Moreover, the first guide portion and the second guide portion 214 restrict the movement of the deflection mounting member 31 along the circumferential direction around the deflection axis O1, thereby realizing the azimuth angle adjustment of the base station antenna 200.

[0073] In some embodiments, the first guide portion and the second guide portion 214 may be structures such as a slide groove, a guide rail or a bearing, and the deflection mounting member 31 is slidably connected to the slide groove, guide rail or bearing, thereby limiting the movement trajectory of the deflection mounting member 31.

[0074] In some embodiments, a first guide hole 2111 is provided on the first mounting plate 211, and a second guide hole 2121 is provided on the second mounting plate 212, with the first guide hole 2111 and the second guide hole 2121 being coaxially arranged. A guide post is movably inserted through the first guide hole 2111 and the second guide hole 2121 to guide and limit the movement of the lifting mounting component 21 along the lifting direction Z.

[0075] By setting the first guide part and the second guide part 214, the movement trajectory of the deflection mounting part 31 is limited along the circumferential direction around the deflection axis O1, which can improve the stability of the deflection mounting part 31 rotating around the deflection axis O1, and help improve the stability and accuracy of adjusting the azimuth angle of the base station antenna 200.

[0076] In some embodiments, such as Figure 3 and Figure 4As shown, the first guide portion is disposed on the side of the first mounting plate 211 facing the second mounting plate 212, and the second guide portion 214 is disposed on the side of the second mounting plate 212 facing the first mounting plate 211; one end of the deflection mounting member 31 is slidably connected to the first guide portion, and the other end of the deflection mounting member 31 is slidably connected to the second guide portion 214.

[0077] In some specific embodiments, the first guide portion and the second guide portion 214 are grooves extending in a circumferential direction around the deflection axis O1; the deflection mounting member 31 can be a mounting plate, with the upper end of the mounting plate inserted into the groove on the first mounting plate 211 and the lower end of the mounting plate inserted into the groove on the second mounting plate 212, thereby restricting the movement trajectory of the mounting plate around the deflection axis O1.

[0078] In some embodiments, see Figure 1 and Figures 3 to 5 The deflection mechanism 3 also includes a gear ring 33, the central axis of which is coaxial with the deflection axis O1; the deflection mounting part 31 is connected to the gear ring 33, and the deflection driving part 32 is connected to the gear ring 33 in a transmission.

[0079] The teeth of the gear ring 33 can be located on either the inner or outer ring of the gear ring 33; there is no limitation on this. The gear ring 33 is driven to rotate around the central axis by the deflection drive 32, and the gear ring 33 drives the deflection mounting part 31 to rotate around the deflection axis O1, thereby realizing the azimuth angle adjustment of the base station antenna 200.

[0080] In some embodiments, the deflection mounting member 31 is fixedly connected to the outer ring of the gear ring 33, and the inner ring of the gear ring 33 is toothed. The deflection drive member 32 is disposed on the lifting mounting member 21 and located on the inner ring of the gear ring 33; the deflection mechanism 3 also includes a drive wheel 34, which can be a gear, connected to the output end of the deflection drive member 32 and meshing with the gear ring 33. This results in a more compact structure, which helps to reduce the space occupied by the base station antenna mounting and adjustment device 100.

[0081] In some embodiments, see Figure 1 and Figures 3 to 5 The deflection mechanism 3 includes a plurality of deflection mounting parts 31, which are spaced apart along the circumferential direction surrounding the deflection axis O1.

[0082] By setting multiple deflection mounting parts 31, multiple tilting mechanisms 4 and multiple base station antennas 200 can be installed to achieve azimuth angle adjustment of multiple base station antennas 200, which can meet the usage requirements in different scenarios, and is conducive to increasing the signal coverage and improving the communication effect.

[0083] In some embodiments, see Figure 5The deflection mechanism 3 includes multiple gear rings 33, which are arranged sequentially along the lifting direction Z. Each deflection mounting component 31 is connected to a gear ring 33. The deflection mechanism 3 also includes a shift gear set 35, which includes a shift gear shaft 351, a transmission wheel 352 connected to the shift gear shaft 351, and multiple driven gears 353. The transmission wheel 352 is connected to the deflection drive component 32. The shift gear shaft 351 extends along the lifting direction Z and can move along the lifting direction Z to switch the corresponding driven gear 353 and gear ring 33 meshing.

[0084] In some embodiments, the output end of the deflection drive 32 may be connected to a drive wheel 34, and the drive wheel 34 and the transmission wheel 352 may be gears, with the drive wheel 34 meshing with the transmission wheel 352; or the drive wheel 34 may be connected to the transmission wheel 352 by a chain or transmission belt. The deflection drive 32 drives the drive wheel 34 to rotate, and the drive wheel 34 drives the transmission wheel 352 to rotate.

[0085] The shift gear shaft 351 moves axially, driving multiple passive gears 353 to move along the lifting direction Z, so that one of the passive gears 353 meshes with its corresponding gear ring 33. At this time, the deflection drive 32 drives the transmission wheel 352 to rotate, the transmission wheel 352 drives the shift gear shaft 351 to rotate, the shift gear shaft 351 drives the passive gear 353 to rotate, the passive gear 353 drives the meshing gear ring 33 to rotate, and then drives the deflection mounting part 31 connected to the gear ring 33 to rotate around the deflection axis O1, thereby realizing the azimuth angle adjustment of the base station antenna 200.

[0086] By controlling the axial movement of the shift gear shaft 351, the deflection drive 32 can be switched to drive different gear rings 33 to rotate, thereby switching and adjusting the azimuth angle of different base station antennas 200. Taking the adjustment of two sets of base station antennas 200 as an example, the motor drives the shift gear shaft 351 to rotate. There are two driven gears 353 on the shift gear shaft 351. By controlling the axial shift of the shift gear shaft 351, the gear ring 33 can be switched to mesh with its corresponding driven gear 353, so that the azimuth angle of the two sets of base station antennas 200 can be adjusted independently.

[0087] By setting multiple gear rings 33 and shift gear sets 35 to form a shift mechanism, the azimuth angle of multiple base station antennas 200 can be adjusted individually for each antenna. It is convenient to use, and the structure of the shift mechanism is compact, which helps to reduce the space occupied by the base station antenna installation adjustment device 100.

[0088] Of course, in other embodiments, a deflection drive 32 can also be added, that is, each deflection mounting part 31 is provided with a corresponding deflection drive 32, so as to realize the azimuth angle adjustment of multiple base station antennas 200.

[0089] In some embodiments, the pitch drive 42 can be a drive source that outputs rotational motion. For example, the pitch drive 42 can be, but is not limited to, a rotary motor, a hydraulic motor, or an engine. The pitch drive 42 is connected to the base station antenna 200 via a transmission mechanism, such as gear meshing or pulley transmission, thereby driving the base station antenna 200 to pitch and rotate. In other embodiments, the pitch drive 42 can also be a drive source that outputs linear motion. For example, the pitch drive 42 can be, but is not limited to, an electric push rod, a pneumatic push rod, or a hydraulic push rod. The pitch drive 42 can be connected to the base station antenna 200 via a push rod or connecting rod, thereby driving the base station antenna 200 to pitch and rotate. This application does not limit the specific driving method of the pitch drive 42.

[0090] In some specific embodiments, the pitch drive 42 can be an electric actuator, which can record the tilt adjustment data of the tilt mechanism 4 through the encoder and software of the electric actuator.

[0091] In some embodiments, see Figure 1 , Figure 3 , Figure 5 and Figure 6 The antenna mounting component 41 includes a first connector 411, which is disposed on the deflection mounting component 31 and has a first hinge portion 4111. The pitch drive component 42 is disposed on the deflection mounting component 31 and is spaced apart from the first connector 411 in the lifting direction Z. The pitch drive component 42 has a second hinge portion 421. The hinge axis of the first hinge portion 4111 and the hinge axis of the second hinge portion 421 are both perpendicular to the deflection axis O1. The first hinge portion 4111 and the second hinge portion 421 are used to rotatably mount the base station antenna 200.

[0092] The pitch drive 42 is used to drive the base station antenna 200 to rotate around the hinge axis of the first hinge portion 4111, thereby adjusting the tilt angle of the base station antenna 200. The hinge axis of the first hinge portion 4111 is the pitch axis O2 of the base station antenna 200. For example, the pitch drive 42 can be an electric push rod. Driven by the electric push rod, the distance between the upper end of the base station antenna 200 and the deflection mounting member 31 is adjusted, and the lower end of the base station antenna 200 rotates around the first hinge portion 4111, thereby achieving the adjustment of the tilt angle of the base station antenna 200. The tilt angle data of the base station antenna 200 can be calculated by recording the encoder data of the electric push rod and the function of the first connector 411.

[0093] By setting the base station antenna 200 to a hinged installation method, the number of bolts used in the installation process can be greatly reduced, the installation and fastening are simple, and the accuracy requirements of the installation process are reduced, which effectively improves the efficiency of debugging and installation and reduces the safety risks of operation.

[0094] In some embodiments, see Figure 3 , Figure 6 and Figures 8 to 10 The antenna mounting component 41 also includes a second connector 412, one end of which is hinged to a second hinge portion 421, and the other end of the second connector 412 is provided with a third hinge portion 4121.

[0095] The second connector 412 is connected to the pitch drive 42. The pitch drive 42 can drive the second connector 412 to rotate about an axis parallel to the pitch axis O2 and / or move in a direction perpendicular to the pitch axis O2. By setting the second connector 412, base station antennas 200 with different installation spacings and sizes can be adapted. The installation spacing of the base station antennas 200 will not affect the tilt angle of the base station antennas 200, resulting in stronger compatibility. Moreover, operators do not need to perform precise installation on the tower, and the installation process of the base station antennas 200 is simple and convenient, further improving installation efficiency and reducing operational safety risks.

[0096] In some embodiments, see Figure 5 and Figure 6 One end of the pitch drive 42 is hinged to the deflection mount 31, and the other end of the pitch drive 42 is provided with a second hinge part 421.

[0097] By setting the pitch drive component 42 and the deflection mounting component 31 to be hinged, base station antennas 200 with different installation spacing and different sizes can be adapted. The tilt angle of the base station antenna 200 is not limited by the installation distance of the base station antenna 200 or whether the operation of the installation personnel is standardized, which improves the compatibility of the installation of the base station antenna 200 and the accuracy of the tilt angle adjustment. Moreover, the installation process of the base station antenna 200 is simple and convenient, which helps to improve installation efficiency and reduce operational safety risks.

[0098] In some embodiments, see Figure 5 , Figure 7 and Figure 8 The antenna mounting component 41 also includes a mounting hinge 413, which is used to mount on the base station antenna 200. The mounting hinge 413 is provided with a fourth hinge part 4131.

[0099] The fourth hinge portion 4131 can be hinged with the first hinge portion 4111, the second hinge portion 421 or the third hinge portion 4121.

[0100] By setting the mounting hinge 413, it is possible to accommodate base station antennas 200 with different installation spacings and sizes, achieving universal installation for various base station antennas 200. The mounting hinge 413 can be used as an installation interface for the base station antenna 200. Antenna manufacturers only need to reserve a standard interface for connecting the mounting hinge 413, such as a mounting hole, making installation simple and convenient. In this way, the installation interface of the base station antenna 200 is standardized, and the specifications and models of installation accessories from antenna manufacturers are standardized, which can reduce development and operation management costs, simplify management, reduce errors, and standardize and unify antenna operation installation work, thus helping to reduce operator training and learning costs.

[0101] In some embodiments, see Figures 8 to 11 The lifting mounting component 21 includes a lifting connector 213 and at least one limiting component 215. The limiting component 215 is connected to the lifting connector 213 and is also provided with a limiting guide hole 2151. The central axis of the limiting guide hole 2151 extends along the lifting direction Z. The deflection mounting component 31 is rotatably sleeved on the lifting connector 213. The central axis of the deflection mounting component 31 is coaxial with the deflection axis O1.

[0102] In this embodiment, the base station antenna mounting adjustment device 100 can be installed on the mast 300 of the communication base station. The lifting connector 213 is used for transmission connection with the lifting drive 22. The limiting guide hole 2151 of the limiting member 215 is used to connect to the mast 300 to install the lifting mounting member 21 on the mast 300; the limiting member 215 can suppress the rotation tendency of the lifting mounting member 21, which is beneficial to improving the lifting stability of the lifting movement of the lifting mounting member 21. Moreover, the diameter of the limiting guide hole 2151 is larger than the outer diameter of the mast 300, so that the limiting member 215 can slide along the mast 300; thus, the mast 300 can serve as a guide structure for the lifting mounting member 21, which can guide and limit the movement of the lifting mounting member 21 along the lifting direction Z, which is beneficial to maintaining the lifting stability of the lifting movement of the lifting mounting member 21.

[0103] In some embodiments, the fixed mounting assembly 1 is fixed to the mast 300 via a first mounting base 11 and a second mounting base 12. A screw is rotatably connected between the first mounting base 11 and the second mounting base 12. The lifting connector 213 can be a connecting sleeve with a connecting threaded hole 2131, which is connected to the screw. The lifting drive 22 drives the screw to rotate, and the screw drives the connecting sleeve to move along the screw, thereby causing the lifting mounting assembly 21 to move in the lifting direction Z, thus realizing the adjustment of the height of the base station antenna 200.

[0104] In some embodiments, the deflection mounting member 31 can be a roller, which is rotatably sleeved on the outside of the lifting connector 213. The central axis of the roller is coaxial with the deflection axis O1, and a gear rack 36 is provided on the outer peripheral wall of the roller. The deflection drive member 32 is provided on a limiting member 215, and a drive wheel 34 is connected to the output shaft of the deflection drive member 32. The drive wheel 34 meshes with the gear rack 36. Under the drive of the deflection drive member 32 and the drive wheel 34, the gear rack 36 drives the roller to rotate around the central axis. At the same time, the tilting mechanism 4 is provided on the roller. The rotation of the roller around the central axis drives the base station antenna 200 to rotate around the deflection axis O1, thereby realizing the adjustment of the azimuth angle of the base station antenna 200.

[0105] The tilt mechanism 4 can adjust the tilt angle of the base station antenna 200.

[0106] The base station antenna mounting adjustment device 100 in this embodiment can adjust the height, azimuth angle and tilt angle of a single base station antenna 200. It has a simple structure, is easy to use, and occupies less space, which is conducive to meeting the arrangement requirements of the base station antenna 200.

[0107] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0108] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
