Description

Technical Field

[0001] This application relates to the field of communication antenna technology, specifically a communication antenna elevation angle adjustment and fixing device. Background Technology

[0002] Communication antennas, especially directional antennas widely used in mobile communications, satellite communications, and wireless broadcasting, rely heavily on precise elevation angles for signal coverage quality and transmission efficiency. During base station construction and subsequent network optimization, technicians must accurately adjust and reliably fix the antenna's elevation angle based on requirements such as coverage area, terrain obstacles, and interference avoidance.

[0003] Currently, the adjustment of the elevation angle of communication antennas mainly relies on manually operated mechanical devices. The common structure is to set an adjustable hinge mechanism between the antenna mast and the mounting bracket, and fix the angle with bolts, racks or simple screws. However, in long-term practical applications, most of the adjustments of this existing technology need to be manually completed by maintenance personnel with tools in a high-altitude working environment. The process is cumbersome and highly dependent on the experience of the personnel. It requires technicians to go to the site to perform high-altitude operations, which not only results in slow response speed and high maintenance costs, but also brings safety risks associated with working at height.

[0004] Therefore, this application provides a communication antenna elevation angle adjustment and fixing device to solve the above problems. Summary of the Invention

[0005] This application provides a communication antenna elevation angle adjustment and fixing device, which aims to solve the problem mentioned in the background art that the adjustment of the elevation angle of existing communication antennas mainly relies on manual operation, requiring technicians to go to the site to perform high-altitude operations, which poses a safety risk of working at height.

[0006] To achieve the above objectives, this application provides the following technical solution: a communication antenna elevation angle adjustment and fixing device, including a mast and a locking sleeve fitted on the mast, an assembly rod fixedly installed on the locking sleeve, an antenna frame installed at the end of the assembly rod away from the locking sleeve, and a fixing mechanism provided at the lower end of the mast;

[0007] The fixing mechanism includes a chassis and a stainless steel boss mounted on the chassis. The chassis has a plurality of threaded holes arranged in a ring. An adjusting seat is provided on the inner side of the stainless steel boss. A fixed shaft for rotatably connecting with the stainless steel boss is fixedly installed at the lower end of the adjusting seat. A sleeve is fixedly installed at the upper end of the adjusting seat. A U-shaped plate for clamping the rod is provided inside the sleeve. A worm gear assembly is provided on one side of the stainless steel boss. One end of the fixed shaft passes through the stainless steel boss and is connected to the worm gear of the worm gear assembly.

[0008] Preferably, there are two sets of U-shaped plates, and the two sets of U-shaped plates are symmetrically distributed on the inner side of the sleeve. A cylinder is fixedly installed on the side of the U-shaped plate away from the clamping rod. A spring is fixedly installed inside the cylinder. The end of the spring away from the U-shaped plate is fixedly connected to the inner side of the sleeve. The symmetrically distributed U-shaped plate structure can apply clamping force evenly, avoiding the problem of clamping rod bending or insecure clamping caused by unilateral force application.

[0009] Preferably, a shaft handwheel is symmetrically threaded onto the sleeve, the shaft of the shaft handwheel is horizontally aligned with the cylinder on the U-shaped plate, and a spring is sleeved outside the shaft of the shaft handwheel. Preferably, a housing support is installed at the lower end of the worm gear assembly, and the lower end of the housing support is fixedly connected to the chassis by bolts.

[0010] Preferably, a servo motor is installed inside the housing support. The base of the servo motor is fixedly connected to the upper end of the chassis by bolts, and a shock-absorbing pad is provided at the connection. The output end of the servo motor passes through one end of the housing support. Both the output end of the servo motor and the worm on the worm gear assembly are fitted with drive gear cylinders. The two drive gear cylinders are meshed and fitted together by a transmission gear belt. A protective shell for covering the transmission gear belt is fixedly installed on the outside of the housing support. The use of a servo motor drive enables remote control, precise programming, and automated operation of the antenna's elevation angle adjustment, greatly improving maintenance efficiency and accuracy.

[0011] This fixing device integrates and connects the upper structural components through the chassis, improving the efficiency of the pre-installation work. At the same time, the combination of worm gear transmission and servo motor achieves high-precision angle adjustment and strong self-locking fixing capability, resisting wind and vibration.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] This embodiment provides a communication antenna elevation angle adjustment and fixing device, such as... Figure 1-3 As shown, the fixing device includes a mast 1 and a locking sleeve 22 fitted on the mast 1. An assembly rod 2 is fixedly installed on the locking sleeve 22. An antenna frame 21 is installed at the end of the assembly rod 2 away from the locking sleeve 22. A fixing mechanism 3 is provided at the lower end of the mast 1.

[0018] The fixing mechanism 3 includes a chassis 31 and a stainless steel boss 32 mounted on the chassis 31. The chassis 31 has several threaded holes arranged in a ring. An adjusting seat 33 is provided on the inner side of the stainless steel boss 32. A fixed shaft 331 for rotatably connecting with the stainless steel boss 32 is fixedly installed at the lower end of the adjusting seat 33. A sleeve 34 is fixedly installed at the upper end of the adjusting seat 33. A U-shaped plate 341 for clamping the clamping rod 1 is provided inside the sleeve 34. A worm gear assembly 35 is provided on one side of the stainless steel boss 32. One end of the fixed shaft 331 passes through the stainless steel boss 32 and is connected to the worm gear of the worm gear assembly 35.

[0019] Specifically, the fixed shaft 331 is driven to rotate by the worm gear assembly 35, thereby causing the adjustment seat 33 and the sleeve 34 and the rod 1 above to change the pitch angle as a whole. The self-locking characteristic of the worm gear makes it impossible to reverse once the angle is set without external force, thus achieving stable fixation. The stainless steel boss 32 is integrally formed with the upper end of the chassis 31. The chassis 31 is fixed and installed by bolts through holes drilled in the ground under normal conditions.

[0020] There are two sets of U-shaped plates 341, and the two sets of U-shaped plates 341 are symmetrically distributed on the inner side of the sleeve 34. A cylinder is fixedly installed on the side of the U-shaped plate 341 away from the rod 1. A spring 342 is fixedly installed inside the cylinder. The end of the spring 342 away from the U-shaped plate 341 is fixedly connected to the inner side of the sleeve 34.

[0021] More specifically, two sets of U-shaped plates 341 surround and clamp the retaining rod 1 from both sides, and the shaft handwheel 343 serves as a guide and connecting rod to ensure that the U-shaped plates 341 can only move in the axial direction and will not deflect.

[0022] A shaft handwheel 343 is symmetrically threaded onto the sleeve 34. The shaft of the shaft handwheel 343 is horizontally aligned with the cylinder on the U-shaped plate 341, and the spring 342 is sleeved on the outside of the shaft of the shaft handwheel 343.

[0023] Furthermore, by rotating the shaft handwheel 343, its shaft moves inward and presses against the cylinder on the U-shaped plate 341, thereby driving the two sets of U-shaped plates 341 to move towards each other, and finally tightly hug the gripping rod 1. The spring 342 plays the role of pre-clamping the gripping rod 1, and at the same time, it adapts to gripping rods 1 of different specifications. The front end of the shaft of the shaft handwheel 343 is provided with a rubber pad to increase the friction.

[0024] The lower end of the worm gear assembly 35 is equipped with a housing support 36, and the lower end of the housing support 36 is fixedly connected to the chassis 31 by bolts.

[0025] It should be noted that the housing support 36 serves as the mounting base for the worm gear assembly 35 and firmly fixes it to the chassis 31 to ensure that the transmission system will not be displaced or deformed when subjected to force.

[0026] A servo motor is installed inside the housing support 36. The base of the servo motor is fixedly connected to the upper end of the chassis 31 by bolts, and a shock-absorbing pad is provided at the connection. The output end of the servo motor passes through one end of the housing support 36. Both the output end of the servo motor and the worm on the worm gear assembly 35 are fitted with drive gear cylinders. The two drive gear cylinders are meshed and fitted through the transmission gear belt 38. A protective shell 37 for covering the transmission gear belt 38 is fixedly installed on the outside of the housing support 36.

[0027] It is worth mentioning that the servo motor, as the power source, transmits power to the worm gear assembly 35 through the drive gear cylinder and transmission belt 38, ultimately driving the entire pitch mechanism. The protective housing 37 protects the transmission belt 38 from dust, rain, and accidental contact. The servo motor is electrically connected to the remote control center and receives angle adjustment commands from the control center. The device can also integrate a tilt sensor for real-time feedback of the antenna's actual pitch angle, thereby achieving extremely high accuracy in angle setting and status monitoring.

[0028] In use, the chassis 31 is fixed to the ground with bolts beforehand. The handwheels 343 on both sides of the sleeve 34 are rotated to drive the two sets of U-shaped plates 341 to firmly clamp the communication rod 1, thereby fixing the base of the device. The servo motor is driven to drive the worm gear assembly 35 through the transmission belt 38. The worm drives the worm wheel, which in turn drives the fixed shaft 331 and the adjusting seat 33, thereby precisely changing the pitch angle of the sleeve 34 and the rod 1. After the adjustment is completed, the self-locking characteristic of the worm gear automatically locks the angle.

[0029] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
