Description

Technical Field

[0001] This invention relates to the field of communication base station technology, and more specifically to a vibration damping device for communication base station equipment. Background Technology

[0002] Communication base stations are the core infrastructure of mobile communication networks. They are responsible for transmitting information to mobile phones and other terminal devices via radio waves within a certain coverage area, enabling wireless communication functions such as calls and internet access. When installing electromechanical equipment, shock absorption devices are often required to ensure that the equipment is protected from damage caused by excessive vibration during use.

[0003] Currently, existing shock absorption devices are under dynamic loads for extended periods, which may lead to problems such as rubber aging, airbag leakage, and metal fatigue. In addition, elastic materials are subject to creep and stress relaxation. Even under normal operating conditions, the shock absorption performance will slowly decline over time. Maintenance requires professional personnel and tools, resulting in long maintenance cycles, high costs, and reduced equipment availability.

[0004] Based on this, the present invention designs a vibration damping device for communication base station equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as long maintenance cycles and high costs, by proposing a vibration damping device for communication base station equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vibration damping device for communication base station equipment, comprising: The base plate is used for installing and fixing the shock absorption device to the mounting interface; The shock-absorbing brackets are fixedly installed on the upper part of the base plate, and the two shock-absorbing brackets are symmetrically arranged to provide elastic support. A fixed chuck is fixedly connected to the lower end between the two shock-absorbing brackets; A rubber air spring is embedded in the fixed chuck to buffer impacts and high-frequency vibrations; A detachable chuck is located at the upper end between the two shock-absorbing brackets and is used to clamp and fix the upper end of the rubber air spring. The equipment mounting plate is fixedly installed on the upper end of the two shock-absorbing brackets, and the lower surface of the equipment mounting plate is fixedly connected to the detachable chuck, for installing communication base station equipment; The first connecting bolt is used for mounting and fixing the two ends of the detachable chuck to the two shock-absorbing brackets; The second connecting bolt is used for installing and fixing the shock-absorbing bracket to the base plate.

[0007] As a preferred embodiment of the present invention, the shock-absorbing bracket includes: A base frame is used for the fixed installation of the shock-absorbing bracket to the base plate via a second connecting bolt; A limiting mechanism is provided at the upper end of the base frame, and two limiting mechanisms are symmetrically arranged front and rear to limit the off-center load of the equipment mounting plate; A support plate is disposed above the base frame and is movably connected to two limiting mechanisms, and two hinge seats are symmetrically arranged at the lower end of the center of the support plate; The grooves are symmetrically formed on the upper end of the base frame, and there are two grooves in total; A slide bar is disposed within the groove; A slide block is disposed within the groove and slidably connected to the slide rod; A connecting rod is disposed between the base frame and the support plate. One end of the connecting rod is movably hinged to the slide block, and the other end is movably hinged to the hinge seat of the support plate. A second spring is sleeved on the slide rod, with one end of the second spring fixedly connected to the inner wall of the groove and the other end fixedly connected to the slide block in the groove on the same side.

[0008] As a preferred embodiment of the present invention, the limiting mechanism includes: Mounting base for fixed installation with the base frame; The upright is vertically fixed inside the mounting base; Install the top seat, which is slidably sleeved onto the upright and fixedly installed to the lower end of the support plate; The first spring is sleeved on the upright and located between the mounting base and the mounting top. A threaded head is provided at the top of the upright that protrudes from the support plate; A nut, screwed onto the threaded head, is used for fixed installation with the equipment mounting plate.

[0009] As a preferred embodiment of the present invention, the upper surface of the fixed chuck body is provided with a groove that matches the shape of the lower end of the rubber air spring, and the lower surface of the detachable chuck body is provided with a groove that matches the shape of the upper end of the rubber air spring, for wrapping and fixing the rubber air spring.

[0010] As a preferred embodiment of the present invention, the equipment mounting plate has mounting holes at all four corners for mounting the equipment mounting plate on the upper end of the support plate of the two shock-absorbing brackets.

[0011] As a preferred embodiment of the present invention, the detachable chuck is fixedly connected to the lower surface of the equipment mounting plate, and is fixedly connected to the support plate of the shock-absorbing bracket by the first connecting bolt, so that the support plate, the detachable chuck and the equipment mounting plate form an integrated connection structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention introduces a modular design, allowing different components of the shock absorber to be flexibly disassembled. When the rubber air springs experience aging or air leakage, the nut is first removed from the threaded head, and then the first connecting bolt used to fix the detachable chuck is removed. The equipment mounting plate and the detachable chuck can then be removed from the shock absorber bracket as a whole, so that the detachable chuck loses its clamping and fixing of the rubber air spring. The rubber air spring can then be removed and replaced from the fixed chuck. When the spring elements in the shock absorber bracket experience stress relaxation or decreased shock absorption performance, the corresponding components can be replaced individually, facilitating quick maintenance, reducing overall maintenance costs and maintenance cycles. At the same time, the detachable structure facilitates the classification and recycling of rubber and metal components. 2. This invention combines the active air pressure buffer of the rubber air spring with the mechanical spring and sliding buffer of the shock absorber bracket to form a composite shock absorption structure, achieving efficient vibration isolation. The air cavity of the rubber air spring uses compressibility to buffer impact, while the rubber layer provides elastic deformation to absorb energy and suppress high-frequency vibration. The shock absorber bracket can provide stable support for the shock absorption device while further enhancing the shock absorption effect and avoiding damage from off-center loads.

[0015] The following will refer to the appendices in the embodiments of the present invention. Figures 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] Example Please see Figures 1-6 The present invention provides the following technical solution: a shock absorption device for communication base station equipment, comprising a base plate 1, a shock absorption bracket 2, a fixed chuck 3, a rubber air spring 4, a detachable chuck 5, an equipment mounting plate 6, a first connecting bolt 7, and a second connecting bolt 8. Two shock absorption brackets 2 are symmetrically installed on both sides of the upper end of the base plate 1 through the second connecting bolt 8. A fixed chuck 3 is fixedly connected between the two shock absorption brackets 2. A rubber air spring 4 is installed inside the fixed chuck 3. A detachable chuck 5 is provided at the upper end of the rubber air spring 4. An equipment mounting plate 6 is fixedly connected to the upper part of the detachable chuck 5. The two ends of the detachable chuck 5 are fixedly connected to the shock absorption bracket 2 through the first connecting bolt 7.

[0017] The shock absorber bracket 2 includes a base frame 201, limiting mechanisms 202, a support plate 203, a groove 204, a slide rod 205, a slide block 206, a connecting rod 207, and a second spring 208. Two limiting mechanisms 202 are symmetrically fixedly installed at the upper end of the base frame 201. Support plates 203 are movably installed on the two limiting mechanisms 202. Two hinge seats 2031 are symmetrically arranged at the center of the lower end of the support plates 203. Grooves 204 are symmetrically formed at the upper end of the base frame 201. Each groove 204 is provided with a slide rod 205, and each slide rod 205 is slidably connected to a slide seat 206. A connecting rod 207 is movably hinged to the slide seat 206. The upper end of the connecting rod 207 is movably hinged to the hinge seat 2031 of the corresponding support plate 203. A second spring 208 is provided between the slide seat 206 and the groove 204. The second spring 208 is sleeved on the slide rod 205. One end of the second spring 208 is fixedly connected to the groove 204, and the other end is fixedly connected to the slide seat 206.

[0018] The limiting mechanism 202 includes a mounting base 2021, a vertical rod 2022, a mounting top 2023, a first spring 2024, a threaded head 2025, and a nut 2026. The vertical rod 2022 is vertically fixed inside the mounting base 2021, and the mounting top 2023 is slidably connected to the vertical rod 2022. The first spring 2024 is connected between the mounting base 2021 and the mounting top 2023 and is sleeved on the outside of the vertical rod 2022. The mounting top 2023 is fixedly installed on the lower end of the support plate 203. The top of the vertical rod 2022 extends out of the support plate 203 and is provided with a threaded head 2025. A nut 2026 is screwed onto the threaded head 2025.

[0019] Specifically, the structural design of the shock absorber bracket 2 provides stable support for the equipment mounting plate 6 while enhancing the shock absorption effect. At the same time, the shock absorber bracket 2 adopts a detachable design, so when the spring element experiences stress relaxation or a decrease in shock absorption performance, the corresponding parts can be replaced individually, reducing the overall maintenance cost and maintenance cycle.

[0020] In this embodiment, the upper surface of the fixed chuck 3 is provided with a groove that matches the shape of the lower end of the rubber air spring 4, and the lower surface of the detachable chuck 5 is provided with a groove that matches the shape of the upper end of the rubber air spring 4, for wrapping and fixing the rubber air spring 4.

[0021] Specifically, the rubber air spring 4 mentioned above adopts a snap-fit ​​installation method, which facilitates the convenient replacement and maintenance of the consumable rubber air spring 4, thereby reducing the installation difficulty and time cost.

[0022] In this embodiment, the equipment mounting plate 6 is installed between the support plate 203 and the nut 2026. The detachable chuck 5 at the lower end of the equipment mounting plate 6 is fixedly connected to the support plate 203 by the first connecting bolt 7, thereby connecting the support plate 203, the detachable chuck 5 and the equipment mounting plate 6 to form an integrated structure.

[0023] Specifically, the integrated structure formed by the support plate 203, the detachable chuck 5, and the equipment mounting plate 6 passively floats along the upright 2022 when subjected to vibration, forming a composite shock absorption structure with the rubber air spring 4 to ensure the shock absorption effect of the device.

[0024] The working principle and usage process of this invention are as follows: In practical use, when the equipment mounted on the equipment mounting plate 6 is subjected to vibration or impact, the impact force will be transmitted and dissipated downwards through two paths simultaneously. Part of the energy is directly transmitted to the rubber air spring 4 secured by the detachable chuck 5 and the fixed chuck 3. The air chamber gas damping and elastic deformation of the rubber layer of the rubber air spring 4 buffer the impact, consume energy, and suppress high-frequency vibration. The other part of the energy is transmitted to the two shock-absorbing brackets 2 below the equipment mounting plate 6. When the support plate 203 moves downwards, it will drive the connecting rod 207 and the slide 206 to slide on the slide rod 205, compressing or stretching the second spring 208, further consuming energy. The limiting mechanism 202 can guide and limit the movement of the support plate 203, providing stable support and anti-eccentric load capability, while compressing or stretching... The first spring 2024 within the limiting mechanism 202 further buffers the vibration. The active air pressure buffer of the rubber air spring 4 works in conjunction with the passive mechanical spring and sliding buffer structure of the shock absorber bracket 2 to transform a single violent vibration into a slow-release motion of repeated compression and stretching of the spring and gas damping absorption, thereby achieving a highly efficient composite shock absorption effect and preventing equipment from being damaged by vibration. At the same time, when the core shock absorber element, the rubber air spring 4, ages or leaks, simply unscrew the nut 2026 of the limiting device mounting plate 6 and the first connecting bolt 7 used to connect the support plate 203 and the detachable chuck 5, and the equipment mounting plate 6 along with the detachable chuck 5 can be removed as a whole to expose and replace the rubber air spring. Similarly, if the performance of the spring element in the shock absorber bracket 2 deteriorates, the corresponding component can also be replaced separately, greatly shortening the maintenance cycle and reducing costs.

[0025] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
