Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more particularly to a vibration damping support device for air compressors. Background Technology

[0002] Air compressors, as core equipment for compressing gas, are widely used in mining, machinery manufacturing, tunnel construction, and other scenarios. During operation, they generate continuous vibrations, which not only affect the stability of the equipment but also transmit vibrations to the ground, causing noise and structural damage. Therefore, they require corresponding vibration-damping support devices to ensure effective operation. Existing conventional air compressor support devices are mostly simple brackets with ordinary springs, which only provide basic vibration damping.

[0003] For example, a vibration damping support frame for an air compressor with patent publication number "CN212960466U" achieves composite vibration damping by setting a combination structure of vibration damping spring and vibration damping air cushion at the bottom of the mounting base. At the same time, it is equipped with a protective plate and dustproof net to improve environmental adaptability, thus solving the problems of single vibration damping effect and insufficient protection of conventional devices.

[0004] However, the aforementioned patent uses a fixed support foot combined with a pulley structure. The support foot has a small contact area with the ground and weak grip. Long-term vibration can easily cause the device to shift. At the same time, the shock-absorbing components are separated from the support structure, making it impossible to further enhance the shock absorption effect through stable support, thus limiting the overall practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a vibration damping support device for air compressors, which solves the problems of the prior art.

[0006] To achieve the above objectives, the present invention provides a vibration damping support device for an air compressor, comprising a housing, wherein a support mechanism is provided inside the housing for supporting the device and fixing it to the ground, and a vibration damping mechanism is provided above the housing for damping the air compressor. The support mechanism includes a threaded rod and a cone head, wherein the threaded rod is disposed inside the housing, and the cone head is fixedly installed at one end of the threaded rod.

[0007] The bottom of the inner wall of the box is rotatably connected to a threaded tube, and the threaded rod is threaded to the inner wall surface of the threaded tube and passes through the threaded tube and the lower surface of the box. Sliding grooves are provided on both sides of the inner wall of the box.

[0008] The inner wall surface of the chute is slidably connected to a limiting plate, the threaded rod is rotatably connected to the lower surface of the limiting plate, and the threaded tube surface is fixedly fitted with teeth.

[0009] The bottom of the inner wall of the box is rotatably connected to a rotating shaft, a gear is fixedly installed on the surface of the rotating shaft, the gear meshes with the teeth, and a pulley is fixedly installed at one end of the rotating shaft.

[0010] The pulley has a synchronous belt meshing with its outer circumferential surface, a mounting bracket is fixedly installed at the bottom of the inner wall of the housing, a motor is fixedly installed on the upper surface of the mounting bracket, and the output shaft of the motor is fixedly connected to the pulley.

[0011] The shock absorption mechanism includes a connecting plate, which is fixedly mounted on the upper surface of the housing. A damper is fixedly installed on the upper surface of the connecting plate, and a support frame is fixedly installed at one end of the damper.

[0012] A spring is fixedly installed on the upper surface of the connecting plate, and the other end of the spring is fixedly connected to the lower surface of the support frame. A top plate is fixedly installed on the upper surface of the support frame.

[0013] Beneficial effects This application provides a vibration damping support device for an air compressor. It has the following beneficial effects: 1. In this invention, a support mechanism is used to drive a motor-driven gear, pulley, and threaded tube to lift and lower the threaded rod and the cone head. This mechanism can adapt to uneven ground. The cone head can be inserted into the ground to improve grip and effectively prevent equipment from vibrating and shifting, making the equipment more stable.

[0014] 2. In this invention, the shock absorption mechanism adopts a combination structure of spring and damper, which can not only buffer the vibration generated by the operation of the air compressor, but also quickly consume the vibration energy and prevent the continuous transmission of vibration. Combined with a stable support structure, it can achieve the synergistic effect of shock absorption and support, and greatly improve the shock absorption effect and the stability of equipment operation.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] First embodiment: Please refer to Figures 1 to 4This invention provides a vibration damping support device for an air compressor, comprising a housing 1, an internal support mechanism 2 for supporting the device and fixing it to the ground, and a vibration damping mechanism 3 for damping the air compressor above the housing 1. The support mechanism 2 includes a threaded rod 202 and a cone 203. The threaded rod 202 is installed inside the housing 1, and the cone 203 is fixedly installed at one end of the threaded rod 202. The housing 1 adopts a closed rigid shell structure, serving as the core load-bearing base of the entire device, integrating the support mechanism 2 and the vibration damping mechanism 3 into the same structural unit, improving overall compactness and ease of installation. The threaded rod 202, as the core telescopic component of the support mechanism 2, can extend and retract vertically. The cone head 203 adopts a pointed, rigid structure, which can penetrate the ground in complex conditions such as soft soil and gravel surfaces, significantly increasing the gripping force with the ground. This fundamentally solves the problems of device slippage, tilting, and displacement caused by vibration during air compressor operation, improving the stability and safety of the equipment in field and construction environments. A threaded pipe 201 is rotatably connected to the bottom of the inner wall of the housing 1. The threaded rod 202 is threaded to the inner wall surface of the threaded pipe 201 and passes through the threaded pipe 201 and the lower surface of the housing 1. Sliding grooves 204 are provided on both sides of the inner wall of the housing 1. The threaded pipe 201 is rotatably connected to the bottom of the housing 1 through bearings and can rotate stably around its own axis under power drive. The inner wall of the threaded tube 201 and the threaded rod 202 are precisely threaded together. When the threaded tube 201 rotates, the rotational motion is converted into the linear lifting motion of the threaded rod 202 through the thread engagement, achieving precise adjustment of the support height. The threaded rod 202 passes through both the threaded tube 201 and the lower surface of the housing 1, ensuring that the extension direction is always perpendicular to the ground, improving the reliability of the support. The sliding grooves 204 on both sides of the inner wall of the housing 1 extend vertically, providing stable sliding guidance for the internal moving parts, preventing jamming or skew during movement, and ensuring smooth operation of the support mechanism 2. The inner wall surface of the sliding groove 204 is slidably connected to the limiting plate 205, and the threaded rod 202 is rotatably connected to the lower surface of the limiting plate 205. Teeth 206 are fixedly installed on the surface of the threaded tube 201. The two ends of the limiting plate 205 are slidably engaged with the sliding groove 204, allowing it to move smoothly up and down along the sliding groove 204. The top end of the threaded rod 202 is rotatably connected to the limiting plate 205. This allows it to move up and down synchronously with the limiting plate 205 without rotating, effectively restricting the threaded rod 202 from rotating synchronously with the threaded tube 201. This ensures the threaded rod 202 performs only purely linear vertical movements, guaranteeing the cone 203 penetrates the ground vertically and improving the fixing effect. The teeth 206 fixed to the outer wall of the threaded tube 201 are evenly distributed circumferentially for meshing with the transmission to transmit torque, enabling smooth external power to drive the threaded tube 201 to rotate. This results in high overall transmission efficiency and stable operation.A rotating shaft 207 is rotatably connected to the bottom of the inner wall of the housing 1. A gear 208 is fixedly mounted on the surface of the rotating shaft 207, and the gear 208 meshes with the teeth 206. A pulley 209 is fixedly mounted on one end of the rotating shaft 207. The rotating shaft 207 is supported inside the housing 1 by bearings and can rotate flexibly to transmit power. The gear 208 and the teeth 206 on the threaded tube 201 form an external meshing transmission mechanism, which smoothly transmits the rotational power of the rotating shaft 207 to the threaded tube 201, causing the threaded tube 201 to rotate in a set direction. The pulley 209 is coaxially fixed with the rotating shaft 207 and is used to receive the power transmitted by the synchronous belt 210, ensuring stable and reliable power input. This transmission structure can achieve a speed reduction and torque increase effect, so that the threaded rod 202 has sufficient downward pressure when it extends, ensuring that the cone 203 can smoothly penetrate the ground and adapt to ground environments with different hardness. A synchronous belt 210 meshes with the outer circumferential surface of pulley 209. A mounting bracket 211 is fixedly installed at the bottom of the inner wall of housing 1. A motor 212 is fixedly installed on the upper surface of mounting bracket 211, and the output shaft of motor 212 is fixedly connected to pulley 209. Motor 212 serves as the power source for the entire support mechanism 2 and is fixed on mounting bracket 211 to ensure that it does not shake or shift during operation. The output shaft of motor 212 directly drives pulley 209 to rotate, and then transmits power synchronously to other pulleys 209 through synchronous belt 210, realizing the synchronous lifting and lowering of multiple sets of support components, ensuring that the support height of the four corners of the device is consistent, and keeping the air compressor in a horizontal state. Synchronous belt 210 has high transmission precision and does not slip, which can ensure that the multiple sets of support mechanisms 2 move synchronously and are evenly stressed, avoiding tilting and shaking of the device due to uneven stress, and further improving the overall support stability.

[0020] Working principle: Start motor 212, which drives pulley 209 to rotate. Through synchronous belt 210, another set of pulleys 209 and rotating shaft 207 rotate synchronously. Gear 208 rotates with rotating shaft 207 and meshes with teeth 206, driving threaded tube 201 to rotate. Threaded rod 202 rises and falls under the action of the thread in threaded tube 201. Limiting plate 205 slides along slide groove 204 to restrict the rotation of threaded rod 202, ensuring its vertical rise and fall. Cone head 203 extends out of housing 1 with threaded rod 202 and inserts into the ground to achieve fixation. When stopping, start motor 212 in reverse to retract cone head 203.

[0021] Second embodiment: Please refer to Figure 1 and Figure 5This embodiment of the invention provides a vibration damping mechanism 3, including a connecting plate 301. The connecting plate 301 is fixedly installed on the upper surface of the housing 1. A damper 302 is fixedly installed on the upper surface of the connecting plate 301, and a support frame 304 is fixedly installed at one end of the damper 302. The connecting plate 301 serves as the mounting base for the vibration damping mechanism 3, rigidly connected to the upper end of the housing 1, and can evenly transmit the damping force to the housing 1, avoiding local stress concentration. The damper 302 adopts a hydraulic damping structure, the main function of which is to consume the vibration energy generated by the air compressor, quickly suppress the vibration amplitude, avoid the repeated rebound of the spring 303 causing resonance, significantly improve the vibration damping stability and noise reduction effect, and protect the precision components inside the air compressor from vibration damage. The support frame 304 is used to bear the upper load and evenly transmit the vibration to the damper 302 and the spring 303. A spring 303 is fixedly installed on the upper surface of the connecting plate 301, and the other end of the spring 303 is fixedly connected to the lower surface of the support frame 304. A top plate 305 is fixedly installed on the upper surface of the support frame 304. Spring 303, made of high-elasticity alloy, is arranged parallel to damper 302 to form a composite damping structure. Spring 303 primarily buffers and absorbs the vibration impact generated by the air compressor, reducing vibration peaks; it works in conjunction with damper 302 to quickly dissipate energy and prevent continuous oscillation. Top plate 305 is a flat mounting plate used to directly support and fix the air compressor body, increasing the contact area for more uniform pressure distribution, preventing localized deformation of the air compressor, and facilitating rapid installation and positioning of the air compressor, thus improving assembly efficiency.

[0022] Working Principle: The air compressor is fixedly installed on the upper surface of the top plate 305. During operation, the high-frequency, high-intensity vibrations are transmitted from top to bottom to the support frame 304, and then evenly distributed by the support frame 304 to the spring 303 and damper 302 below. The spring 303, under stress, undergoes elastic expansion and contraction, effectively absorbing and buffering the impact load from the air compressor's operation, significantly reducing vibration peaks. Simultaneously, the damper 302 and spring 303 work in sync, rapidly consuming excess kinetic energy generated by vibration through the viscous resistance of the internal damping medium. This effectively prevents the spring 303 from repeatedly rebounding and continuously oscillating due to excessive elasticity, achieving rapid vibration stabilization and resonance suppression. The residual force after dual damping is smoothly transmitted to the housing 1, and then through the support mechanism 2 for stable grip and rigid support, fundamentally blocking further transmission of vibration to the ground. This effectively prevents slippage, displacement, and shaking caused by continuous vibration, while significantly reducing operating noise and improving the overall operational stability and service life of the air compressor.
