Description

Technical Field

[0001] This invention relates to the field of air compressor vibration reduction technology, specifically a mobile air compressor based on a noise reduction and vibration reduction structure. Background Technology

[0002] An air compressor is a device used to compress gas. It is a common power device that converts mechanical energy into gas pressure energy. The main function of an air compressor is to supply gas and provide the gas required for production.

[0003] A typical mobile air compressor includes an air compressor body, a power source for driving the air compressor body, and an air tank for storing compressed gas. In use, first install the casters under the air tank, then fix a support plate on the top of the air tank. On the support plate, the power source, air compressor body, and transmission components for transmitting power are fixed to the support plate with bolts and nuts.

[0004] As human usage requirements become increasingly stringent, support plates with built-in shock absorbers have appeared on the market. Existing shock absorbers typically only come with a single shock-absorbing spring. When a single shock-absorbing spring breaks and fails, the entire shock absorption system will completely fail. Moreover, during continuous use, the internal mechanical transmission components of an air compressor have a high demand for lubricating oil. In the market, the consumption value of lubricating oil is usually judged by manually observing the oil column, which cannot supply oil to the air compressor body in a timely manner. This leads to dry friction and wear between components, resulting in increased vibration amplitude, increased noise, and even permanent damage to components.

[0005] To address the aforementioned issues, improvements to the existing equipment are necessary. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 8 The present invention provides a technical solution: a mobile air compressor based on a noise reduction and vibration damping structure, comprising an air tank 1, a magnetic plate 2, a vibration damping mechanism 3, and an air compressor body 5; the lower end of the air tank 1 is provided with rollers for moving the air tank 1, the magnetic plate 2 is fixedly installed on the air tank 1, the vibration damping mechanism 3 is disposed above the magnetic plate 2, and the air compressor body 5 is disposed above the vibration damping mechanism 3;

[0030] The damping mechanism 3 includes a vertical damping component 6, an auxiliary oil supply component 7, and a horizontal damping component 8. The auxiliary oil supply component 7 is used to intermittently supply oil to the mechanical transmission components inside the air compressor body 5.

[0031] It should be explained that the air compressor body 5 in this application includes a drive source air compressor mechanical transmission mechanism. The electric drive source transmits power to the air compressor mechanical transmission mechanism to complete the periodic air compression and enable the compressed air to be transported to the air storage tank 1 through the connecting pipe.

[0032] In addition, a pressure gauge is installed on the gas storage tank 1 to facilitate staff monitoring the condition inside the tank.

[0033] In a preferred embodiment, an inner limiting chamber 21 is movably provided on the upper surface of the magnetic plate 2. The inner limiting chamber 21 is configured as a rectangular box structure. A support plate 22 is slidably contacted on the inner wall of the inner limiting chamber 21. The upper surface of the support plate 22 is fixedly connected to the air compressor body 5. Multiple vertical shock absorbers 6 are provided, all of which are disposed between the support plate 22 and the lower inner wall of the inner limiting chamber 21.

[0034] In other words, the vertical vibration generated by the air compressor body 5 will cause the support plate 22 to move up and down within the inner limiting chamber 21, and the energy will be dissipated by the vertical damping component 6.

[0035] In a preferred embodiment, an outer limiting frame 23 is fixed on the upper surface of the magnetic plate 2. The outer limiting frame 23 is disposed around the inner limiting frame 21. The outer limiting frame 23 is configured as a rectangle. At least four horizontal shock absorbers 8 are disposed between the inner limiting chamber 21 and the outer limiting frame 23, and the horizontal shock absorbers 8 are symmetrically distributed in pairs.

[0036] It should be explained that the inner limiting chamber 21 is made of carbon steel, which has strong magnetic attraction properties. In other words, the inner limiting chamber 21 can only move in the horizontal plane to avoid vibration causing the inner limiting chamber 21 to detach from the magnetic plate 2.

[0037] The horizontal vibration generated by the air compressor body 5 is dissipated by the horizontal damping component 8.

[0038] In a preferred embodiment, the vertical shock absorber 6 includes an air cylinder 61, a slide rod 62, and a spring 63; the air cylinder 61 is fixed on the lower inner wall of the inner limiting chamber 21, the slide rod 62 is slidably disposed inside the air cylinder 61 and is fixed to the support plate 22, and the spring 63 is connected between the support plate 22 and the air cylinder 61.

[0039] The vertical vibration generated by the air compressor body 5 can be dissipated by multiple springs 63, thus achieving a vibration reduction effect.

[0040] In a preferred embodiment, the auxiliary oil supply assembly 7 includes an oil storage box 71, a first air inlet pipe 72, a second air inlet pipe 73, a guide pipe 74, and an oil guide hose 75. The oil storage box 71 is fixed to the lower inner wall of the inner limiting chamber 21. A sliding groove 711 is provided in the side wall of the oil storage box 71. One end of the first air inlet pipe 72 is connected to one end of a plurality of air cylinders 61, and the other end of the first air inlet pipe 72 is connected to the sliding groove 711. One end of the second air inlet pipe 73 is connected to the other end of the plurality of air cylinders 61, and the other end of the second air inlet pipe 73 is connected to the inside of the oil storage box 71. The lower end of the guide pipe 74 is fixed to the upper end of the oil storage box 71 and is connected to the inside of the oil storage box 71. The upper end of the guide pipe 74 slides through the support plate 22. An oil inlet 51 is provided on the air compressor body 5. One end of the oil guide hose 75 is connected to the upper end of the guide pipe 74, and the other end is connected to the oil inlet 51.

[0041] In a preferred embodiment, the auxiliary oil supply assembly 7 further includes a plug 76, which is slidably disposed in a slide groove 711; a rack 77, which is fixed to the upper end of the plug 76; a spring 78, which is connected between the plug 76 and the lower inner wall of the slide groove 711; a rotating shaft 79, which is rotatably disposed through the upper wall of the oil reservoir 71; a gear 701, which is fixed to one end of the rotating shaft 79 and rotatably disposed in the slide groove 711; the rack 77 and the gear 701 intermittently mesh; a ball valve 702, which is fixed to the other end of the rotating shaft 79 and rotatably disposed in a guide pipe 74; and a piston disc 703, which is slidably disposed in the oil reservoir 71, and the space below the piston disc 703 is connected to the second air intake pipe 73.

[0042] It should be explained that the piston disc 703 contains lubricating oil for lubricating the mechanical transmission components in the air compressor body 5.

[0043] Please refer to details. Figures 4 to 7 Firstly, if one of the springs 78 and 63 breaks, the other can still ensure basic buffering function and prevent complete failure of the vertical buffering function. Secondly, when the air compressor body 5 vibrates vertically and the support plate 22 moves downward, the slide rod 62 moves downward, and some gas will enter the slide groove 711 below the block 76 through the first intake pipe 72, which can overcome the damping effect of the spring 78 and push the block 76 and the rack 77 to move upward synchronously. The other part of the gas will enter the space below the piston disc 703 through the second intake pipe 73, so that the piston disc 703 provides a certain pressure to the lubricating oil above it, so as to facilitate the oil supply work described later.

[0044] If the vibration generated by the air compressor body 5 is too strong, that is, when the support plate 22 pushes the slide bar 62 down too much, the rack 77 will mesh with the gear 701. The gear 701 will drive the ball valve 702 to rotate a certain angle through the rotating shaft 79, that is, the ball valve 702 will open. The lubricating oil in the oil reservoir 71 will flow through the guide pipe 74 and the oil guide hose 75 into the oil inlet 51, thereby lubricating the mechanical transmission components inside the air compressor body 5, thus reducing the vibration amplitude.

[0045] When the air compressor body 5 vibrates vertically and causes the support plate 22 to move upward, the rack 77 will mesh with the gear 701 in the opposite direction again, thereby closing the ball valve 702 and avoiding excessive waste of lubricating oil.

[0046] It should be noted that the meshing process between rack 77 and gear 701 is intermittent, that is, it only occurs occasionally, and the consumption of lubricating oil is negligible. Therefore, lubricating oil can be dripped into the rack 77 and gear 701 during installation, and there is no need to consider the step of dripping lubricating oil into the rack 77 and gear 701 during the operation of the air compressor body 5.

[0047] In a preferred embodiment, an oil filling hole is provided on the side wall of the oil storage box 71, and the oil filling hole is connected to the external oil supply equipment by an oil supply hose 10, which is installed through the support plate 22.

[0048] In other words, when the amount of lubricating oil in the oil reservoir 71 is critically low, the external oil supply device is activated to supply lubricating oil to the oil reservoir 71, ensuring that the auxiliary oil supply component 7 can operate normally.

[0049] In a preferred embodiment, the horizontal shock absorber 8 includes a second air cylinder 91, a second slide rod 92, a third spring 93, a first check valve 94, a second check valve 95, and an air supply hose 96. The second air cylinder 91 is fixed on the inner wall of the outer limiting frame 23. The second slide rod 92 is slidably disposed inside the second air cylinder 91. The third spring 93 is connected between the outer wall of the inner limiting chamber 21 and the second air cylinder 91. An air inlet 911 and an exhaust 912 are provided on the side wall of the second air cylinder 91. The first check valve 94 is sealed and installed in the air inlet 911. The second check valve 95 is sealed and installed in the exhaust 912. One end of the air supply hose 96 is connected to the exhaust 912, and the other end passes through the magnetic plate 2 and is connected to the air storage tank 1.

[0050] It should be noted that you should refer to [link / reference]. Figure 8 The conduction direction of check valve 1 94 is downward, and the conduction direction of check valve 2 95 is downward.

[0051] Please refer to details. Figure 4 and Figure 8First, if spring 3 93 breaks and fails, the sealed air between air cylinder 2 91 and slide rod 2 92 can ensure basic buffering effect and prevent the vertical buffering function from completely failing. Second, when the air compressor body 5 vibrates horizontally and the support plate 22 moves to the left, slide rod 2 92 moves to the left, and the air pressure between air cylinder 2 91 and slide rod 2 92 increases. When the air pressure between air cylinder 2 91 and slide rod 2 92 exceeds the air pressure in the air storage tank 1, the compressed gas between air cylinder 2 91 and slide rod 2 92 will enter the air storage tank 1 through the air supply hose 96. Therefore, the vibration power is used to compress and store the air, which accelerates the storage efficiency in the air storage tank 1.

[0052] When the air compressor body 5 vibrates horizontally and causes the support plate 22 to move to the right, the one-way valve 2 95 closes and the one-way valve 1 94 opens, allowing outside gas to enter the air cylinder 2 91 so as to repeatedly fill the air tank 1.

[0053] The working process of this mobile air compressor based on a noise reduction and vibration damping structure is as follows: First, the drive source inside the air compressor body 5 is started to begin air compression. The vertical damping component 6 and the horizontal damping component 8 can dissipate the energy of the vibration generated by the air compressor body 5. When the air compressor body 5 has been working for a period of time, dry friction occurs inside the air compressor body 5, causing the vibration generated by direct contact of the components to intensify and accompanied by greater noise. The auxiliary oil supply component 7 uses the amplitude change generated by the vertical damping component 6 to supply oil in time. Therefore, it can quickly replenish the lubricating oil, prevent serious damage to the mechanical transmission components inside the air compressor body 5, and at the same time reduce the vibration amplitude and reduce the noise level.

[0054] In summary, this mobile air compressor based on a noise reduction and vibration damping structure achieves the goal of automatically and promptly replenishing lubricating oil, thus meeting people's usage needs.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
