Description

Technical Field

[0001] The present invention relates to the field of air compressor accessories, and particularly to an installation base for an air compressor. Background Art

[0002] An air compressor is a gas source component that uses electric power to drive the movement of mechanical components and stores the generated gas in a gas tank. During its operation, vibrations are generated due to the movement of the mechanical components. If it is rigidly fixed, the vibrations cannot be effectively released, easily causing damage to mechanical parts and generating noise. Secondly, a large amount of heat is generated during the movement of the mechanical components and the compression of the gas, so a corresponding radiator needs to be equipped. The existing radiators have a relatively simple structure, mostly using a cooling fan for direct heat dissipation, with poor heat exchange capacity, and sometimes it is difficult to meet the working requirements of high-load air compressors. Summary of the Invention

[0003] The purpose of the present invention is to provide an installation base for an air compressor to solve the problems mentioned in the above background art.

At the four corners and the center of the bottom of the mounting plate, support rods are provided. Circular openings for the support rods to pass through are formed on the fixing plate. A horizontal buffer device is arranged on the outer side of the support rods. The horizontal buffer device is arranged on the fixing plate and is used to absorb the vibrations in the horizontal direction of the support rods. The downward vibration impact force of the support rods acts on the support plate. A heat dissipation device is arranged at the bottom of the bottom plate. A plurality of vertical buffer devices are also arranged between the support plate and the bottom plate. When absorbing the vibrations in the vertical direction, the vertical buffer devices can also drive the circulation of the cooling medium in the heat dissipation device.

[0024] As Figures 1 to 5 shown, an installation base of an air compressor includes a base plate 1. Above the base plate 1, a support plate 2, a fixed plate 3 and a mounting plate 4 are successively arranged from low to high. The mounting plate 4 is used to directly fix the air compressor. At the four corners and the center of the bottom of the mounting plate 4, support rods 41 are provided. A round opening 31 for the support rods 41 to pass through is formed on the fixed plate 3. The diameter of the round opening 31 is larger than that of the support rods 41 to reserve space for the movement of the support rods 41. A horizontal buffer device 5 is arranged outside the support rods 41. The horizontal buffer device 5 is arranged on the fixed plate 3 and is used to absorb the vibration in the horizontal direction of the support rods 41. The downward vibration impact force of the support rods 41 acts on the support plate 2. A heat dissipation device 6 is arranged at the bottom of the base plate 1. A plurality of vertical buffer devices 7 are further arranged between the support plate 2 and the base plate 1. When absorbing the vibration in the vertical direction, the vertical buffer devices 7 can also drive the circulation of the cooling medium in the heat dissipation device 6.

[0025] In this embodiment, the horizontal buffer device 5 includes an outer frame 51 and buffer columns 52. A plurality of buffer columns 52 are equidistantly arranged around the support rod 41, and the axes of the buffer columns 52 all point to the axis center of the support rod 41. A first baffle 521 and balls 522 in contact with the support rod 41 are provided at the inner ends of the buffer columns 52, and a second baffle 523 is provided at the outer ends thereof. A first spring 53 is provided between the first baffle 521 and the outer frame 51. When the support rod 41 moves towards the buffer columns 52, the first baffle 521 is used to compress the first spring 53 to provide buffering.

[0026] In this embodiment, the fixing plate 3 is fixedly connected to the bottom plate 1 through a fixing rod 9. The support plate 2 is slidably connected to the fixing rod 9, and a second spring 10 is sleeved on the fixing rod 9 between the support plate 2 and the bottom plate 1. The second spring 10 is used to provide support for the support plate 2.

[0027] In this embodiment, a universal ball is provided at the bottom of the support rod 41. A bowl-shaped support block 54 is provided below the universal ball. The support block 54 is fixedly connected to the support plate 2. The universal ball slides within the support block 54. The lowest point of the support block 54 is at the center, which can prompt the support rod 41 to quickly reset to the center. Universal wheels 11 with brakes are further provided at the four corners of the bottom of the bottom plate 1. The universal wheels 11 are used to move the base.

[0028] In this embodiment, the heat dissipation device 6 includes a liquid storage plate 61 and cooling pipes. The interior of the liquid storage plate 61 is hollow and filled with a coolant. The inlet of the liquid storage plate 61 is connected to the outlet of the cooling pipes. The cooling pipes are in contact with the heat source components of the air compressor for heat exchange. Heat dissipation fins 62 are provided on the bottom plate 1 of the liquid storage plate 61. A heat dissipation fan 63 is provided on one side in the extending direction of the heat dissipation fins 62. The wind direction of the heat dissipation fan 63 is the same as the extending direction of the heat dissipation fins 62, which is convenient for air flow to circulate between the heat dissipation fins 62.

[0029] In this embodiment, the vertical buffer device 7 includes a buffer cylinder 71 and a pressing rod 72. The buffer cylinder 71 is fixedly connected to the bottom plate 1. A piston 73 is slidably connected within the buffer cylinder 71. The piston 73 is fixedly connected to the pressing rod 72. A liquid outlet channel 721 is provided within the piston 73 and the pressing rod 72.

The first round bead 74 and the second round bead 75 sink within the corresponding tapered hole one and tapered hole two under the action of gravity, so that the liquid direction is from bottom to top.

[0030] In this embodiment, a liquid outlet pipe 722 communicating with the liquid outlet channel 721 is further provided on the pressing rod 72. The liquid outlet pipe 722 is communicated with the inlet of the cooling pipeline. A cover 76 blocking the liquid outlet channel 721 is provided at the top of the pressing rod 72. The cover 76 is fixedly connected to the support plate 2. A baffle 77 is provided on the inner bottom surface of the buffer cylinder 71. A third spring 78 is provided between the piston 73 and the baffle 77. A round hole 771 concentric with the liquid inlet channel 711 is provided on the baffle 77. The diameter of the round hole 771 is smaller than that of the second ball 75. The baffle 77 can limit the second ball 75 within the liquid inlet channel 711.

[0031] Working process and principle:

[0032] The air compressor is installed and fixed on the top of the mounting plate 4. The support plate 2 is supported by the second spring 10 and the pressing rod 72. The support block 54 on the support plate 2 provides support for the support rod 41.

[0033] When the air compressor vibrates, there are two component forces of the vibration force in the horizontal and vertical directions. The vibration component force in the horizontal direction acts on the mounting plate 4. The mounting plate 4 can move arbitrarily in the horizontal direction. The support rod 41 plays a supporting role for the mounting plate 4. When the mounting plate 4 moves, the support rod 41 moves around in the middle of the buffer column 52. The universal ball rolls within the support block 54 to reduce the friction force of the hard contact between the support rod 41 and the support block 54. When the support rod 41 moves towards one or more buffer columns 52, the first spring 53 on the corresponding buffer column 52 is compressed, and the first spring 53 on the buffer column 52 in the opposite direction is decompressed, so that the buffer column 52 is always in contact with the support column, thereby using the buffer force of the first spring 53 to absorb the vibration force in any direction on the horizontal plane of the support column.

[0034] At the same time, since the central position of the support block 54 is the lowest, when the support rod 41 moves in any direction around, it climbs upward along the support block 54, so that a part of the vibration is converted into gravitational potential energy. At the same time, the curved surface can also accelerate the support rod 41 to return to the lowest point, that is, the central position, to achieve rapid reset.

[0035] When the vertical vibration component acts on the mounting plate 4, if the component force is downward, the support rod 41 can press down the support block 54, causing the support plate 2 to move downward, driving the downward pressure rod 72 to move downward, the piston 73 to move downward, and the second ball 75 to block the second tapered hole of the liquid inlet channel 711 under the action of gravity. The coolant in the compressed buffer cylinder 71 cavity will push up the first ball 74, causing the cooling medium in the buffer cylinder 71 to be injected into the cooling pipe, and pushing the hot coolant in the cooling pipe to flow back into the liquid storage plate 61. When the vibration component force is upward, the third spring 78 and the second spring 10 are decompressed, causing the support plate 2 to move upward and the downward pressure rod 72 to move upward. If there is liquid flowing downward from the liquid outlet channel 721, it will push the first ball 74 against the first tapered hole. At the same time, the first ball 74 is also affected by gravity, and the liquid outlet channel 721 is blocked. The coolant in the liquid storage plate 61 enters the buffer cylinder 71 through the liquid inlet channel 711 to achieve liquid absorption. By repeating this cycle, the flow cycle of the cooling medium in the cooling pipe can be realized.

[0036] The liquid storage plate 61 has a large area and a thin inner cavity. The heat of the coolant from the cooling pipe can be quickly cooled by the heat sink 62 in cooperation with the cooling fan 63. At the same time, the movement of the coolant in the buffer cylinder 71 can also absorb part of the vibration.

[0037] Thus, a series of buffer structures can be used to absorb vibrations in any direction, and part of the vibrations can be used to provide power for the flow of the cooling medium.

[0038] As is known by technical common sense, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.
