Description

Technical Field

[0001] This utility model relates to the field of air flotation platforms, and in particular to an air flotation platform with a stable structure. Background Technology

[0002] An air flotation platform is a suspension system that uses gas as a medium. It utilizes the buoyancy generated by gas flow to support and suspend objects, achieving a contactless suspension effect. The principle is to inject compressed air or nitrogen into a planar interface. The gas flow and bubble formation generate buoyancy to support and suspend the object, forming a gas suspension layer, thereby achieving the suspension of the object and enabling high-precision processing, photolithography, and inspection.

[0003] Existing air-floating platforms are mostly used to carry and transport objects. When an object moves left and right at the top of the air-floating platform, the center of gravity of the device changes rapidly. As a result, the air-floating platform may tilt and sway violently from side to side. When one end tilts excessively, it will come into contact with the track and cause friction, which may damage the track and the platform. Therefore, an air-floating platform with a stable structure is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an air-floating platform with a stable structure, which aims to improve the problem in the prior art that "the left and right movement of heavy objects at the top of the air-floating platform will cause the center of gravity of the air-floating platform to change rapidly, which may cause friction between the platform and the track".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-floating platform with a stable structure, including a support rail, a stabilizing frame slidingly attached to the top of the support rail, an air-floating component disposed at the top of the support rail, the air-floating component including a support platform, the support platform slidingly attached to the top of the support rail, a buffer component disposed at the front end of the support platform, a balancing component disposed at the rear end of the support platform, the buffer component including a rotating shaft, the rear end of the rotating shaft being fixedly connected to the front end of the support platform, and the rotating shaft passing through and rotatably connected to the front end of the stabilizing frame.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the fixed sleeve is provided with a connection port, and the bottom end of the air supply pipe is provided with an air supply port. The connection port and the air outlet are interconnected.

[0012] As a further description of the above technical solution:

[0013] The fixed sleeve is rotatably connected to the rear end of the stabilizing frame, the rear end of the gas supply pipe is fixedly connected to an auxiliary air port, and the front end of the auxiliary air port is fixedly connected to the rear end of the stabilizing frame.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting a buffer component, when the support platform tilts, it will cause the rotating frame to tilt at the same time. By setting a connecting rod, sleeve, piston block, and air hole, the rotation speed of the rotating frame can be reduced, thereby alleviating the rotation of the support platform and preventing it from shaking violently from side to side. The overall device has good stability.

[0022] 2. In this utility model, by setting a balancing component, when a heavy object is placed on one side of the top of the support platform for a long time, the support platform will tilt and drive the fixed sleeve to rotate.

At this time, the gas will enter the interior of the air outlet through the air inlet and the connection port, increasing the air pressure inside the air outlet on one side. This can increase the support capacity on one side of the device, keep the device stable, and improve the overall safety of the device. Attached Figure Description

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of an air-floating platform with a stable structure, including a support rail 1 for supporting the overall device. A stabilizing frame 2 for stabilizing an air-floating component 3 slides at the top of the support rail 1. An air-floating component 3 for carrying and transporting heavy objects is provided at the top of the support rail 1. The air-floating component 3 includes a support platform 31 for directly supporting the heavy objects. The support platform 31 is existing technology; it can be suspended by supplying air to it. Due to its existing nature, this invention will not describe it in detail. The stabilizing frame 2 and the support platform 31 work on the same principle; after being filled with air, they can be suspended at the top of the support rail 1 by the principle of air floating. Since the stabilizing frame 2 does not need to bear heavy objects, it will only move back and forth after it is suspended and will not rotate randomly. The support platform 31 slides on the top of the support track 1. The front end of the support platform 31 is provided with a buffer component 4 to relieve the pressure of heavy objects. The rear end of the support platform 31 is provided with a balancing component 5 to keep the support platform 31 balanced. The buffer component 4 includes a rotating shaft 41 for connecting the support platform 31 and the rotating frame 42. The rear end of the rotating shaft 41 is fixedly connected to the front end of the support platform 31. When the support platform 31 rotates, the rotating shaft 41 will also be driven to rotate synchronously. The rotating shaft 41 passes through and is rotatably connected to the front end of the stabilizing frame 2.

[0031] Reference Figure 2 - Figure 4 The left end of the support platform 31 is fixedly connected to an air inlet 32 ​​for facilitating gas entry into the interior of the support platform 31. The inner wall of the support platform 31 is provided with a main air passage 34 for facilitating gas distribution. The right end of the main air passage 34 is provided with an air outlet 33 for supplying air to the air outlet 37. Near the bottom of the air outlet 33 at the right end of the main air passage 34, an air outlet 35 is provided for blowing air towards the side of the support rail 1 to prevent the side of the support platform 31 from contacting the support rail 1. The bottom end of the main air passage 34 is provided with an air outlet 35 for blowing air towards the side of the support rail 1. The bottom end of the support platform 31 has an air outlet 36 for blowing air, and the bottom end of the air outlet 33 is provided with an air outlet 37 for blowing air to the top of the support rail 1. The reaction force generated by blowing air to the top of the support rail 1 through the air outlet 37 can make the support platform 31 suspend. The balancing component 5 includes a fixing sleeve 53 for sealing the air supply pipe 52. The outer wall of the fixing sleeve 53 is fixedly connected to the inner wall of the support platform 31, and the inner wall of the fixing sleeve 53 is rotatably connected to the air supply pipe 52 for supplying gas to the inside of the support platform 31.

[0032] Reference Figure 2 - Figure 4The outer wall of the fixed sleeve 53 is provided with a connection port 55 for supplying air into the air outlet 33. The bottom end of the air supply pipe 52 is provided with an air inlet 54 for transmitting gas. When the air inlet 54 and the connection port 55 are connected, gas can enter the air outlet 33 from the inside of the air supply pipe 52. The connection port 55 and the air outlet 33 are interconnected. By supplying air into the air outlet 33 through the connection port 55, the single-sided support capacity of the support platform 31 can be increased. The fixed sleeve 53 is rotatably connected to the rear end of the stabilizing frame 2. The rear end of the air supply pipe 52 is fixedly connected with an auxiliary air inlet 51 for supplying air into the air supply pipe 52. The front end of the auxiliary air inlet 51 is fixedly connected to the rear end of the stabilizing frame 2.

[0033] Reference Figure 1 - Figure 3 A rotating frame 42 for moving a slider 43 is fixedly connected to the outer wall of the rotating shaft 41. A slider 43 for moving a connecting rod 44 up and down is slidably connected to the front end of the rotating frame 42. A connecting rod 44 is rotatably connected to the rear end of the slider 43. When the rotating frame 42 rotates about the center line of the rotating shaft 41, it will move the slider 43. When the slider 43 moves, it will move the connecting rod 44 up and down. The connecting rod 44 slides at the bottom end of the rotating frame 42. A piston block 46 for closing the opening of the sleeve 45 is fixedly connected to the bottom end of the connecting rod 44. A storage block 46 is fixedly connected to the front end of the stabilizing frame 2. The sleeve 45 is connected to the piston block 46, which is connected to the inner wall of the sleeve 45. When the connecting rod 44 moves up and down, it will drive the piston block 46 to move up and down on the inner wall of the sleeve 45. The bottom end of the sleeve 45 is provided with an air hole 48 for air to leave the inside of the sleeve 45. The diameter of the air hole 48 is small, so the speed of the gas passing through the air hole 48 is also limited. The bottom end of the piston block 46 is fixedly connected to a return spring 47 for pushing the piston block 46 upward to reset it. The bottom end of the return spring 47 is fixedly connected to the inner wall of the sleeve 45, and the return spring 47 will push the piston block 46 upward at all times.

[0034] Working principle: When the weight moves left and right at the top of the support platform 31, it will squeeze the support platform 31 and make it rotate. The support platform 31 will drive the rotating frame 42 to rotate synchronously through the rotating shaft 41. When the rotating frame 42 rotates, it will drive the slider 43 to move. When the slider 43 moves, it will drive the connecting rod 44 to move up and down. The connecting rod 44 will drive the piston block 46 to move up and down. The piston block 46 will compress the air and make it enter or exit the sleeve 45 through the air hole 48. Since the diameter of the air hole 48 is small, the speed of air movement is also limited, so the speed of piston block 46 is also limited. Thus, the rotation of the support platform 31 is also limited, so it can only rotate at a slower speed. In this way, when the center of gravity of the support platform 31 changes rapidly, the support platform 31 will not shake violently back and forth.

[0035] Meanwhile, when a heavy object is placed on one side of the top of the support platform 31, the support platform 31 will rotate, which will also drive the fixed sleeve 53 to rotate. The rotation of the fixed sleeve 53 will connect the air inlet 54 and the connection port 55. At this time, the gas can enter the interior of the air outlet 33 through the air inlet 54 and the connection port 55, thereby increasing the air pressure inside the air outlet 33. As a result, the gas discharged through the air outlet 37 will also increase, which can increase the support capacity of one side of the support platform 31, thereby preventing the device from tilting too much and keeping the device stable.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
