Description

Technical Field

[0001] This utility model relates to the field of air flotation platforms, and in particular to a multi-axis supported air flotation platform. Background Technology

[0002] An air-floating platform is a platform that uses the principle of air floating to transport objects. Because it uses the principle of air floating for transmission, the coefficient of friction between the overall device and the track is low, and the transmission accuracy is high. Air-floating platforms can be divided into single-axis air-floating platforms and multi-axis air-floating platforms according to the number of support shafts. Multi-axis air-floating platforms are supported by multiple sets of sliding tracks and are often used to move heavier objects.

[0003] When using a multi-axis air-bearing platform to move objects of different weights, it is often necessary to adjust the output air pressure according to the weight of the object. If the air pressure is too high, the air-bearing platform may float too high, and if the air pressure is too low, the air-bearing platform may come into contact with the slide rail and cause friction. Since it requires frequent adjustment, it is quite troublesome to use. Therefore, a multi-axis support air-bearing platform is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-axis supported air flotation platform, which aims to improve the problem in the prior art that "it is inconvenient to use because the air pressure needs to be repeatedly adjusted when moving items of different weights".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-axis supported air flotation platform, including a support slide rail, an air flotation platform slidably mounted on the top of the support slide rail, a support platform slidably connected to the top of the air flotation platform, an air flotation component disposed inside the air flotation platform, a buffer component disposed at the bottom of the support platform, an adjustment component disposed at the front end of the air flotation platform, the air flotation component including an air inlet pipe, the air inlet pipe penetrating and fixedly connected to the left end of the air flotation platform, a main air passage disposed on the inner wall of the air flotation platform, an air outlet disposed at the right end of the main air passage, an exhaust port disposed at the rear end of the air flotation platform, and a buffer groove disposed between the support platform and the top of the air flotation platform.

[0008] As a further description of the above technical solution:

[0009] A buffer spring is fixedly connected to the bottom end of the rubber block, and the bottom end of the buffer spring is fixedly connected to the inner wall of the sleeve.

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

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

[0013] The adjustment component includes an adjustment frame, the rear end of which is fixedly connected to the front end of the air flotation platform, and a baffle is slidably connected to the bottom end of the adjustment frame.

[0019] The adjustment components and exhaust ports are provided in multiple sets, and the multiple sets of adjustment components and exhaust ports are symmetrically arranged with the center line of the air flotation platform as the axis of symmetry.

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

[0021] 1. In this utility model, by setting up a support platform, when the device is unloaded, excess air will enter the buffer tank through the air outlet and be discharged outward through the exhaust port, thereby preventing excessive air pressure inside the device. When the device is carrying heavy objects, the support platform will be squeezed downward by the heavy objects and block the air outlet. In this way, the air can only be discharged through the air flotation port and the stabilization port, which can increase the load-bearing capacity of the device. With this setting, when moving heavy objects, there is no need to repeatedly adjust the air pressure, and the overall device is more convenient to use.

[0022] 2. In this utility model, by setting a buffer component, when the support platform moves downward under the pressure of a heavy object, the buffer component will slow down its descent speed, thus preventing it from being damaged by moving too fast. The overall device has good stability during use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of a multi-axis supported air flotation platform, including a support slide rail 1 for supporting the overall device, an air flotation platform 2 for supporting a support platform 4 slidably mounted on the top of the support slide rail 1, a support platform 4 for supporting heavy objects slidably connected to the top of the air flotation platform 2, an air flotation component 3 for driving gas flow inside the air flotation platform 2, a buffer component 6 for protecting the air flotation platform 2 at the bottom of the support platform 4, and an adjustment component 5 for adjusting the supporting capacity of the air flotation component 3 at the front end of the air flotation platform 2. The air flotation component 3 includes an inlet for allowing high-pressure gas to enter the interior of the air flotation platform 2. The air inlet pipe 31 is connected to the left end of the air flotation platform 2. The inner wall of the air flotation platform 2 is provided with a main air passage 32 for gas to flow inside the air flotation platform 2. The right end of the main air passage 32 is provided with an outlet 33 for discharging excess gas. The rear end of the air flotation platform 2 is provided with an exhaust port 34 for discharging gas. A buffer groove 37 is provided between the support platform 4 and the top of the air flotation platform 2. When the air pressure inside the main air passage 32 is too high, the excess gas will enter the interior of the buffer groove 37 through the outlet 33 and leave the buffer groove 37 through the exhaust port 34. This can prevent the air pressure inside the device from being too high.

[0031] Reference Figure 1 - Figure 3 The buffer assembly 6 includes a slider 61 for connecting to the support platform 4. A rubber block 62 for reducing the moving speed of the slider 61 is fixedly connected to the bottom end of the slider 61. A sleeve 64 for accommodating the slider 61 is sleeved on the outer wall of the slider 61. The bottom end of the sleeve 64 is fixedly connected to the top end of the air-floating platform 2. When the support platform 4 moves downward, it will drive the slider 61 and the rubber block 62 to move into the sleeve 64. At the same time, the outer wall of the rubber block 62 will squeeze the inner wall of the sleeve 64 to reduce the moving speed of the slider 61. A buffer spring 63 for pushing the rubber block 62 to move upward and reset is fixedly connected to the bottom end of the rubber block 62. The bottom end of the buffer spring 63 is fixedly connected to the inner wall of the sleeve 64. The buffer spring 63 will push the rubber block 62 upward at all times.

[0032] Reference Figure 2 - Figure 4The bottom end of the main air duct 32 is provided with an air flotation port 35 for gas discharge. After the gas is discharged through the air flotation port 35, a gas suspension layer is formed, which can push the air flotation platform 2 to suspend it. The right end of the main air duct 32 is provided with a stabilizing port 36 for pushing the air flotation platform 2 to prevent it from swaying left and right. The adjustment component 5 includes an adjustment frame 51 for supporting the baffle 52. The rear end of the adjustment frame 51 is fixedly connected to the front end of the air flotation platform 2. The bottom end of the adjustment frame 51 is slidably connected with a baffle 52 for blocking the exhaust port 34. The baffle 52 is used to block the exhaust. The air vent 34 prevents gas from escaping from the buffer tank 37. When it is necessary to support heavy objects for a long time, the air vent 34 can be closed, so that the gas can only be discharged out through the air flotation port 35 and the stabilization port 36. This allows the device to maintain a high support force. The left end of the baffle 52 is slidably connected to a locking block 53 for fixing the baffle 52. The inner wall of the adjusting frame 51 is provided with a groove 55 for accommodating the locking block 53. The groove 55 and the locking block 53 are compatible. When the locking block 53 is inserted into the groove 55, the baffle 52 will be fixed and cannot move up or down.

[0033] Reference Figure 2 - Figure 4 Multiple sets of locking blocks 53 are provided, and the multiple sets of locking blocks 53 are symmetrically arranged with the center line of the adjustment frame 51 as the axis of symmetry. The multiple sets of locking blocks 53 can fix the baffle 52 from both sides at the same time. The right end of the locking block 53 is fixedly connected to an adjustment spring 54 for pushing the locking block 53 outward. The right end of the adjustment spring 54 is fixedly connected to the left end of another set of locking blocks 53. The adjustment spring 54 will push the locking block 53 outward at all times. Multiple sets of adjustment components 5 and exhaust ports 34 are provided, and the multiple sets of adjustment components 5 and exhaust ports 34 are symmetrically arranged with the center line of the air flotation platform 2 as the axis of symmetry. The exhaust ports 34 are provided on both sides of the device to ensure uniform exhaust of the device. When closing the exhaust ports 34, the adjustment components 5 on both sides need to be completely closed.

[0034] Working principle: When the device moves a heavy object, when the object is placed on top of the support platform 4, the support platform 4 will move downwards under the pressure of the object. This downward movement of the support platform 4 will block the air outlet 33 and exhaust port 34, causing the air pressure inside the buffer tank 37 to rise. As a result, after the gas enters the main air passage 32, more gas will be discharged outwards through the air flotation port 35 and stabilization port 36. The air pressure between the air flotation platform 2 and the support rail 1 will increase, giving the device stronger support. This prevents the air flotation platform 2 from colliding with the support rail. 1. Contact wear: When the heavy object is removed, the buffer spring 63 will push the rubber block 62 upward, causing the slider 61 to move upward. The upward movement of the slider 61 will push the support platform 4 to move upward and reset. At this time, the air outlet 33 and the exhaust port 34 will no longer be blocked, and the air pressure inside the buffer groove 37 will be restored. In this way, excess gas can be discharged outward through the air outlet 33 and the exhaust port 34. This can prevent the air pressure between the air floating platform 2 and the support slide rail 1 from being too high. The whole device can automatically adapt to the heavy object without the need for manual adjustment of the air pressure, which is more convenient to use.

[0035] 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.
