[0033] As attached Figure 1 To be continued Figure 5 The present invention discloses a controllable rotation angle air-floating platform transportation device, including a positioning component 1, a rotation adjustment component 2 and a buffer component 3. The rotation adjustment component 2 is assembled on the top of the positioning component 1, and the buffer component 3 is installed on the top of the rotation adjustment component 2.

[0034] Example 1

[0035] Specifically, the positioning component 1 includes a base 11, a connecting block 12, a sleeve 13, a threaded rod 14, and a support plate 15. The connecting block 12 is symmetrically arranged at both ends of the base 11, and its function is to provide a stable installation support point for the sleeve 13, ensuring the firmness of the connection between the sleeve 13 and the base 11. The sleeve 13 is fixedly connected through the middle of the connecting block 12, and its function is to form a threaded engagement with the threaded rod 14, providing guidance and support for the lifting and lowering adjustment of the threaded rod 14.

[0036] The threaded rod 14 is threaded inside the sleeve 13. Its function is to move up and down by rotating and adjusting, thereby driving the support plate 15 to rise and fall, so as to adapt to different ground heights or to fix the device in place. The support plate 15 is fixedly connected to the bottom end of the threaded rod 14. Its function is to contact the ground, increase the contact area between the device and the ground, and improve the stability of the device when it is placed.

[0037] Example 2

[0038] Based on Example 1, in order to further achieve precise positioning of the rotation angle, a rotation adjustment component is provided at the top of the positioning component.

[0039] Specifically, the rotation adjustment assembly 2 includes a mounting plate 21, a baffle 22, a rotating shaft 23, a guide ring 24, a fixing block 25, a sleeve 26, a connecting plate 27, a support frame, a pressing plate 28, a limiting post 29, a damping element 210, and a spring 211. The mounting plate 21 is located at the top of the base 11 and its function is to provide a mounting carrier for the buffer assembly 3 and the baffle 22, while driving the upper components to rotate and adjust. The baffle 22 is symmetrically arranged at the top of the mounting plate 21 and its function is to limit the items placed on the placement plate 31 to prevent the items from shifting and falling during transportation or rotation.

[0040] The rotating shaft 23 is located at the bottom of the mounting plate 21 and is rotatably connected to the top of the base 11. Its function is to provide a fulcrum for the rotation of the mounting plate 21, ensuring that the mounting plate 21 can rotate flexibly and stably. The fixing block 25 is symmetrically arranged on the bottom of the mounting plate 21 away from the rotating shaft 23. Its function is to fix the guide ring 24 so that the guide ring 24 moves synchronously with the mounting plate 21. The guide ring 24 is arranged through the middle of the fixing block 25. Its function is to achieve precise positioning of the rotation angle by cooperating with the limiting post 29 through the opening limiting groove.

[0041] In addition, sleeve 26 is symmetrically arranged at the outer end of guide ring 24. Its function is to provide installation support for support frame and guide the movement of limit post 29. Connecting plate 27 is arranged at the bottom end of sleeve 26. The bottom end of connecting plate 27 is fixedly connected to the top end of base 11. Its function is to firmly fix sleeve 26 on base 11 and ensure the stability of the overall structure of rotary adjustment assembly. Support frame is arranged at one end of sleeve 26. Its function is to provide installation space and support for pressing plate 28, damping 210 and spring 211.

[0042] Furthermore, the pressing plate 28 is located inside the support frame, and its function is to drive the limiting post 29 to move telescopically, thereby separating or engaging the limiting post 29 with the limiting groove of the guide ring 24. The limiting post 29 is located at one end of the pressing plate 28, and the limiting post 29 is adapted to the limiting groove of the guide ring 24. Its function is to accurately fix the rotation angle of the mounting plate 21 by engaging different limiting grooves of the guide ring 24. The damper 210 is located at the other end of the pressing plate 28, and one end of the damper 210 is fixedly connected to the inner wall of the support frame. Its function is to slow down the moving speed of the pressing plate 28, avoid violent collision between the limiting post 29 and the guide ring 24, and improve the stability after the limiting is fixed. The spring 211 is sleeved on the outer end of the damper 210. Its function is to provide elastic restoring force for the pressing plate 28, ensuring that the limiting post 29 can be stably engaged in the limiting groove of the guide ring 24, thereby enhancing the limiting effect.

[0043] Specifically, the buffer assembly 3 includes a placement plate 31, a second damper 32, and a second spring 33. The placement plate 31 is located at the top of the mounting plate 21 and its function is to directly support the items to be transported and provide a placement surface for the items. The second damper 32 is fixedly connected to the bottom end of the placement plate 31, and the bottom end of the second damper 32 is fixedly connected to the top end of the mounting plate 21. Its function is to absorb the vibration energy generated during transportation and slow down the vibration transmission speed. The second spring 33 is sleeved on the outer end of the second damper 32. Its function is to cooperate with the second damper 32 to form a double buffer structure, further enhance the buffering effect, and effectively protect the items placed on the placement plate 31 from vibration damage.

[0044] The support plate 15 is equipped with an anti-slip rubber pad at its bottom. The surface of the anti-slip rubber pad has staggered anti-slip patterns. The anti-slip rubber pad is fixedly connected to the support plate 15 through a vulcanization process. Its function is to increase the friction between the support plate 15 and the ground, prevent the device from sliding during placement or transportation, and at the same time play a certain buffering role to reduce the impact of uneven ground on the stability of the device.

[0045] In addition, the inner wall of the limiting groove of the guide ring 24 is provided with a wear-resistant coating, which is a ceramic matrix composite coating. Its function is to improve the wear resistance of the inner wall of the limiting groove, reduce the frictional loss between the limiting post 29 and the limiting groove, extend the service life of the guide ring 24 and the limiting post 29, and ensure the long-term stability of the accuracy of the rotation angle positioning.

[0046] It should also be noted that the air flotation platform in this application can be a precision instrument air flotation transport platform, a heavy industrial equipment air flotation transport platform, a logistics and warehousing turnover air flotation transport platform, etc. Figure 1 In this embodiment, an air flotation platform is used as an example of a precision instrument air flotation transport platform. Of course, other types of air flotation platforms can also adopt a similar structure, which will not be described in detail below.

[0047] Understandable Figure 1 The diagram only schematically illustrates some of the components included in the transport device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 The limitations mean that the transport device can also include, compared to Figure 1 More or fewer parts.

[0048] In practical use, the threaded rod 14 in the rotating positioning component 1 is rotated first. The threaded engagement between the threaded rod 14 and the sleeve 13 drives the support plate 15 to move up and down, adjusting the device to a suitable height and making the anti-slip rubber pad at the bottom of the support plate 15 in close contact with the ground, thereby fixing the device in place. The anti-slip texture on the surface of the anti-slip rubber pad increases the friction with the ground, preventing the device from shifting.

[0049] When the rotation angle needs to be adjusted, pull the pressing plate 28 outward. The pressing plate 28 compresses the damper 210 and the spring 211, causing the limiting post 29 to move out of the limiting groove of the guide ring 24, thus releasing the limiting fixation of the guide ring 24. Then, with the pivot 23 as the fulcrum, rotate the mounting plate 21. The mounting plate 21 drives the buffer assembly 3 at the top and the items on the placement plate 31 to rotate synchronously. At the same time, the fixing block 25 at the bottom of the mounting plate 21 drives the guide ring 24 to move along the inner side of the sleeve 26. When the desired angle is reached, release the pressing plate 28. Under the elastic restoring force of the spring 211, the pressing plate 28 drives the limiting post 29 to reset and lock into the corresponding limiting groove of the guide ring 24. The damper 210 slows down the reset speed to avoid violent collisions and achieve precise fixation of the rotation angle.

[0050] During transportation, the vibration generated by the items placed on the placement plate 31 will be transmitted through the placement plate 31 to the damper 32 and spring 33 in the buffer assembly 3. The damper 32 absorbs the vibration energy and slows down the vibration transmission speed, while the spring 33 undergoes elastic deformation to further buffer the vibration. The double buffering effect effectively reduces the impact of vibration on the items and protects the items from damage.

[0051] 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.
