Description

Technical Field

[0001] The utility model relates to the technical field of vibration isolation, in particular to a cradle type vibration isolation platform. Background Art

[0002] The vibration isolator is an elastic element connecting the equipment and the foundation, which is used to reduce and eliminate the vibration force transmitted from the equipment to the foundation and the vibration transmitted from the foundation to the equipment. The air spring vibration isolator installed under the equipment can reduce the impact of the equipment vibration on the external environment. When the equipment payload vibrates in the horizontal direction, its center of gravity is higher than the elastic plane of the vibration isolator, which will cause swaying. The cradle-type vibration isolation platform can lower the support surface of the support platform below the support surface of the air spring, thereby reducing the swaying instability of the equipment during vibration isolation support.

[0003] For example, a cradle-type vibration isolation platform disclosed in the utility model with authorization announcement number CN219529694U adopts air springs for vibration isolation. A corner plate is fixedly arranged on the top of the air spring, a support column is fixedly arranged on the bottom of the air spring, and a support platform is fixedly installed on the bottom of the corner plate. The corner plate cooperates with the support column to lower the support surface of the support platform below the support surface of the air spring, thereby lowering the center of gravity of the equipment after support.

[0004] This prior art also has the following problems when used:

[0005] The positions of the support platform and the angle plate of the device are relatively fixed, and it is difficult to adjust the height of the support platform during use, and the applicability is poor. The vibration generated by the operation of the equipment of the device is mostly eliminated by the air spring and then transmitted to the support column, and then transmitted to the ground by the support column. Since the adjusting bolt is threadedly connected to the support base, when the vibration that is not eliminated by the air spring is transmitted from the support column to the support base, the connection part between the adjusting bolt and the support base will be vibrated, thereby accelerating the wear of the adjusting bolt and the support base and reducing the service life.

[0024] Example

[0025] Please refer to Figure 1-Figure 3 As shown, the utility model provides a cradle-type vibration isolation platform, including a base plate 1, an air spring 5 and a support plate 8. A support plate 8 and four groups of air springs 5 ​​are arranged above the base plate 1. The support plate 8 is used to place equipment. The air spring 5 can be used as a vibration isolation platform of the vibration isolation structure. A horizontal plate 7 is fixedly arranged on the top of the air spring 5, a support column 6 is fixedly arranged on the bottom of the air spring 5, a vertical plate 4 is fixedly arranged on the inner side of the horizontal plate 7, and reinforcing plates are fixedly arranged on the outer side of the vertical plate 4 and the bottom surface of the horizontal plate 7. The reinforcing plate can improve the stability and structural strength of the connection between the vertical plate 4 and the horizontal plate 7.

[0026] like Figure 1-Figure 2As shown, a lifting assembly is arranged on the outside of the support plate 8, and the lifting assembly consists of a first mounting frame 2, a second mounting frame 3, a first transverse groove 9, a second transverse groove 10, a limiting rod 11, an iron sheet 12, an annular permanent magnet 13, a handle 14, a T-shaped slider 16 and a T-shaped slide groove 17. The sides of the bottom plate 1 are respectively fixedly provided with symmetrical first mounting frames 2 and second mounting frames 3, and the outer side of the second mounting frame 3 is fixedly connected to the vertical plate 4. The front of the first mounting frame 2 is provided with a first transverse groove 9 that runs through to the back, and the front of the second mounting frame 3 is provided with a second transverse groove 10.

The top surface of the first mounting frame 2 is fixedly provided with an annular permanent magnet 13. The limit rod 11 passes through the first transverse groove 9 and the annular permanent magnet 13 respectively. The suction force of the annular permanent magnet 13 on the iron sheet 12 is much greater than the force required for the iron sheet 12 to be vibrated and separated from the first mounting frame 2. A T-shaped slide groove 17 is provided inside the first mounting frame 2. The limit rod 11 is close to the T-shaped slide groove. A T-shaped slider 16 adapted to the T-shaped slide groove 17 is fixedly provided on one side of the groove 17. The T-shaped slider 16 is slidably connected to the first mounting frame 2 through the T-shaped slide groove 17. The T-shaped slider 16 cooperates with the T-shaped slide groove 17 to guide the movement of the limit rod 11. The handle 14 is lifted upward to drive the iron sheet 12 to separate from the annular permanent magnet 13, which can drive the limit rod 11 to move upward, release the limit on the support plate 8, and facilitate the support plate 8 to be pulled out of the first mounting frame 2 and the second mounting frame 3 and moved to the first transverse groove 9 and the second transverse groove 10 of the specified height, thereby adjusting the height of the support plate 8 and improving the device. The applicability of the invention is that after completing the height adjustment, the handle 14 is moved downward to drive the limit rod 11 to move downward back to its original position, the limit rod 11 just clings to the side of the support plate 8, and the annular permanent magnet 13 just contacts the iron sheet 12 and adsorbs the iron sheet 12, thereby fixing the position of the limit rod 11, and reinforcing inclined plates 15 are fixedly provided at the four corners of the bottom surface of the support plate 8, and the reinforcing inclined plates 15 are respectively slidably connected to the first mounting frame 2 and the second mounting frame 3.

[0027] like Figure 1-Figure 4As shown, a support assembly is arranged below the air spring 5, and the support assembly consists of a support base 18, a lifting rod 19, a slot 20, a movable plate 21, a plug rod 22, a return spring 23 and a plug rod 24. A support base 18 is fixedly arranged on the bottom surface of the support column 6, and symmetrical movable plates 21 are arranged on the front and rear sides of the support base 18, and symmetrical plug rods 22, a return spring 23 and a plug rod 24 are fixedly arranged on the inner side of the movable plate 21. A third transverse groove and a fourth transverse groove are arranged inside the support base 18, and the third transverse groove is connected to the fourth transverse groove. One end of the return spring 23 away from the movable plate 21 is fixedly connected to the inner wall of the third transverse groove, and the fourth transverse groove is adapted to the plug rod 22, and the plug rod 22 passes through the third transverse groove, and the plug rod 22 is slidably connected to the support base 18 through the fourth transverse groove. A symmetrical lifting rod 19 is arranged inside the support base 18, and the lifting rod 19 is slidably connected to the support base 18. A support sheet is fixedly arranged on the bottom surface of the lifting rod 19, and a plurality of slots 2 are equidistantly arranged in a linear array on the front and rear sides of the lifting rod 19. The locking plate 21 is moved outwards to drive the locking rod 24 to disengage from the locking plate 20 so as to adjust the position of the lifting rod 19 relative to the supporting base 18. The movement of the movable plate 21 drives the plugging rod 22 to move outwards at the same time, and the return spring 23 is extended, and the plugging rod 22 guides the movement of the movable plate 21. During the movement of the movable plate 21, the plugging rod 22 never disengages from the fourth transverse groove. After the position adjustment of the lifting rod 19 is completed, the locking rod 24 is aligned with the nearest locking slot 20, and then the movable plate 21 is released. The return spring 23 pulls the movable plate 21 to move inwards at the same time, thereby driving the locking rod 24 to move inwards at the same time and engage with the inside of the locking slot 20, so as to limit the lifting rod 19. The supporting assembly can avoid excessive wear when subjected to long-term vibration.

[0028] Specific working principle:

[0029] When the device needs to adjust the height of the support plate 8, the handle 14 is lifted upward to drive the iron sheet 12 to separate from the annular permanent magnet 13, which can drive the limit rod 11 to move upward, release the limit on the support plate 8, and facilitate the support plate 8 to be pulled out of the first mounting frame 2 and the second mounting frame 3 and moved to the first transverse groove 9 and the second transverse groove 10 at the specified height, thereby adjusting the height of the support plate 8 and improving the applicability of the device. After the height adjustment is completed, the handle 14 is moved downward to drive the limit rod 11 to move downward back to its original position, and the limit rod 11 just clings to the side of the support plate 8, and the annular permanent magnet 13 just contacts the iron sheet 12 and absorbs the iron sheet 12, thereby fixing the position of the limit rod 11, and strengthening the inclined plate 15 to support the support plate 8 can strengthen the structural strength of the support plate 8 and the first mounting frame 2 and the second mounting frame 3, thereby improving the stability of the support plate 8.

[0030] The engagement of the clamping rod 24 into the inside of the clamping slot 20 can fix the position of the lifting rod 19 relative to the support base 18, thereby supporting the air spring 5. At the same time, moving the movable plate 21 outward drives the clamping rod 24 to disengage from the clamping slot 20 to adjust the position of the lifting rod 19 relative to the support base 18. The movement of the movable plate 21 drives the insertion rod 22 to move outward at the same time, the return spring 23 is extended, and the insertion rod 22 guides the movement of the movable plate 21. During the movement of the movable plate 21, the insertion rod 22 never disengages from the fourth horizontal groove. After completing the position adjustment of the lifting rod 19, the clamping rod 24 is aligned with the nearest clamping slot 20, and then the movable plate 21 is released. The return spring 23 pulls the movable plate 21 to move inward at the same time, thereby driving the clamping rod 24 to move inward at the same time and engage with the inside of the clamping slot 20, thereby limiting the lifting rod 19. The support assembly can avoid excessive wear when subjected to long-term vibration.
