[0030] As shown in Figure 1 and Figure 2 , a lifting vibration isolation column, which is composed of a support outer cylinder assembly, a servo electric cylinder assembly, a telescopic support cylinder assembly, and an air spring flexible assembly, forms a main structure, but when assembled, it needs to be adjusted in sequence according to the structural characteristics, and it is assembled from the inside out, from the bottom up, and the specific steps are as follows:

[0031] Step 1: After the servo motor mounting flange 7 and the servo motor cylinder body 4 are connected by mounting connecting bolts 23 and mounting connecting nuts 14, the servo motor mounting flange 7 and the servo motor mounting support cylinder 5 are connected by mounting connecting bolts 23 at one end of the servo motor mounting support cylinder 5, and the other end of the servo motor mounting support cylinder 5 is connected to the first flange plate 6 by mounting connecting bolts 23. Finally, the top of the servo motor screw rod is screwed into the threaded hole at the top of the servo motor screw rod 3.

[0032] Step 2: The third support outer cylinder 1 is connected to the fifth flange plate 12 by fastening screws at the bottom end (with a notched end), and the top end is connected to the first flange plate 6 assembled in step 1 by mounting connecting bolts 23.

[0033] Step 3: The second support outer cylinder 13 is connected to the third flange plate 14 at one end by fastening screws, and the other end is connected to the second flange plate 9 by fastening screws. The second flange plate 9 is connected to the first flange plate 6 in step 2 by mounting connecting bolts 23 and mounting connecting nuts 14.

[0034] Step 4: Two places of wear-reducing material 10 are pasted in the corresponding positioning grooves of the first support outer cylinder 8 by high-molecular adhesive. After it is completely solidified, the bottom end of the first support outer cylinder 8 is connected to the fourth flange plate 15 by fastening screws. Then the assembled fourth flange plate 15 is connected to the third flange plate 14 in step 3 by mounting connecting bolts 23 and mounting connecting nuts 14.

[0035] Step 5: Special adhesive for magnetic ruler 21 is pasted into the corresponding groove of telescopic cylinder 36. After it is completely solidified, the telescopic cylinder 36 is inserted into the assembled body in step 4. Rotate and adjust the telescopic cylinder 36 so that the positioning groove corresponds to the positioning hole on the first support outer cylinder 8. Screw in the appropriate length of the guide screw 18 and lock the guide screw lock nut 17. Then install the reading head mounting seat 20 and the reading head 19 into the corresponding magnetic ruler detection port 21 of the first support outer cylinder 8 by fastening screws, and adjust to the appropriate distance.

[0036] Step 6: Air spring 22 is installed on the top of telescopic cylinder 36 by bolts. Height valve mounting plate 25 and height valve 26 are installed on the corresponding position of air spring 22 by bolts. Connection mounting plate 30 is installed on the top of air spring 22 by bolts. Limiting column 27 is screwed into the mounting threaded hole at the top of telescopic cylinder 36 by outer thread at the root. Limiting baffle 29 is inserted into the outer thread at the upper part of limiting column 27, and two limiting column lock nuts 28 are screwed into the appropriate position for limiting.

[0037] The assembly of the lifting vibration isolation column is completed through the above steps 1-6.

[0038] The lifting vibration isolation column of the application needs more than three non-linear arrangements, each of which has a servo electric cylinder screw position sensor and a telescopic support cylinder assembly position sensor for real-time detection and feedback, and is controlled by a computer system, and the servo electric cylinder is internally provided with a brake system including a speed reducer, a servo motor and a brake.

[0039] The lifting vibration isolation column of the application is used in the following manner during working time:

[0040] According to the connection support positions of the platform or frame, a plurality of installation positions on the ground and four corner mounting hole positions of the mounting seat 16 are determined, and the pre-buried foundation bolts 31 are buried and installed and leveled at each position. The assembled lifting vibration isolation column is installed and fastened on the fixed mounting seat 16 by bolts. Then each connection support position of the platform or frame is fastened and connected with the connection mounting plate 30 of the lifting vibration isolation column by bolts (note that the lifting vibration isolation column is in the 0 position state without being raised during the installation process); finally, the circuit and air circuit of each lifting vibration isolation column are connected and debugged.

[0041] When the platform or frame is raised after installation, the user only needs to click the raise button on the computer screen, and the computer system will automatically control the raising of each lifting vibration isolation column. First, the brake system of each servo electric cylinder is released, and then the servo electric cylinder screw 3 is raised synchronously, and the servo electric cylinder screw top head 2 at the top of the telescopic support cylinder assembly is raised. During the raising process, each lifting vibration isolation column is detected by the servo electric cylinder screw position sensor and the telescopic support cylinder assembly position sensor in real time, and the feedback is given to the computer system. When the height difference of each lifting vibration isolation column appears, the computer system automatically adjusts the lifting vibration isolation column for fine tuning to ensure consistent height. When the required height is reached, the user only needs to click the stop button on the computer screen, and the servo electric cylinder screw 3 of each lifting vibration isolation column stops rising synchronously, and the brake system of the servo electric cylinder is tightly held. If the user does not click the stop button on the computer screen, the servo electric cylinder screw 3 of each lifting vibration isolation column will automatically stop after rising to the maximum stroke of the servo electric cylinder screw 3, and the brake system of the servo electric cylinder will be tightly held. After the lifting vibration isolation column is raised, the user clicks the inflation button on the computer screen, and each air spring flexible assembly starts to inflate. When the height valve 26 reaches the set height, the inflation stops, and the platform or frame is in a state of flexible support and vibration isolation.

[0042] When the platform or frame descends, the user clicks the exhaust button on the computer screen, and each air spring flexible component begins to exhaust air. Once all the internal gas is exhausted and there is no more exhaust sound, the user clicks the descent button on the computer screen. The computer system then automatically and uniformly controls the descent of each lifting vibration isolation column. First, the brakes of each servo electric cylinder brake system are released. Then, each servo electric cylinder lead screw 3 descends synchronously, and its telescopic support cylinder assembly descends together with the top servo electric cylinder lead screw head 2 under the action of gravity. During the descent, each lifting vibration isolation column is subjected to the position sensors of the servo electric cylinder lead screw and the telescopic support cylinder assembly. The sensor detects in real time and feeds back to the computer system. When there is a difference in the descent height of each lifting vibration isolation column, the computer system automatically adjusts the lifting vibration isolation columns to ensure consistent descent height. Once the required height is reached, the user only needs to click the stop button on the computer screen, and the servo electric cylinder screw 3 of each lifting vibration isolation column will stop descending synchronously, and the servo electric cylinder brake system will engage. If the user does not click the stop button on the computer screen, the servo electric cylinder screw 3 of each lifting vibration isolation column will descend synchronously to the 0 position of the servo electric cylinder screw 3 and then automatically stop, and the servo electric cylinder brake system will engage.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
