These devices run at high speeds to generate exciting forces, causing foundation vibrations and generating solid sound. If the vibration isolation measures are not taken properly, there will be obvious vibrations and noise in the rooms adjacent to the equipment, which will have a serious impact on the residents. In order to make the deformation of the shock-absorbing pad the same during installation, the existing vibration equipment often needs to be moved to adjust, or springs or viscous dampers are used to achieve energy dissipation and vibration reduction.

[0041] See the instruction manual Figure 3 , 5 As shown in 6, the levelness detection component 6 includes a second universal ball 601, which is rotatably connected to a universal rotation groove 604 opened in the middle of the shock absorbing platform 2. The upper and lower sides of the universal rotation groove 604 are opened, and a conical notch 605 is opened at the upper opening of the universal rotation groove 604. The lower side of the second universal ball 601 protrudes from the lower opening of the universal rotation groove 604. The upper and lower sides of the second universal ball 601 are respectively fixedly connected with an upper indicator rod 606 and a suspension rod 602.

[0045] Working principle:

[0046] During use, when it is necessary to install the construction equipment for shock absorption, firstly, the ground where the construction equipment needs to be installed is leveled and cleaned, then the base 1 is placed flat on the cleaned plane, the push rod of the first electric telescopic rod 501 of the auxiliary support rod structure 5 is extended to the maximum stroke, and then the push rod of the second electric telescopic rod 505 is extended to drive the first electric telescopic rod 501 to hinge and rotate, so that the slide cylinder 502 and the slide rod 503 move downward, so that the tip of the positioning plug 504 abuts against the ground, and then the push rod of the first electric telescopic rod 501 is retracted, driving the slide cylinder 502 and the slide rod 503 to deflect and tilt toward the base 1 under the support of the positioning plug 504, and then ... The push rod 5 extends to drive the first electric telescopic rod 501 to hinge and rotate. At this time, the axial direction of the second electric telescopic rod 505 is consistent with the axial direction of the slide tube 502. The first pressure sensor 510 can detect the support pressure and transmit the detected electrical signal to the PLC controller 8, which is used to feed back to the PLC controller 8 to control the first electric telescopic rod 501 and the second electric telescopic rod 505, so as to ensure that the pressure detected by the first pressure sensor 510 of each auxiliary support rod structure 5 is kept within a certain pressure value range, thereby achieving the stability of the auxiliary support of the construction equipment and avoiding the auxiliary support rod structure 5 from bending and being damaged due to excessive pressure when tilting to one side;

[0047] When the shock absorbing platform 2 vibrates and tilts, the level detection component 6 can drive the upper indicator rod 606 to deflect by the cooperation of the pendant 603 and the suspension rod 602. The upper indicator rod 606 drives the indicator ball 607 to push the push plate 608 in the tilting direction, thereby driving the corresponding second guide rod 609 to compress the third spring 613 and the second pressure sensor 614. After the second pressure sensor 614 detects that the pressure reaches a certain value, the PLC controller 8 drives the corresponding height adjustment component 4 to adjust the height of the shock absorbing platform 2.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
