[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A vibration absorbing device for industrial vertical rotating equipment includes a vibration absorber shell 1, a mounting mechanism is provided below the vibration absorber shell 1, a barrel shell 5 is installed inside the vibration absorber shell 1, a variable mechanism is provided inside the barrel shell 5, a vibration absorbing mechanism is provided between the barrel shell 5 and the vibration absorber shell 1, and a circular cover plate 4 is installed on the top of the vibration absorber shell 1. The mounting mechanism can quickly install the device on the rotating equipment, the variable mechanism can control the vibration frequency of the device, and the vibration absorbing mechanism can absorb the vibration to achieve the purpose of vibration reduction.

[0022] As a technical optimization solution of the utility model, the installation mechanism includes a supporting rib plate 2. Two supporting rib plates 2 are installed at the bottom of the vibration absorber housing 1. The two supporting rib plates 2 are fixedly installed in a bilaterally symmetrical manner, making the installation of the device more stable.

[0023] As a technical optimization solution of the utility model, a first thread groove 3 is vertically opened at one end of the support rib plate 2 away from the vibration absorber housing 1, and the first thread groove 3 is a through-design. The method of fixing by bolts is simple and quick.

[0024] As a technical optimization solution of the utility model, the variable mechanism includes a mass block 7, and a plurality of mass blocks 7 are movably placed inside the barrel shell 5, and the outer side of the mass block 7 abuts against the inner wall of the barrel shell 5. By changing the number of mass blocks 7, the purpose of changing the vibration frequency of the device is achieved, and the convenience of using the device is increased.

[0025] As a technical optimization solution of the utility model, a plurality of second thread grooves 6 are provided at the bottom end of the inner wall of the drum shell 5, and a plurality of openings 8 are provided through the mass block 7, and the aperture and position of the openings 8 correspond to the second thread grooves 6. The mass block 7 is fixed by installing bolts through the openings on the second thread grooves 6, which is simple and quick and increases the convenience of use of the device.

[0026] As a technical optimization solution of the utility model, the vibration absorption mechanism includes a sealed cavity 9 and a spring 10. A plurality of sealed cavities 9 are evenly installed on the outer wall of the drum shell 5 along the circumferential direction. The spring 10 is installed inside the sealed cavity 9. Silicone oil damping 11 is injected into the sealed cavity 9. When the device vibrates, the vibration amplitude is consumed by the relative movement of the spring 10 and the silicone oil damping 11, thereby absorbing the vibration and achieving the purpose of vibration reduction.

[0027] As a technical optimization solution of the utility model, one end of the spring 10 abuts against the inner wall of the shock absorber housing 1, and the other end of the spring 10 abuts against the outer wall of the drum shell 5. The spring 10 is compressed to a preset degree and then placed inside the sealed cavity 9, and positioning blocks are provided at the abutment points between the spring 10 and the inner wall of the shock absorber housing 1 and the outer wall of the drum shell 5. The positioning blocks can be inserted into the ends of the spring 10 to limit the ends of the spring 10, preventing the spring 10 from deflecting during use and affecting the actual use effect. The purpose of vibration reduction is achieved through the shaking of the spring 10 in combination with the silicone oil damping 11.

[0028] When the utility model is in use, a threaded hole corresponding to the first thread groove 3 is opened on the top of the vertical rotating device on which the device is to be installed. Then the staff moves the device to the top of the vertical rotating device and aligns the first thread groove 3 with the threaded hole of the vertical rotating device. Then the staff fixes the device on the top of the vertical rotating device by installing fixing bolts. The circular cover plate 4 plays a role of dust prevention and protection for the interior of the shock absorber housing 1 during the use of the device.

[0029] The installation method of the mass block 7 is that the staff manually places the mass block 7 into the interior of the barrel shell 5, ensuring that the second thread groove 6 corresponds to the opening 8 during placement. After placing a preset number of mass blocks 7, the staff passes a preset bolt through the opening 8 and screws it to the second thread groove 6 to complete the fixation of the mass block 7.

[0030] The staff tested the vibration frequency of the vertical rotating equipment when it was working, and then installed a corresponding number of mass blocks 7 inside the barrel shell 5 according to the vibration frequency actually measured, thereby ensuring that the device can resonate at the same frequency as the vertical rotating equipment. When the device is in use, the staff can change the natural frequency of the device by increasing or decreasing the number of mass blocks 7 in the barrel shell 5, so that the natural frequency of the device is the same as the natural frequency of the vertical rotating equipment, thereby ensuring that the device resonates at the same frequency with the connected vertical rotating equipment, and maximizing the vibration of the vibration-absorbing components inside the device. In this way, when the device is dealing with equipment with different vibration frequencies, the number of mass blocks 7 can be changed so that the device can maintain the same frequency vibration as the rotating equipment, which is convenient and quick and greatly increases the ease of use and practicality of the device.

[0031] When the vertical rotating equipment vibrates, the vibration is transmitted to the vibration absorber housing 1 through the supporting ribs 2, and then the device generates vibrations of the same frequency. At this time, the spring 10 and the silicone oil damping 11 play a role in vibration reduction. When the device vibrates, the vibration amplitude is consumed by the relative movement of the spring 10 and the silicone oil damping 11, thereby absorbing the vibration and achieving the purpose of vibration reduction.

[0032] Since the vibration energy of the vertical rotating equipment is generally constant, after the vibration energy is transmitted to the device, the vibration energy is consumed by the spring 10 and the silicone oil damping 11 inside the device, thereby reducing the vibration of the equipment. After the device resonates with the vertical rotating equipment at the same frequency, the vibration energy is the largest and the energy absorbed is the most, further optimizing the vibration reduction effect of the vibration absorbing device.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
