Description

Technical Field

[0001] This application relates to the field of vibration damping base technology for electromechanical equipment, and more specifically, to a vibration damping and pressure-resistant device for electromechanical equipment. Background Technology

[0002] Electromechanical equipment often vibrates during operation due to motor operation. Combined with the impact of earthquakes, seismic and pressure-resistant bases are necessary during installation. These bases utilize elastic elements such as springs to absorb and disperse vibration energy, reducing the vibration transmitted to the equipment, thus protecting it, improving its stability, and effectively extending its service life. The existing seismic base with publication number CN114151655B presents a design where the amplitude of equipment sway gradually decreases from top to bottom. Since the damping coefficients of all dampers gradually decrease from top to bottom, the damping coefficients of the upper dampers are larger, resulting in better energy dissipation at that height. However, the inventor believes that the aforementioned technology still has the following drawbacks: the seismic base in the literature only has one seismic damper connected to the equipment, resulting in a single seismic resistance method, limited seismic performance, and impacting the service life of the equipment. Therefore, we propose a vibration damping and pressure-resistant device for electromechanical equipment. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a vibration damping and compression-resistant device for electromechanical equipment, which solves the technical problem in the prior art where only one vibration damper is installed on the seismic base connected to the electromechanical equipment, resulting in a single vibration damping method, limited vibration resistance performance, and impact on the service life of the electromechanical equipment. This application achieves the following: the device is installed on the electromechanical equipment, with a rubber pad at the bottom of the base plate for cushioning and vibration damping; the mounting plate is pressed against the corrugated sleeve on the corresponding concave block by two guide rods and damped by insertion along the damping ring, achieving the damping and compression-resistant purpose of the mounting plate; the mounting plate also moves the square plate via a screw, utilizing four dampers to achieve vibration damping and compression resistance. Compared to traditional seismic bases, by adding guide rods and damping sleeves, and by increasing the number of dampers, the vibration damping and compression-resistant capacity of the seismic base is greatly increased, extending the service life of the electromechanical equipment.

The device secures the electromechanical equipment to the four corners of the mounting plate 9 using bolts and threads, and secures the base plate 1 to the four corners using bolts and threads. The base plate 1 is fitted with a rubber pad 2 between it and the base to achieve a certain buffering and shock absorption purpose. The mounting plate 9 is threadedly connected to the square plate 5 by a screw 6. The mounting plate 9 is installed by two guide rods 8 along the damping sleeve 7 on the corresponding concave block 3. The bottom end of the guide rod 8 is threaded with an anti-loosening nut 82 at the bottom surface of the concave block 3 to prevent the guide rod 8 from falling off the concave block 3. The guide rod 8 compresses the damping sleeve 7 and moves along the damping sleeve 7 to achieve the damping and pressure resistance purpose of the mounting plate 9. At the same time, the mounting plate 9 drives the square plate 5 to move down by the screw 6. The four dampers 4 can be used to achieve the shock absorption and pressure resistance purpose. Compared with the traditional seismic base, the overall device greatly increases the shock absorption and pressure resistance capacity of the seismic base by adding guide rods 8 and damping sleeves 7 and by increasing the number of dampers 4, thus extending the service life of the electromechanical equipment.

[0028] Reference Figure 1 and Figure 3 A first through hole 11 is provided at each of the four corners of the base plate 1, and a second through hole 21 is provided at each of the four corners of the rubber pad 2. The first through hole 11 and the second through hole 21 are set in a one-to-one correspondence. The rubber pad 2 is installed on the bottom surface of the base plate 1, and the base plate 1 and the rubber pad 2 are fixed to the base at the four corners by bolt threads.

[0029] Reference Figure 1 and Figure 3 A rectangular groove is provided on the bottom surface of the base plate 1, and a rectangular block 22 is fixed on the rubber pad 2. The rectangular block 22 is embedded in the rectangular groove. The rubber pad 2 is installed in the rectangular groove on the bottom surface of the base plate 1 by using the rectangular block 22 to prevent the rubber pad 2 from slipping.

[0030] Reference Figure 1 and Figure 3 Each concave block 3 has a mounting hole 31. The damping sleeve 7 includes a corrugated sleeve 71 and a damping ring 72. The corrugated sleeve 71 and the damping ring 72 are integrally fixedly connected. The damping ring 72 is limited and fitted into the mounting hole 31. The corrugated sleeve 71 has elastic plastic deformation properties. Combined with the friction damping effect between the damping ring 72 and the guide rod 8, a damping and pressure resistance effect can be achieved.

[0031] Reference Figure 1 and Figure 2 The bottom end of the guide rod 8 is provided with a threaded section 81. The guide rod 8 is threadedly connected to the anti-loosening nut 82 through the threaded section 81. The guide rod 8 is inserted along the corrugated sleeve 71 and the damping ring 72 and passes through the concave block 3. The bottom end of the guide rod 8 is threadedly connected to the anti-loosening nut 82 through the threaded section 81. Thus, when the mounting plate 9 moves upward, the upward movement of the guide rod 8 can be limited by the anti-loosening nut 82 to prevent the guide rod 8 from falling off the concave block 3.

[0032] Reference Figure 2 and Figure 3 The screw sleeve 91 has a through hole 911, and the screw rod 6 has a screw hole and a locking rod 61 is threadedly installed.

The screw rod 6 is installed along the bottom surface of the square plate 5 and is threadedly connected to the screw sleeve 91 at the center of the square plate 5 and the mounting plate 9 in sequence. Then, at the connection between the screw rod 6 and the screw sleeve 91, the locking rod 61 is threadedly connected to achieve a locking treatment, which can prevent the screw rod 6 from loosening.

[0033] Reference Figure 1 and Figure 2The damper 4 includes a piston cylinder 41 and a piston rod 42, which are slidably connected. A buffer spring 43 is sleeved on the outside of the piston rod 42. The buffer spring 43 is limited and installed between the port of the piston cylinder 41 and the top of the piston rod 42. The damper 4 is composed of a piston cylinder 41, a piston rod 42 and a buffer spring 43. The piston rod 42 slides along the inner cavity of the piston cylinder 41 to dampen and slide, and the buffer spring 43 is used to achieve the purpose of damping and shock reduction.

[0034] Working principle: During installation, the base plate 1, which has rubber pads 2 embedded in it, is fixed to the base with four bolts. The mounting plate 9 is then installed by damping insertion along the damping sleeves 7 of the corresponding concave blocks 3 using two guide rods 8. The bottom end of the guide rod 8 is threaded with an anti-loosening nut 82 at the bottom surface of the concave block 3 to prevent the guide rod 8 from falling off the concave block 3. Then, the square plate 5 and the screw sleeve 91 at the center of the mounting plate 9 are threaded together by the screw 6, and the screw 6 and screw sleeve 91 are limited by the locking rod 61 to increase the connection strength between the mounting plate 9 and the square plate 5 and prevent the screw 6 from loosening. The four corners of the mounting plate 9 are secured with screws. The electromechanical equipment is fixedly connected by bolt threads. When the electromechanical equipment is running, a rubber pad 2 is set between the base plate 1 and the base to achieve a certain buffering and shock absorption purpose. The mounting plate 9 compresses the damping sleeve 7 through two guide rods 8 and moves along the damping sleeve 7 in a damping plug-in manner to achieve the damping and pressure resistance purpose of the mounting plate 9. At the same time, the mounting plate 9 drives the square plate 5 to move down through the screw 6. The four dampers 4 can be used to achieve the purpose of shock absorption and pressure resistance. Compared with the traditional seismic base, the overall device greatly increases the shock absorption and pressure resistance capacity of the seismic base by adding guide rods 8 and damping sleeves 7 and by increasing the number of dampers 4, thereby extending the service life of the electromechanical equipment.
