Anti-seismic vibration isolation method and anti-seismic vibration isolation device for electromechanical equipment

Abstract

The invention discloses an anti-seismic and vibration-isolation method for electromechanical equipment. The method includes the steps that an anti-seismic and vibration-isolation device is designed, wherein the anti-seismic and vibration-isolation device is designed according to the weight of the electromechanical equipment, the inherent frequency of the electromechanical equipment and seismic defense requirements of the area where the electromechanical equipment is located; the anti-seismic and vibration-isolation device is installed, wherein the anti-seismic and vibration-isolation device is installed on a building body; the electromechanical equipment is installed, wherein the electromechanical equipment is installed on the anti-seismic and vibration-isolation device. The invention further provides the anti-seismic and vibration-isolation device. The specially designed anti-seismic and vibration-isolation device is installed between the electromechanical equipment and the building body by means of the provided anti-seismic and vibration-isolation method for the electromechanical equipment; on the one hand, vibration generated due to work of the electromechanical equipment is effectively isolated; on the other hand, when earthquakes happen, elastic parts can withstand part of action force of the earthquakes, the remaining part of the action force is used for rigid earthquake prevention by a rigid shell, influences of the earthquakes can be effectively resisted, the electromechanical equipment is protected against damage when the earthquakes happen, and accordingly the anti-seismic and vibration-isolation effects are achieved.

Description

technical field [0001] The invention relates to an anti-seismic and vibration-isolation method for electromechanical equipment and an anti-seismic and vibration-isolation device. Background technique [0002] At present, the vast majority of building electromechanical equipment does not have anti-seismic and vibration isolation measures. Most electromechanical equipment is directly anchored to the structure with anchor bolts, which only play a fixed role without professional anti-seismic design. When an earthquake occurs, these bolted equipment cannot resist the strong earthquake force due to the loosening of the bolts due to the natural vibration of the machine during long-term use because the bolts have not undergone a professional anti-seismic design. If the bolt is damaged, the electromechanical equipment will be overturned and damaged, which will lead to functional paralysis of the equipment, and even cause serious secondary disasters. Not only that, due to the rigid b...

Problems solved by technology

When an earthquake occurs, these bolted equipment cannot resist the strong earthquake force due to the loosening of the bolts due to the natural vibration of the machine during long-term use because the bolts have not undergone a professional anti-seismic design. The bolt is damaged, causing the electromechanical equipment to fall over and be damaged, which leads to functional paralysis of the equipment and even serious secondary disasters

Not only that, due to the rigid bolt connection and anchoring method, most electromechanical machines will generate a lot of vibration during operation, and these vibrations are completely transmitted to the structure through the rigid anchor bolts, causing serious vibration interference and noise pollution. Long-term work will cause vibration damage to the structure
