Vibration isolation device and application thereof

Abstract

The invention relates to a vibration isolation device for reducing the vibration of building units and equipment foundations in the running process of railbound vehicles, which comprises a bearing stop dog and a spring vibration isolator. The bearing stop dog and the spring vibration isolator are arranged in reserve through holes of vibration isolating members; the spring vibration isolator is arranged below the bearing stop dog; the bearing stop dog is provided with at least two hanger rods capable of rotating, translating or swinging; and a transverse extending-outward hanging-connecting stop dog is arranged at the lower part of the hanger rod. The vibration isolation device has compact and reasonable structure and convenient maintenance, solves the problem in the prior art that the bearing stop dog is difficult to restore once being damaged, has good vibration isolation effect, saves materials and reduces the cost on the premise of not influencing the vibration reducing effect, has wider range of application, is easy to process and manufacture and considers economic effect and environmental protection effect; a jacking mounting method of the vibration isolation device has convenient operation and reliable effect; and the vibration isolation device provides more application choices for vibration noise environment control of the construction of equipment, the railbound vehicles and building factories, is particularly suitable for the vibration isolation of a rail floating road bed and building floor or equipment foundation, and has broad popularization and application prospect.

Description

Technical field [0001] The invention belongs to the field of vibration and noise control, and in particular relates to a vibration isolation device for reducing the adverse effects of vibration and noise emitted during the operation of rail vehicles or reducing the vibration of building components and equipment foundations. Background technique [0002] Vibration and noise are recognized as the most widespread public hazards. They not only affect and destroy transportation, buildings and equipment, but also directly cause harm to the human body. Therefore, vibration reduction and noise reduction have become a topic of great concern in the field of environmental protection in recent years. Among the existing vibration and noise reduction technologies, the most successful application and practice in the fields of rail transit and equipment vibration isolation is the component floating technology. The typical track bed floating technology and equipment basic floating technology, etc...

Problems solved by technology

The Chinese patent No. ZL2004100354411 discloses a built-in vibration isolation device. The coupling sleeve of the vibration isolation device is arranged in the floating plate, and the supporting block fixedly arranged on the coupling sleeve is supported as a direct force-bearing element during operation. On the spring vibration isolator, after long-term use, the relevant parts are prone to fatigue damage, open welding, and corrosion. However, since the connecting sleeve has been integrated with the floating plate, it cannot be directly replaced and repaired on site It is very difficult to be limited by the location and the internal space of the connecting sleeve

At the same time, in order to repair and replace the spring isolator at any time, the traditional built-in vibration isolator adopts the technical scheme that the spring isolator can be directly taken out through the through hole on the connecting sleeve, which requires that the size of the through hole must be slightly larger than the spring The size of the vibration isolator, so the size of the connecting sleeve is correspondingly larger, which not only takes up more space but also is not conducive to reducing costs and transportation
