Rubber vibration isolator structure applied to railway track for buffering train vibration

Abstract

The invention relates to the technical field of track buffering vibration isolators, and discloses a rubber vibration isolator structure applied to a railway track for buffering train vibration. The rubber vibration isolator comprises a track, a cushion block is arranged at the bottom end of the track, clamping plates are arranged on both sides of the track, rubber shells are arranged in the interiors of the clamping plates, metal covers are fixedly installed in the interiors of the rubber shells, rubber particles are fixedly installed in the interiors of the metal covers, and dampers are fixedly connected to the interiors of the rubber particles. According to the rubber vibration isolator structure applied to the railway track for buffering the train vibration, the rubber shells are arranged on the two sides of the track, the metal covers are arranged in the interiors of the rubber shells, the rubber particles are arranged in the interiors of the metal covers, and pressing plates and second springs are arranged in the rubber particles, so that damping and buffering are conveniently carried out through the rubber shells, the metal covers and the rubber particles; and the rubber shells, the metal covers and the rubber particles are all independent units, so that independent replacement is conveniently carried out, and the phenomena of over-high maintenance cost, difficult maintenance and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of track buffer vibration isolators, in particular to a rubber vibration isolator structure applied to railway tracks to buffer train vibrations. Background technique [0002] In recent years, with the vigorous promotion of my country's urban rail transit construction, rail transit has brought convenience to people's travel, but also has vibration and noise problems. On the one hand, it not only brings troubles to the lives of nearby residents and endangers the safety of surrounding buildings. On the one hand, it will even affect the stability and safety of the train and shorten the service life of the track. Therefore, in order to reduce the vibration and noise hazards caused by rail transit during operation, a series of effective vibration reduction measures have been widely used. [0003] Due to the influence of the environment, fatigue load, geological conditions, etc. during the operation of urban rail t...

Problems solved by technology

[0004] At present, the elastic vibration isolators under the floating plate track in China are mainly divided into two types: steel spring vibration isolator and rubber vibration isolator. Although the steel spring vibration isolator has a relatively long service life, there are metal materials that are easy to corrode and damping materials. Easy to leak, difficult to adjust vertical stiffness, and obvious standing wave effect at high frequencies, etc., and expensive; rubber isolators have the characteristics of damping and energy consumption while the rubber material deforms itself, so the structure is simple, easy to use and inexpensive Relatively cheap, but the rubber vibration isolator in the rubber floating plate track generally produces compression deformation, low lateral stiffness and poor vibration isolation effect, and the rubber material is easily damaged when it bears a large working load and unexpected strong impact load for a long time. The service life is low, and there are also problems such as inconvenient replacement of rubber materials, high maintenance costs, and complicated positioning and installation in construction.
