A rubber vibration isolator structure applied to railway track to buffer train vibration

Abstract

The invention relates to the technical field of track buffer vibration isolators, and discloses a rubber vibration isolator structure applied to railway tracks to buffer train vibration, comprising a track, a pad block is arranged at the bottom end of the track, and two sides of the track are provided with a spacer block. Each is provided with a splint, the interior of the splint is provided with a rubber shell, the inside of the rubber shell is fixedly installed with a metal cover, the inside of the metal cover is fixed with rubber particles, and the inside of the rubber particles is fixedly connected with damping. The rubber vibration isolator structure applied to the railway track to buffer train vibration is provided with rubber shells on both sides of the track, the inside of the rubber shell is provided with a metal cover, the inside of the metal cover is provided with rubber granules, and the rubber granules are provided with pressure plates and the second spring, which is convenient for shock absorption and buffering through the rubber shell, metal cover and rubber particles, and the rubber shell, metal cover and rubber particles are all independent units, which is convenient for independent replacement and avoids the phenomenon of high maintenance cost and difficult maintenance. appearance.

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 vibration. Background technique [0002] In recent years, with the vigorous advancement of urban rail transit construction in my country, rail transit brings convenience to people's travel, but also produces vibration and noise problems. On the one hand, it will even affect the stability and safety of trains and shorten the service life of the track in severe cases. 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 effects of environment, fatigue load, geological conditions, etc., during the operation of urban rail transit, the performance of elastic vibration isolation elements will often decline or even fail. In order to maintain 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.
