Combined rubber vibration isolator for floating slab track

Abstract

The invention discloses a combined rubber vibration isolator for a floating slab track. The vibration isolator is composed of an upper metal piece, a rubber elastic piece, a lower metal piece and a locking component. The rubber elastic piece has the conical outer circumferential face and the conical inner circumferential face, and the outer circumferential face and the inner circumferential face of the rubber elastic piece are tightly attached to the upper metal piece and the lower metal piece respectively; the rubber elastic piece comprises a rubber piece body, an outer ring skeleton, a middle ring skeleton and an inner ring skeleton; the outer ring skeleton, the middle ring skeleton and the inner ring skeleton are arranged inside the rubber piece body separately and vulcanized with the rubber piece body into a whole. The locking component sequentially penetrates through the lower metal piece, the rubber elastic piece and the upper metal piece from bottom to top, the upper portion ofthe locking component is in spiral connection with the upper metal piece, and the lower portion of the locking component abuts against the lower metal piece. The invention further discloses an installing method of the combined rubber vibration isolator for the floating slab track. The vibration isolator is simple in structure, easy to disassemble, assemble, replace and maintain, and low in maintain cost.

Description

technical field [0001] The invention relates to a vibration reduction and noise reduction technology, in particular to a rubber vibration isolator used for a floating plate track. Background technique [0002] Urban rail transit has gradually become the main means of transportation for the public, which inevitably brings about vibration and noise pollution while bringing fast transportation. At present, among the vibration and noise reduction methods in the urban rail transit industry, the vibration isolation effect of the floating slab track is the most ideal, and it has been widely used in practical engineering. The vibration reduction mechanism of the floating slab track is mainly to use elastic vibration isolators to completely isolate the upper structure of the track from the foundation, so that it is in a suspended state, thereby effectively isolating the transmission of the impact vibration of the wheel and rail to the surrounding foundation. [0003] The vibration i...

AI Technical Summary

Problems solved by technology

The upper cover plate, upper iron part, rubber part, lower iron part, and lower seat plate are sequentially connected, wherein the upper iron part and the lower iron part are vulcanized into one with the rubber part, therefore, it is necessary to target the upper iron part during replacement and maintenance. , Rubber parts and lower iron parts are replaced and maintained as a whole, which increases the maintenance cost in the later period
