Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0022] Such as figure 1 As shown, the vibration isolator for the track floating plate in this embodiment includes an upper cover plate 1 , a bottom plate 2 , a telescopic sleeve 3 and a vibration isolation assembly 4 . Wherein, the telescopic sleeve 3 is connected between the upper cover plate 1 and the bottom plate 2 to form a sealed chamber 5, and its structure is simple and compact. At the same time, the setting of the sealed chamber 5 effectively isolates the vibration isolation component 4 from the external air and water, has good anti-corrosion and anti-aging functions, makes each component reusable, and has low maintenance costs; and the vibration isolator has excellent waterproof sealing As a result, the damping agent 41 is prevented from leaking when t...

Abstract

The invention provides a vibration isolator for a track floating slab. The vibration isolator comprises an upper cover plate, a base plate, a telescopic sleeve and a vibration isolation assembly, wherein the telescopic sleeve is connected between the upper cover plate and the base plate to form a sealed chamber; the vibration isolation assembly comprises a damping agent, a spiral damping disc anda spring, and the damping agent is arranged in the sealed chamber. One end of the spiral damping disc is detachably mounted on the upper cover plate, the other end of the spiral damping disc extends into the damping agent, and the spring is installed between the upper cover plate and the base plate. The vibration isolator has the advantages of being adjustable and replaceable damping, low in maintenance cost and the like.

Description

technical field [0001] The invention relates to the field of rail vibration reduction engineering, in particular to a vibration isolator for a rail floating plate. Background technique [0002] The principle of steel spring vibration isolators currently used in urban rail transit is to achieve the purpose of support and vibration reduction through the parallel use of springs and dampers. The damping design of existing steel spring isolators is basically based on the interaction between the spring and the damping agent, and the deformation and displacement of the spring drive the damping agent to generate damping. The adjustable range of the damping performance of the existing steel spring vibration isolator is small, and there is a risk of damping agent leakage and external water entering the interior of the vibration isolator, which affects the damping performance and anti-corrosion and waterproof performance. Contents of the invention [0003] The technical problem to b...
