Problems solved by technology

The damping performance of the existing steel spring isolators is usually adjusted by adjusting or adding the structure of the parts in contact with the damping agent. The adjustment structure is complex, and a wide range of disassembly and adjustment is required to achieve different damping adjustments. The operability is poor and the efficiency is low.
At the same time, the existing vibration isolator cannot realize the function of adjustable damping and replacement without disassembly and effective sealing, and its adjustable damping and poor anti-corrosion and waterproof performance

Embodiment Construction

[0023] 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.

[0024] 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 assembly 4 from the external air and water, and the vibration isolation assembly 4 has excellent anti-corrosion and anti-aging properties, so that each component can be reused and the maintenance cost is low; at the same time, the vibration isolator The excellent waterproof sealing ...

Abstract

The invention provides a vibration isolator for a track floating slab, which comprises an upper cover plate, a bottom plate, a telescopic sleeve and a vibration isolation assembly, and is characterized in that the telescopic sleeve is connected between the upper cover plate and the bottom plate to form a sealed chamber; the vibration isolation assembly comprises a damping agent placed in the sealed chamber, the upper cover plate is provided with a damping adjustment assembly convenient for injecting and extracting the damping agent, the damping adjustment assembly comprises an injection through hole and a sealing plug, the injection through hole is formed in the upper cover plate, and the sealing plug is detachably mounted in the injection through hole. The vibration isolator has the advantages that large-range effective adjustment of damping is guaranteed, damping adjustment is convenient, and efficiency is high.

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 damping performance of the existing steel spring isolators is usually adjusted by adjusting or adding the structure of the parts in contact with the damping agent. The adjustment structure is complex, and a wide range of disassembly and adjustment is required to achieve different damping adjustments. The operability is poor and the efficiency is low. . At the ...
