Novel structure vibration isolator outer sleeve for floating slab ballast bed

Abstract

The invention relates to a novel structure vibration isolator outer sleeve for a floating slab ballast bed; the outer sleeve comprises a bottom plate, an outer pipe, a lifting lug, a connecting plate and a limiting pin; the outer pipe is welded to the bottom plate, the lifting lug is welded to the outer side wall of the outer pipe, the connecting plate is welded to the inner side wall of the outer pipe, and the connecting plate is of a split type I-shaped structure. And the limiting pin is welded on the inner side wall of the outer pipe. The novel structure vibration isolator outer sleeve for the floating slab ballast bed has the following advantages and effects that 1, a reserved jacking space is formed in the connecting plate, a traditional external jacking tool clamp does not need to be adopted, and the early-stage construction progress of urban rail transit is accelerated; 2, the connecting plate is simple in structure, a complicated maintenance tool is cancelled, and a simple and rapid construction method is designed in a larger space; 3, the novel structure adopts a concise design and manufacturing process, so that the weight of the product is reduced; 4, the welding strength is high; 5, the device is suitable for floating slabs with different heights; and 6, the material utilization rate is high, and economy and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to an outer sleeve of a vibration isolator with a new structure for a floating slab track bed. Background technique [0002] With social development and scientific and technological progress, major cities pay more and more attention to the development of urban rail transit. The construction of urban rail transit, especially the construction of underground railways, has also been greatly expanded. In order to reduce the interference to the upper part of the rail transit or the surrounding properties and residents, it is an important vibration isolation measure in the subway design to install steel spring floating slab track beds in special sections. [0003] Steel spring vibration isolators are widely used, and the integral structure currently adopted by the original structure products has a large size and complex structure, which brings different degrees of inconvenience to the s...

Problems solved by technology

[0003] Steel spring vibration isolators are widely used, and the integral structure currently adopted by the original structure products is large in size and complex in structure, which brings different degrees to the construction site. Inconvenience; the connecting plate parts of the integral structure are heavy, the production is difficult and the efficiency is low
