Abstract

The invention discloses a floating ballast bed, which includes a floating slab, a gasket and a vibration isolator. An installation through hole for jacking is formed in the floating slab, an upper limiting plate and a lower limiting plate are arranged in the installation through hole, and the vibration isolator is arranged in the installation through hole; and the gasket can be placed between thelower limiting plate in the installation through hole and the vibration isolator through the upper limiting plate and form staggered overlapping with the lower limiting plate, and a jacking through hole is formed in the middle of the gasket. The invention further discloses a jacking device suitable for the floating ballast bed. The jacking device includes a clamping part, a jacking part and a driving part, the clamping part is used for supporting the upper limiting plate of the floating slab, the jacking part can penetrate through the jacking through hole of the gasket and abuts against the vibration isolator, and the driving part is used for driving the jacking part and the clamping part to move oppositely. The floating ballast bed adopts a single hole position structure, the manufacturing cost is lowered while fast and convenient installation and maintenance are ensured.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a floating ballast bed and a jacking device thereof. Background technique [0002] With the rapid development of my country's economy, people's quality of life is gradually improving. Energy conservation, emission reduction, and noise reduction have become the growing needs of people in major cities for a better life. The development of urban rail transit can not only effectively improve the urban traffic environment, but also contribute to urban construction and economic development. However, rail transit brings convenience and vibration and noise problems that cannot be ignored. [0003] At present, a better solution is to install the track on a floating ballast bed. The floating ballast bed is supported on the ballast bed foundation through a vibration isolator. The floating ballast bed can provide enough inertial mass to balance the dynamic load generated by the vehicle....
