AI Technical Summary
Technical Problem
The existing floating plate vibration isolators cannot achieve precise adjustment because the varying thickness of the steel plates causes different load forces during adjustment.
Method used
An adaptive gasket structure using a hydraulic cylinder and a high-pressure airbag is adopted. By adjusting the position of the piston end through oil injection or release, the distance between the vibration isolator and the gasket can be precisely adjusted. Combined with a limiting structure and a pressure gauge, the load force can be evenly distributed.
Benefits of technology
It enables precise adjustment of the floating slab, avoids load force differences caused by tiered slab thickness, and ensures uniform slab elevation and stress distribution.

Abstract
This utility model discloses an adaptive shim for a floating slab vibration isolator, belonging to the field of rail transit engineering technology. It includes a vibration isolator assembly and a limiting structure for restricting the shim height. The vibration isolator assembly has a shim body at its top, and a placement groove is formed at the bottom of the shim body. A hydraulic cylinder for adjusting the shim height is installed in the inner cavity of the placement groove. The piston end of the hydraulic cylinder is in contact with the surface of the vibration isolator assembly. An oil injection nozzle is provided at the top of the hydraulic cylinder, and a through hole is formed at the top of the shim body. The position of the through hole corresponds to the position of the oil injection nozzle. Through the cooperation of the hydraulic cylinder and the piston end, the elevation, force magnitude, and uniform force distribution of the slab can be adjusted. This solution avoids the load force differences caused by the thickness gradient of the slab during adjustment, achieving precise adjustment of the floating slab.
