Polymer composite floating slab track bed vibration isolator easy to replace

Abstract

The invention provides a polymer composite floating slab track bed vibration isolator easy to replace. The polymer composite floating slab track bed vibration isolator comprises a connecting device, apressure bearing device and a vibration isolation device, and the connecting device comprises a foot sleeve, a ball head bolt, a hoisting bolt and a bottom plate connecting bolt, wherein the foot sleeve is pre-buried inside a floating slab and is in fit connection with the ball head bolt through threads, and the end of the ball head bolt is in a hemispheric shape; the pressure bearing device comprises an upper cover plate, a pressure bearing plate and a bottom plate, wherein the pressure bearing plate and the bottom plate are connected with the vibration isolation device, a rubber coating isarranged inside the upper cover plate, the upper surface of the upper cover plate is connected with the floating slab, power is transferred to the pressure bearing plate through the ball head bolt, aspherical groove is formed in the middle of the pressure bearing plate and matched with the spherical surface of the ball head bolt, the vibration isolation device comprises a holder and an elastic base body, the middle of the holder is provided with a hole, and the elastic base body extends into the hole of the holder. According to the easy-to-replace polymer composite floating slab track bed vibration isolator disclosed by the invention, a floating slab track bed vibration isolation system can be conveniently replaced, the vibration isolation effect is good, reliability is high, and the goodvibration isolation effect can be achieved.

Description

technical field [0001] The invention relates to a vibration isolator technology, in particular to a novel vibration isolator for a floating slab track bed. Background technique [0002] Vibration isolation technology isolates the vibration source from the protected object through an auxiliary system that includes a special device, thereby reducing the dynamic coupling between the vibration source and the vibration-isolated object, reducing the transmission of bad vibrations to the protected object or from the object outgoing. [0003] Vibration isolation technology was widely used in aviation, marine, machinery, civil engineering, energy and other industries before. Since it was introduced into the rail transportation industry, people have changed the design ideas of the track and got rid of the traditional method of relying solely on sleepers and gravel. In the vibration reduction mode, the ballastless floating slab ballast bed vibration isolation technology has achieved s...

Problems solved by technology

However, in the current prior art, such as the CN2018100725930 patent, because of the rigid connection between the vibration isolator and the floating slab track, when the vibration isolator of the floating slab track bed needs to be replaced due to damage or other reasons, it is difficult, so A new structure needs to be designed to realize the convenient replacement of the vibration isolation system of the floating slab ballast bed
