Problems solved by technology

Although the setting of the spring floating plate reduces the impact of the rail vibration on the surrounding environment, it cannot effectively eliminate the harm caused by the rail vibration to the surrounding environment, because the spring floating plate only performs a certain vibration along the direction of the rail vibration. Cushioning, the repetitive small vibration still exists after setting the spring floating plate
In addition, most of the rubber cushions between rails and sleepers are standard cuboid shapes, which are easy to fall off along the direction of train movement under the high-frequency vibration of rails, causing direct damage to rails to sleepers and reducing the safety of railway transportation

Description

technical field [0001] The invention belongs to the field of transportation, in particular to a device for reducing the vibration hazard of rails during railway transportation. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, the requirements for the speed, comfort and safety of railway locomotives are also continuously improved when traveling. As the running speed of the train continues to increase, the vibration generated during the running of the train also increases, and the adverse effects on the surrounding environment are also increasing. Require. [0003] In order to reduce the impact of the vibration generated by the rails during the operation of the train on the surrounding environment, the existing technology mainly uses the floating plate technology, that is, a spring floating plate is installed on the foundation, and the sleepers and rails are fixed on the floating plate. Al...
