Background

The turnouts in rail transportation of countries in the world cannot be opened, and the turnouts used in rail transportation of countries (including China) are designed for one hundred years and are used as old turnouts nowadays. When the train passes through the existing railway turnout, the whole train can generate huge shaking, vibration and noise when passing through the turnout due to the turnout design structure, the existing railway turnout (as shown in figure 1) is fixedly provided with guide rails at the inner ends of the outer rails at two sides respectively, and when the train passes through, an outer wheel can forcibly guide the train to walk on the track No. 1 or the track No. 2.

When each wheel of the train passes through the guide rail, the side friction force, namely resistance, of more than ten tons is generated between each train and the guide rail, each train is about 40-50 sections of carriages, a passenger train is about 10 sections of carriages, and when more than 400 wheels of each train pass through turnouts, the abrasion of the guide rail, the wheels, a carriage damping system and the like of related equipment is caused, the loss of parts is great, the energy consumption is very great, and the service life of related parts is shortened. Therefore, the railway workers need to increase the daily maintenance time, the effective time of railway transportation is reduced, and the cost performance of the railway transportation is obviously influenced.
