Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the process of realizing the application, the inventor finds that along with the rapid development of the railway, the operating mileage of the railway in China exceeds 14 kilometers, and the operating mileage of the high-speed railway reaches 3.6 kilometers. The steel rail grinding wagon which is produced by the follow-up operation is used for grinding the steel rail. Because the control of the grinding power of the existing steel rail grinding wagon is realized by controlling the pressure of a pressing oil cylinder or an air cylinder, the pressure control can cause the response speed to be slow, and therefore, the stability is poor. In addition, in the conventional rail grinding method, the relative distance between the grinding stone and the rail is long, and the loss distance of the grinding stone can be changed, so that the falling point of the grinding stone is not accurate.
