Design of High-speed Railway Concrete Architrave Overall Grinding Machine
Abstract: This project was a design of integrate grinding machine for high-speed rail road. In this project, the skeleton of the machine was designed in a box-type way. It installed nine grinding chute integrally, which perfectly machined the substructure of the high-speed rail once and for all. Moreover, this project intended to drive the grinding chute by high-speed ac motor directly. With this design, not only the rolling teeth transmission could be cut down, but also errors and instability of the intermediate process could be reduced. This project was aimed at promoting the accuracy and efficiency in the building for substructure of the high-speed rail road. And it would bring profound impacts on the development of high-speed rail road, and even more profound effects on the development of economy.
Key words: box-type girder, substructure of the high-speed rail, grinding machine
