Intelligent grinding apparatus for high-speed rail

Abstract

The invention relates to an intelligent grinding apparatus for a high-speed rail. The intelligent grinding apparatus comprises a self-stabilized moving device capable of stable self-adjustment of a grinding direction according to a bend shape of a rail such that the intelligent grinding apparatus is applicable to grinding rails of different trajectory shapes, and wide in range of application. A grinding baseplate is mounted on a lower end face of the self-stabilized moving device. Four 4# hydraulic cylinders are symmetrically mounted on a lower end of the grinding baseplate. Adjustable grinding devices are mounted on top ends of the four 4# hydraulic cylinders. The four 4# hydraulic cylinders are capable of adjusting a grinding height of the intelligent grinding apparatus for a high-speed rail such that the intelligent grinding apparatus is suitable for grinding rails at different terrain elevations. The adjustable grinding devices are capable of completely and closely fitting with the surfaces of rails for grinding back and forth, allowing for large grinding range, good grinding effect and high working efficiency. The intelligent grinding apparatus for a high-speed rail is capable of realizing full-automatic grinding function for rails without manual operation, and high in automation degree.

Description

technical field [0001] The invention relates to the technical field of rail processing, in particular to an intelligent grinding device for high-speed rail tracks. Background technique [0002] With the continuous development of high-speed rail technology, the quality requirements of rails are getting higher and higher. Since the speed of high-speed rails, bullet trains, and subways is much higher than that of ordinary trains, the smoothness of rails is highly required, and the main factors that affect the smoothness of rails There are the following aspects: 1. After the main body of the rail is produced and formed, there will be many burrs on the surface, and the smoothness of the rail is poor; 2. Secondary welding is required between the 100-meter long rails, but after welding The welding points under the rail are extremely uneven on the track, which affects the smoothness of the rail; 3. The rails in use may be corroded for a long time and may also produce rust spots, whi...
