Problems solved by technology

The belt drive slips during work, so the precise transmission ratio cannot be maintained, the transmission accuracy is low, and the speed of the grinding wheel is unstable, which affects the grinding quality
And the transmission efficiency is low
The belt drive system also results in larger equipment dimensions
[0011] 3. The walking device of the grinding machine is manually pushed through the walking wheel

Abstract

The invention discloses an automatic steel rail lip polishing method, and belongs to the field of rail maintenance. The automatic steel rail lip polishing method is characterized by comprising the following steps that a, an automatic steel rail lip polishing machine is placed on a steel rail; b, the automatic steel rail lip polishing machine is driven by a traveling device of the automatic steel rail lip polishing machine to move in the longitudinal direction of the steel rail, a steel rail lip is polished longitudinally through a grinding wheel, and a horizontal feeding device drives the grinding wheel to transversely polish the steel rail lip at the same time; and c, the grinding wheel is driven by an up-down moving device to move up and down so as to polish any position of the steel rail lip in the height direction. According to the automatic steel rail lip polishing method, the steel rail lip can be polished transversely and longitudinally at the same time, manual adjustment is not needed, different feeding quantities are selected according to steel rail lips with different thicknesses, one-time polishing is achieved, and the polishing speed is constant; the grinding wheel can move up and down, and thus any position of the steel rail lip in the height direction can be polished; and the automatic steel rail lip polishing method has the characteristics of being high in polishing efficiency and good in polishing effect.

Description

technical field [0001] The invention relates to the field of railway maintenance, in particular to an automatic grinding method for rail fat edges. Background technique [0002] At present, the rail grinding and repairing machines used in various works mainly include the French Gisma internal combustion rail grinding machine model MP12, the German Nobel internal combustion rail profiling grinding machine ROBEL13.44, the NC straight 5 type produced in Zhengzhou Luyuan, and the GM produced in Shandong. -4 type, internal combustion turnout grinding machine NCM-4.0 type produced in Jinzhou, NCM-4.9 type produced by Kunming Aotong, etc. [0003] The above rail grinding machines are mainly divided into two categories, rail surface grinding machines and turnout grinding machines. [0004] Rail surface grinding machine, take the GM-4 type produced in Shandong as an example. The GM-4 type grinding machine is mainly composed of main components such as frame, transmission system, grin...
