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
[0012] 3. The walking device of the grinding machine is manually pushed through the walking wheel

Abstract

The invention discloses a steel rail fat edge automatic grinding machine, and belongs to the field of railway maintenance equipment. The automatic grinding machine comprises a machine frame, and is characterized by further comprising an up-down moving device, a traveling device and a horizontal feeding device; the up-down moving device comprises a hanging bracket, ball bearing seats, ball screws and ball nuts; a stepping motor and upper and lower sliding blocks are arranged on the machine frame; the traveling device comprises a driving gear, a driven gear, a traveling wheel, a roller and a motor; the horizontal feeding device comprises a grinding wheel, a gear acceleration box, a movable platform, a horizontal sliding block, a driving mechanism, a pulse motor and a ball screw pair; an output shaft of the gear acceleration box is connected with the grinding wheel, and an input shaft is connected with the driving mechanism. The grinding machine can be used for simultaneously grinding a steel rail fat edge in the transverse direction and in the longitudinal direction, different feeding amounts can be selected according to the steel rail fat edges with different thicknesses, and one-time grinding is achieved; the grinding wheel can move up and down to grind the steel rail fat edge at any position in the height direction, and the overall grinding effect of the steel rail fat edge is good.

Description

technical field [0001] The invention relates to the technical field of railway maintenance equipment, in particular to an automatic grinding machine 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. The above rail grinding machines are mainly divided into two categories, rail surface grinding machines and turnout grinding machines. [0003] 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 ...
