Problems solved by technology

High operating intensity, slow grinding speed and low efficiency
[0008] 2. The grinding wheel for grinding the rail is fed by screw screw, and the grinding amount is adjusted manually. The grinding wheel only grinds in the longitudinal or horizontal direction of the rail, and there is only one grinding direction. The relative position between the grinding wheel and the fat edge of the rail cannot be adjusted. The height of the grinding position is relatively fixed, which affects the overall effect of rail fat edge grinding

Abstract

The invention discloses a fatty steel rail edge polishing machine, and belongs to the technical field of railway maintenance equipment. The fatty steel rail edge polishing machine comprises a rack. The fatty steel rail edge polishing machine is characterized by further comprising a vertical moving device and a horizontal feeding device, wherein the vertical moving device comprises a hanging rack, a ball bearing seat, a ball screw rod and a ball screw nut; a stepper motor and a vertical sliding block are arranged on the rack; the hanging rack is connected with the rack through the vertical sliding block in a sliding manner; the horizontal feeding device comprises a grinding wheel, a gear acceleration tank, a moving platform, a horizontal sliding block, a driving mechanism, a pulse electromotor and a ball screw rod pair; the output shaft of the gear acceleration tank is connected with the grinding wheel; the input shaft of the gear acceleration tank is connected with the driving mechanism; and the horizontal sliding block is connected with the hanging rack in a sliding manner. By adopting the fatty steel rail edge polishing machine, a fatty steel rail edge is polished horizontally, manual adjustment is not needed, different feeding amounts can be selected according to fatty steel rails of different thicknesses, one-time polishing is achieved, the grinding wheel can be moved up and down, any position at any height of the fatty steel rail edge can be polished, and the polishing efficiency and the polishing effects are improved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance equipment, in particular to a rail fat edge grinder. 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 system, grinding wheel, g...
