Abstract

The invention relates to a steel rail grinding machine which comprises a steel rail top surface grinding mechanism, a steel rail head side surface grinding mechanism, a steel rail triangular region grinding mechanism, a steel rail bottom grinding mechanism and a travelling line roller, wherein a steel rail is ground by the steel rail top surface grinding mechanism, the steel rail head grinding mechanism, the steel rail triangular region grinding mechanism and the steel rail bottom grinding mechanism in a process of sliding on the travelling line roller, wherein the steel rail bottom grinding mechanism comprises a center base, a base plate is fixedly connected onto the center base, a Z-direction oil cylinder and a Z-direction guide rail are arranged on the base plate, the Z-direction oil cylinder drives a Z-direction sliding base to reciprocate on the Z-direction guide rail; a Y-direction oil cylinder and a Y-direction guide rail are fixedly arranged on the top surface of the Z-direction sliding base, the Y-direction oil cylinder drives the Y-direction sliding base to reciprocate on the Y-direction guide rail; a hydraulic motor is vertically arranged inside the Y-direction sliding base, and an output shaft of the hydraulic motor is fixedly connected with a rail bottom grinding head.

Description

Technical field [0001] The invention relates to the field of railway equipment, in particular to a rail grinding machine. Background technique [0002] After the rail is welded, the rail welding seam must be milled first, and there are tool marks at the bottom of the rail after milling. After milling is completed, the rail needs to be polished to eliminate tool marks and residual weld margins at the bottom of the rail, and to improve the surface flatness of the rail. [0003] figure 1 It is an explanatory drawing of each area of ​​the rail. [0004] At present, the rail grinding method is mostly manual hand-held grinder for grinding. During the grinding process, the grinding amount is controlled by manual experience, resulting in low grinding accuracy. At the same time, a large amount of dust will be generated during the grinding process. Although the staff wears protective devices, the harm to health is still great. [0005] After the rail is polished, flaw detection is required. ...
