Description

Rail fat edge grinding device Technical Field The utility model relates to the field of processing equipment, in particular to a steel rail fat edge polishing device. Background The rail laid by railway has many joints, there is insulating splint in the middle of the joints, insulates adjacent rail, forms interval loop, is the important link of guaranteeing the safe operation of railway, because rail is unidirectional traffic for a long time, rail joint is by wheel extrusion deformation, forms outstanding fat limit, great fat limit can cause the potential safety hazard of adjacent rail short circuit. Therefore, the cutting treatment must be periodically performed on the rail joint fertilizer edge. The current angle mill that adopts the ordinary angle to install the cutting piece additional and polish all, owing to unable location, can only be through angle and the degree of depth that manual control polished, lead to polishing the back and have not uniformity, can harm insulating splint simultaneously, reduced rail maintenance work's efficiency.
