Steel rail polishing device and steel rail milling grinding machine

Abstract

The invention provides a steel rail polishing device and a steel rail milling grinding machine. The steel rail polishing device comprises a frame, a motor, a driving mechanism and a pressurizing mechanism, wherein the motor is fixedly connected with the frame; the driving mechanism comprises a driving wheel, a driven wheel and a grinding belt connected between the driving wheel and the driven wheel; the pressurizing mechanism comprises two pressurizing wheels, a supporting frame and a pressurizing cylinder; the supporting frame is connected between the two pressurizing wheels; the pressurizing cylinder is connected with the supporting frame; the pressurizing mechanism is located between the driving wheel and the driven wheel; the driving wheel is driven to rotate by the motor; the driven wheel and the grinding belt are driven to rotate by the driving wheel; meanwhile, a piston rod of the pressurizing cylinder extends out, so that a pressing force is applied to the supporting frame; the two pressurizing wheels are driven to descend by the supporting frame and the grinding belt is pressed to the top face and side face of the steel rail, so that the top face and side face of the steel rail are polished, the operation of polishing by enveloping the steel rail by a plurality of grinding wheels from different deflection angles is not required, and the operation efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail grinding device and a rail milling and grinding vehicle. Background technique [0002] With the operation of high-speed and heavy-duty railways and the continuous increase of transportation volume, various damages have appeared on the rails, such as wavy wear of the rails, scratches on the rail surface, peeling of the rail surface, severe wear on the rail side, cracks, and crushing of the rail head. And fat side etc., has had a strong impact on railway transportation capacity and economic benefit. In order to improve the service life of the rails and ensure the safety and comfort of driving, the rails must be maintained regularly to prevent damage and further deterioration. [0003] The rail milling and grinding vehicle is a kind of track repair equipment that repairs the rail by means of milling and grinding. The grinding device of the rail milling and grindi...
