Abstract

The invention discloses a steel rail composite grinding wagon. The steel rail composite grinding wagon comprises a wagon body; a frame, which is arranged at the lower part of the wagon body; and a steel rail composite polishing device, which is mounted on the frame, and comprises an envelope polishing unit and a profiling polishing unit which are arranged above a steel rail in the operation direction, wherein the enveloping and polishing unit is used for carrying out enveloping type polishing on the rail surface of the steel rail by using a cup-shaped grinding wheel, and the profiling grinding unit is used for conducting profiling grinding on the rail surface of the steel rail through a profiling grinding wheel. The technical problem that an existing steel rail grinding wagon cannot meet the requirements of large steel rail grinding amount, wide grinding angle range, high operation efficiency, good operation trafficability and the like at the same time can be solved.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a compound grinding vehicle used for grinding rails. Background technique [0002] During the operation of the train, due to the long-term harsh working environment of the rail, multiple reasons such as dynamic action, natural environment and the quality of the rail itself lead to the continuous deterioration of the rail surface condition and deformation of the rail head, resulting in wave wear, fat edge, peeling, fish scales on the rail surface, etc. Defects affect driving safety. Rail grinding can remove the unevenness of the rail surface and restore the rail head to the original design requirements, so as to effectively improve the wheel-rail relationship, slow down the development of rail surface defects, improve the smoothness of the rail surface, and prolong the service life of the rail. The grinding trolley is the executive mechanism of the grinding ope...
