Abstract

The invention discloses a steel rail fat edge grinding device and a steel rail grinding wagon. The grinding device comprises a frame arranged at the bottom of the steel rail grinding wagon, a traction mechanism mounted between the frame and the bottom of the steel rail grinding wagonfor transmitting traction force and driving the steel rail grinding unit to perform grinding operation along a rail, and a steel rail polishing unit mounted on the frame and configured into an end face polishing unit or a cambered surface polishing unit. The end face grinding unit is used for conducting targeted grinding on the fat edge of the inner side of the steel rail, and the cambered surface grinding unit is used for conducting profile enveloping grinding on the steel rail. The technical problems that an existing grinding device is single in strategy, the grinding mode cannot be adjusted according to actual needs, the requirement for large grinding amount cannot be met at the same time, plastic fat edges of the steel rail cannot be removed, and what can be guaranteed is that the profile and the surface roughness of the ground steel rail meet the requirements can be solved.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a rail grinding device and a rail grinding vehicle for grinding inner side damage of rails, especially fat edge grinding. Background technique [0002] As an important component of rail transit, rails are responsible for guiding vehicles to run in a specified direction, and transmitting the impact and load from vehicles to sleepers and fasteners. The strength and safety status of rails directly affect the smoothness and stability of rail transit vehicles. Safety. When subjected to heavy transportation pressure, the rail mainly bears the vertical stress, lateral stress and friction under the wheel load. Under the long-term action of complex stress, the profile of the rail will deteriorate greatly, and diseases such as fat edge and corrugation often appear. [0003] The grinding trolley is the executive mechanism of the grinding operation and the key component ...
