Abstract

The invention discloses a steel rail cambered surface grinding trolley and a steel rail grinding wagon. The trolley comprises a frame and a steel rail grinding unit installed on the frame. The steel rail grinding unit comprises: a transverse moving mechanism; a grinding motor, wherein an output shaft of the grinding motor is connected with the grinding wheel, and the steel rail is ground through the outer circumferential surface of the grinding wheel; a grinding unit frame which is used for installing the grinding motor and is movably connected to the transverse moving mechanism, and the transverse moving mechanism can drive the grinding motor to achieve transverse moving operation; a deflection mechanism which is connected between the grinding unit frame and the grinding motor, wherein the deflection mechanism can drive the grinding motor to achieve deflection operation; and a downward pressing mechanism which is connected between the deflection mechanism and the grinding motor, wherein the grinding motor can be driven by the downward pressing mechanism to achieve lifting and downward pressing operation. The invention can solve the technical problems that: existing grinding trolleys cannot sufficiently grind the profile surface of the steel rail, cannot normally pass through a turnout area, and are complex in structure and limited in grinding deflection angle.

Description

technical field [0001] The invention relates to the technical field of rail engineering machinery, in particular to a rail arc grinding trolley and a rail grinding car. Background technique [0002] The grinding trolley is the executive mechanism of the grinding operation and the key component of the rail grinding train, which plays an important role in the grinding train. At the same time, the grinding action, quality, efficiency, and advancement of the grinding process required by the grinding train are ultimately reflected by the grinding car. The core part of the grinding trolley is the grinding unit, which directly acts on the rail to achieve the grinding operation, so the mechanism design, rationality and accuracy of the grinding unit are very important. [0003] At present, most of the domestic rail grinding cars use a grindstone plane to grind the rail 23 fixed on the sleeper 24, as attached figure 1 shown. This method drives the rotary motion of grinding wheel 9 ...
