Steel rail cambered surface grinding unit and steel rail grinding trolley
The invention discloses a steel rail cambered surface grinding unit and a steel rail grinding trolley. The steel rail cambered surface grinding unit comprises a transverse moving mechanism; a polishing motor, an output shaft of the polishing motor is connected with a polishing grinding wheel, and the steel rail is polished through the outer circumferential surface of the polishing 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, and 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 polishing motor, and the polishing motor can be driven by the downward pressing mechanism to achieve lifting and downward pressing operation. The technical problems that an existing grinding unit cannot sufficiently grind the profile surface of the steel rail, the steel rail cannot normally pass through a turnout area, the structure is complex, and the grinding deflection angle is limited can be solved.
本发明公开了一种钢轨弧面打磨单元及钢轨打磨小车，钢轨弧面打磨单元包括：横移机构；打磨电机，其输出轴与一打磨砂轮相连，通过打磨砂轮的外圆周面对钢轨进行打磨；用于安装打磨电机，并可活动地连接至横移机构的打磨单元架，通过横移机构能带动打磨电机实现横移操作；连接于打磨单元架与打磨电机之间的偏转机构，通过偏转机构能带打磨电机实现偏转操作；以及连接于偏转机构与打磨电机之间的下压机构，通过下压机构能带动打磨电机实现提升及下压操作。本发明能解决现有打磨单元对钢轨廓形面打磨不充分，无法正常通过道岔区域，结构复杂，打磨偏转角度有限的技术问题。
