Intelligent grinding trolley for steel rails

The invention discloses an intelligent steel rail grinding trolley which is provided with a walking mechanism capable of achieving upward walking of a steel rail, and positioning of the walking mechanism on the steel rail is achieved through positioning and pressing mechanisms which are designed on the two sides of a trolley frame and composed of a plurality of sets of rolling wheels. The direction of the walking mechanism on the steel rail is changed through a reversing mechanism designed in the center of the walking mechanism. The grinding system is provided with a transverse shaft, a grinding wheel feed shaft and a rotating shaft in the rail length direction, and steel rail grinding is achieved through control of the control system. Meanwhile, a measuring mechanism is further designed, and in the grinding process, a roller at the tail end of a connecting rod is always in contact with the steel rail; the relative position between the grinding head grinding wheel end face and the steel rail face can be calcu
