Reset mechanism based on track flaw detection car driving device

The invention relates to the field of steel rail detection, in particular to a resetting mechanism based on a track flaw detection car driving device, which comprises a frame mechanism, a support mechanism, a push rod mechanism and a roller mechanism. The supporting mechanism is rotationally connected with the frame mechanism and can support the frame mechanism; the push rod mechanism is arranged below the head end or the tail end of the frame mechanism; the push rod mechanism can push the frame mechanism to rotate around the supporting mechanism; the roller mechanism is arranged below the frame mechanism and can support the frame mechanism to move. The supporting mechanism and the push rod mechanism do not need to be adjusted to original positions after one-time vehicle body resetting, continuous operation can be conducted in multiple continuous rollover accidents, the complexity of the flaw detection vehicle resetting mechanism is reduced, and operation is easier. 本发明涉及钢轨探测领域，具体涉及一种基于轨道探伤车驱动装置的复位机构，复位机构包括车架
