The invention discloses a flaw detection trolley constant-thrust rotary connecting rod centering mechanism and a flaw detection trolley, the flaw detection trolley constant-thrust rotary connecting rod centering mechanism comprises a fixed support, a movable support group, a flaw detection wheel group, a driving part and a rotary connecting part, and the rotary connecting part is rotatably connected with the fixed support. The rotary connecting part is arranged between the movable support sets and rotationally connected with the fixed support, and when the distance between the steel rails on the two sides changes slightly, the rotary connecting part can control the movable support sets to move synchronously through the driving part, then the flaw detection trolley wheels on the two sides can be accurately kept synchronous so that the flaw detection trolley wheels adapt to the distance change between the steel rails on the two sides, the central lines of the flaw detection trolley wheels on the left side and the right side coincide with the central lines of the steel rail surfaces, the fixing support is kept in the central position between the two steel rails, and then the automatic centering effect is achieved.

    本发明公开了一种探伤小车恒推力旋转连杆对中机构及探伤车,其中,所述探伤小车恒推力旋转连杆对中机构包括固定支架、活动支架组、探伤车轮组、驱动部件以及旋转连接部件,所述旋转连接部件与所述固定支架的转动连接。本发明通过在活动支架组之间设置有旋转连接部件,且旋转连接部件与固定支架的转动连接,当两侧的钢轨之间的间距出现微小变化时,旋转连接部件通过驱动部件会控制活动支架组同步移动,进而控制两侧探伤小车车轮能够精准保持同步,使得探伤小车车轮适应两侧钢轨之间的间距变化,确保左右两侧的探伤小车车轮的中心线与钢轨轨面中心线重合,使得固定支架保持在两钢轨之间的中心位置,进而达到自动对中的作用。
