Railway hardened ballast bed performance testing device

The invention discloses a railway hardened ballast bed performance testing device which comprises an assembly seat mounted on a detection vehicle, an openable rail lifting mechanism mounted on the assembly seat, and a multi-dimensional angle adjusting mechanism mounted at the lower end of the assembly seat and capable of adjusting the position in the transverse direction of a railway. The multi-dimensional angle adjusting mechanism is connected with a pressure applying testing mechanism, and the pressure applying testing mechanism applies pressure to the side face of one side of the measuring pillow or the end face of one end of the measuring pillow or the upper surface of the measuring pillow. According to the invention, efficient detection of different performances of the ballast bed can be realized, the labor intensity of detection personnel is reduced, the operation convenience is improved, the influence of external factors is avoided, and the accuracy of detection data is improved. The method is suitable
