The invention discloses a dump truck lifting mechanism which comprises telescopic connecting rod devices, wherein each telescopic connecting rod device comprises an upper triangular arm and a lower triangular arm; a telescopic pull rod and a fixed-length pull rod are hinged between each upper triangular arm and the corresponding lower triangular arm; the upper end of each telescopic pull rod is hinged to the upper end of the corresponding upper triangular arm; the lower end of each telescopic pull rod and the lower end of the corresponding fixed-length pull rod are hinged to the upper end of the corresponding lower triangular arm; the upper end of each fixed-length pull rod is hinged to the lower end of the corresponding upper triangular arm; a first connecting rod is fixed in the middle of each upper triangular arm; a second connecting rod is fixed in the middle of each lower triangular arm; the telescopic connecting rod devices are connected by the first connecting rods and the second connecting rods; a hydraulic cylinder is hinged between each first connecting rod and the corresponding second connecting rod; the mechanism composed of the telescopic connecting rod devices and the hydraulic cylinders can achieve twice lifting. The dump truck lifting mechanism can achieve twice lifting amplification, achieve large-angle lifting by a shorter stroke lifting cylinder, occupy smaller space, lower the center of gravity of the dump truck, and improve the driving stability and lifting stability of the dump truck .
