A seat lifting device for an underground coal mine vehicle comprises an installation base used for fixing and a bottom plate used for installing a seat, two connecting rod assemblies are rotationally installed between the installation base and the bottom plate, and the two ends of the two connecting rod assemblies are connected with the installation base and the bottom plate through first pin shafts respectively to form a parallelogram-shaped supporting structure. The mounting base is further rotationally connected with a jacking mechanism used for conducting lifting operation on the bottom plate, and the output end of the jacking mechanism is rotationally connected with the bottom plate. Each connecting rod assembly comprises two connecting plates, and two connecting pipes matched with the first pin shafts are fixedly connected between the two connecting plates. According to the pneumatic lifting seat, the height can be controlled in the lifting process in a pneumatic control mode, the seat balance can be kept, the damping effect is achieved through the pneumatic control mode, and therefore the requirements for controllable lifting height and comfort are met.
