The invention provides an axle lifting device of a semitrailer, and relates to the technical field of semitrailer auxiliary tools. The axle lifting device of the semitrailer comprises three pairs of tires, rear axle shafts are arranged in the centers of the side walls of the three pairs of tires respectively, the other ends of the three rear axle shafts penetrate through the three pairs of tires respectively, rear suspensions are arranged in the centers of the two pairs of tires close to the rear side, the two ends of the three pairs of rear axle shafts are connected with the lower ends of the rear suspensions respectively, and the rear suspensions are connected with the rear suspension. Front axle plate springs are arranged on the upper sides of the two ends of the rear axle shaft on the side walls of the pair of tires close to the front side correspondingly, the lower ends of the two front axle plate springs are connected to the upper end of the rear axle shaft through front light axles correspondingly, and the upper ends of the two front light axles are connected with air bag lower fixing plates correspondingly. The upper ends of the two air bag lower fixing plates are connected with small air bags respectively. The tires are lifted after the axle is lifted during use, so that the tire wear is reduced, the tires are saved, and the fuel consumption is reduced.
