As shown in Figure 1, a kind of inclined rail elevating device of the present utility model, comprises the mounting frame 11 that inclined rail 1 is installed, lifting car 2 and traction mechanism, and inclined rail 1 is fixedly and obliquely installed on the mounting frame 11. The lift car 2 is provided with a set of guide wheels to bear its eccentric load. At the same time, the guide wheels also have a guiding effect during operation. The lift car 2 is prone to failure due to uneven placement of materials on the lift car during the lifting process along the ramp 1. Unbalanced loads are generated, and the set of guide wheels is arranged to eliminate or reduce the unbalanced loads so that the lifting vehicle 2 can run smoothly. The traction mechanism includes at least one group of pulley blocks, power equipment 15 and steel wire rope 9 for providing power, and the power equipment 15 can adopt a hoist, which is conducive to retracting the wire rope 9 . One end of steel wire rope 9 is connected with power equipment 15, and the other end of steel wire rope 9 walks around block of pulleys and drives hoist car 2 to move up and down along inclined rail 1.

As shown in Figures 1 to 3, the lift truck 2 includes a front part 20 of the frame beam and a rear part 21 of the frame beam, and a material baffle 7 is arranged on the front part 20 of the frame beam, and the material baffle 7 is carried out when the scrap steel is unloaded. Guide, but also shield the material from splashing. The frame beam rear portion 21 is provided with a support frame 5, the support frame 5 is a triangular support frame, and a loading hopper 6 is installed on the support frame 5, and the loading hopper 6 is used for loading materials, and the support frame 5 is arranged on the vehicle frame beam rear portion 21, so that the weight of the material acts on the frame beam rear portion 21 through the support frame 5. The rear part 21 of the frame beam bears relatively high pressure, and two rear wheels 4 are respectively installed at both ends of the rear part 21 of the frame beam to improve its load-carrying capacity, and a front wheel is respectively installed at both ends of the front part 20 of the frame beam 19.
