Description

Technical Field

[0001] The invention relates to an unmanned mining truck frame and an upper structure, belonging to the technical field of new energy electric unmanned trucks for mines. Background Art

[0002] In recent years, China's mine construction has entered the fast track of unmanned and intelligent development. Combined with the general requirements of the national dual-carbon strategy, new energy unmanned mining trucks have become a magic weapon for cement companies and mining construction, and are also a good helper for energy conservation in enterprises. It is understood that new energy unmanned electric mining trucks have been used in China. The current industry recommended standard for new energy unmanned electric mining trucks is that each vehicle can carry 200-600 tons, which is 5-12 times the carrying capacity of ordinary trucks (regulations require that the vehicle's curb weight shall not exceed 49 tons). The main reason is the improvement of the frame's carrying capacity and the cargo box's carrying capacity.

[0003] Due to the harsh working environment of unmanned mining trucks, and the fact that most of the items transported are irregular mining rocks and other items, the sides and bottom of the cargo box will be subject to huge impact forces when loading. Therefore, in order to ensure the structural strength and service life of the cargo box, the bottom plate and side plates are welded with multiple layers of solid steel plates to withstand the impact force brought by the rocks and prevent deformation or even overturning due to major impact forces. Therefore, most of the weight of unmanned mining trucks is concentrated on the frame, cargo box, and the connection between the frame and the cargo box. Therefore, the unmanned mining trucks in the prior art have the problem of excessive weight of the cargo box and frame, so that most of the electric energy is used to overcome the kinetic resistance of the frame and cargo box of the unmanned mining truck itself, which reduces the economic efficiency of electric energy and requires frequent charging.

[0028] Specifically, the floor assembly 1 includes a floor 6, a front cross beam 7, a rear cross beam 8, a side longitudinal beam 9 and a main longitudinal beam 10. There are two side longitudinal beams 9, and the two side longitudinal beams 9 are symmetrically welded and fixed on the left and right sides of the bottom surface of the floor 6. The front cross beam 7 is welded and fixed on the front side of the bottom surface of the floor 6, and the two ends of the front cross beam 7 are respectively welded and fixed to the front ends of the two side longitudinal beams 9.

[0039] Preferably, the front cross beam 19 is connected to the second middle reinforcing cross beam 20 via two longitudinal support rods, and the second middle reinforcing cross beam 20 is connected to the front cross beam 7 via four longitudinal support rods.

[0040] The front side plate 18 is a solid steel plate, and the thickness of the steel plate is set according to demand.
